2271761, 227 19, 2271751, 606139, 606219

Abstract:

Introducers for introducing a surgical circular stapler into a patient. Various embodiments comprise a hollow flexible sheath that has a distal end and an open proximal end that is sized to receive a stapling head portion of the circular stapler therein. A rigid cap assembly is attached to the distal end of the hollow flexible sheath. The rigid cap assembly may be configured to selectively move between a closed position wherein a distal face of the stapling head is covered when inserted therein and an open position wherein the cap assembly may be withdrawn from around the stapling head and elongated shaft. A release arrangement interfaces with the rigid cap assembly such that upon an application of a release motion thereto, the rigid cap is movable from the closed position to the open position.

US Classification:

2271751

Abstract:

Introducers for introducing a surgical circular stapler into a patient. Various embodiments comprise a sheath that defines a first lumen that has a closed end and an open end. The first lumen may be sized to receive at least a distal end portion of the stapling head of the stapler within the closed end. The sheath may have a weakened area therein such that upon an application of a release motion thereto, the weakened area ruptures to permit the hollow sheath to be removed from the stapler.

Abstract:

Introducers for introducing a surgical circular stapler into a patient. Various embodiments comprise a hollow flexible sheath that has a distal end and an open proximal end that is sized to receive a stapling head portion of the circular stapler therein. A radially-openable barrel member is attached to a distal end of the hollow flexible sheath to define an opening for receiving the stapling head therein. A rigid cap member is hingably attached to the radially-openable barrel member and is movable between a closed position wherein the rigid cap member covers a distal end of the opening in the barrel member and open position wherein the rigid cap member is movable to a position wherein the distal end of the opening is exposed. A releasable latch member is provided to engage and release opposed ends of the radially-openable barrel member.

US Classification:

2271791, 2271751

Abstract:

Introducers for introducing a surgical circular stapler into a patient. Various embodiments comprise cover members that are applied over a stapling head portion of the circular stapler. In some embodiments, the cover members are fabricated from a flexible stretchable material and have a bumper portion that protrudes distally beyond the distal face of the stapling head. The staples may be fired through the cover member and the balance of the cover member is withdrawn from the patient with the stapling head. Other cover embodiments are selectively movable from a position wherein the distal face of the stapling head is covered and other positions wherein the distal face of the stapling head is exposed.

International Classification:

A61B 18/18

US Classification:

606 33

Abstract:

An electrosurgical device comprises an end effector, a cutting member, and en electromechanical driver. The end effector comprises a pair of jaws that clamp tissue. The jaws include electrodes that deliver RF energy to clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical driver drives the cutting member. A control module commands the electromechanical driver, and regulates the delivery of RF energy to the electrodes, based on a combination of user input and feedback signals from the electrodes and from the electromechanical driver. The device may provide tactile feedback to the user through the user input feature, based on a load encountered by the cutting member. The device may alert the user when the exterior of end effector makes incidental contact with tissue, to avoid inadvertently burning the tissue. The device may include a removable battery pack to power the electromechanical driver and the electrodes.

International Classification:

A61B 17/00

US Classification:

606 1

Abstract:

A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.
