Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, in particular to an embryo transplantation device. Background Art

[0002] Embryo transfer refers to the technology of transplanting early embryos in female animals, or embryos obtained through in vitro fertilization and other methods, into other female animals of the same species and with the same physiological conditions, so that they continue to develop into new individuals.

[0003] For example, the announcement number CN215458505U proposes a transplantation device for in vitro fertilization embryo transplantation, which belongs to the field of medical device technology. A transplantation device for in vitro fertilization embryo transplantation includes a booster and a transplantation tube. The booster includes an open-close syringe placement cavity and a motor-type booster cavity. Two semi-cylindrical fixed blocks are arranged in the open-close syringe placement cavity, and a fixed groove is opened on the fixed block. A syringe is arranged in the fixed groove. A fixed assembly is arranged on the fixed block. A drive assembly is arranged in the motor-type booster cavity. A transplantation tube is arranged on the syringe needle, and an injection stabilization mechanism is connected to the outside of the transplantation tube. In the device, the syringe is fixedly clamped inside the open-close syringe placement cavity, and the piston rod of the syringe is controlled by the protruding push rod of the motor-type booster cavity. The syringe is controlled to complete the injection with a steady force and speed. The injection stabilization mechanism arranged on the outside of the transplantation tube controls the rubber ring. After the transplantation tube is positioned at the uterine fundus, the rubber ring is used to clamp the cervix to stabilize the transplantation tube.

[0004] At present, the existing transplantation device is relatively simple in setting, and is only used to achieve the transplantation work. During the transplantation process, some air will remain inside the injection tube, which will lead to possible air pollution problems during the transplantation process. If the embryo is contaminated during the transplantation process, the probability of success of the test tube baby will be reduced; in addition, during the embryo transplantation process, due to differences in the human body, some people have a longer cervix, and the injection tube needs to be replaced at this time. The cervix lengths of different people are different, so the selection process is more cumbersome, which affects the embryo transplantation operation; moreover, during the transplantation, it will cause certain stimulation to the uterine muscle tissue of the transplanted mother, and even accidentally injure the muscle tissue, which is not conducive to the overall transplantation work.

[0005] In view of the above problems, an embryo transplantation device is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an embryo transplantation device. By using this device to work, the problem that the embryo is contaminated during the transplantation process in the above background will be reduced in the probability of success of in vitro fertilization. In addition, due to differences in human bodies, some people have longer cervixes, and the injection tube needs to be replaced at this time, which is more cumbersome in the selection process. Moreover, during the transplantation, the uterine muscle tissue may be accidentally injured, which is not conducive to the overall transplantation work.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an embryo transplantation device, comprising a transplantation tube, a cavity is opened inside the transplantation tube, a push rod is slidably connected to the top of the cavity, an injection tube is fixedly connected to the bottom wall of the cavity, one end of the push rod is fixedly connected to a piston, the piston is sealingly and slidably connected to the inside of the cavity, an exhaust assembly is installed inside the push rod, an adjustment assembly is installed inside the injection tube, and an auxiliary assembly is installed inside the transplantation tube.

[0008] Furthermore, the exhaust component includes a first slide groove, which is opened on the inner wall of the push rod, and a spring is fixedly connected to the top wall of the first slide groove. One end of the spring is fixedly connected to a sleeve, and the sleeve is embedded in the inner wall of the first slide groove and is slidably connected.

[0009] Furthermore, a rubber plug is fixedly connected to the bottom wall of the sleeve, and the rubber plug is sealingly and slidingly connected to the piston. A clamping block is symmetrically and fixedly connected to the inner wall of the sleeve. A rotating rod is rotatably connected to the top wall of the first slide groove, and a knob is fixedly connected to the side wall at one end of the rotating rod.

[0010] Furthermore, the other end of the rotating rod is fixedly connected to a fixing rod, the spring is sleeved on the outer ring of the rotating rod, and the side walls of the fixing rod are symmetrically fixedly connected to arc plates, and each of the arc plates slides against an adjacent block.

[0011] Furthermore, the adjustment component includes two first mounting grooves, the two first mounting grooves are symmetrically opened on the inner top wall of the injection tube, the inner bottom wall of the injection tube is provided with a second slide groove, and each of the first mounting grooves is connected to the second slide groove.

