1493 results about "Elbow joints" patented technology

The elbow joint has three different portions surrounded by a common joint capsule. These are joints between the three bones of the elbow, the humerus of the upper arm, and the radius and the ulna of the forearm.

Dental instruments with stress relief

The present invention relates to a unique solution for relieving repetitive stress to dental professionals during the course of a day and is directed to sets of identical instruments, having handles made with varying diameters for grasping, designed to be used interchangeably throughout the day, thus cutting down on the repetitive grasping action through the change of grasp. Therefore, even if a dental professional uses the same type of instrument throughout the day, the hands, wrists and elbows can experience varying rather than repetitive action because the positioning of the hands, wrists and elbows are interchanging throughout the day. The dental instrument may also be ergonomically designed. Additionally, the instrument may also have a vibratory module. Further, a rotator may also be implemented.

Goniometer-based body-tracking device and method

A sensing system is provided for measuring various joints of a human body for applications for performance animation, biomechanical studies and general motion capture. One sensing device of the system is a linkage-based sensing structure comprising rigid links interconnected by revolute joints, where each joint angle is measured by a resistive bend sensor or other convenient goniometer. Such a linkage-based sensing structure is typically used for measuring joints of the body, such as the shoulders, hips, neck, back and forearm, which have more than a single rotary degree of freedom of movement. In one embodiment of the linkage-based sensing structure, a single long resistive bend sensor measures the angle of more that one revolute joint. The terminal ends of the linkage-based sensing structure are secured to the body such that movement of the joint is measured by the device. A second sensing device of the sensing system comprises a flat, flexible resistive bend sensor guided by a channel on an elastic garment. Such a flat sensing device is typically used to measure various other joints of the body which have primarily one degree of freedom of movement, such as the elbows, knees and ankles. Combining the two sensing devices as described, the sensing system has low sensor bulk at body extremities, yet accurately measures the multi-degree-of-freedom joints nearer the torso. Such a system can operate totally untethered, in real time, and without concern for electromagnetic interference or sensor occlusion.

Locking bone plate

ActiveUS20050015089A1Great flexibility of choiceJoint implantsExternal osteosynthesisTibial-plateau-leveling osteotomyEngineering
A bone plate(s) of complex form is provided, particularly suited to tibial plateau-leveling osteotomy and a distal femoral osteotomy. The bone plate has a main longitudinal axis, a bone-contacting bottom side (not shown) and a top side with at least three sets of overlapping holes which communicate through the plate from the top to the bottom side. The sets of overlapping holes define threaded apertures having multifaceted surfaces. When applied to a bone, two sets of such overlapping holes are located so as to lie on opposite sides of an osteotomy site and on the tibial plate; a third is aligned at approximately 60 degrees with the longitudinal axis. The configuration of this complex bone plate vary, depending on the physiology of the patient. An object of the invention is to provide an orthopaedic surgeon greater flexibility of choice in that a threaded peg providing secure fixing can be positioned at any interval along the bone plate, including at its extreme ends or on its elbow.

Prosthetic joints with contained compressible resilient members

In a total knee replacement (TKR), the use of a cushion element provides better wear characteristics than polyethylene (“poly”) alone. Since a metal-on-metal, metal-on-ceramic, or ceramic-on-ceramic articulating surface has better wear characteristics than metal on poly, the invention essentially provides cushioning for metal / ceramic-on-metal / ceramic joint replacements. It also allows the use of elastomers for their cushioning properties rather than their surface wear and tensile strength characteristics. The contained compressible elements could also be used as a cushion below polyethylene components, polyethylene over metal components, unicondylar knee replacements, patellar components, and prosthetic components for other parts of the body, including the hip, elbow, shoulder, wrist, and ankle.

Over-the-needle safety midline catheter

InactiveUS6960191B2Facilitate over-the-needle insertionReduce bleedingGuide needlesInfusion syringesAxillaSyringe needle
A safety, over-the-needle midline catheter, designed generally for insertion distal to the antecubital crease to be threaded proximally to a site just distal to the axilla. An accompanying safety apparatus is employed which permits only proximal displacement of an associated needle cannula into a safety housing. The catheter has an internal lumen of constant diameter and a proximally disposed taper which in conjunction with the constant internal diameter, provides a wall thickness which effectively resists kinking and associated closure of said lumen which might result from bending of an elbow when a portion of the catheter is disposed at the cubital crease. A butterfly is disclosed which has a collet having a superiorly disposed slit and lips associated with the slit which are sufficiently thin and supple to permit the catheter to be separated from the collet (and butterfly) while wings of the butterfly are disposed upon skin of a patient. Apparatus and methods are disclosed for assisting threading the catheter through difficult anatomical pathways.
