Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly relates to an exhaust structure and a stapler system. Background Art

[0002] The foramen ovale is a physiological passage in the interatrial septum of the heart during the embryonic period. After birth, with the increase in left atrial pressure and the decrease in pulmonary artery resistance, the primary septum and the secondary septum of the interatrial septum approach and fuse with each other. In most people, the foramen ovale closes spontaneously within one year after birth. Those who fail to close form a potential passage in the middle of the interatrial septum, namely patent foramen ovale (PFO).

[0003] When there is a patent foramen ovale (PFO), a PFO closure surgery is required. Currently, a stapler can be used to treat PFO by suture. When using a stapler for PFO closure surgery, it is necessary to ensure that there is no gas in the tube body of the stapler. Otherwise, after the stapler enters the human body, the gas in the stapler tube body is likely to generate air embolism and embolism in the human body, ultimately resulting in surgical failure or causing new diseases.

[0033] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0034] The serial numbers assigned to the components in this document, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0035] An exhaust structure and a stapler system are provided in an embodiment of the present application. The stapler system includes a needle ejecting device, a suture control device, and the following exhaust structure. The needle ejecting device includes a main body tube 40, an inner tube 50, and a puncture needle 60. The needle ejecting device is used to push out or retract the puncture needle 60. The suture control device is used to push or retract the suture. The exhaust structure is used to exhaust the tube bodies in the stapler system. The tube bodies in the stapler system include the main body tube 40, the inner tube 50, and a plurality of puncture needles 60. As Figure 1 shown, the main body tube 40 includes a first chamber 41 and a plurality of second chambers 42. The plurality of second chambers 42 are spaced apart around the axis of the first chamber 41. The inner tube 50 is movably sleeved in the first chamber 41, and the puncture needle 60 is movably sleeved in the second chamber 42.

[0036] The application mode of the stapler system in the embodiment of the present application is described by taking its application to patent foramen ovale closure as an example. It should be noted that the stapler system in the present application can be used not only for patent foramen ovale closure, but also for atrial septal defect suture surgery, ventricular septal defect suture surgery, mitral valve suture surgery, arteriovenous suture surgery, etc.

[0037] As Figures 2 - 11 shown, the exhaust structure includes a first exhaust assembly 10 and a second exhaust assembly 20.

[0038] The first exhaust assembly 10 includes an exhaust pipe 11, a first knob 12, a cap 13, and a first sealing ring 14. One end of the exhaust pipe 11 is detachably sleeved with the first knob 12, and the other end of the exhaust pipe 11 is detachably sleeved with the cap 13. The first sealing ring 14 is located inside the exhaust pipe 11 and contacts the first knob 12. A liquid injection port is provided on the cap 13 or the exhaust pipe 11 on the side of the first sealing ring 14 away from the first knob 12. A rotation hole 12a is provided on the first knob 12 for the main pipe 40 to pass through or penetrate the exhaust pipe 11. The first knob 12 is further configured to squeeze the first sealing ring 14 so that the first sealing ring 14 is tightly fitted with the outer periphery (i.e., the outer side wall) of the main pipe 40 in the radial direction. Alternatively, the first knob 12 is further configured to move away from the first sealing ring 14 so that the first sealing ring 14 and the outer periphery of the main pipe 40 are spaced apart in the radial direction.

[0039] The second exhaust assembly 20 includes a first pipe body 21, a second sealing ring, and a second knob 22. One end of the first pipe body 21 is hermetically and fixedly sleeved with the end of the main pipe 40 away from the first exhaust assembly 10. The other end of the first pipe body 21 is sleeved with the second knob 22. The second sealing ring is located inside the first pipe body 21 and contacts the second knob 22. The second knob 22 is configured to allow the inner pipe 50 to pass through and be placed inside the main pipe 40. The second knob 22 is further configured to squeeze the second sealing ring so that the second sealing ring is tightly fitted with the outer periphery of the inner pipe 50 in the radial direction. Alternatively, the second knob 22 is further configured to move away from the second sealing ring so that the second sealing ring and the outer periphery of the main pipe 40 are spaced apart in the radial direction.

