Embodiment Construction

[0020] Further explanation below in conjunction with accompanying drawing and specific embodiment:

[0021] According to research, after the drill bit 3 drills and penetrates the bone tissue during the operation of the bone drill motor, the torque generated by the rotating shaft of the bone drill motor due to resistance is obviously different. For the operator, there is an obvious sense of loss at the moment of drilling. The characterization of the torque generated by this feeling of falling on the shaft of the bone drill motor is a step from large to small torque.

[0022] Therefore, if figure 2 As shown, an annular metal member 7 is set on the body of the bone drill motor, and four strain gauges 8 are respectively arranged on the annular metal member 7 along the axis ± 45° direction. The strain gauge 8 adopts a high-temperature strain gauge, which can meet high temperature Autoclaving required. Four strain gauges 8 are located on the same cross-section of the annular met...

Abstract

The invention discloses an intelligent bone drill. A common bone drill motor is provided with a strain torque sensor, a revolution speed transducer or a pressure sensor; the bone drill motor is further provided with an embedded intelligent control module that receives an induced signal collected by the sensor and judges the same to control the bone drill motor. The invention further discloses a control method of the intelligent bone drill. Beneficial effects of the invention lie in that a base body of the common bone drill motor is provided with a revolution speed transducer composed of a hall sensor and a metal reading code disk, a torque sensor and a pressure sensor to measure and display revolution speed, torque and pressure of the drill realtime, which realizes judgment of whether the drill pierces the bone tissue and control of automatic stop and reversion; the bone drill motor is provided with an ultrasonic transducer that can measures drill depth of the drill accurately. The improvement can provide effective data during operation for operator and reliable protection realtime.

Description

technical field [0001] The present invention relates to a medical device, more precisely to an intelligent bone drill and a control method thereof. technical background [0002] Bone drill electric drill (abbreviated as bone drill) is one of the commonly used surgical instruments in orthopedics. However, the safety performance of existing bone drills is not easy to guarantee, which is mainly reflected in that the depth of drilling, the speed of the electric drill, the control of starting and stopping, etc. are all controlled by the operator, and it is often "relative" for the doctor to choose to cut the skin on one side. "Safe side" is the side with fewer important blood vessels and nerves or the side where the operation is convenient, while the other side of the bone has important blood vessels and nerves. The existing orthopedic electro-rotary rotor rotates at high speed after passing through the contralateral bone cortex , It is not easy to control, and it hurts blood ve...
