The following describes the embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1-4, the utility model discloses a medical material-drawing folding knife, comprising:
the tool comprises a tool handle 1, wherein a containing groove 11 is formed in the lower part of the tool handle 1;
the first blade 21 is fixed at the front end of the cutter handle 1;
the second blade 22 is hinged to the front end of the handle 1, when the second blade 22 is unfolded, the second blade 22 and the first blade 21 are arranged side by side in parallel at intervals, the distance between the second blade 22 and the first blade 21 is 0.2-0.3 cm, and when the second blade 22 is stored, the second blade 22 is located in the containing groove 11;
and the positioning sleeve 3 is clamped on the knife backs of the first blade 21 and the second blade 22.
As shown in fig. 4, the cross section of the positioning sleeve 3 is m-shaped, two positioning grooves 31 which are parallel to each other are arranged in the positioning sleeve 3, and the positioning grooves 31 of the positioning sleeve 3 are respectively connected with the knife backs of the first blade 21 and the second blade 22 in a clamping manner. Due to the reinforcing effect of the positioning sleeve 3 on the first blade 21 and the second blade 22, the phenomenon that the front ends of the two parallel blades are separated in the cutting process is avoided, and the uniform material drawing thickness is ensured. The compression of the tissue can be reduced. Save the time of drawing materials and obviously improve the speed and quality of drawing materials.
The outer side of the knife handle 1 is provided with an antiskid bulge 12. Increase the frictional force of holding handle of a knife 1 when drawing materials, prevent the slippage of handle of a knife 1 in the process of drawing materials.
