[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The adjustable gynecological and obstetric forceps disclosed in the present invention are mainly used in scenarios where the existing gynecological and obstetric forceps cannot be adjusted to control the clamping force.

[0024] Reference Figures 1-8 , an adjustable gynecological and obstetric forceps, comprising two symmetrical forceps handles 1;

[0025] There are two clamp arms 2, which are staggered with each other, and the sides of the two clamp arms 2 close to the clamp handle 1 are respectively connected to the outside of the clamp handle 1 by bolts;

[0026] There are two fixing plates 3, which are symmetrical to each other and are both located outside the clamp arm 2 on the same side;

[0027] There are two pliers 4, which are symmetrical to each other. The outer parts of the pliers 4 are rotatably connected to the outer parts of the fixed plate 3 on the same side through bearings, and the opposite sides of the two pliers 4 are connected to multiple micro pressure sensors 5 by bolts;

[0028] The pressure adjustment module 6 includes an inclined panel 604, which is connected to the side of the forceps 4 on the same side by bolts, and an extrusion block 605 is provided on the outside of the inclined panel 604, and the side of the inclined panel 604 opposite to the extrusion block 605 is parallel, and the two opposite sides of the two fixing plates 3 are connected to the buzzer alarm 602 by bolts. The pressure adjustment module 6 is used to adjust the angle of the forceps 4 when the doctor uses too much force when using the forceps, thereby reducing the pressure of the forceps 4 on the baby's head and protecting the baby's head; the pressure sensor 5 can accurately sense the pressure and better protect the fetus.

[0029] Specifically, when the doctor uses forceps to assist in delivery, the forceps blades 4 are clamped on the baby's head. When the doctor presses the forceps handles 1 to make the forceps arms 2 drive the forceps blades 4 to apply pressure to the baby's head, the micro pressure sensor 5 will detect the pressure. When the pressure is too high, the micro pressure sensor 5 will control the buzzer alarm 602 to sound an alarm, so that the doctor can use the pressure adjustment module 6 to adjust the angle of the forceps blades 4, so that when the doctor brings the two forceps handles 1 together, the forceps blades 4 can just clamp the baby's head with the optimal pressure. When the shape of the baby's head is not compatible with the forceps blades 4, the quick replacement module 7 is used to disassemble the original forceps blades 4 and re-fix the forceps blades 4 of the adapted shape. The device uses the pressure adjustment module 6 to adjust the retraction angle of the forceps blades 4 with the help of the prompt of the micro pressure sensor 5 when the doctor uses the forceps too much force. This reduces the pressure of the forceps blades 4 on the baby's head, protects the baby's head, effectively reduces safety risks, and protects the safety of the baby.

[0030] In the present invention, the pliers blade 4 can be quickly replaced through the detachable and washable structure. The quick-replacement module 7 can ensure the stability of the pliers blade 4 and will not cause the pliers blade 4 to loosen during use and cause damage to the fetus or birth canal. The pliers blade 4 is made of wear-resistant material to increase wear resistance and provide service life.

[0031] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 6In a preferred embodiment, the outsides of the two fixing plates 3 are connected with elastic springs 601 by bolts, and the ends of the elastic springs 601 away from the fixing plates 3 are connected with the outsides of the pliers 4 on the same side by bolts. The fixing plates 3 are provided with mounting grooves 603, and the inner walls of the mounting grooves 603 are provided with two symmetrical narrow grooves. The outsides of the extrusion blocks 605 are slidably connected with the inner walls of the narrow grooves, and the outsides of the inclined plates 604 are slidably connected with the inner walls of the mounting grooves 603 on the same side. The inclined plates 604 are connected with the outsides of the pliers 4 on the same side by bolts, and the side of the extrusion blocks 605 away from the pliers 4 is connected with a spring 601 by bolts. 06, the other end of the spring 606 is connected to the inner wall of the mounting groove 603 by bolts, and the inclined plate 604 is provided with a slide groove 624, and the slide groove 624 is slidably connected to the limit member 625, and the limit member 625 is connected to the side opposite to the extrusion block 605 on the same side by bolts. The opposite side of the two extrusion blocks 605 is fixedly connected with an inclined member 626, and the outside of the limit member 625 is slidably connected to the outside of the inclined member 626; the outside of the two fixed plates 3 is provided with two symmetrical incisions, and the inner walls of the incisions are connected with a rack 608 by bolts, and the opposite side of the two extrusion blocks 605 is connected with two by bolts. Symmetrical wing plates 607 are provided with rectangular openings on the wing plates 607, and the rectangular openings are slidably connected with a clamping block 612, and the clamping block 612 is clamped with the rack 608 on the same side, and the outside of the clamping block 612 is connected to a thin rod by bolts, and the outside of the thin rod is slidably connected to a stabilizing frame 613; multiple stabilizing frames 613 are connected to the side opposite to the wing plate 607 on the same side by bolts, and the outside of the thin rod is surrounded by a spring 2 614, one end of the spring 2 614 is connected to the outside of the stabilizing frame 613 on the same side by bolts, and the other end is connected to the outside of the wing plate 607 on the same side by bolts, and the outside of the extrusion block 605 is connected by bolts. A thin rope 611 is connected; the outside of the thin rope 611 is slidably connected to a round rod 610, and the top and bottom of the round rod 610 are connected to the same pulling frame 609 by bolts. The pulling frame 609 is connected to the side opposite to the fixed plate 3 on the same side by bolts, and the two fixed plates 3 are connected to the connecting seat 615 on the opposite sides by bolts. The connecting seat 615 is rotatably connected to the rotating shaft through a bearing, and the outside of the rotating shaft is connected to the winding roller 616 by bolts, and the end of the thin rope 611 away from the extrusion block 605 is connected to the outside of the winding roller 616 on the same side by bolts. A quick replacement module 7 is provided on both fixed plates 3;The upper sides of both rotating shafts are bolted to knobs 617, which are slidably connected to the side of knobs 617 opposite the connecting base 615. The upper side of the connecting base 615 is bolted to a support bracket 618, which is bolted to a circular shaft 619 on its upper side. A lower inclined block 621 is bolted to the exterior of each circular shaft 619, which is slidably connected to an upper inclined block 620. The upper inclined block 620 and the lower inclined block 621 are symmetrical. An isolation frame 622 is slidably connected to the exterior of each circular shaft 619. Isolation frames 622 are located outside knobs 617, and springs 623 are bolted to the exterior of each isolation frame 622. The other end of each spring 623 is bolted to the upper side of the supporting bracket 618 on the same side.

