Abstract

The invention provides a TRUS image navigation multichannel prostate close-range radioactive seed implantation robot and relates to the field of medical apparatus and instruments for the purpose of overcoming the defects of a manual image navigation prostate close-range radioactive seed implantation operation. The TRUS image navigation multichannel prostate close-range radioactive seed implantation robot is composed of a rack, a bidirectional movement mechanism, a position adjustment mechanism, an electric seed implantation mechanism, a multichannel puncture mechanism and a TRUS image navigation mechanism. The TRUS image navigation multichannel prostate close-range radioactive seed implantation robot is structurally characterized in that through cooperative use of the bidirectional movement mechanism and the position adjustment mechanism, an outer needle of the electric seed implantation mechanism can be adjusted to a target height (primary location); when the bidirectional movement mechanism is combined with the multichannel puncture mechanism, a prostate tumor area puncture needle can be arranged, and the prostate can be fixed; when the electric seed implantation mechanism is combined with the TRUS image navigation mechanism, closed-loop control over the acupuncture needle position can be realized through image feedback, and the precision of seed implantation can be improved.

Description

technical field [0001] The invention and the field of medical devices belong to the interdisciplinary disciplines of medicine, machinery and automation, and specifically relate to a TRUS image navigation multi-channel prostate close-range radioactive particle implantation robot. Background technique [0002] Brachytherapy seed implantation has the characteristics of strong targeting, no side effects, less trauma, and definite curative effect. It has become a standard method for the treatment of early prostate cancer at home and abroad. Traditional radiotherapy is guided by manual ultrasound, with the help of a guide plate fixed on the ultrasound bracket, clinicians use a manual particle implanter to inject 20 to 120 nickel-titanium alloy-wrapped 125I (144Gy) / 103Pd (120Gy) Particles are implanted into the target area, and γ-rays are irradiated continuously at low doses to kill tumor cells. At present, most of the particle implanters at home and abroad are single-channel and ...
