Description

Technical Field

[0001] The invention relates to the field of animal husbandry, and in particular to a directional egg collection and automatic replacement collection kit for livestock. Background Art

[0002] The operation of ovarian egg retrieval from livestock is a scientific means for livestock to achieve large-scale breeding and farming in the field of livestock breeding and research. Therefore, this operation is of great significance. When conducting scientific research on breeding, egg retrieval is also an operation that experimental operators need to perform frequently. Livestock with larger ovaries such as pigs and cattle generally use a 26G ordinary syringe to directly puncture the 3-8mm follicles and extract the follicular fluid and eggs into the syringe for subsequent operations. When conducting a large number of egg collection experiments, dozens or even hundreds of ovaries need to be processed in a short period of time. The method of using a syringe to retrieve eggs is itself inefficient. In addition, when the ovaries leave the body of the livestock, in order to ensure the survival rate of the livestock egg cells, the egg retrieval operation needs to be performed quickly.

[0003] At present, in the traditional egg retrieval operation, a vaginal ultrasound probe is inserted into the vagina of livestock, and the vaginal ultrasound probe is manually operated to push up the inner wall of the vagina at an angle. The more the front end of the vaginal ultrasound probe pushes outward and protrudes, the easier it is to detect the specific position of the ovary. Then the egg retrieval needle is operated to puncture the ovary in the oblique direction of the vaginal ultrasound probe to extract eggs. This operation can successfully extract eggs, but it has the following defects:

[0004] 1. When the vaginal ultrasound probe is tilted inside the vagina, it cannot be effectively fixed in an oblique position. The operator can only manually control the front ball head of the vaginal ultrasound probe frame to obliquely lift the vaginal wall to explore the ovarian position. When the vaginal ultrasound probe frame is tilted, the greater the tilt of the rear end is, the more likely it is to tear the livestock's vagina. At the same time, manually controlling the overall tilt of the vaginal ultrasound probe frame in the livestock's vagina cannot effectively ensure that the vaginal ultrasound probe frame is always in a stable tilt angle when the egg retrieval needle is inserted after the ovarian position is located.

[0005] 2. There is no effective guiding structure to guide the puncture direction of the egg retrieval needle during the process of entering the ovary through vaginal puncture. It is very easy for the puncture position to deviate due to hand shaking, resulting in the wrong puncture position. The traditional method takes a long time and requires high skills from the operator, which can easily cause soreness in the operator's hands. In addition, re-puncture due to the wrong puncture position will cause unnecessary damage to the health of livestock.

[0006] 3. During large-scale collection, the collection tubes are scattered radially. Each time the collection tubes are replaced, the collection tubes that have been collected need to be placed properly. At the same time, when replacing the plug and ensuring airtightness, the plug is often not effectively tightened, resulting in leakage, etc., making it impossible to form an effective negative pressure environment inside the collection tube to perform negative pressure suction on the eggs inside the follicles.

The rotating power member is connected to the rotating shaft Ⅰ 23 by transmission. The rotating shaft Ⅱ 24 is hinged to the shift fork 10. The limited guide groove 22 is sleeved on the guide slide rod structure 11. The U-shaped groove 21 is intermittently sleeved on the cylindrical pin 20. The rotating power member drives the shift fork 10 to perform a crank-connecting rod motion and drives the turntable Ⅱ 8 to rotate intermittently.

[0050] A number of collection test tubes 13 are evenly arranged circumferentially on the turntable Ⅰ12, and a clamping power member, a negative pressure box 17, and a flushing box 19 are arranged on the platform 7. The clamping power member is raised and pressed down to control the conical plug 14 to plug the collection test tube 13; one end of the egg extraction tube 15 passes through the conical plug 14 and is connected to the collection test tube 13, and the other end is connected to the egg collection chamber 5; one end of the negative pressure extraction tube 16 passes through the conical plug 14 and is connected to the collection test tube 13, and the other end is connected to the negative pressure box 17; the flushing tube 18 is connected between the flushing box 19 and the flushing chamber 6.

