Description

Technical Field

[0001] The present invention relates to the technical field of surgical instruments, and particularly to a multifunctional revision surgery tool system. Background Art

[0002] Total knee arthroplasty has developed for several decades in China. After a large number of primary patients, the number of patients requiring revision surgery is increasing day by day. Therefore, a set of fully functional and highly accurate revision surgery tools can improve the smoothness of the surgery, save surgical time, increase the success rate and surgical experience of artificial joint revision surgery, thereby reducing surgical risks and improving the patient's rehabilitation index.

[0003] After primary prosthesis replacement, due to unexpected trauma or long-term use of the patient, the primary prosthesis may become loose or bone defects may occur again, resulting in pain for the patient and further loss of walking function. This requires a prosthesis revision surgery, that is, removing the original prosthesis, reconstructing the bone interface, and accurately installing the revision prosthesis. Two points are very important during the revision prosthesis surgery: 1. Try to retain the original bone mass, reconstruct the bone interface, and ensure the fit between the revision prosthesis and the bone joint surface; 2. Accurately locate the relative position of the medullary cavity and the prosthesis joint surface to ensure the accuracy of the prosthesis placement to restore the joint line of force.

[0004] Among them, in knee joint revision surgery, there are more difficulties in the reconstruction of the femoral side. That is, it is necessary to ensure that the positioning rod is located in the middle of the medullary cavity to reconstruct the line of force, and at the same time ensure the maximum fit between the prosthesis and the bone joint surface. This requires surgical tools that can not only achieve accurate osteotomy but also perform accurate line of force and prosthesis eccentric positioning to ensure the successful progress of the surgery.

[0005] However, the existing knee joint revision surgery tools have certain defects:

[0006] a. In the existing revision surgery tools, osteotomy cannot be directly performed on the condyle trial mold. The osteotomy tool and the femoral condyle trial mold are separate. This often requires the doctor to first perform osteotomy on the bone interface and then perform condyle trial mold adaptation. When it is found that there is a deviation in the position of the condyle trial mold, it is often impossible to re-adjust the bone joint surface or require re-osteotomy; this will lead to inaccurate prosthesis installation position or increased osteotomy amount, increasing surgical risks.

[0007] b. In the existing surgical tools, the positioning of the medullary cavity and the revision prosthesis is often not performed on the condyle trial mold, but other positioning tools are used to determine the relative position, and then the doctor adjusts the relative installation position of the positioning rod and the condyle trial mold according to the values determined by the positioning tools. Due to the step-by-step operation, measurement deviation will occur. When the positioning rod and the condyle trial mold are assembled together and placed on the bone interface for reduction, there are often position deviations, and it is necessary to remove the intramedullary rod and the condyle trial mold and re-use the positioning tools for re-positioning, resulting in an extended surgical time or the line of force exceeding the planned range, increasing the risk of surgical failure.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] After the primary knee joint prosthesis replacement, due to unexpected trauma or long-term use of the patient, the primary prosthesis may become loose or bone defects may occur again, resulting in pain for the patient and further loss of walking function. This requires removing the original prosthesis, reconstructing the bone interface, and installing a revision prosthesis. This process is the revision surgery of the knee joint. In the existing knee joint revision surgery, the steps on the femoral side are to first reconstruct the bone interface, then install the condyle trial mold at the reconstructed bone interface, confirm the relationship between the condyle trial mold and the femoral alignment, as well as the relationship between the condyle trial mold and the distal femur, and finally remove the condyle trial mold and install the condyle prosthesis.

[0044] However, this surgical procedure has certain defects: in the prior art, doctors need to first perform osteotomy of the bone interface and then perform condyle trial mold fitting. When it is found that there is a deviation in the position of the condyle trial mold, osteotomy needs to be performed again, which may result in inaccurate installation position of the prosthesis or an increase in the osteotomy amount, increasing the surgical risk; furthermore, in the prior art, a positioning tool is used to determine the relationship between osteotomy and alignment. Doctors adjust the relative installation position of the alignment rod and the condyle trial mold according to the determined values. When the alignment rod and the condyle trial mold are assembled together and placed on the bone interface for reduction, deviations often occur. At this time, it is necessary to remove the alignment rod and the condyle trial mold and reposition them, which also increases the surgical risk.

