Tendon anti-adhesion membrane anastomat for strengthening tendon anastomosis stoma

Abstract

The invention relates to a tendon anti-adhesion membrane anastomat for strengthening tendon anastomosis stoma. The anastomat comprises an annular housing with an opening, a membrane body and an anchornail; the membrane body is a narrow strip of biomaterial membrane, and the membrane body is uniformly provided with a plurality of micropores; the membrane body is divided into a guiding section anda bonding section in the longitudinal direction thereof, and a plurality of anchor nails are distributed on the inner side surface of the bonding section, the anchor nail is provided with a barb, andthe integral structure of the anchor nail and the barb is made of biological materials; the membrane body is wound in the open annular housing; the guiding section of the membrane body is placed outside the open annular housing; both sides of the annular housing with an opening are devices and are provided with guide grooves guiding to both sides of the membrane body. The inner annular surface ofthe opening annular housing is hollowed to accommodate the position of the anchor nails. The structure is simple, can quickly match the tendon connection, meet the requirement of normal activity of tendon after the tendon rupture surgery, reduce the tension of the tendon anastomosis; patients can immediately exercise after surgery; the risk of tendon adhesion is reduced; the clinical operation effect is improved and secondary surgery is avoided.

Description

technical field [0001] The invention relates to a surgical medical material, in particular to a tendon anti-adhesion membrane stapler for strengthening the tendon anastomosis. Background technique [0002] Tendon rupture is a common clinical trauma. At present, the commonly used techniques in the clinical repair of tendon rupture at home and abroad are mainly various suture methods and direct suture, and external fixation for 3-4 weeks after suturing. The problems after the operation are: first, the anastomotic stoma is in a state of traction, which is not good for tendon healing. After the operation, it is generally necessary to be immobilized for 3-4 weeks before it can move. Second, tendon adhesions are prone to occur, and most patients have to implement tendon release surgery, which brings secondary trauma to the patient. [0003] In view of the above-mentioned deficiencies in repairing tendon injuries with surgical sutures, the usual method is to wrap the tendon with a...

Problems solved by technology

At present, the commonly used techniques in the clinical repair of tendon rupture at home and abroad are mainly various suture methods and direct suture, and external fixation for 3-4 weeks after suturing. The problems after the operation are: first, the anastomotic stoma is in a state of traction, which is not good for tendon healing. After the operation, it is generally necessary to be immobilized for 3-4 weeks before moving; second, tendon adhesions are prone to occur, and most patients have to perform tendon release surgery, which brings secondary trauma to the patients

The disadvantage of the above invention is that the operation process is relatively complicated, the operation is relatively difficult, the fixation effect is unreliable, and the risk of tendon adhesion at the suture site is still relatively high

However, the two inventions directly use anchors to compress and fix the tendon, and the ratchet can only be locked in one direction and cannot be adjusted, so it has an oppressive effect on the tendon, which is not conducive to the endogenous healing of the tendon

At the same time, the bayonet may affect the movement of the tendon, and the tensile strength produced by the anchor compression is not very reliable, and its clinical application is still limited.

[0009] Therefore, in order to improve the effect of tendon anastomosis, it is necessary to study a material that can more effectively prevent tendon adhesion after surgery and enhance the tensile resistance of the anastomosis. The device completely solves the problem of tendon adhesion