[0052] Preferably, the set also includes: a heat-insulating shielding shell 25, an arc-shaped baffle 26, a driving turntable 27, and a movable handle 28; the heat-insulating shielding shell 25 is a circular hollow structure, and an arc-shaped baffle groove 29 is provided on the heat-insulating shielding shell 25; one of the two ends of the arc-shaped baffle 26 is provided with a sliding pin 30 on the upper end face, and a rotating pin 31 is provided on the lower end face; a plurality of arc-shaped baffles 26 are stacked in a circle in the arc-shaped baffle groove 29, and the rotating pin 31 of the arc-shaped baffle 26 is hinged to the lower end of the arc-shaped baffle groove 29, and a sliding groove 32 running in a radial direction is provided at the position of the sliding pin 30 on the upper end face of the arc-shaped baffle 26 on the driving turntable 27, and the sliding pin 30 is sleeved in the sliding groove 32, and a rotating groove 33 is provided on the heat-insulating shielding shell 25, and the movable handle 28 is penetrated by the rotating groove 33 and connected with the driving turntable 27.

[0053] The outer circumference of the hexagonal turntable Ⅰ12 on the upper end face of the platform 7 is covered with a heat-insulating shielding shell 25. The heat-insulating shielding shell 25 is a circular annular sleeve with a certain ring wall thickness, and a large circular hollow penetration area in the middle. The heat-insulating shielding shell 25 is composed of a baffle layer 35 and a heat-insulating layer 39. The inner arc wall of the baffle layer 35 of the heat-insulating shielding shell 25 is opened inward with an arc-shaped baffle groove 29 of a certain depth and a certain width. A plurality of arc-shaped baffles 26 (six groups of arc-shaped baffles 26 are provided in this set) are evenly distributed and hinged in the circumference of the arc-shaped baffle groove 29 of the baffle layer 35. The arc-shaped baffle 26 is in an arc shape as a whole, and its width is consistent with the width of the arc-shaped baffle groove 29 and its thickness is relatively thin. A sliding pin 30 is provided on one upper end surface of both ends of the arc-shaped baffle 26, and a rotating pin 31 is provided on one lower end surface. The six groups of arc-shaped baffles 26 are stacked one after another in a circle in the arc-shaped baffle groove 29, and each adjacent group of arc-shaped baffles 26 overlaps and stacks a certain area below the sliding pin 30 of the arc-shaped baffle 26 of the previous group. The rotating pins 31 on the lower end surfaces of the front ends of the six groups of arc-shaped baffles 26 are all hinged to the lower end of the arc-shaped baffle groove 29. A driving turntable 27 is provided between the upper end surfaces of the six groups of arc-shaped baffles 26 and the upper end surfaces of the arc-shaped baffle grooves 29. A radially extending sliding groove 32 is provided on the driving turntable 27 at the position of the sliding pin 30 corresponding to the upper end surface of the arc-shaped baffle 26. The width of the sliding groove 32 matches the outer diameter of the sliding pin 30, so that the sliding pin 30 can be placed inside the sliding groove 32. The sliding groove 32 has a certain length in the radial direction, so that the sliding pin 30 can slide inside the sliding groove 32.

[0054] A movable handle 28 extending outward is integrally provided on one side of the outer end of the driving turntable 27, and a rotation groove 33 of a certain arc length is provided on the outer wall of the heat preservation shielding shell 25 corresponding to the area of ​​the movable handle 28. The arc of the rotation groove 33 can enable the movable handle 28 to drive the driving turntable 27 to rotate a certain angle. In addition, because the rotation pin 31 at the lower end of the arc-shaped baffle 26 is hinged on the heat preservation shielding shell 25, and the upper end sliding pin 30 can slide radially inside the sliding groove 32 of the driving turntable 27, when the driving turntable 27 rotates, the arc-shaped baffle 26 can be driven to rotate in the axial direction.

[0055] The rotating groove 33 of the heat-insulating shielding shell 25 has a certain angle limiting effect on the movable handle 28 of the driving turntable 27. When the movable handle 28 is moved to the initial end, the driving turntable 27 drives the arc-shaped baffle 26 to retract into the arc-shaped baffle groove 29, and will not block the middle circular hollow area of ​​the heat-insulating shielding shell 25. At this time, the tube mouth of the collection test tube 13 is in an uncapped and unblocked state. When the movable handle 28 is moved to the other end of the rotating groove 33, the driving turntable 27 drives the arc-shaped baffle 26 to rotate to have the maximum radial length shielding effect on the circular hollow area. This state can play a capping and blocking role on the tube mouth of the collection test tube 13. A fixed handle 34 is integrally provided radially outward on the outer wall of the baffle layer 35 at the same height on the other side of the rotating groove 33. With the fixed handle 34, it is more convenient to control the movable handle 28 to drive the rotation of the driving turntable 27.