[0040] When exhaust is required, the cap 13 is connected to the exhaust pipe 11, and liquid is injected into the exhaust pipe 11 through the liquid injection port. The first sealing ring 14 is tightly fitted with the main pipe 40, and the second sealing ring and the inner pipe 50 are spaced apart.

[0041] In the exhaust structure in the embodiments of the present application, through the cooperation of the first exhaust assembly 10 and the second exhaust assembly 20, when exhaust is required, the screw cap 13 is connected to the exhaust pipe 11, the first sealing ring 14 is tightly fitted with the main body pipe 40, and the second sealing ring and the inner pipe 50 are spaced apart. Liquid is injected into the exhaust pipe 11 through the liquid injection port. The liquid in the exhaust pipe 11 will flow into and fill the first chamber 41 and the second chamber 42 of the main body pipe 40, realizing the exhaust of the first chamber 41 and the second chamber 42 in the main body pipe 40, that is, exhausting the chamber of the main body pipe 40 that houses the inner pipe 50 and the chamber of the main body pipe 40 that houses the puncture needle 60. At the same time, the liquid in the first chamber 41 can also flow into and fill the inner pipe 50, realizing the exhaust of the inner pipe 50, and the liquid in the second chamber 42 can also flow into and fill the space in the puncture needle 60, realizing the exhaust of the puncture needle 60. That is, through the designed exhaust structure, multiple pipe bodies in the stapler system can be exhausted simultaneously, with a relatively high exhaust efficiency. When exhausting, in order to facilitate the exhaust of the entire first chamber 41 of the main body pipe 40 that houses the inner pipe 50, the second sealing ring in the second exhaust assembly 20 and the inner pipe 50 are spaced apart, so that the entire first chamber 41 of the main body pipe 40 is filled with liquid, and liquid can flow out at the second knob 22 to ensure the exhaust effect. After the exhaust is completed, the second sealing ring and the outer periphery of the inner pipe 50 are tightly fitted to prevent external gas from entering the first chamber 41 to further maintain the exhaust effect.

[0042] As Figure 3 shown, the exhaust pipe 11 is provided with an axially connected first channel 11a and a second channel 11b. The inner diameter of the second channel 11b is larger than the inner diameter of the first channel 11a, and the inner diameter of the first channel 11a is larger than the outer diameter of the main body pipe 40. The second channel 11b is provided with an internal thread, and one end of the first knob 12 facing the exhaust pipe 11 is provided with an external thread. The first knob 12 is threadedly connected to the exhaust pipe 11. The first sealing ring 14 is located inside the second channel 11b near the first channel 11a. By screwing the first knob 12 into or out of the second channel 11b, the deformation amount of the first sealing ring 14 is changed. Through the cooperation of the first knob 12 and the first sealing ring 14, both the connection sealing performance between the first sealing ring 14 and the outer side wall of the main body pipe 40 can be guaranteed, and the exhaust pipe 11 can be conveniently moved at different positions of the main body pipe 40.

[0043] The first sealing ring 14 is, for example, a silicone sealing ring. When the first knob 12 is screwed into the exhaust pipe 11, the first sealing ring 14 is squeezed, causing the first sealing ring 14 to deform. When the first knob 12 is screwed out, that is, away from the first sealing ring 14, the first sealing ring 14 restores its deformation through its own elasticity.

[0044] The structure of the second sealing ring (not shown) is similar to that of the first sealing ring 14. The assembly method of the second sealing ring in the first pipe body 21 is similar to the assembly method of the first sealing ring 14 in the exhaust pipe 11. Therefore, the specific position of the second sealing ring is not shown. Specifically, the second knob 22 is threadedly connected to the first pipe body 21. For example, the end of the second knob 22 close to the first pipe body 21 is provided with an external thread, and the inner part of the end of the first pipe body 21 close to the second knob 22 is provided with an internal thread. By cooperating the second knob 22 with the second sealing ring, the connection tightness between the second sealing ring and the outer side wall of the inner pipe 50 can be ensured, and the inner pipe 50 can be conveniently moved to different positions in the main pipe 40.

