Description

Technical Field

[0001] This invention relates to the field of arthroscopic surgical aids, specifically to an orthopedic arthroscopic surgical aid device. Background Technology

[0002] In the field of orthopedic arthroscopic surgery, traditional surgical procedures have many inconveniences and limitations. Previously, when fixing the arthroscope, there was a lack of specialized and effective fixation devices, typically relying on medical staff to manually support it. This not only greatly increased the workload of medical staff, but also made the arthroscope prone to shaking or displacement during surgery due to the limb movements of medical staff or even slight movements of the patient. This resulted in an unstable surgical field, affecting the accuracy and success of the surgery, and potentially prolonging the operation time and increasing surgical risks.

[0003] Traditional methods for adjusting the angle and height of the arthroscopy are cumbersome and difficult to control precisely. Without dedicated angle and height adjustment mechanisms, surgeons often rely on experience, constantly adjusting their stance or using simple auxiliary tools to try and obtain a suitable surgical field. This is not only inconvenient but also makes it difficult to guarantee achieving the ideal surgical position every time. Furthermore, there is a lack of effective means to adjust the patient's knee joint posture during surgery. The patient's natural knee joint posture may not be suitable for surgical manipulation, and traditional methods struggle to conveniently and accurately adjust the knee joint posture, which also affects the surgical outcome and efficiency. Therefore, developing an orthopedic arthroscopic surgical aid device that can solve the above problems is of significant practical importance. Summary of the Invention

[0004] In view of the deficiencies mentioned above in the background art, a technical solution for an orthopedic arthroscopic surgery auxiliary device is provided.

[0010] In the above technical solution, preferably, multiple anti-slip grooves are formed in a ring array on the inner surface of the silicone liner, and the side surfaces of the silicone liner that are close to each other are in close contact with the outer surface of the arthroscope.

[0011] In the above technical solution, preferably: the inside of the ball groove is provided with a chamber for the ball head to move, and a layer of 1mm-2mm silicone sheet is adhered to the inner surface of the chamber by an adhesive, for the ball head to move to the desired angle and then hover.

[0012] In the above technical solution, preferably: the interior of the triangular fixing plate is provided with a threaded hole for the screw to pass through and rotate, and a knob is fixedly connected to the bottom end of the screw.

[0013] In the above technical solution, preferably, the inner and outer ends of the traction rod are hinged to the sleeve and the connecting plate by means of a pivot pin.

[0014] In the above technical solution, preferably, a limiting ring is fixed at the middle section of the outer ring surface of the support foot, which is used to allow the sleeve to slide on the support foot and stop after reaching the position of the limiting ring.

[0015] In the above technical solution, preferably: a layer of silicone pad is adhered to the outer surface of the bow-shaped metal plate by an adhesive, and a layer of sterile non-woven fabric is laid on the silicone pad.

Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. In order to provide a clearer explanation and description of the technical solutions and implementation methods of the present invention, the following describes specific embodiments that implement the preferred technical solutions of the present invention.

[0029] Example 1: An orthopedic arthroscopic surgical aid device includes an arthroscope 1, an arthroscope support 2 fixedly connected to the outer ring of the arthroscope 1, a stabilizing support 3 at the bottom of the arthroscope support 2, and a joint posture maintainer at the front of the arthroscope 1. The arthroscope support 2 consists of two symmetrically mirrored clamps 2-1, with protrusions on both sides of the clamps 2-1, and screws 2-2 passing through the protrusions for tightening. A silicone liner 2-3 is fixed to the inner wall of the clamp 2-1 with adhesive. The inner surface of the silicone liner 2-3 has multiple anti-slip grooves arranged in a ring array and is in close contact with the outer ring of the arthroscope 1. A connecting post 2-4 is fixed to the lower surface of the bottom clamp 2-1, and a ball head 2-5 is fixed to the bottom end of the connecting post 2-4. A ball groove 2-6 is movably fitted on the outer surface of the ball head 2-5, and a 1.5mm silicone sheet is adhered to the inner surface of the inner cavity of the ball groove 2-6. The triangular fixing plate 3-1 of the stabilizing support 3 has a threaded hole for the screw 3-2 to pass through and rotate. The top of the screw 3-2 is rotatably connected to the bottom surface of the ball groove 2-6. The bottom end is fixed with a knob 3-3. The outer surface of the triangular fixing plate 3-1 is hinged with three support feet 3-5 through a shaft pin. A limiting ring is fixed in the middle of the outer surface of the support feet 3-5. The support feet 3-5 are fitted with movable sleeves 3-4. The sleeves 3-4 are hinged with a shaft pin to a pull rod 3-6. The pull rods 3-6 are brought together and one end is hinged to a connecting plate 3-7. The bow-shaped metal plate 4 of the joint posture maintainer is placed under the knee joint, with a silicone pad adhered to its outer surface. A sterile non-woven fabric is laid on the silicone pad. A strong magnet block 6 is fixed to the bottom end of the bow-shaped metal plate 4. A rubber plate 5 is connected to the bottom surface of the strong magnet block 6. A magnet strip is embedded and fixed on the upper surface of the rubber plate 5 and magnetically attracted to the strong magnet block 6. Two lead screws 7 are rotatably connected to the front and rear sides of the inner side of the bow-shaped metal plate 4. The outer ring surface of the lead screw 7 is threaded and the thread direction is mirror symmetrical. The sections of the lead screw 7 that are close to each other are screwed with an internal threaded sleeve 8. The internal threaded sleeve 8 is provided with threads that are compatible with the outer ring threads of the lead screw 7.

