Easy Grip Tapered Dilator
There is provided a device for performing a tracheotomy. The tracheostomy dilator has a body and a tip which are detachably attached. The dilator has a cannula sized to accommodate a guiding catheter. The tip has a proximal inner portion which is within the body while the tip is attached to the body. After the trachea has been dilated, the body may be detached from the tip and removed and a tracheostomy tube may be inserted over the inner portion of the tip. The tip then may serve to guide a tracheostomy tube into the trachea. After the tracheostomy tube is installed, the tip and other components may be withdrawn through the tracheostomy tube and the tracheostomy tube placed in service.
1 . A tracheostomy dilator comprising a body and a detachable tip, said dilator having a cannula, said tip having a proximal inner portion that is within said body while said tip is attached to said body.
2 . The dilator of claim 1 wherein an angle formed by lines from a proximal end of said body and a distal end of said tip is between 110 and 60 degrees.
3 . The dilator of claim 1 wherein an angle formed by lines from a proximal end of said body and a distal end of said tip is between 100 and 70 degrees.
4 . The dilator of claim 1 wherein an angle formed by lines from a proximal end of said body and a distal end of said tip is between 90 and 80 degrees.
5 . The dilator of claim 1 wherein an angle formed by lines from a proximal end of said body and a distal end of said tip is between 110 and 60 degrees.
6 . The dilator of claim 1 having surface formations on the proximal end of said body to enhance the grip of the user.
7 . The dilator of claim 1 further comprising a locking means to hold the tip in place with the body.
8 . The dilator of claim 7 wherein said locking means is at least one notch on the outer surface of the proximal end of said inner portion of said tip, into which fits at least one ridge located on an inner wall on the proximal end of said body.
9 . The dilator of claim 7 wherein said locking means is a one projection on the outer surface of the proximal end of said inner portion of said tip, which is proximal to a slot on the proximal end of said body when said tip is fully in place in said body.
10 . The dilator of claim 1 having a water activated lubricious coating on a surface.
11 . The dilator of claim 1 which changes from relatively very flexible at a distal end to relatively less flexible at a proximal end.
12 . The dilator of claim 1 comprising a guiding line running length-wise on an uppermost surface of said dilator.
13 . The dilator of claim 1 wherein said tip is between 25 and 80 mm in length not including said inner portion which is between 15 and 30 cm and said body is between 12 and 25 cm in length.
14 . The dilator of claim 1 wherein said tip incorporates a guiding catheter.
15 . The dilator of claim 1 wherein said body has a guiding line.
16 . The tracheostomy dilator of claim 1 wherein said tip is adapted to remain in a trachea when said body is removed during a tracheostomy procedure.
