A surgical tool includes (i) a tool body with a longitudinal bougie passage extending through the tool body to receive a bougie therethrough and (ii) a blade body mounting a scalpel on one end thereof. When the bougie is removed, the blade body can be inserted through the bougie passage so that the scalpel blade protrudes from the end of the tool body in a working position. The surgical tool is suited for performing a cricothyrotomy procedure by incising the cricothyroid membrane in the working position of the scalpel blade, followed by retraction of the scalpel blade to allow insertion of the bougie through the bougie passage while the tool body remains in place within the incision. The tool body can then be removed from the bougie and replaced with an endotracheal tube, prior to removal of the bougie from the incision.

Provided is an ultrasonic surgical knife blade. The projection of the blade on a shear plane is banana-like curved shape. From a proximal end to a distal end, the thickness of the blade varies from thick to thin, and then to thick and to thin again. The projection on a vertical shear plane is fruit knife-shaped. The height of the blade varies from high to low, and then gradually decreases, and an arc-shaped cutting groove is formed in the middle position. The present invention allows for an increase of swing amplitude in the bending direction and the effective working length of the blade. A boat-shaped or arc-shaped balance cutting groove is provided between the most distant node and a tip of the blade, such that the stability of ultrasonic vibration is improved.

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.
