Abstract
The utility model discloses a transhepatic biliary drainage pipe, belonging to the technical field of a medical machine. The transhepatic biliary drainage pipe comprises a pipe body; a tapered head is arranged at one end of the pipe body, and a cylinder is arranged at the other end of the pipe body; the tapered head is connected with a drainage pipe made of an elastic material; a drainage hole is arranged on the drainage part; a supporting part for supporting the drainage part is arranged on the pipe body; an expanding and supporting part for expanding and supporting the drainage part is arranged on the tapered head; the expanding and supporting part comprises a mounting part; a plurality of elastic arms are arranged on the mounting part; the free end of each elastic arm is fixedly connected with a control secondary wire for controlling the elastic arms to expand or close up; the control secondary wire is connected with one control bus; the control bus passes out of the cylinder through the pipe body; and a control switch for controlling a position of the control bus is arranged on the cylinder. With the adoption of the structure, the size of the drainage part is controlled by controlling the size of the expanding and supporting part, so that the drainage part is convenient to limit at a demanded part and is prevented from slipping.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of liver and gall drainage tube.
Background technology
The structure of present liver and gall drainage tube is normally used a body, and an end of body is taper and is provided with some side openings, interts in vivo when conveniently use the end of taper; Side opening is used for body fluid such as bile are introduced in the body, and conical head is connected with control line, when body gets into predetermined position; Through control line that tapered end is crooked, be used for spacingly, prevent body slippage in the body; Control line is when pulling curved tapers end bent; Use very inconvenience, wayward bending direction departs from the anticipation position easily.
Summary of the invention
This utility model technical problem to be solved is: a kind of spacing drainage tube of liver and gall easily is provided.
For solving the problems of the technologies described above, the technical scheme of this utility model is: a kind of liver and gall drainage tube comprises body; Said body one end is provided with conical head, and the other end is provided with cylindrical shell, and said conical head connects the drain portion of being processed by elastomeric material; Said drain portion is provided with conduction hole, and said body is provided with the support portion of supporting said drain portion, and said conical head is provided with the expansion support part that is used to expand the said drain of support portion; Said expansion support part comprises installation portion; Said installation portion is provided with some elastic arms, the control branch line that the free end of said every elastic arm is fixedly connected with the said elastic arm expansion of control or draws in, and said control branch line is connected on the control bus; Said control bus passes said cylindrical shell by body, and said cylindrical shell is provided with the said control bus control of position switch of control.
As a kind of preferred, the quantity of said elastic arm is the 2-6 root.
Owing to adopted technique scheme, expanding the support part can be with the width of drain portion to extending out support, thereby convenient spacing; Can control the degree that expands the support part expansion through control bus; Thereby can confirm the size of drain portion expansion, can be through gauge tap with the fixed-site of control bus, because after the expansion support of drain portion; The size of position conduction hole on it also enlarges thereupon, thereby can accelerate the speed of drain.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the user mode figure of this utility model embodiment;
Among the figure: 1, conical head; 2, installation portion; 3, drain portion; 4, elastic arm; 5, the support portion; 6, body; 7, the control branch line; 8, control bus; 9, cylindrical shell; 10, gauge tap.
The specific embodiment
As depicted in figs. 1 and 2, a kind of liver and gall drainage tube comprises body 6; Said body 6 one ends are provided with conical head 1, and the other end is provided with cylindrical shell 9, and said conical head 1 connects the drain portion 3 of being processed by elastomeric material; Said drain portion 3 is processed by elastomeric material usually, and said drain portion 3 is provided with conduction hole, and said body 6 is provided with the support portion 5 of supporting said drain portion 3; Said conical head 1 is provided with the expansion support part that is used to expand the said drain of support portion 3, and said expansion support part comprises installation portion 2, and said installation portion 2 is provided with some elastic arms 4; The quantity of said elastic arm 4 is preferably the 2-6 root, is 4 elastic arms 4 shown in Fig. 1 and Fig. 2, and elastic arm 4 is oppositely arranged in twos; The control branch line 7 that the free end of said every elastic arm 4 is fixedly connected with said elastic arm 4 expansions of control or draws in; Said control branch line 7 is connected on the control bus 8, and said control bus 8 passes said cylindrical shell 9 by body 6, and said cylindrical shell 9 is provided with the said control bus 8 control of position switches 10 of control.
During original state, control bus 8 tensions make the width of drain portion 3 be no more than body 6 width elastic arm 4 gatherings; With the control bus fixed-site of 8 this moments, body 6 is inserted the position that human body needs drain with gauge tap 10, gauge tap 10 removals this moment are fixing to control bus 8; Control bus 8 is lax, elastic arm 4 is outwards opened, make 3 expansions of drain portion; When being expanded to correct position, through gauge tap 10 with control bus 8 fixed-site.
Claims (2)
1. the liver and gall drainage tube comprises body, and said body one end is provided with conical head; The other end is provided with cylindrical shell, it is characterized in that: said conical head connects the drain portion of being processed by elastomeric material, and said drain portion is provided with conduction hole; Said body is provided with the support portion of the said drain of support portion; Said conical head is provided with the expansion support part that is used to expand the said drain of support portion, and said expansion support part comprises installation portion, and said installation portion is provided with some elastic arms; The control branch line that the free end of said every elastic arm is fixedly connected with the said elastic arm expansion of control or draws in; Said control branch line is connected on the control bus, and said control bus passes said cylindrical shell by body, and said cylindrical shell is provided with the said control bus control of position switch of control.
