The invention relates to a front sight laser aiming auxiliary device which is used for guiding a kirschner wire to present a point-shaped perspective shadow on a C-arm screen in an orthopedic operation, and belongs to the technical field of medical instruments. The device aims at solving the problems that in traditional Kirschner wire perspective point forming operation, repeated perspective depends on the experience of an operator, radiation exposure is large, and operation precision is difficult to guarantee. The device mainly comprises a front sight base which can be fixed on the surface of a receiver of the C-arm machine, wherein a ball head base is arranged in the center of the front sight base; and the ball head laser indicator is arranged on the base and is adjustable in laser direction. When in use, the perspective image is adjusted to the central position of the front sight on the screen by moving the metal point on the operating table. Installing a laser lamp, adjusting the laser lamp to irradiate on a metal point on an operating table, and screwing a nut to fix the position of the laser lamp at the moment. Therefore, a visible laser guide line coinciding with the path of the target X-ray beam is established. And an operator only needs to adjust the guide needle along the laser ray and place the guide needle, so that the guide needle can be stably developed in a point shape in a perspective image, and accurate and rapid screw guide needle placement is realized. The device is simple in structure, low in cost, intuitive in operation, capable of remarkably reducing intraoperative radiation and reducing dependence on experience of operators, and suitable for being used in hospitals of all levels to carry out precise orthopedic surgery under perspective guidance.

The present disclosure provides a surgical method for treating Haglund's deformity and posterior insertional calcific Achilles pathology. The method comprises positioning a patient prone under general anesthesia, using fluoroscopic guidance to identify and mark anatomical landmarks on a calcaneus, and creating two proximal surgical incisions. The method includes separating medial and lateral edges of an Achilles tendon from overlying paratenon using a paratenon fascial elevator to preserve paratenon vascularity. The method comprises placing loop locking sutures along medial and lateral tendon edges using an Achilles suture passer device and creating a mini-open lateral incision for direct access to the Haglund's deformity. The method includes resecting a bony deformity and debriding calcific deposits under direct visualization, securing the Achilles tendon using knotless suture anchors with a rip-stop loop locking technique, and creating subcutaneous tunnels for crossed suture tape placement that provides compression fixation.

Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip.

The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.

This invention relates to the field of fungal infection detection technology and discloses a fluorescent detection device for fungal infections in dermatology and cosmetology. The device includes a fluorescent microscopy mechanism, with a loading rotation control mechanism and a detection auxiliary cleaning mechanism connected to its outer end. The fluorescent microscopy mechanism includes a fluorescent microscopy base. The loading rotation control mechanism includes a rotating disk, with a drive gear ring fixedly connected to the outer wall of the rotating disk. A connecting frame is fixedly connected to one side of the fluorescent microscopy base. This invention, through the combined use of the detection auxiliary cleaning mechanism and the spray auxiliary cleaning mechanism, atomizes and wets the sample surface and performs rolling scrubbing before sample detection, effectively removing stubborn stains such as dust and fingerprints from the sample surface. This avoids interference from these impurities with the fluorescent signal, thus significantly improving the accuracy of fluorescence detection. Furthermore, by achieving both rotating loading and cleaning effects through a single drive, it realizes automated sample loading and cleaning, reducing energy consumption.

This application discloses systems and methods for pose estimation and calibration of fluoroscopic imaging systems in image-guided surgery. A method performed by a computing system includes receiving first fluorescein image data of a first reference marker in a surgical coordinate space from a fluorescein imager having a first set of parameters. The method includes receiving a configuration of the first reference marker in the surgical coordinate space. The method includes determining a second set of parameters of the fluorescein imager in the surgical coordinate space based on the first fluorescein image data and the configuration of the first reference marker. In some embodiments, determining the second set of parameters includes developing a calibration model of the reference marker in the surgical coordinate space from the first fluorescein image data and the configuration of the first reference marker.

Instrument that allows the retrieval of metallic foreign bodies lost in the disc space (Figure 1). This instrument has two jaws (Figure 2) which open like those of scissors but whose particularity is that one of the jaws is magnetized so that the metallic foreign body adheres to it (Figure 3), the second jaw then catches it by means of a conical clamping (Figure 4), which allows a capture on the spot of the foreign body while preventing it from escaping deep into the disc space. We propose a second configuration of the surgical instrument (Figure 6), which increases the functional clearance between the two jaws to allow for the retrieval of foreign bodies of varying thicknesses. This solution is equipped with three springs of different stiffnesses, positioned coaxially with the jaws' axis of rotation, with transverse displacement to accommodate different thicknesses of foreign body to be retrieved. The central spring maintains a minimal initial play, which gradually increases as the jaws close. Conversely, the two outer springs apply a clamping force that ensures the captured foreign object is immobilized. This instrument is very easy to use. With the jaws open, the instrument is inserted into the disc space parallel to the vertebral endplates. The foreign object will be attracted to the magnetic jaw. Once in place, and under fluoroscopic guidance, the surgeon closes the jaws of the forceps, allowing for safe retrieval of the foreign body. We propose that this instrument be included in the standard equipment of all spinal surgery operating rooms. Indeed, although rare, the loss of a metallic foreign body at the surgical site, particularly within the disc space (e.g., a broken instrument or scalpel blade), is potentially serious. The invented instrument represents a "life-saving tool" that helps to avoid further complications, including life-threatening situations.
