Description

Technical Field

[0001] The invention relates to the technical field of osteotome guide plates, in particular to a straight tubular bone shortening osteotome guide plate. Background Art

[0002] In orthopedic surgery, the removal of lesions in long bones of the limbs often requires osteotomy of the long bones. The osteotomy operation is to fully expose the bone segments of the limb bone osteotomy plane, introduce a wire saw to perform osteotomy, and after the osteotomy is completed, the diseased long bone is moved out of the surgical field.

[0003] Currently, manual osteotomy relies solely on the doctor's experience and the close cooperation of the surgeon and his assistants' "eyes, brain, and hands". This can easily lead to non-parallel osteotomy and difficulty in operation. It also requires high technical skills from the surgeon and takes a long time to perform osteotomy, making it impossible to achieve homogeneity in osteotomy among different doctors. Because it is difficult to control the parallelism of the osteotomy manually, it can easily lead to reduction difficulties, rotation, and angular deformity. It is difficult to perform osteotomy and reduction in a straight line, and the osteotomy ends on both sides may have poor contact and delayed bone healing after osteotomy, or even non-healing. This may require repeated or multiple surgeries, increasing the patient's pain and medical expenses.

[0004] To this end, the present application proposes a straight tubular bone shortening osteotomy guide plate to solve the above-mentioned problems. Summary of the invention

[0005] The present invention provides a straight tubular bone shortening osteotome guide plate, which has the advantages of being less likely to be non-parallel after osteotomy and being relatively simple to subsequently reposition, thereby facilitating control of the length of osteotomy and solving the problems raised by the above-mentioned background technology.

[0006] The present invention provides the following technical solution: a straight tubular bone shortening osteotomy guide plate, comprising a straight tubular bone body and a guide plate body, wherein osteotomy groove 1 and osteotomy groove 2 are respectively provided on the top of the guide plate body, a through hole is provided through the top of the guide plate body, two insertion holes are provided through the top of the guide plate body, and an injection guide mechanism is provided on the inner wall of the guide plate body.

[0007] As a preferred technical solution of the present invention, the injection guide mechanism includes a slide groove, which is opened at the top position of the guide plate body, and the inner wall of the slide groove is symmetrically provided with two limit grooves, and the inner walls of the limit groove are respectively fixedly equipped with two positioning rods, and the outer edges of the positioning rods are slidably connected with moving bars, and the middle part of the moving bar is fixedly equipped with a positioning plate, and the middle part of the positioning plate is penetrated by a pinhole.

[0008] By adopting the above technical solution, the movable bar can slide stably on the inner wall of the limiting groove through the positioning rod, and then the position of the positioning plate and the needle hole can be adjusted at will, thereby facilitating improving the accuracy of the user injecting the Kirschner wire through the needle hole. When the Kirschner wire is fixed at the fracture position, it can effectively limit the movement of the fracture, thereby reducing the pain of the fracture, and is also beneficial to the healing of the fracture.

[0009] As a preferred technical solution of the present invention, movable holes are opened on the inner walls on both sides of the movable bar, the positioning rod is arranged at the inner wall position of the movable hole, the outer edge diameter of the positioning rod is adapted to the inner wall diameter of the movable hole, and the two sides of the movable bar are slidably connected to the inner wall positions of the two limit grooves.

[0010] By adopting the above technical solution, the outer edge diameter of the positioning rod is adapted to the inner wall diameter of the moving hole, so that the moving bar is restricted by the positioning rod when sliding, which can ensure the synchronization of both sides of the moving bar when sliding, and further ensure that it will not be arbitrarily shifted in position, thereby improving stability.

[0011] As a preferred technical solution of the present invention, the distance between osteotomy groove one and osteotomy groove two is 3 mm, the inner wall width of osteotomy groove one and osteotomy groove two is 1 mm, and osteotomy groove one and osteotomy groove two are arranged in parallel at 45 degrees.

[0012] By adopting the above technical solution, the osteotomy groove 1 and the osteotomy groove 2 are arranged parallel to each other at 45 degrees, so that the problem of non-parallelism is less likely to occur after osteotomy, and the subsequent reduction is relatively simple.

[0013] As a preferred technical solution of the present invention, the inner wall diameter of the through hole is 2 mm, and the inner wall diameter of the plug hole is 1.2 mm.

[0014] By adopting the above technical solution, through holes and sockets are used to make it possible to cooperate with steel nails to firmly fix the guide plate body and the straight tubular bone body to ensure that they will not fall off easily, thereby achieving a good positioning effect on the straight tubular bone body after osteotomy and facilitating recovery.

[0015] As a preferred technical solution of the present invention, the guide plate body is made of titanium alloy, and the length of the guide plate body is 40 mm.

[0016] By adopting the above technical solution, the guide plate body made of titanium alloy can be made easy to carry due to its light weight, and can be used for a long time in various environments, including acidic and alkaline environments without being damaged.

[0017] As a preferred technical solution of the present invention, the inner wall length of the slide groove is 10 mm, and the guide plate body is arranged at the outer edge of the straight tubular bone body.

[0018] By adopting the above technical solution, the guide plate body is arranged at the outer edge of the straight tubular bone body, so that the guide plate body can be used to position and guide the straight tubular bone body, thereby improving the healing period after osteotomy.

[0019] The present invention has the following beneficial effects:

[0020] 1. The straight tubular bone shortening osteotomy guide plate is arranged at 45 degrees parallel to the osteotomy groove 1 and the osteotomy groove 2, so that the problem of non-parallelism is not easy to occur after osteotomy, and the subsequent reduction is relatively simple, so that it is easy to control the length of the osteotomy, avoid the problems of easy dislocation, rotation, and angular deformity, and the guide plate body is compact in design, easy to carry and disinfect, and can be applied to osteotomy of hands, upper limbs, feet and lower limbs, more energy-saving, and has a wide range of applications. After osteotomy, ordinary steel plates can be fixed without the need for special steel plates, and the cost is low.

[0021] 2. The straight tubular bone shortening osteotomy guide plate can slide the moving bar until the needle hole is aligned with the injection position, and then the Kirschner wire needle can be passed through the needle hole to perform the injection operation on the straight tubular bone body. After the Kirschner wire is fixed at the fracture position, the movement of the fracture can be effectively restricted, thereby reducing the pain of the fracture, and it is also beneficial to the healing of the fracture. The needle hole can improve the accuracy of the Kirschner wire injection. BRIEF DESCRIPTION OF THE DRAWINGS
