Description

Technical Field

[0001] The present invention relates to the technical field of obstetrics and gynecology, and particularly relates to a delivery assistor for obstetrics and its usage method. Background Technique

[0002] Forceps is an instrument that can be used to assist parturient women in delivering babies. Forceps delivery is one of the important means to solve cephalic dystocia, shorten the second stage of labor, and terminate pregnancy as soon as possible. Forceps consists of two branches (blades) that are placed around the fetal head. These branches are defined as the left lobe and the right lobe according to which side of the mother's pelvis they are applied to. The branches usually (but not always) cross at the midpoint of the joint. Most forceps have a locking structure at the joint, but a few forceps have a sliding structure that allows the two branches to slide along each other. Forceps with a fixed locking structure are used for deliveries that require little or no rotation, such as when the fetal head is aligned with the mother's pelvis. Forceps with a sliding locking structure are used for deliveries that require more rotation. The blade of each forceps branch is a curved part for grasping the fetal head. The forceps should firmly surround the fetal head but not be too tight. The blade has two curves, namely the fetal head curve and the pelvic curve. The shape of the head curve conforms to the fetal head. According to the shape of the fetal head, the head curve can be circular or more elongated. The shape of the pelvic curve conforms to the birth canal and helps to guide the traction under the pubis. Forceps used for rotating the fetal head have almost no pelvic curve.

[0003] After retrieval, the patent with the application number CN202210287646.7 discloses a "device for assisting the delivery of the fetal head during cesarean section" for obstetricians, including: a control rod, and a head carrier is fixedly installed at the front end of the control rod; shaft rods are rotatably installed on the left and right sides of the head carrier, and the shaft rods are cylindrical structures; a draw rod is slidably inserted at the front end of the head carrier.

[0004] However, in the use of the above device, since a large amount of body fluids (such as blood) and other viscous body fluids are inevitably generated during the delivery of pregnant women, when the staff operates, the body fluids of the pregnant women are easily splashed or brought onto the surface of the control box, and when the staff pushes the control box, it is easy to slip, resulting in inconvenience in use. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that since a large amount of body fluids (such as blood) and other viscous body fluids are inevitably generated during the delivery of pregnant women, when the staff operates, the body fluids of the pregnant women are easily splashed or brought onto the surface of the control box, and when the staff pushes the control box, it is easy to slip, resulting in inconvenience in use, and to propose a delivery assistor for obstetrics and its usage method.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: An obstetric delivery aid, including clamping pliers, with a head suction cup provided between the clamping pliers; There is also a limiting mechanism for limiting the angle of the clamping pliers. The limiting mechanism includes a gear fixedly installed on the front side of the clamping pliers. A support frame is rotatably installed on the outer side of the gear. A double-sided rack is meshed between the gears. The double-sided rack is slidably installed on the support frame. A screw rod is threadedly installed on the front side of the double-sided rack. Both the front and rear ends of the screw rod are rotatably installed on the support frame. A rotary knob is fixedly installed on the front side of the screw rod; There is also an anti-adhesion mechanism for preventing body fluids from adhering to the rotary knob during a pregnant woman's delivery. The anti-adhesion mechanism includes a baffle fixedly installed corresponding to the rotary knob at the upper end of the support frame, and a flexible cleaning ring is provided at the rear side of the rotary knob.

[0007] Preferably, the rigid tube on the head suction cup is fixedly installed on the support frame, and the other end of the rigid tube is connected to a negative pressure suction device.

[0008] Preferably, anti-slip grooves are provided on the outer side of the rotary knob, and a limit block is snap-fitted corresponding to the anti-slip grooves at the right end of the rotary knob. The lower end of the limit block is slidably installed on the support frame.

[0009] Preferably, a first spring is fixedly installed at the right end of the limit block. The right end of the first spring is fixedly installed with a vertical plate. The lower end of the vertical plate is fixedly installed on the support frame, and an anti-loosening block is slidably installed between the upper end of the support frame and the limit block and the vertical plate.

[0010] Preferably, a connecting rod is fixedly installed at the rear end of the flexible cleaning ring. The rear end of the connecting rod penetrates and is slidably installed on the baffle. A magnetic sheet is fixedly installed at the rear end of the connecting rod. A second spring is sleeved on the outer side of the connecting rod. The front and rear ends of the second spring are respectively fixedly connected to the baffle and the magnetic sheet.

