(54) Title: ORTHOPAEDIC RATCHETING FORCEPS 



OS 
ON 



o 




(57) Abstract: An orthopaedic ratcheting forceps, especially for fixation of fractures, comprises two handles (2, 12), wherein a first 
catching element (5) is mounted pivotally with one handle (2 or 12) and wherein a complementary catching element (25) is mounted 
on the other handle (12 or 2). The forceps can assume only two stable settings which can be switched with a single hand, one closed 
setting within which the jaws (4) of the forceps can only be further closed and an open setting within which the handles (2, 12) of the 
forceps are freely movable, so that the forceps can be opened as well as closed. In one handle (12) a leaf spring (28) is provided and 
biased between two mounting points (27; 13) which spring (28) is mounted between abutting side walls (14, 24) within said handle 
(12). Furthermore a lever end (25) connected with one of the catching elements (26) engages the spring (28) and through movement 
of the activation element (32) the lever end (25) and/or the spring (28) is switchable between the closed setting and the open setting.

Orthopaedic ratcheting forceps 

5 The invention relates to an orthopaedic ratcheting forceps and 
specifically to a forceps used to manipulate and hold the bone 
for fixation of fractures. 

The prior art shows a multitude of manipulating devices for use 
10 during orthopaedic surgery. An exemplary forceps according to 
the preamble of the main claim of this invention is shown in WO 
89/06939 (U.S. Patent No. 4,896,665). Beside the fact of the 
possibility to interchange tips of the forceps as shown in said 
application, another important practical point for the surgeon 
15 is the possibility to change the attack point of the forceps, 
i.e. to have a reversible ratchet mechanism. The advantage of 
the ratchet according to said PCT application resides in the 
fact, as shown in Pig. 9, 8 and 9, that through switching a 
lever through three switching positions the forceps can move 
20 freely (Fig. 9, neutral position) or in either direction (Fig. 
10 or Fig. 11, respectively) . Although this approach facilitates 
the work of the surgeon, it has been found not to be entirely 
satisfactory. The mechanism is difficult to manipulate with only 
one hand. 

25 

Another known forceps is disclosed in US 5,674,244. The pliers 
according to this document have the advantage that almost all of 
the ratcheting structure is within the handles and do not extend 
beyond the outer form of the instrument. There is provided a 
30 spring to exert the counter-force to open the pliers, when the 
release button is pushed. The advantage of reduced dimensions of 
the forceps goes with the practical disadvantage in activating 
the locking device of the pliers between the handles.

In view of this prior art the object of the invention is to pro- 
vide an orthopaedic ratcheting forceps for a surgeon giving him 
better control for the locking device and at the same time 
5 strengthen the security of the pliers. 

This object is achieved for a forceps through the features of 
claim 1 or claim 7. 

10 Further objects and advantages are achieved through the features 
of the subclaims and exemplary embodiments of the invention are 
disclosed in the following description in which:

Fig. 11 is an enlarged view of the lever portion within circle IX 
in Fig. 10 , 

Fig. 12 is an enlarged view of the locking portion within circle

Fig. 13 is a view in side elevation of a forceps according to a 
third embodiment of the invention with the locking device 
in an open setting, and 
Fig. 14 is a view in side elevation of the forceps according to 
10 Fig. 13 with the locking device in a closed setting. 



Fig. 1 shows a view in side elevation of a forceps 1 according 
to a first embodiment of the invention with the locking device 
in an open setting, i.e. in a setting in which the handles 2 and 
15 12 are freely movable about an pivot point 3. The forceps 1 has 
jaws 4 comprising sharp points provided to enter into bone mate- 
rial and/or surgical plates and bone material. It is clear that 
other configurations may be chosen, e.g. that the jaws comprise 
internal teeth . 

20 

On the inner side of handle 2, a shaped rod 5 is pivotally 
mounted by means of a pin 6. A leaf spring 7 pushes the rod 5 
from the outer side of the handle 2 into the direction or to- 
wards the pivot point 3 . In a more simple embodiment the spring 

25 7 may be omitted, especially if the guiding bore 8 (not shown) 
within the second handle .12 is sufficiently narrow. The rod 5 
comprises a number of catching elements or ratchet teeth 10. 
These may comprise grooves in a transversal direction to the 
longitudinal axis of the slightly curved rod 5. The rod 5 is 

30 preferably slightly curved, having a radius of curvature equiva- 
lent to the distance from the pivot point 3. The grooves or 
notches (=catching elements 10) are provided on the inside of 
the rod 5 , i.e. directed towards the pivot point 3 . 



