Description
Technical field
The utility model is related to medical instruments field, more particularly to a kind of micro screw fastening handle.
Background technology
Micro screw is common a kind of planting body in orthodontic field.As a kind of temporary device, in patient mouthful
The specific position of intracavitary is implanted into micro screw with operation method, and specific anchorage can be provided for orthodontic treatment, and auxiliary is completed just
Abnormal treatment.
In 1997, Kanomi proposed the micro screw dedicated for orthodontic treatment.Second year, Costa etc., which is devised, to be had
The drive screw of bracket sample micro screw simultaneously starts clinically to apply.Hereafter, the micro screw of various different designs and details starts greatly
Amount occurs, and has pushed the development of clinical application.
People usually utilize micro screw fastening handle, and micro screw is rotated and is fixed on the gum of patient.Fixing it
Before, it is necessary first to micro screw is mounted on to the head of micro screw fastening handle.
In the Chinese utility model patent application No. is CN200320124802.0, a kind of typical micro screw is disclosed
Structure is provided with through-hole on the head of this kind of micro screw.This through-hole is in addition to can be used for other than with fixed arch wire, also
It can be used as the slot on micro screw fastening handle.
Shown in Fig. 1, Fig. 2 and Fig. 3, existing micro screw fastening handle includes handle body 7, neck 1 and head 2, neck 1
Be connected on handle body 7, head 2 is connected on neck 1, is formed with the groove for being put into micro screw on head 2, groove it is interior
Bolt 3 is provided on wall, bolt 3 is fixed by elastic component, has certain stroke.When through-hole as slot in use, micro- spiral shell
Nail is filled in groove, depends on stroke caused by elastic component by bolt 3 into insertion slot.
But in order to ensure that micro screw can successfully fill in groove, the stroke of bolt 3 can not be arranged very long.And
It during micro screw rotates, while being acted on by the strength of gum and micro screw fastening handle, the stroke of bolt 3 will be too short to be difficult to
Enough fixed effects are provided.Therefore existing micro screw fastening handle is easy to skid during fastening micro screw, causes
Micro screw is fallen.
Again since in order to ensure gnotobasis, micro screw is usually disposable product and expensive, therefore, micro-
Screw to fall the loss brought very huge.
Utility model content
The purpose of this utility model is to provide a kind of micro screw fastening handle, which can prevent micro-
Screw is fallen.
In order to solve the above-mentioned technical problem, the utility model provides a kind of micro screw fastening handle, for fastening micro- spiral shell
Nail, including:
Neck, button is provided on neck, and button includes keycap and is used to support the spring of keycap;
Head, head are formed with the groove for being put into micro screw;It is provided with bolt on the inner wall of groove;
Transmission component is set to the inside of neck, for connecting keycap and bolt;
When pressing keycap, spring-compressed, keycap drives bolt along the radial motion on head by transmission component;
When decontroling keycap, spring restores deformation, and keycap drives diameter of the bolt along head to yearn on the contrary by transmission component
Direction moves.
In terms of existing technologies, the utility model controls the movement of bolt by using button so that bolt
Stroke is unrelated with the action that micro screw fills in groove, and can it is accurate according to the structure design of transmission component and quantitatively control insert
The stroke of pin improves the fixed effect of micro screw, it is therefore prevented that micro- spiral shell so that bolt can be inserted into deeper into ground in slot
Nail is fallen.
Preferably, transmission component includes:
The both ends of drive link, drive link are separately connected button and the bolt with button homonymy;
When pressing keycap, spring-compressed, keycap drives bolt along the radial motion on head by drive link, makes bolt and sets
The slot being placed on micro screw mutually plugs together;
When decontroling keycap, spring restores deformation, and keycap drives bolt along the radial motion on head, makes to insert by transmission component
The slot sold and be set on micro screw is separated from each other.
It drives bolt to move using drive link, there is advantage simple in structure, highly reliable.
Alternatively, preferably, transmission component includes:
The both ends of drive link, drive link are separately connected button and the bolt with button opposite side;
When pressing keycap, spring-compressed, keycap drives bolt along the radial motion on head by drive link, makes bolt and sets
The slot being placed on micro screw is separated from each other;
When decontroling keycap, spring restores deformation, and keycap drives bolt along the radial motion on head, makes to insert by transmission component
The slot sold and be set on micro screw mutually plugs together.
When drive link connection be the bolt of opposite side when, pressing keycap can bolt and to be set on micro screw
Slot is separated from each other, and bolt is located at the state mutually plugged together with the slot being set on micro screw in the case that this makes acquiescence,
So that doctor is not necessarily to constantly press & hold during using micro screw fastening handle, it is more laborsaving.
Preferably, button, drive link and bolt are all respectively two, and button and bolt pass through transmission group correspondingly
Part is connected;
Wherein, two buttons are located at both sides opposite on neck, and two bolts are also located at this both sides.Work as both sides
Be both provided with bolt and all by by key control when, can so that the bolt of both sides all has enough strokes, improve fixed effect.
In addition, preferably, there are two bolts, two bolts are located at both sides opposite on neck, respectively left side
Bolt and right side bolt are arranged on bolt with teeth;
Transmission component includes:
Actuator;
Central gear is sequentially connected with keycap by actuator;
