Embodiment Construction

[0028] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

[0029] (Example of the overall structure of the surgical support system)

[0030] First, refer to figure 1 An example of the overall configuration of the surgery assisting system of the present invention will be described. figure 1 An example of the functional configuration of the surgery assisting system 1 according to the present embodiment is schematically shown. The surgical assisting system 1 of the present embodiment includes a surgical assisting device 2 and a medical instrument drive unit 11 that controls the posture of a surgical tool or an end effector.

[0031] In addition, the operation assisting device 2 includes, for example, a position and posture measuring device 22 for measuring the posture of a surgical tool (handheld medical device 21 ) held by the operator, and a mode switching unit 3 for switching the control state. , the cont...

Abstract

Provided are a surgical assistance device, a control method therefor, and a surgical assistance system. The surgical assistance device can measure the movement of the medical instrument inserted intothe body cavity in the linear movement direction with high precision. The surgical assistance device can be operated by using a surgical tool inserted into a body cavity; the surgical assistance device is provided with a measuring unit. And a measurement means for measuring the insertion depth and insertion angle of the surgical tool inserted into the body cavity in the axial direction of the bodycavity. And a measurement means for measuring the insertion depth by measuring an acoustic wave propagating through a space between a transmitter attached to one of the surgical tools and a transmitter attached to the other receiver, the transmitter and the receiver being located within a prescribed range from the insertion position into which the surgical tool is inserted into the body cavity, as an input of an operation.

Description

technical field [0001] The present invention relates to an operation assisting device, a control method thereof, and an operation assisting system. Background technique [0002] Laparoscopic surgery is known in which a plurality of small-diameter holes are made in the abdominal wall, and surgical tools held by the operator or medical instruments such as endoscopes are inserted into body cavities through the small-diameter holes. Generally, in laparoscopic surgery, the operator who operates a plurality of surgical tools such as an ultrasonic scalpel or forceps is assisted by a laparoscope operator (scopist) who operates a laparoscope, or an assistant who pulls organs with forceps, etc. Surgery is performed, so it sometimes becomes more complicated than laparotomy, which cuts the abdomen open. Therefore, instead of assisting a laparoscopic operator or the like, a technique of assisting an operator with a robot arm has been proposed (Patent Document 1, Patent Document 2). [...
