Description

Technical Field

[0001] The invention relates to the technical field of bypass tubes, in particular to a subarachnoid space bypass tube which is convenient for accurately controlling the depth of a side hole. Background Art

[0002] The cerebrospinal fluid subarachnoid bypass catheter uses a translucent tube with both ends open. The two ends are placed in the subarachnoid space on the head and caudal sides of the syringomyelia patient. Dural puncture and catheterization require dural incision, and the dura mater is sutured after the shunt tube is inserted.

[0003] The conditions of syringomyelia patients vary. Adhesive syringomyelia may involve multiple segments. The existing drainage tubes are fixed in length and cannot be adjusted according to the patient's specific conditions, which limits their application in the treatment of multi-segment adhesive syringomyelia. Drainage tubes of inappropriate length may lead to poor surgical results and even require a second operation to replace the appropriate drainage tube. Therefore, we propose a subarachnoid bypass tube that is easy to accurately control the depth of the side hole. Summary of the invention

[0004] The present invention provides the following technical solution: a subarachnoid space bypass tube that is convenient for accurately controlling the depth of a side hole, comprising a bypass tube body, the outer wall of the bypass tube body is provided with a connecting assembly, the bottom of the bypass tube body and the connecting tube are both provided with a bullet-shaped connecting tube, the outer wall of the bullet-shaped connecting tube is provided with a plurality of side holes, and the outer wall of the bullet-shaped connecting tube is fixedly connected with a marking point on one side close to the plurality of side holes;

[0005] The connection assembly includes a connection shell located on the outer wall of the bridging tube body, the inner wall of the connection shell is provided with a medicine storage cavity, the inner wall of the medicine storage cavity is provided with a sponge, the outer wall of the sponge is fixedly connected to a connection plate, and the outer wall of the connection shell is provided with a rubber ring.

[0006] Preferably: the connecting component also includes a limiting groove, the inner wall of the limiting groove is slidably connected with a connecting block, the outer wall of the connecting shell is provided with a medicine outlet on the side close to the limiting groove, the inner wall of the limiting groove is provided with a sliding block at one end close to the medicine outlet, and the outer wall of the sliding block is fixedly connected with a connecting plate.

[0007] Preferably, the position of the medicine outlet corresponds to the position of the rubber ring.

[0008] Preferably, the length of the medicine storage cavity is greater than the length of the sponge.

[0009] Preferably, the inner wall of the connecting shell is provided with a second thread groove, and the outer wall of the bridging tube body is provided with a thread line on a side close to the connecting assembly.

[0010] Preferably, the thread line is matched with the second thread groove.

[0011] Preferably, an outer wall of the connecting tube is provided with an indwelling needle, and an inner wall of the indwelling needle is provided with a first thread groove.

[0012] Preferably, the width of the connecting pipe socket is greater than the width of the wall of the bridging pipe body.

[0013] Preferably: the porous rubber ring is made of rubber.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The bypass tube is convenient for accurately controlling the depth of the side hole. When the drainage tube needs to be extended, the connecting tube is connected to the second thread groove and then rotated so that the thread line coincides with the second thread groove. The setting of the thread line and the second thread groove increases the stability of the connecting tube. Adhesion syringomyelia may involve multiple segments. Medical staff can adjust it according to the specific situation of the patient. A drainage tube with appropriate length will effectively improve the surgical effect, and there is no need for a second operation to replace a suitable drainage tube.

[0016] 2. The bypass tube, which is convenient for accurately controlling the depth of the side hole, has a porous structure through a rubber ring. When the bypass tube body is rotated and connected to the connecting pipe socket, the agent overflows from the hole and is smeared on the tube wall along the direction of rotation. The surface of the pipeline is specially treated and anti-infection agents are smeared on the interface to prevent bacterial residues caused by operators staying at the interface for too long or being exposed to the air for too long, thereby effectively reducing the risk of postoperative infection.

