Abstract

The invention discloses a linear suturing / cutting device, comprising a body, a nail cartridge frame and a nail anvil, wherein a nail cartridge is arranged on the nail cartridge frame; the nail anvil is connected with the nail cartridge frame in a pivot way; a cutter pushing rod pushes a cutter and a trigger block to move; a boss playing a role in insuring is arranged on the nail cartridge frame; an insuring block is arranged on the cutter in the pivot way; an elastic piece is arranged between the insuring block and the cutter; in a state of no external force, the elastic piece drives the insuring block to incline; at least one shoulder is arranged on the insuring block; the shoulders are arranged on the end face of the insuring block in a protruding way; when the cutter pushing rod pushes the cutter to move, the boss is located in the moving direction of the shoulders of the inclined insuring block; therefore the shoulders are withstood by the boss. The linear suturing / cutting device has the main beneficial effects of effectively preventing a doctor from implementing next operation under the circumstance of not replacing the triggered nail cartridge, preventing medical incidents from occurring and being simple and effective in structure.

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...
