Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an adjustable forceps for assisting clinical childbirth in obstetrics and gynecology. Background Technology

[0002] Forceps are a medical instrument used when a pregnant woman experiences dystocia (difficult labor). They are used to assist doctors in removing the baby from the birth canal when necessary.

[0003] For example, Chinese patent CN111557718B discloses a gynecological assisted delivery device. The device includes a forceps body, which includes two cross-arranged forceps bodies. Each forceps body includes a forceps head, forceps arms, and forceps handles. The forceps head, forceps arms, and forceps handles are connected in sequence. The outer surface of the forceps head is covered with a silicone sleeve. The two forceps heads are used together to clamp the fetal head. The two forceps arms are oscillatingly connected, and the two forceps handles are elastically connected. The forceps handles are used to receive force and drive the forceps arms and forceps heads to oscillate in order to clamp the fetal head.

[0004] However, the forceps body surface in the above scheme cannot completely contact the baby's head, which will lead to excessive local pressure on the forceps and may cause injury to the baby. In addition, because there is a certain amount of mucus or other substances at the contact point between the baby's head and the forceps, the contact friction between the forceps and the baby's head will be reduced, thereby reducing the stability of the forceps body. Summary of the Invention

[0005] Therefore, it is necessary to provide an adjustable forceps for clinical obstetric delivery assistance, which addresses the problem that current forceps cannot fully fit the baby's head and have poor stability when holding the baby's head.

[0006] The above objectives are achieved through the following technical solutions: An adjustable forceps for assisting childbirth in obstetric and gynecological clinical practice includes: The forceps body includes two intersecting forceps bodies. Each forceps body has a forceps head, forceps arm, and forceps handle. The forceps head has an arc-shaped structure, and grooves are formed on the surfaces of the two forceps heads that are close to each other. A first water bladder and a second water bladder, both of which are located within the groove, with the first water bladder located outside the second water bladder; An airbag is located between the first water bladder and the second water bladder. The airbag can push the first and second water bladders out of the groove to contact the baby's head and push the first and second water bladders away from each other. A negative pressure assembly that creates negative pressure in the cavity between the first and second water bladders to absorb the baby's head. A locking assembly that can lock the handles of the two clamps in a preset position.

[0007] Furthermore, the clamp handle has an internal receiving cavity that communicates with the airbag. A first piston is slidably disposed within the receiving cavity, and a first limiting block is slidably disposed within the receiving cavity. The sliding direction of the first limiting block is perpendicular to the sliding direction of the first piston.

[0008] Furthermore, the negative pressure assembly includes a negative pressure chamber and a second piston. The negative pressure chamber is located inside the clamp handle, and an annular cavity is located inside the clamp head. The annular cavity communicates with the negative pressure chamber and with the cavity between the first water bladder and the second water bladder. The second piston is slidably and sealed inside the negative pressure chamber. A second limiting block is slidably disposed inside the negative pressure chamber. The sliding direction of the second limiting block is perpendicular to the sliding direction of the first piston and the sliding direction of the second piston.

[0009] Furthermore, a connecting hole is provided at the bottom of the groove, and the connecting hole communicates with the annular cavity.

[0010] Furthermore, the bottom of the groove is provided with a first mounting groove and a second mounting groove, a first mounting plate is fixedly connected to the outer peripheral sidewall of the first water bladder, the first mounting plate is engaged in the first mounting groove, a second mounting plate is fixedly provided on the outer peripheral sidewall of the second water bladder, the second mounting plate is engaged in the second mounting groove, a third mounting groove is provided between the first mounting groove and the second mounting groove, and the air bladder is located in the third mounting groove.

[0011] Furthermore, the thickness of the airbag at the position where it contacts the sidewall of the third mounting groove is thinner than the thickness at the position where it does not contact the sidewall of the third mounting groove.

[0012] Furthermore, a corrugated tube is provided between the first water bladder and the second water bladder, with one end of the corrugated tube connected to the first water bladder and the other end of the corrugated tube connected to the second water bladder.

[0013] Furthermore, a pressure sensor is installed inside the bellows to detect the water pressure inside the bellows, and a display screen is installed on the handle, with the pressure sensor electrically connected to the display screen.

