Abstract
The utility model relates to a drainage tube for liver and gall diseases, which consists of a drainage tube body and an external interface locking device, wherein, the front end of the tube body is an arc provided with four to six drainage holes at the internal side, and the tube body is provided with a control line inside. The external interface locking device consists of a cylinder body and a rocker, and the control line is connected with a spanner through the rear end of the tube body and the cylinder body of the locking device to control the arc shape of the tube body. The drainage tube is in accordance with the physical characteristic of Chinese people and has convenient fixation and no sliding-off, which is beneficial for curing diseases and improving the life quality of patients and applicable to PTCD drainage, local or diffuse effusion drainage and internal radiation of biliary tumor.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of drainage tube of liver and gall diseases treatment usefulness.
Background technology
(percutaneous transhepaticcholangial drainage PTCD) is the common method of the obstructive jaundice that causes of treatment hepatocarcinoma, common hepatic duct cell carcinoma and cancer of pancreas to the guiding of B ultrasonic or X-ray through hepatic duct puncture and PTBD through skin down.This method is simple, clinical effectiveness is good, but has following contradiction at present as the main apparatus PTCD pipe of PTCD: import PTCD pipe costs an arm and a leg, and some kind not quite is fit to Chinese physical characteristic, homemade pipe is cheap, but pipe is hard, easily slippage, external drain do not have fixing, side opening is few.In view of the above, we have developed the PTCD pipe of suitable Chinese human model feature.
Summary of the invention
The purpose of this utility model is to propose a kind of suitable Chinese human model feature, and is difficult for the PTCD pipe of slippage, convenient fixing.
The PTCD pipe of this utility model design is made of body and external tapping locking device, and its structure as shown in Figure 1.Wherein, body 1 length is 20-50cm, and caliber is 2.7-4.0mm, the front end position shape in the arc-shaped of body, and circular diameter is 2.5-3.5cm.The inboard of circular body has 4-6 conduction hole 2.Be provided with a control line 3 in the body 1, its front end is fixed with the front port of pipe after passing body, and draw from the rear port of pipe its rear end, can cooperate with external tapping locking device 4, with the shape of stationary pipes.External tapping locking device 4 is made of a cylindrical shell 5, a locking rocking arm 6, and the front end of locking device 4 is connected with the rearward end of body 1.Its connected mode generally can be and is threaded.Control line 3 is drawn from the body rear port, passes the cylindrical shell 5 of locking device 4 and is connected with rocking arm 6, is provided with leakage prevention sheet 7 between the cinclides of control line 3 and cylindrical shell 5, and rocking arm 6 outwards unclamps, and control line 3 loosens; When tight, can fix the circular shape of body 1 front end by control line 3 tensions to the inboard for rocking arm 6.The rear port of external tapping locking device can be connected with syringe.
In this utility model, body 1 generally can adopt polyamine fat material, and to guarantee its intensity, the aperture of the conduction hole 2 of its front end generally can be about 4/5 of caliber; The front port place caliber of pipe progressively dwindles, and port diameter is generally 1.4-2mm.The control line 3 general polypropylene lines that adopt with higher-strength.
This PTCD pipe can adopt common Seldinger intubation technique, and body 1 is inserted bile duct or hydrops intralesional, through control line 3 controls, makes the front end position of body bend to circular shape, and is fixed on bile duct or hydrops intralesional, makes pipe be difficult for slippage.When needing drain, syringe is inserted the rear port of external tapping locking device 4, aspirate, hydrops just can pass through the forward conduction hole 2 of body, extracts out through piping.In the non-drain phase, can be with the sealing of external tapping locking device, in order to avoid bile etc. are excessive.
This PTCD pipe is mainly used in the PTCD drain, also can be used as the drain of interior various localities of body or diffusivity hydrops.Also can adopt this pipe to carry out the internal radiation of tumor of bile duct.
This PTCD pipe can be designed to different specifications and models as required.It is suitable for Chinese human model shape feature.During use, drain or close the envelope easy to operate, pipe is difficult for slippage, helps treatment of diseases, helps improving patient's quality of life.
Description of drawings
Accompanying drawing is a structural diagrams of the present utility model.
Number in the figure: 1 is body, and 2 is conduction hole, and 3 is control line, and 4 is external locking device, and 5 is the cylindrical shell of locking device, and 6 is locking rocker arm, and 7 is leakage prevention sheet.
The specific embodiment
Further describe this utility model below by embodiment.
If body 1 adopts polyamine fat material, length is 45cm, and caliber is 3.0mm, and body front end position is circular, and round diameter is 3cm.The front port diameter of pipe is 1.6mm; Circular inner side has 5 conduction holes 2 equably.The conduction hole diameter is 2.4mm; Control line 3 adopts the polypropylene line, and length is generally 55cm, and the front end place of its front end and body 1 is fixed; The diameter of the cylindrical shell 5 of external tapping locking device 4 is 5mm, length 6cm, and rocking arm one side of cylindrical shell has aperture, passes for control line 3, and the leading section of device 4 and the rear port shape of body 1 and size are mated, and connect by engage thread.Control line passes the aperture on the cylindrical shell 5, is connected with wrench 6.Above-mentioned parts assembly promptly gets the product of certain model of this utility model.
