Description
Technical field
The invention belongs to medical instruments fields, more particularly, to stricture dilation guiding device.
Background technique
As clinical common medical instrument, catheter is after being per urethram placed in human body by urine from bladder drainage to body
Outside, main function is accurate recording urine volume, convenient for drainage and flushing etc., is played a significant role in clinic.
Catheter material mainly has silica gel, rubber, EVA, PVC etc., and head end and tube body are partially soft.But some patients are because of urine
Situations such as road is narrow, hyperplasia of prostate, canceration, neck of urinary bladder hardening causes urethra internal resistance bigger than normal, greatly increases and sets pipe difficulty.It is existing
There is clinical catheterization usually after disinfection orificium urethrae externum and surrounding tissue on the other hand orificium urethrae externum is fixed, another hand is direct or uses
Tweezers etc. hold catheter, are inserted into from urethral orifice, when facing resistance bending and narrow situation, then need more firmly to be placed in, to trouble
Person brings huge pain, causes the damage of mucous membrane of urethra, causes the destruction of urologic structure, increases the risk of urinary tract infection.
It is had the following problems during the catheter merging of existing clinic: when catheter head top marches at ankylurethria
When need to increase external force propulsion, shear action can occur for apical head and stenosis urethra, even by narrow urethra, in urethra
Film also suffers from serious contusion and creates conditions for microorganism infection, urethral catheterization tube outer surface coating lubricating oil etc., narrow in reply urethra
It produces little effect when narrow.
It is clinically placed in catheter and replacement urinary catheter is sometimes extremely difficult, and easily cause violence insertion urinary catheter when institute band
The secondary urethral injury come, such as via, bleeding, perforation, and then aggravated the severity of urethral disease, affected urethra
Healing even results in the urethral injury of complexity and narrow, has seriously affected the life quality of patient.Therefore for above-mentioned trouble
Person, in order to be avoided the occurrence of when being placed in catheter via generally requiring to be placed in catheter under the guidance of seal wire.And it existing leads
Urinary catheter majority is front end sealing end, and the tube body of open rearward end, side is open and communicates with urethral catheterization lumen.This catheter is placed in seal wire
When, seal wire is open by the side of catheter by lumen and is drawn, therefore cannot be guaranteed that the position of catheter and seal wire is parallel to each other,
It causes guidance difficult, is placed in urethral catheterization tube failure.
The prior art mostly places seal wire inside catheter, and catheter is placed in urethra by intensity higher seal wire.
Summary of the invention
The stricture dilation guiding device that the object of the present invention is to provide a kind of structures simply, catheter merging is facilitated to operate.
The technical scheme is that
Stricture dilation guiding device, the stricture dilation guide body including tubulose, stricture dilation guide body front end are set
There is guide portion, guide portion rear end is equipped with air bag, and the stricture dilation guide body side wall of inside air bag is equipped with through-hole, narrow expansion
The rear end for opening guide body is equipped with elastic sack body, and elastic sack body and stricture dilation guide body form an inside and be full of gas
The sealing space of body or liquid.
Stricture dilation guiding device of the present invention is in use, be inserted into the urine passageway of catheter, stricture dilation guiding device sheet
The opening that the guide portion and air bag of body front end pass through catheter front end is located at outside catheter front end.In use, stricture dilation draws
Seal wire can be played the role of by leading device, work as ankylurethria, catheter cannot by when, stricture dilation guiding device is travelled forward one
Segment distance, then squeezes elastic sack body, by elastic sack body gas or liquid be pressed into air bag by through-hole, gas
Capsule is propped up, and urethra side wall is strutted, catheter moves on.Then elastic sack body is unclamped, gas or liquid in frontal air bag
It flows back into elastic sack body, then repetitive operation, until catheter front end enters inside bladder, fixation balloon is filled up, will be narrow
Narrow expanding pilot device is withdrawn from.The generation of urethra side wall can be cut to avoid catheter when placing catheter using stricture dilation guiding device
Shear force avoids causing to damage to urethra, highly-safe, and patient's no pain in placement process, and compliance is good.
The front end of the air bag is equipped with air bag retainer plate, and air bag retainer plate inner sidewall is outer with stricture dilation guide body
Side wall is fixedly linked, and the front end face of air bag is recurvate curved surface.
The rear end face of air bag is the plane with stricture dilation guide body axis perpendicular.
The rear end face of air bag is recurvate curved surface.
Air bag rear end face is recurvate curved surface, when air bag struts, distance that the front end of catheter travels forward compared with
Greatly, the time of catheter merging operation shortens, and reduces patient's pain.
The rear end of air bag is equipped with air bag retainer plate, the lateral wall of air bag retainer plate inner sidewall and stricture dilation guide body
It is fixedly linked, the rear end face of air bag is the prone curved surface symmetrical with front end face.
The inner sidewall of air bag is equipped with the reinforcement protrusion of annular, reinforces protrusion and mutually hangs down with stricture dilation guide body axis
Directly.
Reinforce protrusion can to avoid air bag full of when irregular deformation occur, avoid the air bag of the side of inner catheter compared with
Small close to urethra side wall, and the air bag of the other side is larger, far from urethra side wall, so as to avoid catheter front end and urethra side
Shearing force is generated between wall.
The guide portion front end face is paraboloid or ellipsoid.
Guide portion can introduce wherein by more narrow urethra, and by stricture dilation guiding device.Paraboloid or
Ellipsoid is more smooth, when entering in urethra, will not generate shearing force to urethra side wall, reduce damage when being intubated to urethra
Wound.
Elastic sack body front end is additionally provided with elastic bellows, the rear end of elastic bellows be in contact with elastic sack body outer surface or
Connection, stricture dilation guide body rear end pass through elastic bellows and are connected with elastic sack body.
Spring substitution can be used in elastic bellows.
Elastic sack body is equipped with switch valve.
Can by switch valve into elastic sack body make-up gas or liquid.
The advantages and positive effects of the present invention are: due to the adoption of the above technical scheme, catheter merging is safer
It is convenient, and the intensity of catheter can be further reduced, increase the flexibility of catheter, reduces patient's pain;With knot
The advantages that structure is simple, and processing cost is low, highly-safe, the present invention is in addition to outer for ankylurethria expansion, it may also be used for esophagus, directly
Intestines etc. other need to be inserted into the position of pipeline.
