Definitions

  • the invention is for a device for clamping organic tissue, in particular blood vessels in accordance with the general term in patent claim 1 , applicable in particular for minimal invasive surgery.
  • the invention is based on the task of creating a device such as described at the beginning which allows the precise holding and clamping of organic tissue, a variable equipping of the clamp bars in a simple manner, the design of the tissue clamp with little expense and can be used and produced inexpensively.
  • this and the clamp bar to be pushed must have at least one guiding device.
  • the device i.e. its applicator base in the simplest manner possible with the two clamp bars and to make the tissue clamp by merging the two clamp bars.
  • a holding device is attached to the clamp bars which aids in a precise approach of the clamp bars and allows their merging to a tissue clamp.
  • the pushing in and holding of the clamp bars is also or exclusively form-fitting.
  • the holders and clamp bars are provided with holders and guides so that an exact positioning of the clamp bars in the holders is guaranteed.
  • the holders and guides are formed by at least one transverse slot within and perpendicular to the applicator base and at least one corresponding projection from the base belonging to the clamp bar. It may, however, also be that the projection of the holder of the applicator base and the traverse slot is attached to the base of the clamp bar.
  • the position of the distal clamp bar to the applicator base can be secured in that the traverse slot of the distal holder is in the insertion direction of the first distal clamp bar and the projection of the clamp bar slips into the traverse slot force and form-fitting; the projection is shaped as a corresponding projecting shoulder from the base of the first clamp bar.
  • the positioning of the clamp bar to the applicator base can also be benefit from the traverse slot and the attachment shoulder being placed on both sides of the first holder or base on the side facing the base.
  • the positioning and moving can additionally be supported in that the one traverse slot is located on each side of the second holder, where the corresponding guide pins on the base of the clamp bar can enter.
  • the traverse slots and the guide pins are to be dimensioned so that they fit together with almost no play and the vertical position of the clamp bar to the applicator base as well as the parallelity to one another is always guaranteed.
  • the cross-section of the traverse slots and guide pins must correspond to one another.
  • the cross-section of the guide pins is preferably round or rectangular and those of the traverse slot u-shaped.
  • the exact moving of the clamp bars toward one another along the applicator base is made possible in a simple manner in that the guideway in the applicator base connecting the first and the second holder and the subsequent corresponding clamp bar is assigned a guideway direction.
  • This is formed by at least a longitudinal slot and at least a corresponding projection or guide pi, which is either assigned to the applicator base or the clamp bar or its base.
  • the exact positioning and the moving of the clamp bar can also be improved by putting several longitudinal slots parallel to one another and across from one another within the guide slot intruding into the correspondingly located projections or guide pins of the clamp bar.
  • the cross-section of the guide slot of the applicator base can then also have a T or double-T shape.
  • the holders, clamp bars and the guide slot are to be dimensioned so that the tissue clamps from the individual clamp bars are pushed out of the guide slot in the longitudinal direction and separated from the applicator base.
  • the width of the distal holder must therefore be at least equal to or larger than the width of the proximal holder.
  • the attachment device is formed by a holding pin on the one clamp bar and a coaxial holder bore on the other clamp bar, whereby this runs lengthwise along the applicator base so that the attachment device is formed simply.
  • the bases of the clamp bars are on the holding pins or the holding bore and this is formed with the corresponding traverse slot so that the attachment device can hardly come into contact with the tissue to be clamped.
  • the holding pin and the holding bore have an overlapping which guarantees on the one side a sufficient parallelity of the clamp bars while clamping the tissue and on the other side allows for the certain force and/or form-fitting attachment in the final position. As a result a high degree of functionality is achieved with simple means.
  • clamp bars are not parallel, but slightly conical to one another so that when merging the clamp bars to the tissue clamp firstly the end away from the applicator base comes to the opposite enclosure and by proper deformation during the further merger of the clamp bars, these come to the opposite enclosure over a greater distance.
  • the clamp bars are to some extent tensed against one another which can have a reducing effect on the clamping force on the tissue as a result of the dimensioning.
  • the cross-section of the holding pin and the corresponding holder bore have a shape geometric figures grouped around a central point or going into one another, whereby the interacting surfaces enlarges both and a form-fit closure is allowed in addition to the force-fit closure.
  • a secure position of the clamp bars to one another can be significantly improved as a result.
