Detailed Description
The present invention proposes a sample transfer apparatus comprising: a handle unit 10, a tool unit 20.
The handle unit 10 includes a grip portion 13 and a connecting rod 14; a connecting rod 14 is formed at the upper end of the grip portion 13. The grip portion 13 may be formed thicker and the surface is formed into a rough surface, increasing the convenience of operation. The connection rod 13 may be formed in a thin sheet and have a certain elasticity.
The tool unit 20 comprises cross-set holders, each end of which is formed with a working head. The tool unit 20 may be formed in various forms, not limited to the cross shape in the drawings, but may be Y-shaped, rice-shaped, etc. The working head can be a tip part, a hook part, a plate part or a spoon part, and is applicable to tissue specimens in different situations.
The tool unit 20 is provided at an upper end of the connection rod of the handle unit 10.
As shown in fig. 2, the tool unit 20 includes a cross-shaped holder, the working heads of the four ends of which are a tip portion, a hook portion, a plate portion, and a spoon portion, respectively.
The tool unit 20 is coupled with the handle unit 10 by the coupling unit 0.
The combining unit 30 comprises a body, wherein a cross-shaped groove 31 is formed on the first side of the body, and a cross-shaped bracket is fixed in the cross-shaped groove 31; a square boss 33 is formed on the second side of the body, a guide rod 34 is formed on the boss 33, and a tip 35 is formed at the end of the guide rod 34. The center portion of the cross-shaped slot 31 may also form a recess 32, the recess 32 being adapted to receive the end of the pivot shaft of the center of the cross-shaped bracket.
