BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to a reusable sinus dilation instrument and method of use, and more particularly to a reusable sinus dilation instrument having a guide seeker constructed from a sterilizable material with a bended terminal end offset from an attachment terminal end and a central grip intermediate of the terminal ends, and having a removable handle capable of being attached to the attachment terminal end at a predetermined orientation relative to the bended terminal end of the guide seeker.
2. Description of the Related Art
Sinus disease often occurs because of blockage. The blockage traps mucous in a warm, moist environment and can produce infection. Blockage also allows pressure to build which can cause pain and pressure over the sinus cavities. Balloon sinuplasty is a newer less invasive operation to correct sinus disease. During the procedure, no mucosal tissue is removed, rather the ostia or opening on the sinus is enlarged by inserting a balloon that is inflated. The opening then heals in the open position. Balloon sinuplasty overcomes the infection, pain, and pressure by keeping the sinus ostia open.
Current medical-grade instruments used in balloon sinuplasty have a high cost because most of the parts are intended for one time only use. There are less expensive instruments, but those instruments have problems with bulk and awkward angles, which make these instruments very difficult to use and can cause more tissue trauma, which may lead to more scarring and revisions.
It is therefore desirable to provide an improved reusable sinus dilation instrument and method of use.
It is further desirable to provide a reusable sinus dilation instrument that can be safely sterilized, has better angles for finding the sinus, and has less profile so as to cause less tissue trauma.
It is still further desirable to provide a reusable sinus dilation instrument having a guide seeker and a disposable balloon capable of being slipped over the guide seeker.
It is yet further desirable to provide a reusable sinus dilation instrument having a guide seeker with a bended terminal end offset from an attachment terminal end and a central grip intermediate of the terminal ends.
It is still yet further desirable to provide a reusable sinus dilation instrument having a removable handle capable of being attached to an attachment terminal end at a predetermined orientation relative to a bended terminal end of a guide seeker of the instrument.
It is yet further desirable to provide a reusable sinus dilation instrument where the angle of the terminal bend varies depending on the sinus being treated, e.g., about 45 degrees for frontal, about 95 degrees for maxillary, and about 10 degrees for sphenoid sinus.
It is still yet further desirable to provide a reusable sinus dilation instrument having a fiber optic cable in the center of the guide seeker.
It is still yet further desirable to provide a reusable sinus dilation instrument made of sterilizable material, e.g. stainless steel.
It is still yet further desirable to provide a reusable sinus dilation instrument having a removable handle capable of being attached to the instrument using a luer taper fitting, a threaded attachment or other attachment means.
Other advantages and features will be apparent from the following description and from the claims.

Referring to the figures of the drawings, wherein like numerals of reference designate like elements throughout the several views, and initially to FIGS. 1 through 7, a reusable sinus dilation instrument 10 has a guide seeker 12 constructed from a sterilizable material, such as stainless steel. The guide seeker 12 includes a bended terminal end 14 offset from an attachment terminal end 16 and a central grip 18 intermediate of the terminal ends 14/16. The instrument 10 also includes a removable handle 20 capable of being attached to the attachment terminal end 16 at a predetermined orientation relative to the bended terminal end 14 of the guide seeker 12.
As exemplified in FIGS. 1 through 3 and 5 through 7, the guide seeker 12 is a frontal sinus guide seeker 12 with the removable handle 20 oriented generally coplanar with and parallel to the bended terminal end 14 of the guide seeker 12. The bended terminal end 14 of the frontal sinus guide seeker 12 may have an angle A of about 45 degrees with a long gentle curve of approximately 2.5 cm in length L1. A tip 22 of the curve of the bended terminal end 14 may be approximately 1 mm diameter and progressively enlarge to about 2 mm in diameter over a length L2 of about 8 cm. The length L3 of the central grip 18 of the guide seeker 12 continues the diameter of approximately 2 mm to the attachment terminal end 16 of the guide seeker 12.
The removable handle 20 of the instrument 10 is capable of being attached to the attachment terminal end 16 at a predetermined orientation relative to the bended terminal end 14 of the guide seeker 12. The handle 20 of the instrument 10 may increase in diameter to about 5 mm and be about 2 cm in length L4. Similarly to the guide seeker 12, the handle 20 may be constructed of a sterilizable material, such as stainless steel. As depicted in the figures, namely FIG. 4, the handle 20 is coupled to the attachment terminal end 16 of the guide seeker 12 using a threaded attachment mechanism 24; however, the invention is not so limited as the handle 20 can be attached to the instrument 10 using a luer taper fitting or other suitable attachment means. The handle 20 may include a wing 26 attached to and protrude away from a body 28 of the handle 20. The wing 26 may be about 2 mm thick, about 3.5 cm long and about 2 cm wide, resulting in the instrument 10 having a length of about 23 cm from the tip 22 of the bended terminal end 14 of the guide seeker 12. As illustrated in FIGS. 1 through 3 and 5 through 7, the handle 20 is oriented generally coplanar with and parallel to the bended terminal end 14 of the front sinus guide seeker 12. Alternatively as illustrated in FIGS. 12 and 13, the handle 20 may be selectively attached to the attachment terminal end 16 of the guide seeker 12 such that the wing 26 of the handle 20 projects in a direction opposite of the curve of the bended terminal end 14 of the guide seeker 12.
