Problems solved by technology

[0004] However, it is difficult to control the specific position during the inspection process. The movement process of the stent in the prior art is too rigid and will damage normal cells. In many cases, medical personnel still use manual control to control the position of the puncture needle. However, it is difficult to accurately determine the location of the lesion through manual control

Abstract

The invention discloses a full-automatic puncture needle positioner. The positioner comprises a puncture needle locating frame and a locating frame adjusting mechanism. The locating frame adjusting mechanism comprises, in a vertically successive manner, a feeding and discharge mechanism, an angle adjusting mechanism, a radian adjusting mechanism and a horizontal position adjusting mechanism, which are installed on an installation rack. When installation rack rises, the feeding and discharge mechanism, the angle adjusting mechanism, the radian adjusting mechanism and the horizontal position adjusting mechanism can orderly perform feeding, angle adjustment, radian adjustment and horizontal position adjustment of puncture needles on the puncture needle locating frame. Therefore, according to an image of CT scanning, the locating frame adjusting mechanism can accurately adjust the puncture needle locating frame and enable the puncture needles to arrive at accurate positions, thereby simplifying work of medical staff and achieving higher accuracy. Medical operators can directly perform puncturing according to the positions of the puncture needles.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a fully automatic puncture needle positioning device for a CT machine. Background technique [0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for laboratory tests, gas or contrast agent is injected into the body cavity for contrast examination, or drugs are injected into the body cavity. The purpose is to draw blood tests, blood transfusion, infusion and catheterization for angiography. [0003] The puncture needle is a common tool used in the puncture process, especially in some inspection items, which need to be checked by the puncture needle, such as the position of the tumor. In the prior art, the Chinese patent with the application number CN201420366671.5 discloses a puncture device based on CT machine images. The main arm of the main arm is also provided with a rotating stretching frame, one en...
