Description

{OVUM PICK-UP DEVICE WITH ADJUSTABLE FLUSHING}

The present invention relates to an egg retrieval device capable of controlling flushing, and more specifically, to an egg retrieval device capable of controlling flushing, which enables a user to wash and suction an egg or follicular fluid without the assistance of an assistant during a procedure for retrieving an egg or follicular fluid inside an ovary, thereby easily controlling the number of flushing processes for retrieving an egg and the amount of culture medium injected, thereby allowing the egg retrieval procedure to be performed conveniently and stably.

In vitro fertilization is a method in which eggs are collected outside the body before ovulation from the ovaries, fertilized in a test tube, and the fertilized embryos are then transferred back into the uterus through the cervix.

In vitro fertilization (IVF) involves a process in which an obstetrician/gynecologist extracts eggs or follicular fluid from a woman's ovaries while looking at an ultrasound image.

At this time, the process of collecting an egg or follicular fluid is called flushing, and this flushing refers to the process of an obstetrician/gynecologist (hereinafter referred to as the "user") inserting a double lumen needle into the female reproductive organ, i.e., the vagina, and injecting/spraying a culture solution through it to wash the follicular fluid and repeating the process of aspirating an egg or follicular fluid to ensure the aspiration of an intact egg.

In the past, the procedure was performed by having an assistant assist the user operate a syringe filled with culture medium to spray the culture medium to wash the follicular fluid, and then having the user aspirate the egg or follicular fluid.

However, in these cases, the user had to inform and check the assistant each time the amount of culture solution to be injected based on the size of the follicle confirmed through ultrasound, which made the procedure not smooth, and if the assistant was inexperienced, there were cases where the follicle ruptured because the flushing speed was not controlled.

In addition, if the breathing of the user and the assistant is not in sync, there is a delay in the flushing process itself, which not only increases the time required for the egg retrieval procedure, but also places a burden on the patient who wants to retrieve the egg.

Therefore, a method to solve these problems is required.

Hereinafter, preferred embodiments of the present invention, in which the purpose of the present invention can be specifically realized, will be described with reference to the attached drawings. In describing the present embodiments, the same names and symbols are used for the same components, and additional descriptions thereof will be omitted.

The present invention relates to an oocyte retrieval device capable of controlling flushing, which enables a user to wash and suction an oocyte or follicular fluid without the assistance of an assistant during a procedure for retrieving an oocyte or follicular fluid inside an ovary, thereby easily controlling the number of flushing processes for retrieving an oocyte and the amount of culture medium injected, thereby allowing the oocyte retrieval procedure to be performed conveniently and stably.

The above-described egg retrieval device, as illustrated in FIG. 1, comprises a main body (100) in which a guide channel (500) that serves as a passage for the culture solution sprayed to wash the follicular fluid inside and the oocyte or follicular fluid sucked for the retrieval of the oocyte can be formed, a power unit (M) that can be provided in the main body (100) to generate power so that the culture solution, oocyte or follicular fluid can move along the guide channel, and which has a motor whose suction and discharge can be selectively controlled so that either the spraying of the culture solution or the suction of the oocyte or follicular fluid can be selectively performed, a drive lever (130) that can be provided in the main body (100) to control the driving of the power unit (M) and turn it on/off, and to enable the output of the power unit (M) to be finely adjusted, and a drive lever (130) that can be detachably connected to the main body (100) and at least a part of which is inserted into a woman's vagina so that the culture solution is sprayed or the oocyte or follicular fluid is sucked by the driving of the power unit (M). It may be composed of an intubation unit (200) that enables suction of ovules, a syringe unit (300) that can be detachably coupled to the main body (100) and has a culture medium filled therein so that the culture medium can be supplied to the intubation unit (200) by the discharge drive of the power unit (M), and a storage unit (400) that can be detachably coupled to the main body (100) and allows ovules or ovarian fluid sucked from the intubation unit (200) by the suction drive of the power unit (M) to be transported and stored.

At this time, the intubation unit (200), syringe unit (300) and storage unit (400) are connected to the main body (100) so as to be mutually connected with the guide path (500) formed inside the main body (100), thereby enabling smooth spraying of the culture solution or suction of the oocyte or follicular fluid.

