The utility model relates to a novel uterus holder relates to medical equipment technical field for solving the problem that the internal tissue of uterus in prior art is extremely easy to fall into the gap between two adjacent uterus umbrella long bones, this not only can influence the definition of operation visual field, still can cause certain interference to the precision of operation operation, including: uterus holder body, uterus umbrella subassembly and storage spare, the storage spare installs on the uterus holder body, the uterus umbrella subassembly includes the hollow umbrella stem, umbrella face and multiple umbrella bones, one end of umbrella stem removes setting in the storage spare, the storage spare is used for accomodating the uterus umbrella subassembly, the other end of each umbrella bone rotates and installs in the umbrella stem, the umbrella face covers on the umbrella bone, each umbrella bone with the umbrella stem all is provided with umbrella bone angle adjusting spare, the rotation included angle between umbrella bone and the umbrella stem is arranged 0~90 DEG.

This utility model discloses a disposable uterine manipulator, including a manipulator body, a manipulator rod, a guide rod inserted inside the manipulator rod, and an expansion airbag (annular airbag) surrounding the manipulator rod. A fixing airbag for uterine manipulation is connected to the guide rod. The fixing airbag includes multiple directional expansion airbags arranged circumferentially around the guide rod. A limiting strip is provided on the inner wall of the directional expansion airbag along the length of the guide rod, and a limiting portion is provided on the limiting strip. The expansion airbag and the fixing airbag are respectively connected to an air pump via gas pipelines. By inflating the expansion airbag, it can adapt to vaginas of different sizes and shapes, and also perfectly and evenly act on the entire fornix, providing a favorable environment for subsequent uterine manipulation. Simultaneously, inflating the fixing airbag fills the entire uterine cavity, effectively meeting the needs of uterine manipulation. Furthermore, the expansion airbag and the fixing airbag can be used as disposable consumables, effectively reducing the risk of cross-infection from surgical instruments.

This utility model discloses a uterine lifter for gynecological surgery, comprising an adjusting rod, a uterine support component, a uterine lift assembly, and an adjusting part. The uterine support component is disposed on the outer wall of the adjusting rod, the uterine lift assembly is disposed at the end of the adjusting rod near the uterine support component, and the adjusting part is disposed at the end of the adjusting rod away from the uterine lift assembly. This utility model utilizes the adjusting part and the uterine lift assembly located on one side of the adjusting rod. When the operator adjusts the uterine lift position by pressing the adjusting handle, a sliding bolt on one side of the adjusting handle slides on the inner wall of the adjusting scale. The operator can observe the height of the uterine lift by the adjusting rod based on the angle drawn by the sliding bolt along the arc of the adjusting scale. When the uterine lift position is suitable for surgery, the operator can fix one side of the sliding bolt using a fixing nut. When the fixing nut is connected to the sliding bolt, it clamps the adjusting scale, thereby fixing the position of the adjusting handle and simultaneously fixing the uterine lift position.

A system includes a control console, a laparoscopic instrument, and a uterine manipulator. The laparoscopic instrument includes a first proximity sensor element. The uterine manipulator includes a base and a shaft extending distally from the base. The shaft includes a distal end dimensioned to be inserted into the uterus of a patient and a second proximity sensor element located at the distal end. The proximity sensor elements are configured to cooperatively generate a distance signal indicating a distance between the proximity sensor elements. The control console is configured to receive the distance signal from either the first proximity sensor element or the second proximity sensor element and calculate a corresponding distance between the proximity sensor elements. The control console is configured to compare the corresponding distance with a threshold distance and generate an alert signal when the corresponding distance is smaller than the threshold distance.
