Abstract
The invention discloses a kirschner wire take-out locator which comprises a locator shell, an iron core, a coil, a sliding resistor, a battery and a switch. The locator shell is in a cylindrical shape. A conical end is arranged at one end of the locator shell, and the other end of the locator shell is a flat end. The switch is arranged at the flat end of the locator shell. The iron core and the battery are arranged in the locator shell. One end of the iron core penetrates through and extends out of the conical end of the locator shell. The end, extending out of the locator shell, of the iron core is in a conical shape. The end, located in the locator shell, of the iron core is sleeved with the coil. The sliding resistor is arranged on the inner side wall of the locator shell and comprises a resistor body and a slide block arranged on the resistor in a slidable mode. A slide groove is formed in the position, opposite to the slide block on the sliding resistor, on the locator shell. The coil, the sliding resistor, the battery and the switch are connected into a serial-connection circuit through wires. The circuit is controlled by the switch to be powered on and powered off. By means of the mode, the position of a kirschner wire can be precisely and rapidly located.
Description
Technical field
The present invention relates to Kirschner wire and take out field, particularly relate to a kind of Kirschner wire and take out localizer.
Background technology
In bone surgery, internal fixation Kel's needle for fracture is difficult to once take out, and often needs second operation to take out; Localizer is taken out owing to there is no special Kirschner wire at present, reserve in skin surface or subcutaneous the length that can touch so Kirschner wire tail end can be stayed during fracture fixation, therefore pin site infection or tractive subcutaneous tissue may be caused to affect functional rehabilitation, simultaneously for the Kirschner wire that position is darker, often need patient's spended time to go to find Kirschner wire tail end, also need operative incision to extend if desired.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Kirschner wire and takes out localizer, Kirschner wire position can be navigated to accurately, reserving in skin surface or subcutaneous the length that can touch without the need to being stayed by Kirschner wire tail end, can also operating time be saved, avoid prolonged incison; Its structure is simple, easy to operate, quick.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of Kirschner wire to take out localizer, comprising: localizer housing, iron core, coil, swept resistance, battery and switch; Described localizer housing is column type, and localizer shell one end is provided with conical end, and the localizer housing other end is flush end; Described switch-linear hybrid is on the flush end of described localizer housing; Described iron core and battery are all arranged on described localizer enclosure interior, and one end of iron core is stretched out through the conical end of localizer housing, and one end that iron core stretches out localizer housing be coniform, and one end that iron core is in localizer enclosure interior is overlapped described coil; The medial wall of described localizer housing is provided with swept resistance, and swept resistance comprises resistance and is slidably arranged on ohmically slide block, and on localizer housing, the position of relative sliding resistance top shoe has chute, and slide block can slide in chute; Described coil, swept resistance, battery and switch connect into a series circuit by wire, the break-make of ON-OFF control circuit.
Preferably, on described iron core, the one end at opposed coil place is fixed with round platform, and round platform axis overlaps with iron mandrel line position, and the diameter of round platform is greater than the diameter of coil.
Preferably, described switch is press button; Described battery is rechargeable battery.
The invention has the beneficial effects as follows: the present invention accurately can navigate to Kirschner wire position fast.
Accompanying drawing explanation
Fig. 1 is the perspective structure schematic diagram that a kind of Kirschner wire of the present invention takes out localizer one preferred embodiment;
Fig. 2 is the operation principle schematic diagram that a kind of Kirschner wire of the present invention takes out localizer.
In accompanying drawing, the labelling of each parts is as follows: 1, localizer housing; 2, ferrum core; 3, coil; 4, swept resistance; 5, rechargeable battery; 6, press button.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of Kirschner wire takes out localizer, comprising: localizer housing 1, iron core 2, coil 3, swept resistance 4, rechargeable battery 5 and press button 6; Described localizer housing 1 is in column type, and localizer housing 1 one end is provided with conical end, and localizer housing 1 other end is flush end; Can conveniently hold, it is simple to operate, easy to make.Described press button 6 is arranged on the flush end of described localizer housing 1; It is inner that described iron core 2 and rechargeable battery 5 are all arranged on described localizer housing 1, one end of iron core 2 is stretched out through the conical end of localizer housing 1, one end that iron core 2 stretches out localizer housing 1 is coniform, can reduce the position range of the Kirschner wire detected, can position accurately; On one end that iron core 2 is in localizer housing 1 inside, cover has described coil 3, iron core 2 can be made to produce magnetic force, position at skin surface to Kirschner wire tail end; On described iron core 2, the one end at opposed coil 3 place is fixed with round platform, and round platform axis overlaps with iron core 2 axial location, and the diameter of round platform is greater than the diameter of coil 3, and coil 3 can be prevented from landing iron core 2, the magnetic force that after ensureing energising, iron core 2 produces.The medial wall of described localizer housing 1 is provided with swept resistance 4, and swept resistance 4 comprises resistance and is slidably arranged on ohmically slide block, and on localizer housing 1, the position of relative sliding resistance 4 top shoe has chute, and slide block can slide in chute; Iron core 2 can be regulated to produce the size of magnetic force by sliding slider, namely be that Kirschner wire position is comparatively dark, also can detect Kirschner wire position fast.Described coil 3, swept resistance 4, rechargeable battery 5 and press button 6 connect into a series circuit by wire, the break-make of press button 6 control circuit; Kirschner wire can be used more easily to take out localizer.
The present invention can navigate to Kirschner wire position accurately, reserving the length that can touch, can also save operating time, avoid prolonged incison without the need to being stayed by Kirschner wire tail end in skin surface or subcutaneous; Its structure is simple, easy to operate, quick.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
