[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. By adjusting the distance between the two supports to match the size of the incision, the left and right supports are connected by the outer airbag and the inner airbag to support the incision that the support body cannot support. By ventilating the inner airbag, the inner airbag is expanded, thereby ensuring that when adjusting the distance between the supports, the inner airbag can be extended and supported between the two supports. By ventilating the outer airbag, the outer airbag is supported to support the incision and fits the incision more closely. By ventilating from the air exchange port into the sealing cylinder, the piston pushes the piston rod to move, thereby driving the support rod 2 to move, and adjusting the distance between the left and right supports.

[0013] 3. A slide rail is provided for installing the rigid plate, and the rigid plate can be taken out from the slide rail. The elastic plate is supported in the slide rail to prevent the rigid plate and the elastic plate from sliding easily. Therefore, when the medical staff holds the rigid plate to hold the entire protective device, the rigid plate is not easy to slide relative to the slide rail. When the position of the rigid plate and the elastic plate relative to the support body needs to be adjusted, the position of the rigid plate can be adjusted by pressing the elastic plate so that the elastic plate is deformed and does not contact the slide rail.

A piston rod 204 is fixedly installed on the right end of the piston 205. A support rod 208 is fixedly installed on the right end of the piston rod 204. The bottom end of the support rod 208 is fixedly connected to the support body 1 on the right side. A support rod 1 207 is fixedly installed on the left outer wall of the sealing cylinder 203. The bottom end of the support rod 207 is fixedly connected to the support body 1 on the left side, and a ventilation port 206 is provided on the outer wall of the sealing cylinder 203, and the ventilation port 206 is located on the left side of the piston 205. By adjusting the distance between the two support bodies 1, it is used to match the size of the incision. The left and right support bodies 1 are connected by the outer airbag 201 and the inner airbag 202 to support the incision that the support body 1 cannot support. By ventilating the inner airbag 202, the inner airbag 202 is expanded, thereby ensuring that when the distance between the support bodies 1 is adjusted, the inner airbag 202 can be extended and supported between the two support bodies 1, and by ventilating the outer airbag 201, the outer airbag 201 is The support is used to support the incision and fit it more closely. Air is ventilated from the air exchange port 206 into the sealing tube 203, so that the piston 205 pushes the piston rod 204 to move, thereby driving the support rod 208 to move, and adjusting the distance between the left and right support bodies 1. Compared with manual adjustment, this adjustment method is smoother and less likely to cause damage to the incision. A ventilation channel 6 is provided inside the support body 1, and a micro air pump 3 is fixedly installed on the top of the support body 1. The output end of the micro air pump 3 is connected to a ventilation tube 4, and the bottom end of the ventilation tube 4 is connected to the inside of the ventilation channel 6. The outer air bag 201 is connected to the ventilation channel 6 in the right support body 1 through a pipeline. The inner airbag 202 is connected with the ventilation channel 6 in the left support body 1 through a pipeline, and the outer airbag 201 and the inner airbag 202 are ventilated respectively through two different groups of micro air pumps 3, ventilation tubes 4, and ventilation channel 6, thereby realizing independent expansion and compression of the outer airbag 201 and the inner airbag 202, so that the outer airbag 201 can fit the incision more closely, and the outer wall of the sealing tube 203 is fixedly installed with a micro air pump 25, and the output end of the micro air pump 25 is connected with a ventilation tube 27, and the ventilation tube 27 is connected with the ventilation port 206, and the micro air pump 25 and the ventilation port 206 are connected through the ventilation tube 27, thereby realizing the operation of ventilating and exhausting air into the sealing tube 203;

[0026] The outer wall of the support body 1 is fixedly installed with a limit plate 8, and the lower surface of the limit plate 8 is fixedly installed with a silicone pad 9. The limit plate 8 is arranged to divide the support body 1 into two parts, the upper part is located outside the human body, and the lower part can be located inside the human body. When necessary, the limit plate 8 can be placed on the human body to support the limit plate 8, and then support the support body 1. The silicone pad 9 is arranged to prevent the limit plate 8 from sliding when placed on the human body;

