Jejunum nubrient canal imbedded during Ivor-Lewis radical resection of esophageal carcinoma

Abstract

The invention discloses a jejunum nubrient canal imbedded during Ivor-Lewis radical resection of esophageal carcinoma. The jejunum nubrient canal comprises a traction tube, a traction tube opening, a jejunum nubrient canal body, a detachable nubrient canal opening and a guide wire, wherein the guide wire is arranged in the jejunum nubrient canal body, the lower end of the jejunum nubrient canal body is in an arc shape, a long thread is arranged on the outer wall of the upper end of the jejunum nubrient canal body, and the detachable nubrient canal opening is inserted into the upper end of the jejunum nubrient canal body through a metal connection end with an anti-slip groove. The traction tube opening is formed in the upper end of the traction tube, a long thread is arranged on the inner wall of the lower end of the traction tube, and the lower end of the traction tube is connected with the upper end of the jejunum nubrient canal body through a threaded clamping port to form a hollow round tube. The jejunum nubrient canal is simple in structure and easy to operate. Furthermore, by means of the jejunum nubrient canal, operation processes of Ivor-Lewis radical resection of esophageal carcinoma under a full-chest peritoneoscope can be simplified. The jejunum nubrient canal can be imbedded in the jejunum safely, quickly, conveniently and accurately through a jejunum nubrient canal upside down imbedding method.

Description

technical field [0001] The invention relates to a medical device, in particular to a jejunum nutrition tube. Background technique [0002] After gastrointestinal surgery, it is often impossible to eat normally for a long period of time, and nutritional support is needed to maintain vital signs and basic metabolic needs. Enteral nutrition has gradually replaced parenteral nutrition to avoid catheter and nutritional metabolism complications and improve the safety and effectiveness of nutritional support. [0003] At present, the commonly used method of placing the jejunal nutrition tube through the nose is to insert the jejunum nutrition tube through the nostril after the operation is anastomotic. 30cm below the ligament. [0004] The jejunal nutrition tube placed through the nose does not cause new trauma, and the insertion method is simple, fast, and convenient. However, in the operation of the right thorax and epigastrium with two incisions (Ivor-Lewis) and total thoracic...

AI Technical Summary

Problems solved by technology

[0006] The traditional jejunal nutrition tube body cannot be separated from the tube mouth, and it is easy to leak after cutting it off. It also lacks a traction tube that can be connected to the tube body. Silk thread is often used instead, which may easily cause the nutrition tube mouth to damage the mucous membrane.

Therefore, it is difficult to insert the jejunum nutrition tube by inversion method, and the traditional jejunum nutrition tube has no swelling at the tube head and no bamboo-like protrusions on the tube body. It is difficult to feel the jejunum nutrition tube when the hand-assisted nutrition tube passes through the pylorus. , the incision is small and only allows two fingers to pass through, which is especially difficult
