Endoscopic cutting forceps with jaw clamp lever latching mechanism
A lever latching system comprising: a housing; a lever having a latch pin fixedly mounted to the lever, the lever being movably mounted to the housing so that the latch pin moves in an arc; and a latch plate movably mounted to the housing for linear movement with respect to the housing, the latch plate comprising a labyrinth for receiving the latch pin.
1. A latching system comprising:
a first unit;
a second unit comprising a latch pin, said second unit being movably mounted to said first unit so that said latch pin moves in a prescribed motion;
a selector plate movably mounted to said first unit; and
a latch plate comprising a labyrinth for selectively receiving said latch pin, said latch plate being movably mounted to said selector plate;
wherein said latch plate moves linearly relative to said selector plate; and
wherein said prescribed motion is linear motion.
2. A latching system comprising:
a first member;
a second member comprising a latch pin, said second member being movably mounted to said first member so that said latch pin moves in a prescribed motion;
a selector plate movably mounted to said first member;
a latch plate movably mounted to said selector plate and comprising a labyrinth for selectively receiving said latch pin;
a spring secured to said selector plate and engaging said latch plate for biasing said latch plate with respect to said selector plate;
wherein said selector plate moves said latch plate between an engaged position wherein said labyrinth intersects said prescribed motion and a disengaged position wherein said labyrinth does not intersect said prescribed motion; and
wherein said prescribed motion is linear motion.
3. A latching system comprising:
a first unit;
a second unit comprising a latch pin, said second unit being movably mounted to said first unit so that said latch pin moves in a prescribed motion;
a selector plate movably mounted to said first unit; and
a latch plate comprising a labyrinth for selectively receiving said latch pin, said latch plate being movably mounted to said selector plate;
wherein said latch plate comprises an integral spring for biasing said latch plate relative to said selector plate; and
wherein said prescribed motion is linear motion.
