Tissue stapling method and tissue stapler

Abstract

A position information transmitting member for transmitting position information to a staple receiving portion is provided in a tissue stapler having a staple receiving portion which comprises the anvil of the stapler. Thereby, an operator can easily locate the position of and grasp the staple receiving portion located within a tissue to swiftly execute stapling. The tissue stapler includes a stapling portion provided with an endoscope inserting tube path, a stapling portion provided with a staple injecting portion arranged on a distal end side of the inserting portion, and a staple receiving member (anvil) arranged separately from the inserting portion, to be grasped by a treatment tool introduced via the inserting portion in a state when it is opposed to the stapling portion via a tissue, to bend a distal end portion of a staple pressed out from the staple injecting portion of the stapling portion which has penetrated through the tissue.

1 . A tissue stapler comprising: 
 an inserting portion provided with an endoscope inserting tube path;    a stapling portion provided with a staple injecting portion arranged at a distal end of the inserting portion;    a staple receiving member arranged separately from the inserting portion and structured for being grasped by and fixed to a treatment tool introduced through the inserting portion in a state of being opposed to the stapling portion via a body tissue, the staple receiving member being formed to bend a distal end portion of a stapling staple member pressed out from the staple injecting portion of the stapling portion and penetrating through the tissue; and    a position information transmitting member provided at the staple receiving member for transmitting position information.    
     
     
         2 . The tissue stapler according to  claim 1 , further comprising: 
 a position detecting member for detecting a position of the staple receiving member by receiving the position information from the position information transmitting member; and    a guiding member for guiding the staple receiving member based on detected information of the position detecting member.    
     
     
         3 . The tissue stapler according to  claim 2 , wherein the position detecting member is arranged to be detected by at least one of an endoscope introduced via the inserting portion and the treatment tool, and wherein the guiding member comprises the treatment tool introduced via the inserting portion or the endoscope.  
     
     
         4 . The tissue stapler according to  claim 2 , wherein at least one of the position detecting member and the guiding member includes an endoscope and the treatment tool introduced transabdominally.  
     
     
         5 . The tissue stapler according to  claim 1 , wherein the staple receiving member is structured to be grasped by and fixed to the treatment portion using a magnetic force.  
     
     
         6 . The tissue stapler according to  claim 1 , wherein the stapling portion includes a cutting member for cutting an inner peripheral portion of the staple injecting portion.  
     
     
         7 . The tissue stapler according to  claim 1 , wherein the staple receiving member includes a main body thereof provided with a grasped portion having a diameter smaller than that of the stapling portion, a plurality of arm portions coupled with the main body and structured to be able to be folded in an inactivated state, and to expand when grasped at the grasped portion, to positions juxtaposed to the stapling portion.  
     
     
         8 . The tissue stapler according to  claim 1 , wherein the stapling portion is provided with a plurality of the staple injecting portions arranged in a substantially ring shape.  
     
     
         9 . A staple receiving member of a tissue stapler comprising: 
 a position information transmitting member for outputting electromagnetic waves for informing its position to another device.    
     
     
         10 . The staple receiving member according to a tissue stapler according to  claim 9 , wherein the position information transmitting member outputs light as the electromagnetic waves.  
     
     
         11 . The staple receiving member of a tissue stapler according to  claim 9 , further comprising: 
 a shaft member structured to be grasped by a treatment tool and including the position information transmitting member thereat.    
     
     
         12 . The tissue stapler according to  claim 1 , wherein the stapling portion comprises a grasping piece made of first and second pivotably arranged arms which are openable and closeable to grasp the staple receiving member.  
     
     
         13 . The tissue stapler according to  claim 1 , further comprising a rotating member for rotating a portion of the stapling portion relative to the staple receiving member.  
     
     
         14 . The tissue stapler according to  claim 1 , further comprising a suction arrangement for creating suction in an area between the stapling portion and the staple receiving member to draw the body tissue therebetween for being thereafter clamped and stapled.  
     
     
         15 . The tissue stapler according to  claim 1 , wherein the stapling portion comprises staples that are peripherally and spacedly arranged relative to one another and the staple members being oriented at an angle relative to the axial direction of the stapling portion.
