Description

Technical Field

[0001] The utility model belongs to the research field of medical devices, and in particular relates to an auxiliary device for femoral artery access interventional surgery. Background Art

[0002] The femoral artery is a direct continuation of the external iliac artery. It originates from the posterior midpoint of the inguinal ligament, passes through the vascular space into the femoral triangle, and from the tip of the femoral triangle, descends into the adductor canal, passes through the adductor magnus hiatus, and reaches the popliteal fossa, where it becomes the popliteal artery. Interventional therapy, a key component of interventional radiology, is based on diagnostic imaging and utilizes catheters, puncture needles, and other interventional devices to treat diseases.

[0003] Interventional therapy covers a wide range of conditions and can be used to treat vascular diseases, including arteriovenous stenosis and occlusion, aortic dissection, abdominal aortic aneurysm, acute arterial hemorrhagic disease, portal hypertension, and intracranial vascular disease, as well as non-vascular diseases, including the treatment of benign and malignant tumors, such as primary liver cancer, lung cancer, pancreatic cancer, and uterine fibroids. Compared to surgical procedures, interventional therapy significantly reduces surgical risk and damage to organs and tissues, achieving the goal of localized treatment.

[0004] Currently, the most common access method in interventional surgery is the femoral artery puncture approach. For other basic or complex interventional operations, the interventional equipment required for the femoral artery puncture approach often needs to be connected multiple times to derive 2-4 catheters. In the current traditional interventional surgery operations using the femoral artery puncture approach, these catheters are often exposed naked on the patient's thigh, the operating surface is uneven, and there is a lack of clear identification to distinguish between the catheters. This often leads to confusion among the many catheters, increasing the difficulty of operation. If the catheter is accidentally touched, it may even slip, increasing the patient's operational risk. The above situation is more serious when the operator operates for a long time or is fatigued.

[0005] Therefore, there is an urgent need to design an operating platform that is easy to distinguish and fix the catheter to reduce the risk of confusing the pathway during interventional surgery. Summary of the Invention

[0006] The purpose of the utility model is to overcome the problem that in existing interventional surgery, the catheter is placed naked on the patient's thigh, which makes many catheters confusing and difficult to operate. If the catheter is accidentally touched, it may even slip and pull the patient's surgical puncture point, increasing the patient's operation risk.

[0007] In order to achieve the above-mentioned purpose, the technical idea adopted by the present invention is: to set up an auxiliary device for femoral artery access interventional surgery, including a base plate and an operating table connected to the base plate; a movable cavity is provided between the base plate and the operating table so that the patient's lower leg can be placed between the base plate and the operating table. Since there are multiple catheter separation slots on the operating table, the catheters connected to the patient can be placed respectively in the catheter separation slots on the operating table to achieve the distinction of the catheters, so that the doctor can better perform the interventional surgery and ensure the smooth progress of the operation.

[0008] Based on the above technical ideas, the technical solution adopted by this utility model is:

[0009] An auxiliary device for femoral artery access interventional surgery, comprising:

[0010] The operating table is provided with a plurality of catheter separation slots arranged in parallel; the catheter separation slots are used to fix the catheter;

[0011] The bottom plate is arranged below the operating table and is slidably connected to the operating table through a bracket.

[0012] To further limit the above technical solution, preferably, the bottom surface of the operating table is provided with two parallel limit blocks, and each limit block is provided with a slide groove;

[0013] The operating table is slidably connected to the bracket through a sliding groove.

[0014] As a further limitation of the above technical solution, the catheter separation groove is an arc-shaped groove.

[0015] Further limiting the above technical solution, the bracket includes:

[0016] Fixed pipe, connected to the bottom plate;

[0017] The upper end of the height adjustment rod is slidably connected to the operating table, and the lower end is sleeved with the fixed pipe.

[0018] As a further limitation of the above technical solution, the fixed tube is an L-shaped structure.

[0019] As a further limitation of the above technical solution, the height adjustment rod is a π-shaped structure.

[0020] As a further limitation of the above technical solution, a limiting plate for fixing the catheter is provided in the catheter separation groove.

