Abstract

The utility model relates to an automatic pressure irrigator for fibre biliary tract endoscope, which belongs to the field of the endoscope in the medical instrument. The utility model is composed of a pressure pump, a control stand, a rubber pipe, a liquid charging bottle, etc. The utility model is characterized in a motor, a pressing rod and a speed regulator. Through pressing the liquid in the rubber pipe by a press wheel and regulating the rotation speed of the motor, the washing pressure can reach 176-294 kpa, accordingly the utility model can be used in the fibre checking calculus removal in the operation and after operation. The problems that the pressure is not enough dripped and washed by an infusion bottle of the past fibre biliary tract endoscope, small calculus and biliary mud can be dashed out, and the incarcerated calculus is loosed and the larger calculus is dashed from the far biliary tract to the near biliary tract to facilitate extraction. The utility model is a new generation auxiliary device of the fiber biliary tract endoscope used for replacing the irrigation of the infusion bottle.

Description

Automatic pressure irrigator for fibre biliary tract endoscope

This device belongs to medical apparatus and instruments endoscope field, checks and get the new accessory device of stone for fiber endoscopy (abbreviation fibro-endocholedoscopy) in operation, and back fiber endoscopy inspection and get stone also can be used for performing the operation.This device is based on fiber endoscopy, by do the biliary tract flushing with the liquid of suitable pressure, make stones in intrahepatic bile duct obtain suitable expansion, except plaing a part better the flushing biliary tract clear visual field is convenient to check, also can directly microlith and gallbladder mud be gone out, also can make calculous obstruction loosening and be flushed to the near-end bile duct from the far-end bile duct, be convenient to take out than maximum size.Can further improve the effect that stone is got in the fibro-endocholedoscopy inspection, shorten and get stone time and number of times, improve calculus and once get clean rate.If can with development recently through fibro-endocholedoscopy calculi breaking device (plasma stock wave rubble and electrohydraulic lithotripsy etc.) common application, it is better to get the stone effect, is auxiliary equipment that must obligato a new generation in the fibro-endocholedoscopy clinical practice.

Fiber endoscopy is at China's dependence on import always, the fibro-endocholedoscopy standard cover of import also comprises adnexaes such as lithotomy net, biopsy forceps, cold light source except that the fibro-endocholedoscopy main body, biliary tract flushing part is just used common infusion bottle, at present fibro-endocholedoscopy still exists and checks that lithotomy method and stone taking device are perfect inadequately, definite inadequately effectively wait not enough.The postoperative fibro-endocholedoscopy checks that lithotomy method is: get one by one only with lithotomy net under photopic vision after T pipe sinus tract insertion fibro-endocholedoscopy is spied on near-end and far-end bile duct successively, seen calculus clearly, need connect the common transfusion bottle and the normal saline that instils in the art.At present, undergo surgery both at home and abroad in the fibro-endocholedoscopy inspection method of getting stone be to indiscriminately imitate the method (seeing accompanying drawing 1) that stone is got in the inspection of postoperative fibro-endocholedoscopy.This device designer fibro-endocholedoscopy inspection in carrying out art is got and is recognized in the practice of stone that this indiscriminately imitating is different suitable, it is not enough to make the bath pressure of flusher with the common transfusion bottle when fibro-endocholedoscopy is checked after surgery, make that the stones in intrahepatic bile duct expansion is not enough, be unfavorable for checking and get stone.The design person improves using the fibro-endocholedoscopy lithotomy method in the calculus of intrahepatic duct operation in the period of 1987～1989, mainly be to change the infusion bottle flusher into the pressure flush device, homemade pressure flush device connects two plastic tubes by the unidirectional continuous pressure injector of a 30ml and forms, outlet pipe connects the fibro-endocholedoscopy water inlet, suction hose is put into the basin that fills with normal saline, assist to take out repeatedly to push away the irrigation with syringe biliary tract by instrument nurse on the platform, until getting clean calculus, flushing pressure is regulated by the speed that pushes away syringe, and flushing pressure can reach 13.2～22.1mmHg or 1.76～2.94Kpa.The result is that the calculus of improving one's methods is once got clean rate and brought up to 82.33% by 52.63% of former method, gets the stone time to shorten to 47 minutes in 63 minutes by the need of former method.The more former method of stamping press is big 2～3 times although improve one's methods, the same complication such as biliary tract infection ［ see practical surgical magazine 1991.11(11 for details) .579 ］ that all do not increase with former method.This device is exactly a deficiency of checking lithotomy method and apparatus at fibro-endocholedoscopy in the art, is applied at the manual pressure flusher design on the basis of clinical success.

The purpose of utility model is the deficiency at fibro-endocholedoscopy lithotomy method and apparatus, and the fibro-endocholedoscopy that more is applicable to clinical practice auxiliary equipment is provided, and replaces the common transfusion bottle instillation flushing of in the past using, and further improves the effect that stone is got in fine choledochoscope inspection.

The purpose of this utility model is achieved in that this device is by force (forcing) pump (comprising motor and pressure ram), control station (comprising tachoscope, Pressure gauge, speed governing button and speed regulator, clockwise or reverse button, switch etc.), trestle table and liquid holding bottle five most of form (seeing accompanying drawing 3).It is characterized in that pressure ram (the pressure ram structure is seen Fig. 4), form by spring, pinch roller, wheel pressing shaft, pinch roller bearing, the compensating roller Luo bolt of pinch roller, dwang plate, pressure ram is fixed on the motor rotation axis, speed regulator is connected with motor, requirement is under the situation of using internal diameter as the sebific duct of 0.6cm, two kinds of specifications of 0.8cm, make flushing pressure reach 1.76～2.94Kpa by liquid and adjusting motor speed in the pinch roller rotation extruding sebific duct, when using, this force (forcing) pump need not sterilize, only need the sterilization sebific duct to get final product, very convenient, meet the medical aseptic requirement.After the sebific duct of will sterilizing during use was put into the pinch roller of force (forcing) pump, sebific duct was connected with liquid holding bottle with the fibro-endocholedoscopy water inlet respectively, energized, motor rotating band dynamic pressure wheel, liquid in the sebific duct is driven to fibro-endocholedoscopy, regulate the controllable rotation speed pressing pressure, reach the effect of automatic pressure flush.If motor is reversed, just play sucking action (seeing accompanying drawing 5).

This utility model is because only need add this device on original equipment, this apparatus structure is simple to operation, realizes this purpose easily.

This device with manually press flusher relatively, have the labor intensity and the workload that alleviate the nurse, guarantee that flushing pressure is constant accurately and regulated at will, be more conducive to check and get advantage such as stone.In art or the fine gallbladder inspection of postoperative get and use this device and the former application infusion bottle former method of washing that instils in the stone and compare, make biliary tract flushing automatization, and have the function of pressure flush and attraction concurrently, can further improve the result that stone is got in the fibro-endocholedoscopy inspection, shorten and get stone time and number of times, improve calculus and once get clean rate.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 for the fibro-endocholedoscopy of present both at home and abroad widespread usage in art and the postoperative inspection instil with the common transfusion bottle when getting stone and make the sketch map (being called for short former method flusher) that biliary tract washes.Wherein fibro-endocholedoscopy (1), infusion bottle (2), tube for transfusion (3);
