This invention relates generally to the field of medical devices to be used for removing foreign objects from small anatomical spaces. More specifically, the invention is directed towards a device and methods for removing foreign objects from the external ear canal or the nasal cavity.
Each year, physicians see thousands of children for foreign bodies located in their ear canal or nasal cavity, and in many cases these objects cannot be removed using the current standards of care. It is estimated that foreign body extraction from a child's ear canal accounts for approximately 1 in every 500 emergency room (ER) visits. See Schulze S L, Kerschner J, Beste D, Pediatric external auditory canal foreign bodies: a review of 698 cases. Otolarngol Head Nick Surg 2002; 127: 73-78. Common devices used include alligator forceps, Frazier tip suctions, cerumen loops, right angle ball hooks, and Hartman forceps. In one study, spherical objects only had a 51% successful removal rate by pediatricians. In addition, non-graspable foreign objects are also more common than graspable objects. See DiMuzio J, Deschler D, Emergency Department Management of Foreign Bodies of the External Ear Canal in Children, Otol & Neurotol 2002; 23: 473-5.
Existing devices are not only unsuitable for removing spherical bodies, but can also be dangerous to a child's ear canal. The most common methods of removing foreign bodies from the ear canal or nasal cavity are through the use of forceps (alligator and Hartman), balloon catheters, suction, and irrigation. Alligator forceps look like scissors except they contain very small pincers on the end of a thin metal rod. Hartman forceps are similar to alligator forceps, but the end has the appearance of tweezers. Both alligator forceps and Hartman forceps may be used for removing foreign bodies that are graspable or have edges, such as paper or insects; however, they cannot grip small, spherical objects. The sharp edges of the forceps can damage the ear canal or tympanic membrane, posing additional risks. See Kadish H, Ear and Nose Foreign Bodies: “It is All About the Tools,” Clin Pediatr 2005; 44: 665-70. Another less commonly used device is the Katz extractor that works similar to a catheter. First, a deflated balloon is inserted into the ear canal so that the tip extends beyond the foreign object. The physician then depresses a bulb in order to inflate the balloon tip. The balloon is then pulled to dislodge the object and guide it out from within the ear canal. U.S. Pat. No. 5,454,817 teaches a balloon catheter. This Katz method can be effective to some extent, but it will not work if the catheter tip cannot get past the foreign body, which is often the case in a child's narrow ear canal. The risk of damaging the tympanic membrane stills exists with the Katz extractor. See DiMuzio J, Deschler D, Emergency Department Management of Foreign Bodies of the External Ear Canal in Children, Otol & Neurotol 2002; 23: 473-5.
Irrigation and suction are also common removal methods. However, both methods pose danger to the sensitive tympanic membrane of a young child. Suction is useful for removing foreign bodies, especially those that are light, hard and spherical, but it loses effectiveness in the narrower, medial two thirds of the ear canal. The loud sound of the suction can also be aggravating or traumatizing to pediatric patients. Furthermore, suction is usually only operable by otolaryngologists and seldom by the ER or pediatricians. See Kadish H, Ear and Nose Foreign Bodies: “It is All About the Tools,” Clin Pediatr 2005; 44: 665-70. Irrigation of the ear canal is another possible technique to remove spherical objects that cannot be grasped by forceps or suction. However, if the object absorbs the irrigation solution, it becomes even more difficult to remove. In addition, if the irrigation pressure is too high, practitioners also run the risk of rupturing the tympanic membrane. See Kadish H, Ear and Nose Foreign Bodies: “It is All About the Tools,” Clin Pediatr 2005; 44: 665-70. The ER or the pediatricians' offices are also usually not equipped with the suction or irrigation apparatus. The patient must be referred to an otolaryngologist when a pediatrician or ER physician is unsuccessful at removing the object, and often, a surgical procedure is necessary. Overall, current standards of care are not sufficient for the removal of all foreign bodies. Despite continued efforts to develop new products in this field, this problem has not been effectively addressed.
Certain swab-like devices are used for the removal of cerumen from the ear canal. See, for example, U.S. Pat. No. 8,551,031 and U.S Patent Application 2008/0208100. However, these devices are better suited for removing cerumen, which is a waxy type of substance secreted by glandular cells in the ear canal of the human body, and do not adequately remove small spherical foreign objects, such as beads. Firstly, swab-like devices usually are designed with a dimension that prevents the user from inadvertently advancing the tip of the device to the medial ear canal. As a result, such devices will not be useful in retrieving a foreign object that is lodged at the narrowing section of external ear canal, called the bony-cartilaginous junction, or beyond the bony-cartilaginous junction to the medial two third of the ear canal, the osseous portion of the ear canal. They will also not leave any space to allow visualization of the external ear canal when the tip of the swab-like device is inside the external ear canal. Furthermore, such devices will be too large to be able to pass through a speculum and thus cannot be used in combination with a speculum or an otoscope. Secondly, the size of the swab-like device makes it virtually impossible for the swab-like device to not touch the wall of the external ear canal. While it is an objective of a swab in the prior art to contact the wall of the external ear canal to dislodge the cerumen that is stuck on the wall, it is undesirable for the adhesive on a device that is intended for removal of a foreign object to make contact with the wall of the external ear canal before it reaches the foreign object. Thirdly, most of the swab-like devices in the prior arts are of a straight elongated shaft and the user's hand will be blocking the line of vision of the user into the ear canal. Still, the size of the swab makes it difficult to have direct visualization of the ear canal. Furthermore, the swab-like devices do not provide features that safeguard against tremor of the user's hand.
