Abstract
The utility model relates to a catheter with two snake-head-shaped ends, which belongs to the technical field of medical appliances. The catheter is characterized in that the catheter is divided into two head ends which share a cavity with a main catheter body, wherein each separate catheter has a semi-circular cross section, the two head ends are combined together to form a circle before being released and are restricted through an outer sleeve; and the two head ends are pigtail-shaped after being released. The catheter has the beneficial effects that the deficiencies of the prior art are overcome, and the two head ends can be respectively and accurately selected to enter the bile duct at one side and the duodenum after entering the catheter; if the two head ends of the catheter have different length, the longer head end is selected to enter the duodenum so as to greatly improve the efficiency and the success ratio of searching; simultaneously, the operation time is greatly shortened; puncturing for twice or positioning two drainage tubes is not necessary, thus alleviating the wound and the pain of a patient; the structure is simple, the operation is convenient, time saving and safe, the catheter is suitable for a section of any length where pathological change occurs, and the application range is broad.
Description
Technical field
This utility model belongs to the medical equipment technical field.
Background technology
The interventional therapy of obstruction of bile duct is the hot issue of operation in the present age.Existing modus operandi is: percutaneous is sent into the superslide seal wire after the success of liver approach bile duct puncture, and what need interior external drainage passes through narrow section with seal wire, sends into trocar sheath, withdraws from seal wire, sends into to add stiff guide wire, sends into drainage tube along adding stiff guide wire.Simple external drainage, drainage tube place narrow near-end, and the drainage tube far-end places in the duodenum during interior external drainage, and near-end places in the bile duct of expansion.If block and involve left and right sides common hepatic duct simultaneously, drainage tube can only be placed big branch, or the capable left and right sides of midaxillary line, under the xiphoid-process and the right side common hepatic duct drainage that punctures simultaneously.
Existing conduit is generally many side openings tubulature, external diameter 6F～8F (3F=1mm), length 30～40cm.(1 inch=2.54cm) seal wire of diameter, along this seal wire, conduit advances in bile duct can to pass through one 0.014～0.038 inch in the conduit cavity.Catheter main body is that polyethylene or nylon 12 and 304 stainless steel silks weave by 1: 1 moment of torsion, and catheter block is a polycarbonate, and head end black part tungstenic is convenient to have an X-rayed down observation.Seal wire enters from the catheter block uropore, passes from the stomidium of conduit.The conduit head end often has a nylon yarn to lead to tail end by inner chamber, is fixed by locking device again, makes the head end form be fixed as the pigtail shape, and prevents that conduit from deviating from.
But existing conduit can't once solve to block and involve left and right sides common hepatic duct problem simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of double end snakehead end conduit, and be characterized in: conduit is the double end end, each split conduit cross section semicircular in shape.This utility model has overcome the deficiencies in the prior art, can once solve to involve simultaneously blocking of left and right sides common hepatic duct.
Main technical schemes of the present utility model is: a kind of double end end conduit is characterized in that: conduit is divided into two head ends, is total to the chamber with catheter main body, each split conduit cross section semicircular in shape, and the double end end does not lump together and is circle before discharging, and the trocar sheath constraint is arranged outward.Discharging back double end end is the pigtail shape.
Described catheter main body is divided into the semicircle conduit of side opening more than two when reaching certain length be good.
Two catheter lengths that separate can be isometric can be not isometric, the cross section semicircular in shape.The cross section that two conduits that separate lump together is tapered to good for circular with total body diameter.
Described conduit external diameter 8F～10F is good.
2 stomidium semicirculars in shape of described conduit.
The described conduit side opening that separates is rounded.
It is good that described conduit stomidium peripheral part conduit contains roentgenopaque metal, so that so that perspective is observed the location down.
Described roentgenopaque metal is gold, platinum or tungsten and alloy thereof.
Guide-tube structure such as accompanying drawing.
Good effect of the present utility model is: overcome the deficiencies in the prior art, after conduit enters, can accurately two head ends be selected into a side bile duct and a duodenum respectively, as being not isometric head end conduit, a long end is selected into duodenum, can improves the efficient and the success rate of searching greatly; Significantly reduced operating time simultaneously; Needn't puncture for 2 times or insert 2 drainage tubes, reduce patient's wound and misery; It is simple in structure, easy to operate, when joint, safety, and pathological changes segment length is short all to be suitable for applied range.
Be described further below in conjunction with embodiment and accompanying drawing, but not as to qualification of the present utility model.
Description of drawings
Accompanying drawing is the structural representation of this utility model double end snakehead end conduit.
In the accompanying drawing, the implication of each label is: 1, conduit stomidium, 2, the conduit side opening, 3, the saturating X ray part of conduit, 4, the semicircle duct portion that separates, 5, trocar sheath, 6, catheter main body, 7, the catheter block uropore.
The specific embodiment
Referring to accompanying drawing, this double end snakehead end conduit comprises catheter main body 6 and conduit split 4 and split conduit head end 3, it is characterized in that: divide body canal 4 to continue mutually with catheter main body 6, split conduit head end 3 is the pigtail shape.Divide body canal 4 all to be constrained in the trocar sheath 5 before discharging, be a circular pipe shape in appearance.Discharge back double end end 3 and separate tortuous separately one-tenth pigtail shape.Stomidium 1 semicircular in shape.Duct portion tungstenic or gold, platinum or alloy around the stomidium 1 (can same prior art).Conduit semi-circular portion length can be different, correspondingly produce multiple series of products, take the circumstances into consideration to select for use according to the difference of pathological changes.The operation of conduit is same as prior art substantially.The long 30-40cm of conduit is good.Conduit, seal wire can be used prior art.
During use, along seal wire double end snakehead end conduit is sent in the bile duct, and make the trocar sheath head end near region of obstruction, then with two superslide seal wires in the catheter main body, make wherein that a seal wire is selected into a side bile duct, another root is selected into duodenum, return then and remove trocar sheath, two conduit head ends that separate are sent into a side bile duct and a duodenum along seal wire respectively,, a long end is selected into the duodenum side as being not isometric head end conduit.The nylon yarn of pulling back makes head end be pigtail shape and fixing.
This utility model catheter main body is divided into two semicircle conduits, has overcome the deficiencies in the prior art, and suitable and one-time puncture is inserted two cover drainage catheters, and 2 positions of need not puncturing also need not be inserted 2 cover drainage tubes respectively.Select the not isometric conduit of different length and head end for use, can improve the efficient and the success rate of searching greatly; Significantly reduced operating time simultaneously; Patient's wound and misery have been reduced; Surgical wound is convenient to management; It is simple in structure, easy to operate, when joint, safety, and pathological changes segment length is short all to be suitable for applied range.
