Embodiment 1

[0080] Example 1 - A slip ring assembly for use with a surgical shaft assembly. The slip ring assembly includes a first connector flange containing a conductor, a second connector flange containing a conductive element in contact with the conductor, and a support member. The second connector flange is rotatable relative to the first connector flange. The support member is configured to apply a load to the second connector flange to maintain contact between the conductor and the conductive element.

Embodiment 2

[0081] Embodiment 2 - The slip ring assembly of Embodiment 1, wherein the conductive element applies pressure to the conductor, and wherein the support member is further configured to maintain the pressure at or above a desired threshold expected threshold.

Embodiment 3

[0082] Embodiment 3 - The slip ring assembly of one or more of Embodiments 1-2, wherein the conductor is a ring conductor.

Abstract

A slip ring assembly is usable with a surgical shaft assembly. The slip ring assembly includes a first connector flange comprising a conductor. The slip ring assembly further includes a second connector flange comprising a conductive element in contact with the conductor, wherein the second connector flange is rotatable relative to the first connector flange. In addition, the slip ring assembly also includes a support member, wherein the second connector flange is sandwiched between the first connector flange and the support member, and the support member is configured to apply a load onto thesecond connector flange to maintain the contact between the conductor and the conductive element.

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 over an initial predetermined time or displacement can be used to assess tissue thickness and adjust the velocity of the 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 includes a first connector flange includi...
