Description

Perineum lateral incision stitching teaching aid

Technical Field

The utility model relates to a medical treatment auxiliary articles for use field specifically is a teaching aid is sewed up to perineum side is cut.

Background

The lateral perineal resection is used for avoiding serious perineal laceration and reducing perineal resistance during vaginal delivery, so that the delivery of a fetus is facilitated, the second labor stage is shortened, the pelvic floor function is protected, and mother-infant complications are reduced. The lateral perineotomy is characterized in that an oblique incision is made after the perineum is combined with the median line which is about 0.5 cm, the oblique incision is 45 degrees with the median line, the incision size is selected according to the conditions of a parturient and a fetus, the incision size is generally 4-5 cm, and the perineum incision stitching can be performed after the fetus and a placenta are delivered. When an incision is sutured, an operator exposes the incision top end of the vaginal mucosa with the index finger and the middle finger of the left hand, the vaginal mucosa and submucosal tissues are sutured discontinuously or continuously from the position which is more than 0.5 cm above the incision top end by using 2-0 absorbable suture until the position of an inner ring of a virgin's eye is knotted, then the muscular layer is sutured discontinuously by using 2-0 absorbable suture, and finally the skin is sutured discontinuously by using the silk thread or the skin is sutured continuously by using 3-0 absorbable suture. The suture is required to be aligned layer by layer according to anatomical levels, the suture needle is not too tight and too dense, and no dead space is left. The times of needle entering and exiting and suture knots are reduced as much as possible, and attention is paid to the fact that the needle and the thread do not penetrate through the rectal mucosa. Intensive suture skill training is required for obstetricians and midwives with poor operating opportunities and inexperience. At present, the pig tongue and the cow tongue are used for simulation suture training in the training of clinical obstetricians and midwife, the smell of the pig tongue and the cow tongue is bad, a large amount of time is spent for cleaning, the pig tongue and the cow tongue are not easy to store, and the pig tongue and the cow tongue can be used only once; there is also cloth-model simulation suture training, but the structure is relatively simple, and the actual perineal incision dissection level and tissue structure cannot be well simulated, so that the training effect is difficult to achieve.

Therefore, designing a lateral perineal incision stitching teaching aid which can be closer to the real shape and environment of the perineal incision becomes a problem to be solved urgently in the field of medical auxiliary products.
