Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intervertebral disc repositioning device. Background Technology

[0002] Lumbar disc herniation is a relatively common condition, mainly caused by varying degrees of degeneration in the different parts of the lumbar intervertebral disc (nucleus pulposus, annulus fibrosus, and cartilaginous endplates), especially the nucleus pulposus. Under the influence of external forces, the annulus fibrosus ruptures, and the nucleus pulposus protrudes (or prolapses) posteriorly or into the spinal canal, leading to irritation or compression of adjacent spinal nerve roots. This results in a series of clinical symptoms such as lower back pain, numbness and pain in one or both lower limbs. Lumbar disc herniation has the highest incidence at L4-L5 and L5-S1, accounting for approximately 95% of cases.

[0003] Current disc repositioning devices generally lack primary and secondary expansion functions, as well as lateral and anterior-posterior expansion functions. This makes it difficult to effectively push the herniated disc back into place, reduce the herniation, relieve patient pain quickly, and hinder rapid recovery. It also reduces the work efficiency of medical staff, making them less practical.

[0004] Therefore, a disc repositioning device is proposed. Summary of the Invention

It can effectively push the herniated disc in the patient, causing the herniated part to retract, quickly relieving the patient's pain, and facilitating the patient's rapid recovery. It also improves the work efficiency of medical staff and has good practicality, thus solving the problems mentioned in the background art.

The secondary dilation function includes lateral dilation and anterior-posterior dilation functions. The pressurization line is connected between the pressurization mechanism and the balloon dilation assembly; The pressurizing mechanism is used to introduce gas into the balloon dilation assembly through the pressurizing pipeline so that the balloon dilation assembly can perform primary and secondary dilation functions.

[0007] The aforementioned intervertebral disc repositioning device includes a balloon dilation assembly comprising an outer balloon, two transverse dilation balloons, two anterior-posterior dilation balloons, a first connecting tube, and a second connecting tube. The two transverse dilation balloons and the two anterior-posterior dilation balloons are all sealed and embedded in the wall of the outer balloon.

The first connecting tube connects the two transverse dilation balloons and the two transverse dilation balloons are interconnected through the first connecting tube. The second connecting tube connects the two anterior-posterior dilation balloons and the two anterior-posterior dilation balloons are interconnected through the second connecting tube.

[0008] In the aforementioned intervertebral disc repositioning device, each of the two transverse expansion balloons and the two anterior and posterior expansion balloons located inside the outer balloon has a flat surface, and each flat surface is fixedly and interconnectedly equipped with a connector, which is used to connect the first connecting tube and the second connecting tube.

[0009] In the aforementioned intervertebral disc repositioning device, the wall thickness of the two transverse expansion balloons and the two anterior and posterior expansion balloons at positions opposite to the plane is less than the wall thickness at other positions.

[0010] In the aforementioned intervertebral disc repositioning device, the pressurization pipeline includes a first hose, a second hose, and a third hose.

One end of the first hose is connected to the interior of the external balloon, one end of the second hose is connected to the side of the second connecting tube, and one end of the third hose is connected to the side of the first connecting tube.

A first one-way valve is fixedly installed on the first hose, the second hose, and the third hose, and an exhaust valve is fixedly installed on the exhaust pipe. The first one-way valve is located between the exhaust pipe and the connecting seat, and the conduction direction of the first one-way valve is oriented towards the exhaust pipe.

[0013] In the aforementioned intervertebral disc repositioning device, the pressurizing mechanism is provided in three sets, which correspond to the first hose, the second hose, and the third hose, respectively. Each set of pressurizing mechanisms includes a pressurizing ball, on the outer wall of which a connecting nozzle communicating with its interior is fixedly installed, and a second one-way valve is embedded in the side wall of the pressurizing ball. The connecting nozzle is inserted into the interior of the corresponding connecting seat, and the conduction direction of the second one-way valve is oriented towards the interior of the pressurizing ball.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-7 The present invention provides a technical solution: A disc repositioning device, such as Figure 1 As shown, it includes: balloon dilation assembly 1, pressurization tubing 2, and pressurization mechanism 3; Among them, the balloon dilation component 1 has primary dilation and secondary dilation functions, and the balloon dilation component 1 is used to reposition the herniated disc. The secondary dilation function includes lateral dilation and anterior-posterior dilation functions. Among them, the pressurization line 2 is connected between the pressurization mechanism 3 and the balloon dilation assembly 1; The pressurizing mechanism 3 is used to add gas to the balloon dilation assembly 1 through the pressurizing pipeline 2 so that the balloon dilation assembly 1 can achieve the purpose of primary dilation and secondary dilation.

