Abstract

The invention discloses an automatic guiding device for CT puncture needle. The technical solution of the device includes a first driving rod and a second driving rod. The first driving rod is connected with a first tooth plate meshed with a first gear. The second driving rod A second toothed plate meshing with the second gear is arranged on it, the first long sliding hole is slidably connected with a guide sleeve for the puncture needle to pass through to guide the puncture needle, and the lower end of the guide sleeve passes through the second long sliding hole and is connected with the puncture needle. The second long sliding hole is slidably connected. The invention has the following beneficial effects: the first driving rod and the second driving rod control the rotation of the first guide frame and the second guide frame respectively, and the guide sleeve moves in two directions along the first long sliding hole and the second long sliding hole respectively, so as to Stereoscopically change the angle of the guide sleeve to guide the puncture needle, so as to realize the automatic guidance of the puncture needle's piercing angle, so as to accurately locate the puncture angle.

Description

technical field [0001] The present invention relates to a kind of medical instrument, more specifically, it relates to a kind of automatic guiding device of CT puncture needle. Background technique [0002] Puncture is a diagnosis and treatment technique in which a puncture needle is inserted into the body to extract secretions for testing, inject gas or contrast agent into the body cavity for contrast examination, and inject drugs into the body cavity. The purpose of the puncture is to draw blood for testing, blood transfusion, infusion and catheter placement for angiography. In the puncture process, the puncture needle, a commonly used medical tool, is basically used, especially in some inspection items, which need to be checked by the puncture needle, such as the location of the tumor. [0003] According to the CT scan image, the medical personnel hold the puncture needle and puncture the human body. Before piercing, medical staff can only roughly judge the angle of pie...
