CT-guided puncture positioning fixator

Abstract

The invention discloses a CT-guided puncture positioning device, and relates to the technical field of medical positioning puncture. The positioning device comprises a circular four-leg support structure, a puncture needle guide groove, a vertical dovetail groove, an arc-shaped sliding groove and a transparent circular sliding groove, wherein the circular four-leg support structure is attached tothe skin of a patient to play a fixing role; the circular sliding groove can rotate by 360 degrees on a circular base; the arc-shaped sliding groove linearly moves along the transparent circular sliding groove; the vertical dovetail groove can do rotary arc-shaped movement along the arc-shaped sliding groove; and the puncture needle guide groove can move in the vertical direction of the vertical dovetail groove. According to the positioning device, precise positioning of an affected part of the patient is completed by means of movement of the components. By means of the design, the CT-guided puncture precise positioning and body surface fixing assistance functions are achieved, so that the CT-guided puncture technology can be used for pathological diagnosis of lesions of all parts of the whole body, and the convenience is provided for CT-guided lesion minimally invasive treatment; and the CT-guided puncture positioning device has the characteristics of being reasonable and reliable instructure, accurate in positioning, easy to operate, good in assisting effect and wide in application range.

Description

technical field [0001] The invention relates to the field of medical puncture technology and the field of part manufacturing technology, in particular to the field of high-efficiency puncture assistance technology. Background technique [0002] The existing medical CT positioning and puncture devices consist of a puncture needle guiding device, a fixing device, and a positioning device. Most of the current CT puncture positioning technologies on the market have problems such as long positioning time, low positioning accuracy, and poor reliability. It must be painful, and it also increases the time for doctors to diagnose. Moreover, the design of the guide rail in the CT puncture positioning device is crucial to the efficiency of puncture and the determination of the best path. [0003] Through the movement of each component, the positioning of the complex three-dimensional position is realized. The whole device is composed of a circular four-legged support structure, a tra...
