Abstract
A jaw position detection apparatus is configured to detect position information of at least one jaw moving in an arc, and includes a connecting component, a conversion mechanism, and a displacement sensor. The connecting component is fixed on a jaw. The conversion mechanism is connected to the connecting component, and the conversion mechanism is configured to convert an arc motion of the connecting component into a linear motion when the connecting component moves in an arc with the jaw. The displacement sensor is connected to the conversion mechanism, and configured to detect displacement information of the linear motion of the conversion mechanism.
Claims20
A jaw position detection apparatus, configured to detect position information of at least one jaw moving in an arc, the jaw position detection apparatus comprising:
- a connecting component fixed on a jaw;
- a conversion mechanism connected to the connecting component;
- wherein the conversion mechanism is configured to convert an arcuate motion of the connecting component into a linear motion when the connecting component moves in an arc with the jaw;
- and
- a displacement sensor connected to the conversion mechanism, and configured to detect displacement information of the linear motion of the conversion mechanism.
A medical accelerator treatment head, comprising at least one jaw, the at least one jaw configured to move in an arc, the medical accelerator treatment head further comprising a jaw position detection apparatus, wherein the jaw position detection apparatus includes:
- a connecting component, fixed on a jaw;
- a conversion mechanism, connected to the connecting component wherein the conversion mechanism is configured to convert an arcuate motion of the connecting component into a linear motion when the connecting component moves in an arc with the jaw;
- and
- a displacement sensor, connected to the conversion mechanism, and configured to detect displacement information of the linear motion of the conversion mechanism.
A medical accelerator treatment head, comprising:
- at least one jaw, configured to move in an arc;
- a jaw position detection apparatus;
- wherein the jaw position detection apparatus includes:
- a connecting component fixed on a jaw;
- a conversion mechanism connected to the connecting component;
- wherein the conversion mechanism is configured to convert an arcuate motion of the connecting component into a linear motion when the connecting component moves in an arc with the jaw;
- a displacement sensor, connected to the conversion mechanism, and configured to detect displacement information of the linear motion of the conversion mechanism;
- at least one motor;
- two arc gear rings;
- and
- a plurality of rotary gears, wherein two rotary gears are disposed at two sides of each jaw corresponding to the two arc gear rings, and the two rotary gears are matched with the two arc gear rings;
- and wherein the two rotary gear are configured to move in an arc along the two arc gear rings under driving of a motor.
