Endoscope and minimally invasive surgery robot

Abstract

The invention relates to the technical field of instruments for visually or photographically examining cavities or tubes of human bodies, and particularly relates to an endoscope and a minimally invasive surgery robot. The endoscope comprises a lens, a vertebra section assembly, an abdomen entering assembly and a control handle which are sequentially connected; the vertebra section assembly comprises a traction rope, a head end cone section bone, an elastic piece and a tail end cone section bone, wherein the head end cone section bone, the elastic piece and the tail end cone section bone are sequentially connected; the head end cone section bone is connected with the lens; the tail end cone section bone is connected with the abdomen entering assembly; one end of the traction rope is connected with the head end cone section bone, and the other end of the traction rope penetrates through the abdomen entering assembly and then is connected with the control handle; and after the traction rope is pre-tightened, the whole elastic piece is compressed, the head end cone section bone and the tail end cone section bone are parallel to each other, and the distance between the head end cone section bone and the tail end cone section bone is shortened. According to the endoscope, after the traction rope is installed, the vertebra section assembly is in a linear state, and good straightness is achieved. In addition, the endoscope has the advantages of being simple in structure, reducing cost and saving assembling time.

Description

technical field [0001] The invention relates to the technical field of instruments for visually or photographically inspecting cavities or tubes of a human body, in particular to an endoscope and a minimally invasive surgical robot. Background technique [0002] Endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. One has image sensors, optical lenses, light source lighting, mechanical devices, etc., and it can enter the stomach through the mouth or enter the body through other channels. The endoscope can be used to see the lesions that X-rays cannot show, which is beneficial to the doctor's diagnosis and treatment. Endoscopes generally include a vertebral segment assembly and a traction rope. The vertebral segment assembly can be bent by being pulled by the traction cord, so that the lens of the endoscope can reach the position that the doctor needs to reach and obtain a larger...
