Description

Technical Field

[0001] This invention relates to the field of animal husbandry and veterinary equipment technology, and in particular to a continuous embryo transfer surgical device. Background Technology

[0002] Embryo transfer technology is considered the second revolution in livestock reproduction after artificial insemination. Since Kvashikii's successful pig embryo transfer experiment in 1951, pig embryo transfer began to be used in the 1970s for international introduction of breeds and for introducing foreign blood into closed herds to improve genes. In the 1980s, it began to be used in the production of transgenic recipient female animals. In recent years, with the maturity of somatic cell cloning, transgenic, and gene editing technologies, more and more new breeds and lines have been developed through bio-breeding techniques. Many institutions at home and abroad have carried out embryo transfer surgeries on cattle, horses, pigs, and sheep, with pig and sheep embryo transfer surgeries being the most numerous. To a certain extent, any embryo-based improvement method requires embryo transfer to produce the target recipient female animal. No matter how well the embryos are prepared in the early stages, without good embryo transfer technology, results cannot be obtained quickly and efficiently. Therefore, the ease of use and efficiency of embryo transfer equipment and methods directly determine the efficiency of converting scientific research into production results.

[0003] Currently, most pig and sheep embryo transfer surgeries are performed in the operating room using a V-shaped (or U-shaped) operating table. The general procedure involves first restraining and anesthetizing the recipient animal in the anesthesia area, then moving it to the operating table for surgery, and finally moving it again to the recovery area for observation. These steps are often separate and independent, resulting in poor continuity and frequent transfers, leading to low overall efficiency. Furthermore, the restraint and anesthesia process requires moving the recipient animal into an anesthesia cage and using multiple assistants to restrain it with harnesses and ropes to restrict movement and ensure the safety of both personnel and the animal. After anesthesia, the restraints must be manually removed, making the entire anesthesia and restraint process cumbersome, time-consuming, and labor-intensive, severely impacting the overall efficiency of the embryo transfer surgery.

[0004] Therefore, it is necessary to provide a continuous embryo transfer surgical device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous embryo transfer surgical device to solve the problems in the above-mentioned background art, where the surgical steps are separated, the operation is not continuous, and the manual restraint operation is cumbersome, resulting in low overall surgical efficiency.

[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a continuous embryo transfer surgery device, comprising an anesthesia device, a restraint surgery device, and a recovery device, wherein the anesthesia device is detachably connected to the restraint surgery device, and the restraint surgery device is detachably connected to the recovery device, and the female animal undergoes continuous embryo transfer surgery sequentially through the anesthesia device, the restraint surgery device, and the recovery device.

[0007] Furthermore, the anesthesia device has a No. 1 door and a No. 2 door movably connected to both ends, and the recovery device has a No. 3 door and a No. 4 door movably connected to both ends. The No. 1 door is located at the entrance of the anesthesia device and is rotatably connected to the anesthesia device. The No. 2 door is movably located at the exit of the anesthesia device. The No. 3 door is a movably located door and is located at the entrance of the recovery device. The No. 4 door is rotatably located at the exit of the recovery device.

[0008] Furthermore, the anesthesia device includes a first ramp, an anesthesia frame, a first transmission belt, a guardrail, a restraint frame, and a lasso. The anesthesia frame is installed between the first door and the second door, and one end of the anesthesia frame extending out of the first door is movably connected to the first ramp.

[0009] The anesthesia frame has a first transmission belt at its bottom, which is a stainless steel non-powered float device. A tray is placed on top of the belt. To facilitate the sliding of the anesthetized animal from the first door to the second door, guardrails are provided on both the front and back sides of the anesthesia frame. A restraint frame is installed at the top of the guardrail on the side away from the first door, and a lasso is installed above the restraint frame. The restraint frame and the lasso are used together to control the position of the female animal. A stainless steel tray, 210cm long and 100cm wide, is placed on top of the transmission belt. The tray is perforated for drainage, and a rubber anti-slip mat is laid on top. Four trays are required, along with four matching rubber mats. The edge height of the tray is 5-10cm.