In addition, although the drawing of the present invention depicts the power unit (M) as being provided inside the main body (100), it is not limited thereto, and it should be recognized that it may be provided so as to be detachable on the outside, such as the top or side of the main body (100), so that maintenance such as replacement or inspection of the power unit (M) can be easily performed.

According to one embodiment of the present invention, the guide channel (500) formed inside the main body (100) has one side communicating with the intubation unit (200) coupled to the main body (100), the other side communicating with the syringe unit (300) coupled to the main body (100), and the first channel (510) that allows the culture medium filled in the syringe unit (300) to move from the syringe unit (300) to the intubation unit (200) by the discharge drive of the power unit (M), and the storage unit (400) that has one side communicating with the first channel (510) and the other side communicating with the main body (100), and the oocyte or It can be formed by including a second path (520) that allows the ovarian fluid to move toward the storage unit (400).

That is, the above guide path (500) is formed in a form in which one path branches into two on one side.

In addition, the main body (100) in which the guide channel (500) is formed inside may include a head part (110) in which the power part (M) may be provided either inside or outside, and the first channel (510) that can be connected to the power part (M) so that the flow of culture medium, oocytes, or follicular fluid can be induced by the power generated from the power part (M) is formed inside, and the head part (110) may be formed to extend to one side of the head part (110), and the second channel (520) that is connected to the first channel (510) is formed inside, and may include a grip part (120) that allows a user to stably grip the head part to perform an oocyte retrieval procedure.

At this time, the connection between the first flow path (510) and the power unit (M) can be achieved by, when the power unit (M) is provided inside the head unit (110), the first flow path (510) penetrating the power unit (M), or by connecting one side of the motor of the power unit (M) to one side of the first flow path (510) so that pressure according to the power for suction or discharge can be applied to the first flow path (510).

In addition, when the power unit (M) is provided on the outside of the head unit (110), that is, on the upper surface or side of the head unit (110), a hole is formed so that one side of the first flow path (510) formed inside the head unit (110) and one side of the motor of the power unit (M) are connected, so that pressure according to the power for suction or discharge generated from the power unit (M) is applied to the first flow path (510), thereby enabling the connection between the first flow path (510) and the power unit (M).

At this time, the guide path (500) is configured so that the second path (520) branches off from one side of the first path (510) at the point where the first path (510) and the power unit (M) are connected and communicates with the first path (510), so that when the power unit (M) performs suction driving, pressure according to the suction force generated from the power unit (M) is applied to the second path (520), thereby allowing the flow of the oocytes or follicular fluid sucked through the intubation unit (200) to be directed toward the storage unit (400).

For example, when the first flow path (510) is used as a reference so that the intubation unit (200) and the syringe unit (300) that can be connected to the main body (100), especially the head part (110), can be connected to each other so that the culture medium for washing the follicular fluid can be smoothly moved, after the process of washing the follicular fluid during the oocyte retrieval procedure is completed, during the process of sucking the oocyte or the follicular fluid, before the oocyte or the follicular fluid sucked through the intubation unit (200) and moved along the first flow path (510) reaches the syringe unit (300), the second flow path (520) is connected to one side of the first flow path (510), more specifically, one side of the first flow path (510) located at the point connected to the power unit (M), so that the oocyte or the follicular fluid sucked through the intubation unit (200) can be This is to enable the follicular fluid to be delivered to the storage unit (400).

At this time, as described above, the first flow path (510) connected to the power unit (M) can cause movement of the culture medium and the oocyte or follicular fluid under the influence of the pressure applied by the discharge force and suction force generated from the power unit (M), and it should be recognized that the direction in which the culture medium flows and the direction in which the oocyte or follicular fluid flows in the first flow path (510) are opposite to each other as they are moved by the opposing forces of the discharge force and suction force.

For example, if it is assumed that the flow of the culture medium in the first channel (510) is forward, the flow direction of the oocyte or follicular fluid in the first channel (510) can be seen as reverse.

At this time, the main body (100) may be further equipped with a switching lever (140) that switches the driving direction of the power unit (M) according to the process of spraying the culture solution and the process of sucking the egg or follicular fluid during the egg retrieval procedure, so that the power unit (M) can selectively perform either the ejection drive or the suction drive.

