Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a split balloon puncture needle device. Background Art

[0002] In the medical field, the treatment of tracheal obstruction diseases has always been an important and challenging topic. Congenital tracheal obstruction or bronchial obstruction caused by diseases seriously affects the respiratory function of patients and poses a great threat to the life and health of patients.

[0003] Traditional treatment methods for tracheal obstruction have many limitations. Some existing dilation methods, such as using rigid dilators, not only have great operation difficulty, but also are extremely easy to damage the tracheal mucosa during dilation, leading to complications such as bleeding and infection. When using related puncture needle technologies, the traditional balloon puncture needle with a structure design that the needle and the balloon advance and retreat together has obvious deficiencies. On the one hand, during the process of puncturing into the blocked trachea, since the situation ahead cannot be observed in real time, it can only blindly pass through the blocked part at one time, making the puncture process full of risks. Once the blood vessel is accidentally punctured, serious bleeding may occur, and due to the lack of effective emergency treatment measures, it is difficult to control the bleeding in a short time, posing a great threat to the life safety of patients. On the other hand, since the puncture and dilation steps cannot be flexibly adjusted according to the actual situation of tracheal obstruction, for some complex blockage situations, it is difficult to achieve an ideal treatment effect. For example, in the face of uneven blockage substances or lesions in the surrounding tissues, the traditional way of the puncture needle and the balloon advancing and retreating together cannot accurately respond, which may lead to insufficient dilation of the blocked part and affect the recovery of the patient's respiratory function. Summary of the Invention

[0004] One advantage of the present invention is that it provides a split balloon puncture needle device, and the split balloon puncture needle device realizes the separation of a needle body device and a balloon device. When piercing into a target lesion, the method of puncturing while dilating can be adopted, and the puncture process can be controlled more precisely.

[0005] Another advantage of the present invention is that it provides a split balloon puncture needle device, and the needle body device of the split balloon puncture needle device is arranged inside a pre-dilation core tube, and the balloon device is arranged outside the pre-dilation core tube, which can be used separately, avoiding damage to the patient caused by the needle body device and the balloon device passing through a target lesion at one time.

[0006] Another advantage of the present invention is that it provides a split balloon puncture needle device. During the puncture process of the split balloon puncture needle device, when the needle body device pierces through the blocked point, medical staff can withdraw the needle body device at any time to observe whether there is a blood vessel ahead, greatly reducing the risk of accidentally puncturing the blood vessel.

[0007] Another advantage of the present invention is that it provides a split balloon puncture needle device. When the blood vessel is punctured, the balloon device can be immediately inflated to squeeze the bleeding point, causing the bleeding point to coagulate briefly, controlling the bleeding in time, and improving the safety of the operation.

[0008] Another advantage of the present invention is that it provides a split balloon puncture needle device. The split balloon puncture needle device can flexibly adjust the order and degree of puncture and balloon dilation.

[0037] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0039] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of the element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0040] Refer to Fig. Figure 1 to Fig. Figure 7 As shown, a split balloon puncture needle device 1 according to a preferred embodiment of the present invention is schematically shown. The split balloon puncture needle device 1 is applied to the treatment and diagnosis of tracheal obstruction-related diseases. Specifically, the split balloon puncture needle device 1 can effectively widen the blocked tracheal passage, improve the ventilation function of the patient, and relieve symptoms such as dyspnea and wheezing caused by tracheal obstruction.

[0041] For ease of description, in this embodiment, one end of the split balloon puncture needle device 1 during use when placed at a target lesion is defined as the front end of the split balloon puncture needle device 1, and the end opposite to the front end of the split balloon puncture needle device 1 is defined as the rear end of the split balloon puncture needle device 1.

