Abstract: The present invention relates to an automatic tension measurer, comprising: a band lengthily formed in a longitudinal direction; a main body formed to allow the band to be guided thereinto such that one-side end portion of the band is fixed and the other-side end portion thereof is drawn to the outside; a marking part implemented in the main body, and formed so as to enable marking in the band at a specific position in response to the tension applied to the band; and a stopper formed in the main body, and stopping the band at a specific position.

Abstract: A band tightening apparatus for binding an intestine with a band according to an embodiment of the present disclosure pulls a holder that fixes a band so that the length of the band wound around the intestine is ideally adjusted. The apparatus can pull the band wound around the intestine so that the length of the band wound around the intestine is ideally adjusted and the apparatus can fix the band with a fixing pin for convenient use.

Abstract: An apparatus for fixing an instrument within the intestinal canal, according to the present invention, is a fixing apparatus for surrounding, from outside the intestinal canal, and fixing an instrument that is installed within the intestinal canal for protecting an anastomotic site after a resection surgery of a tube-type organ, characterized in that the apparatus for fixing an instrument within the intestinal canal has a band-shaped body having predetermined thickness and width, wherein the body is formed of a biodegradable (absorbent) material or a non-absorbent material, which does not react with foreign bodies in the human body, wherein the body has a low elongation rate in the length direction thereof, and wherein both edges of the body in the width direction thereof are processed so as to have a flexible form so that when the edges come in contact with an outer surface of the intestinal canal, injuries are not made to the outer surface of the intestinal canal.
