一種新型不使用釘子的手術(shù)吻合設(shè)備以熱塑型記憶的鎳鈦合金為基礎(chǔ)，利用機(jī)體自然愈合過(guò)程來(lái)吻合兩個(gè)中空管狀器官，例如結(jié)腸或者小腸。

使用這種新型設(shè)備，外科醫(yī)生就能夠進(jìn)行連續(xù)的幾乎無(wú)縫的縫合，而無(wú)需永久包埋例如釘子這樣的物體。這樣腸道內(nèi)腔就就可以重新獲得天然的管腔大小和彈性。這種設(shè)備具有生物兼容性， 核磁共振檢測(cè)不出，而X線檢測(cè)是不透明的。這種設(shè)備與不銹鋼相比，更加穩(wěn)定，不易被腐蝕。

這種新型吻合設(shè)備是由Niti醫(yī)療科技公司(Netanya, Israel)研制開發(fā)的。該系列產(chǎn)品已經(jīng)得到了美國(guó)食品藥品管理局(FDA)的許可。該公司的產(chǎn)品能夠被用于進(jìn)行邊緣－邊緣、末端－邊緣、末端－末端的壓縮的加壓吻合，能夠用于開放的、腹腔鏡、以及用手輔助的外科手術(shù)。

該系列產(chǎn)品包括加壓吻合夾(CAC)，能夠確保將邊緣-邊緣腸道夾在一起；加壓吻合環(huán)(CAR)，用于經(jīng)過(guò)胃腸道的末端－末端和末端－邊緣吻合；以及釘子組織閉合(STC)設(shè)備，叫做Hand STC，單手操作就能夠確保進(jìn)行精確定位、切割以及在任何進(jìn)行裝訂階段的再次定位。
 
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.
