Abstract
The utility model relates to a calculus removed catheter which comprises an outer tube body (1), a compliance balloon (3) arranged at the front end of the outer tube body, a developing point (5), a connecting piece (6), a two-way valve (8) and a guide wire (7). The calculus removed catheter is characterized in that the outer tube body (1) is divided into two parts, the rear part of the outer tube body (1) is a first-class diameter and is connected with the two-way valve (8) through the connecting piece (6), and the front part of the outer tube body (1) is a section of front end tube body (2) with the bore diminishing gradually. The front end tube body (2) is arranged at the position of 20 centimeters to 100 centimeters behind the top end of the remote end of the whole outer tube body.
Description
Technical field
This utility model relates to a kind of medical diagnosis and treatment apparatus, refers in particular to a kind ofly to get the stone conduit for biliary tract and pancreatic stone operation usefulness.
Background technology
Biliary tract in the digestive organs of human body and pancreas are because a variety of causes generation calculus, narrow and the pathological changes such as block, if do not diagnose for a long time and treat, abdominal pain gently then occurs, lose weight, the symptom such as jaundice, and then initiation inflammation, develop at last cancer of biliary duct, cancer of pancreas, serious threat human life safety.At present, endoscopic technique has replaced traditional abdominal operation of opening owing to advantages such as it does not open abdomen, the little risk of wound is little, recovery is fast, few intercurrent diseases, has become the Main Means that diseases of pancreaticobiliary duct is diagnosed, carried out Minimally Invasive Surgery.
During operation endoscope is entered behind the target location by the digestion tract, then seal wire and other medical apparatus and instruments (such as angiography catheter, high frequency incision knife etc.) are passed endoscope path way, again seal wire is positioned in the biliary tract; Then other apparatus (such as stone extraction basket, dilating sacculus is got the stone conduit, drainage tube, support etc.) is got stone by predetermined guiding of inserting seal wire in the bile duct, and the operations such as expansion tract or drain arrive and recover biliary tract and the unobstructed purpose of pancreas.
Increasingly mature along with endoscopic technique is with the supporting balloon expandable apparatus of endoscopic technique with get the stone technology and also constantly developed.Cholelithiasis mainly is distributed in the common bile duct at present, the part calculus also is distributed in the stones in intrahepatic bile duct of far-end simultaneously, generally can remove by getting the stone conduit for the calculus in the common bile duct, at present we generally to use what get the stone conduit all are the conduits that wait gauge structure, this isometrical pipe diameter is thick and compliance is relatively poor, generally can only enter into more straight and the larger common bile duct tract of diameter; But be difficult to enter into the thin crooked stones in intrahepatic bile duct of far-end, thereby the calculus in the stones in intrahepatic bile duct is difficult to remove by the stone conduit of getting of this kind structure.
The utility model content
The purpose of this utility model: be to provide a kind of have good propelling movement performance and pass through performance get the stone conduit.
This stone conduit of getting is by outer tube body 1, the compliant balloon 3 of being located at the outer tube body front end, development point 5, connector 6, two-way valve 8 and seal wire 7, it is characterized in that: described outer tube body 1 is by being divided into two parts: its rear portion is one isometrical and be connected with two-way valve 8 through connector 6, and its front is the front end body 2 that one section bore diminishes gradually.
Described front end body 2 is located at the 20-100cm position after the whole outer tube body distal tip.
According to a kind of characteristics of getting the stone conduit of above Technical Design be: the section compliance is different before and after the conduit, conduit leading portion compliance is good, the 20-100cm place is the gradual change structure that diminishes gradually, and the rear end of conduit size is thicker, rigidity is better, the section compliance is different before and after the conduit, and the conduit leading portion gradually transition structure that diminishes provides enough compliances and passing through property, and the thick harder structure of rear end of conduit can provide enough good propelling movement performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: a 1-outer tube body 2-leading portion body 3-compliant balloon 4-mouth spray 5-development point 6-connection tube 7-seal wire 8-two-way valve 9-balloon expandable mouth 10-fluid-through port 11-venthole.
The specific embodiment
As shown in Figure 1 get the stone conduit by outer tube body 1, be located at the outer tube body front end compliant balloon 3, point 5, connector 6, two-way valve 8 and seal wire 7 develop, it is characterized in that: described outer tube body 1 is by being divided into two parts: its rear portion is one isometrical and be connected with two-way valve 8 through connector 6, and its front is the front end body 2 that one section bore diminishes gradually.
Described front end body 2 is located at the 20-100cm position after the whole outer tube body distal tip.
In actual applications, compliant balloon can be used polyurethane elastomer, silica gel, and nylon elastomer, natural emulsion, other macromolecular elastomer materials are made.
The development available radiopaque metal of point and alloy, such as rustless steel, gold, silver, the platinum material is made.
The outer tube body nylon-type, polyurethane, silica gel, polrvinyl chloride, polyethylene, the medical macromolecular materials such as polypropylene are made.
Connector, fluid-through port, balloon expandable mouth, seal wire mouth all can be made of macromolecular material.
Get the stone operating procedure as follows:
Get the stone conduit and enter into bile duct along seal wire, because conduit leading portion diameter is less gentle far away, continue to be fed forward conduit, conduit even can enter into the stones in intrahepatic bile duct of far-end, the development point 5 of catheter proximal end can be determined the advance position of arrival of conduit; Mouth spray 10 on connector injects contrast solution, contrast solution from link into an integrated entity mouth spray 4 ejection of end of front end body 2 of outer tube body, can determine the structure of bile duct and the position of calculus by contrast solution, continue delivery conduit until conduit is crossed the position of calculus; Then in two-way valve 8, inject air, air out makes inflation along outer tube body 1 inner chamber from the venthole 11 that is positioned at compliant balloon 3 positions, and rotation two-way valve upper knob makes sacculus keep inflated condition, at last with catheter pullback, calculus is pulled out from bile duct, finishes and gets the stone step.If once fully calculus is not all taken out, can repeat above step, repeat to get the stone action.
Claims (2)
1. get the stone conduit by outer tube body (1), the compliant balloon (3) of being located at the outer tube body front end, development point (5), connector (6), two-way valve (8) and seal wire (7) for one kind, it is characterized in that: described outer tube body (1) is by being divided into two parts: its rear portion is one isometrical and be connected with two-way valve (8) through connector (6), and its front is the front end body (2) that one section bore diminishes gradually.
2. a kind of stone conduit of getting as claimed in claim 1, it is characterized in that: described front end body (2) is located at the 20-100cm position after the whole outer tube body distal tip.