[0010] Furthermore, the restraint surgery device includes an operating table, the side of the operating table near the second door being 15cm higher than the side near the third door. The operating table surface is composed of multiple polyethylene rollers spaced 5cm apart, and a wastewater storage tank is provided at the bottom of the operating table. The restraint frame is provided at the four corners of the upper part of the operating table, and the middle and upper sections of the restraint frame are provided with restraint rings. The restraint frame and the restraint rings, combined, allow for the restraint of the recipient female animal in a lateral or supine position.

[0011] Furthermore, the operating table has a contaminated surgical instrument cabinet and a monitoring and anesthesia instrument cabinet on the main operating side, and a sterile surgical instrument cabinet and a consumables cabinet on the assistant operating side.

[0012] Furthermore, the revival device includes a second transmission belt, a revival frame, and a second ramp. The revival frame is disposed between the third door and the fourth door. The second transmission belt is laid at the bottom of the revival frame. The first transmission belt is a stainless steel non-powered float device. The end of the revival frame extending out of the fourth door is movably connected to the second ramp.

[0013] Furthermore, the anesthesia device is at the same height as the operating table.

[0014] Furthermore, a crank handle and gear are provided on the outside of the lasso, which are used to quickly tighten or loosen the restraining rope.

[0015] The polyethylene roller is hollow, with a through hole on its outer side. A ball plug is disposed inside the polyethylene roller and can block the through hole. A moving rod is disposed inside the polyethylene roller, and a drive chamber is disposed inside the polyethylene roller. The moving rod passes through the drive chamber and is slidably connected to the drive chamber. A second magnetic sheet is disposed at the end of the moving rod. A sliding chamber is disposed inside the drive chamber and is slidably connected to the second magnetic sheet. A polygonal shaft is also rotatably disposed inside the drive chamber. Multiple first magnetic sheets are attached to the side of the polygonal shaft, and the first magnetic sheets correspond to the second magnetic sheets.

[0016] The number of the first magnetic sheets is twice the number of the second magnetic sheets, and the outward magnetic properties of adjacent first magnetic sheets are opposite;

[0017] The polygonal shaft is fixedly connected to the rotating shaft, and a rotating block is fixedly connected to the end of the rotating shaft. The rotating block is located on the outside of the polyethylene roller, and multiple protrusions are provided on the inner side of the rotating block. Multiple grooves (not shown) that cooperate with the protrusions are provided on the outside of the polyethylene roller. The multiple protrusions are arranged in a ring.

[0018] The rotating block is also provided with sliding grooves on both sides, and a connecting rod is slidably provided in the sliding groove. A clamping ring is fixed at the end of the connecting rod. A first magnetic block is provided on the inner side of the connecting rod, and a pair of second magnetic blocks with opposite magnetism to the first magnetic block are provided on the outer side of the polyethylene roller.

[0019] During cleaning, the cleaning cloth works in conjunction with the polyethylene roller. Rotating the rotating block once moves the protrusion one notch in the groove, so that the first magnetic block aligns with the second magnetic block, preventing the clamping ring from moving up and down at will and providing clamping performance. The edge of the cleaning cloth is bent and clamped into the gap between the clamping ring and the polyethylene roller, so that the edge of the polyethylene roller can be cleaned by the cleaning cloth during cleaning.

[0020] The polyethylene roller contains cleaning fluid. In the initial state, i.e. during the operation of the surgical device, the first magnetic sheet corresponding to the second magnetic sheet has the same magnetism. The second magnetic sheet moves outward in the sliding chamber under the action of magnetic force, which drives the moving rod to block the through hole with the ball plug, so that the cleaning fluid will not overflow. When the rotating block rotates once, i.e. during cleaning, the first magnetic sheet corresponding to the second magnetic sheet has opposite magnetism. The second magnetic sheet moves inward, and the ball plug disengages from the polyethylene roller, causing the cleaning fluid to overflow, thus realizing the self-cleaning of the polyethylene roller.

[0021] The device can switch between cleaning and surgical modes by rotating the rotating block. In cleaning mode, the clamping ring can clamp the edge of the cleaning cloth, allowing the cleaning cloth to clean the edge of the polyethylene roller. The ball plug moves inward, causing the cleaning fluid to overflow, so that the cleaning cloth can further clean and disinfect the polyethylene roller under the action of the cleaning fluid, making it more convenient for the continuous operation of the Baoding surgical device.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Design an anesthesia device at the same height as the operating table. Use the first ramp to drive the recipient female animal to the anesthesia area for restraint and anesthesia, thus solving the problem of needing to manually move the recipient female animal after restraint and anesthesia on the ground, and improving transplantation efficiency.

