Detailed description of the invention
Below in conjunction with accompanying drawing, introduce this utility model embodiment in detail.
Consult Fig. 1, this utility model provides a kind of implantation body to take out instrument, for taking out implantation body 1, comprise positioning protective sleeve 2 and central bolt 4, the lower end of positioning protective sleeve 2 be provided with can be inserted in implantation body 1 upper surface shoulder hole in and the positioning boss 2a positioned, upper end is offered large at the upper surface of positioning protective sleeve 2, the shoulder hole centre bore 2b that lower end is little, this centre bore 2b runs through positioning boss 2a downwards, central bolt 4 is set in this centre bore 2b, and the positioning step 2c be provided with in centre bore 2b for carrying out axial location to this central bolt, this positioning step is inclined-plane,
The two ends of above-mentioned central bolt 4 all extend to outside positioning protective sleeve 2, the top of central bolt 4 is provided with tightens portion 4a, spanner tightens by being set in this rotation portion realized to central bolt, therefore this portion of tightening can be the common shape such as rectangle or regular hexagon, also can be quincunx other shapes such as grade; The threaded body 4b corresponding with the female thread in implantation body is provided with in the lower end of central bolt 4.
Above-mentioned instrument can be used when implantation body's inner bolt does not rupture, when screw extraction in implantation body, central bolt 4 is replaced by cutter, this cutter is provided with the positioning table corresponding with positioning step 2c, and cutter comprises the first cutter 3a and the second cutter 3b, first cutter is the fluted drill for holing, and the second cutter is cutter tooth rotation direction with the external thread rotary of the screw in implantation body 1 to contrary screw tap.This cutter comprises connecting axle and is fixed on the cutter body of connecting axle end, and connecting axle can be set in centre bore 2b and end face contacts with positioning step 2c thus realizes axial location.
Positioning step 2c in the present embodiment is greater than the distance of positioning table to tool nose to the distance of the screw head in implantation body 1, and namely cutter cannot penetrate the screw that really ruptures, therefore can only at the drilling blind hole on screw that ruptures.
Use above-mentioned taking-up instrument, take out the method for implantation body and bolt, comprise the following steps:
A, sterilization, take out instrument to the whole series and carry out high temperature or alcohol disinfecting; Comprise cutter, central bolt and positioning protective sleeve, avoid bringing into the oral cavity such as antibacterial;
B, location, be sheathed with the positioning boss of positioning protective sleeve 2 lower end in the shoulder hole in implantation body 1, realize the location and installation between protective sleeve 2 and implantation body 1;
C, inspection, check in implantation body whether have fracture screw, according to checking whether the taking-up scheme that there is fracture screw and feel to adopt;
When without fracture screw, then perform implantation body's removal process, this implantation body's removal process comprises step D to step e;
When there being fracture screw, then perform fracture screw removal process, this fracture screw removal process comprises step F to step I;
D, fixing, be sheathed with by central bolt in centre bore, Rotation of central bolt makes threaded body be screwed in the female thread of implantation body, realizes being fixedly connected with between central bolt with implantation body;
E, implantation body take out, and reversely rotate central bolt, drive implantation body to rotate, until take out whole implantation body and complete implantation body's removal process; Cleaning and sterilizing is carried out to positioning protective sleeve and cutter simultaneously, use in order to next time.
It is below the removal process of fracture screw;
F, boring, be inserted in the cutter with fluted drill in the cutter holes of positioning protective sleeve 2, and hole (blind hole) to the fracture screw in implantation body 1 with fluted drill, until cutter connecting axle contacts with positioning step, takes out fluted drill after completing boring; Due to positioning step 2c to fracture screw head distance be greater than the distance of positioning table to tool nose, therefore, fracture screw on boring be blind hole; In order to improve grasp, in the present embodiment, the degree of depth is more than or equal to 2mm;
G, tapping, be inserted in the cutter with screw tap in the centre bore of positioning protective sleeve 2, and carry out tapping with screw tap to the hole got out in step F;
H, taking-up screw, cutter continues to rotate after completing tapping, namely when the head of screw tap contacts with the bottom surface in hole, now between screw tap and break bolt, nothing relatively rotates, fracture screw and cutter are rotated simultaneously, because the cutter tooth rotation direction of screw tap and the external thread rotary of fracture screw 1a are to contrary, after completing tapping, screw tap is rotated further until taken out from implantation body by fracture screw;
I, execution implantation body removal process, namely
D, fixing, be sheathed with by central bolt in centre bore, Rotation of central bolt makes threaded body be screwed in the female thread of implantation body, realizes being fixedly connected with between central bolt with implantation body;
E, implantation body take out, and reversely rotate central bolt, drive implantation body to rotate, until take out whole implantation body and complete implantation body's removal process; Cleaning and sterilizing is carried out to positioning protective sleeve and cutter simultaneously, use in order to next time.
In order to improve precision, avoid the torque of employing excessive and affect implantation body or the taking-up of fracture screw, in step D or step e or step G or step H, employing torque spanner is turning tool.
This utility model implantation body takes out instrument, and implantation body is fast convenient to remove, farthest can reduce misery and the loss of patient, avoid human and material resources, financial resources and leeway, reduces doctor-patient dispute, is also conducive to carrying out of Dental Implant technology.
