Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable three-dimensional suspension device for uterine surgery, and more particularly to a suspension device that achieves dynamic adjustment of the length and tension of the suspension rope through a movable card structure, suitable for multi-angle precise adjustment of the uterine position during laparoscopic surgery. Background Technology

[0002] In uterine surgery, surgeons often need to adjust the position of the uterus using a suspension device to expose the surgical field. This requires instruments to adjust the position of the uterus. The traditional method is to use a uterine lifter to lift the uterus. However, due to the complexity of uterine cases, the lifting angle and range of such instruments are limited in actual clinical practice, and they are increasingly unable to meet surgical needs. The adjustable three-dimensional uterine suspension device provided in this application has a large range of adjustment for the position and angle of the uterus. Specifically, the puncture needle is inserted into the abdomen through the laparoscopic port. The puncture needle is manipulated by surgical forceps to sequentially puncture the ligaments on both sides of the uterus. The two ends of the suspension rope are tied to bind the uterus. The puncture needle finds a suitable position and exits from the abdomen, and is secured to segment a by the movable end. The end of the suspension rope is led out through the laparoscopic port and is movable at the end. The device secures segment b, with the first movable clip stopping segment a against the patient's skin surface, and the second movable clip stopping segment b against the patient's skin surface, maintaining the uterus in a position and angle conducive to surgery. When adjusting the high position of the uterine suspension, hold the end of the suspension rope with one hand and press the end clip with the other, causing the end clip to release its restraining effect on segment b. Manually controlling the force of the suspension rope results in segment b being inserted or pulled out slightly, adjusting the uterus's position accordingly. Once the position is adjusted, the end clip is repositioned into segment b, and the pressure on the end clip is released. Under the spring force, the end clip is biased towards the insertion opening b, and segment b is clamped again by the end clip. Traditional uterine manipulators have the following problems:

[0003] 1. Limited adjustment range: It only supports adjustment in a single direction or plane, which cannot meet the needs of complex surgeries;

[0004] 2. Cumbersome operation: During the operation, it is necessary to maintain the original position of the uterus for a short period of time. This requires fixing the uterine manipulator instead of just relying on hand. Hand is not stable, and relying on additional instruments for fixation requires repeated disassembly or re-fixation of the instruments, which prolongs the operation time.

[0005] 3. Insufficient precision: Lack of intuitive length markings makes it difficult to quantify the adjustment range;

[0006] 4. Poor stability: The fixation device is prone to loosening, and the uterus may shift due to changes in traction force during the operation. Summary of the Invention
