Radioactive particle implantation equipment guided by ultrasound bronchoscope

Abstract

The invention relates to the field of a medical instrument, in particular to radioactive particle implantation equipment guided by an ultrasound bronchoscope. The equipment comprises a puncture part and a handle part in mutual connection, wherein the puncture part comprises a puncture part hose and a puncture needle penetrated inside the puncture part hose, a particle passage is arranged inside the puncture needle in the axial direction for placing radioactive particles, the handle part comprises a puncture part hose pushing handle, a puncture needle pushing handle and a radioactive particle pushing rod, the puncture part hose pushing handle is connected with the tail end of the puncture part hose pushing handle, the puncture needle pushing handle is connected with the tail end of the puncture needle, the radioactive particle pushing rod is connected with a pushing guide wire, and the pushing guide wire passes through the puncture part hose and extends to the inside of the particle passage. The radioactive particle implantation equipment has the advantages that particles do not need to be pushed from the body outside, the walking path of the particles in the pushing process is short, and the precision of reaching the target position is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for implanting radioactive particles under the guidance of an ultrasound bronchoscope. Background technique [0002] In current clinical practice, the conservative treatment effect on many mediastinal primary tumors that have lost the chance of surgical resection and mediastinal metastatic tumors from lung and esophageal cancer is poor. The implantation of radioactive seeds can prolong the survival of a considerable part of these patients and delay the progression of the disease. At present, the conventional way of radioactive seed implantation is CT-guided percutaneous puncture implantation, but this technique requires CT guidance, and the lung often moves the target area with breathing movement, which cannot achieve real-time performance, thus affecting radioactive seed implantation. input accuracy.
