A kind of kirschner pin location sinkerTechnical field
The present invention relates to location, kirschner pin direction and depth measurement instrument field, particularly relate to a kind of kirschner pin location sinker.
Background technology
The conventional Kirschner wire fixation of present hand and foot fracture point, kirschner stylus printer enters direction and depth of drive thereof, entirely with the clinical experience of patient, usually squeezes into direction and is unsatisfied with, and depth of drive is crossed long or too short, certainly will cause repeated multiple times squeezing into; Kirschner stylus printer entered length can cause offside skin swash invite, shouting pain, affect postoperative function exercise, squeeze into too short postoperative fracture and fix insecure.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of kirschner pin location sinker, opponent's foot fractures adopts this kirschner pin location sinker temporarily fixing simultaneously to the direction basic confirmation of kirschner pin after resetting, depth of drive can preoperative be measured, kirschner pin is squeezed into after measuring, can be effectively fixing to fracture, depth of drive is accurate, makes operation technique more easily easy, shortens operating time.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provides a kind of kirschner pin location sinker, comprising: left clamp handle, right clamp handle, left pincers head, right pincers head, fixed jaw, aiming sleeve, tooth bar and scale; Described left pincers head is connected in left clamp handle, and right pincers head is connected in right clamp handle, and left clamp handle and right clamp handle are connected by retaining screw and left clamp handle and right clamp handle can relatively rotate; Described fixed jaw is fixed on right pincers crown end, and described aiming sleeve is fixed on left pincers crown end, and aims at sleeve setting corresponding to fixed jaw; Described tooth bar and scale are mutually corresponding to be arranged, and tooth bar is fixed on inside left clamp handle, and scale is fixed on inside right clamp handle.
Preferably, described aiming sleeve axis is equal to the vertical range of retaining screw with scale to the vertical range of retaining screw.
The invention has the beneficial effects as follows: the present invention can realize location, Kirschner wire fixation direction, and kirschner stylus printer enters depth survey, effectively prevent kirschner pin direction of travel from partially bending and to pass offside cortex too much.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram during sinker using state of the present invention's a kind of kirschner pin location.
In accompanying drawing, the mark of each parts is as follows: 1, left clamp handle; 2, right clamp handle; 3, left pincers head; 4, right pincers head; 5, fixed jaw; 6, sleeve is aimed at; 7, tooth bar; 8, scale.
Embodiment
Below in conjunction with accompanying drawing, the better embodiment of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made more explicit defining.
Referring to Fig. 1, the embodiment of the present invention comprises:
A kind of kirschner pin location sinker, comprising: left clamp handle 1, right clamp handle 2, left pincers 3, right pincers 4, fixed jaw 5, aiming sleeve 6, tooth bar 7 and scale 8; Described left pincers 3 are connected in left clamp handle 1, and right pincers 4 are connected in right clamp handle 2, and left clamp handle 1 and right clamp handle 2 are connected by retaining screw and left clamp handle and right clamp handle can relatively rotate; Described fixed jaw 5 is fixed on right pincers 4 top, and described aiming sleeve 6 is fixed on left pincers 3 top, and aims at sleeve 6 setting corresponding to fixed jaw 5; Described tooth bar 7 and scale 8 are mutually corresponding to be arranged, and tooth bar 7 is fixed on inside left clamp handle 1, and scale 8 is fixed on inside right clamp handle 2; Aim at sleeve axis equal to the vertical range of retaining screw with scale to the vertical range of retaining screw; As shown in fig. 1, the reading of tooth bar and scale is a, and the most advanced and sophisticated distance a ' to aiming at sleeve tail end of fixed jaw equals a, and b is the depth of drive of kirschner pin in bone, it is known that aiming at the length c of sleeve, a '=b+c, then can calculate kirschner pin depth of drive b. Aiming at sleeve is kirschner needle cannula, locates use as kirschner pin direction, and tooth bar and scale, can accurately measure sleeve tail to fixed jaw length, i.e. kirschner pin length, can obviously shorten operating time, once successfully fix, it is to increase procedure efficiency.
The foregoing is only embodiments of the invention; not thereby the patent scope of the present invention is limited; every equivalent structure utilizing specification sheets of the present invention and accompanying drawing content to do, or directly or indirectly it is used in other relevant technical fields, all it is included in the scope of patent protection of the present invention with reason.
