Description

The surgical instrument

The invention relates to a surgical instrument stitching-hook according to the preamble of claim 1.

Such stapling instrument is used to attach a fluid port subcutaneously, for example, on the abdominal muscles.

The fluid ports are used for example in connection of gastric bands which encircle the stomach for treating morbid obesity, to reduce stomach volume. The gastric band is made of a loop member having a balloon member which is stretchable by a fluid in order to reduce the sling diameter. The fluid is pushed through a hose from the fluid port into the balloon member, whereby the inner cross section of the loop-like gastric band reduced. The fluid port is placed in the vicinity of the abdominal wall to supply or by means of a transdermal injection fluid to the fluid port to be taken and, accordingly, to enable adjustment of the loop length.

The known fluid port are typically sutured to the abdominal muscles, the suturing of the fluid ports is very time consuming.

The invention is therefore based on the object to create a stapling instrument, fluid ports can be mounted in the body with easily.

To achieve this object the features of claim 1 are used.

The invention provides in an advantageous manner in that the clamp means comprises a receiving means for a fluid port. The integration of the Aufnahmeein- direction for the fluid port in a clamp device has the advantage that the fluid port can be immediately brought into the correct position with the placement of the stapling instrument and can be clamped in one operation with the body surface.

The clamping means preferably comprises a releasable from the shaft tube header. In this manner, 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 means ensures that the fluid port is held securely during the advancement of the brackets and can not prematurely fall out of the instrument.

a plurality of fastening lugs are integrally formed on the fluid port, wherein the brackets of the bracket means and the fastening lugs are adapted to each other. The fastening tabs are therefore intended to receive the clips and permit the stapling direct the fluid ports on the body surface.

The mounting plates have ridges on for bending the staple legs of the staples. The ribs are spaced so that they are spaced apart from the staple legs.

The clamping means comprises, for each bracket to be set to a staple pusher for axially advancing the staples in the distal direction, which cooperates with the aid of two projections of the webs of the fastener tabs to bend the staple legs of the staples. The projections engage the outside at the level of the staple legs and cause a bending of the staple legs in such a way that the ends of the staple legs overlap.

The clamping device has an axially movable push rod of the punch. This stamp need not be connected to the push rod, but is pushed forward by the push rod axially in the distal direction.

To the stamp an ejector port for the fluid is mounted. In this case, the ejector is disposed at an axial distance from the punch. The punch exerts on an actuating device for the staple pusher of an axial pressure exerted on the distal movement of the push rod via a pressure spring.

The pressure spring sits on a disposed between the punch and the ejector rod part.

The actuating device for the staple pusher consists of an annular disc, which is axially supported on the distal projecting from the plunger rod portion and is biased by the compression spring. The washer exerts on all staple pusher from a pressure exerted by the compression spring pressure uniform.

The annular disc is located in the biased rest position against a stop formed by the pusher.

The receiving device for the fluid port accommodates both the brackets for the fastening straps and the staple pusher. Both are inserted into corresponding recesses of the receiving device on the outer periphery thereof.

The holding means consists of several retaining springs, which hook with a ring edge on the outer periphery of the fluid port. This annular edge is preferably formed by a metal sleeve of the fluid ports.

The releasable from the shank head pipe part consists of a screw head and a screw head connected to the pipe part. After an application of the head part can be disposed of, while the rest of the instrument is reusable by sterilization in an advantageous manner. The screw head is connected to the shank tube, for example, via a screw thread, while the tube part is in turn connected to the screw head of a screw thread.

The receiving device for the fluid port is integrated in the clamp means and arranged at the distal end of the tubular member.

In a preferred exemplary embodiment, the pivotable lever portion of the handle is at rest in a stop position. This abutting position can be released with an unlocking device in order to remove the push rod at the proximal end of the shaft tube.

In the following, an embodiment of the invention will be explained in more detail with reference to the drawings.

The stapling instrument 1 comprises a tubular shank 2, which is rotatably mounted in a handle 4 and is rotatable by means of a twist grip 16 about the longitudinal axis of the shaft tube. 2 The handle 4 consists of a pivotable lever member 6 and a rigid gripping member 8, wherein said pivotable lever part acts 6 with the upper lever arm 7 on a head portion 26 at the distal end of a push rod 28th The push rod 28 has at its proximal end a guiding member 24, preferably made of plastic, on which slides in the bore of the tubular stem tube 2, where the push rod 28 centrally performs.

The handle 4 takes the shaft tube 2 mounted rotatably in a tubular section extending out stepwise toward the proximal end, extends a stop for the axial movement of the push rod 28 forming. In the enlarged cross-section the guide element is axially guided with a hemispherical rounded portion 26 Kop 24th Between the head portion 26 and the proximal end of the shaft tube 2, a compression spring 32 is arranged coaxially on the guide element 24, which is supported on the one hand on the head part 26 and the other hand on the end face of the proximal end of the shaft tube 2 in the handle. 4 The compression spring 32 causes the return of the push rod 28 when the pivotable lever portion 6 of the handle is pivoted back into its rest stop or 4 position.

