Noninvasive head stereotactic auxiliary device

Abstract

Provided is a noninvasive head stereotactic auxiliary device. The noninvasive head stereotactic auxiliary device includes a frame unit and a guide unit, wherein the frame unit includes a frame set including two mutually opposite and spaced connecting arms, a support set which is connected between the connecting arms and is close to the free end of the connecting arms, a first positioning piece which movably sleeves the support set, and two second positioning pieces which are respectively arranged on the connecting arms and are opposite to each other; the guide unit includes a carrier which iscoupled to the connecting arms and can rotate relative to the connecting arms, and a guide module which movably sleeves the carrier; the guide module is provided with a moving member which movably sleeves the carrier, and a guide member which is connected with the moving member and can rotate relative to the moving member; and the guide member is used for setting a medical device. The noninvasivehead stereotactic auxiliary device not only significantly reduces the pre-operative preparation time but also does not require intrusion into the head of a patient so as to avoid discomfort.

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...

AI Technical Summary

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