[0021] Beneficial effects of the utility model:

[0022] 1. The utility model provides an auxiliary device for femoral artery access interventional surgery, including a base plate and an operating table connected to the base plate; a movable cavity is provided between the base plate and the operating table so that the patient's lower leg can be placed on the base plate. Since the operating table is provided with multiple catheter separation slots, the catheters connected to the patient can be placed in the catheter separation slots on the operating table respectively, so that multiple catheters can be distinguished during surgery, reducing the risk of confusing catheter pathways during surgery. Each catheter can also be fixed in the catheter separation slot to further avoid accidents, so that doctors can better perform interventional surgery and ensure the smooth progress of the operation.

[0023] 2. The catheter separation groove provided by the present invention is an arc-shaped groove. In this way, when the catheter is placed in the arc-shaped groove, the catheter will not move left and right on the operating table. In this way, multiple catheter separation grooves arranged in parallel can be set to distinguish multiple catheters in interventional surgery and avoid catheter confusion.

[0024] 3. The bracket provided by the utility model is a height-adjusting component, which can adjust the height of the operating table according to the height and body shape of different patients and the actual surgical scene, so that the operating table can be placed above the patient's legs without affecting the doctor's normal surgical operation.

[0025] Fourth, the utility model can move the horizontal position of the operating table by slidingly connecting the operating table with the height adjustment rod, thereby avoiding blocking the patient's puncture point and ensuring smooth operation.

[0026] 5. The utility model can increase the friction between the catheter and the operating table through the combined design of the catheter separation groove and the limit plate, thereby further improving the stability of the catheter. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0039] The inventors have discovered that in current interventional surgeries, there is a lack of clear identification between catheters, which often leads to confusion among the multiple catheters and increases the difficulty of operation. If a catheter is accidentally touched, it may even slip, increasing the operational risk for the patient. The above situation is more serious when the operator is operating for a long time or is fatigued.

[0040] Based on the above findings, the present application proposes an auxiliary device for femoral artery access interventional surgery, including a base plate and an operating table connected to the base plate; a movable cavity is provided between the base plate and the operating table so that the patient's lower leg can be placed on the base plate. Since a plurality of catheter separation slots are provided on the operating table, the catheters connected to the patient can be placed separately in the catheter separation slots on the operating table to achieve the distinction of the catheters, so that by fixing the catheters separately, the doctor can better perform the interventional surgery and ensure the smooth progress of the operation.

[0041] Example 1

[0042] like Figure 1-5 As shown, an auxiliary device for femoral artery access interventional surgery provided by the present invention includes an operating table 1, a base plate 3 and a bracket 4; wherein the bracket 4 includes a fixing tube 41, a height adjustment rod 42 and a fixing bolt 43.

[0043] The operating table 1 is provided with a plurality of parallel catheter separation slots 2 for separating the catheters used in interventional procedures. It should be noted that the present embodiment does not limit the number of catheter separation slots 2. For purposes of illustration, the present embodiment is described using an operating table 1 having four catheter separation slots 2 as an example.

[0044] Specifically, such as Figure 1 and 3 As shown, the bottom surface of the operating table 1 is equipped with two parallel stoppers 11. Each stopper 11 has a sliding groove for slidingly engaging a height adjustment rod 42. The cross-section of the two sliding grooves is a concave plane. During use, the position of the operating table 1 can be adjusted to an optimal operating position that does not obstruct the puncture site, facilitating subsequent femoral artery puncture interventional procedures.

[0045] Among them, a plurality of linearly arranged through holes are provided in the horizontal direction of the sliding groove side of the limit block 11, and correspondingly, a plurality of linearly arranged threaded holes are provided on the side where the height adjustment rod 42 contacts the limit block 11; after adjusting the position of the operating table 1, the operating table 1 can be fixed to the height adjustment rod 42 by passing the bolts through the limit block 11 and the height adjustment rod 42 in turn to prevent the operating table 1 from being displaced during the operation.

