[0002] The egg retrieval operation involves inserting a needle into the ovary through the vagina, so the egg retrieval operation will be painful. Currently, hospitals will anesthetize the person who is retrievaling the eggs, and the operation may be painful but bearable. Because everyone's perception of pain is different, most people think that retrieving one or two eggs is bearable and will not be as painful as a miscarriage or fallopian tube angiography. Therefore, the pain varies from person to person. The person who is retrievaling the eggs lies on a bed, and the vulva and vagina are disinfected, with sterile towels placed outside. The doctor inserts an ultrasound probe with a puncture needle into the vagina, punctures the ovary through the dome, and aspirates the follicular fluid.

[0003] Flushing needle means that before the egg retrieval operation, the nurse must hold a test tube filled with culture medium, and the surgeon will turn on the negative pressure suction device, hold the egg retrieval needle, and place the needle tip into the test tube to absorb the culture medium to test the patency of the egg retrieval needle and the extension tube. After the operation, when the egg retrieval needle is pulled out, the culture medium needs to be absorbed to flush the tube wall to prevent follicular fluid and eggs from remaining. However, due to the small diameter of the test tube and the long length of the egg retrieval needle, the needle tip is prone to shaking. During the flushing needle operation, the nurse is prone to needle stick injuries. Utility Model Content

[0016] In order to facilitate the use of the connecting belt 2, a Velcro is provided on the side of the connecting belt 2 away from the base 1, and a Velcro sub-tape is provided at the free end of the connecting belt 2 that can be adhered to the Velcro. A fixing ring 8 is fixed at the front end of the base 1, and the connecting belt 2 can pass through the fixing ring 8. An elastic pad 9 is provided at the right end of the base 1.

[0017] In order to facilitate the clamping of the splint 3, a guide block is slidably connected to the base 1, and a screw 10 is rotatably connected to the right side of the guide block. The threads on the upper and lower sides of the screw 10 rotate in opposite directions and are threadedly connected to the splint 3 on the corresponding side. The upper end of the screw 10 passes through the splint 3 and is provided with a handle 11.

[0018] In order to facilitate the movement of the screw rod 10 and the clamping plate 3, a clearance groove 12 is opened on the base 1, and the upper and lower sides of the right end of the clearance groove 12 are connected to the outside.

[0019] In order to increase the damping of the rotation of the sphere 6, the damping component includes a left and right axial moving block 13. The moving block 13 is located to the right of the sphere 6 on its corresponding side and is slidably connected to the fixed block 4. A groove is provided at the left end of the moving block 13, and a damping pad 14 is fixed in the groove, which can fit the outer surface of the sphere 6.

[0020] In order to facilitate the control of the movement of the moving block 13 , the fixed block 4 is rotatably connected to a left and right axial rotating block 15 , and the rotating block 15 is threadedly connected to the moving block 13 .
