DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0037] like Figure 1-9 As shown: an adjustable obstetrics and gynecology midwife, including a fixed arm 1, a clamping part 2, a transmission part 3 and a controller 4, the fixed arm 1 can be fixedly installed on the arm of a medical staff; the clamping part 2 includes a plurality of clamping claws, a fine-adjustment clamping block 25 arranged on the clamping claws and a head support 23 located in the middle of the clamping part 2, and a silicone gasket is arranged on the fine-adjustment clamping block 25; the two ends of the transmission part 3 are fixedly connected to the fixed arm 1 and the clamping part 2 respectively, and drive the clamping part 2 to rotate and control the opening and closing of the clamping part 2; the controller 4 is installed outside the transmission part 3 and can be used to control the device startup, charging and data collection and recording.

[0038] In this embodiment, the device is mainly composed of four parts, including a fixed arm 1, a clamping part 2, a transmission part 3 and a controller 4. The following are the specific functions and features of each part.

[0039] 1. Fixed arm 1: As the main support for medical staff to operate the midwife, it can be stably fixed on the arm of the medical staff, making the operation process more convenient and stable, and it is not easy to fall off when used by medical staff, which is convenient for exerting force and adjusting the angle and direction.

[0040] 2. Clamping part 2: This is the key part of the midwife, responsible for clamping the baby's head. The clamping part 2 is composed of multiple jaws, which can be adjusted according to the physical condition of the pregnant woman and the needs of delivery. In addition, the jaws are provided with a fine-tuning clamp block 25, which can be used to accurately control the degree of opening of the jaws through fine-tuning. In order to improve comfort, a silicone gasket is provided on the fine-tuning clamp block 25 to reduce stimulation to pregnant women. At the same time, the entire outside of the jaws is wrapped with a soft rubber jacket, which can reduce the friction damage to the birth canal when the jaws enter the body, and on the other hand, it also protects the equipment. When in use, the jaws enter the birth canal first, and after finding the correct position, the jaws are installed and fixed in sequence, and then careful traction begins.

[0041] 3. Transmission part 3: This part connects the fixed arm 1 and the clamping part 2, and is responsible for driving the clamping part 2 to rotate and open and close. Through the operation of the transmission part 3, medical staff can control the delivery process more accurately.

[0042] 4. Controller 4: Controller 4 is located outside the transmission part 3, which is convenient for medical staff to operate. It can be used to start the device, charge the internal power supply, and display various data, such as the squeezing force of the clamp on the baby's head. Through controller 4, medical staff can understand various data during delivery in real time, providing safer and more efficient medical services for pregnant women.

[0043] The adjustable obstetrics and gynecology midwife in this embodiment is intended to provide a convenient, efficient and safe delivery tool for medical staff. Through the synergistic effect of various parts, the device can meet the delivery needs of different pregnant women and improve the smooth progress of the delivery process. In addition, the device also has the advantages of easy operation and easy carrying, and is expected to be widely used in the field of obstetrics and gynecology.

[0044] like Figure 2 As shown: the fixed arm 1 includes a fixed portion 11, which is provided with a binding rope or a binding strap with letter stickers. The fixed arm 1 also includes a gripping portion 12, which is located at the front end of the fixed portion 11, and the front end of the fixed portion 11 is provided with a plurality of annular anti-slip grooves or anti-slip protrusions.

[0045] In this embodiment, the fixed arm 1 is mainly composed of two parts: a fixing part 11 and a holding part 12. The fixing part 11 serves as the basis of the entire fixed arm 1, and its main function is to fix and support. In order to achieve this function, a binding rope or a strap with letter stickers is provided. This design makes the fixing part 11 more stable and less likely to slide during use, thereby improving the safety of use. On the other hand, the holding part 12 of the fixed arm 1 is the part that is directly operated by the user. It is located at the front end of the fixing part 11, which is convenient for the user to hold and operate. In order to improve the comfort and stability of holding, a number of annular anti-slip grooves or anti-slip protrusions are designed at the front end of the holding part 11. This design not only makes the grip more comfortable, but also prevents the product from falling off due to unstable grip during use, further improving the safety of product use.

