Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0025] This embodiment provides a working channel for endoscopic neurosurgery, which is made of a rectangular material curled into a roll structure, and the diameter of the roll can be reduced under the action of an external force, and the diameter can be increased under the action of its own tension. The rectangular material is transparent PVC (polyvinyl chloride resin) or TPE (thermoplastic elastomer) material. The length of the rectangular material is 50-70mm, the width is 40-60mm, and the thickness is 0.5-0.8mm, and the specific size can be adjusted according to the needs of the operation.

[0026] The above-mentioned neuroendoscopic surgery working channel can be self-made through the following simple steps, including:

[0027] (1) Take an ordinary medical intravenous infusion set, and cut out the Murphy's tube with sterile...

Abstract

The invention belongs to the field of medical devices and provides a neuroendoscopic operation working channel and a method for manufacturing the same. The working channel is of a winding drum structure through the curling of a rectangular material, the winding drum can reduce its diameter under the effect of external force and can increase its diameter under the effect of its tension. The neuroendoscopic operation working channel is simple to manufacture and low in cost, can effectively replace an expensive retractor, is better in effect and reduces the damage to organs.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a neuroendoscopic operation working channel and a self-made method thereof. Background technique [0002] Neuroendoscopic evacuation of intracranial hematoma is a new surgical method that has been gradually carried out at home and abroad in recent years. This operation requires an endoscopic working channel to open the brain tissue and provide space for endoscopic observation and instrument operation. . Vycor Corporation of the United States produces a viewsite tubular brain retractor. However, this kind of retractor and the neuronavigation puncture needle that needs to be positioned during the operation cannot be properly fixed, and the puncture may cause deviation under the guidance of the navigation, and the accuracy is not enough; Can cause major damage to brain tissue. Contents of the invention [0003] The purpose of the present invention is to overcome the...
