An electrosurgical device is provided having at least one elastomeric seal capable of providing bio-contamination and dielectric protection by inhibiting the ingress of fluids and contaminants through the nose and actuator areas. The elastomeric seal is manufactured from a thermoplastic elastomer or resin which while in liquid form is placed within a mold. A housing section having the main circuit components and mechanisms of the electrosurgical device is then placed within the mold. Once the elastomer cures, the elastomeric seal seals the components and mechanisms within the housing partial-section. The elastomeric seal defines a flexible first opening at a distal end of the electrosurgical device to accommodate varying diameters of electrodes or blades connected to the nose area of the electrosurgical device. An actuator seal is also provided on the actuator area of the electrosurgical device to prevent fluids and contaminants from entering the electrosurgical device through the actuator area. Two buttons are insert molded within the actuator seal and are operatively associated with a self-cleaning switching mechanism within the housing section to operate the electrosurgical device between a cutting and coagulating mode.

A method of manufacturing a seal in an electrosurgical device includes placing components of the electrosurgical device within an elongated housing section, the housing section including an actuator opening, introducing the housing section within a mold filled with a liquid thermoplastic elastomer and allowing the elastomer to flow within the housing, forming an elastomeric inwardly-extending lip portion circumferentially surrounding an opening at a distal end of the electrosurgical device for introducing an electrode therein, and allowing the molded elastomer to cure and become integral with the housing to seal the components within the molded elastomer contained within the housing section. The method may also include the step of forming an elastomeric actuator seal around the actuator opening.

A cart for supporting various types of medical equipment including a main support shelf, a bottom support shelf and a pair of support legs. Each support leg having a first end attached to the main support shelf and a second end attached to the bottom shelf. The cart also including an upper support shelf which couples in spaced relation to the main support shelf. Additional support shelves can be selectively mounted and stacked atop the main support shelf in a similar fashion.
