CORNEOSCLERAL SUTURING FORCEPS Filed July 5, 1956 INVENTOR i/flgifiE-s (8 49%- BY United States Patent CORNEOSCLERAL SUTURING FORCEPS Wesley c. Thomas, Brunswick, Ga. Application July 5, 1956, Serial No. 595,974 8 Claims. (31. 128-334) My invention relates broadly to' surgical instruments and more particularly to a forceps for corneal or'scleral suturing.
One of the objects of my invention is to provide, a construction of forceps particularly adapted for use in eye surgery in facilitating corneal or scleral suturing.
Another object of my invention is to provide a construction of corneoscleral suturing forceps for facilitating the closing of an incision where the surgeon is provided with reliable means for gripping and stabilizing the cornea or sclera while the suturing needle is guided through the coaptation margin of the cornea or sclera and prevented from penetrating too deeply in the thickness of the cornea in performing the suturing operation.
Still another object of my invention is the production of a construction of suturing forceps in the form of tongs having coacting termini developed particularly for gripping and stabilizing the margins of the lips of a Corneal or scleral incision while performing a suturing operation as set forth more fully in the specification hereinafter following by reference to the accompanying drawings, in which:

Fig. 11 is a plan view showing the termini of the tongs in superimposed relation, the view being taken from the exterior of the lower jaw of the tongs; and
Fig. 12 is a plan view of the termini of the tongs viewed from the reverse side of the tongs with respect to the view illustrated in Fig. 11
My invention is directed to a construction of corneoscleral suturing forceps for use by eye surgeons in closing injuries and surgical incisions in the eyeball. In closing wounds in the eyeball the stitches must not go through the entire thickness of the retaining structure of the eye- ICC ball, as is the custom in closing skin wounds. 'In closing openings in the eyeball the needle must enter the coaptation surface near its middle so that when coapta-' tion is completed the retaining stitch is at no point inside the globe.
The tongs of the forceps terminate in a pair of coacting blades one of which consists of a pair of spaced tines and the other of which consists of a fiat pallet. The pallet extends from the lower jaw of the tongs while the tines extend from the upper jaw of the tongs. The pallet extends from the lower jaw to a transverse offset shoulder providing an abutment above the surface of the pallet of the upper tines 4 lower jaw 2 and.
on which the peripheral margin of the lip of thecornea or sclera incision may be supported and grasped by the coaction of the tines on the coacting jaw of the tongs. This offset allows only half of the margin of the cornea or sclera which is grasped with the forceps to be seen and the needle sliding along the surface of the pallet or blade must enter the proper place in the coaptation area. The terminal 3 mm. of this pallet or blade is about /2 mm. thinner than'the rest of the blade. The
dividing line between these two sections is the offset previously mentioned. The upper blade of the instrument I has two tines /2 mm. wide, 8 mm. long and 1% mm. apart. The margin of the wound is grasped in such a way that the coaptation edge lies against the offset of the plane blade and the blade of two tines is outside. The
needle passes between the tines along the surface of the plane blade and at the offset enters the margin of the wound at the proper depth. i
The tines carry markers or indicators thereon which correspond in position to the offset in the lower jaw so that when the pallet or blade of the lower jaw is obscured by entry beneath the lip of the cornea the surgeon at all times is aware of the extent ofprojection of the blade of the lower jaw beneath the cornea or sclera by observing J the relationship of .the markers or indicators on the tines of the upper jaw with relation to the peripheral edge of the lip of the cornea or sclera. The pallet or blade of the lower jaw is slightly narrower than the overall width of the tines on the upper jaw for insuring more reliable gripping and stabilization of the lip of the cornea or sclera without injury to the wound.
