Multi-functional surgical instrument with attachable surgical instrument bits

A method of assembling a multi-functional surgical instrument, comprising:

• obtaining a handle, the handle having a bayonet holder attached to an end of the handle,
• wherein the handle and the bayonet holder are in longitudinal coordination, wherein the bayonet holder comprises a proximal end adjacent to the handle and a distal end distal from the handle;
• obtaining a surgical instrument unit, wherein the surgical instrument unit comprises an engagement unit configured to mate with the bayonet holder;
• aligning in longitudinal coordination the engagement unit of the surgical instrument unit with the distal end of the bayonet holder;
• and
• engaging the engagement unit of the surgical instrument unit with the bayonet holder,
• wherein the surgical instrument unit comprises a skin hook, a retractor, a curette, a comedone extractor, forceps, an elevator, a dissector, a bone hook, a suture remover, a punch biopsy instrument, a splinter liberator, a reflecting device, a mirror, trocars or a probe, and
• wherein the bayonet holder comprises an elevated boss in longitudinal coordination, the engagement unit comprises a keyed slot, the keyed slot comprises a top surface and a bottom surface that extend along a substantially longitudinal plane and a thickness, the elevated boss is configured to engage in an interior cavity defined by the keyed slot, the elevated boss comprises a groove that accommodates the thickness of the keyed slot, and
• wherein the keyed slot comprises a reversibly deformable material, and wherein engaging the engagement unit of the surgical instrument unit with the bayonet holder comprises:
• flexing the keyed slot to deform the longitudinal plane of the top surface and bottom surface of the keyed slot;
• thereafter placing an end of the elevated boss distal from the handle in the interior cavity of the keyed slot;
• thereafter engaging the keyed slot in the groove of the elevated boss by way of snap fit;
• thereafter sliding the handle and bayonet holder in a direction toward and end of the keyed slot distal from the handle until the elevated boss is fully inserted within the keyed slot.

A multi-function surgical instrument comprising:

• a handle, wherein the handle comprises a proximal end and a distal end;
• a bayonet holder;
• and
• a surgical instrument unit, wherein the surgical instrument unit comprises an engagement unit configured to mate with the bayonet holder,
• wherein the bayonet holder is attached to the distal end of the handle,
• wherein the handle and the bayonet holder and the attached surgical instrument unit are in longitudinal coordination,
• wherein the surgical instrument unit is releasably attached to the bayonet holder,
• wherein the surgical instrument unit further comprises a flexible neck portion disposed between the engagement unit and an end of the surgical instrument unit distal from the handle, the flexible neck portion comprises a reversibly deformable material,
• wherein the bayonet holder comprises an elevated boss, the engagement unit of the surgical instrument unit comprises a keyed slot in longitudinal coordination with a length dimension of the bayonet holder and the elevated boss, the keyed slot is configured to engage with the elevated boss, the keyed slot comprises a reversibly deformable material, and
• wherein the keyed slot is configured to be deformed so as to be snap fit into a groove on the bayonet holder thereby being coupled to the elevated boss.