  • FIG. 1 front view of device in partial and partial cross-section presentation
  • FIG. 2 top view of an applicator base as per FIG. 1 , in partial presentation,
  • FIG. 3 front view of a distal clamp bar as per FIG. 1 ,
  • FIG. 4 side view of the clamp bar as per FIG. 3 ,
  • FIG. 7 front view of another execution of the device, in partial and parital cross-section presentation,
  • FIG. 8 top view of an applicator base as per FIG. 7 , in partial presentation,

  • FIG. 11 top view of the clamp bar as per FIG. 11 ,
  • FIG. 12 cross-section A-A as per FIG. 2 ,
  • the device 1 for clamping organic tissue, in particular blood vessels has an applicator base 2 , which stretches distally along a proximal base which is not described in greater detail. With the base the applicator base 2 is also connected to an application instrument which is not described in further detail. Within the applicator base 2 an inner pusher 3 can be pushed essentially along the entire length of the guide slot 4 of the applicator base 2 by means of the application instrument, whereby the guide slot 4 stretches on the opposite side of the application instrument from its distal end 5 up to its proximal end.
  • the ends 5 and 6 each have clamp bars 7 , 8 , between which their clamp bases 9 can clamp off the blood vessel.
  • clamp bars 7 , 8 reach from bases 10 , 11 in such a manner that the clamp bases 9 are always vertical to the applicator base 2 and parallel to one another. It is, however, also possible that the clamp bars 7 , 8 and their clamp bases 9 are slightly conical to one another and to some extent are pre-stressed is such a manner that when merging the clamp bars 7 , 8 first their areas away from the applicator base 2 come to the opposite piece and only after wards do the other clamp bases 9 approach one another.
  • the distal end 5 of the guide slot 4 is on a holder 12 ( FIG. 2 ) in which the base 10 of the first distal clamp bar 7 can be inserted vertically to the applicator base 2 .
  • a second proximal holder 13 is on the proximal end 6 of the guide slot 4 ; the second proximal clamp bar 8 can be inserted vertically to this.
  • the holders 12 , 13 differ from the other guide slot 4 in that the clamp bars clamp bars 7 , 8 can also be attached in them, while only guide slot 4 serves as the guide of the proximal clamp bar 8 to the distal clamp bar 7 .
  • the holders 12 , 13 and the bases 10 , 11 have holders and/or guides which guarantee the secure and exact positioning on the one side during the loading of the applicator base 2 and on the other side during the reciprocal moving of the clamp bars 7 , 8 alone or in addition to the form fit.
  • the holders and guides are, on the one side, formed from at least one traverse slot 14 ( FIG. 2 ) of the holder 12 , 13 .
  • at least one corresponding projection to traverse slot 14 is planned which is shaped as a guide pin 15 and on the clamp bars 7 , 8 .
  • the guide pins 15 and traverse slots 14 are correspondingly shaped in such a way that the guide pins 15 are inserted into traverse slot 14 with almost no play and are held so that the essentially vertical position of the clamp bars 7 , 8 to the applicator base 2 is always assured.
  • the holders and guides of a distal holder 17 of an applicator base 23 and a base 18 of a clamp bar 18 on the one side are formed by a traverse slot 20 and on the other by a projection made of the projecting attachment shoulder 21 (FIGS. 9 , 10 , 11 ).
  • a proximal clamp bar 25 of device 16 differs from the one described above in that on each side of a base 26 a total of four guide pins 15 ( FIG. 7 ) stand out which in pairs slip into two parallel traverse slots 14 of a holder 27 .
  • the holders 12 , 13 and 17 , 27 are connected with one another by means of the guide slot 4 and 24 so that the proximal clamp bars 8 or 25 are pushed along the guide slot 4 or 24 to the distal clamp bars 7 or 19 and the two can be connected to clamp off a blood vessel and to form the tissue clamp.
  • the guide slots 4 , 24 and the bases 11 or 26 of the clamp bar 8 or 25 have at least one guide device which serves to precisely position the clamp bars 8 , 25 while it is being pushed along the applicator base 2 , 23 .
  • the guide device is formed on the one side by at least one longitudinal slot 28 , which stretches along the guide slot 4 , 24 and on the other side by at least on of the guide pins 15 rising up out of the base 11 , 26 .
  • every side wall of the guide slot 4 , 24 there may be one, two or more parallel longitudinal slots 28 so that the cross-section of the guide slot 4 , 24 may be, for example, T or double-T shaped.
  • the positioning of the clamp bars 8 , 25 can be improved in that two pairs of guide pins 15 rise next to and on top of each side of the bases 11 , 26 and slip as pairs into the specific longitudinal slot 28 .
  • the guide device may also be formed by at least one longitudinal slot 29 in a base 30 of a clamp bar 31 and at least on projecting base 32 which stretches along a guide slot 33 above the same in the guide slot 33 .