[0020] The intervertebral disc repositioning device designed using the above technical solution consists of a balloon dilation component 1, a pressurization line 2, and a pressurization mechanism 3. The balloon dilation component 1 has primary and secondary dilation functions and is used to reposition the herniated disc. Primary dilation is used to roughly reposition the herniated disc, while secondary dilation is used to precisely reposition it, thus ensuring the therapeutic effect of the device on herniated discs. The lateral and anterior-posterior dilation functions can selectively further refine the repositioning of the herniated disc based on the actual condition of the patient, making the device design reasonable and practical.

[0021] The pressurization line 2 is connected between the pressurization mechanism 3 and the balloon dilation assembly 1, so that the pressurization mechanism 3 and the balloon dilation assembly 1 are interconnected through the pressurization line 2, which facilitates pressurizing the inside of the balloon dilation assembly 1 using the pressurization mechanism 3. The pressurizing mechanism 3 is used to add gas to the balloon dilation assembly 1 through the pressurizing pipeline 2 so that the balloon dilation assembly 1 can achieve primary and secondary dilation functions. The pressurizing mechanism 3 is used to add air into the balloon dilation assembly 1 so that the balloon dilation assembly 1 can achieve primary and secondary dilation.

[0022] In summary, this intervertebral disc repositioning device is reasonably designed and can effectively push the herniated disc back into place, quickly relieving the patient's pain and promoting rapid recovery. It also improves the work efficiency of medical staff and has good practicality.

[0023] Specifically, such as Figure 1-2 As shown in Figures 5-7, the balloon dilation assembly 1 consists of an outer balloon 101, two lateral dilation balloons 102, two anterior and posterior dilation balloons 103, a first connecting tube 104, and a second connecting tube 105. Specifically, the two lateral dilation balloons 102 and the two anterior and posterior dilation balloons 103 are all sealed and embedded in the wall of the outer balloon 101. The line connecting the two lateral dilation balloons 102 is perpendicular to the line connecting the two anterior and posterior dilation balloons 103. The first connecting tube 104 connects the two lateral dilation balloons 102 and the two lateral dilation balloons 102 are interconnected through the first connecting tube 104. The second connecting tube 105 connects the two anterior and posterior dilation balloons 103 and the two anterior and posterior dilation balloons 103 are interconnected through the second connecting tube 105.

[0024] The external balloon 101 expands upon inflation with air, achieving a primary expansion and roughly repositioning the herniated disc. The two transverse expansion balloons 102 and the two anterior-posterior expansion balloons 103 expand upon inflation with air, achieving a secondary expansion and fine repositioning the herniated disc. Specifically, the two transverse expansion balloons 102 expand upon inflation with air, achieving transverse expansion, and the two anterior-posterior expansion balloons 103 expand upon inflation with air, achieving anterior-posterior expansion, further repositioning the herniated disc.

[0025] Specifically, such as Figure 6 and 7 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, a plane 106 is provided at the position of the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 inside the outer balloon 101, and a connector 107 for connecting the first connecting tube 104 and the second connecting tube 105 is fixedly and connectedly installed on the plane 106.

[0026] Specifically, such as Figure 6 and 7 As shown, in order to make it easier for the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 located outside the outer balloon 101 to expand, the wall thickness of the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 at the position opposite to the plane 106 is less than the wall thickness at other positions.

[0027] Specifically, such as Figure 1-5 As shown, in order to pressurize the outer balloon 101, the two lateral expansion balloons 102, and the two anterior and posterior expansion balloons 103 respectively, the pressurization pipeline 2 is composed of a first hose 201, a second hose 202, and a third hose 203. The first hose 201, the second hose 202, and the third hose 203 are all fixedly and sealed on the wall of the outer balloon 101. One end of the first hose 201 is connected to the inside 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.

