Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a uterine lifting device for gynecological laparoscopic surgery. Background Art

[0002] During laparoscopic gynecological surgery, a uterine manipulator is a key auxiliary tool used to manipulate and stabilize the uterus, providing a clear field of view and reducing surgical difficulty. Existing uterine manipulators are limited to forward movement and have limited left and right swing angles, limiting surgical flexibility and operating range.

[0003] Most of the uterine manipulation devices currently on the market achieve forward and backward movement through harness traction, but when left-right swinging is required, existing equipment often cannot meet the requirements. This limitation makes it difficult for doctors to perform multi-angle operations on the uterus during some complex gynecological laparoscopic surgeries. In addition, the diameter of the uterine manipulation cup cannot be adjusted, and different models of uterine manipulation cups need to be replaced to suit people with different uterine sizes. In addition, the head shape of the uterine manipulation rod is single and cannot effectively fix the uterus, affecting the effectiveness and safety of the operation.

[0004] Therefore, it is necessary to propose a uterine lifting device for gynecological laparoscopic surgery to solve the above problems. Summary of the Invention
