Abstract
The invention discloses a multi-function guider for inter-articular fracture, which mainly consists of a main support arm, a guide arm and a fixed rod, wherein both the main support arm and the guide arm are arc-shaped, which can stretch along an arc direction when being sleeved and combined are temporarily fixed via a knob. The front end of the guide arm forms a fixed head pointing to the center of a circle when being bent inwards, the fixed rod can be pulled and arranged on the main support arm radially and flexibly and is fixed via the knob. The front end of the fixed rod forms another fixed head pointing to the center of a circle. The position where the main support arm is sleeved with the guide arm is provided with a plurality of radial through guide holes. The multi-function guider can fix fractured blocks temporarily, defines the direction of a temporarily fixed kirschner wire and the direction of a screw to fix the fractured block without enlarging a notch, and a screw for fixation can be screwed in from a screw guide pin conveniently, thus the multi-function guider is very convenient and practical.
Description
Technical field
The present invention relates to bone surgery set, exactly is intra-articular fracture guide apparatus.
Background technology
At present, when the reduction of the fracture and internal fixation are carried out in baroque intra-articular fracture position, often need accurately to determine that whether screw or other internal fixation have carried out fixedly securing to fracture and whether fixed direction is reasonable, to satisfy the theory of " Wicresoft " treatment as far as possible, otherwise bad repeatedly is fixing, can lower screw to fixation of fractures intensity, but existing various orthopedic medical device do not have this type of function.
Summary of the invention
At the deficiency that prior art exists, the present invention aims to provide a kind of multifunctional intra-articular fracture guide apparatus.
The technical solution used in the present invention is:
A kind of multifunctional intra-articular fracture guide apparatus, comprise main support arm, leading arm and fixed bar, described main support arm and leading arm are all curved, both socket combinations can be flexible and temporary fixed by knob along the circular arc direction, the inside bending of the front end of leading arm forms the fixing head of pointing to the center of circle, fixed bar can be installed on the main support arm and by knob radial expansion and fix, its front end forms another fixing head of pointing to the center of circle, and the belled position of main support arm and leading arm is provided with a plurality of pilot holes that radially connect.
The outer end diameter of described pilot hole becomes big, forms the counter sink that inserts the guiding latch.
Described pilot hole has 1-5.
Be coated with radial screw guiding latch on the described main support arm.
The fixing head of described leading arm and fixed bar has sharp keen tip.
Described tip is V-shaped.
The present invention can temporary fixed sclerite, can be under the situation that does not enlarge otch, the clear and definite temporary fixed Kirschner wire direction and the screw orientation of bone fixation folded block can also screw in fixing screw from screw guiding latch easily, thereby after having avoided repeatedly bad fixing, the defective that screw lowers fracture fixation intensity, disassembly and assembly easily are to satisfy the requirement of different purposes, owing to be metal material, therefore the use of can sterilizing repeatedly has advantages such as simple in structure, easy operating.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Description of reference numerals is as follows:
1. main support arm 2. leading arms
3. fixed bar 4,4 ＇. knob
5,5 ＇. fixing head 6. pilot holes
7. Kirschner wire guiding latch 8. screws guiding latch
As shown in Figure 1, this guider is mainly by main support arm 1, leading arm 2 and fixed bar 3 constitute, main support arm 1 and leading arm 2 are all curved, leading arm 2 inserts in the main support arm 1, and it is temporary fixed by knob 4, both can be flexible along the circular arc direction, the inside bending of the front end of leading arm 2 forms the fixing head 5 of pointing to the center of circle, fixed bar 3 can be installed on the main support arm 1 and by knob 4 ＇ radial expansion and fix, its front end forms another fixing head 5 ＇ that point to the center of circle, fixing head 5,5 ＇ have sharp keen V-arrangement tip, main support arm 1 has five pilot holes 6 that radially connect with the belled position of leading arm 2, the outer end diameter of pilot hole becomes big, forms the counter sink that inserts Kirschner wire guiding latch 7, and main support arm is coated with radial screw guiding latch 8 at the opposite side of fixed bar 3.
This apparatus has the multi-functional that resets, fixes, leads.For example: when sclerite is separated,, can play a part to reset by this apparatus extruding sclerite; After sclerite resets, by the element that contact with sclerite of locking, perhaps pass through the draw point screw-in fracture end of some, all can temporary fixed sclerite; The topmost function of this apparatus is accurate guide function, because the sensing of each pilot hole is clear and definite, the direction that therefore screws in fine steel needle is also just clear and definite, and on this basis, the hollow screw direction that screws in by fine steel needle is also just clear and definite.
With the knee joint fracture of the tibial plateau is that example is introduced using method: at first according to checking the position of clear and definite sclerite and type of impairment before the art; In the art fixing head is placed on the sclerite central point, by push effect, tentatively sclerite is resetted, the head that is tightened then utilizes pilot hole according to situation in the art, screws in the several pieces of temporary fixed sclerites of 1mm Kirschner wire; Under the situation of not removing this apparatus, rely on C type arm X-ray machine perspective and utilize direct-view affirmation sclerite position satisfaction in the Arthroscopic Operative, screw in the hollow screw bone fixation folded block of suitable length again by temporary fixed Kirschner wire, remove guider and Kirschner wire, close operative incision.
According to arthroscope direct-view in a series of inspections, C type arm X-ray perspective and the arts such as three dimensional CT before the art, can determine Kirschner wire and screw fixed-direction.Because all pilot holes all point to same fixing head position, therefore, judge in conjunction with situation analysis before the art and in the art, then can determine only pilot hole, and then finish corresponding operation.
The present invention is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the present invention or akin technical scheme is all within its protection domain.
