AI Technical Summary
In traumatic orthopedic surgery, when the distal tibial and distal ulnar and radial joint separation are damaged, the existing fixation methods are too rigid or underpressurized, making it difficult to achieve appropriate fixation effects, increasing the risk of internal fixation breakage.
A two-point one-line pressing fixing system is designed, using titanium cable as the main cable, combining the fixing device of the tail end and the head end, and stably fixing the distal tibial and radial ulnar joints through pressurization and clamping fixing forceps.
The system can provide appropriate lateral pressure to achieve elastic fixation effect, reduce the risk of internal fixation caused by stress, and be closer to the original ligament fixation situation, which is conducive to the recovery of fractures.

Abstract
Description
Technical Field
[0001] Orthopedic medical device field. Background Art
[0002] In trauma orthopedic surgery, when the distal tibiofibular joint is separated or the distal radioulnar joint is separated and injured, the fixation method is single, or too rigid, or the pressure is insufficient. The present invention designs a two-point pressurized fixation titanium cable system for pressurized fixation of the distal tibiofibular joint and the distal radioulnar joint. At the same time, the cable properties of the titanium cable can also produce an elastic fixation effect under the condition of providing sufficient lateral pressure, which is closer to the original ligament fixation, more conducive to recovery, and reduces the situation of internal fixation fracture due to stress. Summary of the invention
[0003] The present invention discloses a two-point-one-line pressurized fixation system, wherein the main body is composed of a titanium cable (1) as a "line", a tail end fixing device (2), and a head end fixing device (3) as "two points" connected in series, and the three are connected, pressurized, and fixed to form a pressurized fixation effect. (Note: Since this fixation system is used for medical treatment, the cable is taken as a titanium cable, and other medical material cables can be used).
[0004] Description of the drawings: Figure 1 This is a schematic diagram of the overall connection of the fixing system. Figure 2 It is a cross-sectional view of the tail end fixing device (2). Figure 3 This is a cross-sectional view of the head end fixing device (3). Figure 4 The diagram is a schematic diagram of the route of the titanium cable (1) passing through the head end fixing device (3) and the clamping area of the clamping clamp head (11) of the clamping fixing clamp (13). Figure 5 It is a schematic diagram of the working sleeve (12). Figure 6 It is a schematic diagram of the clamping and fixing forceps (13). Figure 7 It is a schematic diagram of the pressure clamp (14). Figure 8 FIG. 1 is a schematic diagram of the titanium cable (1) as a whole, wherein the bend in the figure indicates the extension of the cable.
[0005] Detailed description of the fixing system composition, connection and use method in the attached drawings: After the head end (17) of the titanium cable (1) passes through the hollow (5) of the tail end fixing device (2), the tail end (4) is clamped on the tail end fixing device (2), and the head end (17) passes through the distal tibiofibular joint or the distal radioulnar joint to be fixed through the working sleeve (12), passes through the hollow (5) of the head end fixing device (3) on the opposite side, and then passes through the hollow tube wall (9) of the head end fixing device along the titanium cable passing direction (10) and then passes through the titanium cable cutting area (8). The head end (17) of the titanium cable (1) first passes through the titanium cable passing hole (15) of the clamp head at one end of the pressure clamp (14) without the fixing bolt (16), and then passes through the titanium cable passing hole (15) of the clamp head at the other end with the fixing bolt (16), and the titanium cable passing hole (15) is tightened to fix the titanium cable (1). The tail end of the closed pressure clamp (14) is used to exert pressure on the head end of the clamp. After the pressure is applied, the clamp head (11) of the clamp fixing clamp (13) is used to fit the hollow tube wall (9) in the clamp fixing area (7) of the head end fixing device (3). The pressure is applied to deform the hollow tube wall (9) to clamp and fix the titanium cable (1). Then, a universal metal scissor is used to cut the titanium cable (1) in the titanium cable cutting area (8). The cut head end (17) is discarded, and the pressure fixation is completed. When the titanium cable system is removed, it is cut in the titanium cable removal area (6) of the head end fixing device (3). The head end fixing device (3) is removed in sequence, and the titanium cable (1) and the tail end fixing device (2) are removed on the opposite side.
[0006] Main structure: The titanium cable (1), the tail end fixing device (2), and the head end fixing device (3) are made of titanium, titanium alloy, or other medical materials that can be placed in the body for medical purposes and meet the corresponding strength requirements. When manufacturing the titanium cable (1), it can be designed to be 5% smaller than the passage and pipe diameter thereof, such as the working sleeve (12), the tail end fixing device (2), the head end fixing device (3), etc., as a margin to facilitate the passage of the titanium cable (1).
[0007] The working sleeve (12), the pressure forceps (14), and the clamping and fixing forceps (13) can be made of any existing medical metal with sufficient strength.