[0030] Example 2: An orthopedic arthroscopic surgery auxiliary device. The connection between the arthroscope 1 and the arthroscope support 2 is the same as in Example 1. The anti-slip groove on the inner side of the silicone liner 2-3 of the arthroscope support 2 is slightly shallower, and a 1mm silicone sheet is adhered to the inner surface of the ball groove 2-6. In the stabilizing support 3, the threaded connection structure between the screw 3-2 and the triangular fixation plate 3-1 remains unchanged. The position of the limiting ring on the support foot 3-5 is slightly adjusted. The connection method of the sleeve 3-4, the traction rod 3-6, and the connecting plate 3-7 is the same as in Example 1. The shape of the bow-shaped metal plate 4 of the joint posture maintainer is slightly adjusted according to the characteristics of the patient's knee joint. The thickness of its outer silicone pad is increased, and the sterile non-woven fabric is replaced with a softer material. The connection method between the strong magnet 6 and the rubber plate 5 through magnetic strip adsorption remains unchanged. The threaded adaptation structure of the lead screw 7 and the internal threaded sleeve 8 is the same as in Example 1.

[0031] Example 3: An orthopedic arthroscopic surgery auxiliary device. In the arthroscopic support 2 of the outer ring of the arthroscope 1, the fastening bolt 2-2 of the clamp 2-1 adopts a more easy-to-operate design; the number of anti-slip grooves on the inner side of the silicone liner 2-3 is increased; and a 2mm silicone sheet is adhered to the inner surface of the ball groove 2-6. The triangular fixing plate 3-1 of the stabilizing support 3 is made of a more robust material; the knob 3-3 of the screw 3-2 is enlarged for easier operation; and the hinge structure of the sleeve 3-4 of the support foot 3-5, the traction rod 3-6, and the connecting plate 3-7 is more stable. The surface treatment of the arc-shaped metal plate 4 of the joint posture maintainer is smoother; the outer silicone pad is replaced with a material with better elasticity; the strong magnet block 6 and the magnetic strip of the rubber plate 5 are more tightly attracted; and the threaded fit between the lead screw 7 and the internal threaded sleeve 8 is more precise.

[0032] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: The arthroscope 1 is placed between the two mirror-symmetrical clamps 2-1 of the arthroscope support 2. By tightening the fastening bolts 2-2 between the protrusions on both sides of the clamp 2-1, the clamp 2-1 is gradually tightened, firmly fixing the arthroscope 1. At this time, the silicone liner 2-3, fixed with adhesive to the inner wall of the clamp 2-1, is in close contact with the outer ring of the arthroscope 1. The multiple anti-slip grooves arranged in a ring array on the inner surface of the silicone liner 2-3 increase friction and prevent the arthroscope 1 from sliding. Next, the stabilizing support 3 is placed in a suitable position, and the connecting column 2 is fixed to the lower surface of the clamp 2-1 at the bottom of the arthroscope support 2. -4 The ball head 2-5 at the bottom end is placed into the cavity inside the ball groove 2-6 of the stabilizing support 3. The 1mm-2mm silicone sheet attached to the inner surface of the ball groove 2-6 allows the ball head 2-5 to move to the desired angle and then suspend. Then, the height of the stabilizing support 3 is adjusted according to the surgical needs. By rotating the knob 3-3 on the bottom end of the screw 3-2 that passes through the threaded hole inside the triangular fixation plate 3-1, the screw 3-2 is rotated and raised or lowered within the threaded hole, thereby adjusting the height of the ball groove 2-6 and the arthroscope bracket 2 and arthroscope 1 above it. At the same time, the support stability of the stabilizing support 3 can be adjusted. The three support legs 3-5 on the outer surface of the triangular fixation plate 3-1, which are hinged by the shaft pin, are unfolded. A limiting ring fixed at the middle of the outer surface of the support foot 3-5 restricts the sliding position of the sleeve 3-4, which is fitted onto the support foot 3-5. When the sleeve 3-4 slides to the appropriate position, a stable support structure is formed by the traction rod 3-6, which is hinged close to the sleeve 3-4, and the connecting plate 3-7, which is hinged at one end of the traction rod 3-6. This allows the stable support 3 to firmly support the arthroscope 1. Then, the arc-shaped metal plate 4 of the joint posture maintainer is placed under the patient's knee joint. The silicone pad adhered to the outer surface of the arc-shaped metal plate 4 with adhesive increases patient comfort, and the sterile non-woven fabric laid on the silicone pad ensures hygiene. The arrangement is adjusted according to the specific posture of the patient's knee joint. To achieve the desired effect, the two lead screws 7 connected to the front and rear sides of the inner side of the bow-shaped metal plate 4 are rotated. Since the threads on the outer surface of the lead screws 7 are mirror-symmetrical, and the internal threaded sleeves 8 on the sections of the lead screws 7 that are close to each other have threads that match the threads on the outer surface of the lead screws 7, when the lead screws 7 are rotated, the internal threaded sleeves 8 will move along the lead screws 7, thereby adjusting the posture of the knee joint. The strong magnet block 6 fixed at the bottom end of the bow-shaped metal plate 4 is connected to the rubber plate 5 connected to the bottom surface by magnetic strips embedded and fixed on the upper surface of the rubber plate 5, which can ensure the stability of the bow-shaped metal plate 4. At this point, the installation and adjustment of the orthopedic arthroscopic surgery auxiliary device are completed, and the arthroscopic surgery operation can begin.
