YY/T 0980.4-2016Biopsy needles for single use - Part 4: Mechanical complete type (English PDF)

Foreword

YY/T 0980 "Biopsy needles for single use" series of standards consist of the following parts.

- Part 1. General requirements;

- Part 2. Manual biopsy needle;

- Part 3. Mechanical assembly type - Part 4. Mechanical complete type.

This Part is Part 4 of YY/T 0980 "Biopsy needles for single use".

This Part is drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

This Part of YY/T 0980 specifies the requirements for mechanical complete type biopsy needles for single use.

This Part does not provide requirements and methods for sampling performance and ultrasonic development, because currently there is no suitable test methods and simulation test materials.

In view of the fact that the structure type of mechanical complete type biopsy needles and the location, depth, state, texture and method of the puncture are different, this Part does not specify the puncture force. However, manufacturers are encouraged to determine appropriate puncture force by verifying, combining the specific structure and use of the mechanical complete type biopsy needle produced by each of the manufacturers.

In view of the fact that the trigger device of mechanical complete type biopsy needles may be mistakenly triggered in the course of clinical use, and there is no suitable test method for trigger devices, this Part does not specify the trigger device. However, manufacturers are encouraged to determine appropriate trigger device data and test method by verifying.

1 Scope

This Part of YY/T 0980 specifies the requirements for biopsy needles for single use - mechanical complete type (hereinafter referred to as "biopsy needles").

This Part applies to mechanical complete type biopsy needles for single use, of which the needle for single use and the mechanical power device are assembled together at the time of manufacture; the mechanical power device is for automatic or semi- automatic cutting operations to collect biopsy samples.
