Novel test-tube baby ovum-peeling manipulator

Abstract

The invention relates to a novel test-tube baby ovum-peeling manipulator, and belongs to the field of manufacturing technology of an ovum peeling device. The novel test-tube baby ovum-peeling manipulator is composed of a handheld press device and an ovocyte sucking device, wherein the handheld press device is composed of a press rod cap, a pen cap, a rear shell, a spring, a press rod and a front shell, and the ovocyte sucking device is composed of an airbag, a poly styrene (PS) tube, a needle seat and an ovum peeling tube. The airbag, the PS tube, the needle seat and the ovum peeling tube are successively installed on the lower-middle portion of the rear shell from top to bottom, and a push button connected with a slide fastener is installed in the middle of the front shell. According to the novel test-tube baby ovum-peeling manipulator, the PS tube of the ovocyte sucking device is fixed inside grooves inside the front shell and the rear shell, the airbag is pressed to produce balanced sucking force during a using process, and other portions do not move. The novel test-tube baby ovum-peeling manipulator resolves the problem that granule cells on the periphery of an ovocyte cannot be sucked accurately or an embryo or the ovocyte cannot be transferred accurately through an existing test-tube baby ovum-peeling manipulator.

Description

technical field [0001] The invention relates to an egg stripping manipulator, in particular to a novel test tube baby egg stripping manipulator suitable for removing granulosa cells around oocytes or transferring embryos and oocytes. Background technique [0002] Due to its structure, the existing test-tube baby stripping operator has the following defects during use: [0003] 1. During the egg peeling operation, press the rubber straw button, because the shell does not fix the egg peeling tube, there will be a rubber straw connected to drive the egg peeling tube, and the granulosa cells around the oocyte cannot be accurately sucked Or transfer embryos and oocytes. [0004] 2. During the egg peeling operation, because the outer diameter of the shell of the egg peeling manipulator is too thin and the length is too short, the operator's hand is very close to the head of the pipette, which is inconvenient for the operator to hold, and it is prone to displacement during use.

AI Technical Summary

Problems solved by technology

[0003] 1. During the egg peeling operation, press the rubber straw button, because the shell does not fix the egg peeling tube, there will be a rubber straw connected to drive the egg peeling tube, and the granulosa cells around the oocyte cannot be accurately sucked or transfer of embryos and oocytes

[0004] 2. During the egg peeling operation, because the outer diameter of the shell of the egg peeling manipulator is too thin and the length is too short, the operator's hand is very close to the head of the pipette, which is inconvenient for the operator to hold, and it is prone to displacement during use. It is not very accurate to absorb granulosa cells around oocytes or transfer embryos and oocytes

[0005] 3. Because the suction head of the IVF egg peeling manipulator is small and the suction is small, it is not easy to clean the granule cells in a short time

[0006] 4. Some of the existing egg stripping manipulators are directly connected to the egg stripping tube, but they cannot be sterilized, causing oocytes and culture medium to be polluted during use
