METHOD AND APPARATUS FOR ANASTOMOSING AND INCISING BRIEF OF THE INVENTION 1. Field of the Invention This invention relates to the field of surgical instruments used for open or closed methods of anastomosis. In particular this invention relates to a method and apparatus used to perform incisions and suturing through viscera positioned in side by side relation. More particularly this invention relates to the field of gastrointestinal surgery to connect bowel sections or bowel sections to a stomach forming a single chamber therebetween.

2. Prior Art Surgical instruments to perform anastomosis are known in the art. Prior arthas provided instruments where viscera may be clamped-and restrained by insertion of a longitudinal pin through folds in an undulating viscera path. However, prior art has not provided an instrument which will allow both incision of the viscera combined with a direct suturing. In addition, prior art has utilized a device having a handle to positionally restrain the device and clamped viscera during the operation which due to body cavity dimensions provides a restriction on the type of operation and ease of insertion of the device. Further, prior art in this field has not shown an instrument to be easily adaptable to both open and closed methods of anastomosis since a closed method necessitates the device to be clamped external to the viscera being incised. Prior instruments in the field also do not provide the surgeon with the option of providing a double orsingle layer suturing of the side by side viscera on vertically opposing sides of the incision.

SUMMARY A method and apparatus for incision guidance through viscera and anastomosing which comprises a first and second pair of opposing elongated longitudinal members. The longitudinally extending members of both the first pair and second pair are horizontally opposed and have mutually engageable coacting undulating surfaces with the second pair of members being disposed in vertically displaced contact and longitudinally aligned with the first pair of members. An incision guide path is provided between the vertically disposed contacting first and second paired members with each of the pairs of members having a continuous longitudinal passage therethrough repeatedly intersecting the engageable surfaces. Vertical alignment and clamping means align and maintain the first and second paired members in a predetermined opposed engageable relationship.

An object of this invention is to provide an improved method and surgical instrument in the performance of open or closed anastomosis.

It is another object of this invention to provide an instrument which will allow combined incision and suturing of viscera in a minimum of time and steps.

It is a further object of this invention to provide an instrument which is optimally configured to the various body cavities within which the surgeon must operate.

It is still another object of this invention to provide a surgical instrument which may adjustably clamp the viscera in a fixed position without causing damage to sensitive tissue areas.

tooth DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of the anastomosis apparatus;

FIG. 2 is an elevational view of the anastomosis apparatus in a clamped position;

FIG. 3 is a cross-sectional view of the anastomosis apparatus restraining side by side viscera taken along the section line 3--3 of FIG. 1; and,

FIG. 4 is a partial plan view of the apparatus showing the horizontally opposing teeth in a clamped position and suturing guide path.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1, 2, and 3 there is shown a selfdouble suturing apparatus or assembly 5 to provide for incision and anastomosing guidance as well as placement restraint between

viscera

45 and 46 positioned in side by side relation. In general, assembly 5 is suitable to provide an incision and anastomosing guidance path for the connection of pliable membrane tubes such as between sections of the bowel or duodenum to stomach sections to form a singular cavity therebetween.

Suturing apparatus 5 comprises a first and second pair of longitudinally extended

members

10 and 30 including

elongated members

11, 12, 31 and 32. In construction, paired

members

10 and 30 are formed of stainless steel or other such metal substantially inert to chemical reactions with internal bodily organs. Assembled, members 11 and 12 are horizontally engageable and coacting throughout the longitudinal extension of pair members 10. In

similar fashion members

31 and 32 of second pair 30 coact with each other in a horizontal direction and contact respective members 11 and 12 in a predetermined vertical contact displacement to form the generally rectangular and longitudinally extended apparatus 5. Members 11, 12 as well as

members

31, 32 interface and are engageable with each other along the common boundary of

viscera

45 and 46 with

members

31 and 32 contacting elongated members 11 and 12 respectively in the longitudinal direction and substantially horizontal plane.

Longitudinally extended

members

11, 12, 31 and 32 of first and second paired

members

10 and 30 have respectively formed thereon a plurality of mutually opposed horizontally extending

teeth

15, 20, 35 and 33. Teeth 15, 20, 35 and 33 are substantially directed normal to the longitudinal extension of paired

members

10 and 30 and are displaced longitudinally with respect to each other in order to permit a continuous interface between crest l3 and root 14 between two consecutive teeth on an opposing extended member to provide a coacting undulating interface between paired

members

10 and 30 when

respective members

11, 12 and 31, 32 are engaged.

The total tooth depth between crest 13 and root 14 of

teeth

15, 20, 35 and 33 is constant throughout the extension of paired

members

10 and 30 to provide constant pressure on

viscera

45 and 46 along the contacting length thereby eliminating possible stress concentration points. In addition, crests 13 and roots 14 are rounded having an arcuate contour of sufficient dimensions to provide a restraint to viscera 45 and 46 without crushing or causing a puncture in an area where crests 13 engage roots 14 on opposing surfaces of

viscera

45 and 46. In practice, a wide variety of tooth sizes have been found to be operative, however, in normal practice the ratioof radius of curvature of crest 13 to total tooth depth usually ranges between k and 1. Body cavity openings in gastrointestinal operations of the kind herein described define an optimum'overall longitudinal length of apparatus in the range between 4 and 5 inches and a vertical dimension of between 1 and 2 inches when paired

members

10, 30 are in an engageable position.

Suturing guidance paths are provided by a pair of longitudinally directed slots or grooves 24 and formed in each of the plurality of

teeth

15, 20, 35 and 33 of

respective members

11, 12, 31 and 32.

