Abstract

In operation of the apparatus of the preferred embodiment, a used surgical sharp is placed into a drop window or receiving opening. Once the sharp is resting upon the partial floor of the housing assembly, the user will engage a safety slide having a pinch style cutter mechanism, so that a mandrel and blade converge and shear any remaining suture material from a needle. This also closes a window protector over the receiving opening. A magnet properly aligns metal items for disposal. Once any suture material is cut from the needle, a safety device consisting of opposing intermeshable rakes sweeps the sharp along the partial floor and into the drop window. This sweeping motion is created by the user moving the shuttle assembly from front to rear from a first to a second position. The shuttle assembly must be moved to the second position before it can be returned to the first position. A counter is then engaged to advance one increment. The safety rake system assures that the counter is advanced if and only if a sharp is introduced and cycled through the apparatus. If no sharp is between the two rakes to present an obstruction between the rakes, the tines of the rakes will intermesh and the counter will not be advanced. The sharp falls through the drop window and into the drop area of a disposable receptacle. Combs ensure the sharp doesn'"'"'t "stick" to the rake tines. The sharp count is accumulated numerically by the mechanical counter.

said housing assembly having a front and a rear;

said counter having engagement means to advance counter to the next number; and

,

b. a movable shuttle assembly slidably received in and retained by said housing assembly, said shuttle assembly having a receiving opening therein, such that any item received into said receiving opening will be received on said partial floor of said housing assembly, whereby, when said shuttle assembly is slidably moved from a first position to a second position, any item on said partial floor is deposited in said removable receptacle and said counter advancer means is engaged to advance said counter to the next number.

2. The apparatus of claim 1, wherein said housing assembly further comprises:

means to reset said counter when said removable receptacle is included into said housing assembly.

4. The apparatus of claim 1, further comprising:

means to position said movable shuttle assembly at said first position and necessitate that when said shuttle assembly is slidably moved, said movable shuttle assembly must be moved to said second position before said movable shuttle assembly can be returned to said first position.

5. The apparatus of claim 4, wherein said shuttle position means comprises:

a. a force having an opening therethrough, said opening in alignment with said receiving opening in said shuttle assembly;

said force attached to said shuttle assembly and forming a part thereof;

said force having a bottom surface, said bottom surface having a pair of downwardly-extending, rectangular-shaped, front force rails, said front force rails being in a parallel alignment;

whereby, when an item to be disposed is deposited into said receiving opening and received on said partial floor of said housing assembly and when said shuttle assembly is slidably moved from said first position to said second position, said item prevents said front rake tines from intermeshing with said rear rake tines, thereby causing said actuator-engaging rib to move toward said rear of said housing assembly engaging said front tip of said actuator thereby causing said rear tip of said actuator to move against said actuator spring toward said rear of said housing assembly and engage said counter advancer means to advance said counter to the next number, said item being deposited into said removable receptacle;

but, if no item is present and said shuttle assembly is slidably moved from said first position to said second position, said front rake tines and said rear rake tines intermesh and said actuator-engaging rib does not cause said rear tip of said actuator to engage said counter advancer means.

8. The apparatus of claim 7, further comprising:

whereby, when said shuttle assembly is at said first position said front rake tines and said front comb tines are in alignment relative to said front force rails and said rear rake tines and said rear comb tines are in alignment relative to said rear force rail;

as said shuttle assembly is slidably moved from said first position toward said second position, said rear force rail in said rear comb rail receptacle causes said rear comb to initially slide toward said rear of said housing assembly before said rear rake, thereby non-aligning said rear rake tines and said rear comb tines, and said protruding rail and said pair of front force rails in said front comb rail receptacle cause said front rake to initially slide toward said rear of said housing assembly before said front comb, thereby non-aligning said front rake tines and said front comb tines; and

these non-aligned tine positions are maintained until said shuttle assembly reaches said second position; and

, as said shuttle assembly is slidably returned from said second position toward said first position, said rear force rail in said rear comb rail receptacle causes said rear comb to initially slide toward said front of said housing assembly before said rear rake, thereby realigning said rear rake tines and said rear comb tines and combing any item from said rear rake tines, and said protruding rail and said pair of front force rails in said front comb receptacle allow said front rake to initially slide toward said front of said housing assembly before said front comb, thereby realigning said front rake tines and said front comb tines and combing any item from said front rake tines.
