A. SOLO SEPTUM SPLINT Filed April 25, 1938 3 Sheets-$h 5 Patented May 28, 1940 UNlTED STATES PATENT OFFICE 2 Claims.
This invention relates to a septum splint, the general object of the invention being to provide an instrument for molding the nasal septumi straight. It is mainly designed to be used in the nose following the operation of sub-mucuous resection or in traumatic conditions wherein it is desirable to bring into contact or approximation the layers of the nasal septum. It is designed so as to permit freedom of breathing space and an adequate airway after its insertion. I
Another object of the invention is to make the instrument adjustable for different sizes of noses, though it may be made in different sizes to fit different sized and shaped noses.
The invention also consists in certain other features of construction, combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing the invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which- Fig. l is a top view of the invention.
Fig. 2 is a bottom view thereof.
Fig. 3 is a side view with the rubber sheath in section.
Fig. 4 is a side view with the sheath in section and the parts in open or expanded position.
' Fig. 5 is a section on line 55 of Fig. 3.
Fig. 6 is a section on line 6-6 of Fig. 3.
Fig. 7 is a view of the four movable blades 3; separated.
In these drawings, the Letters A and B in dicate a pair of members which form the instrument and each of which includes a body member I of elongated form and having one side extended to form a stationary blade 2. The members are made right and left and the blade extends from the outer side of the body member and each blade curves inwardly, at its inner portion, as shown. The two body members are connected together by the inner and outer screws 3 and 4. The outer screw engages threaded hole in one body member and has a reduced unthreaded part 3', adjacent its head, which fits in an unthreadcd hole in the other body member, as shown in Fig. 50 6'. Thus the two members can be adjusted towards and away from each other and then by tightening the screw 3 the two members are locked in adjusted position. Each body member is formed with a. depending part I which is formed with a threaded longitudinally extending hole which opens into a horizontal slot 1 which passes through the sides of the part I and slidingly receives a cam 8, which is held in. place by having a head at one end and a washer 9 engaging the other end and also engaging portions of the part I and is held in place by a screw I0, as shown in Fig. 5. Four movable blades l I, preferably of the shape shown in Fig. '7, have their inner ends pivoted in the inner end of the upper part of a vertical slot 12, formed in the inner end of the body member.. The pivot is shown in the drawings as a screw pin [3, see Fig. 5. Each blade II is formed with a depending lug l4 adjacent its pivoted end and the cam is so formed that as it engages the lugs it will spread the four blades into substantially fan shape, as shown in Fig. 4. The cam is moved into engagement with the lugs by a screw l5 which engages the aforesaid threaded hole in the outer end of the part I. A sheath l6, formed of rubber or the like, encloses the five blades, and, of course, this sheath is stretched by the outward movement of the blades, as also shown in Fig. 4. When the screw i5 is backed from the cam the sheath causes the movable blades to go back to their original positions, as shown in Fig. 3. This sheath is omitted in Fig. 1- and 2. Thus it will be seen that the two members A and B can be adjusted towards and away from each other to suit the particular nose with which it is to be used and then after the blades are inserted in the nostrils, the screws 15 are turned inwardly to cause the cams to engage the lugs of the movable blades to cause them to move outwardly into fan shape so as to expand the nasal passages. The sheaths protect the nasal mucosa from damage. When in position in the nose, the instrument is held in place by the two members A and B being held together by the opposed thumb screws 3 and 4.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction, combination and arrangement of the several parts, provided such changes fall with the scope of the appended claims.
What I claim and desire to protect by Letters Patent is:
1. A device of the class described comprising a pair of body members, oppositely arranged screws engaging holes in the two members-for adjusting them-towards and away from each other, a stationary blade extending from the outer side of each member, blades pivoted to each member, a
cam carried by each member and engaging parts of the pivoted blades for moving them outwardly into fan shape, and a screw engaging a threaded hole in each member for moving the cam against said parts of the blades.
2. A device of the class described comprising a pair of body members, oppositely arranged screws engaging holes in the two members for adjusting them towards and away from each other, a static-nary blade extending from the outer side of each member, blades pivoted to each member, a cam carried by each member and engaging parts of the pivoted blades for moving them outwardly into fan shape, a screw engaging a threaded hole in each member for moving the cam against said parts of the blades, and a resilient sheath enclosing the blades of each member.
