Definitions

  • the present invention relates to a surgical device for immobilizing a patient's operated-on ankle.
  • This device is intended to immobilize the patient's ankle joint during a surgical procedure on this ankle, without the invention in any way being limited to any specific type of surgical procedure.
  • the ankle is immobilized via a device according to the invention so that it can undergo an arthrodesis or alternatively so that it can be fitted with a joint prosthesis.
  • US-A- 2006/0229730 proposes a surgical tool that allows the ankle to be aligned with the tibia when fitting a specific ankle prostheses: the patient's foot is placed on an elaborate support which allows fine adjustment of the anterioposterior and medio- lateral orientation of the ankle with respect to a plate on which the plantar face of the foot rests, while the patient's leg rests against a dedicated rest.
  • this rest is mechanically independent of the aforementioned support insofar as the unadjustable reference for the positioning between the ankle and the tibia is obtained using an intramedullary nail introduced through the ankle from the side of the support opposite to the foot, and as far as the tibia.
  • the subject of the invention is a surgical device for immobilizing a patient's operated-on ankle as defined in claim 1.
  • the idea underlying the invention is that of positioning, relative to one another, the foot and leg associated with the operated-on ankle in a way that is simple, effective and adjustable, without in any way impeding the movements of the surgeon.
  • the foot and the leg here considered with their anatomical meaning, that is to say as denoting respectively the distal segment of the lower limb and that segment of this lower limb that lies between the knee and the foot, are respectively placed at rest and resting against the plate and the frame of the device according to the invention, while this plate and this frame are mechanically connected such that they can move in order, prior to the actual acts of surgery or, alternatively, peroperatively, to adjust the positioning of the frame with respect to the plate.
  • the device fits a very wide range of foot and leg sizes and does so with the same efficacy insofar as the operated-on ankle is immobilized reliably in a configuration chosen by the surgeon.
  • This also means that there are various possible routes via which the surgery can be performed on the operated-on ankle, and in particular, there are at least one anterior route, one lateral route, and one posterior route, depending on the relative positioning of the frame and of the plate, which positioning is adjusted and locked.
  • - figure 1 is a perspective view of a device according to the invention, shown in combination with a schematic depiction of certain bones of the foot and of the leg of a patient who is undergoing an operation on his ankle;
  • - figure 2 is an elevation on Il of figure 1 ;
  • FIG. 3 is an elevation on III of figure 2, without including the bones shown in figures 1 and 2;
  • figure 4 is an elevation on IV of figure 3;
  • - figures 5 and 6 are sections on V-V and Vl-Vl of figure 3, respectively;
  • - figures 7 and 8 are views respectively similar to figures 1 and 2, showing the device in a different configuration of use to that shown in figures 1 and 2; and
  • Figures 1 to 6 depict a surgical device 1 designed to immobilize the ankle C of a patient during a surgical procedure on this ankle.
  • the ankle C forms the joint between the foot P and the leg J of a patient, only some of the bones of which have been depicted in these figures, those depicted being, inter alia, the talus A and the calcaneus B of the foot P and the tibia T of the leg J.
  • the device 1 comprises three main sets of components, namely a plate 10, a frame 20 and mechanical means 30 connecting this plate and this frame, which will be detailed gradually hereinafter.
  • the plate 10 has a parallelepipedal overall shape of small thickness.
  • the length and width of the plate, particularly of its flat upper face 10A intended to face upwards in use, are sized so that the plantar face P A of the foot P can rest on this face 10A as depicted in figures 1 and 2.
  • the anterioposterior direction of the foot runs substantially parallel to the longitudinal direction of the plate 10, being more or less centered relative to one another, insofar as neither the front and rear ends of the foot, nor the medial and lateral edges thereof lie outside the peripheral contour of the face 10A.
  • the plate 10 thus forms a stable and precise reference plane on which to position the foot P.
  • the plate 10 is made of a radio-transparent material so that the device 1 can be used during surgical procedures carried out under radioscopy or fluoroscopy.
  • the rear longitudinal part of the plate 10 that is to say that part of this plate on which the rear of the foot is intended to rest when the device 1 is in service, has, passing right through its thickness, a number of holes 11 which thus each connect the top face 10A and the opposite underside 10B of the plate 10.
  • Each of these holes 11 is dimensioned to accept a nail, not depicted, for osseus positioning in the foot P: in particular, one or more of such nails may be used to interface with the calcaneus B of the foot P having passed through one or more of the holes 11. In this way, the foot P is firmly immobilized with respect to the plate 10.
  • the top face 10A of the plate 10 has a visual identification pattern, here in the form of a grid pattern 12 (figure 1 ), the elementary elements of which are identified by a series of letters and a series of numerals respectively inscribed in the widthwise direction and the lengthwise direction of the plate 10.
