Embodiment 1

[0031] refer to figure 1 , 2 , a method for adjusting the launch position of a puncture locator to guide a pan-tilt, the improvement is that it includes the following steps:

[0032] S1, fixed puncture locator;

[0033] Fix the puncture locator on the side of the CT bed, and adjust the puncture locator so that the horizontal arm is horizontal and the guiding platform is vertical;

[0034] S2. Adjust the height of the cross arm;

[0035] Adjust the height H of the lowest end of the guide platform on the cross arm from the CT bed to 300mm or above;

[0036] S3. Adjust the guiding platform directly to the longitudinal centerline of the CT bed, that is, the projection of the guiding platform on the plane where the CT bed is located is located on the longitudinal centerline of the CT bed;

[0037] Control the horizontal arm to slide left and right on the vertical arm, so that the vertical projection of the guiding platform falls on the longitudinal centerline of the CT bed. At ...

Embodiment 2

[0053] On the basis of embodiment 1, in S2, the adjustment of the height above 300mm is to adjust the height of the cross arm according to the patient's fatness and thinness, so that the height H of the lowest end of the guiding platform from the patient's body surface is 300mm.

[0054] In this embodiment, the height of the cross arm can be adjusted according to the patient's fatness or thinness.

Embodiment 3

[0056] On the basis of Embodiment 1 or 2, in S3, the guiding platform will reset to the position of the moving origin MP after each puncturing work is completed.

Abstract

The invention relates to the field of auxiliary medical instruments, in particular to a method for adjusting a launching position of a guiding holder of a puncture position indicator. The method comprises the steps of fixing the puncture position indicator; adjusting the height of a cross arm; adjusting the guiding holder to directly face a longitudinal center line of a CT bed; and determining a needle entry point JP, a target point BP, a needle entry angle alpha and a tomography angle beta of puncture work, determining a movement distance of the guiding holder, and determining a movement distance of a CT bed board according to a computed tomography (CT) scanned image. Compared with the prior art, according to the method for adjusting the launching position of the guiding holder of the puncture position indicator provided by the invention, through determining the movement distances of the guiding holder and the CT bed board, the accuracy is greatly improved, the convenience in operation control during use is realized, and the accuracy of a positioning auxiliary light ray emitted by the guiding holder can be further improved.

Description

technical field [0001] The invention relates to the field of auxiliary medical instruments, in particular to a method for adjusting the launching position of a guiding platform of a puncture locator. Background technique [0002] Minimally invasive surgery is currently widely used in clinical fields such as needle biopsy and drug ion implantation. With the development and popularization of minimally invasive treatment and the maturation of technology, improving the accuracy of in vivo target positioning has become a difficult problem for doctors and the main reason for limiting the promotion of this treatment. The combination of puncture positioning system and high-grade spiral CT is an ideal guidance technology to improve puncture accuracy, safety and puncture efficiency. It is easy to operate, accurate in positioning, less traumatic, and has fewer complications, which has the significance of clinical application. [0003] In the prior art, Chinese patent CN100355398C disc...
