A high-frequency sphincterotomy knife with dilation function

This invention discloses a high-frequency sphincterotomy knife with expansion function. By incorporating a deployable expansion component at the front end of a traditional high-frequency sphincterotomy knife, the device can appropriately expand narrow channels before tissue incision, effectively increasing the endoscopic field of view and providing a larger operating space. This allows doctors to more clearly observe diseased tissue and surrounding structures, thereby improving the accuracy of the incision operation. Simultaneously, the expansion claw, driven by a slider, can achieve controllable extension and retraction, allowing the expansion range to be adjusted according to actual surgical needs. The positioning guide post ensures the stability of the expansion claw during movement, preventing displacement or interference of the expansion structure. Furthermore, the ball-head structure at the front end of the expansion claw reduces the risk of damage to the inner wall of the channel during expansion, thus improving the safety and reliability of the surgical operation and demonstrating good clinical application value.

Surgical instrument for retrieving metallic objects lost at the surgical site

UndeterminedTN2024000332A1Spinal columnSurgical site
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.