[0032] Specifically, when the micro pressure sensor 5 detects that the clamping force of the pliers 4 is too large, the buzzer alarm 602 sounds an alarm, and the upper inclined surface block 620 is rotated to 180 degrees, so that the upper inclined surface block 620 is parallel to the inclined surface on the lower inclined surface block 621. Under the pull of the spring 3 623, the two inclined surfaces fit together, so that the isolation frame 622 slides down on the circular shaft 619, exposing the knob 617. The knob 617 is rotated to drive the winding roller 616 to rotate, thereby reeling in the thin rope 611, so that the thin rope 611 pulls the extrusion block 605 to move toward the pliers 4. The limiter 625 on the moving extrusion block 605 slides on the slide groove 624, so that the distance between the extrusion block 605 and the inclined plate 604 is gradually reduced. Until it contacts the inclined surface of the inclined plate 604, so that the inclined plate 604 drives the pliers 4 to rotate outward on the fixed plate 3, and the block 612 on the wing plate 607 continuously overcomes the elastic force of the spring 2 614 during the movement of the squeezing block 605, and moves with the squeezing block 605 on the rack 608. When the micro pressure sensor 5 no longer alarms, stop turning the knob 617. At this time, the block 612 is engaged and locked with the rack 608, and the upper inclined surface block 620 is rotated in the opposite direction to one hundred and eighty degrees, so that the inclined surface on the lower inclined surface block 621 lifts the upper inclined surface block 620 until the upper inclined surface block 620 and the lower inclined surface block 621 are symmetrical with each other. The lifted upper inclined surface block 620 drives the isolation frame 622 to rise, so that the isolation frame 622 isolates the knob 617.

[0033] In a specific application scenario, the pressure adjustment module 6 is mainly suitable for the pressure adjustment link in the pressure adjustment process, that is, the pressure adjustment module 6 uses the micro pressure sensor 5 and the buzzer alarm 602 to enable the device to detect and prompt the clamping force when the doctor uses forceps to clamp the baby's head, and prevent excessive pressure. The inclined panel 604, the limiter 625, the tilting member 626 and the squeezing block 605 can be used to quickly and conveniently control the rotation angle of the forceps 4, reduce the complexity of the operation, enable the doctor to respond in time, and reduce the risk of injury to the baby. The upper inclined block 620, the lower inclined block 621 and the isolation frame 622 can effectively isolate the knob 617, so that the knob 617 can be isolated from the external environment before and after the operation, avoiding accidental touch.

[0034] Reference Figure 7 and Figure 8 In a preferred embodiment, the two quick-change modules 7 each include a latch 709, and an annular groove 710 is provided on the two latches 709. The latch 709 is connected to the fixed plate 3 on one side by a bolt. A groove is provided on the clamp arm 2, and an insertion seat 703 is connected to the groove by a bolt. The inner wall of the insertion seat 703 is plugged into the outer part of the latch 709 on the same side, and the insertion seat 703 is provided with three circumferentially equidistant grooves 704; a locking rod 705 is slidably connected to the multiple grooves 704, and the side of the locking rod 705 away from the insertion seat 703 is connected to a short shaft by a bolt, and the outer part of the latch 709 is slidably connected to the rotating frame 706, and the rotating frame 706 is slidably connected to the side opposite to the insertion seat 703 on the same side. The two rotating frames 706 are rotatably connected through bearings; three curved grooves 708 with equal distances around the circumference are provided on each of the two rotating frames 706, and the inner walls of the curved grooves 708 are slidably connected to the outside of the short shaft on the same side, and the end of the locking rod 705 close to the pin 709 is clamped with the inner wall of the annular groove 710, and the outside of the rotating frame 706 is connected to the driving rod 707 by bolts; the inner walls of the two rotating frames 706 are connected to the coil spring 711 by bolts, and the end of the coil spring 711 away from the rotating frame 706 is connected to the outside of the insertion seat 703 on the same side by bolts, and the outside of the two clamp arms 2 are provided with two symmetrical insertion grooves 701, and a limit pin 702 is provided in the insertion groove 701, and the limit pin 702 is connected to the side opposite to the fixed plate 3 on the same side by bolts.

