Description
Technical field
The present invention relates to a kind of localizer, particularly a kind of machine for therapeutic instrument for root canal expands pin localizer.
Background technology
Therapeutic instrument for root canal is the main tool that odontologist carries out the patient for there being tooth to suffer from holing, as shown in Figure 2: the boring handle 10 comprising main control system and connect with main control system, be connected to head 11 in the termination of boring handle 10, head 11 be provided with and expand pin 12.Main control system is utilized to drive the turning cylinder in boring handle 10 to rotate during operation, turning cylinder drives expansion pin 12 to rotate, expansion pin 12 is made to rotate into cacodontia inside, the degree of depth pierced is determined by odontologist according to cacodontia situation, after needing the degree of depth entered to determine, just strictly must control the penetration depth expanding pin 12, deeply can damage patient oral cavity if crossed, cross and shallowly do not reach requirement again.Determine that the degree of depth that expansion pin 12 enters utilizes buoy to show at present, namely on expansion pin 12, be set with a buoy 17, buoy 17 equals the degree of depth that will hole to the distance expanding pin 12 termination.This mode is located inaccurate, move because expansion pin 12 enters buoy in tooth body gradually thereupon, can not obviously perceive after when reaching depth requirements, buoy touches tooth end, very easily there is erroneous judgement in the observation completely with operator, buoy 17 also has a certain amount of play relative to expansion pin 12 sometimes.
Summary of the invention
The object of this invention is to provide a kind of accurate positioning, drilling depth controls easily, not occur dark or cross shallow situation, the expansion of the machine for therapeutic instrument for root canal pin localizer that drilling quality is good, overcome the deficiencies in the prior art.
Machine for therapeutic instrument for root canal of the present invention expands pin localizer, comprise the body with side ports, on the inner surface of described body and described therapeutic instrument for root canal, head end outer surface matches, body is connected with limiting plate, be provided with distance adjustment part between body and limiting plate, in the middle part of limiting plate, be provided with opening.
Machine for therapeutic instrument for root canal of the present invention expands pin localizer, and wherein said distance adjustment part structure is outside body, be connected to limit ear, and limit ear is provided with the bolt of axial limiting, and the nut matched with bolt is connected on limiting plate.
Machine for therapeutic instrument for root canal of the present invention expands pin localizer, and there is the plane be parallel to each other the both sides of wherein said side ports, and the distance H between two planes is less than body diameter of bore D.
Machine for therapeutic instrument for root canal of the present invention expands pin localizer, wherein said limit ear comprises the top ear being connected to body outer upper and the following ear being connected to body outer lower portion, top ear and following ear are arranged in the lateral symmetry of body, described bolt inserts in the bolt hole on the ear of top, there is the nut be positioned at above the ear of top bolt upper end, the lower square bolt of top ear is furnished with the screw of axial limiting, in the nut bore on the following ear described in the nut matched with bolt inserts.
Machine for therapeutic instrument for root canal of the present invention expands pin localizer, the head for therapeutic instrument for root canal is sleeved on during use, the nut of rotating bolt upper end, the position of adjustment limiting plate, make limiting plate bottom surface just identical with the degree of depth that will hole apart from the distance expanding pin termination, then drilling operation is carried out when limiting plate contacts with tooth end, drilling depth just reaches requirement, now cannot continue boring again, feel when limiting plate contacts with tooth termination that obviously also drilling depth is accurate, the size determined in boring procedure not easily changes, there is accurate positioning, drilling depth controls to be easy to advantage.

Detailed description of the invention
As shown in Fig. 3 ~ Figure 10: 1 is body, side ports 15 is had in the side of body 1, on the inner surface of body 1 and therapeutic instrument for root canal, head 11 leading section outer surface matches, there is the plane 14 be parallel to each other the both sides of side ports 15, distance H between two planes 14 is slightly less than body 1 hole size D, namely body 1 can be fastened on the leading section of head 11 by side ports 15, because H is slightly less than D, can micro-deformation be there is when body 1 is inserted in, be inserted in after and head 11 fastening.
Outside body 1, be connected to limit ear, limit ear is located at top, the outside place of body 1 and locates below, and namely form top ear 8 and following ear 2, top ear 8 and following ear 2 are all symmetrical set.
Bolt 5 inserts in the bolt hole 13 on top ear 8, and there is the nut 7 be positioned at above top ear 8 bolt 5 upper end.The lower square bolt 5 of top ear 8 is furnished with the screw 6 of axial limiting on two, after two spacing screws 6 screw mutually, axial limiting can be carried out to bolt 5 together with nut 7.The bottom of the nut 4 matched with bolt 5 is fixedly connected with limiting plate 3, is provided with opening 9 in the middle part of limiting plate 3.Nut 4 inserts in the nut bore 16 on following ear 2.
During use, body 1 is sleeved on the leading section of the head 11 for therapeutic instrument for root canal, the expansion pin 12 on head 11 is made just to be positioned at opening 9 on limiting plate 3, the nut 7 of rotating bolt 5 upper end, the position of adjustment limiting plate 3, make limiting plate 3 bottom surface just identical with the degree of depth that will hole apart from the distance expanding pin 10 front end, then drilling operation is carried out when limiting plate 3 contacts with tooth end, drilling depth just reaches requirement, now cannot continue boring again, feel when limiting plate contacts with tooth termination that obviously also drilling depth is accurate, the size determined in boring procedure not easily changes, there is accurate positioning, drilling depth controls to be easy to advantage.
