Description

TECHNICAL FIELD

[0001] The present application relates to the field of suction tubes, in particular to a disposable negative pressure controllable suction tube for artificial abortion. BACKGROUND

[0002] Artificial abortion is a surgical procedure to terminate pregnancy within 12 weeks of gestation, which is used as a remedy for contraceptive failure. Common methods include negative pressure suction artificial abortion, forceps curettage artificial abortion and medical abortion. Negative pressure suction artificial abortion is a frequently used artificial abortion procedure in clinical practice, but it also has the possibility of causing complications during the operation. During negative pressure suction, excessive bleeding, induced abortion syndrome, infertility, and the backflow of some blood into the abdominal cavity may occur due to changes in intrauterine pressure, which can cause endometriosis, which is one of the common causes of female infertility.

[0003] According to the search, Chinese Patent No. CN217338767U discloses a disposable visual artificial abortion suction tube. Although the negative pressure can be controlled by controlling the gripping force, reducing the use of both hands, the doctor's hand needs to apply a gripping force to drive the two clamping pieces to be pressed tightly against each other during use, which is not convenient for automatic fixation of the two clamping pieces, thereby not conducive to freeing the doctor's hands and not conducive to the doctor's surgical operation. SUMMARY

[0004] The purpose of the present application is to provide a disposable negative pressure controllable suction tube for artificial abortion.

[0005] To solve the problems raised in the above background art, the present application provides the following technical solution: a disposable negative pressure controllable suction tube for artificial abortion, comprising a disposable suction tube, an aspiration port is formed in one end of the side wall of the disposable suction tube, a catheter is connected to one end of the disposable suction tube through a connecting structure, a fixed ring is fixedly connected to the outer circumference of the catheter, a fixed block is fixedly connected to one end of the fixed ring, and the fixed block is slidingly connected to the outer circumference of the catheter;

[0006] L-shaped sliding grooves are formed in the two side walls of the fixed block, both L-shaped sliding grooves are in communication with the catheter, and extrusion plates are slidingly connected in both L-shaped sliding grooves. One end of each of the two extrusion plates abuts against the side wall of the catheter, and drive plates are fixedly connected to the side walls of the two extrusion plates. The two drive plates are slidingly connected in the two L-shaped sliding grooves, two first springs are fixedly connected to the side walls of the two drive plates, and four first springs are fixedly connected to the side walls of the two L-shaped sliding grooves. The side walls of the two drive plates are provided with extrusion structures.

[0007] Two toothed racks are fixedly connected to the top of the two extrusion plates, two limiting plates are slidably connected to the top of the fixed block, the bottom of the two limiting plates is arranged in an inclined manner, the bottom of the two limiting plates penetrates the fixed block and abuts against the top of the two toothed racks respectively, the top of the two limiting plates is fixedly connected with a pull plate, the bottom of the pull plate is fixedly connected with two second springs, and the bottom of the two second springs is fixedly connected to the top side wall of the fixed block.

[0008] By pressing the two driving plates, the two driving plates simultaneously drive the extrusion plates to move relative to each other, so that the two extrusion plates extrude the catheter, thereby controlling the negative pressure in the catheter. When the two extrusion plates move, the toothed racks can be moved. When the toothed racks move, the inclined side walls of the limiting plates can be extruded, so that the limiting plates move along the inclined side walls of the toothed racks. At this time, the limiting plates drive the second springs to move through the pull plate, so that the two second springs are in a stressed state. Under the action of the two second springs, one end of the two limiting plates can always abut against the side walls of the two toothed racks. Because the inclined side walls of the limiting plates and the inclined side walls of the toothed racks are extruded only when the extrusion plates move towards the catheter, when the extrusion plates move away from the catheter, the limiting plates will lock the toothed racks, so that the extrusion plates cannot move. Therefore, when the two extrusion plates extrude the catheter, the limiting plates can automatically fix the extrusion plates, so that the extrusion plates continuously extrude the catheter, thereby maintaining the pressure in the catheter. The doctor does not need to press the driving plate all the time, thereby freeing the doctor's hands and facilitating the doctor's operation. By lifting the pull ring, the two limiting plates can be moved to disengage from the top of the toothed racks. Under the action of the two first springs, the two extrusion plates can be automatically reset.

