Abstract
The invention discloses a vascular puncture electro-coagulation needle, which comprises a puncture needle, an insulating bushing, a puncture needle handle, a metal guide wire, an electrode handle and an electro-coagulation electrode, wherein the insulating bushing is sleeved on the middle lower part of the puncture needle; the puncture needle is electrically connected with the metal guide wire and the electro-coagulation electrode; the electro-coagulation electrode is an electric knife electrode and is provided with metal screw; the metal guide wire is connected to the electro-coagulation electrode through the metal screw; and the upper end of the electro-coagulation electrode is provided with the electrode handle. According to the instrument, a puncture method is adopted, the damage is minor, no complicating diseases are caused for the cuts, and no injury of nerve is caused. Meanwhile, the vascular puncture electro-coagulation needle has the advantages of simple technology, low cost and suitability for promotion in most of primary hospitals.
Description
Technical field
The present invention relates to one for operating theater instruments, the especially operating theater instruments of vascular puncture coagulation combination.
Background technology
The large incision in treatment of tradition of the operation of great saphenous varicose vein (PVV) is eliminated.The general miniature incision operative treatment that adopts, generally takes segmentation at present, the method for the little otch excision of multiple spot.At cirso-place, make several little otch that are about 0.5 centimetre especially, slightly do subcutaneous separation, cirso-is slowly taken out by otch, cut off, ligation and excision.Can also, by the cooperation between 2～3 otch, the cirso-within the scope of this be excised completely.The method of the little otch of this multiple spot excision cirso-, due to Wicresoft's wound, otch is little and receive an acclaim.
But this kind of method has operative incision, still have the bad possibility of the healing such as postoperative infection, cicatrix.When peeling operation cirso-, also may damage tegumentary nerve, cause postoperative long-term mono-anesthesia possibility.Meanwhile, for tiny cirso-, peel off difficulty, also have certain residual possibility.
In recent years, occurred the treatment PVV such as laser, had Wicresoft's feature, but still had limitation aspect the complicated PVV of processing, expense is high simultaneously, and technology is more complicated.
Although the existing trocar is of a great variety, not Special surgical instrument, realizes coagulation function technical sophistication.There is not at present the relevant equipment that is exclusively used in PVV operation puncturing pin to occur, make patient have sensation unable to do what one wishes, the operation of impact operation and operation quality.
In addition, although electric knife and coagulation operation are widely used in operation, the maximum output of power of electric knife can reach 150W, and the power of coagulation is smaller, and the frequency of the two use generally, more than 10K, is not the electric knife equipment of free needle construction.
Summary of the invention
The present invention seeks to: the electric knife equipment that proposes a kind of empty needle structure.Especially vascular puncture coagulation pin, in conjunction with the dual-use function of vascular puncture and coagulation, and convenient operation, reliable operation, conveniently completes vascular puncture coagulation dual-use function, is suitable for and can be exclusively used in the related equipment of PVV operation puncturing pin.
Technical scheme of the present invention is: vascular puncture coagulation pin, comprises puncture needle 1, insulated sleeve 2, puncture needle handle 3, wire guide 4, electrode handle 6, coagulating electrode 7; The middle and lower part socket insulated sleeve 2 of puncture needle 1, puncture needle 1 is electrically connected with wire guide 4 and coagulating electrode 7,
Coagulating electrode 7 is standard electric knife electrode; Be provided with metal spiral 5, wire guide 4 by metal spiral 5, be connected to coagulating electrode 7, the upper end of coagulating electrode 7 is provided with the electrode handle 6 of insulation.
Puncture needle tail end 8 can be connected to syringe.
Puncture and coagulation by the front end of puncture needle 1, the adiabatic insulation of insulated sleeve 2 on puncture needle 1 top; Wire guide 4 is electrically connected to coagulating electrode 7(by electrode handle 6 through puncture needle handle 3 and metal spiral 5).Puncture needle tail end 8 can be connected with syringe the steady and calm of guarantee operation, is the good device of executing patient.
Beneficial effect of the present invention is: the electric knife equipment that has proposed a kind of empty needle structure.Especially vascular puncture coagulation pin, the dual-use function of the ingenious combination vascular puncture of the present invention and coagulation, and convenient operation, reliable operation, conveniently completes puncture and the coagulation function of varicose vein operation.
The Special surgical instrument that the present invention proposes in conjunction with puncture electric coagulation therapy PVV according to traditional small incision surgery is the better selection for the treatment of PVV.By adopting trocar puncturing shank cirso-, progressively coagulation sealing cirso-.Apparatus of the present invention adopts piercing method, damages smallly, and non-incision complication, can not cause nerve injury.Meanwhile, technology is simple, and expense is lower, is suitable for promoting at vast basic hospital.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in the figure, vascular puncture coagulation pin comprises puncture needle 1, insulated sleeve 2, puncture needle handle 3, wire guide 4, metal spiral 5, electrode handle 6, coagulating electrode 7, puncture needle tail end 8.
Insulated sleeve is that the plastics of excellent performance are made, and requires suitable heat resistance, especially fluoroplastics or polyphenylene sulfide to make; Puncture needle adopts rustless steel preparation, and the syringe needle of needle tip is sharp, and incisxal edge is smooth.Pin footpath is 12-26G, without specific limited, the length of pin is 10-20cm, No. 18--22, pin footpath, especially 20cm of the length of pin, puncture needle handle mostly is plastics, main as the handle of puncture vessel and through wire guide 4, wire guide 4, metal spiral 5 are electrically connected to coagulating electrode 7, and metal spiral can make puncture needle can extend in length and be unaffected, maybe can make puncture needle use time, are not subject to involving of coagulating electrode 7.Coagulating electrode 7 connects the electric outputting standard interface of existing electric knife or Electrocoagulation equipment, (for example adopt existing electric knife handle, be provided with wire and be connected electric knife electricity outut device with control line).
Puncture needle tail end 8 or be connected to syringe, be provided with drainage tube or be connected to negative tube.
