Description

Technical Field

[0001] The utility model relates to the technical field of lesion lavage guide sheaths, in particular to a small ultrasonic probe guide sheath for lavage and drug injection of peripheral lung lesions. Background Art

[0002] Peripheral pulmonary lesion lavage and injection is a method of treating lung diseases, especially lesions or infections in the peripheral lungs. This method usually achieves the purpose of treatment by introducing a drug solution into the area surrounding the lungs. This treatment method may be used for a variety of lung diseases, including infections, tumors, or other lesions. In order to enable doctors to accurately locate lung lesions and surrounding anatomical structures, thereby ensuring that the drug is injected into the correct location, a small ultrasound probe guide sheath is required for peripheral pulmonary lesion lavage and injection.

[0003] During the use of a traditional small ultrasound probe guide sheath for lavage and injection of peripheral lung lesions, when connecting the spray tube to the adapter, the spray tube is directly passed through the sleeve only through the sleeve. Since the sleeve is conical, one end of the spray tube is larger than the narrowest diameter of the sleeve, so the spray tube can be stuck in the sleeve for connection and sealing.

[0004] However, it does not solve the problem that when daily injection or multiple injections are required in a short period of time, the connection strength and sealing of the sleeve will be reduced, resulting in leakage of medicine from between the sleeve and the spray pipe during injection, resulting in waste of medicine. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a small ultrasonic probe guide sheath for lavage and injection of peripheral lung lesions, aiming to improve the problem of reduced connection strength and sealing of the sleeve when daily injection or multiple injections in a short period of time are required.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a small ultrasonic probe guide sheath for lavage and injection of peripheral lung lesions, including an adapter, the adapter is provided with a sleeve, a spray pipe is slidably connected to the inside of the sleeve, a metal ring is fixedly connected to the inside of one end of the spray pipe, a support ring is fixedly connected to the inside of the sleeve, a reinforcement rope is fixedly connected to the outer wall of the support ring, a wedge-shaped clamping column is provided inside the spray pipe, one end of the wedge-shaped clamping column is fixedly connected to a fixing ring, multiple reinforcement ropes are arranged and fixedly connected in a circular array with the support ring as the center, the outer wall of the wedge-shaped clamping column is embedded in the inside of the spray pipe, and a sealing assembly is provided at one end of the adapter.

[0007] As a further description of the above technical solution:

[0008] The sealing assembly includes a sealing ring, one end of which is fixedly connected to one end of the adapter, and the other end of the sealing ring is fitted into the interior of the sleeve.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the adapter is provided with an external thread, and the interior of the sleeve is provided with an internal thread.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the adapter is rotatably connected to the inside of the sleeve, and the outer wall of the external thread is threadedly connected to the inside of the internal thread.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the adapter is fixedly connected with a fin, and one side of the fin is symmetrically arranged and fixedly connected to the outer wall of the adapter.

[0015] As a further description of the above technical solution:

[0016] The adapter is fixedly connected with convex points inside, and the convex points are arranged in a circular array with the adapter as the center and are fixedly connected inside the adapter.

[0017] As a further description of the above technical solution:

[0018] The adapter is fixedly connected with a rubber ring inside, and the rubber rings are arranged in a linear array and fixedly connected inside the adapter.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the present invention, firstly, the coordination among the support ring, the reinforcing rope, the fixing ring and the wedge-shaped clamping column is used to improve the connection strength and sealing effect between the sleeve and the spray pipe, thereby solving the problem of reduced connection strength and sealing of the sleeve when daily injection or multiple injections in a short period of time are required, and improving the connection strength of the guide sheath of the small ultrasonic probe used for lavage and injection of peripheral lung lesions.