[0009] As a further scheme of the application, the connecting structure comprises a connecting head fixedly connected to one end of the side wall of the disposable suction tube, the connecting head is provided in the form of an elastic hose, the side wall of the catheter is fixedly connected with an externally threaded tube, the externally threaded tube is threadedly connected with an internally threaded ring on the outer circumferential side wall, the outer circumferential side wall of the externally threaded tube is slidably connected with an extrusion tube, the inner circumferential side wall of one end of the extrusion tube is fixedly connected with an extrusion ring, the side wall of the externally threaded tube is fixedly connected with a sleeve, the outer circumferential side wall of the sleeve is fixedly connected with a limiting ring, the limiting ring is arranged in an inclined manner on both sides, and the connecting head is sleeved on the outer circumferential side wall of the sleeve.

[0010] By sleeving the connecting head at one end of the disposable suction tube on the outer wall side of the sleeve and the limiting ring, then rotating the inner threaded ring, the inner threaded ring moves on the surface of the outer threaded tube, and the inner threaded ring will extrude the extrusion tube when moving, so that the extrusion tube moves towards the limiting ring, and the extrusion tube drives the extrusion ring to move at the same time, so that the extrusion ring abuts against the side wall of the limiting ring, thereby extruding and fixing the connecting head, maintaining the stability of the connecting head when connected with the sleeve, thereby completing the installation of the disposable suction tube, and different models of disposable suction tubes can be selected for installation according to the model of the disposable suction tube required during surgery, so as to facilitate precise matching of individual differences of patients and surgical requirements, improve the functionality of the device, and after use, the disposable suction tube entering the human body can be discarded.

[0011] As a further scheme of the application: the outer wall side of the inner threaded ring is provided with anti-skid teeth.

[0012] As a further scheme of the application: the extrusion ring is arranged in a circular ring shape, and the circular ring side wall of the extrusion ring is in close contact with the inclined side wall of the limiting ring.

[0013] As a further scheme of the application: the two extrusion structures include two lever rods, the two lever rods are respectively rotationally connected to the side walls of the two L-shaped sliding grooves, the two lever rods are in close contact with the two driving plates, the side walls of the two L-shaped sliding grooves are fixedly connected with baffle plates, the two lever rods are respectively located between the driving plates and the baffle plates, one end of each of the two lever rods is fixedly connected with a push block, by pressing the two push blocks, the two push blocks drive the lever rods to rotate, so that the lever rods extrude the two driving plates to move, compared with directly pressing the two driving plates, the extrusion of the two lever rods on the driving plates is more labor-saving by using the principle of lever.

[0014] As a further scheme of the application: the two push blocks are made of anti-skid rubber material.

[0015] As a further scheme of the application: the pull plate is fixedly connected with a pull ring at the top.

[0016] As a further scheme of the application: the disposable suction tube is fixedly connected with a high-definition camera at one end, and the high-definition camera is arranged in a CMOS camera.

[0017] Compared with the prior art, the application has the following advantages:

[0018] 1、In use, by pressing the two drive plates, the two drive plates simultaneously drive the extrusion plates to move relative to each other, so that the two extrusion plates extrude the catheter, thereby controlling the negative pressure in the catheter. When the two extrusion plates move, the rack can be driven to move. When the rack moves, it can extrude the inclined side wall of the limiting plate, so that the limiting plate moves along the inclined side wall of the rack. At this time, the limiting plate drives the second spring to move through the pull plate, so that the two second springs are in a stressed state. Under the action of the two second springs, the one end of the two limiting plates is always pressed against the side wall of the two racks. Because the inclined side wall of the limiting plate and the inclined side wall of the rack are extruded only when the extrusion plate moves towards the catheter, the limiting plate will lock the rack when the extrusion plate moves away from the catheter, so that the extrusion plate cannot move. Therefore, when the two extrusion plates extrude the catheter, the limiting plate can automatically fix the extrusion plate, so that the extrusion plate continuously extrudes the catheter, thereby maintaining the pressure in the catheter. The doctor does not need to press the drive plate all the time, thereby freeing the doctor's hands and facilitating the doctor's operation. By lifting the pull ring, the two limiting plates can be driven to move, so that the two limiting plates are separated from the top of the rack. Under the action of the two first springs, the two extrusion plates can be automatically reset.