[0042] Figure 1 It is a schematic diagram of the overall structure of the split balloon puncture needle device 1 according to the first preferred embodiment of the present invention. In this embodiment, the split balloon puncture needle device 1 includes a needle body device 10, a balloon device 20, a pre-expansion core tube 30, and a handle device 40. The pre-expansion core tube 30 is installed inside the handle device 40. The rear ends of the needle body device 10 and the pre-expansion core tube 30 are both connected to the handle device 40. The needle body device 10 is disposed inside the pre-expansion core tube 30, and the balloon device 20 is disposed outside the pre-expansion core tube 30. The handle device 40 is adapted to control the pre-expansion core tube 30 to extend forward, so that the needle body device 10 and the balloon device 20 move forward and perform puncture and expansion operations on the target lesion. Based on this, that is to say, the needle body device 10 and the balloon device 20 can be used separately. When piercing the target lesion, a method of puncturing and expanding simultaneously can be adopted, which can more precisely control the puncture process and avoid the needle body device 10 and the balloon device 20 passing through a target lesion at one time and causing damage to the patient.

[0043] The split balloon puncture needle device 1 further includes an outer tube device 50. The rear end of the outer tube device 50 is fixed to the handle device 40 and sleeved outside the balloon device 20. In other words, the front end of the outer tube device 50 extends towards the pre-expansion core tube 30 to enclose the balloon device 20 inside. The pre-expansion core tube 30 is adapted to drive the balloon device 20 to extend out of the outer tube device 50 under the drive of the handle device 40 so that the balloon device 20 can be inflated.

[0044] Specifically, the handle device 40 includes a first handle 41 and a second handle 42. The second handle 42 is sleeved on the rear end of the first handle 41. The second handle 42 is adapted to slide relative to the first handle 41. The rear ends of the needle device 10 and the pre-expansion core tube 30 are both connected to the second handle 42. The rear end of the outer tube device 50 is fixed to the first handle 41, and the outer tube device 50 and the first handle 41 maintain a relatively stationary state. Based on this, when the second handle 42 slides forward relative to the first handle 41, the second handle 42 is adapted to control the pre-expansion core tube 30 to extend forward, so that the needle device 10 and the balloon device 20 are adapted to perform a puncture operation and an expansion operation on the target lesion.

[0045] It is worth noting that based on the above description, in this embodiment, it is defined that the needle device 10 has a puncture state, a standby state, and a withdrawal state. The puncture state of the needle device 10 is defined as the state in which, under the drive of the second handle 42, the needle device 10 moves toward the target lesion and performs a puncture operation on the target lesion; the standby state of the needle device 10 is defined as the state in which the second handle 42 remains stationary, the second handle 42 is away from the first handle 41, and the needle device 10 also remains stationary; the withdrawal state of the needle device 10 is defined as the state in which the needle device 10 is withdrawn from the pre-expansion core tube 30. That is, as Figure 8 shown, it is a schematic structural view of the needle device 10 of the split balloon puncture needle device 1 according to an embodiment of the present invention in the withdrawn state.

[0046] Even more worth mentioning is that based on the above description, as Figure 3 shown, it is a schematic overall structural view of the balloon device 20 of the split balloon puncture needle device 1 according to an embodiment of the present invention in the contracted state. As Figure 5 shown, it is a schematic overall structural view of the balloon device 20 of the split balloon puncture needle device 1 according to an embodiment of the present invention in the state to be inflated. As Figure 6As shown, it is a schematic diagram of the overall structure of the balloon device 20 of the split balloon puncture needle device 1 according to an embodiment of the present invention in a state to be inflated. In this embodiment, it is defined that the balloon device 20 has a contracted state, a state to be inflated, and an inflated state. Among them, the contracted state of the balloon device 20 is defined as a state in which the second handle 42 remains stationary, the second handle 42 is far from the first handle 41, and the balloon device 20 is wrapped inside the outer tube device 50; the state to be inflated of the balloon device 20 is defined as a state in which, under the drive of the second handle 42, the pre-expansion core tube 30 drives the balloon device 20 to move towards the target lesion, extends out of the outer tube device 50 but has not been inflated or filled with liquid; the inflated state of the balloon device 20 is defined as a state in which, under the drive of the second handle 42, the pre-expansion core tube 30 drives the balloon device 20 to move towards the target lesion and has been inflated or filled with liquid. Among them, when the balloon device 20 is in the inflated state, the balloon device 20 extends out of the outer tube device 50, that is to say, the outer tube device 50 does not restrict the balloon device 20 from expanding.

