Deep brain adjustable endoscope channel system

Abstract

The invention discloses a deep brain adjustable endoscope channel system and belongs to the technical field of medical auxiliary instruments, the deep brain adjustable endoscope channel system comprises a base cylinder and a tissue expansion winding drum, the tissue expansion winding drum is curled into a cylinder shape and then penetrates through an inner cavity of the base cylinder, and an inner diameter adjusting mechanism is arranged in the middle of the base cylinder; and the tissue expansion winding drum is arranged on the base cylinder and matched with the inner diameter adjusting mechanism, two fixing clamping strips are symmetrically arranged on the two sides of the base cylinder, the base cylinder, the tissue expansion winding drum and the inner diameter adjusting mechanism are arranged, the inner diameter adjusting mechanism can be expanded and contracted, and therefore the tissue expansion winding drum which is curled into a cylinder shape is driven to be expanded and contracted. By means of the structure, the pipe diameter of the tissue expansion winding drum can be adjusted according to operation requirements, a deep brain prying space can be opened for an operator, the exposure area can be directly increased, a good view and a wider operation space are provided for a doctor in an operation under the more stable and safer condition, and the operation becomes safer and more convenient.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a deep brain adjustable speculum channel system. Background technique [0002] During neuroendoscopic deep brain surgery, the endoscope needs to be introduced into the deep brain of the patient through a channel system. There are also some channel systems on the market, mainly a syringe-like structure made of transparent materials. The structure is passed through a pneumatic arm or The automatic retraction system is used in conjunction with several problems. First, it cannot cooperate with our pneumatic arm or automatic retraction system. It needs the support of the doctor's assistant and increases the fatigue of the doctor. Second, its size is Fixed, in some cases, when it is necessary to increase the diameter of the channel to obtain better exposure, it often cannot meet the requirements, so we propose a deep brain adjustable speculum channel system.
