Problems solved by technology

[0028] In this study, the traditional external drainage was changed to internal flow through the transformation of T tube (new T tube), which made it more physiological and solved the problems of bile loss caused by external drainage and the inconvenience of carrying drainage bags.

Embodiment Construction

[0030] Design Principles and Technical Keys

[0031] 1. It should be easy to operate when the new T-tube side tube is inserted into the jejunum.

[0032] 2. Fewer complications during extraction.

[0033] The main principle should be not to increase too much surgical operation and increase surgical complications due to internal drainage. Therefore, the measuring tube should be thin and unobstructed, not easy to be blocked, and the surrounding tissue is easy to form a sinus.

[0034] Manufacture of new T-tube

[0035] Cooperate with manufacturers. A side tube with an outer diameter of 5 mm, an inner diameter of 3 mm, and a length of 30 cm is added to the main tube 5 cm away from the T-shaped junction of the traditional T tube. This side tube is used to insert into the upper part of the jejunum. The side tube should be as thin as possible to facilitate extraction and avoid intestinal leakage, but it should be unobstructed to avoid blockage. It is easy to pull out and there ...

Abstract

The present invention relates to a new-type T-tube for drainage of surgical biliary tract operation. It is characterized by that on the main tube having 5 cm distance from T-shaped place of traditional T-tube a side tube whose outer diameter is 5 mm, inner diameter is 3 mm and length is 30 cm. Said side tube is used for inserting into upper part of the jejunum, and said side tube must be as fine as possible, but it must be smooth, and can not be blocked, and said side tube cn be easily drawn out, and can prevent enteric leakage.

Description

[0001] 1. Technical Field: Clinical Medicine 2. Background technology: [0002] T-tube drainage of the common bile duct is a common operation in biliary surgery. It is to drain the bile in the common bile duct from the T-tube to the drainage bag outside the body. Since Kehr first used the T-tube drainage operation in 1889, the common bile duct T-tube drainage operation has been used until now and has become a routine, which has not changed for more than a hundred years. [0003] The production and composition of bile [0004] Bile is secreted by hepatocytes and bile capillaries. [0005] The adult liver secretes about 800-1200ml of bile per day. [0006] Inorganic ions (mEqL) organic solute Na + (140~165) K + (3.8~5.8) Cl - (93~123) HCO 3 - (15~55) Ca 2+ (14~50) Mg 2+ (15~30) Bile acid (5~50mmol / L) Cholesterol (100~340mg / 100ml) Phospholipids (150~800mg / 100ml) Protein (25~500mg / 100ml) ...