A power box 36 is embedded and fixed inwardly on the outer wall of the heat-insulating layer 39, and the power box 36 located in the circumferential annular cavity is connected to a heat-insulating pipe 37, and the heat-insulating pipe 37 is spirally coiled in the circumferential annular cavity of the heat-insulating layer 39 at the vertical height of the entire circumferential annular cavity. At the same time, the circumferential annular cavity is filled with heat-insulating fillers 38, which play the role of isolating the temperature of the outer circumferential wall of the heat-insulating layer 39 and transferring heat to the circumferential inner wall. A switch is provided on the outside of the power box 36, and the opening and closing of the heat-insulating pipe 37 can be controlled by the switch.

[0058] Preferably, the worm and worm gear assembly includes: a worm 41, a worm rotating rod 42, a knob 43, a worm wheel 44, and a connecting rod 45; a hollow groove 46 is opened at the end of the vaginal ultrasound probe frame 1, and a worm 41 is hingedly arranged at the axial position of the vaginal ultrasound probe frame 1 inside the hollow groove 46, and the worm 41 is coaxially connected to the worm rotating rod 42, and the worm rotating rod 42 extends inside the vaginal ultrasound probe frame 1 and extends out to be connected to the knob 43, and the worm rotating rod 42 is a metal soft rod.

The front section has a thinner outer diameter and a longer axial length of the access section, and the rear section has a thicker outer diameter and a shorter axial length of the handle section. There are empty grooves 46 on both sides of the front end of the vaginal ultrasound probe frame 1 from the outer wall to the inside. A worm 41 is hinged at the axis position of the vaginal ultrasound probe frame 1 inside the empty groove 46. A worm rotating rod 42 is coaxially fixed at the rear end of the worm 41. The worm rotating rod 42 extends backward inside the vaginal ultrasound probe frame 1 to the rear end of the vaginal ultrasound probe frame 1, and a knob 43 is coaxially connected at the rear end of the worm rotating rod 42. The worm rotating rod 42 is a metal soft rod with a certain thickness and has the characteristics of bending and deformation. When the knob 43 is controlled to drive the worm rotating rod 42 to rotate, the worm 41 at the front end can be rotated synchronously. Worm wheels 44 are symmetrically arranged on both sides of the worm 41 to mesh with the worm 41. The worm wheels 44 are hinged inside the empty slot 46. When the worm 41 rotates, the worm wheels 44 on both sides can be driven to rotate synchronously at the same angle. A probe flap 2 is fixedly connected to the outside of the worm wheel 44 through a connecting rod 45. The probe flap 2 can play a role in ultrasonic positioning of the ovary 81 inside the vagina.

[0062] The probe flaps 2 fixed by the connecting rods 45 on the left and right worm gears 44 are also symmetrically distributed.

An ultrasonic probe is arranged at the front end of the probe flap 2. When the two probe flaps 2 rotate, the position of the corresponding ovary 81 can be confirmed through the probe flap 2. The middle position of the probe flap 2 is designed to be made of silicone material, and the egg retrieval needle 3 can penetrate the middle position of the probe flap 2, thereby passing through the probe flap 2 to perform the egg retrieval operation. Two puncture guide channels 4 are symmetrically arranged at symmetrical positions on both sides of the access section of the vaginal ultrasound probe frame 1. The puncture guide channels 4 have two symmetrical channel entrances 47 in the direction of the two probe petals 2 at the rear position of the access section of the vaginal ultrasound probe frame 1, and the puncture guide channels 4 inside the channel entrances 47 are symmetrically opened in the direction of the other side and forwardly obliquely, so that the puncture guide channels 4 corresponding to the channel entrance 47 on the left side of the vaginal ultrasound probe frame 1 have a channel exit 48 on the front right wall, and the puncture guide channels 4 corresponding to the channel entrance 47 on the right side have a channel exit 48 on the front left wall, and the two puncture guide channels 4 are in a crossed X-shaped direction. Because the puncture guide channels 4 pass through the central axis area of ​​the vaginal ultrasound probe frame 1, the worm rotating rod 42 has a certain bending and giving way on its side when it corresponds to the puncture guide channels 4 to prevent interference with the puncture guide channels 4. When the two probe petals 2 are opened, the egg retrieval needle 3 is inserted through the puncture guide channel 4, and the egg retrieval needle 3 can penetrate the silicone layer area in the middle of the probe petals 2, and finally accurately reach the position of the follicle 82 inside the ovary 81, and perform the egg extraction operation. A round convex head 49 is arranged at the center of the front end face of the vaginal ultrasound probe frame 1. The round convex head 49 is a convex spherical head used to fill the entrance in the middle of the cervix 80 when the vaginal ultrasound probe frame 1 is extended and guided to reach the position of the cervix 80. A data line 83 is arranged on the handle section on the rear side of the vaginal ultrasound probe frame 1 for internal ultrasonic detection operation and development connection.