  • an applicator base 34 is not for-shaped, but rather is preferably equipped with a base plate.
  • the base 29 can be leaned against this when equipping the applicator base 34 and inserting at least on proximal clamp bar 31 and positioned in such a way that the base 32 can slip securely into longitudinal slot 29 when being moving the clamp bar 31 along the guide slot 33 .
  • both the longitudinal slot 29 and the base 32 on the other side will be paired ( FIG. 13 ).
  • the guide slot 33 is used for equipping the applicator base 34 with the proximal clamp bar 31 and the incorporation such as the proximal holders 13 can be avoided.
  • the upper portions of the applicator base 34 can be bent away from each other when inserting the clamp bar 31 that first the base 29 goes between the bases and at the end of the equipping of the base 32 jumps in the longitudinal slots 29 and then the clamp bar 31 can be pushed within the guide slot 33 .
  • the base 32 which may also be shaped as one or more guide pins 15 in the longitudinal direction of the applicator base 34 , on the clamp bar 31 and the guide slot 33 to the applicator base 34 .
  • clamp bars 7 , 8 , 19 , 25 , 31 are shaped in various ways and they can be assigned to various corresponding holders and guides, they have in common that each pair of clamp bars 7 , 8 , 19 , 25 , 31 have an attaching device which essentially consists of a holding pin 36 and a correspondingly shaped and coaxially placed holding bore 37 this attachment device serves on the one hand to position the corresponding two clamp bars 7 , 8 , 19 , 25 in the final phase of their approach to one another and, on the other hand, to achieve their permanent connection to their final position to the tissue clamp.
  • the holding pin 36 and the holding bore 37 are located on bases 10 , 11 , 18 , 26 , 30 so that they are outside of the actual clamping area and hardly come into contact with the tissue to be clamped off.
  • the axial extension of these and the resultant length of the overlapping which also depends on the thickness of the tissue to be clamed off is to be dimensioned so that a precise positioning and permanent connection results.
  • Both show corresponding cross-sections which allow for force- and form-fitting interaction. This is achieved in that their cross-section is formed by geometric figures placed around their joint axis in a star-shape, for instance, three overlapping circles. Any other cross-section is, however, also conceivable as long as it allows the force- and/or form-fitting.
  • the cross-sections of the holding pin 36 and the holding bore 37 may, correspondingly, be shaped like pyramids, cones or ellipses.
  • the clamping off of the tissue by means of device 1 , 16 occurs as follows.
  • the applicator base 2 , 23 is equipped with the clamp bars 7 , 8 , 19 , 25 in that firstly the distal clamp bars 8 , 25 are inserted vertically in the distal holder 12 , 17 and then the proximal clamp bars 8 , 25 are inserted in the proximal holders 13 , 27 . In this way the guide pin 15 or the attachment shoulder 21 slid into the traverse slots 14 or 20 .
  • the guide pins 15 on the distal side of the distal holder 12 , 17 are sheared off from the bases 10 , 11 , 18 , 26 or the attachment shoulder 21 comes out of the traverse slot 20 as soon as the force exerted by the inner push exceeds the value required for merging the clamp bars 7 , 8 , 19 , 25 . the applicator base 2 , 23 can then be removed from the operation area and pulled out of the trocar.
  • the shearing off of the projecting pins 15 occurs because the longitudinal slots 28 mouth in the distal holder 13 , 18 and do not continue up to the distal front side of the applicator base 2 , 23 .
  • the attachment of the distal clamp bar 7 is significantly supported by the projecting pins 15 .
  • the shearing off happens only after the tissue is clamped off and the force required by the inner push for the remaining merger of the clamp bars 7 , 8 is exceeded.
  • the shearing of the guide pins 15 described may, however, also be avoided or excluded if the longitudinal slot 28 or longitudinal slots 28 of the guide slot 4 extend beyond the distal holder 12 up to the distal end 5 of the applicator base 2 and the guide pins can exit from the applicator base 2 in these.
  • the shearing off of the guide pins may also be excluded in that the distance of the distal holder 12 and the subsequent guide slot 4 is so large that the proximal clamp bar 8 can also fit through along with the projecting guide pins 15 .
  • the longitudinal slots 28 can be continued up to the distal front of the applicator base 24 and therefore exclude a shearing of the guide pins of the proximal clamp bar 25 , the secure attachment of the distal clamp bar 19 is here, however, primarily as a result of the attachment shoulder 21 and the corresponding traverse slot 20 .
