Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an orthopedic reduction and fixation device. Background Technology

[0002] In the treatment of fractures, surgical methods are used to ensure alignment and stability of the fracture ends, employing either internal or external fixation. Regardless of the method used, traction, displacement, rotation, and compression of the fracture site are necessary—a process known as fracture reduction. Currently, reduction and fixation devices are commonly used in fracture reduction. These devices primarily consist of a telescopic rod, upper and lower rings or a frame, a locking mechanism, and bone pins. The upper and lower rings are connected by a single-ball-joint telescopic rod or a double-ball-joint telescopic rod, and then the locking mechanism and bone pins are installed on the upper and lower rings and the telescopic rod. However, the existing technology has the following problems:

[0003] Existing orthopedic reduction and fixation devices connect and fix the patient's fracture site using multiple ring plates. This requires multiple bolts to adjust the length between the ring plates, making the adjustment cumbersome. Furthermore, the ring plates are a one-piece structure, which is not conducive to adjusting the fracture site and affects the patient's recovery. Utility Model Content

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides an orthopedic reduction and fixation device, which uses the cooperation between a protective component, an adjusting arc plate and a fixation component. By adjusting the distance between the two fixators according to the length of the fractured limb of the patient, the adjusting arc plates on both sides are moved up and down along the protective component. Then, the fixed component is operated to connect and fix the adjusted adjusting arc plate to the protective component. This solves the problem that the existing orthopedic reduction and fixation devices use multiple ring plates to connect and fix the fracture site of the patient, and require multiple bolts to adjust the length between the ring plates, which makes the adjustment cumbersome. This invention achieves the beneficial effect of conveniently adjusting the length of the fixator.

[0016] 2. This utility model provides an orthopedic reduction and fixation device. It utilizes a protective component, an adjusting arc plate, and a fixator in conjunction. When the fixator is installed at the patient's fracture site, the fractured area can be directly fitted into the semi-circular support plate by opening the first and second semi-circular support plates directly. Bolts are then inserted through the fixation holes in the two plates, and the distance between the first and second semi-circular support plates can be adjusted by rotating the nuts. This solves the problem that a one-piece ring plate structure is not conducive to adjusting the fracture site and affects patient recovery. It achieves the beneficial effect of facilitating the opening and closing of the semi-circular support plates, making it easier to adjust the fracture site and improving the patient's recovery.

[0030] The working principle of this orthopedic reduction and fixation device will be explained in detail below.

[0031] like Figure 1-5As shown, during fracture surgery, when using this device to reduce the fracture site, firstly, the semi-circular support plate 41 is rotated outward along the rotating groove 420 via the connecting block 43, opening the gap between the semi-circular support plate 41 and the semi-circular support plate 42. The tail of the patient's fractured limb is then placed inside the lower semi-circular support plate 41 and the lower semi-circular support plate 42. Then, the lower semi-circular support plate 41 and the lower semi-circular support plate 42 are closed, and two fixing holes 440 are created using corresponding bolts 45. The nut 46 is then rotated along the bolts 45 to further fix the semi-circular support plate 41 and the lower semi-circular support plate 42 to the surface of the patient's limb. Then, according to the length of the patient's fractured limb, the adjusting arc plates 2 on both sides are moved up and down along the surface of the connecting arc plate 12 via the moving groove 201, thus fixing the upper fixator 4... Adjust to the appropriate position, then use the knob 31 to insert into the corresponding socket 203 and screw it into the threaded hole 120 for fixation. Then repeat the above steps to fix the upper fixator 4 to the head of the fractured limb. Then slide the two upper and lower screws 63 along the arc-shaped groove 501 to the appropriate angle. Put the anti-slip pad 64 on the screw 63. Then fix the nut 65 together with the anti-slip pad 64 to the surface of the connector 5 by rotating the nut 65 against the outer wall of the screw 63. Then insert the locking pin 61 through the pin hole of the locking pin seat 62 at one end. Then pass the locking pin 61 through the bones at both ends of the fracture. Then pass the pin tip of the locking pin 61 out through the pin hole of the locking pin seat 62 at the other end. Repeat the above steps to pass the remaining locking pins 61 through the bones at both ends of the fracture in a cross manner to fix them, thereby achieving bone reduction and fixation.
