Abstract
The invention belongs to the operating theater instruments of Urology Surgery posterior urethral stricture.
This resectoscope is that per urethram probe, epitheca are visited core, exsector, remover, guide pin guide, guide pin, light source, suction aspirator tip, cotton swab composition.Several internal urethrotomy cuttves at present both at home and abroad commonly used can only be with the narrow section urethrotomy, can not excise.This resectoscope not only can be with posterior urethral stricture section excision (traumatic, struvite all can), and can utilize transplantation in mucous membrane of urinary bladder and the capable urethra of skin of foreskin, prevents back urethra restenosis.
Description
The invention belongs to the operating theater instruments (A61b, 17/32) of Urology Surgery posterior urethral stricture
By literature search, also be not specifically designed to the resectoscope of treatment posterior urethral stricture both at home and abroad.The internal urethrotomy cutter that several replacements are only arranged in this technical field.The internal urethrotomy cutter divides blindness (no sight glass) and has two big classes of sight glass.Incision knife is the described internal urethrotomy cutter of Otis in 1878 in the external commonly used blindness, and this cutter, costs an arm and a leg, can not generally apply complex structure.Domestic internal urethrotomy cutter commonly used is that Maisonneuve type cutter, this cutter insert the bladder palpus by the seal wire guiding, if seal wire is difficult to insert bladder, operation just can't be carried out.Another kind is the Riba cutter, utilizes the high frequency electric cutting, and the possibility of damage normal structure is arranged, and adopts very few.A kind of inner cutter that has sight glass of Sachse in 1973 design, though effect is better than incision knife in blindly, operating difficulties is sometimes because of bubble and hemorrhagely make that the visual field is unclear just can not to undergo surgery.The major defect of these internal urethrotomy cuttves is in a word: the narrow section urethrotomy can not can only be excised the narrow section urethra; Easily normal urethra of damage and rectum in the operating process, in agglutination the back urethra have restenosis may, and complex structure, operating difficulties, damage easily, cost an arm and a leg, be difficult for promoting.
The present invention is in view of above-mentioned several internal urethrotomy cuttves, can only be with the narrow section urethrotomy, and unresectable shortcoming designs and produces out.
Main points of the present invention are: the posterior urethral stricture resectoscope is made up of anterior urethra probe, resectoscope epitheca spy core, scar excision cutter, remover, guide pin guide, guide pin, light source, suction aspirator tip, cotton swab.During operation the resectoscope epitheca is inserted anterior urethra, adopt direct-view to insert guide pin down, the scar excision cutter is excision posterior urethral stricture part under the guide pin guiding, can avoid the damage of normal urethra and rectum like this, if remaining scar tissue and the fragment of leaving over of organizing are arranged in the urethra, available remover is removed, when back urethra is inaccessible, available guide pin guide is introduced bladder with guide pin, by the inaccessible section of above-mentioned operating procedure excision back urethra, in order to prevent back urethra restenosis, also can utilize mucous membrane of urinary bladder, anaplasty in the capable urethra of skin of foreskin.
The present invention proves that through clinical trial the posterior urethral stricture resectoscope is simple to operate, safe and reliable, the patients after surgery unobstructed micturition, and no sexual dysfunction is painful little, recovers fast, and the hospital stays is short, eutherapeutic advantage.
The present invention not only can treat traumatic posterior urethral stricture, can also treat struvite posterior urethral stricture.
Cutter head of Fig. 1 (1-1) scar excision cutter is made up of two perpendicular blades and cutter hub, is characterized in excising sharp keen, but can not take out the excision thing voluntarily sometimes.
No. two cutter heads of Fig. 1 (1-2) scar excision cutter are made up of two perpendicular blades and two oblique blades and cutter hub.Be characterized in and scar tissue can be excised, and the excision thing can be taken out voluntarily, but can not fixation guide pin.
No. three cutter heads of Fig. 1 (1-3) scar excision cutter are made up of two perpendicular blades, guide pin fixing hole of two oblique blades and cutter hub, are characterized in: not only can and the excision thing can be taken out voluntarily the scar tissue excision, well fixation guide pin.Three kinds of cutter heads all can be used, and wherein No. three cutter heads are ideal.
Fig. 2 remover is made up of remover head (1), bar (2), handle (3), and head is a Cylinder chamber, there are two and half garden shape blades at its middle part, and a storage chamber and blunt shape dilator head are removed the residue tissue, the stored tissue fragment takes out the effect of removing thing and expansion back urethra voluntarily.
Fig. 3 guide pin guide is made up of guide head (1), body (2), bar (3), handle (4).For the inaccessible patient of back urethra, it can be inserted internal urethral orifice, push handle, the guide pin guiding tube can pass inaccessible section urethra automatically, guide pin inserted in the guiding tube, release handle, guide pin just is inhaled into bladder automatically again by operating procedure, the inaccessible section of excision back urethra.
