Problems solved by technology

Although the endoscopic vessel harvesting procedure is an improvement over the traditional "cut" procedure that requires a single, longer incision from the groin to the ankle, the endoscopic procedure remains tedious and difficult
In particular, current endoscopic harvesting systems require multiple tools, which not only increases the likelihood of damaging the bypass catheter but also increases the duration of the procedure described above

Embodiment Construction

[0023] The present disclosure provides an integrated device for endoscopic vessel harvesting. The present system for endoscopic vessel harvesting consists of several components. Typically, the main vessel is separated from the surrounding connective tissue by stripping the main vessel from the surrounding connective tissue using an endoscopic stripping device. Subsequently, the endoscopic cannula is used to introduce yet another device - the endoscopic branch sealing tool - to seal and sever the side branches. Once the side branches are sealed, another device is used to harvest a section of the main vessel for use as a bypass graft. The all-in-one device of the present disclosure combines the functions of stripping, branch sealing and severing, and optional main vessel sealing and severing, which may allow for reduced vessel manipulation and improved ease of use for the above procedure. The devices of the present disclosure may also be used to remove sealed and severed main ...

Abstract

An integrated endoscopic blood vessel collection device is disclosed. In some embodiments, such device (100) includes an elongated body (102) having a proximal end (104) and a distal end (104), a distal end (120), and a cutting unit (150). 106), the end (120) is provided at the distal end of the elongated body, the cutting unit (150) has a first cutting part (310) and a second cutting part (312), the first cutting part (310) and the second cutting part (312). The two cutting parts (312) are movable in the longitudinal direction relative to the elongated body (102) to capture the blood vessel between the first cutting part (310) and the second cutting part (312), and the first cutting part (310) and the second cutting portion (312) can circumferentially rotate about the tip (120) relative to each other to cut the captured blood vessel.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 61 / 782,034, filed March 14, 2013, U.S. Provisional Application No. 61 / 833,814, filed June 11, 2013, and U.S. Provisional Application No. 61 / 833,814, filed February 26, 2014. 14 / 190,873, each of which is hereby incorporated by reference in its entirety. technical field [0003] The presently disclosed embodiments relate to endoscopic cannulas and methods of use. Background technique [0004] Vessel harvesting is a surgical technique often used in conjunction with coronary artery bypass surgery. During bypass surgery, blood is rerouted around the blocked artery, restoring and improving blood flow and oxygen to the heart. The blood path can be re-routed using a bypass graft, wherein one end of the bypass graft is attached to the blood source upstream of the blocked area and the other end is attached downstream of the blocked area, thereby forming a bypass bypassin...