[0047] Specifically, referring to Figure 2 As shown, it is a cross-sectional view of the split balloon puncture needle device 1 according to an embodiment of the present invention. The pre-expansion core tube 30 includes a core tube main body portion 31, a tapered portion 32, and a rear end fixing portion 33. The tapered portion 32 is integrally connected to the front end of the core tube main body portion 31, and the tapered portion 32 is arranged to taper and extend towards its front end, that is to say, the front end diameter of the tapered portion 32 is smaller than the rear end diameter of the tapered portion 32. The tapered portion 32 is used for pre-expansion operation on the target lesion. The rear end fixing portion 33 is connected to the rear end of the core tube main body portion 31, and the rear end fixing portion 33 is fixed to the second handle 42. In other words, the front end of the core tube main body portion 31 is integrally connected to the tapered portion 32, and the rear end of the core tube main body portion 31 is fixed to the second handle 42 through the rear end fixing portion 33. When the second handle 42 moves forward from the first handle 41, it is adapted to drive the pre-expansion core tube 30 to extend forward, and further drive the needle body device 10 and the balloon device 20 to move forward. At this time, the needle body device 10 is in the puncture state, and the balloon device 20 is in the state to be inflated. The needle body device 10 can perform a puncture operation on the target lesion, and the tapered portion 32 of the pre-expansion core tube 30 is adapted to perform a pre-expansion operation on the target lesion. Then, through the inflation or filling of the balloon device 20 with liquid, the balloon device 20 is inflated to further expand the target lesion.

[0048] In this embodiment, the diameter of the rear end of the tapered portion 32 is set to be larger than the diameter of the core tube main body portion 31, and further, the balloon device 20 is disposed outside the core tube main body portion 31 to perform a dilation operation on the target lesion site.

[0049] More specifically, the pre-dilation core tube 30 further has a needle body channel 34 that extends backward from the front end of the tapered portion 32 to penetrate through the tapered portion 32 and the core tube main body portion 31, and the needle device 10 is detachably installed in the needle body channel 34 of the pre-dilation core tube 30. Therefore, the needle device 10 and the balloon device 20 are not integrally provided, and the two can be used separately, avoiding damage to the patient caused by the needle device 10 and the balloon device 20 passing through the target lesion site at one time.

[0050] Reference Figure 1 As shown, the needle device 10 includes a needle tip portion 11, a needle body portion 12, and a fixed mounting end 13. The needle tip portion 11 is integrally formed on the needle body portion 12, and the needle tip portion 11 is adapted to protrude from the needle body channel 34 of the pre-dilation core tube 30 to perform a puncture operation on the target lesion. The fixed mounting end 13 is detachably installed at the rear end of the second handle 42, and the rear end of the needle body portion 10 is connected to the fixed mounting end 13. That is to say, when the fixed mounting end 13 is fixed to the second handle 42, the needle body portion 12 and the needle tip portion 11 are fixed in the needle body channel 34 of the pre-dilation core tube 30 and the needle tip portion 11 protrudes from the needle body channel 34 of the pre-dilation core tube 30. In addition, the relative positions of the needle tip portion 11, the needle body portion 12 and the pre-dilation core tube 30 remain unchanged. When the fixed mounting end 13 is detached from the second handle 42, the needle body portion 12 is separated from the fixed mounting end 13, and the medical staff can withdraw the needle device 10 through the needle body portion 12, and then the needle device 10 is in the withdrawn state. Based on this, during the puncture process of the split balloon puncture needle device 1, when the needle device 10 pierces the blockage point, that is, the target lesion site, the medical staff can withdraw the needle device 10 at any time to observe whether there is a blood vessel in front, greatly reducing the risk of accidentally puncturing a blood vessel. Even when a blood vessel is punctured, the balloon device 20 can be immediately inflated to squeeze the bleeding point, causing the bleeding point to coagulate briefly and controlling the bleeding in time, improving the safety of the operation.