  • each element of the grid pattern 12 corresponds to a geometric square, with a side length of one centimeter. Other geometric shapes for these grid pattern elements, or, more generally, for these elements for visually dividing up the face 10A are conceivable.
  • This grid pattern 12 thus forms a pattern that the surgeon can see, allowing him to identify, on the face 10A, how the foot P is positioned.
  • this spatial identification is used to position the foot P in a preset position with respect to the plate 10 at the start of the surgical procedure or alternatively to return to a precise position during the surgical procedure, if, for example, it has been necessary to temporarily shift the foot P relative to the plate 10.
  • the plate 10 In its front part, the plate 10 is equipped, on each of its lateral edges, with projecting pegs 13 designed to attach a strap, not depicted, for strapping the front end of the foot P as will be better understood later on.
  • the frame 20 is chiefly made up of a bent rigid rod that forms a U-shaped overall structure facing towards the plate 10.
  • This rod structure thus comprises two parallel branches 21 which are separated from one another by a distance substantially corresponding to the width of the plate 10 and of which the free ends
  • the aforementioned rod structure also comprises a bar 22 connecting the ends 21 2 of the branches 21 which are the opposite ends to their free end 2I 1 , thereby running in a direction both parallel to the face 10A of the plate 10 and perpendicular to the longitudinal direction of this plate, as is clearly visible in figure 3.
  • the frame 20 is equipped with a roller 23 mounted coaxially on the bar 22 such that it can rotate freely on itself, as indicated by the arrow F 2 3 in figure 5.
  • This roller 23 is thus designed to form a support for the leg J, as depicted in figures 1 and 2.
  • it is the posterior soft parts, not depicted, of the leg J which rest directly on the roller 23 in the configuration of use of the device 1 considered in these figures.
  • the roller 23 advantageously has the overall exterior shape of a diabolo, as is clearly visible in figure 3.
  • the frame 20 is equipped with two lugs 24 for osseus fixation in the leg J, these being mounted respectively on the main part 21 3 of the branches 21 so that they can rotate freely about the central longitudinal axis X 21 -X 21 of these branches 21 as shown in figure 6.
  • Each of these lugs 24 delimits, at its opposite end to the end that is mounted on the main part 21 3 of the corresponding branch 21 , a through-hole 24A designed to accept an osseus positioning nail, not depicted.
  • the aforementioned nail is intended to interface, preferably, with the tibia T of the leg J, having been passed through the hole 24A in the lug 24, it being pointed out that the direction in which this nail is implanted through the hole 24A is directly dependent on the angular position of the lug 24 about the axis X21-X21, this position being set by the surgeon.
  • the frame 20 is also equipped with protruding pegs 25 situated in the main part 21 3 of the branches 21 so that these pegs collaborate, through mutually complementing shapes, with associated perforations 41 in a strap 40 used to strap the leg J to the frame 20.
  • the strap 40 is used to strap the leg J, wrapping around the anterior face of the leg J with the main part of the strap while the opposite ends of the strap are attached to the respective pegs 25 of the branches 21 , the strapping tension obtained by the strap 40 being adjusted by selecting which perforations 41 to engage with the pegs 25.
  • This immobilizing of the leg J with respect to the frame 20 by strapping as shown in figures 1 and 2, also explains how the front end of the foot P is immobilized with respect to the plate 10 by strapping using a strap similar to the strap 40 that is attached to the pegs 13.
  • the strap 40 is made of a flexible material such as a silicone rubber.
  • the means 30 comprise a carriage 31 essentially arranged under the plate
  • This carriage 31 comprises two brackets 32 respectively supporting the branches 21 of the frame 20, these two brackets being joined together rigidly by a spacer piece 33 positioned facing the underside 10B of the plate 10.
  • Each bracket 32 is accommodated with sliding in a guide slot 14 delimited by the plate 10, through its thickness.
  • These two slots 14 run in a straight line in the longitudinal direction of the plate 10, being located one along each of the two longest opposite sides of the plate as is clearly visible in figure 4.
  • brackets 32 By sliding in each of these slots 14, the brackets 32 can be moved, relative to the plate 10, translationally along respective axes Xi 4 which in this instance run in the longitudinal direction of this plate and can do so, at most, between the two opposite longitudinal ends of the slots 14, as indicated by the arrows F 32 in figure 4. Furthermore, in the configuration of use considered in figures 1 to 6, the brackets 32 occupy the respective rear ends of the slots 14, which is the same as saying that the carriage 31 has undergone translational movement to the rear end of the plate 10.
  • the carriage 31 is associated with a locking mechanism 34 allowing the ability of the carriage to effect translational movement relative to the plate 10 to be prevented reversibly.
