Description

Teaching device for laparoscopic extraperitoneal radical prostatectomy

Technical Field

The utility model relates to the technical field of medical models, in particular to a teaching device for laparoscopic extraperitoneal radical prostatectomy.

Background technique

The prostate is an accessory gland of the male reproductive system, located between the bladder and the urogenital diaphragm, surrounding the root of the urethra. Its shape and size are similar to a slightly flat chestnut. The prostate is an unpaired solid organ, composed of glandular tissue and muscle tissue. The horizontal diameter of the upper end of the prostate is about 4 cm, the vertical diameter is about 3 cm, and the front-to-back diameter is about 2 cm. The surface is covered with a fascial sheath, called the prostatic capsule. There is a prostatic venous plexus between the capsule and the prostate.

At present, people's understanding of the function of the prostate and the impact of its pathology on other organs is generally obtained through corresponding theoretical knowledge and picture information. These channels cannot intuitively and vividly give the function of the prostate and the impact of its pathological changes on other organs, making it difficult for people to understand the function of the prostate and the reasons why its pathological changes affect other organs.

Furthermore, in medical teaching, teachers and students are often required to perform simulated medical operations. However, some surgical operations, such as puncture and laparoscopy, cannot be performed multiple times on the human body. For medical staff, necessary practice and practical operations are the only way to improve medical technology. Obviously, medical students and medical staff cannot practice operations on patients, so it is very necessary to simulate the operation of laparoscopic extraperitoneal radical prostatectomy as realistically as possible on a human model.
