Abstract
This utility model relates to a kind of double working modes bone drill, comprise drill bit, for the control system driving the motor of bit and control bit operation pattern, it is characterized in that, bit operation pattern comprises the first mode of operation and the second mode of operation, wherein said first mode of operation is used for rotation and the stopping of Non-follow control bone drill, and described second mode of operation is used for the rotation and the stopping that automatically controlling bone drill; In the second operation mode, control system acquisition stream through the decrease speed of the electric current of motor, when this decrease speed exceedes setting value, the automatic stall of driven by motor drill bit; Wherein, the setting of described setting value is depended on when drill bit drills skeleton electric current decrease speed instantaneously.This utility model possesses automatic mode and manual mode, can effectively avoid causing damage to blood vessel and nerve, and structure is simple, easy to use, has higher society and economic worth.
Description
Technical field
This utility model relates to a kind of armarium, is specifically related to a kind of double working modes bone drill.
Background technology
Bone drill is operating theater instruments conventional in orthopaedics, the mode of operation of existing bone drill is generally the stall of doctor's Non-follow control drill bit, this just makes brill deeply wayward, is easy to be difficult to when drilling skeleton immediately make drill bit stall, thus increases the risk damaging the blood vessel after drilling district and nerve.
Therefore, desirable to provide a kind of novel bone drill, automatically stall can be carried out drilling skeleton moment, effectively avoid causing additional injury to patient, and without the need to periosteum and muscle etc. are peeled off from fracture, thus shorten operating time, reduce the operation strength of doctor; Also wish that possess it possesses MANUAL CONTROL mode, to meet processing demands in some cases simultaneously simultaneously.
Summary of the invention
By Given this, the purpose of this utility model is to provide a kind of double working modes bone drill, automatically can either carry out stall, also possessing MANUAL CONTROL mode, for doctor's unrestricted choice simultaneously drilling skeleton moment.
The technical solution of the utility model is:
A kind of double working modes bone drill, comprise drill bit, for the control system driving the motor of bit and control bit operation pattern, it is characterized in that, bit operation pattern comprises the first mode of operation and the second mode of operation, wherein said first mode of operation is used for rotation and the stopping of Non-follow control bone drill, and described second mode of operation is used for the rotation and the stopping that automatically controlling bone drill; In the second operation mode, control system acquisition stream through the decrease speed of the electric current of motor, when this decrease speed exceedes setting value, the automatic stall of driven by motor drill bit; Wherein, the setting of described setting value is depended on when drill bit drills skeleton electric current decrease speed instantaneously.
Wherein, this control system comprises mode selection switch, for selecting described first mode of operation and the second mode of operation.
Wherein, this drill bit is changeable type drill bit.
Wherein, wherein this changeable type drill bit is taper bit, quincunx drill bit or drill bit of cultrating; And this changeable type drill bit is screwed onto on drilling rod.
Wherein, this double working modes bone drill also comprises illuminator, for providing illumination to drill bit direction.
Advantageous Effects of the present utility model is to possess automatic mode, drill skeleton moment can stall immediately, effectively to avoid causing damage to blood vessel and nerve, MANUAL CONTROL mode can also be selected as required to adapt to multiple actual demand simultaneously.This utility model structure is simple, easy to use, has higher society and economic worth.
Accompanying drawing explanation
Accompanying drawing 1 is the structured flowchart of double working modes bone drill of the present utility model.
Wherein 1 is drill bit, and 2 is motor, and 3 is control system, and 4 is illuminator, 31 mode selection switch.
Detailed description of the invention
As shown in Figure 1, a kind of double working modes bone drill, comprise drill bit 1, for the control system 3 driving the motor 2 of bit and control bit operation pattern, it is characterized in that, bit operation pattern comprises the first mode of operation and the second mode of operation, wherein said first mode of operation is used for rotation and the stopping of Non-follow control bone drill, and described second mode of operation is used for the rotation and the stopping that automatically controlling bone drill; In the second operation mode, control system acquisition stream through the decrease speed of the electric current of motor, when this decrease speed exceedes setting value, the automatic stall of driven by motor drill bit; Wherein, the setting of described setting value is depended on when drill bit drills skeleton electric current decrease speed instantaneously.
In use procedure, when in the face of uncomplicated situation, user can only select the first mode of operation to complete whole boring procedure; When in the face of comparatively complex situations, user can first adopt the first mode of operation to hole, and when after drilling skeleton hollow area or when being about to drill whole piece skeleton, user the second mode of operation of converting is holed, thus effectively reduces the injury risk to sufferer.
Wherein, this control system comprises mode selection switch 31, for selecting described first mode of operation and the second mode of operation.Mode selection switch 31 can be two be separated switches to select the first mode of operation and the second mode of operation respectively, also can be a switch, by selecting the first mode of operation and the second mode of operation by the number of times compressed switch or zones of different.
Wherein, this drill bit is changeable type drill bit, requires and tackle different bone types to adapt to different bore sizes; More specifically, this changeable type drill bit is taper bit, quincunx drill bit or drill bit of cultrating.
Changeable type drill bit can by being spirally connected, grafting or bolt mode be arranged in drilling rod (not shown), when employing is spirally connected, the screw connection manner of drill bit and drilling rod should make when bit, the power that drill bit is tightened.
This bone drill can also comprise illuminator 4, for providing illumination to drill bit direction; More specifically, illuminator can be arranged on drilling rod.Illuminator 4 can use white LED light source.
Should understand, specific embodiment given by this utility model is be described spirit of the present utility model, instead of in order to limit the scope of its request protection.When not departing from the spirit and scope of the present utility model limited by appended claim, those skilled in the art can carry out various distortion and improvement to this utility model, and these distortion and improvement also should be subject to the protection of this utility model patent.
Claims (5)
