Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of egg retrieval devices, and more specifically, to an egg retrieval device. Background Technology
[0002] An egg retrieval device is a medical device that involves inserting a needle into the ovary to collect the eggs.
[0003] However, existing egg retrieval devices use two separate tubes for fluid injection and egg retrieval during the process. These two tubes are designed to be separate, so when using different tubes, it is necessary to connect the air pressure tube to the different tubes from time to time. Because the tubes are designed to be separate, they are easy to get tangled during the alternating operation, which can lead to blockage of the tubes and require untangling, thus affecting the efficiency of egg retrieval. Utility Model Content
[0004] The purpose of this invention is to provide an egg retrieval device that solves the problem that the two flexible tubes of the egg retrieval device are easily entangled during use when they are used in an alternating manner because they are set separately, thus affecting the egg retrieval efficiency.

[0006] This utility model provides an egg retrieval device, including an egg retrieval needle, a connecting tube at one end of the egg retrieval needle, a connecting hose at one end of the connecting tube, a connecting pipe at one end of the connecting hose, a communicating vessel at one end of the connecting hose, a collection container at the bottom of the communicating vessel, a communicating cavity on one side of the communicating vessel, a pressure pipe connected to the middle of the communicating cavity, and limit components on both sides of the middle of the communicating cavity, the limit components swinging along an axis.
[0007] Preferably, the communicating cavity further includes a connecting opening, which is located on one side of the middle of the communicating cavity.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0015] 1. The communicating vessel in this device can integrate two connecting hoses into one unit, allowing them to be directly connected on a single structure. This avoids the need for separate hoses when using different hoses, preventing entanglement and ensuring efficient egg retrieval.

Detailed Implementation
[0021] The following is combined Figures 1 to 3 This utility model will be described in detail.
[0022] An egg retrieval device includes an egg retrieval needle 1, a connecting tube 101 at one end of the egg retrieval needle 1, a connecting hose 102 at one end of the connecting tube 101, a connecting pipe 1021 at one end of the connecting hose 102, a communicating vessel 2 at one end of the connecting hose 102, a collection container 201 at the bottom of the communicating vessel 2, a communicating cavity 203 on one side of the communicating vessel 2, a pressure pipe 202 connected to the middle of the communicating cavity 203, and limit components on both sides of the middle of the communicating cavity 203, the limit components swinging along an axis.
[0023] First, the oocyte retrieval needle 1 is inserted into the ovary. Then, washing fluid is injected into one of the connecting tubes 102 through the air pressure tube 202 to flush and disperse the oocytes. Next, the other connecting tube 102 is aspirated through the air pressure tube 202 to draw the oocytes into the connecting tube 102 and then into the collection container 201 for collection. At the same time, the oocyte retrieval needle 1 is equipped with a separate channel to connect the two connecting tubes 102 to complete the oocyte sampling.
[0024] Furthermore, the connecting cavity 203 also includes a connecting opening 2031, which is located on one side of the middle portion of the connecting cavity 203. The connecting opening 2031 is an opening on one side of the middle portion of the connecting cavity 203 that mates with the connecting pipe 1021.
[0025] When connecting the two connecting hoses 102 using the pneumatic tube 202, the connecting pipes 1021 of both connecting hoses 102 are connected to the connecting opening 2031 of the communicating vessel 2, preventing the two connecting hoses 102 from separating. This ensures that the connecting pipes 1021 are both within the communicating cavity 203, and the pneumatic tube 202 is fitted into the communicating cavity 203. By simply sliding the pneumatic tube 202 to both ends within the communicating cavity 203, it can be aligned with the corresponding connecting pipe 1021 and docked with the connecting hose 102. This allows flushing and extraction to be performed in one device, eliminating the need to handle the connecting hoses 102 when docking different connecting hoses 102, thus preventing the connecting hoses 102 from becoming entangled during operation.
