Abstract

The utility model relates to an embryo transfer device, comprising a tube core bushing fixedly connected to a tubular joint in the tail and an embryo transfer tube sheathed in the tube core bushing. The tube core bushing is a toughness tube core bushing. An annular nonius which is able to move along the cylinder of the tube core bushing for orientation is arranged on the outside cylinder of the tube core bushing. The head of the tube core bushing is a gradually dwindling guide head. A plug is arranged on the exit-end of the embryo transfer tube. The external diameter of the small head end of the plug matches with the internal diameter of the embryo transfer tube, and the external diameter of the large head end matches with the internal diameter of the head end of the tube core bushing. The outside cylinder of the tail end of the embryo transfer tube is provided with a graduated scale. The utility model can replace present various embryo transfer devices for using.

Description

The simple type embryo transplanter

This utility model relates to a kind of medical apparatus.What be particularly related to is the embryo transplanter that a kind of test-tube baby is used.

In infertility treatment of diseases means, test-tube baby is one of common effective means.At present the embryo transplanter that uses in the test-tube baby operation is made of tube core cover, the tube core and the embryo transfer pipe that are sleeved in the tube core cover.Earlier tube core is sleeved in the tube core cover during use, and the tube core head end is stretched out slightly at tube core cover head end a bit constitute one " accurate closed " head end, the tube core cover that tube core will be housed is then sent in the patient uterus, utilizes its " accurate closed " head end to prevent that uterus mucus from entering tube core.And then with tube core taking-up from tube core overlaps, the tube core cover still keeps stretching in the uterus, and the embryo transfer pipe that the embryo will be housed again overlaps insertion and puts in the uterus through tube core, thereby reach embryo transfer is advanced in the cavity of uterus.The shortcoming one of this embryo transplanter is that its tube core cover uses not nimble, being difficult to successfully pass cervical canal stretches and reaches in the cavity of uterus, particularly those are suffered from the odd-shaped patient of cervical canal, send into cavity of uterus in just more difficult by odd-shaped cervical canal the tube core cover.The 2nd, its tube core only works to prevent that uterus mucus from entering the tube core cover, must take out to allow the embryo transfer pipe that the embryo is housed put in cavity of uterus from the tube core cover after covering into cavity of uterus with tube core, and operating procedure is many, time-consuming length.

The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, for the test-tube baby operation provides a kind of various uterus kenel situation that can be applicable to the embryo is implanted into intrauterine and the more easy simple type embryo transplanter of operation smoothly.

Realize the simple type embryo transplanter of this utility model purpose, comprise that its afterbody is connected with the tube core cover of a tubular configured joint and is sleeved on embryo transfer pipe in the tube core cover, described tube core cover is a toughness tube core cover, on the outer cylinder of tube core cover, be equipped with one and can overlap the annular vernier of cylinder running fix along tube core, the head end of tube core cover is a diminishing guiding head end, the port of export of described embryo transfer pipe is provided with a plug, the external diameter of the little head end of this plug matches with the internal diameter of embryo transfer pipe, the external diameter of stub end matches with the internal diameter of tube core cover head end, is provided with graduated scale on the outer cylinder of embryo transfer pipe tail end.During use with in the embryo transfer pipe insertion tube core retainer plate, and utilize the graduated scale on the outer cylinder of embryo transfer pipe tail end that the plug of its head end is placed in the head end of tube core cover, make the head end of tube core cover form " the close shape of an accurate envelope " head end, uterus mucus enters the tube core cover when preventing operation.The annular vernier is preset on a certain appropriate location of tube core cover to grasp the insertion depth of tube core cover, makes it to stretch the appropriate position that reaches cavity of uterus.The tubular configured joint of hand-held tube core cover tail end, flexible tube core cover transvaginal is stretched toward cervical orifice, utilize the toughness of its guiding head end and tube core cover body itself, make it can be in cervical canal at random comprehensive seeking, up to visiting internal cervical orifice and entering cavity of uterus.Back taking-up embryo transfer pipe puts in place, the plug of its port of export is extracted the back suck the embryo, the embryo transfer pipe that the embryo will be housed is again sent into the uterus in the tube core cover, utilize the graduated scale of embryo transfer pipe tail end setting to make the port of export of embryo transfer pipe stretch out correct position outside tube core cover head end, outer end at the embryo transfer pipe then can make the embryo in the pipe enter into cavity of uterus with the syringe injection pressure, thereby reach easily embryo transfer is advanced purpose in the cavity of uterus.

On the outer cylinder of tube core cover, graduated scale is set, can further accurately adjust the storing position of vernier according to different patients' uterus position, the insertion depth of tube core cover is grasped in a suitable position, when being convenient to seek, entering orificium internUm isthmi, also can be alleviated the person's of being awarded discomfort.

The utility model has the advantages that simple in structure, manufacture easily, compare with existing embryo transfer pipe and reduced tube core, saved material cost, made things convenient for use, shortened operating time, comfortableness is strong, the suitability is strong, success rate is high.Be particularly useful for lopsided cervical canal patient.Alternative existing various embryo transfer utensils use.

Provide embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1-6, the formation of this simple type embryo transplanter comprises that its afterbody is connected with the tube core cover 2 and the embryo transfer pipe 3 that is sleeved in the tube core cover 2 of a tubular configured joint 1, described tube core cover 3 is a toughness tube core cover, on the outer cylinder of tube core cover, be equipped with one and can overlap the annular vernier 4 of cylinder running fix along tube core, the head end 5 of tube core cover is a diminishing guiding head end, the port of export of described embryo transfer pipe is provided with a plug 7, the microcephaly of this plug 7 holds 6 external diameter to match with the internal diameter of embryo transfer pipe, the external diameter of stub end 9 matches with the internal diameter of tube core cover head end, is provided with graduated scale 8 on the outer cylinder of embryo transfer pipe tail end.Tube core cover 2 can be made of the toughness material of rubber-like, and the diameter of embryo transfer pipe is with slightly for a short time being advisable of diameter than tube core cover head end mouth.The external diameter of internal diameter and the tube core cover 2 of annular vernier 4 matches, and makes it to utilize the toughness of tube core cover to overlap cylinder along tube core and moves, can be positioned at again tube core and overlap on the cylinder.Roundlet rod 11 plugs that also available its diameter of plug matches with embryo's bore constitute (referring to Fig. 7) in a joint embryo pipe 12.

The degree of accuracy of graduated scale 10 with the storing position of raising vernier 4 also can be set on the outer cylinder of tube core cover.
