Description
Technical field
A kind of propeller is the utility model is related to, specifically a kind of clinic tympanostomy tube that is used for puts pushing away for pipe operation
Into device.
Background technology
Chronic nonsuppurative otitis media is a kind of common disease, frequently-occurring disease, is more common in children.Influence to hearing is tighter
Weight, so that influencing the intellectual development and study of children.Its cause of disease is mostly obstruction of eustachian tube, causes hydrotympanum.Hydrotympanum by
The diseases such as catarrhal otitis media, secretory otitis media, aero-otitis and otitic barotrauma cause.The drainage of hydrotympanum
It is one of important measures for treating nonsuppurative otitis media, common method is tympanostomy tube tube placing operation.Put Guan Kejing external auditory meatus,
Eardrum is by snorkel incarceration at eardrum incision (upper and lower of tympanostomy tube respectively outside eardrum in).Snorkel, which can play, to be drawn
Stream drum indoor liquid and the effect of ventilation.The structure of tympanostomy tube is mostly I-shaped snorkel at present, it is with snorkel sheet
Body, lower edges are the annular edge being relatively large in diameter, it is therefore an objective to stablize snorkel, prevent it from falling in tympanum or deviating from tympanum
Outside.I-shaped snorkel also has some special shapes, inserts and takes out easy to it, and sharp blade is equipped with as lower edge is anterior,
Draw ring is equipped with easy to take out easy to eardrum notch, or top edges, or inclined side etc..It is first that eardrum, which cuts tube placing operation operating procedure,
In eardrum upper cut, then using apparatus (wheat pincers) by snorkel through external auditory meatus, by tympanostomy tube lower edge sharp edges
Portion is inserted in eardrum notch, and second step is inserted at tympanostomy tube lower edge rear portion in eardrum notch using prong.But at present
Put pipe step for second step, have no special I-shaped tympanostomy tube and promote utensil, due to the needle point of prong it is relatively thin thus by
Doctor puts pipe for propulsion, but prong and tympanostomy tube contact area are small, easily makes to put pipe dislocation or abjection, it is difficult to once
Insert, add the operation difficulty of micrurgy, extend operating time, procedure efficiency reduces.
How hot spot that above-mentioned the problems of the prior art be those skilled in the art research is solved.
The content of the invention
The technical problem to be solved by the utility model is to provide a kind of clinic tympanostomy tube that is used for put pipe operation
Propeller.
To achieve these goals, the utility model adopts the following technical solution：
A kind of tympanostomy tube propeller, wherein, the propeller includes handle, pushing ram and puts tube head；The handle
It is fixedly connected with pushing ram one end, angle is 130~150 degree therebetween；The pushing ram other end connects with putting tube head and fixing
Connect, angle is 130~150 degree therebetween；The tube head of putting is arc plate, its central angle is 120~180 degree, a diameter of 1.5
~1.8mm.
Wherein more preferably, the height for putting tube head is 0.4~0.5mm, and thickness is 0.01~0.02mm.
Wherein more preferably, the length of the handle is 8~12mm.
Wherein more preferably, the handle diameters are 4~6mm.
Wherein more preferably, the length of the pushing ram is 6~8mm.
Wherein more preferably, a diameter of 0.3~0.5mm of the pushing ram.
Wherein more preferably, the handle outer surface is equipped with anti-skid structure.
The utility model is suitable for I-shaped tympanostomy tube, and other snorkels with neck.
In the utility model, handle and pushing ram and pushing ram and the angle put between tube head put pipe behaviour with tympanostomy tube
It coincide as angle, doctor is easy to operation, and does not block the visual field.The selection of the two length coincide with tube placing operation operating position, makes
It is more convenient that doctor is affectedly bashful operation.Support snorkel body can be stablized by putting the design of tube head arc plate, add propeller and ventilation
The size of the contact area of pipe, its central angle and diameter can effectively encircle tympanostomy tube and avoid snorkel from misplacing, and utilize
The utility model carries out tympanostomy tube and puts pipe operation, can once insert, time saving and energy saving, reduces operating difficulty, shortens
Operating time, improves procedure efficiency.The utility model has good potential applicability in clinical practice.

Embodiment
As shown in Fig. 1,2 and 3, the utility model discloses a kind of tympanostomy tube propeller, it includes handle 1, promotes
Bar 2 and put tube head 3；Handle 1 is fixedly connected with 2 one end of pushing ram, and included angle A is preferable in 130~150 degree therebetween, is suitable
The angle of doctor's hand-held is closed, the best angle that included angle A uses in the present embodiment is 135 degree.
The length of handle 1 is preferable in 8~12mm, too short to be not easy to be affectedly bashful, and long crank influences operation precision, this
Embodiment uses optimum length 10mm.Handle diameters are preferred in 4~6mm, and the present embodiment uses optimum diameter 5mm, are grasped through experiment
Confirm, it is optimal that flexible precision is affectedly bashful and is operated to the diameter and length value.2 outer surface of handle is equipped with anti-skid structure, this reality
Apply example and use grid knurling structure, anti-skidding effect when being affectedly bashful with increase.
2 other end of pushing ram is fixedly connected with putting tube head 3, and it in the range of 130~150 degree is preferable that included angle B, which is, therebetween
Work angle, included angle B is using 135 degree of best angles in the present embodiment.The length of pushing ram 2 is very crucial, its length
It is preferable in 6~8mm, it is long it is too short can all influence operate precision, be verified by experiments, the present embodiment use optimum length be
6.5mm, operation precision are optimal.In 0.3~0.5mm preferably, the present embodiment uses optimal values 0.4mm to 3 diameter of pushing ram.
The excessive propeller preponderance of diameter, is likely to result in the change of position of centre of gravity, and can block the visual field, and then influences operation.
It is an arc plate to put tube head 3, and the preferred range of its central angle is 120~180 degree, if central angle is less than 120 degree,
Arc length is too short to occur the small unstable situation of carrying of contact area, if central angle is more than 180 degree, arc length is long, contact surface
Product is excessive, is not easy to recall after blocking the visual field and operation, in the range of the utility model provides conveniently.The present embodiment uses
120 degree of optimally central angle degree, i.e., 1/3rd circles, the arc-like sheet of this central angle suitably carry snorkel, convenient operation.Put pipe
First 3 diameter is set according to snorkel body outside diameter, and snorkel body outside diameter is 1.45mm, therefore puts the preferable of 3 diameter of tube head
Scope is 1.5~1.8mm, and diameter is difficult to encircle snorkel less than 1.5mm inserts, and makes to insert difficulty, can make support more than 1.8mm
Loosely, 3 diameter of tube head is put in the present embodiment and uses 1.5mm, is optimum diameter value in above range.The height for putting tube head 3 is
0.4~0.5mm, is about snorkel body high 1/3~1/4, such as less than 0.4mm, puts tube head 3 and becomes with snorkel contact area
It is small, influence to operate；Put tube head and be highly more than 0.5mm, can show slightly heavy, can also influence the visual field and operation.The thickness for putting tube head 3 is
0.01~0.02mm is preferable, and thickness, which crosses conference, influences operation ease.
As shown in figure 4, when the utility model is used, first cut eardrum, then by apparatus by tympanostomy tube 4
Part is inserted in eardrum notch, and last doctor will be put tube head 3 and encircled the snorkel body of tympanostomy tube 4 using the utility model
Outside inserts at snorkel lower edge rear portion in tympanum, single stepping, precisely in place.