[0051] It is worth mentioning that the split balloon puncture needle device 1 enables the separation of the needle body device 10 and the balloon device 20, and can flexibly adjust the sequence and degree of the puncture operation of the needle body device 10 and the dilation operation of the balloon device 20. For complex tracheal obstruction cases, it can provide a more personalized treatment plan, improve the treatment effect, and meet the treatment needs of different patients. That is to say, when the needle body device 10 pierces the obstruction point, that is, the target lesion, the medical staff can withdraw the needle body device 10 at any time, first use the balloon device 20 for dilation operation, and when piercing a target lesion, the method of piercing while dilating can be adopted, which can more accurately control the puncture process. Moreover, it can better adapt to different obstruction situations, effectively avoid excessive damage to the tracheal wall, and improve the safety and effectiveness of the treatment.

[0052] In this embodiment, the balloon device 20 includes a balloon portion 21, a balloon connection portion 22, an inflation interface 24 and an inflation channel 23. The balloon portion 21 and the balloon connection portion 22 are arranged outside the core tube main body portion 31 of the pre-expansion core tube 30, and the balloon portion 21 is connected to the balloon connection portion 22. The inflation channel 23 is located in the balloon connection portion 22. Specifically, the inflation channel 23 is located between the balloon connection portion 22 and the core tube main body portion 31 of the pre-expansion core tube 30, and the inflation interface 24 is arranged on the second handle 42 and communicates with the inflation channel 23. That is to say, a liquid or gas is adapted to enter the inflation channel 23 through the inflation interface 24 and finally reach the balloon portion 21 to cause the balloon portion 21 to expand, so as to perform a dilation operation on the target lesion. Or when a blood vessel is pierced, the inflated balloon portion 21 can squeeze the bleeding point, cause the bleeding point to coagulate briefly, control the bleeding in time, and improve the safety of the operation.

[0053] It is worth mentioning that the split balloon puncture needle device 1 avoids excessive pulling and squeezing of surrounding healthy tissues during the dilation process. Since the needle body device 10 and the balloon device 20 can be operated separately, when the balloon device 20 dilates, the action range can be accurately controlled, and only the obstruction site and its surrounding narrow areas are moderately dilated. Moreover, the split balloon puncture needle device 1 is easy to operate, reduces the excessive requirements for the operation skills of medical staff, and the operation is more controllable.

[0054] In this embodiment, the first handle 41 includes a first gripping portion 411, an inner handle tube 412, and has a first installation channel 416. The gripping portion 411 is sleeved outside the outer handle tube 412 for medical staff to grip. The first installation channel 416 is located inside the inner handle tube 412. Specifically, the first installation channel 416 extends backward from the front end of the inner handle tube 412 to penetrate the inner handle tube 412, and the pre-expansion core tube 30 is installed in the first installation channel 416.

[0055] The first handle 41 further includes a limiting portion 413, a front interface 414, and a rear cover 415. The limiting portion 413 is disposed outside the outer handle tube 412 and abuts against the first gripping portion 411. The second handle 42 is adapted to slide forward and will be restricted by the limiting portion 413 after reaching a predetermined position. The front interface 414 is disposed at the front end of the inner handle tube 412 and is wrapped inside the first gripping portion 411. The rear cover 415 is disposed at the rear end of the inner handle tube 412. A through hole is provided in both the front interface 414 and the rear cover 415, and the through hole communicates with the first installation channel 416. The rear end of the pre-expansion core tube 30 is adapted to be connected and fixed to the second handle 42 through the through hole and the first installation channel 416.

