World Precision Instruments (WPI) Launches Instruments for Left-Handed People
Up to 10% of the world's population and less than 10% of the workforce in hospitals are left-handed. Surgery requires fine motor skills and a high degree of precision and expertise.
Right vs. Left-handed instruments
The construction of the right and left handed instruments have a significant impact on how they work when placed in the surgeon's hand. Whenever a left-handed surgeon uses a right-handed instrument, an unnatural position needs to be assumed which is less intuitive, inefficient for the muscle group and reduces deftness. The more precise the task, the greater is the need to tailor the instrument to the surgeon's handedness. Instruments like scissors, needle holders etc. with a ratchet action require a lateral movement. For right-handers the action is natural. The same instrument held in a left hand requires an unnatural action by the user.
Left-handed instruments in cardiac surgery
Different surgical specialties require different operative technique and skill sets. For cardiac surgery, the following are crucial:
During surgery, their hands are often located outside the cavity but the surgical instrument extends downwards into the chest. Needle control and positioning must be maintained at a distance.
For Palming proper needle holder is needed for proper operation.
Apart from surgery, the scissors and needle holders may be used by left-handed people for other applications of their choice.