In addition, a blocking unit (G) may be further provided that is linked to the switching lever (140) and, when the power unit (M) is driven to discharge by the operation of the switching lever (140), blocks the communication portion between the first channel (510) and the second channel (520) to prevent the culture medium from flowing into the second channel (520), and, when the power unit (M) is driven to suck by the operation of the switching lever (140), blocks the communication portion between the first channel (510) and the syringe unit (300) to prevent the oocytes or follicular fluid from flowing into the syringe unit (300) and smoothly moving toward the storage unit (400).

This switching lever (140) can be provided at a position where it can be easily operated according to the procedure that the user who has grasped the above-mentioned grip part (120) wants to perform, and the blocking unit (G) connected to the above-mentioned switching lever (140) has one side connected to the above-mentioned switching lever (140) and moves simultaneously with the operation of the above-mentioned switching lever (140), and the other side can be formed in a folded plate shape so that either one of the above-mentioned first flow path (510) and the above-mentioned second flow path (520) can be selectively blocked.

As described above, the process of oocyte retrieval, in which the power unit (M) sprays the culture medium and sucks the oocyte or follicular fluid by operating the switching lever (140) by the user during either the discharge drive or the suction drive, can be more easily understood with reference to FIGS. 2 and 3, and the connection structure of the blocking unit (G) and the switching lever (140) can be more easily understood with reference to FIG. 4.

According to one embodiment of the present invention, the driving lever (130) that controls the driving of the power unit (M) by turning it on/off is preferably provided adjacent to the grip part (120) so that the user can easily operate it while gripping the grip part (120) of the main body (100).

It is preferable that the above-mentioned driving lever (130) be formed in the form of a trigger that swings around a single axis so as to turn the driving of the power unit (M) on/off, and also to enable the output of the power unit (M) to be finely adjusted according to the force of pulling the trigger, that is, the swing angle of the trigger.

For example, when the user puts his finger on the drive lever (130) in the initial position in the form of a trigger and pulls it, the power unit (M) is turned on and driven by the initial force applied, and the power to pull the drive lever (130), that is, when the drive lever (130) is pulled more, increases the output of the power unit (M) in proportion thereto, thereby increasing the intensity of the discharge output and suction force generated from the power unit (M).

Conversely, when the drive lever (130) is pulled and gradually released, the output of the power unit (M) decreases as the drive lever (130) approaches the initial position, so that the intensity of the discharge output and suction force generated from the power unit (M) weakens, and when the drive lever (130) reaches the initial position, the drive of the power unit (M) can be switched to the off state.

By operating the above-mentioned driving lever (130), the user can precisely control the spray amount or spray force of the culture solution and the strength of the suction force for sucking the egg or follicular fluid in real time during the egg retrieval procedure.

At this time, the egg retrieval device according to the present invention is not limited to controlling the output of the power unit (M) by operating the drive lever (130) as described above, and may be provided with a control lever (190) that is provided in the main body (100), more specifically, in the head unit (110), so that the output of the power unit (M) can be controlled by the user's operation, thereby selectively increasing or decreasing the suction power and discharge power generated from the power unit.

The above-mentioned control lever (190) can be linked with the motor of the power unit (M), and the output of the power unit (M) can be controlled by setting a limit on the output that can be produced by the power unit (M) according to the rotation angle of the control lever (190).

For example, by setting the positions where the output of the power unit (M) can be determined as weak (stage 1), medium (stage 2), and strong (stage 3) according to the rotation of the control lever (190), the user can rotate the control lever (190) to the preset positions so that the output required for the oocyte retrieval procedure can be generated, thereby preventing the destruction of the follicle due to excessive output of the power unit (M), or the inability to suck the oocyte or follicular fluid due to weak output.

According to one embodiment of the present invention, in the method for controlling the output of the power unit (M), as described above, either the drive lever (130) or the control lever (190) may be selected and applied, but in order to enable more precise output control and thereby enable more stable oocyte retrieval surgery, the output of the power unit (M) may be adjusted/controlled in a method in which both the operation of the drive lever (130) and the operation of the control lever (190) are applied.

