July 29, 1941. J. SQRUBIN TISSUE HOLDER Filed April 1, 1940 1/055 544 [/1/ Raw/v INVENTOR ATTORNE Patented July 29, 1941 one area

My invention relates to tissue holders and has particular reference to devices for grasping and holding body tissues during surgical operations.

In the performance of many surgical operations it is necessary to dissect certain tissues or organs which must be held in the operative field without possibility of such tissues or organs becoming obscured from ready access and also it is frequently necessary to localize portions of the tissue or bodies within the tissues or organs so as to prevent inadvertent dislocation of the bodies until their removal by performance of further steps in the operation can be accomplished.

One particular instance in which such segregation of the tissues and localizing of bodies therein is of great importance is in the performance of ureteral lithotomy. In the performance of this type of operation, the ureter, or at least that portion thereof in which the calculus is located, must be dissected and held in a suitable position to permit the subsequent opening of the ureter for. the removal of the calculus therefrom. The ureter is, like most body tissues, difficult to handle and to fix in a given position by reason of the slippery nature of the organ. Further difiiculty in the performance of such operations-is that handling of the dissected ureter in attempts to tie the same with tapes or other known holding devices frequently dislodges the calculus from its then position, usually causing the, calculus to move back toward the kidney and rendering the operation for removal thereof more complicated and more difficult.

Moreover, the employment of known surgical clamps and clamping devices for thepurpose of grasping and holding many body tissues, such as the ureter, is unsatisfactory due ,to thefact that the forces required to securely engage such clamps with the tissues or organs requires the squeezing or compressing of the tissues so that injury to the tissues results therefrom. 1

It is therefore an object ofmy invention to provide a tissue holder which will securely engage and retain satisfactory tractile grip upon tissues without exerting crushing or injurious compressive forces upon the tissues or organs.

Another object of my invention is to provide a tissue holder of the character set forth in which the tissue or organ is grasped between two similarly shaped ring-like members, the periphery of one being sufficiently large to extend about and completely encircle the other so as to grasp the tissue by a tortuous deflection of the tissue but without squeezing or crushing the tissues therebetween. 7

, Another object of my invention is to provide a tissue holder of the character set forth in which the cooperatingring-like members .may be readily drawn toward each other to rasp the tissues therebetween or moved apart to release the tissues by the manipulation thereof with but one hand of the operator. 7 7

Another object of my invention is to provide a tissue holder of the character setforth in which the ring-like members are self-retaining in any adjusted position.

Other objects and advantages of my invention will be apparent from a study of the following specifications, read in connection with the accompanying drawing, wherein Fig. l is a plan View of. my tissue hol-der illustrating the a relative position of the parts when grasping an ureter and localizing a calculus therein which is to be removed from the ureter; Fig.2 is a perspective View of the clamp shown in Fig. 1 and illustrating the position of the parts when completely separated from each other; and r Fig. 3 is a vertical sectional View taken along line IIIIII of Fig. 1 and illustrating the parts in their assembled positions.

' Referring to the drawing, I have illustrated my holder as comprising an outer ring-like member l and an inner ring-like member 2, the contour of each of these members being of any suitable shape though I prefer that they be con structed of elliptical or oval shape for the purpose of providing long and short axes for the ringlike members to more readily adapt my tissue,

holder'to various types of tissues and body organs. From an inspection. of Fig. 1, it will be observed that the outer ring-like member I is considerablylarger in its dimensions than the inner member 2 so that when themembers are assembled together with the inner member nested within the outer, there is 'a space band 3 of considerable width between these two members.

