Surgery instruments with a movable handle
Various surgical tools having a movable handle mechanism including a positioning handle are disclosed. The movable handle mechanism may be configured to move forward and backward in a longitudinal direction along the housing and rotate clockwise and counterclockwise around the housing. In various embodiments, the housing may include a plurality of channels and each channel may have at least one detent. The movable handle mechanism may be configured to securely couple to the housing via one channel of the plurality of channels and one detent of the plurality of detents. At least one surgical tool may include a drill having an angled tip portion and a sleeve configured to protect adjacent structures from lateral edges of the drill bit when the drill bit is rotating. Another surgical tool may include a screwdriver having an elastic retaining clip configured to progressively release a bone screw therein at an extraction force.
Suture based clamping device
Systems, assemblies, and methods are provided herein for fastening of one bone to another bone using one or more sutures. The features herein enable such fastening with a more accurate strength, and which can be more easily fastened in-situ.
Orthopedic implant and methods of implanting and removing same
Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.
Surgical instrument and method
A surgical instrument having a first member engageable with a first end of a fastener having a second end configured to penetrate tissue. A second member includes an expandable member configured for engaging the first end. Systems and methods are disclosed.
EXPANDABLE INTER-BODY DEVICE, SYSTEM, AND METHOD
Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.
ORTHOPEDIC SCREW EXTRACTOR
An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.
IMPLANTABLE COMPRESSION SCREWS
A compression screw for applying compression at a bone joint. The compression screw includes an axial screw body extending from a distal end to a proximal end with the distal end including a series of bone engaging threads configured to be self-drilling and self-tapping and the proximal end including a head which defines a radially extending shoulder. At least one proximal rotary cutting structure is defined proximally of the bone engaging threads. The at least one proximal rotary cutting structure is configured to be self-drilling such that a proximal portion of the axial screw body cuts into and advances within a bone of the bone joint as the axial screw body is advanced. A method of inserting the compression screw is also provided.
Miniaturized dual drive open architecture suture anchor
The disclosure provides examples of an open architecture anchor for securing soft tissue to bone, for example, to repair a torn rotor cuff. The anchor includes at least one open helical coil defining a polygonal internal volume and at least one rib disposed within the polygonal internal volume and connected to at least two turns of the at least one open helical coil. The at least one rib is sized to engage a driver and a combination of the at least one rib and the polygonal internal volume is sized to provide an anchor drive torque required to drive the anchor into bone.
Medical Screw
A dual drive screw that includes a head and a shaft. The head has a top surface, a first recess in the top surface comprising a first drive and a second recess below the first recess comprising a second drive. The shaft extends from the head opposite the top surface and includes an exterior surface with a thread formed on at least part of the exterior surface. The first drive may be a star drive, a hex drive, a square drive, a 12-point flange, a double square, a double hex, a spline drive or any other drive that has an opening large enough for a device to pass through and engage the second drive in the second recess. A first device engages the first drive and rotates the screw in a clockwise direction. A second device engages the second drive and rotates the screw in a counter-clockwise direction for removal. The dual drive screw is preferably implanted in a person.
BONE SCREW
The invention relates to a surgical instrument comprising a bone screw having a screw head, and a shaft for rotating the bone screw in a bone, the shaft and/or head forming a single element with the bone screw and having a predetermined breaking point. A driving element is inserted into the bone screw by the shaft, said driving element screwing the screw further in or out once the shaft has broken off from the screw.