[0019] 2、By pressing the two drive plates, the two drive plates drive the lever to rotate, so that the lever extrudes the two drive plates to move. Compared with directly pressing the two drive plates, the extrusion of the two levers on the drive plate is more labor-saving.

[0020] 3、By pressing the two drive plates, the two drive plates drive the lever to rotate, so that the lever extrudes the two drive plates to move. Compared with directly pressing the two drive plates, the extrusion of the two levers on the drive plate is more labor-saving. BRIEF DESCRIPTION OF DRAWINGS

[0041] Embodiment 3

[0042] Please refer to Figures 1-2 , Figures 5-6 The application provides a technical scheme: a disposable artificial abortion negative pressure controllable suction tube, two squeeze structures comprising two lever rods 11, the two lever rods 11 are rotatably connected to the side walls of two L-shaped sliding grooves 22 respectively, the two lever rods 11 are matched with two driving plates 20, the side walls of the two L-shaped sliding grooves 22 are fixedly connected with baffle plates 12, the two lever rods 11 are located between the driving plates 20 and the baffle plates 12 respectively, and one end of each of the two lever rods 11 is fixedly connected with a poking block 9.

[0043] Please refer to Figures 1-2 , Figures 5-6 The two poking blocks 9 are made of anti-skid rubber material.

[0044] Specifically, by pressing the two knobs 9, the two knobs 9 drive the rocker bars 11 to rotate, so that the rocker bars 11 extrude the two driving plates 20 to move. Compared with directly pressing the two driving plates 20, the extrusion of the two rocker bars 11 on the driving plates 20 is more labor-saving by the principle of leverage.

[0045] The working principle and use process of the application: when using the device, the high-definition camera 2 provided can provide real-time images with a resolution of 1080P, clearly showing the intrauterine pregnancy tissue, decidua and endometrial boundary, so that the one-end of the disposable suction tube 1 can quickly reach the specified position in the uterus, facilitating the suction operation during the operation. Then, by pressing the two driving plates 20, the two driving plates 20 simultaneously drive the extrusion plates 19 to move relative to each other, so that the two extrusion plates 19 extrude the catheter 10, thereby controlling the negative pressure in the catheter 10. When the two extrusion plates 19 move, the rack 18 can be driven to move, and the rack 18 can extrude the inclined side wall of the limiting plate 25 when moving, so that the limiting plate 25 moves along the inclined side wall of the rack 18.

Under the action of the two second springs 24, the one-end of the two limiting plates 25 can always abut against the side wall of the two racks 18. Because the inclined side wall of the limiting plate 25 and the inclined side wall of the rack 18 are extruded when the extrusion plate 19 moves towards the catheter 10, when the extrusion plate 19 moves away from the catheter 10, the limiting plate 25 will clamp the rack 18, so that the extrusion plate 19 cannot move.

Under the action of the two first springs 21, the two extrusion plates 19 can be automatically reset.

[0046] By pressing the two knobs 9, the two knobs 9 drive the rocker bars 11 to rotate, so that the rocker bars 11 extrude the two driving plates 20 to move. Compared with directly pressing the two driving plates 20, the extrusion of the two rocker bars 11 on the driving plates 20 is more labor-saving by the principle of leverage.

[0047] By sleeving the connecting head 3 at one end of the disposable suction tube 1 on the outer circle sidewall of the sleeve 4 and the limiting ring 17, then rotating the inner threaded ring 6, the inner threaded ring 6 moves on the surface of the outer threaded tube 16, and the inner threaded ring 6 extrudes the extrusion tube 5 to move when moving, so that the extrusion tube 5 moves to the limiting ring 17, and the extrusion tube 5 drives the extrusion ring 15 to move at the same time, so that the extrusion ring 15 abuts against the sidewall of the limiting ring 17, thereby extruding and fixing the connecting head 3, maintaining the stability of the connecting head 3 and the sleeve 4 when connected, thereby completing the installation of the disposable suction tube 1, and different models of disposable suction tubes 1 can be selected and installed according to the model of the disposable suction tube 1 required during the operation, so as to facilitate precise matching of individual differences of patients and operation requirements, improve the functionality of the device, and after use, the disposable suction tube 1 entering the human body can be discarded.

[0048] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the application, and still fall within the protection scope of the application.
