Embodiment Construction
[0023] Below in conjunction with accompanying drawing, the present invention will be further described:
[0024] The laser direction marking device used in conjunction with the laser projection positioning device includes a fixed plate 1, a lateral moving plate 2, a longitudinal moving plate 3, a longitudinal rotating slider 4, a transverse rotating ring 5, a slider gland 6, a guide tube 7 and a center Locator 8;
[0025] A square window 14 is set at the center of the fixed plate 1, and two first cylindrical pins 15 are arranged in the direction of the transverse axis of the fixed plate 1. The two first cylindrical pins 15 are symmetrically arranged on both sides of the square window 14, above the first cylindrical pin 15. Hingedly set the first pressing hand 9;
[0026] Lateral movement plate 2 is equal in size with fixed plate 1, and transverse movement plate 2 central positions are provided with longitudinal groove 16, and the central position of longitudinal groove 16 off...

The invention relates to a laser trapping device used in cooperation with a laser projection positioning device. The laser trapping device is characterized by comprising a fixed plate, a transverse moving plate, a longitudinal moving plate, a longitudinal rotating sliding block, a transverse rotating ring, a sliding gland, a guiding tube and a center positioning device. Accuracy of positioning can be improved substantially under guiding of the laser projection positioning device, it is avoided that in the operation process, errors of a physician cause reduction of accuracy, the direction of an operation tool is adjusted to coincide with the direction of laser positioning by adjusting the transverse moving plate, the longitudinal moving plate, the longitudinal rotating sliding block and the transverse rotating ring, after adjusting, pressing hands are used for compressing to fix the direction, and therefore a focus with a small operation diameter (such as the focus with the diameter of over 0.5 cm) can be successfully positioned. The laser trapping device reduces operation difficulty of the physician, improves operation accuracy, shortens operation time and reduces the amount of radiation received by a patient.
Description
technical field [0001] The invention relates to a laser direction marking device used in conjunction with a laser projection positioning device. Background technique [0002] In the minimally invasive surgery guided by the laser projection positioning device, the laser can accurately locate the foreign body or diseased tissue inside the human body. However, it is difficult for doctors to operate the surgical tools along the direction of the laser during the operation. When the direction of the surgical tools deviates from the laser positioning direction, it may lead to disastrous consequences. Therefore, it is important for minimally invasive surgery to avoid the doctor's operation error, treat the foreign body or diseased tissue in the human body according to the laser positioning direction, improve the safety of the operation, shorten the operation time, reduce the radiation exposure caused by repeated fluoroscopy, and reduce the tissue trauma and complications. significa...
