May 19, 1953 E'. D. SUGARBAKER SURGICAL CLAMP Filed July 30, 1951 INVENTOR EV-ERETT D. SUGARBAKER,

BY f... VLM ATTORNEYSl Patented May 19,ry 1953 OFFICE SURGICAL CLAMP Everett D; Sugarbaker,` Jetterson City, Mo.' Application July 30, 1951,.seria1No. $9,245

.12 claims. (01.128-334)` This invention relates to surgical clamps and particularly to an improved recto-colic anastomosis clamp. i

It is highly desirable to carry out bowel anl.. astomoses by clamping together inturned portions of the bowel ends and maintaining the ends -so clamped until agglutination occurs. at 4the periphery of the-junction. This method, however, involves several diiculties. It is necessary that the bowel ends remain clamped for periods on the order of 7-10. days, and such periods are so long that obstruction of the bowel by the clamping means would be .highly dangerous because of the accumulation of infective material inthe bowel above the clamp. Also, application of the clamp, and manipulation of the clamp after it is applied,.have heretofore been exceedingly diicult. y

The present inventionprovides a rectocolic anastomosis clamp whereby the foregoing dif` I culties are overcome. In Aaccordance with the invention, the clamp is so constructed as to allow ready escape of the mucoid contents of the bowel when the clamp is.v in place. .The

dangerous accumulation of infective material is thus prevented, and the bowel may be irrigated if necessary. 4 y y The anastomosis clamp of the invention is also characterized by a combination of structural A features which make application and adjustment of the clamp far less diicult than has ybeen the case heretofore. The clampis adapted to be assembled within the bowel, with the parts of the clamp being inserted through the..anus,

the structure being such that positioning of: the severed ends of the bowelon the faces ofthe clamp is readily `and positively accomplished. According to the invention, clamping pressure is establishedand adjusted by manipulation ci assembled and in place to accomplish an anas-= tomosis of the lowery colon, the clamp being `shown in longitudinal section;

Fig. 2 is a side elevation offtheclamp, with the clamping members separated, partly in longitudinal section; u. Fig. 3 is an end view of the lower clamping j The lower clamping shank 4 having at one end an enlarged, poraber .2. -ben2 adjacent the clamping faceIZ is a pin I5 and, .toreceivejthe pin l5, the tubular ele- .ment Illfof themember I is provided withone or more longitudinal slots Iopen at' the end member-showing the clamping face thereof; andV Fig. liv-is an'en'd- View of the upperclamping member.

Referring now to the drawings in detail, it

member 2, and Va central tube 3 adapted to coact with I and 2. v

member I includes a tion 5 with a transverse shoulder t` andatthe 'other end a vbody 'I withan annular clamping iace, Fig. 3.` The clamping. member I .is ,t u, bular, being provided With an axial bore` 9 extending entirely throug-h the member. Arranged coaxially with the bore 9 is a tubular extension I0 directed-.away fromthe clamping face 3.-y Thus, the lclamping. member I' comprises .a generally tubular memberwith thebody .lconstituting an intermediate outer enlargement.

The upper clamping member 2 comprises a.

Vbody II havingan annular lclamping face I2 -and'an vaxial bore I3. A portionpf. the bore I.3 is interiorly. threaded at I4, and the bore .adjacent theclamping face I2 has a diameter such that .the tubular element I0 ofthe lower clamping. member I -may slide into and .t snugly within thebore of the .clamping mem- Extending into the bore I3 of the inemf portion capable .of being inserted through the bores 9 and.v I3 andhaving at one end an enlarged por-tion Il presenting a transverse shoulder `...IILand .at the Aother end an exteriorly threaded portion i9.

. As seenin Fig.,.1, when the clamp is assembled.. the clamping member I is carried on the tube l3, `being secured against. axial movement in one direction lby contact Ybetween the'shoulv-ders .iiA and'I. The interior threads I4 ofthe clamping member 2 engage the exterior threads I9 of .the tube 3,.,so that relative rotary motionbetween -the tube 3 and the member 2 will cause the latter .to be adjusted either toward ing upon the direction of rotation. It will be noted that,- when the pin I5 is engaged in vone of the slotsdi the clamping members I-and 2 may not rotate relative to each other. When ably positioned'uponsaidrtube with said 'shoulder facing saidstopjmember;l `a second clanlping` member comprising ;a 'body; portion having an" annular clamping face and an interiorlythread'ed axial bore, said second clamping 4merriber' being positioned onl said tube with its vinterinr threads engaging theexterior threads of said tubeI andv with its4 clamping face directed toward' that oi said first clamping rmernb'eriwhereby relative rotation between said tube and said second clamping member in one direction forces said clamping faces together;v -andmeans-for securing a severed bowel ed over each of said clamping faces when said faces are spaced apart.

4. In a recto-colic anastomosis clamp, the combination of a pair of opposed clamping members each having an .annular clamping faceand an axial bore, one of ,said vclamping `members having an extended shank terminating' in a transverse shoulder opposite the clamping face thereof, the bore of the other of said clamping members being interiorly threaded, and a central tube'extending through the bore of said one clamping member and terminating at one end in an exteriorly threaded portion engaging the interior threads of the bore of said other clamping member, said tube being provided at its other end with an exteriorly positioned stop member facing the transverse shoulder of said one clamping member, and said shank being of such length as to extend through the rectum of a patient when saidclamp is in place within the colon.

5. In an anastomosis clamp, the combination of a central tube having at one end an exteriorly enlarged portion providing a transverse shoulder facing the opposite end of the tube, and a pair of opposed clamping members each having an annular clamping face and an axial bore, said tube being positioned within the bores of said clamping members, one of said clamping members .being provided with a transverse shoulder opposite its clamping face and facing the shoulder of said tube, and said tube and the other of said clamping members having interengaging screw threads.

6. In an anastomosis clamp, the combination of a tube having an exteriorly threaded end portion and an exterior shoulder spaced axially from said end portion; a clamping member having a shank, a body portion with an annular clamping face and an axial bore extending through said shank and body portion, said clamping member being slidably mounted on said tube with the shank thereof extending toward said shoulder and said clamping face exposed toward the threaded end of said tube; and a second clamping member having an annular clamping face and a threaded axial bore, said second clamping member being threaded upon said end portion of said tube with its clamping face opposed to that of said first mentioned clamping member.