[0045] Based on this, the present application considers solving the problems in the prior art by directly confirming the relative position between the alignment and the condyle trial mold on the condyle trial mold and directly confirming the osteotomy position on the condyle trial mold. Specifically, the present application provides an embodiment, specifically the best solution of a multifunctional revision surgery tool system, to cooperate with the new surgical method to achieve the technical effect of first installing the condyle trial mold and then reconstructing the bone interface, reducing the surgical risk.

[0046] Specifically, as Figure 1, this tool system includes a condyle test mold 1. The shape and structure of the main body of the condyle test mold 1 are the same as those in the traditional knee joint revision surgery technique. The condyle test mold 1 includes an intercondylar groove 14 and an osteotomy groove 15. When the condyle test mold 1 is installed on the distal femur, the intercondylar groove 14 exposes the intercondylar position of the distal femur. It also includes a columnar cylinder member 2. The columnar cylinder member 2 includes a through hole. The two ends of the through hole extend to the two end portions of the columnar cylinder member 2 respectively. The central axis of the through hole forms an angle with the central axis of the columnar cylinder member 2. This angle is preferably the angle between the femoral force line and the femoral mechanical axis. The connection between the condyle test mold 1 and the columnar cylinder member 2 is detachable. It further includes a column member 3. The column member 3 includes a force line through hole 31. The two ends of the force line through hole 31 extend to the two end portions of the column member 3 respectively. The force line through hole 31 is located at an eccentric position of the column member 3. When the column member 3 is placed in the through hole and an external force is applied to rotate the column member 3, the relative position between the columnar cylinder member 2 and the force line through hole 31 can be adjusted.

[0047] As Figure 2 , during the femoral side operation of knee joint revision surgery, first remove the original primary prosthesis of the patient, expose the original bone interface A on the femoral side, drive a force line rod 6 at the distal position of the bone interface A to determine the femoral force line. Then place the condyle test mold 1 at the bone interface A, and the force line rod 6 passes through the intercondylar groove 14 and is exposed outside the condyle test mold 1. Next, install the columnar cylinder member 2 on the condyle test mold 1, make the columnar cylinder member 2 fixedly connected to the condyle test mold 1, and at the same time make the through hole correspond to the intercondylar groove 14. The force line rod 6 passes through the through hole and is exposed outside the columnar cylinder member 2. Then place the column member 3 in the through hole, make the force line rod 6 pass through the force line through hole 31. At this time, the force line rod 6 is coaxial with the column member 3 and forms an angle with the through hole, that is, the installation force line of the condyle test mold 1 is guaranteed at this time. Only need to adjust the relative position between the condyle test mold 1 and the bone interface A to make the condyle test mold 1 fit the bone interface A to the greatest extent. Specifically, it is necessary to manually rotate the column member 3. Since the force line rod 6 placed in the force line through hole 31 is fixed and the force line through hole 31 is located at an eccentric position of the column member 3, the column member 3 has an interference effect on the through hole of the columnar cylinder member 2, so the column member 3 will drive the columnar cylinder member 2 to rotate, thereby driving the condyle test mold 1 to adjust its position relative to the bone interface A. Finally, remove the column member 3 and the columnar cylinder member 2, fix the condyle test mold 1, and then use an osteotome to perform osteotomy at the osteotomy groove 15.

[0048] Performing the osteotomy operation after first fixing the condyle test mold 1 in this way can avoid measurement errors, ensure that the force line is consistent with the surgical plan, and at the same time ensure that the reconstructed bone interface corresponds precisely to the position of the femoral condyle revision prosthesis determined, making the surgery smoother, reducing the surgical operation time, and reducing the surgical risk.

[0049] Furthermore, the structure of the column member 3 is specifically: As Figure 3, including a positioning part 32 which is used to extend into the through hole. The positioning part 32 is preferably a cylindrical structure, and the outer diameter of the positioning part 32 is adaptively matched with the inner diameter of the through hole, so that the positioning part 32 can just be placed into the through hole; it also includes a handle part 33 which is connected to or integrally formed with the positioning part 32 and is used for convenient grasping. In this embodiment, the handle part 33 is preferably also a cylindrical structure and is preferably integrally formed with the positioning part 32; it further includes a flange 34 which is connected to or integrally formed with the positioning part 32 / handle part 33. The flange 34 is used to form a blocking effect on the end of the cylinder part 2 to prevent the column part 3 from axially moving in the cylinder part 2. In this embodiment, the flange 34 is preferably integrally formed with the positioning part 32 and the handle part 33; one end of the force line through hole 31 extends to the end of the positioning part 32, and the other end extends to the end of the handle part 33, that is, the force line through hole 31 penetrates the column part 3.

[0050] Furthermore, in order to adapt to the application scenarios of the left and right legs, such as Figure 4 , the tool system is provided with through holes including a left through hole 21 and a right through hole 22. The central axes of both the left through hole 21 and the right through hole 22 form an angle with the central axis of the cylinder part 2, so that the cylinder part 2 can be commonly used on the left and right legs. At the same time, the left through hole 21 and the right through hole 22 overlap with each other. The overlapping left through hole 21 and right through hole 22 share space, so that the volume of the cylinder part 2 can be kept small, thus reducing surgical tools and lowering costs;

[0051] Furthermore, since there is an angle between the column part 3 and the cylinder part 2 after the column part 3 is placed into the cylinder part 2, and in order to have a relatively stable relationship between the column part 3 and the cylinder part 2, the flange 34 needs to fit with the end of the cylinder part 2. Based on this, such as Figure 4 , the cylinder part 2 is provided with a left avoidance surface 26 and a right avoidance surface 27 arranged at one end of it. The left avoidance surface 26 or the right avoidance surface 27 is correspondingly fitted with the flange 34. The left through hole 21 extends to the left avoidance surface 26, and the right through hole 22 extends to the right avoidance surface 27.

[0052] Furthermore, such as Figures 3 - 4 , in order to record the relative position between the condylar trial mold 1 and the force line rod 6 for facilitating the placement of the revision prosthesis subsequently, the cylinder part 2 is provided with an indicating arrow 23 which is located on the outer wall of the cylinder part 2. The column part 3 is provided with a scale 35 which is located on the flange 34. The scale 35 corresponds to the indicating arrow 23 and is used to indicate the relative position between the condylar trial mold 1 and the force line. Preferably, the indicating arrow 23 includes a left indicating arrow and a right indicating arrow, which are respectively used to record the situations of the left and right legs.

[0053] Furthermore, such as Figure 4, the cylinder member 2 further includes a direction identifier 24, which includes a left direction identifier and a right direction identifier for indicating the left and right directions to facilitate the operation of the doctor.

[0054] Furthermore, the connection manner between the cylinder member 2 and the condyle trial mold 1 is as follows: Figures 4 - 5 , the cylinder member 2 includes a first hanging ear 25, which is arranged outside the cylinder member 2 and is connected to or integrally formed with the cylinder member 2. Preferably, there are two first hanging ears 25, which are cylinder structures with one end closed and are integrally formed with the cylinder member 2; the condyle trial mold 1 includes a threaded hole 16, which is opened on the condyle trial mold 1. Preferably, there are recessed steps 18 on both sides of the condyle trial mold 1 close to the intercondylar groove 14, and there are two threaded holes 16, which are respectively opened on the two recessed steps 18; the tool system further includes two screws 4, and the first hanging ear 25 and the threaded hole 16 are connected by the screws 4. Among them, the screws 4 are preferably countersunk screws. When connecting the first hanging ear 25 and the threaded hole 16, the head of the screw 4 sinks into the first hanging ear 25.

[0055] Furthermore, as Figure 5 , the condyle trial mold 1 further includes a plurality of fixing holes 17, which are respectively distributed on the anterior condyle segment trial mold 11 and / or the distal segment trial mold 12 for inserting fixing nails 7 to fix the condyle trial mold 1. Preferably, there are three fixing holes 17 distributed at the edge of the anterior condyle segment trial mold 11, and there are two fixing holes 17 distributed at the edge of the distal segment trial mold 12, so that the condyle trial mold 1 can be stably connected to the bone interface A, as Figure 7 That is, it shows a schematic diagram of fixing the condyle trial mold 1 at the bone interface A after removing the cylinder member 2 and the column member 3.