[0017] 3. The bypass tube, which is convenient for accurately controlling the depth of the side holes, is designed with multiple side holes at the end of the bullet-shaped tube. This design is not only conducive to the full drainage of cerebrospinal fluid and reduces local accumulation, but also can effectively prevent the occurrence of tube blockage. The setting of the side holes increases the path of cerebrospinal fluid flow and reduces the risk of drainage failure caused by blockage of a single channel. Marking points are set on the bullet-shaped tube. This design helps doctors to accurately control the depth of the side holes during surgery, allowing medical staff to observe whether the side holes are completely immersed in the subarachnoid space, ensuring the drainage effect, while avoiding excessive penetration of the dura mater and reducing surgical risks.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-7 A subarachnoid space bypass tube that is convenient for accurately controlling the depth of the side hole, comprising a bypass tube body 1, the outer wall of the bypass tube body 1 is provided with a connecting assembly 6, the bottom of the bypass tube body 1 and the connecting tube 7 are both provided with a bullet-shaped pipe 9, the outer wall of the bullet-shaped pipe 9 is provided with a plurality of side holes 2, and the outer wall of the bullet-shaped pipe 9 is fixedly connected with a marking point 3 on one side close to the plurality of side holes 2;

[0028] The connecting assembly 6 includes a connecting shell 61 located on the outer wall of the bridging tube body 1, the inner wall of the connecting shell 61 is provided with a medicine storage cavity 66, the inner wall of the medicine storage cavity 66 is provided with a sponge 63, the outer wall of the sponge 63 is fixedly connected with a connecting plate 65, and the outer wall of the connecting shell 61 is provided with a rubber ring 64.

[0029] It should be noted that the two ends of the bottom of the bypass tube body 1 and the connecting tube 7 adopt a bullet head design. This design makes it easier for the tube to be inserted into the subarachnoid space through the dura mater, reducing the difficulty of surgical operation. The sharp part of the bullet head helps to puncture the dura mater, and the smooth transition part reduces damage to surrounding tissues, improving the safety of the operation. In order to ensure that the side hole can correctly enter the dura mater and play a drainage role, a marking point 3 is set every 10 mm on the bullet head connecting tube 9, which is helpful for helping doctors to accurately control the depth of the side hole during surgery. If the bypass tube is inserted too deep or too shallow during surgery, when multiple marking points 3 need to be set up, they can continue to be added later to reduce the damage to surrounding blood vessels, nerves and other important tissues and organs caused by the inability to observe the immersion depth. The marking points can help doctors control the depth of the bypass tube within a safe range and reduce surgery. The risk of complications can be reduced, and at the same time, the doctor can quickly and accurately determine the position of the bypass tube in the body during surgery, clearly know the gap between the current operation site and the target position, avoid surgical deviations due to position judgment errors, ensure drainage effects, and avoid excessive penetration of the dura mater, thereby reducing surgical risks. The end of the bullet-shaped tube 9 is designed with multiple side holes. This design is not only conducive to the full drainage of cerebrospinal fluid and reduces local accumulation, but the setting of the side holes increases the flow path of cerebrospinal fluid and reduces the risk of drainage failure due to blockage of a single channel. A plurality of cuttable dotted lines are provided on the bypass tube body 1. For different surgical requirements, the appropriate length can be cut according to actual needs, or cuttable dotted lines can be continued to be added to avoid waste of the entire bypass tube body 1, ensure that the length of the bypass tube body 1 can be flexibly adjusted, and ensure that the bypass tube body 1 is accurately adapted to the placement site.

[0030] See also Figure 2-5 : The connecting component 6 also includes a limiting groove 68, the inner wall of the limiting groove 68 is slidably connected to a connecting block 67, the outer wall of the connecting shell 61 is provided with a medicine outlet 611 on the side close to the limiting groove 68, the inner wall of the limiting groove 68 is provided with a sliding block 69 at one end close to the medicine outlet 611, and the outer wall of the sliding block 69 is fixedly connected to a connecting plate 610.

[0031] It should be noted that the rubber ring 64 is a disposable rubber ring. When the extension tube needs to be connected, the connecting tube 7 is rotated to connect to the inner wall of the second threaded groove 62. Since the connecting disk 65 can slide on the inner wall of the connecting shell 61, the connecting disk 65 is pushed to squeeze the sponge 63. Since the sponge 63 stored in the drug storage chamber 66 is made of sponge, the sponge 63 is initially filled with antibacterial drugs. After being squeezed, due to the characteristics of the sponge, part of the drugs are pushed out into the drug storage chamber 66. Since the outer wall of the connecting shell 61 is provided with a drug outlet 611, the antibacterial liquid enters the rubber ring 64 from the drug outlet 611, which is convenient for medical staff to apply antibacterial drugs, effectively reducing the risk of postoperative infection in patients.

