Surgical instruments and apparatus.
A collar, resting below, on the collar bones; above, supporting the base of the jaw and cranium, with hinges and screw, by which the face and head may be raised in cases of contraction; disease of the cervical vertebrae; and in wry neck; with two casts illustrating its effects.
A pair of forceps, which may be designated a bone- holder. Its use is to grasp the projecting end of any bone which it may be necessary to saw off: with this instrument a firm and steady hold can be obtained, and the bone as readily sawn through as if it were entire. It is applicable to cases of compound fracture; conical stumps or bones left too long in; common amputations; and nonunited fracture.
An improved saw, which may be advantageously substituted for the various forms of metacarpal saws, or small saws commonly in use for surgical purposes. This saw was invented by the exhibitor for the purpose of sawing through the lower jaw, parallel with and close to the base, in a case of tumour.
Model of an apparatus employed in the treatment of fractures of the thigh, with accompanying sketch, showing its use.
