[0007] Furthermore, a circular limiting groove is formed in the hollow tube, a circular limiting plate is fixedly installed at the front end of the round rod, and the circular limiting plate is slidably connected with the circular limiting groove.

[0008] Furthermore, two prompting round rods are fixedly installed on the back surface of the circular limiting plate, the ends of the two prompting round rods both extend outside the hollow tube and are slidably connected with the hollow tube, a prompting round plate is fixedly sleeved on the round rod, the two prompting round rods both penetrate through the supporting airbag and are slidably connected with the supporting airbag, and the ends of the two prompting round rods are both in contact with the prompting round plate.

[0009] Furthermore, two supporting springs are fixedly installed on the back surface of the hollow tube, a circular fixing plate is fixedly sleeved on the round rod, the ends of the two supporting springs are both fixedly connected with the circular fixing plate, and the two prompting round rods respectively penetrate through the two supporting springs.

[0010] Furthermore, an exhaust mechanism is arranged in the hollow tube, the exhaust mechanism includes a circular filter plate fixedly installed in the hollow tube, a U-shaped perforated round plate is slidably installed in the hollow tube, the end of the rectangular rod is fixedly connected with the U-shaped perforated round plate, an exhaust spring is fixedly installed on the front surface of the circular filter plate, the front end of the exhaust spring is fixedly connected with the U-shaped perforated round plate, and a plurality of exhaust holes are formed in the outer wall of the hollow tube.

[0011] Furthermore, a telescopic mechanism is arranged in the hollow tube, the telescopic mechanism includes a circular installation block fixedly installed in the hollow tube, a T-shaped circular groove is formed in the circular installation block, a T-shaped hollow slider is slidably installed in the T-shaped circular groove, and a telescopic spring is fixedly installed on the inner wall of the front end of the hollow tube.

[0012] Furthermore, a plurality of through holes are formed in the front surface of the T-shaped hollow slider, a plurality of exhaust round holes are formed in the outer wall of the T-shaped hollow slider, and the plurality of through holes are communicated with the plurality of exhaust round holes.

[0013] The present invention has the following beneficial effects: (1) The present invention is a leak-proof cover for a uterine manipulator for laparoscopic hysterectomy in gynecology. First, the device is placed into the vagina so that the circular plate on the round rod is exposed. The device is kept straight and stable during the placement into the vagina to prevent the device from tilting. When the device enters the vagina, a plurality of arc-shaped wiping sponges will move directly close to the inner wall of the vagina. During the movement, the arc-shaped wiping sponges will wipe and absorb the secretions and liquids in the vagina. Due to the different diameters of the vagina, the wiping spring will be compressed when encountering a small diameter position. In the place where the vagina has a large diameter, the wiping spring will be elastic and make the arc-shaped wiping sponge always move close to the vaginal wall, so that the arc-shaped wiping sponge can flexibly and effectively wipe the secretions on the inner wall of the vagina, and prevent the device from being easily deviated from the angle due to the lubrication of the secretions in the vagina, causing carbon dioxide leakage; (2) The present invention is used for the leak-proof air cover of the uterine manipulator for laparoscopic hysterectomy in gynecology. After the device is pushed into the vagina, air is supplied to the support airbag 1 through the air supply tube. The support airbag 1 will pass the gas into the support airbag 2 through the hose. The gas in the support airbag 2 will enter the hollow tube along the through groove. When the gas in the support airbag 1 and the support airbag 2 reaches a certain amount, the air pressure will increase, and the gas will enter the T-shaped hollow slider through the through hole. The gas will then push the T-shaped hollow slider to move in the direction close to the round rod. When the position of the exhaust circular hole leaves the circular mounting block, the gas will be discharged from the exhaust circular hole. As the gas is continuously input, the air pressure will push the round rod and the hollow tube away from each other. At this time, the distance between the support airbag 1 and the support airbag 2 will also become longer, further enhancing the stability of the device in the vagina and reducing the possibility of angular deviation of the device. (3) The present invention is used for the anti-leakage air cover of the uterine manipulator for laparoscopic hysterectomy in gynecology. In the process that the round rod and the hollow tube move away from each other, the round limit plate will slide along the round limit groove and stop when the round limit plate contacts the inner wall of the back side of the round limit groove. When the round limit plate contacts the round limit groove, the corresponding prompt round rod will contact the prompt round plate with the round limit plate. At this time, when the staff sees that the prompt round rod contacts the prompt round plate, they can notify the gas supply to the gas supply pipe. At this time, the gas in the support airbag 2 and the support airbag 1 is in the maximum saturation state. The function of the prompt round rod and the prompt round plate can effectively understand the state of the support airbag 1 and the support airbag 2, so as to avoid the phenomenon that the vagina leaks or expands due to too much or too little gas, causing physical discomfort to the patient; (4) The air leakage prevention cover of the uterine manipulator for gynecological laparoscopic total hysterectomy according to the present invention. During the operation, if the hollow tube extends too long and blocks the organs in the abdominal cavity, manually pull the circular block, and the circular block will drive the rectangular rod to move away from the round rod. The rectangular rod drives the U-shaped perforated circular plate away from the exhaust hole. At this time, the gas between the U-shaped perforated circular plate and the round rod will be discharged from the exhaust hole outside the device. At this time, push the second support airbag, and the second support airbag will drive the hollow tube to move towards the round rod. Since a part of the gas between the round rod and the hollow tube is released, the hollow tube will be easier to move towards the round rod. Since the arc-shaped wiping sponge wipes the secretions on the inner wall of the vagina, after the second support airbag moves, it will still maintain the stability of the device under the action of the friction force between it and the inner wall of the vagina.

