Description
One, technical field
The present invention relates to a kind of operating theater instruments of removing calculus, especially a kind of 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, a kind of carry magnet gas control dislodger is provided, characteristics such as make it have flexibly movable and good operation effect, simplicity of design, control be easy, safe and reliable.
The objective of the invention is to adopt following scheme to realize: a kind of carry magnet gas control dislodger; It comprises operating grip, conduit and stone taking device, is characterized in: it also comprises 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; There is the interior pipe of a trachea and resin to be communicated with in the handle bar of said operating grip, on the handle bar, also has notch, have bleeding point to be connected in the notch with trachea; Said stone taking device by fixed block, holder and be connected fixed block and holder between the cover net constitute; The cover net is made up of some thin hollow pitch tubes around the even double-walled construction of arranging of conduit; Pipe, holder form a gas circuit in said trachea, the resin; Use inflator pump hollow pitch tube to be inflated or venting, realize the folding of cover net, reach the purpose of getting stone through this gas circuit; On the outer wall of thin hollow pitch tube inboard, countless small magnets are housed, all thin hollow pitch tubes can be shunk before unaerated draw close.
Above-mentioned hollow pitch tube one end is fixed on the fixed block periphery; The other end is fixed on the holder periphery; And have pore on the inwall in the hollow pitch tube outside; And hollow pitch tube and fixed block are fixed through fixed cover, and this pore and fixed cover make hollow pitch tube outwardly-bent easily after inflation, promptly overlap net and open; Holder is fixed on the resin inner tube mouth, and the aperture corresponding with hollow pitch tube arranged on holder, and pipe is communicated with hollow pitch tube by these apertures in the resin; Through above-mentioned gas circuit hollow pitch tube is filled, exits and control the opening and closing of cover net; When it was inflated, cover net middle part was outwards opened and can be got stone, when it is exitted; Inwardly draw at cover net middle part, convenient turnover bile duct.
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 demonstration armarium such as the computer of outside.
Above-mentioned light source can be the LED lamp, and it penetrates light from the vacuum cup card, illuminate 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: 1) in getting the stone operation, use this carry magnet gas control dislodger can reduce the liver injury bile duct, alleviated patient's misery, made things convenient for doctor's operation; 2) this carry magnet gas control dislodger cover calculus is firm, gets the cubic meter of stone just, has improved the work efficiency of surgical staff widely; 3) the cover net utilizes Magnet to draw in, makes its volume little, conveniently stretches into biliary tract.
