Description

Technical Field

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

[0002] In gynecological laparoscopic surgery, the uterine manipulator is a key auxiliary tool used to manipulate and fix the position of the uterus, thereby providing a clear field of view and reducing the difficulty of surgery. The existing uterine manipulator has the problem of only being able to push forward and having a small swing angle to the left and right, which limits the flexibility and scope of the operation.

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

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