For example, the settings according to weak (stage 1), medium (stage 2), and strong (stage 3) that can be preset in the control lever (190) limit the maximum output that the power unit (M) can produce at each stage, and the user rotates the control lever (190) to produce the output of the desired stage, but the output of the power unit (M) can be more precisely adjusted and controlled according to the degree to which the drive lever (130) is pulled within the output range of the set stage.

In other words, when assuming the total to be 10, the output of the power unit (M) at the weak (stage 1) that can be set is 1 to 3, the output of the power unit (M) at the medium (stage 2) is 4 to 7, and the output of the power unit (M) at the strong (stage 3) is 8 to 10.

At this time, when the output range of the power unit (M) desired by the user is in the middle (stage 2), the user can fix it to the middle (stage 2) by rotating the control lever (190), and the output range of 4 to 7 belonging to the middle (stage 2) is finely adjusted according to the pulling degree of the drive lever (130), but no matter how strongly the drive lever (130) is pulled, the output of the power unit (M) does not exceed 7, and no matter how weakly the pull is made, the output of the power unit (M) does not fall below the strength of 4.

According to one embodiment of the present invention, the drive lever (130) that turns the drive of the power unit (M) on/off and allows the output of the power unit (M) to be finely adjusted is not limited to a trigger shape as described above, and may be formed in the form of a button that allows the user to control the drive and output of the power unit (M) by simply lightly pressing it while holding the grip portion (120).

As described above, the above-described button-shaped drive lever (130) can perform the same function as the trigger-shaped drive lever (130), but if the trigger-shaped drive lever (130) is configured to control the output of the power unit (M) according to the swing angle, the button-shaped drive lever (130) can control the output of the power unit (M) according to the degree of pressure applied by the user.

For example, when the button-shaped driving lever (130) is first pressed, the power unit (M) is turned on and driven, and as the user gradually presses the button-shaped driving lever (130) harder and harder, the degree to which the button-shaped driving lever (130) is inserted into the main body (100) increases, thereby increasing the output of the power unit (M), thereby increasing the strength of the discharge output and suction power generated from the power unit (M).

Conversely, as the user weakens the force with which the button-shaped driving lever (130) is pressed, and the button-shaped driving lever (130) approaches the initial position, the output of the power unit (M) decreases, so that the intensity of the discharge output and suction force generated from the power unit (M) weakens, and when the button-shaped driving lever (130) reaches the initial position, the driving of the power unit (M) is switched to the off state.

At this time, when the button-shaped driving lever (130) is applied, the main body (100) is formed in a 'ㅡ' shape without the grip portion (120) as shown in FIG. 7, so that the overall shape of the egg retrieval device can be made simpler, and it is preferable that the button-shaped driving lever (130) be provided on the side of the main body (100) so that the user can easily operate the button-shaped driving lever (130) while gripping the 'ㅡ'-shaped main body (100).

It should be noted that the above-described button-shaped drive lever (130) can enable the output of the power unit (M) to be more finely controlled in combination with the above-described control lever (190), as mentioned in the embodiment of the above-described trigger-shaped drive lever (130). The method for doing so is the same as the combination of the above-described trigger-shaped drive lever (130) and the above-described control lever (190), so that it can be more easily understood by referring to this.

According to one embodiment of the present invention, the main body (100) may include a fastening part (150) that allows the intubation unit (200) to be detachably coupled.

The above-mentioned fastening member (150) may be provided at the front end of the head portion (110), and may be inserted into one end of the insertion unit (200) so that the first path (510) formed inside the head portion (110) and the insertion unit (200) may be mutually connected, and as the insertion unit (200) is inserted into the vagina of a woman, it may be easily detachable so that it can be sterilized or replaced with a clean one.

To this end, the fastening portion (150) may be formed by including a fastening unit (151) that protrudes and extends from the tip of the head portion (110) and is divided into two, into which one end of the intubation unit (200) can be inserted and fitted into the center, and a joint unit (152) that moves back and forth along the screw threads formed on the fastening unit (151) and allows the fastening unit (151) that is divided into two to come together or spread apart, thereby pressurizing the outer surface of the intubation unit (200) inserted into the fastening unit (151) so that the intubation unit (200) is fastened and fixed, or can be removed for replacement.

