Addressing Challenges in Tumor Removal with Innovative Design
Designed to reduce costs, be used in combination with other available surgical equipment, and overcome drawbacks of known instruments in use. This scissors helps in endoscopy surgery to remove small visible tumours from the bladder for improved cancer diagnosis and research. The following lists some of its innovative improvements.
Fluid Injection
- The surgical instrument consists of a extendable scissors-needle combination with a pair of blades and a needle spaced away from the scissors configured to inject a fluid.
- With markings on the needle, the scissors allows for precise insertion of the needle and fluid injection.
Improved Blades
- Inner sharp edges of blades made of conducting material and the outer blunt edges made of non-conducting material. This allows the scissors to be configured for being coupled to a source of high frequency electric current, wherein the high frequency electric current is configured to coagulate to control bleeding.
Manipulation
- Precisely rotate the shaft about the longitudinal axis of the shaft to enable orienting the scissors in a desired orientation.
- Extend the needle using a small lever placed on the handle or retract it when not needed.
