Abstract

The invention discloses a rope fixing structure, a surgical instrument, a split surgical device and a robot. The rope fixing structure comprises a first traction rope, a second traction rope, a rigid connecting piece and a locking sleeve. The rigid connecting piece is provided with a first rope groove and a second rope groove, and the first rope groove and the second rope groove intersect to form at least one intersection point. The first pulling rope is embedded in the first rope groove and extends out of the first end of the rigid connecting piece, and the second pulling rope is embedded in the second rope groove and extends out of the first end of the rigid connecting piece. At the intersection point, the first pulling rope or the second pulling rope protrudes out of the surface of the rigid connecting piece, the locking sleeve is arranged on the surface of the rigid connecting piece in a sleeving mode, and at the intersection point, the locking sleeve is in interference fit with the first pulling rope or the second pulling rope. The two traction ropes are crossed and overlapped to form the convex block so as to form a fixing mode of an interference fit connection relation, more other accessories do not need to be additionally used, the fixing structure is simple, the size is small, and the operation visual field of surgical instruments can be expanded.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a rope fixing structure, a surgical device, a split surgical device and a robot. Background technique [0002] In the medical device industry, in order to realize the multi-degree-of-freedom movement of the device, the use of ropes for connection and drive has gradually become more common. [0003] In the existing surgical instruments, when the rope is fixed, in order to facilitate disassembly and maintenance, a special special-purpose crimping rope buckle is usually used or a bolt is used to clamp the rope for fixed connection. [0004] However, this fixing method of the rope makes the volume of the connection structure larger in practical applications. When operating in the limited space in the abdominal cavity, the larger structure volume affects the surgical field of view due to the closer distance from the endoscope lens. Operation is restricted. Conte...
