Problems solved by technology

In the past, the surgical instruments were only used for lifting the uterus or only for the separation of drug administration, which was poor adaptability and inconvenient to use, especially in the past. , while the hard straight pendulum lever does not have a soft ball, it is easy to damage the uterine wall, and it is difficult to swing the uterus
The positions of the cervical pessary and vaginal seal cannot be adjusted, it is difficult to adapt to the anatomical relationship between the reproductive system and the urinary system, and it is difficult to clearly reveal the adhesions of the uterus and pelvis and the parts to be resected and stripped
[0003] The existing uterine lifter has the following defects: the existing uterine lifter requires multiple people to operate synchronously, resulting in complicated surgery and troublesome operation, and the biggest problem is that the use of the uterine lifter is not safe and prone to misoperation

Embodiment 1

[0037] According to an embodiment of the present invention,

[0038] see figure 1, an automatic uterine lifter, including a bed body 1 and a sliding sleeve 2 sliding along the edge of the bed body 1, the two sliding sleeves 2 slide synchronously on both sides of the bed body 1, and the sliding sleeves 2 on both sides are respectively Through the first support column 3 and the second support column 4 for up and down adjustment, the first support column 3 and the second support column 4 drive the support curved beam 5 and the lifting mechanism 6 to move up or down as a whole when the sliding sleeve 2 moves up and down. Move downwards to be flush with the roughly horizontal plane of the cervix. The upper ends of the first support column 3 and the second support column 4 are fixed to support the curved beam 5. The support curved beam 5 is a stainless steel structure with symmetrical bending at both ends. The support curved beam 5 There is a sliding palace-lifting mechanism 6 on t...

Embodiment 2

[0041] see figure 1 The first ram 11 and the second ram 12 are respectively erected on the two sides of the bed body 1, and the bottom of the sliding sleeve 2 is processed with a concave chute 21, and the sliding sleeve 2 passes through the first ram 11 and the second ram 12. The ram 12 is inserted into the chute 21 to reciprocate and slide, and the first ram 11 and the second ram 12 are used to guide the sliding of the sliding sleeve 2. The outer wall of the sliding sleeve 2 is connected to the side column 22, and the side column 22 is Process the slots for the first support column 3 and the second support column 4 to pass through, and the side column 22 port is engaged along the axis with a locking button 221 against the outer walls of the first support column 3 and the second support column 4, the locking button 221 After being rotated against the side column 22, the locking button 221 is used to abut against the first support column 3 and the second support column 4 after ...

Embodiment 3

[0043] see Figure 4-5 , the side peripheral surface of the outer ring 84 is processed with an annular groove 841, and a plurality of retaining pieces 8411 are fixed at equal intervals along the radial direction of the outer ring 84 in the annular groove 841, and pressure sensors are arranged on both sides of each retaining plate 8411 (Fig. not shown), the first side ring 81 is penetrated with a button 811 that can extend into the ring groove 841, the button 811 is inserted into the ring groove 841 and contacts with the blocking piece 8411, the pressure generated by the button 811 acts on the pressure On the sensor, the pressure sensor uploads the signal to the PLC controller, the position of the card master outer ring 84, the plug button 811 is not inserted into the ring groove 841, the outer ring 84 rotates around the inner ring 83, the plug button 811 is inserted into the ring groove 841 to complete the locking, and its insertion The signal of whether the button 811 is inse...

Abstract

The invention discloses an automatic uterine manipulator. The automatic uterine manipulator comprises a bed body and sliding sleeves sliding along the edge of the bed body, wherein a first supportingcolumn and a second supporting column which are used for up-down adjustment penetrate through the sliding sleeves on the two sides respectively; a supporting curved beam is fixed to the upper ends ofthe first supporting column and the second supporting column; and a sliding uterine manipulator mechanism sleeves the supporting curved beam and is used for adjusting the position of uterine manipulator. The automatic uterine manipulator has the advantages that the first supporting column and the second supporting column complete overall ascending or descending of the supporting curved beam when two nuts synchronously rotate, a sliding buckle slides on the supporting curved beam to drive the uterine manipulator mechanism to slide overall, a uterine manipulator rod is driven to adjust the up-down position by driving a rotating shaft to rotate, if an insertion button is not inserted into an annular groove, a warning is given out, and after the insertion button is inserted into the annular groove, the warning is eliminated, so that the safety of an operator and a patient can be improved, and misoperation is prevented.

Description

technical field [0001] The invention relates to the medical field, in particular to an automatic uterine lifter. Background technique [0002] At present, there are two types of gynecological laparoscopic surgery: pneumoperitoneum and non-pneumoperitoneum (suspension). Regardless of the method, operations such as swinging the uterus, adjusting the orientation of the uterus, and injecting contrast agents or drugs into the fallopian tubes are often encountered. In the past, the surgical instruments were only used for lifting the uterus or only for the separation of drug administration, which was poor adaptability and inconvenient to use, especially in the past. , while the hard straight pendulum lever does not have a soft ball, it is easy to damage the uterine wall, and the operation of swinging the uterus is difficult. The unadjustable position of the cervical pessary and vaginal seal is difficult to adapt to the anatomical relationship between the reproductive system and t...