The outer member is mounted upon or fo-rmed I integrally with a support 4 which preferably extends forwardly and downwardly so as to dispose the outermost end. 5 of the support in parallel relation to the plane .of the ring l but in forwardly offset relation thereto. The inner ring} is similarly mountedup'on or secured to a suitable support 6 which is likewise preferably disposed in a plane parallel to but rearwardly. offset from the plane of thering 2. Formed integrally with or secured 'to the support 4 are a pair of tube-like arms I and B eXtendingfrom the rear face of the support 4 and in a direction transverse to the plane of the ring I. The tubu- I lar arms 1 and 8 preferably engage the support 4 at its lowermost end, that is, as far as it is conveniently practicable away from the center or longitudinal axis of the ring I. The arms I and 8 ar each provided with a longitudinal bore 9 extending therethrough, preferably of rectangular cross section, into which may be received the forwardly projecting rectangular cross sectioned arms I!) and II formed upon or attached to the rear bracket or support 6, the arms l and H extending from the lowermost portion of the bracket 6 and spaced from each other sufiiciently to permit the arms l0 and I l to be readily slidable into the tubular arms 1 and 8, respectively.

By referring particularly to Fig. 3, it willbe observed that the tissue holder may be readily assembled merely by projecting the arms I!) and H into the arms 1 and 8 and then pressing the supports 4 and 6 toward each other, sliding the arms l0 and II within the arms 1 and 8 until the rings have been drawn toward each other a sufficient distance to grasp the tissue or organ to be held. For example, in grasping an ureter the rear ring 2 is placed beneath the ureter and the upper ring is placed above the :ureter when the two rings are in their maximum separated positions but with the arms and II assembled in the tubes 1 and 8.

7 Then by merely pressing the supports 4 and 6 :toward each other, the two rings will approach each other, grasping the ureter indicated at [2 between them in such fashion as to bend the :ureter upwardly as at l3 from behind the front ring I and over the rear ring 2 while at the same time the ureter will be bent upwardly as indicated 7 at 14 by the offset sides of the rings 1 and 2.

It Willbe noted that this method of grasping the ureter does not crush anyof the tissues but retains an entirely satisfactory secure grip upon the ureter merely by the-distorting of the ureter as it passes over and -under-the rings land '2, respectively.

The ureter or other tissue'so grasped may be readily picked up and held in the operative field by one hand of the operator grasping the supports 4 and 6, the rings I and 2 being held in "their gripping relation by reason of the leverage affordedby thedistancebetween the central axes of 'the rings I and 2 and the arms 1,8, l8 and H, any tendency toseparate the rings being opposed 'by=the'twisting'of the arms I0 and II in their respective sockets 1 and-8. Thus the'tissue or -.organ will be retained entirely by'the frictional resistanceof the arms l8 and H and the arms 1 and 8.

While the tissue is so gripped, other subsequent portions of the operation may be performed upon the tissues such as the nicking of the ureter, asindicated at I'5,to open the same and permit the ready removalof the calculus or other body I6 therefrom and 'to permit the re-closing and suturing o fthe organ.

fBy'making the rear holding member land the front holding member I 'both" as rings or-annuli, -theprecise pointoi operation upon'the tissue or organ'maybe left entirely free of any clamping orgripping surfacesandpermit the manipulation 'thereof in the performance of subsequent portions of the operation. For example, in the illustraticn 'shownthe calculus, while held against .pos-

sible escape in either direction along the ureter by the action of my tissue holder, is not in its grasp by any clamp, tie or other holding device and hence the particular point of the operation is entirely free for the performance thereof.

In order to insure against inadvertent slipping of the supports 4 and 6 while holding a tissue, I prefer to roughen at least one of the surfaces of the arms [0 and II as indicated at I! which may be accomplished by producing a satin finish thereto.

When the operation is complete, a clamp may be readily removed by the manipulation of the fingers of one hand as by extending one finger into the space I8 between the front and rear supports 4 and 6 to straighten these supports into substantially parallel relation to each other, whereupon the frictional grip is released and the two'members may be readily separated.

While I have shown and described the preferred-embodiment of my-invention, I do not desire -to be limited to any of the details of construction shown and described herein, except as defined in the appended claims.

I claim:
