Embodiment Construction

[0021] figure 1 A user interface device 1 according to one embodiment of the invention is shown, schematically connected as part of a simulation system 2 .

[0022] The simulation system 2 comprises a processing unit 3 running simulation software for simulating a surgical procedure, and a display 4 for displaying a visualization of the simulation procedure to a user. The interface device 1 interfaces with the simulation system and allows a user to provide input to the system 2, thereby communicating with the simulation visible in the display device. The interface is haptic, that is, it is adapted to provide the user with force feedback from the simulation in at least some degrees of freedom of the interface.

[0023] The user interface device 1 comprises a movable instrument 10 having a handle 20 and a rigid shaft 21 pivotally suspended by a frame 11 . Such as figure 2 As shown, the frame 11 allows pivotal movement of the shaft 21 about the pivot point P, which is equivale...

Abstract

A tactile user interface device (1) for a surgical simulation system (2), comprising: a frame (11) having a fixed base (12), a neck rotatable about a first axis (A) relative to the base (12) part (15), and a suspension part (16) rotatable around a second axis (B) relative to the neck part (15); an instrument (10) having a rigid shaft suspended by the suspension part (16) ( 21) so as to be pivotable around a first axis (A) and a second axis (B); a first actuator and a second actuator (14, 17), which are mounted on the frame (11) and arranged to rotate around The first axis (A) and the second axis (B) provide force feedback to the user when rotating the instrument (10). The first actuator and the second actuator are mounted on the neck portion (15).

Description

technical field [0001] The present invention relates to a user interface device for a surgery simulation system, and in particular to a user interface device for simulating laparoscopic surgery. Background technique [0002] In recent years, in order to train doctors not to put patients in danger during various operations, surgical simulation systems have been increasingly used. Especially in the field of minimally invasive procedures, such as laparoscopy, endoscopy, colonoscopy, etc., these simulation systems have gained significant acceptance. During minimally invasive surgery, doctors often rely on images on the screen rather than actual images of the patient, and with the availability of powerful image rendering today, such images can be simulated with a very high degree of realism. [0003] In order to communicate with the simulation software, the simulation system also needs input devices, which are hardware that the doctor can operate and that simulate actual surgica...
