Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described herein
Execute example be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Refering to Fig. 1,2, one of the present invention medical per os Eustachian tube sacculus dilating catheter is special inserts apparatus, including main
The 1st, pipe pushes pipe 2 and guiding tube 3, and the both sides of supervisor 1 are equipped with grip part 4, and the side pushing pipe 2 arranges grip part 4, pushes pipe
2 pass through supervisor 1 connection guiding tube 3, and guiding tube 3 is arranging spacing preiection 5 with the link position pushing pipe 2, prevents guiding tube 3 quilt
Overdriven.
Guiding tube 3 away from supervisor 1 one end be provided with the swan neck system adapting with Eustachian tube position, swan neck system include with
Guiding tube 3 connects and in first pipe 6 of 120 degree, and other end bending second pipe 7 of the first pipe 6, between the first pipe 6 and the second pipe 7
Angle includes 30 degree, 45 degree or 70 degree of three kinds of angles, and 45 degree and 70 degree are usually used in adult, and 30 degree are usually used in children's, guiding tube 3 He
The plane that plane that first pipe 6 is formed and the first pipe 6 and the second pipe 7 are formed is positioned at different planes, the second pipe 7 away from
One end of first pipe 6 is provided with flare openings, and soft palate part walked around by the first pipe 6, and the first pipe and the second pipe are generally aligned in the same plane A.
As assumed, ingress pipe is positioned at plane B, and if plane B is perpendicular to horizontal plane, between plane A and plane B, acute angle is 60 degree, by
One pipe 6 and the design of the second pipe 7 and its angle, guiding tube 3 enters oral cavity, and soft palate walked around by the first pipe 6, and the second pipe 7 is by pharynx
Sacculus dilating catheter is sent into Eustachian tube by pharyngeal opening of auditory tube, easy to operate.
Supervisor 1 is provided with radial indentation 8, pushes the corresponding radial indentation 8 of pipe 2 and is provided with bootstrap block 9, pushes pipe 2 and be additionally provided with sleeve pipe
10, sleeve pipe 10 and supervisor 1 are threaded, and sleeve pipe 10 is spacing to pushing pipe 2, and bootstrap block 9 moves in radial indentation 8, it is achieved push away
Send the rectilinear movement of pipe 2.
The sidepiece of supervisor 1 is provided with the knob 11 for fixing propelling movement pipe 2 position, after propelling movement pipe 2 moves to correct position,
Turning knob 11, can lock pushing pipe 2.
Push pipe top (i.e. one end away from ingress pipe) internal orifice design screw thread, Eustachian tube foley's tube tail end plastics plastotype
Enlargement designs respective threaded, and after connecting device, plastics plastotype part is fixed on propelling movement pipe top, and during operation, utilization pushes away
Sending the thrust of pipe, sacculus is sent from the second pipe, enters Eustachian tube.
Further, the hinged some support claws in the exit position of the second pipe 7, one end of support claw connects control line, by control
Line processed promotes one end of support claw, can strut pharyngeal opening of auditory tube, facilitates sacculus dilating catheter to enter Eustachian tube.
Its operating principle is:
Under endoscopic observation guides, the parallel Eustachian tube in sacculus portion of sacculus dilating catheter is moved towards direction and inserts Eustachian tube
In, by compression pump water filling dilating sacculus, the bulbs of pressure of sacculus produce squeezing action to cartilaginous part of auditory tube, and continue certain
Time, thus expand the Eustachian tube of stenosis or occlusion.
Operation key step:
Propelling movement pipe 2 is fixed on remote location by optional local anaesthesia or general anesthesia, first fixed knob 11, and will
Sacculus dilating catheter passes through propelling movement pipe 2 and is inserted in guiding tube 3, and now balloon portion is completely hidden in guiding tube 3, by sacculus
Expansion pipe slowly pushes into Eustachian tube along guiding tube 3, should not have any resistance during propelling movement, it is to avoid damage Eustachian tube surface
Mucous membrane, when determine dilating catheter sacculus portion completely into Eustachian tube after, by water injection pressure pump with expand pipe tail end be connected, water filling
Being pressurized to 10atm, maintaining after 2-3 minute pressure release retraction sacculus in guiding tube 3, expansion step finishes.
It finally it is noted that these are only the preferred embodiments of the present invention, is not limited to the present invention, although
