Abstract

The utility model relates to a medical instrument, in particular to a maxillary sinus lifting osteotome. The purpose is to provide a maxillary sinus lifting osteotome with low impact force, less rupture of sinus membrane and regular opening of sinus bottom. The utility model comprises a handle and a working end. The working end is provided with a conical pit, and the inner periphery of the pit is a circular knife edge. It can be knocked 3mm away from the sinus floor, and the patient feels slight discomfort; the edge of the maxillary sinus membrane is regularized by the bone column pressing and lifting, and various diameters of 2.2-5mm can be used according to the shape of the implant or the sinus floor; due to the cutting and pushing of the sinus floor The bone block is conical and cylindrical, and the stress is raised along the angle of the chisel wall with the sinus membrane, and the damage of the sinus membrane may be extremely small; the oblique hole groove can reduce the friction between the osteotome and the bone wall, and relieve the work of the bone block caused by negative pressure adsorption. Concave top impaction; autologous bone preservation and bicortical fixation can be achieved after implantation, and can be repaired 3-4 months after surgery.

Description

Osteotome is promoted in maxillary sinus

Technical field

The utility model relates to a kind of medical instrument, osteotome is promoted in specifically a kind of maxillary sinus.

Background technique

In modern tooth-planting technology, maxillary sinus region in alveolar ridge lift technique because the small implantation primary stability of wound compared with Good feature is more come to be planted doctor's attention by various countries.It is conventional that through crest of alveolar ridge maxillary sinus disease, there are two main classes:

One kind is that the method for rushing to summit promotes maxillary sinus inner membrance indirectly.Using the Summers scrobicula osteotome of invention in 1994 as representative, or The similar osteotomes blunt forces of shape impact Sinus floor, cause the cortex bone greendstick fracture of sinus bottom, and then Sinus floor is made to fracture Then piece is put into the mixtures such as bone meal and blood in plantation channel and pushes into maxillary sinus together with sinus bottom mucous membrane upward displacement, To promote Sinus floor mucous membrane.This method advantage is that osteocomma band film is promoted, and has autologous bone preservation；The disadvantage is that being caused to brain Sharp pounding, patient perceptions' reflection is poor, and bottom forming hole form is irregular, and initial stage implantation stability is poor, and bone fragment is easy thorn Broken sinus film, preparatory hole spacing sinus bottom are greater than particularly evident when 2mm.The country, which represents, Chu Deguo osteotome method.

Another kind of is that removing method directly promotes maxillary sinus inner membrance.There is disk to bore removing method, diamond dust round bur removing method etc..Operation It is middle to abrade Sinus floor bone plate until adding close to maxillary sinus film with the technologies such as sinus film stripping device or sacculus, hydraulic pressure with low speed bone drill Directly promote maxillary sinus film.This method advantage is that patient suffering is small, sinus bottom is regular at pore morphology, the disadvantage is that low speed abrades sclerotin Bone easily occurs to burn, it is desirable that stringent water cooling and assurance brill are deep, and blind view ejection removing sinus film requires feel sensitive.Height of alveolar ridge exists It is not easy to grasp when 5-8mm.The country, which represents, has Zhao Baodong disk to bore method.

Summary of the invention

In one kind that the purpose of the utility model is to provide a kind of impact forces is small, sinus film is not easily broken, the aperture of sinus bottom is regular Osteotome is promoted in jaw sinus.

The utility model includes handle and working end, and working end is equipped with pyramid type pit, and pit inner periphery is circular ring shape Blade；It is communicated up to rare inclined hole slot with pit bottom in outer side wall.

Above-mentioned working end can have the symmetrical two inclined holes slot of cheek-tongue side on outer side wall, communicate respectively with pit bottom.

Deep 2~the 3mm of above-mentioned pit, inner wall smooth, blade inner bevel degree are 4~6 degree, bottom wall thickness for 0.5~ 0.6mm。

The sword end thickness 0.3mm polishing of above-mentioned blade is gradually as thin as 0.2mm.

Above-mentioned inclined hole slot diameter is 1~1.5mm, 6~7mm of inclined hole flute length.

Above-mentioned working end is best are as follows: pit depth 3mm, blade inner bevel degree are 5.7 degree, bottom wall thickness 0.6mm, tiltedly The 2.5mm aperture of hole slot pitch blade end, inclined hole flute length 6mm.

Above-mentioned handle can be crank type.

Above-mentioned handle can be staight shank type.

Production has 8,10,13,15mm scale on above-mentioned working end lateral wall.

The utility model has the following advantages compared with prior art:

The utility model rushes to summit working mechanism by changing Summers Osteotome blunt forces as circle sword cutting sinus bottom bone block Band film low force extrudes repeatedly afterwards;Working end cuts circle sword thickness and is gradually as thin as 0.2mm by 0.3mm polishing, ensure that sword end intensity； It bores bone depth to control without stringent, apart from sinus bottom, 3mm, which can be tapped, rushes to summit, and cutting type taps the encephalic vibratory sensation that alveolar ridge generates Slightly；It is circular cone cylindricality that sinus bottom bone block is pushed in cutting, and stress is jacked up along chisel wall angle to outside upper band sinus film, and the breakage of sinus film may pole It is small；Osteotome lateral wall diagonal hole slot reduces osteotome and bone wall friction, falls through and feels clear, sinus bottom bone block of rushing to summit will not be inhaled because of negative pressure In attached insertion osteotome work concave crown, ejection bone block can be looked into along inclined hole trenching with spherical probes；According to implant base diameter or sinus bottom Form can be selected different-diameter osteotome and rush to summit sinus bottom, and minor diameter paring gouge is suitable for single nail plantation and oblique domatic sinus bottom of rushing to summit； 4.5mm or more paring gouge is rushed to summit 1-3mm alveolar ridge, is added with the near and far range removing sinus film of a variety of further ejections of sinus film stripping device, Only drilling no longer needs to rush to summit for adjacent teeth implantation；Different-diameter osteotome can be selected according to implant base diameter or sinus bottom form to rush to summit sinus Bottom, minor diameter paring gouge are suitable for single nail plantation and oblique domatic sinus bottom of rushing to summit；4.5mm or more paring gouge is rushed to summit 1-3mm alveolar ridge, is added Sinus film is removed with the near and far range of a variety of further ejections of sinus film stripping device, only drilling no longer needs to rush to summit for adjacent teeth implantation；Plant nest Bottom maxillary sinus film strips have autologous bone column to save support, insert PRR or artificial collagen membrane block, and skeletonization excellent is reduced Bone meal filling；Single planting body is implanted with double cortex fixed effects, can repair the postoperative 3-4 month.
