Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an auxiliary stent for interventional surgery, which is mainly used in intracranial aneurysm embolization. Background Technology

[0002] Interventional surgery is a minimally invasive medical procedure guided by imaging. It involves inserting sophisticated instruments such as catheters, guidewires, and stents into specific locations within the body via percutaneous puncture or natural cavities to achieve the purpose of disease diagnosis and treatment. This process requires the assembly and combination of numerous surgical devices and instruments, forming a complex and extensive interventional catheter system. Among these, the interventional catheter system for intracranial aneurysm embolization is the most complex. This explanation uses intracranial aneurysm embolization as an example.

[0003] Intracranial aneurysm embolization is a minimally invasive interventional treatment used to treat intracranial aneurysms, especially those that are difficult to clip directly through open craniotomy. This technique involves inserting a catheter into the patient's vascular system and placing a microembolic material (such as coils, flow diverters, etc.) into the aneurysm to seal the aneurysm cavity and prevent further expansion or rupture. The procedure is roughly as follows: Under local or general anesthesia, the surgeon inserts a guidewire and microcatheter into the target blood vessel in the brain via femoral or radial artery puncture. After confirming the aneurysm structure using digital subtraction angiography (DSA), an appropriate embolic material (such as coils, stents, or flow diverters) is selected based on the aneurysm characteristics for embolization. Intraoperative repeat angiography is used to monitor the embolization effect and vascular patency. Postoperatively, the catheter is removed and pressure is applied for hemostasis. Antiplatelet drugs may be necessary, and regular imaging follow-ups are required to assess aneurysm occlusion and vascular patency.

[0004] During the aforementioned intracranial aneurysm embolization procedure, the interventional catheter system is located outside the body and is used to deliver the stent / coil. Because the interventional catheter system is complex and large, with numerous components, such as when it has three to five Y-valve three-way catheter systems (containing a Y-valve, a three-way valve, and a catheter), the connection of these systems makes the entire system quite bulky. During the procedure, it is often placed between the patient's legs, resulting in an unstable position. This can lead to the Y-valve and three-way valve connections (threaded connections) easily breaking, or problems such as bending of the catheter, infusion tubing, or high-pressure injector connecting tubing.

[0005] Furthermore, since multiple high-pressure contrast imaging sessions are often required during the procedure, the high pressure of the contrast agent injected during the high-pressure contrast imaging process may cause the Y valve and three-way valve, which are already prone to disconnection, to disconnect. It may also cause the entire system to shift, being pushed from the sterile area to the contaminated area by the high-pressure contrast agent, thus leading to surgical safety issues. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] To address the issue that during existing intracranial aneurysm embolization procedures, the large interventional catheter system placed between the patient's legs poses a safety risk. During high-pressure angiography, the high pressure of the injected contrast agent may cause the already easily disconnectable Y-valve and T-stop to break, and may also cause the entire system to shift from the sterile area to the contaminated area by the high-pressure contrast agent, thus compromising surgical safety.

[0039] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an auxiliary stent for interventional surgery is provided, including a stent body 100 and a stent platform 200. The stent body 100 is mainly composed of four support rods 101, two transverse connecting rods 102, two longitudinal connecting rods 103, several platform support rods 104, two diagonal support rods 105 and one diagonal connecting rod 106.

[0040] Two horizontal connecting rods 102 and two vertical connecting rods 103 are connected end to end to form a square frame body. Several platform support rods 104 are arranged at intervals within the frame body. The support platform 200 is arranged on the several platform support rods 104. If the support platform 200 is a strap, the several platform support rods 104 are used to wrap the bandage.

[0041] The four corners of the main frame are vertically supported by four support rods 101, which provide support so that the entire auxiliary support is supported on the operating table. Furthermore, at the front and rear ends of one end of the frame, there are inclined support rods 105 arranged downwards. The front and rear inclined support rods 105 are connected by an inclined connecting rod 106, which is used to stabilize the position of the inclined support rods 105 and to wrap the bandages.

[0042] According to practical application needs, the support rod 101, horizontal connecting rod 102, longitudinal connecting rod 103, platform support rod 104, diagonal support rod 105, and diagonal connecting rod 106 are fixedly connected by welding, resulting in a stable and robust structure. Alternatively, as needed, the support rod 101, horizontal connecting rod 102, longitudinal connecting rod 103, platform support rod 104, diagonal support rod 105, and diagonal connecting rod 106 can be detachably connected using bolts and nuts, facilitating installation, disassembly, replacement, and maintenance.

[0043] According to the actual application requirements, the support rod 101, the horizontal connecting rod 102, the longitudinal connecting rod 103, the platform support rod 104, the diagonal support rod 105, the diagonal connecting rod 106, the first reinforcing rod 108 and the second reinforcing rod 109 are made of metal or plastic.

[0044] The metal is made of stainless steel or aluminum alloy, and the plastic is made of acrylic PMMA, polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), or polystyrene (PS). Preferably, each connecting rod is made of stainless steel, which provides structural strength and service life.

[0045] In some of these embodiments, such as Figure 4 and Figure 5As shown, according to actual application needs, the support rod 101, longitudinal connecting rod 103, platform support rod 104, diagonal support rod 105 and diagonal connecting rod 106 can be designed as telescopic rod structures, which can be manually adjusted to accommodate patients of different body types.

[0046] In some embodiments, depending on the actual application needs, the top ends of the four support rods 101 are respectively hinged to the frame body by pins, and are set to a rotating connection, so that the support rods 101 can be flipped inward at a certain angle for easy storage.

