[0031] Example 1

[0032] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides an artificial insemination device, which includes an expansion unit 100, including an upper clamp 101, a lower clamp 102 arranged below the upper clamp 101, a movable handle 103 arranged at the bottom of the lower clamp 102, and a torsion spring 104 arranged at a hinge between the upper clamp 101 and the lower clamp 102;

[0033] The insemination unit 200 includes a sperm storage tank 201 disposed on one side of the upper clamp 101 , and a catheter 202 connected to the sperm storage tank 201 .

[0034] Furthermore, the upper clamp 101 includes a first expansion plate 101a, a fixed handle 101b arranged on one side of the first expansion plate 101a, an observation port 101c arranged on the upper surface of the fixed handle 101b, a movable groove 101d arranged on the lower surface of the fixed handle 101b, and a pair of guide rails 101e arranged on both sides of the movable groove 101d.

[0035] Furthermore, the opposing sides of the guide rail 101e are provided with a limiting groove 101e-1.

[0036] Furthermore, the lower clamp 102 includes a second expansion plate 102a, an extension block 102b disposed on one side of the second expansion plate 102a, an arc plate 102c disposed inside the extension block 102b, and a plurality of limiting teeth 102d disposed on the lower surface of the arc plate 102c.

[0037] Furthermore, the two sides of the corners of the lower clamp 102 are hinged to the two side walls of the observation port 101 c; and the two ends of the torsion spring 104 are fixedly connected to the lower clamp 102 and the upper clamp 101 respectively.

[0038] Furthermore, the movable handle 103 includes a hinge groove 103a disposed on the top thereof, and a pulling column 103b disposed on the upper end surface of the movable handle 103;

[0039] The hinge groove 103a includes a limiting wall 103a-1 arranged inside the hinge groove 103a; the bottom of the extension block 102b is hinged to the groove wall of the hinge groove 103a.

[0040] Furthermore, the sperm storage tank 201 includes a tank body 201a and a piston 201b disposed inside the tank body 201a.

[0041] Furthermore, the warehouse body 201a includes a semen collection port 201a-1 arranged on one side thereof, a silicone punching valve 201a-2 arranged on the inner wall of the semen collection port 201a-1, a discharge port 201a-3 arranged at the upper end of the warehouse body 201a, a reflux pipe 201a-4 arranged in the middle of the discharge port 201a-3, a first bent hook plate 201a-5 arranged on one side of the warehouse body 201a, and an open groove 201a-6 arranged at the bottom of the warehouse body 201a.

[0042] Furthermore, the piston 201b includes a push plate 201b-1 arranged on one side thereof, a folding plate 201b-2 arranged at one end of the push plate 201b-1, and a second hook plate 201b-3 arranged at the end of the folding plate 201b-2.

[0043] It should be noted that the upper clamp 101 is mainly composed of a first expansion plate 101a and a fixed handle 101b, the ends of which are fixed together, and an angle is formed between the two, which is an obtuse angle. The cross-sectional shape of the first expansion plate 101a is arc-shaped, and the surface of the outer end is relatively rounded, so the whole presents a plate-like component with an arc. The fixed handle 101b can be convenient for people to hold, and an observation port 101c is provided in the middle position of the upper end of the fixed handle 101b. The observation port 101c can directly observe the situation of the cervical opening in the extension direction of the first expansion plate 101a when the expansion unit 100 opens the reproductive tract. There is also a movable groove 101d connected to the observation port 101c. The movable groove 101d is in the shape of a long strip and extends a distance from the observation port 101c to the bottom of the fixed handle 101b.

[0044] At the bottom of the observation port 101c, on both sides of the movable groove 101d, i.e., on the fixed handle 101b, a pair of guide rails 101e are fixed. The guide rails 101e are symmetrically distributed and extend away from the first expansion plate 101a. A limiting groove 101e-1 is also provided on the opposite side wall of the guide rails 101e. The groove shape of the limiting groove 101e-1 is consistent with the groove shape on both sides of the bin body 201a. Therefore, the outer shape of the bin body 201a can be adapted to the limiting groove 101e-1. In this embodiment, both sides of the bin body 201a are semicircular. The sperm storage bin 201 can be inserted between the guide rails 101e and move axially along the guide rails 101e until it stops at the bottom of the groove. In addition, since the position of the guide rails 101e is at the bottom of the observation port 101c, the sperm storage bin 201 will not block the field of view of the observation port 101c.

