VAGINAL WALL INCISION INSTRUMENT

摘要

A vaginal wall incision instrument includes a main body portion that is capable of being inserted into a vaginal canal; an incision portion that protrudes from a distal portion of the main body portion in a direction intersecting a center line of the vaginal canal and is formed by a conductive material; and an operating portion, wherein the main body portion includes an exterior portion and an interior portion, wherein the interior portion includes a contact portion, wherein a guide hole is configured on the interior portion, wherein the guide hole is capable of guiding the conductive member in a direction toward a boundary between the uterine cervix and the vaginal canal, and wherein the incision portion separates the vaginal canal along a circumference whose center is the center line of rotation by rotating the interior portion about the center line of rotation with respect to the exterior portion.

1. A vaginal wall incision instrument, comprising:
a main body portion that is capable of being inserted into a vaginal canal; an incision portion that protrudes from a distal portion of the main body portion in a direction intersecting a center line of the vaginal canal and is capable of penetrating through the vaginal canal while the main body portion is inserted into the vaginal canal, the incision portion being formed by a conductive material; and an operating portion that is disposed at a proximal part of the main body portion to be capable of adjusting an amount of protrusion of the incision portion, wherein the main body portion includes:
an exterior portion that is capable of contacting on an inner wall of the vaginal canal; andan interior portion that is inserted into the exterior portion and is capable of rotating about a predetermined center line of rotation with respect to the exterior portion, the interior portion having a distal portion to which the incision portion is fixed, wherein the interior portion includes a contact portion having a surface that is contactable on an uterine cervix; wherein a guide hole configured to guide a distal end portion of the conductive member such that the distal end portion of the conductive member is capable of being advanced and retracted in a direction intersecting the center line of the vaginal canal, wherein the guide hole being capable of guiding the conductive member in a direction toward a boundary between the uterine cervix and the vaginal canal while the contact portion is in contact with the uterine cervix, and wherein the incision portion separates the vaginal canal along a circumference whose center is the center line of rotation by rotating the interior portion about the center line of rotation with respect to the exterior portion, in a state where the incision portion penetrates through the vaginal canal.
