Abstract

The invention discloses a CT puncture needle navigation device. According to the technical scheme, the device is characterized by comprising a guide hole, a rotating shaft is arranged on the inner wall of the guide hole, a guide rod is rotationally connected to the rotating shaft, the rear end of the guide rod extends out of the guide hole and is provided with a first electric telescopic rod, an auxiliary support is arranged at one end of the first electric telescopic rod, and a clamping hand used for clamping a puncture needle is arranged on the auxiliary support. The device has the followingbeneficial effects that during puncture, the auxiliary support is controlled to move through the first electric telescopic rod, the puncture needle clamped by the clamping hand is driven to conduct puncture, and therefore the puncture entering depth of the puncture needle is controlled so as to be aligned with the lesion position. Through mechanical automatic puncture, the puncture precision is improved, and the problem that a wound is enlarged due to the fact that manual puncture is prone to shaking is solved.

Description

technical field [0001] The invention relates to a medical instrument, more specifically, it relates to a CT puncture needle navigation device. 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 end of the main a...
