Problems solved by technology

[0004] Although stereotaxic surgery is less invasive than craniotomy and does not require the use of general anesthesia, it takes a long time to prepare before surgery, and the formal surgery must be delayed for more than several hours
The reason is that stereotaxic surgery requires the head-mounted device to be locked on the patient's head through titanium nails. The process is very cumbersome and time-consuming, so it is not suitable for patients who are bleeding too much and are in immediate danger of life
In addition, locking the titanium nail into the patient's skull can cause a great deal of discomfort for the patient

Abstract

A noninvasive stereotactic assembly for guiding an instrument to a target within a patient's head includes a head frame subassembly and an instrument positioning subassembly. The head frame subassembly is secured to a skull in the patient's head to determine an X-axis and a Y-axis of a three-dimensional coordinate system. According to the coordinate of the target in the three-dimensional coordinate system, ring members, a movable bracket, a swivel member, and an instrument holder of the instrument positioning subassembly are displaced by predetermined angles to guide the instrument toward the target.

Description

technical field [0001] The invention relates to a head-mounted device, in particular to a non-invasive head-mounted stereotaxic auxiliary device. Background technique [0002] Craniotomy is one of the surgical procedures for the treatment of hemorrhagic stroke. It uses two-dimensional computed tomography (CT) scans to estimate the amount of cerebral hemorrhage, and after many years of clinical experience, the doctor evaluates the risk of surgery before deciding whether it can be done. conduct. The method is to first mark the projection mark of the center of the hematoma on the patient's skull, then make an incision, cut the dura mater, puncture and locate it, and finally insert surgical instruments to remove the hematoma. Craniotomy for the treatment of brain diseases is almost always accompanied by iatrogenic surgical trauma (Iatrogenic Surgical Trauma), that is, the injury caused by surgical instruments to patients. Iatrogenic surgical trauma may lead to functional defic...