At this time, a stopper may be formed protrudingly at one end of the fitting unit (151) to limit the range of movement of the joint unit (152) that is screw-moved along the screw thread formed on the outer surface of the fitting unit (151) and prevent the joint unit (152) from being separated from the fitting unit (151).

As described above, the structure of the fastening portion (150) and the way in which the intubation unit (200) is detachably fastened to the head portion (110) through the fastening portion (150) can be more easily understood with reference to FIGS. 5a and 5b.

As described above, the above-described fastening portion (150) is not limited to a structure formed by a combination of the fitting unit (151) and the joint unit (152), and may be formed by a screw hole structure in which the cannulation unit (200) is forcibly fitted into the fitting groove, or the cannulation unit (200) itself is coupled in a screw manner. However, it is preferable to form a combination of the fitting unit (151) and the joint unit (152) in which the outer surface of the cannulation unit (200) is pressurized and fixed by tightening it so that the cannulation unit (200) is prevented from being indiscriminately detached during the oocyte retrieval procedure, or a structure in which the cannulation unit (200) can be fastened and fixed in a similar manner.

In addition, the main body (100) may be provided at the rear end of the head portion (110), and may further include a coupling portion (160) in which one end of the syringe unit (300) is inserted into the inside of the head portion (110) so that the first flow path (510) formed inside the head portion (110) and the syringe unit (300) are mutually connected.

At this time, the syringe unit (300) corresponds to a general syringe without a needle attached, and a protrusion of the syringe and a part of the body can be inserted into the connecting portion (160) to form a connection.

In addition, the main body (100) may be provided with a connecting portion (170) that protrudes and extends from one side of the grip portion (120), preferably the lower surface of the grip portion (120), so that the upper cover (410) of the storage unit (400) is fitted and connected so that the storage unit (400) is connected to the main body (100).

At this time, it is preferable to form the second channel (520) formed inside the grip part (120) by extending it to the inside of the connecting part (170), so that the second channel (520) and the storage unit (400) can be mutually connected.

In addition, as described above, the connecting portion (170) may be configured to protrude from the lower surface of the grip portion (120) so that the upper cover (410) of the storage unit (400) may be fitted into it, but is not limited thereto. In order to more stably couple the storage unit (400), it is preferable that screw threads are formed along the outer surface of the connecting portion (170), and a connecting hole with screw threads formed on the inner surface of the upper cover (410) is formed so that the storage unit (400) is connected to the connecting portion (170) in a screw manner.

The above-mentioned mounting portion (180) may be made of a metal or synthetic resin material so that, when the storage unit (400) is fitted, it is tightly fitted to surround one side of the outer surface of the storage unit (400) so that the storage unit (400) is fixed to one side of the grip portion (120). Among these, it is preferable that the mounting portion (180) be made of a material having its own elasticity or elastic restoring force so that the storage unit (400) is mounted, but is mounted in a detachable manner so that the storage unit (400) can be easily recovered when the oocyte retrieval procedure is finished.

The structure of the coupling portion (160), the connecting portion (170), the extension unit (C) and the mounting portion (180) having the structure described above and the connection relationship of the syringe unit (300) and the storage unit (400) that are detachably coupled or mounted to the main body accordingly can be more easily understood with reference to FIGS. 6a and 6b.

In addition, the egg retrieval device capable of flushing control according to the present invention can be basically used in a procedure/operation room of a hospital such as an obstetrics and gynecology department, but is not limited thereto, and since it is configured in a compact manner in which both spraying of a culture medium and suctioning of an egg or follicular fluid can be performed with a single device, it is easy to carry and convenient to use in various spaces within a hospital, that is, in other words, in various spaces within a hospital such as a procedure room or an operating room, and in some cases, it should be noted that it can be used for egg retrieval procedures targeting not only humans but also animals in livestock farms or farms or animals in animal hospitals by changing the intubation unit (200).

As described above, preferred embodiments according to the present invention have been examined, and it will be apparent to those skilled in the art that the present invention can be embodied in other specific forms in addition to the embodiments described above without departing from the spirit or scope thereof. Therefore, the above-described embodiments should be considered as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents.
