Description

Esophagus extension and anastomat capable of being accurately controlled in vitro

Technical Field

The invention belongs to the technical field of medical treatment, and belongs to a medical instrument.

Background

The esophagus prolonging technology is mainly applied to long-section deletion type congenital esophagus closure and treatment of esophageal stenosis caused by various reasons such as chemical burns, operations, wounds, tumors and the like. At present, the treatment of esophageal stenosis has certain difficulties, and the current treatment techniques comprise: the magnetic force extension and squeezing technology for suture traction in surgical resection and anastomosis replaces esophageal surgery with intestinal tubes, but all the modes have certain defects. Performing surgical excision anastomosis: the method is mainly suitable for normal esophagus anastomosis with a short distance, generally within 2cm, and has the defects of difficult anastomosis and more complications if the esophagus is lost more. Magnetic force lengthening and squeezing technology: 1 case is reported in China, but the defects that the magnetic force cannot be controlled, the magnetic force cannot act after a long distance, and premature anastomosis, squeezed esophagus rupture, pneumothorax, empyema and other thoracic cavity infections are easily caused by a short distance. Gastroesophageal surgery, the ultimate form of esophageal replacement, is associated with high complications. Esophageal dilatation technology: the expansion is carried out by using hard instruments such as a sacculus, a bougie and the like. The indications are narrow, and the traditional Chinese medicine composition is only suitable for patients with narrow esophagus and cannot be suitable for patients with esophageal loss. The effect is poor, and many children need to be dilated for several times or even tens of times. The diseased esophagus is still present.

The invention relates to a method for processing a semiconductor chip.

The technical principle is that the stress on human tissues can be prolonged. For example, 1. neck collar extends esophagus and tissue: the boao family of women is famous for the "long neck women". They wear the first copper collar two years later and the second collar from their 5 s. The collar is typically 8.5 mm in diameter. With age, the neck can be worn with 5 to 25 collars, and the final weight can reach 25 to 30 kg. 2. Magnetic force extension: the domestic research of Gaoya and Liushi Qi, etc. shows that the goal of prolonging the esophagus can be achieved by the anastomosis technology of magnetic squeezing, etc. It is shown that the aim of prolonging the tissues of the human body can be achieved by increasing the stress at the near-far end of the esophagus.

The metal corrugated pipe is a composite metal pipe which has a long history and is formed by coating metal, spiral grains are arranged outside a hollow part, electric wires with certain sizes can pass through the pipe hole, the metal corrugated pipe can be bent into a certain shape in a three-dimensional space and can keep the shape of the metal corrugated pipe, the length and the size of the metal corrugated pipe are basically stable when the metal corrugated pipe is bent, the bent metal corrugated pipe has certain supporting force and can support objects with certain weight, and the supporting force is controllable within a certain range. The surface is coated with plastic to protect the mucosa. Can be used for transmitting the force transmitted by the figure 6 and has the aim of balancing the stress of the two parts of the anastomat.
