DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for loading a C-shaped scalp clip into a magazine of a scalp clip applicator, and also to an apparatus for carrying out such a method.

In the case of an applicator for scalp clips, as known for example from DE-P 53405335, the scalp clips have to be inserted individually into the magazine by hand. This is time consuming, requires manual dexterity,
Often cannot be performed under sterile conditions.

It is an object of the present invention to provide a method and device that allows a scalp clip applicator to be quickly loaded with a C-shaped scalp clip while maintaining sterile conditions.

The present invention provides for the scalp clips to be arranged in a supply container one after the other in rows, the supply container being connected to the supply opening of the magazine, and the scalp clips being transferred from the supply container to the magazine without changing the order. This is accomplished according to progressive methods. The supply container can, for example, be loaded with scalp clips at the factory and then delivered pre-sterilized. In the field, for example in the operating room, the scalp clip can be transferred from the container to the magazine in a very simple manner under sterile conditions again.

The apparatus for carrying out this inventive method comprises: a supply container housing an array of scalp clips; insertion means are provided on the magazine for coupling the supply container to the magazine;
This is characterized in that the scalp clips are transferred from the supply container to the magazine one after another.

It is particularly advantageous in that the scalp clips slide from one supply container to another into the magazine under the influence of gravity.

The supply container is preferably tubular in design and is closed at its front end with a cover.

In a preferred embodiment, the inventive device comprises a roll spring housing mounted on the magazine for movement, wherein the insertion means on the magazine have a closable insertion opening and at least one support for a supply container; It is characterized in that the insertion opening can advantageously be closed by.

In a preferred embodiment, the cover is articulated on the supply container and opens automatically for interaction with the insertion means when the container is inserted into the magazine.

In a preferred embodiment of the invention, the cover is biased to a closed position. The cover is advantageously provided with at least one projection and insertion means and an abutment surface for this projection, so that when the container is inserted into the magazine the projection engages the abutment surface and Lift the cover to the open position. Preferably, the cover is formed of a plastic material and is connected to the supply container via a plastic hinge integrally formed on the cover, whereby the plastic hinge simultaneously holds the cover in a closed position. It can provide a biasing force to do so.

Eventually, the cover may also be pivotally attached to the supply container by means of a pivot pin.

The following description of preferred embodiments, together with the accompanying drawings, serves to explain the invention in more detail.

The scalp clip applicator 1 shown in FIG. 1 includes a handle 2 and an actuating pawl 3 pivotally mounted thereon.
and has. A magazine 4 which freely projects forward and has a U-shaped cross section is connected to the handle 2. This magazine holds a C-shaped scalp clip in a manner known per se, the C-shaped scalp clip being located at the front open end 5 of the magazine.
are discharged separately from the When the pawl 3 is actuated, the scalp clip can be connected to the tissue part (skin of the scalp).

The scalp clips are placed one after the other in the magazine and are urged towards the open end 5 of the magazine by a roll spring placed at the rear end of the magazine 4. In FIG. 1 only the housing 6 is visible, which encloses a roll spring that is wound and unwound in the form of a tape measure.

As shown in the figures, the housing 6 is movable within the sliding guide surface 7 towards the rear part of the magazine and between the working position (Fig. 4) and the filling position (Figs. 1, 2 and 3). It can be moved back and forth and attached to each position.

FIG. 2 shows the rear part of the magazine 4 with a roll spring housing 6, the front end of which has a stop 8, which is movable under the pressure of the spring. The delivery container 11 accommodates scalp clips to be applied one after the other in a magazine. Each scalp clip 12 has a pair of gripping jaws 13, 14 which rest resiliently against each other and a curved bridge 15 connecting these gripping jaws. The gripping jaws of each successive scalp clip engage the rear curve of the bridge of the preceding scalp clip, thereby tightly packing the clips one after the other in the magazine. supply container 1
The arrangement of the scalp clip 12 within the magazine 4 is similar to that of the scalp clip after being inserted into the magazine 4. supply container 1
1, the mounting can be closed by a universal cover 16. The container 11 and the cover 16 are tubular in design and have a square or rectangular cross section. Scalp clip 12 is cover 1
6, it is sterilized when attached to the supply container 11 which is continuously closed.