[0064] The egg retrieval needle 3 can be inserted into the puncture guide channel 4. The egg retrieval needle 3 includes a needle core 50, a needle seat 51, and a connecting tube at the rear end. The egg retrieval needle 3 in this set is designed as a double-chamber structure, wherein the large chamber is the egg retrieval chamber 5, and the small chamber is the flushing chamber 6. The flushing chamber 6 is used to repeatedly flush the follicles 82 during egg retrieval to ensure the activity of the follicles 82 and improve the egg retrieval rate. The needle seat 51 fixedly connected to the rear end of the needle core 50 is a three-way structure, with a main joint at the rear end and a secondary joint on the side. The main joint is connected to the egg extraction tube 15, and the secondary joint is connected to the flushing tube 18. The flushing tube 18 and the egg extraction tube 15 are both connected to the egg negative pressure suction structure backward.

A hexagonal turntable is set on the upper and lower end faces of the center position of the platform 7. The two hexagonal turntables are coaxially fixedly connected. The upper one of the platform 7 is a hexagonal turntable Ⅰ12, and the lower one is a hexagonal turntable Ⅱ8. The specifications of the two hexagonal turntables are consistent. The hexagonal turntable has six radially divergent extension arms. The angle between the two adjacent extension arms is 60 degrees, and the extension length of each extension arm is the same. A cylindrical pin 20 with a certain diameter and height is vertically fixed at the end of the lower end face of the six extension arms of the hexagonal turntable Ⅱ8. A fixed column 56 is fixed vertically downward at the edge of the lower end face of the platform 7. A fixed rod 57 is horizontally fixedly connected to the lower end port of the fixed column 56. The other end of the fixed rod 57 extends to the center of the platform 7. A synchronous pulley Ⅰ53 is coaxially hinged on the upper end surface of the end of the fixed rod 57, and a motor Ⅰ52 is fixed on the edge position of the other side of the lower end surface of the platform 7. A synchronous pulley Ⅱ54 is coaxially fixedly connected to the lower end of the motor Ⅰ52. The synchronous pulley Ⅱ54 and the synchronous pulley Ⅰ53 have the same vertical height and the same specifications. A synchronous belt 55 is sleeved on the synchronous pulley Ⅰ53 and the synchronous pulley Ⅱ54, and the synchronous belt 55 can make the synchronous pulley Ⅰ53 and the synchronous pulley Ⅱ54 rotate synchronously. The axial position of the synchronous pulley Ⅰ53 is fixedly connected to one end of the rotating rod 9 above it through the rotating shaft Ⅰ23, and the upper end surface of the other end of the rotating rod 9 is hingedly connected to the upper fork 10 through the rotating shaft Ⅱ24. The fork 10 as a whole is composed of two layers of upper and lower rods with a certain thickness. The two layers of rods have the same orientation and are fixedly connected at the rotating shaft Ⅱ24. A U-shaped groove 21 is designed inward at the other end of the upper layer of the rod, and an oblong limiting guide groove 22 is designed at the other end of the lower layer of the rod along the orientation direction. The limiting guide groove 22 passes through the upper and lower end surfaces of the lower layer of the rod.

[0067] Preferably, the guide slide rod structure 11 includes: a fixed seat 58, a rotating shaft seat 59, a rotating piece I60, a supporting partition 61, a rotating piece II62, a guide round rod I63, and a guide round rod II64; the guide slide rod structure 11 is connected to the lower end surface of the platform 7 through the fixed seat 58, the rotating piece I60 is hinged to the fixed seat 58 through the rotating shaft seat 59, the rotating piece I60 is connected to the rotating piece II62 through the supporting partition 61, and the guide round rod I63 and the guide round rod II64 are symmetrically arranged on both sides of the supporting partition 61 and hinged between the rotating piece I60 and the rotating piece II62.

