Description

Technical Field

[0001] The utility model relates to a moving mechanism suitable for a laser point positioner. Background Art

[0002] 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 well in order to accurately insert the needle and ensure successful puncture, especially when the tumor is small (such as <1 cm). Accurate positioning is even more important. Most puncture doctors can only estimate the angle of the needle by the naked 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 angles, the needle insertion angle must be repeatedly adjusted and then the needle must be reinserted. This 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.

[0003] 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 in the horizontal plane around the bracket; a locator is provided on the horizontal rod, which can move horizontally along the horizontal rod and rotate in the vertical plane relative to the horizontal rod; the locator includes a linear laser, an inclination 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. The above movement is slow and the stability is insufficient.

The inner ends of the first secondary rotating shaft 42 and the second secondary rotating shaft 43 are connected to a moving roller 410.

[0026] The driving device 6 in the present invention is a servo motor.

[0027] In the present invention, the left movable side plate 2 and the right movable side plate 3 are both connected to auxiliary movable rollers 9 via a third secondary rotating shaft 8 .

[0028] In the present invention, adjustment holes 10 are provided on the left movable side plate 2 and the right movable side plate 3 located at the third secondary rotating shaft 8 , and the third secondary rotating shaft 8 is connected to the adjustment component 7 for assisting the adaptive adjustment of the position of the movable roller 9 .
