Description

Technical Field

[0001] This utility model belongs to the technical field of aftermarket connecting conduits, specifically relating to a Flexitron aftermarket connecting conduit that can be quickly disassembled and precisely connected. Background Technology

[0002] Connecting catheters play a crucial role in radiotherapy equipment, primarily establishing a safe and stable transmission channel between the radiation source reservoir and the applicator. This channel is of paramount importance, its core function being the precise and error-free transport of the radiation source from the reservoir to the applicator. During radiotherapy, the applicator relies on the accurately delivered radiation source to treat the patient. Furthermore, after each treatment session, the connecting catheter is responsible for safely returning the radiation source to the reservoir, ensuring proper storage and preventing potential radiation risks and other safety issues.

[0003] The existing post-loading machine connecting conduit lacks a support structure during use and may bend for various reasons, affecting the wire guide rope extraction and radiation source delivery, leading to conduit bending and unstable and inaccurate internal radiation source delivery. Utility Model Content

[0004] The purpose of this invention is to provide a Flexitron afterloading connection conduit that can be quickly disassembled and precisely connected, in order to solve the problems in the prior art where the existing afterloading connection conduit lacks a support structure during use, may bend due to various reasons, affect the wire guide rope extraction and radiation source delivery, and lead to conduit bending, unstable and inaccurate internal radiation source delivery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Flexitron aftermarket connection conduit that can be quickly disassembled and precisely connected, comprising a conduit body and a steel wire guide rope disposed inside the conduit body;

[0006] The catheter body is provided with connecting threaded heads at both ends of the first and last sides;

[0007] The end of the steel wire guide rope is provided with a feed source, and the end of the feed source is provided with a radiation source.

[0008] Multiple fixing frames are provided on the outer side of the catheter body, a clamping ring is provided on the inner side of the fixing frame, and a rotating shaft is provided at the connection between the clamping ring and the fixing frame;

[0009] An upper connecting seat is provided at the upper end of the fixed frame, and a front connecting seat is provided on the outer front side of the fixed frame. Limiting rods are provided on the inner sides of the upper connecting seat and the front connecting seat respectively.

[0010] Preferably, the rear end of the catheter body is provided with a retrofitting machine body, the front end of the catheter body is provided with an applicator, and the two ends of the catheter body are connected to the retrofitting machine body and the applicator respectively through connecting threaded heads.

[0011] Preferably, the steel wire guide rope passes through the main body of the conduit, and the radiation source is connected to the source delivery head by welding.

[0012] Preferably, the clamping ring rotates on the fixed frame via a pivot, and the end of the clamping ring is connected to the fixed frame via a snap-fit ​​connection.

[0013] Preferably, the upper connecting seat and the front connecting seat are connected to the fixed frame by a snap-fit ​​connection method, and the limiting rod is provided with a locking block at both ends.

[0014] Preferably, the limiting rod is connected to the upper connecting seat and the front connecting seat through the end blocks at both ends, and the fixing frame and the clamping ring are connected to the outside of the conduit body through the frame clamp connection method.

[0015] Compared with the prior art, this utility model provides a Flexitron aftermarket connection conduit that can be quickly disassembled and precisely connected, and has the following advantages:

[0016] Multiple fixing frames, clamps, and limiting rods connected to the outside of the catheter body form a stable support structure, effectively preventing excessive bending of the catheter during use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-5 The Flexitron aftermarket connection conduit shown includes a conduit body 1 and a steel wire guide rope 3 disposed inside the conduit body 1.

[0026] The two ends of the main body of the conduit 1 are respectively provided with connecting threaded heads 2;

[0027] The end of the steel wire guide rope 3 is equipped with a feed source 4, and the end of the feed source 4 is equipped with a radiation source 5;

[0028] Multiple fixing frames 6 are provided on the outer side of the catheter body 1, and clamping rings 9 are provided on the inner side of the fixing frames 6. A rotating shaft 10 is provided at the connection between the clamping rings 9 and the fixing frames 6.

[0029] An upper connecting seat 7 is provided at the upper end of the fixed frame 6, and a front connecting seat 11 is provided on the front exterior of the fixed frame 6. Limiting rods 8 are respectively provided on the inner sides of the upper connecting seat 7 and the front connecting seat 11.

[0030] In this embodiment, the user connects the threaded head 2 at the front end (rear end) of the conduit body 1 to the post-loading machine body, and then connects the threaded head 2 at the rear end (front end) of the conduit body 1 to the source applicator, ensuring a tight and well-sealed connection to prevent radiation source leakage. At this time, the radiation source 5 is in the initial position inside the post-loading machine body.

