The bone cutting guide template comprises a V-shaped photosensitive resin plate and is characterized in that two side arms for forming the V-shaped photosensitive resin plate are a long arm and a short arm, the middle of the long arm is provided with a long stripped upper groove, a long stripped lower groove is formed in the middle of the short arm, an arc-shaped connecting arm is connected between the long arm and the short arm, three fixing holes are formed in the connecting arm at equal intervals, an included angle between the long arm and the short arm is 45 degrees, an included angle between the every two adjacent fixing holes of the three fixing holes is 10 degrees, and inaccuracy of experiential medicine of the bare-handed technology is avoided; the designed long and short arms are favorable for back side long inclined bone surface cutting, so the contact area of the bone cutting surface is larger, the bone cutting is more stable, the inner fixation can be also favorably realized, and the bone cutting guide template conforms to the biomechanics stability; three kirschner wire fixing holes are formed in the middle of the arc-shaped connecting arm at equal intervals, the bone cutting angle can be flexibly selected according to the size of the first metatarsal bone in the operation, and the application range is wider.

Description

The osteotomy guiding die plate that a kind of Yong turns up in Zhi Liao Hallux

Technical field

This utility model relates to Orthopedic operation assist device material technical field, is specifically related to the osteotomy guiding die plate that a kind of Yong turns up in Zhi Liao Hallux.

Background technology

It is foot common disease that Hallux turns up, conventional modus operandi is to move and be screwed in soft tissue release associating metatarsal osteotomy at present, normally with goose saw, carry out V-type and block, then outwards Hui Fu Hallux valgus angle is corrected in translation, and in existing art, conventional osteotomy angle and plane rely on patient's experience.Can only free-handly with sensation, adjust angle at present, but free-hand osteotomy accuracy is too low, cannot accurately control, because extremely easily causing postoperative complication and iatrogenic injury, osteotomy angle and plane occur, in prior art, as application number, for " 201320210645.9 ", be called the utility model patent of " a kind of using in controlling the auxiliary osteotomy equipment of improvement that Hallux turns up for the treatment of ", can avoid the uncontrollability of hand operation, but this equipment dual-side length is identical and angle can not be adjusted, still can not meet the needs of operation completely.

Utility model content

The osteotomy guiding die plate that this utility model provides a kind of Yong to turn up in Zhi Liao Hallux according to the deficiencies in the prior art, can accurately determine osteotomy direction and angle, simple to operate, and registration is safe and scientific effective.

The technical solution of the utility model: the osteotomy guiding die plate that a kind of Yong turns up in Zhi Liao Hallux, comprise V-arrangement photosensitive resin plate, it is characterized in that: the two side arms that forms described V-arrangement photosensitive resin plate is long-armed and galianconism, in long-armed centre, offer the upper groove of strip, in the centre of galianconism, offer the low groove of strip, between long-armed and galianconism, be connected with arc linking arm, three fixing holes that offer in linking arm equal intervals, angle between described long-armed and galianconism is 45 °, and the angle between adjacent two fixing holes of described three fixing holes is 10 °.

The thickness of described V-arrangement photosensitive resin plate is 0.5 ㎝.

Described long-armed length is 4 ㎝, and the length of described galianconism is 2.5 ㎝.

The cannelure inwall of described upper groove is parallel, and the angle of the place plane of described cannelure inwall and long-armed place plane is 0 °.

The cannelure inwall of described low groove is parallel, and the angle of the place plane of described cannelure inwall and galianconism place plane is 0 °.

Technique effect of the present utility model: because the cannelure inwall of upper low groove does not have angle of inclination with respect to the length arm limit (horizontal plane of reference during osteotomy) of V-arrangement osteotomy guiding die plate, like this when osteotomy, the plane of being cut out is parallel with the length arm limit (horizontal plane of reference while being osteotomy) of V-arrangement osteotomy guiding die plate, can accurately locate osteotomy direction and angle, avoid the inaccuracy of " empiricism " of manual techniques; Meanwhile, the length arm of design, improves traditional equilateral osteotomy, is conducive to the long oblique osteotomy surface of dorsal part, and osteotomy surface contact area is larger like this, and osteotomy is more stable, is also conducive to interior fixing, and meets the stable of biomechanics; In the middle of the linking arm of arc, equidistantly offer three Kirschner wire fixing holes, adjacent two fixing hole intervals 10 degree, can art according to the size of first metatarsal, select flexibly the angle of osteotomy, subject range is wider.

Accompanying drawing explanation

Fig. 1 is this utility model overall structure schematic diagram.

Number in the figure represents respectively: 1-V-arrangement photosensitive resin plate, 2-long-armed, 3-galianconism, 4-upper groove, 5-low groove, 6-linking arm, 7-fixing hole.

The specific embodiment

Below in conjunction with accompanying drawing, this utility model is further illustrated:

As shown in the figure, the osteotomy guiding die plate that a kind of Yong turns up in Zhi Liao Hallux, comprise V-arrangementphotosensitive resin plate 1, it is characterized in that: the two side arms that forms described V-arrangementphotosensitive resin plate 1 is long-armed 2 andgalianconism 3, in long-armed 2 centre, offer theupper groove 4 of strip, in the centre ofgalianconism 3, offer the low groove 5 of strip, long-armed 2 andgalianconism 3 between be connected witharc linking arm 6, threefixing holes 7 that offer in linkingarm 6 equal intervals, described long-armed 2 andgalianconism 3 between angle be 45 °, the angle between adjacent two fixing holes of described threefixing holes 7 is 10 °.

The thickness of described V-arrangementphotosensitive resin plate 1 is 0.5 ㎝.

Described long-armed 2 length are 4 ㎝, and the length of describedgalianconism 3 is 2.5 ㎝.

The cannelure inwall of describedupper groove 4 is parallel, and the place plane of described cannelure inwall and the angle of long-armed 2 place planes are 0 °.

The cannelure inwall of described low groove 5 is parallel, and the angle of the place plane of described cannelure inwall andgalianconism 3 place planes is 0 °.

The cannelure inwall of upper low groove does not have angle of inclination with respect to the length arm limit (horizontal plane of reference during osteotomy) of V-arrangement osteotomy guiding die plate, like this when osteotomy, the plane of being cut out is parallel with the length arm limit (horizontal plane of reference while being osteotomy) of V-arrangement osteotomy guiding die plate, has avoided the inaccuracy of " empiricism " of manual techniques; Meanwhile, the length arm of design, improves traditional equilateral osteotomy, is conducive to the long oblique osteotomy surface of dorsal part, and osteotomy surface contact area is larger like this, and osteotomy is more stable, is also conducive to interior fixing, and meets the stable of biomechanics.Equally spacedly in the middle of the linking arm of arc of design offer three Kirschner wire fixing holes, each interval 10 degree, can art according to the size of first metatarsal, select flexibly the angle of osteotomy, subject range is wider.

The osteotomy guiding die plate that a kind of Yong of the present utility model turns up in Zhi Liao Hallux can instruct bone-culting operation, accurately locate osteotomy direction and angle, and then in operation, directly apply osteotomy template osteotomy, and avoid the uncontrollability of hand operation, simple to operate, quick, accurate, safe and scientific effective.
