Apparatus for securing a first object to a second object, the apparatus comprising: an elongated body having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end, the lumen comprising a first section and a second section, the first section of the lumen being disposed distal to the second section of the lumen, and with the first section of the lumen having a wider diameter than the second section of the lumen; at least one longitudinally-extending slit extending through the side wall of the elongated body and communicating with the lumen, the at least one longitudinally-extending slit having a distal end and a proximal end, with the distal end of the at least one longitudinally-extending slit being spaced from the distal end of the elongated body; and an elongated element extending through the lumen of the elongated body.

A surgical component connecting device, kit, and method are disclosed. The surgical component connective device includes an outer body, a body element, and a support element. The support element is slidably mounted relative to the body element. Two or more surgical component engaging elements provided towards the distal end of the body element, and at least one of the surgical component engaging elements is operably connected to the support element. The two or more surgical component engaging elements have a first state and a second state. The separation of the two or more surgical component engaging elements is greater in the second state than in the first state.

Technologies for monitoring impaction and predicting impaction state during an orthopaedic surgical procedure include one or more impaction sensors that generate sensor data. The surgical procedure includes impaction of an orthopaedic implement such as a surgical instrument or a prosthetic component. An impaction analyzer generates an impaction state prediction with a machine learning model based on the sensor data. The impaction state prediction may include an unseated state, a seated state, and a fracture state. An impaction state user interface outputs the impaction state prediction. A model trainer may train the machine learning model with labeled sensor data.

To remove a damaged acetabular cup attached to the hipbone, applicant positions the cutting surface of a curved cutting blade at the acetabular cup/hipbone interface. The blade mounts to a head. The powered drive shaft of a motor rotates the blade and head. A linkage, part of which may be around the drive shaft, moves longitudinally relative to the drive shaft under surgeon control. The linkage pivots the head and urges the blade into the interface. As the power tool rotates the curved blade and the linkage pivots the blade into the interface, the blade follows the hemispherical contour of the interface. Continued powered rotation of the drive shaft and blade and further pivoting of the blade cuts the cup from the hipbone.

A medical device for delivering an action to an area of a hip joint or its surroundings, inside a human body, is provided. The hip joint of a patient comprises a collum femur and a ball shaped caput femur, being the proximal parts of the femoral bone, and an acetabulum, being a bowl shaped part of the pelvic bone. The medical device comprising; an elongated member, having a length axis along its elongated distribution, comprising a first portion, adapted to enter the body of the patient, and a mechanical element, adapted to be used during an operation in the hip joint or its surroundings, inside the body. The first portion of the elongated member comprises a holding member adapted to hold the mechanical element inside the body of the patient, wherein the first portion of the elongated member have a first portion cross-section area substantially perpendicular to the length axis of the elongated member. The first portion is adapted to pass through a hole, in a bone of the patient, the hole having a hole cross-section area. The first portion cross-section area, is adapted to be smaller than said hole cross-section area. The mechanical element have a functional status, ready to deliver said action inside said body, when held by the holding member inside the body of the patient. The mechanical element is adapted to have a mechanical element cross-sectional area substantially perpendicular to the length axis of the elongated member, substantially larger than the first portion cross-sectional area and adapted to be unable to pass through the hole, when the mechanical element is in the functional status.

Devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display are disclosed.

A method for providing therapy to a patient, the method comprising: providing microfracture therapy to the acetabular cup of the patient, wherein providing microfracture therapy to the acetabular cup of the patient comprises forming at least one hole extending from the acetabular shelf to the cortical bone bed of the acetabular cup, such that blood may flow from the cancellous bone underlying the cortical bone bed to the surface of the cortical bone bed, whereby to form a blood clot at the surface of the cortical bone bed.

A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.

A surgical guide can include a first portion comprising an outer surface configured to conform to a portion of an acetabulum of a particular patient. The first portion can be configured to accommodate the ligamentum teres of the patient. The surgical guide can be configured to receive a second portion that includes an alignment portion defining an alignment axis such that when the surgical guide is coupled to the acetabulum, the alignment axis is oriented at a predetermined orientation relative to the acetabulum. The second portion can include a depth-limiting feature configured to limit insertion of a guide rod along the axis to a patient-specific insertion depth.

A surgical blade (180) designed for use with an acetabular cup remover (30). The blade includes a body (182) from which teeth (190) extend distally forward. The body and teeth are disposed around the section of a sphere. On each side of the longitudinal axis of the blade body there is an outer tooth and at least two inner teeth. The teeth are further shaped so that one each side of the longitudinal axis through the blade body there are at least two adjacent inner teeth that have rake surfaces located along axes that, extending from the outer surface of the blade body to the inner surface of the blade body, do not intersect.
