SURGICAL HEADRE'ST 2 sheets-sheet 2 Filed April 5, 1962 INVENTOR CARL H. BOETCKE GEORGE T. NAGER v BY United States Patent O 3,183,079 SURGlCAL HEADRES tarl H. Boetcker, Lake Etty, la., and George l1 Nager,
Baltimore, Md., assigner-s to American Steriliaer Company, Erie, Pa., a corporation of lennsylvania Filed Apr. 5, w62, Ser. No. 185,423 ld Claims. (til. Zeil-32d) This invention relates to head-rests and, more particularly, to head holders suitable for use in combination with operating tables in modern micro-surgery of the ear and other exacting operations on the head.
A head holder to fullill the requirements of present Iday micro-:surgery of the ear has to be simple, stable, versatile, and safe as well as affording comfort to both patient and surgeon. Literature and experimentation with available head holders reveal that several prior head holders meet some of the requirements but none are entirely satisfactory.V
It is, accordingly, an object of the present invention to provide a new and improved headrest unit.
Another object of the invention is to provide an improved headrest unit which will support the head of a per* son in rigid, convenient, comfortable, versatile, and safe positions for surgery. l
Still another object of the invention is to provide an improved head holder in combination With an operating table.
A further object of the invention is to provided an improved head holder in combination with an instrument supporting device. j
'lt is a further object of the invention to provide an improved head holderin combination with an operating table and a stabilizer therefor.
Yet a further object of the invention is to provide an improved headrest for operating tables which satisiies the needs of modern :surgery and which will tit most of the operating tables now in general use.
Still a further object of the invention is to provide a head holder which is simple in construction, economical -to manufacture, and simple and eflicient to use.
With the above and other objects in View, the present invention'consists of the combination and arrangement of parts hereina-fter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from .the spirit or sacrificing any of the advantages of the invention.'
ln the drawings: Y
FlGfl is a View of an operating table with a head holder shown thereon in use with a patients head shown immobilized andthe anesthetists screen Vin position for placing drapes;
FIG. 2 is aside view of the operating table with the head holder and attaching stand for the micro-manipulator placed thereon and the telescopic stabilizing bar for the table;
FG. 3 is a top view of the head holder with the ear phone in position thereon according .to the invention;
FIG. 4 is an isometric view taken from the end of the operating table with the head holder shown thereon; and FIG. 5 is an isometric view of the undersurface of the end of the operating table showing the telescoping vertical stabilizer bar `and the method of attaching the head holder to the operating table.
Now with more specic reference to the drawings, the headrest disclosed herein is shown supported on an operating table I tiwhich may be one of the types of operating tables familiar to those skilled in the art of hopsital equipment. The table has ya hea-d portion which can be disposed in a horizontal positionV as shown in FIGS. 1 and 4 .@,ldgig Patented June 8, 1965 or it can be swung .to an inclined position. ln addition to the equipment provided with the tab-le ttl, an additional stabilizing bar indicated at 3d is shown attached tothe table to hold it positively in the position shown in FIGS. l, 2, and 4.
The headrest unit consists of three principal components:
(1) A U-shaped bar l2 which may be made of steel;
(2) A straight bar i3 which may also be made of steel;
Iand
(3) A contoured aluminum head support 118.
These three components are connected by means of ball joints having provision to lock them positively and rigidly in position and are of the type sometimes referred to as hydraulic ball joints. They are of the type shown, for example, in Patent No. 2,966,383.
The U-shaped bar l2 is disposed with its straight arms in sleeves 14 which, when on the head of the operating table, are in the back section. When in the foot end of the table, the sleeves f4 will be welded to a bar 38 on the undersurface of the foot section of the table and have set `screws MA which may be tightened to engage the legs of the 'bar i2. The sleeves la and set screws 14A constitute a lock. The arch of the U-sha'ped bar l2 has a slight bend downward which permits placing the patients head in a slightly overhanging position.
A hydraulic universal ball joint with a shell 15 is fixed to the arch of the U-shaped bar l2. This joint has a ball 81 fixed to a bracket 82 by an extension lo. A hand screw 83 can be tightened to lock the ball di in position. The bracket 32 has a bore which slidably receives the bar 13. A hand screw till may be tightened to l-ock the bar 13 against sliding in the bracket S2, A. handle 85 is used to lock a ball 26 in the manner illustrated in the said patent. The screw 84 may be loosened to adjust the straight bar 13 to any desired height.
The combination of ball joint and l-ock makes lit possible to tix the upper end of the straight bar 13 (which carries the head support) in position with it above or below the plane of the top of the table lt). The combination of the ball joint and lock further makes it possible to move the upper end of the straight bar 13 with the head support thereon toward -or away from the end of the table, to displace it sideways lfrom one corner of the table and to the other, or to move it in any intermediate oblique direction.
The ball Z6 is fixed to a base 27 4on which is contained a lock nut 19. By unscrewing the lock nut 19, the upper part of a headrest assembly 17 may be removed for cleaning. This also allows adaptation for va-rious other types of headrest having the same mounting post as at 28.
The head support The head support 13 consists of two parts; namely, the headrest assembly 17 and a rubber mattress pad 11. The metal headrest `assembly 17 is ygenerallyU-shaped with the arms and arch broad and the upper aspect concave to adapt to the contours of the lateral aspect of the skull of a human being. Thus, the head-rest assembly i7 is a trough like horseshoe form which has been found to be more desirable than a ring shaped Aform since it is designed to avoid pressure upon nerves and vessels in the neck of a person. Alt also permits good access to the undermost ear during an operation.
