Description

MAURICE JULLIARD M. JULLIARD sept. 23, 1958 SYRINGES v Filed Oct. 4, 1956 United States Patent() SYRINGES Maurice Julliard, Paris, France Application October 4, 1956, Serial No. 613,957

7 Claims. (Cl. 12S-218) This invention relates to hypodermic syringes and smilar surgical instruments for injecting liquids and it has for its primary object to provide a syringe which .can be manipulated with great precision and with little eiort, the movements of the parts of the syringe and especially the advance of the piston, and the direction of advance of the injection needle being iinely regulable to an extent which hitherto rhas not been obtainable.

A principal object ofthe invention consists in providing a syringe with a piston the movement of which in both directions is not produced by the operator ofthe syringe, but is mechanically produced and'is derived from a rotary movement transmitted from an external source of such movement.

Another principal object of the invention consists in providing an injection needle arrangement permitting adjustment of the angular position `of theinjection needle relatively to the body of the syringe and relatively tothe direction of the piston movement therein, said arrangementalso including a resilient connection between the injection needle and the syringe body which simultaneously also acts as a seal of the syringe after adjustment of the needle.

Further objects of the invention and further characteristics of the same will be apparent from the following` detailed specification.

The invention is illustrated in the accompanying drawing by way of example. It is however to be understood that the embodiment of the invention which has been illustrated by wayV of example has been selected with a view of explaining the principle of the invention and the best mode of applying said principle. Other applications of the same principle will readily occur to theexpert in this field when following the directions contained in the following specification.

In the drawing:

Fig. 1 is an elevational view in longitudinal section of a syringe according to the invention.

Fig. 2 is an elevational cross sectional view of the syringe illustrated in Fig. 1, the section being taken along line II-II of Fig. l. Y

Fig. 3 is an elevational .cross sectional view, the section being taken along line III-III of Fig. 1.

As seen in the drawing the body 1 of a hypodermic syringe is provided with a bore in which the piston 2 reciprocates, which piston may or may not be provided With sealing means, such as the piston rings 3. Near the injection needle carrying end the body 1 is provided with a threaded portion, the threads of which are engaged by a retaining sleeve 4 eng-aging and holding, by means of an inwardly projecting flange, the outwardly projecting flange of a cap 5 with a semi-spherical end portion. The

cap tits tightly over the end portion 9 of the body 1. The

semi-spherical end portion of the cap is provided with a slot 6. It forms the seat of a spherical injection needle holder 7 which is preferably made of a resilient or elastic material, such as synthetic rubber or a polyethylene plasice tic. This ball shaped needle holder is provided with a diametrical bore through which the injection needle passes and in which it is rmly held.

When the needle is in operative position the end 9 of the syringe body is pressed firmly against the needle holder 7 by the retaining sleeve 4, holding the needle holder and the injection needle in the desired angular position, the resilient needle holder forming a sealing element, sealing the bore of the syringe body.

It will be understood that this injection needle carrying arrangement permits orientation of the injection needle in any desired direction over a wide angle, by turning the injection needle within the slot and by turning the body of the syringe around its axis. To produce the angular adjustment of the needle it is only necessary to loosen or to unscrew the retaining sleeve 4, thus relieving the pressure on the ball shaped needle holder 7, which may then be turned in the desired direction. When the retaining sleeve, after adjustment of the needle is again tightened the elastic ball shaped needle holder 7 is rmly applied against the end 9 and seals the end of the bore, of the syringe body, all parts being again rmly held in their selected position.

The other end of the body may be provided with an enlargement of hexagonal cross section (Fig. 3) or any other cross section permitting a irrn grip, said enlargement having internal threads which engage corresponding threads provided on a sleeve like projection from a gear housing 10. The said sleeve may hold a key member 11 which projects inwardly and which engages a longitudinal groove of a spindle carrying the piston 2. The spindle is of the type generally used for lead screws and is provided with helical square threads extending over a suitable length, which length depends on the stroke of the piston and on the length of the gear case 10. On both sides of the threaded portion of the spindle a portion of the spindle 13, 14 respectively, of reduced diameter is provided. The end of the spindle carries a knob 15 which permits m-anual operation of the piston in the conventional manner.

The gear case 10 houses an essentially cylindrical shaftxlike rotary member 16 which is provided with an internal bore of a diameter which is substantially equal to the outer diameter of the threads of the spindle 12. This member is integral with or txedly carries a worm wheel 17. The gear case further houses a worm 1S meshing with the work wheel 17. The worm is mounted on a shaft 19 which projects outwardly (Fig. 2) and which is provided with means for coupling it `with the flexible shaft which is driven by an external source of regulable rotary motion, for instance from the turret or equipment stand `such as used in connection with a dentists chair with which the exible shaft may be connected. With such an equipment the speed of rotation of the drive means of the lexible shaft is nely adjustable by means of a footpedal which regulates the driving motor of the turret or stand. f

The rotary member 16 carries a drive piece in the shape of a half-nut 21 with internal threads engaging the helical square threads of the spindle 12. rl`his drive piece may be mounted on a small longitudinal spindle within a suitable cut-out portion of the member 16.

The spindle 20 around which the drive piece 21 in the shape of a half-nut may be rocked is preferably in an eccentric position relatively to the axis of the half-nut and spindle, as seen in Fig. 2, so that the half-nut may be swung out of engagement with the threads of the spindle 12. When out of engagement with the half-nut the spindle may be manipulated in the .conventional manner by forcing the piston down manually towards the needle 3 carrying end of the body 1, by application of pressure on the knob 15.

When the driving half-nut 21 is in engagement with the threads of the spindle 12, it advances the spindle by its rotation with the member 16 which is journaled within the gear case in suitable bearings. As shown the front bearing may be a removable member fixed on the gear case by means of screws, to permit insertion and withdrawal of the member 16. The spindle 12 will be held against rotation by the key member 11 which is held in its position by the gear case or which is merely a part of the gear case.

It will be clear that when during rotation of the spindle one of the portions with reduced diameter ismoved under the half-nut any further movement of the spindle 12 and of the piston is automatically stopped.

If the speed of rotation of the work 18 .and shaft 19 can be controlled, it is possible to regulate and control nely and precisely in any desired moment the speed with which the liquid is injected. The control of this speed by variable pressure on knob 15 becomes unnecessary and the operator of the syringe is relieved of the task to pay constant attention to the pressure which he has to exert on the knob. Further, the use of the syringe is greatly simplied and improved by the angular adjustment of the position of the injection needle. In many cases the position of the instrument is prescribed by the available space or by the relative position of the patient and the operator, but does not coincide with the direction in which the needle should penetrate or the liquid should be injected by the resilient needle carrier which permits a very line and precise adjustment and orientation of the needle relatively to the direction of the piston advance. This disadvantage is completely eliminated.

It is of special importance that a completely regular and gradual movement of the injection needle and discharge of the liquid injected through the needle occurs, as this reduces greatly or eliminates the pain caused by the injection and especially that produced by the sudden piercing of the tissues.

It will be clear that changes of an unessential nature may be made without departing from the essence of the invention as defined in the annexed claims.
