Endoscope forceps
First Claim
1. An endoscope forceps comprising;
- an operating section for inputting an operating force;
an insertion section fixedly connected to the operating section and adapted to be inserted into a channel of an endoscope;
an operating rod inserted in the insertion section so as to be movable forward or backward along a longitudinal direction of the insertion section, the operating rod having one end connected to the operating section for movement forward or backward in response to the operating force input from the operating section; and
a forceps section disposed at a fore end of the insertion section,wherein the forceps section comprises;
a first jaw pivotally mounted at another end of the operating rod through a first pivotal shaft engaging both the first jaw and the operating rod; and
a second jaw pivotally mounted at the fore end of the insertion section through a second pivotal shaft engaging both the second jaw and the insertion section;
wherein the first jaw and the second jaw are pivotally mounted to each other through a third pivotal shaft engaging both the first jaw and the second jaw.

Abstract
An endoscope forceps of the present invention comprises an operating section for inputting an operating force, an insertion section, which is fixedly connected to the operating section, and which can be inserted into a channel of an endoscope, an operating rod, which is inserted in the insertion section so as to be movable forward or backward, one end of which is connected to the operating section, and which is moved forward or backward by the operating force input to the operating section, and a forceps section which is disposed at the fore end of the insertion section, wherein the forceps section comprises a first jaw pivotably mounted at the other end of the operating rod with a first pivotal shaft engaging with both, and a second jaw pivotably mounted at the fore end of the inserting section with a second pivotal shaft engaging with both, and the first jaw and the second jaw are pivotably mounted to each other with a third pivotal shaft engaging with both.

11. An endoscope forceps comprising:
-
an operating section including a stationary handle and a movable handle pivotally connected to the stationary handle; an insertion section including a bracing member in the shape of a rod mounted to the stationary handle, an operating force transmitting member in the shape of a rod disposed in parallel to the bracing member and having one end detachably mounted to the movable handle, and a support member detachably mounted to both the bracing member and the operating force transmitting member and held therebetween, for supporting the parallel disposition of the bracing member and the operating force transmitting member; a forceps section disposed at a fore end of the insertion section; and positioning means for controlling a moving direction of the operating force transmitting member so that the operating force transmitting member moves only along an axial direction of the insertion section in response to operation of the movable handle, the operating force transmitting member being detachably mounted to the stationary handle by the positioning means, whereby the forceps section at the fore end of the insertion section is moved by forward or backward movement of the operating force transmitting member in response to operation of the movable handle. - View Dependent Claims (12)
