Priority: -29. December 1971, Great Britain 60394/71

The present invention relates to an apparatus for removing staples and especially on such for removing viund brackets from an essentially healed wound. . . . -

Certain surgical procedures can cause a wound or an incision can be closed by placing a clip over the mating edges of the wound will. Such a clip usually consists of a curved strip of metal up to about 20 mm in length and 5 mm Width, the one with inwardly directed prongs or points

is provided at each end and this strip is bent across the matching edges of the wound so that the prongs engage the skin and flesh to hold the vurld edges together. The wound clamp wiri ia- 'at as long as ar. Leave the crt ur.d place until the wound has healed, after which it is removed, for example by cutting open the back of the klairr. In a special type of staple, known as C lay-Adams-Klärji er, which is provided with incisions or notches at the ends of the staples, the removal of the same takes place in the manner that the sacks of a cross-tweezer are inserted into the incisions whereupon the forceps are squeezed to remove the ends of the clamp ν one ir. under. The cross-tweezers to be used for this must be sufficiently stable to generate the necessary force. the. to be able to exert ends distant from the pivot point and to be able to do this. Plnzittifi will be used . . re-sterilized with each use.

The present invention now relates to a device for removing wound clips, in particular C lay-Ada. :: s wound clips and the like having notches or incisions at the ends of the clips, these devices are much cheaper to manufacture than the previously used cross tweezers. Such a device k; ir.n are delivered in a sterile package and they are so cheap that they can be thrown away after use and sterilization of the same is not worthwhile.

According to the invention, the removal device has ν a pair of jaws that are normally separated from

The device for removing surgical clips according to the invention consists, as can be seen from Pig # 1 and 5, of a single piece of plastic material which is shaped in such a way that a pair of jaws 1 are formed around a pivot point or hinge 2 are movable. Behind this Q-joint 2 there is a Pederbogen, which consists of a pair of curved parts 3 which are connected to one another at their ends by a further pivot point or a joint 4. This joint "4 is located in the same level as the jaws 1 and the front joint 2 up to 2 cm and the Pederbogen has a transverse extension of 2 to 3 cm »The jaws 1 are separated from each other when the device is not pressed together and the jaw ends are provided with lips 5 which can engage in notches or incisions at the ends of the wound clip In a preferred embodiment, these lips 5 are arranged at an angle of about 45 to the axis of the device, as can be seen from FIG 90 sur Aehue üqv device, as can be seen from Pig. 6.

BAO ORIGINAL

Rigidity of the device around the joint 2 is still increased improved by providing a pair of ribs 6 along the axis of the device, extending from each Ms jaw head extend to about the maximum width of the spring arch along the outside of the device. On the outer surface of the arch parts 3, G-grooves 7 are provided following the ends of the ribs 6. In a further embodiment, on the inner surface of the bent parts at the point of maximum distance the same from each other a stop 8 may be provided.

When a wound clip is removed from an essentially healed wound with the device according to the invention is to be, so the device is between thumb and index finger with one hand. the handle grooves 7 held. The lips 5 of the jaws 1 are then in the notches or Incisions 9 of a surgical clip 10 introduced, as in Pig, is shown. If the lips 5 are arranged at an angle of approximately 45 to the axis of the device, so are the: tips of the surgical clip are clearly visible, so that removal of the same is easier in this case. But when the lips 5 are arranged at an angle of 90 to the axis of the device, so a greater force exercise. The arch parts 3 are then by-a pressure on the grip grooves 7 pressed together so that in this way the jaws 1 rotate outwards around the joint 2, «and the jaws are opened further. The tips of the wound clips 10 are in this case removed from one another, as can be seen from FIG. 4, so that the wound clip 10 is separated from the Fig. 3 and 4 with dashed lines shown skin surface can be removed. The stop 8 between the Arch parts 3 prevents them from being pressed too far together

The device according to the invention can consist of any one thermoplastic material such as high density polyethylene, nylon,

Acetal, polycarbonate, polyethylene terephthalate with or without Fillers, and preferred materials are polypropylene or filled polypropylene, especially with Talc filled polypropylene or nylon, the latter of which Material is particularly preferred. The apparatus can be made by any known technique for making articles made of plastic material, with the injection molding technique being particularly preferred.