[0045] Preferably, the lower clamp 102 is composed of a second expansion plate 102a and an extension block 102b, and the fixing method between the two is consistent with that on the upper clamp 101, and the second expansion plate 102a has the same structure and function as the first expansion plate 101a. The extension block 102b is shorter in length, and a cavity is left inside the extension block 102b, which is connected to the cavity in the second expansion plate 102a. The arc plate 102c can also be fixed at the bottom of the cavity without blocking the doctor's field of vision. The center of the arc plate 102c is at the hinge of the upper clamp 101 and the lower clamp 102. A plurality of circumferentially distributed limiting teeth 102d are provided on the bottom of the arc plate 102c, and the limiting teeth 102d are directly opposite to the sperm storage bin 201. In this embodiment, the limiting teeth 102d are in the shape of a right triangle, and can also be other unidirectional limiting shapes.

[0046] A pair of hinged columns are fixed on both sides of the outermost end of the angle of the lower clamp 102, and hinged holes are opened on the inner walls of the observation port 101c of the upper clamp 101, and the two are hinged. In addition, a torsion spring 104 is provided on the outer wall of each hinged column, one end of the torsion spring 104 is fixedly connected to the inner wall of the observation port 101c, and the other end is fixedly connected to the side wall at the angle of the lower clamp 102, so that the first expansion plate 101a and the second expansion plate 102a are in a closed state.

[0047] Preferably, the movable handle 103 is rod-shaped, with a semi-open hinge groove 103a on the top, and is composed of three side walls, with hinge holes on the two opposite side walls, and the limiting wall 103a-1 is connected to the two side walls. The lower end of the extension block 102b is also fixed with hinge columns on both sides, so the two are hinged, and the limiting wall 103a-1 is located on the side of the guide rail 101e, so the movable handle 103 can rotate with the hinge column as the center of the circle, and when the limiting wall 103a-1 touches the extension block 102b, it is limited. At this time, when a person holds the fixed handle 101b and the movable handle 103, the first expansion plate 101a and the second expansion plate 102a can be opened. When released, the torsion spring 104 forces the first expansion plate 101a and the second expansion plate 102a to close.

[0048] A pulling column 103b is also fixed to the upper end surface of the groove wall of the hinge groove 103a. The pulling column 103b is in the shape of a thin rod and is further lifted upward until it is adjacent to the arc-shaped plate 102c.

[0049] Preferably, the sperm storage bin 201 is used to store sperm suspension, and is composed of a bin body 201a and a piston 201b. In order to facilitate recovery, disassembly and disinfection, a rear cover is clamped at one end of the sperm storage bin 201. There is a cavity in the bin body 201a, and a sperm collection port 201a-1 is fixed at the other end. A detachable silicone punching valve 201a-2 is fixed inside the sperm collection port 201a-1. The silicone punching valve 201a-2 is a prior art and has a check function. When the sperm suspension is sucked from the sperm collection port 201a-1 to the inside of the bin body 201a, the silicone punching valve 201a-2 is only opened on this side, and the liquid cannot pass through when the direction is changed, so it plays a sealing role. In order to ensure the sealing effect, the number can be appropriately increased.

[0050] A discharge port 201a-3 is fixed at the top of the bin body 201a for conveying sperm suspension. Disposing the discharge port 201a-3 at the top can facilitate the access of the catheter 202. A reflux pipe 201a-4 is fixed in the discharge port 201a-3. The reflux pipe 201a-4 is soft and long, and can facilitate the absorption of sperm suspension from the bottom of the bin body 201a.

[0051] At the end face of the bin body 201a facing away from the rear cover, a first hook plate 201a-5 is fixed below the semen taking port 201a-1. The first hook plate 201a-5 extends toward the arc-shaped plate 102c, and at the outermost end of the first hook plate 201a-5 there is a hook that matches the shape of the limiting tooth 102d. When the two cooperate, they can play a one-way limiting role, that is, the first hook plate 201a-5 can slide toward and along the bottom of the arc-shaped plate 102c, and the reverse hook will buckle into the limiting tooth 102d and be limited by the action of the right-angle surface.

