Digital information CT positioning puncture angle guider for metal capillary tube identification

Abstract

The invention relates to a digital information CT positioning puncture angle guider for metal capillary tube identification, which comprises a guider body, one side of the guider body is fixedly connected with a guider clamping handle, and the guider body comprises at least two layers of upper plate bodies and lower plate bodies which are correspondingly arranged up and down; puncture needle through holes which are distributed in rows and columns in a matrix mode are evenly formed in the upper plate body and the lower plate body respectively, a central metal hollow capillary tube is embedded in the puncture needle through hole located in the geometric distribution center, and a first identification group, a second identification group and a third identification group which are used as rowidentifications are further embedded in the guider body. The central intersection point of the first identification group, the second identification group and the third identification group is locatedat the central metal hollow capillary tube. According to the invention, the first identification group, the second identification group and the third identification group are used as row identifications, and are matched with a guide template of digital row information, so that accurate execution of a radioactive particle implantation plan and various minimally invasive puncture diagnosis and treatment technologies is ensured, the manufacturing is simple and convenient, and the product is suitable for large-scale market popularization.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a digital information CT positioning puncture angle guide for metal capillary marking. Background technique [0002] The puncture angle guidance can be used in various non-vascular intervention minimally invasive diagnosis and treatment operations. Including: radioactive seed implantation, argon-helium freezing, radiofrequency, microwave, ultrasound, nanoknife ablation, etc. Other minimally invasive treatment methods include: puncture biopsy of tiny nodules in the liver and lungs, cyberknife gold standard implantation, puncture and drainage of small abscesses in the chest cavity and abdominal cavity, gastrostomy, metastatic tumors in the liver and lungs, liver, kidney, pancreas, and prostate Minimal invasive diagnostic procedures such as needle biopsy. During the implementation of the treatment, the template will be fixed on the patient's body surface by the clamping me...
