SPECIFICATION

Vein stripper 1 10 This invention relates to a surgical instrument 70 and in particular an instrument for stripping veins.

As far as the applicant is aware varicose veins, particularly the saph enous veins, are conventionally stripped by making incisions in the skin, usually at the thigh and at the ankle, to expose the ends of a portion of a vein to be stripped. The exposed ends are then cut and a wire is passed through the portion to be stripped. The end of the vein is then tied to the wire and the vein is removed by pulling the wire out. In this process branches from the parent vein are avulsed with some atten dant bruising.

This conventional method is not entirely 85 satisfactory. The wire may not be able to pass through the vein due to excessive tortuo sity or previous thrombosis. The vein some times tears with the result that only a portion of it is rem oved. The operation may aggravate existing degenerative skin conditions. The in ternal stripper does not lend itself to easy removal of a duplex saphenous system nor stripping of major branches. The operation may cause injury to the saphenous nerve since this nerve lies close to the vein in the leg and foot. In the conventional method all of the vein is removed. In the case of the saphenous vein this is not always necessary if there is no disease around the ankle. Since the lower segment of the saphenous vein is used in triple bypass procedures on the vessels of the. heart there is good reason to preserve it.

It is believed that these problems have tended to discourage surgeons from perform- ing- enthusiastically surgery on varicose veins It is sought to solve at least some of them by providing an instrument which may be used in vein stripping.

According to the invention there is provided a vein stripper comprising a shaft and., adja cent one end of the shaft, a passage having an axis which is, or has a component which is, parallel to the shaft.

According to one aspect of the invention the passage is formed in a projection which is disposed transversely to the shaft and the passage is disposed transversely to the said projection.

The projection may be substantially perpen- 120 dicular to.the shaft.

It is preferred that the vein stripper has a handle at the end of the shaft opposite the projection.

In a preferred aspect of the invention, the projection comprises a face at which one end of the passage opens and part of the face adjacent the said one end of the passage is sharpened to constitute a cutting edge.

According to various alternative aspects of the invention, the length of the shaft is about 90 mm, 350 mm or 500 mm. Advantageously, no part of the cranked portion out of alignment with the shaft has, according to yet another aspect of the invention, a transverse dimension greater than about 7 mm. The diameter of the shaft is advantageously about 4.7 mm or, where the shaft is of short length, about 3.0 mm.

The invention is further discussed with reference to the accompanying drawings in which an embodiment of the invention is described by way of example, and in which Figure 1 is a view from the side of a vein stripper; Figure 2 is an enlarged view of one end of the vein stripper; Figure 3 is a cross sectional view of the same one end of the vein stripper; and Figure 4 is a sketch of the manner of use of the vein stripper.

In - the drawings, there is shown a vein stripper 10 comprising a slim, elongate shaft 12 with a handle 14 at one end and a cranked portion forming a head 16 at the opposite end. In the illustrated embodiment the length of the shaft is 350 mm and the diameter thereof is 4.7 mm. The head 16 is disposed in the illustrated example at 90 degrees to the shaft 12. The head is upset which is to say it is formed so that transverse to the axis of the shaft it is approximately circular and has a diameter somewhat larger than the diameter of the shaft, conveniently 8 mm. A passage 18 is formed in the head. The diameter of the passage in the illustrated embodiment is 6.3 mm which is considered to be an optimum diameter to enable varicose veins which are to be stripped with the use of the stripper.to be passed into and through the passage. The axis of the passage 18 is parallel to that of the shaft 12 in the illustrated example. The head has a face 20 which faces away from the shaft and, where it meets the passage, this face is sharpened to form what in use is a cutting edge 22.

In use a groin incision is made and the long saphenous vein is dissected free by ligating and dividing its branches locally.. The saphenous vein is ligated at its point of junction with the deep vein and then divided, A small incision is made over the inner side of the ankle and the lower end of the long saphe_nous vein is isolated. A conventional internal stripper may then be passed up the vein and the vein avulsed by pulling the wire in the usual way.

If any difficulties are encountered at any stage immediate use is made of the vein stripper described, which will be called for convenience an external stripper. Alternatively, the external stripper can be used ab initio. Here, after making the incisions as described above the end 24 of the portion of vein at the ankle 2 GB2195540A 2 is passed through the passage 22 of the stripper. The end 24 is then firmly held and the head of the stripper is worked into the leg and along the vein which passes through the passage 18 in the process. As it goes the cutting edge 22 severs branch veins (as shown by way of example at 26). When the surgeon judges that the stripper has been passed far enough along the vein (this being governed, obviously, by how much of the vein is to be removed), the external stripper is withdrawn and the vein is removed either by simply drawing it out or by using a vein hook such as that described in the applicant's co- pending United Kingdom patent application entitled---VeinHook---.

The length of the handle is important principally for the 'fee]' of the instrument. In the present case the length may for example be 100 mm. The diameter is 9.5 mm; this should not be exceeded by much more than about 5 mm since the handle lies close to the leg and follows the shaft along the leg in operation. A flat 28 is formed in- the handle in alignment with the he ad 16. This enables the surgeon to judge the orientation of the head on the shaft when the head cannot be seen. A transverse passage 30 is formed in the free end of the handle. This passage enables the instrument to be hooked by an extractor for removal 95 from the leg.

It is envisaged that a set of three external strippers will usually be provided, differing one from the other only in size. One instrument of the set will be longer than that described - -above. Its shaft length will be 50Omm and the handle length may be somewhat greater.

Apart from these factors the instrument with the long shaft is substantially identical to that show n in the drawings. The advantage of the - longer instrument is that it can pass from the groin to the ankle.

The third instrument in the set is smaller, with proportions differing from the drawings.

The shaft length will be 90 mm with a; dia meter of 3.0 mm. The diameter of the pas sage in the head will be 4.0 mm and the diameter of the head itself 5.3 mm. This in strument has a slightly different function from those first described in that it is used to strip out segments of vein in other parts of the leg, the head being capable of being passed through an incision 4.0 to 6.0 mm long. It may also be used to strip out small segments of vein under local anaesthetic.

The length of the instrument shown in the drawings (i.e. the medium-sized instrument) is ideal for stripping the short saphenous vein in the back of the leg. - Preferably the shaft should in any case be as slim as possible. It is necessary that if should be strong enough to fulfil its function and for this reason, as well as for ease of sterilising, the stripper is desirably of polished stainless steel.

Preferably also the overall transverse size of the head of the stripper should be as small as possible. This size is governed by the size of the passage and the thickness of the material therearound necessary to enable the head to be strong enough to fulfil its function.

While the head is shown perpendicular to the shaft and the axis of the passage parallel to the that of the shaft, these may not be essential characteristics. Particularly as regards the disposition of the passage, some deviation therefrom may be tolerated.
