Abstract
The utility model relates to a double-claw sternum fixer for re-fixing sternum. The double-claw sternum fixer is characterized by comprising three parts, namely an upper sliding plate, a fixed baseplate and a positioner, wherein a serrated screw die, a slideway and double claws with inwards bent end parts are arranged on the upper sliding plate, and the upper sliding plate is in sliding fit with the slideway on the fixed baseplate through the slideway on the upper sliding plate; and a baffle plate, a raised column, a small round hole and the double claws with the inwards bent end parts are arranged on the fixed baseplate. The serrated screw die, a spring leaf, a cylindrical hole and an irregular hole matched with a rotating screw are arranged on the positioner, and the rotating screw is fixed with a bottom ring fixed on the bottom surface of the baseplate. Compared with the prior art, a method for fixing the sternum by bundling with steel wires or titanium alloy wires in a traditional operation is changed, and the double-claw sternum fixer can not only shorten operation time and be easy to operate, but also avoid the occurrence of arterial injuries in breasts, postoperative mediastinal infection, sternum dehiscence and other complications, and reduce the trauma and the suffering of patients; and simultaneously, the fixer is easy to lock and unlock and can be used repeatedly.
Description
Technical field
This utility model belongs to surgery and is used for closure of wound or keeps wound closure use the technique with the apparatus field, relates to a kind of surgical operation center and indulges the two pawl breastbone holders that are used to retighten breastbone behind the shape sternotomy.
Background technology
At present, most hearts both domestic and external, pericardium and part operation on mediastinum all adopt chest center pathway to carry out, and promptly vertical shape is rived and performed a surgical operation behind the breastbone.Two halves breastbone closed and retighten the mode that generally adopts steel or titanium alloy wire to tie up and fix about when operation finishes.But old people, especially osteoporosis person are found in the clinical practice according to for many years; The operation back is used above-mentioned tinsel fixed form and is easy to cause the breastbone cutting; So that breastbone is trembled out or mediastinal infection, and children's uses above-mentioned tinsel fixed form if steel wire can cause that equally breastbone isolates when twisting tightly because of sclerotin is poor; If the breastbone poor stability had the possibility that causes children's's pigeon chest when steel wire was twisted laxly.In addition, tinsel also can cause a series of problems such as hemorrhage, fracture of medullary cavity and tissue.Sometimes spending in the time that postoperative breastbone hemostatic time ratio undergos surgery also will grow; If tinsel kink undue force during operation; Then be easy to rupture, must settle again, not only cause bigger wound, misery and risk to patient; And the time and the working strength of increase doctor operation, waste of manpower, material resources and limited blood source or the like.These problems all are that the clinicist can't fine solution and very worried problem always for a long time.
Summary of the invention
To above-mentioned prior art situation, the purpose that this utility model solves is, provides a kind of surgical operation to drive behind the breast implanted pair pawl breastbone holders that be the basis, that be used to retighten breastbone with the Chinese human physilogical characteristic.
This utility model design and concrete technical solution are narrated as follows at present:
This utility model surgical operation is characterized in that: constitute (see figure 1) by upper slide 1, fixed base plate 2 and localizer 3 three parts with two pawl breastbone holders; Upper slide 1 is slidingly matched and (sees Fig. 3 through
shape slideway 7 on
shape slideway on it 5 and the fixed base plate 2; 4; 5); The base ring 16 of fixed base plate 2 bottom surfaces is with localizer 3 and fixing negative 2 (see figure 5) that is fixed together.
This utility model further provides a kind of surgical operation with two pawl breastbone holders, it is characterized in that: upper slide 1 is provided with zigzag screw die 4 and
shape slideway 5 (see figure 6)s and end two pawls 6 (see figure 7)s of
curved shape inwardly.
This utility model further provides a kind of surgical operation with two pawl breastbone holders, it is characterized in that: fixed base plate 2 be provided with upper slide 1 on
shape slideway 5
the shape slideway 7 (seeing Fig. 8,10), plate washer 8, protruding column 9 and the small sircle hole 10 that cooperate and end two pawls 11 (seeing Fig. 9, Figure 11) of
curved shape inwardly; Plate washer 8 is positioned between
shape slideway 7 of spring leaf 15 and fixed base plate 2 of localizer 3.
This utility model further provides a kind of surgical operation with two pawl breastbone holders, it is characterized in that: have zigzag screw die 14, spring leaf 15, cylindrical hole 13 on the localizer 3 (seeing Figure 12) and cooperate the irregular hole 17 (seeing Figure 17) of assembling with rotary screw 12; Rotary screw 12 cooperated be installed in the small sircle hole 10 on the fixed base plate 2 the end face riveted joint of thin cylinder 18 or weld together on the base ring 16 of fixed base plate 2 bottom surfaces and the rotary screw 12 through irregular hole 17 correspondences.Simultaneously cylindrical hole 13 is enclosed within on the protruding column 9 on the fixed base plate 2 on the localizer 3, with localizer 3 and fixed base plate 2 link together (seeing Figure 13, Figure 14, Figure 15, Figure 16, Figure 17, Figure 18, Figure 19).
This utility model further provides a kind of surgical operation with two pawl breastbone holders; It is characterized in that: the bottom of described rotary screw 12 is thin cylinder 18; A convexity 19 is arranged at the top of thin cylinder 18, and protruding 19 top is one to be easy to the medicated cap 20 (seeing Figure 18,19) screwed with instrument; Described irregular hole 17 is one can carry out the concavo-convex hole that cooperates with the convexity 19 of rotary screw 12; Rotate rotary screw 12, through protruding 19 motions in irregular hole 17, drive spring leaf 15 opening and closing, the sawtooth of control zigzag screw die 14 and the mutual interlock of sawtooth of the zigzag screw die 4 on the upper slide 1 reach the state of opening, close, locking.
This utility model has compared with prior art changed traditional operation fully and has adopted steel wire or titanium alloy wire to tie up the fixedly pass breast method of breastbone, and only need beaten preparatory hole in the intercostal space on the breastbone both sides of riving, and closes locked getting final product after putting into this holder.Thereby make operating time shorten greatly, perform the operation be easier to the operation; The application of this holder not only can be avoided the generation of complication such as IMA damage and the vertical diaphragm of postoperative infect, breastbone is trembled out; And can reduce patient's wound and misery; Shorten doctor's operating time, the easy lock of this monodactyle breastbone holder is prone to out simultaneously, can be repeatedly used.
