Abstract

The invention discloses a linear suturing and excising device, comprising a body, a staple cartridge rack, a knife pushing rod and an excising knife, wherein a staple cartridge is arranged on the staple cartridge rack, a cocking block is arranged in the staple cartridge, the knife pushing rod pushes the cocking block to move, the staple cartridge rack is provided with a boss playing a safety effect, the far end of the excising knife is provided with an elastic sheet which is fixedly connected with a stop dog, and the cocking block drives one side of the elastic sheet to move for enabling the stop dog to generate displacement vertical to the moving direction of the cocking block. The linear suturing and excising device has the beneficial effects that doctors are effectively prevented from performing the next operation under the condition that a cocked staple cartridge is not replaced, so that occurrence of medical negligence is avoided, and the structure is simple and effective.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a linear suturing and cutting device with a secondary safety mechanism, which belongs to the technical field of medical instruments. Background technique [0002] Surgical linear suture cutting devices are widely used for wound suturing, internal tissue suturing and cutting. With the development of surgery, minimally invasive surgery has become more and more popular. In a broad sense, surgery that can reduce trauma is called minimally invasive surgery; in a narrow sense, minimally invasive surgery refers to surgery performed under an endoscope. The operation carried out under the endoscope generally only needs to open several small holes on the patient's body, and excision, suturing tissue and auxiliary instruments are inserted into the patient's body through the small holes for surgery. Minimally invasive surgery brings little trauma to patients, and patients can recover in a short per...
