  • Truluck Attorney-Salter 8L Michaelson 1 5 7 ABSTRACT A vasectomy procedure and instrument for use therewith that provides for elevating the vas deferens from' the scrotal sac of the patient for severing of the vas while it is in the elevated position, the instrument having an arcuate shaped head provided with a central longitudinally extending groove that acts as a base for the severing tool during the severing operation of the vas.
  • the present invention relates to a vasectomy procedure and instrument for use therewith and has application as a birth control procedure and device since the vas deferens carrying the male sperm is severed,
  • the surgeon performing the vasectomy was required to retain the vas in an elevated position during the severing thereof by grasping the vas with a clamp or the like that held the vas by downwardly extending clamp arms that oftentimes were awkward to manipulate during the severing operation. Further, separating the vas from connective tissue sometimes proved to be a delicate step in the procedure and the surgeon had to be careful to avoid the severing of tissue that could result in trauma to the patient.
  • the present invention relates to a surgical instrument and vasectomy procedure for use thereof, wherein the instrument comprises a handle and a head mounted on the handle, the head including'a body portion having a generally arcuate configuration defined by an outer convex portion and an inner concave portion.
  • the inner concave portion of the surgical instrument as embodied in the subject invention has a central groove formed therein that extends longitudinally of the body portion. It is preferred that the body portion be formed such that it terminates at its distal end in a point, the pointed distal end providing for easy insertion of the instrument through the scrotal incision during the vasectomy procedure.
  • the lateral edges of the body portion of the instrument head define incisive blade edges that may be used to separate connective tissue from the vas deferens prior to the severing thereof. If required, the head may be removably mounted on the handle of the instrument for disposal and replacement by a similar head.
  • the surgical instrument as embodied herein provides for elevating or lifting of the vas deferens from the underneath side during the vasectomy procedure rather than clamping from above wherein the surgeon is able to conveniently retain the vas in the elevated or lifted position free of obstruction.
  • the vas is severed in a simple cut, using the concave portion of the head as a base or backing and the groove as a means for locating the scalpel during the vas severing operation.
  • Another object of the invention is to teach a method of performing a bilateral vasectomy utilizing a surgical instrument that provides for the lifting of the vas deferens from the underneath side for the severing thereof.
  • Still another object is to provide a surgical instrument for use in a bilateral vasectomy that includes a handle and a head mounted thereon, the head having a generally arcuate configuration that enables the vas to be lifted from the underneath side out of the scrotum of the patient for the severing of the vas.
  • Still another object is to provide a surgical instrument having a handle on which a head is mounted, the head being arcuate in configuration, and having a concave side in which a central longitudinally extending groove is formed, the lateral sides of the head defining incisive cutting edges.
  • FIG. I is an exploded elevational view of the surgical instrument embodied in the present invention.
  • FIG. 2 is a sectional view taken along line 2-2 in FIG. 1;
  • FIG. 3 is a fragmentary top plan view with parts shown in section showing the surgical instrument of the present invention in the use thereof during a vasectomy procedure; and I -FIG. 4 is a sectional view taken along line 4-4 in FIG. 3.
  • the surgical instrument embodied in the present invention is illustrated and is generally indicated at I0. It is contemplated that the surgical instrument 10 will be employed in a bilateral vasectomy procedure, although it is understood that the instrument can be utilized for other surgical procedures as required.
  • the instrument 10 includes a handle generally in-- dicated at 12 on which a head portion generally indicated'at 14 is removably mounted.
  • the handle 12 is formed with an elongated body portion 16 to which a fitting 18 is fixed at a tapered end thereof.
  • a reduced outer shank 20 is joined to the fitting 18 and extends outwardly therefrom.
  • the shank is normally circular in crosssectional configuration, although this configuration may vary as required in the interfitting of the handle 12 to the head portion 14.
  • the head 14 is defined by a fitting 22 having a bore formed therein that accommodates the shank 20 in frictional relation and provides for fixedly mounting of the head 14 on the handle 12.
