| 摘要 | A medical instrument with a shank consisting of pivotable jaw parts and a handle, the two jaw parts of the tool are pivotable relative to each other independently via the handle and each of the pivotable jaw parts is actuated via a separate drive. One drive is designed as a grip part mounted pivotably on the handle and is connected to one jaw part via a first push/pull element mounted in an axially displaceable manner in the shank, and the other drive is an adjusting wheel rotatable about a longitudinal axis of the shank and is connected to the other jaw part of the tool via a second push/pull element mounted in an axially displaceable manner in the shank. The push/pull element is designed as a push/pull rod, and the push/pull element which is coupled to the adjusting wheel is designed as a push/pull tube coaxially surrounding the push/pull rod. | ||

| 主权项 | 1. A medical instrument comprising: a tool with two pivotable jaw parts arranged on the distal end of a shank and a handle arranged on the proximal end of the shank; wherein the two pivotable jaw parts of the tool can be pivoted relative to each other independently of each other via the handle and each of the two pivotable jaw parts can be actuated via a separate drive arranged on the handle; wherein one drive is designed as a grip part which is mounted pivotably on the handle and is operatively connected to one jaw part of the tool via a first push/pull element mounted in an axially displaceable manner in the shank; and another drive is designed as an adjusting wheel which is rotatable about a longitudinal axis of the shank and is operatively connected to the other jaw part of the tool via a second push/pull element mounted in an axially displaceable manner in the shank, characterized in that the first push/pull element which is coupled to the pivotable grip part is designed as an axially displaceable push/pull rod, and in that the second push/pull element which is coupled to the adjusting wheel is designed as an axially displaceable hollow push/pull tube coaxially surrounding the push/pull rod, wherein the push/pull rod is arranged inside the hollow push/pull tube. | ||
