A minimally invasive expandable channel system with a new polymer material built-in fiber optic spine

Abstract

The invention discloses a novel high polymer material spine minimal invasion expandable channel system with internally arranged optical fibers for minimally invasive spine surgery systems. The novel high polymer material spine minimal invasion expandable channel system comprises an opening cannula, a working sleeve and a fixing arm which are made of medical high polymer materials. The working sleeve is formed by movably riveting tops of walls of two working sleeve tubes, and connection handles are further arranged at the tops of the walls of the working sleeve tubes and connected with the fixing arm. Optical fiber modules are arranged in the working sleeve, color identification sections are arranged on the opening sleeve, the bottom of the opening sleeve is tapered, and anti-skidding sections are arranged at the top of the opening sleeve. According to the novel high polymer material spine minimal invasion expandable channel system, the opening cannula implanting depth is easy to control, and the opening cannula is convenient to implant manually; the opening sleeve can be opened from the upper portion to expand the bottom area, and the internally arranged optical fiber modules facilitate lightening in the working sleeve; and stretching outer handles and arc structures are arranged on two handles of opening pliers respectively, so that the utilization is facilitated; and equipment is low in manufacturing and exchanging cost and disposable, so that the possibility of cross infection in surgery is reduced.

Description

technical field [0001] The invention relates to a spinal minimally invasive operation system, in particular to a novel polymer material built-in optical fiber spinal minimally invasive expandable channel system. Background technique [0002] Commonly used surgical instruments in existing spinal minimally invasive surgery systems include distraction sleeves, working sleeves, fixed arms, and spreader forceps. Generally, the function of distraction sleeves is limited to step-by-step insertion along the incision to expand the surgical work. However, it is difficult to judge whether the cannula has reached the surgical area after it is inserted into the body, and the outer end of the first placed distraction cannula has no suitable parts for grasping, which makes it inconvenient to insert the cannula; the working sleeve is fixed The columnar structure has a single structure, and in minimally invasive surgery, it is often necessary to expand the bottom of the target operation area...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems in the general spinal minimally invasive surgery system that the insertion depth cannot be grasped by the expansion sleeve, the single bottom of the working sleeve structure cannot be expanded on demand, the force is inconvenient to use the expansion forceps, and the fixed arm is damaged and the replacement cost is high. The present invention provides a The insertion depth of the expansion sleeve is easy to control, the bottom of the working sleeve can be expanded and fixed as needed, and the built-in optical fiber is easy to use, and the manufacturing and replacement costs of the fixed arm are new polymer materials.
