Problems solved by technology

[0006] However, when the object to be treated is small and the amount of operation of the treatment part or the amount of deformation of the object to be treated is small, it is difficult to understand the application of force to the object to be treated.
For example, in the case where the treatment part is a clamping part and the clamping part clamps small parts such as surgical needles and surgical threads, it is difficult to understand the application of the clamping force to the treated object even if the clamping part is visually observed

no. 1 approach

[0046] Although the first embodiment of the present invention will be described below, an example of a medical treatment tool (hereinafter simply "treatment tool") of the present embodiment and a medical manipulator system to which the manipulator is applied will be described.

[0047] figure 1It is a schematic diagram showing a configuration example of a medical manipulator system to which the medical treatment tool according to the first embodiment of the present invention is applied.

[0048] figure 1 An example of a master-slave medical manipulator system is shown. A master-slave medical manipulator system is a system that has two arms including a master arm and a slave arm, and remotely controls the slave arm to follow the master arm to operate. The manipulator of the first embodiment of the present invention can be applied as this slave arm.

[0049] figure 1 The medical manipulator system shown has an operating table 100, slave arms 200a, 200b, 200c and 200d (man...

[0208] Next, a second embodiment of the present invention will be described.

[0209] Figure 12A A state in which the treatment part of the medical treatment tool according to the second embodiment of the present invention is opened is shown. Figure 12B A state in which the treatment part of the medical treatment tool according to the second embodiment of the present invention is closed is shown. Figure 12C It is a schematic partial sectional view showing a state in which the treatment part of the medical treatment tool according to the second embodiment of the present invention is closed and the clamping force is increased.

[0210] Such as Figure 12A As shown, the treatment tool 1F (medical treatment tool) of this embodiment includes a treatment part 10F instead of the treatment part 10 of the treatment tool 1 of the first embodiment, and similarly to the first embodiment, the treatment tool 1F can be mounted on the slave arm 200a to 200d and used as figure 1 Proced...

Abstract

A medical treatment tool includes a treatment section which has a pair of treatment tool pieces that is rotatably supported with respect to a substrate, a manipulating member which rotates the pair of treatment tool pieces, and opens and closes the pair of treatment tool pieces, a link member which has a first end and has a second end, a coupling member which couples the link member and the manipulating member at the second end; a movement indicating part which moves interlocking with a movement of the coupling member in an advance and retraction direction of the manipulating member and is provided so that an amount of movement with respect to the substrate is visually recognized from an outside of the substrate; and a reference index part which is provided at the substrate and refers to a amount of relative movement of the movement indicating part to the substrate.

Description

technical field [0001] The present invention relates to a medical treatment tool and a manipulator comprising the medical treatment tool. [0002] This application claims priority from Japanese Patent Application No. 2011-244385 filed on November 8, 2011, the contents of which are hereby incorporated by reference. Background technique [0003] Traditionally, medical practitioners have been used in the medical field to hold or press living tissue, surgical instruments, etc. to perform surgery. [0004] These medical treatment tools are introduced into a patient's body cavity for various types of surgery by being attached to a manipulator constituting, for example, a master-slave medical manipulator system or inserted through a forceps channel of an endoscope. [0005] In such medical treatment tools, manipulation force is transmitted to the treatment portion at the front end via a link coupled to a manipulation member such as a wire or a rod, and operations such as opening a...