[0024] 2. The entire process uses a combination of conveyor belts and ramps to quickly and horizontally transport the recipient female animals. The female animals can walk up and down the continuous embryo surgery device on their own, reducing the intensity of manual labor.

[0025] 3. The combination of the restraint frame and the restraint ring allows for multiple restraint conversion methods (side-lying or supine) according to the experimental needs of the recipient female animal.

[0026] 4. By designing a special stainless steel tray, surgical wastewater can be leaked into the wastewater collection tank below, significantly reducing biosafety risks;

[0027] 5. By integrating the operating table with the cabinets for contaminated surgical instruments, sterile surgical instruments, monitoring and anesthesia instruments, and consumables, all auxiliary instruments are stored in separate sections and categories, making them convenient to use and organize.

[0028] 6. By connecting the anesthesia device, the restraint surgery device, and the recovery device, the second recipient female animal can be anesthetized immediately after the first recipient female animal has undergone surgery, without waiting. This allows staff to work continuously and improves the efficiency of embryo transfer.

[0029] 7. The design of the resuscitation device facilitates the observation of the recipient female animal's postoperative condition, prevents postoperative accidents, and ensures the success rate of transplantation; at the same time, the device can also be used for various surgeries such as live oocyte collection, live embryo flushing, and cesarean section.

[0042] The present invention will be further described below with reference to embodiments.

[0043] like Figure 1-5As shown, a continuous embryo transfer surgical device includes: an anesthesia device; a restraint device; and a recovery device. These three devices are pushed together during use, with the anesthesia device in front, its second door pressed against the higher side of the restraint device, and the two devices connected by hooks; the restraint device is in the middle, its lower end pressed against the recovery device, which is located at the rear.

[0044] Anesthesia devices such as Figure 1 As shown, the anesthesia frame 22 is 40-80cm high above the ground, 200-220cm long, and 80-100cm wide. A movable first ramp 21 is installed on the front bottom plate frame of door 11, which can be folded up when not in use and lowered when needed.

A restraint frame 25 is provided on the top of the side of the guardrail 24 away from door 11, and a lasso 26 is provided above the restraint frame 25. The restraint frame 25 and the lasso 26 are used together to control the position of the female animal. The guardrails 24 on both sides are designed to be movable, allowing for easy adjustment of the width to clamp the female animal according to its size, and can be quickly released after restraint.

[0045] Baoding surgical devices such as Figure 3-5 As shown, the operating table is 200-220cm long and 80cm wide, made of polyethylene rollers 32 laid at 5cm intervals, with a stainless steel tray 33 on top, which can leak disinfectant and surgical wastewater; a wastewater storage tank 31 is set under the operating table to collect wastewater, with the same area as the operating table; the bottom plate of door No. 2 is 50-60cm high from the ground, and the bottom plate of door No. 3 is 35-45cm high from the ground, forming a head-low and tail-high position; restraint frames 25 are set at the four corners of the top of the operating table, with two fixing rings installed on the four uprights of the restraint frame, which can use different methods (lateral or supine) to restrain the recipient female animal according to the surgical plan; the main operating side of the operating table is equipped with a contaminated surgical instrument cabinet and a monitoring and anesthesia instrument cabinet, and the assistant operating table is also equipped with a sterile surgical instrument cabinet and a consumables cabinet.

[0046] Awakening devices such as Figure 2 As shown, a second conveyor belt with stainless steel floats is laid at the bottom of the wake-up rack. The stainless steel tray is manually pushed to rotate only towards door No. 4. The wake-up rack is 200-220cm long and 80-100cm wide. Door No. 3 is a pull-out design, which is pushed in when in use and pulled out when not in use. Door No. 3 is 35-45cm above the ground, and door No. 4 is 35-45cm above the ground. The wake-up rack frame at the rear of door No. 4 is equipped with an up-and-down movable ramp, which is folded up when not in use and lowered when in use.

[0047] The anesthesia device, the restraint surgery device, and the recovery device are connected by hooks.

