Safety overload for direct skeletal attachment
First Claim

1. An apparatus, comprising:
- a first section attachable to a skeletal attachment;
a second section attachable to a prosthetic limb;
a latch configured to rigidly couple the first section with the second section and to release the rigid coupling in response to an overload on the prosthetic limb, wherein the latch comprises a plurality of pins arranged in parallel when the latch is closed; and
a compliance component positioned partially within an interior of the first section and partially within an interior of the second section, such that when the latch releases the rigid coupling in response to the overload, the compliance component provides a tension between the first section and the second section and prevents detachment of the first section from the second section.

Abstract
Systems and methods are disclosed for prosthetic devices. In one embodiment, an apparatus comprises a first section attachable to an abutment screw of a percutaneous implant; a second section attachable to a prosthetic limb; a latch for coupling the first section with the second section, the latch releasable in response to an overload on the prosthetic limb. A compliance component may be positioned between the first section and the second section, such that when the latch releases in response to the overload, the compliance component provides a tension between the first section and the second section.

9. An apparatus, comprising:
-
a first section attachable to a skeletal attachment; a second section attachable to a prosthetic limb; a latch for coupling the first section with the second section, the latch releasable in response to an overload on the prosthetic limb; a compliance component positioned between the first section and the second section, such that when the latch releases in response to the overload, the compliance component provides a tension between the first section and the second section, wherein the latch is released using a solenoid.

10. An apparatus, comprising:
-
a first section attachable to a skeletal attachment; a second section attachable to a prosthetic limb; a clamp configured to rigidly couple the first section with the second section; a clasp coupled to a first portion of the clamp; a latch configured to engage the clasp to cause the clamp to rigidly couple the first section with the second section and to disengage the clasp in response to an overload on the prosthetic limb; and a compliance component positioned between the first section and the second section, such that when the clasp disengages the latch in response to an overload on the prosthetic limb, the compliance component provides a tension between the first section and the second section. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
