Abstract
Aural curet.In hospital's otology, for meeting the requirement of extensive patients, alleviate patient's misery, cure the disease and ask for help, often adopt aural curet.This utility model forms and comprises: aural curet body, the top of described body is vertebra type bar (1), one end of described vertebra type bar has a little spoon (2), described little spoon is 25 ° with tapered rod axis angle (3), the bottom of described body is that the other end of vertebra type bar has threaded rod, described threaded rod is connected with annular knurl connecting rod (4), one end of described annular knurl connecting rod has screwed hole, on described annular knurl connecting rod, there is a planar slot (5), described plane towards direction and described little spoon spoon face towards direction consistent, described plane is convenient to be installed with in the threaded rod described in hand-held operation a branch of optical fibers (6), described optical fibers port distribution is on described little spoon, described little spoon is upper with micro-photographic head (7).This utility model is used for foreign body in ear operation scraping tract.
Description
technical field:
this utility model relates to a kind of aural curet.
background technology:
with sharp-pointed instrument, pick one's ears, tympanum can be stabbed because of carelessness to even perforation, serious meeting causes deafness.With hard thing or earpick, accidentally can encounter tympanum, the undue force that picks one's ears, the most easily causes external auditory meatus damage to infect and forms furuncle and phyma, causes ear's pain, and severe patient can cause auditory dysesthesia.Harm is a lot, gently causes auditory meatus inflammation, heavy can make auditory dysesthesia even lose.Anything is stretched into the danger that auditory meatus has the perforation of ear drum of making.
summary of the invention:
the purpose of this utility model is to provide a kind of aural curet.
above-mentioned object realizes by following technical scheme:
a kind of aural curet, its composition comprises: aural curet, the top of described body is vertebra type bar, one end of described vertebra type bar has a little spoon, described little spoon and 25 ° of the axis angles of tapered rod, the bottom of described body is that the other end of vertebra type bar has threaded rod, described threaded rod is connected with annular knurl connecting rod, one end of described annular knurl connecting rod has screwed hole, on described annular knurl connecting rod, there is a planar slot, described plane towards direction and described little spoon spoon face towards direction consistent, described plane is parallel with the axis of little spoon place tapered rod, described plane is convenient to hold conveniently, in described threaded rod, be installed with a branch of optical fibers, described optical fibers port distribution is on described little spoon, described little spoon is upper with micro-photographic head
write the content of claims herein
the beneficial effects of the utility model:
1, this utility model adopts unique design, and aural curet capitiform is answered even thickness, small and exquisite.Aural curet (sharp) head should sharply can stretch into different angles, different directions in earhole and draw and dig.
, each connecting portion of this utility model aural curet is connected firmly, the screw thread involvement of vertebra type bar and annular knurl connecting rod connects and removes and installs conveniently, and solid and reliable.
, be installed with a branch of optical fibers in described threaded rod, described optical fibers port distribution is on described little spoon, described little spoon is upper with micro-photographic head, has thoroughly changed traditional draw ear to draw or blindly draw caused unfavorable result, and operation process can have been transmitted to preservation by data wire.This utility model aural curet is through heat treatment, and its head hardness is that 20Cr13,2Cr13Mo are 377-478HV0.2, and 30Cr13 is 478-560HV0.2.
, this utility model aural curet the numerical value of outer surface roughness (except handle flower) parameter Ra should be not more than: have bright 0.4 μ m, without bright 0.8 μ m.
, this utility model aural curet should have good decay resistance.
, this utility model aural curet profile should smooth, rounding, without cutting edge of a knife or a sword rib, burr.Handle flower is answered complete display, without hypodontia, rotten tooth.
, this utility model aural curet planar slot should be smooth, thumb is controlled plane and is handled very skillfully, and holds conveniently.
accompanying drawing explanation:
accompanying drawing 1 is the structural representation of utility model.
accompanying drawing 2 is partial enlarged drawings of putting A place of accompanying drawing 1.
the specific embodiment:
embodiment 1:
a kind of aural curet, its composition comprises: aural curet, the top of described body is vertebra type bar 1, one end of described vertebra type bar has a little spoon, described little spoon and 25 ° of tapered rod axis angles, the bottom of described body is that the other end of vertebra type bar has threaded rod, described threaded rod is connected with annular knurl connecting rod 2, one end of described annular knurl connecting rod has screwed hole, on described annular knurl connecting rod, there is a planar slot, described plane towards direction and described little spoon spoon face towards direction consistent.Aural curet is used for foreign body in ear operation scraping tract.
in described threaded rod, be installed with a branch of optical fibers 6, described optical fibers port distribution is on described little spoon, and described little spoon is upper with micro-photographic head 7.During work, optical fibers is by outside light to entering in ear, and doctor can be in the situation that having illumination, and the situation spreading out of by photographic head accurately, is clearly carried out cerumen and removed operation, avoids the auditory meatus damage that blindly operation brings.
embodiment 2:
according to the aural curet described in embodiment 1, aural curet should adopt 20Cr13, the 30Cr13 material in 2Cr13Mo or GB/T1220, stipulated to make.Through heat treatment, its head hardness is that 20Cr13,2Cr13Mo are 377-478HV0.2, and 30Cr13 is 478-560HV0.2
