Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for egg retrieval, and in particular to a puncture and egg retrieval positioning device for assisted reproductive egg retrieval procedures. Background Technology

[0002] The egg retrieval procedure requires the use of an egg retrieval needle to extract the eggs. The needle is 35cm long in total, but only 10cm is inserted into the body, with a longer portion remaining outside the body. During the procedure, the doctor needs to ensure that the needle does not wobble at all. Prolonged operation can easily lead to hand fatigue for the doctor. After the egg retrieval is completed, pressure needs to be applied to the puncture site to stop the bleeding. After the needle is removed, the doctor needs to re-identify the puncture site before applying pressure to stop the bleeding, which causes inconvenience for medical staff. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a puncture and positioning device for assisted reproductive egg retrieval. This invention uses an auxiliary insertion mechanism to finely adjust the insertion angle of the egg retrieval needle, ensuring that the needle is accurately inserted into the designated position. Simultaneously, it supports the needle, facilitating the doctor's operation and preventing the needle from shaking during operation. After the needle is removed, hemostasis is achieved by pressing the hemostasis mechanism at the puncture site, reducing the time required to re-determine the puncture site.

[0004] To achieve the aforementioned objective, the present invention employs the following technical solution: A puncture and positioning device for assisted reproductive oocyte retrieval includes a positioning mechanism, a height adjustment mechanism installed on the movable end of the positioning mechanism, an auxiliary insertion mechanism installed on the adjustment end of the height adjustment mechanism, and a pressure hemostasis mechanism installed on the fixed end of the auxiliary insertion mechanism.

The third screw is rotatably connected to the movable block and is located between the two sliding rods. The movable frame is mounted on the third screw and the sliding rods, and an auxiliary insertion mechanism is mounted on the top of the movable frame. A limiting plate is mounted on one end of the third screw and the sliding rod inside the movable frame.

[0007] The auxiliary insertion mechanism includes a main cylinder, a movable plate, a drive frame, a fourth screw, a fifth screw, an insertion tube, and a connecting block. The main cylinder is located on the movable frame and is fixedly connected. An equidistantly arranged positioning rod is fixedly connected to the inner wall of one end of the main cylinder.

Detailed Implementation

[0016] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] The height adjustment mechanism 2 includes a third screw 201, a sliding rod 202, a movable frame 203, and a limiting plate 204. There are two sliding rods 202, both of which are located on the movable block 103 and fixedly connected. The third screw 201 is rotatably connected to the movable block 103 and is located between the two sliding rods 202. The movable frame 203 is installed on the third screw 201 and the sliding rod 202, and an auxiliary insertion mechanism 3 is installed at the top of the movable frame 203. The limiting plate 204 is installed at one end of the third screw 201 and the sliding rod 202 inside the movable frame 203.

[0020] The auxiliary insertion mechanism 3 includes a main body cylinder 301, a movable plate 302, a drive frame 303, a fourth screw 304, a fifth screw 305, an insertion tube 306, and a connecting block 307. The main body cylinder 301 is located on the movable frame 203 and is fixedly connected. A positioning rod is fixedly connected to the inner wall of one end of the main body cylinder 301 at equal intervals. A rubber ring is fixedly connected between the positioning rods, and the insertion tube 306 is installed inside the rubber ring. The fourth screw 304 is threadedly connected to the end of the main body cylinder 301 away from the positioning rod. The drive frame 303 is rotatably connected to the end of the fourth screw 304 located inside the main body cylinder 301. The fifth screw 305 is rotatably connected inside the drive frame 303, and the movable plate 302 is threadedly connected to the fifth screw 305. The movable plate 302 is connected to the insertion tube 306 through the connecting block 307.

[0021] The main body cylinder 301 is provided with a sliding groove, and the position of the sliding groove corresponds to the position of the fifth screw 305.

[0022] The main body cylinder 301 has an installation groove on its cylinder wall away from the slide groove, and a pressing hemostasis mechanism 4 is installed in the installation groove.

[0023] The pressure hemostasis mechanism 4 includes a limiting rod 401, an L-shaped push rod 402, a sliding rod 403, a limiting block 404, a pressing rod 405, a sliding block 406, and a displacement block 407. The limiting rod 401 is located in the mounting groove and is fixedly connected, and the displacement block 407 is slidably connected to the limiting rod 401. The L-shaped push rod 402 is installed on the displacement block 407, and the sliding rod 403 is slidably connected to the longitudinal end of the L-shaped push rod 402. The limiting block 404 is fixedly connected to the sliding rod 403, and the limiting block 404 is slidably connected to the insertion tube 306. The sliding block 406 is installed inside the limiting block 404, and the pressing rod 405 is fixedly connected to the limiting block 404. A sterile cotton ball can be installed on the pressing rod 405.

[0024] A rotating rod is rotatably connected to the displacement block 407, and the displacement block 407 is connected to the L-shaped push rod 402 through the rotating rod.

[0025] The limiting block 404 is provided with a sliding groove and a through groove, and the sliding groove and the through groove are interconnected. An insertion tube 306 is slidably connected in the through groove. A sliding block 406 is slidably connected in the sliding groove, and a return spring is fixedly connected to the sliding block 406. The other end of the return spring is fixedly connected to the groove wall of the sliding groove. The side of the sliding block 406 that contacts the end of the insertion tube 306 is an inclined surface.

[0026] After the sliding block 406 moves to its maximum distance, the pressing rod 405 on the sliding block 406 will coincide with the insertion tube 306, eliminating the need for medical personnel to re-determine the puncture site.

[0027] The described puncture and positioning device for assisted reproductive egg retrieval involves the doctor securing a U-shaped frame 101 to the bed and fixing it in place using a second screw 105. A third screw 201 adjusts the height of a movable frame 203, aligning the auxiliary insertion mechanism 3 on the movable frame 203 with the puncture site. The doctor fine-tunes the insertion angle of the insertion tube 306 based on the ultrasound image. A fourth screw 304 adjusts the height of one end of the insertion tube 306, and a fifth screw 305 adjusts the lateral position of one end of the insertion tube 306, ensuring that one end of the insertion tube 306 is aligned with the area to be punctured. In this position, the doctor inserts the egg retrieval needle into the insertion tube 306 to retrieve the eggs. After egg retrieval, the doctor pulls out the egg retrieval needle with one hand and pushes the L-shaped push rod 402 with the other hand to move the L-shaped push rod 402. During the movement of the L-shaped push rod 402, it will drive the limiting block 404 to move. When the sliding block 406 in the limiting block 404 is disengaged from the insertion tube 306, the return spring in the limiting block 404 will push the sliding block 406 to move, so that the pressing rod 405 of the sliding block 406 will coincide with the position of the insertion tube 306. The staff will drive the pressing rod 405 to move through the first screw 102 and press the puncture site with the pressing rod 405 to stop bleeding.