[0068] A guide slide rod structure 11 is fixed on the lower end surface of the platform 7 on one side of the outer periphery of the hexagonal turntable Ⅱ8, and the bottom of the guide slide rod structure 11 is fixed to the lower end surface of the platform 7 through a fixed seat 58. A rotating piece Ⅰ60 arranged below the fixed seat 58 is hinged to the fixed seat 58 through a rotating shaft seat 59, and the rotating piece Ⅰ60 is fixedly connected to the rotating piece Ⅱ62 through a supporting partition 61 below. Guide round rods Ⅰ63 and guide round rods Ⅱ64 are symmetrically arranged on both sides of the supporting partition 61 and are hinged between the rotating piece Ⅰ60 and the rotating piece Ⅱ62. The guide round rods Ⅰ63 and guide round rods Ⅱ64 are sleeved in the limiting guide groove 22 of the fork 10, and the two guide round rods are respectively fitted with the two side surfaces inside the corresponding limiting guide groove 22 to cooperate with each other to play a guiding role. At the same time, the two guide round rods that are respectively hinged and can flexibly rotate respectively play a role in reducing friction stress on the rolling friction of the two side surfaces of the limiting guide groove 22 with different linear speeds, so that the guidance can be smoother and there will be no clamping and fixing phenomenon.

[0069] When the motor Ⅰ52 is turned on to drive the synchronous pulley Ⅱ54 and the synchronous pulley Ⅰ53 to rotate synchronously, the synchronous pulley Ⅰ53 drives the rotating shaft Ⅰ23 to drive the rotating rod 9 to rotate synchronously through the rotating shaft Ⅰ23, and the rotating rod 9 drives the rotating shaft Ⅱ24 at the other end to perform circular motion. Because the rotating plate Ⅰ60 and the rotating plate Ⅱ62 can rotate synchronously, they can guide the limiting guide pin to perform a steerable movement. Because the rotating shaft Ⅱ24 is hingedly connected to the middle position of the shift fork 10, when the rotating shaft Ⅱ24 performs circular motion, it can drive the shift fork 10 to perform a crank-connecting rod motion. The U-shaped groove 21 at the front end of the upper layer of the shift fork 10 can just clamp the cylindrical pin 20 of the extension arm of the hexagonal turntable Ⅱ8 inside and the lower end surfaces of the two are flush, so that the lower layer of the shift fork 10 will not interfere with the cylindrical pin 20 when performing a crank motion. When the fork 10 performs a crank-connecting rod motion, the U-shaped groove 21 at the front end of the fork 10 moves in an elliptical route. When the U-shaped groove 21 moves forward in an arc, the cylindrical pin 20 can be inserted into the U-shaped groove 21. In the process of driving the cylindrical pin 20 to move through the U-shaped groove 21, the blocked cylindrical pin 20 drives the hexagonal turntable II8 to perform a circular motion at a certain angle, and disengages from the above-mentioned cylindrical pin 20 after the U-shaped groove 21 moves a certain elliptical arc length. After the cylindrical pin 20 disengages from the fork 10, there is no external force to drive the hexagonal turntable II8, so that the hexagonal turntable II8 is in a stationary state. When the fork 10 performs the next cycle of crank-connecting rod motion, the U-shaped groove 21 repeats the above-mentioned motion to block the next adjacent cylindrical pin 20 and then drive the movement and finally disengage, thereby making the hexagonal turntable II8 rotate intermittently. The hexagonal turntable II8 is coaxially fixed with the hexagonal turntable I12, and can drive the hexagonal turntable I12 to rotate synchronously and intermittently.

[0070] Preferably, a guide rod 65 is provided on the turntable Ⅰ12, a sliding sleeve 66 is clamped on the guide rod 65, a clamping hinge frame 67 is fixed on the sliding sleeve 66, the clamping hinge frame 67 is U-shaped, and triangular rotating heads 68 are hinged at the two side ends of the clamping hinge frame 67, and soft belts 69 are connected to the inner sides of the two rotating heads 68. The soft belts 69 are made of rubber and have elastic deformation characteristics; a test tube holder 70 is inserted downward into the guide rod 65 of the turntable Ⅰ12, and a guide rod hole 71 is provided on the test tube holder 70. The guide rod 65 is sleeved in the guide rod hole 71, and an entry groove 72 is provided on the test tube holder 70 along the radial direction from the middle to the edge position. The bottom of the collection test tube 13 is provided on the entry groove 72, and the upper part of the collection test tube 13 is clamped and fixed by the clamping hinge frame 67. A top pin 73 and a spring 74 are successively installed on the test tube holder 70 at the lower part of the entry groove 72.