WO 2004/041099 ^B PCT/CH2003/000718 



As mentioned above, within the second handle a guiding bore 8 is 
located with e.g. rectangular dimensions to accommodate the rec- 
tangular rod 5. If the rod 5 is more or less round then the 
5 guiding bore 8 may be cylindrical, or a rounded slit etc. . 

The second handle 12 comprises a second pivot point 13 in the 
neighborhood of the bore 8, dividing the handle 12 in one fin- 
gerhole part 32 and in one jaw part 22, hinged together at said 

10 second pivot point 13. This allows for a locking structure 2 0 to 
be mounted between the first and second pivot points 3 and 13, 
respectively, of the handle 12. The jaw part 22 of the second 
handle 12, nearby the pivot point 13, splits of in two arms 14 
and 24 between which the end 25 of the fingerhole part 32 is lo- 

15 cated. The two arms 14 and 24 join together in one end point 
which may advantageously be in the vicinity of the pivot point 
13. Said end 25 can be moved between the inner sides of the arms 
14 and 24. In the position of Fig. 1 where end 25 is positioned 
toward arm 14 a nose 26 integrally, mounted on fingerhole handle 

20 part 32, is free and does not engage the catching elements 10 of 
rod 5. 

Between two end points (27 and here pivot point 13) of the arms 
14 and 24, respectively, is provided a leaf spring 28. Leaf 
25 spring 28 engages the end 25 of fingerhole part 32 and is part 
of the lever and locking mechanism of the ratchet. In the pre- 
ferred embodiment, spring 25 is made of spring steel and sup- 
plies sufficient force to maintain the nose 26 into engagement 
with the teeth of arm 5 when deflected towards arm 24. 

30 

Fig. 2 is an enlarged view of the lever portion within circle II 
in Fig. 1. Same features in all drawings always have the same 
reference numerals. Spring 2 8 is mounted with the transversal 



WO 2004/041099 




PCT/CH2003/000718 



direction of the leaf perpendicular to the drawing plane and 
therefore parallel to the axes of the pivot points- 3 and 13. 
Therefore two noses 29 provided parallel one to another and en- 
compassing the leaf spring 28 are mounted on the end 25 and ex- 
5 tending into the space between the arms 14 and 24 provide guid- 
ing means for the spring 28. Since the spring 28 is biased, i.e. 
longer than the length of a direct line between the end points 
27 and 13 of the arms 14 and 24, the end 25 can only take two 
stable positions, one open setting according to Fig. 1 (de- 
10 fleeted towards arm 14) and one closed setting according to Pig. 
3 (deflected towards arm 24) . The noses 29 may be small bolts or 
cylinders with enough play between them to allow the movement of 
the spring 28. The surface of the bolts 29 on the opposite side 
to the position of the spring 28 can be directly used to abut 
15 against the arm 14 or arm 24, respectively. 

Fig. 3 is an enlarged view of the locker portion within circle 
III in Fig. 1. The teeth 10 comprise two different slopes 70, 
71. Slope 71, which is the slope oriented towards fixation point 
20 6, is more or less perpendicular to the current longitudinal 
axis of rod 5. The other slope 70 is inclined in direction of 
fixation point 6 with an angle between preferably 30 and 60 de- 
grees in comparison to the direction of slope 71. 

25 Fig. 4 shows a view in side elevation of the forceps 1 according 
to Fig. 1 with the locking device in a closed setting, i.e. in a 
setting in which the handles 2 and 12 are only movable about the 
pivot point 3 in a direction closing the jaws 4 of the forceps 
1. Fig. 5 is an enlarged view of the lever portion within circle 

30 V in Fig. 4. As can be seen in comparison of the two settings of 
the forceps in Fig. 1 and 4, the handles 2 and 12 are freely 
movable (i.e. they can be opened). There can be an additional 
spring, not shown in Fig. 1 and 4, between handles 2 and 12 in 