[0014] Furthermore, the locking assembly includes a latch, a pull rope, a hook, and a feed roller. The latch and the feed roller are respectively mounted on two clamp handles. One end of the pull rope is wrapped around the outer periphery of the feed roller, and the hook is connected to the other end of the pull rope. The pull rope is connected to the latch through the hook.

[0015] Furthermore, a locking block is provided on the clamp handle, which can move radially along the pay-off roller to restrict or unlock the pay-off roller.

[0016] The beneficial effects of this invention are: This invention features a clamp head with an arc-shaped structure that adapts to the contour of the baby's head. Grooves are formed on the surfaces of the two clamp heads that are close to each other. The first and second water bladders in the grooves are elastic. When the air bladders are inflated, they push the water bladders out of the grooves and fit against the baby's head. The clamp head can adapt to the shape of the baby's head and deform accordingly, avoiding excessive local pressure caused by hard contact in traditional forceps delivery and reducing the risk of injury to the baby's head.

[0017] This invention sets the thickness of the airbag at the contact point with the side wall of the third mounting groove to be thinner than other positions. When inflated, the thinner position deforms more significantly, which can more effectively push the first and second water bags out of the groove and away from each other. This can push the mucus or other impurities on the surface of the baby's head to both sides, making the cavity between the water bags free of impurities. This avoids impurities reducing the friction between the forceps and the baby's head, thereby improving the stability of the clamping.

[0018] This invention, by setting up a negative pressure component, utilizes the cooperation of the negative pressure chamber and the second piston to create negative pressure in the cavity between the first and second water bladders, thereby adsorbing the baby's head and ensuring that the forceps head surface is completely in contact with the baby's head, further improving the reliability of clamping and preventing the forceps from slipping during use.

[0019] This invention incorporates a pressure sensor installed inside the corrugated tube between the first and second water bladders. The pressure sensor detects water pressure and displays the pressure data in real time on a display screen on the forceps handle. Medical personnel can precisely adjust the clamping force of the forceps on the baby's head based on the data displayed on the screen, avoiding excessive or insufficient clamping force that could affect the safety of childbirth, thus achieving personalized and precise operation.

[0020] This invention incorporates a locking assembly, which includes a latch, a pull rope, a hook, and a feed roller. Rotating the feed roller tightens the pull rope, causing the clamping handles to move closer together, thereby adjusting the clamping distance of the clamping heads. The locking block restricts the rotation of the feed roller, fixing the clamping head position. This design is convenient and reliable, meeting the adjustment needs of different childbirth scenarios.

The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0025] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0026] The following reference Figures 1-9 This invention describes an adjustable forceps for assisting with clinical delivery in obstetrics and gynecology.

[0027] An adjustable forceps for clinical delivery assistance in obstetrics and gynecology, suitable for clinical delivery assistance, includes a forceps body comprising two cross-arranged forceps bodies 100. The two forceps bodies 100 are separately configured, and each forceps arm 120 of the two forceps bodies 100 has a connecting hole 130 in the middle. When the two connecting holes 130 are aligned, a connecting shaft 150 is inserted into the two connecting holes 130, and the two forceps bodies 100 form the forceps body. Each forceps body 100 has a forceps head 110, a forceps arm 120, and a forceps handle 140. The forceps head 110 is arc-shaped. The structure of the two clamp heads 110, with their arc-shaped design, allows the surfaces of the two clamp heads 110 that are close together to adapt to the baby's head. To ensure that the surfaces of the two clamp heads 110 can completely fit the baby's head, the invention provides a groove 200 on the surfaces of the two clamp heads 110 that are close together. A first water bladder 210 and a second water bladder 220 are disposed within the groove 200. The first water bladder 210 is located outside the second water bladder 220. An air bladder 260 is disposed between the first water bladder 210 and the second water bladder 220. After inflation, the first water bladder 210 and the second water bladder 220 are pushed outward from the groove 200. Most of the first and second water bladders extend out of the groove 200 and fit snugly against the baby's head. Because both the first and second water bladders are elastic, they fit completely against the baby's head when they contact it. Furthermore, since the air bladder 260 is located between the first and second water bladders, its inflation also pushes the first water bladder 210 and the second water bladder 220 outward. The first water sac 210 and the second water sac 220 are pushed to the sides, which causes the first water sac 210 and the second water sac 220 to move away from each other. When the first water sac 210 and the second water sac 220 move away from each other, they can push the mucus or other impurities on the surface of the baby's head to the sides, so that there is no mucus or other impurities in the cavity 460 between the first water sac 210 and the second water sac 220. This can prevent the mucus or other impurities from reducing the friction between the baby's head and the forceps head 110, and improve the stability of the forceps body in holding the baby's head.