[0026] Furthermore, the limiting component includes a fitting groove 204, a deflecting rod 2041, a hinge shaft 2042, and a limiting ball 2043. The fitting groove 204 is located on both sides of the middle part of the communicating cavity 203. The deflecting rod 2041 is connected in the fitting groove 204. The hinge shaft 2042 is located at one end of the deflecting rod 2041. The limiting ball 2043 is located on both sides of the middle part of the fitting groove 204. The fitting groove 204 is located on both sides of the middle part of the communicating cavity 203 near the opening. The deflecting rod 2041 is L-shaped, and the bent part of the deflecting rod 2041 is connected to the fitting groove 204 through the hinge shaft 2042. The thickness of the deflecting rod 2041 is less than that of the fitting groove 204. The limiting ball 2043 is a hemispherical protrusion located on both sides of the middle part of the fitting groove 204 near the opening. Several limiting balls 2043 are arranged vertically.
[0027] Meanwhile, deflection rods 2041 are provided on both sides of the connecting cavity 203 near the opening and near both ends. When the air pressure pipe 202 moves to one end of the connecting cavity 203 and connects to one of the connecting hoses 102, the air pressure pipe 202 will apply pressure to the protruding part of the deflection rod 2041 during the sliding process, forcing the deflection rod 2041 to deflect along the hinge axis 2042 and fit into the fitting groove 204, so that the air pressure pipe 202 can move smoothly to one end of the connecting cavity 203. During the deflection of the deflection rod 2041, due to the "L" shape, the other side will deflect out from the fitting groove 204 and abut against one side of the air pressure pipe 202, so that the air pressure pipe 202 is kept in a certain limited connection at one end of the connecting cavity 203, making it more stable during suction or injection.
[0028] Finally, when the deflecting rod 2041 deflects and engages into the engagement groove 204, the deflecting rod 2041 will squeeze past the limiting ball 2043. The limiting ball 2043 will limit the deflecting rod 2041 to a certain extent, thereby limiting the air pressure pipe 202 and increasing the accuracy of the air pressure pipe 202 when it is quickly displaced and connected.
[0029] The following is a detailed implementation process of this utility model: First, the oocyte retrieval needle 1 is inserted into the ovary. Then, washing fluid is injected into one of the connecting tubes 102 through the air pressure tube 202 to flush and disperse the eggs. Next, the air pressure tube 202 is used to aspirate the other connecting tube 102, drawing the eggs into the connecting tube 102 and then into the collection container 201 for collection. The oocyte retrieval needle 1 has a separate channel to connect the two connecting tubes 102 for oocyte sampling. When connecting the two connecting tubes 102 through the air pressure tube 202, the connecting tubes 1021 of both connecting tubes 102 are connected to the connecting opening 2031 of the communicating vessel 2, preventing the two connecting tubes 102 from separating. This ensures that the connecting tubes 1021 are both within the communicating cavity 203, and the air pressure tube 202 is fitted into the communicating cavity 203. The air pressure tube 202 then allows for simple... Sliding to both ends, it can be aligned with the corresponding connecting pipe 1021 and connected to the connecting hose 102, allowing flushing and extraction to be performed in one device. At the same time, deflecting rods 2041 are provided on both sides of the connecting cavity 203 near the opening and near both ends. When the air pressure pipe 202 moves to one end of the connecting cavity 203 and connects with one of the connecting hoses 102, the air pressure pipe 202 will apply pressure to the protruding part of the deflecting rod 2041 during the sliding process, forcing the deflecting rod 2041 to deflect along the hinge axis 2042 and fit into the fitting groove 204, allowing the air pressure pipe 202 to move smoothly to one end of the connecting cavity 203. During the deflection of the deflecting rod 2041, due to the "L" shape, the other side will deflect out from the fitting groove 204 and abut against one side of the air pressure pipe 202, keeping the air pressure pipe 202 in a certain limited connection at one end of the connecting cavity 203, making it more stable during suction or injection.