[0012] Furthermore, a flow guide pipe is fixedly connected to the inner wall of each of the first installation grooves, a first control valve is installed inside each of the flow guide pipes, and one end of each of the flow guide pipes extends to the inside of the second slide groove.

[0013] Furthermore, a rubber ring is sealingly and slidably connected to the inner wall of the second slide groove, a first connecting plate is fixedly connected to the bottom end of the rubber ring, a moving tube is fixedly connected to one end of the first connecting plate, and both the first connecting plate and the moving tube are slidably connected to the inside of the second slide groove.

[0014] Furthermore, the auxiliary component includes a second connecting plate, which is fixedly connected to the side wall of the push rod. An air cavity is opened on the inner wall of one side of the transplant tube, a round hole is opened on the top of the air cavity, and a connecting rod is fixedly connected to the bottom wall of the second connecting plate.

[0015] Furthermore, one end of the connecting rod passes through the circular hole and extends into the air cavity. A sealing plate is fixedly connected to the side wall of one end of the connecting rod located inside the air cavity. The sealing plate is sealingly and slidingly connected to the inner wall of the air cavity. A connecting pipe is fixedly connected to the bottom wall of the air cavity.

[0016] Furthermore, a second control valve is installed inside the connecting pipe, one end of the connecting pipe is fixedly connected to a protective ring, the protective ring is fixedly connected to the bottom end of the moving pipe, a pressure relief hole is opened on the side wall of the air cavity, and a third control valve is installed inside the pressure relief hole.

[0017] Compared with the prior art, the present invention has the following beneficial effects: By setting an exhaust component and turning the knob, the rotation of the knob drives the rotating rod and the fixed rod to rotate. As the fixed rod rotates, the arc plate on its side wall will come into contact with the block on the inner wall of the sleeve, thereby driving the block to be pushed upward until the block moves to the top wall of the arc plate. As the fixed rod continues to rotate, the block will leave the arc plate and push the sleeve downward under the elastic action of the spring. During the downward movement of the sleeve, the rubber plug will be driven to move synchronously, thereby completely exhausting the residual air in the injection tube. By completely exhausting the air inside the transplantation device, the embryo is transplanted, thereby avoiding the influence of air pollution on embryo transplantation and improving the transplantation efficiency. The success rate is improved; by setting the adjustment component, when the push rod drives the piston to move and the first control valve is opened during the exhaust process of the transplant tube, the pressure inside the cavity will increase during the exhaust process. At this time, after the first control valve is opened, part of the internal air pressure will enter the second chute along the guide tube. As the gas moves, the internal pressure of the second chute increases, which will push the rubber ring to move, thereby pushing the first connecting plate and the moving tube to extend outward to achieve the length of the cervix required for transplantation; by changing the length of the injection tube and the moving tube during the exhaust process of the transplant tube, it can be suitable for different cervical lengths, the operation is simple and convenient, and the practicality of the device is improved; By setting up an auxiliary component, the connecting pipe is connected to the protective ring, and the second control valve is opened. Then, during the movement of the push rod to exhaust, the sealing plate is driven to move synchronously through the second connecting plate and the connecting rod. The pressure difference generated by the sealing plate and the sealing sliding inside the air cavity is utilized to allow the gas inside the air cavity to enter the protective ring along the connecting pipe, causing the protective ring to expand until the injection port of the moving tube is completely wrapped. Therefore, even if accidental injury occurs during the movement, the expanded protective ring can be used for protection to avoid direct contact with the uterine muscle tissue to cause accidental injury, thereby improving the use effect of the device.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to solve the technical problem that the existing transplantation device is relatively simple and only performs the transplantation work simply, some air will be stored in the injection tube 4 during the transplantation process, which will lead to possible air pollution problems during the transplantation process. If the embryo is contaminated during the transplantation process, the probability of successful test tube baby will be reduced. Figure 1 - Figure 5 As shown, the following preferred technical solutions are provided: An embryo transplantation device includes a transplantation tube 1, a cavity 11 is provided inside the transplantation tube 1, a push rod 2 is slidably connected to the top of the cavity 11, an injection tube 4 is fixedly connected to the bottom wall of the cavity 11, and a piston 21 is fixedly connected to one end of the push rod 2. The principle of the currently commonly used embryo transplantation device is to connect the syringe to the transplantation tube 1, and a certain amount of transplantation fluid containing the embryo is sucked into the transplantation tube 1 through the movement of the piston 21 in the syringe, and then the embryo and the transplantation fluid are moved into the mother's uterus together to complete the embryo transplantation. The piston 21 is sealed and slidably connected to the inside of the cavity 11, and an exhaust component 3 is installed inside the push rod 2. By setting the exhaust component 3, the knob 36 is turned, and the knob 36 rotates to drive the rotating rod 3 5 and the fixing rod 37 rotate. As the fixing rod 37 rotates, the arc plate 38 of its side wall will contact with the block 34 on the inner wall of the sleeve 33, thereby driving the block 34 to push upward until the block 34 moves to the top wall of the arc plate 38. As the fixing rod 37 continues to rotate, the block 34 will leave the arc plate 38 and push the sleeve 33 downward under the elastic action of the spring 32. During the downward movement of the sleeve 33, the rubber plug 39 will be driven to move synchronously, thereby completely exhausting the residual air in the injection tube 4. By completely exhausting the air in the transplantation device, the embryo is transplanted, thereby avoiding the influence of air pollution on embryo transplantation and improving the success rate of transplantation.

