Description
Technical field
The utility model belongs to medicine equipment, more particularly, is related to oral and maxillofacial surgery and repaiies what is used in reconstructive surgery
Jaw distraction and planting unit.
Background technology
Oral and maxillofacial surgery repaiies the Jaw distraction used in reconstructive surgery at present and planting unit was applicant in 2001
Jaw built-in type traction planting device (the patent No. designed and developed：01238497.6), the device collection jaw bone tractor and tooth kind
Plant, including planting body, cover screw, fixed blade form longitudinal traction planting body and by lifting screw, branch sleeves
And the pilot sleeve composition that fixed blade is formed.Principle：Top movement bone piece, internal thread of sleeve are fixed by planting extracorporeal thread
Conducted as lifting screw thrust, when lifting screw rotates in an anti-clockwise direction in pilot sleeve, promote top bone piece to move up.
This covering device use discovery of getting off has following deficiency：1st, planting body and epimere bone piece are fixed unstable, need to be by blade
Supplementary retention, second operation takes out after implantation is stable, increases the wound and operation difficulty of operation；2nd, the device is led in dismounting
Soft tissue is had after to sleeve to grow into from planting body bottom, causes peri-implantitiss or even retrograde infection occurs；3rd, the dress
Put after completing to draw dismounting sleeve, top traction bone piece usually occur and retract original place, cause traction to fail；4th, the device only with
Upper bone section is fixed, and with lower bone section without maintenance is stablized, adds the unstability of planting body.
Applicant devised in 2012 a set of new Dental implantion tractor (DID) (Chenping, Z., et al.,
Dental implant distractor combined with free fibular flap:a new design for
simultaneous functional mandibular reconstruction.J Oral Maxillofac Surg,
2012.70(11):P.2687-700.), by the interpretation of result to zoopery and clinical trial, Dental implantion traction is developed
Device, the device reduce operation in addition to the characteristic for remaining jaw built-in type traction planting device, by eliminating fixed blade
Operation difficulty and wound, increase dental implants stability by installing base screw additional.Primary structure includes planting body, cover screw,
Base screw and retaining screw form longitudinal traction planting body and the draw-gear group being made up of traction sleeve, screw mandrel and traction cap
Into.
Device after improvement still has following deficiency：Although the 1, enhancing dental implants stability by installing base screw additional,
Be pull out traction sleeve exchanging base screw process it is relatively complicated, doctor usually can not determine base screw after sleeve is removed
On-station position；2nd, after pulling out traction sleeve, it sometimes appear that upper bone section retracts traction front position, so as to influence traction effect；3、
Base screw and retaining screw can increase the stability of planting body and lower bone section, but peri-implantitiss need occur in implant denture
During removal, second operation is generally required by planting body top and the bottom structure while is removed, greatly adds operation wound.
The content of the invention
First purpose of the present utility model, which is to provide after the completion of one kind is drawn, is automatically performed planting body lower end closed, nothing
Need the Dental implantion tractor of mounting seat body again.
To realize object above, the utility model discloses following technical scheme：Dental implantion tractor, including planting body chunk
With traction chunk, it is characterised in that the planting body chunk includes planting body, closing screw and base body, the closing screw
It is connected with planting body threaded upper ends, for closing planting body upper end cavity, the base body is flexibly connected with planting body lower end, institute
State base body lower end and be provided with internal thread, the traction chunk includes connecting screw, and traction screw, inner sleeve and outer sleeve are described
Connecting screw is threadedly coupled with base body, and the traction screw is located at below connecting screw, and the inner sleeve is arranged on base body
Lower section, inner sleeve guide traction screw to promote connecting screw traction in place in distraction procedure, and the outer sleeve is arranged on inner sleeve
Cylinder outer ring, for connecting inner sleeve and base body.
As a preferred scheme, the connecting screw includes connection end and blind end, and the connection end diameter is less than envelope
Closed end diameter, and connection end be able to insert planting body lower end cavity, the blind end is provided with external screw thread.
As a preferred scheme, the length of the connecting screw blind end and the length one of base body lower end internal thread
Cause.Connecting screw is connected with planting body lower end, in distraction procedure promote planting body vertically upward, after the completion of traction with lower bone section
It is fixed.The length of connecting screw blind end is consistent with the length of base body lower end internal thread, prompts due to no screw thread rotation not
It is when drawing in place, to reach traction peak, and screw thread is tightened when dynamic.Length connects when unanimously also can guarantee that traction in place
Screw rod be able to be not prominent to be sunken completely into base body yet.
As a preferred scheme, the connecting screw bottom sets groove, and the traction screw sets raised.Connect spiral shell
The groove of bar and the projection of traction screw block cooperation, and traction screw promotes connecting screw to complete to lead upwards in distraction procedure
Draw, draw traction screw when in place and disengaged automatically with the connecting screw of top.
As a preferred scheme, planting body upper end and base body are respectively provided with the external screw thread with synosteosis.With synosteosis
External screw thread is different from regular screw threads, and helicla flute is shallow, and pitch is big, stable beneficial to bone.
The utility model has the advantage of：(1) base body installation and connecting screw closing, nothing are automatically performed after the completion of drawing
Mounting seat body closing again is needed, so as to simplify operating procedure, reduces clinical manipulation difficulty, while avoids bone section cunning
The problem of falling original position；(2) planting body is that on-fixed is connected with base body connected mode, once there are peri-implantitiss, can be single
Solely planting body is taken out, avoids wound and financial burden that second operation is brought to patient；(3) design of outer sleeve both facilitated
Operation technique, also cleverly connects inner sleeve with base body, when draw complete when, screw off outer sleeve, inner sleeve and base
Body comes off naturally.
