Within examples, a surgical device with an embedded sensor system for performing hip replacements is described. This device mitigates fracturing of the mid metaphyseal/diaphyseal region of the femur, and ensures adequate press-fit of the component into the bone. The device relays information regarding forces experienced by the patient's bone to a separate data acquisition device and displays it on an interface. This information is used by the surgeon to determine the force present inside of the patient's bone during broaching, and can then be used to provide better care, and mitigate fractures due to overloading in the bone.

The present disclosure includes apparatuses for a bone graft harvesting device. An example apparatus includes a blade tip including a proximal end and a distal end, wherein the distal end of the blade tip includes a number of blades configured to morcellate bone in response to being rotated and a lead tip located within the blade tip and configured to maintain the bone graft harvesting apparatus centered on a bone graft punch hole.

A tibial alignment device includes an upper part for coupling with a tibial cutting guide and a lower part coupled to the upper part to be vertically slidable, wherein the upper part includes a cutting guide coupling part configured to mount the tibial cutting guide, and a connection part to connect the upper part and the lower part, and the lower part includes an ankle forceps part, wherein the cutting guide coupling part includes a fastening member for coupling to the tibial cutting guide, and a reception member to slidably receive the fastening member, wherein the fastening member includes a coupling part that protrudes to be coupled to the tibial cutting guide, the reception member includes a coupling part that protrudes to be coupled to the tibial cutting guide, and the coupling part of the fastening member is capable of adjusting a gap with respect to the coupling part of the reception member.

A method and apparatus for treating tissue are disclosed, including intra-operative mapping of a probe ablation zone. The method uses a system that maps the proximal and distal margins of the probe ablation zone using tools that access the ablation target. In some embodiments, the tools comprise a bone drill, and an introducer assembly, including a cannula and a stylet. The tools have features or markings that cooperate to indicate which probe to use to achieve the desired ablation. The method further facilitates planning probe placement for delivering energy to treat (ablate) a desired ablation volume of a target tissue by using a system that maps both the target tissue and possible probe ablation zones.

Various embodiments of a surgical instrument are disclosed. The surgical instrument includes a handle, a working element extending from the handle configured to be positioned internal of a target site while the handle is external to the target site, and a laser guide configured to generate at least one emitted marker. The emitted marker corresponds to movement of the working element internal of the target site. Various embodiments of methods using the surgical instrument are also disclosed.

A surgical system and procedure are provided for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration. An auxiliary correction guide can be passed along the k-wires to further rotate and/or translate the first bone relative to the second bone from the corrected configuration to an adjusted configuration.

In a particular implementation, an apparatus configured to measure bone temperature during drilling includes a processor and an infrared (IR) sensor coupled to the processor and configured to measure temperature data indicating a temperature at an interface between a drill bit and a bone of a patient.

A front end attachment for a powered surgical tool comprises a nose and an irrigation fitting. The nose extends forward from a proximal end of the nose. The nose defines a bore and an enclosed channel. The bore is for receiving a cutting accessory for movement therein. The enclosed channel extends longitudinally and helically along the nose such that, as the channel extends longitudinally, the channel curves around the nose so as to curve around the bore. The irrigation fitting is received by the enclosed channel in the nose.

Medical devices are disclosed. For example, a medical device includes an elongated member. The medical device includes a hole forming surface along a portion of the elongated member. The medical device includes an open cell element in physical communication with the elongated member. The open cell element is configured to house at least a first portion of a biocompatible substance.
