Abstract

The invention relates to a suturing and cutting device for an endoscopic surgery. The suturing and cutting device comprises a main body, a nail head portion and a link mechanism, wherein the nail head portion is connected to the far end of the main body by virtue of the link mechanism in a mode of being capable of swinging relative to the axial direction of the main body; and the link mechanism comprises an operating rod, a link component and a connecting component. According to the suturing and cutting device, an adaptor is added between the main body and the nail head portion; and one end of the adaptor is hinged with the main body and the other end is hinged with the nail head portion. Through transmission of the link component and the connecting component when action force is applied to the operating rod, the nail head portion swings for the first time relative to the axial direction of the main body, and as the adapter swings in a same direction relative to the axial direction of the main body, the nail head portion swings for the second time relative to the main body, and a swinging angle can be larger, so as to better satisfy the demand of the endoscopic surgery.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to an instrument for surgery, in particular to a slit-cutting device for endoscopic surgery with a rotatable head. Background technique [0002] Surgical suturing devices have been widely used for suturing wounds, suturing and cutting internal tissues, and a suturing device suitable for endoscopic surgery has also been developed. Laparoscopic surgery, also known as laparoscopic surgery, replaces direct vision with the naked eye with electronic mirrors, and replaces fingers with slender instruments. Observation, diagnosis, cutting, suturing and other treatments of lesions. [0003] A stapling device for laparoscopic surgery generally includes an instrument platform and a head detachably mounted on the platform. The instrument platform includes a firing handle, and the detachable head includes a body and nails mounted on the distal end of the body. The head, the body includes a casi...
