Intelligent bone drill and control method thereof

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...

AI Technical Summary

Problems solved by technology

[0003] 1. Increased operation time and work intensity;

[0004] 2. Increased the degree of injury at the fracture end, peeled off the periosteum at both ends of the fracture, reduced or stopped the blood supply of the fracture end, resulting in difficulty in fracture healing, delayed or nonunion, and increased bed rest time and economic burden of the patient;

[0006] After each drilling, it is necessary to measure the depth with a measuring ruler, which increases the operation time and has no corresponding instructions and protection measures, so there is a large medical safety hazard
