Definitions
- This invention relates generally to surgical instruments, and more particularly to low-profile instruments and operational techniques, the instruments having a central working channel for receiving other instruments such as a video endoscope.
- One of the objects of the present invention is to provide new and improved assemblies of surgical instruments for use in minimally invasive surgical procedures, particularly those procedures where it is advantageous to have a single entry portal for the instrumentation and the vision system. It is another object of the present invention to provide very low profile surgical instruments optimized for use in confined spaces.
- At least two of the tubular members are movable relative to each other, and one or both of the two has an end effector at its distal end, the end effector being a functional device that can be actuated to perform a function such as cutting, clamping, abrading, or any other corrective, therapeutic, or manipulative action at the distal end of the instrument.
- actuation of the end effector(s) is achieved by moving one of the two or more tubular members relative to the other. This results in either the individual action of a single end effector or the coaction of two end effectors.
- various types of action and directions of movement can be achieved by appropriate construction and joinder of the parts.

- a second pin which may mate with the actuating slot on the blade.
- a preferred embodiment of a handle of the present invention may consist of a pistol grip.
- the grip may be made in two halves, each molded from a thermoplastic such as ABS.
- the halves may be configured to receive the coaxial tubes which comprise the tips of the disclosed invention.
- the grip may also contain a trigger, simil.arly molded of ABS plastic, which rotates about a pivot within the grip.
- the trigger may also be attached to a linkage which converts the rotary motion of the trigger to relative linear motion of the coaxial tubes.
- the linkage may further have fitted a spring which may predispose the linkage to reside at a neutral position or perhaps a position at one extreme of the linkage's full travel.
- the grip may have a lock which engages the linkage thereby preventing motion of the tubes.
- This lock may engage the linkage at any of several positions.
- the grip may have an additional locking nut on the proximal end of the grip, aligned with coaxial tubes. This nut may be configured to constrict its ID .and thus secure items placed into the coaxial tubes.
- a flexible endoscope such as those available from Claras Medical Systems, Inc., may be secured to the grip with the locking nut. Use of the flexible endoscope allows the weight and bulk of the endoscopic camera and light cable to be located distant from the grip thus enhancing the maneuverability of the grip.
- a handle of the present invention may consist of a screw driver type grip.
- the grip may be made in two halves, each molded from a thermoplastic such as polycarbonate.
- the halves may be configured to receive the coaxial tubes which comprise the tips of the disclosed invention.
- the grip may also contain an actuating trigger, similarly molded of polycarbonate plastic, which slides within a slot within the grip.
- the trigger may also be attached to a linkage which converts the linear motion of the trigger to relative rotary motion of the coaxial tubes.
- the linkage may further have fitted a spring which may predispose the linkage to reside at a neutral position or perhaps a position at one extreme of the linkage's full travel.
- the grip may also have a lock which engages the linkage thereby preventing motion of the tubes. This lock may engage the linkage at any of several positions.
- the grip may have an additional locking nut on the proximal end of the grip, aligned with coaxial tubes. This nut may be configured to constrict its ID and thus secure items placed into the coaxial tubes.
- an endoscope such as the MINI-SITE referred to above may be secured to the grip with the locking nut.
- a further embodiment of a handle of the present invention may consist of a pistol grip.
- the grip may be made in two halves, each molded from a thermoplastic such as ABS.
- the halves may be configured to receive the coaxial tubes which comprise the tips of the disclosed invention.
- the grip may also contain a DC motor such as that available from Micro Mo Electronics, Inc., Clearwater, Florida, USA.
- the motor may also be attached to a linkage which translates the rotary motion of the motor to relative motion of the coaxial tubes, the relative motion being either axial, rotational, or oscillatory either in the axial or rotational directions.
- the motor may be connected to a speed control, such as a potentiometer, within the grip.
- the potentiometer may be accessible to the operator, thereby .allowing speed control of the motor.
- the speed control may also be connected to a commercially available DC power source, external to the grip.
- the grip may also have a locking nut on the proximo end of the grip, aligned with coaxial tubes. This nut may be configured to constrict its ID and thus secure items placed into the coaxial tubes.
- a flexible endoscope such as those available from Claras Medical Systems, Inc., may be secured to the grip with the locking nut. Use of the flexible endoscope allows the weight and bulk of the endoscopic camera and light cable to be located distant from the grip thus enhancing the maneuverability of the grip.
- the endoscopic camera may also be connected to a video imaging system.
- the video imaging system may contain image stabilization means to prevent the endoscopic image from becoming blurred as a result of the action of the motor.
- two or more surgical instruments in accordance with the invention can be used simultaneously, each with an endoscope passing through its lumen. Images from the two endoscopes can be viewed simultaneously on two or more monitors or on a single monitor with a video image splitter.
- Imaging devices are but one example of such secondary instruments.
- Other ex.amples are needles, or the use of the lumen to provide aspiration, irrigation, or both. Aspiration and/or irrigation may be achieved by the use of media such as a gas or a liquid.
- the lumen can also be used as a channel to remove material from the surgical site surrounding the distal end of the tubul.ar members.
- the imaging device inserted through the lumen can be an optical fiber, an endoscope or any other type of imaging component among those known in the art. Endoscopes may range in diameter from about 0.5 to about 10 mm.
- an image stabilization component is preferably included as well. Such components are well known to those skilled in the construction and/or use of endoscopes.