[0047] Similarly, according to the actual application needs, the top ends of the two inclined support rods 105 at one end are also connected to the frame body by a pin, and they are set to be rotated so that the inclined support rods 105 can be flipped inward at a certain angle for easy storage.

[0048] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, several platform support rods 104 are arranged longitudinally within the frame body and are arranged in parallel intervals with each other. Alternatively, depending on the actual application requirements, several platform support rods 104 may be arranged laterally or obliquely within the frame body and are arranged in parallel intervals with each other.

[0049] Of course, the platform support rods 104 are not limited to longitudinal spacing. They can be arranged according to the needs of different surgeries. For example, several of the platform support rods 104 can be arranged laterally or obliquely in the frame body. As long as they are set in the frame of the horizontal connecting rods 102 and the longitudinal connecting rods 103, they can be used for wrapping bandages and also play a role in stabilizing the entire auxiliary support.

[0050] In some of these embodiments, such as Figure 5 and Figure 6 As shown, in practical applications, surgical instruments, contrast agent bowls, water bowls, and other auxiliary instruments for interventional surgery may also be placed on one side of the patient's feet at the end of the operating table. Therefore, the other side of the auxiliary support also needs to be supported by inclined struts 105 and inclined connecting rods 106. The two inclined struts 105 are arranged at an angle downwards and are connected and fixed by inclined connecting rods 106. Medical instruments such as interventional catheter systems are placed on bandages wrapped around the inclined connecting rods 106.

[0051] In some embodiments, the length of the support rod 101 is 20-50cm, preferably 30cm; the length of the horizontal connecting rod 102 is 75-100cm, preferably 80cm; the length of the longitudinal connecting rod 103 is 45-60cm, preferably 53cm; the length of the platform support rod 104 is 41-56cm, preferably 48cm; the length of the diagonal support rod 105 is 35-45cm, preferably 35cm; and the length of the diagonal connecting rod 106 is 41-56cm, preferably 48cm.

[0052] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in order to improve the stability of the auxiliary support when used on the operating table and avoid slippage, anti-slip pads 107 are provided at the bottom of the support rod 101 and / or the inclined support rod 105. The anti-slip pads 107 are made of rubber.

[0053] In some of these embodiments, it is possible to Figure 1 and Figure 2 Based on this, a first reinforcing rod 108 and a second reinforcing rod 109 are also provided between the two support rods 101 on the same side, such as... Figure 7 As shown, the first reinforcing rod 108 is arranged horizontally, and the second reinforcing rod 109 is arranged at an angle to stabilize the auxiliary support. It is worth noting that the first reinforcing rod 108 and the second reinforcing rod 109 can only be added between the two support rods 101 on the same side of the patient's legs; otherwise, it will affect the insertion of the patient's legs.

[0054] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the support platform 200 is wrapped around several platform support rods 104 in a bandage manner, or wrapped around several platform support rods 104 and a diagonal connecting rod 106 at one end as needed, for placing medical devices such as interventional catheter systems.

[0055] Of course, depending on the actual application needs, the stent platform 200 may not use the method of wrapping bandages. For example, it can also be covered with cloth or an acrylic plate or plastic plate can be placed on the stent. During the operation, medical devices such as the interventional catheter system can be placed on the cloth, acrylic plate or plastic plate.

[0056] In some of these embodiments, such as Figure 8 , Figure 9 and Figure 10As shown, the auxiliary stent for interventional surgery includes a foot pedal 300 set at one end of the stent body 100. The patient's feet can rest on the foot pedal 300, which increases the patient's comfort and also makes it less likely for the patient's feet to move around during the operation.

[0057] As needed, the foot pedal 300 is configured to be adjustable in angle. As such, the foot pedal 300 is composed of a pedal body 301 and a hook 302. The bottom two ends of the pedal body 301 are hinged to the lower ends of the corresponding support rods 101. The left and right ends of the pedal body 301 are respectively adjustablely connected to a number of locking pins 110 on the outer side wall of the corresponding support rods 101 through the hooks 302. A number of strip-shaped through holes 308 are provided on the pedal body 301.

[0058] Specifically, first hinge blocks 303 are respectively provided at both ends of the bottom of the pedal body 301. The first hinge blocks 303 are hinged to second hinge blocks 305 through first pins 304. The second hinge blocks 305 are correspondingly fixedly connected to the lower end of the support rod 101. Second pins 306 are respectively provided at the left and right ends of the pedal body 301. The second pins 306 are hinged to one end of the hooks 302, and the other end of the hooks 302 is provided with hooks 307.

[0059] When in use, the pedal body 301 is manually rotated to a certain angle according to the position of the patient's feet, so as to support and fit the patient's feet tightly. This increases the patient's comfort and also prevents the patient's feet from wobbling during the operation. Then, the hook 307 at the other end of the hook 302 is fastened to the corresponding locking post 110 to fix the pedal body 301, thus realizing the adjustable control of the pedal body 301.

[0060] During interventional surgery, the supporting ends of the support rod 101 and the diagonal support rod 105 are placed on the operating table to maintain the stability of the entire auxiliary stent. A bandage, serving as the stent platform 200, is wrapped between the transverse connecting rod 102, the longitudinal connecting rod 103, the platform support rod 104, and the diagonal connecting rod 106. The patient's legs pass under the diagonal connecting rod 106, with their feet positioned under the longitudinal connecting rod 103 at the other end of the auxiliary stent. Medical devices such as the interventional catheter system are placed on the stent platform 200 wrapped around the auxiliary stent. This ensures stable operation of the interventional catheter system and other medical devices during use, overcoming safety issues present in existing technologies.
