Intramedullary fixation device

Intramedullary fixation device, having an intramedullary rod (2) which is provided for insertion thereof into a bone (1) and consists of a central screw (4) having a first free end comprising a stopper (7) and a second free end with a pre-tensioning nut (8), an alternating series of expanders (3) and bolts (5) being arranged in between, the bolt surfaces in contact with the expanders (3) having a wedge shape. The bolts (5) or expanders (3) may have no, or one or more variations in the dimensions of the different geometric parameters, in accordance with the adjacent expanders, along the length of the implant, and the central screw (4) may have a variable cross section. The device may have different additional components, such as an osteotomic base (9) for fixation of the musculature. The device promotes maximum nailing limited between these elements and produces a controlled peripheral radial deformation.

Non-snag prosthetic foot and leg
10568750 · 2020-02-25 · ·

The present disclosure illustrates a prosthetic foot that may reduce snagging on external obstacles. In some embodiments, a prosthetic foot includes a symmetric wear member that is rotatable to allow a user to alter an orientation of the symmetric wear member for even wear. A cuff may couple to the symmetric wear member, and include the proximal end comprising a receptacle with an opening having an adjustable diameter. The receptacle may be sized and shaped to receive and selectively retain the prosthesis pylon by adjusting the diameter of the opening. The prosthetic foot may further include a vertical adjustment mechanism that selectively alters a depth of the receptacle of the cuff to vertically displace the prosthesis pylon.

A method and an osseointegrated prosthesis system having an osseointegrated prosthesis member are provided having a monitoring system operably coupled to the osseointegrated prosthesis member configured to quantitatively assess the osseointegration of the osseointegrated prosthesis member, a wave-generating element coupled to the osseointegrated prosthesis member and configured to output guided waves along the osseointegrated prosthesis member interrogating an interface between bone and the osseointegrated prosthesis member, and a sensing system configured to sense a condition of the interface between bone and the prosthesis.

TRANSCUTANEOUS IMPLANT FOR SKELETAL ATTACHMENT OF EXTERNAL PROSTHETIC DEVICES
20190374354 · 2019-12-12 ·

Provided herein are devices and methods for connecting a transcutaneous external prosthetic device to a bone, such as a bone of an amputee. The device is a two-piece transcutaneous implant device to provide reversible connection for ease of implantation, reliability, and relatively easy access for removal, while maximizing tissue ingrowth to reduce risk of infection and attendant adverse outcomes. The devices provided herein comprise a prosthetic interface and a bone anchor. A through-hole that traverses a longitudinal length of the prosthetic interface and at least a longitudinal portion of the bone anchor receives a fastener to reversibly connect the prosthetic interface to the bone anchor implanted in bone. A connector may connect to a failsafe element which, in turn, connects to an external prosthetic device.

ELECTRODE ARRANGEMENT FOR PLASMA TREATMENT AND DEVICE FOR PRODUCING A TRANSCUTANEOUS CONNECTION

A transcutaneous connection between an exterior and an interior of a human or animal body includes a cylindrical skin penetration piece which provides a passage through the skin and has a longitudinal axis that determines the direction of passage through the skin. Wound-healing action and reliable disinfection are effected using an annular flat electrode arrangement, which has a contact surface at an angle to the longitudinal axis, can be fastened to the skin penetration piece. The electrode arrangement includes a flat electrode and a flat dielectric shielding the electrode relative to the surface of the skin, and is designed as a counter-electrode to generate a dielectric barrier plasma between the dielectric and the surface of the skin.

DEVICE FOR THE EXO-PROSTHETISATION OF LIMBS AND OTHER PERCUTANEOUS APPLICATIONS

A percutaneous collar is made up of a central rigid ring and a flexible mesh inside a microporous silicone disc. The volume of the disc has a three-dimensional network of interconnected micropores forming microchannels connecting both external faces of the disc through the external micropores to the internal flexible mesh wherein the flexible mesh is formed by crossed longitudinal and radial elements or plates which form a plurality of holes.

Osseointegrable device

An implant arranged for integration into a skeletal bone of a patient, comprising: a body having at least one end, the body being arranged to substantially mimic a portion of a skeletal bone; wherein the at least one end includes an enlarged portion arranged to, in use, prevent migration of the implant into the flesh of a patient.

Artificial finger

An artificial finger for prosthetics and gripping technology, with a base, a first finger member mounted on the base in articulated manner, at least one secondary member mounted on the first finger member in articulated manner, and a drive for adjusting the secondary member relative to the first finger member and the first finger member relative to the base. At least one reset element is provided for resetting the first finger member and the secondary member, and the first finger member is acted upon with a resetting force which differs from the secondary member.

SECURING ARRANGEMENT FOR A PROSTHETIC HAND ON A FOREARM SHAFT AND PROSTHESIS SYSTEM

A securing arrangement of a prosthetic hand on a forearm socket with a receiving frame that can be fixed to the forearm socket, the prosthetic hand being fixed to said receiving frame, wherein the receiving frame is designed to feature radially-directed openings, through which the securing elements protrude. The securing elements positively engage with a proximal connection section of the prosthetic hand.
