Niti公司开发出不使用钉子的外科手术加压吻合设备

 
一种新型不使用钉子的手术吻合设备以热塑型记忆的镍钛合金为基础，利用机体自然愈合过程来吻合两个中空管状器官，例如结肠或者小肠。

使用这种新型设备，外科医生就能够进行连续的几乎无缝的缝合，而无需永久包埋例如钉子这样的物体。这样肠道内腔就就可以重新获得天然的管腔大小和弹性。这种设备具有生物兼容性， 核磁共振检测不出，而X线检测是不透明的。这种设备与不锈钢相比，更加稳定，不易被腐蚀。

这种新型吻合设备是由Niti医疗科技公司(Netanya, Israel)研制开发的。该系列产品已经得到了美国食品药品管理局(FDA)的许可。该公司的产品能够被用于进行边缘－边缘、末端－边缘、末端－末端的压缩的加压吻合，能够用于开放的、腹腔镜、以及用手辅助的外科手术。

该系列产品包括加压吻合夹(CAC)，能够确保将边缘-边缘肠道夹在一起；加压吻合环(CAR)，用于经过胃肠道的末端－末端和末端－边缘吻合；以及钉子组织闭合(STC)设备，叫做Hand STC，单手操作就能够确保进行精确定位、切割以及在任何进行装订阶段的再次定位。
 
Staple-Free Compression Anastomosis
 
New staple-free anastomosis devices are based on a nickel titanium alloy with thermal-shape memory and use the body’s natural healing process to reconnect two hollow, tubular organs such as the colon or intestines.

The new devices enable a surgeon to create a continuous almost seamless seal without the need for permanently embedded objects such as staples. As a result, the inner channel of the intestine is able to regain its natural tubular size and flexibility. The devices are biocompatible, are undetectable by magnetic resonance imaging (MRI), and are opaque to x-rays. They are also more stable and less subject to corrosion than materials such as stainless steel.

This new line of anastomosis devices was developed by Niti Medical Technologies (Netanya, Israel). The line has been cleared by the U.S. Food and Drug Administration (FDA). The company’s devices can be used to perform side-to-side, end-to-side, and end-to-end compression anastomosis in open, laparoscopic, and hand-assisted surgery.

The line comprises the compression anastomosis clip (CAC), which securely clamps together side-to-side intestine; the compression anastomosis ring (CAR), designed to create end-to-end and end-to-side anastomoses throughout the gastronintestinal tract; and a stapling tissue closure (STC) device called Hand STC, a one-hand operation that enables accurate positioning, cutting, and repositioning at any stage of the stapling process.