[0011] Preferably, a magnetic strip is provided at the rear side of the magnetic sheet. The front end of the magnetic strip is fixedly connected to the limit block, and the magnetic sheet and the magnetic strip are mutually magnetically repulsive.

[0012] Preferably, a sweeping strip is provided on the upper front side of the flexible cleaning ring. The upper end of the sweeping strip is fixedly installed with a hollow rod. Nozzles are provided at the lower end and the inner side end of the sweeping strip.

[0013] Preferably, the upper end of the hollow rod penetrates and is slidably installed on the baffle. A pressing plate is fixedly installed at the upper end of the hollow rod. A third spring is sleeved on the outer side of the hollow rod.

[0014] Preferably, an airbag is fixedly installed at the lower end of the pressing plate. The lower end of the airbag is fixedly installed on the baffle. A connecting pipe is communicated at the upper end of the airbag. The other end of the connecting pipe is mutually communicated with the inside of the hollow rod, and the lower end of the hollow rod is communicated with the nozzle.

[0015] A method for using an obstetric delivery aid is as follows: Step 1: The staff member holds the handle at the front end of the support frame with one hand, and pushes the anti-loosening block to separate the limit block from the rotary knob. Step 2: Use the thumb to rotate the rotary knob to make the clamping pliers on both sides move closer or farther away from each other synchronously, and adjust the angle of the clamping pliers. Step 3: In Step 1, when the limit block slides, it drives the magnetic strip to slide synchronously, generates a magnetic thrust on the magnetic sheet, and pushes the flexible cleaning ring forward to clean the body fluid on the rotary knob. Step 4: Press down the pressing plate, and use the sweeping strip to sweep the body fluid adhering to the outer surface of the flexible cleaning ring to the lower side. Step 5: The gas in the airbag passes through the inside of the connecting pipe and the hollow rod, and finally sprays out from the nozzle, which can cooperate with the sweeping strip to spray the body fluid that is difficult to remove on it.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, when the staff member holds the handle at the front end of the support frame with one hand and needs to adjust the opening and closing angle of the clamping pliers, the thumb first pushes the anti-loosening block backward. The anti-loosening block separates from the limit block and the vertical plate. Under the action of the first spring, the limit block is pulled to slide to the right and reset, so that the limit block is separated from the rotary knob. Then use the thumb to rotate the rotary knob to drive the screw to rotate. The screw drives the double-sided rack to move back and forth, thereby driving the gears on both sides to rotate. The gears drive the clamping pliers on both sides to rotate synchronously, so that the clamping pliers on both sides move closer or farther away from each other synchronously, which is convenient to adjust the angle of the clamping pliers according to actual needs, and can be operated with one hand, improving work efficiency.

[0017] 2. In the present invention, when the anti-loosening block is pushed backward, the inclined surface of the anti-loosening block squeezes the edge of the limit block, which will drive the limit block to move to the left, stretching the first spring. When the horizontal planes at the left and right ends of the anti-loosening block are in contact with the limit block and the vertical plate respectively, stop pushing the anti-loosening block. The anti-loosening block effectively realizes the reset of the limit block. The clamping plate at the left end of the limit block is clamped on the anti-slip groove on the rotary knob to realize the limit of the rotary knob and prevent the situation that it is accidentally touched and rotated to drive the screw, thereby avoiding the situation that the screw rotates to drive the double-sided rack to move back and forth, which is convenient to ensure the fixing of the angle of the clamping pliers.

[0018] 3. In the present invention, the provided baffle is beneficial to prevent the body fluid (such as blood, etc.) generated by the pregnant woman from splashing or adhering to the rotary knob during childbirth, resulting in the situation that it is difficult to rotate due to slipping when the staff operates the rotary knob, thereby ensuring that the clamping pliers can be adjusted smoothly.

[0019] 4. In the present invention, when the baffle cannot effectively block the pregnant woman's body fluid, when the limiting block is reset under the pulling force of the first spring, it will also drive the magnetic strip to move synchronously to the right. The magnetic pole of the magnetic strip will pass through the rear side of the magnetic sheet, thereby generating a magnetic repulsive force to push the magnetic sheet forward. The magnetic sheet drives the connecting rod and the flexible cleaning ring to move forward synchronously, compressing the second spring. The diameter of the second spring is smaller than that of the first spring. The provided flexible cleaning ring is convenient for cleaning and adsorbing the pregnant woman's body fluid adhering to the outer surface of the rotary knob, ensuring the cleanliness of the outer surface of the rotary knob and ensuring that the staff can smoothly rotate the rotary knob.

