Problems solved by technology

However, doctors need to hold surgical instruments in clinical operations and adjust the direction according to the images on the display of the neuronavigation system. It is more difficult for doctors to operate multiple surgical instruments at the same time, such as holding an endoscope in their hands, and then placing other surgical instruments. It is very difficult to introduce surgical instruments into the body through the endoscope and perform surgery

Embodiment Construction

[0023] Below in conjunction with the process of accompanying drawing and operation the inventive method is described in further detail:

[0024] 1) CT scan imaging

[0025] The patient's hair is first shaved. Then glue the scalp reference frame, such as figure 1 shown. The upper ball of the scalp reference frame is used to reflect infrared rays, and the lower ball is used for visualization in CT scans. The relative position between the infrared reflective ball and the CT scanning developing ball is fixed. The patient undergoes a CT scan with an extremely light scalp fiducial frame. When the skin is cut, the scalp shifts due to tension. For this reason, two scalp reference frames are generally used before CT scanning, one on the left and one on the left. If the doctor decides to operate on the left side of the brain, then the left scalp reference frame will not be used. vice versa.

[0026] 2) Computerized 3D reconstruction of CT image data

[0027] In addition to cran...

Abstract

The invention relates to a two-point navigation stereotactic method and equipment. According to the principle that two points determine a straight line, namely, two points determine a direction, two control points on a positioning rod are moved to adjust the direction of the positioning rod so that a surgical instrument reaches to a designated position and points to the focus. In the whole operation process, the doctor only needs to remotely control the surgical instrument so that the surgical instrument is positioned accurately in the designated position and clamped stably. The two-point navigation stereotactic method ensures high positioning accuracy and solves the problem of complex operation of the traditional positioning method.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a two-point navigation stereotaxic method and equipment thereof. Background technique [0002] The success or failure of neurosurgery, especially craniotomy, depends largely on the accuracy of positioning. In order to accurately locate the lesion, various methods have been studied. With the development of technology and computer software writing, non-contact (or frameless) accurate positioning of lesions has been realized. However, doctors need to hold surgical instruments in clinical operations and adjust the direction according to the images on the display of the neuronavigation system. It is more difficult for doctors to operate multiple surgical instruments at the same time, such as holding an endoscope in their hands, and then placing other surgical instruments. It is very difficult to introduce surgical instruments into the body through the endoscope and perform surgery. ...
