Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of calibration platform suitable for laser positioner. BACKGROUND

[0002] CT-guided percutaneous soft tissue biopsy is one of the important diagnostic methods for diagnosing visceral soft tissue tumors, inflammatory lesions and other superficial tumor properties. However, the ideal puncture needle often forms a certain angle with the vertical line after CT positioning. The operator needs to estimate the angle to accurately insert the needle and successfully puncture, especially when the tumor is small (e.g., <1 cm). Precise positioning is more important. The angle of needle insertion can only be estimated by the naked eye for most puncture doctors, but there is usually a large deviation. The longer the needle insertion distance, the greater the error between the actual puncture site and the planned puncture site. Due to inaccurate needle insertion angle, the needle insertion angle often needs to be adjusted repeatedly before reinsertion. This not only reduces the success rate of puncture and work efficiency, but also increases the pain of patients, making the risk of complications greater.

[0003] After searching, the patent: a CT-guided percutaneous puncture laser positioning device (CN201910070068.X) includes a positioner, a horizontal rod, and a bracket. One end of the horizontal rod is connected to the bracket. There are two horizontal rods, and at least one horizontal rod can rotate in the horizontal plane around the bracket. The positioner is provided on the horizontal rod and can move horizontally along the horizontal rod and rotate in the vertical plane relative to the horizontal rod. The positioner includes a linear laser, an inclination sensor, and a display screen. The plane of the positioner laser light path is perpendicular to the vertical plane of the horizontal rod. Although the above structure can solve the positioning problem, it needs to be adjusted manually, which is slow and has low accuracy. The laser positioner needs to be calibrated before work, otherwise it will affect the subsequent accuracy. Calibration is usually complete in the above structure, and is implemented by software and corresponding calibration chart. However, such operation is prone to low accuracy.

[0004] In view of the above-mentioned defects, the present design person actively researches and innovates to create a new structure of calibration platform suitable for laser positioner, so as to have more industrial utilization value. INVENTION CONTENTS
