International Classification:

A61B 17/072

Abstract:

A surgical stapling system can include a reload shaft. The shaft can include an elongate tubular member with have a jaw assembly at the distal end thereof and a coupling collar at the proximal end thereof. The shaft assembly also includes an articulation joint coupling the jaw assembly to the distal end. A drive member and an articulation member extend within the tubular body of the shaft from the proximal end to the distal end. A firing member is connected to the distal end of the drive member such that advancement of the drive beam advances the firing member to close the jaw assemblies and fire staples from a reload positioned in the jaw assembly. The shaft assembly can also include a lockout mechanism to prevent a firing operation on a previously-fired reload or no reload.

International Classification:

A61B 17/072
A61B 17/29
H02J 7/00

Abstract:

A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.

- Rancho Santa Margarita CA, US
Andrew J. McCarthy - Trabuco Canyon CA, US
Babak D. Jasemian - Trabuco Canyon CA, US

International Classification:

A61B 17/072

Abstract:

A handle assembly for a surgical stapler can comprise a rotatable actuation shaft. The actuation shaft can have a first rotational orientation in which it can actuate a jaw assembly in a repeatable open and close mode, a second rotational orientation in which it can actuate a jaw assembly in a staple firing mode, and a third rotational orientation in which it can actuate a jaw assembly in a reversing mode. The handle assembly can include an articulation mechanism including a ball screw to selectively articulate the jaw assembly relative to an elongate shaft.

International Classification:

A63B 53/06
A63B 60/02
A63B 60/52
A63B 53/04

Abstract:

A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.

Abstract:

A golf club head includes a club head body and a weight member that is secured to the body in a weight mount. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member. The weight member includes a spring feature that is movably coupled to a weight body so that it is movable between a first configuration and a second configuration. In the second configuration a portion of the spring feature extends outward from a side wall of the weight body. The weight mount includes an undercut and the spring feature extends into the undercut and is partially flexed by the abutment of the spring feature and a perimeter wall of weight mount when the weight member is disposed in the weight mount.

International Classification:

A61B 17/10
A61B 17/00
A61B 17/128
A61B 17/00

Abstract:

A laparoscopic clip applier can have a geared clip feed mechanism and a direct jaw clamping mechanism to provide smooth operation over a clip application stroke of a movable handle. The geared clip feed mechanism can include an idler gear and two drive gear racks to advance a feed slider feeding a clip to a jaw assembly. The two drive gear racks can be positioned to provide different gearing during clip feed and firing portions of the clip application stroke, allowing efficient packaging of the clip feed mechanism. A spring can rapidly withdraw the feed slider once the clip has been fed and before clamping begins. The movable handle can have a direct connection to a clamping slider to enhance user feedback during clamping of the clip. After clamping the clip, the movable handle can also assist in returning the clamping slider to an initial position for firing another clip.
