Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a tendon braider support device and a braiding method thereof. BACKGROUND

[0002] Human tendons are long, soft tissues. Due to the difficulty in positioning during tendon reconstruction surgery, the two ends of the tendon need to be sutured before the surgery. The traditional suture method is manual weaving, but manual weaving not only takes a long time, but also increases the risk of tendon infection.

[0003] In order to solve the above technical problems, at present, the tendon braider is mainly used to replace manual weaving. The commonly used tendon braider mainly consists of a first clamping plate, a second clamping plate and a limiting strip. For example, a utility model patent with the patent number CN213821889U and the name of a suture-free tendon fixing braider, and an invention patent with the patent number CN116115285A and the name of a tendon braider with a quick switching suture set. In the above two patents, the first clamping plate and the second clamping plate are hinged together, and a tendon containing channel is formed between the first clamping plate and the second clamping plate. One end of the tendon containing channel has a clamping opening for fixing the end of the tendon. A plurality of grooves are arranged on the inner side surface of the first clamping plate and the inner side surface of the second clamping plate, respectively, and the grooves are parallel to each other and penetrate through the corresponding clamping plate. The extension direction of the groove is perpendicular to the rotation shaft of the first clamping plate. An elastic channel is formed between the two elastic stop plates on both sides of the groove. The two ends of the braiding belt cross through all the grooves, and the two free ends of the braiding belt are located at one end of the tendon containing channel close to the clamping opening.

[0004] The above structure can improve the working efficiency of tendon weaving and reduce the pollution risk of tendon. However, the tendon braider does not have a fixed support structure, which makes it difficult to weave the tendon with the connecting line. Moreover, since the tendon with the connecting line needs to be woven in a reciprocating staggered manner, it is easy to cause deviation and stagger, which affects the progress of the surgery.

[0005] Therefore, how to design a tendon braider that can efficiently weave the tendon with the connecting line without causing deviation and stagger is a problem that needs to be solved by those skilled in the art. SUMMARY

The connecting block (211) has a through hole (2111) arranged opposite to the connecting hole (132). The side of the connecting block (211) near the supporting body (13) has a limiting hole (2112) and an adjusting screw hole perpendicularly communicating with the limiting hole (2112). The connecting rod (212)... The limit block (213) is inserted into the through hole (2111) and the connecting hole (132) in sequence; the limit block (213) is the limiting end of the limit member (21) and is placed in the limiting hole (2112); the limit bolt (214) is screwed into the adjusting screw hole and its screwed end is rotatably connected to the limit block (213) to adjust the gap between the limit block (213) and the hole wall of the limiting hole (2112); the other end of the limit band (22) is inserted into the gap between the limit block (213) and the hole wall of the limiting hole (232).

7. A tendon braiding device support device according to claim 6, characterized in that, The limiting member (21) also includes a pin (215) and a return spring (216). The connecting block (211) is provided with a return hole that is perpendicular to the limiting hole (232). The return hole is located parallel to one side of the limiting hole (2112). The pin (215) is inserted into the return hole. The return spring (216) is sleeved on the outer periphery of the pin (215) and one end of the spring is fixed to the pin (215), and the other end of the spring is fixed to the limiting block (213).

8. A tendon braiding device support device according to claim 1, characterized in that, It also includes a winding post, which is fixed on the support frame (11).

9. A method for tendon weaving, characterized in that, Including the tendon braiding device support device according to any one of claims 1-8, the specific steps are as follows: S1. Before installing the limiting piece (21), first insert the connection between the first braided plate (3) and the second braided plate (4) into the insertion gap. S2. Install the limiting member (21), and then limit one end of the limiting band (22) to the end of the first braided plate (3) near the support frame (11), and limit the other end to the limiting end of the limiting member (21); S3. Take a clean tendon-wrapped connecting line (5), connect an embroidery needle to one end of it, pull the embroidery needle through the first perforation (31) near the support frame (11) and the corresponding limiting band (22), then align the two ends of the tendon-wrapped connecting line, and connect another embroidery needle to the other end. S4. The traction tendon wraps around the other end of the connecting thread, and drives the embroidery needle on it to first pass through the second perforation (41) which is misaligned with the first perforation (31) in the previous sequence, then bypass the first braiding plate (3) and the second braiding plate (4), and finally pass through the first perforation (31) which is adjacent to the first perforation (31) in the previous sequence. S5. Repeat S4 until all the first perforations (31) are passed through; S6. One end of the traction tendon winding connecting line (5) first passes around the first braided plate (3) and the second braided plate (4), and then drives the embroidery needle on it to pass through the second perforation (41) near the support frame (11), and finally cross-penetrates into the first perforation (31) that is misaligned with the second perforation (41) above. S7. Continue to pull one end of the tendon wrapping connecting line (5), first go around the first braiding plate (3) and the second braiding plate (4), then take the embroidery needle on it, pass through the second perforation (41) which is misaligned with the first perforation (31) above, and finally crosswise pass through the first perforation (31) which is misaligned with the second perforation (41) above. S8, repeat S7 until the last remaining first perforation (31); S9. First remove the limiting piece (21), and then remove the first braided plate (3), the second braided plate (4), the limiting band (22) and the tendon wrapping line from the support body (13).

10. A tendon weaving method according to claim 9, characterized in that, The tendon winding connecting line (5) passes through the two ends of the same first perforation (31) and passes through different positions of the limiting band (22).
