A medical device, comprises an elongated member having a first end portion and a second end portion opposite the first end portion. A handle is coupled to the elongated member at the first end portion and defines a first striking surface. A second striking surface is coupled to the elongated member between the first end and the second end as a protrusion extending away from the elongated member. A hook is coupled to the second end portion and defines a channel sized and configured to receive at least a portion of a surgical implant.

The present invention provides a supporting hook structure, comprising a sleeve, a fixing rod, a first limit unit, a hook and a fixing device. The fixing rod is connected to the side surface of the sleeve. The hook body is connected to one end of the sleeve. The first limit unit is arranged on the side surface of the sleeve and adjacent to the hook body. The first limit unit makes the hook body rotates with the axis direction of the sleeve as a rotation axis. The fixing device is connected to the other end of the sleeve to fix the rotating position of the hook body. Through the above, the hook part enters the proximal thigh from a surgical entrance and the hook part rotates to make the hook part abut against the proximal femur to complete the positioning and fixation of the femur hook structure to the femur.

The invention provides a femoral head centre of rotation locating device (10) comprising an adjustable frame (12) having a frame axis (X). The frame includes a central frame portion (14); a first jaw (16) that is linearly moveable relative to the central frame portion along the frame axis and having a first femoral head contacting surface (26); a second jaw (18) that is linearly moveable relative to the central frame portion along the frame axis and having a second femoral head contacting surface (28), and a gear wheel (32) mounted on the central frame portion. The gear wheel has a centric aperture (34) located substantially equidistant from the first and second femoral head contacting surfaces. The gear wheel is operably connected to each of the first and second moveable jaws by gear teeth (30) provided on a surface of each of the first and second moveable jaws. Linear movement of the first jaw in a first direction rotates the gear wheel to cause reciprocal linear movement of the second jaw to maintain the centric aperture at a position equidistant from the first and second femoral head contacting surfaces. This aligns the centric aperture with the native head centre of the femur as the first and second femoral head contacting surfaces come into contact with opposite surfaces of the femoral head.

A surgical tool for separating two components, for example removing a femoral head from a femoral stem, having a four bar chain whose four bars are a first handle (L1), an crossover component (L2), a second handle (L3) and a crossbar (L4) pivotally connected respectively by: a first joint (J1) between the first handle and the crossover component; a second, crossover joint (J2) between the crossover component and the second handle; a third joint (J3) between the second handle and the crossbar, and a fourth joint (J4) between the crossbar and the first handle, and wherein, upon application of a gripping force to the first and second handles, the first and second jaws separate from one another so as to separate the two components engaged therewith.

An orthopaedic surgical instrument may include an elongated body with a broach end and an impactor end. The body may be straight or curved. A latch lever may be pivotally coupled to the elongated body. The latch lever may be moveable between an open position and a latched position in which the latch lever is retained within the body. A surgical broach may be rigidly attached to the broach end of the elongated body. An automated surgical impactor may be attached to the impactor end.

A surgical or arthroscopic method for resurfacing at least one surface of a hip joint of a human patient, using a medical device comprising an artificial hip joint surface, wherein the hip joint surface comprising an acetabulum surface and a caput femur surface, said method comprising the steps of: creating at least one hole passing into the hip joint, dissecting and preparing the hip joint, introducing at least one artificial hip joint surface, comprising at least one of an artificial acetabulum surface and an artificial caput femur surface, wherein said at least one artificial hip joint surface, comprising a first sealing member, creating a sealed hollow space between said first sealing member and one of the acetabulum surface or said artificial acetabulum surface and one of the caput femur surface or said artificial caput femur surface, selecting at least one artificial hip joint surface and injecting a material into said hollow space.

A device for forcefully inserting a surgical implant in a recipient bone by impaction, comprising an impactor (10) that exerts an impaction force on the implant and is associated with at least one sensor (12). The sensor (12) measures a value from among the exerted impaction force and the deformation of the impactor (10) and provides a measurement signal representing the temporal variation of said value during an impact. The sensor (12) is connected to a processing unit (30) that is configured to compute, on the basis of the temporal variation of said value during the impact, an indicator representing the level of contact between the implant and the recipient bone. The indicator corresponds to the duration separating the instant corresponding to the first maximum amplitude peak of the measurement signal from the instant corresponding to the second maximum amplitude peak of the measurement signal. The implant can be a femoral rod (2).

Apparatus (20) for performing a joint replacement procedure comprising: a vibrator (50) configured to be coupled to a stem (120) and be excited stem out from the canal.

Systems and methods for ascertaining a position of an orthopedic element in space comprising: capturing a first and second images of an orthopedic element in different reference frames using a radiographic imaging technique, detecting spatial data defining anatomical landmarks on or in the orthopedic element using a deep learning network, applying a mask to the orthopedic element defined by an anatomical landmark, projecting the spatial data from the first image and the second image to define volume data, applying the deep learning network to the volume data to generate a reconstructed three-dimensional model of the orthopedic element; and mapping the three-dimensional model of the orthopedic element to the spatial data to determine the position of the three-dimensional model of the orthopedic element in three-dimensional space.
