: Vacuum-assisted excision (VAE) is a minimally invasive technique for breast tumor treatment, offering precision, comfort, and quick recovery. It is widely used for benign breast lesions and is playing an increasingly important role in the therapeutic management of non-surgical patients or patients who refuse surgery. Optimal outcomes require an understanding of device features to tailor treatment to each lesion. The Mammotome Elite 10G operates in a fixed mode, while the Mammotome Revolve EX 8G offers multiple aspiration levels and aperture windows for greater versatility. This study analyzed the specimen features (weight and length), comparing the weight obtained from two different VAE systems to aid the appropriate selection of a device based on the clinical setting. It also determined the number of specimens needed to achieve the 4 g diagnostic threshold. : The Mammotome Elite 10G and the Mammotome Revolve EX were evaluated under controlled conditions. For Mammotome Revolve EX, combinations of five aspiration levels and three aperture lengths (12 mm, 18 mm, and 25 mm) were tested. Twelve samples were collected from a chicken breast phantom for each setting. Specimen weights and the minimum excisions required to reach the 4 g threshold were analyzed. : The mean weight per sample for the Mammotome Elite 10G was 0.16 ± 0.04 g. For the Mammotome Revolve EX, the weights increased with aperture size and aspiration level, ranging from a minimum of 0.132 ± 0.028 g (a window length of 12 mm and aspiration level 1) to a maximum of 0.407 ± 0.055 g (a window length of 25 mm and aspiration level 5). The 25 mm window at aspiration level 5 achieved the 4 g threshold in as few as 10 samples. By comparison, the Mammotome Elite required up to 26 samples. : Compared to the Mammotome Elite, Mammotome Revolve EX offers superior versatility and efficiency, reducing patient discomfort by minimizing the required samples. Its technical advantages make it a valuable tool for both diagnostic and therapeutic applications.
真空辅助切除（VAE）是一种用于乳腺肿瘤治疗的微创技术，具有精准、舒适和恢复快的特点。它广泛应用于乳腺良性病变，并在非手术患者或拒绝手术的患者的治疗管理中发挥着越来越重要的作用。要获得最佳效果，需要了解设备特性，以便针对每个病变量身定制治疗方案。Mammotome Elite 10G以固定模式运行，而Mammotome Revolve EX 8G提供多种抽吸水平和孔径窗口，具有更高的通用性。本研究分析了标本特征（重量和长度），比较了从两种不同的VAE系统获得的重量，以帮助根据临床情况适当选择设备。研究还确定了达到4g诊断阈值所需的标本数量。
在受控条件下对Mammotome Elite 10G和Mammotome Revolve EX进行了评估。对于Mammotome Revolve EX，测试了五种抽吸水平和三种孔径长度（12mm、18mm和25mm）的组合。每种设置从鸡胸模型中采集12个样本。分析了标本重量以及达到4g阈值所需的最小切除量。
Mammotome Elite 10G每个样本的平均重量为0.16±0.04g。对于Mammotome Revolve EX，重量随孔径大小和抽吸水平增加，范围从最低的0.132±0.028g（窗口长度12mm，抽吸水平1）到最高的0.407±0.055g（窗口长度25mm，抽吸水平5）。抽吸水平5的25mm窗口仅需10个样本就能达到4g阈值。相比之下，Mammotome Elite需要多达26个样本。
与Mammotome Elite相比，Mammotome Revolve EX具有更高的通用性和效率，通过减少所需样本量减轻了患者的不适。其技术优势使其成为诊断和治疗应用的宝贵工具。
