Problems solved by technology

First of all, a positioning scan must be performed before the head frame is installed, which is not conducive to the rescue treatment of critically ill patients, will increase the risk of accidents, and reduce the success rate of rescue
Secondly, it will increase the workload of medical staff and increase medical costs
In addition, positioning scanning after installing the head frame may lead to contamination of the surgical area, which needs to be re-sterilized before surgery, increasing the risk of infection

Embodiment Construction

[0020] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0021] Please refer to Figure 1-3 , the stereotaxic auxiliary positioning device based on body surface landmarks includes a connector 1 , a measuring ruler 2 , a bow frame 3 and a probe 4 . The connector 1 securely fixes the auxiliary positioning device on the stereotaxic instrument 5 through mechanical fixing methods such as bolts, pins or buckles. The bow frame 3 spans between the connector 1 and the probe 4 , and the connector 1 and the probe 4 are respectively mounted on two ends of the bow frame 3 . There is a scale on the measuring ruler 2, which is slidably connected with one end of the bow frame 3. The probe 4 is located on the same straight line as the measuring ruler 2 and the connector 1 . When performing auxiliary positioning, adjust the deflection of the stereotaxic instrument 5 and slide the bow frame 3,...

Abstract

The invention discloses an auxiliary positioning device for a stereotaxic instrument based on landmark points on the body surface. Its structure includes a connector, a measuring ruler, a bow-shaped frame and a probe. Between the probe and the probe, the probe is located at one end of the bow frame, on the same line as the measuring ruler and the connector. When in use, the connector is fixed on the stereotaxic instrument, and the head ends of the probe are adjusted one by one by adjusting the body orientation instrument. Touch the body surface marker points and read the two azimuth and distance data of each body surface marker point relative to the center point of the stereotaxic instrument, and input them into the electronic computer imaging workstation for auxiliary positioning. The auxiliary positioning device for stereotaxic apparatus based on body surface marker points of the present invention can make the use of stereotaxic apparatus more convenient, fast, safe and effective, reduce the risk of accidents and the workload of medical personnel, improve the success rate of rescue, and reduce medical costs and risk of infection.

Description

technical field [0001] The invention relates to an auxiliary positioning device for a stereotaxic instrument, in particular to an auxiliary positioning device for a stereotaxic instrument based on body surface marker points. Background technique [0002] Stereotaxic instrument is a surgical instrument that uses imaging scanning technology (CT, MRI, etc.) to guide microelectrodes, puncture needles and other surgical instruments into specific target points in the body, to take tissue samples, destroy tissue at target points, or remove lesions. Stereotaxic instruments are usually equipped with a calibration frame with positioning marks on it. After positioning and scanning, the imaging workstation converts the virtual coordinates of the imaging system into the physical coordinates of the surgical area through coordinate mapping transformation, so as to accurately locate the target point and guide the surgical instruments to perform the operation. operate. [0003] There are ma...
