Abstract
Bipolar electrosurgical forceps are provided with dual irrigating tubes that deliver irrigating liquid to the opposed surfaces of the tips of the forceps to prevent the sticking of body tissue to the tips. To reduce the manufacturing costs of the forceps and enable the forceps to be single use, disposable forceps, each tube of the dual irrigating tools is a plastic tube adhered along one of the opposing surfaces of the pair of forceps arms. Each tube also has a flat nozzle at the distal end of the tube that disburses irrigating liquid across the opposed surfaces of the forceps arm distal and tips.
Claims20
A forceps comprising:
- first and second arms, each of the first and second arms having an elongate length with opposite proximal and distal ends and having opposite inner and outer surfaces that extend the elongate length of each of the first and second arms, the proximal ends of the first and second arms being connected together with the inner surfaces of the first and second arms opposing each other, and the distal ends of the first and second arms being constructed as tissue cauterizing tips;
- and
- a first irrigation tube having a length with opposite proximal and distal ends, at least a part of the first irrigation tube length being secured to the first arm with the first irrigation tube length extending from the first irrigation tube proximal end adjacent the first arm proximal end, across the elongate length of the first arm to the first irrigation tube distal end adjacent the first arm distal end, the first irrigation tube having a cross-section configuration along its length, wherein the cross-section configuration is a substantially circular configuration as the first irrigation tube extends from the first irrigation tube proximal end toward the first irrigation tube distal end and wherein the cross-section configuration changes from the substantially circular configuration to an oblong configuration at a portion of the first irrigation tube length adjacent the first irrigation tube distal end with the cross-section configuration of the first irrigation tube distal end being oblong.
A forceps comprising:

- and
- first and second plastic irrigation tubes, each of the first and second plastic irrigation tubes having a length with opposite proximal and distal ends, at least a part of the first plastic irrigation tube length being secured to the first arm with the first plastic irrigation tube length extending from the first plastic irrigation tube proximal end adjacent the first arm proximal end, across the elongate length of the first arm to the first plastic irrigation tube distal end adjacent the first arm distal end, the first plastic irrigation tube having a cross-section configuration along its length, wherein the cross-section configuration of the first plastic irrigation tube is a substantially circular configuration as the first plastic irrigation tube extends from the first plastic irrigation tube proximal end toward the first plastic irrigation tube distal end and wherein the cross-section configuration of the first plastic irrigation tube changes from the substantially circular configuration to an oblong configuration at a portion of the first plastic irrigation tube length adjacent the first plastic irrigation tube distal end with the cross-section configuration of the first plastic irrigation tube distal end being oblong, and at least a part of the second plastic irrigation tube length being secured to the second arm with the second plastic irrigation tube length extending from the second plastic irrigation tube proximal end adjacent the second arm proximal end, across the elongate length of the second arm to the second plastic irrigation tube distal end adjacent the second arm distal end.
