Abstract
The utility model discloses a kind of bile duct puncture external member, include puncture needle component, seal wire, sheath pipe assembly, conduit and special seal wire; The puncture needle that described puncture needle component includes hollow tubular and the nook closing member mated with puncture needle internal diameter, and the rear end of puncture needle is removably connected with active joint; The external diameter of described seal wire mates with the internal diameter of puncture needle; The length of described sheath pipe assembly be less than puncture needle remove active joint after length.After lancet puncture puts in place, active joint can being pulled down, sheath pipe assembly is introduced along puncture needle, after sheath pipe assembly enters common hepatic duct, withdraw from seal wire and nook closing member, injecting contrast agent by importing sheath, understand the overall out of shape and narrow location of common hepatic duct.Then special conduit, seal wire is introduced along stay pipe, by fitting through narrow section or entering duodenum.Give subsequently and placement inside-and-outside drainage or support, complete operation technique.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of puncturing kit for bile duct puncture.
Background technology
The bile duct puncture external member of current use mainly contains the product of COOK and Megtron company, but all there is certain defect, and need ceaselessly to change puncturing kit, in Renewal process of being everlasting, occur that seal wire skids off or seal wire, puncture needle strand cable cause puncture failure.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, conveniently can get involved the disposable bile duct puncture external member structure completing seal wire, conduit switching motion of doctor after providing a kind of puncture to put in place.
For realizing the object of this utility model, being achieved by the following technical solutions: a kind of bile duct puncture external member, including puncture needle component, seal wire, sheath pipe assembly, conduit and special seal wire; The puncture needle that described puncture needle component includes hollow tubular and the nook closing member mated with puncture needle internal diameter, and the rear end of puncture needle is removably connected with active joint; Described sheath pipe assembly includes stay pipe and imports sheath, and the external diameter of stay pipe mates with the internal diameter importing sheath, and the internal diameter of stay pipe mates with the external diameter of puncture needle; The external diameter of described seal wire mates with the internal diameter of puncture needle; The length of described sheath pipe assembly be less than puncture needle remove active joint after length; The front end of described conduit is tapered, and the length of conduit is 40cm, and the length of described special seal wire is 80-85cm; Described seal wire is platinum seal wire, and the head end of seal wire is soft, and it is harder that tail end compares head end; The length that described puncture needle is removed after active joint is 20-25cm, and the length of sheath pipe assembly is 13-17cm.
Compared with prior art, the beneficial effects of the utility model are: because puncture needle rear end is removably connected with active joint, after puncture puts in place, active joint can be pulled down, sheath pipe assembly is introduced along puncture needle, after sheath pipe assembly enters common hepatic duct, withdraws from seal wire and nook closing member, injecting contrast agent by importing sheath, understanding the overall out of shape and narrow location of common hepatic duct.Then special conduit, seal wire is introduced along stay pipe, by fitting through narrow section or entering duodenum.Give subsequently and placement inside-and-outside drainage or support, complete operation technique.The tapered conduit in described front end conveniently enters narrow section, and catheter design becomes size can just by described stay pipe, obviously like this facilitates operation technique.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1, puncture needle component; 11, puncture needle; 111, active joint; 12, nook closing member; 2, seal wire; 3, sheath pipe assembly; 31, stay pipe; 32, sheath is imported; 4, conduit; 5, special seal wire.
Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to Fig. 1, a kind of bile duct puncture external member described in the present embodiment, includes puncture needle component 1, seal wire 2 and sheath pipe assembly 3; The puncture needle 11 that described puncture needle component includes hollow tubular and the nook closing member 12 mated with puncture needle internal diameter, and the rear end of puncture needle has been threaded connection active joint 111; Described sheath pipe assembly includes stay pipe 31 and imports sheath 32, and the external diameter of stay pipe mates with the internal diameter importing sheath, and the internal diameter of stay pipe mates with the external diameter of puncture needle; The external diameter of described seal wire mates with the internal diameter of puncture needle; The length of described sheath pipe assembly be less than puncture needle remove active joint after length.The implication of coupling is such, and such as nook closing member can mate and penetrates in puncture needle, without obvious gap between nook closing member and puncture needle inwall, and can ensure that again nook closing member is smooth and easy and penetrates.The front end of described conduit is tapered, and the length of conduit is 40cm, and the length of described special seal wire is 80-85cm.The tapered conduit in described front end conveniently enters narrow section, and catheter design becomes size can just by described stay pipe, obviously like this facilitates operation technique.Described conduit, special guidewire length are suitable, facilitate the carrying out of operation.
Described seal wire is platinum seal wire, and the head end of seal wire is soft, and it is harder that tail end compares head end.
The length that described puncture needle is removed after active joint is 20-25cm, and the length of sheath pipe assembly is 13-17cm.
When carrying out bile duct puncture, 22G puncture needle component is entered common hepatic duct, inject a little contrast agent, understand common hepatic duct situation out of shape.Judge that this puncture position well introduces seal wire afterwards, local skin cuts subsequently, then the active joint of puncture needle rear end is unclamped taking-up, along seal wire, puncture needle component introducing sheath pipe assembly that indwelling is good, after sheath pipe assembly enters into common hepatic duct, withdraw from seal wire and nook closing member.Injecting contrast agent by importing sheath, understanding the overall out of shape and narrow location of common hepatic duct.Then special catheter guide wire is introduced along stay pipe, by fitting through narrow section or entering duodenum.Give subsequently and placement inside-and-outside drainage or support, complete operation technique.
