Description

Medical bone drill with angle display and torque monitoring functions

Technical Field

The utility model belongs to the field of medical appliances, specific medical bone drill from taking angle demonstration and moment of torsion monitor function that says so.

Background

At present when orthopedics doctor carries out wound drilling operation to the patient, traditional approach only relies on doctor's naked eye and feels and judges whether the drill bit position is beaten just, whether beat to open, such traditional approach has certain operational risk, if the relative position of drilling has the deviation, then the direction of installing coaptation self-tapping screw on next step will have the deviation, can influence the firm degree of screw installation, if the moment of torsion during drilling exceeds the working torque scope, appear drilling bit card dead easily or bore the adverse effect that the through-hole back drill bit wounded and other tissues, the bone drill of taking moment of torsion monitoring function has slowly appeared in the market, if the mandate number is: the bone drill of CN 203234784U, however, is known from the published literature that it is only provided with a torque monitoring function, and it is not ideal to monitor whether the angle of the drill hole deviates, and the display screen of the bone drill is not arranged on the bone drill body, and the doctor needs to pay attention to the positions of the bone drill and the drill hole during the operation, so it is difficult to shift the view to the display screen on one side, and it is obviously inconvenient to arrange the display screen outside the bone drill body.

SUMMERY OF THE UTILITY MODEL

In view of the defects existing in the prior medical bone drill, the utility model aims to solve the technical problems that: the medical bone drill with the angle display and torque monitoring functions is provided, and meanwhile, the medical bone drill is convenient to view the angle display and torque monitoring values.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a medical bone drill with angle display and torque monitoring functions comprises a bone drill body and a battery box, wherein the bone drill body is composed of a horizontal knob and a handle vertically fixed on the knob, one side of the knob is fixed with a quick drill chuck, the other side of the knob is sealed by a rear end cover, an initial positioning button is arranged on the rear end cover, a driver and a motor are arranged in the handle, a torque inclination angle sensor and a Bluetooth serial port module are further arranged in the handle at the lower end of the driver, the torque inclination angle sensor and the Bluetooth serial port module are connected through a flat cable, the initial positioning button is connected with the Bluetooth serial port module through a lead, the battery box is movably fixed at the bottom of the handle, a display screen is arranged on the vertical surface of one side of the battery box opposite to the rear end cover, a battery pack is arranged in the battery box, a Bluetooth data receiver, a single, the data acquisition card is connected with the single chip microcomputer through a flat cable, the single chip microcomputer is connected with the display screen through the flat cable, and the Bluetooth serial port module and the Bluetooth data receiver transmit data in a wireless mode.

Compared with the prior art, the utility model has the advantages of: the drilling angle is displayed in real time, and meanwhile, the display screen is arranged on the battery box, so that the numerical value can be conveniently watched during drilling.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "bottom", "top", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1

Referring to fig. 1, the medical bone drill with angle display and torque monitoring functions provided in this embodiment includes a bone drill body, a fast-connection drill chuck, a rear end cap, an initial positioning button, a battery box, a display screen, a data acquisition card, a single chip, a bluetooth serial port module, a bluetooth data receiver and a torque tilt sensor 12, the bone drill body is composed of a horizontal knob and a handle vertically fixed on the knob, the fast-connection drill chuck is fixed at the front end of the knob, the rear end cap seals the rear end of the knob, the initial positioning button 7 is fixed on the rear end cap, a driver 11 and a motor 10 are fixed in the handle of the bone drill body, the torque tilt sensor 12 and the bluetooth serial port module are located at the lower end of the driver 11, and the initial positioning button on the rear end cap is connected with the bluetooth serial port module through a flat cable, the battery box is a rectangular plastic shell, and the upper end of the plastic shell, the display screen installing port is formed in the right side wall of the battery box, the display screen is located in the display screen installing port, a battery pack is fixed in the battery box, a Bluetooth data receiver, a single chip microcomputer and a data acquisition card are arranged inside the battery pack, the Bluetooth data receiver is connected with the data acquisition card through a flat cable, the data acquisition card is connected with the single chip microcomputer through the flat cable, and the single chip microcomputer is connected with the display screen through the flat cable.
