Description

Technical Field

[0001] The present invention designs a fixing device adapted to breast tissue, belonging to the field of medical devices. Background Art

[0002] Breast tissue is loose and has a certain elasticity. In many cases, it is necessary to effectively fix breast tissue to improve the accuracy of examination or the precision of surgery. Existing breast fixing devices use pressing plates, clamps, etc. to compress and fix breast tissue, which is likely to cause discomfort or even pain to patients. In addition, compression fixation lacks flexibility and cannot adapt to the differences in breast anatomical structures of different patients. The compression fixation effect is limited and cannot ensure sufficient strength in various different operation scenarios. Therefore, it is necessary to design a fixing device that is comfortable, flexible, easy to operate, and can adapt to breast tissue to achieve the purpose of using breast fixing devices in multiple scenarios.