[0032] At this time, after the connecting block 67 at the bottom of the rubber ring 64 slides into the limiting groove 68, since a sliding block 69 is provided at the top, the sliding block 69 is fixedly connected to the connecting plate 610, and a spring is provided inside the sliding block 69. When the rubber ring 64 slides forward to the front end to squeeze the sliding block 69, the connecting plate 610 that originally blocked the medicine outlet 611 moves forward, so that the sterilizing liquid can smoothly flow into the rubber ring 64 through the medicine outlet 611, which is convenient for medical staff to disinfect and clean the bypass tube. When the application is completed, the rubber ring 64 is slid out, and the spring in the sliding block 69 drives the sliding connecting plate 610 to automatically reset and block the medicine outlet 611, effectively preventing bacterial residues caused by the operator staying at the interface for too long or being exposed to the air for too long, and effectively reducing the risk of postoperative infection. The setting of the connecting shell 61 also ensures that the drainage tube can be adjusted according to the specific situation of the patient. Its application in the treatment of multi-segment adhesion syringomyelia can avoid poor surgical results due to drainage tubes of inappropriate length, and even the need for a second operation to replace a suitable drainage tube.

[0033] See also Figure 3-4 : The position of the medicine outlet 611 corresponds to the position of the rubber ring 64.

[0034] It should be noted that the medicine outlet 611 corresponds to the rubber ring 64, ensuring that the antibacterial medicine in the medicine storage chamber 66 can smoothly flow into the rubber ring 64 through the medicine outlet 611, making it easier for medical staff to clean the tube body and increasing the accuracy of the equipment.

[0035] See also Figure 4 : The length of the medicine storage chamber 66 is greater than the length of the sponge 63.

[0036] It should be noted that the length of the medicine storage cavity 66 is greater than the length of the sponge 63, so that when the sponge 63 is pressed, the medicine squeezed out from the inside of the sponge 63 has sufficient flow space, which effectively controls the amount of medicine flowing out and prevents leakage or liquid accumulation caused by excessive squeezed doses that may cause spraying.

[0037] See also Figure 2-5 A second thread groove 62 is formed on the inner wall of the connecting shell 61 , and a thread line 8 is formed on the outer wall of the bridging tube body 1 on a side close to the connecting component 6 .

[0038] It should be noted that, since the outer wall of the bypass tube body 1 is provided with a thread line 8, and the inner wall of the connecting shell 61 is provided with a second thread groove 62, when the connecting tube 7 is connected to the second thread groove 62, it is rotated so that the thread line 8 and the second thread groove 62 coincide with each other. The arrangement of the thread line 8 and the second thread groove 62 increases the stability of the connecting tube, and the tight fit between the threads forms an initial seal, which can meet various occasions with high requirements for sealing. The bypass tube body 1 is designed to have a diameter of 3 mm. This design not only ensures the patency of the drainage tube, but also avoids the compression and placement difficulty caused by the overly thick drainage tube on the spinal cord. By selecting a suitable tube diameter, the potential damage to the patient's spinal cord can be reduced while ensuring the drainage effect.

[0039] See also Figure 1 : The thread line 8 is adapted to the second thread groove 62.

[0040] It should be noted that since the front end of the connecting pipe 7 is provided with a thread line 8, the thread line 8 is consistent with the second thread groove 62, and the tight fit between the threads forms a sealed state, which can meet various occasions with high requirements for sealing, effectively increases the stability of the connecting pipe, prevents the risk of falling off in the later stage, and reduces the difficulty of disassembly caused by complicated connection methods.

[0041] See also Figure 6 : An indwelling needle 4 is provided on the outer wall of the connecting tube 7, and a first thread groove 5 is provided on the inner wall of the indwelling needle 4.

