Description

A kind of intracranial hematoma suction punching positioning device

technical field

The invention belongs to the field of medical devices, and in particular relates to an intracranial hematoma suction and punching positioning device.

Background technique

Spontaneous cerebral hemorrhage is a relatively common type of stroke in clinical practice, with high mortality and disability rates, and there is currently no effective treatment method. Current studies have shown that craniotomy hematoma evacuation is more traumatic and cannot significantly improve the functional prognosis of patients compared with conservative treatment. Therefore, such an operation is not routinely recommended in current clinical work. Minimally invasive intracranial hematoma aspiration is less traumatic and simple to operate, and is currently routinely performed in many domestic hospitals. The key techniques for this type of surgery are hematoma localization, burr hole and drainage tube placement. Different hospitals or regions have different procedures and methods of operation. Some hospitals use a stereotaxic system for neurosurgery and cranial surgery, which is more accurate in positioning, but the operation is complicated and expensive, and it is not easy to be widely promoted; some hospitals use relatively simple positioning methods, such as CT plain film measurement positioning, bedside puncture , This method has higher requirements for the experience of the surgeon, and during the operation, due to the shallow depth of anesthesia for the patient, the fixing device is not firm, and the head often moves, resulting in inaccurate positioning. In addition, the use of the pistol drill has the following disadvantages: 1. The position of the scalp changes due to the separability of the scalp and the skull and the vibration of the pistol drill bit, and the preset skull drilling position cannot be judged according to the scalp; The change of the position makes it impossible to judge the position of the punched hole from the scalp, thus prolonging the operation time or requiring a second drilling, increasing the pain of the patient, and the corresponding risk of infection and bleeding. Aiming at the problems that the existing pistol drill cannot accurately drill the skull and the patient's head position is difficult to fix during the operation, the invention provides an intracranial hematoma suction and drilling positioning device.