[0035] During actual use, when cleaning the groove and the annular groove 710 , the blood hidden inside can be cleaned well by ultrasonic vibration without increasing maintenance costs.

[0036] Specifically, when the shape of the pliers 4 is not compatible with the baby's head or fetal position, the lever 707 is rotated to make the rotating frame 706 rotate synchronously to overcome the torsion of the coil spring 711. The curved groove 708 on the rotating frame 706 gently pushes the short shaft, causing the locking rod 705 to slide outward on the cutting groove 704, thereby releasing the locking rod 705 from the annular groove 710, and lightly pressing the fixing plate 3 away from one end of the pliers arm 2, so that the fixing plate 3 rotates with the limit pin 702 in the insertion groove 701 as the fulcrum, thereby pulling the pin 709 out of the insertion seat 703, removing the pliers 4 from the pliers arm 2, and reversing the above steps to install the new pliers 4 that adapts to the shape of the baby's head on the pliers arm 2.

[0037] In specific application scenarios, the quick-change module 7 is mainly suitable for the quick-change link in the quick-change process, that is, the quick-change module 7 uses the limit pin 702, the locking rod 705 and the curved groove 708 to complete the disassembly and installation of the forceps 4. While ensuring the stability of the connection, it greatly reduces the time for disassembly and reinstallation. Moreover, the detachable forceps 4 also ensures that the forceps can be synchronously changed and adapted according to the fetal position and head shape of the baby, which greatly improves the applicability of the forceps and improves the midwifery effect.

[0038] Working principle: When the doctor uses forceps to assist in delivery, the blades 4 are clamped on the baby's head. When the doctor presses the forceps handle 1 to make the forceps arm 2 drive the blades 4 to apply pressure to the baby's head, when the micro pressure sensor 5 detects that the clamping force of the blades 4 is too strong, the buzzer alarm 602 sounds an alarm, and the upper inclined surface block 620 is rotated to 180 degrees, so that the upper inclined surface block 620 and the inclined surface on the lower inclined surface block 621 are parallel. Under the pull of spring 3 623, the two inclined surfaces fit together, so that the isolation frame 622 slides down on the circular shaft 619, exposing the knob 617. Turn the knob 6 17, the knob 617 drives the winding roller 616 to rotate, thereby reeling in the thin rope 611, causing the thin rope 611 to pull the extrusion block 605 to move in the direction of the pliers 4, and the limiter 625 on the moving extrusion block 605 slides on the slide groove 624, causing the distance between the extrusion block 605 and the inclined plate 604 to gradually decrease until it contacts the inclined surface of the inclined plate 604, thereby causing the inclined plate 604 to drive the pliers 4 to rotate outward on the fixed plate 3, and the block 612 on the wing plate 607 continuously overcomes the elastic force of the spring 2 614 during the movement of the extrusion block 605, and is engaged with the rack 608. As the squeezing block 605 moves, when the micro pressure sensor 5 no longer alarms, stop turning the knob 617. At this time, the block 612 is locked with the rack 608, and the upper inclined block 620 is rotated in the opposite direction to 180 degrees, so that the inclined surface on the lower inclined block 621 lifts the upper inclined block 620 until the upper inclined block 620 and the lower inclined block 621 are symmetrical with each other. The raised upper inclined block 620 drives the isolation frame 622 to rise, so that the isolation frame 622 isolates the knob 617. When the shape of the forceps 4 does not match the baby's head or fetal position, turn the lever 707 to rotate The frame 706 rotates synchronously to overcome the torsion of the coil spring 711, and the curved groove 708 on the rotating frame 706 gently pushes the short shaft, causing the locking rod 705 to slide outward on the cutting groove 704, thereby releasing the locking rod 705 from the annular groove 710, and lightly pressing the fixing plate 3 away from one end of the clamp arm 2, so that the fixing plate 3 rotates with the limit pin 702 in the insertion groove 701 as the fulcrum, thereby pulling the pin 709 out of the insertion seat 703, removing the pliers 4 from the clamp arm 2, and reversing the above steps to install the new pliers 4 that adapts to the shape of the baby's head on the clamp arm 2.
