  • the first resisting member 710 may include an iron block.
  • the first conflicting member 710 is driven and dragged upward in FIG. 18 until the first slider 931 moves to a certain position, and the second slider 931 The block 932 locks the position of the first slider 931 . It can be understood that those skilled in the art can also configure the first conflicting member 710 and the second conflicting member 720 in other force transmission methods such as buckle or thread, which will not be further described in this embodiment.
  • the first interference component 710 on the surgical instrument 221 will change its position and/or posture due to mechanical movement, so that the operator can The surgical instrument 221 whose service life reaches the limit is identified through the appearance to improve the identification rate and save unnecessary instrument installation time.
  • the surgical instrument protection device includes: a mandatory protection unit and a counting unit; the mandatory protection unit has a first state and a second state, and when the compulsory protection unit is in the first state, it allows The surgical instrument is installed on the installation part; when the mandatory protection unit is in the second state, the surgical instrument is prohibited from being installed on the installation part again; the counting unit is used to obtain the service life of the surgical instrument, and When the service life of the surgical instrument reaches a limit value, a driving signal is sent to an external power unit; furthermore, the forced protection unit is switched from the first state to the second state driven by the power unit.
  • the compulsory protection unit switches from the first state to the second state, thereby prohibiting the surgical instrument from being installed on the mounting part again, thereby playing a role of compulsory protection, so that the limited Surgical instruments with a service life cannot be installed in the installation part again, eliminating the risk of reuse.
  • the mandatory protection unit since the mandatory protection unit is switched from the first state to the second state, it can be recognized by the appearance that the surgical instrument cannot be used again, and the operator's recognition rate of the surgical instrument that has reached the limit of its service life is improved.

Abstract

La présente demande concerne un appareil de protection d'instrument chirurgical, un instrument chirurgical, une partie de montage, ainsi qu'un ensemble instrument chirurgical. L'appareil de protection d'instrument chirurgical selon l'invention comprend : une unité de protection forcée et une unité de comptage ; l'unité de protection forcée présente un premier état et un deuxième état : lorsque l'unité de protection forcée se trouve dans le premier état, l'instrument chirurgical peut être monté sur la partie de montage, et lorsque l'unité de protection forcée se trouve dans le deuxième état, l'instrument chirurgical ne peut pas être remonté sur la partie de montage ; l'unité de comptage est utilisée pour obtenir la durée de vie de l'instrument chirurgical et envoyer un signal d'entraînement à une unité d'alimentation externe lorsque la durée de vie de l'instrument chirurgical atteint une valeur limite ; puis l'unité de protection forcée est commutée du premier au deuxième état sous l'entraînement de l'unité d'alimentation. Ainsi, lorsque la durée de vie de l'instrument chirurgical atteint la valeur limite, l'unité de protection forcée passe du premier au deuxième état, empêchant ainsi le remontage de l'instrument chirurgical à des fins d'utilisation.