As can be seen in FIGS. 5 through 7, a disposable balloon 30 may be slipped directly over the guide seeker 12 and does not have to be removed or advanced, although the balloon 30 could be advanced if needed. The balloon 30 may be about 6 mm in diameter and about 18 mm long. The balloon 30 is positioned along the length L1 of the gentle curve of the bended terminal end 14, with a leading end 32 positioned about 1 mm from the tip 22 of the bending terminal end 14 and a terminal end 34 positioned along length L2 of the central grip 18 of the guide seeker 12. As illustrated in FIG. 5, the balloon 30 is slipped over the bended terminal end 14 of the guide seeker 12 while in FIG. 6 the balloon 30 is slipped over the attachment terminal end 16 of the guide seeker 12. Once the balloon 30 is seated over the guide seeker 12 as depicted in FIG. 7, a suitable air supply (not shown) may be fluidly coupled to an attachment mechanism 36 of the disposable balloon 30.
Referring now to FIGS. 8, 9 and 14, the reusable sinus dilation instrument 10 includes a maxillary sinus guide seeker 12 having the bended terminal end 14 with a rounded approximately 95 degree angle A. Similarly to the front sinus guide seeker discussed above, the bended terminal end 14 of the maxillary sinus seeker 12 may be approximately 8 mm in length L1 from the central grip 18. The diameter of the bended terminal end 14 is about 1 mm and progressively increases to about 2 mm in diameter for a length of about 8 cm along the central grip 18 of the guide seeker 12. The handle 20 is coupled to the attachment terminal end 16 of the guide seeker 12 and increases the diameter to about 5 mm and is about 2 cm in length. The wing 26 of the handle 30 may be about 2 mm in thickness, about 3.5 cm long, about 2 cm wide and about 23 cm from the tip 22 of the bended terminal end 14 of the guide seeker 12. As shown in FIG. 14, the handle 20 is disposed generally perpendicular to the bended terminal end 14 of the guide seeker 12. Although the handle 20 is exemplified as having a single wing 26 attached to and projecting from the body 28 of the handle 20, the handle 20 can include two (2) opposing wings 26 affixed to and protruding away from the body 28, and in such an embodiment, each of the wings 26 would be oriented generally perpendicular to the angle A of the bended terminal end 14 of the guide seeker 12.
Referring now to FIGS. 10 and 11, the reusable sinus dilation instrument 10 includes a sphenoid sinus guide seeker 12 having the bended terminal end 14 with a gentle curve having an approximately 10 degree angle A. The gentle curve may measure about 1 cm long and about 2 mm at the tip 22 of the bended terminal end 14 of the guide seeker 12. The diameter can be about 2 mm for a length of about 8 cm, and then increase to about 5 mm in diameter for about 2 cm in length. The wing 26 and the handle 20 of the sphenoid sinus guide seeker 20 may be configured and oriented similarly to the frontal sinus guild seeker 12, namely, the handle 20 is oriented generally coplanar with the bended terminal end 14 of the front sinus guide seeker 12. In addition, the handle 20 may be selectively positioned such that the wing 26 of the handle 20 is parallel to the bended terminal end 14 of the front sinus guide seeker 12 or such that the wing 26 of the handle 20 projects in a direction opposite of the curve of the bended terminal end 14 of the guide seeker 12.
Additionally, the handle 20 of the reusable sinus dilation instrument 10 may be specifically constructed for left or right sinus cavity procedures, and could be made with one wing 26 or with two (2) opposing wings 26. The balloon 30 may also have a locking mechanism (not shown) onto the handle 20, along with smaller wings 26 to allow advancement if needed.
The reusable sinus dilation instrument 10 may include a fiber optic element (not shown) embedded within a center channel (not shown) of the guide seeker 12 allowing the practitioner to confirm positioning and placement of the balloon 20 in the sinus cavity using transdermal illumination. With embedded fiber optics, the diameter of the tip 22 at the bended terminal end 14 of the guide seeker 12 increase to about 2 mm.
Whereas, the instruments and methods have been described in relation to the drawings, it should be understood that other and further modifications, apart from those shown or suggested herein, may be made within the scope of this invention.
