Abstract

A flexible surgical instrument, the flexible surgical instrument comprising a flexible end part (01) and a control box part (02), mechanically connected between the flexible end part (01) and the control box part (02); the flexible end The part (01) includes the unfolded part (011), the joint part (012) and the end part (013) which are connected in sequence; (3), a pair of bolts (4) and long joints (5); the deployment part (011) also includes two ropes (1111); preferably, the two ropes pass through the above parts and control the deployment action , the rope on one side is shortened, and the rope on the other side is lengthened, so as to achieve the action of bending and unfolding.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a flexible surgical instrument that can be used at the end of a mechanical arm, or a flexible instrument for minimally invasive anus-preserving surgery for transanal tumor resection. Background technique [0002] TEM (Transanal Endoscopic Microsurgery) is a minimally invasive sphincter-preserving surgical method for transanal tumor resection. Through a specially designed proctoscope (Richard Wolf Medical Instruments Corporation, Knittling, Germany), the high-quality visual system and pressure regulation are charged. Aspirator is combined. The diameter of the rectoscope is 4cm, and the shaft length is divided into two types: 12cm and 20cm, to adapt to the lesions in different parts. It is fixed on the operating table through a fixing device. There are four operation holes sealed with special rubber sleeves on the panel of the rectoscope. The endoscopic equipment includes tissue grasping f...
