Description

Articulating device

This utility model belongs to the medical sanitary apparatus field, a kind of improved occludator that is used for the upper and lower jaw plaster model of clamping of more specifically saying so.

The occludator that generally uses both at home and abroad is by the upper jaw member support at present, lower jaw member support and rear support stand constitute, lower jaw member support and rear support stand are one, be fixed with a bow beam made from fine steel tube on the rear support stand, the two ends of bow beam are sleeved on two cheese head screws on the rear support stand, can rotate, bow beam and upper jaw member support are connected with spring in the centre position, the left side of upper jaw member support, on right two arms guide groove is arranged, and cooperate with two clamp nuts on being arranged on rear support stand, upper jaw member support front portion is passed by incisal guidance pin and is vertical with its maintenance, and the incisal guidance pin lower end is positioned at the incisal guidance table of lower jaw member support front end.This structure can be simulated and the similar mandibular movement of oral cavity masticatory movement, and keeps the mutual relation of upper and lower jaw plaster model.During use, transfer and mixed Gypsum Fibrosum, with upper and lower gnathode, be separately fixed at by jaw relationship on the upper jaw member support and lower jaw member support of occludator, after using up, also to take off plaster model from occludator, and the Gypsum Fibrosum after solidifying is bonded together plaster model and upper and lower jaw body support frame securely, rarely causes very easily accidentally that plaster model fractures, fragmentation, and time-consuming, effort.

The purpose of this utility model provide a kind of easy to use, jaw body plaster model installing/dismounting is simple, clamping is firm and can imitate the improved occludator of oral cavity masticatory movement.

This utility model is achieved in that a kind of occludator, divide the upper jaw member support, lower jaw member support and rear support stand, lower jaw member support and rear support stand are one, the key problem in technology of its solution is on the upper jaw member support upper fixed seat to be arranged, on the lower jaw member support lower fixed seat is arranged, square elevating lever passes the square hole on the upper fixed seat and is regulated fixing by trip bolt, be connected for ball-joint between upper jaw member fixture and the elevating lever and between lower jaw member fixture and the lower fixed seat, upper jaw member fixture and lower jaw member fixture have preceding jaw respectively, rear clip-claw, tightening knob, dog screw, mould plate and be fixed on the mould plate bottom surface and constitute the trough plate of square cavities with it, respectively be with a vertical with it square core bar on preceding jaw and the rear clip-claw, respectively before square cavities, insert the rear end, one end of preceding jaw core bar is made one section thin bolt, load onto tightening knob after passing rear clip-claw core bar and rear clip-claw behind the cover upper spring above, dog screw is arranged on the trough plate sidewall.

Be described in detail this utility model below in conjunction with accompanying drawing.

Accompanying drawing is the steady figure of a kind of concrete structure signal of this utility model.

In conjunction with the accompanying drawings, upper jaw member support 20 is equivalent to human body upper jaw part, and front end is passed by incisal guidance pin 4 and be perpendicular, incisal guidance pin 4 lower ends are positioned at lower jaw member support 9 front end incisal guidance tables 5, incisal guidance pin 4 can freely take off, and is used to keep the normal height of upper and lower jaw body, and rises and support and positioning action.Upper jaw member support 20 rear portions have two arms, have guide groove 15 on the arm, and cooperate with the clamp nut 16 that is arranged on both sides, rear support stand 13 upper end, upper jaw member support 20 can serve as that axle rotates with the axis of two relative clamp nuts 16 like this, can when unclamping clamp nut 16, slide again, can simulate the masticatory movement of human body lower jaw along guide groove 15 front and back.Lower jaw member support 9 is an one with rear support stand 13.

Upper fixed seat 23 is arranged on the upper jaw member support 20, lower fixed seat 11 is arranged on the lower jaw member support 9, both are on same axis, upper fixed seat 23 together has square hole together with upper jaw member support 20, upper fixed seat 23 sidewalls are provided with trip bolt 19, square elevating lever 22 passes square hole and is also fixed by its height of trip bolt 19 adjustings, be connected for ball-joint between upper jaw member fixture and the elevating lever 22 and between lower jaw member fixture and the lower fixed seat 11, upper jaw member fixture and lower jaw member fixture have preceding jaw 3 respectively, rear clip-claw 12, tightening knob 18, dog screw 14, mould plate 2 and be fixed on the mould plate bottom surface and constitute the trough plate 1 of square cavities with it, respectively be with a vertical with it square core bar 17 on preceding jaw 3 and the rear clip-claw 12, respectively before square cavities, insert the rear end, one end of preceding jaw 3 core bars 17 is made one section thin bolt, load onto tightening knob 18 after passing rear clip-claw 12 core bars 17 and rear clip-claw 12 behind the cover upper spring above, unclamp tightening knob 18 and can make front and

back jaw

3,12 distances increase, grip bigger plaster model, before screwing tightening knob 18 and can using, rear clip-

claw

3,12 distances are dwindled, grip less plaster model, dog screw 14 is arranged on trough plate 1 sidewall, when the good plaster model of clamping and after screwing tightening knob 18, fastening again dog screw 14 can further increase the fastness of clamping, prevents to become flexible.

Ball-joint connecting device between upper jaw member fixture and the elevating lever 22 comprises the club 6 that is fixed on trough plate 1 bottom surface, is enclosed within the cover 10 on the ball 7 and penetrates elevating lever 22 endoporus and is sleeved on the ball seat in its bottom and is screwed in the fastening screw 21 at elevating lever 22 tops, elevating lever 22 bottoms with overlap 10 between the spiral shell level be connected.When opening fastening screw 21, mould plate 2 can be done the omnibearing tilt adjustment by ball-joint, tightens fastening screw 21, and mould plate 2 can be fixed on any one selected position, makes the interlock between the upper and lower jaw plaster model meet jaw relationship.

Ball-joint connecting device between lower jaw member fixture and the lower fixed seat 11 comprises the club 6 that is fixed on trough plate 1 bottom surface, is enclosed within on the ball 7 and with handles 8 cover 10 and lower fixed seat 11, the upper surface of lower fixed seat 11 is a ball seat, outer threaded and with cover 10 between be threaded, same with the upper jaw member fixture, the lower jaw member fixture also can be done the omnibearing tilt adjustment by ball-joint.

During use, the upper and lower jaw plaster model that trims is placed on respectively between the preceding jaw 3 and rear clip-claw 12 of upper and lower jaw body fixture, the bottom surface is placed on the mould plate 2, at first according to biteplane adjustment model plate 2, fixed after suitable, according to length, the width of plaster model base, regulate the position, all around again, tighten tightening knob 18, dog screw 14 after suitable.

When need adjusting the upper jaw member fixture, can unclamp trip bolt 19 with respect to the height of lower jaw member fixture, on carry (or decline) bar 22, highly suitable after, tighten trip bolt 19.

It is convenient, reliable to the utlity model has rational in infrastructure, clamping plaster model, is easy to adjust the jaw relationship of plaster model, can guarantee its integrity when pulling down plaster model, has overcome the problem that the plaster fixation model makes the model rapid wear.
