Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to a catheter for interventional therapy. Background Art

[0002] The contents of this section merely provide background information related to the present invention and may not constitute prior art.

[0003] Interventional therapy is a minimally invasive treatment method that introduces special catheters and other precision medical devices into the human body under the guidance of medical imaging equipment to diagnose and treat human diseases.

[0004] Generally, in interventional therapy, the catheter includes not only the portion introduced into the human body, but also a portion located outside the human body (such as the filling tube that constitutes the catheter). The portion of the catheter located outside the human body usually needs to be temporarily fixed to prevent the portion of the catheter located outside the human body from being suspended and moving, thereby affecting the normal progress of the interventional therapy.

[0005] However, known interventional therapy catheters do not have the ability to be fixed. Typically, the portion of the catheter located outside the human body often needs to be manually lifted by medical staff, which increases the labor intensity of the medical staff. In addition, the portion of the catheter located outside the human body is susceptible to movement due to human factors. For example, the medical staff may accidentally drag the portion of the catheter located outside the human body, causing the catheter to move. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide an interventional therapy catheter, in particular an interventional therapy catheter with fixation capability, in the hope of reducing the labor intensity of medical staff during interventional therapy and minimizing the risk of catheter movement.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific implementation methods. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described 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.

[0035] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0036] The embodiment of the utility model discloses a catheter for interventional therapy, and in particular, may be a catheter for interventional therapy with fixation capability.

[0037] like Figure 1 As shown in FIG, it shows the general structure of the exemplary catheter disclosed in this embodiment. Figure 1 In the catheter shown, the catheter may include a catheter body 10 and a fixing mechanism 20 .

[0038] In this embodiment, the catheter body 10 may be the portion of an interventional therapy catheter known in the prior art that is located outside the human body during actual use. For example, the catheter body 10 may be the filling tube of an interventional therapy catheter known in the prior art. Since the structure of the catheter body 10 is not improved in this embodiment, the specific construction of the catheter body 10 may refer to the construction described in the prior art for interventional therapy catheters and will not be further described here.

[0039] In this embodiment, the fixing mechanism 20 is suitable for fixing the catheter body 10 to an external fixing member (not shown) outside the human body. For example, the external fixing member may be a bed rail on which a patient undergoing interventional treatment lies.

[0040] The fixing mechanism 20 may be constructed in the following manner but is not limited thereto.

[0041] Specifically, the fixing mechanism 20 may include an anti-slip component 21 , a clamping component 22 and a connecting component 23 .

[0042] Combine Figure 2 and Figure 3As shown, the anti-slip member 21 may be a generally annular member, so as to define an anti-slip passage 211 suitable for the catheter body 10 to pass through and an anti-slip inlet and outlet 212 communicating with the anti-slip passage 211. The anti-slip inlet and outlet 212 is used to connect the anti-slip passage 211 with the external space, so that the catheter body 10 in the external space can enter the anti-slip passage 211 with the help of the anti-slip inlet and outlet 212.

[0043] At the same time, an opening and closing member 24 may be provided at the anti-slip inlet and outlet 212. The opening and closing member 24 is configured to open or close the anti-slip inlet and outlet 212. Specifically, when the catheter body 10 in the external space needs to enter the anti-slip passage 211, the anti-slip inlet and outlet 212 is first opened by the opening and closing member 24 to facilitate the catheter body 10 to enter the anti-slip passage 211 through the anti-slip inlet and outlet 212. After the catheter body 10 enters the anti-slip passage 211, the opening and closing member 24 can close the anti-slip inlet and outlet 212 to prevent the catheter body 10 in the anti-slip passage 211 from escaping from the anti-slip passage 211.

