Abstract: Disclosed is a soluble suturing device for an intestine, which includes a suturing receptor, a staple receiver and a suturing presser, each of which is formed of a material to be solubilized by an intestinal juice and shaped in the form of a cylindrical body having an outer diameter insertable into an intestine. The suturing receptor, at its rear end, is provided with a suitable number of receiving seats located circumferentially therein each having a staple-receiving groove and formed of a rigod material, while the staple receiver, at its front end, abuts the rear end of the suturing receptor and is provided with a corresponding number of staple-holding apertures, each arranged for holding a staple at a position corresponding to the staple-receiving groove of the seat. The suturing presser is provided with a staple-urging plate for urging the staple in each of the staple-holding apertures toward the staple-receiving groove.

Abstract: The male tube at one end is provided with a connecting tubular piece adapted to fit into the female tube. The female tube in the connected position of the tubes is provided with a hole for inserting a pin in order to secure the connection of both tubes. The material for forming the tubes may be coated with a thin film of slowly water soluble polymeric material in order to allow a delayed dissolution of the tubes into the intestinal fluid.

Abstract: An apparatus of the invention comprises a cylindrical hollow supporting member having a nozzle tip and needle opposing seats, suturing members surrounding the needle opposing seats and having therein needle receiving spaces and pushing members for supplying needles, actuating bars for moving the suturing members, and an adjusting member for operating the actuating bars. The apparatus is useful for connecting a rectum upon removal of the diseased part thereof.
