摘要: Various implementations include an alignment device for carrying out a periacetabular osteotomy operation on a patient that includes
a patient-specific acetabular unit, to be fixed in a univocal position on the iliac bone, in proximity of the acetabulum;
a patient-specific iliac unit, to be fixed in a univocal position on the iliac bone, in a lateral position with respect to the acetabular unit; and
a patient-specific bridge, to be connected in a rigid and univocal manner to the acetabular unit and to the iliac unit.
The acetabular unit and the iliac unit assume a first mutual position incompatible with the bridge. When osteotomy is carried out and the bridge is connected to the acetabular unit and the iliac unit, they assume a second position, different from the first position and corresponding to a bio-mechanically correct position of the acetabulum with respect to the remaining portion of the iliac bone.-

摘要: Various implementations include a cutting tool for the horizontal incision of tendons. The tool comprises a stem extending along a longitudinal axis, having a distal end, a proximal end and a cutting head, located close to said distal end, having a base plate, having a longitudinal extension axis parallel to the longitudinal axis of the stem, and a blade extending on a plane parallel to the base plate. The blade has a plurality of cutting edges inclined with respect to the longitudinal axis of the cutting head according to different angles, so as to identify at least two vertices defined by two V-shaped profiles.

摘要: Various implementations described herein relate to a minimally invasive auxiliary tool for knee surgery. The tool comprises a handle in proximal position, a shaft defining an axis, and a shaped tip in distal position. In the tool: the handle, the shaft, and the shaped tip define a channel that connects the proximal end with the distal end of the tool; and the perimeter of the shaped tip comprises a plurality of sectors, wherein each sector is defined by a respective circular arc centred on the axis and wherein the circular arcs that define the various sectors have respective radii that are different the one from the others. Various implementations also include a kit comprising a tool and a bone reamer.

摘要: A device for the retraction of soft tissue in a patient undergoing arthroscopic surgery, comprising a pulling element extending in its own main direction between a first end and a second end, the latter being fitted with a hooking body configured to pass through the soft tissue of a patient and engage in the soft tissue following the traction of the pulling element towards the first end. The device further comprises a presser body suitable to press on the skin of the patient and connectable to the pulling element in at least one operating position placed at a fixed distance from the second end, wherein the fixed distance is such as to define a housing for the layers of soft tissue of the patient engaged by the hooking body.

摘要: An arthroscope comprises a sleeve having an internally hollow, proximal portion and an internally hollow middle portion connected to the proximal portion so as to create a through axial cavity. The sleeve has, within the middle portion, an abutment area. The arthroscope also comprises an optical unit having an elongated portion and a coupling portion configured to be at least partially received inside the through axial cavity of the sleeve. The coupling portion has a matching area suitable to couple with the abutment area. The matching area and the abutment area are shaped so as to have at least one pilot element so as to determine a univocal predefined coupling position between the sleeve and the optical unit; the matching area and the abutment area are also shaped so as to guide and automatically place the optical unit in such a predefined position.

摘要: A cutting tool for the vertical incision of tendons comprising a shaft extending along a longitudinal axis, having a distal end and a proximal end, and a cutting head, located close to said distal end, having a plurality of blades. The cutting head lies on a plane parallel to the longitudinal axis of the shaft and is connected to the latter by a coupling inclined with respect to the longitudinal axis by an angle from 10° to 20°, preferably of 15°.

摘要: A template for measuring the cross section of a graft comprises a first half-body and a second half-body. The two half-bodies are mutually secured such that they can rotate the one with respect to the other around an axis, each one of the two half-bodies comprises a plurality of openings having known and different sizes, each one of the openings of the two half-bodies is open toward the outside through an at least partially radial slot. The two half-bodies can rotate the one with respect to the other around the axis between an open position and a closed position and vice versa. In the open position the slots of the first half-body axially coincide with the slots of the second half-body, and in the closed position the openings of the first half-body axially coincide with the openings of the second half-body.
