Surgical robot system and operation method for radioactive particle interventional therapy of tumor

Abstract

The invention discloses a surgical robot system for radioactive seed interventional therapy of tumors and an operating method and relates to the field of medical instruments. A host is connected with a display screen and connected with a CT (computed tomography) machine and a robot arm; multiple rows of radioactive seed injection guiding holes are distributed in an injector guide template side by side, and the injector guide template is clamped by a six-DOF (degree of freedom) robot arm; a robot manual operation panel is connected with the robot arm, and the robot arm is fixed on the edge of a CT bed, can slide along the edge of the CT bed and can enter the inside of the CT machine along with the CT bed; after the operation robot host acquires information of the position required to be treated according to a CT image, the posture of a positioning probe on the guide template at the tail end of the robot arm is judged; the system gives an instruction to move the robot arm, the guide template is placed in the position where radioactive seeds are required to be injected, and an injector punctures the tumor part along the injection guiding holes in the guide template, injects the radioactive seeds and controls the injection amount according to a diagnosis result.

Description

technical field [0001] The invention relates to the field of medical instruments. Specifically, it relates to a surgical robot system and an operation method for radioactive particle interventional therapy of tumors. Background technique [0002] Radiation particle interventional therapy is a method of "internal radiotherapy" to treat tumors. It uses its short-distance radiotherapy effect to kill tumor cells, thereby avoiding the radiotherapy damage of "external radiotherapy" to normal tissues around the tumor. [0003] The current radioactive particle interventional tumor surgery platform includes a manual positioning platform, treatment planning system (Treatment planning System, TPS), 3D printing guide template system, radiotherapy phantom water tank heating system and other key parts. [0004] The main problem that existing operation platform exists is: (1) expensive. The imported multi-degree-of-freedom manual positioning platform is expensive; the positioning model i...

AI Technical Summary

Problems solved by technology

[0004] The main problem that existing operating platform exists is: (1) expensive

The imported multi-degree-of-freedom manual positioning platform is expensive; the positioning model is formed by 3D printing, and the cost is relatively high

(2) Long operation time

Patients need to wait for the 3D printing positioning model after the preoperative examination, which takes a long time and is inefficient

(3) Positioning is difficult

Preoperative examination and surgical treatment are not carried out at the same time, even if the positioning model is used, it involves complex operations and large errors in secondary positioning

(4) Manual operation is inconvenient

The current manual positioning platform, the operation is very cumbersome, the positioning is slow, the workload is heavy, and there are also problems of large manual operation errors

(5) The injection of radioactive particles and stent treatment equipment also have problems such as inaccurate fixation and large trauma to the lumen

(6) The heating system of the radiotherapy phantom water tank is bulky, inconvenient to operate, high in energy consumption, low in efficiency and poor in sanitation