[0028] The two clamps 100 are equipped with negative pressure components, which can create negative pressure in the cavity 460 between the first water bladder 210 and the second water bladder 220, thereby adsorbing the baby's head and ensuring that the surfaces of the two clamp heads 110 that are close to each other can completely fit the baby's head.

[0029] Specifically, such as Figure 4 , Figure 5 and Figure 9As shown, in this embodiment of the invention, the clamp handle 140 has a receiving cavity 300 inside. The receiving cavity 300 is connected to the airbag 260 through the air passage 350. A first piston 320 is slidably disposed in the receiving cavity 300. The first piston 320 can move within the receiving cavity 300, thereby squeezing the gas in the receiving cavity 300 into the airbag 260. The airbag 260 begins to inflate, thereby pushing the first water bag 210 and the second water bag 220. When the airbag 260 inflates to a certain extent, the first piston 320 stops moving, thereby preventing the gas inside the airbag 260 from returning to the receiving cavity 300. To limit the position of the first piston 320, a first limiting block 340 is slidably disposed within the receiving cavity 300. The sliding direction of the first limiting block 340 is perpendicular to the sliding direction of the first piston 320. The first limiting block 340 has an inclined surface, such as... Figure 9 As shown, there are two first limiting blocks 340, which are located on the two side walls of the receiving cavity 300. A sealing plate 330 is provided on one end of the first piston 320, and a first grip handle 310 is provided on the other end of the first piston 320. A wedge-shaped groove is formed between the sealing plate 330 and the first piston 320. When the medical staff pushes the first grip handle 310 to move the piston in the receiving cavity 300, the air in the receiving cavity 300 is squeezed into the airbag 260 by the sealing plate 330. When the first piston 320 passes the two first limiting blocks 340, the inclined surfaces of the two first limiting blocks 340 are located in the wedge-shaped groove. The two first limiting blocks 340 restrict the first piston 320 and prevent the first piston 320 from resetting.

[0030] It should be noted that the two first limiting blocks 340 in this embodiment are provided with reset springs. The reset springs can push the first limiting blocks 340 to move toward the inside of the receiving cavity 300 or make the first limiting blocks 340 tend to move toward the inside of the receiving cavity 300. When the first piston 320 passes the two first limiting blocks 340, the two first limiting blocks 340 move toward the inside of the receiving cavity 300 under the action of the reset springs, thereby restricting the reset of the first piston 320.

[0031] Specifically, such as Figure 5 and Figure 8As shown, the negative pressure assembly in this embodiment includes a negative pressure chamber 400 and a second piston 420. The negative pressure chamber 400 is located inside the clamp handle 140. The second piston 420 is slidably sealed within the negative pressure chamber 400. An annular cavity 450 is formed inside the clamp head 110, communicating with the negative pressure chamber 400 and the cavity 460 between the first water bladder 210 and the second water bladder 220. Initially, the second piston 420 is located at the innermost part of the negative pressure chamber 400. When the second piston 420 moves outward within the negative pressure chamber 400, the air pressure between the second piston 420 and the annular cavity 450 decreases. The annular cavity 450 communicates with the cavity 460 between the first water bladder 210 and the second water bladder 220, thus creating a negative pressure in the cavity 460. This allows the first and second water bladders to adhere to the baby's head. To prevent the second piston 420 from resetting, as shown... Figure 8 As shown, a second limiting block 440 is slidably disposed in the negative pressure chamber 400. The sliding direction of the second limiting block 440 is perpendicular to the sliding direction of the second piston 420. There are two second limiting blocks 440, which are located on the side wall of the negative pressure chamber 400. The end faces of the two second limiting blocks 440 that are close to each other are also inclined surfaces. When the second piston 420 moves from the innermost part of the negative pressure chamber 400 to the outermost part, the second piston 420 passes through the inclined surfaces of the two second limiting blocks 440 and crosses the second limiting blocks 440. The second limiting blocks 440 prevent the second piston 420 from resetting.

