During minimally invasive surgeries, such as laparoscopic surgery, trocars are used to permit access into a patient's body. Trocars are medical devices or instruments that comprise hollow tubes or hollow portions. During surgery, such as laparoscopic surgery, a trocar may be inserted through an incision into a patient's body, such as into the abdominal or pelvic cavity of a patient. The trocar acts as a passageway for other surgical tools or devices, such as scopes, laparoscopes, microscopes, knives, graspers, scissors, staplers, and more, to enter the body for use during surgery.

During such surgical procedures, the lenses of viewing devices inserted into the body through the trocar, such as scopes, laparoscopes, and/or microscopes, may become clouded or the view therethrough may become partially or completely obscured. The view can be obscured, either partially or completely, if the lenses are smeared with bodily fluids or the like, or if the lenses become clouded or fogged over due to the humidity within the body of the patient. In addition, the interior of the trocars should also be kept clean.

An object of the present application may be to provide a cleaning device for a trocar and surgical scopes, which cleaning device may be utilized during surgery. The cleaning device also may be used to defog lenses or optics of a surgical scope.

DESCRIPTION OF THE INVENTION

FIG. 1 shows a trocar 10 used in minimally invasive surgery. The trocar 10 has a cleaning device 12 removably connected thereto. The cleaning device 12 as shown is snapped onto the trocar 10 using a snap member 14. However, this is not to be construed as limiting the present disclosure as any suitable attachment element, such as a hook-and-loop fabric, buckles, clips, tape, etc., configured to securely and removably attach the cleaning device 12 to the trocar 10 may be utilized.

An embodiment of cleaning device 12 is depicted in FIG. 1 in an exploded view. The cleaning device 12 comprises a casing 15 having the snap member 14 attached to an outside rear surface thereof. A first depression 24 may be formed in an upper surface of the casing 15 of cleaning device 12 to receive a sponge 20. In one example, the sponge 20 may be impregnated with a cleaning medium 22. The casing 15 may further include a second depression 26 formed in an upper surface thereof and disposed opposite the first depression 24. The second depression 26 may be configured to receive a heating element therein. In one example, the heating element can comprise batteries 16 and a heating coil 18 operatively connected to the batteries 16. The heating coil 18 may be configured to warm a microscope, laparoscope, or other surgical scope (not shown) so that the scope is ready for reinsertion in the trocar 10 and ready for reinsertion into the body of the patient being operated upon. Instead of batteries 16 and heating coil 18, a chemical pack housing chemicals that combine in an exothermic reaction, such as is used by skiers in their gloves to keep their hands warm while skiing, may be used as the heating element.

In one exemplary use of the cleaning device 12, the scope being utilized in a surgical procedure is removed from the trocar 10. It is first wiped off on the sponge 20, thereby to remove matter from the patient which has built up during the surgical procedure or which has condensed upon the scope during the surgical procedure. The heating element is then used to heat the front of the scope, thereby heating the front of the scope above the temperature of the patient to discourage the formation of condensate on the front of the scope when the scope is within the body of the patient. One or more lights 36, such as light emitting diode (LED), may be positioned on casing 15 and used to provide illumination for the trocar 10 and the site where the trocar 10 is inserted into a patient. The lights may be operatively connected to batteries 16.

FIG. 2 shows a top view of cleaning device 12 attached to trocar 10. The second depression 26 may further include a heating chamber cover 28 positioned over the top thereof to provide protection for the heating element. The heating chamber cover 28 may further include a microfiber holder 30 formed therein configured to hold a microfiber cover 31. The heating chamber cover 28 and the microfiber cover 31 may be configured with at least one scope access hole 32 which permit the microscope or other scope to be inserted into heating chamber 33 to be warmed by heating coil 18, a heating pack, or some other manner known in the art. Microfiber cover 31 may be used by surgical staff to wipe debris and/or fluids from a scope in order to clean the optics thereof prior to inserting the scope into the scope access hole 32 to be heated. In an embodiment, microfiber cover 31 may be disposed on heating chamber cover 28 within the holder 30 in order to provide easy access to surgical staff.

With further reference to FIG. 2, in one example, casing 15 may have a substantially isosceles triangular shape when viewed from above, with the two sides of the triangle that are not of equal length not adjacent to the trocar 10. Such a configuration may have the benefit of optimizing placement of the heating coil 18 and batteries 16 in casing 15 next to sponge 20. This configuration also may have the benefit of providing easy access to cleaning device 12 while minimizing interference of the device with access to the surgical site while the cleaning device 12 is attached to the trocar 10 during a surgical procedure.

In FIG. 3, the trocar 10 is shown again with the cleaning device 12 attached thereto by snap member 14. An advantage of such an embodiment is that it places cleaning device 12 in close proximity to trocar 10, and thereby provides easy access to surgical staff. Such an embodiment also has the advantage that cleaning device 12 does not need to be set on a separate tray.

