Abstract

The invention discloses a head solid locator, belonging to a technical field of medical machinery which includes a bracket, the upper surface of which is provided with a pair of lead rails arranged in parallel along the horizontal direction, a head fixing device which is used for confirming a head scanning datum layer surface and leading the scanning datum layer surface to be vertical to the horizontal upper lead rails, and is arranged on the front side between the two horizontal upper lead rails, one locating device which includes a door-shaped bracket and two lower ends of two upright posts of the door-shaped bracket are provided with an articulating device which can lead the door-shaped bracket to rotate along an X-shaft direction. The lower end of the articulating device is connected with a slide block arranged on the upper lead rails. A cross beam at the upper end of the door-shaped bracket is provided with a puncturing device which can slide along the cross beam. The invention solves the defect that the head locating device in the prior art can not realize 3D rotation and moving and has the advantages of simple structure and accurate location.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a head stereotaxic instrument used for puncturing and treating head lesion parts. Background technique [0002] Internal diseases of the brain, such as hematoma, abscess and cyst, usually require surgery to remove or cure these lesions. At present, ultrasound is used to treat thrombosis of cerebral thrombus. Whether it is puncture drainage or ultrasonic thrombolysis, the most important The problem is to determine the exact location of the lesion. The more advanced equipment used to determine the location of craniocerebral lesions is to use CT / MR machines to take pictures of the head, and determine the location of the lesions according to the patterns on the photos. However, since the photos are two-dimensional figures, it is still difficult to accurately reproduce the location of the lesion on the head during the operation, so experienced operators are required to perfor...
