Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially treat a kind of automatic filling formula therapy equipment of cholelithiasis.
Background technology
Gallstone disease is global frequently-occurring disease, very harmful to human health.Along with the trend enhancing of aged tendency of population, the quickening and the growth in the living standard of people's rhythm of life, the sickness rate of gallstone disease constantly raises.Gallstone disease is the general name of cholelithiasis, calculus of intrahepatic duct, extrahepatic bile ducts calculus.According to statistics, cholelithiasis accounts for gallstone disease and always sends out more than 80% of case load.The sickness rate of China adult cholelithiasis is about 10%, middle-aged women even up to 15%.Therefore probing into method efficient, the safe treatment cholelithiasis is very important.
The Therapeutic Method of cholelithiasis has a variety of, mainly is divided into operative therapy and non-operative treatment.Current prevailing treatment means is the excision gallbladder.Open the extensive wound property that abdomen is got the gallbladder operation although its small incision cholecystectomy has reduced tradition, because it still belongs to traumatic means, many patients are reluctant to accept; Laparoscopic cholecystectomy has obviously reduced the health wound; But this scheme needs general anesthesia; Patient's danger such as severe cardiac lung disease, diabetes are very big for suffering from, and the expensive high-end instrument and equipment of these scheme needs, make treatment be difficult to carry out in the general hospital; The most important thing is gallbladder as a part of human body organ, bring infringement can for after the excision people's physiology and psychology, therefore, Most patients more is ready to accept non-operative treatment.
Non-operative treatment mainly comprises oral dissolved stone medicine treatment, ESWL and perfusion lithodialysis method.The most effective in the present oral dissolved stone medicine therapy for taking ursodesoxycholic acid.This medicine toleration is better, is applicable to the cholelithiasis of diameter less than 10mm.Though these therapy oral drugs are convenient, and certain lithodialysis curative effect is arranged, easy for patients to accept, its treatment time is long, and expensive has certain ill effect and toxic reaction, and relapse rate is higher after the drug withdrawal.
ESWL is to utilize liquid electricity, piezoelectricity or magnetoelectric effect to produce shock wave, through medium conduction and focusing, pulverizes a kind of technology of calculi in vivo behind the entering human body.Wherein ultrasonic rubble therapy is to utilize the ultrasound wave of high frequency, high energy, focusing, imports in the body through tissue calculus is produced stress and cavitation, makes the cracked purpose that reaches treatment of calculus.The advantage of this therapy is Noninvasive treatment, simple to operate, painless waiting bitterly for, and shortcoming is very big to the tissue injury around the calculus.If ultransonic intensity is at 0.1W/cm
2When following, do not cause tangible biological effect, if ultrasound intensity is at 0.1W/cm
2Can cause tissue generation functional character and organic variation when above, the part patient biliary colic can occur after implementing this therapy simultaneously.
Perfusion lithodialysis method; Be on master's the basis mainly promptly with the cholesterol type calculus at cholelithiasis; Perfusion a kind of safe and effective cholesterol solvent-methyl tert-butyl ether (MTBE) in gallbladder; Cholelithiasis directly contacts the lithodialysis agent, and drug level is high relatively, thereby reaches the purpose of dissolving calculus fully, rapidly.In addition, in the process of dissolving calculus fast, can not damage gallbladder mucosa.Be applicable to patient such as older, high-risk adhesion of gallbladder that should not operative treatment and hope to keep gallbladder and the patient that selects non-operative treatment.
What mainly adopt in early days is manual directly infusion therapy, by clinical department of internal medicine doctor completion hand-manipulated.Be specially the doctor and through liver puncture conduit inserted patient's gallbladder, use glass syringe perfusion and suction lithodialysis agent such as MTBE through percutaneous, each 5-10ml, branch was extracted out in several minutes, so repeated multiple times.But still there is potential safety hazard in this process, flows into bile duct and intestinal if the MTBE in the gallbladder too much causes it to overflow gallbladder, can be absorbed by the body, and is prone to produce nausea and vomiting, side effect such as haemolysis.Because the gallbladder size there are differences, the calculus amount is different, and the self-constriction property of gallbladder, and these factors all make the people for being difficult to accurately control quantity of solvent, in case solvent is leaked to inside of human body branches such as intestinal, then can cause poisoning, the infringement health.Operation easier is big, efficient is low so manual perfusion lithodialysis method still exists, and the lithodialysis agent is prone to leak and cause easily operator's problems such as fatigue.
CN2875449; A kind of " cholelithiasis dissolving appearance " that is used to treat cholelithiasis disclosed; A kind of computer controlled automatic lithodialysis agent circulation dissolution therapy appearance has been proposed; Owing to adopted the closed loop pressure control model, made the treatment operation of under computer control, accomplishing perfusion dissolving cholelithiasis automatically to have overcome the big shortcoming of poor stability, operation easier that perfusion lithodialysis agent treatment cholelithiasis hand-manipulated exists.But this instrument adopts pressure transducer is placed outside the human gall bladder, transmits pressure application through sealing air and measures IBP power.This pressure testing method precision is low, and instrument reply emergency case response speed is slow, causes instrument safety in operation and poor stability, has treatment hidden danger, so press for a kind of safer, sensitive, therapeutic equipments efficiently.
Summary of the invention
