OBSTETRICAL INSTRUMENT.

Specification of Letters Patent.

Patented April 24, 1906.

A li tion fil d December 4,1905. Serial No. 290,249.

To aZZ whom it may concern:

Be it known that I, J GEN G. GOTTLIEB, a citizen of the United States, residing at Fessenden, in the county of I/Vells and State of North Dakota, have invented certain new and useful Improvements in Obstetrical Instruments, of which the following is a specifi cation.

My invention relates to improvements in obstetrical instruments or forceps for veterinary purposes or for use in emergency in childbirth.

It has for its object, among other things, to provide for the removal of the fetus or young in normal condition or alive, or by piecemeal when necessary, with perfect immunity from injury to the patient or risk to life, and to do this with facility and effectiveness.

To these ends said invention consists of certain structural features substantially as hereinafter fully disclosed, and particularly pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure l is perspective view thereof in open position. Fig. 2 is a broken vertical longitudinal section showing more fully the removable teeth, cutters, or fangs for use in connection with the jaws of the instrument or forceps. Fig. 3 is a broken side or edge view of the jaws, having fitted thereon rubber or leather caps for using the instrument for the removal of the fetus or young in normal condition or alive. Fig. 4 shows disassembled views of the teeth, cutters, or fangs carried by the aws of the instrument or forceps. Fig. 5 is a cross-section taken through said jaws.

In carrying out my invention I employ two jaw members 1 1, having integral handles 2 2, suitably passed one through the other and pivoted together, as well understood, and adapted at their free ends, preferably as shown at 2 2, for convenience in obtaining the requisite purchase thereon in manipulating the instrument or forceps. These jaws are preferably of what may be termed goosebill" shape for presenting a broad surface to the parts to be operated upon or grasped and are of unequal length, one being much shorter than the other, as disclosed, and are adapted to be equipped with teeth, cutters, or fangs 3 3. Said jaws are more or less depressed or dished to render them more effective than would otherwise be the case in securing a gripping action therebetween and the object engaged. The cutters, teeth, or fangs 3 3, having screwthreaded extensions or shanks removably applied in any number, singly, two, or three, for an operation to the aws, as aforesaid, are bevel-edged and produced in various forms and sizes to render them effective for readily mutilating, crushing, cutting, or gripping the bones, the flesh, or the tissue, as may be required in event it should be necessary to remove the fetus or young by piecemeal. For facilitating this purpose these cutters or teeth are adapted, by suitably turning them, to be changed as to their relative angle of presentation according to the requirements of the work to be performed. It will be appreciated that said cutters or teeth are brought into use only in cases of emergency, as well understood, in order to save life at the expense of the destruction of the fetus or young.

In the ordinary use of the instrument or forceps, as in effecting the removal of the fetus or young normally, rubber or leather caps or covers 4 are slipped upon the jaws thereof, as shown, the purpose of which is obvious.

The instrument is highly effective in action, and by means thereof the required obstetrical operation may be performed with facility and entire immunity from injury to the patient or risk to life, as aforesaid.

It is obvious that my forceps or instrument is effective equally for use upon animals, as well as upon persons, as above intimated, and for normally disposing the fetus or young in event the position of the latter may become distorted or out of the natural.

1. An obstetrical instrument, comprising handle-equipped pivoted-together jaw members, oblong in the direction of their lengths and dished or depressed in their opposed effective surfaces.

2. An obstetrical instrument, comprising handle-equipped pivoted-together jaw members, oblong in the direction of their lengths and dished or depressed in their opposed effective surfaces, and having the latter provided with cutter or fang receiving openings.

3. An obstetrical instrument, comprising handle-equipped pivoted-together jaw members, oblong in the direction of their lengths and dished or depressed in their opposed effective. surfaces and having the latter equipped with cutters or fangs, a number being arranged upon each jaw member and. those upon one jaw member alternating the cutters upon the other jaw member.

42; A11 obstetrical instrument, comprising handle-equipped pivoted-together jaw members, oblong in the direction of their lengths and dished or depressed in their opposed effective surfaces and having the latter equipped with cutters or fangs removably 111- I0 serted therein, those of one jaw member a1- ternating the cutters of the other jaw 'me'nv ber, said cutters or fangs having laterally-extended cutting edges.

In testimony whereof I affix; my signature in presence of two witnesses.