[0020] 5. In the present invention, when the magnetic strip passes over the rear side of the magnetic sheet, the second spring drives the magnetic sheet, the connecting rod and the flexible cleaning ring to reset, without affecting the staff's rotation of the rotary knob.

[0021] 6. In the present invention, when the thumb presses down the pressing plate, it drives the hollow rod and the sweeping strip to descend synchronously, compressing the third spring and the airbag. The provided sweeping strip is convenient for sweeping the body fluid adhering to the outer surface of the flexible cleaning ring to the lower side, which is beneficial to reducing the situation that a large amount of body fluid adheres to the flexible cleaning ring and causes re-adhesion to the rotary knob.

[0022] 7. In the present invention, the gas in the airbag passes through the inside of the connecting pipe and the hollow rod and finally sprays out from the nozzle. When the sweeping strip sweeps the body fluid on the outer surface of the flexible cleaning ring, it can also spray the body fluid that is difficult to remove and adheres to the flexible cleaning ring, which is beneficial to improving the sweeping effect of the body fluid adhering to the flexible cleaning ring.

[0026] Referring to Figures 1 - 8 , an obstetric delivery aid, including clamping pliers 1, a head suction cup 101 is arranged between the clamping pliers 1; a limit mechanism for limiting the angle of the clamping pliers 1 is also provided, and the limit mechanism includes a gear 2 fixedly installed on the front side of the clamping pliers 1, a support frame 3 is rotatably installed on the outer side of the gear 2, a double-sided rack 4 is engaged between the gears 2, the double-sided rack 4 is slidably installed on the support frame 3, a screw 5 is threadedly installed on the front side of the double-sided rack 4, both the front and rear ends of the screw 5 are rotatably installed on the support frame 3, a knob 6 is fixedly installed on the front side of the screw 5, a hard pipe on the head suction cup 101 is fixedly installed on the support frame 3, and the other end of the hard pipe is connected to a negative pressure suction device, anti-slip threads are provided on the outer side of the knob 6, a limit block 7 is clamped corresponding to the anti-slip threads at the right end of the knob 6, the lower end of the limit block 7 is slidably installed on the support frame 3, a first spring 8 is fixedly installed at the right end of the limit block 7, a vertical plate 9 is fixedly installed at the right end of the first spring 8, the lower end of the vertical plate 9 is fixedly installed on the support frame 3, and an anti-loosening block 901 is slidably installed between the upper end of the support frame 3 and the limit block 7; During operation, the operator holds the handle at the front end of the support frame 3 with one hand. When it is necessary to adjust the opening and closing angle of the clamping pliers 1, the thumb first pushes the anti-loosening block 901 backward. The anti-loosening block 901 separates from the limit block 7 and the vertical plate 9. Under the action of the first spring 8, the limit block 7 is pulled to slide to the right and reset, so that the limit block 7 separates from the rotary knob 6. Then, the thumb is used to rotate the rotary knob 6 to drive the screw rod 5 to rotate. The screw rod 5 drives the double-sided rack 4 to move back and forth, thereby driving the gears 2 on both sides to rotate. The gears 2 drive the clamping pliers 1 on both sides to rotate synchronously, so that the clamping pliers 1 on both sides approach or move away from each other synchronously, which is convenient for adjusting the angle of the clamping pliers 1 according to actual needs, and can be operated with one hand, improving work efficiency. After the adjustment is completed, the anti-loosening block 901 is pushed backward. The inclined surface of the anti-loosening block 901 presses the edge of the limit block 7, which will drive the limit block 7 to move to the left, stretching the first spring 8. When the horizontal planes at the left and right ends of the anti-loosening block 901 are in contact with the limit block 7 and the vertical plate 9 respectively, stop pushing the anti-loosening block 901. The anti-loosening block 901 effectively realizes the reset of the limit block 7. The left clamping plate of the limit block 7 is clamped on the anti-slip groove on the rotary knob 6 to limit the rotary knob 6 and prevent it from accidentally touching and rotating to drive the screw rod 5, thus avoiding the situation where the screw rod 5 rotates to drive the double-sided rack 4 to move back and forth, which is convenient for ensuring the fixation of the angle of the clamping pliers 1.

