Description
Technical field
The present invention relates to a kind of medical appliance equipment being used for the treatment of human bladder's calculus, especially a kind of dual pathways bladder lithotriptoscepe device (or system).
Background technology
Cystolithic therapeutic endoscopy, because wound is little, recover the Main Means having become clinical treatment soon, carries out usually through cystoscope and metal epitheca supporting in addition traditionally.Concretely, this kind of bladder (rubble) mirror forms a kind of single pass bladder lithotriptoscepe (to form a fit connecting device) by a upper metal epitheca with hollow operations hole of 0 ° of lateral telescope nested (adding cover), hollow operations hole between the lateral telescope formed after putting metal epitheca and epitheca is service aisle (i.e. operating walk way), has water intaking valve and outlet valve (controlled valve for infusion liquid turnover), lateral telescope camera lens and lateral telescope optical fiber interface in a termination of this fit connecting device successively.
When utilizing the cystoscope of above-mentioned this fit connecting device to carry out lithotripsy in treatment, after cystoscope sheath metal epitheca inserts bladder, in cystoscopic handle hole, insert Bladder stone optical fiber or pneumatic ballistic lithotripsy striker etc. carry out rubble, irrigation liquid pours operating walk way through water intaking valve, and the mixture of the calculus powder produced in rubble, bladder hemorrhage and infusion liquid is also gone out from inlet/outlet valve through same passage.The method has many defects: 1), the infusion liquid that pours and the blood and slime gone out, calculus mixture of powders is all through the passage inflow and outflow between lateral telescope and metal epitheca, flush efficiency is low, the camera lens visual field very easily causes the operative doctor visual field unclear for blood and slime and calculus mixture of powders pollute, extend operating time, easily accidentally injure bladder.2), exhalant canal is often obstructed, and bladder is in expanded state, and in rubble process, calculus is easily beated, and calculifragous efficiency is low, patient must repeatedly " aiming ", focus on, greatly extend operating time.3) crushed stone that, calculus is larger after smashing not easily is gone out, the lithotomy forceps residual stone of clamp repeatedly must be inserted, increase operation time, even metal epitheca exits bladder thus the urethra damaged outside bladder and prostate repeatedly, increase the weight of hemorrhage, affect the doctor visual field, cause the incidence rate of long-term postoperative urethral stricture to improve.
Separately, also have scholar to utilize transurethral resectoscope sheath, carry out pneumatic ballistic lithotripsy in conjunction with kidney mirror mirror sheath, ureteroscope and bladder side visor, it is advantageous that: (1) resectoscope mirror sheath is roomy, larger calculus fragment is easily gone out, and improves and gets stone efficiency; (2) between resectoscope mirror sheath and operation mirror body, space is large, available flushing liquor continuous irrigation, helps that to ensure that the visual field continues clear; (3) bladder is more hollow, and calculus is fixed in wall of urinary bladder by means of mirror sheath and smashes, and calculifragous efficiency is higher; (4) rubble is got Shi Junke and is undertaken by resectoscope mirror sheath passage, and must repeatedly not change mirror sheath, injury of urethra is little; (5) can the same period treatments B PH, the bladder outlet obstruction (BOO) that causes such as neck of bladder pathological changes.But also there is its shortcoming: (1) single channel lavation, still can affect the visual field during secondary hemorrhage in rubble process; (2) bladder is too hollow, observes calculus difficulty
[14]; (3) calculus must peak at wall of urinary bladder with mirror sheath, and calculus fragment is piled up in mirror sheath passage, easy scratch minute surface; (4) still often must withdraw from sight glass and discharge rubble in mirror sheath passage, increase operating time and risk.
In view of the above, in order to overcome the above-mentioned drawback of conventional medical bladder (rubble) mirror, needing medical expert to design or building the bladder rubble system of short, simple to operation convenience of a kind of rubble time, new ant algorithms that clinical effectiveness is good.
