Problems solved by technology

[0005] At present, the commonly used ovarian transplantation technique is to put ovarian tissue slices (about 1.1-1.5mm) back into the patient’s body one by one with laparoscopic tissue forceps. Therefore, it is very time-consuming and takes about 2-4 hours, and the long exposure time of ovarian tissue slices in vitro will affect the effect of postoperative ovarian function recovery

Embodiment Construction

[0029] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0030] Such as Figure 1-5 As shown, a device for pushing ovarian tissue slices includes a pushing core 1 and an outer tube 2, the outer tube 2 is coaxially sleeved outside the pushing core 1, and the length of the pushing core 1 is greater than or equal to the length of the outer tube 2. To be precise, in this embodiment, a scale line 6 is provided along the axial direction of the outer tube 2, and the outer tube 2 is made of transparent material. The outer tube 2 is provided with a limit stopper 9 near the opening of one end of the handle 3, and a limit hole is opened in the center of the limit stopper 9, and the push core 1 passes through the limit hole, and the size of the limit hole is ...

Abstract

An ovarian tissue section pushing device comprises a pushing core and an outer tube, wherein the outer tube coaxially sleeves the outside of the pushing core; the length of the pushing core is greater than or equal to the length of the outer tube; one end of the pushing core is fixedly connected with a handle; a projection is arranged at the other end of the pushing core and is positioned in the outer tube; and the projection is in sliding fit with the outer tube in a sealed manner. The ovarian tissue section pushing device is simple in structure and convenient to use, and transplanting time of an ovarian tissue section is greatly saved; and because the exposure time of the ovarian tissue section out of the body is short, recovery of an ovarian tissue and fertility of a postoperative patient is facilitated.

Description

technical field [0001] The invention relates to the field of tissue transplantation instruments, in particular to an ovarian tissue slice pushing device. Background technique [0002] Premature ovarian failure refers to the failure of ovarian function in women before the age of 40. As a result, women of childbearing age lose their reproductive and endocrine functions, resulting in infertility and premature perimenopausal symptoms, with an incidence of about 1%. With the release of late marriage and late childbearing and the national two-child policy, the number of patients who are infertile due to premature ovarian failure has increased sharply. [0003] Studies have shown that ovarian tissue transplantation can restore the reproductive capacity and endocrine function of patients with premature ovarian failure. At present, ovarian tissue transplantation, which is widely used clinically, is mainly used for female patients with malignant tumors. Before the start of radiothera...
