Abstract
The utility model discloses medical apparatus and instruments, and particularly relates to a novel dentagra. A piston cavity and a pressure supply passageway are arranged inside a hand shank, wherein the pressure supply passageway is communicated with the piston cavity. A medium inlet is arranged at the tail end of the hand shank. A piston is arranged inside the piston cavity. A piston rod is arranged at the front end of the piston. A movable tong door is arranged at the front end of the piston rod. The hand shank is fixedly provided with a fixing tong door through a dentagra arm. The hand shank is further provided with a pressure gage which is communicated with the piston cavity. A switch is arranged inside the pressure supply passageway. The novel dentagra is novel in structure and design, convenient to operate, time-saving and energy-saving, and has remarkable practicality.
Description
Technical field
This utility model belongs to medical apparatus and instruments, especially is a kind of novel dental forceps.
Background technology
Dental forceps is dentistry apparatus comparatively commonly used, usually is made of handle, jaw and fixed axis.Present dental forceps in use, the handle of need to holding with a firm grip on the one hand, make jaw clamping tooth firm, also to firmly tooth be extracted from dental bed on the other hand, this has just increased the difficulty of operation greatly, be easy to make jaw to break away from tooth, need smoothly exodontia of multi-pass operation, bring very large inconvenience to medical work.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure, easy to operate that this utility model provides, and adopts hydraulic pressure or air pressure to drive the Novel dental forceps of jaw clamping.
For realizing above-mentioned technical purpose, this utility model is realized by the following technical solutions: a kind of Novel dental forceps, be provided with a handle, be provided with plunger shaft in the handle and reach the pressure passageway that supplies that communicates with it, the handle tail end is provided with and the medium inlet that communicates for pressure passageway, be provided with piston in the plunger shaft, piston nose is provided with piston rod, the piston rod front end is provided with moving jaw, handle is fixed with a regular jaw that is positioned at moving jaw the place ahead by tong arm, regular jaw is vertical with handle with the clamping face of moving jaw, is provided with in addition the piezometer that communicates with plunger shaft on the handle, is provided with switch in the pressure passageway.
The utlity model has following beneficial effect: during use, the medium inlet connects external pressure or pressure hydraulic generator, under the driving of hydraulic pressure or air pressure, the piston actuated moving jaw moves to regular jaw, realize holding function, the exodontia operation can be realized by handle, the clamping dynamics can be held by switch and piezometer.Its structural design is novel, and is easy to operate, time saving and energy saving, has significant practicality.
Description of drawings
Accompanying drawing is this utility model structural representation.
Among the figure, 1, the medium inlet, 2, switch, 3, piezometer, 4, piston rod, 5, tong arm, 6, regular jaw, 7, moving jaw, 8, handle, 9, piston, 10, for pressure passageway, 11, plunger shaft.
The specific embodiment
Shown in accompanying drawing, the voltage supply path 10 that is provided with plunger shaft 11 in the handle 8 and communicates with it, handle 8 tail ends are provided with the medium inlet 1 that communicates with the voltage supply path 10, be provided with piston 9 in the plunger shaft 11, piston 9 front ends are provided with piston rod 4, piston rod 4 front ends are provided with moving jaw 7, handle 8 is fixed with a regular jaw 6 that is positioned at moving jaw 7 the place aheads by tong arm 5, regular jaw 6 is vertical with handle 8 with the clamping face of moving jaw 7, be provided with in addition the piezometer 3 that communicates with plunger shaft 11 on the handle 8, be provided with switch 2 in the voltage supply path 10.