[0032] It should be noted that in this embodiment, a return spring is also provided on the second limiting block 440. The return spring is used to push the second limiting block 440 to move inward in the negative pressure chamber 400 or to make the second limiting block 440 tend to move inward in the negative pressure chamber 400. A sealing block 430 is fixedly provided on one end of the second piston 420, and a second grip handle 410 is fixedly provided on the other end of the second piston 420. A wedge-shaped surface is provided on the outer periphery of the second piston 420 away from the sealing block 430. When the medical staff pulls the second grip handle 410 to pull the second piston 420 outward from the negative pressure chamber 400, the sealing block 430 and the annular cavity 45... The air pressure gradually decreases between 0 and 0. When the wedge-shaped surface on the outer periphery of the second piston 420 passes the two second limiting blocks 440, it can push the two second limiting blocks 440 away from each other, thereby compressing the return spring. When the wedge-shaped surface on the outer periphery of the second piston 420 passes the two second limiting blocks 440, the medical staff stops pulling the second grip handle 410. After the return spring on the second limiting block 440 is reset, the second limiting block 440 obstructs the second piston 420 from resetting, thereby preventing the air pressure inside the annular cavity 450 and the cavity 460 between the first water bladder 210 and the second water bladder 220 from increasing, so that the first air bladder 260 and the second air bladder 260 can be attached to the baby's head.

[0033] Specifically, in the embodiments of the present invention, a connecting hole (not shown in the figure) is provided at the bottom of the groove 200. The connecting hole is used to connect the annular cavity 450 with the groove 200. The cavity 460 between the first water bladder 210 and the second water bladder 220 in the groove 200 is connected to the groove 200. That is to say, by setting the connecting hole, the annular cavity 450 can be connected with the cavity 460 between the first water bladder 210 and the second water bladder 220, so that when the second piston 420 in the negative pressure chamber 400 is pumped out, the cavity 460 between the first water bladder 210 and the second water bladder 220 can also be in a negative pressure state, thereby adsorbing the baby's head.

[0034] In a further embodiment, such as Figure 6 and Figure 7 As shown, to allow the first water bladder 210 and the second water bladder 220 to be installed in the groove 200, a first mounting groove 230 and a second mounting groove 240 are provided at the bottom of the groove 200. A first mounting plate 211 is fixedly installed on the side wall of the first water bladder 210. The first mounting plate 211 is interference-fitted with the first mounting groove 230, so that the first mounting plate 211 is engaged in the first mounting groove 230. Similarly, a second mounting plate 221 is fixedly installed on the side wall of the second water bladder 220. The second mounting plate 221 is interference-fitted with the second mounting groove 240, so that the second mounting plate 221 is engaged in the second mounting groove 240. A third mounting groove 250 is provided between the first mounting groove 230 and the second mounting groove 240. The third mounting groove 250 is used to install an airbag 260. When the airbag 260 is inflated in the third mounting groove 250, part of it will extend out of the third mounting groove 250, so that the airbag 260 can squeeze the first water bladder 210 and the second water bladder 220 out of the groove 200.

[0035] It should be noted that an inclined plate is provided between the side wall and the bottom of the groove 200. The inclined plate can block the space between the side wall and the bottom of the groove 200, so that when the airbag 260 pushes the first water bag 210 and the second water bag 220, the first water bag 210 and the second water bag 220 can extend more out of the groove 200 under the action of the inclined plate, thereby improving the degree of fit between the first water bag 210 and the second water bag 220 and the baby's head.

[0036] In a further embodiment, such as Figure 7As shown, to ensure that the first water bladder 210 and the second water bladder 220 can be pushed to both sides when the airbag 260 is inflated, the thickness of the airbag 260 is different at different positions in this embodiment. Specifically, the airbag 260 is thinner at the position where it contacts the side wall of the third mounting groove 250, while it is thicker at other positions. This results in less deformation at the thicker positions of the airbag 260 when it is inflated, while greater deformation at the thinner positions. The thicker parts of the airbag 260 extend out of the third mounting groove 250 and move towards the first water bladder 210 and the second water bladder 220, thereby pushing the first water bladder 210 and the second water bladder 220.

