Publication number: 20220273390Abstract: A force limiting apparatus for a surgical instrument to prevent too much force being applied to the jaws of the instrument. The instrument has a body with a drive shaft coupled to a pair of jaws, a bearing tube secured to the drive shaft, and a pair of tracks carrying a pivot pin that is biased into one end of the track. A lever is coupled to the pivot pin and abuts the bearing tube to move the bearing tube and close the jaws when squeezed by a user. If the lever is over actuated, the pivot pin will slide along the track against the bias of the spring assembly with the lever pivoting about the bearing tube rather than the pivot pin. As a result, the additional movement of lever does not result in any addition force being transmitted to the drive shaft via the bearing tube.Type: ApplicationFiled: July 28, 2020Publication date: September 1, 2022Applicant: Conmed CorporationInventors: Mason Williams, Michael L. Koltz, JR.

Patent number: 11419597Abstract: Methods and devices for securing soft tissue to a rigid material such as bone. A tissue capture anchor is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and spreader and inside surfaces of a bone hole to secure the tissue within the hole. A bone anchor is described that comprises an anchor body with expandable tines and a spreader that expands the tines into bone. The spreader captures tissue via a suture loop at the distal end of the bone anchor. Also described is an inserter that can be used to insert the anchor into bone and move the spreader within the anchor to expand the anchor and capture the tissue between the anchor and the bone. Methods are described that allow use of single bone anchor to secure tissue to bone or also to use more than one bone anchor to provide multiple lengths of suture material to compress a large area of soft tissue against bone.Type: GrantFiled: October 26, 2017Date of Patent: August 23, 2022Assignee: Conmed CorporationInventors: Malcolm Heaven, Michael Ko, John P.
