Description
Technical Field
The invention relates to the field of medical equipment, in particular to a meniscus suture instrument.
Background
The meniscus is a layer of fibrocartilage between the femur and tibia of the knee joint, belongs to the necessary structure of the knee joint, and plays an important role in maintaining joint function. Meniscus injury is a common athletic injury in orthopaedics that can lead to pain in walking or exercising and joint movement disorders, severely affecting the quality of life of the patient. Meniscus damage is mostly caused by torsional external forces, resulting in a meniscus tear, which can occur at the anterior, posterior and somatic corners of the meniscus. Because of poor meniscus blood circulation, the damaged meniscus is not easy to heal by itself, and the torn meniscus can damage other structures of the knee joint, thereby causing traumatic arthritis. Conventional treatments are arthroscopic meniscectomy or partial excision, where a meniscectomy that preserves the morphology of the meniscus is the most desirable procedure for treating a meniscal injury.
Currently, a sleeve-line type meniscus suture instrument is adopted for meniscus suture, the operation is carried out under the cooperation of an arthroscope, and two methods are basically adopted for meniscus suture under the arthroscope: the external-to-internal and total internal suturing, and the external-to-internal suturing technique is suitable for barrel handle-shaped, longitudinal, oblique, horizontal and transverse tears of meniscus anterior corners and body parts. During operation, a meniscus puncture needle is adopted to penetrate through the inner side of a meniscus tear, a suture passes through the skin outside the joint, the joint capsule and the front corner of the meniscus, then penetrates through the inner side edge of the meniscus tear, pulls the suture into the joint, pulls the suture outside the joint through another meniscus puncture needle, and then knots and fixes the suture.
The suturing device used at present is a fast-fix suturing system produced by Shihui corporation, which is suitable for barrel handle-shaped and longitudinal tearing of the rear corner and body of meniscus. Two needles are required to be penetrated in the suture process, two suture anchors are placed on the outer edge of the meniscus, the torn meniscus is fixed by pulling a line for knotting, the suture process needs better operation skills, the suture indication is relatively narrow, the suture process is relatively complex, the suture needle is relatively thick, and the damage is relatively large when the meniscus tissue is penetrated.
The above-mentioned suture mode all adopts single needle to sew up, and the shortcoming is that the art needs to wear the needle many times and tie down on the meniscus, need set up the tip that the line knot was used for fixed suture on the meniscus, perhaps the tip was tied down when the suture was fixed and is formed the knot on the meniscus, and line knot and knot lead to the fact vice damage to the meniscus easily, and in order to make the suture can be used for a long time, corresponding line knot and knot are made for the material that the human body can not absorb, lead to the fact the foreign matter reaction of human body like this easily. Therefore, the prior suture technology and suture instruments have certain defects, and the surgical requirements cannot be met increasingly.
