Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document. GB/T 16886.2 Biological evaluation of medical devices Part 2.Animal welfare requirements3 Terms and definitionsThe terms and definitions defined in GB/T 16886.2 and the following apply to this document. 3.1 hernia The internal organs or tissues leave their normal anatomical parts and enter another place through weak points, defects or pores formed by nature or acquired. parts. 3.2 incisional hernia Hernia at the site of surgical incision. Note. Generally seen after abdominal surgery, the deep fascial layer is split or not healed, causing the internal organs or tissues to protrude into the normal abdominal wall under the action of intra-abdominal pressure. outside the layer plane.4 animal choicesExperimental animals of qualified quality should be used. It is advisable to fully consider the anatomical structure of the abdominal wall and the degree of neoperitonealization between animals and humans. of comparability. It is recommended to use healthy non-pregnant experimental pigs, whose weight is generally not less than 40kg. If other species of animals are selected, their suitability should be Be explained. The number of animals should be selected based on factors such as the purpose of the experiment, design type, evaluation indicators and accuracy of evaluation methods, as well as statistical factors. Let’s consider it comprehensively. It is recommended that the animal sample size of the test sample group and the control sample group that completes the effective test at the final observation point is not less than 10.5 Main instruments and equipmentCommonly used surgical instruments, animal anesthesia monitoring equipment, laparoscopy (optional), universal tensile machine, pathological examination equipment, etc. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YY/T 1754.3-2023_English be delivered?Answer: Upon your order, we will start to translate YY/T 1754.3-2023_English as soon as possible, and keep you informed of the progress.
