SURGICAL ARM CHAIR. I
Application fi1ed Februar 8, 1927, Serial No. 166,750, and in Argentina a ri1f14," 926.1
The present invention relates to a surgical arm-chair adapted to facilitate operations to the head, upper limbs and thorax and, for that purpose, capable of holding the patient n any of the positions most favourable for this kindof operations.
' I To that effect, the invention is'characterized V by the combination, with an axial rod'carryinga seat andthe height of whichis adjustable relatively to a pedestah'of radial arms* capable both of pivoting aboutthe said axial rod, of moving along the latterand to lock 1n the chosen position, one of these radial arms carrying foot-rests which can be orientated about an are, preferably horizontal, and the other, connected rods orientable about an axis,
preferably horizontal, and serving as slides "serving also as'supports for a back and a head-rest adjustable in position.
- The accompanying drawing illustratesfloy' way of example only, a formof construction of a surgical arm-chairor vertical surgical table such as above outlined. v

Fig.'6 shows the'arm-chair in position for i an operation on the, lateral region of the thorax."
Fig. 7 is a perspective view, showing the' arm-chair in position for an operation on the lateral region of the face,
The arm-chair comprlses a supporting ped-" estal, preferably of. cast-iron, of the type gen erally employed in dentist arm-chairs, consist ing of a central part 1 and feet '2' resting on the ground. vOne of said feet 2 I at least is provided with a'screw 3 the point of which is adapted to slightly enter into the, floor of the operating room for ensuring the adherence of.
the arm-chair thereto.
In an axial bore of the central part 1 is fit-r ,ted a hollow rod l-provided with an'operat ing han'd-wl'leel 5 and immobilized in theaxial direction in any suitable manner. Into said rod 4 is screwed a screw-threaded rod 6 which screw 12.

V e p The parts25 of: the uprights. 19 serve as supports for radial arms 26;passing through heih e sockets'27' of parts 19; Said socketsare ro:
-vided witlilo'cking screws 28 which: permit adjusting of their "height along the upright and their angular orientation ther'eabout;
flhef-arm's. serve as supports ffor rods 29 v of' channelmembers 30 forming arm-rests. Theconnection between the arms 26 and the rods 29 is preferably effected through the medium of a .double joint 30*, of well known construct-ion, which permit the rod 29 to pivot about and slide along the longitudinal axis thereof; and rod 29 and joint 30 to pivot and slide relatively to the arms 26. A locking screw 31permits locking of the joint 30 and the rod 29 in the respective positions chosen. V
The arm-rests 30 are, for instance, made of pressedsheet-iron, and secured to the rod 29 provided with lugsl32 at its upper part.
vThe arm-rests .30 are preferably internally lined witha quilted packing of any suitable nature and-arrangement; and are provided with straps 33 permitting to immobilizethe I fore-arms ofthe patient. 7
The arms 26 are normally arranged on the uprights '19, above the cross-member 20 which supports 13 on the arm 7 ;The lower branch 14. might even be pivoted, for instance by forms the back, but since cross member 20 is i simply traversed atits ends by the upper up rights 25 and provided with looking screws 20, it may be removed so as to permit of mounting the arms 26 on the rods 25, if necessary, for causing the patient to occupy a predetermined position Y V j The arm-chair just described is susceptible tomodification. The cross-member 18 might, a for instance, be jointed along the theoretical Q Xis thereof. This would give to the arms 19 a greater freedom and would allow them to occupy any position in space. The same arrangement might be applied for fitting the meansof a ball and socket oint, on the upper branch 13 of. the supports of the foot-rests, so as to give to these supports any desired position. l

The arm rests 30 are placed in the positions shown, and the patient lays the side of his head, which is not to be operated, on the head-rest 21.
The advantages of the surgical arm-chair 'orvertical surgical table which has just been described, result "from the fact, sanctioned by experience, that the most favourable position for operating on a patient on the head, the thorax or the upper limbs, is preferably a. seated position with proper inclination.