[0045] As Figures 2 - 3 shown, specifically, a liquid injection pipe 11c is provided on the side wall of the exhaust pipe 11 provided with the first channel 11a. A liquid injection channel 11d is formed in the liquid injection pipe 11c, and the liquid injection channel 11d is communicated with the first channel 11a. Since the inner diameter of the first channel 11a is larger than the outer diameter of the main pipe 40, that is, there is a gap between the cavity wall of the first channel 11a and the outer side wall of the main pipe 40. When exhaust is required, by injecting liquid (such as heparin water) into the liquid injection pipe 11c, the liquid can flow along the gap between the cavity wall of the first channel 11a and the outer side wall of the main pipe 40 to the end of the first channel 11a far from the first knob 12, and then continue to flow into the first chamber 41, the second chamber 42, the inner pipe 50 and the puncture needle 60 for exhaust operation.

[0046] As Figures 2 - 3 shown, specifically, the end of the exhaust pipe 11 close to the cap 13 is provided with an external thread, and the end of the cap 13 close to the exhaust pipe 11 is provided with an internal thread. The cap 13 is threadedly connected to the exhaust pipe 11. Preferably, the first exhaust assembly 10 further includes a sealing ring 15. The sealing ring 15 is located at the end of the external thread far from the cap 13. The sealing ring 15 is sleeved on the outer side wall of the exhaust pipe 11. The sealing ring 15 is used to ensure the tightness at the connection between the cap 13 and the exhaust pipe 11. An annular groove 11e is formed on the outer side wall of the exhaust pipe 11. The sealing ring 15 is sleeved in the annular groove 11e. The annular groove 11e facilitates the snap - fit assembly of the sealing ring 15. When the cap 13 is threadedly connected to the exhaust pipe 11, the two axial ends of the sealing ring 15 are respectively abutted against the end of the cap 13 and the outer wall of the exhaust pipe 11 to ensure the airtightness at the connection between the cap 13 and the exhaust pipe 11, thereby ensuring the exhaust effect. The sealing ring 15 can be made of an elastic material. For example, the sealing ring 15 is a silica gel ring.

[0047] As Figure 4 、 Figure 6 and Figure 8As shown, the exhaust structure further includes a third exhaust assembly 30. The third exhaust assembly 30 includes a third pipe body 31, a third sealing ring (not shown), and a third knob 32. One end of the third pipe body 31 is hermetically and fixedly sleeved with the end of the inner pipe 50 away from the first exhaust assembly 10. The other end of the third pipe body 31 is sleeved with the third knob 32. For example, the third pipe body 31 and the third knob 32 are threadedly connected. The third sealing ring is located inside the third pipe body 31 and contacts the third knob 32.

[0048] The third knob 32 is used for the capture net 70 and the push rod 80 connected to the capture net 70 to pass through and be placed inside the inner pipe 50. The third sealing ring has a first state, a second state, and a third state. In the first state, the third sealing ring is tightly fitted with the outer periphery of the push rod 80 in the radial direction. In the second state, the third sealing ring and the outer periphery of the push rod 80 are spaced apart in the radial direction. In the third state, the inner diameter of the third sealing ring becomes zero. The third knob 32 is also used to move relative to the third sealing ring to switch different states of the third sealing ring. The third sealing ring is also, for example, a silica gel sealing ring. By screwing the third knob 32 into or out of the third pipe body 31, the deformation amount of the third sealing ring is changed. When the capture net 70 and the push rod 80 are sleeved inside the inner pipe 50 and the inner pipe 50 is exhausted, the third sealing ring is in the second state to facilitate exhausting the channel or space inside the inner pipe 50. After the inner pipe 50 finishes exhausting, the third sealing ring can be in the first state to facilitate maintaining the exhaust effect and preventing external gas from entering the inner pipe 50. When there is no capture net 70 and push rod 80 sleeved inside the inner pipe 50, after the inner pipe 50 finishes exhausting, the third sealing ring is in the third state to prevent external gas from entering the inner pipe 50.

