[0002] In gynecological surgeries in the lower abdomen and other areas, a laparotomy pelvic hook is often used. It is also called a pelvic hook, an abdominal pelvic hook, or a laparotomy hook. Its function is to pull the intestines and other organs in the opened abdominal wall, so that the tissue is pulled apart to reveal the surgical area for easy exploration and operation.

[0003] The laparotomy pelvic hook in the prior art mainly includes a hook portion bent at the front and a connecting rod connected to the rear end of the hook portion, which can be connected to the abdominal wall retractor through the connecting rod. The hook portion is mainly used to hook and pull the intestines and other tissues in the abdominal wall. For example, the Chinese authorized patent with application number 202120308757.2, entitled An abdominal wall retractor for ovarian laparotomy, wherein the component "retractor 3" is the laparotomy pelvic hook.

[0004] Due to the different abdominal fatness and body shapes of patients, in order to meet the needs of different patients, the existing laparotomy pelvic hooks are equipped with a variety of sizes and specifications, and 2 to 3 types are commonly used. The need to select the appropriate size during surgery will result in more instruments being arranged next to the operating table, taking up space, and it is also cumbersome to compare the appropriate size. And due to the large individual differences, even if there are multiple sizes, it is still easy to have inappropriate sizes. If a larger pelvic hook is used, it cannot be properly placed in the abdominal cavity, and it is easy to cause certain damage to the patient's abdominal wall; when a smaller size is used, the flat intestines are easy to slip out from the empty areas on both sides of the hook, resulting in the hooks on both sides not being able to pull in place, affecting the operation.
