The device comprises arrangements (5) or means (2) able to cooperate with only some of the anchoring tabs in order, on the one hand, to keep them in a splayed position corresponding to their introduction into the bone part in question and, on the other hand, to permit said introduction in said splayed position.

Description

DEVICE SUPPORT FOR SURGICAL IMPLANT SHAPE MEMORY

The invention relates to the technical field of surgical implants with shape memory, particularly to equipment for storage and handling.

It is well known to the skilled use of orthopedic implants shape memory to reduce fractures or other requiring fixation. This is particularly true of the interphalangeal arthrodesis of the hand and foot. Among the different types of implants include the osteosynthesis staples bipod type or quad example and intramedullary implants. In addition, depending on the type of alloy used, there are the hot shape memory implants and cold shape memory implants. Generally, implants are forced stored in a carrier to maintain a form suitable for introduction into the bone parts or question (s).

For example, a bipod staple of the type known under the brand memoclip is subjected to an operation to maintain the parallel legs. The two legs of the staple are positioned in two parallel holes formed in the thickness of a polyethylene support for example. These provisions help maintain the two parallel legs of the staple during storage and transportation. This position parallel with the two legs corresponds to the shape of insertion of the staple. The entire holder with the clip is stored in the cold, the clip being removed with a suitable clamp for implantation. In a known manner, at body temperature, the legs of the clip are closed to set the compression osteosynthesis considered home.

This solution is not entirely satisfactory because the materials used are relatively massive and mostly require a surface contact with the moving parts of the implant. For example, in the case of a clip, as indicated above, the entire length of the legs is in contact in the bracket holes.

The same disadvantages are found in the case of a shape memory of the intramedullary implant type, for example of the type whose legs substantially form an X, and wherein the entire length of said legs is in contact in the hole of support.

Reference is made to Figure 1 which shows a clip for osteosynthesis positioned in a holder according to the prior art and to Figure 2 which shows an intramedullary implant positioned in a holder also considered according to the prior art. This results in several disadvantages.

The friction of the implant in its support, is significant, we can not exclude the risk of tearing of the material. Similarly, the importance of the contact surface in the support require to have a contact surface as smooth as possible, so it is hardly possible to use shape-memory implant whose legs have, for example, anchoring roughnesses.

is also observed at the time of removal of the implant from its support, it is not possible to maintain the moving parts (legs, for example) by an instrument or by bone. This can result in unwanted movements, especially when the implant is not enough cold, forbidding her pose, or at least making it particularly tricky.

The invention has set itself the aim of overcoming these drawbacks in a simple, safe, effective and efficient.

The problem to be solved by the invention is to maintain, in their insertion position, the moving parts of the orthopedic implant shape memory, for storage until its impingement on the patient with the ability to have more freedom at the implant profile.

To resolve this problem, it has been designed and developed a support device of a surgical implant with shape memory having anchoring tabs for its impaction in a bone portion. This device comprises arrangements or means able to cooperate with only part of the anchoring legs to maintain the stress in a spread position corresponding to their introduction into the bone part in question.

Given these characteristics, it follows that the supporting device enables the maintenance of the implant with a contact area as small as possible and at a specified location in order to allow to create, for example, anchoring roughnesses at lugs and leaving free areas for, for example, the establishment of a clamp for gripping and handling. Depending on the type of implant used, the invention relates to one or more media devices that can optionally be combined with a gripper for the manipulation of said implant.

Thus, different technical solutions are considered.

In the case of an implant in the form of a bipod or quad staple, the device comprises a gripping body having holding arrangements in parallel position of the staple legs, said fittings being shaped to cooperate substantially to the level of a connecting part of said tabs so as to not interfere with anchoring protrusions that may have legs.

In the case of an implant of the intramedullary type whose legs substantially form an X, the device is constituted for each of the transverse sides of the X, by a gripper assembly having arrangements adapted to grip part of the two legs on the same side considered transverse to maintain them in close position. The arrangements consist of a semi-open loop adapted to enclose a portion of the tabs having no anchoring roughnesses and adapted to leave a free intermediate zone for positioning a clip at the time of impaction.

The invention is described below in more detail using the figures of the accompanying drawings in which: - Figure 1 is a sectional view, in schematic, showing a holder according to the prior art in the case a staple shape memory fixation;

- Figure 2 is a sectional view, in schematic, showing an intramedullary implant shape memory positioned in a holder according to the prior art;

- Figure 3 is a perspective view of a known example of a shape memory implant constituting a quad clip;

- Figures 4 and 5 are perspective views showing an embodiment of the support device according to the invention, in the case of a shape-memory implant of the type shown in Figure 3;

- Figure 6 is a perspective view of a shape memory of the intramedullary implant type and whose legs form a substantially X;

- Figure 7 is a perspective view showing one embodiment of the support device, in the case of an implant of the type shown in Figure 6, to keep it positioned in a shape corresponding to its introduction; - Figures 8 to 15 show the use of the support device illustrated in Figure 7, for insertion into the bone of the intramedullary implant shape memory shown in Figure 6.

