A detachable brain stereotaxic keyhole device

Abstract

The invention discloses a detachable brain stereotaxic keyhole device for inserting a drainage tube into a brain parenchymal lesion, which is characterized in that it has a bullet-shaped rotating body; wherein, the bullet-shaped rotating body includes: a first half The arc shell and the second semi-arc shell are interlocked to form a guide sleeve, and a mandrel passing through the guide sleeve; the diameter of the mandrel is larger than that of the drainage tube. The detachable brain stereotaxic keyhole device provided by the present invention adopts a bullet-shaped revolving body structure, which can not only play an orientation role, but also play a keyhole hemostasis effect, reduce the pain of the patient, and facilitate the rapid recovery of the patient. In addition, since the guide sleeve is formed by interlocking the first semi-circular shell and the second semi-circular shell, such a structure facilitates implantation of the catheter into the intracranial lesion, making it easy for the stereotaxic keyhole device to It is disassembled from the drainage tube, which is convenient for doctors to perform surgical treatment on intracranial lesions.

Description

technical field [0001] The invention relates to a medical device, in particular to a detachable brain stereotaxic keyhole device. Background technique [0002] Hypertensive intracerebral hemorrhage is a clinically common and frequently-occurring disease with three high characteristics of morbidity, disability and mortality. The current treatment methods for hypertensive cerebral hemorrhage include: large bone flap hematoma evacuation, small bone window hematoma evacuation, skull drilling catheterization hematoma aspiration and liquefaction drainage, stereotactic catheter hematoma aspiration and drainage, endoscopic hematoma evacuation surgery etc. Both at home and abroad are inclined to minimally invasive treatment. The reason is that minimally invasive treatment technology can not only save lives, but more importantly, can greatly reduce the disability rate and enable patients to recover as soon as possible. [0003] However, for intracranial hematoma, the process of tran...

Problems solved by technology

[0003] However, for intracranial hematoma, the process of puncturing the intracranial catheter through the cranial surface is actually a "black box" operation process. How to ensure that the drainage tube is accurately implanted into the hematoma cavity is a major technical problem.

At present, the intracranial drainage devices for minimally invasive treatment are not perfect. The performances are as follows: First, the lack of directional devices makes it difficult for doctors to ensure that the catheter can be accurately implanted into the hematoma in the process of inserting the catheter into the hematoma cavity based on their own operating experience. Center, easy to cause poor postoperative drainage; second, lack of keyhole hemostasis device, scalp bleeding during operation, affecting surgical operation; third, lack of detachable guiding keyhole device

Because in the existing intracranial drainage devices, the drainage tube is often integrated with the drainage bag, etc., once the drainage tube is placed in the hematoma cavity, the guide device of the intracranial drainage device is sleeved on the drainage tube and cannot be removed.
