Surgical device for stapling and/or fastening body tissues

A surgical device for stapling and fastening body tissues, comprising:

• an operation section operated outside a body cavity;
• an insertion section extending from said operation section for insertion into a body cavity;
• high-frequency applying means provided at a distal end portion of said insertion section for applying a high-frequency wave to body tissues within a body cavity;
• a cartridge provided at the distal end portion of the insertion section, said cartridge containing a plurality of staples, the staples each having at least two legs which are to be inserted into the body tissues;
• staple-applying means provided at the distal end portion of the insertion section, and coupled to said cartridge for applying at least one staple from said cartridge to target tissues through said distal end portion of said insertion section;
• staple-deforming means, including an anvil, provided at the distal end portion of the insertion section for deforming the at least one staple applied to the target tissues by said staple-applying means, thereby stapling the target tissues together;
• and
• current-supplying mean, extending through said insertion section from said operation section to said high-frequency frequency applying means, for supplying a high-frequency current to said high-frequency applying means to prevent bleeding of treated target tissues, said high-frequency applying means being electrically connected to the at least one staple applied to the target tissues and applying high-frequency waves to the at least one staple;
• said cartridge, said staple-applying means and said staple-deforming all means being operatable by operating said operation section;
• said anvil and said cartridge being rotatably connected to said distal end portion of said insertion section and have opposing surfaces between which target tissues are held;
• said staple-applying means applying the staples from said cartridge toward said anvil such that the legs of a staple pierce the target tissues;
• said anvil and said cartridge each having a proximal portion extending in a same direction as said insertion section, and a distal portion curving in a plane perpendicular to a direction of applying the staple;
• an electrically conductive cutter for cutting the target tissues, said cutter being provided at said distal end portion of said insertion section;
• said staple-deforming means and said cartridge being located near said high-frequency applying means in order to staple the target tissues to be cut by said cutting;
• and
• said high-frequency applying means includes means for applying a high-frequency wave to said cutter to prevent bleeding due to cutting of the target tissues.

• staple-deforming means provided at the distal end portion of the insertion section for deforming the at least one staple applied to the target tissues by said staple-applying means, thereby stapling the target tissues together;
• and
• current-supplying means, extending through said insertion section from said operation section to said high-frequency applying means, for supplying a high-frequency current to said high-frequency, applying means to prevent bleeding of treated target tissues;
• said cartridge, said staple-applying means and said staple-deforming all means being operatable by operating said operation section;
• and wherein:
• said distal end portion of said insertion section has an end face;
• said staple-applying means is formed in said end face and has a staple-applying opening;
• and
• said high-frequency applying means comprises a member projecting from said end face for supplying the high-frequency current to the target tissues when set in contact with the target tissues and for moving the target tissues in the direction of applying the staples.
