Abstract
An endoscopic surgical puncture head comprises a bracket, a frame arranged on the bracket, and a transparent protective cover arranged at the front end of the frame and with an internal hollow cavity. The frame serves as a supporter. During the operation, the transparent protective cover can push human tissues to form an observation field, and remove the barriers of endoscopic objective lens to keep a clear visual field. The utility model has the advantages of easy disassembly, disposable use, and no cross infection. After applied to the endoscope, the surgical puncture head is helpful for the operator to observe clearly the conditions inside the human body even though there are no natural canals or hollow cavities in human body. The clinical trials prove that the surgical puncture head has reasonable design, simple structure, good performance and no risk of causing cross infections, can be used with the visualized puncturing apparatus for intravaginal slingplasty for the treatment of stress incontinence, and can also be used with other visualized puncturing endoscopes.
Description
Technical field
This utility model belongs to surgical instruments or method and technology field, is specifically related to be used for the like instrument of organ pipe in the body.
Background technology
The modal urinary incontinence of women comprises the urgent mixed urinary incontinence of stress incontinence, urge incontinence and pressure.Wherein common with stress incontinence, be meant the patient in cough, sneeze, when abdominal pressure such as laugh, stand up increases suddenly, urine is out of hand and flow out in spite of oneself.Especially giving birth among child's the women had the difficult labour history or suffered from uterine prolapse, bladder and urethra bulging person.After the old menopause of women, owing to lack estrogen, cause the urethra attenuation, the resistance by urethra is reduced, urinary incontinence more more to be seen.
Recognize in instructing according to adult's urinary incontinence clinical practice of being delivered by health policy and research institution recently: the number of U.S.'s urinary incontinence is 1,000 3 hundred ten thousand, 85% to be the women, and the estimation age is that 30～59 years old women about 1/4 once lived through urinary incontinence.Urinary incontinence can betide children's and adolescence, but the old people is in the majority.Live in its urinary incontinence incidence rate of old people in family or the long term care facilities greater than 50%; Found that according to the sampling survey in Chongqing and two places, Beijing in 2002 of national urinary incontinence centre of prevention and cure: 18～28 years old incidence rate of women is 9.6%, 29～39 years old incidence rate is 19.2%, 40～49 years old incidence rate is 34.1%, 50～59 years old incidence rate is 46.1%, 60～69 years old incidence rate is 53.8%, more than 70 years old is 68.2%, and the male is rare.Urinary incontinence has been listed in one of the world's five big diseases.
The therapeutic modality of stress incontinence has multiple, and the curative effect of its operative treatment is ideal, and the suspender art in the operative treatment is an effective method the most, is considered to treat the classical art formula of female stress urinary incontinence always, and its cure rate is 85%～90%.Present operation process is to pass patient's lower abdomen thigh film by a crooked puncture instrument, draw a suspender belt, urethra is suspended in midair, make when abdominal pressure increases suddenly, suspender belt also tightens up in response to increasing of abdominal pressure simultaneously to improve urethra, increase urethral resistance, thereby avoided overflowing of urine, reach therapeutic purposes.The piercing process of this operation is not visible, exist and wear out bladder, the risk of blood vessel etc., therefore the clinical experience to the doctor requires high, the hospital that can carry out also often will enter bladder by cystoscope and carry out indirect observation, have only this moment when puncturing head and run into just can realize whether cause danger when lateral wall of urinary bladder produces pressure to bladder near bladder, but can not realize the dislocation of other direction, can not prevent unexpected generation effectively, be limited to above-mentioned difficult point, the hospital and the doctor that can carry out this operation at present are few, the hospital that is limited to some medical conditions and facility advanced person can carry out more, can not satisfy present so many treatment demand.
The applicant of this utility model patent has designed the vagina sting operation to treat pressure urinary incontinence visual puncturing device, this operative treatment with perforator when undergoing surgery, operator should be observed the real-time condition that perforator punctures into the inside of human body tissue, endoscope itself can not realize the function that punctures, need be at puncturing head of its header arrangement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, simple in structure, operation puncturing head of endoscope that result of use is good for the vagina sting operation to treat pressure urinary incontinence visual puncturing device.
The technical scheme that solves the problems of the technologies described above employing is: support is provided with skeleton, and the front end of skeleton is provided with the inner transparent shield of cavity that is.
Skeleton of the present utility model was made of crossing connection of a main framing and a fibula frame.
The leading section of main framing of the present utility model and fibula frame is that R is the circular arc of 6～8mm, open rearward end, the surface is the rectangle stainless steel metal frame structure of black, the angle of two medial surface of main framing 3 and fibula frame 2 front ends is 60 °～150 °, the front end inner shafts of main framing is to being processed with width and the identical direct through groove of fibula frame thickness, two inboards, rear end are processed with projection, two outsides are processed with projection, the front end outboard shafts of fibula frame is to being processed with the width direct through groove identical with main framing thickness, front end two outsides are processed with or do not have curved hook, and two inboards, rear end of fibula frame are ledge structure, two outsides are processed with two projections.
The thickness of main framing of the present utility model and fibula frame is 0.1～0.5mm.
Support of the present utility model is a tubular, is processed with step in the support inboard, and two lateral surface of support are the cylinder curved surface, in addition two sides are the plane, axially is processed with the width straight trough identical with main framing thickness one at the cylinder curved surface of two lateral surface of support.
Transparent shield of the present utility model is: the rear end is that diameter cylinder, the front end identical with fibula frame width with main framing are that radius is that ball-crown body, the middle part of 0.5～4mm is to be that rotating shaft is the annular solid of 6～8mm circular arc rotation with radius with main framing and fibula frame symmetrical center line, the front end of this annular solid and ball-crown body outer surface kissing connect, the outer surface kissing of rear end and cylinder connects, and are processed with into water through hole and water outlet through hole on this transparent shield.
The thickness of transparent shield of the present utility model is 0.2～0.8mm.
This utility model adopts cross one another skeleton is set on support, at the skeleton front end transparent protective shield is set, and skeleton plays a supportive role; transparency protected covering on when undergoing surgery treatment, the extruding tissue forms field of view; prevent that the person tissue from stopping objective of endoscope, makes the visual field unaffected.Cross infection has been avoided in this utility model easy accessibility, disposable use.After being installed in this utility model in the endoscope, when undergoing surgery, can make endoscope under the situation that no nature duct or cavity on the human body form, operator can clearly observe the situation that this utility model enters the inside of human body position.It has reasonable in design, simple in structure, advantages such as result of use is good, no cross infection to this utility model through the clinical trial proof, can on the vagina sting operation to treat pressure urinary incontinence visual puncturing device, use, also can on other visual operation puncture endoscope, use.
