Instrument for guiding the surgical cutting of tissue and method of use

An instrument is provided for cutting tissue having a housing, a shaft extending from the housing to a distal end with an opening, and a guide tube extending from the distal end through the opening for receiving a guide wire through the shaft and housing. A movable blade shuttle having a blade is provided at the distal end. The blade shuttle's travel is guided by the guide tube when the blade shuttle and blade is extended from the distal end opening to cut tissue and retracted back through the distal end opening. The housing has a pivotal actuator member mechanically coupled to the blade shuttle to remotely control movement of the blade shuttle at the instrument's distal end. The instrument may be used for longitudinal cutting of tissue at remote sites in the body of a patient to provide incisions of precise depth and length over a controlled path of a guide wire.

Multi-bladed surgical scalpel

This multi-bladed scalpel addresses the problem of making many small incisions in very close proximity to each other, to facilitate hair transplantation. With this device, it is possible to make multiple incisions in such proximity. With the blades mounted parallel to each other, at the desired spacing, each incision does not intersect neighboring incisions, so the follicles placed in each incision will be surrounded by the maximum amount of undisturbed tissue to promote revascularization—capillary growth to provide a blood supply to each transplanted follicle. CNC machining techniques are used to create the blade holders with blade mounting sites created at the desired proximity. Medical grade epoxy is used to mount the blades, which are mounted parallel to each other. Blade mounting holes are drilled so the tips of the blade group form a planar array of interdigitated and offset blades at an angle with respect to the handle.