[0049] As Figure 7 shown, when using the stapler system, the inner pipe 50 needs to extend out of the main pipe 40 for a certain distance to facilitate the inner pipe 50 passing through the foramen ovale to reach the left atrium.

[0050] As Figure 8 shown, the ends of the capture net 70 and the push rod 80 close to each other are connected. The capture net 70 and the push rod 80 can be placed inside the inner pipe 50. The inner pipe 50 provides a moving channel for the capture net 70. By the push rod 80, it is convenient to apply force to push the capture net 70 to move inside the inner pipe 50 to facilitate the capture net 70 reaching the left atrium. Figure 8The capture net 70 in [description] is in the deployed state. The capture net 70 can be compressed, for example, into a thin strip shape, so as to be easily stored in the inner tube 50 and move within the inner tube 50. The capture net 70 is made of an elastic material, so that after the push rod 80 pushes the capture net 70 out of the inner tube 50 and reaches the left atrium, the capture net 70 changes to the deployed state. The capture net 70 in the deployed state can accommodate the puncture needle 60. The capture net 70 is used to capture the suture. After the capture net 70 grabs the suture, the push rod 80 pulls the capture net 70 back into the inner tube 50. At this time, the capture net 70 becomes a thin strip. Continuing to pull the push rod 80 can pull the capture net 70 out of the inner tube 50, and the suture is also pulled out of the body by the capture net 70.

[0051] Taking the exhaust structure including the first exhaust component 10, the second exhaust component 20, and the third exhaust component 30 as an example, the principle of the exhaust structure for exhausting the tube body in the stapler system is described as follows:

[0052] As Figure 4 shown, before exhausting, the rotary cap 13 and the exhaust pipe 11 are in a separated state. The exhaust pipe 11 is sleeved on the main body pipe 40. The first sealing ring 14 and the outer peripheral diameter of the main body pipe 40 can be distributed at intervals through the first knob 12, so as to move the exhaust pipe 11 to the side close to the housing 90 of the stapler system. Operate the second knob 22 to make the second sealing ring and the outer peripheral diameter of the inner tube 50 fit tightly, so as to fix the inner tube 50 through the second sealing ring. Operate the third knob 32 to make the third sealing ring and the outer peripheral diameter of the push rod 80 fit tightly, so as to fix the push rod 80 through the third sealing ring.

[0053] As Figure 9 shown, when exhausting is required, operate the first knob 12 to make the first sealing ring 14 and the outer peripheral diameter of the main body pipe 40 distributed at intervals, and move the exhaust pipe 11 to the end of the main body pipe 40 away from the housing 90 in the stapler system. At this time, the rotary cap 13 and the exhaust pipe 11 are threadedly connected. The end of the main body pipe 40 (i.e., Figure 9 the leftmost end of the main body pipe 40 in [description]) can be placed inside the exhaust pipe 11 or inside the rotary cap 13 outside the exhaust pipe 11. Operate the second knob 22 to make the second sealing ring and the outer peripheral diameter of the inner tube 50 distributed at intervals. Operate the third knob 32 to make the third sealing ring and the outer peripheral diameter of the push rod 80 distributed at intervals. Inject heparin water into the injection channel 11d through the injection tube 11c. The heparin water flows into the rotary cap 13 along the gap between the first channel 11a and the outer side wall of the main body pipe 40, and then flows into the first chamber 41, the second chamber 42, the inner tube 50, and the puncture needle 60 through the end of the exhaust pipe 11 close to the rotary cap 13. Figure 9In the figure, the first window A corresponds to the port where the puncture needle 60 penetrates the main tube 40, and the second window B corresponds to the end of the puncture needle 60 away from the port. When liquid is seen flowing out at the first window A, it means that the second chamber 42 accommodating the puncture needle 60 is successfully vented, and when liquid is seen flowing out at the second window B, it means that the puncture needle 60 is successfully vented. When liquid is seen flowing out at the second knob 22, it means that the first chamber 41 accommodating the inner tube 50 is successfully vented. When liquid is seen flowing out at the third knob 32, it means that the inner tube 50 is successfully vented. The designed exhaust structure can simultaneously exhaust multiple tubes and chambers, has high exhaust efficiency, shortens the operation time, improves the success rate of the operation, and is easy to operate. After the exhaust is completed, the exhaust structure can be restored to the state before the exhaust. It should be noted that in order to ensure the exhaust effect, during exhaust, the following can be done: Figure 9 The structure of the device shown is low on the left and high on the right, ensuring that the heparin water can flow from the low place to the high place, thereby ensuring the exhaust effect.