[0022] An adjusting assembly 5 is installed inside the injection tube 4. By setting the adjusting assembly 5, when the push rod 2 drives the piston 21 to move and the inside of the transplant tube 1 is exhausted, the first control valve 54 is opened. During the exhaust process, the internal pressure of the cavity 11 will increase. At this time, after the first control valve 54 is opened, a part of the internal air pressure will enter the second slide groove 52 along the guide tube 53. As the gas moves, the internal pressure of the second slide groove 52 increases, and the rubber ring 55 will be pushed to move, thereby pushing the first connecting plate 56 and the moving tube 57 to extend outward to achieve the length of the cervix required for transplantation; by changing the length of the injection tube 4 and the moving tube 57 during the exhaust process of the transplant tube 1, it can be suitable for different cervical lengths, the operation is simple and convenient, and the practicality of the device is improved.

[0023] An auxiliary component 6 is installed inside the transplant tube 1. By setting up the auxiliary component 6, the connecting tube 65 is connected to the protective ring 66, and the second control valve 68 is opened. Then, when the push rod 2 moves to exhaust, the sealing plate 64 is driven to move synchronously through the second connecting plate 61 and the connecting rod 62. The pressure difference generated by the sealing plate 64 and the sealing sliding inside the air cavity 12 is used to make the gas inside the air cavity 12 enter the protective ring 66 along the connecting tube 65, so that the protective ring 66 begins to expand until the injection port of the moving tube 57 is completely wrapped. Therefore, during the movement, even if accidental injury occurs, it can be protected by the expanded protective ring 66 to avoid direct contact with the uterine muscle tissue to cause accidental injury, thereby improving the use effect of the device.

[0024] The exhaust assembly 3 includes a first slide groove 31, which is opened on the inner wall of the push rod 2. A spring 32 is fixedly connected to the inner top wall of the first slide groove 31. One end of the spring 32 is fixedly connected to a sleeve 33. The sleeve 33 is embedded and slidably connected with the inner wall of the first slide groove 31. In the initial state, the block 34 is located near the top of the arc plate 38. At this time, the spring 32 is in a compressed state, and the rubber plug 39 is located inside the piston 21. In addition, during the rotation process, the rotating rod 35 can only rotate in one direction through the external thorn gear, thereby limiting the arc plate 38 and the block 34.

[0025] A rubber plug 39 is fixedly connected to the bottom wall of the sleeve 33, and the rubber plug 39 is sealed and slidably connected to the piston 21. A clamping block 34 is symmetrically fixedly connected to the inner wall of the sleeve 33. A rotating rod 35 is rotatably connected to the inner top wall of the first sliding groove 31, and a knob 36 is fixedly connected to the side wall of one end of the rotating rod 35.

