Apex Arachnoid Knives: Designed by Neurosurgeons for Use by Neurosurgeons

Penetrator Knife

1.0 mm lancet blade with a 0.8 mm tip width

Pinpoint Precision: Permits meticulous pinpoint dissection in areas where no tension is permissible.

AM-22 8" Long Knife Handle

(Click image to enlarge) Some surgeons are comfortable holding the smooth tapered distal portion of the handle and “choking up” on the knife during surgery near the surface of the brain or operating with wrist rests. But the primary purpose of the long 4.0" tapered distal shaft is to permit precise delicate controlled microsurgery in any deep seated location.

AM-22-S 5" Superficial Knife Handle

(Click image to enlarge) The shorter handle length permits surgeons to rest their hands on the patient and maintain meticulous control at superficial depths. If a surgeon is working on a deep seated lesion, this length will be effective for opening the Sylvian or interhemispheric fissure before switching to a longer instrument.

AM-22-B Bayonet Knife Handle

(Click image to enlarge) The bayonet handle was created for the 30% of neurosurgeons who only use bayoneted instruments. While the bayonet handle provides better visibility, there is a trade-off in that the handle can’t be rotated to change the orientation of the blade as can be done with a straight instrument.

AM-22-SB 2" Short Bayonet Knife Handle
AM-22-XSB 1" Short Bayonet Knife

(Click image to enlarge) The short bayonet handles provide an instrument with facility and control for neurosurgeons operating at more superficial depths. The 1.0" and 2.0" distal shaft lengths enable surgeons to change their depth without changing their operative style or forgoing the stability gained by resting their hands on the patient. These instrument options are more effective for a large number of common cerebrovascular and skull base approaches.

AM-22-X Extended Bayonet Knife Handle

(Click image to enlarge) The extended bayonet handle with its 6.0" tapered distal shaft is intended for precise surgery in relatively inaccessible regions of the brain, where the standard bayonet would not be usable. The 0.25" diameter proximal portion of the handle is shortened from 4.0" to 3.0" to keep the overall length usable in the field and to facilitate approach to more inaccessible lesions.