[0028] Among them, such as Figure 5As shown, in order to prevent the first hose 201, the second hose 202, and the third hose 203 from becoming tangled, 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 at the junction with the outer balloon 101 and causing air leakage, a reinforcing sleeve 204 is also fixedly provided on the outside of the junction of the first hose 201, the second hose 202, and the third hose 203 with the outer balloon 101.

[0029] Among them, such as Figure 1-5 As shown, in order to connect the first hose 201, the second hose 202, and the third hose 203 to the pressurization mechanism 3, a connecting seat 208 is fixedly installed at the other end of each of the first hose 201, the second hose 202, and the third hose 203. To allow the first hose 201, the second hose 202, and the third hose 203 to expel gas from the outer balloon 101, the two lateral expansion balloons 102, and the two anterior and posterior expansion balloons 103, a gas discharge valve is also installed on the side of each of the first hose 201, the second hose 202, and the third hose 203 near the connecting seat 208. The air pipe 206 is equipped with an exhaust valve 207. In order to prevent the gas inside the outer balloon 101, the two lateral expansion balloons 102 and the two anterior and posterior expansion balloons 103 from flowing back into the pressurization 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. The first one-way valve 205 is located between the exhaust pipe 206 and the connecting seat 208, and the conduction direction of the first one-way valve 205 is set towards the exhaust pipe 206.

[0030] Specifically, such as Figure 1-4 As shown, the pressurizing mechanism 3 is provided in three sets, which correspond to the first hose 201, the second hose 202 and the third hose 203 respectively. Each pressurizing mechanism 3 includes a pressurizing ball 301. In order to facilitate the connection between the pressurizing ball 301 and the connecting seat 208, a connecting nozzle 302 communicating with the interior of the pressurizing ball 301 is fixedly installed on the outer wall of the pressurizing ball 301, and the connecting nozzle 302 is inserted into the interior of the corresponding connecting seat 208. In order to allow outside air to enter the interior of the pressurizing ball 301, a second one-way valve 303 is also embedded in the side wall of the pressurizing ball 301, and the conduction direction of the second one-way valve 303 is set towards the interior of the pressurizing ball 301.

[0031] When the pressurizing mechanism 3 is used, pressing the pressurizing ball 301 allows outside air to enter the interior of the pressurizing ball 301 through the second one-way valve 303. Pressing the pressurizing ball 301 again allows the air inside the pressurizing ball 301 to be filled into the outer balloon 101, the two lateral expansion balloons 102, and the two anterior and posterior expansion balloons 103 through the first hose 201, the second hose 202, and the third hose 203, respectively, thereby achieving one expansion of the outer balloon 101, lateral expansion of the two lateral expansion balloons 102, and anterior and posterior expansion of the two anterior and posterior expansion balloons 103.

[0032] Working principle: When using this intervertebral disc repositioning device, an incision is made percutaneously through the sacral cleft using a scalpel. The external balloon 101, two transverse expansion balloons 102, and two anterior-posterior expansion balloons 103, all in a compressed state, are then inserted into the sacral canal through the incision until they are positioned at the site of the herniated disc. One set of pressure mechanisms 3 then applies pressure to the external balloon 101 to achieve initial expansion. Depending on the specific condition of the herniated disc, the other two sets of pressure mechanisms 3 are used to further expand the balloon. Two transverse expansion balloons 102 or two anterior-posterior expansion balloons 103 are pressurized to achieve secondary expansion. The two transverse expansion balloons 102 are inflated to push open the dural sac and vertebral root. Then, the two anterior-posterior expansion balloons 103 are inflated to push the herniated intervertebral disc back, causing the herniation to retract. Then, the gas inside the outer balloon 101, the two transverse expansion balloons 102, and the two anterior-posterior expansion balloons 103 is discharged. The outer balloon 101, the two transverse expansion balloons 102, and the two anterior-posterior expansion balloons 103 are then removed from the patient's body, and the patient's incision is treated.

[0033] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
