PURPOSE:To simply change over the closure and opening of a body lumen by using a body lumen insert jig consisting of an insert jig main body formed into a tubular shape and a plurality of the plug jigs inserted and held in the insert jig main body in a freely detachable manner. CONSTITUTION:A hole 4 having an almost square shape is bored in the side surface part of one end of an insert jig main body 2 and plug jigs 3 having an almost spherical shape are inserted in the insert jig main body 2. At the time of sterility, incision having a length capable of inserting the insert jig main body is applied to the seminal canal A and the insert jig main body 2 in which a plurality of the plug jigs 3 are preliminarily inserted is inserted in the seminal canal A. Since the seminal canal A is closed by the plug jigs 3 inserted in the insert jig main body 2 in this state, the movement of the supermatozoa in the seminal canal A is blocked to obtain contraceptive effect. When generative function is desired to be returned if necessary, only the part of the hole 4 of the insert jig main body 2 of the seminal canal A is incided to take out the plug jigs 3. whereupon, the supermatozoa can pass, through the insert jig body 2 and generative function can be restored. |