[0027] As an embodiment of the present invention, an anti-sticking mechanism is also provided to prevent the body fluids during pregnant women's childbirth from adhering to the rotary knob 6. The anti-sticking mechanism includes a baffle 10 fixedly installed corresponding to the rotary knob 6 at the upper end of the support frame 3. A flexible cleaning ring 11 is provided at the rear side of the rotary knob 6. A connecting rod 12 is fixedly installed at the rear end of the flexible cleaning ring 11. The rear end of the connecting rod 12 is slidably installed through the baffle 10. A magnetic sheet 13 is fixedly installed at the rear end of the connecting rod 12. A second spring 14 is sleeved on the outer side of the connecting rod 12. The front and rear ends of the second spring 14 are fixedly connected to the baffle 10 and the magnetic sheet 13 respectively. A magnetic strip 15 is provided at the rear side of the magnetic sheet 13. The front end of the magnetic strip 15 is fixedly connected to the limit block 7. The magnetic sheet 13 and the magnetic strip 15 are magnetically repulsive to each other. A sweeping strip 16 is provided on the upper front side of the flexible cleaning ring 11. A hollow rod 18 is fixedly installed at the upper end of the sweeping strip 16. Nozzles 17 are provided at the lower end and the inner end of the sweeping strip 16. The upper end of the hollow rod 18 is slidably installed through the baffle 10. A pressing plate 19 is fixedly installed at the upper end of the hollow rod 18. A third spring 22 is sleeved on the outer side of the hollow rod 18. An airbag 20 is fixedly installed at the lower end of the pressing plate 19. The airbag 20 is fixedly installed on the baffle 10 at the lower end. The upper end of the airbag 20 is communicated with a connecting pipe 21. The other end of the connecting pipe 21 is communicated with the inside of the hollow rod 18, and the lower end of the hollow rod 18 is communicated with the nozzle 17. During operation, the provided baffle 10 helps prevent body fluids (such as blood) produced by a pregnant woman from splashing or adhering to the rotary knob 6 during childbirth, which may cause slippage and difficulty in rotation when the staff operates the rotary knob 6, thus ensuring the smooth adjustment of the clamping pliers 1. If the baffle 10 fails to effectively block the body fluids of the pregnant woman, when the limit block 7 is reset under the pulling force of the first spring 8, it will also drive the magnetic strip 15 to move synchronously to the right. The magnetic pole of the magnetic strip 15 will pass by the rear side of the magnetic sheet 13, thereby generating a magnetic repulsive force to push the magnetic sheet 13 forward. The magnetic sheet 13 drives the connecting rod 12 and the flexible cleaning ring 11 to move forward synchronously, compressing the second spring 14. The diameter of the second spring 14 is smaller than that of the first spring 8. The provided flexible cleaning ring 11 facilitates the cleaning and adsorption of the body fluids adhered to the outer surface of the rotary knob 6, ensuring the cleanliness of the outer surface of the rotary knob 6 and enabling the staff to smoothly rotate the rotary knob 6. When the magnetic strip 15 passes over the rear side of the magnetic sheet 13, the second spring 14 drives the magnetic sheet 13, the connecting rod 12, and the flexible cleaning ring 11 to reset, without affecting the staff's rotation of the rotary knob 6. Press the pressing plate 19 downward with the thumb to drive the hollow rod 18 and the sweeping strip 16 to descend synchronously, compressing the third spring 22 and the airbag 20. The provided sweeping strip 16 facilitates sweeping the body fluids adhered to the outer surface of the flexible cleaning ring 11 to the lower side, which helps reduce the situation of a large amount of body fluids adhering to the flexible cleaning ring 11 and causing re - adhesion to the rotary knob 6. Meanwhile, the gas in the airbag 20 passes through the connecting pipe 21 and the inside of the hollow rod 18 and finally sprays out from the nozzle 17, which can spray the body fluids that are difficult to remove and adhered to the flexible cleaning ring 11 when the sweeping strip 16 sweeps the body fluids on the outer surface of the flexible cleaning ring 11, helping to improve the sweeping effect of the body fluids adhered to the flexible cleaning ring 11.

[0028] A method for using an obstetric delivery aid is as follows: Step 1: The staff holds the front handle of the support frame 3 with one hand and pushes the anti - loosening block 901 to separate the limit block 7 from the rotary knob 6. Step 2: Use the thumb to rotate the rotary knob 6 to make the two clamping pliers 1 approach or move away from each other synchronously to adjust the angle of the clamping pliers 1. Step 3: In Step 1, when the limit block 7 slides, it drives the magnetic strip 15 to slide synchronously, generating a magnetic thrust on the magnetic sheet 13 to push the flexible cleaning ring 11 forward to clean the body fluids on the rotary knob 6. Step 4: Press the pressing plate 19 downward to sweep the body fluids adhered to the outer surface of the flexible cleaning ring 11 to the lower side through the sweeping strip 16. Step 5: The gas in the airbag 20 passes through the connecting pipe 21 and the inside of the hollow rod 18 and finally sprays out from the nozzle 17, which can cooperate with the sweeping strip 16 to spray the body fluids that are difficult to remove and adhered above.

