Abstract

A straight stitching and cutting device comprises a body, a cartridge (3) arranged on a cartridge frame (1), and a nail anvil (2) in pivoting connection with the cartridge frame (1). A push cutter rod (6) pushes a cutter (7) and a percussion block (5) to move. A boss (11) for insurance is arranged on the cartridge frame (1), an insurance block (8) is arranged on a pivot of the cutter (7), an elastic member (10) is arranged between the insurance block (8) and the cutter (7), and the elastic member (10) drives the insurance block (8) to be inclined when being free from an external force. The insurance block (8) is provided with at least one beading (81), the beading (81) is arranged on the end surface of the insurance block (8) in protruding mode, and when the push cutter rod (6) pushes the cutter (7) to move, the boss (11) is arranged in the moving direction of the beading (81) of the inclined insurance block (8) to enable the beading (81) to be blocked by the boss (11). The straight stitching and cutting device has the advantages of effectively preventing surgeons from performing the next surgery under the condition that the percussed cartridge is not changed, avoiding medical negligence and being simple in structure 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...