[0042] It should be noted that, on the one hand, the first thread groove 5 facilitates the disassembly of the indwelling needle 4 and reduces the difficulty of replacement caused by complicated connection methods. On the other hand, it increases the adaptability of the indwelling needle 4. When connecting tubes 7 of different sizes need to be connected, the setting of the first thread groove 5 facilitates the matching of the indwelling needle 4 with various sizes.

[0043] See also Figure 2-3 : The rubber ring 64 is made of rubber.

[0044] It should be noted that since the rubber ring 64 has a porous structure, when the medicine enters the rubber ring 64, the plastic rubber ring 64 is gradually filled and expanded to the gap between the connecting tube 7 and the bypass tube body 1. The small amount of medicine overflowing from the hole is evenly smeared on the tube wall through rotation, effectively reducing the risk of infection.

[0045] Working principle: the bottom ends of the bypass tube 1 and the connecting tube 7 are designed with a bullet head, which improves the safety of the operation. A marking point 3 is set every 10 mm on the bullet-head connecting tube 9, which helps the doctor to accurately control the depth of the side hole during the operation. If the bypass tube is inserted too deeply or too shallowly during the operation, when multiple marking points 3 need to be set, they can be added later to reduce the damage to the surrounding blood vessels, nerves and other important tissues and organs caused by the inability to observe the immersion depth. The marking points can help the doctor control the depth of the bypass tube within a safe range and reduce the risk of surgical complications. The end of the bullet-head connecting tube 9 is designed with multiple side holes to effectively prevent the occurrence of tube blockage. A plurality of cuttable dotted lines are provided on the bypass tube 1. For different surgical requirements, the appropriate length can be cut according to actual needs, or cuttable dotted lines can be added to avoid the waste of the entire bypass tube 1, ensure that the length of the bypass tube 1 can be flexibly adjusted, and ensure that the bypass tube 1 is accurately adapted to the placement site.

[0046] The rubber ring 64 is a disposable rubber ring. When the drainage tube needs to be extended, the connecting tube 7 is connected to the second thread groove 62 and then rotated, so that the thread line 8 coincides with the second thread groove 62. The arrangement of the thread line 8 and the second thread groove 62 increases the stability of the connecting tube. Since the connecting disk 65 can slide on the inner wall of the connecting shell 61, the connecting disk 65 is pushed to squeeze the sponge 63. Since the sponge 63 stored in the drug storage chamber 66 is made of sponge, the sponge 63 is filled with antibacterial drugs in the initial state. After being squeezed, due to the characteristics of the sponge, part of the drugs are pushed out into the drug storage chamber 66.

[0047] Since the outer wall of the connecting shell 61 is provided with a medicine outlet 611, the antibacterial liquid enters the rubber ring 64 through the medicine outlet 611, which is convenient for medical staff to apply the antibacterial medicine, and effectively reduces the risk of postoperative infection of patients. After the connecting block 67 at the bottom of the rubber ring 64 slides into the limiting groove 68, since the top is provided with a sliding block 69, the sliding block 69 is fixedly connected to the connecting plate 610, and a spring is provided inside the sliding block 69, when the rubber ring 64 slides forward to the front end to squeeze the sliding block 69, the connecting block 67 that originally blocked the medicine outlet 611 is released. The connecting plate 610 moves forward, so that the sterilizing liquid can smoothly flow into the rubber ring 64 through the medicine outlet 611, and the medicine outlet 611 corresponds to the rubber ring 64, ensuring that the antibacterial agent in the inner cavity of the medicine storage chamber 66 can smoothly flow into the rubber ring 64 through the medicine outlet 611, which is convenient for medical staff to clean the tube body and disinfect and clean the bypass tube. When the application is completed, the rubber ring 64 is slid out, and the spring in the sliding block 69 drives the sliding connecting plate 610 to automatically reset and block the medicine outlet 611;

[0048] The first thread groove 5 provided on the bypass tube body 1, on the one hand, facilitates the disassembly of the indwelling needle 4 and reduces the difficulty of replacement caused by complicated connection methods. On the other hand, it increases the adaptability of the indwelling needle 4. When connecting tubes 7 of different sizes need to be connected, the setting of the first thread groove 5 facilitates the indwelling needle 4 to match a variety of sizes.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
