Description
Technical field
The utility model relates to a kind of medicine equipment, (is called for short pin hole bone to squeeze particularly to a kind of pin hole Bone condensing reamer
Expand device).
Background technology
After causing patient's defect of dentition or disappearance due to many reasons, the thickness of patient's alveolar ridge or alveolar process, i.e. words/
There is such and such change to thickness or cheek tongue/jaw to thickness meeting more or less in jaw, with the growth of mistake tooth time, tooth
The trend of the bone lower thickness on groove ridge top is more obvious, and female patient becomes apparent from compared with the male sex, and assembling activity artificial tooth is less
Wearer is obvious, thus gives the problem that tooth-implanting curative activity brings a Bone mineral change.Special from aesthetic orthopaedics (few patients)
Other require consider, the case that words/jaw be short of to thickness, doctor can advise patient do bone increment perform the operation, i.e. Psoralen or
Bone grafting, or use the methods such as Split-crest to recover thinning part, then do implant prostheses again；Examine from ordinary circumstance
Consider, i.e. most of patients, especially ability to pay are limited, be unwilling to spend the too many time, less demanding to aesthetic effect,
And fear plantation only accepts Minimally Invasive Surgery, " solving disappearance first, aesthetic requirement is secondly " becomes the demand of more patient.
Utility model content
When running into slim alveolar ridge/prominent, it is impossible to use bone increment, this generates the measure needing " suiting measures to local conditions ",
I.e. " the squeezed technology of pin hole " and the matched utensil of the preparation restricted bed of tooth implant of the utility model people design, with the most micro-
Little wound or the storing operation realizing planting body without complication.
The utility model of the squeezed device of the utility model pin hole bone and technology application thereof compares with tradition planting technology or method,
Emphasis solves knotty problem: 1) bladed alveolar ridge (ridge top thickness degree 3.0mm)；2) forward and backward anodontia tooth district small-gap suture
(near and far distance 3.5mm between two coronas, crest of alveolar ridge thickness 4.0mm)；3) implant operation of upper jaw backteeth jaw side seam；4)
And the Implant of other residue alveolar process or ridge parietal bone.If several situations use existing single traditional planting technology above
Or method all do not accomplishes.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
The squeezed device of pin hole bone disclosed in the utility model, including the stabilizers sequentially coaxially connecting, screw portion, tapping screw thread
Portion, the second threaded portion, lead, pointed nose, described stabilizers is cylinder, and the described portion of screwing is noncircular cross section cylinder, institute
Stating the small end in tapping screw thread portion and the second threaded portion connecting, described second threaded portion is cylinder, and the second threaded portion is provided with outer spiral shell
Line, described lead is cylinder, and described pointed nose is prismatic.
Using method of the present utility model:
After the tooth-implanting recipient bed alveolar ridge determining/prominent top uses pin hole boring, by the prismatic of squeezed for pin hole device
Pointed nose inserts positioning spicule hole, and after penetrating bone plane pin hole, turn clockwise squeezed device, and the Rhizoma Sparganii part at its tip has to squeeze cuts
The effect of bone (especially I, II class cortex bone), the beneficially insertion of rear portion lead；Cylinder lead is pin hole bone
Squeezed device plays the part of direction guiding function, and the direction can bored along pin hole due to smooth cylinder is moved, without departing from；Second
Threaded portion is the transition between lead and the second threaded portion, has the existence of fine thread (screw thread of the second threaded portion), rotation
When turning squeezed device, fine thread closely embeds cortex of bone and is gradually introduced rear portion coarse-pitch thread (screw thread of the second threaded portion), implements to bone
The extruding reaming effect of tissue.Pin hole brill is the first step of reaming, and the squeezed device of pin hole is the second step of reaming, and the 3rd is to use
The big squeezed device of more large size uses reaming step by step in order, until the planting body being suitable for is put into.
Preferably, the described radial dimension more than stabilizers for the radial dimension screwing portion.
Preferably, the described portion of screwing is six prisms.
Further, the cone angle in described tapping screw thread portion is 6 °, and the pitch of thread is 1.25mm, and thread groove cross section is circular arc,
The radius of described circular arc is 1.5mm.
Further, a diameter of 1.2mm of described tapping screw thread portion taper end.
Preferably, the described second a diameter of 1.2mm in threaded portion, pitch is 0.3-0.6mm, and spiral shell trench depth is 0.15-
0.25mm, a length of 2-4mm, thread groove cross section is triangle.
Preferably, a diameter of 1.0mm of described lead, a length of 2-3mm.
Further, described pointed nose and lead end face are adapted to, a length of 1mm to 1.5mm of pointed nose.
Further, also including connecting portion, described connecting portion one end is connected with tapping screw thread portion, the connecting portion other end and rotation
The portion of twisting connects.
Preferably, described connecting portion is cylinder, and connecting portion is coaxial with tapping screw thread portion.
The utility model has the advantages that
1. the utility model structure, exquisiteness, operation is expanded in the extruding being highly suitable for pin hole bone；
2. stablizing when stabilizers can keep squeezed device to rotate, it is ensured that squeezed angle and direction；
3. screw portion and implement apparatus adaptation, the convenient enforcement rotating；
4. the length difference of connecting portion goes for the squeezed operation of different depth, convenient enforcement.
5. prismatoidal pointed nose, is the function top of the squeezed device of pin hole, acts on one: find the spicule of plane during positioning
Hole；Effect two: rotating squeezed device after penetrating bone plane pin hole, its prismatoidal pointed nose has crowded deep (especially I, II class skin
Matter bone) effect, the beneficially insertion in rear tapping screw thread portion；
6. lead is the part that the squeezed device of pin hole bone plays direction guiding function, owing to smooth cylinder can bore along pin hole
Direction move, without departing from；
7. fine thread (screw thread of the i.e. second threaded portion) is the transition between lead and tapping screw thread portion, has thin spiral shell
The existence of line, when rotating squeezed device, fine thread closely embeds the first screw thread that cortex of bone is gradually introduced rear portion；
8. tapping screw thread portion has certain cone angle, can effectively carry out to bone tissue extruding reaming.
