Abstract
The utility model relates to a microinjection pipe belongs to procreation medical science micromanipulation instrument technical field in vitro fertilization. It comprises tub pole and tube head, and the pipe pole is hollow structure, and the lower extreme of pipe pole is hollow cone structure, and hollow cone structure's lower part preparation has the tube head, and the inner wall of tube head is oval inner wall, and the outer wall of tube head comprises oval outer wall and tip, and the tip is located the lower part of oval outer wall, the minor axis diameter D1 of oval inner wall be 4.5~5.5 microns, the minor axis diameter D2 of oval outer wall is 6~7 microns, the inclined plane angle of tube head is 28~34 degrees, the bending angle of pipe pole is 20~35 degrees. The utility model discloses have unique toper shape, once can carry a plurality of sperms and be used for injecting the female born of the same parents of a plurality of ovum. Its tip is short and sharp keen, the accurate no traumatism of being convenient for ground puncture egg cell, tube head shape and internal diameter size to fit, accurate internal diameter just in time supplies a sperm to pass through when using, and the success rate of microinjection technique is high. And the preparation is simple, convenient operation, steady quality.
Description
Technical field
This utility model relates to a kind of microinjection pipe, belongs to reproductive medicine external fertilization micrurgy technical field of tools.
Background technology
In recent years, along with going deep into of human reproduction's basic medical theoretical research and developing rapidly of new technique, adopt microscopic insemination method to carry out treatment some difficult and complicated illness in infertility such as oligospermia, azoospermia, teratospermia disease, part azoospermia etc. and achieve gratifying effect. This method can select eupyrene sperm form, then completes Process of Insemination in sperm injection to oocyte, so as to have far reaching significance in hereditism, eugenics, reproduction control etc. In the operating process of microscopic insemination, the quality of its operation instrument especially syringe, shape and internal diameter are the key factors affecting embryo quality, directly affect the success or failure of microinjection technique. Therefore. developing high-quality syringe is the key smoothly completing microscopic insemination technology.
Summary of the invention
The purpose of this utility model is in that, it is provided that one has unique taper shape, and internal diameter size is suitable, and tip length is reasonable, and preparation is simple, easy to operate, stay-in-grade microinjection pipe.
This utility model is to realize above-mentioned purpose by the following technical solutions:
This microinjection pipe is made up of tube rod and tube head, it is characterized in that: tube rod is hollow-core construction, the lower end of tube rod is hollow cone structure, the bottom of hollow cone structure makes tube head, the inwall of tube head is oval inwall, the outer wall of tube head is made up of oval outer wall and tip, and tip is positioned at the bottom of oval outer wall; The minor axis diameter D1 of described oval inwall is 4.5��5.5 microns, and the minor axis diameter D2 of oval outer wall is 6��7 microns, and the bevel angle of tube head is 28��34 degree; Described tube rod bends to tube head direction, and the angle of bend of tube rod is 20��35 degree.
This utility model having the beneficial effects that compared with prior art:
This microinjection pipe has the conical by its shape of uniqueness, is conducive to the easy motion of inclusions, once can carry multiple sperm in order to inject multiple oocyte.Its tip is short and sharp keen, it is simple to precisely puncture ovum without wound ground; Tube head shape and internal diameter size to fit, internal diameter just passes through for a sperm in use accurately, and the success rate of microinjection technique is high. And preparation is simple, easy to operate, steady quality, shape is reasonable.