[0046] like Figure 2-8 As shown: the transmission part 3 includes a sleeve 34, a rotating shaft 31 arranged in the sleeve 34, a motor 35 located on one side of the sleeve 34 to drive the rotating shaft 31 to rotate, and a protective shell 32 located outside the sleeve 34, and the controller 4 is installed on the protective shell 32. The clamping part 2 also includes a clamping seat 24, the clamping seat 24 is fixed at the end of the rotating shaft 31, and there are three clamping jaws evenly installed on the clamping seat 24. The clamping jaws include a primary clamping jaw 21 and a secondary clamping jaw 22 installed at the end of the primary clamping jaw 21, the primary clamping jaw 21 is hinged to the clamping seat 24, the secondary clamping jaw 22 is hinged to the primary clamping jaw 21, and a micro-adjusting cylinder 26 is arranged between the primary clamping jaw 21 and the clamping seat 24 and between the primary clamping jaw 21 and the secondary clamping jaw 22. There are a plurality of fine-tuning clamping blocks 25 which are evenly arranged inside the primary clamping jaw 21 and the secondary clamping jaw 22 , and the volume of the fine-tuning clamping block 25 gradually decreases from the initial end of the primary clamping jaw 21 to the final end of the secondary clamping jaw 22 .

[0047] In this embodiment, the transmission part 3 is mainly composed of four parts, namely, a sleeve 34, a rotating shaft 31, a motor 35 and a protective shell 32. As the core component of the transmission part, the sleeve 34 is responsible for the installation and fixing of the rotating shaft 31. The rotating shaft 31 is the power output part of the entire transmission system. It is located inside the sleeve 34 and driven by the motor 35 to drive the rotation of the rotating shaft 31. The protective shell 32 is located on the outside of the sleeve 34, mainly to protect the internal components and prevent accidental damage. In addition, the controller 4 is also installed on the protective shell 32, which is responsible for controlling the operation of the entire transmission system. In this embodiment, we adopt this structural design to ensure the stability and safety of the transmission system. The clamping part 2 is mainly composed of a clamping seat 24 and a clamping claw. The clamping seat 24 is fixed to the end of the rotating shaft 31 to support and stabilize the clamping claw. There are three clamps in total, which are evenly installed on the clamp seat 24. This design ensures the stability of the clamps during operation. When using it, first extend the clamps into the birth canal, find the position on the baby's head, and then fix them to the clamp seat in turn, and then fine-tune the angle of the clamps through the controller. The clamps include a primary clamp 21 and a secondary clamp 22. The primary clamp 21 is hinged to the clamp seat 24, and the secondary clamp 22 is hinged to the primary clamp 21. This hinged design allows the clamps to have better flexibility during operation. At the same time, micro-adjustment cylinders 26 are provided between the primary clamp 21 and the clamp seat 24 and between the primary clamp 21 and the secondary clamp 22. This design enhances the precise adjustment ability of the clamps. There are several fine-tuning clamps 25, which are evenly arranged on the inner side of the primary clamp 21 and the secondary clamp 22. In particular, the volume of the fine-tuning clamp 25 gradually decreases from the initial end of the primary clamp 21 to the end of the secondary clamp 22. This design makes the clamp more precise during fine-tuning and can meet the needs of various delicate operations.

[0048] In short, in this embodiment, we make the transmission part 3 and the clamping part 2 form an efficient, stable and safe whole through reasonable structural design and fine process manufacturing. This design not only improves the operating performance of the equipment, but also greatly reduces the failure rate and maintenance cost, bringing a better user experience to the user. In addition, this embodiment is only an example, and in actual application, it can also be appropriately adjusted according to demand to achieve better performance, for example, the clamping jaws can be divided more carefully, primary clamping jaws, secondary clamping jaws, tertiary clamping jaws and more, so as to facilitate more fine adjustment of the angle to reduce the squeeze on the baby's head.