[0056] Furthermore, as Figure 5 , the condyle trial mold 1 includes an anterior condyle segment trial mold 11, a distal segment trial mold 12, and a posterior condyle segment trial mold 13, and the anterior condyle segment trial mold 11, the distal segment trial mold 12, and the posterior condyle segment trial mold 13 are integrally formed.

[0057] Furthermore, as Figures 5 - 6, there are several osteotomy grooves 15, which are respectively distributed on the anterior condyle segment test mold 11 and / or the distal segment test mold 12 and / or the posterior condyle segment test mold 13, and each osteotomy groove 15 extends to communicate with the outer edge of the condyle test mold 1 to facilitate the entry of the saw blade; preferably, two first osteotomy grooves 151 are provided on both the inner and outer sides of the anterior condyle segment test mold 11, and the first osteotomy groove 115 extends from the anterior condyle segment test mold 11 to the posterior condyle segment test mold 13 for osteotomy of the distal end of the bone interface A. Among them, the first osteotomy grooves 151 on the same side of the anterior condyle segment test mold 11 all include a 5-mm osteotomy groove and a 10-mm osteotomy groove, that is, the vertical distance from the first osteotomy groove 151 to the distal segment test mold 12 is 5 mm or 10 mm. Preferably, two second osteotomy grooves 152 are provided on both the inner and outer sides of the distal segment test mold 12, and the second osteotomy grooves 152 are used for osteotomy of the posterior condyle of the bone interface A. Among them, the second osteotomy grooves 152 on the same side of the distal segment test mold 12 all include a 5-mm osteotomy groove and a 10-mm osteotomy groove, that is, the vertical distance from the second osteotomy groove 152 to the posterior condyle segment test mold 13 is 5 mm or 10 mm. During the osteotomy process, different osteotomy grooves 15 can be selected according to the bone defect situation to reconstruct the bone interface.

[0058] Further, the intercondylar groove 14 can also be used as an osteotomy guiding groove, and intercondylar osteotomy is performed along the inner wall of the intercondylar groove 14 to fix the final placement position of the revision prosthesis; when performing osteotomy along the intercondylar groove 14, since the side wall of the intercondylar groove 14 near the anterior condyle segment test mold 11 is relatively thin and cannot provide a good guiding effect on the saw blade, therefore, as Figure 5 , the condyle test mold 1 is further provided with a connection hole 19, and the connection hole 19 specifically includes an oval through hole and circular through holes on both sides of the oval through hole. The connection hole 19 is used to connect with the columnar member on the guiding block, so that the guiding block is connected to the condyle test mold 1. Thus, intercondylar osteotomy can be performed along the guiding block to provide a guiding effect on the saw blade, as Figure 8 which shows a schematic diagram of the completion of intercondylar osteotomy at the bone interface A.

[0059] Further, in order to restore the overall shape of the revision femoral condyle prosthesis and facilitate the subsequent installation of the revision femoral condyle prosthesis, as Figure 9 , this tool system further includes an intercondylar test mold 5, where the intercondylar test mold 5 specifically includes an intercondylar test mold main body 51, and the intercondylar test mold main body 51 is a columnar structure, which is the part implanted into the bone; it also includes a test mold supplement 52, the test mold supplement 52 is correspondingly attached to the intercondylar groove 14, the test mold supplement 52 is integrally formed with the intercondylar test mold main body 51, and the test mold supplement 52 and the condyle test mold 1 can be spliced to form the complete shape of the revision femoral condyle prosthesis.

[0060] Further, the connection method between the intercondylar test mold 5 and the condyle test mold 1 is: as Figure 5 、 9, the intercondylar trial mold 5 includes a second hanging ear 53. The second hanging ear 53 corresponds to the threaded hole 16, and the second hanging ear 53 and the threaded hole 16 are also connected by screws 4. The concave step 18 corresponds to and fits with the second hanging ear 53, making the splicing of the intercondylar trial mold 5 and the condylar trial mold 1 complete and smooth.
