Abstract
The utility model relates to a medical apparatus, in particular to a raiser inside the sinus maxillaries, which has simple and flexible operation as well as high security and is provided with a rod-shaped body. The raiser is characterized in that the upper end of the body is provided with a collision strut; the head part of the collision strut is provided with a groove; a positioning sleeve is arranged on the collision strut, and a locking device is arranged on the positioning sleeve; a lower bone plate of the sinus maxillaries can be conveniently and flexibly impacted and chiseled. Since a smaller included angle is formed between the collision strut and a handle body, the collision strut can move flexibly in a planting nest, the all-wave operation from every angle is convenient, and the motion space is large. By adding the positioning sleeve, the phenomenon of perforation for sinus maxillaries lower mucosa is not easy to occur in the sinus maxillaries lower lifting operation. The raiser inside the sinus maxillaries has the advantages of simple structure, convenient operation, flexibility, high safe performance, little damage and effective sinus maxillaries inner lifting.
Description
Technical field:
This utility model relates to medical apparatus, the interior lifter of specifically a kind of maxillary sinus easy to operate, flexible, that safety is higher.
Background technology:
Along with science and technology development, the raising of people's living standard, the tooth-planting technology obtains fast development and extensive use.But because analysis for maxillary sinus bony is often thinner, for guaranteeing the plantation quality, often need the low bone of maxillary sinus is thickened, lifter shape Chang Weiyi is similar shaft-like with plantation nest diameter, and the working end is the recessed head of circle.During use, insert in the plantation nest working end, and the handle end that pounds with a hammer promotes.Its shortcoming of this kind lifter is that maneuverability is poor, and it is less to cause analysis for maxillary sinus bony to promote amplitude, and the Dental Implant effect is undesirable, in addition, knocks and more easily causes hole to hang down the mucosa breakage in the lifting process, increases the risk and the difficulty of plantation.
Summary of the invention:
This utility model purpose is to overcome the deficiency of the technical ability of above-mentioned existence, provide a kind of novel easy and simple to handle, safety is higher, effective lifter in the maxillary sinus that promotes of analysis for maxillary sinus bony.
This utility model reaches by following measure:
Lifter in a kind of maxillary sinus is provided with shaft-like body, it is characterized in that the body upper end is provided with impact bar, the impact bar head is provided with groove, and impact bar is provided with positioning sleeve, and positioning sleeve is provided with locking device, can impact and cut a hole the low hone lamella of disconnected maxillary sinus easily and flexibly, and the easy damaged maxillary sinus does not hang down mucosa.
The relative body of this utility model impact bar is inclined, and angle to enlarge the activity space of impact bar head, effectively improves the lifting of the low hone lamella of maxillary sinus at 10 °-20 ° between impact bar axis and body axis.
This utility model positioning sleeve adopts with impact bar and is threaded, and locking device adopts screw, also can adopt locking nut.
This utility model impact bar head diameter can increase impact bar head movement scope greater than bar portion diameter, impacts the low hone lamella of maxillary sinus effectively.
This utility model can impact cutter knochenbruch matter easily and flexibly, owing to set up positioning sleeve, do not break through maxillary sinus chamber phenomenon in operation, the activity space of impact bar its head in the plantation nest is big, improved the lifting amplitude of analysis for maxillary sinus bony, so that implantation body is more firm, have advantages such as simple in structure, easy to operate, that safety is good, bone grafting is effective.
Description of drawings:
Fig. 1 this utility model structural representation.
The specific embodiment:
In conjunction with the accompanying drawings this utility model is further described:
Shown in Figure 1, lifter in a kind of maxillary sinus, be provided with shaft-like body 1, body 1 adopts cylindrical, also can adopt prismaticly, and two ends are equal diameters, also can be that equal diameter does not have certain tapering, body 1 upper end is provided with impact bar 2, and impact bar 2 relative bodies 1 are inclined, and angle is generally at 10 °-20 ° between impact bar 2 axis and body 1 axis, preferably 15 °, impact bar 2 heads are provided with groove, are convenient to cutting cutter knochenbruch plate, are provided with positioning sleeve 3 on impact bar 2, positioning sleeve 3 adopts with impact bar 2 and is threaded, positioning sleeve 3 is provided with locking device 4, and locking device 4 adopts screw, also can adopt locking nut.This utility model impact bar head diameter can increase impact bar head movement scope, the lifting that has effectively improved analysis for maxillary sinus bony greater than bar portion diameter.
