Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
A surgical device in combination with an endoscope, for stapling and fastening body tissues, said device comprising: holding means for holding a cassette containing a plurality of stapling/fastening members; applying means located in said holding means, for applying the stapling/fastening members to the body tissues; deforming means located in the vicinity of said holding means, for deforming the stapling/fastening members applied by said applying means, thereby fixing the stapling/fastening members to the body tissues; an insertion section having a proximal end portion and a distal end portion to which said holding means is connected, said insertion section being inserted into a channel of the endoscope; and an operation section removably connected to the proximal end portion of said insertion section after said insertion section is inserted into the channel of the endoscope, for operating said deforming means; an observation means located on a distal end of said endoscope; wherein said holding means is introduced into a body cavity by using the endoscope in order to staple the body tissues together.
