The utility model provides a kind of screwdriver for being used to take out the screw that fractures in tooth implant, solves the screw hardly possible that fractures
The problem of to take out.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：One kind is used to take out tooth implant infolding
The screwdriver of disconnected screw, it is characterised in that：Including cutter hub, supporting plate, soft rubber sleeve, cutter hub by integral structure handle and
Bar portion forms, and can be relatively rotated after the upper end of handle and the middle part connection of supporting plate, soft rubber sleeve is arranged on the work of bar portion
Make on end；The end face of soft rubber sleeve is set to be bonded with the section for the screw that fractures in use, pushing supporting plate, while rotate counterclockwise
Cutter hub, the screw that fractures take out the screw that fractures with soft rubber sleeve synchronous rotary.
To the further restriction of above-mentioned technical proposal, the attachment structure of the cutter hub and supporting plate is：In the upper end of handle
Bearing pin is upwardly extended at the heart, supporting plate is arranged on bearing pin by nut, and gap, supporting plate are left between supporting plate and handle
Deep gouge is provided with, nut is located in deep gouge.Advantage：Demountable, it is easy to cleaning-sterilizing, avoids pathogen transmission.
To the further improvement of above-mentioned technical proposal, the supporting plate is provided with finger ring, and finger ring is elastic rubber ring.It is excellent
Point：Finger ring is avoided that the problem of apparatus easily comes off with human hands in use, and simple in construction, production cost
It is low.
To the further restriction of above-mentioned technical proposal, the bar portion is made up of permanent-magnet material.Advantage：Bar portion has magnetic property
The screw for preventing from taking out drops in patient oral cavity.
To the further restriction of above-mentioned technical proposal, the working end of the bar portion is provided with multiple limit convexes being spaced apart
Rise, the working end of soft rubber sleeve and bar portion is connected as one by vulcanization.Advantage：Integral structure simplifies production work
Skill, production cost is reduced, the problem of integrally being scrapped after damaging be present.
To the further restriction of above-mentioned technical proposal：The working end of the bar portion is provided with anti-pitch thread, soft rubber sleeve
Cavity wall be provided with internal thread, the working end of bar portion is threadedly coupled with soft rubber sleeve.Advantage：The soft rubber of Demountable
Sleeve, flimsy soft rubber sleeve is conveniently replaceable, avoids overall the problem of scrapping, reduce the wasting of resources.
Beneficial effect：1. cutter hub is made up of handle and bar portion, handle is easy to fingerhold, and bar portion is easily inserted into tooth implant
It is interior；2. cutter hub combines with supporting plate, the stability of fingerhold apparatus is improved, and does not interfere cutter hub to rotate；3. soft rubber exists
There is higher stickiness with the screw broken ends of fractured bone under certain pressure, using the teaching of the invention it is possible to provide enough frictional force, ensure that the screw that fractures with soft rubber
Sleeve rotates counterclockwise, so as to take out the screw that fractures；4. the utility model is simple in construction, easy to operate, low manufacture cost, and solves
Determined fracture screw be difficult to take out the problem of.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 use state figure.
Fig. 3 is another attachment structure schematic diagram of cutter hub and supporting plate.
Embodiment
It is a kind of to be used to taking out the screwdriver of the screw that fractureed in tooth implant as shown in Fig. 1, including cutter hub 1, supporting plate 2,
Soft rubber sleeve 3, cutter hub 2 are made up of the handle 101 and bar portion 102 of integral structure, i.e. handle 101 and the axis of bar portion 102
Overlap；The upper end of handle 101 can relatively rotate after being connected with the middle part of supporting plate 2, i.e., upward at the upper end center of handle 101
Be extended with bearing pin 1011, supporting plate 2 is arranged on bearing pin by nut 1012, leaves gap between supporting plate 2 and handle 101,
Supporting plate is provided with deep gouge, and nut is located in deep gouge；Supporting plate 2 is provided with the finger ring 201 of bonding, and finger ring 201 is elastic caoutchouc
Ring；Soft rubber sleeve 3 is arranged on the working end of bar portion 102, i.e., the working end of bar portion 102 is provided with anti-pitch thread 1021, soft
The cavity wall of rubber bush 3 is provided with internal thread, the working end of bar portion 102 is threadedly coupled with soft rubber sleeve 3.
Known screw clockwise turn to tighten, rotate counterclockwise is unscrews；Because bar portion is provided with anti-pitch thread, when soft rubber
It is tight condition during rubber sleeve rotate counterclockwise, clockwise turns to and unscrew state；Therefore, when unscrewing screw, soft rubber sleeve
For tight condition, so as to avoid the problem of soft rubber sleeve and cutter hub relatively rotate.In use, operator's thumb and
Handle in middle finger clamping cutter hub, supporting plate are resisted against on forefinger, soft rubber sleeve are inserted into tooth implant 4；Such as Fig. 2 institutes
Show, pushing supporting plate makes the end face of soft rubber sleeve be bonded with the section for the screw 5 that fractures, while rotate counterclockwise cutter hub, fractures
Screw rotates with cutter hub, that is, takes out the screw that fractures.
As shown in Fig. 2 the section of screw is in rough and uneven in surface, the convex portion on its section is embedded in soft rubber under pressure
It is interior, realize that soft rubber sleeve can be bonded with screw section, fitting ensure that there is enough frictional force between the two, so as to realize
Screw fracture with soft rubber sleeve synchronous rotary.
As shown in figure 3, another attachment structure of the cutter hub and supporting plate is：Set on the working end of the bar portion 102
There are multiple spacing preiections 1022 being spaced apart, the working end of soft rubber sleeve and bar portion is connected as one by vulcanization.
During use：Handle in thumb and middle finger clamping cutter hub, supporting plate are resisted against on forefinger；Pushing supporting plate makes soft rubber sleeve
