Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a catheter fixator for clinical tumor treatment. Background Technology

[0002] A search revealed that Chinese patent CN220256942U discloses a catheter fixator for clinical treatment in oncology, comprising a movable base, an mounting frame fixedly mounted on the upper end of the movable base, an mounting plate fixedly mounted on the upper end of the mounting frame, and a microwave ablation therapy device fixedly mounted on the upper end of the mounting plate. The microwave ablation therapy device has a catheter connector on its front side. This utility model adopts the above structure, by inserting the catheter into the catheter connector, pulling the second clamping block with the second magnetic piece to separate it from the first clamping block with the first magnetic piece, then placing the catheter body in the clamping groove of the first clamping block, and then pushing the second clamping block to slide towards the first clamping block, so that the first magnetic piece and the second magnetic piece attract each other. At the same time, the first clamping block and the second clamping block complete the clamping of the catheter. Since an elastic cotton layer with an adhesive strip is added in the clamping groove, the catheter can be easily and stably clamped and fixed.

[0003] The microwave ablation catheter is an important component of a microwave ablation therapy device. It typically consists of a long, thin tube containing a microwave energy transmission system. This catheter can precisely deliver microwave energy to the lesion site that needs ablation, causing the diseased tissue to generate a thermal effect under the high-frequency oscillation of microwaves, thereby coagulating and necrosis, achieving the therapeutic goal.

[0004] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0005] As mentioned above, although existing oncology clinical treatment catheter fixators can effectively fix the catheter insertion end with magnetic clamps, in practical applications, problems such as dragging and pulling still exist for excessively long catheters. This not only affects the patient's comfort but may also increase the risk of catheter damage.

[0006] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model proposes a catheter fixation device for clinical treatment of tumors, which solves the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0009] A catheter fixation device for clinical tumor treatment includes a microwave ablation therapy instrument. The front of the microwave ablation therapy instrument is provided with an interface panel for inserting several catheters and several fixation mechanisms that allow for continuous bending and arrangement of the catheters.

[0010] The fixing mechanism includes a support frame arranged perpendicular to the front of the microwave ablation therapy device and several sliding seats for local installation and support of the catheter. The sliding seats are slidably assembled on the support frame and are all locked to the support frame by a first locking screw.

[0011] The support frame includes a mounting section and two side plates located on the left and right sides of the front of the mounting section, both extending outwards. The two side plates are parallel to each other, and a gap is reserved between them for the conduit to be confined and accommodated. The design of the support frame, especially the gap between the two side plates, provides space for the conduit to be confined and accommodated, enhancing the stability of the conduit during the fixing process and preventing the conduit from moving or falling off due to external forces.

[0012] Preferably, the device further includes a slide rod fixedly mounted on the microwave ablation therapy device and horizontally positioned below the interface panel. The mounting part is slidably fitted onto the slide rod and locked to it via a second locking screw threaded through its top. The design of the slide rod allows for lateral adjustment of the entire fixing mechanism on the microwave ablation therapy device, further improving its flexibility and convenience of use.

[0013] Preferably, the slide includes a movable block with two limiting holes for the two side plates to pass through. The guide tube is mounted through the slide, providing partial external protection for the guide tube when the slide detaches from the support frame. The two limiting holes also provide an elastic support structure.

[0014] Preferably, the movable block has a through hole in its center for the conduit to pass through, and a pressing block for local positioning of the conduit is slidably installed within the through hole. A screw for limiting the pressing block is threaded through the top of the movable block. Under the pressure and limiting effect of the screw, the pressing block locally positions and installs the conduit within the through hole. Because the movable block has a certain thickness, it provides structural support for the positioned conduit, preventing excessive bending that could affect the normal transmission of microwave energy. Simultaneously, the pressing block slidably installed within the through hole facilitates the local through-hole installation of the conduit.

[0015] The beneficial effects of this utility model are:

[0016] The technical solution of this utility model provides a support structure for storing excessively long catheters by setting several fixing mechanisms on the front of the microwave ablation therapy device for continuous bending and arrangement of catheters. At the same time, with the help of the sliding mount mounted on the support frame and the first locking screw that can fix the mount, the length of the catheter can be easily adjusted, reducing the phenomenon of catheter dragging on the ground and improving the flexibility of use.

[0029] 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.

[0030] Please see Figure 1-5This utility model provides a technical solution: a catheter fixation device for clinical tumor treatment, including a microwave ablation therapy device 100. The front of the microwave ablation therapy device 100 is provided with an interface panel 110 for inserting several catheters and several fixing mechanisms 200 for continuous bending arrangement of catheters. The fixing mechanism 200 includes a support frame 210 arranged perpendicular to the front of the microwave ablation therapy device 100 and several slides 220 for partial installation and support of catheters. The several slides 220 are slidably assembled on the support frame 210 and are all locked to the support frame 210 by a first locking screw 230. The support frame 210 includes a mounting part 2110 and two side plates 2120 respectively provided on the left and right sides of the front of the mounting part 2110 and extending outward. The two side plates 2120 are parallel to each other and a gap is reserved between them for catheter positioning and accommodation.

[0031] Based on the above structural design, this tumor clinical treatment catheter fixator consists of a microwave ablation therapy device 100 and several fixation mechanisms 200. The microwave ablation therapy device 100 has an interface panel 110 on its front for inserting several catheters and provides structural support for the fixation mechanisms 200. Specifically, during use, medical personnel first install slides 220 at equal intervals on the catheter. Then, they insert the catheter's input end into the interface panel 110. Subsequently, they mount the slides 220 onto the support frame 210, adjust the catheter to a continuously curved arrangement, and store it on the support frame 210. Several first locking screws 230 are used to lock and fix the slides 220. In subsequent adjustments to the catheter length, for short distances, medical personnel can adjust the position of the slides 220; for long distances... The number of slides 220 on the support frame 210 can be adjusted by removing or adding slides 220 to increase or decrease the catheter length, respectively. The sliding assembly of the slides 220 on the support frame 210 and the locking connection through the first locking screw 230 allow the position and layout of the catheter to be flexibly adjusted according to actual needs, adapting to the needs of catheters of different lengths and curvatures. This tumor clinical treatment catheter fixator, by providing several fixing mechanisms 200 on the front of the microwave ablation therapy device 100 for continuous bending of the catheter, can provide a storage support structure for excessively long catheters. At the same time, by means of the slides 220 slidably assembled on the support frame 210, and in conjunction with the first locking screw 230 for fixing the slides 220, the length of the catheter can be easily adjusted, reducing the phenomenon of the catheter dragging on the ground and improving the flexibility of use.

[0032] Furthermore, it also includes a slide rod 120 that is fixedly installed on the microwave ablation therapy device 100 and horizontally mounted below the interface panel 110. The mounting part 2110 is slidably fitted onto the slide rod 120 and locked to the slide rod 120 by a second locking screw 2130 threaded through its top.

[0033] Furthermore, the slide 220 includes a movable block 2210, which has two limiting holes 2220 that can be respectively adapted to and passed through by the two side plates 2120.

[0034] Furthermore, the movable block 2210 has a through hole 2230 in the middle for the conduit to pass through, and a pressing block 2240 for local positioning of the conduit is slidably installed in the through hole 2230. A screw 2250 for limiting the pressing block 2240 is threaded through the top of the movable block 2210.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
