Description
Technical field
This utility model relates to a kind of auxiliary device of organ surgery, relates in particular to a kind of medical perfusion and attracts platform, and it is applied to the armarium in medical domain Urology Surgery PCN art and ureteroscopy or other professional intracavity operations of medical domain.
Background technology
Percutaneous nephrolithotomy is the main Therapeutic Method of upper lithangiuria.At present most widely used is mainly that standard channel (20～24Fr) and micro-fistulation (14～18Fr) PCN are got two kinds of art formulas of stone (Yuhico MP. KO R. The current status of percutaneous nephrolithotomy in the management of kidney stones Minerva Urol Nefrol. [J] 2008; 60 (3): 159-175.).Micro-fistulation percutaneous nephrolithotomy is the effective ways for the treatment of renal calculus; also be the development trend that PCN is got stone; micro-its passage of fistulation PCN is little, wound is little; coordinate High-power holmium laser with mini rubble; its lithotrity effect is good, go out insufficiency of blood is its advantage (Ye LH; Chen YL, Xu DS. et al. Clinical comparative study of five minimally invasive surgeries for upper urinary tract calculi[J]. Zhonghua Yi Xue Za Zhi.2010; 90 (4): 228-230).But clear cubic meter of stone formula is mainly got rubble by high pressure pouring and pincers; Infection in operation rubble discharges antibacterial, pyrogen is absorbed into blood circulation with high pressure pouring liquid; cause in art or postoperative fever, bacteremia, septic shock (Li LY even; Gao X; Yang M, et al .Does a smaller tract in percutaneous nephrolithotomy contribute to less invasiveness A prospective comparative study[J]. Urology.2010; 75 (1): 56-61.); Standard channel percutaneous nephrolithotomy coordinates the clear stone system of ultrasonic trajectory rubble can immediately remove calculus; reduce or avoid pincers to get rubble and High-Pressure Water is gone out rubble; effectively reduce renal pelvis internal pressure; reduce rubble and got the absorption of toxin and pyrogen in stone process; heating, bacteremic incidence rate are reduced; reduce intravenous extravasation (Song L; Chen Z; Liu T, et al. The application of a patented system to minimally invasive percutaneous nephrolithotomy[J] .J Endourol. 2011 Aug; 25 (8): 1281-1286); But standard channel percutaneous nephrolithotomy still can not accurately regulate and monitor renal pelvis internal pressure, can not eliminate renal pelvis inner high voltage and water completely and pour into the risk of bringing.And be more renal pelvis internal pressure in art by what urological surgeon paid close attention to, all medical perfusion equipments only have injection pressure and two parameter settings of flow at present both at home and abroad, patient manually regulates and controls by clinical experience, have larger randomly and uncertain, and surgical experience is less or begin to learn operator and be difficult for grasping.Occur that injection pressure is too high, thereby cause intracavity liquid to backflow and exosmose, when particularly calculus merges urinary tract infection, the severe complications such as urine source property pyemia easily occur, severe patient causes patient death.Chinese scholars has been noticed the very big hazardness that in percutaneous nephrolithotomy, renal pelvis inner high voltage causes, but so far without well monitoring and solution.Given this, be necessary to improve prior art.
