    Abstract: Disclosed herein is a snare (transparent cap) for removing a polyp which includes a stalk and a head connected to the stalk, wherein the snare includes: a body having a hollow tubular shape and an interior of which is partitioned into a plurality of chambers; a ring mounted to at least part of the body using elasticity; a first snare discharged outside the body through a first chamber among the plurality of chambers and hooks the stalk; and a second snare which is discharged outside the body through a second chamber among the plurality of chambers, wherein when the stalk is spread according to pulling the first snare that hooks the stalk, and the second snare pulls a first portion in a lower end of the stalk as spread including the head, the ring is discharged from the body and shrinks through the elasticity and then fixes the first portion.

    Abstract: Provided is a technique of allowing a dental implant to be stably placed after extraction, to be accurately placed in a tooth extraction socket, and to be stably placed in the tooth extraction socket according to implantation position and angle. A method of manufacturing a scaffold for treatment of a tooth extraction socket and implantation of a dental implant includes receiving dental implantation information of dental CT data which is previously input via a terminal of a manager; manufacturing, by using a three-dimensional (3D) printer, a 3D model comprising alveolar bones and teeth, which are distinguished therebetween, based on a medical image file that is a medical image file (DICOM file) of the dental CT data; performing virtual tooth-extraction by removing, from the manufactured 3D model, a region corresponding to a tooth in a tooth-extraction target area; and manufacturing, by using the 3D printer, a scaffold to be placed in an actual tooth extraction socket according to a shape of a tooth extraction socket that exists in the manufactured 3D model as a result of the virtual tooth-extraction, wherein, when the scaffold is manufactured, image data of the scaffold is amended to allow a guide hole for implanting the dental implant to be formed in the scaffold based on the dental implantation information.
