Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of teeth nerve needles.
Background technology
The dental explorer using in Hospitals at Present dental treatment chamber mostly is the instrument of metal material, and can repeatedly sterilize, reuse, if but sterilization is not thorough, and patient uses the various oral diseases of rear easy cross infection, brings healthy hidden danger to patient.In order to overcome this problem, also someone has developed disposable teeth nerve needles.There is certain problem in current disposable teeth nerve needles: 1. the wasting of resources, financial burden weight; 2. function singleness, does not have other assosting effects; Even if 3. also have other miscellaneous functions, also be the union joint of an each fixing a kind of shape specification in handle two ends, dentist in use selects different union joints as required, need constantly the union joint in upset hands, not only cannot ensure health, easily carry pathogenic bacteria, the easy cross infection of patient, and the handle of metal is inconvenient to grip, be easy to landing.
Summary of the invention
It is a kind of easy to use, simple to operate that the purpose of this utility model is to provide, and has the teeth nerve needles of several functions, safety and sanitation.
This utility model is achieved in that
Teeth nerve needles of the present utility model, comprise in turn handle, handle bar and probe, on probe, be provided with V-type connecting rod and probe, on probe, be provided with scale, handle bar is connected by V-type connecting rod with probe, handle bar is connected with the V-type connecting rod on probe with handle respectively, and probe is Rhizoma Sparganii shape probe.
The present invention is Rhizoma Sparganii shape by probe design, makes it can either investigation depth, can clear up again gingiva; And during do not need probe to take out, can carry out continued operation, not only convenient, easy to operate, save time, also ensured patient's oral hygiene, prevented because of need to clean gingiva change cleaning head cause antibacterial infect, stopped the hidden danger of cross infection.
Teeth nerve needles of the present utility model, the end of probe is level and smooth face.
Probe end face is set to level and smooth face instead of tip-shape setting, is in order to survey accurately, exerts oneself excessively cause most advanced and sophisticated damage to patient oral cavity and survey inaccurate while preventing from surveying.
Teeth nerve needles of the present utility model, V-type connecting rod and probe angulation θ, 105 °≤θ≤130 °.
In this angular range, medical personnel are easy to operate, survey accurately.
Teeth nerve needles of the present utility model, θ=120 °.
When the θ=120 °, grip more comfortable, medical personnel's more convenient operation, it is more accurate to survey.
Teeth nerve needles of the present utility model, handle bar is flexibly connected with probe.
Handle bar is flexibly connected with probe, convenient to the replacing of popping one's head in, and both can avoid bringing to patient because repeatedly sterilizing the hidden danger of cross infection, the wasting of resources that can avoid disposable probe to bring again.
Teeth nerve needles of the present utility model, handle bar and one end that the V-type connecting rod on probe is connected, be provided with groove, and groove inner surface is provided with female thread; V-type connecting rod and one end that handle bar is connected, be provided with plush copper, and plush copper outer surface is provided with the external screw thread matching with the female thread of groove; Groove is threaded with plush copper.
Handle bar is threaded with probe, and the replacing that both can conveniently pop one's head in can make again handle bar and probe stable connection, facilitates medical personnel's operation, ensures the accuracy of surveying.
Teeth nerve needles of the present utility model, is provided with anti-slip veins on handle.
The setting of anti-slip veins, can prevent that medical personnel from using time, handle skids, and causes to survey and is forbidden, and even unexpected injury is caused in patient oral cavity and gingiva.
The beneficial effects of the utility model are, teeth nerve needles of the present utility model, easy to use, simple to operate, time saving and energy saving, survey accurately, both can avoid bringing to patient because repeatedly sterilizing the hidden danger of cross infection, the wasting of resources that can avoid disposable probe to bring again.
