Abstract
The open a kind of implantation body's extractor that ruptures of this utility model, by round bur and anti-silk, drill bit is supporting forms, one end of round bur is universal joint and the other end is corundum bulb, and one end of anti-silk drill bit is universal joint or hex nut and the other end is anti-silk operate portions.This utility model adopts kit, round bur perforate, the dextrorotation of anti-silk drill bit is taken out, can conveniently rupture implantation body take out, the damage that taking-up mode is caused drops to minimum, avoid the damage to growing area osseous tissue, after taking-up, can directly carry out implantation body's implant surgery at former growing area, be convenient to clinician's operation.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of implantation body's extractor that ruptures.
Background technology
In prior art, fracture implantation body removing method roughly comprises two kinds:
One, use the annular larger than stress to get bone drill, after directly bone regeneration around implant osseous tissue being cut off, take out, shortcoming is that wound is larger, large to osseous tissue damage range, and is irreversible damage;
Two, due to the impossible complete level of fracture implantation body section, use after fluted drill guiding perforate, re-use positive silk and split brill derotation taking-up, location lacks accuracy, and synosteosis strength is larger, and positive splits brill derotation strength deficiency.
Along with constantly popularizing of planting technology, later maintenance will become clinical groundwork gradually, because causing implantation body, machinery and load effect in osseous tissue, occur that fracture also will constantly occur, be necessary that safety is taken out fracture implantation body as far as possible in the situation that reducing osseous tissue damage, for follow-up plantation provides enough implant beds.
Therefore, the inventor develops a kind of implantation body's extractor that ruptures specially, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of implantation body's extractor that ruptures, and to facilitate fracture implantation body to take out, avoids the damage to growing area osseous tissue.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of fracture implantation body extractor, by round bur and anti-silk, drill bit is supporting forms, and one end of round bur is universal joint and the other end is corundum bulb, and one end of anti-silk drill bit is universal joint or hex nut and the other end is anti-silk operate portions.
The centre of described round bur is brake hoop.Wherein, corundum bulb diameter is 1.2 millimeters, and universal joint diameter is that 2 millimeters and length are 5 or 7 millimeters, and brake hoop diameter is that 5 millimeters and length are 5 millimeters.
The centre of described anti-silk drill bit is connecting rod.Wherein, anti-silk operate portions length is that 10 millimeters and maximum gauge are 5 millimeters, and connecting rod length is 5 millimeters.
When one end of described anti-silk drill bit is hex nut, be equipped with die nut.
Adopt after such scheme, when this utility model uses, first use the corundum bulb of round bur in fracture implantation body plane of disruption central punch, then use anti-silk drill bit, manually or machine dextrorotation, just can take out like a cork fracture implantation body, like this, this utility model adopts kit, round bur perforate, and the dextrorotation of anti-silk drill bit is taken out, the damage that taking-up mode is caused drops to minimum, avoid the damage to growing area osseous tissue, after taking-up, can directly carry out implantation body's implant surgery at former growing area, be convenient to clinician's operation.
Below by embodiment and accompanying drawing, this utility model is had been described in detail.
Brief description of the drawings
Fig. 1 is the three-dimensional exploded view of this utility model embodiment;
Fig. 2 is the three-dimensional exploded view of another embodiment of this utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, the one fracture implantation body extractor that this utility model discloses, by round bur 1 and anti-silk, drill bit 2 is supporting forms.
One end of round bur 1 be universal joint 11 for connecting with the power section (such as dentist's drill bit motor transmission shaft) of medical apparatus and instruments, and the other end is corundum bulb 12.For handled easily, the centre of round bur 1 is brake hoop 13.Optimal design is: corundum bulb 12 diameters are 1.2 millimeters, and universal joint 11 diameters are that 2 millimeters and length are 5 or 7 millimeters, and brake hoop 13 diameters are that 5 millimeters and length are 5 millimeters, can select according to different depth the round bur 1 of different size when use.
One end of anti-silk drill bit 2 is that universal joint 21 is for connecting and carry out mobile operation (as shown in Figure 2) with the power section (such as dentist's drill bit motor transmission shaft) of medical apparatus and instruments, or one end of anti-silk drill bit 2 is hex nut 22, can be equipped with again die nut 3 and carry out manual operation (as shown in Figure 1), and the other end is anti-silk operate portions 23.For handled easily, the centre of anti-silk drill bit 2 is connecting rod 24.Optimal design is: anti-silk operate portions 23 length are that 10 millimeters and maximum gauge are 5 millimeters, and connecting rod 24 length are 5 millimeters.
When this utility model uses, first the universal joint of round bur 1 11 is connected with the power section of medical apparatus and instruments, drive the corundum bulb 12 of round bur 1 to rotate by the power section of medical apparatus and instruments, in fracture implantation body plane of disruption central punch.Then use anti-silk drill bit 2 instead, if motor-driven anti-silk drill bit 2 just connects the universal joint 21 of anti-silk drill bit 2 with the power section of medical apparatus and instruments, drive the anti-silk operate portions 23 of anti-silk drill bit 2 to rotate by the power section of medical apparatus and instruments, the anti-silk of dextrorotation drill bit 2, just can take out fracture implantation body; If manual anti-silk drill bit 2 just coordinates with hex nut 22 with die nut 3, the manually anti-silk of dextrorotation drill bit 2, just can take out fracture implantation body.
