2. Description of Related Art
Known practices of cleaning a lens of a laparoscopic instrument scope involve removing the scope from the patient, wiping with a cloth, reinserting the scope, and then finding the proper location in the body again. This can occur multiple times during a procedure and increases overall procedure time as fog and/or smoke and/or bodily fluids often accumulate on the laparoscopic lens during a laparoscopic surgical procedure. Moreover, removing a device and reinserting increases infection risk, albeit a very small risk as this is performed in a sterile field. Surgeons typically must remove the laparoscope from the patient and lose time re-orienting themselves and their instruments to the operative site.
To advance the state of the art with respect to maintaining optical clarity of a surgical instrument during a surgical procedure, the present disclosure relates to a first surgical instrument having a cleaning material configured to clean a second surgical instrument. More particularly, in one embodiment, the first surgical instrument includes a handle assembly defining a proximal end of the first surgical instrument and an extension member extending distally from the handle assembly and defining a distal end of the first surgical instrument. The extension member defines an external surface. The handle assembly is configured to enable a user to move the extension member. The improvement includes a cleaning material disposed on the external surface of the extension member at the distal end. The cleaning material is configured to clean at least a portion of a second surgical instrument in proximity to the first surgical instrument. The first surgical instrument and the second surgical instrument define a distance therebetween. The cleaning material is configured to clean at least a portion of the second surgical instrument when the distance between the first surgical instrument and the second surgical instrument is reduced.
In one embodiment, the extension member is a shaft having a pair of jaw members at a distal end of the shaft. The jaw members are movable about a pivot from a first position wherein the jaw members are disposed in spaced relation relative to one another to a at least a second position wherein the jaw members are closer to one another for grasping tissue. The first surgical instrument is configured to enable a user to move the shaft and the pair of jaw members. The shaft and the jaw members each define external surfaces. The first surgical instrument includes a cleaning material disposed on the external surface of at least one jaw member or disposed on the external surface of the shaft.
The cleaning material may be disposed on the distal end of the shaft in proximity to the pair of jaw members. The second surgical instrument may be a laparoscopic instrument including a lens surface and the cleaning material is configured to clean at least a portion of the lens of the laparoscopic instrument when the distance between the first surgical instrument and the second surgical instrument is reduced.
In one embodiment, the cleaning material may be adhered to the extension member, e.g., at least one jaw member or the shaft, via an adhesive adhering a surface of the cleaning material to the external surface of the extension member, e.g., to the external surface of the at least one jaw member or to the external surface of the shaft respectively.
In one embodiment, the extension member, such as the shaft, defines a depression therein and the cleaning material is disposed in the depression in the extension member.
In yet another embodiment, the cleaning material includes a blade-like structure. The blade-like structure may be configured to clean at least a portion of the second surgical instrument when the distance between the first surgical instrument and the second surgical instrument is reduced. The blade-like structure may be formed from a flexible material. The flexible material may be made from one of cloth, rubber or silicone. In one embodiment, when the second surgical instrument is a laparoscopic instrument including a lens surface, the blade-like structure may be configured to clean at least a portion of the lens of the laparoscopic instrument when the distance between the first surgical instrument and the second surgical instrument is reduced.
In one embodiment, the extension member defines a longitudinal axis and the first surgical instrument may be configured to reciprocally move in the direction of the longitudinal axis to enable the cleaning material to clean the second surgical instrument when the distance between the first surgical instrument and the second surgical instrument is reduced.
In still another embodiment, the first surgical instrument may be configured to enable the cleaning material to move in a curved path to clean the second surgical instrument when the distance between the first surgical instrument and the second surgical instrument is reduced.
In yet another embodiment, the extension member defines a longitudinal axis and the first surgical instrument may be configured to rotate the cleaning material around the longitudinal axis to enable the cleaning material to clean the second surgical instrument when the distance between the first surgical instrument and the second surgical instrument is reduced.
The present disclosure relates also to a method of cleaning at least a portion of a second surgical instrument in proximity to a first surgical instrument. In one embodiment, the first surgical instrument includes a handle assembly and an extension member that extends distally from the handle assembly. The method includes disposing a cleaning material on an external surface of the extension member; positioning the first surgical instrument in proximity to a second surgical instrument to define a distance between the first and second surgical instruments; reducing the distance between the first surgical instrument and the second surgical instrument; and cleaning at least a portion of the second surgical instrument with the cleaning material when the distance between the first surgical instrument and the second surgical instrument is reduced.

The embodiments of the present disclosure relate to a surgical instrument having a cleaning material that is disposed on a shaft or on a jaw member of a first surgical instrument in which the cleaning material is configured to clean at least a portion of at least a second surgical instrument in proximity to the first surgical instrument. The embodiments of the present disclosure advance the state of the art of surgical procedures by speeding procedure time, by requiring fewer steps for cleaning, and by lowering the risk of infection.
The surgical instrument having a cleaning material according to the embodiments of the present disclosure eliminates time costly steps by incorporating a laparoscopic wipe feature on the shaft of a commonly used laparoscopic surgical instrument such as a radio frequency (RF) sealer/divider, manufactured by Covidien, Inc (Boulder, Colo., USA) under the trademark LIGASURE™ or an ultrasonic dissector, manufactured by Covidien, Inc. (Boulder, Colo., USA) under the trademark SONICISION™.
The cleaning material or wipe may be made from a material that is felt-like and adhered to the shaft of the device near the jaws. Other material options include rubbers/silicones that behave similarly to windshield wipers.

In conjunction with
At least a second exemplary surgical instrument 200 includes a shaft 202 having a distal end 202a and a proximal end 202b. The distal end 202a of the shaft 202 is disposed through a second trocar 240 that penetrates a second incision IN2 into the abdominal cavity AC of the patient P. The second surgical instrument 200 may be inserted through the second trocar 240 via a movable handle (not shown) that may be disposed in the vicinity of the proximal end 202b of the shaft 202. The first surgical instrument 100 and the second surgical instrument 200 are positioned through the first and second incisions IN1 and IN2 at an angle with respect to each other to define a variable distance D1 between the distal end 102a of the first surgical instrument 100 and the distal end 202a of the second surgical instrument 200.
