Abstract
The utility model relates to dynamic bone towing brackets, including main body, the main body is integrally formed, the main body includes confrontation portion, the tractive unit at middle part and the crook of front at rear portion, the convex arc-shaped setting in the confrontation portion, after two bending parts at confrontation subordinate end are bent backwards, horizontally extending formation flat part forward, the tractive unit is in back-shaped needle-shaped setting, it is docked with flat part one end of the tractive unit, the other end extends forward to be docked with the rear end of crook, and the S-shaped setting of the crook, front end is free end.The utility model has the advantages that: when being drawn to phalanges, it is only necessary to penetrate two pieces of parallel steel needles (one piece of tractive unit, one piece of confrontation portion) on phalanges, the steel needle in confrontation portion need to be moved without acceptance of persons when facilitating postoperative finger passive flexion and extension by phalanges condyle rotation center.And it is securely held between confrontation portion and phalanges, no relative rotation.Smaller to the damage of phalanges, operation difficulty also reduces.
Description
Technical field
The utility model relates to dynamic bone towing brackets, belong to medical instruments field.
Background technique
The treatment of interphalangeal joint intra-articular fracture is one of hand surgical clinical problem, and sclerite is often comminuted, and is involved
Articular surface merges abarticulation and rock-steady structure damage.Finger joint style in-seam splits type: I type is the stable fracture without displacement；
II type is single condylar fracture, unstable fracture；Other fracture, back side palmar or sides of III type phalanges condyles fracture, head of phalanx
Substrate fracture.
Comminuted intra-articular fracture, the especially fracture of middle phalanx substrate, referred to as pilon fracture, which is mostly axis
To caused by load, show as articular surface center collapse and fracture line to joint margins extend.
Two class methods of nearly interphalangeal joint intra-articular fracture treatment: first is that emphasize that should pursue anatomical reduction is principle of reatment,
Advocate row open reduction and Kirschner wire fixation (traditional AO fractures principle 1958)；It is another kind of to strive for that joint early functional exercise is
Target is maintained to draw, be answered using " capsule ligament reduction " principle intra-articular fracture using outer fixation to damaged joints
Position.
Interphalangeal joint intra-articular fracture, using traditional internal fixation, though it is able to maintain the steady of joint and fracture
It is fixed to reset, but early stage joint motion can not be carried out, it is braked since the long-time of gypsum and steel needle is fixed, joint capsule and collateral ligaments
Contracture, anchylosis.In terms of the biomethanics of finger function, nearly interphalangeal joint bends and stretches functional importance and is only second to metacarpophalangeal pass
Section needs early ambulant joint for the degree for reducing anchylosis and contracture.And the healing fractured needs to be fixedly secured joint,
So there are contradictions for the two.To solve this problem, we make great efforts to seek a kind of reset that can effectively maintain fracture and joint,
Joint can allow for carry out the device of early exercise again.
The power Bone traction technology described on " Green's hand odonto-maxillary sursery " is needed when carrying out draw operations in phalanges
On penetrate more steel needles, larger to injury of human, operation difficulty is high, and closely saves the confrontation steel needle of distal phalanx condyles, no
It can be rotated with finger flex, if competency bends and stretches finger, cause the drawbacks of steel needle is to phalanges cutting, friction, in turn
Cause the complication such as pin site infection exudation；Hitch frame simultaneously needs operative site to make, more demanding to patient's operational capacity.
Utility model content
To overcome the shortcomings of existing technologies, the utility model provides a kind of dynamic bone towing bracket, the skill of the utility model
Art scheme is:
Dynamic bone towing bracket, including main body, the main body are integrally formed, and the main body includes confrontation portion, the middle part at rear portion
Tractive unit and front crook, the convex arc-shaped setting in the confrontation portion, two bending parts at confrontation subordinate end
After bending backwards, horizontally extending formation flat part, the tractive unit are in back-shaped needle-shaped setting, the tractive unit forward
One end docked with flat part, the other end extends forward to be docked with the rear end of crook, and the S-shaped setting of the crook, front end is
Free end.
The medical Kirschner wire that the main body uses length to be 1.2mm for 25cm, diameter is made.
The application method of dynamic bone towing bracket:
(1) confrontation portion is first buckled in the position of proximal phalanx condyles, the is then laterally squeezed at the hole that bending part is formed
One piece of steel needle；
(2) second piece of steel needle parallel with first piece is then squeezed into the middle part of the sliding eye of tractive unit；
(3) two rubber items of sterile rubber gloves clip are taken, one end of first rubber item ties up to the one of second piece of steel needle
End, the other end of first rubber item tie up in a crook of respective side, and one end of second rubber item ties up to second piece of steel
The other end of needle, the other end of second rubber item tie up in another crook of respective side, and pass through two rubber item adjustment
Tensity size.
The utility model has the advantages that: when being drawn to phalanges, it is only necessary to penetrate (the traction of two pieces of parallel steel needles on phalanges
One piece of portion, one piece of confrontation portion), the steel needle in confrontation portion need to by phalanges condyle rotation center, when facilitating postoperative finger passive flexion and extension,
It moves without acceptance of persons.And it is securely held between confrontation portion and phalanges, no relative rotation.Smaller to the damage of phalanges, operation difficulty also drops
It is low.Preoperative production can be carried out according to fracture and injury mechanism and the actual conditions of displacement, carry out high-temperature sterilization, operating table can be brought into
On.
Detailed description of the invention
Fig. 1 is the agent structure schematic diagram of the utility model.
Specific embodiment
Further describe the utility model combined with specific embodiments below, the advantages of the utility model and feature will be with
Description and it is apparent.But examples are merely exemplary for these, does not constitute any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under the spirit and scope without departing from the utility model
The details and form of art scheme are modified or are replaced, but these modifications and replacement each fall within the protection scope of the utility model
It is interior.
