SIJRGICAL INJECTOR Filed Dec. 5, 1921 Patented May 19, 1925 UNITED STATES PATENT OFFICE.
HANS FISCHER, 0F LUCERNE, SWITZERLAND.
SURGICAL INJECTOR.
Application filed December 3, 1921. Serial No. 519,576.
useful Improvements in Surgical Injectors,-
of which the following is a specification.
The object of this invention is to provide a surgical injector whereby a medicinal substance, or a disinfectant, can be injected in such a manner that it issues uniformly, or nearly so, along the passage into which the instrument is inserted.
An embodiment of the invention is shown in the accompanying drawing, in which,
Fig. 1 is a longitudinal section of theinstrument with the parts in position prior to use, and 4 Fig. 2 is a plan View thereof.
F gs. 3 and l are respectively a longitudinal section and a cross section on the line A-B showing the position of the parts after use.
The instrument shown comprises a rod a of elliptical cross section, having throughout its length a channel I). l/Vithin this channel lies a rod 0, fitting against its sides and connected to the rod (6 by two links cl, each link having its ends pivoted in recesses d in the rods a and 0 respectively. The rod 0 has a handle By pushing and pulling this the rod 0 can be caused to rise and fall in the channel 7), remaining always parallel with the floor thereof.
lVhen the rod 0 is lying on the floor of the channel Z), as shown in Fig. 1, the upper part of the latter is free, and forms a groove into which the medicinal or disinfecting substance to be administered is placed. The instrument is then inserted into the passage, and the handle is pushed, causing the rod 0 to rise and push out the said substance, distributing it uniformly along the length of the passage.
I do not limit myself to the use of a rod of elliptical cross section, and may make the rod (t of whatever cross section is best adapted for the passage to be treated.
l/Vhat I claim as my invention and desue to secure by Letters Patent of the United States is 1. A surgical appliance for the purpose set forth comprising a rod having a longitudinal channel therein, a second rod in said channel, of a crosssection filling the width but not the depth of said channel, a handle fixed to said second rod and links connecting said second rod to said first rod, allowing said second'rod. to be raised and lowered in said channel, substantially parallel with the floor thereof, by pushing and pulling said handle.
2. A surgical appliance for the purpose set forth; comprising a rod having a longitudinal channel therein, and having recesses in the floor of said channel, a second rod in said channel, having recesses facing the floor of said channel and having a cross section fillingthe width but not the depth of said channel, a handle fixed to said second rod and links having their ends pivoted to said first rod and said second rod respectively, within the recesses in said rods, allowing said second rod to be raised and lowered in said channel substantially parallel with the floor thereof, by pushing and pulling said handle.
In witness whereof I have signed this specification in the presence of two witnesses.
