Description

Technical Field

[0001] This utility model relates to the field of biological tissue cutting technology, specifically a novel Wharton's gum extraction device. Background Technology

[0002] The preparation of umbilical cord-derived mesenchymal stem cells requires the extraction of Wharton's jelly from umbilical cord tissue. The key technical aspect of Wharton's jelly extraction lies in the composition and structural characteristics of the umbilical cord tissue. Umbilical cord tissue exhibits a structure characterized by "randomly coiled polysaccharide chains," and its composition is as follows: Umbilical cord: The most prominent part of the umbilical cord is the umbilical cord, which typically includes two umbilical arteries and one umbilical vein; Mucus tissue: The interior of the umbilical cord is filled with a substance called mucus tissue or Wharton's jelly, a gel-like substance rich in polysaccharides (mainly Wharton's jelly) and collagen; Umbilical cord membrane: The umbilical cord is surrounded by the umbilical cord membrane, a thin membrane composed of the amnion and chorion, which helps maintain the structural integrity of the umbilical cord and provides some protection.

[0003] Currently, Wharton's jelly extraction involves using tweezers to tear open the umbilical cord along its spiral structure (the randomly coiled structure of the polysaccharide chains), removing the umbilical artery and vein, then using tweezers in the left hand to hold the dissected umbilical cord tissue in place, while using tweezers in the right hand to grasp the Wharton's jelly. This method is inefficient: a large portion of the Wharton's jelly is not completely extracted; it is time-consuming; prolonged use of tweezers for delicate manipulation can cause occupational injuries or discomfort (such as wrist pain, finger cramps, neck and shoulder fatigue, and eye strain); and training technicians for this skill is costly. Therefore, it is necessary to provide an umbilical cord Wharton's jelly extraction device to solve these technical problems. Utility Model Content
