Definitions
- the invention relates to a grip part of an endoscopic instrument with at least one movable operating element for the menian control of a tool unit attached to the distal shaft end of the endoscopic instrument, and a base body.
- scissor handles for example, have long been known which, by actuation, permit the opening and closing of pliers tools attached to endoscopic instruments on the distal side. If twisting of the pliers tools in the open or closed position is necessary on the distal side, the operator must twist the wrist accordingly in the case of such scissor-like handle parts. However, this is only possible up to a certain angle, which is determined by the maximum rotatability of the human wrist. Further rotation is possible by rotating the shaft using a knurled nut. Furthermore, branch handles and scissor handles cannot be individual hand size.
- the invention has for its object to provide a handle part of an endoscopic instrument with at least one movable control element for mechanical control of a tool unit attached to the distal shaft end of the endoscopic instrument and a basic body, so that the handle part is suitable for both left-handed and right-handed use is.
- the handle part is as simple as possible in terms of the spatial geometry, so that the associated manufacturing costs can be reduced.
- individual adjustment measures should be possible on the handle part in order to meet the different hand sizes of the surgeons.
- a handle part of an endoscopic instrument with at least one movable operating element for mechanical control of a tool unit attached to the distal shaft end of the endoscopic instrument and a base body are designed such that the base body has a largely symmetrical shape that is adapted to the ergonomics of the human hand in such a way that the endoscopic instrument solely over the base body, which can be at least partially enclosed by a palm shaped into a fist, is fixable, and that the control element is movable relative to the base body.
- the invention is based on the idea of designing the base body of the handle part as symmetrically as possible and of a size so that the base body can be held largely exclusively by a palm formed into a fist.
- Advantageous geometries of such basic bodies are spherical bodies, such as a sphere, or else elongated shapes, which preferably correspond to the width of the palm and which can be largely encompassed by this in the curved position.
- the symmetrical configuration of the base body according to the invention makes it possible for the surgeon to grip the grip part with both the left and right hand.
- the surgeon may have to operate several endoscopic instruments at the same time; It is of great advantage here if the surgeon can operate one and the same endoscopic instrument with both the left and the right hand in order to be able to carry out the operations more quickly, if necessary, and thus more gently for the patient.
- the base body is preferably attached in the proximal extension to the instrument axis and can be fixed displaceably relative to the operating element. In this way it is possible to individually adapt the handle part to the size of the surgeon's hand.
- a counterhold is attached to the base body in the distal direction, with which the surgeon can place at least one of his fingers to the counterhold.
- the control element is preferably movably attached to the counterhold.
- FIG. 1 is a schematic representation of a handle part for an endoscopic instrument
- Fig. 2 alternative embodiment for a base body.
- Fig. 1 is an endoscopic instrument with a
- a handle part 3 is arranged on the proximal side of the instrument shaft 1, with which it is possible to open and close the pliers-like tool unit and to twist it about the instrument shaft axis.
- the grip part 3 provides a base body 4 which is designed in the manner of a ball and which is formed both from the left and from the left right hand of the surgeon can be enclosed at least in such a way with the palm of the hand so that the entire endoscopic instrument can be carried by the base body 4.
- the base body 4 is attached on the proximal side to an extension 5 and can be displaced relative to the extension 5 and fixed to the extension 5 with a fixing unit 6, which can be designed, for example, in the manner of a grub screw.
- This displaceability makes it possible to adjust the base body 4 relative to the control element 7 in such a way that it is ergonomically convenient for an operator to operate the handle part 3.
- a holding web 10 is provided, on which at least one finger can be placed in order to increase the counter pressure of the base body 4 in the direction of the palm of an operator's hand, which is not shown in the drawing.
- the tool unit 2 can be opened and closed by moving the control element 7 relative to the base body 4.
- knurled screws 8 and 9 are provided with which, on the one hand, the tool unit 2 together with the instrument shaft 1 can be rotated about the shaft axis and, on the other hand, a firm connection of the instrument shaft with the handle part 3 can be established.
- FIG. 2 shows an alternative embodiment of a base body 4, which has a wedge shape in cross section and is ergonomically adapted to the human palm. With this shape it is also possible to hold the entire endoscopic instrument only by enclosing the grip part 4.
