Abstract
Description
[0001]PDSD No.394.0002WO01 Endoscope Speculum, System & Method Field Embodiments herein relate to a speculum for endoscopic examination and medical procedures on a patient’s ear, as well as systems and methos for using the endoscope speculum, including in augmented reality applications. Summary The present disclosure is directed, in part, to improved specula for examination and therapeutic procedures in a patient’s ear. The improved specula can include a variety of features that allow for easier ear examinations, less discomfort for patients, and new and improved therapeutic procedures (such as saline field surgery). The improved features are such that multiple improvements can be made to specula depending upon the intended use. Thus, the subject matter relates to various specula and features of those specula, to those features combined into specific specula designs, methods and systems for using those specula, and also devices for securing the specula to a patient. These features and improvements include: speculum features / functions, ways for affixing or securing specula to a patient, and methods and systems for using the improved specula. The improvements allow for a wide range of specialized specula. Generally, these specula include features that are related to the exterior and interior of the specula, as well as features that are on the proximal (health care provider) region or distal (patient) region of the speculum. Some features are intermediate to the proximal and distal regions of the speculum. Also, it will be appreciated that specula can include a combination of these features. A brief overview of these improved features is provided below. Some of the improvements relate to the exterior of the specula. For example, this can include specula with flexible widths. In one implementation, the speculum has a slit down the side with an overlapping section so that the outer diameter can be varied to snuggly fit within the inner ear. Squeezing the speculum reduces the distal tip size allowing the doctor to use the speculum as a retractor. This design allows the speculum to be more adaptable to different ear sizes. The slit can be designed to PDSD No.394.0002WO01 extend all the way or partially to the proximal end of the speculum, and can also have an overlap or no overlap at the slit. In an example embodiment the distal (patient end) of the tip of the speculum is flexible. This flexibility can be implemented in various regards, including tips that are able to be readily bent, as well as some that are pre-bent. In some embodiments the speculum (and especially the tip) can be made of multiple materials. The speculum can include a living hinge at the distal end that readily adapts to the geometry of the patient’s inner ear. Thus, the tip can be flexible as well as have a certain bend molded into it. Also, the speculum can be made with flexible tips that can be formed using a single material for the whole speculum or using different materials. In some embodiments the tip is made of silicone, which can increase comfort for patients. The tip can optionally clip onto the base of the speculum to allow for different distal tip shapes and diameters. In some embodiments the design has a gasket seal. As noted above, in some embodiments the speculum is made of two components, such as partially of silicone, such as at the tip. A flexible silicone tip increases comfort for patients and decreases chance of injury. This can be especially true for pediatric applications. Such specula can be made, for example, in two shots on an injection mold, thus fusing the plastic and silicone pieces together. Various aspects of improved interiors for the specula are also disclosed. In some embodiments, multiple access lumens and access ports are possible. The speculum can come with a range of lumens for an endoscope. The lumens typically start on the interior of the proximal side and exits on the outside of the distal side of the speculum. Alternate opening shapes are possible, such as designs that widen the proximal end of the speculum while retaining the size of the distal tip. The specula can come multiple shapes including oval, clover, or more. Suction or irrigation specula are disclosed, including some to accommodate suction, irrigation, or endoscopes. Some such specula will include a silicone o-ring that creates a seal within the ear. The specula can include pigtail attachments for the suction and irrigation. An addition specula is on configured for stereoscopy, including with two parallel cameras that allow physicians to perform surgeries in 3D making for faster PDSD No.394.0002WO01 safter surgeries. Physicians can, for example, wear a headset (such as an OculusTMheadset) or 3D glasses to make use of the stereoscopic effect. Various ways of affixing a speculum to an ear are also disclosed, such as holding the speculum still relative to the patient's head. This can be done, for example, by using either staples, ear band, or gown clips.