[0021] 2. In the utility model, the connection strength between the syringe and the adapter is improved by cooperating among the adapter, fins, bumps, rubber ring and metal ring, which solves the problem that when the traditional adapter is connected to the syringe, the connection is only dependent on the friction between the rubber and the syringe, and the connection is easily unreliable after the number of plugging and unplugging increases. The service life of the small ultrasonic probe guide sheath for lavage and injection of peripheral lung lesions is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 、 Figure 3 and Figure 5 The utility model provides an embodiment: a small ultrasonic probe guide sheath for lavage and injection of medicine for peripheral lesions of the lung, comprising an adapter 1, the adapter 1 is provided with a sleeve 3, a spray pipe 4 is slidably connected inside the sleeve 3, a metal ring 12 is fixedly connected to the inside of the spray pipe 4 at one end, a support ring 6 is fixedly connected to the inside of the sleeve 3, a reinforcing rope 7 is fixedly connected to the outer wall of the support ring 6, a wedge-shaped clamping column 9 is provided inside the spray pipe 4, one end of the wedge-shaped clamping column 9 is fixedly connected to a fixing ring 8, the reinforcing rope 7 is arranged in a circular array with the support ring 6 as the center and fixedly connected to the inside of the sleeve 3, the outer wall of the wedge-shaped clamping column 9 is embedded in the inside of the spray pipe 4, a sealing assembly is provided at one end of the adapter 1, the sealing assembly comprises a sealing ring 5, one end of the sealing ring 5 is fixedly connected to one end of the adapter 1, and the other end of the sealing ring 5 is fitted into the inside of the sleeve 3;

[0031] Specifically, the length of the spray tube 4 reaches 2000mm to meet the needs of clinical operations. The outer diameter of the spray tube 4 is 1.95mm and the inner diameter is 1.85mm, which allows the insertion of a small ultrasonic probe. The connection between the spray tube 4 and the support ring 6 is called the injection end, which is the main part of the drug injection. The injection end is detachable, which makes it convenient to trim the length of the spray tube 4 with scissors according to actual needs. The diameter of the adapter 1 is 50mm, the inner diameter of the opening for connecting the syringe is 4mm, and the inner diameter of the connection with the sleeve 3 is 1.95mm. The metal ring 12 fixed inside the end of the spray tube 4 is used to position the small ultrasonic probe. When in use, first trim the injection end of the spray tube 4 to the required length, and then put the sleeve 3 on the outer wall of the spray tube 4. Next, insert the fixing ring 8 into the interior of the spray tube 4 through the wedge-shaped clamp 9. The inner diameter of the fixing ring 8 is the same as the inner diameter of the spray tube 4, both of which are 1.85mm, so as to ensure the stability of the fixation. The wedge-shaped clamping column 9 is conical and can be embedded with the inner wall of the spray pipe 4 to enhance the firmness of the connection. The sleeve 3 is then pulled out. The end of the sleeve 3 is conical, which is a clever design. One end of the sleeve 3 has a larger diameter and is provided with an internal thread 14. This will generate a certain amount of pressure on the spray pipe 4 during the pulling process, making the connection between the spray pipe 4 and the sleeve 3 tighter. The support ring 6 inside the sleeve 3 prevents the pipe from deforming and enhances the stability of the spray pipe 4. The reinforcing rope 7 is arranged in a ring with the support ring 6 as the center and fixed inside the support ring 6. This design not only limits the displacement of the support ring 6, but also prevents the sleeve 3 from being stretched under the action of external force.

[0032] Reference Figure 2 and Figure 4 , the outer wall of the adapter 1 is provided with an external thread 13, the inside of the sleeve 3 is provided with an internal thread 14, the outer wall of the adapter 1 is rotatably connected to the inside of the sleeve 3, the outer wall of the external thread 13 is threadedly connected to the inside of the internal thread 14, the outer wall of the adapter 1 is fixedly connected with a fin 2, one side of the fin 2 is symmetrically arranged and fixedly connected to the outer wall of the adapter 1, the inside of the adapter 1 is fixedly connected with a convex point 10, the convex point 10 is arranged in a circular array with the adapter 1 as the center and is fixedly connected to the inside of the adapter 1, the inside of the adapter 1 is fixedly connected with a rubber ring 11, and the rubber ring 11 is arranged in a linear array and fixedly connected to the inside of the adapter 1;