[0027] The outer wall of the support body 1 is fixedly installed with a slide rail 10, and a rigid plate 11 is slidably arranged inside the slide rail 10. An elastic plate 12 is fixedly installed on the top of the rigid plate 11, and a slider is arranged at the bottom of the rigid plate 11, and the slider is slidably arranged in a slide groove on the slide rail 10. The elastic plate 12 is a bent plate, and the elastic plate 12 is separated from the rigid plate 11 toward one end of the support body 1, and the elastic plate 12 extends into the slide rail 10 toward one end of the support body 1. The slide rail 10 is provided for installing the rigid plate 11, and the rigid plate 11 can be taken out of the slide rail 10. The elastic plate 12 is pressed against the slide rail 10, so that the rigid plate 11 and the elastic plate 12 are not easy to slide, so that when the medical staff holds the rigid plate 11 to hold the entire protective device, the rigid plate 11 is not easy to slide relative to the slide rail 10. When it is necessary to adjust the position of the rigid plate 11 and the elastic plate 12 relative to the support body 1, it is only necessary to press the elastic plate 12 so that the elastic plate 12 is deformed and does not contact the slide rail 10, and the position of the rigid plate 11 can be adjusted.

[0028] A semicircular groove 14 is formed on the inner wall of the slide rail 10, and a semicircular protrusion 13 is fixedly installed on the top of the elastic plate 12, and the semicircular protrusion 13 is inserted into the semicircular groove 14. By inserting the semicircular protrusion 13 into the semicircular groove 14, the connection between the elastic plate 12 and the slide rail 10 is more stable, and the rigid plate 11 and the elastic plate 12 are further prevented from sliding relative to the slide rail 10;

[0029] The upper surface of the elastic plate 12 is provided with anti-slip stripes and anti-slip protrusions, which increase the friction force applied to medical staff when holding the rigid plate 11 and the elastic plate 12, thereby making the medical staff hold the plates more steadily.

[0030] Working principle: When in use, the two support bodies 1 are inserted into the human body through the incision, and the micro air pump 13 and micro air pump 25 on the left are turned on at the same time. The micro air pump 13 is turned on to ventilate the ventilation channel 6 through the ventilation tube 14, and then ventilate the inner air bag 202, so that the inner air bag 202 opens the left and right support bodies 1. At the same time, the micro air pump 25 ventilates the ventilation tube 27, and then ventilates the sealing tube 203, so that the piston 205 pushes the piston rod 204 to move right, and then drives the support rod 208 to move. The movement of the support rod 208 pushes the support body 1 on the right to move until the two support bodies 1 open the incision, and then the micro air pump 13 on the right is turned on to ventilate the ventilation tube 4, and the airflow enters the ventilation channel 6 from the ventilation tube 4, and then enters the outer air bag 201, so that the outer The airbag 201 expands until the outer airbag 201 fits against the incision, thereby achieving complete protection and support for the incision. Medical staff can hold the rigid plate 11 and the elastic plate 12 and then hold the slide rail 10. Because the slide rail 10 is fixedly connected to the support body 1, the support body 1 can be held. When the position of the rigid plate 11 and the elastic plate 12 needs to be adjusted, it is only necessary to press the elastic plate 12 to deform the elastic plate 12. The deformation of the elastic plate 12 drives the semicircular protrusion 13 to move, so that the semicircular protrusion 13 is disengaged from the semicircular groove 14. The rigid plate 11 and the elastic plate 12 can be rotated along the slide rail 10 until they are adjusted to a suitable position. After releasing the elastic plate 12, the elastic plate 12 recovers, driving the semicircular protrusion 13 to move and fit into the semicircular groove 14. The support body 1 can be held by holding the rigid plate 11 and the elastic plate 12.

[0031] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.