[0044] like Figure 2 or Figure 3 As shown, the clamping member 22 can be fixedly arranged in the anti-slip channel 211, for example, the clamping member 22 can be fixedly connected to the inner wall of the anti-slip channel 211. The clamping member 22 defines a clamping channel 221 that matches the catheter body 10 and a clamping inlet and outlet 222 that is connected to the clamping channel 221. The clamping inlet and outlet 222 is used to connect the clamping channel 221 with the anti-slip channel 211. In this way, in combination with the above, when the catheter body 10 enters the anti-slip channel 211, the catheter body 10 can further enter the clamping channel 221 through the clamping inlet and outlet 222. The clamping member 22 is also configured to apply a clamping force to the catheter body 10 in the clamping channel 221 to clamp and position the catheter body 10 located in the clamping channel 221.

[0045] It can be understood that by further arranging a clamping member 22 with a clamping channel 221 in the anti-slip channel 211, the catheter body 10 can be clamped and positioned by the clamping member 22 after entering the clamping channel 221, so that the catheter body 10 can be effectively prevented from moving during the interventional treatment, thereby reducing the risk of movement of the entire interventional treatment catheter as much as possible.

[0046] In order to simplify the structure of the clamping member 22 as much as possible, refer to Figure 3 As shown, the clamping member 22 can be a substantially C-shaped elastic clip. In addition, the clamping inlet 222 on the clamping member 22 can be aligned with the anti-slip inlet 212, so that the catheter body 10 entering the anti-slip channel 211 through the anti-slip inlet 212 can directly enter the clamping channel 221 through the clamping inlet 222.

[0047] And, continue to refer to Figure 3 Clamping guides 223 may also be provided on the clamping member 22 on either side of the clamping inlet 222. The two clamping guides 223 are outwardly curved, with rounded corners at the ends of each. This facilitates smoother entry of the catheter body 10 through the clamping inlet 222 into the clamping channel 221 and effectively prevents the clamping member 22 from causing scratches or other adverse effects on the catheter body 10 passing through the clamping inlet 222.

[0048] Combine Figure 2 As shown, the connector 23 can be fixedly mounted on the anti-slip member 21. For example, if the anti-slip inlet 212 is located at the bottom of the anti-slip member 21, the connector 23 can be fixedly mounted on the top of the anti-slip member 21. Furthermore, the connector 23 is configured to be detachably connected to the aforementioned external fixing member. In other words, the provision of the connector 23 enables the entire fixing mechanism 20 to be temporarily fixed to the external fixing member or to be removed from the external fixing member.

[0049] Based on the above arrangement, during the interventional treatment, if the catheter body 10 needs to be temporarily fixed, combined with the above, the catheter body 10 can first be allowed to enter the anti-slip channel 211 through the anti-slip inlet and outlet 212, and then the catheter body 10 entering the anti-slip channel 211 can be allowed to enter the clamping channel 221 through the clamping inlet and outlet 222, so as to pass through the clamping member 22 as shown in FIG. Figure 4 The catheter body 10 entering the clamping channel 221 is clamped and positioned in the manner shown. Subsequently, the anti-dropout inlet and outlet 212 is closed using the opening and closing member 24, and the connecting member 23 is connected to the corresponding external fixing member to achieve temporary fixation of the catheter body 10.

[0050] It can be seen that the interventional treatment catheter disclosed in this embodiment can clamp and position the catheter body 10 by adding a fixing mechanism 20 to the catheter body 10, and can temporarily fix the clamped and positioned catheter body 10 to an external fixing member, so as to replace the medical staff in temporarily fixing the catheter body 10 during the interventional treatment process, thereby helping to reduce the labor intensity of the medical staff and reducing the risk of catheter movement.