[0048] The above-mentioned technical features have the following beneficial effects:

[0049] Improved surgical efficiency: The device is rationally designed, with three interconnected devices that work together to realize the entire process of continuous embryo transfer surgery, making the surgical process smoother, reducing surgical time, and improving surgical efficiency.

[0050] Reduce surgical risks: The device has complete anesthesia, restraint, and recovery functions, which can effectively control the position and physical condition of the female animal, reduce unexpected situations during surgery, and lower surgical risks.

[0051] Improve surgical success rate: The operating table of this equipment is 200-220cm long and 80cm wide. The surgical drape is covered with perforated canvas, which can keep the surgical area warm and dry, while allowing disinfectant and surgical waste to leak, ensuring the cleanliness and hygiene of the surgical area and improving the surgical success rate.

[0052] Improving the protection level of recipient female animals: The restraint surgical device of this equipment can adjust the width of the clamp to hold the recipient female animal according to its size. It can be quickly released after restraint. The flexible design meets the protection requirements of recipient female animals and can protect the life and health of recipient female animals to the greatest extent.

[0053] Improve work efficiency: The device has a reasonable design for the surgeon's area and the assistant's area on the opposite side. The surgical instruments and consumables are placed in separate areas on the left and right sides, which can make the surgeons work in an orderly manner and improve work efficiency.

[0054] The polyethylene roller 32 is hollow and has a through hole on its outer side. A ball plug 44 is disposed inside the polyethylene roller 32 and can block the through hole. A moving rod 45 is disposed inside the polyethylene roller 32. A drive chamber 47 is disposed inside the polyethylene roller 32. The moving rod 45 passes through the drive chamber 47 and is slidably connected to the drive chamber 47. The end of the moving rod 45 is provided with a second magnetic sheet 51. A sliding chamber 50 is disposed inside the drive chamber 47 and is slidably connected to the second magnetic sheet 51. A polygonal shaft 48 is also rotatably disposed inside the drive chamber 47. A plurality of first magnetic sheets 49 are attached to the side of the polygonal shaft 48. The first magnetic sheets 49 correspond to the second magnetic sheets 51.

[0055] The number of the first magnetic sheet 49 is twice the number of the second magnetic sheet 51, and the outward magnetic properties of adjacent first magnetic sheets 49 are opposite.

[0056] The polygonal shaft 48 is fixedly connected to the rotating shaft 46. A rotating block 52 is fixedly connected to the end of the rotating shaft 46. The rotating block 52 is located on the outside of the polyethylene roller 32. Multiple protrusions 53 are provided on the inner side of the rotating block 52. Multiple grooves (not shown) that cooperate with the protrusions 53 are provided on the outer side of the polyethylene roller 32. The multiple protrusions 53 are arranged in a ring.

[0057] The rotating block 52 is also provided with sliding grooves 59 on both sides. A connecting rod 54 is slidably provided in the sliding groove 59. A clamping ring 56 is fixedly provided at the end of the connecting rod 54. A first magnetic block 55 is provided on the inner side of the connecting rod 54. A pair of second magnetic blocks 57 with opposite magnetism to the first magnetic block 55 are provided on the outer side of the polyethylene roller 32.

[0058] During cleaning, the cleaning cloth 58 cooperates with the polyethylene roller 32. Rotating the rotating block 52 once causes the protrusion 53 to move one notch in the groove, so that the first magnetic block 55 corresponds to the second magnetic block 57, preventing the clamping ring 56 from moving up and down at will and providing clamping performance. The edge of the cleaning cloth 58 is bent and clamped into the gap between the clamping ring 56 and the polyethylene roller 32, so that the edge of the polyethylene roller 32 can be cleaned by the cleaning cloth 58 during cleaning.

[0059] The polyethylene roller 32 contains cleaning fluid. In the initial state, that is, during the operation of the restraint surgical device, the first magnetic piece 49 corresponding to the second magnetic piece 51 has the same magnetism. The second magnetic piece 51 moves outward in the sliding chamber under the action of magnetic force, which drives the moving rod 45 to block the through hole with the ball plug 44, so that the cleaning fluid will not overflow. When the rotating block 52 rotates once, that is, during cleaning, the first magnetic piece 49 corresponding to the second magnetic piece 51 has opposite magnetism. The second magnetic piece 51 moves inward, and the ball plug 44 disengages from the polyethylene roller 32, causing the cleaning fluid to overflow, thus realizing the self-cleaning of the polyethylene roller 32.

