Abstract
A medical stapler includes a grasping portion connected to an endoscope and having a first jaw and a second jaw connected by a rotation shaft; an operation portion configured to receive an external force for operating the grasping portion to open and close; a first wire configured to transmit the external force that is received by the operation portion to the grasping portion; and a movable pin attached to a distal end of the first wire, wherein the grasping portion is transitioned to an open state and a closed state by the first/second jaw relatively rotating with each other, and the movable pin is advanceable and retractable between positions at the proximal-end and distal-end side of the rotation shaft in a state in which the movable pin is engaged with an engagement groove formed in the first jaw.
Claims20
A medical stapler, comprising:
- a cap configured to attach to an endoscope;
- a grasping portion connected to the cap and having a first jaw and a second jaw connected by a rotation shaft;
- an operation portion configured to receive an external force for operating the grasping portion to open and close;
- a first wire including a proximal end connected with the operation portion and a distal end connected with the grasping portion;
- and
- a movable pin attached to the distal end of the first wire, wherein:
- the grasping portion is transitioned to an open state and a closed state by the first jaw and the second jaw relatively rotating around the rotation shaft;
- the rotation shaft is positioned more distally than a distal end of the cap;
- and
- the movable pin is advanceable and retractable between a position proximal relative to the rotation shaft and a position distal relative to the rotation shaft in a longitudinal direction of the first jaw in a state in which the movable pin is engaged with an engagement groove formed in the first jaw.
A medical system, comprising:
- an endoscope having flexibility;
- and
- a medical stapler engaged with the endoscope, wherein the medical stapler comprises:
- a cap configured to attach to the endoscope;
- a grasping portion connected to the cap, the grasping portion having a first jaw and a second jaw connected by a rotation shaft;
- an operation portion configured to receive an external force for operating the grasping portion to open and close;
- a first wire including a proximal end connected with the operation portion and a distal end connected with the grasping portion;
- and
- a movable pin attached to the distal end of the first wire, wherein;
- the grasping portion is transitioned to an open state and a closed state by the first jaw and the second jaw relatively rotating around the rotation shaft;
- the rotation shaft is positioned more distally a distal end of the cap;
- and
- the movable pin is advanceable and retractable between a position at a proximal-end side of the rotation shaft and a position at a distal-end side of the rotation shaft in a longitudinal direction of the first jaw in a state in which the movable pin is engaged with an engagement groove formed in the first jaw.
