Abstract
The present invention relates to orthopedic medical device fields, specially the V-type osteotomy knife system of bone surgery.Its main feature is that: changeover portion one end connect the other end with osteotomy cutter hub and connect with osteotomy knife bar；Osteotomy cutter hub is equipped with concave hyperboloid, and osteotome, osteotome is at V-shape shape；Further, one end osteotome to the angle between other end osteotome is Φ, and osteotomy cutter hub to osteotome blade end is cone shape.It is of simple structure and low cost.Precisely determine Osteotomy and osteotomy angle, clinical manipulation is easy, shortens operating time, reduces the generation of bad complication caused by bone-culting operation, fracture surgery is conducive to reach good function of joint.
Description
Technical field: the present invention relates to orthopedic medical device fields, specially the V-type osteotomy knife system of bone surgery.
Background technique: the operation for fracture includes osteotomy and soft tissue dissection appears operation, but there is exposures by the latter
Difference is especially difficult the comminuted fracture of articular surface sufficiently to appear articular surface, and the postoperative set time is longer, easily causes and is adhered
The disadvantages of.
The selection of traditional osteotomy instrument includes: osteotome, electronic goose saw and scroll saw etc..Osteotomy mode multiplicity, Ke Yiwei
Horizontal type, oblique type osteotomy and V-type osteotomy.Row osteotomy mode osteotomy face contact is smaller, although osteotomy end is stablized, fixed contraposition is easy
Cause to rotate.Although oblique type osteotomy osteotomy face contact is larger, osteotomy belongs to unstable osteotomy, cuts fracture end and is easy displacement and bone
The generation not connected.And the more cross-section shape osteotomy of V-type osteotomy increases the contact area of the broken ends of fractured bone, osteotomy category stable fracture guarantees to cut
Bone face can be in close contact, the possibility for also preventing the osteotomy broken ends of fractured bone from rotating.
It is widely applied although traditional osteotomy operates, respectively there is a deficiency: 1. traditional osteotome row V-type osteotomy, to behaviour in art
Author is difficult to reach the smooth reset of accurate Osteotomy and articular surface, and it is longitudinal splitting fracture that osteotomy is improper, extends hand
The art time increases the risk of amount of bleeding and postoperative infection.2. the high energy rate of goose saw answers in art through in goose saw row V-type osteotomy
With may make the osteotomy time to shorten, but since swings of high-energy easily leads to bone loss and the surrounding soft tissue of section fracture end
Damage, non-precision cutting plane and osteotomy angle, and easily make to cut fracture end delayed union, it is unfavorable for fracture surgery early function
It takes exercise.3. scroll saw osteotomy, although being the slow osteotomy of low energy, and a section bone loss is handed in and states smaller, the scroll saw osteotomy of the two
Use process must to dialled extensively at osteotomy from, otherwise will lead to neural blood vessel damage, and osteotomy angle be only horizontal type or tiltedly
Type osteotomy, the V-type osteotomy that can not be done use.Therefore, the use of osteotomy instrument is to the accurate osteotomy of Osteotomy and osteotomy angle,
The application of decision ulnar osteotomies fixture and postoperative rehabilitation programme.Osteotomy point and Osteotomy selection in art can only pass through X
After line or CT diagosis by doctor's experience and it is preoperative estimate, the anchor point and Osteotomy of precision can not be obtained, and in art cut
The improper use of bone object tool, and osteotomy surrounding soft tissue is damaged, nonunion at osteotomy, the incidence of traumatic arthritis
Increase.
Summary of the invention: the purpose of the present invention is to provide it is a kind of it is of simple structure and low cost, operate with it is precisely quick,
In operation: 1, it exposes fracture end articular surface adequately, avoids the reset for blocking influence articular surface because of bone tissue；2,
Fracture under direct-view reduction fixation, surgical procedure become easy；3, the more cross-section shape osteotomy of V-type osteotomy increases the broken ends of fractured bone
Contact area, osteotomy category stable fracture guarantee the possibility that osteotomy surface can be in close contact, and also prevent the osteotomy broken ends of fractured bone from rotating；4,
It reduces operation to dial from soft tissue, the damage of muscle is reduced, to reduce bleeding and postoperative adhesions；5, osteotomy proximal end is cancellous bone
Portion has abundant muscle to adhere to, and in conjunction with tension band fixation, has Dynamic compression effect to osteotomy surface, is more advantageous to osteotomy end and is cured
It closes.The object of the present invention is achieved like this: a kind of V-type osteotomy knife system, it includes to strike handle, and osteotomy knife bar, feature exists
In: changeover portion one end connect the other end with osteotomy cutter hub and connect with osteotomy knife bar；Osteotomy cutter hub is equipped with concave hyperboloid, cuts
Osteotome, osteotome is at V-shape shape；
Further, one end osteotome to the angle between other end osteotome is Φ, osteotomy cutter hub to osteotome
Blade end is cone shape；
Further, the osteotomy cutter hub is a length of (L), a height of (M)；
Further, the length (L) of the osteotome is 12-15mm, and high (M) is 40-45mm；
Further, the osteotome end is provided with blade；
Further, the angle Φ is 45 ° -135 °；
Further, angle Φ is 45 ° or 60 ° or 75 ° or 90 ° or 105 ° or 120 ° or 135 °；
Further, the impact handle, osteotomy knife bar, changeover portion, hyperboloid, osteotome, osteotomy cutter hub are integral.
The technical effects of the invention are that of simple structure and low cost.Precisely determine Osteotomy and osteotomy angle, it is clinical
It is easy to operate, shorten operating time, reduce bone-culting operation caused by bad complication generation, for fracture surgery be conducive to
Up to good function of joint.
