Abstract
The utility model relates to a finger-ring type arch-shaped aiming device which comprises a fixing cylinder sleeved with a drill sleeve, and is characterized in that a sighting device is arranged on the fixing cylinder; and by adopting the above technical scheme, the finger-ring type arch-shaped aiming device has the advantages that firstly, manual aiming is not required, and the accuracy is high; secondly, the index finger and the middle finger of the left hand can clamp a fixing seat very conveniently, the stability is strong, and aiming is convenient; and thirdly, stretching, punching and bolting can be finished through aiming without human assistance, and errors are avoided.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates to the arc sight of a kind of finger ring type specifically.
Background technology
In comminuted fracture or have in the internal fixation operation of fracture of big bone, often need be at a side nailing bone fixation piece or an osteocomma that has soft tissue to hide.At present, beating the lag screw aspect from the offside of osteocomma also needs artificial aiming, and what rely on is clinicist's experience, and error is bigger, causes iatrogenic secondary damage after the error, and the bone hole of staying after the failure is the hidden danger that causes refracture repeatedly.The major axis that when using the device for taking out broken nail rotation to get the broken nail stump, need make extractor is in concluding that the stump major axis overlaps, and manual work is difficult to accomplish.Usually making the stump of broken nail that secondary breakdown takes place again, make broken nail taking-up back aperture excessive after proofreading and correct repeatedly, is that the maximum reason that internal fixation takes out the back refracture takes place.
The utility model content
The problem that this utility model will solve is to above problem, and a kind of arc sight of finger ring type accurate, easy to use that punches is provided.
For addressing the above problem, the technical scheme that this utility model adopted is:
The arc sight of finger ring type comprises stationary magazine creel, and fixing barrel casing is connected to drill holder, it is characterized in that: said stationary magazine creel is provided with sighting device.
As a kind of improvement:
Said sighting device comprises the holder that is fixedly connected with stationary magazine creel, and holder is connected with vane, and vane is provided with sight hole away from an end of holder, the centrage of said sight hole and the central lines of stationary magazine creel.
Said holder is an arc.
The both sides of said holder are fixed with finger ring.
As further improvement:
Said vane is an arc.
Said vane and holder are pegged graft, and are provided with the adjusting bolt between vane and the holder.
This utility model is taked above technical scheme, has the following advantages: 1, need not artificial aiming, accuracy is high; 2, left index finger, middle finger can be clamped holder very easily, and stability is strong, are convenient to aiming; 3, scalable, punch, beat screw and all can under aiming, accomplish, do not need manual work to assist, avoid error.
Below in conjunction with accompanying drawing and embodiment this utility model is described further.
