Abstract

The utility model relates to an oocyte microinjection puncture needle, belonging to the medical instruments in reproductive medicine field; the utility model mainly solves the technical problems in the puncture and evacuation of eggs. The utility model includes a needle tube and a needle head, the tail end of the needle head is provided with a tip, and a through hole on the needle head becomes tapering along the needle head. The puncture needle is provided with the unique needle head and tip, can easily penetrate eggs without wound, which is beneficial to the flow of the liquid substance in evacuation or fertilization, and facilitates the clear and comprehensive control of sperm in the operation of fertilization.

Description

Oocyte microinjection puncture needle
Technical field
This utility model relates to the apparatus of aspect, medical science reproduction field, is a kind of oocyte microinjection puncture needle, is mainly used in finding time or be subjected to aspects such as precision processing oocyte.
Background technology
In the reproduction field, often relate to relevant treatment,, cultivate to carry out various effective fertilizations and embryo as finding time and artificial fertilization etc. of ovum to oocyte.Finding time or during the artificial fertilization, must enter ovum inside, fertilization and fetal development after how the degree of treatment of this process will determine.Because ovum is less, puncture is than difficulty and go back the easy damaged ovum; Carry out in the ovum relevant liquid and extract when handling after puncture, the quality of the effect of finding time will determine fertilization and fetal development afterwards.Therefore, in the reproduction field, anxious to be solved to technical problems such as ovum puncture, finds time.
Summary of the invention
This utility model is to solve to provide a kind of oocyte microinjection puncture needle to existing technical problems such as ovum puncture, finds time.This puncture needle ovum that not only can accurately puncture when normal running can also carry out evacuation processes to ovum.
Oocyte microinjection puncture needle of the present utility model is formed by the canals of stilling one-shot forming, has the through hole of extraction, includes needle body, syringe needle, and the syringe needle tail end has needle point, and above-mentioned through hole attenuates with syringe needle gradually in needle section.
Because this puncture needle has unique syringe needle and needle point, can be easily, enter in the ovum to no wound, help finding time or the flowing of the time of fertilization liquid, be fertilized be convenient to when operating clear, control sperm all sidedly.
Description of drawings
Fig. 1 is the first embodiment sketch map of the present utility model;
Fig. 2 is the second embodiment sketch map of the present utility model;
Fig. 3 is that the P of Fig. 2 is to sketch map.
The specific embodiment
Referring to institute's drawings attached, oocyte microinjection puncture needle of the present utility model is formed by the canals of stilling one-shot forming, has the through hole of extraction, includes needle tubing 1, syringe needle 2, and syringe needle 2 tail ends have needle point 3, and above-mentioned through hole attenuates with syringe needle gradually in needle section.
Described needle point 3 and needle tubing 1 and syringe needle 2 be (see figure 1) in line.
Described needle point 3 skew needle axis certain angle a, be convenient to clear, control is extracted or the artificial fertilization all sidedly, this angle a is 0~45 degree, preferred 35 degree (see figure 2)s.
The inner diameter d 1 of above-mentioned needle tubing 1 is 0.70~0.80mm, helps flowing of liquid, and its outer diameter D 1 is 0.95~1.05mm, and its length L 1 is 47~70mm.
Above-mentioned syringe needle 2 length L 2 are 7~10mm, and wherein the length of needle point 3 is 80~120 μ m; Described needle point 3 has pin mouth and pointed section, helps piercing through ovum, and the internal diameter of this pin mouth is 4~6 μ m, and its external diameter is 5~7 μ m, and the length of this pointed section is 2.5~5.0 μ m.