Finally, Japanese Patent 2004194859 (as best as can be determined by available machine translation) apparently teaches a removal tool that has several disadvantages. The tool requires the use of a pair of tweezers to be advanced into the ear canal, adding complexity to the removal procedure. The tweezers, like the swab-like devices, also lacks features that minimize tremor of the user's hand. The tassel lacks rigidity and makes it inevitable that the adhesives on the tassel would make contact with the wall of the external ear canal. The adhesive applied on the tassel also requires additional curing time, making this invention impractical to be used with a child.
In summary, there is still a need for a device that allows for speedy and efficient removal of foreign bodies (or objects) stuck inside the external auditory canal, especially of a child patient, in an outpatient setting, where suction and irrigation tools are not readily available, and minimizes the chance of causing trauma to the auditory canal or the tympanic membrane when using the device.
As set out in further detail below, an aspect of an embodiment of the present invention provides, among other things, a low-cost device (and related method) for removing foreign bodies (or objects) using an adhesive. An aspect of an embodiment of the present invention provides, but not limited thereto, a device comprising an elongated member having a first portion, a second portion with a distal end, and a fulcrum disposed along the elongated member between the first portion and the second portion. Furthermore, the device has a distinct bend, forming an offset angle between the first portion and the second portion. The distal end of the second portion comprises further a rounded tip and an adhesive portion. The device is intended to be inserted into the external ear canal and advanced incrementally until the foreign body (or object) adheres to the distal end of the second portion of the device. No curing time is required for the foreign body to adhere to the device. The device can then be withdrawn from the ear canal with the foreign body (object) attached to it. This device can be used by any medical professional in the Emergency Department (ED), a Pediatrics clinic, Family Medicine clinic, or an Otolaryngology clinic. The device may specialize in the extraction of non-graspable, spherical objects, and therefore provides advantages and unique features over conventional approaches. Accordingly, an embodiment of the present invention can be also be used in the removal of non-spherical objects, which gives it all-around utility.
In one embodiment, the device is of a small profile such that it can be inserted deeper than a swab-like device, and the tip of the device can reach the narrowing section of the external ear canal, the bony-cartilaginous junction, without making inadvertent contact with the wall of the external ear canal. In one embodiment, the tip of the device can reach the region of the external ear canal at the anterior tympanic sulcus, without making inadvertent contact with the wall of the external ear canal or with the tympanic membrane.
In one embodiment, the offset angle of the device allows visualization of the foreign body when it is being removed by the device. The device may be inserted into the ear canal with or without the aid of a speculum. The small profile and the distinct bend clear the path for a light source to provide better visualization of the foreign body while it is being removed by the device. The device may also be used in combination with an otoscope and a speculum if enhanced visualization is required.
In one embodiment of the present invention, the device has a finger support surface, such as a thumb loop (or solid thumb hold or thumb plate), which allows the practitioner to fulcrum the device against the thumb, as it is held between the thumb and the first three fingers, for instance. The finger support surface allows the practitioner to hold the device steadily to minimize tremor in the user. When held this way, the practitioner can also rest the hand against the patient's head further stabilizing the device and hand. Also, when held in this manner, if the patient or subject moves, the hand of the practitioner and device can move with the patient, minimizing traumatic injury to the ear canal. In an embodiment, the finger support surface also gives haptic feedback (tactile feedback) to the practitioner so he/she can “feel” when the end of the device makes contact with the foreign body. In an embodiment, the thumb loop, thumb hold or thumb plate allows better grip and balance of the device during the foreign body removal rather than attempting to grip the instrument at the other parts of the device.
In summary, an aspect of various embodiments of the present invention may provide a number of advantages, such as but not limited thereto, the following: i) the inexpensive cost to manufacture and maintain the device; ii) the device's special ability to extract spherical objects from the ear canal using an adhesive, making it available for use in the emergency room, family medicine, and pediatric offices, which do not have suction and other equipment; iii) the rounded tip of the device to minimize inadvertent damage to the wall of the external ear canal and to maximize the surface area of the adhesive; iv) the small profile of the device allowing it to go deeper than a swab-like device and also to prevent inadvertent contact of the device with the wall of the external ear canal; v) the small profile of the device to allow visualization of the foreign body being removed; vi) the device having a distinct bend or contour to get the user's hand out of the way to provide visualization of the foreign body; vii) a fulcrum with a finger support surface to stabilize the practitioner's hand and enabling the practitioner's hand to rest on the patient's head; vii) the finger support surface providing haptic feedback when it makes contact with the foreign body; viii) the flexibility of using the device with or without a speculum or an otoscope; and ix) the adhesive not requiring curing time and thus aiding in speedy removal of the foreign body.

For the purpose of prototype testing of an embodiment of the present invention, the present inventors narrowed the maximum weight that the adhesive could hold for 12 seconds (approximately equal to the average extraction time for the slowest user in our time trial test, plus one standard deviation). The adhesive was capable of holding 40 grams for 12 seconds without deforming (stretching), and 140 g for 12 seconds with moderate deformation. These masses are orders of magnitude greater than the mass of an average bead or popcorn kernel, so the adhesive demonstrated strength and reliability far beyond its normal operating range.
