Instruments for Repair of a Prolapsed Vagina.
The top three devices are toggle bolts and require a detachable sharp needle for placement at the hair line. Direct placement of horizontal mattress sutures requires the use of stents to prevent the heavy suture material from cutting through. Hog rings can be placed bilaterally at the hair line with the applicator to serve as rings for a shoe lace pattern. Generally, three or four retention sutures or "bars" are placed loosely enough to permit urination. These are all readily removable retention devices for when the cow goes into labor.
