Ultrasonic medical device operating in a transverse mode

An ultrasonic medical device comprises an ultrasonic vibration generator that generates vibration along its longitudinal axis. The ultrasonic vibration is transmitted through an ultrasonic coupler and a series of transformer sections that amplify the ultrasonic vibration. A flexible member is coupled to the distal end of the transformer sections, and is thus supplied with a longitudinal vibration at its base by the transformer sections. The flexible member is designed so that it converts the longitudinal vibration into a standing wave that runs along the length of the flexible member. The standing wave produces a series of nodes and anti-nodes along the length of the flexible member. Each of the anti-nodes produces cavitation in fluids in contact with the probe. The cavitation of the fluids causes destruction of adjacent tissue. In this manner, the entire length of the flexible member becomes a working surface that may be utilized for destroying tissue.

Surgical purse string suturing instrument and method

A purse string suturing instrument is provided for quickly and effectively forming a purse string suture in tubular tissue through relatively small cannulas placed in the body. The instrument includes a pair of elongated jaws, each having a row of spaced-apart uniform-size teeth. The jaws are hinged together at one end to clamp the tubular tissue therebetween. The two rows of teeth are offset with respect to each other so that they mesh when the jaws are closed. The jaws are inserted through a cannula and positioned to close around the tissue to be sutured. The rows of teeth then bend the tissue between them into a wavelike configuration. A pair of needles, the ends of each being connected to a single length of suture, is then inserted through passageways provided through the teeth. An encircling series of stitches are thus formed in the wall of the tubular tissue to create a purse string suture. The needles and the suturing instrument are then withdrawn through the cannula. The tubular tissue can be snugly fitted over an anastomosis ring or the like by drawing and tying the purse string suture.
