a catheter guiding device 1 that currently exists in the art is depicted in fig1 . a pair of handles 5 , 10 each defines an aperture 2 , 3 for a user to insert a finger and thumb . the handles 5 , 10 are integrally connected to a pair of arms 15 , 20 . the handle 5 and arm 15 is pivotally connected to the handle 10 and arm 20 through a pivot 50 . each arm 15 , 20 has an end 30 , 35 , respectively , that is d - shaped with parallel , sharp serrations on the interior surfaces . when using this device to insert a catheter into a patient , a medical professional will insert his or her fingers into the apertures 2 , 3 and open the handles 5 , 10 , which correspondingly open the arms 15 , 20 . the health care professional will then close the handles 5 , 10 , accordingly closing the arms 15 , 20 , so that the ends 30 , 35 grip the catheter . the device 1 is then used to push the catheter through the patient &# 39 ; s vocal cords to allow ventilation or to insert the catheter into any other part of the patient &# 39 ; s body as deemed necessary by the medical professional . the device 1 does not allow for guiding of the catheter because the ends 30 , 35 must grip the catheter and are used to push the catheter a short distance , which is repeated numerous times so as to advance the catheter . further , because of the presence of his or hand due to the bent section 60 of the device 1 , the medical professional using the device 1 will be blocked from viewing of the patient &# 39 ; s vocal cords or other body part into which the catheter will be inserted . the present invention can be more fully understood with reference to fig2 - 11 , in which like reference numerals designate like items . fig2 depicts the forceps 101 , which is an improvement over the device 1 currently in use . the pair of handles 105 , 110 of the forceps 101 each defines a gripping section 102 , 103 , respectively , upon which the medical professional can place his or her fingers to use the forceps 101 . gripping sections 102 , 103 can be of any shape . the shape shown is only illustrative . the handles 105 , 110 are integrally connected to a pair of arms , 115 , 120 . the handle 105 and arm 115 is pivotally connected to the handle 110 and arm 120 at a pivot 150 . each arm 115 , 120 has an end 130 , 135 , respectively , that is substantially semicircular in shape ; however , the shape of the ends 130 , 135 may , within the scope of the invention , be any shape that would allow the ends 130 , 135 to form a guide when in the closed position such that a catheter may be easily passed therethrough . when the arms 115 , 120 are in the closed position as shown in fig2 and 4 - 7 , the ends 130 , 135 together form a hollow guide adapted to receive and guide the catheter so that the catheter can be advanced through the patient &# 39 ; s vocal cords . in the closed position , the interior surface of the hollow guide formed by the ends 130 , 135 is preferably slightly larger than 8 mm across , which is slightly larger than the diameter of a standard - sized catheter used for medical purposes today . it is understood that the size of the guide formed by the ends 130 , 135 may be varied within the scope of this invention depending upon the diameter of the catheter , including but not limited to catheters that are used in infant patients . all that is required is that the catheter be able to be slid or translated within the guide when the guide is in the closed position . when using this device to insert a catheter into a patient , a health care professional will insert his or her fingers into the apertures 102 , 103 and open the handles 105 , 110 , which correspondingly open the arms 115 , 120 . fig3 depicts the forceps 101 in the open position . the catheter is then inserted through the circular aperture defined by the ends 130 , 135 of the arms 115 , 120 . the arms 115 , 120 are positioned so that the guide is placed in registry with the patient &# 39 ; s glottis ( the opening in the vocal cords ) so that the catheter can be accurately inserted into the proper location in the patient &# 39 ; s body , such as through the patient &# 39 ; s vocal cords . the first bend 140 and the second bend 145 allow the medical professional to have an unobstructed view of the patient &# 39 ; s vocal cords or other body part into which the catheter is to be inserted . this allows for faster and more accurate insertion of the catheter , without the risk of harm to the patient or damage to the catheter that arises when the medical professional must grip and re - grip the catheter as with currently - available devices , such as the device depicted in fig1 . fig4 depicts the forceps shown in fig2 from the top . the first bend 140 , second bend 145 , and third bend 147 are clearly visible from this view . the combination of the first bend 140 and second bend 145 provides the medical professional with an unobstructed view of the patient &# 39 ; s vocal cords because the user &# 39 ; s hand that holds the forceps is off to the side of the mouth while the guide is in registry with the glottis . the third bend 147 contributes to the unobstructed view of the patient &# 39 ; s vocal cords . the first bend 140 is bent about an axis a to create an obtuse angle . the second bend 145 is bent about an axis b to create an obtuse angle that is preferably , but not necessarily , approximately 120 °. the third bend 147 is bent about an axis c to create an obtuse angle that is preferably , but not necessarily , approximately 