Description

Lateral perineal incision model

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to perineum side is cut model.

Background

The female perineum refers to the soft tissue between the vaginal orifice and the anus, and consists of the skin and the perineum (i.e., the central tendon of the perineum). The perineum is usually only 2-3 cm long, and can be extended to about 10cm due to the stretching effect during production. The lateral perineotomy is to make an oblique incision at the perineum to prevent the perineum of the puerpera from being torn, protect the pelvic floor muscles and ensure that the fetus can be delivered successfully. Lateral perineotomy is mainly applicable to the following conditions: 1. during delivery, the perineum is tighter, the perineum is longer, the tissue is hard and tough or dysplasia, inflammation, edema or perineum can not be fully expanded when meeting an urgent delivery, and the fetal head is estimated to be cracked to more than II degrees when being delivered; 2. asymmetry of the head-pot due to various reasons (e.g., large, malposition of fetal head); 3. the perineum of the puerpera is cut and sewed, or the scar is large after the repair, which affects the perineum expansion; 4. obstetric forceps for midwifery, fetal head aspirator for midwifery or birth midwifery hip position vaginal delivery; 5. premature delivery, intrauterine growth retardation or intrauterine fetal distress (e.g., abnormal fetal heart, turbid amniotic fluid) requires relief of fetal head pressure and early delivery. The lateral perineal incision is performed 3-5 minutes after local anesthesia, and when the labor pain starts, the middle finger and the forefinger of the left hand stretch into the vagina to prop up the vaginal wall on the left side. The right hand is with perineum incision scissors, the scissors are perpendicular to the skin, and the perineum is cut in the 45-degree direction from the left side of the posterior joint midline of the perineum when the perineum is tight. The direction of 60-70 degrees is adopted when the perineum is highly distended so as to avoid damaging the rectum. The mucous membrane, the muscular layer, the subcutaneous fat and the skin layer are sutured layer by layer after the fetus is delivered. The perineal lateral incision is an operation which needs to be urgently developed when meeting difficult labor and is an operation which is necessary for a gynecologist, no special training model for the perineal lateral incision exists at present, the gynecologist frequently gropes the experience in clinical practice, experience is continuously accumulated in the actual operation process, but the side cutting angle and the length are not ideal due to insufficient experience of a beginner, the anus and the rectum of a patient are possibly damaged by more or too small side cuts, the defecation of the patient after the operation is influenced, the recovery time of the patient after the operation is easily increased by the side cutting length process, and the abundant epistaxis that cuts of perineum blood supply is more, increases beginner's confusion easily, consequently to beginner's design a side cut model be favorable to increasing its operation proficiency, increases clinical experience, provides the side cut success rate and reduces the complication incidence, is favorable to patient's postoperative to recover.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the weak point among the prior art, provide a perineum side-cut model, can simulate the different stages of production process through this model, and then select the operation opportunity to train for perineum side-cut.

In order to solve the technical problem, the utility model adopts the following technical scheme: a lateral perineal incision model comprises a bottom plate, wherein a human body model block is fixed on the upper surface of the bottom plate, the human body model block consists of a simulated abdomen, a simulated thigh and a simulated hip, and the human body model block consists of an outer shell and a sponge;

the artificial vagina and anus integrated device is characterized in that two mounting sockets are formed in the blocking part of the human body model block, an artificial vagina insertion block and an artificial anus insertion block are respectively inserted into the two mounting sockets, the artificial vagina insertion block comprises a rubber shell and a rubber inner layer, the rubber inner layer surrounds to form a vagina cavity, a sponge layer is filled between the rubber shell and the rubber inner layer, red liquid is absorbed by the sponge layer, the rear part of the vagina cavity is connected with a rubber cervical sac, and the rubber cervical sac is positioned in the sponge of the artificial abdomen; the inside of the simulated anus insert block is provided with an anus cavity, the rear side of the anus cavity is connected with a closed sac cavity, and yellow liquid is filled in the sac cavity;

the bottom plate is fixed with a support, the support is located on the rear side of the simulation belly, a screw rod is connected to the support in a threaded mode, the screw rod is arranged in the front-back horizontal direction, a hand wheel is fixed to the rear end of the screw rod, a baby head simulation ball is fixed to the front end of the screw rod, and the baby head simulation ball is located behind the rear end of the rubber cervical capsule.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the novel technique can be through the different stages of simulation production process, and then select the operation opportunity to train for the perineum side is cut, and the incision that comes simulation perineum side through removable emulation vagina module and emulation anus module cuts closes, promotes beginner's perineum side and cuts the proficiency of technique, conveniently deals with clinical proruption situation, promotes patient's cure rate and reduces the incidence of complication.
