Description
Oct. 26, 1937. A. M. PETERSON TROCAR Filed Sept. 21, 1935 M m m vvvw M v FW h M/WM Invenlor 49965 Peienson lg i 5 55115 3}-1 15i A ltomcy Patented Oct. 26, 1937 UNITED STATES PATENT OFFICE 1 Claim.
My invention relates generally to instruments for aspirating cavities of the human body and particularly to a trocar for aspirating cavities in dead human bodies, wherein means is provided for preventing and eliminating clogging of the trocar which occurs in ordinary instruments of this character, and an important object of the invention is to provide an efiicient and simple arrangement of this character.
Another important object of my invention is to provide a trocar which may be cleaned of clogging matter while the same is in use and Without removing the same from the cavity, so that the trocar may be kept clean at all times without interruption to the work.
Another important object of the invention is to provide a more efiicient trocar which enables the operations of aspirating cavities to be performed with much greater facility, and with greater efliciency and speed.
Other important objects of my invention will be had from a reading of the following description in connection with the drawing, wherein for purposes of illustration I have shown a preferred embodiment of my invention.
In the drawing:
Figure 1 is a longitudinal sectional view taken through the embodiment.
Figure 2 is a transverse vertical sectional View taken through Figure 1 approximately on the line 2-2. 1
Figure 3 is an elevational view of the handle portion of the embodiment showing the manual valve thereon.
Referring in detail to the drawing, the numeral 5 generally designates the tubular conduit portion of the trocar which terminates at one end in a piercing point 6 adjacent which are located several holes 1 through which the body fluid is drawn from the body cavity into the bore of the tube 5 and withdrawn at the open opposite end 8 thereof by the suction hose 9 which is attached thereto.
Intermediate the ends of the tube 5 is a flange 10 which abuts one end of the handle I l which is circumposed on the tube 5 and terminates at the' open end of the tube approximately flush therewith as generally indicated by the numeral l2. The handle ll comprises the rounded relatively large diameter portion l3 and the tapering reduced rounded portion I4 which terminates in the flange l5 which provides a shoulder It to be engaged by the adapter H on the suction hose 9, whereby the adapter of the suction hose is firmly connected onto the handle and in communication with the tube 5.
Intermediate the ends of the enlarged portion I3 of the handle is a radial passage l8 which is registered with an opening IS in the side of the tube, and at one side of the opening I8 is a pivot bracket which includes an upwardly or radially outwardly urging leaf spring 2 I. On the bracket 20 is pivoted as indicated by the numeral 22 an operating handle 23 which includes the expanded portion 24 to the underside of which is attached the frustro-oonical compressible material valve 25, the member 23 having on the opposite side of the pivot 22 the portion 26 to be engaged by the fingers to swing the member 23 on its pivot against the opposition of the spring 2|.
As is obvious the spring 2| operates the member 23 into such a position that the compressible valve 25 forcibly engages the side of the handle around the outer end of the opening I 8 and thereby closes the opening i 8, and that pushing the portion 26 of the member 23 toward the handle will open the passage l8 to the exterior atmosphere.
Ordinarily it is necessary to clean a trocar which has become clogged by inserting and operating a cleaning rod therein after having withdrawn the trocar from the cavity and thus interrupt the work. But a trocar constructed in accordance with the principles of the present invention can be cleaned and kept cleaned simply by pressing upon the thumb lever 23 so as to open the Valve 25 and let outside air be drawn into the interior of the tube 5 by the vacuum operating through the hose 9, and without withdrawing the trocar from its operative position in the cavity; since the action of the air coming through the opening l8 and passing through the tube 5 is to push and withdraw the clogging matter from the tube 5 and into the hose 9. For convenience the hose 9 will be connected to a bottle or container having a source of vacuum or suction attached thereto to receive the clogging matter.
Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials, and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjo-ined claim.
What is claimed is:-
A trocar comprising anaspirating tube having a pointed apertured end for insertion; a lateral flange on said tube intermediate its ends, a tubular handle fitted on the aspirating tube opposite said pointed end, said handle having its axially inward end engaged with said flange, an axially inward portion of said handle being provided with a radial opening registering with an opening formed in the side of said aspirating tube, and a manually operated spring-pressed valve on said handle and normally closing said radial opening.
