Double-balloon anastomat for digestive tract reconstruction

Abstract

A double-balloon anastomat for digestive tract reconstruction comprises a nutrient canal. The nutrient canal is sleeved with an inflatable upper-end balloon and a lower-end balloon, the lower-end balloon can be placed below the narrow portion of the digestive tract to be reconstructed along with the nutrient canal before being inflated, and the lower-end balloon and the upper-end balloon located above the narrow portion can clamp and anastomose the narrow portion together after being inflated. According to the invention, the double balloons are used for inflation anastomosis, the stable force applied to the tissue in the anastomosis process can be ensured, the balloons are arranged on the nutrition tube, the nutrition channel can be maintained in the anastomosis process, the life quality of a patient is improved, and compared with a magnet, the balloons are light in weight, so that the normal tissue around the squeezed tissue is basically not pulled, and the device can be suitable for different clinical scenes by adjusting the size of the balloon.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a double-balloon stapler for digestive tract reconstruction. Background technique [0002] The traditional treatment methods for digestive tract strictures are surgical treatment or mechanical expansion, which cause great pain to patients and ineffective curative effect. For digestive tract reconstruction after esophageal or gastric cancer resection, there are mainly two methods: traditional manual suture and mechanical anastomosis. Manual suturing takes a long time, while mechanical anastomosis is likely to cause anastomotic tear when withdrawing, and the treatment effect is not ideal. The magnetic anastomosis technique proposed by Obora in 1978 has the advantages of continuous reconstruction of the digestive tract and high safety. However, during the magnetic anastomosis process, there is a continuous increase in the compression force on the tissue. In the later stage...

Problems solved by technology

However, during the magnetic anastomosis process, there is a continuous increase in the compression force on the tissue. In the later stage of the anastomosis, the distance between the magnets decreases, and the magnetic force between the magnets increases, which may lead to the premature loss of the compressed tissue and the formation of anastomotic leakage, which is not conducive to the formation of the anastomosis.
