Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a special fixator for lymphangiography embolization. Background Technology

[0002] Lymphangiography is performed by puncturing the lymphatic vessels on the dorsum of the foot; however, direct puncture of the inguinal lymph nodes followed by embolization of the leaking site has become a widely accepted treatment method in this situation. Although lymphoembolization is primarily used to treat chylothorax, it has also been attempted to treat chylous ascites. The use of appropriate contrast agents and obtaining clear lymphangiography are crucial for the success of this procedure. During lymphangiographic embolization, the puncture site needs to be fixed with a fixator.

[0003] Existing fixators typically require puncture with a needle after fixation. During puncture, the angle of the needle needs to be changed. Since the fixator cannot fix the changed angle of the needle, the stability of the needle decreases, affecting the lymphangiography embolization procedure and increasing its failure rate. In severe cases, it can lead to the failure of the lymphangiography embolization procedure. Therefore, we need to propose a dedicated fixator for lymphangiography embolization. Utility Model Content

[0004] The purpose of this invention is to provide a dedicated fixator for lymphangiography embolization. In use, a transparent plastic sheet is applied to the patient's thigh skin, and a puncture needle is inserted into the groove and fixed by the fixing structure. The needle is then used to puncture the patient. The support seat is then moved to adjust the distance between it and the fixator base. Subsequently, a positioning plate, through an adjustment structure, positions the adjusted support seat, changing the angle between the fixator base and the support seat. This allows the fixator to fix the puncture needle at the changed angle, improving stability after the needle angle change, reducing the impact on the lymphangiography embolization procedure, and lowering the failure rate of the procedure, thus solving the problems mentioned in the background art.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a special fixator for lymphangiography embolization, including a fixator base 1, a support seat 4 rotatably connected to one end of the fixator base 1, a groove 5 for placing a puncture needle on the upper surface of the support seat 4, a fixing structure 2 for fixing the puncture needle on the outer side wall of the support seat 4, a support plate 6 rotatably connected to the outer side wall of the fixator base 1 via a rotating shaft, the support plate 6 is arc-shaped, an adjustment structure 7 for adjusting the position of the support plate 6 on the support seat 4 is provided on the surface of the support plate 6, a transparent plastic sheet 3 is provided on the lower surface of the fixator base 1, and a connection structure 8 for quick connection with the fixator base 1 is provided at the top of the transparent plastic sheet 3;

[0025] Furthermore, such as Figure 1 As shown, medical staff fix the transparent plastic sheet 3 to the patient's thigh skin, insert the puncture needle into the groove 5 and fix it through the fixing structure 2, then perform the puncture with the puncture needle, and then move the support seat 4 to adjust the distance between the support seat 4 and the fixator base 1. Then, the positioning plate positions the adjusted support seat 4 through the adjustment structure 7, so that the angle between the fixator base 1 and the support seat 4 changes. Finally, the fixator base 1 is connected to the transparent plastic sheet 3 through the connecting structure 8, so that the fixator can fix the changed angle position of the puncture needle, improve the stability after the puncture needle angle is changed, reduce the impact on the lymphangiography embolization procedure, and reduce the failure rate of the lymphangiography embolization procedure.

[0026] Specifically, the fixing structure 2 includes a threaded hole 21, which is formed on the outer surface of the support base 4. One end of the threaded hole 21 is connected to the inner cavity of the groove 5. A locking screw is threadedly connected to the inner cavity of the threaded hole 21. A button block 23 is fixedly connected to one end of the locking screw. By cooperating with the threaded hole 21 and the locking screw, turning the button block 23 can drive the locking screw to rotate, so that the locking screw rotates and moves the inner cavity of the groove 5 to fit against the surface of the puncture needle, thereby fixing the puncture needle.

[0027] Preferred, such as Figure 2 As shown, several sets of threaded holes 21 are provided, and these sets of threaded holes 21 are evenly distributed on the surface of the support base 4. By providing several sets of threaded holes 21, several sets of locking screws can fix the puncture needle at multiple points, thereby improving the stability of the puncture needle in the groove 5.

