Abstract
Description
Technical Field
[0001] This utility model relates to the field of Wharton's glue cutting technology, specifically to a tool for cutting Wharton's glue in the umbilical cord. Background Technology
[0002] Wharton's jelly is a special gel-like connective tissue found within the umbilical cord, primarily wrapping and protecting the blood vessels (umbilical vein and umbilical artery) within the cord. Composed of mucopolysaccharides, collagen, and a small number of cells, it functions as a buffer, support, and prevents compression of blood vessels, making it crucial for fetal development.
[0003] Existing methods for cutting Wharton's jelly from umbilical cords are mostly manual. However, manual operation makes it difficult to precisely control the position of each cut, resulting in tissue fragments of varying sizes. Excessively large fragments hinder cell migration and expulsion, while fragments that are too small tend to float during culture, directly impacting the subsequent culture effect and efficiency of mesenchymal stem cells. Therefore, to overcome these shortcomings, we propose a tool for cutting Wharton's jelly from umbilical cords. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application proposes a tool for cutting Wharton's jelly in umbilical cords. Through a series of structures, this technical solution features convenient fixed-length cutting of Wharton's jelly.
[0005] This utility model provides the following technical solution: a tool for cutting Wharton's jelly in the umbilical cord, comprising a positioning block, a limiting block fixedly connected to the top of the positioning block, a pair of movable blocks provided inside the limiting block, a movable opening on the positioning block, a connecting block fixedly connected to the bottom of the movable block, the bottom of the connecting block passing through the movable opening and fixedly connected to a limiting chamber, a cutting blade provided inside the limiting chamber, and a pair of first bolts passing through the side wall of the limiting chamber, a threaded groove matching the first bolts being provided on the side wall of the cutting blade, a measuring ruler fixedly connected to the inner wall of the limiting block, an observation block fixedly connected to the top of the movable block, and an adjustment mechanism provided on one side of the limiting chamber.
[0006] As a preferred embodiment of this utility model, a stabilizing block passes through the pair of movable blocks, and the two side walls of the stabilizing block are fixedly connected to the inner wall of the limiting block.
[0007] As a preferred embodiment of this utility model, the adjustment mechanism includes a pair of rectangular tubes, which are fixedly connected to the outer wall of the positioning block. An adjustment block is provided inside the rectangular tubes, and one side of the adjustment block penetrates the side wall of the positioning block and is fixedly connected to the side wall of the limiting chamber.
[0008] As a preferred embodiment of this utility model, the top of the rectangular tube is through which a second bolt passes, and the top of the adjusting block is provided with several slots that match the second bolt.
[0009] As a preferred embodiment of this utility model, the surface of the pair of adjustment blocks is provided with anti-slip texture, and a plurality of the slots are equidistantly distributed on the top of the adjustment blocks.
[0010] As a preferred embodiment of this utility model, the surface of the limiting block is provided with anti-slip texture.
[0011] The beneficial effects of this utility model are:
[0012] 1. By adjusting the block, limiting chamber, cutting blade, measuring ruler, and observation block, and using the relative position of the observation block and measuring ruler, the spacing between a pair of cutting blades is obtained. Once the spacing between the pair of cutting blades is appropriate, the second bolt is tightened until it is engaged in the slot, thus fixing the position of the pair of cutting blades. Then, the limiting block is held and pressed against the pair of cutting blades, and the pair of cutting blades are used to cut the Wharton's jelly of the umbilical cord, thereby obtaining multiple tissue blocks of the required length and improving the convenience of cutting the Wharton's jelly of the umbilical cord.
[0013] 2. By setting up the limiting chamber, the cutting blade, and the first bolt, when it is necessary to replace the cutting blade, unscrew the first bolt, pull the cutting blade downwards, insert the new cutting blade into the limiting chamber, and then tighten the first bolt again to complete the replacement of the cutting blade and ensure the cutting efficiency of the tool.

[0020] Example
[0021] like Figures 1 to 4 As shown, a tool for cutting Wharton's jelly in the umbilical cord includes a positioning block 1, a limiting block 2 fixedly connected to the top of the positioning block 1, a pair of movable blocks 3 inside the limiting block 2, a movable opening 4 on the positioning block 1, a connecting block 5 fixedly connected to the bottom of the movable block 3, the bottom of the connecting block 5 passing through the movable opening 4 and fixedly connected to a limiting chamber 6, a cutting blade 7 inside the limiting chamber 6, and a pair of first bolts 8 passing through the side wall of the limiting chamber 6, a threaded groove matching the first bolts 8 on the side wall of the cutting blade 7, a measuring ruler 9 fixedly connected to the inner wall of the limiting block 2, an observation block 10 fixedly connected to the top of the movable block 3, and an adjustment mechanism on one side of the limiting chamber 6.
[0022] In this embodiment, the hand-held adjustment block 13 moves the limiting chamber 6 and the cutting blade 7. During this process, the relative position of the block 10 and the measuring ruler 9 is observed to obtain the distance between the pair of cutting blades 7 until the distance between the pair of cutting blades 7 is appropriate. A stabilizing block 11 passes through the pair of movable blocks 3. The two side walls of the stabilizing block 11 are fixedly connected to the inner wall of the limiting block 2. The adjustment mechanism includes a pair of rectangular tubes 12. The rectangular tubes 12 are fixedly connected to the outer wall of the positioning block 1, and an adjustment block 13 is provided inside the rectangular tubes 12. One side of the adjustment block 13 passes through the side wall of the positioning block 1 and is fixedly connected to the side wall of the limiting chamber 6.
[0023] In this embodiment, the position of the cutting blade 7 can be limited by the setting of the second bolt 14 and the slot 15. The top of the rectangular tube 12 is through the second bolt 14. The top of the adjusting block 13 is provided with several slots 15 that match the second bolt 14. The surface of a pair of adjusting blocks 13 is provided with anti-slip texture. Several slots 15 are equidistantly distributed on the top of the adjusting block 13. The surface of the limiting block 2 is provided with anti-slip texture.
[0024] Working principle: During use, hold the adjusting block 13 to move the limiting chamber 6 and the cutting blade 7. During this process, observe the relative position of the block 10 and the measuring ruler 9 to obtain the distance between the pair of cutting blades 7. After the distance between the pair of cutting blades 7 is appropriate, tighten the second bolt 14 until the second bolt 14 is inserted into the slot 15, thereby fixing the position of the pair of cutting blades 7. Then, hold the limiting block 2 and press the pair of cutting blades 7 with the limiting block 2. Then, cut the Wharton's jelly of the umbilical cord with the pair of cutting blades 7 to obtain multiple tissue blocks of the required length. When it is necessary to replace the cutting blade 7, unscrew the first bolt 8, pull the cutting blade 7 downward, insert the new cutting blade 7 into the limiting chamber 6, and tighten the first bolt 8 again to complete the replacement of the cutting blade 7.
