Holder facility for holding a medical instrument

Abstract

A holder facility for holding a medical instrument includes a first receiving element, a second receiving element, and at least three diaphragm elements. The at least three diaphragm elements within a diaphragm layer are arranged between the first and second receiving elements about a common rotation axis. The first and second receiving elements each have an opening for receiving the medical instrument. The first and second receiving elements are movable around about the common rotation axis relative to one another. Each of the at least three diaphragm elements is forcibly moved by mechanical coupling. For a movement of the first receiving element relative to the second receiving element about the common rotation axis, there is a forcibly-guided movement of the at least three diaphragm elements such that the at least three diaphragm elements hold a medical instrument arranged in the opening of the first and second receiving elements.

Description

[0001]This application claims the benefit of German Patent Application No. DE 10 2019 214 868.9, filed on Sep. 27, 2019, which is hereby incorporated by reference in its entirety.BACKGROUND[0002]The present embodiments relate to a holder facility for holding a medical instrument.[0003]For the precise examination of an object to be examined (e.g., for vascular diseases and / or tumor diseases, as well as for interventions, such as for vasodilation and / or for placement of an angioplasty in the object being examined), elongated and / or flexible medical instruments are frequently used. In such cases, the object being examined may be a human and / or animal patient, for example. The medical instrument is further frequently embodied as a surgical instrument (e.g., as a catheter and / or guide wire, and / or as a diagnostic instrument, such as an endoscope with an ultrasound head for a transesophageal echocardiogram (TEE probe), and / or a bronchoscope). While the high mechanical flexibility and / or d...

AI Technical Summary

Benefits of technology

The patent text describes a method for arranging at least three diaphragm elements in a way that allows them to move while maintaining stability. Each diaphragm element can have two contact surfaces, which can reduce friction between them. The computer program described in the text can be executed quickly, repeatedly, and robustly, and can efficiently carry out the necessary processing acts. Overall, the patent text provides a technical solution for arranging diaphragm elements in a way that allows them to move while maintaining stability.

Problems solved by technology

While the high mechanical flexibility and / or deformability of the medical instruments frequently represents an important basis for use in an intervention and / or examination, precise guidance of the instrument may be rendered more difficult by the attributes.

In this facility (e.g., through friction between the guidance facility and the catheter), this may disadvantageously result in a torsion and / or deformation of the catheter.

This may render a precise guidance of the catheter as a medical instrument significantly more difficult.

The known robot-assisted facilities further frequently require a large amount of space, which may be a disadvantage, precisely in a clinical (e.g., surgical) environment.
