The resection electrode types include: a hand-crafted, temperature-resistant tungsten wire-cutting loop; a coagulating perforated resector that provides a 40% greater coagulation zone than standard cutting loops and performs cutting and coagulation simultaneously during tissue resection; a dimpled vaporization roller that offers a smoother area of vaporization than a grooved roller while providing deep-tissue coagulation; a roller ball and roller barrel, which are used for coagulation and ablation of soft tissue in the bladder and prostate (the roller ball may also be used for endometrial ablation in the uterus); and a Collings knife that allows urologists access to all areas of the prostate and is most commonly used for ureteral meatotomy and transurethral incision of the prostate.

切除电极包括：手动操作、耐受高温、钨丝切除线圈；凝固穿孔前列腺切除器，比标准切除线圈的凝固面积大出40%，能够在组织切除过程中同时进行切除和凝固；一种漩涡汽化转子，比槽式转子提供更加平滑的汽化区域，同时产生深部组织凝固；一个转子球和转子滚筒，用于膀胱和前列腺软组织的凝固和汽化(转子球还可以用于子宫内膜的消融)；一个Collings刀能够帮助泌尿科医生进入前列腺的所有区域，通常用于输尿管切除术和经尿道前列腺切开。

The paper,by the theoretical analysis and calculation for the discharge time and the strike fire interval of IEC spart test device of the resistance-capacitance circuit,finds out the cause of the low sensitivity and approaches a new way to test ɑnd prove the capacitive circuit,in the prerequisite of no affect on the performances of the IEC spark test device.

目前 ，利用&IEC本安电路火花试验装置&，对时间常数较大的电容性电路试验，在多数情况下都采用拔钨丝根数来实现。

Tungsten wire is made by the process of sintered bar, swaging and drawing. Besides its high temperature stability, sagging free, shock resistance and corrosion resistance, it has an excellent electrical and thermal conductivity, a very low thermal expansion up to the highest temperature.