150 °. fig5 is a right side view of the forceps shown in fig2 . the arms 115 , 120 and the ends 130 , 135 are smooth , having no sharp edges or teeth that could harm a patient &# 39 ; s tissue or damage the balloon portion of a catheter . an alternative embodiment of the forceps 201 is depicted in fig6 . the pair of handles 205 , 210 of the forceps 201 each defines an aperture 202 , 203 through which the medical professional can insert his or her fingers to use the forceps 201 . the handles 205 , 210 are integrally connected to a pair of arms 215 , 220 . the handle 205 and arm 215 is pivotally connected to the handle 210 and arm 220 at a pivot 250 . each arm 215 , 220 has an end 230 , 235 , respectively , that is substantially semicircular in shape ; however , the shape of the ends 230 , 235 may , within the scope of the invention , be any shape that would allow the ends 230 , 235 to form a guide when in the closed position such that a catheter may be easily passed therethrough . when the arms 215 , 220 are in the closed position as shown in fig6 , the ends 230 , 235 together form a hollow guide adapted to receive and guide the catheter so that the catheter can be advanced into the patient &# 39 ; s glottis . in the preferred embodiment , when the arms are in their closed position , the interior surface of the hollow guide formed by the ends 230 , 235 is preferably slightly larger than 8 mm across , which is slightly larger than the diameter of a standard - sized catheter used for medical purposes today . it is understood that the size of the guide formed by the ends 230 , 235 may be varied within the scope of this invention depending upon the diameter of the catheter , including but not limited to catheters that are used in infant patients . the forceps 201 has a first bend 240 and a second bend 245 that together allow the medical professional to have an unobstructed view of the patient &# 39 ; s glottis and vocal cords or other body part into which the catheter is to be inserted . the difference between the forceps 101 and the forceps 201 is that the forceps 201 has a fourth bend 280 located immediately before the ends 230 , 235 . the fourth bend 280 rotates the ends 230 , 235 approximately fifteen degrees clockwise from their standard position , although a greater or lesser magnitude of bend may be desirable as will occur to the person of skill in the art . also , the bend 280 may be as shown ( acute ) or may rotate the ends 230 , 235 in the opposite direction , creating an obtuse angle . the angle of insertion of a catheter through the ends 230 , 235 is changed by the fourth bend 280 , allowing for an easier insertion in patients that have a shorter neck , such as children or small adults . it is understood that the degree of the angle of the fourth bend 280 may vary according to the needs of a particular situation within the scope of this invention . fig7 through 9 illustrate the use of the forceps 101 and a laryngoscope 450 in a patient . nasal endotracheal intubation is illustrated in fig7 , wherein a ventilation tube 400 is inserted into the patient &# 39 ; s nose and passed through the patient &# 39 ; s sinus cavity into the back of the patient &# 39 ; s throat . a laryngoscope 450 is used to secure the patient &# 39 ; s tongue and provide light to the patient &# 39 ; s throat . as the medical professional holds the forceps 101 in registry with the patient &# 39 ; s glottis 500 , a medical assistant , such as a nurse , will advance the ventilation tube 400 through the ends 130 , 135 of the forceps 101 and through the patient &# 39 ; s glottis 500 . after being properly located , the balloon portion 420 of the ventilation tube 400 is inflated to secure a seal and allow for proper ventilation . an alternative embodiment of the forceps 601 is depicted in fig1 . the pair of handles 605 , 610 of the forceps 601 each defines an aperture 602 , 603 through which a medical professional can insert his or her fingers to use the forceps 601 . the handles 605 , 610 are integrally connected to a pair of arms 615 , 620 , respectively . the handle 605 and arm 615 is pivotally connected to the handle 610 and arm 620 at pivot 650 . each arm 615 , 620 has an end 630 , 635 , respectively , that is substantially shaped as half of a cone ( or , alternatively , as half of a cylinder ); when the arms 615 , 620 are in the closed position as shown in fig1 , the ends 630 , 635 together form a cone - shaped ( or cylindrically - shaped ) guide adapted to receive and guide a catheter so that the catheter can be advanced into the patient &# 39 ; s glottis . the diameter of the cone - shaped ends 630 , 635 , when closed , is preferably slightly larger than 8 mm across at its narrowest point . the portion of the ends 630 , 635 that is closer to the handles 605 , 610 preferably has a diameter larger than 8 mm . in the closed position , the interior surface of the hollow guide formed by the cone - shaped ends 630 , 635 acts as a funnel of sorts to allow the medical professional to more easily guide the end of a catheter through the cone - shaped ends 630 , 635 . it is understood that the size of the guide formed by the ends 630 , 635 may be varied within the scope of this invention depending upon the diameter of the catheter , including but not limited to catheters that are used in infant patients . the forceps 601 has a first bend 640 and a second bend 645 that together allow the medical professional to have an unobstructed view of the patient &# 39 ;
