Abstract

The invention discloses a skin stapler comprising a base, a stapling needle and a first drive mechanism. The base is provided with an arc needle slot therein, a first needle hole corresponding to one end of the arc needle slot and a second needle hole corresponding to the other end of the arc needle slot. The stapling needle is arc shaped; the stapling needle fitting the arc needle slot is fitted into the arc needle slot. The first drive mechanism is mounted on the base. In the initial state, the stapling needle is retracted into the base; during stapling, the ends of the first and second needle holes of the base compress two sides of a wound to be stapled; the first drive mechanism drives the stapling needle to move along the arc needle slot, so that the stapling needle can pass through the first needle hole into the skin, pass out of the skin and pass into the second through hole in order. The first drive mechanism drives the staling needle to move in an arc path so as to effect the reduction in secondary injury caused by the arc path to the outer skin tissues, knotting is automated, and stapling efficiency is higher.

Description

technical field [0001] The invention relates to a medical device for wound suturing. Background technique [0002] Epidermal suture is a common treatment method for surgeons. Its use is such as the epidermal suture of wounds, mostly after surgery. In addition, today’s minimally invasive surgery has its unique characteristics of small wounds, fast healing, and maximum protection of blood vessels and nerves. It has been widely popularized, but at this stage, doctors face many difficulties in epidermal suture: [0003] a) Secondary trauma caused by suturing [0004] Most of the suture needles used by doctors are arc-shaped, and most of them are about 210 degrees. The most accurate suture needles should be arc-shaped needles, but it is difficult to do it due to the limited control ability of human brain, nerves and muscles. [0005] For example: assuming that the needle length is 210 degrees, the needle-type suture arc of the suture needle in the epidermis is 120 degrees. Taki...
