Technical Field
The invention relates to the technical field of medical instruments, in particular to a small intestine nutrition isolation and weight reduction tube.
Background
Obesity refers to a degree of significant overweight with an excessively thick fat layer. Excessive accumulation of fat in the body due to excessive food intake or altered metabolism of the body causes excessive weight gain and causes pathological, physiological changes or latency in the human body. However, obesity not only affects the beauty of human body and causes inconvenience to human life, but also causes many damages, such as increased risk of cardiovascular diseases, affected function of digestive system, affected function of endocrine system, increased risk of cancer, susceptibility to joint soft tissue injury, and the like. The small intestine is the primary site for food digestion and absorption, and reducing the absorption of nutrients by the small intestine will help reduce weight.
Chinese patent document CN101036599A discloses a membrane tube for isolating and reducing weight of small intestine, which comprises a strip-shaped membrane tube and a self-expansion device, wherein a funnel-shaped inflatable sac ring which can be placed in the stomach of a human body is connected with one end of the strip-shaped membrane tube through a connecting line, so that the strip-shaped membrane tube is fixed and prevented from moving in the small intestine. The small intestine nutrition isolation weight-reducing membrane tube completely shields a section of small intestine in which the weight-reducing membrane tube is placed, so that nutrition absorption of the section of small intestine is prevented, and the weight-reducing effect is achieved, however, friction damage to tissues at the gastrointestinal junction caused by long-term time can be caused, the capacity of the section of small intestine for absorbing nutrient substances is completely lost, and permanent damage can be brought to a patient; secondly, when the weight-reducing membrane tube is taken out, secondary operation is needed, which causes secondary pain to patients.