[0026] The other end of the rotating rod 35 is fixedly connected to a fixing rod 37, and a spring 32 is sleeved on the outer ring of the rotating rod 35. The side wall of the fixing rod 37 is symmetrically fixedly connected to an arc plate 38. Each arc plate 38 slides against the adjacent block 34. There is a sufficient distance between the two arc plates 38. Therefore, when the block 34 slides to the top of the arc plate 38, under the elastic action of the spring 32, the block 34 will not contact the arc plate 38 when moving downward, causing a limiting effect.

[0027] In this scheme: before embryo transplantation, first push the push rod 2 to drive the piston 21 to move, and use the pressure difference generated by the sealed sliding between the piston 21 and the inner wall of the cavity 11 to completely discharge the air inside the transplant tube 1 along the injection tube 4. However, at this time, there is still some air inside the injection tube 4 that has not been completely discharged, which will cause air pollution and affect the success rate of in vitro fertilization. Therefore, it is necessary to discharge the air inside the injection tube 4 together. At this time, turn the knob 36, and the rotation of the knob 36 drives the rotating rod 35 and the fixed rod 37 to rotate. As the fixed rod 37 rotates, the arc plate 38 of its side wall will contact the block 34 on the inner wall of the sleeve 33, thereby driving the block 34 to push upward. , until the block 34 moves to the top wall of the arc plate 38. As the fixing rod 37 continues to rotate, the block 34 will leave the arc plate 38 and push the sleeve 33 downward under the elastic action of the spring 32. During the downward movement of the sleeve 33, the rubber plug 39 will be driven to move synchronously. The rubber plug 39 is made of a flexible material. Therefore, when the sleeve 33 moves downward, the rubber plug 39 will be driven to move along the injection tube 4 until the rubber plug 39 is moved to the end of the injection tube 4, thereby completely discharging the residual air in the injection tube 4. Since the rubber plug 39 is made of a flexible material, the rubber plug 39 will change with the internal shape of the injection tube 4 during the movement. When the rubber stopper 39 needs to be reset and the culture medium and embryos need to be pumped in, the rotating rod 35 is continuously rotated to make the arc plate 38 contact the block 34. The oblique arc plate 38 is used to drive the block 34 and the sleeve 33 to move upward during the rotation process until the rubber stopper 39 moves into the piston 21. At this time, the push rod 2 is pushed to drive the piston 21 to move upward, thereby pumping the culture medium and embryos into the cavity 11 along the injection tube 4. In the initial state, the block 34 is located near the top of the arc plate 38, at which time the spring 32 is in a compressed state, and the rubber plug 39 is located inside the piston 21, and the rotating rod 35 can only rotate in one direction during rotation through the external thorn gear, thereby limiting the arc plate 38 and the block 34; in addition, there is a sufficient distance between the two arc plates 38, so that when the block 34 slides to the top of the arc plate 38, under the elastic action of the spring 32, the block 34 will not contact the arc plate 38 when moving downward, causing a limiting effect.

[0028] In order to solve the problem that during embryo transfer, due to differences in human bodies, some people have longer cervixes, and the injection tube 4 needs to be replaced, and the length of the cervix of different people is different, so the selection process is more complicated and affects the technical problems of embryo transfer operation, such as Figure 2 and Figure 6 - Fig. 9 As shown, the following preferred technical solutions are provided: The adjustment component 5 includes two first mounting grooves 51 symmetrically arranged on the inner top wall of the injection tube 4 . A second slide groove 52 is arranged on the inner bottom wall of the injection tube 4 . Each first mounting groove 51 is connected to the second slide groove 52 .

[0029] A flow guide tube 53 is fixedly connected to the inner wall of each first installation groove 51 . A first control valve 54 is installed inside each flow guide tube 53 . One end of each flow guide tube 53 extends to the inside of the second slide groove 52 .

[0030] The inner wall of the second slide groove 52 is sealingly and slidably connected with a rubber ring 55, the bottom end of the rubber ring 55 is fixedly connected with a first connecting plate 56, one end of the first connecting plate 56 is fixedly connected with a moving tube 57, and the first connecting plate 56 and the moving tube 57 are both slidably connected to the inside of the second slide groove 52.

