Therapeutic head efficient anti-collision mechanism

Abstract

The invention discloses a therapeutic head efficient anti-collision mechanism. The therapeutic head efficient anti-collision mechanism comprises a mounting substrate, anti-collision checking ring, a switch assembly, a horizontal pushing assembly and a vertical pushing assembly; the mounting substrate is an annular flat plate; the anti-collision checking ring is of a circular cover-shaped structure; a concentric circular hole is machined in the bottom surface of the anti-collision checking ring; the diameter of the circular hole is greater than the inner diameter of the mounting substrate; the mounting substrate is movably connected with the anti-collision checking ring through the horizontal pushing assembly and the vertical pushing assembly; the switch assembly is fixedly connected onto the mounting substrate; and the horizontal and longitudinal displacement of the anti-collision checking ring can both trigger the switch assembly. The therapeutic head efficient anti-collision mechanism can transmit signals to a device control system when a therapeutic head is squeezed.

Description

technical field [0001] The invention belongs to the technical field of safety control, and in particular relates to a high-efficiency anti-collision mechanism for a treatment head. Background technique [0002] During the treatment process, the accelerator needs to perform radiotherapy on the patient's tumor at different angles, so the treatment head rotates with the accelerator frame to the angle position required for treatment. Since the tumor may be in different positions in the patient's body, when the rotating treatment bed moves the patient's body When a tumor is placed within the range of the radiation therapy beam, the treatment head may touch or squeeze the treatment bed or the patient's body, causing death or injury to the patient or damage to the equipment. Contents of the invention [0003] In view of this, the present invention provides an efficient anti-collision mechanism for the treatment head, which can send a signal to the equipment control system when th...
