Flexible Human Organ Expander

Abstract

The invention discloses a flexible human organ expander which comprises a fixed pipe, expanding rod components, a connecting ring, a tensioning rope and an elastic wire. The fixed pipe, the expanding rod components, the connecting ring, the tensioning rope and the elastic wire are connected in sequence. The expanding rod components are evenly distributed around the axis of the fixed pipe. Three small holes are respectively formed in a connecting block, transition blocks, a middle block, acting blocks and an ending block in each expanding rod component, and the tensioning rope and the elastic wire penetrate through the small holes. One end of the tensioning rope is fixed with one ending block and connects the connecting ring and the ending block together, then the tensioning rope penetrates through the whole expanding rod components, and finally the tensioning rope penetrates out of a small hole of the fixed pipe. The elastic wire is folded to be in a U shape, the two ends of the elastic wire respectively penetrate through the whole expanding rod components, and finally the elastic wire penetrates out of small holes of the fixed pipe. In the work process, the fixed pipe is fixed, the tensioning rope and the elastic wire are tensioned, expanding rods can be bent to a certain shape, the expanding rods form a space body, and the human organ is expanded. A channel is formed in the fixed pipe, and allows a surgical instrument or an endoscope or other tools to enter the organ for the operation.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a flexible human body organ expander. Background technique [0002] Since the 20th century, as people have put forward higher and higher requirements for the diagnosis and treatment of their own diseases, especially the formation and development of minimally invasive surgery, the medical community has proposed that the so-called minimally invasive surgery should have the characteristics of small surgical trauma, light scars, and fast recovery. With the advancement of robot technology and related disciplines, a group of minimally invasive surgical robots that can replace surgeons to varying degrees have emerged, and it has become a reality to use surgical robots to complete minimally invasive surgery. [0003] In 1995, Frederick established Intuitive Surgical in cooperation with NASA and Stanford Research Institute, and manufactured the "DaVinci" robotic surgery system. ...

AI Technical Summary

Problems solved by technology

[0004] However, in the research of numerous minimally invasive surgical systems, people mostly focus on how to reduce the size of surgical instruments and increase the flexibility of manipulators, etc., while ignoring the research on organ expansion.

At present, the expansion of organs is mostly done by using gas, liquid and other media, but the use of gas, liquid and other media has high requirements on various indicators of the human body, and is prone to some negative effects, causing harm to the human body.