[0071] A guide rod 65 is provided on the upper end surface of the extension arm of the hexagonal turntable Ⅰ12. The guide rod 65 is a hexagonal prism with guiding characteristics. A sliding sleeve 66 is clamped on the guide rod 65. The sliding sleeve 66 is fixed with a clamping hinge frame 67 on the outer wall of the outer side of the hexagonal turntable Ⅰ12. The clamping hinge frame 67 is U-shaped as a whole. Triangular rotating heads 68 are hinged at the two side ends of the clamping hinge frame 67. A soft belt 69 is connected to the inner side of the rotating head 68. The soft belt 69 is made of rubber and has elastic deformation characteristics. The rotating head 68 and the soft belt 69 have two states, one is that the rotating heads 68 on both sides are rotated to the outside so that the soft belt 69 is released and bounced open, and the other is that the rotating heads 68 on both sides are rotated to the inside so that the soft belt 69 is concave inward and released. The soft belt 69 in both states can maintain a stable state in conjunction with the rotating head 68. In both states, the rotating heads 68 and the soft belts 69 on both sides can clamp the tube wall of the collection tube 13 toward the center, so that the collection tube 13 is in a fixed clamping state.

[0072] A test tube holder 70 is inserted downwardly into the guide rod 65 of the hexagonal turntable Ⅰ12. A guide rod hole 71 is provided on the test tube holder 70 so that it can move vertically up and down along the guide rod 65. A collection test tube 13 is supported on the upper side of the test tube holder 70 to prevent the collection test tube 13 from sliding downward when it is pressed down by the pressing seat 78 and clamped by the rotating head 68 and the soft belt 69. The test tube holder 70 is a circular ring with a certain thickness. The upper end surface of the test tube holder 70 is radially to the edge at a position where the bottom of the collection test tube 13 is directly opposite to the upper end surface of the test tube holder 70. The edge of the collecting tube 13 is provided with an advance groove 72, which is an arc groove and has a contour design with the bottom of the collecting tube 13. The advance groove 72 facilitates the collecting tube 13 to advance radially inward when clamped. A push pin 73 is provided on the end face of the advance groove 72 directly opposite to the bottom of the collecting tube 13. A spring 74 is provided between the lower end and the bottom of the push pin 73. The spring 74 supports the push pin 73. The push pin 73 can support the collecting tube 13, thereby further preventing the collecting tube 13 from loosening up and down.

[0073] Preferably, the clamping power component includes: a column 75, a connecting rod I 76, a connecting rod II 77, a pressure seat 78, and a motor II 79; a column 75 is arranged on the platform 7, and connecting rods I 76 and II 77 are hinged on the column 75 respectively, and the other ends of connecting rods I 76 and II 77 are hinged with a pressure seat 78, and the column 75 is connected to a motor II 79, which is hinged to the connecting rod I 76, and the pressure seat 78 is raised and pressed down to control the conical plug 14 to plug the collection tube 13.

[0074] A column 75 is vertically fixed on the platform 7 outside the heat-insulating shielding shell 25. The upper end of the column 75 is hinged with a connecting rod Ⅰ76 and a connecting rod Ⅱ77 in the front and rear directions respectively. The other ends of the connecting rods Ⅰ76 and Ⅱ77 are hinged with a pressing seat 78. A motor Ⅱ79 is fixed on the column 75. The motor Ⅱ79 is connected to the hinge shaft of the connecting rod Ⅰ76. When the motor Ⅱ79 is turned on, the pressing seat 78 can be raised and pressed down through the connecting rod mechanism of the connecting rod Ⅰ76 and the connecting rod Ⅱ77. The lower part of the pressing seat 78 faces the tube mouth of one of the clamped collection test tubes 13. The tube mouth is matched with a conical plug 14. The conical plug 14 can plug and fix the tube mouth of the collection test tube 13 to ensure air tightness. The edge of the conical plug 14 is connected to the egg extraction tube 15 and the negative pressure extraction tube 16. When the pressing seat 78 is pressed down, the middle area of ​​the conical plug 14 can be pressed tightly, further ensuring that the conical plug 14 does not slip off the tube mouth of the collection test tube 13. A negative pressure box 17 and a flushing box 19 are fixed to the side of the upper end surface of the platform 7. The negative pressure extraction tube 16 of the conical plug 14 is connected to the negative pressure box 17, the egg extraction tube 15 is connected to the main joint of the needle seat 51 at the rear end of the egg retrieval needle 3, and the flushing tube 18 on the secondary joint of the needle seat 51 is connected to the negative pressure box 17.