[0060] The device can switch between cleaning and surgical modes by rotating the rotating block 52. In the cleaning mode, the clamping ring can clamp the edge of the cleaning cloth, allowing the cleaning cloth to clean the edge of the polyethylene roller. The ball plug moves inward, causing the cleaning liquid to overflow, so that the cleaning cloth can further clean and disinfect the polyethylene roller under the action of the cleaning liquid, making it more convenient for the continuous operation of the Baoding surgical device.

[0061] The inventiveness of this invention is mainly reflected in the following aspects:

[0062] Rational Design: This invention provides a continuous and efficient workflow for transplantation surgery through the rational design of positioning stalls, anesthesia areas, surgical areas, conveyor belts, and other facilities. This helps improve surgical efficiency and reduce surgical time and the suffering of the recipient animal.

[0063] Humanized operation: By using restraint frames and lassos, the recipient female animal is fixed in a suitable position, avoiding movement and surgical risks during the operation. At the same time, the equipment is easy to operate, reducing the workload of medical staff.

[0064] Anesthesia and Recovery Management: This invention provides unified management of recipient female animals by setting up an anesthesia area and a recovery area. Anesthesia is induced in the anesthesia area to ensure the stability of the recipient female animal during surgery; after surgery, the recipient female animal is transferred to the recovery area to observe its recovery and ensure postoperative safety.

[0065] Flexible restraint methods: This invention provides two restraint methods—lateral decubitus and supine decubitus—to suit different surgical needs. This flexibility can adapt to different surgical requirements and improve the success rate of surgery.

[0066] Promoting Postoperative Recovery: This invention focuses on the recovery of recipient female animals after surgery. It observes the recipient female animals by stopping feeding but not watering, and provides moderate activity to promote the restoration of uterine position and prevent fallopian tube adhesions, which helps to improve the quality of life and success rate of surgery for recipient female animals after surgery.

[0067] In summary, this invention provides an innovative, efficient, and humane equipment solution for embryo transfer surgery. By improving the surgical procedure, increasing surgical efficiency, and focusing on the welfare of the recipient female animal, this invention demonstrates significant inventiveness.

[0068] The self-cleaning design of polyethylene rollers: By incorporating structures such as ball plugs, through holes, and moving rods inside the polyethylene roller, and using magnetic force to control the ball plugs to block or open the through holes, the cleaning fluid inside the polyethylene roller overflows when needed, thus achieving self-cleaning. This design saves cleaning time, improves cleaning effectiveness, and helps maintain a hygienic and safe surgical environment.

[0069] The magnetically controlled clamping ring design utilizes grooves, connecting rods, clamping rings, and magnetic blocks on both sides of the rotating block to ensure the cleaning cloth edge is securely held in place. In the cleaning state, the first and second magnetic blocks exhibit opposite magnetic properties, allowing the clamping ring to stably hold the cleaning cloth in place. This design improves the tightness of contact between the cleaning cloth and the polyethylene roller, facilitating more effective cleaning of the polyethylene roller edges.

[0070] The rotating block enables state switching: This invention achieves switching between cleaning and surgical states by rotating the rotating block. In cleaning state, the protrusion moves one notch within the groove, aligning the first magnetic block with the second magnetic block. At this time, the cleaning cloth can tightly adhere to the polyethylene roller, ensuring effective cleaning. This design simplifies operation and improves equipment efficiency.

[0071] Further cleaning and disinfection: The cleaning solution mentioned in the invention can further clean and disinfect during the cleaning process, ensuring that the surgical apparatus remains in good hygienic condition during continuous operation. This helps reduce the risk of infection and improve the success rate of surgery.

[0072] In summary, this invention utilizes innovative designs such as magnetic control, self-cleaning, and state switching to improve the cleaning effect, efficiency, and safety of the Baoding surgical device.

[0073] Furthermore, the self-cleaning design of the polyethylene roller works in conjunction with the design of the magnetically controlled clamping ring. When the cleaning fluid overflows through the through-hole, the magnetically controlled clamping ring tightly secures the edge of the cleaning cloth, ensuring close contact between the cleaning cloth and the polyethylene roller. In this way, under the action of the cleaning fluid, the cleaning cloth can more effectively clean the edge of the polyethylene roller, improving the cleaning effect.

