[0047] Specifically, such as Figure 1-2As shown in Figure 4, the balloon expansion assembly 1 is composed of an outer balloon 101, two lateral expansion balloons 102, two front and back expansion balloons 103, a first connecting tube 104 and a second connecting tube 105. Specifically, the two lateral expansion balloons 102 and the two front and back expansion balloons 103 are sealed and embedded in the wall of the outer balloon 101.

The second connecting tube 105 is connected between the two front and back expansion balloons 103, and the two front and back expansion balloons 103 are connected to each other through the second connecting tube 105.

[0048] The above-mentioned outer balloon 101 expands once when filled with air, and roughly repositions the position of the intervertebral disc protrusion. The two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 expand twice when filled with air, and finely reposition the position of the intervertebral disc protrusion. Among them, the two lateral expansion balloons 102 expand laterally when filled with air, and the two anterior and posterior expansion balloons 103 expand anterior and posterior expansion when filled with air, and further finely reposition the position of the intervertebral disc protrusion.

[0049] Specifically, such as Figure 4 and 5 As shown, in order to facilitate the connection of the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 with the first connecting tube 104 and the second connecting tube 105, planes 106 are provided at the positions of the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 located inside the outer balloon 101, and plug connectors 107 for connecting the first connecting tube 104 and the second connecting tube 105 are fixedly and communicatively installed on the planes 106.

[0050] Specifically, such as Figure 4 and 6 As shown, in order to make the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 located outside the outer balloon 101 easier to expand, the wall thickness of the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 at the positions facing away from the plane 106 is smaller than the wall thickness at other positions.

[0051] Specifically, such as Figure 2-4As shown, in order to achieve the purpose of pressurizing the outer balloon 101, the two lateral expansion balloons 102 and the two front and rear expansion balloons 103 respectively, the pressurization pipeline 2 is composed of a first hose 201, a second hose 202 and a third hose 203, wherein the first hose 201, the second hose 202 and the third hose 203 are all fixedly and sealedly installed on the wall of the outer balloon 101, one end of the first hose 201 is connected to the interior of the outer balloon 101, one end of the second hose 202 is connected to the side of the second connecting tube 105, and one end of the third hose 203 is connected to the side of the first connecting tube 104.

[0052] Among them, such as Figure 2 and 4 As shown, in order to prevent the first hose 201, the second hose 202 and the third hose 203 from being entangled, the first hose 201, the second hose 202 and the third hose 203 are fixedly connected to each other near the outer balloon 101, and the first hose 201, the second hose 202 and the third hose 203 are arranged side by side. In order to prevent the first hose 201, the second hose 202 and the third hose 203 from cracking and causing air leakage at the junction with the outer balloon 101, a reinforcement sleeve 204 is also fixedly provided on the outside of the junction with the outer balloon 101.

[0053] Among them, such as Figure 1-4 As shown in FIG7 , in order to connect the first hose 201, the second hose 202 and the third hose 203 to the pressurizing mechanism 3, a connecting seat 208 is fixedly installed at the other end of the first hose 201, the second hose 202 and the third hose 203. In order to enable the first hose 201, the second hose 202 and the third hose 203 to discharge the gas inside the outer balloon 101, the two lateral expansion balloons 102 and the two front and rear expansion balloons 103, a connecting seat 208 is connected and installed at the side of the first hose 201, the second hose 202 and the third hose 203 near the connecting seat 208. There is an exhaust pipe 206, and an exhaust valve 207 is fixedly installed on the exhaust pipe 206. In order to prevent the gas inside the outer balloon 101, the two lateral expansion balloons 102 and the two front and rear expansion balloons 103 from flowing back to the interior of the pressurizing mechanism 3 through the first hose 201, the second hose 202 and the third hose 203, a first one-way valve 205 is also fixedly installed on the first hose 201, the second hose 202 and the third hose 203, and the first one-way valve 205 is set between the exhaust pipe 206 and the connecting seat 208, and the conduction direction of the first one-way valve 205 is set toward the exhaust pipe 206.

[0054] Specifically, such as Figure 1 、 6As shown in Figures 7-10, there are three groups of pressurizing mechanisms 3, and the three groups of pressurizing mechanisms 3 are respectively arranged corresponding to the first hose 201, the second hose 202 and the third hose 203. Each group of pressurizing mechanisms 3 is composed of a piston cylinder 301, a piston 306, a piston rod 303 and a handle 304. Specifically, one end of the piston cylinder 301 is set as an open end, and the other end of the piston cylinder 301 is set as a closed end. In order to facilitate the connection between the piston cylinder 301 and the connecting seat 208, a connecting nozzle 308 is fixedly installed on the outer side of the closed end surface of the piston cylinder 301, and the connecting nozzle 308 is connected to the interior of the piston cylinder 301, and the connecting nozzle 308 is connected to the interior of the piston cylinder 301. 308 is inserted into the interior of the connecting seat 208. In order to allow air to enter the interior of the piston cylinder 301, a second one-way valve 307 is fixedly installed on the outside of the closed end face of the piston cylinder 301, and the conduction direction of the second one-way valve 307 is set toward the interior of the piston cylinder 301. The piston 306 is movably installed in the interior of the piston cylinder 301, and the piston rod 303 is fixedly installed at the end of the piston 306 facing away from the connecting nozzle 308, and the end of the piston rod 303 away from the piston 306 is extended to the outside of the open end of the piston cylinder 301, and the handle 304 is fixedly installed at the end of the piston rod 303 away from the piston 306.

