Embodiment Construction

[0021] as attached figure 1 to attach Figure 5 As shown, the present invention provides a novel CT-guided puncture auxiliary positioning device, which is used to assist in locating the insertion point of the puncture needle and indicating the needle insertion path, and can be applied to puncture biopsy operations of lungs, kidneys, livers and other organs. The puncture auxiliary positioning device 3 includes components such as a scaled base 5, a scaled vertical rail 10, a scaled horizontal rail 14, an angle plate 16, and a needle cover 19. The scaled base 5 is provided with a linear track A 6, a linear track A 6 The slide block A 8 is slidably connected inside, and the slide block A 8 moves linearly in the Z direction along the linear track A 6; the vertical rail 10 with scale is installed on the slide block A 8, and the vertical rail 10 with scale is provided with a linear track B12 , the linear track B12 is slidably connected with a slider B 21, and the slider B 21 moves l...

Abstract

The invention relates to a novel CT-guided puncture auxiliary positioning device which comprises a base with scales, a vertical rail with scales, a transverse rail with scales, an angle scale and a needle sleeve, a linear rail A is arranged on the base with the scales, a sliding block A is slidably connected into the linear rail A, and the sliding block A does Z-direction linear motion along the linear rail A; the vertical rail with the scales is installed on the sliding block A, a linear rail B is arranged on the vertical rail with the scales, a sliding block B is connected into the linear rail B in a sliding mode, and the sliding block B conducts Y-direction linear motion along the linear rail B; a transverse rail with scales is mounted on the sliding block B and does X-direction linear motion along the sliding block B; the angle scale is installed on the transverse rail with the scales, an arc-shaped rail is arranged on the angle scale, a needle sleeve is connected to the arc-shaped rail in a sliding mode, and the needle sleeve rotates along the arc-shaped rail; compared with the prior art, dependence of puncture on experience of an operator can be greatly reduced, puncture adjustment is reduced, puncture time is shortened, and complications caused by multiple times of needle insertion adjustment are avoided.

Description

[technical field] [0001] The invention relates to the field of medical instruments, in particular to a novel CT-guided puncture auxiliary positioning device. [Background technique] [0002] CT-guided needle biopsy is widely used in biopsy sampling of lung, liver, kidney and other organs with suspicious lesions, and is an important diagnostic method. Although doctors can view lesions in the human body through medical images, the actual location of lesions still needs to be judged subjectively by doctors. At present, needle biopsy mainly relies on the experience of doctors to perform "blind puncture", and there is a phenomenon that the puncture needle has to be adjusted many times to reach the lesion. Taking percutaneous lung biopsy as an example, blind puncture is likely to cause complications such as pneumothorax, pulmonary hemorrhage, and hemoptysis. The workload of doctors is heavy, the patients are relatively painful, and it takes a long time for medical resources. [Co...
