Tissue pushing and pressing expansion sheath plate

Abstract

The invention discloses a tissue pushing and pressing expansion sheath plate. The tissue pushing and pressing expansion sheath plate comprises an expansion sheath tube, wherein the expansion sheath tube is arranged in an inner cavity mode, and a balloon cavity is formed in the head of the expansion sheath tube and arranged in a sealing mode; a plurality of balloon grooves communicating with the outside are formed in the side wall of the balloon cavity, and expansion balloons are arranged at the balloon grooves in the balloon cavity in a one-to-one correspondence and sealing mode; and air is injected into the balloon cavity, and the expansion balloon swells from the balloon grooves of the balloon cavity to the outer side of the expansion sheath tube. When the pressure intensity of the balloon cavity is reduced, the expansion balloon is adsorbed and clung to the balloon cavity, so that the expansion sheath tube can conveniently extend into diseased tissues of a patient. When the pressure intensity of the balloon cavity is increased, the expansion balloon swells to the outer side, and the purpose of rapidly expanding the diseased tissue of the patient is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tissue pushing and expanding sheath plate. Background technique [0002] When doing inspection, diagnosis or surgical treatment, it is necessary to stretch the human cavity and tissue first, and then put in other surgical instruments for inspection or treatment. At present, the commonly used expander is to make the division and proliferation of tissue and epidermal cells and the intercellular gap to expand through the expansion mechanism to the local area, thereby increasing the tissue area. After taking out the expansion bag, the newly added skin soft tissue can be used for tissue repair and organ repair. Reinvented. However, the existing dilator has a complex structure and is difficult to operate, and the dilator can only expand the surface of human tissue, but cannot go deep into the inside of the human body; at the same time, it cannot effectively observe the inter...