[0052] Therefore, when the doctor opens the upper clamp 101 and the lower clamp 102 and controls them in the appropriate position, the warehouse body 201a is pushed into the limiting groove 101e-1 inside the guide rail 101e. At this time, the hook of the first hook plate 201a-5 slides along the limiting tooth 102d until the warehouse body 201a cannot move. The hook will hook the current limiting tooth 102d. When the doctor lets go, the lower clamp 102 cannot be reset and maintains the opening state of the first expansion plate 101a and the second expansion plate 102a. The warehouse body 201a will not fall off under the traction of the arc plate 102c and is in a fixed state.

[0053] It should be noted that since the center of the arc plate 102c is located at the hinge of the upper clamp 101 and the lower clamp 102, at any opening of the first expansion plate 101a and the second expansion plate 102a, the arc plate 102c only rotates circumferentially a small distance, and the position and effect of the limit of the warehouse body 201a will not be affected in any way.

[0054] Preferably, an open slot 201a-6 is provided at the bottom of the housing 201a facing the rear cover. The piston 201b can move axially inside the chamber body 201a, and realize the suction and discharge of sperm suspension by moving. The side wall of the piston 201b is tightly fitted with the inner wall of the chamber body 201a. A push plate 201b-1 is fixed on the end face of the piston 201b facing the rear cover. A folding plate 201b-2 is fixed on the outer end of the push plate 201b-1. The folding plate 201b-2 consists of two parts, a downward part and an oblique part. The shorter the vertical distance of the folding plate 201b-2, the weaker the deformation effect caused by the lateral force. The oblique folding plate 201b-2 directly leads to the position adjacent to the pulling column 103b. A second hook plate 201b-3 is also fixed at the end of the oblique folding plate 201b-2. A hook is provided at the outermost end of the second hook plate 201b-3. The hook can hook the pulling column 103b and prevent dislocation. Therefore, the movable handle 103 can control the injection of the sperm suspension by swinging the control piston 201b, while the folding plate 201b-2 can move along the open groove 201a-6 without interference.

[0055] When performing artificial insemination, the pulling column 103b is first placed between the extension block 102b and the second hook plate 201b-3. This is pre-adjustment. At this time, the first expansion plate 101a and the first expansion plate 101a are in a closed state.

[0056] First, the upper clamp 101 and the lower clamp 102 are inserted into the reproductive tract, and then the doctor holds the fixed handle 101b and the movable handle 103. At this time, due to the effect of the limiting wall 103a-1, the first expansion plate 101a and the first expansion plate 101a are opened, and then the appropriate opening degree is controlled.

[0057] Next, the sperm storage bin 201 filled with sperm suspension is inserted into the rear guide rail 101e until the first bent hook plate 201a-5 hooks the limiting tooth 102d. At this time, the lower clamp 102 and the sperm storage bin 201 are limited to each other, and while maintaining the opening of the first expansion plate 101a and the first expansion plate 101a, the sperm storage bin 201 is also fixed.

[0058] Then, the movable handle 103 is slightly rotated in the opposite direction, at which time the pulling column 103b will push and pass over the second hook plate 201b-3, so that the pulling column 103b is in a position where the second hook plate 201b-3 faces the rear cover of the sperm storage bin 201.

[0059] Subsequently, the catheter 202 is inserted into the uterine cavity through the observation port 101c, and the other end of the catheter 202 is connected to the semen collection port 201a-1.

[0060] Finally, pressing the movable handle 103 can drive the piston 201b and inject the sperm suspension.

[0061] In summary, the device completes the process of opening the reproductive tract and injecting sperm suspension only through the operation of the movable handle 103, which reduces the frequency of operating different equipment, and most steps can be operated with one hand. At the same time, the device has high integration and convenient operation, which reduces the doctor's repeated actions of picking up different equipment, simplifies the traditional operation process, saves operation time, and reduces the risk of the recipient being exposed to equipment left in the body.

[0062] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
