Description
Technical field
It the utility model is related to technical field of medical instruments, and in particular to a kind of eardrum cuts tube placing device.
Background technology
On medicinal, the secretory otitis media or glue ear of recurrent exerbation are run into, it usually needs using tube adapter for drum membrane
Art, the operation mainly include incised tympanic membrane and toward ventilation two steps of drainage tube are put into otch, and the general use of incised tympanic membrane is cut
Knife is completed, and is put into ventilation drainage tube and is then typically completed using tube placing device, and existing tube placing device includes core bar, outer tube and led to
Gas drainage tube, core bar are located in outer tube, and ventilation draining-tube cover is on the leading section of core bar, during operation, by core bar with cutting
Mouth alignment, the rear end of outer tube is then pressed by thumb, the front end of outer tube is pushed ventilation drainage tube and get into otch
It is interior, so set not only operation laborious, and deficient in stability in operating process, once thumb loosens, partly squeeze into
Ventilation drainage tube be also easy to fall back, so as to cause repeatedly to extrude repeatedly, increase patient suffering.In addition, existing cutting knife
It is separate with tube placing device, so also result in the defects of operation is inconvenient, efficiency is low.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides drum that is a kind of easy to operation and can effectively reducing mortality
Film cuts tube placing device.
To achieve the above object, the utility model provides a kind of eardrum and cuts tube placing device, include core bar, outer tube and
Ventilation drainage tube, core bar are located in outer tube, and ventilation draining-tube cover is on the leading section of core bar, the front end face of the core bar
On integrally formed with cutting knife, be provided with grab handle in the rearward end of the core bar, one section be additionally provided with the rear end of the core bar
Thread segment, and be spirally connected on the thread segment and be equiped with pushnut, it is provided with pressure between pushnut and the outer tube rear end
Contracting spring, is additionally provided with positioner between outer tube and core bar.
The beneficial effects of the utility model are：Said structure is used, firstly, since the utility model is integral by the cutting knife
It is molded on the front end face of core bar, therefore medical worker need not change instrument after incised tympanic membrane, just can be immediately placed into ventilation and draw
Flow tube, it is more convenient to operate, more efficient.Secondly, grab handle is set in the rearward end of the core bar, medical worker can be made
Grab handle can be gripped when being operated and carries out stable operation, so as to substantially reduce the mortality of operation.Finally, operate
When, due to being provided with positioner between outer tube and core bar, therefore before positioner does not release, outer tube will not move
It is dynamic, so that medical worker first passes through the incised tympanic membrane operation that cutting knife completes early stage, after the completion of, positioner is released, it is described outer
Sleeve pipe will promote ventilation drainage tube reach in the presence of compression spring, ventilation drainage tube is first pressed on the otch of eardrum,
Then ventilation drainage tube is slowly pushed and got into otch by turn pushnut by people, because pushnut is and core bar
Screw thread coordinate, even if therefore human hand loosens in extrusion process, also can effectively prevent from retreating, so that whole process is more
Smoothly carry out, effectively reduce mortality.
The utility model can be further arranged to described positioner and include radial direction latch, fixed support, reset bullet
Spring, fixed support are fixed on the outer surface of outer tube, and radial direction latch is described successively radially across fixed support and outer tube
The locating slot being inserted radially into for radial direction latch is correspondingly provided with core bar, described back-moving spring is sleeved on radial direction latch, radially
Radial lobes are additionally provided with latch, the both ends of back-moving spring abut with radial lobes and support bracket fastened inwall respectively, and force
Radial direction latch is inserted radially into the locating slot of core bar.
Using said structure, before positioner does not release, the radial direction latch is inserted in the locating slot of core bar, so that
Obtain and positioning fixation is formed between outer tube and core bar, avoid outer tube from moving；Hereafter, people, which only need to radially outward pull, radially inserts
Pin, makes radial direction latch overcome the elastic force of back-moving spring to be separated with the locating slot of core bar, and positioner is just released from, overall structure letter
It is single, it is easy to operate.
The utility model may further be provided is positioned close to outer tube rear end for described positioner.So set
Put, it is easy to operation.
It is in mushroom that the utility model, which may further be provided as the front end of the ventilation drainage tube, in this way, being easy to
People will ventilate in drainage tube push-in otch；The rear end of the ventilation drainage tube is provided with Non-return ring, in this way, can effectively prevent
The ventilation drainage tube being put into skids off.
The utility model may further be provided to be set for described cutting knife in crosswise.So set and be not only convenient for cutting
Cut, and be easy to otch to position, so as to contribute to follow-up pipe of putting to operate.
The utility model may further be provided is provided with finger embedded groove for described grab handle.In this way, it can make
People grip more securely, avoid the occurrence of skidding.