At the distal end of the push rod 28 further distal guide member 20 is disposed. A rotating handle 16 is used to rotate the shaft tube 2 having a head portion 12 about the longitudinal axis of the shaft tube. The base body 2 is secured in the handle 4 with an axial stud 46 which engages in an annular groove 48 on the outer periphery of the shaft Röhres 2 at its proximal end.

The handle 4 has, at the grip part 8, a stop means 9 which forms a stop surface 11 for the upper lever arm 7 of the lever member. 6 The upper lever arm 7 is in the rest position of the lever part 6 against the stop surface. 11 With the help of a push button 22, the resilient stop means 9 can be moved laterally so that the upper lever arm 7 with the lever member 6 to be further rotated in the clockwise direction to the push rod with its Führungselernent 24 and the spreader 20 from the handle 4 at its proximal end to be able to pull it out. In this way the internal parts of the stapling instrument 1 can be removed for sterilization.

At the distal end of the shaft tube 2, the head part 12 is screwed on a screw head 35 with the shaft tube. 2 The screw head 35 is in turn bolted to a pipe part 36 that includes the stapler 10, as well as a receiving device for a fluid port 15 °.

The distal Führungselernent 20 of the push rod 28 passes through a bore in the screw head 35 therethrough and can move a stamp 25 in the head member 12 axially in the distal direction. The punch 25 is guided axially in the tubular member 36 and is connected by a rod part 27 with an ejector 26 for the fluid port 15th The pusher 26 forms an abutment surface 31 for a washer 30 which is slidably mounted on the rod member 27th The rod part 27 is surrounded by a compression spring 29, the proximal supported on the die 25 and 30 distal to the annular disc in this way is biased, the annular disk against the stop 31st

The annular disk 30 serves to advance a plurality of spaced around the circumference of the pipe part staple pusher 21 in a distal direction to clamp the fluid port 15 is held in a receptacle 14 by means of brackets in the body surface. The staple pusher are held by the clamp device 14, which has corresponding recesses on its outer circumference, in each of which a bracket 18 and proximally from the clip 18, a clip pusher is arranged 21st

Upon actuation of the pivotable lever portion 6, the push rod is advanced in the distal direction 28, so that the guiding element 20 acts on the plunger 25, and these advances in the distal direction. With the punch 25 and the annular disc 30 is pushed against the staple slider 21 until it makes contact, so that initially the staples are pushed through the mounting tabs 17 eighteenth

The receiving device 14 is fixedly connected to the tubular part 36th In the axial grooves 37 on the outer periphery of the flexible receptacle 14 holding springs 33 are arranged which engage behind the fluid port 15 against an annular edge 34 and hold it in position during the stapling operation. Fig. 3 shows in phantom the position of the Klammerschie- bers 21 18 prior to pushing the clips for clamping with the body tissue, the head portion is placed on the body surface 12, and as shown in Fig. 5, by further actuation of the lever portion 6 of the staple pusher 21 is further advanced. The Befe- stigungslaschen 17 have two inner webs 19, to let in connection with the projections 42 of the staple pusher 21, a bending of the staple legs 23 such that the staple legs overlap in the body tissue 23, and thus a firm anchorage of the fluid ports 15 on the to let muscle surface. After clamping the pusher 26 is brought into contact with the fluid port, so that it is ejected from the head portion 12 by further operation of the lever part. 6 The holding springs are bent apart and possibly 33. bent.

The illustrated in FIGS. Fluid port 15 shown 7 and 8 comprises a preferably cylindrical chamber open on one side 50 which is closed by a self-sealing silicone plug 54th A metal sleeve 66 summarizes the silicone plug 54 and a securing it to the housing of the fluid ports 15 °.

three mounting plates 17 are integrally formed on the housing made of polycarbonate, which, as already stated, are required for clamping. From the fluid port 15 side, a hose connection 58 is now connecting the chamber 50 with an unillustrated hose. The metal sleeve 66 forms at its distal end, the annular edge 34, which is required for the retaining springs 33 of the holding device. 13 Fig. 9 shows a section along the line IX-IX in Fig. 8, wherein it can be seen that the webs 19 closer together stand out as the staple legs 23 of the clip 18. In this manner, with the aid of the projections 42 of the clamp slide 21 a torque on the staple legs 23 are applied, which allows a bending of the staple legs 23rd

Fig. 10 shows a section through the head portion 12 at the distal ends. It is seen that the staple pusher are arranged in recesses of the receiving part 14 schwalbenschwanzformigen 21st Between the staple pushers 21 14 grooves 37 are provided for receiving the retaining springs 33 in the receiving device.

After use, the surgical stapling instrument of the head part 12 can be unscrewed and disposed of, while the remainder of the instrument can be reused by sterilization.
