Description

Technical Field

[0001] The utility model relates to the technical field of medical tools, in particular to a tissue repair bracket. Background Art

[0002] The arm repair bracket is composed of metal strips, bandages, etc., and is mostly an upper limb brace, including an upper limb abduction frame and an elbow joint brace, which mainly play a role in protection and fixation, and are mostly used after fracture or shoulder joint fixation surgery.

[0003] In the current arm repair bracket, there is a certain rotational damping between the bracket for fixing the upper arm and the bracket for fixing the lower arm, so that it can have simple activities. However, this method has certain defects. When the joint of the injured person is severely injured, especially in an emergency response, the activities performed are risky. It is necessary to adjust and always maintain a stable state to be safer and more suitable for the patient to wear. For this reason, we designed a tissue repair bracket. Summary of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A tissue repair bracket includes a chassis, a second connecting arm is fixed on the outer wall of the chassis, an adjusting mechanism is installed on the chassis, a first connecting arm is installed on the adjusting mechanism, and two symmetrical plastic plates are installed on both the first connecting arm and the second connecting arm;

[0007] The adjusting mechanism includes a rotating cylinder rotatably arranged on the chassis, a fixed block fixed on the chassis and located inside the rotating cylinder, a clamping member sleeved on the outer wall of the fixed block, a plurality of card slots are opened on the inner wall of the rotating cylinder, and the first connecting arm is fixed to the outer wall of the rotating cylinder.

[0008] As a further scheme of the utility model, a perforation for the bandage to pass through is opened on the plastic plate.

[0009] As a further scheme of the utility model, a notch is opened on the plastic plate, and the plastic plate is fixed to the corresponding first connecting arm and second connecting arm by screws at the notch. The arranged plastic plate is detachable, which is convenient for disassembly, replacement and cleaning.

[0010] As a further scheme of the utility model, the clamping member includes a fixing ring sleeved on the outer wall of the fixed block, and a limiting head adapted to the card slot is fixed on the outer wall of the fixing ring.

[0011] As a further solution of the utility model, a connecting plate is fixed to the top of the inner wall of the fixed ring, and a pull rod is fixed to the top of the connecting plate.

[0012] As a further solution of the utility model, two fixing bars are fixed to the top of the fixing block, the outer walls of the two fixing bars are fixed with the same top ring, a spring is fixed to the bottom of the top ring, and the bottom of the spring is fixed to the top of the fixed ring.

[0013] The beneficial effects of the utility model are as follows:

[0014] In the utility model: due to the adoption of the arranged chassis, first connecting arm, second connecting arm, plastic plate and adjusting mechanism, a bandage is threaded through the plastic plate for fixing the upper arm and lower arm of the injured person. By pulling the pull rod, the connecting plate drives the fixed ring, so that the limiting head disengages from the clamping groove, the spring is compressed, the fixed ring disengages from the rotating cylinder, the limit is released, and the rotating cylinder can rotate and adjust. After adjustment, the pull rod is released, and under the action of the spring, the fixed ring moves downward, and the limiting head penetrates into the clamping groove to limit the rotating cylinder and keep it stable, effectively solving the problems raised in the background technology, and further realizing fixation after angle adjustment, which is convenient and practical, and supports the arm joint after maintaining a relatively stable angle, contributing to the repair of the injured tissue and avoiding secondary injuries caused by the emergency reaction.

[0022] Referring to Figures 1 - 4 , a tissue repair stent includes a chassis (1). A second connecting arm (4) is fixed to the outer wall of the chassis (1). An adjusting mechanism (5) is installed on the chassis (1). A first connecting arm (2) is installed on the adjusting mechanism (5). Two symmetric plastic plates (3) are installed on both the first connecting arm (2) and the second connecting arm (4).

[0023] The adjusting mechanism (5) includes a rotating cylinder (7) rotatably arranged on the chassis (1). A fixed block (12) is fixed on the chassis (1) and located inside the rotating cylinder (7). A clamping member is sleeved on the outer wall of the fixed block (12). A plurality of card slots (9) are opened on the inner wall of the rotating cylinder (7). The first connecting arm (2) is fixed to the outer wall of the rotating cylinder (7).

[0024] In this embodiment, a perforation (301) for a bandage to pass through is opened on the plastic plate (3).
