Abstract

The utility model provides a varicose vein exfoliative device, which is characterized by comprising a plastic catheter; a first guide head and a second guide head are respectively arranged at two ends of the plastic catheter; two opposite conical heads are arranged in the middle section of the plastic catheter; and a clamping groove is formed between the two conical heads. The varicose vein exfoliative device disclosed by the utility model is simple in structure and is safe to operate. Veins of different varicose degrees can be successfully guided out and reliably exfoliated.

Description

A kind of cirso-stripper

Technical field

This utility model relates to a kind of apparatus that unusual cirso-in the human body is stripped off, and belongs to technical field of medical instruments.

Background technology

Varicosis is one of modal peripheral vascular disease; It mainly is to be more common in lower limb great saphenous vein and/or small saphenous vein, and the classic treatment method is to adopt great saphenous vein root high ligation, and great saphenous vein and varicose branch thereof are stripped off operative treatment; The apparatus of its use is the finer wire that a two is the half elliptic ferrule; Exposing and cutting off the latent greatly far and near end of vein of opening of limbs, guide head is penetrated from venal distal to be stripped off, near-end is to deriving; Slowly pull out then, utilize to turn in the guide head and strip off great saphenous vein.But the finer wire compliance of band ferrule is poor, the easy damaged PeV, and the operation medium-sized vein is prone to come off or problem such as fracture; And as using medical apparatus and instruments in the human body; Disposable use should be the safest, the use of sterilizing repeatedly of existing metal steel wire vein stripper, easy infection; The corrosion of multiple high temp autoclave sterilization ageing of metal is prone to produce potential safety hazard.

Summary of the invention

The purpose of this utility model provides the reliable cirso-stripper of a kind of handling safety.

In order to achieve the above object; This utility model provides a kind of cirso-stripper; It is characterized in that, comprise plastic catheter, the two ends of plastic catheter are respectively equipped with first guide head and second guide head; The stage casing of plastic catheter be provided with two back to conical head, be formed with draw-in groove between two conical heads.

Preferably, described plastic catheter has scale.

Preferably, described first guide head is a linear, and second guide head is a circular arc.

Preferably, described draw-in groove is 4-8mm along the yardstick of plastic catheter bearing of trend.

Compared with prior art, the utlity model has following beneficial effect:

1, at the draw-in groove place and the conical head top carry out dual silk thread ligation and fix, make vein be difficult for slippage, guarantee operation smoothly, safety carries out; And pathological changes venectasia degree no matter, fixedly wall of vein is in conical head and draw-in groove place to have used the silk thread ligation, and an operation only gets final product with a stripper, has shortened operating time, has alleviated patient's misery and burden;

2, have the degree of depth that graduated conduit can estimate to insert cirso-accurately, avoid being strayed into deep veins of lower limb or guide head mistake and penetrate branch vessel, and medical error takes place;

3, have two kinds of guide heads, for the vein of different degrees of expansion, stripper all can be derived in cirso-smoothly;

4, use plastic material, increased the smoothness and the pliability of operation, also can reduce than the metallic weapon cost;

5, simple in structure, be convenient to the operation.

Description of drawings

Fig. 1 is a cirso-stripper structural representation;

Fig. 2 uses sketch map for the cirso-stripper;

Fig. 3 derives sketch map for the linear guide head;

Fig. 4 derives sketch map for the circular arc guide head.

The specific embodiment

Specify this utility model below in conjunction with embodiment.

Embodiment

As shown in Figure 1; Be cirso-stripper structural representation; Described cirso-stripper is made up of first guide head 1, plastic catheter 2, conical head 3, draw-in groove 4 and second guide head 5, first guide head 1, plastic catheter 2, conical head 3, draw-in groove 4 and second guide head 5 all adopt biocompatibility preferably non-toxic plastic process, plastic catheter 2 has scale; Its two ends are respectively equipped with second guide head 5 of rectilinear first guide head 1 and circular arc; The stage casing of plastic catheter 2 be provided with two back to 3, two conical heads 3 of conical head between be formed with draw-in groove 4, draw-in groove 4 is 6mm along the yardstick of plastic catheter 2 bearing of trends.

As shown in Figure 2, for the cirso-stripper uses sketch map, during use; Operation high ligation great saphenous vein and affiliated expose the far and near end of great saphenous vein, and far-end inserts first guide head 1; Observe the scale on the plastic catheter 2, note insertion depth, derive by the great saphenous vein near-end; The conical head 3 that will be positioned at the conduit stage casing places the pathological changes vein terminal; On draw-in groove 4 and conical head 3 tops respectively the silk thread ligation fixedly the cirso-wall on plastic catheter 2, plastic catheter 2 is slowly pulled out together with cirso-by near-end, turn in carrying out and strip off.

If first guide head 1 runs into the tangible vein of tortuous expansion, can't be when tortuous intravenous be derived, as shown in Figure 3, can use the 5 guiding outlets of second guide head instead, as shown in Figure 4, be that the circular arc guide head is derived sketch map, it is the same that vein strips off step.
