Disclosed is a surgical instrument that comprises a handle, a trigger pivotably coupled to the handle, wherein the trigger is movable between a first position and a second position. The surgical instrument further comprises a shaft extending from the handle, wherein the shaft comprises a distal end forming a hook. The surgical instrument further comprises a clamp arm extending from the handle and mechanically coupled to the trigger, wherein movement of the trigger from the first position toward the second position moves the clamp arm toward the hook. The surgical instrument further comprises a ratchet mechanism mechanically coupled to the clamp arm, wherein the ratchet mechanism is configured to prevent movement of the trigger toward the first position at incremental positions between the first position and the second position.

The present invention relates to a cable pulling device (1) for orthopedic bone transport, comprising: a main body (2); a worm gear mechanism (4) disposed in the main body (2), and a reel (8) set into rotation by the worm gear mechanism (4) and meant to wind up a cable which is secured to a transport bone segment.

A surgical ring and related methods for plantar plate reconstruction and other surgical procedures are described. In particular, the described anchoring systems and surgical methods may include an anchor configured to wrap at least partially around a first bone associated with an affected joint, and wrap at least partially around a tissue alongside the first bone. The anchor may be compressed in a number of ways so as to compress the tissue alongside the first bone against the first bone. The anchor may be formed from a compressible material, configured with an open shape, and/or or include mechanically closeable or compressible features, and the like. The anchor may be formed from various materials including non-bioabsorbable, bioabsorbable, and/or superelastic materials. The first bone may be a metatarsal or phalanx and the tissue alongside the first bone may be a ligament, a plantar plate, or similar tissue.

The present invention provides a tensioning ancillary instrument (5) for tensioning an elongate element to fasten an implant on a portion of bone, by surrounding said portion of bone at least in part, said instrument (5) comprising a body (6) having proximal and distal ends (6a, 6b), the distal end (6a) being provided with a device for bearing against the implant, said body (6) extending along a longitudinal axis (L). The instrument (5) further comprising a carriage (7) that is movable along the longitudinal axis (L), and a fastener device (8) for fastening to the elongate element (2). The instrument (5) also includes a rotary shaft (9) rotatable about the longitudinal axis (L) of the body (6), the shaft (9) being configured to co-operate with the carriage (7) in such a manner that rotation of the shaft (9) drives movement of the carriage (7) in translation along the longitudinal axis (L) and correspondingly moves the carriage (7) away from the distal end (6b) of the body (6) and tensions the elongate element.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.

Various systems and methods for treating the spine are provided. A portal system can be provided for treating the spine. The portal system can include a portal comprising a proximal end and a distal end, a first passageway extending between the proximal end and the distal end, a second passageway extending between the proximal end and the distal end, and a latch. The bone tie can include a head, a body section comprising one or more gears, and a fastener section comprising a ratchet.

A device for bending a kirschner wire comprises: a retaining slot for fixing a kirschner wire, with a contact for applying a bending force to a steel needle fixed by the retaining slot being disposed at a lateral of the retaining slot. Compared with the prior art in which clamping heads are used to clamp a steel needle first and then the steel needle is forcibly bent in the clamped state in most cases, which may be time-consuming and strenuous, the present invention provides not only a device for bending and chipping off an orthopedic steel needle in one time, which is applicable to cases where chipping off of steel needles is required, but also a device capable of only bending a steel needle, which is low in requirement on material and low in manufacturing cost as the force for bending a steel needle is far smaller than the force for chipping off the same, and thus is applicable to cases where only bending of steel needles is required.

A bone fixation assembly may include an elongate fixation member and a flexible tensioning element. The elongate fixation member may include a central longitudinal axis, a distal portion couplable to a first bone fragment of a bone, and a proximal portion couplable to a second bone fragment of the bone to provide fixation of the second bone fragment relative to the first bone fragment. The flexible tensioning element may be couplable to the proximal and distal portions of the elongate fixation member to secure the elongate fixation member to the bone. The flexible tensioning element may be configured to span a bone fracture intermediate the first bone fragment and the second bone fragment to preload the bone fracture in compression to resist tensile force imparted across the bone fracture, thereby maintaining fixation of the first bone fragment relative to the second bone fragment.
