Embodiment Construction

[0029] In FIG. 1 a scalpel 101 is inserted with a scalpel handle extending outwardly from an inlet location receptacle 102 . The inlet positioning socket 102 only allows it to be inserted in a certain orientation, whereby the gripping fingers 104, 105 of the scalpel 101 only open or close in the horizontal direction. The entry positioning receptacle 102 also defines the insertion depth of the scalpel, whereby once the clamping fingers 104, 105 are opened, the used blunt blade 106 falls precisely into the sharps container 107 mounted below it.

[0030] Such as figure 2 As shown in , the gripping fingers 104 and 105 can be opened or closed by moving two arms 108, 109 attached to each gripping finger. The arms 108 , 109 are constrained to move only in the slot 114 . Movement of the arms 108 , 109 is controlled by twisting the scalpel handle 111 relative to the scalpel holder 110 . The internal mechanism of the scalpel 101 will be described in detail below with reference to FIG...

Abstract

A modified scalpel and blade exchanging apparatus and method whereby insertion of the scalpel blade(106)end into the apparatus and turning of the scalpel handle(111)causes the dull or spent blade to be exchanged with a new blade(130)on the scalpel(101)in a few seconds. The quick exchange is accomplished by a cam system(183, 184)that opens and closes the jaws or fingers(104, 105)that retain the blade on the scalpel and a dispenser(119)that positions the new blade in the open jaws or fingers just prior to closure. The new invention solves the problem of detaching and attaching scalpel blades in a matter of seconds without danger to the user. With a mere twist of the wrist, the user detaches the dull blade and attaches the new blade, the dull blade dropping into a sharps container(107)upon detachment. Also, by the design of the apparatus, contact of the dull contaminated blade with the apparatus is substantially eliminated with the exception of a protective cap(102A), protective ring(340)or disposable socket(102)that are removable for separate sterilization or disposal. In the preferred embodiments, the new blades are dispensed from a cartridge(119)and multiple cartridges may be provided for the selection of differing blades.

Description

technical field [0001] The field of the invention relates to medical scalpels, and more particularly to methods and apparatus for safely replacing scalpel blades. Background technique [0002] A typical medical scalpel is very sharp and securely held in the scalpel handle. Even after dulling with continued use, the blade is still very sharp, so it is dangerous to manually remove it from the scalpel handle in order to change the blade. In addition, especially in pathology laboratories, blunt scalpels can be contaminated with many unknown and very dangerous germs, such as hepatitis species. Immunodeficiency virus (HIV) and tetanus. [0003] Scalpels are widely used in hospitals, laboratories and various industrial sectors. In conventional use, a scalpel is discarded after multiple uses and a new scalpel is attached to the scalpel handle. Manually removing a blunt blade from a scalpel handle is fraught with hazards due to the potential for contamination by germs. US Patent...