[0075] When it is necessary to perform an egg extraction operation on the livestock ovary 81, the entire operation is performed in a dark environment because the eggs are afraid of light. In the initial state, the movable handle 28 is toggled to rotate the arc-shaped baffle 26 from the shielding state to the retracted state, and at the same time, each structure is installed back to its original position. The probe flap 2 at the front end of the vaginal ultrasound probe frame 1 is in a closed state, the conical plug 14 is tightly plugged in the tube mouth of the collection test tube 13, and the pressure seat 78 is pressed down on the upper end of the conical plug 14 to fix the conical plug 14 at the tube mouth of the collection test tube 13. The transvaginal ultrasound probe holder 1 is inserted into the vagina of the livestock. When the transvaginal ultrasound probe holder 1 enters a certain depth into the vagina of the livestock, the knob 43 is turned. The knob 43 drives the worm 41 to rotate through the worm rotating rod 42. The worm 41 drives the worm wheels 44 on both sides to rotate. The worm wheels 44 drive the two probe flaps 2 to open synchronously on both sides. While opening, the probe flaps 2 push the inner wall of the deep vagina to both sides until it bulges. The opened probe flaps 2 confirm the position of the ovary 81 through ultrasonic positioning, and then slightly adjust the transvaginal ultrasound probe holder 1. After the insertion depth inside the vagina is adjusted, the egg retrieval needle 3 is passed through the vaginal ultrasound probe frame 1 and obliquely penetrates the probe petal 2 under its guidance to pierce the ovary 81. The front end of the egg retrieval needle 3 reaches the position of the ovarian 81 follicle 82. The flushing box 19 passes the flushing liquid into the flushing tube 18 to flush the follicle 82 to ensure the activity of the follicle 82. The negative pressure box 17 turns on the negative pressure mode to pump the gas inside the collection tube 13 into the negative pressure box 17 through the negative pressure tube, so that the inside of the collection tube 13 is in a negative pressure state. The collection tube 13 in a negative pressure state can extract eggs from the follicle 82 under negative pressure through the egg extraction tube 15 and the egg retrieval needle 3. At this time, the power box 36 is turned on to heat the insulation tube 37 to heat and keep the middle collection tube 13 warm.

[0076] When the eggs in the collection tube 13 are extracted and collected, the motor II 79 is turned on in the reverse direction. The motor II 79 controls the connecting rod I 76 and the connecting rod II 77 to drive the pressing seat 78 to lift up and take out the conical plug 14. Turn on the motor I52, and the motor I52 drives the synchronous pulley II54 and the synchronous pulley I53 to rotate synchronously. The synchronous pulley I53 drives the rotating rod 9 to rotate synchronously through the rotating shaft I23, and the rotating rod 9 drives the rotating shaft II24 at the other end to perform circular motion. Because the rotating plate I60 and the rotating plate II62 can rotate synchronously, they play a steerable guiding movement through the limiting guide pin, and because the rotating shaft II24 is hingedly connected to the middle position of the fork 10, when the rotating shaft II24 performs a circular motion, it can drive the fork 10 to perform a crank-connecting rod motion, so that the U-shaped groove 21 at the front end of the fork 10 can position the cylindrical pin 20 to control the hexagonal turntable II8 and the hexagonal turntable I12 to perform intermittent circular motion synchronously, so that the next group of collection test tubes 13 are moved to the specified position and the conical plug 14 is inserted. Turn on the motor II79 to control the pressure seat 78 to press down and fix the conical plug 14, and then negative pressure sucks the eggs into the collection test tube 13. This operation is repeated until the egg retrieval is completed, and then the movable handle 28 is moved to rotate the arc-shaped blocking piece 26 to a shielding state.

