Abstract

Abstract Described is a grip part of an endoscopic instrument with at least a movable control element for mechanical guidance of a tool unit mounted on the distal end of the shaft of the endoscopic instrument and a main body. The invention is distinguished in that the main body has a largely symmetrical shape which is ergonomically adapted to the human hand such that the endoscopic instrument can be encircled at least partially by the palm of a hand balled into a fist and that the operating element is movable relative to the main body.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 122 words
A grip for use with a surgical instrument, comprising: an extension having a distal end and a proximal end, said distal end being connectable to a shaft of a surgical instrument; a main body having a symmetrical shape and being adjustably attached to said proximal end of said extension; a rotation device located between and adapted to be in contact with both the shaft and said distal end of the extension, said rotation device for rotating the shaft about its axis; a finger supporting device fixed to said extension and located between said rotation device and said main body for facilitating actuation of the surgical instrument; and a control element pivotably attached to said finger supporting device for actuating the surgical instrument.
Claim 2
Dependent Claim 122 words
A grip for use with a surgical instrument, comprising: an extension having a distal end and a proximal end, said distal end being connectable to a shaft of a surgical instrument; a main body having a symmetrical shape and being adjustably attached to said proximal end of said extension; a rotation device located between and adapted to be in contact with both the shaft and said distal end of the extension, said rotation device for rotating the shaft about its axis; a finger supporting device fixed to said extension and located between said rotation device and said main body for facilitating actuation of the surgical instrument; and a control element pivotably attached to said finger supporting device for actuating the surgical instrument.
