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

Embodiment Construction

[0019] The new test-tube baby peeling manipulator is composed of two parts: a hand-held pressing device and an oocyte suction device. The hand-held pressing device is composed of a pressure rod cap 1, a pen cap 2, a rear shell 3, a spring 4, a pressure rod 5 and a front shell 12; The device for absorbing oocytes is composed of an air bag 9, a PS tube 10, a needle holder 11 and an ovum stripping tube 13. The pressure rod 5 of the hand-held pressing device is installed in the upper end of the rear shell 3, and the top of the upper end of the rear shell 3 is equipped with a pen cap 2, and the pressure rod cap 1 socketed with the upper end of the pressure rod 5 is housed in the pen cap 2, and the pressure rod The bottom of 5 is equipped with a spring 4, and the middle part of the back shell 3 is movably linked with a front shell 12 by a hinge 8, and the back shell 3 and the front shell 4 can be opened or buckled together by the hinge 8; the middle part of the front shell 12 is equi...

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. C...
