Instruments and methods for surgical transosseous attachment to a bone include a guide able to guide the formation of intersecting bone tunnels and a passer able to pass a member through the bone tunnels.

A flexible reamer for preparing a hole in a tissue includes a shaft that extends along a longitudinal axis between a proximal end and a distal end. The shaft is cannulated through and has a flexible portion along at least a portion of its length. The flexible portion includes a plurality of discrete, interlocking portions. An asymmetric tip at the distal end of the shaft has at least one flute positioned off-axis relative to a longitudinal axis of the flexible reamer.

In a first embodiment, the present invention includes an instrumentation system for preparing a bone for soft tissue repair, the instrumentation system including a flexible drill pin capable of bending along a curved path; an aimer capable of engaging the flexible pin to bend the flexible pin; and a flexible reamer having a flexible portion along at least a portion of its length, the flexible portion comprising a plurality of laser cuts. In an alternate embodiment, the present invention may also include a method for preparing a bone tunnel in a femur adjacent a knee joint, the method including introducing a flexible drill pin into the knee joint; guiding the flexible drill pin towards a surface of the femur with an instrument introduced into the knee joint; drilling the flexible drill pin into the femur; removing the instrument from the knee joint; introducing a cannulated flexible reamer into the knee joint by placing the flexible pin within the cannulation of the flexible reamer; and reaming the bone tunnel in the femur along the path of the flexible pin.

The invention concerns a perfected device for the transosseous insertion of suture threads. This device comprises a main body (1) supporting a protruding cannula (3) provided with an active end (30); the device comprises a flexible threadlike element (4), on which there are fashioned a sharp tip (40) and an opening (41) that serves for the threading of at least one suture thread (5), said element (4) being housed in a coaxially sliding manner inside said cannula (3) and, on command, exiting from the active end (30) of the cannula, assuming a curved position; the device comprises first means for producing the coaxial movement of the threadlike element (4) in the two directions with respect to the cannula (3) and second means for producing a coaxial movement of the threadlike element in the exiting direction from the cannula (3); for a short tract, the movement produced by the second means is disengaged from the advancement of the threadlike element produced by the first means.

The present invention includes a method and devices for treating osteonecrosis in, e.g., children, adolescents, and adults comprising: identifying a subject in need of treatment for osteonecrosis; drilling two or more holes into a bone in need of treatment for osteonecrosis; inserting two or more needles or cannulas into the holes in the bone; washing an interior of the bone with a washing fluid introduced through one or more of the needles or cannulas inserted into the bone; and after washing the interior of the bone introducing one or more bone growth promoting materials or cells into the bone.

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.

A kit (4000, 5100) including a guiding system and a cannulated bone material removal device, the bone material removal device (4004, 5200) having a longitudinal shaft (4024, 5202) and comprising on the longitudinal shaft a radially expandable cutting portion (4028, 5208) having a longitudinally-oriented cutting edge (2124), the radial expansion comprising an increase of a cross-sectional diameter of the bone material removal device at the longitudinal position of the expandable cutting portion; and the guiding system including an arcuate element (4008, 5102), a guiding element (4010, 5104) configured to be attached to the arcuate element, and a cannula (4002, 5106), slidably insertable into a portion of the arcuate element; wherein the bone material removal device is axially displaceable within said cannula. The kit can be used in anterior cruciate ligament (ACL) reconstruction.

Drill guides are disclosed herein that allow an implant to be partially inserted after the holes are drilled and before the drill guide has been removed from the surgical location.

A flexible bone tool including a plurality of links pivotly coupled to each other and collectively define a substantially tubular, bendable body coupled (a) at a proximal end to a holding portion and (b) at a distal end to a bone tissue removing element. The plurality of links includes one or more proximal links having an engaging portion, a wall of which comprising a first aperture and one or more distal links comprising a receiving portion, a wall of which comprising one or more second apertures, the receiving portion being sized and fitted to receive the engaging portion such that the first and second apertures are aligned and at least one pin sized and fitted to be received by the aligned first and second apertures and pivotly couple said proximal and distal links.

A guide pin piercing jig includes a curved frame, a front cylinder unit provided at a front end of the frame, and a rear cylinder unit provided at a rear end of the frame, in which the front cylinder unit has a positioning projection and a boring aiming portion at a tip thereof, the rear cylinder unit has a plurality of parallel guide pin insertion cylinders into which to insert the guide pins and a tentative fixing unit provided at a tip of the rear cylinder unit, and the rear cylinder unit is provided at a rear end of the frame slidably so as be directed to a tip of the front cylinder unit. It becomes possible to aim at a proper portion of a living body bone through which to bore a bone tunnel and to pierce the living body bone with guide pins for hollow drills from behind the living body bone to the proper aiming portion in a proper direction.
