Abstract
A hand-held sliding shaft-type surgical instrument includes a shaft, in which a longitudinal groove is formed extending over the length of the shaft, and a slide, which is movably mounted in the longitudinal groove. Relative movement of the slide in the longitudinal groove is at least partly guided by at least one connecting piece that constricts the longitudinal groove in the width direction. The shaft has a cleaning recess in the region of the connecting piece in the longitudinal direction. The cleaning recess forms a radial through-opening that opens into the longitudinal groove from the groove base side.
Claims14
A hand-held surgical instrument comprising:
- an elongated shaft having a longitudinal groove extending along the elongated shaft along a length direction, a width direction transverse to the length direction, and a depth direction transverse to the length direction and the width direction, wherein the longitudinal groove extends in the depth direction from a first side of the elongated shaft to a groove ground located between the first side of the elongated shaft and a second side of the elongated shaft, the second side being opposite the first side;
- and
- a slide, which is mounted displaceably in the longitudinal groove,
- displacement of the slide in the longitudinal groove along the length direction being guided in sections by at least one crosspiece of the elongated shaft that narrows the longitudinal groove in the width direction,
- the elongated shaft comprising, in a region of the at least one crosspiece, a cleaning recess comprising a radial through hole that extends in the depth direction to form an open passage from the groove ground to the second side of the elongated shaft
- wherein a longitudinal dimension of the at least one crosspiece along the length direction increases in the depth direction from the first side of the elongated shaft to the groove ground, and
- wherein the at least one crosspiece extends in the depth direction from the first side of the elongated shaft to the groove ground.
