A broach handle for a rasp includes a proximal part extending along a first axis between a first portion of the handle and a second portion of the handle, and a proximal part extending partially along a second axis between a third portion of the handle, connected to the second portion, and a fourth portion of the handle, and partially along a third axis between a fifth portion of the handle, connected to the fourth portion, and a sixth portion of the handle connectable to a rasp. The sixth portion of the handle has a connection surface for connecting to the rasp having a normal extending along a normal axis defining a connection axis between the handle and the rasp. A first convex angle is defined between the first axis and the second axis, and a second convex angle is defined between the third axis and the normal axis.

A device for tensioning a surgical thread comprising: an elongated body having a tip portion adapted to be arranged in contact with a knot of a surgical thread wound about a patient's bone and a maneuvering member connected to the elongated body by a screw and nut mechanism configured to adjust the distance between said elongated body and said maneuvering member, said maneuvering member having respective coupling portions for coupling opposite ends of the surgical thread wound and knotted about the bone. The opposite ends of the surgical thread reversibly constrainable to the respective coupling portions in a use configuration of the device. The distance between the elongated body and the maneuvering member can be increased along a movement axis to tension the opposite ends so as to tighten the surgical thread about the bone. The tip portion has a groove shaped to receive at least partially the knot.

A femoral component and a tibial component are respectively configured to exclusively couple with the distal end of a femur bearing a femoral prosthesis and with the proximal end of a tibia bearing a tibial prosthesis. The femoral component has a distal portion configured to face the distal end of the femur, bearing distal positioning holes facing a distal region of the femoral prosthesis. A frontal portion extends on the continuation of the distal portion and has a first abutment area operating against the femur bone part and a second area facing a frontal region of the femoral prosthesis. The frontal portion has at least two guide holes at the first abutment area, and at least two frontal positioning holes at the second area.

Various implementations include a positioning device of a surgical instrument for hip arthroplasty surgery that includes an arched structure having a first and a second end, wherein the first end can be positioned inside a patient, a gripping element located at the second end of the arched structure, a surgical instrument that can be coupled to the gripping element at a seat made in this gripping element, and a positioning and fixing head arranged at the first end of the arched structure.

A patient limb positioning apparatus comprises a movement assembly operating on a coupling bracket which can be engaged with the patient's limb, to move the limb according to a plurality of axes of movement. The movement assembly comprises, for at least one of said axes of movement, a drive unit which can be activated to move the coupling bracket according to a predetermined direction of movement. A load transducer detects a load transmitted between the coupling bracket and the drive unit in the respective direction of movement, to emit a signal representative of a detected load value. An electronic control unit is selectively switchable to a load control command mode and is suitable to cyclically compare the measured load value with a pre-set load value, to control activation of the drive unit when the detected load value differs from the pre-set load value.

Positioning apparatus of a patient's limb

A computer-implemented method for checking the correct alignment of a hip prosthesis, includes: detecting a 3D model of the pelvic bone of a patient in a preoperative phase, detecting at least one 2D image of the pelvic bone in post-implant situation, selecting an image of the 3D model according to a first inclination thereof and detecting a reference element on said selected image of the 3D model, identifying a plurality of reference points on the 2D image, superimposing the 2D image on said selected image of the 3D model, checking the correct superimposition and correspondence of the reference points of the 2D image with the reference element with said image of the 3D model, and detecting possible differences in the positioning of the pelvic bone in post-implant configuration with respect to the preoperative situation.

Handle of a medical tool

An adapter plane for a surgical table comprising a central body having a proximal portion suitable to at least partially accommodate the lumbar region of the body of a patient and a distal portion suitable to at least partially accommodate the sacral region of the body of a patient, wherein the adapter plane can be coupled to a surgical table by placing the central body at least partially on top of the surgical table, and the central body, in the distal portion, is provided with a quick coupling device for coupling the adapter plane to one or more surgical instruments.

A bone resection instrument, comprising means of support and positioning for the correct alignment of the tool with respect to the bone to be cut, a cutting guide, connected to the means of support and positioning, comprising a support attachable to a bone to be cut. The cutting guide comprises a gauge block having a cutting surface and removably connected to said support. The instrument is part of a bone resection kit comprising a plurality of gauge blocks, each differing in height from one another.
