OBSTETRICAL INSTRUMENT.
Application filed February My invention relates to obstetrical devices and more particularly to improvements in my prior Patent 1,614,67 9, January 18, 1927.
lVith the device disclosed in the above identified patent, it is necessary to exert strain upon the gripping tapes with one hand While the separable handle members are held in the other hand. It is therefore an object of this invention to provide an obstetrical device which, after being adjusted to the infants head, may be manipulated with one hand to draw the infant from its mother.
Further the invention provides an obstetrical device embodying a pair of separable handle members and a flexible loop which is adjustable relative. to the handle members so as to be correctly positioned about the object and subsequently maintained undertension incident to the outward pull on the handle members. a
The invention also provides an obstetrical instrument having a slidable finger engaging 1 element to which the ends of the loop are attached so that the loop may be tensioned about the object and maintained in this condition by sliding the finger engaging element relative tothe handle members.
, lVith the preceding andother objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangement. of parts to be hereinafter specifically referred to, claimed and illustrated in the accompanying drawings, wherein:
Figure 1 is a perspective of the invention in operative position;
Figure 2 is a top plan view a V embracing loop removed;
Figure 3 is a perspective of one of the handle members being placed in operative position' Figure/1 is a transverse section taken on line 4.4 of Figure 2';
Figure 5 is a similar view taken on 5-5 of Figure 1; and 7 Figure 6 is a fragmentary perspective of a modification of the invention.
Referring to the invention in detail aopair of separable parallel handle members 5 and 6, having oppositely curved arms 7 formed at one end and terminating in eyes 8, is provided. hen in operative positionvthe handle members are arranged with the arms 7 in opposed relation and the eyes in transverse alinement. In practice the handle members will be conwith the head line 3,1928. Serial No. 251,676.
.structed'from metalhaving a slight resiliency erators hand during the extraction or pulling I opera ion. A rectangular opening 10 is pro vided in the inner face of the spherical ele ment 9 for the reception of the adjacent end of the handle member 6, as illustrated in Figure 2.
In order to grip the infants head, a flexible adjustable loop 11 is provided and cooperates with the handle members. The loop is formed from textile tapes 12 arranged in superimposed relation with their longitudinal edges stitched together, as at 13. strings 14 are secured to the ends of theloop and in practice are threaded through the eyes 8 and extended rearwardly and attached to the handle members. In order to hold the loop against buckling transversely longitudinally extending inserts 15 are sewed between the' tapes 12 at diametrically opposite points of the loop. These inserts are preferably formedfrom celluloid but any other material possessing the necessary flexibility, may be employed For the purpose of'drawing the loop taut or into grippingfengagement with the infants head, a finger engaging element 16 slidable on the handle member 6 is provided, to which the ends of thetapes or strings 14 are adapt- Tapes' or or the handle memed to be attachedQ The finger engaging ele ment consists of a rectangular body 17 havmg a dovetail groove 18in one face which slidably receives the-handle member 6, the
latter beingshaped cross-sectionally, as at 19, from its outer end to a point intermediate its ends to conform to the dovetail recess. oppositely extending rounded extensionsQO, extending at right angles to the handle member 6, project from the opposite ends of the rectangular body.
In the modification disclosed in Figure 6 the handle members are stamped from relatively light and wide gage metal. Inthis instance a rectangular sleeve 21 provided with a head 22 at one end is received on and attached to the outer end of the handle member 5, and receivesthe outerend of the other handleinemberfi as illustrated. The body 17 of the finger engaging member is slidab'le on the handle member 5 and is formed with oppositely extending lugs 23 at llU threaded through the eye of the handle memer 5 and extended rearwardly along the iiandle member and the loop brought rear- I wardly along the opposite 'tace oi": the handle member and held against movement, as ilus-- trated in Figure 8. 1th the loop thus posiinserted through the eye of the 1ne2'-.ber 6 which is now inserted into operative position and engaged with the spherical element 9. The loop being now disposed between the arms 7 is engaged around the infants head either by means of thehuman hand or a suitable surgical instrument. The strings or tapes are then wrapped about the finger engaging member to secure the loop against displacement. With the knob or spherical element placed against the palm of the operato'rs hand and the loop tensioned, by exerting manual strain upon the finger engaging element, the device is drawn outwardly.
lVhat is claimed is 1. In an obstetrical instrument, a pair of separable handle members arranged in opposed relation and having oppositely curved arms at one end, a flexible loop adjustable between the arms and slidably connected therewith, and means associated with the handle members for maintaining tension on the loop.
2. In an obstetrical device, a pair or" detachablyconnected handle members arranged in parallel relation and having their forward ends offset, a flexible human head embracing loop between the offset ends and slidably connected therewith, and afinger engaging element slidable on one of the handle members with which the loop is adapted to be connected whereby the latter may be maintained under tension upon movement of the finger engaging element in an outward'direction.
3. In an obstetrical device, a pair of detachably connected handle members arranged in parallel relation and having their forward ends offset, a flexible human head embracing loop between the offset ends and slidably connected therewith, a finger engaging element slidable on one of the handle members with which the loop is adapted to be connected whereby the latter may be maintained under tension upon movement of the finger engaging lement in an outward direction, and pliable inserts carried by the loop to prevent the latter from buckling transversely. V
4. In an obstetrical device, a pair of paral- In use one of the tapes or strings 1a is 1 tioned the handle member is inserted to op' eratlve position and the other tape or string lel handle members, a loop slidably connected with the adjacent ends of the handle members, tapes carried by the ends of the loop, and a tensioning finger grip associated with the. handle members and engaged by the tapes to maintain the same under tension.
5. In an obstetrical device, a pair of parallel handle members, a loop slidably connected with the adjacent ends of the handle members, tapes carried by the ends of the loop, and a longitudinally shiitable element to which the tapes are anchored and adapted to be shifted in a rearward direction to tension the loop abont the object.
