Problems solved by technology

[0003] However, such surgical treatment requires general anesthesia, and thus is highly invasive to the patient and expensive to treat
In addition, in LOD, there is a risk that the ovarian function will decrease due to the death of many follicles due to laser irradiation of the ovarian cortex

Embodiment

[0059] use Figure 1 to Figure 6 The follicle development inducing device according to the first embodiment of the present invention will be described in detail. figure 1 It is a plan view showing the state of use of the follicle growth inducing device according to the example. figure 2 It is a structural diagram of the follicle development inducing device related to the embodiment.

[0060] Such as figure 1 As shown, the follicle development inducing device 1 according to the embodiment includes: an ovarian puncture needle 2 for inducing the development of a follicle 50, along with ultrasonic waves emitted from a probe 52 of a transvaginal ultrasonic device (not shown) to an ovary 51. The traveling direction (arrow α in the figure) punctures the ovary 51 to form a puncture hole 53; and the optical fiber 8 guides the laser light emitted from the laser generator (not shown). In addition, as laser light, for example, laser light in the near-infrared region having a wavelengt...

Abstract

Provided is a follicular development inducing apparatus that is suitable for executing surgical therapy that is for the purpose of achieving follicular development induction and with which it is possible to reduce invasiveness and the risk of ovarian function deterioration. The follicular development inducing apparatus according to the present invention includes, in order to induce follicular development, an ovary piercing needle that forms a pierced hole in an ovary by piercing the ovary along a traveling direction of an ultrasonic wave emitted toward the ovary from a probe of a transvaginalultrasonic apparatus; and an optical fiber that guides laser light emitted from a laser generator. The ovary piercing needle is constituted of a needle tube formed of a base end, a body supported by the base end, and a needle tip that is connected to the body and that pierces the ovary, and the optical fiber is placed inside the needle tube so that a distal end thereof is positioned in the vicinity of the needle tip.

Description

technical field [0001] The invention relates to a follicle development inducing device for inducing follicle development, in particular to a follicle development inducing device equipped with an ovarian puncture needle for puncturing the ovarian cortex to apply physical stimulation to the ovary and an optical fiber placed inside the ovarian puncture needle. Background technique [0002] Conventionally, one of the causes of female infertility is, for example, polycystic ovary syndrome (PCOS: Polycystic ovarian syndrome). This PCOS is a disease in which although a large number of follicles are found in the ovary, they have stopped developing, and it is difficult to ovulate because the ovary itself is enlarged and covered with a thick white membrane. As one of its therapeutic methods, surgical therapy in which follicle development is induced by physically stimulating the ovary under laparoscopy or laparotomy has been performed. Specifically, wedge resection (Wedge resection) i...
