Body surface positioning device for CT diagnosis and operation method of body surface positioning device

Abstract

The invention relates to the technical field of CT diagnosis, in particular to a body surface positioning device for CT diagnosis. The body surface positioning device comprises a first positioning piece, a second positioning piece and a clamping block, wherein the first positioning piece and the second positioning piece are the same in structure, evenly-distributed connecting ropes are arranged between and connected with the lower end of the first positioning piece and the upper end of the second positioning piece, a gluing layer is arranged at the lower end of the second positioning piece, fixing strips are fixedly arranged on the two sides of the first positioning piece, and the ends, away from the first positioning piece, of the fixing strips are fixedly connected with one end of a gooseneck pipe. When the body surface positioning device is used, the second positioning piece is fixed on the body of a patient through the gluing layer, and then the first positioning piece is fixed to a bed board through the clamping block; and in an axial CT scanning process, the second positioning piece fluctuates up and down along with the body of the patient, the position of the first positioning piece is kept unchanged, the second positioning piece and the first positioning piece are combined, so positioning precision can be effectively improved, and follow-up operation can be smoothly carried out conveniently.

Description

technical field [0001] The invention relates to the technical field of CT diagnosis, in particular to a body surface positioning device for CT diagnosis and an operating method thereof. Background technique [0002] With the development of imaging and computer software technology, more and more clinical applications of precision medicine are being applied, and the core is the "precision guidance technology" guided by images. "Guidance" needs to make some image marks on the body surface of the human body. The marks have dual visibility of images and objects, and are important reference marks for measuring the spatial position of the lesion and a certain point on the body surface, so as to accurately see the deep part of the body through percutaneous fixed-point puncture. Less than disease. At present, although some people use high-density metal wires arranged in parallel to fix together as CT positioning puncture marks, which brings a certain degree of convenience and accura...

Problems solved by technology

At present, although some people use high-density metal wires arranged in parallel to fix together as CT positioning puncture marks, which brings a certain degree of convenience and accuracy, but in actual use, due to the process of human breathing, the body will continue to move up and down. Therefore, we propose a CT diagnosis body surface positioning device and its operation method
