CT (computed tomography) guidance percutaneous puncture three-dimensional positioning frame

Abstract

The invention discloses a CT (computed tomography) guidance percutaneous puncture three-dimensional positioning frame. The CT guidance percutaneous puncture three-dimensional positioning frame is provided with a left camera and a right camera, a picture is converted by a sensor to a digital signal recognized by a controller so as to accurately locate a locator; moreover, the entire puncture process of a puncture needle is monitored, so that a purpose of precise puncturing can be realized; and the CT guidance percutaneous puncture three-dimensional positioning frame is provided with four contactors which are accurately located by the locator, so that the fixture in contact can be improved, the pain of a patient in the puncturing process can be alleviated, more precision in location during the percutaneous puncture process can be realized, the focal cells can be accurately destroyed, the normal tissue on the periphery of a focus is not damaged, and a good puncture effect can be realized. By adopting the CT guidance percutaneous puncture three-dimensional positioning frame, a focal target point can be accurately punctured, the focal tissues can be more effectively killed, and the unnecessary injury and complication can be reduced. The CT guidance percutaneous puncture three-dimensional positioning frame has the advantages of more accuracy in target point location, more convenience and rapidness in operation, capability of reducing the repeated puncturing and complication and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a CT-guided percutaneous puncture stereotaxic frame. Background technique [0002] At present, many diseases can be diagnosed and treated by CT positioning guided percutaneous puncture without surgical incision, and minimally invasive surgery. Especially for tumor diseases, pathological classification is very important, and it is often necessary to obtain a clear pathological diagnosis before treatment. treatment solutions. Therefore, for tumors in the body cavity, it is necessary to conduct percutaneous biopsy under the guidance of CT positioning, or to place an argon-helium superconducting targeted surgery system, that is, an argon-helium knife, to treat the tumor thoroughly. In the past, percutaneous puncture was used to treat tumors in the body cavity or to take biopsy. The puncturer could only rely on CT scans to determine the depth and angle of the puncture point, ...
