Description

A laser point meter

Technical Field

The utility model relates to a laser position meter, in particular to a laser position meter used for positioning a CT device in a radiology department.

Background Art

CT-guided percutaneous soft tissue biopsy is one of the important diagnostic methods for diagnosing the nature of visceral soft tissue tumors, inflammatory lesions, and other superficial tumors. However, the ideal puncture needle positioned by CT is often at a certain angle to the vertical line. The operator must estimate the angle to accurately insert the needle and ensure successful puncture, especially when the tumor is small (such as <1cm). Accurate positioning is even more important. Most puncture doctors can only estimate the angle of the needle by eye, but there is usually a large deviation. The longer the needle stroke, the greater the error between the actual puncture site and the planned puncture site. Due to inaccurate needle insertion angle, the needle insertion angle must be repeatedly adjusted and then the needle must be reinserted, which not only reduces the success rate and work efficiency of the puncture, but also increases the patient's pain and increases the chance of complications.

After searching, the patent: A CT-guided percutaneous percutaneous stimulation laser positioning device (CN201910070068.X), including a locator, a horizontal rod and a bracket, one end of the horizontal rod is connected to the bracket, there are two horizontal rods, at least one of which can rotate around the bracket in the horizontal plane; a locator is provided on the horizontal rod, the locator can move horizontally along the horizontal rod and can rotate in the vertical plane relative to the horizontal rod; the locator includes a straight line laser, a tilt sensor and a display screen, and the plane where the locator laser light path is located is perpendicular to the vertical plane where the horizontal rod is located. Although the above structure can solve the positioning problem, it needs to be adjusted manually, which is inefficient and not very accurate.

In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a laser point meter with a new structure to make it more valuable for industrial use.
