A surgical instrument assembly may include a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The processor can be configured to determine a position of the medical imaging device, from which the medical imaging device can generate an X-ray image that includes holes of an intramedullary nail shown as circles, for instance perfect circles. In an example, the processor identifies the intramedullary nail, so as to determine an intramedullary nail identity, and determines the position of the medical imaging device based on a portion of at least two locking holes of the intramedullary nail and based on the intramedullary nail identity.

A surgical instrument for transmitting torque is described. The surgical instrument comprises a torque receiving portion at a proximal end of the surgical instrument, a torque delivering portion at a distal end of the surgical instrument, and a flexible shaft extending between the torque receiving portion and the torque delivering portion. The flexible shaft comprises torque transmitting elements coupled in series along a longitudinal direction of the shaft such that one of the torque transmitting elements is rotationally fixed and tiltable relative to an adjacent one of the torque transmitting elements, wherein each of the torque transmitting elements comprises a through-hole. The surgical instrument also comprises an elongate alignment member extending through the through-holes of the torque transmitting elements, wherein the alignment member is made from a spring-elastic material. The present disclosure further provides a system comprising the surgical instrument and a method of using the surgical instrument.

A system for targeting a feature on a surgical device, includes a shape sensing element coupled to an interrogator and operable to provide information to related to said portion's position in a reference frame in communication with the targeted feature. The interrogator is operable to poll the shape sensing element for information related to said portion's position in the reference frame. A surgical tool is coupled to the targeting system in communication with the shape sensing element. The data processor is operable to communicate with the interrogator to output position information of the portion of the shape sensing element with respect to a calibrated position, defined as the position of the portion of the shape sensing element in the reference frame when the guide axis is aligned to the targeted feature. A display provides the user visual information comparing the position of the tool to the targeted feature.

A computer program element and a device are provided for processing a 2D projection image generated during a procedure of fracture treatment of a bone. The computer program element comprises sets of instructions for detecting the reference body in the 2D projection image, detecting at least one element out of the group consisting of an instrument, an implant and an anatomical structure in the 2D projection image, and identifying a current state of the element, determining a state of progress of the procedure of fracture treatment, and providing information regarding steps to be performed next.

An IM tibial nail aiming guide for providing proximal and distal screw fixation in an intramedullary nailing (IMN) of a tibia includes an attachment that connects and disconnects easily from a jig's proximal handle. Specifically, the IM tibial nail aiming guide functions as an aiming guide for accurate fixation of all the respective proximal and distal screw holes in a tibial nail. The IM tibial nail aiming guide has a length and angle that are adjustable, affording the ability to use this IM tibial nail aiming guide with any tibial nail. This IM tibial nail aiming guide is made of radiolucent material that allows for a confirmatory fluoroscopic imaging to verify that both the proximal and distal screws are fixated appropriately. The IM tibial nail aiming guide permits a more accurate, safe, versatile, and efficient approach to tibial IMN.

Apparatus and methods for preparing the interior of a bone for therapy. The therapy may include therapy for a bone fracture. The apparatus and methods may involve orienting a surgical instrument for proper deployment in the interior of the bone. An instrument guide may be positioned and retained against translation along, and rotation about one or more of three substantially orthogonal axes. Apparatus placed exterior to the bone may register the guide to a region inside the bone that is designated for preparation or treatment. One or more broaching members may be used to prepare the region for treatment. A broaching member may be expandable inside the bone. A broaching member may be flexible such that it broaches bone having a relatively lower density and it leaves bone having a relatively higher density substantially intact.

An assembling kit for installing intramedullary nail is provided, which is suitable for assisting in fixing a securing member to at least one fixing hole of an intramedullary nail placed in a bone. The assembling kit for installing intramedullary nail includes a drilling member, a guiding member and a hole-reaming member. The drilling member is configured to form an opening on a surface of the bone and has a tapping portion. A diameter of the tapping portion is greater than a diameter of the fixing hole. The guiding member is configured to be put into the fixing hole along a central axis. The hole-reaming member is sleeved on the guiding member and is configured to ream the opening to form a mounting hole. The hole-reaming member has a reaming portion, and a diameter of the reaming portion is greater than the diameter of the tapping portion.

Described herein are methods and devices useful for reaming and shaping the surfaces of a joint in a mammalian body. The reaming and shaping devices and methods are particularly useful in preparation of a joint for a minimally invasive joint replacement or resurfacing, though they may be used as part of any appropriate arthroplasty procedure.

Alignment guide systems, fixation guide devices, and methods for positioning and inserting an intramedullary nail are disclosed. The alignment guide system includes a targeting guide with a first end and a second end, an alignment wire rotatably engaging a second end of the targeting guide, and a guide sleeve insert engaging an opening in the first end of the targeting guide. The fixation guide device including a frame including a first end and a second end, a compression device slidingly coupled to the first end of the frame, and the intramedullary nail secured to a nail attachment apparatus of the frame. A method of inserting an intramedullary nail into two bones for fixation of the two bones is also disclosed.

A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The display can be configured to display visual information comprising X-ray images generated by a medical imaging device, depth gauge information generated by a depth gauge coupled to the surgical instrument, and trajectory information associated with various intramedullary nailing operations.
