AI Technical Summary

Technical Problem

Existing interventional robots have low accuracy in detecting pushing resistance from the end, and the suspension of one end of the clamping mechanism increases sliding friction, affecting detection accuracy.

Method used

The clamping mechanism is mounted on the pallet mechanism, and the pressure detection component is located below the pallet mechanism. An elastic element is used to make the baffle abut against the pressure detection component. Linear bearings and slide rail assemblies are used to improve sliding stability. The rotary drive mechanism and the clamping drive mechanism are set independently to reduce inertia.

Benefits of technology

It improves the detection accuracy of pushing resistance, reduces the effects of sliding friction and inertia, and enhances the accuracy of detection.

Abstract

The application belongs to the field of interventional surgery medical instruments, and relates to a pressure detection device, which comprises a base, a supporting plate mechanism, a clamping mechanism, a pressure detection assembly and an elastic member. A limiting seat is arranged on the base. The supporting plate mechanism is slidingly arranged on the base. A baffle is arranged below the supporting plate mechanism. The clamping mechanism is arranged on the supporting plate mechanism and used for clamping an elongated medical instrument. The pressure detection assembly is arranged on the base. The elastic member is arranged between the limiting seat and the baffle, so that the baffle is abutted against a sensing end of the pressure detection assembly under the action of the elastic member. The application also relates to a driving device of an interventional robot. The technical scheme provided by the application can reduce the length of a force arm through which pressure is transmitted to the pressure detection assembly, reduce the mass of the pressure detection device, and improve the detection precision of the pressure detection device.