WO 2004/041099 




PCT/CH2003/000718 



6 

the vicinity of pivot point 3, urging the handles 2 and 12 
apart. Otherwise (without said spring) the forceps may be opened 
by the surgeon as he would do with scissors. Upon pushing the 
handle 12 and especially the fingerhole part 32 towards the 
5 other fingerhole part 42, a moment is exerted upon the spring 28 
through the lever provided through second pivot point 13 and the 
lever length to the end 25. This moment pushes the spring 28 out 
of the stable open setting as shown in Fig. 1 towards the second 
stable setting as shown in Fig. 4, the closed setting. Through 
10 the movement of the fingerhole part 32 relative to the jaws part 
22 of the handle 21 the nose 26 engages one of the catching ele- 
ments 10 of rod 5. Therefore upon releasing the fingerhole parts 
32 and 42 # a counter pressure upon the jaws 4 of forceps 1 will 
not open the handles 2 and 12 because the forceps 1 is in a sta- 
15 ble closed setting. However, the surgeon has the possibility to 
further close the fingerhole parts 32 and 42. To ensure the pos- 
sibility of this movement the catching elements 10 of rod 5 and 
the nose 26 are formed asymmetrically, ensuring that the nose 26 
can glide from one catching element 10 to the next one which is 
20 nearer to the pivot point 6 while forbidding the inverse move- 
ment. 

. The surgeon can also very easily release the grip of the forceps 
through pushing the fingerhole 32 apart from the fingerhole 42, 

25 disengaging the nose 26 from the catching elements 10, when the 
setting according to Fig. 1 is reached. This means that he con- 
trols the opening and closing of the forceps 1 through simple 
manipulation and relative movement of the fingerhole parts 32 
and 42. There is no need for a separate switch, button or re- 

30 lease mechanism. 

.Fig. 6 is an enlarged view of the locker portion within circle 
VI in Fig. 4. Two teeth 10 with their two neighbouring different

slopes 70 , 71 are in engagement with the nose 26, which prefera- 
bly has a complementary form to the groove 72 which is formed by 
the slopes of adjacent teeth 10 , therefore blocking the movement 
of the rod 5 in one direction and allowing said movement in the 
other direction. 

The embodiment according to Fig. 1 to 4 is not the only possi- 
bility to achieve such advantageous handling of a forceps. Fig. 
7 is a view in side elevation of a forceps 41 according to a 
second embodiment of the invention with the locking device in an 
open setting. All features within the embodiment of Fig. 7 hav- 
ing similar features within the embodiment according to Fig. 1 
have the same reference numerals. Fig. 8 show an enlarged view 
of the lever portion within circle VI in Fig. 7 and Fig. 9 is an 
enlarged view of the locking portion within circle VII in Fig. 
7. Within this embodiment a release button 42 is provided in 
parallel to one handle 12. The principle of the forceps 41 is as 
follows. A cylindrical locking element 3 5 is provided on or in- 
tegral to handle 2. This locking element 35 comprises at least a 
rough surface, preferably comprising small transversal grooves 
36. A complementary locking element 3 7 is provided with the re- 
lease button 42 being realised as a lever arm extending in par- 
allel to handle 12. The complementary locking element 37 com- 
prises grooves or teeth 36 which are arranged along a curve with 
a changing curvature, i.e. the radius of curvature becomes 
greater between the position of the element 37 which is named 
the open setting in relationship to the position which is named 
the closed setting. 

The open setting of Fig. 7 is achieved through a biased spring 
28 extending between one end point 27 inside a lengthy slit be- 
tween two webs 14' and 24 ' and another endpoint 57 near the piv- 
oting point 33. In order to achieve the closed setting as shown

in Fig.. 10 showing a view in side elevation of the forceps 41 
according to Fig. 7 with the locking device in an closed set- 
ting, and as the detailed view of Fig. 11, an enlarged view of 
the lever portion within circle IX in Fig. 10, and Fig. 12, an 
5 enlarged view of the locking portion within circle X in Fig. 10. 
Through a pivoting of the lever 42 away from the handle 12 the 
two complementary surfaces 35 and 37 mutually engage and through 
the special form of the surface 37 the forceps 41 can not open 
anymore since the spring 28 now urges the lever 42 in the second 
10 stable setting, the closed setting. 

