Abstract

The invention discloses a friction wheel TRUS image navigation driving device and method to overcome the defect of existing manual TRUS image navigation devices and relates to the field of medical apparatus. A friction wheel mechanism is used for achieving linear motion and rotation motion of an ultrasonic probe, so that the ultrasonic probe is simple and compact in driving structure; a parallelogram mechanism is used, and the friction wheel mechanism can form a telecentric mechanism, so that when the ultrasonic probe enters a rectum inlet, yaw, pitch and rolling postures of the ultrasonic probe can be adjusted at fixed points.

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 friction wheel TRUS image navigation drive device and method. 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 wrap 20 to 120 nickel-titanium alloys. 125 I (144Gy) / 103 Pd (120Gy) particles were implanted into the target area, and the tumor cells were killed by continuous low-dose radiation of gamma rays. [0003] Real-time transrectal ultrasound-guided radioactive particle brachytherapy for the prostate: first, the sonog...
