Description

Anastomat for surgical wound suturing

Technical Field

The invention relates to the technical field of anastomats, in particular to an anastomat for surgical wound suturing.

Background

The skin anastomat is suitable for surface skin suture of human body wound and operation incision and patch fixation for abdominal wall hernia repair. The skin anastomat is similar to a stapler principle, has the advantages of simplicity in operation, high suturing speed, good healing of postoperative incisions and the like, is a first-choice medical instrument for replacing traditional manual surface skin suturing in medicine, and is widely applied to departments such as general surgery, obstetrics and orthopedics in hospitals and occasions such as field rescue.

At present in the clinical use of skin anastomat, when the doctor sews up patient's skin wound through skin anastomat, once press the staple board to push down and move the anastomotic nail and cooperate the anastomotic baffle that stretches out, make the skin that the wound both ends passed the wound both sides, and then make skin sew up, after pressing the staple board to accomplish to press the staple, press the staple board to lift up the in-process that the anastomotic baffle was withdrawed, can appear the anastomotic nail because uncertain factor leads to the crooked back of staple both sides and presses the staple board inner wall fully to contact, can drive the anastomotic nail when leading to pressing the staple board to lift up, can the patient wound is pulled apart, bleeding phenomenon. The existing common skin anastomat is disposable, after the anastomosis nail is used up, the anastomat cannot be reused due to the fact that the anastomosis nail cannot be replaced, and after the skin of a patient is sutured, the skin anastomat with the unused anastomosis nail cannot be locked, so that when medical staff collects medical equipment, a movable handle of the anastomat is touched by mistake, the anastomosis nail is shot by mistake, and injury is caused to people.
