Description

Technical Field

[0001] This utility model belongs to the field of balloon dilation catheter technology, specifically a balloon dilation catheter with anti-dislodgement function. Background Technology

[0002] In medical practice, balloon dilation catheters are an important medical device widely used in various interventional procedures, such as surgical treatment of cardiovascular, cerebrovascular and peripheral blood vessels.

[0003] Current practices often involve using tape to temporarily secure the tubing of a balloon dilation catheter to the surgical table. However, this method has several drawbacks. Due to factors such as movement of the surgical table, patient positioning adjustments, and the surgeon's actions during the procedure, the tape-secured tubing can easily detach. This not only disrupts the surgical process and affects its continuity but may also cause unnecessary inconvenience to the surgeon and even increase the patient's surgical risks. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a balloon dilation catheter with anti-dislodgement function, solving the problem that in the prior art, the tape-fixed tubing is prone to dislodgement, which not only interrupts the surgical process and affects the continuity of the surgery, but may also cause unnecessary trouble for the surgical staff and even increase the surgical risk for the patient.

[0005] A balloon dilation catheter with anti-dislodgement function includes: a main body, including a catheter assembly, a balloon mounted on the catheter assembly, and a connecting assembly;

[0006] The fixing mechanism includes a fixing component mounted on the connecting component and a clamping plate component slidably engaged with the fixing component;

[0007] The fixing component includes a fixing block, a fixing ring is fixedly connected to the fixing block, and a set of sliding grooves are formed on the fixing block;

[0008] The clamping plate assembly includes a limiting ring slidably connected in a set of grooves, one end of a guide rod is fixedly connected to the limiting ring, the other end of the guide rod extends to the outside of the fixing block and is fixedly connected to the clamping plate body, a spring is sleeved on the outside of the guide rod, and a handle is fixedly connected to the clamping plate body.

[0009] Preferably, the catheter assembly includes a catheter body, the catheter body having a guidewire cavity for guidewire passage inside, the catheter body also having a filling cavity for filling the connecting assembly inside, and the catheter body having printed scale lines on the outside.

[0010] Preferably, the balloon is fixedly connected to the outside of the catheter body and communicates with the filling cavity inside the catheter body.

[0011] Preferably, the connecting assembly includes a guidewire inlet / outlet tube and an filling tube. The filling tube is connected to the end of the catheter body away from the balloon. The guidewire inlet / outlet tube communicates with the guidewire lumen inside the catheter body. The fixing block is fixedly connected to the outside of the guidewire inlet / outlet tube by a fixing ring.

[0012] Preferably, the filling tube is fixedly connected to the guidewire inlet / outlet tube, and the filling tube is connected to the filling cavity inside the catheter body.

[0013] Preferably, a pressure sensor is installed inside the filling lumen of the catheter body and at the junction with the balloon to measure the pressure inside the filling lumen in real time.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model allows the device to be securely locked onto the worktable by pulling the handle until the distance between the clamp body and the fixing block increases sufficiently to lock it onto the worktable. Then, by releasing the handle, the spring will push the limiting ring to move due to its restoring deformation, thereby driving the clamp body to return to its original position. This ensures the stability of the main mechanism on the worktable, effectively prevents shaking during operation, and improves the accuracy and safety of the surgery.

[0016] 2. This utility model, through the configuration of a pressure sensor and with the aid of an external pressure monitoring device, obtains the pressure value inside the inflation cavity in real time and accurately, ensuring that the inflation pressure of the balloon is always maintained within a safe and appropriate range. During the operation, the doctor can flexibly adjust the output of the inflation device according to the real-time pressure monitoring data and the specific needs of the operation, thereby achieving precise control over the degree of balloon inflation and the pressure inside the inflation cavity, thus improving the safety and accuracy of the operation.

Detailed Implementation

[0022] 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.