[0037] Specifically, in this embodiment, the first water bladder 210 and the second water bladder 220 are connected by a corrugated tube (not shown in the figure). One end of the corrugated tube is connected to the first water bladder 210, and the other end is connected to the second water bladder 220. The first water bladder 210 and the second water bladder 220 are filled with liquid, and a pressure sensor (not shown in the figure) is installed inside the corrugated tube. The pressure sensor can detect the liquid pressure in the corrugated tube. Since the first water bladder 210 and the second water bladder 220 are connected by the corrugated tube, the liquid pressure inside the first water bladder 210 and the second water bladder 220 is the same as the liquid pressure in the corrugated tube. A display screen 600 is installed on the clamp handle 140. The pressure sensor is electrically connected to the display screen 600, so the data detected by the pressure sensor can be displayed on the display screen 600. Medical personnel can know the pressure of the first water bladder 210 and the second water bladder 220 on the baby's head by the liquid pressure displayed on the display screen 600.

[0038] In a further embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the locking assembly of the present invention includes a latch 500, a pull cord 520, a hook 530, and a feed roller 510. The latch 500 and the feed roller 510 are respectively mounted on two clamp handles 140. The feed roller 510 is rotatably mounted on the clamp handles 140. One end of the pull cord 520 is wrapped around the outer periphery of the feed roller 510, and the other end of the pull cord 520 is connected to the hook 530. The hook 530 can be hooked on the latch 500. When the medical staff rotates the feed roller 510 to tighten the pull cord 520, the hook 530 and the latch 500 can pull the two clamp handles 140 closer to each other, so that the two clamp heads 110 can also be brought closer to each other to clamp the baby's head.

[0039] Specifically, to fix the positions of the two clamp heads 110, that is, to fix the positions of the two clamp handles 140, a locking block 540 is also provided on the clamp handles 140. The locking block 540 is located on the outer periphery of the feed roller 510. In this embodiment, the outer periphery of the feed roller 510 has teeth, and the locking block 540 is also provided with teeth. Furthermore, the locking block 540 can move radially along the feed roller 510, thereby restricting the rotation of the feed roller 510 or releasing the restriction on the feed roller 510.

[0040] It should be noted that the pay-off roller 510 in this invention is equipped with a torsion spring (not shown in the figure). The torsion spring enables the pay-off roller 510 to rotate to tighten the pull rope 520. The pull rope 520 pulls the locking buckle 500, causing the two clamp handles 140 to move closer to each other. This allows the first water bladder 210 and the second water bladder 220 on the two clamp heads 110 to initially fit against the baby's head. Subsequently, the medical personnel push the first piston 320 into the receiving cavity 300 and restrict it with the two first limiting blocks 340. At this time, the air bladder 260 is filled with gas. 260 pushes the first water bladder 210 and the second water bladder 220 away from each other. The first water bladder 210 and the second water bladder 220 scrape away the mucus or other substances on the surface of the contact part of the baby's head. The medical staff pulls the second piston 420 in the negative pressure chamber 400, so that the cavity 460 between the first water bladder 210 and the second water bladder 220 forms a negative pressure, thereby making the first water bladder 210 and the second water bladder 220 completely fit against the baby's head, increasing the contact area between the two forceps heads 110 and the baby's head, and improving the clamping effect of the forceps body.

[0041] It is understandable that the pressure data on the display screen 600 will change when the medical staff adjusts the position of the two forceps 140. Adjusting the position of the two forceps 140 changes the pressure of the first water bladder 210 and the second water bladder 220 on the infant's head. When the two forceps 140 are brought closer together, the two forceps 110 are brought closer together, thus squeezing the first water bladder 210 and the second water bladder 220. The liquid pressure inside the bellows connected to the first water bladder 210 and the second water bladder 220 will change. The pressure sensor inside the bellows can sense the pressure change and feed it back to the display screen 600. When the medical staff moves the second piston 420 within the negative pressure chamber 400, a negative pressure is formed inside the cavity 460 between the first water bladder 210 and the second water bladder 220. Therefore, when the first water bladder 210 and the second water bladder 220 are subjected to negative pressure, the internal liquid will also experience a pressure change. The medical staff is then set to... When the second piston 420 moves to the position restricted by the two second limit blocks 440, the force exerted on the first water bladder 210 and the second water bladder 220 is 5N. For example, if a force of 10N is required to clamp the baby's head, then the liquid pressure inside the first water bladder 210 and the second water bladder 220 only needs to be 5N to meet the requirement, which is the data displayed on the display screen 600 is 5N. The medical staff rotates the feeding roller 510, so that the pull rope 520 on the feeding roller 510 pulls the two clamp handles 140 closer to each other through the hook 530, and the two clamp heads 110 come closer to each other to squeeze the first water bladder 210 and the second water bladder 220. When the data on the display screen 600 is 5N, the rotation of the feeding roller 510 is stopped, and the locking block 540 is pushed close to the feeding roller 510 to restrict the rotation of the feeding roller 510. Finally, the second piston 420 is moved to the position restricted by the two second limit blocks 440. At this time, the clamping force of the two clamp heads 110 on the baby's head is exactly 10N.

