Description
Technical field
The present invention is novel to belong to field of medical device, a kind of orthopaedics dismounting screw means reducing wound.
Background technique
Currently, the common screw dismounting tool of orthopaedics is difficult to operate, encounter it is both time-consuming when tighter screw dismounting is installed,
It is again laborious, even occur the situation for causing bone split, bone broken that overexerts sometimes, it is also possible to which dynamics not enough causes loosened screw etc. to ask
Topic, not only causes great pain to patient, while also causing greatly to perplex to the work of medical worker.
Summary of the invention
The novel purpose of the present invention provides a kind of orthopaedics dismounting screw means for reducing wound, can not only overcome existing
Screw dismounting defect, convenient process dismount to screw more gives reinforcing setting to the screw of more difficult dismounting, logical
Accurate force is crossed, in order to avoid cause unnecessary medical fault.
In order to solve the above-mentioned technical problem, the novel technical solution of the present invention is：A kind of orthopaedics for reducing wound dismounts spiral shell
Adjusting screw device includes cutter head fixed card buckle, and reinforcing swingle one end is connect with cutter head fixed card buckle, the other end and rotating handle connect
It connects, rotating handle front of motor is connect by straight-bar with reinforcing rotating seat；
Universal rotary runner is equipped in the reinforcing rotating seat.
Further, described device further includes the sleeve being set on reinforcing swingle and the branch being connected on the sleeve
Support.
Further, the support frame includes the curved support of the transverse slat being connected on bedstead and the connection transverse slat
Bar, the arc support rod and sleeve connection.
Further, the transverse slat is equipped with multiple threaded holes, and arc support rod is equipped with external screw thread one end and passes through threaded hole
It is connected on transverse slat.
Further, the transverse slat is equipped with a plurality of soft band.
Further, the reinforcing swingle is equipped with upper limit ring, lower limit ring, and sleeve is along reinforcing swingle described
Upper limit ring, slide between lower limit ring.
The present invention has following advantages：1. due to normal aggregates screw solution knife when encountering the screw of more difficult dismounting expense
When, it is laborious, even occur the situation for causing bone split, bone broken that overexerts sometimes, it is also possible to which dynamics not enough causes loosened screw etc.
Problem not only causes great pain to patient, while also causing greatly to perplex to the work of medical worker, reinforces swingle
Several times pressure can be increased to common solution knife, it is time saving and energy saving, it can directly make medical worker when encountering the screw of more difficult dismounting
It completes to operate by pressurizing tool, the convenient process for dismounting screw more sets the reinforcing of giving of the screw of more difficult dismounting
It sets, by accurately exerting a force, in order to avoid cause unnecessary medical fault.
2, the device can be carried out when operation is by a doctor, not need other doctor's cooperations, need to increase rotation
When power, device can be limited by the shoulder of doctor, with the hands rotating device so as to screw is fixed or
It is to remove.
Detailed description of the invention
It is novel to the present invention with reference to the accompanying drawings and examples to be described further.
Fig. 1 is the novel structural schematic diagram of the present invention.
Fig. 2 is preferred structure schematic diagram of the present invention.
Fig. 3 is support frame preferred structure schematic diagram.
Fig. 4, which is that the present invention is another, selects structural schematic diagram.
In such as figure, cutter head fixed card buckle 1, reinforcing swingle 2, rotating handle 3, reinforcing rotating seat 4, support frame 5, sleeve 6,
Upper limit ring 21, lower limit ring 22, transverse slat 51, arc support rod 52, threaded hole 53, soft band 54.
Specific embodiment
As shown in Figure 1, a kind of orthopaedics dismounting screw means for reducing wound include cutter head fixed card buckle 1, reinforcing rotation
Length 30cm, the diameter 1cm of bar, reinforcing 2 one end of swingle is connect with cutter head fixed card buckle 1, the other end and rotating handle 3 connect
It connects, 3 front of motor of rotating handle is connect by straight-bar with reinforcing rotating seat 4, in use, 1 connecting screw of cutter head fixed card buckle, doctor
A raw holding reinforces rotating seat, and another holds rotating handle 3, and makes, and screw can be screwed in or screw is screwed out steel
Plate.
Preferably, as in Fig. 4, Universal rotary runner 7 is equipped in the reinforcing rotating seat 4, when screw needs are larger
When power is taken out, the Universal rotary runner 7 of rotating seat 4 can be made to abut against the shoulder of doctor, and made on cutter head fixed card buckle 1 and steel plate
Screw be in contact, to take out the screw on steel plate, both hands can apply both hands rotation rotating handle 3 than one hand later
Power is too big, because of the applied force by the way of holding, compares mechanical system applied force, easier to control, so that the screw avoided exists
When taking-up because power apply it is uneven or excessive caused by damage.
In Fig. 2, it is a kind of reduce wound orthopaedics dismounting screw means further include be set in reinforcing swingle 2 on set
Cylinder 6 and the support frame 5 being connected on the sleeve 6.
Preferably, as shown in figure 3, support frame 5 includes the arc of the transverse slat 51 being connected on bedstead and the connection transverse slat 51
Shape support rod 52, the arc support rod 52 are connect with sleeve 6, it is further preferred that transverse slat 51 is equipped with multiple threaded holes
53（Multiple threaded holes 53 are set and are conducive to the different location that arc support rod 52 is placed on to transverse slat 51, realize different location hand
Art）, arc support rod 52 be equipped with external screw thread one end be connected on transverse slat 51 by threaded hole；
Preferably, transverse slat 51 is equipped with a plurality of soft band 54, and operative site can be fixed on transverse slat 51 by soft band 54.
In use, first transverse slat 51 is fixed on bedstead, and the part performed the operation will be needed to be fixed on transverse slat by soft band 54
On 51, the position by adjusting arc support rod 52 on transverse slat 51 later so that the contraposition of cutter head fixed card buckle 1 need to fasten or
It is the screw taken out, sleeve 6 slides inversion along reinforcing swingle 2（I.e. transverse slat 51 passes through arc support rod 52,6 pairs of sleeve reinforcings
Swingle 2 forms support, and the screw before reinforcing swingle 2 and cutter head fixed card buckle 1 and the center line of reinforcing rotating seat 4 is made to exist
On straight line）, reuse hand-tight holds and reinforce rotating seat 4 or resist reinforcing rotating seat 4 with shoulder, later again with another
Hand rotation rotating handle 3 or both hands rotate rotating handle 3.
Preferably, the reinforcing swingle 2 is equipped with upper limit ring, lower limit ring, and sleeve 6 is along reinforcing swingle 2 in institute
It is slided between the upper limit ring 21 stated, lower limit ring 22, upper limit ring 21, lower limit ring 22 can be to the cunnings of sleeve 6 in setting
Dynamic position is defined, and to prevent sleeve 6 to be stuck in cutter head fixed card buckle 1 or rotating handle 3, influences the use of the present apparatus.