[0033] Specifically, the adapter 1 and sleeve 3 are connected via external threads 13 threaded into internal threads 14. A sealing ring 5 seals the connection between the adapter 1 and sleeve 3. Made of high-quality material, the sealing ring 5 exhibits excellent elasticity and wear resistance. When the adapter 1 and sleeve 3 are tightly connected, the sealing ring 5 effectively fills the tiny gap between them, forming a perfect seal and preventing medication leakage. When medication is required, medical personnel simply insert the syringe into the injection port of the adapter 1. This design is also ingenious. The injection port of the adapter 1 is equipped with raised bumps 10. These bumps 10 are made of rubber, which is not only soft and comfortable but also has excellent friction properties. They firmly contact the syringe connector, ensuring a secure and reliable connection between the syringe and adapter 1. Even if a certain amount of compressive force is generated during the injection process, the raised bumps 10 can deform, further increasing friction and preventing the syringe from accidentally falling off. The rubber ring 11 of the adapter 1 fits snugly between the syringe and adapter 1 to prevent medication leakage. The diameter of the rubber ring 11 is gradually reduced, and gradually becomes smaller from the adapter 1 to the external thread 13. This design can ensure that the contact between the rubber ring 11 and the syringe is closer, further improving the sealing effect.

[0034] Working principle: When using the ultrasonic small probe guide sheath for lavage and injection of peripheral lung lesions, first, the length of the spray tube 4 is 2000mm, which can be left in the airway after withdrawing from the bronchoscope. The outer diameter of the spray tube 4 is 1.95mm, and the inner diameter is 1.85mm, which can be inserted into the ultrasonic small probe. The connection between the spray tube 4 and the support ring 6 is the injection end. The injection end is detachable and convenient. The length of the adapter 1 can be trimmed with scissors as needed, and the outer diameter is thinner and can be withdrawn from the bronchoscope. The diameter of the adapter 1 is 50mm, and the adapter 1 is connected to the opening of the syringe. The inner diameter of the mouth is 4mm, the inner diameter of the connection between the adapter 1 and the sleeve 3 is 1.95mm, and the metal ring 12 fixed inside the end of the spray pipe 4 is used to position the small ultrasonic probe. During assembly, the injection end of the spray pipe 4 is trimmed to the required length, and then the sleeve 3 is placed on the outer wall of the spray pipe 4. Then, the fixing ring 8 is inserted into the interior of the spray pipe 4 through the wedge-shaped clamping column 9. The inner diameter of the fixing ring 8 is also 1.85mm. The wedge-shaped clamping column 9 is tapered, so it can be embedded in the inner wall of the spray pipe 4. Then pull out the sleeve 3. The end of the sleeve 3 is tapered. The diameter of one end of the sleeve 3 with the internal thread 14 is larger than the end, so it will squeeze the spray pipe 4. The spray pipe 4 is connected and sealed with the sleeve 3 through the cooperation of the fixing ring 8. The support ring 6 inside the sleeve 3 is used to prevent the diameter of the sleeve 3 from being deformed due to external force. The reinforcing rope 7 is arranged in a ring with the support ring 6 as the center and fixed inside the support ring 6. It is used to limit the support ring 6 while preventing the sleeve 3 from being stretched by external force. Then the adapter 1 is connected to the internal thread 14 in the sleeve 3 through the external thread 13. The adapter 1 and The sleeves 3 are sealed by a sealing ring 5. When injection is required, the syringe is inserted into the injection end of the adapter 1, so that the friction between the syringe and the adapter 1 is increased through the protrusion 10. The protrusion 10 is made of rubber and can press against the connection of the syringe. When the protrusion 10 is squeezed, it can deform to increase friction. Then the rubber ring 11 is used to seal between the syringe and the adapter 1. There are multiple rubber rings 11, and the diameter is reduced in the direction of the external thread 13 of the adapter 1 to improve the sealing with the syringe.