[0054] like Figure 5 As shown, the second exhaust assembly 20 further includes a first valve 24, a second tube body 23 is provided on the side wall of the first tube body 21, the second tube body 23 is connected to the first tube body 21, the first valve 24 is fixed to the second tube body 23, the first valve 24 is used to switch the connection state between the second tube body 23 and the outside, and the second tube body 23 is used to inject liquid into the first chamber 41 of the main tube 40. For example, the second tube body 23 is used to inject contrast agent into the first chamber 41 of the main tube 40. For ease of processing, the first tube body 21 and the second tube body 23 can be an integrated structure, and the valve is, for example, a three-way valve.

[0055] like Figure 6 As shown, the third exhaust assembly 30 further includes a second valve 34, a fourth tube body 33 is provided on the side wall of the third tube body 31, and the second valve 34 is fixed on the fourth tube body 33, and the connection state between the fourth tube body 33 and the outside is switched by the second valve 34. The third exhaust assembly 30 and the second exhaust assembly 20 have the same structural setting principle, so they are not described in detail.

[0056] The contrast agent can be used to assist in determining whether the position of the corresponding tube is appropriate. Taking the inner tube 50 as an example, when the suture system is used, the inner tube 50 needs to enter the human body and pass through the oval foramen to reach the left atrium. After the inner tube 50 enters the human body, the contrast agent can be injected into the fourth tube 33. The contrast agent passes through the fourth tube 33 and the third tube 31 and flows into the inner tube 50, and continues to flow along the inner tube 50 until the contrast agent flows out from the end of the inner tube 50 in the human body. The position of the end of the inner tube 50 placed in the human body can be seen through the contrast agent, so as to determine whether the position of the inner tube 50 is appropriate. In other embodiments, contrast agents may not be used, for example, the end of the inner tube 50 entering the human body is made of a developing metal material, so as to determine whether the position of the inner tube 50 is appropriate.

[0057] When using the stapler system, the guide wire 110 and the sheath 100 will first enter the human body. The guide wire 110 needs to pass through the first chamber 41 in the main body tube 40 to facilitate guiding the main body tube 40. As Figure 10 shown, the exhaust pipe 11 is located at the end of the main body tube 40. The guide wire 110 penetrates into the main body tube 40 and exits from the third knob 32 of the third exhaust assembly 30. This process may cause air to enter the end of the main body tube 40. At this time, heparin water can be injected into the liquid injection tube 11c in the first exhaust assembly 10 to exhaust the end of the main body tube 40.

[0058] The exhaust structure designed in this application can not only exhaust simultaneously, but also perform individual exhaust operations. For example, as Figure 11 shown, when it is necessary to exhaust the first chamber 41, heparin water can be injected into the first chamber 41 through the second tube body 23 in the second exhaust assembly 20. When there is liquid flowing out from the end of the main body tube 40 ( Figure 11 the leftmost end in it), it indicates that the exhaust of the first chamber 41 is successful. When exhausting the first chamber 41 individually, the first sealing ring is tightly fitted with the outer periphery of the main body tube, and the third knob is tightly fitted with the outer periphery of the push rod.

[0059] The above uses specific examples to elaborate on this application, which is only used to help understand this application and is not used to limit this application. For those skilled in the art of this application, according to the idea of this application, several simple deductions, deformations or substitutions can also be made.
