Abstract

The invention provides a minimally invasive endoscopic electrode which comprises an electrode pin, an electrode handle and an electrode body, wherein the electrode pin is connected together with the electrode body. The minimally invasive endoscopic electrode is characterized in that the length of the electrode body is 30-55cm, an insulating layer is sheathed on the electrode body, and a contact is exposed at the end part of the electrode body. The minimally invasive endoscopic electrode has an artful structure with the lengthened electrode body, thereby solving the problem of hemostasis in minimally invasive endoscopic surgeries such as hemostasis failure in a kidney tissue in mini-invasive percutaneous nephrolithotomy (MPCNL) and percutaneous nephrolithotomy (PCNL); the nephrolithotomy is safer, more minimally invasive and more thorough with the help of thorough hemostasis in the nephrolithotomy, and fully tubeless PCNL is realized after the nephrolithotomy, thereby greatly improving the surgical effect; the electrode is operated by the handle with a control button of the electrode, and eye-hand coordination is superior to eye-foot control so that bleeding points are solidified in case of touching, thereby being efficient and accurate; and the electrode can be matched with all standard electrotomes and can be used on the existing equipment in the hospital, thus the electrode has strong universality and is economical and practical.

Description

A kind of Wicresoft chamber mirror electrode

Technical field

The present invention relates to a kind of electrode, particularly a kind of Wicresoft chamber mirror electrode.

Background technology

Existing standard electric knife is widely used in each large and small hospital, and the length of its electrode body is lacked (generally having only 3～5 centimetres), only is applicable to the various minor operations of epidermis, has the electric coagulation hemostasis effect.But be not suitable for all endoscope-assistant surgeries.

Though some import plasma hemostasis equipment are arranged, also can solve hemostatic problem in Wicresoft's endoscope-assistant surgery.But import plasma hemostasis equipment price costliness needs to buy special-purpose generator and dedicated handle, can not utilize hospital's existing equipment.And import plasma hemostasis equipment adopts foot-operated control, because the art middle kidney with respiratory movement, adds that the Wicresoft visual field is little, the petechia blood flow disturbs, and is easy to lose electric condensation point.

Summary of the invention

The object of the present invention is to provide a kind of simple in structure, the length of the electrode body that extended, thus can solve hemostasis problem in Wicresoft's endoscope-assistant surgery; And highly versatile, economical and practical, easy to operate, efficiently and accurately Wicresoft chamber mirror electrode.

Purpose of the present invention can reach by following measure: a kind of Wicresoft chamber mirror electrode, comprise electrode foot, electrode handle, electrode body, electrode foot and electrode body are connected as a single entity, it is characterized in that: the length of electrode body is 30～55 centimetres, be with insulating barrier thereon, and expose the contact in the end of electrode body.

Purpose of the present invention can also reach by following measure: the diameter of electrode body is 1.5～2 millimeters.The length of contact is 3～5 millimeters.Electrode handle is made by insulant, is placed on the electrode foot.Electrode foot and working standard electric knife handle are pegged graft.

The present invention has following advantage compared to existing technology:

1, structure is ingenious, the length of the electrode body that extended, thereby solved a hemostatic difficult problem in Wicresoft's endoscope-assistant surgery, as at micro channel via-skin kidney mirror lithotomy, in the percutaneous nephrolithotomy, can not a hemostatic difficult problem to nephridial tissue, by thoroughly hemostasis in the art, make operation safer, more Wicresoft, to get stone more thorough, postoperative can accomplish not have pipeization fully, improves surgical effect greatly.

2, employing is lever operated, and just on handle, eye-hand coordination is better than a foot control system to the electrode control knob, petechia one is touched promptly coagulate efficiently and accurately.

3, can match with all standard electric knifes.Because operation principle is different with import plasma hemostasis equipment, does not need dedicated handle, does not need to buy in addition special-purpose generator.On hospital's existing equipment, can use, highly versatile, economical and practical.

4, can be widely used on the mirror of any chamber: as PCN, Li Xunjing, ureteroscope etc.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is that the A-A of Fig. 1 is to the structure cutaway view;

Fig. 3 is that the B-B of Fig. 1 is to the structure cutaway view.

The specific embodiment

The present invention is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1-Fig. 3, the present invention includes electrode foot 1, electrode handle 2, electrode body 3, insulating barrier 4, standard electric knife handle etc.The length of electrode body 3 is 30～55 centimetres, and diameter is 1.5～2 millimeters; Be with insulating barrier 4 thereon, and expose contact 3-1 in the end of electrode body 3; The length of contact 3-1 is 3～5 millimeters.Electrode foot 1 is connected as a single entity with electrode body 3, and its diameter is thicker slightly than electrode body 3; : electrode handle 2 is made by insulant, is placed on the electrode foot 1.

During practical operation, after electrode foot 1 inserted working standard electric knife handle, adopt standard electric knife principle: promptly patient body will connect negative plate, handle will link to each other with the electric knife main frame with negative plate, during generation, electrode contact tissue and negative plate produce the loop, and the electric coagulation hemostasis effect takes place.Electrode body 3 stretches in the mirror of long chamber and (all can operate in all chamber mirrors), is electrified in petechia in all endoscope-assistant surgeries and coagulates anastalsis, is used in particular for Minimally Invasive Surgerys such as PCN, Li Xunjing, ureteroscope.As at micro channel via-skin kidney mirror lithotomy, in the operation such as percutaneous nephrolithotomy (PNL), to nephridial tissue petechia electric coagulation hemostasis.
