The method has the advantages that the drilling depth can be accurately controlled, the injury to the blood vessels, nerves and the like on the opposite side is avoided, the safety of the operation is improved, and the operation time is saved by completing the drilling depth measurement once.
Description
Technical Field
The utility model relates to a medical surgical instrument, in particular to a bone drill, in particular to an orthopedic drill with depth measurement and spacing.
Background
Clinically, the majority of patients with limb fracture adopt the internal fixation operation of cutting the reduction steel plate screw for treatment. The operation of fixing the steel plate screw in all needs to drill a hole on the bone by using a drill body, measure the depth of the drilled hole by using a depth finder and then screw a screw with a proper length for fixing. The current drill body does not have a precise limiting device and depth marking. If the depth of the stop is too short, the contralateral cortical bone is not drilled through, and if the depth of the stop is too long, the contralateral vessels, nerves and other important tissues are likely to be damaged. The depth measurement is carried out by using a depth finder after drilling, if the depth finder is inserted too deeply, injuries of blood vessels, nerves and the like on the opposite side are likely to be caused, the principle of the depth finder is that the cortex of the opposite side is hooked by a small hook and then measurement is carried out by reading a ruler, and the muscle or other tissues on the opposite side are likely to be hooked in the measurement process, so that the measurement is often inaccurate. Moreover, this first drilling and then sounding surgical approach results in prolonged surgical time.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model aims to provide an orthopedic operation drill body which can accurately limit, drill and measure depth at one time.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a take sounding and spacing orthopedics to bore, including boring body and stopper, its characterized in that: the drill body comprises a drill handle, an arc-shaped groove and a drill bit working part; the limiting stopper comprises a body, a steel ball, a fixed screw plug and a spring, the limiting stopper can be sleeved outside the drill body in a sliding mode, the steel ball is connected with the spring, the spring is connected with the fixed screw plug, and the steel ball can be movably clamped in the arc-shaped groove and is elastically connected with the arc-shaped groove.
The drill body is provided with scale marks of the depth of the drill bit.
The diameter of the steel ball is larger than the span of the arc-shaped groove.
When the drill bit bores through the bone cortex on one side of the long bone of four limbs and reaches the opposite side bone cortex, the length of the required screw can be known by the scale reading on the drill body and the thickness (3-4 mm) of the opposite side bone cortex, and meanwhile, the limiter slides to the corresponding position to limit, so that the drill bit just drills through the opposite side bone cortex and tissues such as opposite side blood vessels and nerves cannot be accidentally injured.
The utility model has the advantages that: the drilling depth can be accurately controlled, so that injuries to blood vessels, nerves and the like on the opposite side are avoided, the safety of the operation is improved, and the operation time is saved by completing the drilling depth measurement once.

Detailed Description
Referring to the drawings, the utility model relates to a take sounding and spacing orthopedics to bore, including boring body 1 and stopper 2, its characterized in that: the drill body 1 comprises a drill handle 11, an arc-shaped groove 12 and a drill bit working part 15; the limiter 2 comprises a body 26, a steel ball 27, a fixed screw plug 28 and a spring 29, the limiter 2 is slidably sleeved outside the drill body 1, the steel ball 27 is connected with the spring 29, the spring 29 is connected with the fixed screw plug 28, and the steel ball 27 is movably clamped in the arc-shaped groove 12 and elastically connected with the arc-shaped groove 12.
In the embodiment of the present invention:
the drill body 1 is provided with a scale 14 for the depth of the drill bit. The drilling depth can be observed and predicted conveniently.
The diameter of the steel ball 27 is larger than the span of the arc-shaped groove 12. The steel ball can roll flexibly.
When in use: the limiting stopper 2 is sleeved into the drill body 1, the length of the drill bit when the drill bit penetrates through the cortical bone on one side of the long bone and reaches the cortical bone on the opposite side and the thickness (3-4 mm) of the cortical bone measured before the operation are taken as the drilling depth (namely the length of the selected screw), the steel ball 27 is clamped in the arc-shaped groove 12 with the corresponding depth and is pressed tightly through the spring 29, the drilling depth of the drill bit can be known through the scale mark 14 of the drill bit depth, the drill handle 11 is connected with the electric drill, the electric drill is started to drill after the drilling point is determined, the limiting stopper 2 stops the drill bit from continuing to drill deeply after the drill bit is in place, and the vascular.