[0074] The rotating block enables state switching, which works in conjunction with the magnetically controlled clamping ring design. In the cleaning state, the rotating block moves the protrusion one notch within the groove, aligning the first magnetic block with the second. At this time, the clamping ring stably holds the cleaning cloth, ensuring a tight fit between the cloth and the polyethylene roller. This interaction between state switching and magnetic control simplifies operation and improves equipment efficiency.

[0075] The self-cleaning design of the polyethylene roller and the state switching mechanism of the rotating block work together. In the cleaning state, the rotating block switches the state, causing the ball plug to disengage from the polyethylene roller, allowing the cleaning fluid to overflow. This process, in conjunction with the self-cleaning design of the polyethylene roller, ensures the effective utilization of the cleaning fluid and guarantees the cleaning effect of the polyethylene roller.

[0076] In summary, the technical features of this invention interact and support each other, achieving a synergistic effect in cleaning. This close cooperation between features not only improves the cleaning effect of the surgical device but also simplifies the operation and increases the efficiency of the equipment.

[0077] The method of using this device is as follows:

[0078] 1. 24 hours before the operation, the selected recipient female animal was bathed and disinfected, then placed in a positioning pen and fed but not watered to prepare for the operation.

[0079] 2. At the start of the surgery, the positioning bar is opened, and the recipient female animal is driven to the anesthesia area;

[0080] 3. Insert door 2, open door 1, and drive the recipient female animal into the cage via the ramp (head facing door 2). Close door 1. Push one side of the guardrail to clamp the recipient female animal, and use a lasso and restraint frame to restrain her. The assistant induces anesthesia in the recipient female animal. When the recipient female animal is unsteady on her feet, the guardrail can be loosened, and the handle can be turned to slowly loosen the restraint rope so that the recipient female animal lies down. Unlasso the animal. Pull out door 2 and push the stainless steel tray to transfer the recipient female animal to the surgical area.

[0081] 4. Pull the stainless steel tray to move the recipient female animal to the appropriate position on the operating table. Use different restraint methods (lateral or supine) to restrain the recipient female animal's limbs to the restraint rings as needed for the surgery. Maintain anesthesia and ECG monitoring, and begin the surgery. After the surgery, release the restraints, loosen the limbs, and pull out door number 3. Pull the stainless steel tray to transfer the recipient female animal that has completed the surgery to the recovery area.

[0082] 5. Insert through gate number 3, drive the next recipient female animal into the anesthesia area, tidy up the operating table and equipment, and begin a new round of embryo transfer;

[0083] 6. After the recipient female animal has regained consciousness, open Gate 4 and slowly move her to the pre-operative preparation and positioning pen. Stop feeding her but keep her watering her to observe her recovery after the surgery. If possible, she can also be moved to a large pen for separate feeding. Moderate activity can promote uterine repositioning and prevent adhesions.

[0084] The beneficial effects of this method of use include, but are not limited to:

[0085] Preoperative preparation: Disinfecting the recipient female animal and stopping feeding but not watering within 24 hours before surgery can improve the success rate of surgery and reduce the occurrence of postoperative complications.

[0086] Anesthesia: Anesthetizing the recipient female animal can reduce pain and discomfort during surgery, as well as reduce the risk of postoperative bleeding and infection.

[0087] Restraint: Restraining the recipient female animal on the operating table using a lasso and restraint frame can ensure the safety and stability of the recipient female animal during the operation, and can also improve the efficiency of the operation.

[0088] Monitoring: During the operation, electrocardiographic monitoring and anesthesia maintenance of the recipient female animal can promptly detect and address any potential problems, ensuring the safety and success of the operation.

[0089] Recovery: After the surgery, the recipient female animal is sent to the recovery area for observation and recovery. This can reduce the occurrence of postoperative complications and ensure that the recipient female animal can recover as soon as possible.

[0090] Environment: Postoperative observation and care of the recipient female animal can ensure its health and growth, and also reduce the occurrence of complications.

[0091] Manual method: The entire process of embryo transfer can be completed by only 3-4 people in an assembly line style, and the time for each operation can be shortened to within 30-40 minutes. Compared with the traditional method, it can save 3-4 people and shorten the operation time by 10-20 minutes.
