A minimally invasive stent channel gun

Abstract

The invention relates to a minimal-invasive bearer-channel gun. The minimal-invasive bearer-channel gun comprises a control wire, a double-membrane bearer, a conveying casing pipe and a control handle, wherein the double-membrane bearer comprises a wire mesh, an outer layer membrane and an inner layer membrane, and the wire mesh is arranged between the outer layer membrane and the inner layer membrane; the conveying casing pipe comprises a puncture head, a conveying rod and an outer casing pipe, the puncture head is arranged on the head part of the front end of the conveying rod, the double-membrane bearer sleeves the conveying rod, and the outer casing pipe detachably sleeves the exterior of the double-membrane support; the control handle comprises a casing pipe controller and a bearer top end controller, and the casing pipe controller and the bearer top end controller are rotatably installed on the control handle; the control wire comprises a bearer end wire, a casing pipe control wire and a bearer control wire. By adopting a minimal-invasive bearer-channel gun, a surgical cavity is provided for the endoscopic treatment, so that the surgical practical range of the endoscope can be greatly enlarged, and the tissue wound can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a minimally invasive stent channel gun for brain surgery. Background technique [0002] The development trend of modern neurosurgery is minimally invasive, precise and reliable, and effective control during the operation is convenient and easy to promote. Neurosurgeons from various countries have never stopped exploring. Neurosurgery technology, equipment and concepts have made great progress. At present, microscope technology and neuroendoscopy technology have been used as a major technology for small trauma, less bleeding, fast recovery, and minimally invasive operations; in recent years, with the continuous development of stereotactic technology, laser technology, ultrasound technology, and neuronavigation technology, There is a trend of fusion of various technologies. In the process of precise positioning and effective hemostasis, minimally invasive surgical ...