As indicated, the support device of the invention finds application to any type of orthopedic implant shape memory, particularly in the case of staples osteosynthesis (Figure 3) and intramedullary implant (Figure 5). By shape memory means any material deformable by elasticity effect in view of the nature of the material or by temperature change (rise or fall).

Regardless of its embodiment, the orthopedic implant shape memory, designated as a whole by (I), includes anchoring legs (P) for its impaction in the bone parts or considered.

According to a basic feature of the invention, the support device comprises means adapted to cooperate with a part only of the anchor plates (P), to maintain the stresses, according to a spacing position corresponding to their introduction into or the relevant parts.

Figure 3 shows a staple bone shape memory of the type quad. In a perfectly known manner, this type of clip (1) comprises four legs (Ia), (Ib), (Ic), (Id) joined by a middle portion (le) of any shape. Different tabs (Ia), (Ib), (Ic), (Id) can be approximated in pairs, under the effect of the elasticity of the shape-memory alloy used and under the effect of the temperature rise, according to an arrow (F) and (Fl). In this case, the support device according to the invention comprises a grip body (2) having at one of its ends, holding arrangements in parallel position different tabs (Ia), (Ib), ( Ic), (Id). For example, as shown in Figures 4 and 5, the base of the gripping body (2) has two parallel wings (2a) and (2b) which delimit an opening inverted U (2c). After positioning of the body (2), the two wings (2a) and (2b) are arranged between the internal facing faces of the legs (Ia) and (Ic) on the one hand, and (Ib) and (Id), secondly, preventing said lugs to move closer according to the arrow (Fl). In other words, the wings (2a) and (2b) hold in position parallel legs (Ia) and (Ic) and (Ib) and (Id) corresponding to the insertion position.

Importantly, the wings (2a) and (2b) co-operate on a reduced surface area (If) of the legs thereby forming anchoring roughnesses (Ig).

In the case where the tabs (Ia) and (Ib) on the one hand, and (Ic) and (Id), on the other hand, are shaped to approximate naturally under the shape memory effect depending on the arrows (F), an additional tab

(3) can be inserted between the internal facing faces of the legs (la), (Ib) and

(Ic), (Id) (Figures 4 and 5).

In this exemplary embodiment, the support device in the form of a gripping body (2), obviously allows to grasp the staple to its impaction.

6 shows a shape memory intramedullary implant of the type (4) whose legs (4a), (4b), (4c) and (4d) substantially form an X. For this type of implant, the support device the invention comprises two substantially identical assemblies (El) and (E2) each cooperating with the transverse sides of the X, that is to say with the lugs (4a) and (4b), on the one hand, and legs (4c) and (4d) on the other hand. Each of the gripper assemblies (El) and (E2) has arrangements capable of gripping a portion of two legs (4a) and (4b), on the one hand, and the two legs (4c) and (4d) on the other hand, so as to hold them in close position corresponding to their introduction form (Figure 7). In particular, approximation of arrangements consist of a semi-open loop (5) capable of clamping, on a small area, a portion (4e) of the tabs having no anchoring roughnesses (4f). Each loop (5) is extended, on both sides, by legs (5a) and (5b) shaped on their free end to form an open ring (5c), (5d) adapted to act elastically on said loop . Obviously, these form loops fittings should not be limiting.

As shown in Figure 7, after positioning of the grippers assemblies (El) and (E2), on either side of the implant (4), the loops (5) maintain close the lugs (4a) and ( 4b), on the one hand, and (4c) and (4d) on the other, and leave open a free intermediate zone for positioning a gripper (6) at the moment of impaction of the implant (4) . Reference is made to Figures 8 to 15 which show the main steps for the introduction of the implant (4) in the two bones (01) and (02), for example.

In Figure 8, the clamp (6) is arranged on the side of the legs (4c) and (4d) held closed by the corresponding loop (5).

The gripper assembly (EI) is then removed, the legs (4c) and (4d) being kept closed by the clamp (6) (Figure 9). It is then possible to introduce, halfway, the implant (4) in the bone (01) (Figure 10). It is observed that the legs (4c) and (4d) remain in the closed position by the bone (01), while the legs (4a) and (4b) remain closed by the loop (5) of the gripper assembly (E2 ). The clamp (6) is then moved to the free zone which appears on the side of the legs (4a) and (4b) (Figure 11). It is then possible to withdraw the gripper assembly (E2), since the lugs (4a) and (4b) remain closed by the clamp (6) (Figure 12).

The operator may then engage the bone (02) halfway on the legs (4a) and (4b) that remain closed by the clip (6), noting that the bone (02) took relay (Figure 13).

He then simply remove the clamp (6) and end to engage the bone (02) on the implant (4) (Figure 14), the limbs (4a), (4b) and (4c) being then able for moving apart under the shape memory effect (temperature rise) or superelasticity effect.

It therefore appears that the support device according to the invention makes it possible, in a reliable and simple manner, the actual maintenance of shape memory implants since the device is removed when the bone or gripper has taken over to ensure such holding.

It is also recalled that the support device interacts with only a reduced coverage area of ​​the implant thereby have notched tabs to improve the anchoring in the bone.

The advantages are apparent from the description.
