Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an enterostomy positioning device. Background Art

[0002] Enterostomy is one of the widely used surgical methods in the field of surgery and is of great significance for the treatment of various intestinal diseases. However, this operation is not without risks. According to statistics, about 80% of patients with stomas will experience complications of the stoma and the skin around the stoma. The occurrence of these complications is closely related to the choice of stoma location. Proper stoma positioning can not only significantly reduce the incidence of complications, but also help patients adapt to stoma life more quickly, thereby improving their quality of life. At present, the commonly used stoma positioning method is the triangulation positioning method, such as selecting the navel, the anterior superior iliac spine and the pubic symphysis as reference points, connecting the three reference points to form a triangle, and connecting the three reference points to the midpoint of the contralateral line to find the center of gravity of the triangle as the predetermined position of the stoma. Using this position, the stoma is accurately positioned and is widely used in clinical practice.

[0003] However, currently in clinical practice, triangulation positioning is usually achieved by manual drawing using a ruler and a pen. The operation process is complicated and time-consuming, especially in emergency situations. This method is particularly inappropriate. In addition, the manually drawn lines leave many marks on the patient's abdomen, which not only affects the appearance, but may also interfere with the surgical field of view, causing unnecessary trouble to the doctor.

[0004] In addition, according to the type of surgery and patient needs, intestinal stomas can be divided into various types such as permanent colostomy, ileostomy, transverse colon double-lumen stoma, etc. Different types of stomas have different requirements for location. However, existing stoma positioning devices lack sufficient flexibility and personalization, and cannot be flexibly adjusted according to the patient's body shape and surgical needs, resulting in inaccurate positioning and increasing the risk of complications.
