Sanarus公司的Cassi微创乳房活检设备投入使用

这种新型可转动的大核心乳房活检设备，是一种全自动一次性的手工操作的设备。该设备对乳房造成的创伤最小，是传统乳房活检设备很好的替代选择。

该设备被称作Cassi，操作方便而且无需准备时间、无需固定设备的投资，节约医护人员的时间与医疗成本。设备采用了专利保护的“棒状冷冻”工艺，能够传递体积大、精细的组织标本，减少了传递次数。每次在一个地方，Cassi迅速使用“棒状冷冻”方法固定病变组织，确保了活检针接触靶组织的安全。切割套管然后迅速转动穿刺针获取组织样本。该设备能够获得较大块组织，证明其比细穿刺针吸入方法更加可靠，能够帮助医生对病变性质做出准确诊断。

Cassi设备与棒状冷冻工艺是由Sanarus医疗公司(Pleasanton, CA, USA)研制成功的。在医生诊疗室发现患者有房结节的时候，就能够使用Cassi当场进行快速活检，而且只需要局部麻醉。这就免除了患者预约回访接受活检的麻烦，而且患者精神上的压力也较小。

美国Lemoyne(PA, USA)私人开业的乳房外科医生Angela Soto Hamlin医生解释说：“最近，使用Cassi的确很好地帮助我从我的患者获取高质量组织标本。而使用这些标本，我就能够做出更加准确的诊断。而且帮助我避免了为患者另外安排时间预约进行活检或者送患者到手术室。”

Minimally Invasive Breast Biopsy Device
 
A new rotational large-core breast biopsy device is a fully automated, disposable handheld device that offers a minimally invasive alternative to traditional breast biopsy devices.

Called Cassi, the device requires no set-up time, performs quickly, and requires no capital equipment investment, saving doctors time and cost. The device uses proprietary Stick Freeze technology to deliver large, precise tissue samples with fewer passes. Once in place, Cassi quickly immobilizes the lesion with a “stick freeze” that secures the targeted tissue to the biopsy needle. A cutting cannula then rotates quickly over the needle to obtain the tissue sample. Larger tissue samples are proving more reliable than fine-needle aspirations in helping doctors to accurately diagnose the nature of a lesion.

Cassi and Stick Freeze were developed by Sanarus Medical, Inc. (Pleasanton, CA, USA). When a breast lump is detected during a visit to a doctor’s office, Cassi can be used to perform a biopsy immediately and with local anesthesia. This may eliminate the need to schedule a return visit to perform the biopsy and is less stressful for patients.

“Recently, Cassi proved instrumental in helping me obtain a quality tissue specimen from one of my patients,” explained Dr. Angela Soto Hamlin , a private-practice breast care surgeon in Lemoyne (PA, USA). “From this specimen I was able to make a more accurate diagnosis, one that helped me avoid the delay of scheduling her biopsy for another day or sending her to the operating room.”