[0049] like Fig. 9As shown: the fine-tuning clamp 25 is a special-shaped bench vise, and the fine-tuning clamp 25 includes a displacement module, which includes a primary displacement block. One side of the primary displacement block is a semicircular arc structure, and a secondary displacement block is arranged on the other side of the arc edge of the primary displacement block. The two secondary displacement blocks are symmetrically arranged along the axis of the primary displacement block. The secondary displacement block is also arranged in conjunction with a tertiary displacement block. The secondary displacement block and the tertiary displacement block are similar in structure to the primary displacement block, and their sizes decrease step by step. Every two tertiary displacement blocks are symmetrically arranged along the axis of a secondary displacement block, and a silicone gasket is arranged on the contact side of the tertiary displacement block.

[0050] In this embodiment, Fig. 9 As shown, the fine-adjustment clamp 25 adopts the design of a special-shaped bench vise, which is a prior art and has excellent performance and function. The core part of the special-shaped bench vise fine-adjustment clamp 25 is the displacement module, which is responsible for achieving precise adjustment of the pliers. The displacement module is composed of multiple levels of displacement blocks, which cooperate with each other to achieve precise adjustment of the pliers under different working conditions.

[0051] The primary displacement block is the basic part of the displacement module, and one side of it presents a semicircular arc structure. This design enables the primary displacement block to perfectly cooperate with the secondary displacement block to achieve fine-tuning of the pliers. At the same time, the other side of the arc edge of the primary displacement block is specially equipped with a secondary displacement block. The two secondary displacement blocks are symmetrically arranged along the axis of the primary displacement block to ensure the stability of the pliers during the adjustment process.

[0052] In addition, the secondary displacement block is also equipped with a tertiary displacement block. The tertiary displacement block is similar in structure to the primary displacement block, but is smaller in size, which enables the size of the pliers to be adjusted in a step-by-step manner. It is worth mentioning that every two tertiary displacement blocks are symmetrically arranged along the axis of a secondary displacement block. This design not only ensures the accuracy of the pliers adjustment, but also improves the convenience during use.

[0053] A silicone gasket is set on the contact side of the three-stage displacement block. This design is intended to increase friction and protect the fetus.

[0054] In this embodiment, the design of the special-shaped bench vise fine-tuning clamp 25 fully reflects humanization and intelligence. Multiple levels of displacement blocks cooperate with each other, so that the clamp has high precision and high stability during the adjustment process.

[0055] like Figure 2 As shown: a pressure sensor is arranged inside the silicone gasket, and the pressure sensor is connected to the controller 4. A harness portion 33 is arranged outside the protective shell 32, and a harness is arranged on the harness portion 33. One end of the harness is connected to the controller 4, and the other end is connected to the micro-adjusting cylinder 26. The head support 23 is made of soft silicone and is installed in the middle of the clamp seat 24.

[0056] In this embodiment, the design of the headrest 23 adopts ergonomic principles, and its soft material can provide comfortable support. At the same time, the installation position of the headrest 23 is located in the middle of the clamp seat 24, which can ensure that the head always maintains a correct posture during use.

[0057] Under the guidance of the controller 4, the pressure sensor inside the silicone gasket can monitor the pressure changes of the user's head in real time, and accurately control the micro-adjusting cylinder 26 through the controller 4, thereby achieving the adjustment of the head support force.

[0058] The design of the harness part 33 is to organize and store the harness, avoid the disorder of the cables, and improve the neatness of the product appearance. One end of the harness is connected to the controller 4, and the other end is connected to the micro-adjusting cylinder 26. This design not only ensures the smooth flow of the line, but also makes the operation of the entire system more stable.
