It is noted that references in the specification to “an embodiment”, “some embodiments”, “other embodiments”, etc., indicate that the embodiment described may include one or more particular features, structures, and/or characteristics. However, such recitations do not necessarily mean that all embodiments include the particular features, structures, and/or characteristics. Additionally, when particular features, structures, and/or characteristics are described in connection with one embodiment, it should be understood that such features, structures, and/or characteristics may also be used connection with other embodiments whether or not explicitly described unless clearly stated to the contrary.
The following detailed description should be read with reference to the drawings in which similar elements in different drawings are numbered the same. The drawings, which are not necessarily to scale, depict illustrative embodiments and are not intended to limit the scope of the invention.
An example endoscope and/or endoscope assembly 10 is illustrated in
Endoscopes like the endoscope 10 are useful medical devices for a number of different medical interventions. Due at least in part to the complex nature and expense associated with endoscopes, standard clinical practices include the cleaning/reprocessing of the endoscope so that the endoscope can be properly prepared for re-use. One part of a typical cleaning process may include the removal of debris from one or more channels formed in the endoscope. Disclosed herein are apparatuses/devices generally designed for use in cleaning/reprocessing endoscopes and the like.
The control unit 26 may take on a variety of different forms. For example, the control unit 26 may generally include a housing configured to be coupled to the shaft 28. For example, the control unit 26 may include an internal chamber or socket designed to accept and end region of the shaft 28. In some instances, the shaft 28 can be releasably secured to the control unit 26. In some of these and in other instances, the shaft 28 may be coupled to the control unit 26 in a manner that permits using the control unit 26 to move the shaft 28. In some instances, the shaft 28 is coupled to an end region of the control unit 26. In such instances, the shaft 28 may not extend into an internal region of the control unit 26. In other instances, the shaft 28 may extend partially into the control unit 26. In still other instances, the shaft 28 may extend through the control unit 26 (e.g., so that one portion of the shaft 28 extends from one side of the control unit 26 and another portion of the shaft 28 extend from another side of the control unit 26).
The control unit 26 may include a mechanism for moving the shaft 28. In general, the mechanism for moving the shaft 28 may result in axial and/or translation movement, multi-axial movement, circular movement, rotational movement, orbital movement, vibrational movement (e.g., vibration), reciprocating movement (e.g., reciprocation), oscillating movement (e.g., oscillation), and/or the like. In some instances, the mechanism may be a relatively simple wind-up mechanism that, when activated, can vibrate and/or rotate the shaft 28. For example, the control unit 26 may include a potential energy storage device (e.g., a gear train, spring, combinations thereof, etc.). Once the potential energy storage device is put into a state of high potential energy, the potential energy is converted into kinetic energy by releasing the potential energy, and that is translated to the cleaning assembly 24 (e.g., the shaft 28 and/or the cleaning member 30) through vibrations, oscillations, and/or other periodic motions. For example, the potential energy device may include a winding mechanism, a spring, and one more gears coupled to spring. Winding the winding mechanism winds the spring into a more tightly wound configuration. Releasing the winding mechanism may result in the spring “releasing” or unwinding, thereby causing the gears and, ultimately, the shaft 28 to vibrate, rotate, or otherwise move.
In some instances, other mechanisms for moving the shaft 28 are contemplated. For example, mechanisms are contemplated that utilize planetary gear boxes to drive motion of the shaft. Other mechanisms are contemplated that utilize a push-pull helix drill drive, a hand drive similar to that used in an egg beater. These are just examples. Other mechanisms are contemplated.
Engaging the shaft 28 with the mechanism for moving the shaft 28 may include any one of variety of connections and/or connectors. For example, a bayonet connector may be used, a screw/threaded connector may be used, a magnetic coupling may be used. These are just examples. Other connections are contemplated.
In some instances, the control unit 26 may include a motor (e.g., an electric motor). The motor may be coupled to the shaft 28 so as to move, rotate, translate, vibrate, reciprocate, oscillate, etc. the shaft 28 (and, for example, the cleaning member 30). Thus, the motor may be considered to be a rotary motor, vibrating motor, oscillating motor, etc. In some instances, the motor and/or the control unit 26 may utilize and/or otherwise include a power source. In some instances, the control unit 26 may utilize a direct current power source (e.g., battery powered) and/or a direct current motor (e.g., a battery powered motor). In some of these and in other instances, the control unit 26 may include an alternating current power source (e.g., and/or an alternating current motor) and/or another power source (e.g., solar power; e.g. a solar powered motor). In some instances, the control unit 26 may include a piezo electric source of motion where an electric current is converted into motion (e.g., rotation, translation, vibration, oscillation, etc.) by expansion and contraction of the piezo element. In general, the power source may be used to help provide motion to the shaft 28. In some instances, however, a power source may not be needed in order to provide motion to the shaft 28. In some of these and in other instances, a hand crank mechanism may be used to effect motion. In some of these and in other instances, a hand-operated screw type mechanism may be utilized where a user pushes and/or pulls the mechanism to effect motion.
In at least some instances, the control unit 26 may be designed for multiple uses. For example, the control unit 26 can be releasably attached to the shaft 28 (e.g., a shaft 28 with a cleaning member/brush 30 coupled thereto), used in conjunction with the shaft 28 and cleaning member/brush 30 to clean an endoscope 10, detached from the shaft 28, and then re-attached to another shaft 28 (e.g., another shaft 28 with a cleaning member/brush 30 coupled thereto) so that it can be used to clean another endoscope (e.g., similar to the endoscope 10).
The shaft 28 may include a variety of forms. In some instances, the shaft 28 may be a relatively stiff rod. In other instances, the shaft 28 may be relatively flexible and capable of bending in one or more directions. The cleaning member/brush 30 may be secured to the shaft 28. In some instances, the cleaning member/brush 30 may be replaceable. In other words, the cleaning member/brush 30 may be removed from the shaft 28 and replaced by a new or different cleaning member/brush 30.
In some instances, the shaft 28 with the cleaning member/brush 30 coupled thereto can be used for a number of different cleaning procedures. In other instances, the shaft 28 with the cleaning member/brush 30 may be a single-use item, designed for a single cleaning procedure.
It should be understood that this disclosure is, in many respects, only illustrative. Changes may be made in details, particularly in matters of shape, size, and arrangement of steps without exceeding the scope of the disclosure. This may include, to the extent that it is appropriate, the use of any of the features of one example embodiment being used in other embodiments. The invention's scope is, of course, defined in the language in which the appended claims are expressed.
The present application claims the benefit of and priority to U.S. Provisional Patent Application Ser. No. 63/002,769, filed on Mar. 31, 2020, the disclosure of which is incorporated herein by reference.
