Problems solved by technology

Another problem is that the Cobb driver does not always have a firm grip on the tissue and sometimes slips off
Also, in some applications where fixation is required, the handle can slip out of the surgeon's hand

Embodiment Construction

[0024] figure 1 It is a side view of a structure of a single-electrode electrosurgical Cobb driver tool 10 of the present invention, figure 2 is its top view. The single-electrode electrosurgical Cobb driver tool 10 includes a strip handle 12 with a size sufficient for the surgeon to hold and an internal catheter 14 for suction. A cable 16 is provided at the right end of the strip handle 12. The other end of the cable 16 is connected to a connector (not shown in the figure), which is used to connect a standard medical high-frequency generating device 18 to supply medical high-frequency current to the working end 22, and the working end 22 is a general spoon-shaped body twenty four. The cable 16 is electrically connected to the working end 22 , so the medical high-frequency current can flow to the working end 22 when the medical high-frequency generating device 18 is turned on. It is also a common method to set a dip switch (not shown in the figure) on the electric knife ha...

Abstract

An electrosurgical Cobb elevator instrument, a soft tissue dissection and / or retraction tool, can be used with and without suction, and is capable of delivering monopolar or bipolar RF energy for cutting and coagulating soft tissue. The device is capable of footswitch or handswitch activation. The tool has a spoon-shaped edge that is preferably sharp to provide blunt dissection in addition to the energy-driven dissection. The instrument of the invention could be used in any procedure that requires soft tissue dissection and / or coagulation.

Description

technical field [0001] The invention relates to electrosurgery, in particular to an improved Cobb (COBB) medical screwdriver tool which can be used as an electrode in the electrosurgical medical process that generates steam, smell or smoke. Background technique [0002] Electrosurgery has become a common treatment modality for physicians. Commercially available electrosurgical units offer electrodes in various shapes and sizes, such as needles, blades, scalpels, balls, and coils. Multifunctional electrodes are also available. Existing electrosurgical units can be connected to a medical high-frequency energy source or fitted with a hollow tube with exposed ports. By connecting one end of the hollow tube to a suction device, steam and odors generated during the procedure are removed. [0003] Cobb screwdriver tools are also known. A typical Cobb screwdriver includes a long, narrow handle with a rounded blade at the tip of the handle. The blade is used to manually remove t...
