Abstract
The utility model relates to small-jaw dental forceps with a support. The small-jaw dental forceps with the support are characterized in that a protruded fulcrum is arranged at the front end of a lower forceps plate, a bent lower forceps jaw arm fulcrum is arranged near the front end on a lower forceps jaw arm and is connected with a fulcrum shaft via a hinge pin, the front end of the lower forceps jaw arm is a forceps jaw which is connected with a central shaft of an upper forceps jaw via a hinge pin, the upper end of the upper forceps jaw is connected with a front-end shaft of an upper forceps jaw arm via a connection shaft, the position near the front end of the upper forceps jaw arm is pressed on the lower forceps jaw arm fulcrum, and a support reset spring is arranged between the tail ends of the lower forceps jaw arm and the upper forceps jaw arm. By adding the lower forceps plate below the dental forceps to supply fulcrum for the dental forceps, a healthy tooth is free of being taken as the fulcrum, so that damage to the healthy tooth is avoided.
Description
Technical field
This utility model relates to a kind of small forceps mouth dental forceps of belt supporting frame, is applied to dentistry.
Background technology
The instruments for tooth extraction that generally uses at present all be with healthy tooth as the fulcrum exodontia, bring infringement to healthy tooth, and patient's misery is larger when having tooth pulled out.
Summary of the invention
The purpose of this utility model provides a kind of anodontia fulcrum dental forceps, and it comes for dental forceps provides fulcrum by increase a nipper plate under dental forceps, need not bring infringement to healthy tooth take healthy tooth as fulcrum.
The technical solution of the utility model is achieved in that the small forceps mouth dental forceps of belt supporting frame, it is characterized in that: the front end of nipper plate has the fulcrum of projection, the inclined to one side front end of lower clamp nozzle arm has forniciform lower clamp nozzle arm fulcrum and is connected with fulcrum shaft by bearing pin, lower clamp nozzle arm front end is jaw, be connected with the upper clamp nozzle jackshaft by the jaw bearing pin on the jaw, the upper clamp nozzle upper end is connected with upper clamp nozzle arm front end axle by connecting axle, the position of the inclined to one side front end of upper clamp nozzle arm is pressed on the lower clamp nozzle arm fulcrum, supports back-moving spring between lower clamp nozzle arm and the upper clamp nozzle arm tail end.
Good effect of the present utility model is that it is simple in structure, and is easy to use, can reduce patient's unnecessary harm when exodontia.
Description of drawings
Fig. 1 is structure chart of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1, the small forceps mouth dental forceps of belt supporting frame, it is characterized in that: the front end of nipper plate 1 has the fulcrum 3 of projection, lower clamp nozzle arm 2 inclined to one side front ends have forniciform lower clamp nozzle arm fulcrum 7 and are connected with fulcrum 3 axles by bearing pin, lower clamp nozzle arm 2 front ends are jaw, be connected with upper clamp nozzle 6 jackshafts by jaw bearing pin 5 on the jaw, upper clamp nozzle 6 upper ends are connected with upper clamp nozzle arm 4 front end axles by connecting axle 8, the position of upper clamp nozzle arm 4 inclined to one side front ends is pressed on the lower clamp nozzle arm fulcrum 7, supports back-moving spring 9 between lower clamp nozzle arm 2 and upper clamp nozzle arm 4 tail ends.
During use, hand-held nipper plate 1 stretches in the patient oral cavity, move to the position of the tooth that need to extract, the tooth that the most accurate needs of jaw of upper clamp nozzle 6 and lower clamp nozzle arm 2 are pulled out, press down upper clamp nozzle arm 4 when holding lower clamp nozzle arm 2, upper clamp nozzle arm 4 drives the connecting axle 8 of upper clamp nozzle arm 4 front ends take lower clamp nozzle arm support point 7 as fulcrum, thereby upper clamp nozzle 6 is moved counterclockwise take jaw bearing pin 5 as axle, Distance Shortened clamps the tooth that need to pull out between the jaw of upper clamp nozzle 6 and lower clamp nozzle arm 2, press down simultaneously again lower clamp nozzle arm 2, upper clamp nozzle arm 4, lower clamp nozzle arm 2 fulcrum 3 on the nipper plate 1 is extracted tooth do lever motion as axle.
