Description

The squeezed device of pin hole bone

Technical field

The present invention relates to a kind of medical apparatus and instruments, (be called for short pin hole particularly to a kind of pin hole Bone condensing reamer The squeezed device of bone).

Background technology

After causing patient's defect of dentition or disappearance due to many reasons, patient's alveolar ridge or the thickness of alveolar process Such and such change is there is to thickness meeting more or less in degree, i.e. words/jaw to thickness or cheek tongue/jaw Changing, with the growth of mistake tooth time, the trend of the bone lower thickness of alveolar ridge crest is the most obvious, female patient Relatively male becomes apparent from, and the less wearer of assembling activity artificial tooth is obvious, thus gives Dental Implant medical treatment work The problem bringing a Bone mineral change.Particularly require from aesthetic orthopaedics (few patients) to consider, right In the case that words/jaw is short of to thickness, doctor can advise that patient does bone increment and performs the operation, i.e. Psoralen or bone grafting, Or use the part that the method recoveries such as Split-crest are thinning, do implant prostheses the most again；From typically Situation considers, 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 accept Minimally Invasive Surgery, " solve disappearance first, Secondly aesthetic requirement " become the demand of more patient.

Summary of the invention

When running into slim alveolar ridge/prominent, it is impossible to use bone increment, this generates and need " treatment in accordance with local conditions " Measure, i.e. " the squeezed technology of pin hole " and therewith of the preparation restricted bed of tooth implant of the present inventor's design Supporting utensil, with the most small wound or without complication realize implantation body storing operation.

The invention of the squeezed device of pin hole bone of the present invention and technology application thereof is compared 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, alveolar ridge crest thickness 4.0mm between two coronas)； 3) implant operation of upper jaw backteeth jaw side seam；4) and other residue alveolar processs or Implants of ridge parietal bone. If the most several situations use existing single traditional planting technology or method all not to accomplish.

For reaching above-mentioned purpose, the technical solution used in the present invention is as follows:

The squeezed device of pin hole bone disclosed by the invention, including the stabilizers sequentially coaxially connected, screw portion, from Tapping portion, the second threaded portion, lead, pointed nose, described stabilizers is cylindrical, described in screw Portion is noncircular cross section cylinder, and the small end in described tapping screw thread portion and the second threaded portion connect, described second Threaded portion is cylinder, and the second threaded portion is provided with external screw thread, and described lead is cylindrical, described tip Portion is prismatic.

The using method of the present invention:

After the Dental Implant recipient bed alveolar ridge determined/prominent top uses pin hole boring, by squeezed for pin hole device Prismatic pointed nose inserts spicule hole, location, and after penetrating bone plane pin hole, turn clockwise squeezed device, its Most advanced and sophisticated Rhizoma Sparganii part has the effect of crowded deep (especially I, II class cortical bone), and beneficially rear portion is led To the insertion of post；Cylinder lead is the part that the squeezed device of pin hole bone plays direction guiding function, by Can move along the direction that pin hole bores in smooth cylinder, without departing from；Second threaded portion be lead with Transition between second threaded portion, has the existence of fine thread (screw thread of the second threaded portion), rotates During squeezed device, fine thread closely embeds cortical bone and is gradually introduced rear portion coarse-pitch thread (screw thread of the second threaded portion), Implement the extruding reaming effect to osseous tissue.Pin hole brill is the first step of reaming, and the squeezed device of pin hole is reaming Second step, the 3rd is that the squeezed device using more large size big uses reaming step by step in order, until be suitable for Implantation body puts into.

Preferably, the radial dimension radial dimension more than stabilizers in portion is screwed described in.

Preferably, the portion of screwing described in 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 cuts Face is circular arc, and the radius of described circular arc is 1.5mm.

Further, the described tapping screw thread portion a diameter of 1.2mm of 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 is adaptive with lead end face, a length of 1mm to 1.5mm of pointed nose.

Further, also include that connecting portion, described connecting portion one end are connected with tapping screw thread portion, connecting portion The other end is connected with the portion of screwing.

Preferably, described connecting portion is cylindrical, and connecting portion is coaxial with tapping screw thread portion.

The method have the advantages that

1. present configuration, 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 rotated；

4. the length difference of connecting portion goes for the squeezed operation of different depth, convenient enforcement.

The most prismatoidal pointed nose, is the function top of the squeezed device of pin hole, acts on one: find flat during location The spicule hole in face；Effect two: rotate squeezed device after penetrating bone plane pin hole, its prismatoidal point Head has the effect of crowded deep (especially I, II class cortical bone), beneficially rear self tapping spiral shell The insertion in stricture of vagina portion；

6. lead is the part that the squeezed device of pin hole bone plays direction guiding function, owing to smooth cylinder is permissible The direction bored along pin hole is moved, without departing from；

7. fine thread (screw thread of the i.e. second threaded portion) is the excessive portion between lead and tapping screw thread portion Point, there is the existence of fine thread, when rotating squeezed device, fine thread closely embeds cortical bone and gradually draws Enter first screw thread at rear portion；

8. tapping screw thread portion has certain cone angle, it is possible to effectively carry out osseous tissue extruding reaming.