  • this mechanism 34 is in the form of a manually operated lever of which the end 34i , the opposite end to its free end, is mounted such as to pivot on the main part of the spacer piece 33, as is clearly visible in figure 5: this lever end 34i forms a cam that wedges the spacer piece 33 with respect to the plate 10 such that when the lever 34 is running substantially perpendicular to the plate 10, as depicted in chain line in figure 5, the spacer piece 33, and therefore the carriage 31 , are free to undergo translational movement with respect to the plate, through the sliding of the brackets 32 in the slots 14, which is the same as saying that the mechanism 34 is unlocked, whereas when the aforementioned lever is running substantially parallel to the plate, the spacer piece 33 is fixedly wedged by the end 34i against the underside 10B of the plate, which is the same as saying that the mechanism 34 is locked,
  • the means 30 further comprise two wheels 35 respectively mechanically interposed between the branches 21 and their support bracket 32. More specifically, as depicted in figure 6, each wheel 35 is rigidly connected to the corresponding branch 21 , for example by pushing the end 2I 1 of this branch into a complementary bore 35i delimited radially in the thickness of the wheel 35. At the same time, each wheel 35 is housed in a complementary housing 32 ⁇ delimited by the corresponding bracket 32, this housing 32 ⁇ being substantially in the shape of half a disk coaxial with the wheel 35 when the means 30 are in the assembled state.
  • Each wheel 35 is thus mounted on the bracket 32 such that it can rotate on itself about its central axis X35, the two axes X35 of the wheels being substantially aligned with one another, running both parallel to the top face 10A of the plate 10 and perpendicular to the longitudinal direction of this plate, as shown by figure 3.
  • the frame 20 is assembled with the carriage 31 such that it can pivot about coincident axes X35 as indicated by the arrow F 35 in figure 6.
  • the pivoted position of the frame 20 about the coincident axes X 35 can be modified.
  • the means 30 further comprise a locking mechanism 36, separate from the mechanism 34, to prevent the wheels 35 from rotating with respect to their bracket 32.
  • this mechanism 36 includes a bent rod 36i, which runs lengthwise under the plate 10 transversely to the longitudinal direction of this plate, and the opposite ends of which each bear a pawl 362 shaped to be housed through complementary shapes in one of a number of radial bores 352 delimited by the wheel 35 and opening onto the external periphery of this wheel, as clearly visible in figure 6.
  • the wheel 35 is free to move in terms of rotation about the axis X 35 inside the bracket 32 whereas, when the pawl occupies one of these bores, as in figure 6, it prevents the wheel 35 from rotating.
  • the pawl 36 2 is made to disengage from the external periphery of the wheel 35 manually using the rod 36i, whereas the pawl is made to engage with one of the bores 35 2 by releasing this rod 36 1 ; a compression spring 36 3 being interposed between the pawl and a dedicated part of the bracket 32.
  • the frame 20 has, on the one hand, undergone maximum translational movement rearward with respect to the plate 10, the brackets 32 occupying the rear ends of the guide slots 14 and, on the other hand, has been pivoted to 90° with respect to the plate 10, the pawl 362 occupying the bore 352 situated in the radial continuation of the bore 35i, as shown in figure 6.
  • the surgeon can be sure that the leg J is positioned precisely, resting against the frame 20, with respect to the foot P, resting on the plate 10, so that he can perform surgery on the ankle C via an anterior route, which is particularly well accessible and clear of any component belonging to the device 1.
  • This positioning is fixed reliably by virtue, on the one hand, of the fact that the foot P is immobilized with respect to the plate 10 under the action of one or more osseus positioning nails housed in one or more of the holes 11 and/or under the action of a strap that straps the front end of the foot and is attached to the pegs 13 and, on the other hand, of the fact that the leg J is immobilized resting against the frame 20 under the action of the strap 40 and/or of one or two tibial positioning nails fitted through the lugs 24. Furthermore, this positioning is reproducible, by virtue of the spatial identification using the grid pattern 12.
  • the device 1 can be used in a configuration other than that of figures 1 and 2, particularly in the configuration shown in figures 7 and 8.
  • the frame 20 has undergone the greatest possible translational movement forward with respect to the plate 10, the brackets 32 of the carriage 31 occupying the front ends of the guide slots 14 while, at the same time, the frame 20 is pivoted backward, by comparison with its 90° position of fi gures 1 and 2, with respect to the plate 10 by means of a corresponding setting of the wheels 35 of which another of the bores 35 2 than the one used for the configuration of figures 1 and 2 accepts the pawl 362.
  • the foot P and the leg J are positioned in such a way that the surgeon has good lateral access to the ankle C that is to be operated on, as clearly visible in figure 8, without being impeded by the components of the device 1.
  • the device 1 is remarkably adaptable in terms of the various conceivable routes via which the surgical operation on the ankle C can be tackled.