[0077] The innovative technical points and beneficial effects of the present invention are at least:

[0078] 1. The transvaginal ultrasound probe holder 1 is tubular and has an internal obliquely arranged puncture guide channel 4 that guides the egg retrieval needle 3. After the position of the ovary 81 is ascertained and adjusted, the puncture needle can be directly punctured to the position of the ovary 81 through the internal puncture guide channel 4. The egg retrieval needle 3 does not need to be manually adjusted in direction, and the operation is simple and convenient, which greatly improves the efficiency of egg retrieval. It avoids the traditional method of manually controlling the direction of the egg retrieval needle 3 from the outside of the transvaginal ultrasound probe holder 1 for puncture, which may cause hand shaking, deviation in the puncture position, and lead to the wrong puncture position. The traditional method takes a long time and requires high skills from the operator, which can easily cause soreness in the operator's hands, and the wrong puncture position will cause unnecessary damage to the health of livestock.

[0079] 2. The front end of the vaginal ultrasound probe holder 1 adopts a worm gear to control the opening and closing of the flap-type ultrasound probe. Because the ovaries 81 are located on both sides of the vagina and the uterus, the worm gear controls the opening of the ultrasound probe to ensure that the vaginal ultrasound probe holder 1 will not tilt. When it is always in the right direction, the probe flap 2 can be simply lifted up against the vaginal wall to detect the position of the ovaries 81. At the same time, the synchronous opening and lifting of both sides can ensure the force balance of the vaginal ultrasound probe holder 1, which is always in the right direction, ensuring the stability of the exploration. At the same time, the vaginal ultrasound probe holder 1 can also be easily kept in the right direction when exploring for puncture. At the same time, the worm gear mechanism has a self-locking effect to ensure the stable opening of the probe flap 2. However, the front end of the conventional vaginal ultrasound probe frame 1 is not provided with an openable and closable probe flap 2. The operator simply controls the front end ball head of the vaginal ultrasound probe frame 1 by hand to obliquely lift the vaginal wall to explore the position of the ovary 81. When in the inclined state, the more the rear end of the vaginal ultrasound probe frame 1 tilts, the more likely it is that the livestock's vagina will be torn. At the same time, the overall tilting of the vaginal ultrasound probe frame 1 in the livestock's vagina by hand-held control cannot effectively ensure that the vaginal ultrasound probe frame 1 is always in a stable tilt angle state when the egg retrieval needle 3 is punctured after the ovary 81 is located.

[0080] 3. The heat-insulating shielding shell 25 can control the arc-shaped baffles 26 to cover and shield the collection tube 13 synchronously and uniformly, further ensuring the light-shielding property of the collection tube 13 in a dark environment, and when it is needed to be opened, all the arc-shaped baffles 26 on the circumference can be controlled to rotate and open synchronously by turning the movable handle 28, which is convenient and quick. The threaded coiled heat-insulating tube 37 can effectively heat the collection tube 13 inside to simulate the environment of the egg inside the uterus, and can effectively prevent the egg inside the collection tube 13 from having reduced activity during the collection process.

[0081] 4. The rotating rod 9 drives the fork 10 to realize the intermittent circular rotation of the hexagonal turntable II 8, so that each group of collection test tubes 13 can have enough pause time to collect eggs, and after the eggs are collected in the corresponding collection test tubes 13, they can automatically rotate to the next group of collection test tubes 13 to pause and wait for collection, which can effectively control the operator's unnecessary operations other than egg retrieval, greatly speeding up the egg retrieval time.

[0082] 5. The connecting rod structure controlled by the motor II 79 drives the pressure seat 78 to press down and lift the conical plug 14, which can ensure the airtightness inside the collection tube 13 and prevent the conical plug 14 from leaking. At the same time, the egg extraction tube 15 and the negative pressure extraction tube 16 connected to the conical plug 14 can control the negative pressure space inside the collection tube 13 to extract through the egg retrieval needle 3.

[0083] 6. The clamping structure rotating head 68 cooperates with the soft belt 69 to clamp the collection tube 13, and the structure facilitates the sideways extraction of the collection tube 13 when it is needed to be detached. Cooperating with the entry groove 72 of the test tube holder 70 and the internal ejector pin 73 and spring 74, the collection tube 13 can be further prevented from loosening up and down. The stability of the collection tube 13 in the clamped state is ensured, and there will be no loosening up and down.

[0084] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
