Problems solved by technology

The solution of imitation instruments and their special insertion sequence makes this system impractical and complex for the user, since the user needs to know the configuration of the bracket assembly and the correct insertion sequence based on this configuration

example

[0099] Example: At high magnification, the user experiences zero force values. At low magnification, the user experiences high resistance. In this way, friction is the resistance experienced by the user, as in Figure 9 The implementation of "passive feedback" is shown.

[0100] Therefore, K=C1×(1-C2×DF)

[0101] in,

[0102] K=loop amplification factor, F3(s)

[0103] DF = demand force,

[0104] C1 and C2 are constants.

[0105] In order to provide an "active force feedback", the demand force DF / set force value SF must be controlled. In this case, the longitudinal motor produces resistance, see Figure 10 .

[0106] The user inserts instruments for endovascular procedures, such as catheters, balloons, guidewires, and the like, through the access tube 24 in the opening 22 . The instruments enter the cradles 16A-16C through the interconnecting member 26, which detect and control the instruments so that the motion of the instruments can be measured and feedback on the m...

Abstract

The present invention relates to a device ( 100 ) in a simulation system for simulating an interventional operation. The device ( 100 ) is arranged to receive a number of real instruments, preferably at least two. The device ( 100 ) comprises a number of moveable carriages ( 16 A- 16 C) corresponding to the number of the real instruments. The device ( 100 ) further comprises a track ( 20 ) and an interconnecting member ( 26 ). The interconnecting member ( 26 ) interconnects the carriages ( 16 A- 16 C) serially. Each carriage ( 16 A- 16 C) is provided with an opening for enabling reception of the instruments. Each carriage ( 16 A- 16 C) further comprises members to receive and lock at least one instrument, and members for receiving a movement from the instrument and generating a force, fed back to the instrument with respect to a simulation characteristic.

Description

technical field [0001] The present invention relates to a device in a simulation system for simulating interventional procedures, preferably procedures for internal blood vessels. Background technique [0002] The principles of adult education, the tenets of practical learning, and theories devoted to the development of specialized skills, all emphasize the crucial role of experience in the learning process. [0003] Simulation techniques are successfully used in surgical and medical education today and provide trainees and medical practitioners with the necessary learning experiences based on the theoretical foundations of these educations. All learners have the opportunity to acquire basic skills and achieve a prescribed level of qualification based on a standard learning experience. Simulations simplify learning by assessing performance and providing immediate, individual and detailed feedback. Simulation provides control settings that can be repeated until a defined le...