With reference to FIGS. 3 and 4, sponge 20 is shown in its installed position in first depression 24 in casing 15. Sponge 20 may be comprised of any material known in the art. Sponge 20 may be used for cleaning debris and/or fluid from a scope. Sponge 20 also may be impregnated with cleaning medium 22, such as a cleaning and/or defogging fluid. In an embodiment, cleaning medium 22 and or sponge 20 may be sterile.

FIG. 4 shows the trocar 10 with an embodiment of cleaning device 12 from a different angle than the previous figures. Holes in microfiber cover 31 and heating chamber cover 28 create the scope access hole 32, which allows a scope to access heating chamber 33 in second depression 26, where heating coil 18 may warm and aid in defogging a scope. Debris may be wiped from a scope's optical components by surgical staff on microfiber cover 31 and/or sponge 20, which may be impregnated with cleaning medium 22.

FIG. 5 is another exploded view of the cleaning device 12 having the casing 15. The casing 15 comprises an attaching mechanism, such as snap member 14, which is configured to attach to a trocar. Snap member 14 is configured to removably attach to trocar 10. Other embodiments of casing 15 may be configured to attach to trocar 10 with tape, a friction fit, or through another mechanism otherwise known in the art.

The casing 15 also comprises a first depression 24, which is configured to hold a sponge 20. The sponge 20 may be at least partially moistened with cleaning medium 22. The casing 15 also comprises second depression 26 which is configured to hold batteries 16 and heating coil 18 or a defogger, and forms heating chamber 33. Second depression 26 may hold one or more batteries 16, which in an embodiment includes three lithium batteries. In other embodiments, other types of batteries 16 may be used or adapted for use, and other numbers of batteries may be used. In another embodiment, another heating source other than an electrical or battery-powered heating source could be utilized, such as a chemical heat source or chemical heat pack, which would avoid the use and ultimate disposal of batteries, which can present challenges due to the potential environmental impact of battery waste.

The second depression 26 and heating chamber 33 of the casing 15 may be at least partially covered by heating chamber cover 28. The heating chamber cover 28 may comprise the microfiber holder 30 and scope access hole 32. A scope or microscope may be inserted into the scope access hole 32 and through the heating coil 18 or defogger. The scope or microscope may be wiped on the microfiber cover 31 disposed in the holder 30 before or after insertion into the scope access hole 32.

In at least one possible embodiment, a structure or material, such as double-sided adhesive tape, could be connected or attached to the casing 15, such as the side or underside, to allow the casing 15 to be connected or attached to a support structure.

FIG. 6 shows a partially transparent view of an embodiment of a cleaning kit 124 attached to a trocar 106. The kit 124 includes a container 105 that may house a sponge 110, which may be impregnated with a cleaning solution, and a heater 109. A cover 101 is located on top of the container 105. The cover 101 has an opening therein into which can be inserted a surgical viewing device 100, such as a scope, laparoscope, or microscope, such that the scope lens 111 is inside the container 105. In an embodiment, cover 101 may include one or more recesses 120, at least one of which contains a microfiber wipe or cleaner 102. Also shown is a cannula cleaner 114, which is held by two cannula cleaner tube holders 103. Holders 103 may removably secure the cannula cleaner 114 to the container 105 when it is not in use during a surgical procedure. Cannula cleaner 114 may be secured by a friction fit, or in some other manner otherwise known in the art. In addition, the cover 101 may have one or more projections 126 that project out above the cannula cleaner 114 to further secure the cannula cleaner 114 in place in a secured position on container 105.

An embodiment of cannula cleaner 114 may include an elongated body with a cleaning tip 104 disposed at one end. In an embodiment, the body of the cannula cleaner 114 may comprise a tube that also functions as a solution container 107. On the end opposite the cleaning tip 104 is located a solution dispensing valve 108. Either the valve 108 or the solution container 107 may be squeezed or pinched or pressed in to cause an amount of a cleaning or defogging solution, or some other liquid known in the art, to be dispensed. The solution may be dispensed into the container 105. By containing the solution in the cannula cleaner 114, a supply of cleaning solution is readily available to be dispensed into the container 105, and is in easy reach for a user of the trocar 106 and cleaning kit 124, such as by a surgeon or other medical professional. By mounting the cannula cleaner 114 on the container 105, the cannula cleaner 114 is easy to reach for use in cleaning or clearing out the trocar 106. The design of the cannula cleaner 114 therefore combines a cleaning device with a cleaning solution supply, so as to facilitate keeping the trocar 106 and viewing instruments clean during a surgical procedure. However, it should be understood that other embodiments of cannula cleaner 114 may exist, such as an embodiment that does not hold solution and lacks a solution dispensing valve 108. Another embodiment may include cleaning tips 104 at both ends of the cleaning device 114. In such an embodiment, the cleaning tips 104 may be of the same size or of different sizes. Cannula cleaning tip 104 may be comprised of a sponge, foam, microfiber, or some material otherwise known in the art.