[0023] like Figures 1 to 4 As shown:

[0024] Example 1: This utility model provides a balloon dilation catheter with anti-dislodgement function, including: a main body 1, including a catheter assembly 11, a balloon 12 installed on the catheter assembly 11, and a connecting assembly 13;

[0025] The fixing mechanism 2 includes a fixing component 21 installed on the connecting component 13 and a clamping plate component 22 that is slidably engaged on the fixing component 21;

[0026] The fixing component 21 includes a fixing block 211, a fixing ring 212 fixedly connected to the fixing block 211, and a set of sliding grooves 213 formed on the fixing block 211;

[0027] The clamp assembly 22 includes a limiting ring 221 slidably connected in a set of grooves 213. One end of a guide rod 222 is fixedly connected to the limiting ring 221. The other end of the guide rod 222 extends to the outside of the fixing block 211 and is fixedly connected to the clamp body 223. A spring 224 is sleeved on the outside of the guide rod 222. A handle 225 is fixedly connected to the clamp body 223.

[0028] Specifically, the catheter assembly 11 includes a catheter body 111, the catheter body 111 has a guidewire cavity for guidewire passage inside, the catheter body 111 also has a filling cavity for filling the connecting assembly 13 inside, and scale lines 112 are printed on the outside of the catheter body 111.

[0029] Specifically, the balloon 12 is fixedly connected to the outside of the catheter body 111 and communicates with the filling cavity inside the catheter body 111.

[0030] Specifically, the connecting assembly 13 includes a guidewire inlet / outlet tube 131 and an filling tube 132. The filling tube 132 is connected to the end of the catheter body 111 away from the balloon 12. The guidewire inlet / outlet tube 131 is connected to the guidewire cavity inside the catheter body 111. The fixing block 211 is fixedly connected to the outside of the guidewire inlet / outlet tube 131 by a fixing ring 212.

[0031] Specifically, the filling tube 132 is fixedly connected to the guidewire inlet / outlet tube 131, and the filling tube 132 is connected to the filling cavity inside the catheter body 111.

[0032] As can be seen from the above, during use, first pull the handle 225. This action will cause the clamping plate body 223 to move smoothly under the guidance of the guide rod 222. At the same time, the spring 224 will be in a compressed state until the distance between the clamping plate body 223 and the fixing block 211 increases to a level sufficient to lock it onto the worktable. Then, release the handle 225. At this time, the spring 224 will push the limit ring 221 to move due to the restoration of its deformation, thereby causing the clamping plate body 223 to return to its original position, thus firmly locking and fixing the equipment on the worktable, ensuring the stability of the main mechanism 1 on the worktable, and effectively preventing shaking during operation. This improves the precision and safety of the surgery. Next, the guidewire is smoothly inserted into the guidewire lumen inside the catheter body 111 through the guidewire inlet / outlet tube 131 until the guidewire reaches the predetermined position. Then, the filling tube 132 is connected to the external pressure filling device to prepare for the inflation operation of the balloon 12. After the switch of the filling device is turned on, an appropriate amount of liquid or gas will be injected into the filling chamber, causing the balloon 12 to gradually inflate to the predetermined size. During this process, we can observe the clearly printed scale lines 112 on the catheter body 111 to roughly judge the depth of balloon insertion and the degree of inflation.

[0033] Example 2: This example is basically the same as the previous example, except that a pressure sensor is installed in the filling lumen of the catheter body 111 and at the junction with the balloon 12 to measure the pressure in the filling lumen in real time.

[0034] As can be seen from the above, the configuration of the pressure sensor, with the help of external pressure monitoring equipment, can obtain the pressure value inside the inflation cavity in real time and accurately, ensuring that the inflation pressure of the balloon is always maintained within a safe and appropriate range. During the operation, the doctor can flexibly adjust the output of the inflation device according to the real-time pressure monitoring data and the specific needs of the operation, thereby achieving precise control over the degree of balloon inflation and the pressure inside the inflation cavity, thus improving the safety and accuracy of the operation.

[0038] Guide wire insertion:

[0039] The guidewire is inserted into the guidewire lumen of the catheter body 111 through the guidewire inlet / outlet tube 131 to ensure that the guidewire reaches the predetermined position smoothly.

[0040] Abundant preparation:

[0041] Connect the filling tube 132 to the external pressure filling device to ensure that the filling tube 132 is in communication with the filling cavity of the catheter body 111.
