Abstract
A force sensor arrangement for use in a surgical device includes a support block supported within the surgical device and defining a support block surface; a load sensor disposed axially adjacent the support block, the load sensor defining a sensor surface; and a spherical disc interposed between the support block and the load sensor, and in contact with the support block surface and the sensor surface, wherein the spherical disc defines a first side in contact with the sensor surface, and a second side in contact with the support block surface, wherein the second side of the spherical disc has a spherical profile and the support block surface has a complimentary spherical profile.

A force sensor arrangement for use in a surgical device, the force sensor arrangement comprising:
- a support block supported within the surgical device and defining a support block surface;
- a load sensor disposed axially adjacent the support block, the load sensor defining a sensor surface;
- and
- a spherical disc interposed between the support block and the load sensor, and in contact with the support block surface and the sensor surface, wherein the spherical disc defines a first side in contact with the sensor surface, and a second side in contact with the support block surface, wherein the second side of the spherical disc has a spherical profile and the support block surface has a complimentary spherical profile.
A force sensor arrangement for use in a surgical device, the force sensor arrangement comprising:
- a support block supported within the surgical device and defining a support block surface having a support geometric profile;
- a load sensor disposed axially adjacent the support block, the load sensor defining a sensor surface having a sensor geometric profile;
- and
- a disc interposed between the support block and the load sensor, and in contact with the support block surface and the sensor surface, wherein the disc defines a first side in contact with the sensor surface and having a first geometric profile, and a second side in contact with the support block surface and having a second geometric profile;
- wherein at least one of the first geometric profile or the second geometric profile is complementary to the corresponding at least one of the support geometric profile or the sensor geometric profile;
- wherein the first geometric profile and the second geometric profile include a spherical surface.
A force sensor arrangement for use in a surgical device, the force sensor arrangement comprising:
- a support block defining a support block surface and a support block passage having a longitudinal axis;
- a load sensor disposed axially adjacent the support block, the load sensor defining a sensor surface and a load sensor passage extending along the longitudinal axis;
- and
- a spherical disc interposed between the support block and the load sensor, and in contact with the support block surface and the sensor surface, wherein the spherical disc defines a first side in abutting contact with the sensor surface, and a second side in abutting contact with the support block surface, wherein the second side of the spherical disc has a spherical profile and the support block surface has a complimentary spherical profile whereby the spherical disc is free to pivot relative to the longitudinal axis to maintain the support block and the load sensor in force transmitting alignment with one another, and wherein the spherical disc defines a spherical disc passage extending along the longitudinal axis.
