Description

Technical Field

[0001] This utility model relates to the field of cesarean section instrument manufacturing, specifically a U-shaped cesarean section single aluminum strip bending fixture. Background Technology

[0002] Cesarean section generally refers to a cesarean delivery. A cesarean section is a surgical method of delivery that removes the baby from the mother's uterus. Its benefits include avoiding the risk of dystocia, handling emergencies, reducing birth canal damage, preventing vaginal infections, allowing for planned delivery, and avoiding the long-term effects of vaginal delivery. Cesarean section instruments require a U-shaped aluminum strip. Currently, there are machines on the market that can bend steel strips of a certain thickness by radius or geometry, such as copper pipe bending machines or industrial aluminum strip bending machines. These bending machines generally use a combination of die wheels and pressure wheels to complete the bending. However, for small cross-sectional areas and thin flat surfaces, these machines generally cannot accurately achieve circular arc bending. This requires consideration of the material's elongation and compressibility, as well as factors such as the sharp angles created by folding and wrinkling during the bending process. Without specific molds and techniques, it is generally impossible to complete the bending accurately. Utility Model Content

[0025] This invention is a sterile drape specifically designed for cesarean section surgery. It uses a U-shaped opening to precisely locate the abdominal incision area, reducing the risk of intraoperative contamination. Aluminum strips are used to reinforce the edges, improving structural stability and preventing displacement or tearing during surgery. This invention effectively solves the problem of deformation and wrinkles that occur during the bending of aluminum strips, ensuring that the curved edges of the bend are flat and form the required dimensions.

[0026] Please see Figure 1-5 A U-shaped cesarean section single aluminum strip bending fixture includes a first dual-axis cylinder 1 and a second dual-axis cylinder 2, a bending guide block 10, a fixing guide block 11 and a base plate 12; the first dual-axis cylinder 1 and the second dual-axis cylinder 2 are selected to effectively prevent unnecessary rotational movements during work, and this actuator is the power source of the entire mechanism.

[0027] The first dual-axis cylinder 1 is mounted on the first cylinder mounting plate 3, and the second dual-axis cylinder 2 is mounted on the second cylinder mounting plate. The first cylinder mounting plate 3 is fixed to the fixed guide block 11 by the first fixing bolt 5, and the second cylinder mounting plate 4 is fixed to the bending guide block 10 by the first fixing bolt 5. These two cylinder mounting plates are mounted on the fixed guide block 11 and the bending guide block 10 by the first fixing bolt 5 to form a supporting force.

[0028] The fixed guide block 11 is bolted to the base plate 12 and remains stationary. The fixed pressure block 13 is bolted to the first dual-axis cylinder 1 and moves up and down as the cylinder operates. The rotating pressure block 14 is bolted to the second dual-axis cylinder 2 and also moves up and down as the cylinder operates. The bending rotary handle 6 is mounted on the bending guide block 10 for easy gripping by the operator during bending operations. The adjustable positioning strip 7 has a waist-shaped groove and is mounted to the fixed guide block 11 through the groove. It is used to adjust the bending of aluminum strips of different lengths. Figure 2 To understand its function, look at the waist-shaped groove;

[0029] The aluminum strip 16 passes through the fixed pressure block 13 of the first dual-axis cylinder 1 and the rotating pressure block 14 of the second dual-axis cylinder 2. The aluminum strip 16 is placed flat on the mechanism. The fixed pressure block 13 and the rotating pressure block 14 are driven by the operation of the first dual-axis cylinder 1 and the second dual-axis cylinder 2 to press and position it.

[0030] The base plate 12 is provided with a bending guide groove 8, and a ball bearing 21 is provided in the bending guide groove 8. The bending guide block 10 is movably connected to the bending guide groove 8 through the ball bearing 21. The purpose of the bending guide groove 8 is to allow the bending guide block 10 to bend along this trajectory. The ball bearing 21 allows the bending guide block 10 to move along the trajectory in this guide groove while also reducing the plane friction force F.

[0031] The bending guide block 10 is connected to the base plate 12 via the bending positioning post 9; the bending positioning post 9 serves as both a connector between the bending guide block 10 and the base plate 12 and a fulcrum for the bending rotating arm.

[0032] A deep groove ball bearing 17 is installed on the bending guide block 10. A bending positioning post 9 is disposed between the deep groove ball bearing 17 and the base plate 12 on the bending guide block 10. The bottom of the bending positioning post 9 is a threaded section. The bottom of the bending positioning post 9 is connected to the limit nut 18. The limit nut 18 limits the bending positioning post 9 to prevent it from moving upward.

