Description
Technical field
The invention relates to a kind of with Hall element wisdom detecting electricity startup rotation motor and its brake mechanism, espespecially a kind of assist physicians is in time performing boring operation, assist and initiatively judge to stop the best opportunity of cutter, reach and shorten operating time, stabilization procedure process, minimizing human error and reduce operation risk, and there is automatic buffer feed-disabling and the medical electric drill of the effect that stops operating.
Background technology
Along with the improvement of expanding economy, living material condition, Taiwan people's average life significantly improves, and the requirement of compatriots to quality of medical care is also more and more paid attention to.Except the research and development of related medical technology, designing and developing of armarium is also a very important problem.Particularly when carrying out surgical operation, many medical acts need to utilize the auxiliary of mechanical apparatus, and are ask the safety of operation with accurate, and the technology such as automatization, precision positioning of machinery, is also widely used in the exploitation of armarium.
In numerous armarium, electric drill is very general medical hand-held tool, often because of the injury of fracture, bone fracture this respect, usually need through surgical operation, use by electric drill and other medical machinery equipment of arranging in pairs or groups auxiliary and complete steel nail and fix knochenbruch object; The apparatus of current execution drilling into bone mainly can be divided into pneumatic brill, artificial hand brace and hand-held electric drill, wherein pneumatic brill is using gases at high pressure as advancing the surgical drill of strength, but because of operating room need possess gases at high pressure equipment and in recent years when operating room upgrades less hospital consider the pneumatic brill of employing; And the operational approach of the artificial hand brace free-hand rotation crank that is doctor, mechanism drives screw rod cause bit and move up and down, to reach the object of boring circle hole or cutting skull; The mode of operation of another hand-held electric drill then as electric drill, come keyhole direction and the amount of feeding by the free-hand support electric drill of doctor.This common a kind of particular electrical is drilled with in respect of one group of safety device, can closely cooperate when driving link (motor) bears pressure with the Passive part (drill bit) of similar clutch mechanism, drive running to carry out the behavior of brill skeleton, when drill bit drills skeleton, because the counteracting force no longer bearing skeleton makes driving link be separated with Passive part, electric drill is caused to shut down.
But whether these methods must rely on the abundant clinical experience of doctor individual and hand to feel to judge to bore in bone processes to pass through skeleton and manually to stop; If via lack the doctor of rich experiences perform time, even if there is the electric drill electric drill of above-mentioned specific safety device, careless slightlyly while passing through skeleton, also likely injure nervous tissue below skeleton or blood vessel.
Therefore, relevant dealer is had to carry out Improvement for this shortcoming, as patent of invention case, the open patent of invention case of No. CN102805656Ath, People's Republic of China's patent " medical electric drill ", the open patent of invention case of United States Patent (USP) No. US20120310247A1 " medical electric drill " of No. I418327th, TaiWan, China patent announcement " medical electric drill ", three discloses a kind of medical electric drill, and it comprises a drill bit, a microprocessor, a pressure sensing cells, a torsion sensing unit and a gravity-feed tank side unit.Drill bit is in order to a drilling into bone.Microprocessor is connected with drill bit signal, in order to calculate the shift length of drill bit.Pressure sensing cells in order to sense the pressure variety of drill bit, and provides a pressure change signal to give microprocessor.Torsion sensing unit in order to sense the torsion variable quantity of drill bit, and provides a torsion change signal to give microprocessor.Gravity sensing unit in order to sense the acceleration change amount of drill bit, and provides an acceleration voltage signal to give microprocessor.Wherein, microprocessor is according to pressure change signal and torsion change signal, and determine that drill bit is to a working hour of drilling into bone, microprocessor calculates the shift length of drill bit again according to the acceleration voltage signal in working hour.In addition, also can see that real-time message and LED and buzzer warn doctor from external screen in real time, prevent to cause unexpected injury to patient.
According to said structure, this medical electric drill contains drill bit, microprocessor, pressure sensing cells, torsion sensing unit and gravity-feed tank side unit, can pressure sensor and the change of knob profit when performing the operation, be supplied to microprocessor in real time to process, determine that drill bit is to the working hour of skeleton, microprocessor calculates the displacement of drill bit again according to acceleration voltage signal, though can learn that the drill bit of this medical electric drill carries out drilling depth real-time message for doctor in the very first time, but whether the drill bit that doctor must divert one's attention to control this medical electric drill proceeds boring action, careless slightly also likely in perform operation time still there is risk problem at any time, and urgently improved.