  • the fitting 22 includes a reduced section 24, to which a conical portion 26 is joined, the reduced section 24 and conical portion 26 having a bore of reduced diameter formed therein for receiving a shank 28 of a body portion 30 of the head 14.
  • the shank 28 of the body portion 30 as fixed in the fitting 22 forms an integral part therewith, and as will be described, the head 14 is formed as a separate unit and may be removably attached to the handle 12 for disposal after use in a vasectomy procedure.
  • FIGS. 3 and 4 a portion of the scrotal sac of a patient is indicated at 50 and prior to the procedure, the upper portion of the sac S0 is prepped and cleansed with an antiseptic solution.
  • the surgeon identifies the vas deferens within the scrotal sac 50 as a fibrous cord by palpation of the scrotal contents between his thumb and index finger.
  • the vas deferens is moved as close as possible to the lateral surface of the scrotal sac 50 and is maintained in this position by traction between the thumb and index finger.
  • the selected area for incision is infiltrated with an anesthetic solution and a small transverse incision indicated at 52 is thereafter made by the surgeon with a scalpel, the length of the incision 52 being preferably about one-half inch.
  • the vas is worked into communication with the incision until it is located near the lateral surface of the scrotal sac 50.
  • the distal end 32 of the head 14 of the instrument 10 is then inserted into the incision 52 medial to the vas 54 such that it projects underneath the vas.
  • the distal end 32 is thereafter moved upwardly and then outwardly through the opstrip the connective tissue sheath from the vas deferens.
  • the small incision below the vas 54 in the connective tissue sheath made by the blade edges may be expanded by blunt dissection using a small straight hemostat.
  • the segment of the vas deferens to be severed is then located between two straight hemostats which are placed through the expanded incision in the connective tissue sheath. Thereafter the head 14 of the instrument 10 may then be employed as a base for facilitating the cutting or severing of the vas 54.
  • the blade of a scalpel 56 is directed by the surgeon against the vas deferens and into the groove 38 as illustrated in FIG. 4, the blade of the scalpel 56 following the course of the groove 38 which defines a guide for the scalpel during the severing operation.
  • the ligated ends are returned to the scrotal sac 50, the surgeon having taken precautions to insure that bleeding points have been coagulated.
  • the skin edges of the opening 52 in the sac 50 are closed by suturing and normally only a single suture is required.
  • An antiseptic spray and then a spray film dressing is applied, the surgeon further being careful to insure that lateral traction of the vas is maintained and that errors in location and immobilization of the vas are avoided.
  • the entire procedure as described may take anywhere from 5 to 30 minutes and can be performed in the surgeons office using the instruments as indicated. After surgery and a short recuperative period at home, the patient may resume his normal activities.
  • the surgical instrument 10 as described hereinabove enables the vas 54 to be elevated from the underside thereof to a point exteriorly of the scrotal sac 50, thereby enabling the vas to be conveniently severed by the surgeon.
  • the sharp distal end 32 of the head portion 14 provides for convenient insertion of the head 14 of the instrument 10 into the incision 52 and through the connective tissue beneath the vas 54 so that the vas can be elevated to appropriately locate it for the severing operation.
  • the incisive edges 46 and 48 also enable the connective tissue sheath the be separated from the vas without traumatic effects and with the vas 54 located in the position as illustrated in FIG. 3, the surgeon is able to quickly and conveniently perform the severing operation with little difficulty.
  • the surgeon employs the groove as a guide for directing the scalpel 56 through the vas in the severing operation. lt'is seen that the instrument 10 provides a convenient and useful tool for the surgeon in performing the bilateral vasectomy with a minimum of time and effort.
  • a surgical instrument for use in a vasectomy procedure comprising a handle and a head mounted on said handle, said head including a body portion having a generally arcuate configuration defined by an outer convex portion and inner concave portion, the inner concave portion having a central groove formed therein that extends longitudinally of said body portion, the body portion terminating in a pointed distal end, and the lateral edges of said body portion forming incisive blade edges.