[0029] Working principle: When the present invention is used, the staff holds the handle at the front end of the support frame 3 with one hand. When it is necessary to adjust the opening and closing angle of the clamping pliers 1, the thumb first pushes the anti-loosening block 901 backwards, and the anti-loosening block 901 is separated from the limit block 7 and the vertical plate 9. Under the action of the spring 1 8, the limit block 7 is pulled to slide to the right and reset, so that the limit block 7 is separated from the knob 6, and then the thumb is used to rotate the knob 6 to drive the screw 5 to rotate, and the screw 5 drives the double-sided rack 4 to move back and forth, thereby driving the gears 2 on both sides to rotate, and the gears 2 drive the clamping pliers 1 on both sides to rotate synchronously, so that the clamping pliers 1 on both sides are synchronously close to or away from each other, so that it is convenient to adjust the angle of the clamping pliers 1 according to actual needs, and it can be operated with one hand, thereby improving work efficiency; After the adjustment is completed, the anti-loosening block 901 is pushed to move backward, and the inclined surface of the anti-loosening block 901 squeezes the corner of the limit block 7, which will drive the limit block 7 to move to the left, stretching the spring 8. When the horizontal surfaces of the left and right ends of the anti-loosening block 901 contact the limit block 7 and the vertical plate 9 respectively, the anti-loosening block 901 stops pushing the anti-loosening block 901, and the anti-loosening block 901 effectively realizes the reset of the limit block 7. The left end card of the limit block 7 is connected to the anti-slip texture on the knob 6 to limit the knob 6 and prevent it from accidentally touching the rotation to drive the screw 5, thereby avoiding the situation where the screw 5 rotates to drive the double-sided rack 4 to move back and forth, which is convenient for ensuring the fixing of the angle of the clamp 1; At the same time, the baffle 10 is helpful to prevent the body fluids (such as blood, etc.) produced by the pregnant woman during childbirth from splashing or adhering to the knob 6, causing the knob 6 to slip and become difficult to rotate when the staff operates it, thereby ensuring that the clamp 1 can be adjusted smoothly; If the baffle 10 cannot effectively block the pregnant woman's body fluid, when the limit block 7 is reset by the pulling force of the spring 18, it will also drive the magnetic strip 15 to move to the right synchronously, and the magnetic pole of the magnetic strip 15 will pass the rear side of the magnetic sheet 13, thereby generating a magnetic repulsive force, pushing the magnetic sheet 13 to move forward, and the magnetic sheet 13 drives the connecting rod 12 and the flexible cleaning ring 11 to move forward synchronously, compressing the spring 2 14. The diameter of the spring 2 14 is smaller than that of the spring 1 8. The flexible cleaning ring 11 is convenient for cleaning and absorbing the pregnant woman's body fluid adhered to the outer surface of the knob 6, ensuring the cleanliness of the outer surface of the knob 6, and ensuring that the staff can smoothly turn the knob 6; When the magnetic strip 15 passes over the rear side of the magnetic sheet 13, the spring 2 14 drives the magnetic sheet 13, the connecting rod 12 and the flexible cleaning ring 11 to reset, without affecting the staff member's rotation of the knob 6. The thumb presses the pressing plate 19 downward, driving the hollow rod 18 and the sweeping strip 16 to descend synchronously, compressing the spring 3 22 and the air bag 20. The sweeping strip 16 is arranged to sweep the body fluid adhering to the outer surface of the flexible cleaning ring 11 to the lower side, which is conducive to reducing the body fluid from adhering to the flexible cleaning ring 11 in large quantities, causing it to adhere to the knob 6 again. Meanwhile, the gas in the airbag 20 passes through the inside of the connecting pipe 21 and the hollow rod 18, and finally sprays out from the nozzle 17. When the sweeping strip 16 sweeps the body fluid on the outer surface of the flexible cleaning ring 11, it can also spray the body fluid that is difficult to remove and adheres to the flexible cleaning ring 11, which is beneficial to improving the sweeping effect of the body fluid adhering to the flexible cleaning ring 11.
