Description

The gas control dislodger

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 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 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; Described conduit is made of pipe in resin outer tube and the resin; Described switch and socket are used to control light source and photographic head work, and photographic head is connected with socket, switch by the lead that passes the resin outer tube with light source; There is a trachea to be communicated with in the handle bar of described operating grip, on the handle bar, also has notch, have bleeding point to be connected in the notch with trachea with pipe in the resin; Described stone taking device by fixed block, holder and be connected fixed block and holder between the cover net constitute, the cover net is made of some thin hollow pitch tubes around the even double-walled construction of arranging of conduit, on the outer wall of thin hollow pitch tube inboard, have countless pores, also open countless pores on the inwall in the outside, make it produce negative pressure and make hollow pitch tube outwardly-bent from same direction; Pipe, holder form a gas circuit in described trachea, the resin, use inflator pump to pass through this gas circuit to hollow pitch tube inflation or venting, realize the folding of cover net, reach the purpose of getting stone.

Above-mentioned hollow pitch tube one end is fixed on the fixed block periphery, and the other end is fixed on the holder periphery, and hollow pitch tube all is to have this side of pore on the wall interior, to realize outwardly-bent purpose; Holder is fixed on the resin inner tube mouth, the aperture corresponding with hollow pitch tube arranged on holder, pipe is communicated with hollow pitch tube by these apertures in the resin, by 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 other end of anode power cord is connected with negative power supply jack on the socket, the cathode power supply jack of socket is connected by lead with a contact of switch, 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, by the trend of mathematical model comparison software precognition 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 gas control dislodger can reduce the liver injury bile duct, alleviated patient's misery, made things convenient for doctor's operation; 2) this gas control dislodger cover calculus is firm, gets the cubic meter of stone just, has improved the work efficiency of surgical staff widely.
