Drainage device for hepatobiliary surgery department

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a hepatobiliary surgery drainage device which comprises a main body, a bandage used for limiting the main body is arranged on the outer side of the main body, and a sliding seat capable of adjusting the use position in a sliding mode is arranged on the outer side of the bandage. After the bandage sleeves the outer side of the skin of a patient and the use position of the sliding seat is adjusted, the limiting belt sleeves the outer side of the positioning ring, and the rubber pad is clamped and connected into the clamping groove, so that one end of the main body can be fixed, the structure is simple, no adhesive tape is needed, residual impurities are avoided, and wound pain caused by pulling the skin of the patient is prevented; one end of the main body is sleeved with the clamping sleeve, the supporting rod is rotated, at the moment, the sliding sleeve is pulled to enable the triangular spring washer to contract, and the clamping sleeve can be automatically clamped and connected into the limiting groove through elasticity to fix the supporting rod. The use angle of the main body can be conveniently adjusted, so that the main body is kept in an optimal suction state, discomfort of a patient is avoided, and the use effect is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a drainage device for hepatobiliary surgery. Background technique [0002] Hepatobiliary surgery mainly studies hepatocellular carcinoma, hepatolithiasis, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis, which are major diseases that seriously threaten the health of Chinese people. It is excreted from the original place to prevent accumulation in the body cavity or surgical field, secondary compression symptoms, infection or tissue damage. Therefore, a drainage device for hepatobiliary surgery is often used in the treatment process. [0003] The original device requires a lot of tape to fix the drainage tube on the outside of the patient's skin. When it is removed, it will leave more impurities and pull the patient's skin, causing pain. Moreover, the drainage tube cannot be fixed in different places during use. The angle of the dra...

Problems solved by technology

[0003] The original equipment requires a lot of adhesive tape to fix the drainage tube on the outside of the patient's skin. When it is taken out, more impurities will remain and the patient's skin will be pulled and cause pain. In addition, it is impossible to fix the drainage tube on different parts during use. Angle, causing the position of the drainage tube to be deflected and difficult to fix, causing discomfort to the patient, and when the drainage tube is taken out, there will be residual fluid on the surface, which is easy to drip and cause bacteria to spread and cause poor infection, and when there is too much bile that cannot be contained, it needs to be replaced Containers are cumbersome