In an embodiment, further can include ratcheting teeth for holding the diameter of the body. In an embodiment, further can include one or more means to retain the speculum in a patient’s ear. In an embodiment, further can include a saline port. In an embodiment, further can include a suction port. In an embodiment a clip is included having a first portion for securing an endoscope, a second portion for securing to a tool for insertion of ear tubes into a patient. In some embodiments a flexible tip camera is used with a small diameter and high definition resolution. A flexible tip camera allows an angle to better view different areas of an ear canal / tympanic membrane depending on unique ear anatomy. Traditional rigid endoscopes come in 0°, 30°, 45°, and 70° models. The present application allows for 0° flexible endoscope, which can alter the flexible tip dynamically to achieve a range of 0 to 60 degree viewing angles dynamically and with one low-cost flexible camera. The design also allows for a fixed 0° 30°, 60° specialty speculums that may be required with unique ear canal anatomies and four unique ear canal procedures. The present disclosure allows for underwater surgery / ear irrigation / fogging / blood splatter. With modern rigid endoscopes in the ear, they fog up and get dirty with blood splatter or wax. With flexible endoscopes and with our the system of the present application it is possible to integrate irrigation and suction channels into the wall of the speculum. Just as a camera can been mounted on the periphery of the speculum to optimize working space in the inner diameter of the speculum, it is possible to peripherally mount irrigation and suction channels in the speculum. Irrigation and suction channels can allow for underwater visualization of the ear canal. Underwater visualization can eliminate fogging of the camera tip and also eliminate blood splatter which fogs up a camera tip slowing down surgery. Underwater surgery also allows mixing of vasoconstructive substances, like Afrin or epinephrine, or antibiotics into the saline irrigation, which further decreases bleeding, operative time, and surgeon fatigue. In surgery wasted time increases cost, complications, and surgeon fatigue. Underwater surgery can minimize rates of bleeding, infection and even deafness. PDSD No.394.0002WO01 Underwater surgery can also increase surgeries done in the clinic setting avoiding the cost of an operating room. The present disclosure includes embodiments comprising: A camera shaft that is accessed from the outside of the spectrum as opposed to the inside of the speculum. A dual lumen design such that when inserting the speculum the camera / viewing lumen collapses into a working lumen. The working lumen then opens up after insertion and the viewing lumen move to the periphery of the ear canal. This increases working space in the speculum without compromising visualization. In addition to keeping open a viewing port for deeper ear structures, part of the role of traditional rigid ear speculum are to prevent hair or wax from blocking the view through an otoscope or microscope. One hair in the ear proximal ear canal (so between the eyes and the desired deeper ear canal structures) impacts the depth of field of the eyes from the deeper ear canal structures. This need to maintain a viewing port does not require a round / rigid speculum nor is this current design ideal for ear canals that vary in shape (some more slit like, oval or oblong than uniformly round). In certain embodiments instead of using rigid plastic it is possible to use very flexible materials to achieve the function of keeping wax or ear hairs from blocking the field of view. The disclosure is also directed to a soft beveled speculum, including one with a flexible and dynamic function. In some embodiments beveled specs will not be rigid continuous plastic, but will have fingers that flex independently while maintaining rigidity. These flexible fingers in a beveled tip can both increase comfort to patients that are awake and help adapt to each patient's unique ear canal anatomy. In some embodiments the distal tip of the speculum is flared out. This flare will accommodate (with flares of various lengths, angles, rigid fingers, etc. ) the hourglass shape of the medial ear canal. Traditional tapering ear speculum designs are narrowest as the ear canal starts to open up and this minimizes both the viewing window and working window. Operating ear speculums have slightly improved upon viewing ear speculums by making the tip of their speculum beveled (top of speculum is longer than the bottom of the speculum. This bevel effectively increases the viewing and working PDSD No.394.0002WO01 inner diameter. Unfortunately, these beveled operating speculum, are rigid and thus don't increase or decrease in size like the present example speculum. Changing speculums in the operating room increases the cost of equipment needed and adds to the time of surgery. There are cases where ear canal trauma from rigid speculum actually lead the post-operative scarring of the ear canal which would require additional surgical treatment. Additionally, these beveled operating speculum do not have a flared distal tip. A flared distal tip in some situations further improves the operating view of an operating speculum. With a rigid speculum, a flared distal tip would be more prone to cutting and abrading the ear canal, leading to pain, bleeding, and potential infections / scarring. A flared out tip practically needs to be flexible to be used in an awake or sedated patient. In certain embodiments a flexible camera can be affixed centrally (or anywhere else in an ear speculum). The combination of a flexible camera or rigid camera acts to hold the rigid or flexible camera in place. The above-referenced features allow for improved examination and therapeutic treatments, along with improved systems and methods. including assisted imaging and stereoscopy. Also, as noted above, the various features described herein can be incorporated into use for saline field surgery.

Physicians can, for example, wear a headset (such as an OculusTMheadset) or 3D glasses to make use of the stereoscopic effect. Various ways of affixing a speculum to an ear are also disclosed, such as holding the speculum still relative to the patient's head. This can be done, for example, by using either staples, ear band, or gown clips. The above-referenced features allow for improved examination and therapeutic treatments, along with improved systems and methods. including assisted imaging and stereoscopy. Also, as noted above, the various features described herein can be incorporated into use for saline field surgery. Reference will now be made to the figures. FIG.1 is a cross sectional view of the anatomy of human ear, showing a speculum 100 inserted into the ear 110, as well as various internal ear elements. The speculum gives access to the inner ear, with the tip of the speculum extending into the outer ear canal. Also shown in FIG.1 is the ear drum, middle ear, ear ossicles, oval window, round window, vestibule, semicircular canals, cochlea and eustachian tube. FIG.2 is a perspective view of a speculum 200 constructed and arranged in accordance with various embodiments herein, the speculum 200 including a base 210 that is the widest point in the speculum 200, along with a tip 220. The base is on the PDSD No.394.0002WO01 proximal (health care provider) end of the speculum 200 when in use, while the tip 220 is on the distal end of the speculum 200. The tip 220 is inserted into the outer ear of a patient during use. The speculum 200 in FIG.1 includes a slit 230 running along the length of the speculum from the base 210 to the tip 220. The slit 230 allows for the diameter of the speculum 200 to be changed during use, such as by compressing the speculum 200 into a smaller diameter for insertion into a patient’s ear. This allows the speculum 200 to be inserted with less discomfort to a patient, and also allows for insertion into the ear of patients with more narrow outer ear canals. FIG.3 is a perspective view of a speculum 300 constructed and arranged in accordance with various embodiments herein. The speculum 300 includes base 310, tip 320, and also hinge 330.

FIG.43 shows an example specula 4300 with lights 4390 and camera 4392, such as used for augmented reality applications. This design integrates a digital camera into the speculum with lights (which are typically separate). The camera and lights can be mounted in a variety of configurations and locations around the periphery of the inner or outer diameter of the speculum tip. Separating the camera from the lights effectively increases the working distance of the inner diameter of the speculum, which effectively makes it easier to work in tighter spaces. As an example, a typical endoscopic ear camera may be 1.8 mm in diameter with the lights and camera all together. With these individual parts making up the 1.8 mm diameter deconstructed and mounted separately around the periphery of the speculum as opposed to obstructing the interlooming with 1.8 mm diameter in one spot, it is possible divide this obstruction in three separate spots and maximize the functional operating space within the inner diameter. The individual parts of endoscopic camera can be mounted on the inside or outside of the speculum through a channel on the outer or inner area of the speculum or these parts circumferentially enclosed with a cavity built within the structure of the speculum.
