Description
Technical field
Technical field of medical instruments is the utility model is related to, it particularly relates to a kind of pelvic osteotomy scroll saw guiding device.
Background technology
Pelvic osteotomy（Such as three osteotomy, Salter osteotomy, Periacetabular osteotomy）In, method that Iliac osteotomy is commonly used
It is to carry out osteotomy with scroll saw, current conventional method is that right angle forceps is close to bone from ilium inner panel and inserted towards rear using one
Enter, then pass around greater sciatic notch, when under direct-view right angle forceps point can be seen on the outside of greater sciatic notch, then make great efforts to open
Right angle forceps, common haemostatic clamp is passed into dehiscing for right angle forceps point with one by scroll saw, then clamps scroll saw with right angle forceps, and from interior
Right angle forceps is pulled out back in side, and scroll saw is taken out of；But problems with can be produced in practical operation：1st, conventional right angle forceps for radian compared with
Small and front end is shorter, for big-age-child it is difficult to quadrilateral around ischium, and exposes pincers point in outside, so as to transmit difficulty；
Even if the 2, very effort manifests right angle forceps point, when scroll saw is transmitted, because position is deeper, cause oozing of blood more and the visual field
It is fuzzy, while occur and transmit failure and operate situation for several times；3rd, scroll saw one end smoothly is clamped, when being extracted with scroll saw,
The crude edge of scroll saw is possible to injure the blood vessel below greater sciatic notch, once damage, hemostasis is extremely difficult.
The problem of in correlation technique, effective solution is not yet proposed at present.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of pelvic osteotomy scroll saw guiding device, no
It is only easy to operate and use, and avoid accidentally injuring blood vessel, so as to safe and reliable.
To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of pelvic osteotomy scroll saw guiding device, including the pincers sample handle formed by the caliper of two cross-articulations, the pincers
The end of body is respectively equipped with finger button, and the front end of the caliper is connected with hollow metal tube, the hollow metal tube include straight tube and
The semicircular bend pipe being connected with straight tube, the diameter of the straight tube is 6mm, and the semicircular diameter is 20mm, the straight tube
First through hole is provided with, the bend pipe is provided with the second through hole.
Further, it is connected with ratchet between described two calipers.
Further, the material of hollow metal tube is stainless steel.
The beneficial effects of the utility model：By semicircular hollow pipe, do not only reach easy to operate and use, and keep away
Exempt to accidentally injure blood vessel, so as to safe and reliable.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
In the required accompanying drawing used be briefly described, it should be apparent that, drawings in the following description are only of the present utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to this
A little accompanying drawings obtain other accompanying drawings.
Fig. 1 is according to a kind of one of structural representation of pelvic osteotomy scroll saw guiding device of the utility model embodiment；
Fig. 2 is two according to the structural representation of pelvic osteotomy scroll saw guiding device of the utility model embodiment a kind of.
In figure：1st, caliper；2nd, button is referred to；3rd, ratchet；4th, straight tube；5th, first through hole；6th, the second through hole；7th, semicircle bend pipe.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
As shown in Figure 1-2, a kind of pelvic osteotomy scroll saw guiding device according to the utility model embodiment, including by two
The pincers sample handle that the caliper 1 of individual cross-articulation is formed, the end of the caliper 1 are respectively equipped with finger button 2, the front end of the caliper 1
Hollow metal tube is connected with, the hollow metal tube includes straight tube 4 and the semicircular bend pipe being connected with straight tube 4, the straight tube 4
Diameter be 6mm, the semicircular diameter is 20mm, and the straight tube 4 is provided with first through hole 5, and the bend pipe 7 is provided with the
Two through holes 6.
In specific embodiment of the utility model, ratchet 3 is connected between described two calipers 1, according to doctor's finger
Length and operating habit adjustment caliper 1 between width.
In specific embodiment of the utility model, the material of hollow metal tube is stainless steel.
In order to facilitate above-mentioned technical proposal of the present utility model is understood, below by way of new to this practicality in specifically used mode
The above-mentioned technical proposal of type is described in detail.
It is first in operative process according to pelvic osteotomy scroll saw guiding device described in the utility model when specifically used
First, after exposing ilium inner panel, the semicircular bend pipe 7 in the front end of hollow metal tube is stretched into along bone wall, around greater sciatic notch,
Then, its front end can be looked at straight from outside；Then, scroll saw is penetrated in guiding device from the one end of inner side first through hole 5, from outside second
Through hole 6 passes；So that the neural blood vessel around scroll saw and greater sciatic notch can be with completely separated；Finally scroll saw is clamped from outside
One end, extracted from inner side by this guiding device, it is possible to proceed by osteotomy.
In summary, by means of above-mentioned technical proposal of the present utility model, by semicircular bend pipe 7, do not only reach just
In operation and use, and avoid accidentally injuring blood vessel, so as to safe and reliable.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