[0033] An adjusting block 20 is provided on the base plate 12, and an adjusting stud 19 is provided inside the adjusting block 20. The adjusting stud 19 is located directly below the bending positioning post 9. The adjusting stud 19 and the limiting nut 18 cooperate to adjust the height of the bending positioning post 9 appropriately. At the same time, the adjusting stud 19 also provides support for the bending positioning post 9.

[0034] The adjusting block 20 is fixed to the base plate 12 by two second fixing bolts 23. The adjusting block 20 is designed in a U-shape to facilitate adjustment.

[0035] A raised step 22 is provided between the fixed guide block 11 and the base plate 12; and the bending guide block 10 is installed on the surface below the step because of the clearance fit between the movement trajectory and the ball 21; the base plate 12 is provided with a support leg 15, which supports the stability of the spore device.

[0036] Figure 5 This is a magnified view of the bend, intended to facilitate understanding of the bending principle of this fixture. Figure 5 As can be seen from the image, the bending positioning post 9 is divided into surfaces A and B by the central cylindrical step. Surface A is the plane of the step, and surface B is the arc surface of the step.

[0037] The fixed guide block 11 is provided with a first aluminum strip placement positioning groove 25; the bending guide block 10 is provided with a second aluminum strip placement positioning groove 24; the aluminum strip 16 passes through the first aluminum strip placement positioning groove 25 and the second aluminum strip placement positioning groove 24; the aluminum strip placement positioning groove is designed and customized according to the size of the aluminum strip, and the bottom surface of the first aluminum strip placement positioning groove 25 and the second aluminum strip placement positioning groove 24 is at the same level as surface A of the bending positioning post 9. This design is to prevent unevenness and misalignment of the aluminum strip during placement, which would affect the bending quality. When the aluminum strip is placed in the groove, the fixed pressure block 13 and the rotating pressure block 14 will press and fix it by the movement of the cylinder. The hole in the fixed pressure block 13 and the cylindrical step of the bending positioning post 9 cooperate to cover the bending area on the A side. When the aluminum strip moves along the bending guide block 10 along the bending positioning post 9, the aluminum strip will bend in an arc close to the B side. At the same time, because the cylindrical step of the bending positioning post 9 presses down on the bending area of ​​the aluminum strip on the A side, the aluminum strip is bent in a smooth arc without any edge flipping when it is bent laterally, thus realizing this type of aluminum strip lateral bending process.

[0038] This utility model is a sterile drape specifically designed for cesarean section surgery. It uses a U-shaped opening to precisely position the abdominal incision area, reducing the risk of intraoperative contamination. The aluminum strip reinforces the edges, improving structural stability and preventing displacement or tearing during surgery. This utility model is a special fixture designed using a U-shaped bending process for the aluminum strip. In cesarean section surgery, the U-shaped aluminum drape, also known as a "U-shaped aluminum drape" or "cesarean section baffle," is a common auxiliary device. The U-shaped aluminum drape isolates the surgical area, maintaining a sterile environment. The U-shaped aluminum strip is usually fixed to the lower edge of the cesarean section drape, such as a sterile sheet, forming a U-shaped or arc-shaped barrier that physically separates the non-sterile area of ​​the mother's head from the sterile area of ​​the abdominal surgery. This prevents droplets generated by the mother's breathing, coughing, or speaking from contaminating the surgical field, reducing the risk of infection. The U-shaped aluminum strip for cesarean section drapes supports the surgical drape, preventing obstruction of the surgical field. The lightweight and malleable aluminum strip provides stable support, preventing the drape from sagging or piling on the mother's chest, ensuring the surgeon has a clear view of the surgical field. It is especially suitable for conscious mothers under spinal or epidural anesthesia, preventing discomfort caused by drape pressure. The U-shaped aluminum strip also protects the mother's airway. In emergency cesarean sections such as under general anesthesia, the U-shaped design provides the anesthesiologist with operating space, facilitating airway management such as intubation or suctioning, while also isolating the abdominal surgical area. The U-shaped aluminum strip is convenient and disposable; it is typically used with disposable cesarean section drapes, is lightweight, requires no sterilization, and reduces the risk of cross-infection. Some products are adjustable to accommodate different mothers' body shapes.

[0039] The main working principle of this utility model is to use a positioning block to position the aluminum strip, and then use a dual-axis cylinder to perform a pressing action, so that the aluminum strip can be fixed on the bending mechanism. A ball bearing is used to complete a hinge-like mechanism to perform the bending motion. The ball bearing and guide groove structure are used to reduce friction and improve work efficiency. The specific working principle has been described in detail above and will not be elaborated here.

[0040] This invention effectively solves the deformation and wrinkles that occur during the flat bending process of aluminum strips, allowing the flat bending arc to form the required actual size. At the same time, the limit length can be adjusted to accommodate bending of aluminum strips of different sizes, and the bending angle can be adjusted to different ranges according to actual needs.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims rather than the foregoing description, and therefore all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
