Actuators, Instruments and Laparoscopic Surgical Systems

Abstract

The invention discloses an executive assembly, an instrument and a laparoscopic surgery system, and relates to the technical field of medical instruments. The executive assembly includes an executive head, a rotating shaft 1, a holding body and a pulling steel wire, wherein: the number of the executive head is two, and the two The two execution heads are arranged oppositely and are respectively rotatably connected with the holding body through the rotating shaft one. The holding body is provided with a through hole along its axial direction, and the pulling steel wire is passed through the through hole one and can move along the axial direction of the through hole one. The drawing steel wire is connected between the two execution heads in a transmission manner, and when the drawing steel wire moves along the axial direction of the through hole, the two execution heads are driven to clamp or open relative to each other. The executive component can realize the linear motion of the pulling steel wire, and drive the executive head to perform the steering movement, without the problem that the barbs or barbs cause incidental damage to human tissues.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an executive component, an instrument and a laparoscopic operation system. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, which is performed using laparoscope and related instruments. [0003] In laparoscopic surgery, both shearing instruments and forceps are commonly used instruments. Among them, the front end of the shearing instrument is a cutting head, which can realize the cutting of human tissue or medical materials; the front end of the forceps implements The head is a pliers head, which can realize the grasping, peeling, clamping, etc. of human tissue or medical materials. For example, forceps instruments include grasping forceps, needle forceps, stripping forceps, applying forceps and a series of instruments. [0004] The working principle of the existing shearing instruments and pliers instruments is to o...