[0051] At the same time, the fixing mechanism 20 disclosed in this embodiment is provided with an anti-slip member 21 having an anti-slip channel 211 and an anti-slip inlet and outlet 212, and an opening and closing member 24 for opening or closing the anti-slip inlet and outlet 212. When the opening and closing member 24 closes the anti-slip inlet and outlet 212, even if the catheter body 10 accidentally slips off the clamping member 22, the catheter body 10 will continue to be confined within the anti-slip channel 211, thereby reliably preventing the catheter body 10 from hanging in the event of an accident. In addition, the provision of the anti-slip inlet and outlet 212 facilitates the convenient separation of the catheter body 10 from the entire fixing mechanism 20. For example, when an interventional therapy catheter is actually used, with one end of the catheter introduced into the human body and the other end connected to medical imaging equipment, the catheter body 10 can be separated from the entire fixing mechanism 20.

[0052] The opening and closing member 24 may open or close the anti-slip inlet and outlet 212 in the following manner, but is not limited thereto.

[0053] Combine Figure 3 As shown, the anti-slip member 21 has a first end 213 and a second end 214 opposite each other, with an anti-slip inlet 212 formed between the first end 213 and the second end 214 of the anti-slip member 21. The anti-slip member 21 defines a sliding groove 215 extending around the anti-slip passage 211. One end of the sliding groove 215 extends through the first end 213 of the anti-slip member 21. In this embodiment, the sliding groove 215 is generally C-shaped.

[0054] The opening and closing member 24 slides within the sliding groove 215. Furthermore, the opening and closing member 24 is configured to move along the extending direction of the sliding groove 215 to open or close the anti-escape entrance 212. The cross-sectional shape of the sliding groove 215 can be the same as that of the opening and closing member 24, so that the outer wall of the opening and closing member 24 can contact and fit with the inner wall of the sliding groove 215, thereby improving the reliability of the opening and closing member 24 when sliding within the sliding groove 215.

[0055] Assume that, in the initial state, the opening and closing member 24 is in the position closing the anti-dropout entrance 212. Based on this, when the anti-dropout entrance 212 needs to be opened, the opening and closing member 24 only needs to be moved in the sliding groove 215 in a direction away from the second end 214 of the anti-dropout member 21; conversely, the opening and closing member 24 only needs to be moved in the sliding groove 215 in a direction close to the second end 214 of the anti-dropout member 21 to close the anti-dropout entrance 212 again.

[0056] It is understandable that arranging the anti-slip member 21 and the opening and closing member 24 in the above manner can further optimize the structure of the entire fixing mechanism 20 and is conducive to providing certain protection for the opening and closing member 24 through the sliding groove 215, thereby extending the service life of the opening and closing member 24.

[0057] In order to further simplify the process of opening or closing the anti-dropout entrance and exit 212 using the opening and closing member 24, as shown in FIG. Figure 3 As shown, an elastic member 25 may be further disposed in the sliding groove 215 for elastically maintaining the opening and closing member 24 in a position to close the anti-escape entrance 212. For example, the elastic member 25 may be a tension spring disposed in the sliding groove 215, one end of the tension spring may be connected to the opening and closing member 24, and the other end of the tension spring may be fixed to the innermost wall of the sliding groove 215.

[0058] At the same time, combined Figure 2 As shown, the side wall of the anti-slip member 21 is further provided with an escape opening 216 extending along the extension direction of the sliding groove 215, and the escape opening 216 is connected to the sliding groove 215. Among them, the opening and closing member 24 is further provided with a toggle member 26, which extends outside the sliding groove 215 after passing through the escape opening 216.

[0059] Based on the above configuration, assuming that in the initial state, the opening and closing member 24 is kept in the position as shown below under the action of the elastic member 25. Figure 3 The position of the anti-drop-out entrance 212 is shown as closed. On this basis, when it is necessary to open the anti-drop-out entrance 212, it is only necessary to hold the toggle member 26 to move the opening and closing member 24 in a direction away from the second end 214 of the anti-drop-out member 21. During this process, the elastic member 25 will undergo elastic deformation and pre-store an elastic force; accordingly, when it is necessary to close the anti-drop-out entrance 212, it is only necessary to release the toggle member 26 to release the pre-stored elastic force of the elastic member 25. At this time, the opening and closing member 24 will move toward the second end 214 of the anti-drop-out member 21 under the elastic force of the elastic member 25 to re-close the anti-drop-out entrance 212.