The sponge rubber mattress lpad 11 is detachable from the frame which supports it. The pad has a conductive rubber cover which i-s closed by Ia zipper Ztl. Conductive rubber is rubber containing an additive such as metal filings which renders it electrically conductive. T-he zipper 20 may be opened in order to change the sponge rubber pad. The zipper opening is protected from seepage by suitable flaps. Altering the amount and position of the sponge rubber inside the pad iii makes it possible to adjust the cushion to any size and configuration of skull. Generally, however, adjustment of the sponge rubber inside the pad will not be necessary.
U-shaped forks 211 are provided which have one leg lof the U fixed to the headrest assembly 17. These forks may be integral with the assembly 17 or they could be attached thereto by Welding, brazing, or the like. The forks 21 can be used to attach a head restraining strap 23 or they may be used as adhesive holders thereby to tie the pat-ients head firmly to the head support. This provides a stable adjustment of the patients head in any desired position.
At times, it may be desirable to test the cochlear funcltion during an operation under local anesthesia; for instance, during a certain stage of an operation on the oval window of the ear. Determination of the hearing acuity in the exposed ear usually requires that the opposite undermost ear be masked at appropriate lintensity levels. For this purpose, an ear phone 22 is provided which its exactly into the center of the head support 18. This ear phone can be inserted and removed lwith ease during a surgical procedure. The ear phone is best shown in FiG. 3 and iits snugly in the center of the head support.
The head support 13 may be used with advantage in connect-ion with an anesthetists screen which is shown at 40. The screen dit) will generally have a radius of act-ion of three hundred sixty degrees and be adjustable in height. It will be suitable to attach to any part of the operating table.
The table stabilizer' Absolute immobility of the headrest unit is at ali times required when, for instance, a minute manipulation is performed on an important structure of the middle ear under high magniiication or when a micro-manipulator is used during a surgical procedure. A vertical stabilizer shown in FIG. can be used in connection with the headrest unit. The stabilizer has a telescopic bar 32 which telescopically receives a bar 33. The two bars are locked together when the desired position is reached by means of a clamp screw 3d. The bar 33 has a suitable foot 3'7, Isuch as a resilient butter, made of conductive rubber on the lower end thereof for engaging a floor.
The telescopic bar 32 has a bracket 34 iixed to the upper end thereof. The bracket 34- has a slot which receives a transverse bar 38 fixed to the frame of the operating table. Clamp screws are threadably received in one leg of the U-shaped bracket 3d and clamp the stabilizing support securely to the bar 58. This simple stabilizer gives the surgeon unobstructed access to the operative site, Whether he is sitting or standing. It eliminates any movement of the operating table and headrest.
M icm-mani pulaor In the event that a micro-manipulator is used during an operative procedure to record, for instance, microphonics and action potentials from the cochlear nerve, the headrest unit is designed in such a way that a micromanipulator stand can be attachedquickly, firmly, and with ease at any phase of an operation. The stand of the micro-manipulator tits into locks 51 which are on the undersurface of the head support. Thus, the stand becomes a solid unit with the head -support 1S and, once adjusted, it can be moved together with the patients head into any desired position.
The micro-manipulator support is made up generally of a U-shaped bar 52 which has an arch 53. The U- shaped ybar 52 has legs which are slidably received in the bores in the headrest assembly 17 and are held in locked position therein by means of suitable studs 51.
A sleeve is iixed to the arch of the U-shaped bar 52. A str-aight rigid bar 54 is telescopically received in -a bore in the sleeve 55 so that the bar 54 can be slidably adjust- .able up and down therein and locked in position by a handle 56. A bracket 57 has two bores 58 and 5g disposed at ninety degrees to each other. A straight bar 6i) is slidably received in the bore S9. It may be locked in position by means of a thumb screw 61 whi-le the bar 54 is slidably received in the bore 53 and may be locked against sliding movement by means of a thumb screw 62.
A micro-manipulator bracket 71 is fixed to the distal end of the bar 6d and micrometer adjustment handles 64, 65, and 66 are fixed to the vbracket 7l. Supports 67 and 70 can be moved with precision to any desired position by manipulating the handles 64, 65, and 66. The micromanipulator Si? may be moved up and down or horizontally by adjusting the bracket 57 on the bars 54 and 6G. An ear funnel '73 can be supported on the support 67.
Summary Practically every aural surgical procedure may be performed using the 'headrest disclosed herein under general as Well as local anesthesia and on both children and adults. The unit is simple, versatile, stable, and safe, besides atording comfort for both patients and surgeons. Immobility of the operating table and patients head is required for a very delicate manipulation under high magnification of the operating microscope.
The vertical stabilizer can be attached with ease and provided with immediate immobility. Thus, the headrest unit may be used for the recording of cochlear microphonics and nerve action potentials when cochlear functions are tested at certain stages of a surgical procedure. If masking of the opposite ear is required, the ear phone can be quickly and easily attached and the head support with the inserted ear phone and its rubber cap can be used to cover and protect the undermost ear Very satisfactorily.
While the headrest unit is intended for aural surgery, it is very useful for certain neurosurgical procedures and for operations on the nose, paranasal sinuses, trachea, and larynx. It is possible to design the table and |headrest unit so that they will have a minimum elevation of, for example, twenty-seven inches which enables the surgeon to sit comfortably, experiencing minimum fatigue during long hours of minute work with the operating microscope. Only minor changes are necessary to attach the headrest unit to any operating table model. The headrest unit may be attached to either end of the usual operating tables.
