Description

Abdominal surgery simulation training device

The present invention relates to a simulation training device for laparotomy, in particular to a training device for laparoscopic surgery through a natural orifice.

Hernia surgery is a very common operation in surgery. The traditional hernia surgery is sutured with the tension of its own tissue (Tissue-to-tissue repair). However, it is often accompanied by a large wound after the operation. Pain, slow recovery, and high recurrence rate lead to prolonged postoperative recovery time, and large wounds also increase the chance of postoperative infection, resulting in obvious scars and affecting the appearance of patients.

Instead, tension-free mesh repair is performed with artificial omentum. This operation uses an artificial mesh larger than the hernia gap to repair and strengthen the damaged abdominal wall gap. The postoperative wound is relatively painless. The recovery time is relatively short, and the recurrence rate is relatively low, which has become the mainstream of hernia repair.

In recent years, with the improvement of laparoscopic instruments and the accumulation of surgical experience, laparoscopic technology has also been successfully used in hernia surgery. It is a type of minimally invasive surgery. Compared with traditional hernia surgery, the wound caused by this surgical method is smaller. It speeds up the recovery time after surgery and also achieves the expectation of no scars on the body surface.

With the popularity of endoscopic and laparoscopic surgery, the training mode of surgeons in laparoscopic surgery has also shifted from traditional abdominal surgery to laparoscopic surgery of the navel.

Hernia (Hernia), commonly known as a hernia, medical hernia refers to an organ, such as the intestine, leaving its original position through the hole in the cavity. There are many different types of hernias, and they tend to occur in the abdomen and groin. Inguinal hernias are more often in the form of inguinal hernias, but they can also be femoral hernias. Basically, groin hernia is a general term for a hernia that occurs in the area. Others include hiatal hernia, incisional hernia, and umbilical hernia. Hernias and more types of hernias.

Both abdominal and groin hernias present with varying degrees of symptom distress, which can include pain, or discomfort when coughing, exercising, or even going to the toilet. And these symptoms may be alleviated at the end of the day or even lying down. When pressed, the protruding part may become enlarged. Groin hernias are more likely to occur on the right side of the body than the left. The biggest concern for healthcare providers with this condition is volvulus, which occurs when the blood supply to the bowel becomes blocked, often resulting in severe pain or tenderness in the area.

The above are "external hernias" that can be seen on the outside of the body. In addition, there are also "internal hernias" that occur inside the body. Yes, but diaphragmatic hiatal hernia or esophageal hiatal hernia often cause gastroesophageal reflux when eating but may also cause chest pain commonly known as "burning heart" when eating; in addition, hernias caused by trauma are called traumatic hernias.

Because laparoscopic surgery is a very common operation in surgery, and laparoscopic surgery is an operation that requires precise operations. There are many important organs in the abdominal cavity. For surgeons, laparoscopic surgery is likely to injure the nerves and blood vessels of these organs during the operation, so a lot of practice is needed to reduce this situation; Due to Taiwan's laws and regulations, this type of surgery usually needs to go abroad to participate in general training camps, which takes more time and money, and it is impossible to practice repeatedly.

With the gradual increase in the difficulty of laparoscopic surgery, senior doctors may not be willing to give a lot of new opportunities to novice doctors, so the way of simulation training is the best way. At present, with the development of virtual reality and augmented reality There are many related surgical trainings that have begun to use virtual reality to practice for novice doctors, such as laparoscopic appendectomy and laparoscopic cholecystectomy. However, although virtual reality allows students to understand all the steps of surgery, it does not have the touch of real surgery.
