Embodiment 1

[0100] Embodiment 1 - A slip ring assembly for use with a surgical shaft assembly, the slip ring assembly comprising a first housing portion, a first connector supported in the first housing portion, and a first connector mounted on the The first conductor on the first connector. The slip ring assembly also includes a second housing portion, a connector supported in the second housing portion, and a second conductor mounted on the second connector. The second housing part is rotatable relative to the first housing part. The second conductor is in contact with the first conductor. The slip ring assembly further includes an interface between the first housing portion and the second housing portion, wherein the interface is configured to allow connection between the first housing portion and the second housing portion. A seal is achieved between the second housing parts.

Embodiment 2

[0101] Embodiment 2 - The slip ring assembly of Embodiment 1, further comprising a resilient member configured to apply a load to the second housing portion to maintain the seal.

Embodiment 3

[0102] Embodiment 3 - The slip ring assembly of one or more of Embodiments 1-2, wherein the resilient member is a spring coupled to the second housing portion.

Abstract

The present invention discloses a slip ring assembly. The slip ring assembly is used with a surgical shaft assembly. The slip ring assembly includes a first housing portion, a first connector supported in the first housing portion, and a first conductor mounted on the first connector. The slip ring assembly also includes a second housing portion, wherein one of the first housing portion and the second housing portion is rotatable relative to the other, a second connector supported in the second housing portion, and a second conductor mounted on the second connector, wherein the second conductor is in contact with the first conductor. An interface between the first housing portion and the second housing portion, wherein the interface is configured to effect a seal between the first housingportion and the second housing portion.

Description

technical field [0001] The present disclosure relates to surgical instruments, and in various cases, to surgical stapling and cutting instruments and cartridges thereof designed for stapling and cutting tissue. Background technique [0002] In motorized surgical stapling and cutting instruments, it may be useful to measure the position and velocity of the cutting member for an initial predetermined time or displacement to control the velocity. Measurement of position or velocity within an initial predetermined time or displacement can be used to assess tissue thickness and adjust the velocity of remaining travel based on this comparison to a threshold. [0003] While several devices have been developed and used, it is believed that no one prior to the present inventor has developed or used the device described in the appended claims. Contents of the invention [0004] In one aspect of the present disclosure, a slip ring assembly is used with a surgical shaft assembly. Th...
