Definitions

  • the invention relates to a surgical stapling instrument according to the preamble of claim 1.

  • the fluid ports are needed, for example, in connection with gastric bands that wrap around the stomach for the treatment of pathological obesity in order to reduce the volume of the stomach.
  • the gastric band consists of a loop part with a balloon element that is expandable with a fluid in order to reduce the loop diameter.
  • the fluid is pressed into the balloon element from the fluid port via a hose line, as a result of which the inner cross section of the loop-shaped gastric band is reduced.
  • the fluid port is placed in the vicinity of the abdominal wall in order to supply or remove fluid from the fluid port with the aid of a transdermal injection and accordingly to enable the loop width to be adjusted.
  • the known fluid ports are usually sewn onto the abdominal muscles, the sewing of the fluid ports being very time-consuming.
  • the invention is therefore based on the object of providing a stapling instrument with which fluid ports can be fastened in the body in a simple manner.
  • the invention advantageously provides that the clamp device has a receiving device for a fluid port.
  • the integration of the receiving device for the fluid port in a clamp device has the advantage that the fluid port can be brought into the correct position immediately when the clamp-setting instrument is put on and can be clamped to the body surface in one operation.
  • the clamp device preferably consists of a head part that can be detached from the shaft tube.
  • the head part can be designed as a disposable part for single use, while the remaining parts of the stapling instrument can be reused after sterilization.
  • the receiving device has a holding device for the fluid port.
  • the holding device ensures that the fluid port is held securely while the clamps are being advanced and cannot fall out of the instrument prematurely.
  • a plurality of fastening tabs are integrally formed on the fluid port, the clamps of the clamp device and the fastening tabs being matched to one another.
  • the fastening tabs are therefore intended to receive the clips and enable the fluid port to be clamped directly onto the body surface.
  • the fastening tabs have webs for bending the clip legs of the clips.
  • the webs are spaced so that they are spaced from the bracket legs.
  • the clamp device For each clamp to be set, the clamp device has a clamp slide for axially advancing the clamps in the distal direction, which, by means of two projections, cooperates with the webs of the fastening tabs in order to bend the clamp legs of the clamps.
  • the projections engage on the outside at the level of the staple legs and cause the staple legs to bend in such a way that the ends of the staple legs overlap.
  • the clamp device has a plunger axially movable by the push rod. This stamp does not have to be connected to the push rod, but is pushed axially in the distal direction by the push rod.
  • An ejector for the fluid port is attached to the stamp.
  • the ejector is arranged at an axial distance from the punch.
  • the stamp exerts an axial pressure on an actuating device for the clamp slide, which is exerted by a compression spring when the push rod is displaced distally.
  • the compression spring sits on a rod part arranged between the stamp and the ejector.
  • the actuating device for the clamp slide consists of an annular disk which is mounted axially on the rod part projecting distally from the punch and is prestressed by the compression spring.
  • the washer exerts a uniform pressure exerted by the compression spring on all clamp slides.
  • the annular disc In the pretensioned rest position, the annular disc bears against a stop formed by the ejector.
  • the receiving device for the fluid port receives both the clips for the fastening tabs and the clip slide. Both are inserted in corresponding recesses in the receiving device on its outer circumference.
  • the holding device consists of several holding springs which hook under an annular edge on the outer circumference of the fluid port. This ring edge is preferably formed by a metal sleeve of the fluid port.
  • the head part which can be detached from the shaft tube consists of a screw head and a tube part connected to the screw head. After an application, the head part can be disposed of, while the rest of the instrument can advantageously be reused by sterilization.
  • the screw head is with the shaft tube For example, connected via a screw thread, while the tubular part is in turn connected to the screw head via a screw thread.
  • the receiving device for the fluid port is integrated in the clamp device and arranged at the distal end of the tubular part.
  • the pivotable lever part of the handle is in a stop position in the rest position. This stop position can be released with an unlocking device in order to be able to remove the push rod at the proximal end of the shaft tube.

  • the push rod 28 has at its proximal end a guide element 24, preferably made of plastic, which slides in the bore of the tubular shaft tube 2 and there guides the push rod 28 centrally.
  • the handle 4 receives the shaft tube 2 in a rotatably mounted manner in a tubular section which widens step-wise towards the proximal end, forming a stop for the axial movement of the push rod 28.
