APPARATUS FOR SIMULATING INSERTION OF AN ELONGATED INSTRUMENT INTO A STRUCTURE PROVIDING AXIAL ROTATING CONNECTION OF THE ELONGATED INSTRUMENT TO A CARRIAGE
First Claim
1. An apparatus for simulating insertion of an elongated instrument into a structure comprising:
- a casing having an aperture for receiving a distal end of the elongated instrument therethrough;
a longitudinal guide fixedly mounted in the casing;
a carriage comprising a mounting plate for mounting the distal end of the elongated instrument, the carriage being slidably mounted onto the longitudinal guide for translation therealong according to a translation of the elongated instrument through the aperture of the casing, the mounting plate comprising a receiving portion rotatably mounted thereto for receiving a corresponding attaching portion mounted at the distal end of the elongated instrument to provide an axial rotation connection of the elongated instrument to the carriage;
a carriage position sensing element for sensing a longitudinal position of the carriage along the longitudinal guide; and
a feedback force actuator mounted on the carriage and operatively connected to the casing for applying an adjustable resistive force to a translation of the carriage on the longitudinal guide according to the sensed position of the carriage and resistance characteristics of the structure.

Abstract
The present disclosure relates to an apparatus for simulating insertion of an elongated instrument into a structure. The apparatus comprises a casing having an aperture for receiving a distal end of the elongated instrument therethrough and a longitudinal guide fixedly mounted in the casing. The apparatus has a carriage for mounting the distal end of the elongated instrument, the carriage being slidably mounted onto the longitudinal guide for translation therealong according to a translation of the elongated instrument through the aperture of the casing. The apparatus comprises a carriage position sensing element for sensing a longitudinal position of the carriage and a feedback force actuator for applying an adjustable resistive force to a translation of the carriage on the longitudinal guide according to the sensed position of the carriage and resistance characteristics of the structure. The present disclosure also relates to a medical insertion simulator comprising such an apparatus.
