Embodiment Construction

[0035] Below, refer to Figure 1 to Figure 7 The first embodiment of the present invention will be described, but before that, an example of a medical manipulator system to which the medical device of this embodiment is applied will be described.

[0036] figure 1 It is a figure which shows an example of a medical manipulator system, and shows the medical manipulator system of a master-slave system. The master-slave medical manipulator system refers to a system that has two types of arms including a master arm and a slave arm, and remotely controls the slave arm so that the slave arm follows the movement of the master arm.

[0037] figure 1 The illustrated medical manipulator system includes an operating table 100, slave arms (manipulators) 200a to 200d, a slave control circuit 400, master arms 500a, 500b, an operation unit 600, an input processing circuit 700, an image processing circuit 800, and a display 900a. , 900b.

[0038] The operating table 100 is a platform on wh...

Abstract

This medical instrument comprises: an end effector that executes a prescribed function; a motor unit that generates motive force that drives the end effector; a transmission member that is connected to the end effector and to the motor unit and that transmits motive force to the end effector; a tensile force generating unit that has a tension pulley that is connected to the tensile force generating unit and that is in contact with the transmission member, and that, by means of the movement of the tension pulley, maintains at a prescribed magnitude the tensile force that acts on the transmission member; and a fixing part that can hold the position of the tension pulley.

Description

technical field [0001] The present invention relates to a medical device, and more specifically, relates to a medical device used to be inserted into a patient's body and an adjustment method of the medical device. This application claims priority based on Japanese Patent Application No. 2014-142574 filed in Japan on July 10, 2014, the contents of which are cited here. Background technique [0002] Conventionally, medical equipment having an end effector for observation and treatment at the end of an elongated insertion portion has been widely used. In such a medical device, a driving force may be transmitted to the distal end side in order to bend the insertion portion or drive the distal end effector. As a transmission member for transmitting a driving force, a single wire or a twisted wire formed of a metal bare wire is usually used. [0003] When the insertion portion of the medical device is a flexible insertion portion, the insertion portion may meander or bend when ...
