Problems solved by technology

[0005] However, this known construction has the disadvantage that on the one hand only a relatively small number of steering lines, ie only four steering lines, are used and on the other hand the space available as a drive for the steering lines can only be manually manipulated. Upper adjustable disc, whereby the pivoting links on the distal side can hardly be adjusted sensitively and reproducibly

Embodiment Construction

[0032] figure 1 A medical device 1 is shown schematically with a hollow shaft 2 , an actuation unit 4 arranged at the proximal end 3 of the shaft 2 , shown only schematically, and a belt arranged at the distal end 5 of the shaft 2 . There is an instrument end 6 of an instrument 7 , which can be actuated via an actuating element 8 mounted axially displaceably in the shaft 2 , which is operatively connected to the actuating unit 4 on the proximal side.

[0033] The actuation unit 4 can be a handle that can be actuated manually, or a structural unit that is designed for robotic applications, ie can be actuated without hands.

[0034] The instrument 7 at the instrument end 6 can be, for example, a knife provided with an open portion (as in figure 1 shown in ), or an endoscope, applicator, or the like.

[0035]The instrument tip 6 is pivotable relative to the longitudinal axis 10 of the shaft 2 by means of a hinge mechanism 9 consisting of a pivot link 11 arranged at the distal e...

Abstract

The invention relates to a medical instrument (1) having a hollow shaft (2), an actuation unit (4) arranged at a proximal end (3) of the shaft (2), and an instrument tip (6) with an instrument (7) arranged at a distal end (5) of the shaft (2); wherein the instrument (7) can be actuated by means of an actuating element (8) mounted axially displaceably in the shaft (2), which actuating element is operatively connected on the proximal side to the actuating unit (4) and the instrument end (6) can be pivoted relative to the longitudinal axis (10) of the shaft (2) by means of a hinge mechanism (9);wherein the hinge mechanism (9) is formed by a pivot link (11) arranged at the distal end (5) of the shaft (2), which pivot link is connected to the proximal drive (13) by means of a deflection line (12) extending in the longitudinal direction of the shaft (2), such that a movement of the proximal drive (13) causes a corresponding relative movement of the distal pivot link (11), thereby causing apivoting of the instrument tip (6), and wherein the proximal drive (13) has a spatially adjustable disk (14) on which the steering wire (12) is mounted. In order to achieve a medical device (1) of thetype mentioned above, in which any number of deflection lines (12) can be precisely and repeatedly actuated, it is provided according to the invention that the drive (13) for the spatially adjustabledisk (14) is a motor-driven drive (13).

Description

technical field [0001] The invention relates to a medical instrument with a hollow shaft, an actuating unit arranged at the proximal end of the shaft and an instrument end with an instrument arranged at the distal end of the shaft, wherein the The instrument is actuated by an actuating element in the shaft, which is operatively connected to the actuating unit on the proximal side and the end of the instrument can be pivoted relative to the longitudinal axis of the shaft via a hinge mechanism, wherein the hinge mechanism is arranged by A pivoting link at the distal end of the shaft is formed, which is connected to the driver on the proximal side via a steering line extending in the longitudinal direction of the shaft, so that the movement of the driver on the proximal side causes the movement of the distal end. The corresponding relative movement of the side pivoting links in turn causes the pivoting of the instrument end, and wherein the driver on the proximal side has a spati...
