Problems solved by technology
[0005] However, although the multi-head scissors can improve the cutting efficiency, there are also unsatisfactory points: the tissue fragments separated by shearing are easy to adhere to each scissor head, and at the same time, due to the small gap between two adjacent scissor heads Small, making it difficult to remove tissue fragments caught between two adjacent scissor heads

Embodiment 1）
[0019] This embodiment is a kind of tissue crushing scissors for preparing human stem cells, see Figure 1 to Figure 7 As shown, two scissor handles 1, two scissor heads 2 and two dandruff combs 3 are included. The end of each scissors head is fixedly connected with a corresponding scissors handle.
[0020] Each scissor head 2 comprises five scissor blades 21 arranged side by side, and the root ends of the five scissor blades are connected by a pin 22; two scissor heads are connected by a rotating shaft 4; It is equivalent to five ordinary scissors, so compared with the traditional scissors with a single scissor blade, it can effectively improve the efficiency of tissue crushing.
[0021] See figure 2 As shown, each scissor handle 1 is provided with a pin shaft 11 and a support frame 12 for supporting the pin shaft. In this embodiment, each scissors handle includes a metal base 14 and a plastic sleeve 15 sheathed on the metal base; each supporting frame and a corresponding...

The invention discloses a tissue breaking shear for preparing human body stem cells. The tissue breaking shear comprises two shear handles, two shear heads and two anti-dandruff combs. Each shear handle is provided with a pin shaft and a supporting frame used for supporting the pin shaft. Each anti-dandruff comb comprises a comb handle, a comb rod and a comb brush. Each comb handle is located at the end, away from the corresponding shear head, of the corresponding comb rod, and each comb brush is located at the end, close to the corresponding shear head, of the corresponding comb rod. The comb rods are provided with guide holes penetrating the comb rods in the transverse direction. The pin shafts are located in the guide holes of the corresponding comb rods. Six comb teeth are arranged on each comb brush so that five brush grooves can be formed, and each comb brush can move till five shear blades of the corresponding shear head enter the corresponding brush grooves correspondingly. The comb handles are formed in the manner that the ends, away from the shear heads, of the comb rods are bent and extend in the direction away from the shear handles. By means of the tissue breaking shear for preparing the human body stem cells, the work efficiency can be improved, and tissue broken pieces attached to the shear blades can be removed conveniently.
Description
technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to tissue crushing scissors for preparing human stem cells. Background technique [0002] Umbilical cord mesenchymal stem cells are collected from medical waste neonatal umbilical cords, and can be differentiated into fat, bone, cartilage, muscle, tendon, ligament, nerve, liver, myocardium, endothelium and other tissues under specific induction conditions in vivo or in vitro Cells are a type of stem cells with high application value. A large number of umbilical cord mesenchymal stem cells exist in Wharton's jelly (Wharton's jelly) of the umbilical cord, so the existing preparation of umbilical cord mesenchymal stem cells is usually to cut the Wharton's jelly tissue in the umbilical cord into small pieces and follow the enzyme digestion method Alternatively, the adherent culture method is used for processing, and finally the umbilical cord mesenchymal stem cel...
