ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of surgical implements in general, and in particular to a surgical scalpel which is provided with a manually actuated syringe feature.
2. Description of Related Art
As can be seen by reference to the following U.S. Pat. Nos. 2,656,600; 3,990,453; 4,642,090; 5,088,198; and 5,161,308, the prior art is replete with myriad and diverse combined devices used for a variety of tasks.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical device for providing a manually controlled flow of liquid such as distilled water or medicinal fluid to an incision site.
As most surgeons are aware, there are certain instances during surgical procedures wherein it is desirable to introduce liquid into a incision site to either flush the opening of debris or to directly apply a dose of liquified medicine at the incision site, and to prevent the development of surgical wound infections which are considered to be the second most common hospital acquired infections which contribute significantly to morbidity and mortality, as well as excess costs for hospitalized patients.
As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved hand held surgical implement that combines a syringe or quasi-syringe with a scalpel blade, and the provision of such a construction is a stated objective of the present invention.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the combined scalpel and syringe device that forms the basis of the present invention comprises in general, a handle unit, a scalpel unit, and a syringe unit wherein at least a portion of the syringe unit is contained within the handle unit.
As will be explained in greater detail further on in the specification, the handle unit includes a generally hollow cylindrical handle member having an open end and a substantially closed end provided with a discrete aperture.
The scalpel unit includes a scalpel blade member fixedly secured to the substantially closed end of the handle member such that the handle member can be manipulated in the normal fashion to function as a scalpel device.
In addition, in the preferred embodiment of the invention, the syringe unit comprises a syringe needle member operatively connected to the discrete aperture in the substantially closed end of the handle member and a plunger member slidably disposed within the hollow handle member to force fluid from the handle member through the syringe member. The syringe member is aligned parallel to the upper flat edge of the scalpel member.
