Description

Technical Field

[0001] The present invention 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 can dynamically adjust the length and tension of a suspension rope through an active card structure, and is suitable for multi-angle precise adjustment of the uterine position during laparoscopic surgery. Background Art

[0002] During uterine surgery, doctors often need to adjust the position of the uterus through a suspension device to expose the surgical field of view, which requires the use of instruments to adjust the position of the uterus. The traditional way is to lift it with a uterine manipulator. Due to the complexity of the characteristics of uterine cases, the lifting angle and range of such instruments are limited in actual clinical practice, and are increasingly unable to meet surgical needs. The adjustable three-dimensional uterine suspension provided in the present application has a large adjustment range for the position angle of the uterus. Specifically, the puncture needle is inserted into the abdomen through the laparoscope port, and the puncture needle is operated by surgical forceps to sequentially pierce the ligaments on both sides of the uterus, and the two ends of the suspension rope are knotted to bind the uterus. The puncture needle finds a suitable position to pass through the abdomen and clamps section a through the first end movable clamp, and the end of the suspension rope is led out through the laparoscope port and clamped through the end movable clamp. The segment b is stuck, and the movable clamp at the front end stops segment a on the surface of the patient's skin, and the movable clamp at the end stops segment b on the surface of the patient's skin, so that the uterus is kept in a position and angle that is convenient for surgery. When the high-end position of the uterine suspension needs to be adjusted, the end of the suspension rope is pulled with one hand, and the end clamping tongue is pressed with the other hand, so that the end movable clamp releases the stopping effect on segment b, and the force of the suspension rope is manually controlled, which results in segment b being inserted or pulled out again, and the uterus will adjust its position accordingly. After the position is adjusted in place, the end movable clamp is again inserted into segment b, and the pressing force on the end clamping tongue is released. Under the action of the spring, the end clamping tongue is biased toward the embedding port b, and segment b is clamped to the end movable clamp again; the traditional uterine manipulator has the following problems:

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

[0004] 2. Complicated operation: During the operation, the original position of the uterus needs to be maintained for a short time, which requires the uterine manipulator to be fixed instead of just holding it by hand. The hand-held stability is poor, and the fixation with additional instruments requires repeated disassembly or re-fixation of the instruments, which prolongs the operation time.

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

[0006] 4. Poor stability: The fixation device is easy to loosen, and changes in pulling force may cause the uterus to shift during surgery. Summary of the invention