[0042] The specific usage process of the adjustable forceps for assisting obstetric and gynecological delivery provided by the present invention will be described in conjunction with the above embodiments: During childbirth, in cases of cephalic presentation dystocia or fetal asphyxia due to prolonged labor, medical personnel insert two forceps 100 into the birth canal sequentially, bringing the forceps heads 110 of the two forceps 100 into contact with the baby's head. The two forceps 100 are then connected via a connecting shaft 150. The feed roller 510 on the forceps handle 140 is then rotated. The medical personnel pull the hook 530, causing the pull rope 520 on the hook 530 to rotate the feed roller 510. The feed roller 510 overcomes the force of the torsion spring, and the medical personnel hook the hook 530 onto the outer periphery of the locking buckle 500 on the other forceps handle 140. The feed roller 510 then rotates against the torsion spring (Figure...). Under the action of (not shown), the pull cord 520 is tightened. The pull cord 520, through the hook 530 and the lock 500, pulls the two clamp handles 140 closer together. When the two clamp handles 140 are closer together, they can drive the two clamp heads 110 to be closer together. The first water bladder 210 and the second water bladder 220 on the two clamp heads 110 retract into the groove 200. Then, the medical staff holds the first grip handle 310 and pushes the first piston 320 to move within the receiving cavity 300. The air bladder 260 in the third mounting groove 250 is inflated, thereby pushing the first water bladder 210 and the second water bladder 220 to move outward from the groove 200 and contact the baby's head. The specific state is as follows. Figure 7 As shown, the airbag 260 pushes the first water bladder 210 and the second water bladder 220 away from each other, so that the first airbag 260 and the second airbag 260 can scrape away the mucus or other substances on the baby's head, so that the cavity 460 between the first water bladder 210 and the second water bladder 220 is free of mucus or other substances.

[0043] Medical personnel push the first piston 320 within the receiving cavity 300 until it stops moving, restrained by the two first limiting blocks 340. They then adjust the clamping force of the two clamp heads 110 on the infant's head. The medical personnel rotate the feed roller 510, which tightens the pull rope 520, reducing the distance between the two clamp handles 140. At this point, the force exerted by the two clamp heads 110 on the infant's head gradually increases, and the liquid pressure inside the first and second water bladders 210 and 220 gradually increases, resulting in an increase in the pressure data displayed on the screen 600. Based on experience, the medical personnel adjust the clamping force of the two clamp heads 110 on the infant's head. After adjusting to a suitable force, they move the locking block 540 closer to the feed roller 510, which then restrains the feed roller 510. The distance between the two forceps heads 110 is fixed. Finally, the medical staff holds the second grip handle 410 and pulls the second piston 420 to move it within the negative pressure chamber 400. Specifically, the second piston 420 is pulled away from the negative pressure chamber 400, thus creating a negative pressure state inside the negative pressure chamber 400. The negative pressure chamber 400 is connected to the annular chamber 450, and the annular chamber 450 is connected to the cavity 460 between the first water bladder 210 and the second water bladder 220 through a connecting hole. Therefore, the cavity 460 between the first water bladder 210 and the second water bladder 220 is also in a negative pressure state, allowing the first water bladder 210 and the second water bladder 220 to fit tightly against the baby's head. The first water bladder 210 and the second water bladder 220 can fit completely against the baby's head, avoiding excessive local pressure from the forceps.

[0044] After the medical staff adjusted the clamping forceps, they held the handles and pulled the forceps body. The forceps pulled on the baby's head, helping the baby to be delivered slowly through the birth canal.
