Biplane ultrasound-guided radioactive seed implantation system for prostates

Abstract

The invention discloses a biplane ultrasound-guided radioactive seed implantation system for prostate. The system comprises a fixing seat, a supporting column, a universal joint arm, a fixing clip, astepper and an implantation template, wherein the stepper comprises a main frame, one end of the main frame is fixedly connected with a template supporting frame, and a scale ruler is arranged on theside wall of the main frame; a hollow lead screw of a coarse-fine adjustment mechanism is arranged in the main frame, and a first angle line is arranged on a rotating frame of a clamp; the template supporting frame is movably connected with the implantation template, and a second angle line and an angle value are arranged on the implantation template; the second angle line on the implantation template corresponds to the first angle line on the stepper, and the position of a puncture needle corresponding to a sagittal plane scanning image is quickly determined by adjusting the sagittal plane scanning angle of a biplane ultrasonic probe, so that operation time is shortened; coarse and fine adjustment units of the coarse-fine adjustment mechanism are coaxial, operation can be performed conveniently and quickly with only one hand during the operation, and operation efficiency is improved; the system is flexible and simple to operate, can be sterilized at high temperature, and is easy to disassemble and assemble and convenient to carry and store.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a dual-plane ultrasound-guided prostate radioactive particle implantation system. Background technique [0002] In recent years, due to the continuous increase in the incidence of prostate cancer in my country, many hospitals have implemented the technology of perineal permanent radioactive seed implantation for prostate cancer. Compared with other treatment methods (surgical resection and external radiotherapy), this method has the advantages of minimally invasive, good curative effect, simple operation, outpatient treatment and less side effects. However, to realize radioactive seed implantation surgery and ensure the accuracy of radioactive seed implantation, it is necessary to rely on implantation templates and three-dimensional treatment planning systems. The radioactive seed implantation system is the key factor for the accurate and smooth implantation ...

Problems solved by technology

However, the coarse adjustment handwheel and the fine adjustment handwheel of this device are separated on both sides of the main frame, which is inconvenient to operate during the operation; in the actual operation process, after the doctor inserts all the puncture needles into the tumor, he also needs to perform seed implantation on each puncture needle. Because there are multiple puncture needles on the implant template, how to determine whether a certain puncture needle is the one displayed on the sagittal plane scan image often requires a long operation time
