Abstract
The utility model discloses a biliary tract puncturing device, which comprises a mini lead wire and an expanding pipe. The expanding pipe includes an inner cavity running through the front and the back of the expanding pipe since a coaxial flexible lateral hole expanding pipe, the inner cavity consists of a front inner cavity and a rear inner cavity, the diameter of the front inner cavity matches with that of the mini lead wire and smaller than that of the rear inner cavity, and a lateral hole communicated with the rear inner cavity is arranged on the lateral wall of the front end of an expanding pipe body. The biliary tract puncturing device can reduce operating procedures of a puncturing surgery, reduces pain and risk for a patient, decreases surgery time and can carry out radiography to understand biliary tract condition.
Description
Technical field
This utility model relates to the medical thrust apparatus, relates in particular to a kind of bile duct puncture device.
Background technology
Present puncture gatherer comprises micropuncture pin, micro-wire, convergent divergent channel, puncture successfully enter biliary tract after, need repeatedly expand liver puncture road, exchanging pipe, seal wire, increase the chance of patient's misery, hemorrhage, infection etc., the operation check.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model provides a kind of bile duct puncture device, reduces the program of operation, reduces patient's misery and risk, has reduced operating time, and the situation of the biliary tract of radiography understanding in real time.
To achieve these goals, the technical solution of the utility model is: a kind of bile duct puncture device, comprise micro-wire, convergent divergent channel, this convergent divergent channel comprises the inner chamber before and after running through, described convergent divergent channel is coaxial toughness side opening convergent divergent channel, described inner chamber is divided into forward and backward inner chamber, and the diameter of front interior cavity and micro-wire match and merge less than rear interior cavity, is provided with the side opening that is communicated with rear interior cavity in the front end side wall of expansion tube.
Described bile duct puncture device also comprises the coaxial rigid stay pipe that the rear interior cavity that is used for being inserted in coaxial toughness side opening convergent divergent channel supports.
Described bile duct puncture device also comprises the coaxial sheath pipe that is enclosed within the outer tape label of described coaxial toughness side opening convergent divergent channel, is connected with the two-way switch adapter in the rear end of this coaxial sheath pipe.
Compared with prior art, this utility model convergent divergent channel and sheath pipe two-in-one have reduced the program of operating, and have reduced patient's misery and risk, have reduced operation time; Contrast agent can be injected the bigger rear interior cavity of diameter, contrast agent is flowed out to the biliary tract from side opening, radiography is understood the situation of biliary tract in real time.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an assembly exploded view of the present utility model.
Fig. 2 is a coaxial side opening toughness convergent divergent channel sketch map of the present utility model.
Fig. 3 is the local enlarged diagram of front end of micro-wire of the present utility model, coaxial rigid stay pipe, coaxial toughness side opening convergent divergent channel and the combination of coaxial sheath pipe.
The specific embodiment
See also Fig. 1 to Fig. 3, the bile duct puncture device of present embodiment comprises the combination of micropuncture pin 1, micro-wire 2, coaxial rigid stay pipe 3, coaxial toughness side opening convergent divergent channel 4 and coaxial sheath pipe 5, coaxial toughness side opening convergent divergent channel 4 comprises the inner chamber 10 before and after running through, inner chamber is divided into forward and backward inner chamber, the diameter of front interior cavity and micro-wire 2 match and merge less than rear interior cavity, are provided with the side opening 9 that is communicated with rear interior cavity in the front end side wall of expansion tube.The bile duct puncture device also comprises the coaxial sheath pipe 8 that is enclosed within the outer tape label of coaxial toughness side opening convergent divergent channel, is connected with two-way switch adapter 7 in the rear end of this coaxial sheath pipe.The forward and backward inner-cavity structure that diameter is different makes it possible to contrast agent is injected the bigger rear interior cavity of diameter, then flows out to the biliary tract from side opening 9, and radiography is understood the situation of biliary tract in real time.
During use, earlier with micropuncture pin 1 at the predeterminated position into biliary tract that punctures, withdraw from micropuncture pin 1, by puncturing hole micro-wire 2 is extend into the target location; The front aperture 11 of coaxial toughness side opening convergent divergent channel 4 is aimed at micro-wire 2, make micro-wire 2 enter the intravital forward and backward inner chamber of pipe successively, advance coaxial toughness side opening convergent divergent channel 4 to enter biliary tract, realize the expansion of puncturing hole along micro-wire 2; When needing to support, in the rear interior cavity of coaxial toughness side opening convergent divergent channel, insert the coaxial rigid stay pipe 3 that is used to support; In order to prevent extraneous roentgenization, can outside coaxial toughness side opening convergent divergent channel 4, put the fixed coaxial sheath pipe 8 of a tape label 12; Inject contrast agent and prevent that contrast agent from leaking in coaxial toughness side opening convergent divergent channel for more convenient, behind the fixed coaxial sheath pipe of a tape label, connect a two-way switch adapter 7.
