Abstract

Embodiments of the invention are directed to a medical device with a handpiece that provides enhanced comfort of use, maneuverability, and for a variety of hand-held options to the user. Embodiments of the invention include handpieces that include a grip panel comprised of a friction-enhancing material to facilitate gripping of the handpiece by an operator. In addition, embodiments of the invention include handpieces having a generally symmetrical configuration in order to facilitate grasping by an operator'"'"'s left or right hand.

Claims

1. A method for operating a medical device to perform a medical procedure, comprising:

providing a medical device comprising;

a medical instrument connected to a front end of a handpiece, the handpiece including an attachment structure along a front end thereof configured for removably coupling to the medical instrument, the handpiece further comprising a housing, the housing comprising;

a top surface defining at least one hole for receiving at least one button for controlling a function of the medical device;

a bottom base; and

an extension portion connected to the base and extending downwardly therefrom, the extension portion including a shoulder connected to the base by a narrowed neck portion located between the shoulder and the top surface of the housing, an outer circumference of the narrowed neck portion being smaller than an outer circumference of the shoulder, the shoulder having an underside surface having a generally concave shaped, curved surface;

wherein the base, the shoulder, and the narrowed neck portion define a concave shaped surface capable of receiving an operator'"'"'s finger;

grasping the handpiece with one of a left hand or a right hand such that the operator'"'"'s thumb rests over the control button, and an operator'"'"'s finger rests on the concave shaped surface, the handpiece capable of being grasped by the left hand or the right hand in the same manner;

positioning the medical instrument; and

actuating the control button to perform a medical procedure.

2. The method of claim 1, wherein actuating the control button comprises one of supplying suction or irrigation to the medical instrument.

3. The method of claim 1, wherein actuating the control button comprises providing electric current to the medical instrument.

4. The method of claim 1, wherein a proximal portion of the medical instrument includes a rotatable element configured to control the angular orientation of the medical instrument, the method further comprising rotating the rotatable element with a finger of the same hand used to grasp the handpiece in order to change the angular orientation of the medical instrument relative to the handpiece.

5. The method of claim 1, wherein grasping the handpiece comprises receiving the concave shaped, curved surface of the shoulder within an operator'"'"'s palm within a valley between an operator'"'"'s thumb and index finger.