[0056] The second handle 42 includes a second gripping portion 421 and has a second installation channel 422. The second installation channel 422 is located inside the second gripping portion 421. Specifically, the second installation channel 422 extends recessedly backward from the front end of the second gripping portion 421 to install the inner handle tube 412 of the first handle 41. The second installation channel 422 communicates with the first installation channel 416, and the diameter of the second installation channel 422 is larger than the diameter of the first installation channel 416 to facilitate the sliding of the second gripping portion 421 of the second handle 42 along the inner handle tube 412 of the first handle 41. That is to say, the second gripping portion 421 of the second handle 42 is adapted to slide along the inner handle tube 412 of the first handle 41. Since the rear end of the pre-expansion core tube 30 is connected to the second gripping portion 421, based on this, when the second gripping portion 421 of the second handle 42 slides along the inner handle tube 412 of the first handle 41, it drives the pre-expansion core tube 30 to slide, and further drives the needle device 10 and the balloon device 20 respectively disposed inside and outside the pre-expansion core tube 30 to slide, so as to perform a puncture operation and a dilation operation on the target lesion.

[0057] The split balloon puncture needle device 1 further includes a radiopaque ring 60, which is disposed on the pre-dilation core tube 30. Specifically, the radiopaque ring 60 is disposed outside the core tube main body 31 of the pre-dilation core tube 30 and is arranged between the tapered portion 32 and the balloon portion 21 of the balloon device 20. The radiopaque ring 60 helps to improve the accuracy of puncture. Especially for some targets with deeper positions and complex surrounding structures, the radiopaque ring 60 can provide more accurate guidance for medical staff, reduce puncture errors, help medical staff understand the depth of the split balloon puncture needle device 1 entering the human body, ensure that the split balloon puncture needle device 1 operates within a safe and effective range, and avoid affecting the diagnostic or therapeutic effect due to too deep or too shallow puncture.

[0058] The following exemplarily introduces the method suitable for the split balloon puncture needle device 1: First, before use, there is a predetermined distance between the second handle 42 and the first handle 41. The medical staff moves the second handle 42 through the soil hole so that the second handle 42 moves towards the first handle 41, driving the pre-dilation core tube 30 to move forward, and then driving the needle device 10 and the balloon device 20 respectively disposed inside and outside the pre-dilation core tube 30 to slide to the target lesion. At this time, the needle device 10 is in the puncture state, and the balloon device 20 is not restricted by the outer tube device 50 and is in a state of waiting to be inflated. The needle device 10 is suitable for performing a puncture operation on the target arrangement, and the balloon device 20 is suitable for performing a dilation operation on the target arrangement. In addition, the medical staff can also make the needle device 10 in a withdrawn state by disassembling the fixed mounting end 13 of the needle device 10. The medical staff can withdraw the needle device 10 at any time to observe whether there is a blood vessel in front, greatly reducing the risk of accidental puncture of the blood vessel.

[0059] In summary, the split balloon puncture needle device 1 is applied to the treatment and diagnosis processes of tracheal obstruction-related diseases. Specifically, the split balloon puncture needle device 1 can effectively widen the blocked tracheal passage, improve the patient's ventilation function, and relieve symptoms such as dyspnea and wheezing caused by tracheal obstruction. The needle body device 10 and the balloon device 20 can be used separately. When piercing the target lesion, the method of puncturing and dilating simultaneously can be adopted, which can more precisely control the puncture process and avoid damaging the patient when the needle body device 10 and the balloon device 20 pass through a target lesion at one time. During the puncture process of the split balloon puncture needle device 1, when the needle body device 10 pierces the blocked point, that is, the target lesion, medical staff can withdraw the needle body device 10 at any time to observe whether there is a blood vessel in front, greatly reducing the risk of accidentally puncturing a blood vessel. Even when a blood vessel is punctured, the balloon device 20 can be immediately inflated to squeeze the bleeding point, causing the bleeding point to coagulate briefly and timely controlling the bleeding, improving the safety of the operation.

The object of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been demonstrated and explained in the embodiments.
