Description
One, technical field
The present invention relates to a kind of operating theater instruments of removing calculus, especially a kind of multi-functional dislodger that is used for gallbladder, bile duct.
Two, background technology
At present, detect at Minimally Invasive Surgery treatment gallbladder, calculus of bile duct and to get in the stone operation, lack special-purpose gallbladder, bile duct dislodger always.In actual operation, the clinician mainly relies on stone extraction basket to get stone, but stone extraction basket easy slippage when extracting calculus, especially for less calculus; When running into bigger calculus, stone extraction basket can't stretch and entangle calculus, and particularly when the calculus incarceration was in gallbladder or bile duct, stone extraction basket can't be crossed calculus, will cause getting the stone overlong time like this, even failure.After adopting stone extraction basket to get the stone failure, just use traditional abdominal apparatus to carry out gallbladder, calculus of bile duct is removed, or utilize expensive rock crushing plant to carry out re-using stone extraction basket behind the rubble and get stone, perhaps direct transfer abdominal.In above-mentioned operation practice, often, not only increased patient's misery because of getting the stone transfer abdominal of failing, and again just the patient paid expensive medical expense.
Three, summary of the invention
The objective of the invention is to solve that above-mentioned existing to get the stone operation not enough, provide a kind of and have illumination, shooting, rubble, get the dislodger of multiple function such as stone, have movable flexibly, characteristics such as easy, safe and reliable, the good operation effect of control.
The objective of the invention is to adopt following scheme to realize: a kind of multi-functional dislodger; It comprises operating grip, conduit and stone taking device; Be characterized in: it also comprises the plasma rubble cutter that is connected with stone taking device in the conduit, and supervising device of being made up of photographic head, lead, switch, socket and the illuminator of being made up of light source, lead, switch, socket; Said conduit is made up of pipe in resin outer tube and the resin; Said switch and socket are used to control light source and photographic head work, and photographic head is connected with socket, switch through the lead that passes the resin outer tube with light source; Have shifting chute on the handle bar of said operating grip, mobile control loop is housed on the handle bar can move forward and backward along shifting chute, and drive plasma rubble cutter also moves forward and backward; Said stone taking device by slide block, holder and be connected slide block and holder between the cover net constitute; The cover net is made up of several some seizing wires of evenly arranging around plasma rubble cutter; And realize the folding of cover net through moving forward and backward of said plasma rubble cutter, reach and get the stone purpose.
There is finger ring at handle bar rear portion at operating grip, and fixed muffle is equipped with in the front portion, and above-mentioned conduit inserts and is fixed in the fixed muffle, and above-mentioned switch and socket are contained on the fixed muffle, make things convenient for lead to pass the resin outer tube and are connected with switch with socket.Fix at peripheral reinforcing sleeve in addition of catheter tail and fixed muffle.
Seizing wire one end of above-mentioned cover net is fixed on the slide block periphery, and the other end is fixed on the holder periphery, and holder is fixed on the resin inner tube mouth, has 2 apertures to adorn light source and photographic head respectively at the holder end face, at the holder middle part aperture is arranged; Above-mentioned plasma rubble cutter front end passes pipe back in the resin and is got in the cover net by the aperture at holder middle part, and passes slide block and fix with it.Moving forward and backward of plasma rubble cutter drives slide block and moves forward and backward like this, and moving forward of slide block promptly inwardly draws cover net middle part in away from holder, and the moving backward of slide block promptly relies on holder outwards opens cover net middle part.
Move the control loop front on the handle bar of aforesaid operations handle plasma electrode is housed; Above-mentioned plasma rubble cutter pass plasma electrode and with its electric connection, plasma electrode connects plasma generator, plasma electrode can impel plasma rubble cutter to produce plasma, reaches the purpose of rubble.
Above-mentioned mobile control loop is contained in the operating grip periphery; And can move forward and backward along shifting chute, above-mentioned plasma rubble cutter rear end is inserted the handle bar of operating grip and is fixed with mobile control loop, and the drive plasma rubble cutter that moves forward and backward that moves control loop also moves forward and backward; And then the pulling slide block relies on or away from holder; Make cover net middle part open or draw in, overlap net like this and just can realize opening and closing movement, reach the purpose of getting stone.
Above-mentioned resin outer tube is spiraled by three pitch tubes and forms; Pass through positive and negative electrode power line and holding wire in it respectively; Positive and negative electrode power line one end is connected with the positive and negative electrode of light source and photographic head respectively; The negative power supply jack is connected on the other end of anode power cord and the socket, and the cathode power supply jack of socket is connected through lead with a contact of switch, and the other end of cathode power supply line is connected with another contact of switch; Positive and negative electrode power line, socket, switch just form the loop like this, realize the power supply control to light source and photographic head; Holding wire one end is connected with the signal end of photographic head, and the other end is connected with the signal output socket of socket, and the signal output socket connects the display device such as the computer of outside.
Above-mentioned light source can be the LED lamp, and it is online that it transports light to cover, illuminates biliary tract, makes the doctor can clearly see calculus, and it is accurate, errorless to guarantee to take a sample; Above-mentioned photographic head outputs to display device such as computer with situation in the biliary tract, through the trend of mathematical model comparison software prevision Abnormal Development, and set up trend intelligent analysis system, set up the data base.
The present invention adopts the beneficial effect of such scheme to be: when 1) using this multi-functional dislodger, when its stone taking device gets into biliary tract when inner, can clearly see calculus through illuminator; Can accurately judge, improve the accuracy rate and the convenience of dislodger greatly, and be difficult for hurting other organs; Alleviate the patient suffering, reach the effect of operation well, and illumination is stable; Acomia thermal phenomenon, safe and reliable; 2) carry out knapper's work through plasma rubble cutter getting Shi Qianxian, convenient cover net is got calculus, especially maximum size; 3) this multi-functional dislodger cover calculus is firm, gets the cubic meter of stone just, has improved the work efficiency of surgical staff widely; 4) set up mathematical model through the shooting analysis; The mathematical model of being gathered can note abnormalities through the front and back comparison software automatically; And when noting abnormalities, report to the police, can draw a pathological changes trend development direction simultaneously, so just can prevent, in time take in case of necessity the treatment measure in advance.Trend through mathematical model comparison software prevision Abnormal Development simultaneously, and set up trend intelligent analysis system, set up the data base, abundant clinical database can draw a lot of useful unusual experiences, and our doctor's medical skill level is improved constantly.
