Abstract
This utility model discloses the complete column bone drill of a kind of standardization and gets device, getting bone drill, latch and knockout pin by annular forms, one end that annular is got bone drill is universal joint and the other end is hollow ring drill bit, in the sidewall of hollow ring drill bit, offer axial groove, knockout pin interts in hollow ring drill bit, on knockout pin, form radially jack, latch interts in the radially jack of the axial groove of hollow ring drill bit and knockout pin.This utility model can obtain enough clinical complete column bones that needs length.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly the complete column bone drill of a kind of standardization is got device.
Background technology
In prior art, the obtaining of column bone all adopts annular to get bone drill and realizes, but, due to the special structure of osseous tissue, it is the anatomical features of cortical bone-spongy bone-cortical bone, while making column bone slightly long, be difficult to completely from ring bone drill, take out, thereby cannot obtain longer column bone, affected the effect of wishing simultaneously to provide in the time completing bone defect repair by autologous column bone retention.
Utility model content
The purpose of this utility model is to provide the complete column bone drill of a kind of standardization to get device, to obtain enough clinical complete column bones that needs length.
In order to reach above-mentioned purpose, solution of the present utility model is:
The complete column bone drill of a kind of standardization is got device, getting bone drill, latch and knockout pin by annular forms, one end that annular is got bone drill is universal joint and the other end is hollow ring drill bit, in the sidewall of hollow ring drill bit, offer axial groove, knockout pin interts in hollow ring drill bit, on knockout pin, form radially jack, latch interts in the radially jack of the axial groove of hollow ring drill bit and knockout pin.
Shape radially jack in a row on described knockout pin, is applicable to select different column bone height according to different situations.
On described hollow ring drill bit, form and bore tooth.
On described hollow ring drill bit, offer vertically two groups of axial grooves.
Adopt after such scheme, when this utility model uses, annular is got to the universal joint of bone drill and the power section of medical apparatus and instruments connects, power section drives annular to get bone drill rotation and bores bone thus, and the column bone in hollow ring drill bit promotes knockout pin and moves inward, in the time that knockout pin cannot move inward again, stop the rotation that power section and annular are got bone drill, relend and help latch that knockout pin is outwards promoted, the column bone drilling through can be released from hollow ring drill bit, realize and get bone.This utility model, by regulating the shift motion of knockout pin in hollow ring drill bit, can obtain enough clinical complete column bones that needs length, thereby reach, implantation body implants and the object of the column bone implantation same period.
Below by embodiment and accompanying drawing, this utility model is had been described in detail.
Brief description of the drawings
Fig. 1 is three-dimensional exploded view of the present utility model;
Fig. 2 is combination schematic diagram of the present utility model;
Fig. 3 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 complete column bone drill of a kind of standardization that this utility model discloses is got device, gets bone drill 1, latch 2 and knockout pin 3 form by annular.
One end that annular is got bone drill 1 is that universal joint 11 can connect with the power section of medical apparatus and instruments (such as dentist's drill bit motor transmission shaft), and the other end is hollow ring drill bit 12, in the sidewall of hollow ring drill bit 12, offer axial groove 13, for ease of assembly and be convenient to bone bits and derive, on hollow ring drill bit 12, offer vertically two groups of axial grooves 13, for the ease of boring bone, on hollow ring drill bit 12, form and bore tooth 14.
Knockout pin 3 interts in hollow ring drill bit, forms radially jack 31 on knockout pin 3.This utility model can be equipped with the knockout pin 3 of different length, for drilling through the column bone of different length, also can be as shown in Figure 3, shape radially jack 31 in a row on knockout pin 3, select different radially jacks 31 to coordinate with aftermentioned latch 2, applicable to the column bone that drills through different length.
Latch 2 interts in the axial groove 13 of hollow ring drill bit 12 and the radially jack 31 of knockout pin 3.
When this utility model uses, selecting suitable knockout pin 3 to be contained in annular gets in bone drill 1, the universal joint 11 of annular being got to bone drill 1 connects with the power section of medical apparatus and instruments, power section drives annular to get bone drill 1 rotation and bores bone thus, bore in bone process, column bone in hollow ring drill bit 12 promotes knockout pin 3 and moves inward, when knockout pin 3 is restricted cannot move inward time again, stop the rotation of power section, annular is got bone drill 1 and is also stopped operating, relend and help latch 2 that knockout pin 3 is horizontally outward promoted, the column bone drilling through can be released from hollow ring drill bit 12, obtain enough clinical complete column bones that needs length, Level Promoting can reduce column bone and the friction that encircles bone drill inwall.
Feature of the present utility model is: latch 2 plays the effect of releasing column bone and measuring column bone length simultaneously, the diameter of knockout pin 3 can be got bone drill 1 according to annular and determine, this utility model is conducive to clinical combination Gong Gu district anatomical structure, saferly obtains exactly complete column bone.