[0028] In addition, the button 23 is cylindrical and has anti-slip texture on its outer surface. The button 23 is designed to make it easy for medical staff to turn it. The anti-slip texture increases the friction between the medical staff's hands and the button 23, reducing the occurrence of slippage.

[0029] In a further preferred embodiment, such as Figure 3 As shown, the adjustment structure 7 includes a support hole 71 and a positioning hole 72. The support hole 71 is opened on the surface of the support plate 6, and a metal pin 73 is slidably inserted into the inner cavity of the support hole 71. The positioning hole 72 is opened on the outer wall of the support base 4, and several sets of positioning holes 72 are provided. The several sets of positioning holes 72 are evenly distributed on the outer surface of the support base 4. The metal pin 73 is inserted into the inner cavity of the support hole 71 and extends into the positioning hole 72, so that the position of the support plate 6 on the support base 4 is positioned. The support plate 6 supports the position of the support base 4 after adjustment. By changing the position of the support hole 71 on different positioning holes 72, the support plate 6 can support the support base 4 at different positions after the angle is changed.

[0030] Preferably, the connecting structure 8 includes a hook and loop fastener surface 81 and a hook and loop fastener hook surface 82. The surface of the hook and loop fastener surface 81 is bonded and fixed to the surface of the hook and loop fastener hook surface 82. The hook and loop fastener surface 81 is disposed on the lower surface of the fixing base 1, and the hook and loop fastener hook surface 82 is disposed on the upper surface of the transparent plastic sheet 3. Through the arrangement of the hook and loop fastener surface 81 and the hook and loop fastener hook surface 82, the fixing device and the transparent plastic sheet 3 can be quickly disassembled and connected.

[0031] In addition, the end of the support base 4 away from the fixation base 1 is provided with an anti-slip groove 9. Several sets of anti-slip grooves 9 are provided. By setting the anti-slip grooves 9, the friction between the support base 4 and the hands of medical staff is increased, making it easier to insert the puncture needle into the groove 5.

[0032] Furthermore, the lower surface of the transparent plastic sheet 3 is coated with adhesive, and the thickness of the adhesive coating is set to 0.1-0.5mm. By applying the adhesive coating, the transparent plastic sheet 3 can be quickly bonded to the skin of the patient's thigh.

[0033] Specifically, the length of the transparent plastic sheet 3 is greater than the length of the hook and loop fastener 81. Several sets of hook and loop fasteners 82 can be placed on the transparent plastic sheet 3. Through the setting of the transparent plastic sheet 3, several sets of fixators can be placed on one set of transparent plastic sheet 3, and several sets of fixators can fix puncture needles at different positions.

[0034] Preferably, a magnet block 10 is provided in the inner cavity of the positioning hole 72. The surface of the magnet block 10 is magnetically connected to the surface of the metal pin 73. Through the cooperation between the magnet block 10 and the metal pin 73, the stability of the metal pin 73 in the positioning hole 72 is increased, and the metal pin 73 is prevented from falling out of the positioning hole 72.

[0035] In practical use: Medical staff place the transparent plastic sheet 3 on the patient's thigh skin. The transparent plastic sheet 3 is adhered to the skin surface by the adhesive coating on the bottom. Then, the puncture needle is inserted into the groove 5. Turning the button 23 rotates the locking screw, fixing the puncture needle in place. Subsequently, the medical staff performs the puncture on the patient. After the puncture, the fixation base 1 is rotated, causing the fixation base 1 and the support base 4 to flip, changing the angle between them. The fixation base 1 is secured by Velcro. The rough surface 81 is bonded to the Velcro hook surface 82 on the transparent plastic sheet 3. After the fixation base 1 is bonded and fixed, the angle of the support plate 6 is adjusted. Finally, the metal pin 73 is inserted into the inner cavity of the support hole 71 and extends into the positioning hole 72, so that the support plate 6 supports the angle between the fixed base 1 and the support seat 4 after adjustment. This allows the fixation device to fix the angle position of the puncture needle after the angle is changed, improving the stability after the angle of the puncture needle is changed, reducing the impact on the lymphangiography embolization surgery, and reducing the failure rate of the lymphangiography embolization surgery.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
