40 results about "End to side anastomosis" patented technology

End-to-Side Anastomosis Anastomoses are the connections that join arteries together to create a bypass. The Greek roots of the word translate to “furnish with a mouth,” which in this case means creating an outlet in one tube that connects with an opening in another tube to form a branching network.

Methods and apparatus for forming anastomotic sites

Apparatus and methods are provided for forming a working space on the interior wall of a blood vessel, such as the aorta. The working space is isolated from blood flow and permits creation of an anastomotic hole and subsequent suturing of the hole to form an end-to-side anastomosis, even while the heart is beating. The apparatus comprises tools including inflatable barriers, such as cup-shaped balloons, which engage the inner wall of the blood vessel with minimum trauma and maximum sealing. In a first embodiment, the inflatable barrier is introduced through a penetration at the site of the anastomotic attachment. In a second embodiment, the inflatable barrier is introduced through a second penetration axially spaced-apart from the site of the anastomotic attachment.

Pneumoperitoneum closing device for laparoscopic operation

The invention relates to a pneumoperitoneum closing device which performs gastrointestinal and gastroesophageal end-to-side anastomosis under a total laparoscope by using a tubular anastomat in a laparoscopic gastrointestinal operation. By the pneumoperitoneum closing device, the defects that the tubular anastomat used in the laparoscopic gastric cancer operation in the prior art is inconvenient to operate and air leakage is easily caused are overcome. The pneumoperitoneum closing device comprises an operating panel which is arranged on the top and is provided with a plurality of sealed operating holes, a sleeve which is arranged at the bottom, has appropriate elasticity and is matched with an incision of an abdominal wall of a human body and a flexible connection part which is connected with the operating panel and the sleeve, wherein the end part of the sleeve is provided with a blocking part, and the other end of the sleeve is provided with a turnover clamping part; the sleeve is inserted into the incision of the abdominal wall; the blocking part is positioned inside an abdominal cavity, the clamping part is positioned outside the abdominal cavity, and the blocking part plays a role in blocking to prevent the sleeve from being separated from the incision, and the clamping can be pressed on the abdominal wall in a turnover mode; and elasticity generated by the sleeve is extruded on the wall of the incision to play a role in sealing. The pneumoperitoneum closed device has a one-hole and multi-channel structure and is convenient to operate, and the operation cost is saved.

Vascular clip

A vascular clip for use in end-to-side anastomoses having a handle connected to a lower ring and an upper ring. The handle includes a resilient element biasing the two rings together so that the rings are closely juxtaposed when the clip is closed. The respective facing surfaces of each of the rings may be provided with a rough surface. A graft vessel or an artificial aneurysm may be sutured to the lower ring. The graft vessel or artificial aneurysm may be autologous or heterologous material or may be made of synthetic material. The handle may fit into a clip applier that facilitates the application of the clip. The handle and the clip applier may be of different shapes depending on the various applications of the clip. The rings may also have different shapes and sizes to accommodate different kinds of anastomoses and different vessels of all sizes in all parts and cavities of the human or animal body. The two rings are substantially the same dimension, which preferably may be in the range of from around 2 mm up to around 2.5 cm.

Elastic compressed anastomosis device

A surgical anastomosis apparatus is suitable for the end-to-side anastomosis of a minor-caliber hollow viscus and a heavy-caliber hollow viscus, thus effectively avoiding various complicating diseases caused by the prior art. The technical proposal comprises a frame pipe, a fairlead connected with the frame pipe, a puncture needle connected with the fairlead, an elastic circular pressuring sheet and an installation sleeve. The invention makes full use of the certain tension existing in an anastomosis joint and the elasticity of the elastic circular pressuring sheet. The good combination of the tension and the elasticity causes the anastomosis joint to be firmer. The anastomosis is pressurized circularly and continuously; the lamination is correct and the operation is easy. The fairlead can be used for drainage and can be pulled out with the frame pipe after the operation in external drainage. And in internal drainage, the fairlead can be used for discharging out from a body by a larger lumen after the necrotic tissue at the inner edge of the anastomosis joint drops off after being pressurized without foreign matter left, thus preventing the blooding, the leakage, the fistula and the stenosis of the anastomosis joint to a certain extent. In addition, a structure which is similar to papillary and is formed on the wall of the heavy-caliber hollow viscus at the anastomosis joint possibly prevents back streaming.
