Abstract:
An insertion part 6 comprises a rigid member 62 having a surgical instrument insertion hole 11 through which a surgical instrument is inserted, and a standing base 13 which adjusts, by being rotated, the direction which a surgical instrument protrudes through the instrument insertion hole 11 to the tip side, and which is rotatably provided with respect to the rigid member 62, further towards the tip side than the surgical instrument insertion hole 11. A first guide groove 131 for holding a surgical instrument is formed on the outer surface of the standing base 13. At least part of the inner surface of the surgical instrument insertion hole 11 has an opening width that is smaller than the diameter of said surgical instrument insertion hole 11, and a second guide groove 113 that clamps the surgical instrument together with the first guide groove is formed.