[0031] Next, the main body of the afterloading machine is started, and the main body of the afterloading machine drives the steel wire guide rope 3 to perform a pumping action. The steel wire guide rope 3 drives the delivery head 4 and the radiation source 5 to move along the inside of the catheter body 1 towards the applicator until the radiation source 5 reaches the predetermined radiotherapy position in the applicator for treatment.

[0032] After the treatment is completed, the afterloading unit reverses the drive of the steel wire guide rope 3 to retract the radiation source 5 and the delivery head 4 along the inside of the catheter body 1 into the afterloading unit.

[0033] The snap-fit ​​connection method is used to connect the clamping ring 9 to the fixed frame 6, the upper connecting seat 7 to the fixed frame 6, and the limiting rod 8 to the connecting seat. This connection method is not only easy to install, but also ensures the accuracy and reliability of the connection, so that the various components can be precisely connected together.

[0034] Optionally, the front end of the conduit body 1 is connected to a back-loading machine, and the back-loading machine is equipped with a drive device to drive the steel wire guide rope 3 to perform a pumping action.

[0035] Optionally, the main body of the afterloading unit drives the wire guide rope 3 to perform a pumping action via a drive device (such as a motor). Since the radiation source 5 is welded to the source delivery head 4, and the source delivery head 4 is connected to the end of the wire guide rope 3, the movement of the wire guide rope 3 will drive the radiation source 5 to move inside the conduit body 1, realizing the process of transporting and recovering the radiation source 5 from the main body of the afterloading unit to the source applicator.

[0036] like Figure 1-5 As shown, the rear end of the conduit body 1 is provided with a post-loading machine body, the front end of the conduit body 1 is provided with a source applicator, and the ends of the conduit body 1 are connected to the post-loading machine body and the source applicator respectively through the connecting threaded head 2. The steel wire guide rope 3 passes through the conduit body 1, and the radiation source 5 is connected to the source delivery head 4 by welding.

[0037] Optionally, the design of the threaded head 2 allows the conduit body 1 to be quickly connected and disconnected from the afterloading machine body and the applicator. The threaded connection method ensures both tightness and stability of the connection, while also facilitating operation and enabling the docking and separation process to be completed in a short time.

[0038] The clamping ring 9 rotates on the fixed frame 6 via the rotating shaft 10. The end of the clamping ring 9 is connected to the fixed frame 6 via a snap-fit ​​connection. The upper connecting seat 7 and the front connecting seat 11 are connected to the fixed frame 6 via snap-fit ​​connections. The limiting rod 8 is provided with locking blocks at both ends. The limiting rod 8 is internally connected to the upper connecting seat 7 and the front connecting seat 11 via the locking blocks at both ends. The fixed frame 6 and the clamping ring 9 are externally connected to the conduit body 1 via a frame clamp connection.

[0039] Preferably, the user can first install the fixing frame 6 and the clamping ring 9 on the outside of the catheter body 1 by means of frame clamp connection, and distribute multiple fixing frames 6 on the catheter body 1 at certain intervals. During installation, the clamping ring 9 is rotated to a suitable position by means of the rotating shaft 10, and then the end of the clamping ring 9 is firmly connected to the fixing frame 6 by means of snap-fit ​​connection.

[0040] Install the upper connecting seat 7 and the front connecting seat 11 into the corresponding positions of the fixed frame 6 by means of snap-fit ​​connection.

[0041] Take the limiting rod 8 and connect it to the upper connecting seat 7 and the front connecting seat 11 on the adjacent fixed frame 6 through the locking blocks at its two ends. Tighten the upper connecting seat 7 and the front connecting seat 11 on the fixed frame 6 to fix them, thereby completing the installation of the entire support structure.

[0042] Multiple fixing frames 6 are fixed to the outside of the catheter body 1 by frame clamps, and adjacent fixing frames 6 are connected by limiting rods 8 to form a support structure. When the catheter body 1 is subjected to external force and tends to bend, the limiting rods 8 will restrict the relative movement of the fixing frames 6, thereby limiting the degree of bending of the catheter body 1, ensuring that the steel wire guide rope 3 inside the catheter body 1 can be smoothly drawn, and avoiding the steel wire guide rope 3 from getting stuck or the radiation source 5 failing to accurately reach the predetermined position due to catheter bending.

[0043] During treatment, the support structure consisting of the fixing frame 6, clamping ring 9 and limiting rod 8 restricts the bending degree of the catheter body 1, ensuring that the steel wire guide rope 3 can be smoothly drawn, thereby ensuring that the radiation source 5 reaches the treatment position accurately and stably.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
