Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fracture instruments, in particular to a surgical guide plate for percutaneous fixation of wrist fractures. Background Art
[0002] The guide plate used in percutaneous fixation surgery for wrist fractures is a medical device used to realign and stabilize broken wrist fractures. The guide plate is usually made of metal materials (such as titanium alloy) and has a special shape and structure that can adapt to the anatomical characteristics of the wrist joint. During the operation, the doctor will place the guide plate near the fracture through a small incision, and then use screws or other fixation devices to fix the guide plate to the bones on both sides of the fracture. This percutaneous fixation surgical method can reduce surgical trauma, shorten the recovery period, provide better fracture stability, and promote fracture healing.
[0003] Currently available surgical guides may have some limitations in position adjustment and cannot fully adapt to people with various arm lengths. This is mainly because existing surgical guides are basically fixed in length and shape and cannot be adjusted according to the specific conditions of the patients. First, due to certain differences in people's arm lengths, the same type of fractures may have different distributions in different patients. Therefore, the length of the surgical guide may not be able to fully match the patient's wrist fracture, resulting in increased surgical difficulties. Secondly, the shape of the surgical guide is also fixed and cannot flexibly adapt to the anatomical differences of different patients, thereby affecting the accuracy and effectiveness of the operation. For this reason, we propose a surgical guide for percutaneous fixation of wrist fractures. Utility Model Content

The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.
[0023] Embodiment:
[0024] like Figure 1-6 As shown, a surgical guide for percutaneous fixation of wrist fractures includes a surgical plate frame 1, a head fixing plate 2 is arranged on the surgical plate frame 1, arm supports 4 are arranged on both sides of the surgical plate frame 1, a wrist fixing plate assembly 3 is arranged on the arm support 4, a first adjustment assembly 5 is arranged on the wrist fixing plate assembly 3 and the arm support 4, a second adjustment assembly 6 is also arranged on the wrist fixing plate assembly 3, and a leg fixing frame 7 is arranged at the bottom end of the surgical plate frame 1, wherein the wrist fixing plate assembly 3 includes a first slide groove 34 opened on the arm support 4, a first slider 33 slidably connected to the first slide groove 34, a slider 32 fixed on the outer wall of the first slider 33, a fixing plate 31 fixed on the slider 32 and provided with the second adjustment assembly 6 inside, and a support plate 35 connected to the second adjustment assembly 6.
[0025] The first adjustment assembly 5 includes a first fixing seat 51 inserted into the slide plate 32 and connected to the first slide block 33, a first convex plate 52 fixed to the first fixing seat 51, a groove 53 provided in the first convex plate 52, a rotating shaft 54 connected to the inner wall of the groove 53, a clamping rod 55 rotatably connected to the outer wall of the rotating shaft 54, a second fixing seat 57 fixed to the outer wall of the arm support 4, a second convex plate 56 fixed to the second fixing seat 57, and a threaded sleeve 58 connected to the clamping rod 55;
[0026] When the staff needs to adjust the position of the fixing plate 31, they only need to screw the threaded sleeve 58 outwardly so that the threaded sleeve 58 moves outward on the locking rod 55 and releases the contact with the outer wall of the second convex plate 56. At this time, the locking rod 55 is rotated upward so that the locking rod 55 rotates upward on the rotating shaft 54 and finally separates from the second convex plate 56. After all the locking rods 55 are rotated upward, the slide plate 32 can be pushed so that the slide plate 32 slides in the first sliding groove 34 through the first sliding block 33. After sliding to a suitable position, the locking rod 55 is rotated so that the locking rod 55 is engaged with the corresponding second convex plate 56. The first convex plate 52 and the second convex plate 56 are both provided with a groove 53, and the shape of the groove 53 is set to be U-shaped. Then the threaded sleeve 58 is rotated and tightened. The outer end of the locking rod 55 is provided with an external thread, and the threaded sleeve 58 is threadedly connected to the outer end of the locking rod 55. The diameter of the threaded sleeve 58 is set to be larger than the width of the groove 53, so as to ensure that the threaded sleeve 58 and the outer wall of the second convex plate 56 are fitted to form a limit.
[0027] The support plates 35 are symmetrically arranged in two groups, and two groups of second adjustment components 6 are opened in the fixed plate 31 corresponding to the support plates 35. The second adjustment components 6 include an active cavity 61 opened in the upper part of the fixed plate 31, a threaded rod 62 rotatably connected in the active cavity 61 and penetrating the outer wall of the fixed plate 31, a rotating shaft 63 fixed on the outer end of the threaded rod 62, a nut block 64 connected to the threaded rod 62 and fixed with the support plate 35, a second slide groove 66 opened in the lower part of the fixed plate 31, and a second slider 65 slidably connected to the second slide groove 66 and fixed to the support plate 35;
[0028] When the staff needs to adjust the spacing between the two groups of support plates 35, they only need to rotate the rotating shaft 63, and the rotating shaft 63 drives the threaded rod 62 to rotate in the movable cavity 61, and the threaded rod 62 drives the nut block 64 to move on the threaded rod 62, and the nut block 64 drives the support plate 35 fixed thereto to move, and the length of the movable cavity 61 is set equal to the length of the second slide groove 66, and the second slide groove 66 and the movable cavity 61 are symmetrically arranged, and the bottom end of the support plate 35 slides synchronously in the second slide groove 66 through the second slider 65, and the spacing between the support plates 35 can be adjusted.
[0029] Here’s how it works:
[0030] 1. When the position of the wrist fixing plate 31 needs to be adjusted, the staff member screws the threaded sleeve 58 to move it away from the second convex plate 56, and then the staff member rotates the engaging rod 55 to separate it from the second convex plate 56, so that the slide plate 32 can slide. After the staff member slides the slide plate 32 to a suitable position, the engaging rod 55 is rotated to engage with the second convex plate 56. By tightening the threaded sleeve 58, the connection between the engaging rod 55 and the second convex plate 56 is ensured to be tight.
[0031] 2. The spacing between the two sets of support plates 35 is adjusted by the second adjustment component 6. The staff rotates the rotating shaft 63, causing the threaded rod 62 to rotate in the movable cavity 61. The threaded rod 62 drives the nut block 64 to move thereon, thereby driving the support plate 35 fixed on the nut block 64 to move together. The length of the movable cavity 61 is equal to the length of the second slide groove 66, and they are symmetrically arranged. The bottom end of the support plate 35 slides synchronously in the second slide groove 66 through the second slider 65, and the adjustment can be completed by adjusting the spacing between the two sets of support plates 35.
[0032] Through the above steps, the staff can flexibly adjust the various components of the surgical guide according to the needs of the patient to ensure the patient's comfort and stability during the operation.
[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.
