US 4,230,116 A · Tubal ligation instrument with anesthesia means

Abstract

The tubal ligation instrument of the present invention includes structure for ligating anatomical tubes within the human or animal body, and structure for anesthetizing the anatomical tubes being ligated. An example of an anatomical tube is a Fallopian tube. The instrument further includes a structure for grasping the anatomical element. The grasping structure extends through a channel in the instrument housing. Usually the grasping structure is a rod having forceps tongs at one end with a flat surface formed on a side portion of the rod. Consequently, the rod does not occupy the entire housing leaving a channel between the rod and the housing. On an outside surface of the instrument housing is an anesthesia receiving means, typically a stopcock. A channel through the stopcock, through which anesthesia may flow, is capable of communicating with the channel between the rod and the housing. The application of anesthesia to an anatomical element is accomplished by introducing the anesthesia through the stopcock and into the unoccupied channel of the housing. Thus, a surgeon directing the end of the instrument to an anatomical element can apply an anesthetic agent to the anatomical element intraabdominally, by the method of the present invention.

In a tubal ligation instrument of the type having a housing, an elastic ring support means carried by said housing, an elastic ring displacement means, a means for causing a relative movement of said support means to said displacement means for displacing an elastic ring off of said support means in a manner to perform a tubal ligation, the improvement which comprises:

(a) an anatomical element grasping means slidable in said support means, with a channel between said grasping means and said support means;
(b) a means for receiving an anesthetic agent on said housing, said receiving means having a channel therethrough, said grasping means adapted so that said channel between said grasping means and said support means communicates with the channel of said receiving means so as to introduce an anesthetic agent to a grasped anatomical element;
(c) actuating means for reciprocally sliding said grasping means axially along said support means, said receiving means communicating with said channel between said grasping means and said support means during only a portion of said reciprocal sliding motion.

A tubal ligation instrument for displacing at least one elastic ring onto an anatomical element or elements and for anesthetizing said element or elements comprising:

a housing;
an elastic ring support means having a portion thereof adapted for supporting one or more elastic rings thereon, said support means being slidable in said housing;
an elastic ring displacement means attached to said housing, said support means being slidable in said displacement means, said elastic ring support portion of said support means adapted for extending beyond said displacement means;
a means for causing a relative movement of said support means to said displacement means for displacing one or more elastic rings off of said support means;
an anatomical element grasping assembly slidable in said support means;
a portion of said grasping means not occupying said support means so that a channel is formed between said grasping means and said support means;
a means for receiving an anesthetic agent positioned on a surface of said housing, said anesthetic receiving means having a channel therethrough, said grasping means and said anesthetic receiving means being adapted so that said anesthetic receiving means channel communicates with the channel between said grasping means and said support means, so that an anesthetic agent may be introduced through both of said channels to anesthetize an anatomical element, actuating means for reciprocally sliding said grasping means axially along said support means, said receiving means communicating with said channel between said grasping means and said support means during only a portion of said reciprocal sliding motion.