[0060] like Figure 3 As shown, an insertion groove 217 that matches the opening and closing member 24 can also be provided at the second end 214 of the anti-slip member 21. Furthermore, when the opening and closing member 24 is in a position closing the anti-slip inlet and outlet 212 under the action of the elastic member 25, a portion of the opening and closing member 24 can extend into the insertion groove 217. This helps improve the reliability of the opening and closing member 24 when it is in the position closing the anti-slip inlet and outlet 212.

[0061] In combination with the foregoing, when the external fixing member is a bed rail or other bed rail-like component, based on the known bed rails of a hospital bed, which can usually be made of magnetic metal material (such as iron) or plastic, it is possible to consider setting the connecting member 23 in a form that can be fixed to an external fixing member made of magnetic metal material or to an external fixing member made of plastic, so as to expand the way in which the connecting member 23 is fixed to the external fixing member.

[0062] Specifically, combined Figure 3As shown in the content, the connecting member 23 may further include a connecting column 231 and a connecting platform 232. The connecting column 231 may be connected to the anti-slip member 21, such as the top of the anti-slip member 21. The connecting platform 232 has a first side and a second side relative to each other, wherein the connecting column 231 is configured to be selectively connected to the first side or the second side of the connecting platform 232. In other words, the connecting column 231 can be connected to both the first side and the second side of the connecting platform 232. For example, the connecting column 231 may be a screw with an external thread. In this case, an internal threaded hole (for example, a threaded hole) adapted to the connecting column 231 may be provided on both the first side and the second side of the connecting platform 232. Figure 4 23 ), so that the connecting post 231 can be threadedly connected to both the first side of the connecting platform 232 and the second side of the connecting platform 232.

[0063] At the same time, a magnetic portion 233 suitable for adsorbing on an external fixing part made of a magnetic metal material is provided on the first side of the connecting platform 232, and an adhesive portion 234 suitable for adhering to an external fixing part made of plastic is provided on the second side of the connecting platform 232. The magnetic portion 233 can be a permanent magnet, and the adhesive portion 234 can be a double-sided adhesive tape. In addition, a protective film 235 such as release paper is provided on the side of the adhesive portion 234 facing away from the connecting platform 232, so that the unused adhesive portion 234 can be protected by the protective film 235, and the protective film 235 has an easy-to-tear portion 2351 protruding from the outer edge of the adhesive portion 234, so that the protective film 235 can be torn off from the adhesive portion 234 by operating the easy-to-tear portion 2351.

[0064] Based on the above arrangement, in actual application, the connecting member 23 can be fixed to the external fixing member in an appropriate manner according to the material type of the external fixing member. For example, when the external fixing member is made of a magnetic metal material, the connecting post 231 can be connected to the second side of the connecting platform 232 to expose the magnetic attraction portion 233 located on the first side of the connecting platform 232. Subsequently, the connecting member 23 can be temporarily fixed by allowing the magnetic attraction portion 233 to be adsorbed on the external fixing member. When the external fixing member is made of plastic, the connecting post 231 can be connected to the first side of the connecting platform 232 (i.e., Figure 3 The adhesive portion 234 on the second side of the connecting platform 232 is exposed, and then the protective film 235 on the adhesive portion 234 is removed, and the connecting member 23 can be temporarily fixed by sticking the adhesive portion 234 on the external fixing member.

[0065] It should be noted that although the drawings of this embodiment only show a situation where one fixing mechanism 20 is provided on the catheter body 10, the number of fixing mechanisms 20 is not limited to this. For example, when the catheter body 10 is long, more fixing mechanisms 20 can be provided in sequence along the length direction of the catheter body 10 to achieve temporary fixation of the catheter body 10, so as to improve the reliability of the catheter body 10 after being temporarily fixed.

[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