Insertion means for the supply container 11 are provided on the magazine 4. It has a recess 17 in the bottom of the magazine 4 and two wall sections 18, 19 which are directed upwardly in the form of a funnel and are bent inward at an angle. The dimensions are such that the cover can be inserted with an open part between the wall part 18, 19 and the recess 17 for self-retention once removed. This results in
The lower wall 21 of the supply container 11 rests on two flanges 20 forming a support and projecting inwardly from the side walls of the magazine 4 . Furthermore, the lower wall 2 of the supply container 11
1 may abut the outer surface of the housing 6. Overall, the supply container 11 is in any case firmly connected to the magazine 9 via the previously described insertion means.

The interconnection between the magazine 4 and the supply container 11 is the second
The position shown in the figure is first formed, ie the magazine 4 is tilted slightly upwards and the supply container 11 is held essentially horizontally, so that the scalp clip 12 cannot slip out of the container. Once the container 11 is inserted into the magazine 4, it can be tilted (as shown in FIG. Slide out from 11 to magazine 4.

Once the container 11 has been emptied, it is withdrawn from the insertion means of the magazine 4. The housing 6 is then moved from the position shown in FIG. 2 or 3 to the position shown in FIG. 4 and installed in position. This means that the rear feeding opening of the magazine formed by the insertion means is closed and the scalp clip 12 cannot fall out.

A stopper 8 connected to a roll spring housed in the housing 6 abuts the rearmost end of the scalp clip 12 and causes the scalp clip to move toward the front open end 5 of the magazine 4 due to the pressure exerted by the roll spring. All columns can be energized. The clips can then be ejected one after another when the pawl 3 is actuated.

In the embodiment shown in FIGS. 5 to 7, the supply container 11 can be closed by a cover 16 which is articulated on the supply container 11. In the embodiment shown in FIGS.

The cover 16 has a closure member 22 for closing the end opening of the supply container 11. The wall portion 23 of the cover 16 abuts the upper wall 24 of the container 11.

The cover 16 is made of plastic and is integrally connected to the plate 26 via a plastic hinge 25.

This plate 26 is firmly connected, e.g. attached, to the upper wall 24 of the container 11, so that the cover 16 (sixth
(see figure) can be opened upwards to release the outlet opening of the supply container 11.

Two projections 27 extend laterally from the upper wall portion 23 of the cover 16. These have the shape shown in the figures and extend along the side walls of the container 11.

An abutment surface 28 is provided on the wall portion 18.19.

These surfaces extend downwardly and are sloped toward the rear. These abutment surfaces interact with the projection 27 when the container is introduced into the insertion means, so that the projection 2
7 slides upwards along these surfaces 28. The cover 16 is then automatically opened and the outlet opening on the end face of the container 11 is free and the scalp clips 12 can be moved from the container 11 to the magazine 4 without changing their order and separating from each other until the magazine is completely filled. It is possible to slip out.

Figures 5 and 6 show that the cover 16 reaches its fully opened position when the container 11 is correctly inserted into the magazine 4. This means that the scalp clip 12 cannot be prematurely ejected from the container.

Another embodiment is shown in FIG. 7 which essentially differs from that of FIGS. 5 and 6 in that the cover 16 has, in addition to the plastic hinge 25, a set of inwardly projecting pivot pins 29. These pins engage corresponding openings in the side wall of the supply container 11, whereby the cover 16 is mounted on the container 11 for pivoting.

The cover 16 is preferably constantly biased in the closed position by a spring so that the scalp clip 12 cannot inadvertently slip out of the container 11. The biasing force required for this can be supplied in a simple manner by a plastic hinge formed of a corresponding design. Container 1 for supplying coil springs made of plastic, for example.
1, the free end of which presses onto the upper wall portion 23 of the cover 16 and maintains the cover in the closed position.
