Medical electrical equipment employing robotic
technology - Classification
1 *Scope
This Standard specifies terms and definitions, classification of medical electrical equipment employing robotic technology (hereinafter referred to as the
equipment) or medical electrical system (hereinafter referred to as the system). NOTE: The chapters and articles with an asterisk (*) in this Standard have explanations for relevant principles in Annex A.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 2.1 * medical electrical equipment/system employing robotic technology
medical electrical equipment or medical electrical system that has two or more programmable axes or programmable continuous axes, and a certain degree of autonomy to imitate, assist or replace medical staff to perform specific tasks NOTE 1: Each axis is controlled and coordinated by the control system.
NOTE 2: See IEC/TR 60601-4-1 for the degree of autonomy.
2.2 axis
a direction line that is used to define the device to move in a straight line or rotation
NOTE: "Axis" is also used to mean "mechanical joints of equipment".
NOTE 2: Rewrite GB/T 12643-2013, definition 4.3.
2.3 medical electrical equipment
electrical equipment that has an application part or transmits or obtains energy to the patient or detects these transmitted or obtains energy; such electrical equipment:
a) has no more than one connection to a specified power supply network, problem with human body function or structure, such as severe deviation or loss of function or structure
2.9 * movement function
including one or more sensory, neuromusculoskeletal, or sports-related human functions; these human functions implement motion control
NOTE: "Sensory", "neuromusculoskeletal" and "sports-related" come from the World Health Organization (WHO) classification of body functions.
2.10 body functions
physiological functions of the human system (including pathological functions) [ISO 9999:2016, definition 2.4]
2.11 body structures
anatomical parts of the human body such as organs, limbs and their
[ISO 9999:2016, definition 2.5]
2.12 * placement
positioning, holding or fixing of surgical instruments intended for use in the equipment or system
2.13 manipulation
usually grasp and/or move objects with multiple degrees of freedom, such as tissues or surgical instruments
NOTE: Rewrite GB/T 12643-2013, definition 2.1.
2.14 master-slave control
a control method that the equipment or system slave unit (slave) reproduces the master unit (master) movement
NOTE: Rewrite GB/T 12643-2013, definition 5.3.4.
2.15 cooperative control
a control method that the equipment or system cooperates with the operator to complete the operation in its work space
2.16 hand-held
2.24 limbs
the parts of the human body excluding the head, neck, and trunk
2.25 * powered exoskeleton
medical electrical equipment that consists of externally powered electric orthotics; it is placed on the patient's paralyzed or weakened limb to provide the patient with mobility
2.26 orthosis
external use device for changing the structure and functional characteristics of neuromusculoskeletal system
[GB/T 14191.1-2009, definition 2.1.2]
2.27 home healthcare environment
patient's residence or other location where the patient is located, excluding medical institutions where a trained operator is present as long as the patient is present
Examples: Cars, buses, trains, ships or airplanes, as well as wheelchairs or outdoor walking environments.
NOTE 1: A medical institution refers to an institution that has been registered and obtained a "Medical Institution Practicing License" in accordance with the "Medical Institution Management Regulations" and the "Implementation Rules of the Medical Institution Management Regulations".
NOTE 2: Other places where patients appear include outdoor environments where they walk or travel by car.
NOTE 3: Rewrite IEC 60601-1-11:2015, definition 3.1.
3 * Classification
3.1 According to expected purpose
3.1.1 Used to assist surgery According to clinical use, it is classified into used to place surgical instruments and manipulate surgical instruments. According to control mode, it is classified into master-slave control and cooperative control.
Annex A
Principle explanation
A.1 Explanation of standard name
The standardized objects to which this Standard applies are usually called robots for medical use and medical robots. However, there is no universally recognized definition of "robots for medical use" and "medical robots", and there are several problems:
- Subject dislocation. According to international standards, such products are medical electrical equipment or system that use robotics technology, not robots.
- Unclear scope. At present, dispensing robots and medical service robots have appeared on the market. These products are completely inconsistent with the administrative departments, product risk points and
implementation standards of medical electrical equipment, and it is difficult to confuse them.
- According to the "Rules for the Naming of Common Names of Medical
Devices", medical devices of the same type with the same or similar
expected purpose and common technology shall use the same common
name. But the intended purpose of medical electrical equipment or system using robotics is very broad, including usage for surgery assistance,
rehabilitation, compensation. It is not scientific to use a generic name to cover all expected purposes, nor does it meet the requirements of medical device regulations and registration review requirements.
Therefore, inspired by the terms of US Food and Drug Administration (FDA) and international standards, the name of the standardization object to which this Standard applies is determined to be medical electrical equipment or system that used robotics. The name is not a generic name for this type of product. It clarifies the subject of this type of product. At the same time, it clarifies the technical characteristics of this type of product that distinguish it from other medical electrical equipment or systems. For products of this type with different expected purposes, the specific general name is determined according to the requirements of the naming rules.
