A cerebral hematoma removal system

Abstract

The invention discloses a cerebral hematoma removing system. The system mainly comprises a visual brain puncture needle and a brain tissue expander; the visual brain puncture needle comprises an outersleeve and an endoscope, the head of the outer sleeve is blocked, and the blocking part is made of a transparent material; the brain tissue expander comprises an outer tube and an inner tube; the inner tube is hollow to form a first through hole and a second through hole with different axes, the head of the inner tube is conical, and the tail of the inner tube is provided with a clamping groove;the outer tube is hollow and sleeves the inner tube, and a clamping part is arranged at the rear part of the outer tube; and when the inner tube reaches the set position of the outer tube, the clamping part of the outer tube can be clamped into the clamping groove of the inner tube by rotating the outer tube or the inner tube, and relative fixation of the positions of the outer tube and the innertube is achieved.

Description

technical field [0001] The invention discloses a brain hematoma removal system. Background technique [0002] Hypertensive intracerebral hemorrhage (HICH for short) has an acute onset and rapid progression, and is the most harmful single disease to humans. The root cause of the high fatality rate and high disability rate in patients with cerebral hemorrhage is caused by the intracerebral hematoma formed by cerebral hemorrhage. "Ultra-early, visualized, safe, minimally invasive, and one-time removal of intracerebral hematoma" is the dream of neurosurgeons today. [0003] Compared with the rapid development of cerebral ischemia surgery in recent decades, cerebral hemorrhage surgery has not made substantial progress due to the limitation of "taking egg paste from the deep part of the tofu brain without damaging the tofu brain". The core problem is that there are four technical problems in the evacuation of hematoma: [0004] 1. Visually and accurately search, locate, and con...

AI Technical Summary

Problems solved by technology

[0008] Existing surgeries (traditional craniotomy and hematoma evacuation, burr hole aspiration and drainage, neuroendoscopic hematoma evacuation) have made some progress in recent years, but each surgical method cannot "simultaneously" solve the above four technical problems. Can solve 1 or 2 of them at the same time

[0009] At present, blind detection of hematoma and confirmation of hematoma by blind sampling are common in all surgical methods; it is impossible to avoid new bleeding caused by "blind sampling of hematoma" from the principle level, leading to the risk of surgical failure; at the same time, some surgical methods also have intraoperative trauma The risk of brain tissue damage caused by large and unreasonable channels; and there are disadvantages such as cumbersome and cumbersome surgical operations, and high learning costs
