Abstract
The utility model discloses an external drainage tube of a hilar bracket. The external drainage tube comprises a main bracket tube; the upper end of the main bracket tube is branched to form a left bracket tube and a right bracket tube; the included angle Alpha between the main bracket tube and the left bracket tube is 135 degrees; the included angle Beta between the main bracket tube and the right bracket tube ranges from 90 degrees to 150 degrees; the lower end of the main bracket tube is expanded; a drainage adjusting hole with the diameter of 2 mm is formed at the crotch of the left and the right bracket tubes; a plurality of drainage holes with the diameter of 1 mm are formed at the crotch between the main bracket tube and the left bracket tube and that between the main bracket tube and the right bracket tube; the main bracket tube ranges 70 cm to 80 cm in length and ranges from 5.3 mm to 4 mm in diameter; the left and the right bracket tubes are 6 cm in length and gradually become thinner from the branched ends to the tail ends in diameter; the branched ends are same as the main bracket tube in diameter, and the diameters of the tail ends are 50 to 65 percent of those of the branched ends. The external drainage tube of the hilar bracket has a reasonable structure and strong clinical practicality, fits the hilar structure, is placed conveniently, effectively solves the problems that anastomosis leakage and anastomotic stenosis are easy to cause, and secondary operation or multiple operations are needed to be performed in the prior art, and relives the pain of the patients.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of hepatic portal portion support drainage tube.
Background technology
After hepatic portal portion tumour patient carried out tumor resection, its hilar bile duct need form, and is thinner like left and right sides common hepatic duct, then is prone to produce gallbladder and leaks and anastomotic stricture, need carry out secondary or repeatedly operation, can cause serious injury to patient.In addition, along with laparoscopic surgery technology being widely used clinically, the hilar bile duct damage also happens occasionally; When common hepatic duct is thin, be prone to especially take place; The gallbladder intestinal of need going during the hilar bile duct major injury coincide, because common hepatic duct is thinner, also is prone to produce gallbladder after the gallbladder intestinal coincide and leaks and anastomotic stricture.
Summary of the invention
For overcoming the weak point of prior art; This utility model provide a kind of be used for hilar bile duct damage need row gallbladder intestinal to coincide and oncosis People's Bank of China of hepatic portal portion tumor resection after; Carry out that hilar bile duct is shaped and left and right sides common hepatic duct when thin, and the hepatic portal portion support drainage tube of placing.
This utility model solves the technical scheme that its technical problem adopted: comprise the main support pipe, main support pipe upper end is branched into left socle pipe and right support pipe; Angle between main support pipe and left socle pipe is 135 °, and the angle β between main support pipe and right support pipe is 90 °～150 °; Expand the lower end of main support pipe, is convenient to external drainage bag; At left socle pipe and the right support pipe crotch drain adjustment hole that to be provided with a diameter be 2mm, be convenient to drain on the one hand, be convenient on the other hand adjust the angle between left socle pipe and the right support pipe, increase its scope of application.
Above-mentioned main support pipe and left socle pipe, right support pipe intersection region are provided with the conduction hole that several diameters are 1mm, with further enhancing drainage effect.
The length of above-mentioned main support pipe is 70～80cm, and caliber is 5.3～4mm; The length of left socle pipe and right support pipe is 6cm, its caliber from divergent ends to end from the coarse to fine, the divergent ends caliber is identical with the main support pipe, terminal caliber is 50～65% of a divergent ends caliber.
The beneficial effect of this utility model is: it is rational in infrastructure; Meet hepatic portal portion structure; It is convenient to place, clinical practice property is strong, has solved the difficult problem that prior art is prone to anastomotic leakage and anastomotic stricture, needs secondary repeatedly to perform the operation effectively; Alleviate patient's misery, had higher value for applications.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure, 1 is that main support pipe, 2 is that left socle pipe, 3 is that right support pipe, 4 is that drain adjustment hole, 5 is conduction hole.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is described further.
Embodiment one:
As shown in Figure 1, this utility model embodiment comprises the main support pipe of being processed by medical silica-gel 1, and main support pipe 1 upper end is branched into left socle pipe 2 and right support pipe 3; The angle that main support pipe 1 and left socle pipe are 2 is 135 °, and the angle β between main support pipe 1 and right support pipe is 90 °; Expand the lower end of main support pipe 1, is convenient to external drainage bag; At left socle pipe 2 and the right support pipe 3 crotches drain adjustment hole 4 that to be provided with a diameter be 2mm, be convenient to drain on the one hand, be convenient on the other hand adjust the angle between left socle pipe 2 and the right support pipe 3, increase its scope of application.Above-mentioned main support pipe 1 is provided with the conduction hole that several diameters are 1mm with left socle pipe 2, right support pipe 3 intersection regions, with further enhancing drainage effect.The length of above-mentioned main support pipe 1 is 80cm, and caliber is 5.3mm; The length of left socle pipe 2 and right support pipe 3 is 6cm, its caliber from divergent ends to end from the coarse to fine, the divergent ends caliber is identical with main support pipe 1, terminal caliber is 3mm.
During use, left socle pipe of this utility model 2 and right support pipe 3 are placed respectively in patient's the left and right common hepatic duct, the length of left socle pipe 2 and right support pipe 3 can be pruned according to the practical situation of patient's common hepatic duct; Place left socle pipe 2 with right support pipe 3 and accomplish coincide after, jejunum is opened aperture and main support pipe 1 is drawn purse string suture apart from anastomotic stoma 40cm place; And puncture draws outside the stomach wall, and intestinal wall and peritoneum are properly fixing; Lower end at main support pipe 1 connects drainage bag in addition.This utility model should be placed more than six months, can effectively prevent anastomotic leakage and anastomotic stricture, avoided need carrying out in the prior art secondary or the problem of operation repeatedly, alleviated patient's misery.
Embodiment two:
The angle that described main support pipe 1 of this utility model embodiment and left socle pipe are 2 is 135 °, and the angle β between main support pipe 1 and right support pipe is 90 °; The length of main support pipe 1 is 70cm, and caliber is 4mm; The divergent ends caliber of left socle pipe 2 and right support pipe 3 is identical with main support pipe 1, and terminal caliber is 2.5mm.Other is with embodiment one.
Method for using is with embodiment one.
