Abstract
The utility model discloses a Kirschner wire which comprises a needle tip and a needle rod, and is characterized in that the needle rod is provided with threads, and the tail of the needle rod is connected with a limiting snap ring by the threads. In the utility model, the needle rod is provided with the threads, so as to well fix the Kirschner wire in sclerotin, and achieve the effect of preventing moving or sliding. In addition, the needle rod is connected with the limiting snap ring by the threads, after the Kirschner wire is placed in an appropriate position, the Kirschner wire is shorn off at a position about 2-3 rnm outside the limiting snap ring, and the needle end can be buried inside a human body, so as to not only prevent the Kirschner wire from moving towards the interior of human tissue along the direction of a long axis, but also avoid strenuous bending operation with poor accuracy. Therefore, the Kirschner wire can ensure smooth bone traction operation, reduce the suffering of patients with bone fracture, and reduce the working intensity of medical staff.
Description
Technical field
This utility model relates to a kind of orthopaedic medical treatment utensil, specifically, relates to a kind of Kirschner wire.
Background technology
Kirschner wire is a kind of medical apparatus and instruments commonly used in bone surgery, and internal fixation and bone traction operation is usually used in fracturing.The shank of existing Kirschner wire is slick, and when doing the bone traction, needle body tends to move in bone or slide, and particularly the sclerotin of middle-older patient is more loose, and this mobile meeting is apparent in view.Needle body also easily slided when the long-term bone of between twenty and fifty patient drew.So, be easy to cause local infection and pressure ulcer, cause the patient can not tolerate the bone traction, seriously influenced carrying out smoothly and effect of traction operation.
In addition, existing Kirschner wire is a straight rod type, the Kirschner wire of this structure has the possibility that moves along long axis direction in tissue, can only move with the method restrictive axial of tail end bending at present, if the tail end of bending stay in external have local skin infect, with medicated clothing friction pain uncomfortable and scratch medicated clothing may.Bury in body then because " L " type backshank of bending stimulates local soft tissue to cause the pain malaise symptoms.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defective, provides a kind of avoid appearing in the bone to move or slide and along the phenomenon that long axis direction moves, guarantee the Kirschner wire that bone traction operation can be carried out smoothly in tissue.
For addressing the above problem, the technical scheme that this utility model adopted is:
A kind of Kirschner wire comprises needle point and shank, it is characterized in that: described shank is provided with screw thread; The tailing screw flight of shank is connected with spacing snap ring.
Owing to adopted technique scheme, compared with prior art, shank of the present utility model is provided with screw thread, can make Kirschner wire well fixing in sclerotin, plays preventing effect mobile or that slide.In addition, spacing snap ring has been threaded on the shank, after Kirschner wire inserted correct position, about 2～3rnm cuts off Kirschner wire in the place outside spacing snap ring, backshank can bury in body, can prevent that like this Kirschner wire from moving in tissue along long axis direction, can avoid again requiring great effort, the bending operation of poor accuracy.Thereby this utility model can guarantee that bone draws operation and carries out smoothly, simultaneously, alleviates the misery of fracture patient, reduces medical worker's working strength.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the present utility model.
Among the figure: the 1-needle point; The 2-shank; The spacing snap ring of 3-.
The specific embodiment
Embodiment:
A kind of Kirschner wire as shown in drawings, comprises needle point 1 and shank 2.Described shank 2 is provided with screw thread; The tailing screw flight of shank 2 is connected with spacing snap ring 3.
Claims (1)
1. a Kirschner wire comprises needle point (1) and shank (2), and it is characterized in that: described shank (2) is provided with screw thread; The tailing screw flight of shank (2) is connected with spacing snap ring (3).
