Minimally invasive and expandable channel system for spine with new polymer material

Abstract

The invention discloses a novel high polymer material spine minimally-invasive expansible passage system. The novel high polymer material spine minimally-invasive expansible passage system is used for a spine minimally-invasive operation and comprises a strutting casing, a working casing and a fixed arm. The strutting casing, the working casing and the fixed arm are all made of medical high polymer materials. The working sleeve is formed by riveting the top portions of tube walls of two working sleeves. A connecting handle and a fixed clamping buckle are arranged on the top portion of the tube wall of each working sleeve. The connecting handle is connected with the fixed arm, and the fixed clamping buckle is used for fixing an outer light source. A color mark section is arranged on the strutting casing, the bottom of the strutting casing is in a cone shape and the top end of the strutting casing is provided with an anti-sliding section. Inserting depth of the strutting casing is easy to control, and the strutting casing is conveniently built in through manual operation. A cold light source is guided on the upper portion of the working casing to guarantee illumination of an operation area. Two handles of strutting pliers are respectively provided with an extending outer handle and an arc-shaped structure, and the strutting pliers are convenient to use. Main component materials are high-performance medical high polymer materials which are authenticated by Food and Drug Administration (FDA). Equipment manufacturing cost and equipment changing cost are low, equipment is disposal, and possibility of cross infection in operation is reduced.

Description

technical field [0001] The invention relates to a spinal minimally invasive operation system, in particular to a novel polymer material 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, and the working sleev...

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 on demand, the expansion forceps are convenient to use, and the manufacturing and replacement cost of the fixed arm is a new polymer material spinal minimally invasive expandable channel system
