Definitions
- the invention relates to a method for mounting and/or fastening steering elements on a spatially adjustable disk, wherein a distal-side joint mechanism for bending a distal end section of a medical instrument can be moved by means of the steering elements, and the spatially adjustable disk has a hole with a cross section for each steering element through a thickness of the spatially adjustable disk, at least partially has an internal cavity, an outer surface, an inner surface and a deflection contour for deflecting the steering wires.
- the invention further relates to steering elements for moving a distal-side joint mechanism for bending a distal end section of a medical instrument, a medical instrument and a robot.
- bendable instruments are often used, which can be designed as hand-held and/or robotic instruments.
- To bend the shaft of a medical instrument To enable this, four or more external steering wires and/or steering cables are usually arranged around pivot members of a distal joint mechanism.
- the use of a large number of thin steering wires is advantageous in order to enable uniform movement and force distribution in all bending directions.
- the steering wires must be fixed in a tensioned state on the distal side (far from the user) and proximal side (close to the user).
- each steering wire must first be pre-tensioned individually and then screwed to the swashplate. In addition to taking a lot of time, this can also lead to damage to the steering wires. Furthermore, the threaded holes on the swashplate and the corresponding screws, which are usually inserted and attached in and on the radially circumferential side wall of the swashplate, require a lot of installation space.
- the object of the invention is to improve the state of the art.
- the task is solved by a method for mounting and/or fastening steering elements on a spatially adjustable disk, wherein a distal-side joint mechanism for bending a distal end section of a medical instrument can be moved by means of the steering elements, and the spatially adjustable disk for each steering element Hole with a cross section through a thickness of the spatially adjustable disk, at least partially having an internal cavity, an outer surface, an inner surface and a deflection contour for deflecting the steering elements, with the following steps:
- This provides a method with which the steering elements are quickly and easily mounted on a spatially adjustable disk and the steering element ends passed through the spatially adjustable disk are fastened to the spatially adjustable disk by means of the at least one clamping element. It is particularly advantageous that the steering elements are connected in a tensioned state to the spatially adjustable disk in a force-fitting manner. Consequently, steering elements are provided which are optimally fixed to the spatially adjustable disk with a fixed, predetermined tension in the tensioned state. By clamping using the at least one clamping element, the steering elements are uniformly fastened and thus homogeneously prestressed. It is particularly advantageous that only one clamping element is necessary for this, so that all sections of the steering elements that are passed through can be clamped at the same time.
- a proximal drive movement on the spatially adjustable disk is optimally transmitted to the distal components of a distal joint mechanism for angling the distal end section of the medical instrument by means of the force-fitting and tensioned steering elements.
- the materials are: Connection partner freely selectable.
- the steering elements can therefore, for example, have a nickel-titanium alloy and the spatially adjustable disk can have a chrome-nickel-molybdenum stainless steel.
- a cohesive connection by means of welding would require that both the steering wires and the spatially adjustable disk have a nickel-titanium alloy. Consequently, the steering wires can have Nitinol as a nickel-titanium alloy without requiring increased effort in forming the connection between the steering elements and the spatially adjustable disk.
- Nitinol offers the advantage that it is very elastic and very robust under alternating loads.
- the non-positive connection enables quick and easy assembly without the steering elements cutting into and/or setting in the joint mechanism after tensioning. It is particularly advantageous that the clamping of the guided sections of the steering elements is carried out flexibly on the outer surface, the deflection contour and/or the inner surface of the spatially adjustable disk by means of the at least one clamping element.
- both a flat and a contoured outer surface and/or inner surface and/or a specific deflection contour can be used to guide and clamp the guided sections of the steering elements.
- the guided sections of the steering elements are pressed against the outer surface, the deflection contour and / or the inner surface of the spatially adjustable disk, whereby, due to the clamping force of the at least one clamping element, the steering elements are fastened to the spatially adjustable disk in such a way that they Depending on the coefficient of friction of the respective materials, they are firmly fixed in and/or on the spatially adjustable disk. Consequently, the clamping by means of the at least one clamping element prevents the steering elements from slipping up to a defined load.
- the tensile load on the steering elements can also be increased in a targeted manner by selecting the materials of the connecting partners through frictional forces and/or deflection along the outer surface, the deflection contour and/or the inner surface.
- the guided sections of the steering elements are at least partially guided along the outer surface, the deflection contour and/or the inner surface of the spatially adjustable disk and are clamped between the clamping element and the outer surface, the deflection contour and/or the inner surface, there is no or non-positive connection
- the strands of the steering elements will fray and make assembly more difficult or that a new steering element will even have to be inserted and/or threaded through a hole in the spatially adjustable disk. Consequently, the Assembly of the steering elements within the joint mechanism is significantly simplified and can be carried out more quickly.
- a core idea of the invention is that the proximal steering element ends are individually passed through the respective hole of the spatially adjustable disk and are guided on the proximal side of the spatially adjustable disk in a targeted manner at least partially along the outer surface, the deflection contour and/or the inner surface of the spatially adjustable disk and the guided sections of the steering elements are clamped by means of the at least one clamping element in a local position on the outer surface, the deflection contour and / or the inner surface, forming a non-positive connection, and thereby the steering elements are fastened to the spatially adjustable disk, without being next to the at least one Clamping element additional auxiliary materials and / or fasteners are required.
- a change in direction in the guidance of the steering elements along the surface of the spatially adjustable disk can be specifically exploited, thereby improving the strength of the non-positive connection and preventing the steering elements from slipping.
- both friction between the materials of the steering elements and the spatially adjustable disk as well as a flat transmission of the clamping force by guiding the steering elements along the outer surface, the deflection contour and / or the inner surface on the spatially adjustable disk can be used specifically for a stationary fixation.
