Definitions

  • the invention relates to medical technology, namely to a cordless electric surgical instrument with a collapsible structure, intended for use in surgery, in particular for the treatment of bone tissue and a method for sterilizing it.
  • tool refers to any device consisting of an electric motor, a mechanical transmission, a battery and an external case, regardless of its functional purpose.
  • a common and well known requirement for a surgical instrument is sterility.
  • Sterility of a surgical instrument is achieved in two ways:
  • Sterilization of a surgical instrument is the process of destroying all types of microbial flora, including their spore forms, fungi and viruses.
  • the most common sterilization methods are autoclaving and a dry oven.
  • the autoclaving protocol prescribes the processing of surgical instruments at a temperature of 134 ° C, a pressure of 0.2 MPa and 100% humidity [1].
  • a cordless surgical power tool consists of an electric motor, control board, battery, and transmission.
  • Another solution is implemented in the invention [6] and is an electromechanical hand tool with a double body, the inner one is non-sterilizable and contains all functional elements and the outer one is used as a case for the first one, which does not have functional parts and is subject to sterilization before each use.
  • This invention solves the problem of protecting the instrument components from harmful sterilization conditions, but does not avoid the disadvantages inherent in disposable casings [3]; [4]; [5], namely, the high cost of manufacturing a double body and low ergonomic properties.
  • SUBSTITUTE SHEET (RULE 26)
  • the aim of the present invention is to provide a reusable surgical electrical instrument of modular design, allowing its selective sterilization, namely, removal of the electric motor and its transmission, power supply circuit and electronic control, followed by sterilization of the empty case to prevent exposure to aggressive conditions on the components and parts of the device.
  • the essence of the invention and the method of its implementation are disclosed by the description of images (Fig. 1-6)
  • An electric surgical instrument of a collapsible design consists of a one-piece hollow metal case, inside which structural elements are located: a button for controlling the speed and direction of rotation 8 of an electric motor 2, a cannulating tube 9, a cover 14 and removable components: a power module block 15, a battery 5 with an adapter 4.
  • the power module block 15 contains an electric motor 2 with a gearbox 3, an electronic motor control unit 17 and a contact group 12-13.
  • the spindle 6 is connected to the body 1 with the chuck 7.
  • the spindle 6 and the cartridge 7 have a longitudinal channel coaxial with the cannulation tube 9, which ensures the through passage of the orthopedic conductors.
  • the battery compartment is closed with a cover 14.
  • Control of the speed and direction of rotation of the electric motor is provided by the button 8.
  • the current position and movement of the button (rod 8.2) is read by the optical sensor 16 and, through contacts 13, is transmitted to the motor control unit 17.
  • the lid 14 is equipped with a magnetic locking system, without external buttons or levers.
  • the block of the power module 15, containing the electric motor 2 with the gearbox 3 and the control unit 17, is loaded into the cavity of the housing 1 by means of a sterile guide funnel, which excludes possible contact of non-sterile components with the outer surface of the housing.
  • the design of the adapter 4 includes a battery charge level analyzer 5 with light and sound indication. At the moment of connecting the adapter, the battery voltage is measured and displayed by indicator 20, consisting of 4 LEDs of different colors with the following values:
  • the tool is disassembled in the reverse order: the battery compartment 14 is opened, the battery is removed, the spindle b and the power module 15 are removed.
  • the bottom of the handle is pressed against the recess in the tool charger.
  • an electromagnet is turned on, the field of which rotates the locking plate 21 by an angle sufficient to disengage the pins 22 from engagement with the housing elements.
  • the housing 1 with the cannulating tube 9 and the button 8, together with the spindle 6 and the cartridge 7 are placed in the sterilization chamber.
  • the wireless (rechargeable) power supply circuit allows maximum mobility during the operation, eliminates the inconvenience and risks associated with the use of a power supply cable and the need to sterilize it.
  • the modular design of the tool allows you to replace any faulty unit - an electric motor, an electronic control unit, a battery - without repairing the entire device and even just before the operation.
  • the electric motor and gearbox are arranged in a separate module, which is structurally a metal sleeve with coaxially located components. This increases assembly accuracy, reduces shaft runout and reduces wear on parts.
  • the brushless electric motor provides more power and efficiency, thus, allowing the most efficient use of the capabilities and resource of the battery, reduces the weight and size of the tool.
  • the one-piece body of the device has smooth contours without gaps and narrows and only 3 connections with additional elements - the engine control button, the battery compartment cover and the screw connection of the instrument holder, which prevents the accumulation of foreign masses during the operation, facilitates cleaning and sterilization of the case.
  • the battery is connected to the adapter before the assembly is inserted into the sterile case, and the presence of a light and sound indicator allows you to assess the condition of the battery and, in case of insufficient charge level, promptly replace it before the operation begins.

Abstract

L'invention concerne un instrument chirurgical électrique à structure démontable que l'on utilise en chirurgie, ainsi qu'un procédé de stérilisation de celui-ci. Cet instrument comprend un corps métallique, un moteur, des cartes de commande et une source de courant, et comprend également un bouton unique de commande de la vitesse et du sens de rotation du moteur. Cet instrument chirurgical se caractérise par une stérilisation sélective, notamment par le retrait du moteur électrique et de sa transmission, des circuits d'alimentation électrique et de la commande électrique, suivi d'une stérilisation du corps vide afin d'empêcher l'action de conditions agressives sur les unités et les parties du dispositif. Cette structure exclut tout contact physique du bouton de commande de vitesse et de direction du moteur avec des éléments électroniques ou électriques de la carte de commande.