[0014] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is an air leakage prevention cover for a uterine lifting device used in gynecological laparoscopic total hysterectomy, including a round rod 1. A hollow tube 2 is slidably sleeved on the outer wall of the round rod 1. A rectangular rod 3 is slidably installed in the hollow tube 2. The front end of the rectangular rod 3 extends outside the hollow tube 2. A circular block 4 is fixedly installed at the front end of the rectangular rod 3. It further includes: An erasing mechanism 5. The erasing mechanism 5 includes a plurality of rectangular grooves 501 opened in the circular block 4. Erasing springs 502 are respectively fixedly installed on the inner walls of the plurality of rectangular grooves 501 close to each other. The ends of the plurality of erasing springs 502 away from each other are respectively fixedly installed with rectangular sliding rods 503. The ends of the plurality of rectangular sliding rods 503 away from each other respectively slide and extend outside the circular block 4. Arc-shaped wiping sponges 504 are respectively fixedly installed at the ends of the plurality of rectangular sliding rods 503 away from each other.

[0020] As Figure 2 shown, a supporting airbag I 505 is fixedly installed on the round rod 1. A supporting airbag II 506 is fixedly installed on the outer wall of the hollow tube 2. A plurality of through grooves 507 are opened on the inner wall of the supporting airbag II 506. The plurality of through grooves 507 are all communicated with the hollow tube 2. A plurality of hoses 508 are fixedly installed at the front end of the supporting airbag I 505. The front ends of the plurality of hoses 508 are all communicated with the supporting airbag II 506. An air delivery pipe 509 is fixedly installed at the end of the supporting airbag I 505.

[0021] After the device is pushed into the vagina, air is supplied to the support airbag 1 505 through the air supply tube 509. The support airbag 1 505 will pass the gas into the support airbag 2 506 through the hose 508. The gas in the support airbag 2 506 will enter the hollow tube 2 along the through groove 507. When the gas in the support airbag 1 505 and the support airbag 2 506 reaches a certain amount, the air pressure will increase.

[0022] like Figure 7 As shown, a circular limiting groove 510 is opened in the hollow tube 2 , and a circular limiting plate 511 is fixedly installed at the front end of the round rod 1 , and the circular limiting plate 511 is slidably connected to the circular limiting groove 510 .

[0023] When the round rod 1 and the hollow tube 2 move away from each other, the circular limiting plate 511 will slide along the circular limiting groove 510 , and stop when the circular limiting plate 511 contacts the back inner wall of the circular limiting groove 510 .

[0024] like Figure 5 As shown, two reminder round rods 512 are fixedly installed on the back side of the circular limiting plate 511, and the ends of the two reminder round rods 512 extend outside the hollow tube 2 and are slidably connected to the hollow tube 2. A reminder round plate 513 is fixedly sleeved on the round rod 1, and the two reminder round rods 512 penetrate the supporting airbag 1 505 and are slidably connected to the supporting airbag 1 505, and the ends of the two reminder round rods 512 are in contact with the reminder round plate 513.

