Sealed and pressure-controllable pig stomach fixator

Abstract

The invention discloses a sealed and pressure-controllable pig stomach fixator which comprises a container body, a fixing mechanism used for fixing an isolated pig stomach is arranged in the container body, and the fixing mechanism comprises a first fixing assembly used for fixing an esophagus section of the isolated pig stomach and a second fixing assembly used for fixing a duodenum section. The container body is internally provided with a sealing cavity for accommodating the isolated pig stomach, and the container further comprises a first pressure input piece for inputting pressure into the sealing cavity and a second pressure input piece for inputting pressure into the isolated pig stomach. According to the sealed and pressure-controllable pig stomach fixator provided by the invention, the pressure in the sealed cavity can be adjusted and controlled through the first pressure input piece, and the pressure in the isolated pig stomach can be adjusted and controlled through the second pressure input piece; in this way, the isolated pig stomach can simulate different environments for an operator to carry out model training, and the effect obtained by operating the training model by a digestive endoscopy teacher is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a sealed and pressure-controllable pig stomach fixer. Background technique [0002] At present, the control strategy for neoplastic diseases has shifted from passive treatment to active prevention and early identification. With the improvement of people's health awareness and the improvement of endoscopic diagnosis and treatment, the diagnosis and treatment of early gastric cancer by domestic digestive endoscopists are also improving year by year. [0003] As a new minimally invasive treatment technique, endoscopic submucosal dissection (ESD) has been gradually applied in clinic, which expands the scope of indications of endoscopic submucosal resection (EMR) and avoids the lesions faced by EMR technology. Residual and recurrence problems. However, ESD has extremely high requirements for endoscopists, and serious complications such as perforation and bleeding...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, during the simulated training process of digestive endoscopy using pig stomach, the fixing devices of the pig stomach model only fix the pig stomach, but there is a big difference between the pig stomach model and the digestive tract of the human body. For example, the pressure inside and outside the human digestive tract is different from the pressure inside and outside the pig stomach model. Due to the difference in the simulated bionic environment, digestive endoscopists often use the operation training model to perform ESD training poorly, and the expected effect cannot be achieved.