Finally Fig. 13 shows a view in side elevation of a forceps 61 
according to a third embodiment of the invention with the lock- 
ing device in an open setting, and Fig. 14 shows a view in side 
15 elevation of the forceps 61 according to Fig. 13 with the lock- 
ing device in a closed setting. 

On the inner side of handle 2, a shaped rod 5 is swivel -mounted 
by means of a pin 6. The guiding bore 8 within the second handle 

20 12 accepts the rod 5. The rod 5 comprises a number of catching 
elements 50. These may comprise grooves in a transversal direc- 
tion to the longitudinal axis of the slightly curved rod 5. The 
rod 5 is preferably slightly curved, having a radius of curva- 
ture equivalent to the distance from the pivot point 3. The 

25 grooves or notches (=catching elements 10) are provided on the 
inside of the rod 5, i.e. directed towards the pivot point 3. 
Within the second handle 12 is located a bolt 48, which is 
pushed in direction of the rod 5 through a spring 47 which may 
be a disk spring and which is placed in the second handle 12 be- 

30 tween the bolt 48 and the pivot point 3 acts to move surface 46 
of rod 5 towards surface 46 of an element 37. In the open set- 
ting shown in Fig. 13 the surfaces 46 of element 3 7 and rod 5 
are not in engagement, whereas in Fig. 14 the element 37 is 



WO 2004/041099 




PCT/CH2003/000718 



pushed inside the forceps 61 therefore bringing the surfaces 46 
in contact one to another achieving the same function as within 
the second embodiment, i.e. preventing the jaws 4 from opening 
but allowing closure. The arrangement according to Fig. 13 and 
12 allows a further compression, just gliding the surfaces 46 
one against another. However, there is no backwards travel, 
which can only be achieved through pushing the element 37 to- 
wards the outside through pushing the. nose 49 in either direc- 
tion (from Fig. 13 to Fig. 14 and vice versa) . 



10 



In all embodiments the release or fixation element is directly 
usable when gripping the forceps, either through manipulation 
within the fingerholes 32 as in the first embodiment, or through 
a release lever 42 in parallel to the handle as in the second 
15 embodiment, or through a bolt 48 releasing element, provided in 
parallel to the second handle as in the third embodiment. 

One of the advantages of the embodiment according to Fig. 1 is 
the possibility to switch from the open to the closed setting 

20 through movement of the handles. There is no additional button 
or lever to be manipulated. Therefore the surgeon can switch the 
device into the closed setting, engage the device within the 
body to be gripped, close the jaws 4 further, while within this 
closed setting the surgeon is sure that one position of the jaws 

25 reached they will not open any more. If now the grip has to be 
loosened, the surgeon can switch from the closed setting to the 
open setting without leaving the gripping holes of the handles. 
Then he opens the jaws and continue to work on the same body to 
be gripped or another without loosing time. 

30 

The second advantage of the embodiment shown in Fig. 7 to 10 is 
the reduced space requirement and the button 49 is still easily 
reached since mounted in a natural position for the hand. This 



WO 2004/041099 




PCT/CH2003/000718 



10 



result can be reached through the definition of the surfaces 3 6 
within the elements 35 and 37, respectively. In the figures one 
element has a cylindrical' curvature while the other has a chang- 
ing radius of curvature. In the open setting (freely movable 
jaws 4) the two elements are in a small distance one from an- 
other when the distance is measured on the straight line between 
the two axes. When the button 42 is moved to the closed setting, 
the element 37 is rotated around the axis 33. Therefore the dis- 
tance changes and eventually becomes zero. The surfaces 36 are 
engaging one another. When the surgeon now would try to open the 
jaws, i.e. move the second handle 2 away from the first handle 
12, the two surfaces would rotate around the axes 33 and 3, re- 
spectively. But this rotation would diminish further the dis- 
tance between said surfaces since one of the elements has a 
15 growing radius of curvature in this direction of rotation re- 
sulting in a blocking state. The further closing of the jaws 
through movement of the handles would move the elements in a di- 
rection where at least one element has a diminishing radius of 
curvature thus allowing this movement.

In order to ensure the best engagement of the surfaces they are 
provided with microgrooves or grooves in a direction perpendicu- 
lar to the drawing sheets.