[0025] When the circular limiting plate 511 contacts the circular limiting groove 510, the corresponding prompt circular rod 512 will contact the prompt circular plate 513 along with the circular limiting plate 511. At this time, when the staff sees that the prompt circular rod 512 contacts the prompt circular plate 513, they can notify the gas supply to the gas supply pipe 509. At this time, the gas in the support airbag 2 506 and the support airbag 1 505 is in the maximum saturation state. The functions of the prompt circular rod 512 and the prompt circular plate 513 can effectively understand the status of the support airbag 1 505 and the support airbag 2 506, and avoid the phenomenon of vaginal leakage or expansion due to too much or too little gas, which may cause physical discomfort to the patient.

[0026] like Figure 5 and Figure 7 As shown, two support springs 514 are fixedly installed on the back of the hollow tube 2, a circular fixing plate 515 is fixedly sleeved on the round rod 1, the ends of the two support springs 514 are fixedly connected to the circular fixing plate 515, and the two prompt round rods 512 pass through the two support springs 514 respectively.

[0027] During the process of the round rod 1 moving away from the hollow tube 2, the corresponding support spring 514 will undergo tensile deformation. During the process of pushing the hollow tube 2 towards the round rod 1, at this time, the support spring 514 will, under the action of elastic force, cooperate with the manually pushed force to enable the hollow tube 2 to slide more smoothly in the vagina.

[0028] As Figure 8 shown, an exhaust mechanism 6 is provided inside the hollow tube 2. The exhaust mechanism 6 includes a circular filter plate 601 fixedly installed inside the hollow tube 2. A U-shaped perforated circular plate 602 is slidably installed inside the hollow tube 2. The end of the rectangular rod 3 is fixedly connected to the U-shaped perforated circular plate 602. An exhaust spring 603 is fixedly installed on the front surface of the circular filter plate 601. The front end of the exhaust spring 603 is fixedly connected to the U-shaped perforated circular plate 602. A plurality of exhaust holes 604 are formed on the outer wall of the hollow tube 2.

[0029] During the operation, if the hollow tube 2 extends too long and blocks the organs in the abdominal cavity, manually pull the circular block 4. The circular block 4 will drive the rectangular rod 3 to move away from the round rod 1. The rectangular rod 3 drives the U-shaped perforated circular plate 602 to leave the position of the exhaust hole 604. At this time, the gas between the U-shaped perforated circular plate 602 and the round rod 1 will be discharged outside the device through the exhaust hole 604. At this time, push the support airbag two 506. The support airbag two 506 will drive the hollow tube 2 to move towards the round rod 1. Since a part of the gas between the round rod 1 and the hollow tube 2 is released, at this time, the hollow tube 2 will be easier to move towards the round rod 1. Since the arc-shaped wiping sponge 504 wipes the secretions on the inner wall of the vagina, after the support airbag two 506 moves, it will still maintain the stability of the device under the action of the friction force between it and the inner wall of the vagina.

[0030] As Figure 6 shown, a telescopic mechanism 7 is provided inside the hollow tube 2. The telescopic mechanism 7 includes a circular mounting block 701 fixedly installed inside the hollow tube 2. A T-shaped circular groove 702 is formed inside the circular mounting block 701. A T-shaped hollow slider 703 is slidably installed inside the T-shaped circular groove 702. A telescopic spring 704 is fixedly installed on the inner wall of the front end of the hollow tube 2. The end of the telescopic spring 704 is fixedly connected to the T-shaped hollow slider 703.

[0031] The increase in gas pressure will push the T-shaped hollow slider 703 to slide towards the round rod 1. At this time, the telescopic spring 704 undergoes tensile deformation. When the air pressure between the round rod 1 and the hollow tube 2 is equal to the air pressure in the area in front of the circular mounting block 701, the telescopic spring 704 will, under the action of elastic force, reset the T-shaped hollow slider 703 to form a sealed space again.

