Problems solved by technology

[0003] At present, neuroendoscopic technology has been widely developed in developed countries and gradually popularized in China. However, the existing endoscopic sheaths on the market have many shortcomings, such as blindness in the hematoma puncture process. Although there are navigation and other positioning software to assist puncture, they cannot Observing the surrounding tissue structure during the puncture may still easily cause iatrogenic injury and puncture failure; the inner diameter of the puncture sheath is too large (all above 2cm), resulting in greater damage to the brain tissue during the operation; adjust the direction of the sheath during the operation Difficult, the operation is relatively complicated; it is difficult to flush the operation area during the operation, and it is easy to affect the operating field of vision; and the whole set of devices is expensive, and it has not been widely used and popularized clinically

Abstract

The invention discloses a disposable visualized brain puncture guidance device applied in an intracerebral hematoma evacuation operation during treatment of hypertensive cerebral hemorrhage. The device includes a puncture inner core assembly, a limiting sleeve pipe assembly and a handheld flushing cup joint assembly. The puncture inner core assembly is sleeved with the limiting sleeve pipe assembly, the limiting sleeve pipe assembly is in cup joint with the handheld flushing cup joint assembly through an oblique opening in the outer end of the handheld flushing cup joint assembly, and the puncture inner core assembly, the limiting sleeve pipe assembly and the handheld flushing cup joint assembly are all made of transparent materials; during puncture and the operation, the surrounding tissue can be observed clearly, the puncture success rate is increased, and iatrogenic injuries are reduced. By supporting a second adjusting arm, the direction and depth of a sheath tube in the skull canbe adjusted; the second adjusting arm can be externally connected to a medical S-shaped retractor for fixation. Secondary expansion can be achieved, and damage caused by excessive primary expansion isavoided. The device has the advantages of being visualized, high in flexibility and stability, capable of reducing damage of brain tissue, high in practicability, easy to operate, low in cost and thelike.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable visualized brain puncture guide device used in intracerebral hematoma evacuation in the treatment of hypertensive cerebral hemorrhage. Background technique [0002] Hypertensive intracerebral hemorrhage is a common emergency and critical illness in neurosurgery, with the characteristics of high mortality and disability. Craniotomy and evacuation of hematoma is one of the important methods for the treatment of cerebral hemorrhage. However, traditional craniotomy involves large surgical trauma, difficulty in evacuating marginal hematoma, and many postoperative complications. With the advancement of endoscopic equipment and the gradual maturity of endoscopic treatment of cerebral hemorrhage, more and more attention has been paid to endoscopic minimally invasive treatment of cerebral hemorrhage, which has the advantages of short operation time, small trauma, and ...