Referring to the drawings in more detail, the corneoscleral suturing forceps comprise the tweezers or tongs having upper and lower arms or jaws 1 and 2 connecting through the junction 3. The upper jawl terminates in the spaced tines 4 and 5 formed by the bifurcation in the upper jaw 1, centered therein at 6. The tines 4 and 5 of upper jaw 1 are curved ,toward the terminus of the terminate in noses or projections 7 and 8, respectively. The tines 4 and 5 are provided with transverse V-shaped notches or markers 9 and 10 on the exterior sides of the tines as shown more clearly in Figs. 6, 8, 10, and 12.
The lower jaw 2 terminates in a pallet or blade. 11 which is spaced from the lower jaw 2 by a shoulder or; transverse ridge 14. The pallet or blade 11 has a rounded terminus 15. As represented in-Fig. 11 the pallet or blade 11 has a width less than the overall transverse width and 5. slightly beyond the terminus of the pallet or blade 11 as represented at 7 and 8 in Fig. 11.
In Fig. 12 I have shown more clearly the fact that the V-shaped notches or markers 9 and 10 in the tines 4 and 5 are aligned laterally with the transverse offset 12 and ridge 14, whereby the notches or markers 9 and 10 serve as measuring means to enable the surgeon to precisely gage the position of the blade or pallet 11 when inserted beneath the cornea in the process of a suturing operation.
right hand marginal lip. 17 of, the cornea. or sclera. The suturing thread is indicated atv 20 connected at one-end with curved needle 18 and at the other end with curved needle. 19. i
I In the operation depicted in Fig. 3, the lip of the corneal incision 16 is supported .on the pallet or blade 11 with the coaptation margin inabutment withv the offset of shouler 12,0fv the. lower jaw 2. The dimensional depth ofv the offset 12; is such that the thickness dimension of the marginal lip-of the cornea or sclera projects substantially above ther-idge1'4. Nosesor termini 7 and 8' of tines 4 and S rnaintain the marginallip of the; cornea 16, in such position. that thecurvedneedle 18 connected with thread 20 may be passed through the edge of the cornea or sclera substantially centrally thereof by precisely guid ingjthe curved needle lit-between the spaced tines 4 and 5. Thus, the needle 18 does not pierce the inside surface of the cornea or sclera 16 and is otherwise prevented from piercing the surface of the cornea or sclera by the protection and obstruction offered by the pallet or blade 11. The other lip 17 of the corneal or scleral incision is similarly treated; thisv is known as a doublearmed suture. However, a single-armed suture can be used with: the forceps of my invention. In this case the full curved needle is started in the surface of the cornea or sclera" and emerges in the coaptation margin just above the: elevationin the pane blade. If the point of the needle should go too deep in the thickness of the cornea or sclera the point strikes the ridge 14- and must be withdraw sufficiently to'permit it to emerge above theridge. From this it will be seenthat it is almost impossible to put the needle in too deep'if reasonable care is observed, though not altogether as sure and easy as when the doll.- ble-armed suture is used. In Fig. 4 I'have shown the operation where needle 19 is introduced through the co.- aptation'margin of the right hand portion of the corneal or scleral lip 17. In both the operation arrangements of Figs. 3 and 4 the curved needles18 and 19 connect withv thread 20; enabling the thread to be drawn through the lips of the cornea or sclera.
In Fig. I have shown the manner in which the suture is tied at 21 for binding the coaptation marginal edges 16- and 17 together for healing. Fig. 12' shows the view which is generally seen by the surgeon where the lip of the cornea or scleraincision covers the pallet or blade 11 to the offset of shoulder 12. The surgeon visually measures the amount of overlap of the lip of the cornea above the pallet or blade 11 by the position of the notches or markers 9 and on the tines 4 and 5.
The pallet or blade 11 provides adequate protection against" penetration of the needle into the cornea or sclera. The tines 4' and 5 are so spaced that they center and guide the needle through the lip of the cornea or sclera in properly centered position without harmful pp e.
While I have described my invention in certain preferred embodiments I realize that modifications may be made and I desire that it be understood that no limitations upon my invention are intended other than may be imposed by the scope of the appended claims.
