Abstract
The invention relates to a plasma columnar electrode. The plasma columnar electrode comprises a handheld handle and a columnar electrode body. One end of the handheld handle is connected with a power line, and the other end of the handheld handle is connected with the electrode body. An electrode tip arranged at one end of the electrode body is in a convex ball shape, and the diameter of the electrode tip is larger than that of the section of the electrode body. The electrode body is covered with an insulating shell with certain hardness. The plasma columnar electrode can be used for bleeding stop of the percutaneous renal channel in percutaneous nephroseopy lithotripsy, the bleeding stop effect is good, and side injuries can be effectively avoided.
Description
Technical field
The present invention relates to medical instruments field, specifically disclose a kind of plasma columnar electrode.
Background technology
At present, hemorrhage to PCNL (percutaneous nephrolithotomy) middle kidney passage or to place the compressing of kidney stoma passively, uncertain therapeutic efficacy is cut at home, easily occur serious hemorrhage.And plasma columnar electrode (as Fig. 1) itself is for Transurethral Operation is used, and never used at percutaneous nephrolithotomy, though certainly find in clinical practice directly to use these ion prismatic electrodes to stop blooding, but owing to being not specially designed by PCNL hemostasis, therefore there is many deficiencies:
1, the quality of plasma columnar electrode own is partially soft, enters rear to bad control, cause hemostasis operation difficultly time-consuming through kidney mirror inner chamber;
2, electrode tip is column, and be exactly a point-like in fact, plasma electrode own has certain cutting effect, easily falls into into renal tissue deep and cause the generation of Accessory injury during hemostasis;
3, in PCNL art, percutaneous kidney passage is straight, and we need to carry out hemostasis operation is the kidney passage of kidney mirror epitheca periphery, and plasma columnar electrode is straight, kidney mirror epitheca need be exited when this just requires that we stop blooding, and the rightabout to petechia swings kidney mirror afterbody and goes hemostasis again, the swing of kidney mirror will inevitably cause the displacement of corresponding kidney mirror epitheca in nephridial tissue and increase the damage of kidney passage.
Summary of the invention
The object of the invention is to: provide a kind of plasma columnar electrode that is effective, that do not produce Accessory injury that stops blooding in PCNL for overcoming the above problems.
The technical solution adopted in the present invention is such:
Plasma columnar electrode, comprises hand holding handle, columnar electrode, and described hand holding handle one end is connected with power supply wiring, the other end and described Electrode connection; The electrode tip that described electrode one end is arranged is spherical in protruding, and its diameter is greater than described electrode sections diameter; Described electrode package is had the insulation crust of certain degree of hardness.
Further, described electrode tip is that straight peen is spherical or elbow is spherical.
Further, described electrode tip diameter is 2 ~ 5mm.
In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows:
1, the present invention holds harder insulant in plasma columnar electrode periphery, increases its hardness, makes the angle and direction that can be carried out control electrode head end after kidney mirror inner chamber enters by hand holding handle.
2, electrode tip is for protruding sphere pole, increases its contact area with kidney channel organization, main its coagulation effect of performance and the Accessory injury avoided its electrode head end to cave in renal tissue and cause.
3, electrode tip is for protruding sphere pole, and surface, in arc-shaped, can reduce or avoid the swing of kidney mirror to the damage of kidney passage when stopping blooding like this.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in figures 1-4, a kind of plasma columnar electrode, comprises hand holding handle 1, columnar electrode 2, and described hand holding handle 1 one end is connected with power supply wiring 3, and the other end is connected with described electrode 2; The electrode tip 4 that described electrode 2 one end is arranged is in straight peen spherical (Fig. 2) or elbow spherical (Fig. 3), and its diameter is greater than described electrode 2 diameter of section, but is less than the internal diameter (Fig. 4) of kidney mirror passage; Described electrode 2 wraps is had the insulation crust of certain degree of hardness.
Described electrode tip diameter is 4mm, and the diameter of kidney mirror passage is 8mm, more conveniently puts into kidney mirror and therefrom takes out, and can be convenient to hemostasis operation again.
Electrode tip 4 is designed to spherical in the present invention, one can avoid in use oppose side wall tissue to stab, two increase and can to prevent with tissue contact surface electrode tip 4 end to cave in the Accessory injury that may cause, and three are convenient to take out electrode 2 after use terminates, and avoid being blocked by kidney mirror luminal border; Sphere pole head 4 comparative electrode 2 protrudes, just can stop blooding to the kidney passage of kidney mirror epitheca periphery without inclined electrode, avoid and need go to swing kidney mirror to observe columnar electrode head end to the opposite direction of petechia, also the nephridial tissue Accessory injury that the swing with regard to avoiding kidney mirror causes kidney mirror epitheca to cause at nephridial tissue intrinsic displacement, simple and practical; Bag is had the insulant of certain degree of hardness, can improve the hardness of electrode 2, makes it come direction and the angle of control head termination electrode in operation easily via the adjustment of rear hand holding handle 1.
Plasma columnar electrode of the present invention can be used for stopping blooding to percutaneous kidney passage in percutaneous nephrolithotomy, can avoid in this operation, placing the uncertain therapeutic efficacy of kidney stoma suppression techniques passively to cut, the problem of kidney passage this postoperative complication hemorrhage easily occurs.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