Slots

24 and 25 are rectangularly formed in a horizontal direction within the respective tooth and slightly in excess of the mid-point depth between crests 13 and roots 14 to form a longitudinal through path substantially rectangular in nature displayed by

end slots

27, 26 of FIG. 1. As shown in FIG. 3 when paired members 10 and are engaged in

operation grooves

24 and 25 overlap with similar slots formed in a horizontally opposing elongated member to form double rectangular through

passages

41 and 42 on first pair members 10 and similar through passages 43 and 44 within second pair members 30.

When longitudinally extended members 11, 12 and Clamping apparatus to horizontally position

respective members

11, 12 and 31, 32 are provided on respective

first ends

29, 28 and 37, 38 as well as

second ends

16, 19 and 36, 34. Pivoting hook or bale 17 is rotatably 31, 32 are horizontally engaged,

viscera

45 and 45 are forced into an undulating path at the interface between paired

members

10 and 30. As is shown in FIG. 4 the undulating path forms folds in

viscera

45 and 45 substantially following the contour of

teeth

15, 20, and 33 through which a suture may be passed within

passages

41, 42, 43 and 44 throughout the longitudinally extended paired

members

10 and 30 to

anastomose viscera

45 and 46.

Incision guide path shown in FIG. 2 passes horizontally through apparatus 5 to permit incision of viscera and 46 therein forming a common chamber or cavity. Relief surface provides a longitudinal recess between

first end

28 and 29 and

second end

16 and 19 on the lower surface of respective members 11 and 12. In a similar manner relief surface 50 provides a longitudinal recess between

first ends

38 and 37 and

second ends

36 and 34 of

respective members

31 and 32 to form at the vertical contact interface between paired

members

10 and 30 longitudinal guide path 40 extending in a horizontal direction through apparatus 5. A scalpel or other knife may now be inserted into guide path 40 to longitudinally cut through viscera 4S and 46 when paired

members

10 and 30 are engageably positioned.

Vertical alignment of paired

members

10 and 30 in an operating condition within respective chambers formed by

viscera

45 and 46 is accomplished by extension element 21 formed on second end 19 of longitudinally extended member 12. Extension element 21 is directed substantially perpendicular to the horizontal plane and extends in an outward direction from the lower surface of second end 19. Opening 51 formed within second end 34 of member 32 is substantially the same diameter as element 21 to permit slideable insertion of element 21 within and through opening 51. In this manner, contacting surfaces between

extended members

12 and 32 may be brought into vertical alignment in fixed position on one side of viscera 46.

attached to recesses in the upper and lower surfaces of second ends 16 and 36. Bale 17 is formed as a U-section having end hooks to engage upper and lower surface recesses and is inserted within recesses 18 formed on an end surface of second ends 19 and 34. Engagement of hook 17 within recess 18 therein provides one point of horizontal restraint between

members

11, 12 and 31 32.

Adjustable clamps 22 are rotatably secured to opposing first ends 29 and 38 on elongated members 11 and 32. Rotation about ends 29 and 38 to an opposed position contacting first ends 28 and 37 is provided by pin attachments through clamps 22 into upper and lower surfaces of first ends 29 and 38. Threaded thumb screws 23 passing through the U-shaped frame of clamps 22 may be brought into contact with

respective members

12 and 31 when clamps 22 are in an opposed position. Continual turning of threaded screw 23 permits more force to be applied to the opposing elongated member causing a greater interface engageable pressure to be exerted between

members

11, 12 and 31, 32. Adjustment of the force is necessitated by the fact that

viscera

45 and 46 must be restrained between paired

members

10 and 30 with sufficient pressure to positionally fix but less than that force which would crush or cause any tissue damage.

In the manner described, apparatus 5 may be inserted within side by

side viscera

45 and 46 within respective chambers in fixed relation thereto to provide a guidance path 40 for incision and a set of continuous through

passages

41, 42, 43 and 44 through which sutures may be inserted to secure

viscera

45 and 46 above and below the incision. I

In operation, apparatus 5 has led to a new method for incision and anastomosing of

viscera

45 and 46. The first step of the method provides for forming an undulating path for

viscera

45, 46 in a substantially longitudinal direction between opposing

longitudinal members

11, 12 and 31, 32 of paired

members

10 and 30 by inserting

elongated members

11, 12, 31 and 32 on opposing surfaces of

viscera

45 and 46.

Respective members

11, 12 and 31, 32 are interfaced by positioning the respective members in a vertical alignment through insertion of element 21 into opening 51 of elongated member 32, and then further positioned in a longitudinal direction by engaging tooth crests 13 with opposing tooth roots 14 on opposing sides of

viscera

45 and 46. Opposing

members

11, 12 and 31, 32 are clamped in a horizontal restraint by inserting pivoted hook 17 into opposing member recesses 18 on second ends 19 and 34. First ends 29, 28 and 37, 38 are horizontally restrained by actuation of adjustable clamps 22 about an opposing longitudinally extended member. I

The surgeon then cuts the

viscera

45 and 46 through path 40 provided between the vertically displaced contacting

members

11, 31 and 12, 32. Separate sutures are passed longitudinally through each of

passages

41, 42, 43 and 44 by means of needles to provide a connection between cavities of

viscera

45 and 46 with a double line of sutures on each side of the incision. Adjustable clamps 22 and pivoting hooks 17 are released from the holding action and

members

11, 12, 31 and 32 are removed.
