  • Publication number: 20240075672
    Abstract: It is an object of the present invention to provide a novel production method which makes it possible to obtain a molded product containing a P3HB-based resin through an injection blow molding method and a technique for using such a method. The object is achieved by providing a method for producing a molded product containing a P3HB-based resin, the method including the steps of: (A) plasticizing a resin composition containing a P3HB-based resin; (B) subjecting the plasticized resin composition obtained in the step (A) to injection molding to obtain a preform; and (C) subjecting the preform obtained in the step (B) to blow molding to obtain a molded product.

  • Publication number: 20110238093
    Abstract: A ligating-apparatus includes a clip, an operating wire, an inner sheath member and an outer sheath member. The clip ligates a body tissue with arms. The operating wire pulls the clip. The inner sheath member encloses the operating wire to support a clip holding member. The outer sheath member advances and retreats while covering the inner sheath member. The outer sheath member changes the degree of opening of the arms by causing each arm to abut on an inner peripheral surface thereof. A pair of arms includes first arm portion and a second arm portion connected continuously to the first arm portion via a bending portion. When the bending portion abuts against an inner peripheral surface end portion of the outer sheath member, the second arm portion is arranged at an inner side in a direction of a radius from an inner peripheral surface of the outer sheath member.
