Apparatus for compressing body tissue
A medical device for endoscopically deploying a hemostatic clip adapted to compress tissue. The hemostatic clip comprises a ring portion adapted to fit on a distal end of an endoscope and a plurality of legs attached to the ring portion, each of the legs being movable between an open position and a closed position to compress tissue. The device may include an actuator mechanism to move each of the legs from the open position to the closed position. The device may include a releasable attachment connecting the clip to the endoscope. The clip may include a hinge connecting the ring portion to each of the legs.
1. A medical device for endoscopically deploying a hemostatic multi-legged clip adapted to compress tissue, comprising:
an endoscope;
a hemostatic multi-legged clip comprising a ring portion adapted to fit around a distal end of the endoscope and a plurality of legs attached to the ring portion, each of the legs being movable between an open position and a closed position to compress tissue; and
an actuator mechanism operable by a user to move the legs between the open and closed positions, wherein the actuator mechanism comprises strings pulling each of the legs in the closed position.
2. A medical device for endoscopically deploying a hemostatic multi-legged clip adapted to compress tissue, comprising:
an endoscope;
a hemostatic multi-legged clip comprising a ring portion adapted to fit around a distal end of the endoscope and a plurality of legs attached to the ring portion, each of the legs being movable between an open position and a closed position to compress tissue; and
an actuator mechanism operable by a user to move the legs between the open and closed positions, wherein the actuator mechanism comprises a hydraulic piston exerting a force on each of the legs.
3. A medical device for endoscopically deploying a hemostatic multi-legged clip adapted to compress tissue, comprising:
an endoscope; and
a hemostatic multi-legged clip comprising a ring portion releasably mounted around a distal end of the endoscope and a plurality of legs attached to the ring portion, each of the legs being movable between an open position and a closed position to compress tissue, wherein the hemostatic multi-legged clip is releasably mounted around the endoscope via a releasable attachment comprising a thread forming a stitch between the hemostatic multi-legged clip and the endoscope.
4. A medical device for endoscopically deploying a hemostatic multi-legged clip adapted to compress tissue, comprising:
an endoscope; and
a hemostatic multi-legged clip comprising a ring portion releasably mounted around a distal end of the endoscope and a plurality of legs attached to the ring portion, each of the legs being movable between an open position and a closed position to compress tissue, wherein the hemostatic multi-legged clip is releasably mounted around the endoscope via a releasable attachment comprising a seal connecting the hemostatic multi-legged clip to the endoscope, and a thread embedded in the seal, such that removal of the thread cuts the seal.
5. A medical device for endoscopically deploying a hemostatic multi-legged clip adapted to compress tissue, comprising:
an endoscope; and
a hemostatic multi-legged clip comprising a ring portion releasably mounted around a distal end of the endoscope and a plurality of legs attached to the ring portion, each of the legs being movable between an open position and a closed position to compress tissue, wherein the hemostatic multi-legged clip is releasably mounted around the endoscope via a releasable attachment comprising a protrusion extending from one of the hemostatic multi-legged clip and the endoscope and a complementary groove formed in the other of the hemostatic multi-legged clip and the endoscope, wherein the protrusion and the groove are connected frictionally.
6. A medical device for endoscopically deploying a hemostatic multi-legged clip adapted to compress tissue, comprising:
an endoscope; and
a hemostatic multi-legged clip comprising a ring portion releasably mounted around a distal end of the endoscope and a plurality of legs attached to the ring portion, each of the legs being movable between an open position and a closed position to compress tissue, wherein the hemostatic multi-legged clip is releasably mounted around the endoscope via a releasable attachment comprising a catch extending from one of the hemostatic multi-legged clip and the endoscope, a complementary slot formed in the other of the hemostatic multi-legged clip and the endoscope, and an actuator for releasing the catch from the groove to release the hemostatic multi-legged clip.
