Abstract
The utility model discloses a unicellular microsurgical needle for protozoa and relates to a microsurgical needle. The unicellular microsurgical needle is used for solving the problem that the existing microsurgical instruments can not be used for carrying out unicellular microsurgeries through being matched with ordinary microscopes. The unicellular microsurgical needle disclosed by the utility model comprises a glass tube, a needle and a skidproof sleeve, wherein the glass tube is divided into a main body and a conical tube, the conical tube is located at one end of the glass tube, the length of the conical tube is 1-2 cm, the needle is fixedly connected with the thinnest end of the conical tube, the tube opening diameter of the thinnest end of the conical tube is 0.05-0.1 cm, and the skidproof sleeve is arranged at the outer side of the main body of the glass tube. The unicellular microsurgical needle disclosed by the utility model is thinner than general microsurgical instruments, can be used for carrying out unicellular dissection operation and is applied to the unicellular microsurgical operations of protozoa.
Description
Technical field
The utility model relates to a kind of micrurgy pin.
Background technology
Utilizing during unicellular protozoon carries out cytology research, often need to cut individual cells, splice, the nucleus picking, peel off, the experiment such as fusion, and be not fit to carry out the micro-surgical instruments of aforesaid operations all the time.The various micro-bistouries that medically use not only price are too expensive, and its size and structure can not satisfy the requirement of cytologic experiment, especially can't coordinate with simple microscope the operation of carrying out individual cells.
The utility model content
The utility model is will solve existing micro-surgical instruments can't coordinate the problem of carrying out unicellular micrurgy with simple microscope, provides a kind of protozoon unicellular micrurgy pin.
The unicellular micrurgy pin of the utility model protozoon comprises Glass tubing, pin and Anti-slip cover, described Glass tubing is divided into main body and conical tube, conical tube is positioned at an end of Glass tubing, the length of conical tube is 1～2cm, described pin is fixedly connected with the taper end of conical tube, the nozzle diameter of the taper end of conical tube is 0.05～0.1cm, and the main body outside of Glass tubing is provided with Anti-slip cover.
The utility model compared with prior art has following effect:
In cytologic experiment, the utility model can coordinate with ordinary optical microscope, carries out the single celled cutting of protozoon, splicing, and the nucleus picking, peel off, the microsurgical procedure such as fusion.Micrurgy pin of the present utility model is meticulousr than general micro-surgical instruments, can carry out unicellular dissection operation.
The utlity model has advantage practical, cheap, simple for production.
The utility model also can be used for the micrurgy experiment of various animal and plant cellss.