[0046] like Figure 2As shown, the height adjustment rod 42 is a π-shaped structure, including a cross bar and two longitudinal rods respectively arranged at the ends of the cross bar. The cross bar of the height adjustment rod 42 is slidably connected to the sliding groove set in the limit block 11, and the longitudinal rod of the height adjustment rod 42 is inserted into the fixed tube 41; wherein, the longitudinal rod of the height adjustment rod 42 has a plurality of threaded holes arranged at equal intervals in the vertical direction, so that the fixing bolt 43 can be threadedly connected with the longitudinal rod of the height adjustment rod 42 after passing through the fixed tube 41, thereby realizing the height adjustment of the height adjustment rod 42, thereby further realizing the height adjustment of the operating table 1.

[0047] The fixing tube 41 is L-shaped, with a cavity at its upper end for receiving the height adjustment rod 42 and a lower end fixedly connected to the base plate 3. A through hole is provided on the side of the fixing tube 41 to allow a fixing bolt 43 to pass through and then be threadedly connected to a threaded hole on the height adjustment rod 42. In practice, a fixing tube 41 is provided at each of the four corners of the base plate 3.

[0048] like Figure 3 As shown, the base plate 3 is arranged below the operating table 1, and the base plate 3 is connected to the operating table 1 through the bracket 4, so that a movable cavity is formed between the operating table 1 and the base plate 3, so that the operating table mattress and the patient's legs can pass through, so that the operating table 1 is located above the patient's legs, and the catheters used in the operation are placed one by one in the catheter separation groove 2 to prevent the catheters from being messy and confused.

[0049] like Figure 4 and 5 As shown, a limiting plate 6 is further provided in the catheter separation groove 2 , and the limiting plate 6 is used to further increase the friction between the catheter and the catheter separation groove 2 to prevent the catheter from falling.

[0050] Specifically, the retaining plate 6 is a resilient curved plate with an opening on its side. During use, medical personnel can manually open the opening of the curved plate and then place the catheter into the opening of the retaining plate 6. The retaining plate 6 then returns to its natural position to enclose the catheter, further preventing the catheter from falling out of the catheter separation slot 2 and improving the stability of the catheter. It should be noted that the embodiments of the present invention do not limit the method of fixing the retaining plate 6 within the catheter separation slot 2. For example, it can be connected by gluing.

[0051] The limiting plate 6 is made of silicone or rubber.

[0052] The operating steps of the auxiliary device for femoral artery access interventional surgery provided in this embodiment are as follows:

[0053] Step 1: Place the bottom plate 3 between the operating table mattress and the operating table bed board, with the bottom plate 3 located below the patient's thighs;

[0054] Step 2: After the patient lies on the mattress of the interventional operating table, the height adjustment rod 42 is inserted into the cavity of the fixing tube 41, and the height of the height adjustment rod 42 is adjusted according to the height of the patient's thigh. The height adjustment rod 42 is then fixed to the fixing tube 41 using the fixing bolt 43;

[0055] Step 3: Slide the operating table 1 to adjust its position so that it is located at a position that does not cover the puncture point and is convenient for the doctor to operate;

[0056] Step 4: Tighten the bolts provided at the bottom of the limit block 11 to fix the position of the operating table 1 so as to facilitate subsequent femoral artery puncture interventional operation.

The height adjustment rod 42 is then fixed to the fixing tube 41 using the fixing bolt 43;

[0061] Step 3: Slide the operating table 1 to adjust its position so that it is located at a position that does not cover the puncture point and is convenient for the doctor to operate;

[0062] Step 4: Tighten the screws provided at the bottom of the limit block 11 to fix the position of the operating table 1 so as to facilitate subsequent femoral artery puncture interventional operation;

[0063] Step 5: Perform femoral artery puncture interventional surgery; during the operation, place the catheter, guidewire, balloon dilatation catheter, intravascular stent and other instruments used in the catheter separation slot 2 for easy identification, reducing the risk of confusing the access during the operation;

[0064] In this step, the catheter can be further fixed in the catheter separation groove 2 by using an adhesive structure such as medical tape to prevent the catheter from falling.
