Problems solved by technology

In the past, percutaneous puncture was used to treat tumors in the body cavity or to take biopsies. The puncturer could only rely on CT scans to determine the depth and angle of the puncture point, and subjectively determine the depth and angle of the needle insertion. Due to the influence of body position changes during activities, puncture errors often occur, and repeated punctures are required, resulting in local tumor metastasis and serious complications such as pneumothorax, hemothorax, and organ bleeding.
[0003] The traditional CT-guided percutaneous puncture stereotaxic frame has the problems of inaccurate positioning during puncture, easy damage to normal tissues around the lesion, and poor puncture effect

Abstract

The invention relates to the technical field of percutaneous puncture, in particular to a percutaneous puncture stereotaxic frame based on CT guidance. The percutaneous puncture stereotaxic frame includes a frame body and a puncture mechanism, wherein the frame body is a reloading mechanism; an arc-shaped first chute is formed in the frame body; a first sliding block is slidably mounted in the first chute; the puncture mechanism is arranged below the frame body; the puncture mechanism is fixedly connected with the first sliding block through a connecting rod; the first sliding block drives thepuncture mechanism to adjust the position when sliding in the first chute, so that the puncture mechanism quickly reaches the position near a puncture position; and the puncture mechanism comprises afirst rack and a second rack which are perpendicular to each other. The puncture accuracy of a dangerous part is greatly improved, the work efficiency is improved, the holdup time of equipment such as CT is shortened, the CT utilization rate is increased, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of percutaneous puncture, in particular to a CT-guided stereotaxic frame for percutaneous puncture. Background technique [0002] With the continuous development of medical technology, many diseases can be diagnosed and treated through minimally invasive surgery through CT-guided percutaneous puncture without surgical incision. Especially for tumor diseases, pathological analysis is very important, and it is often necessary to obtain a clear pathological diagnosis before treatment to formulate a treatment plan. Therefore, for tumors in the body cavity, it is necessary to conduct percutaneous puncture biopsy under the guidance of CT positioning, or to place an argon-helium superconducting targeted surgical 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 biopsies. The puncturer could only rely on C...
