Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for loading C-shaped scalp clips into the magazine of a scalp clip applicator.

In the case of an applicator for scalp clips, such as is known from JP-A-60-111649, the scalp clips must be inserted individually into the magazine by hand. This is time consuming, requires manual dexterity, and often cannot be done under sterile conditions.

It is an object of the present invention to provide a 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 that the scalp clips are arranged in a supply container one after the other in rows, the supply container is connected to the supply opening of the magazine, and the scalp clips are 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 clips can be transferred from the container to the magazine in a very simple manner under sterile conditions again.

The apparatus for carrying out this advanced method is such that a supply container accommodates a row of scalp clips, and insertion means are provided on the magazine for connecting the supply container to the magazine, whereby the scalp clips are removed from the supply container. It is characterized by being transferred from one magazine to 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 in the cover, which at the same time holds the cover in the 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.

Scalp clip applicator 1 shown in Figure 1
has a handle 2 and an actuation pawl 3 pivotally mounted thereon. A magazine 4 that freely protrudes forward and has a U-shaped cross section is attached to the handle 2.
is connected to. This magazine holds C-shaped scalp clips in a manner known per se, which are ejected individually from the front open end 5 of the magazine. 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 Figure 1, the housing 6
only visible, which surrounds a roll spring that is wound and unwound in the form of a tape measure.

As shown in the figure, the housing 6 is movable within the sliding guide surface 7 towards the rear part of the magazine and is in the operating position (FIG. 4) and in the filling position (first and second positions).
and FIG. 3) and can be moved back and forth between the two positions and can be 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 supply 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 curves of the bridges of the preceding scalp clip, thereby causing the clips to be tightly packed one after the other in the magazine. Scalp clip 1 in supply container 11
2 is similar to the scalp clip after being inserted into the magazine 4. The supply container 11 can be closed by an attachable 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 disinfected when placed in supply container 11 which is continuously closed by cover 16.

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

The interconnection between magazine 4 and supply container 11 is first formed in the position shown in FIG. 2, i.e. magazine 4 is tilted slightly upwards and supply container 11 is held essentially horizontally; This prevents the scalp clip 12 from sliding out of the container. Once the container 11 is inserted into the magazine 4, it can be tilted as shown in FIG. The scalp clips 12 thus slide out of the container 11 into the magazine 4 without changing their order and separating from each other until the magazine is completely filled.

Once the container 11 is emptied, the magazine 4
from the insertion means. 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, due to the pressure exerted by the roll spring, pushes the scalp towards the front open end 5 of the magazine 4. The entire row of clips can be energized. The clips can then be ejected one after another when the pawl 3 is actuated.

In the embodiments 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 .
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 the container 1
1, so that the cover 16 (see FIG. 6) can be opened upwardly to release the outlet opening of the supply container 11.

The two protrusions 27 are located on the upper wall portion 2 of the cover 16.
Extends laterally from 3. 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 portions 18,19. These surfaces extend downwardly and are sloped towards the rear. These abutment surfaces interact with the projections 27 when the container is introduced into the insertion means, so that the projections 27 slide upwardly along these surfaces 28. The cover 16 is then opened automatically, and the outlet opening in the end face of the container 11 is free, and the scalp clips 12 can be removed from the container 11 to the magazine 4 without changing their order or 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 ejected from the container prematurely.

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;
This allows the cover 16 to pivot to the container 1.
Mounted on 1.

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 provided in a simple manner by a plastic hinge formed of a corresponding design. It is also possible to provide above the supply container 11 a coil spring, for example made of plastic, the free end of which presses onto the upper wall portion 23 of the cover 16 and maintains the cover in the closed position.