FIG. 7 shows another view of the cleaning kit 124 shown in FIG. 6. In FIG. 7, container 105 is shown as transparent in order to demonstrate how scope 100 may be inserted through scope access hole 116, so that the optics thereof may contact sponge 110. However, it should be understood that not all embodiments of container 105 need be transparent. FIG. 7 also depicts how scope 100 may interact with an embodiment of heater 109. In an embodiment, heater 109 may be configured to surround or partially surround scope 100, and may substantially border the perimeter or part of the perimeter of sponge 110. Heater 109 and sponge 110 may be configured to create a substantially cylindrical space, where the lens 111 of a scope 100 may be inserted for cleaning and/or defogging, which may be preferable to engage embodiments of scopes 100 that are substantially cylindrically-shaped. In an embodiment, sponge 110 may be configured to maximize efficient contact with lens 111 of scope 100. In an embodiment, sponge 110 may be substantially circular in shape. Embodiments of heater 109 may comprise other shapes. Embodiments of heater 109 may use electrical or chemical processes to generate heat, or may do so using another manner known in the art.

With further reference to FIG. 7, cannula cleaner 114 may be inserted into a cannula 128 of trocar 106 to clean the cannula 128 of fluids, condensates, and/or debris. In an embodiment, cannula cleaning tip 104 may be inserted into cannula 128. In an embodiment, cannula cleaning tip 104 may have a diameter that is substantially the same or larger than the diameter of the cannula 128. Cannula cleaning tip 104 may be comprised of a deformable material, and deform to fit into cannula 128 while contacting the walls of the cannula 128. Cannula cleaning tip 104 may be sufficiently absorptive to absorb fluids and/or condensate present in trocar 106. Trocar 106 is shown as transparent in order to better illustrate the insertion of cannula cleaner 114 therein; however, it should be understood that embodiments of trocar 106 need not be transparent.

FIG. 8 shows a perspective view of the cleaning kit 124 depicted in FIG. 6. Cannula cleaner 114 is shown disposed on cannula holders 103, which are configured to contain cannula cleaning device 114 against container 105 during a surgical procedure when cannula cleaner 114 is not in use. In an embodiment, cover 101 of cleaning kit 124 may include projection 126 that is configured to further constrain cannula cleaner 114 when not in use. Cover 101 may include one or more microfiber wipes 102 disposed thereon to further aid in cleaning debris or condensate from a scope 100. While the embodiment shown in FIG. 8 shows a configuration wherein two microfiber wipes 102 are positioned on cover 101 roughly on either side of scope access hole 116, it should be understood that other configurations or numbers of wipes 102 may be used. It also should be understood that embodiments of cover 101 need not include microfiber wipes 102, and that other materials or wiping elements otherwise known in the art may be used to wipe debris from the lens 111 of a scope 100. Wipes 102 may be disposed in one or more recesses 120 in cover 101. Cleaning kit 124 may removably attach to trocar 106 by a snap member 118, or another manner known in the art.

FIG. 9 shows a perspective view of a portion of the container 105 of the cleaning kit 124 shown in FIG. 6. An embodiment of container 105 may be integrally molded with snap member 118 and/or one or more cannula cleaning device holder 103. The interior of container 105 may comprise a single chamber, or multiple chambers. The at least one chamber may include one or more support posts 122. Support posts 122 may provide support for cover 101, and may provide support for configurations of heater 109. In embodiments of heater 109, posts 122 may support configurations of batteries, a heating coil, chemical packs, or other components of a heater 109 otherwise known in the art.

FIG. 10 shows another view of the cleaning kit 124. In an embodiment, cannula cleaner 114 may be used to dispense cleaning and/or defogging solution into container 105 through scope access hole 116. In an embodiment, solution may exit solution container 107 of cannula cleaner 114 through solution dispensing valve 108. When solution—represented by a droplet of cleaning solution 130—enters through scope access hole 116, it may contact and be absorbed by sponge 110. A scope may then be inserted into container 105 through scope access hole 116 and contact impregnated sponge 110, which may aid in cleaning and/or defogging the scope 100.

With reference to FIGS. 11 and 12, an alternative embodiment of a cleaning kit 224 is illustrated. Cleaning kit 224 is configured to clean lens 211 of a scope 200 and may include a container 205 that is shorter or thinner than the embodiment of the container 105 shown in FIG. 6. In the example in FIG. 11, no batteries are utilized, so a shorter or thinner container 205 can be utilized. In an embodiment, the kit may use no heating device or heating medium. In another embodiment, a chemical heating medium or chemical heating pack may be used which takes up less space than batteries. Cover 201 also may include a microfiber wipe or cleaner 202 that spans most or all of the surface area of cover 201. FIG. 11 depicts two cannula cleaners 214 in order to demonstrate both insertion into trocar 206, and placement in cleaner tube holders 203.
