This application is directed to a surgical stapling device for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. A tactile indication mechanism is also provided for notifying a surgeon that the device has been fired and for notifying a surgeon that the anvil head has been unapproximated a distance sufficient to permit the anvil head to tilt.

Surgical stapling device for performing circular anastomoses

A surgical device is described herein that can be used to fire different types and sizes of disposable loading units. In a preferred embodiment, the device applies parallel rows of surgical fasteners to body tissue and concomitantly forms an incision between the rows of staples during an endoscopic or laparoscopic surgical procedure. The device can be utilized with disposable loading units configured to apply linear rows of staples measuring from about 15 mm in length to about 60 mm in length and can be used to fire disposable loading units containing surgical clips and individual staples.

Surgical stapler

There are disclosed various embodiments of a balloon dissector and balloon tip cannula assembly which are provided to facilitate forming an anatomical space within the body, such as, for example, an anatomical space in the abdominal cavity or extraperitoneal space for facilitating hernia repair surgeries. The balloon dissector and balloon tip cannula assembly generally includes a balloon tip cannula assembly for anchoring the device to the abdominal wall and a balloon dissector assembly having a dissection balloon at a distal end for separating apart tissue layers and forming an anatomical space. Various structures are provided to connect the balloon dissector assembly to the balloon tip cannula assembly. Obturators associated with the balloon dissector assembly and the balloon tip cannula assembly may also be provided. The balloon dissector and balloon tip cannula assembly may also include a scope support for insertion through the balloon dissector assembly and dissection balloon and for receipt of an endoscope to view the procedure from within the balloon. Various combinations of valve ports and sub-assemblies are disclosed for providing inflation fluid to the balloon tip cannula assembly, insufflation fluid for the abdominal cavity and inflation fluid for the dissection balloon.

Balloon dissector with cannula

This application is directed to a surgical stapling device for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The handle portion includes a rotatable approximation knob for approximating the anvil and shell assemblies and a firing trigger for actuating a firing mechanism for ejecting staples positioned within the shell assembly. The firing trigger forms one link of a two bar linkage provided to actuate the firing mechanism. The anvil assembly includes a tiltable anvil which will tilt automatically after firing of the device and unapproximating the anvil and shell assemblies. The head portion also includes a retractable trocar assembly which is slidably positioned within an anvil retainer and is automatically advanced and retracted upon attachment and detachment of the anvil assembly onto the anvil retainer, and a lockout tube.
