Abstract
The present invention 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 invention 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 present invention 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.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of dynamic bone towing bracket, the technical scheme is that
Dynamic bone towing bracket, including main body, the main body are integrally formed, and the main body includes that the confrontation portion at rear portion, middle part are led
Draw the crook of portion and front, the convex arc-shaped setting in the confrontation portion, confrontation subordinate end two bending parts backward
After bending, equal horizontally extending formation flat parts forward, the tractive unit is in back-shaped needle-shaped setting, and the one of the tractive unit
End is docked with flat part, and the other end extends forward to be docked with the rear end of crook, the S-shaped setting of the crook, and front end is freely
End.
The medical Kirschner wire that the main body uses length to be 1.2mm for 25cm, diameter is made.
A kind of application method of dynamic bone towing bracket, which comprises the following steps:
(1) confrontation portion is first buckled in the position of proximal phalanx condyles, then laterally squeezes into first piece at the hole that bending part is formed
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 one end of second piece of steel needle, the
The other end of a piece rubber item ties up in a crook of respective side, and one end of second rubber item ties up to the another of second piece of steel needle
One end, the other end of second rubber item tie up in another crook of respective side, and big by two rubber items adjustment tension
It is small.
The invention has the advantages that when being drawn to phalanges, it is only necessary to penetrate two pieces of parallel steel needle (tractive units one on phalanges
Piece, one piece of confrontation portion), the steel needle in confrontation portion need to be unbiased when facilitating postoperative finger passive flexion and extension by phalanges condyle rotation center
Heart movement.And it is securely held between confrontation portion and phalanges, no relative rotation.Smaller to the damage of phalanges, operation difficulty also reduces.It can
Preoperative production is carried out according to fracture and injury mechanism and the actual conditions of displacement, high-temperature sterilization is carried out, can bring on operating table.
Detailed description of the invention
Fig. 1 is agent structure schematic diagram of the invention.
Specific embodiment
The invention will now be further described with reference to specific embodiments, the advantages and features of the present invention will be with description and
It is apparent.But examples are merely exemplary for these, and it is not intended to limit the scope of the present invention in any way.Those skilled in the art
Member it should be understood that without departing from the spirit and scope of the invention can details to technical solution of the present invention and form into
Row modifications or substitutions, but these modifications and replacement are fallen within the protection scope of the present invention.
Referring to Fig. 1, the present invention relates to a kind of dynamic bone towing bracket, including main body 1, which is integrally formed, the master
Body 1 includes confrontation portion 11, the tractive unit 12 at middle part and the crook 13 of front at rear portion, and the confrontation portion 11 is convex arc-shaped
Setting, after two bending parts 14 of 11 lower end of confrontation portion are bent backwards, equal horizontally extending formation flat parts forward
15, the tractive unit 12 is in back-shaped needle-shaped setting, and one end of the tractive unit 12 is docked with flat part 15, and the other end extends forward
It is docked with the rear end of crook 13, the S-shaped setting of the crook, front end is free end.
The medical Kirschner wire that the main body 1 uses length to be 1.2mm for 25cm, diameter is made.
