Fixable transparent neuroendoscopy sheath and fixing device

Abstract

The invention provides a fixable transparent neuroendoscopy sheath and a fixing device. The transparent neuroendoscopy sheath comprises a sheath tube and a sheath core, a sheath guiding head is arranged at one end of the sheath tube, and a stainless steel fixing sleeve head which matches with the fixing device is disposed at the other end of the sheath tube; and the sheath core is disposed in the transparent sheath tube, an end cap which is an arc structure is arranged at one end of the sheath core, a positioning sleeve head is disposed at the other end of the sheath core, and the end, with the end cap, of the sheath core is inserted in the transparent sheath tube and is in clearance fit with the transparent sheath tube. An arc-shaped clamp is disposed at one end of the fixing device and used for clamping the fixing sleeve head at the end of the transparent sheath tube, and the other end of the fixing device is connected with a serpentine retractor in a threaded manner and can lock the arc-shaped clamp. The fixable transparent neuroendoscopy sheath can be used for clearly judging the relation among normal brain tissues surrounding the working sheath and hematomas and conditions of cortex percutaneous nephrostomy channels, and greatly improves the surgery field and the visual field of a working channel. The fixing sleeve head of the transparent neuroendoscopy sheath is fixed with the serpentine retractor via the fixing device, so that the neuroendoscopy working sheath is effectively fixed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixable transparent neuroendoscopic sheath and a fixing device for minimally invasive treatment of hypertensive cerebral hemorrhage. Background technique [0002] Hypertensive intracerebral hemorrhage is the disease with the highest mortality rate among cerebrovascular diseases. The purpose of surgery is to remove the hematoma in time, reduce intracranial pressure, and reset the compressed and displaced brain tissue in time. Traditional craniotomy for hematoma evacuation involves large surgical trauma, difficulty in removing the hematoma at the dead corner, and many postoperative complications. Stereotactic hematoma puncture and drainage is less invasive, but has the disadvantages of low hematoma clearance rate and inability to stop bleeding. Neuroendoscopic surgery has developed from intraventricular lesions to intraparenchymal lesions, and expanded from cystic lesion...

AI Technical Summary

Problems solved by technology

Even small bleeding during the operation can easily contaminate the endoscopic mirror surface. Due to the residual hematoma in the operation, catheter drainage or urokinase injection is often required after the operation. If there is a large active bleeding, it is often forced to switch to craniotomy Hemostasis and hematoma removal, the advantages of neuroendoscopy are completely lost