[0032] As Figure 6As shown, a plurality of through holes 705 are provided on the front of the T-shaped hollow slider 703 , a plurality of exhaust circular holes 706 are provided on the outer wall of the T-shaped hollow slider 703 , and the plurality of through holes 705 are communicated with the plurality of exhaust circular holes 706 .

[0033] When the position of the exhaust hole 706 leaves the circular mounting block 701, the gas will be discharged from the exhaust hole 706. As the gas is continuously input, the air pressure will push the round rod 1 and the hollow tube 2 away from each other. At this time, the distance between the support airbag 1 505 and the support airbag 2 506 will also become longer, further enhancing the stability of the device in the vagina and reducing the possibility of angular deviation of the device.

[0034] When in use, first put the device into the vagina so that the prompt circular plate 513 on the round rod 1 is exposed to the outside. The device is kept upright and stable during the process of being put into the vagina to avoid the device from tilting. When the device enters, several arc-shaped wiping sponges 504 will move directly close to the inner wall of the vagina. The arc-shaped wiping sponges 504 will wipe and absorb the secretions and liquids in the vagina during the movement. Due to the different diameters of the vagina, the erasing spring 502 will be compressed when encountering a small diameter position. In the place where the vagina has a large diameter, the erasing spring 502 will make the arc-shaped wiping sponge 504 always move close to the vaginal wall under the action of elasticity, so that the arc-shaped wiping sponge 504 can flexibly and effectively wipe the secretions on the inner wall of the vagina, and avoid the device in the vagina. The angle is easily deviated due to the lubrication of the secretions and causes the leakage of carbon dioxide; after the device is pushed into the vagina, it starts to pass The air delivery tube 509 delivers air to the supporting airbag 1 505, and the supporting airbag 1 505 will pass the gas into the supporting airbag 2 506 through the hose 508. The gas in the supporting airbag 2 506 will enter the hollow tube 2 along the through groove 507. When the gas in the supporting airbag 1 505 and the supporting airbag 2 506 reaches a certain amount, the air pressure will increase, and the gas will enter the T-shaped hollow slider 703 through the through hole 705. The gas will then push the T-shaped hollow slider 703 to move in the direction close to the round rod 1. When the position of the exhaust circular hole 706 leaves the circular mounting block 701, the gas will be discharged from the exhaust circular hole 706. As the gas is continuously input, the air pressure will push the round rod 1 and the hollow tube 2 away from each other. At this time, the distance between the supporting airbag 1 505 and the supporting airbag 2 506 will also become longer, further enhancing the stability of the device in the vagina and reducing the possibility of the device angular deviation. During the process of the round rod 1 and the hollow tube 2 moving away from each other, the circular limit plate 511 will slide along the circular limit groove 510 and stop when it contacts the inner wall of the back of the circular limit groove 510. When the circular limit plate 511 contacts the circular limit groove 510, the corresponding prompt round rod 512 will contact the prompt round plate 513 following the circular limit plate 511. At this time, when the staff sees the prompt round rod 512 contacting the prompt round plate 513, they can notify to supply gas to the gas transmission pipe 509. At this time, the gas in the second support airbag 506 and the first support airbag 505 is in the maximum saturation state. The functions of the prompt round rod 512 and the prompt round plate 513 can effectively understand the states of the first support airbag 505 and the second support airbag 506, and avoid the phenomenon that the vagina leaks air or expands due to too much or too little gas, causing discomfort to the patient's body. During the operation, if the hollow tube 2 extends too long and blocks the organs in the abdominal cavity, manually pull the circular block 4, and the circular block 4 will drive the rectangular rod 3 to move away from the round rod 1. The rectangular rod 3 drives the C-shaped perforated round plate 602 to leave the position of the exhaust hole 604. At this time, the gas between the C-shaped perforated round plate 602 and the round rod 1 will be discharged outside the device from the exhaust hole 604. At this time, push the second support airbag 506, and the second support airbag 506 will drive the hollow tube 2 to move towards the round rod 1. Since a part of the gas between the round rod 1 and the hollow tube 2 is released, the hollow tube 2 will be easier to move towards the round rod 1. Since the arc-shaped wiping sponge 504 wipes the secretions on the inner wall of the vagina, after the second support airbag 506 moves, it will still maintain the stability of the device under the action of the friction force between it and the inner wall of the vagina.