[0055] When the above-mentioned pressurizing mechanism 3 is in use, the piston rod 303 is pulled by the handle 304 to drive the piston 306 to move toward the open end of the piston cylinder 301, and the outside air can enter the interior of the piston cylinder 301 through the second one-way valve 307, and then the piston rod 303 is pressed by the handle 304 to drive the piston 306 to move toward the closed end of the piston cylinder 301, and the air inside the piston cylinder 301 can be filled into the outer balloon 101, the two lateral expansion balloons 102 and the two front and rear expansion balloons 103 through the first hose 201, the second hose 202 and the third hose 203 respectively, thereby realizing one-time expansion of the outer balloon 101, lateral expansion of the two lateral expansion balloons 102 and front and rear expansion of the two front and rear expansion balloons 103.

[0056] Among them, such as Figure 8 As shown, in order to enable the piston rod 303 to move stably, an end cover 302 is screwed onto the outside of the open end of the piston cylinder 301, and a guide hole matching the piston rod 303 is reserved at the center of the end cover 302.

[0058] Working principle: When using the percutaneous sacral canal approach balloon expansion intervertebral disc reduction device, an incision is made percutaneously at the sacral fissure with a scalpel, and then the outer balloon 101 in a squeezed state, two lateral expansion balloons 102, and two anterior and posterior expansion balloons 103 are introduced into the sacral canal through the incision until the outer balloon 101, two lateral expansion balloons 102, and two anterior and posterior expansion balloons 103 are placed at the intervertebral disc herniation. Then, one set of pressurizing mechanisms 3 is used to pressurize the outer balloon 101 to achieve a first expansion. Then, according to the specific condition of the patient's intervertebral disc herniation, the other two sets of pressurizing mechanisms 3 are used to pressurize the outer balloon 101 to achieve a first expansion. The pressurizing mechanism 3 pressurizes the two lateral expansion balloons 102 or the two anterior and posterior expansion balloons 103 to achieve secondary expansion. The two lateral expansion balloons 102 are inflated to push open the dura mater and pedicles, and then the two anterior and posterior expansion balloons 103 are inflated to expand and push the protruding intervertebral disc to retract the protrusion. Then the gas inside the outer balloon 101, the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 is discharged, and then the outer balloon 101, the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 are taken out of the patient's body, and the patient's incision is treated.

The connecting nozzle (308) is connected to the connecting seat (208), the conducting direction of the second one-way valve (307) is set toward the inside of the piston cylinder (301), the piston (306) is movably installed in the interior of the piston cylinder (301), the piston rod (303) is fixedly installed at one end of the piston (306) facing away from the connecting nozzle (308), and the end of the piston rod (303) away from the piston (306) extends to the outside of the open end of the piston cylinder (301), and the handle (304) is fixedly installed at one end of the piston rod (303) away from the piston (306); The open end of the piston cylinder (301) is screwed with an end cover (302), and a guide hole matching the piston rod (303) is reserved at the center of the end cover (302). A vent hole (305) is opened on the end cover (302), and the vent hole (305) is connected to the interior of the piston cylinder (301); During use, an incision is made percutaneously at the sacral fissure using a scalpel, and then the squeezed outer balloon, two lateral expansion balloons, and two anterior and posterior expansion balloons are sent into the sacral canal channel through the incision until the outer balloon, two lateral expansion balloons, and two anterior and posterior expansion balloons are placed at the protruding intervertebral disc. Then, one of the sets of pressurizing mechanisms is used to pressurize the outer balloon to achieve a first expansion. Then, according to the specific situation of the patient's intervertebral disc herniation, the other two sets of pressurizing mechanisms are used to pressurize the two lateral expansion balloons or the two anterior and posterior expansion balloons to achieve a second expansion. The two lateral expansion balloons are inflated to push open the dura mater and pedicles, and then the two anterior and posterior expansion balloons are inflated to expand and squeeze the protruding intervertebral disc to retract the protrusion. Then, the gas inside the outer balloon, two lateral expansion balloons, and two anterior and posterior expansion balloons is discharged, and then the outer balloon, two lateral expansion balloons, and two anterior and posterior expansion balloons are taken out of the patient's body and the patient's incision is treated.