[0031] In this solution, due to differences in human bodies, different cervical lengths lead to the need to select different lengths of injection tubes 4 before transplantation, which is rather cumbersome. After determining the cervical length, the push rod 2 drives the piston 21 to move, and during the exhaust process of the transplant tube 1, the first control valve 54 is opened. During the exhaust process, the pressure inside the cavity 11 will increase. At this time, after the first control valve 54 is opened, part of the internal air pressure will flow along the guide tube 53 into the second chute 52. As the gas flows, the internal pressure of the second chute 52 increases, which will push the rubber ring 55 to move, thereby pushing the first connecting plate 56. The movable tube 57 is extended outward, thereby changing the length of the injection tube 4 and the movable tube 57 to achieve the length of the cervix required for transplantation, and then the first control valve 54 is closed to form a closed space between the guide tube 53 and the rubber ring 55, so that the movable tube 57 is firmly adsorbed inside the second slide groove 52, thereby improving stability and avoiding the separation of the movable tube 57 and the injection tube 4 during the transplantation process. By changing the length of the injection tube 4 and the movable tube 57 during the exhaust process inside the transplantation tube 1, it can be adapted to different cervical lengths, the operation is simple and convenient, and the practicality of the device is improved.

[0032] In order to solve the technical problem that during the transplantation, the uterine muscle tissue of the transplanted mother will be stimulated to a certain extent, or even accidentally injured, which is not conducive to the overall transplantation work, such as Fig.10 - Fig.11 As shown, the following preferred technical solutions are provided: The auxiliary component 6 includes a second connecting plate 61, which is fixedly connected to the side wall of the push rod 2. An air cavity 12 is formed on the inner wall of one side of the transplant tube 1, a round hole 63 is formed on the top of the air cavity 12, and a connecting rod 62 is fixedly connected to the bottom wall of the second connecting plate 61.

[0033] One end of the connecting rod 62 passes through the circular hole 63 and extends into the air cavity 12 . A sealing plate 64 is fixedly connected to the side wall of one end of the connecting rod 62 located inside the air cavity 12 . The sealing plate 64 is sealingly and slidably connected to the inner wall of the air cavity 12 . A connecting pipe 65 is fixedly connected to the bottom wall of the air cavity 12 .

[0034] A second control valve 68 is installed inside the connecting pipe 65. One end of the connecting pipe 65 is fixedly connected to a protective ring 66. The protective ring 66 is fixedly connected to the bottom end of the moving pipe 57. A pressure relief hole 67 is opened on the side wall of the air cavity 12. A third control valve 69 is installed inside the pressure relief hole 67.

[0035] In this scheme: the existing syringe ends lack protection. The inner wall of some maternal uteri is relatively thin. If a puncture occurs at the syringe port during the transplantation process, the embryo transplantation operation will be affected. Before exhausting the inside of the transplantation tube 1, the connecting tube 65 is connected to the protective ring 66, and the second control valve 68 is opened. Then, during the movement of the push rod 2 for exhaust, the sealing plate 64 is driven to move synchronously by the second connecting plate 61 and the connecting rod 62. The pressure difference generated by the sealing plate 64 and the sealing sliding inside the air cavity 12 is used to make the gas inside the air cavity 12 enter the protective ring 66 along the connecting tube 65, so that the protective ring 66 begins to expand until the injection port of the moving tube 57 is completely wrapped. Therefore, even if an accidental injury occurs during the movement, the expanded protective ring 66 can be used for protection to avoid direct contact with the uterine muscle tissue to cause accidental injury, thereby improving the use effect of the device. When the protective ring 66 is fully expanded, but the push rod 2 has not moved to the bottom of the transplant tube 1, the third control valve 69 is opened. As the push rod 2 continues to move downward, excess gas will be discharged along the pressure relief hole 67, and finally the connecting tube 65 will be separated from the protective ring 66. The protective ring 66 is similar to a football structure. After inflation is completed, the gas can be stored and will not be discharged immediately, so that the protective ring 66 can flexibly protect the port of the moving tube 57 after expansion.
