Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an arm support for an eyeglass assistor. Background Technology

[0002] In laparoscopic surgery, the laparoscopic assistant (also known as the assistant) plays a crucial role. The laparoscopic assistant needs to work closely with the surgeon to adjust the camera angle and position in a timely manner according to the actual operation needs, providing a clear field of vision for the operation. At the same time, in some surgical operations that require greater flexibility, the laparoscopic assistant may also be required to operate additional laparoscopic instruments, such as sutures or cutters, to complete specific operations. Laparoscopic surgery, as a modern minimally invasive surgical technique, is widely used in clinical practice due to its advantages such as small trauma and rapid recovery. However, during this procedure, the assistant (i.e., the laparoscope holder) usually needs to hold the laparoscope for a long time to ensure a clear view of the surgical field. This prolonged holding action not only increases the psychological pressure on the operator but may also lead to occupational diseases such as muscle fatigue and joint pain in the laparoscope holder. Especially during long and complex surgeries, the surgeon's operation is delicate and the demand for a clear view is even more stringent, which places higher demands on the assistant's operation and increases their physical exertion and psychological burden. In view of this, the present invention solves the above-mentioned technical problems by proposing an arm support for a mirror-adjusting assistant. Utility Model Content

[0003] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for an arm support table for a surgical endoscope assistant. This device uses a rotating knob to drive components such as threaded rod I, threaded rod II, two rotating shafts, lead screw II, and threaded rod III to adjust and fix the fixing plate, main arm, and auxiliary arm in different directions, adapting to various needs during surgery. Specifically, in use, the N-shaped fixing plate is first snapped onto the operating table frame. Rotating the knob causes threaded rod III to move the pressure block, thus fixing the fixing plate. The main arm is connected to the inner cavity of the fixing plate via a sliding block. Rotating the knob and lead screw II drives the main arm and sliding block to slide along the inner cavity of the fixing plate, adjusting the position of the main arm. Further, rotating the knob drives bevel gear I, which in turn rotates bevel gear II and lead screw I, driving the telescopic arms within the main and auxiliary arms to extend and retract. Adjust the extension length of the main arm and auxiliary arm. When adjusting the angle of the auxiliary arm, rotate the knob to create a gap between the auxiliary arm and the main arm. Then rotate the auxiliary arm and rotate the knob again to drive the threaded rod II to fix the auxiliary arm. Similarly, rotate the knob to create a gap between the main arm and the rotating disk. Rotate the main arm and rotate the knob again to drive the threaded rod I to fix the main arm, thus completing the adjustment of the main arm angle. The arc-shaped groove on the top of the support block is designed to support the assistant's forearm and elbow, and is equipped with a soft anti-slip pad to improve comfort. Multiple wire clamps in the inner cavity of the mounting block ensure the fixation and guidance of surgical instrument wires by manual sliding, keeping the surgical area clean. The entire device coordinates the interaction of multiple mechanical parts through rotating the knob, realizing multi-functional and multi-angle free adjustment and fixation to meet the various usage needs of the operating table support components and auxiliary instruments during surgery.

[0017] 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.

[0018] Please see Figures 1-6As shown, an arm support for a glasses-adjusting assistant includes a folding arm and a fixed plate 1. The folding arm consists of a main arm 2 and a secondary arm 201. A sliding block 202 is slidably connected to the inner cavity of the fixed plate 1. A connecting plate 203 is fixedly connected to the top of the sliding block 202. A rotating plate 204 is rotatably connected to the inner cavity of the connecting plate 203. A threaded rod I205 is threadedly connected to the inner cavity of the rotating plate 204. The threaded rod I205 is connected to the main arm 2 via a bearing. Telescopic arms I206 and II207 are slidably connected to the inner cavities of the main arm 2 and the secondary arm 201, respectively. A threaded rod II is threadedly connected to the inner cavity of the secondary arm 201. 208. Threaded rod II 208 is connected to telescopic arm I 206 via bearings. Adjustment components are rotatably connected to the inner cavities of both the main arm 2 and the auxiliary arm 201. Each adjustment component includes two lead screws I 3, which are rotatably connected to the inner cavities of the main arm 2 and the auxiliary arm 201, respectively. Bevel gears I 301 are fixedly connected to the surfaces of both lead screws I 3. Two rotating shafts 302 are rotatably connected to the inner cavities of both the main arm 2 and the auxiliary arm 201. Bevel gears II 303 are fixedly connected to one end of each rotating shaft 302. The surfaces of the two lead screws I 3 are threadedly connected to the inner cavities of telescopic arms I 206 and II 207, respectively. The top of the telescopic arm II207 is fixedly connected to a support block 4. The top of the support block 4 has an arc-shaped groove 401. A soft anti-slip pad 402 is installed inside the arc-shaped groove 401. The soft anti-slip pad 402 is 5mm to 10mm thick and has an anti-slip texture on its surface. The shape of the arc-shaped groove 401 conforms to the shape of the human forearm and elbow. A lead screw II5 is rotatably connected to the inner cavity of the fixing plate 1. The lead screw II5 is connected to the fixing plate 1 via a bearing. The surface of the lead screw II5 is threadedly connected to the inner cavity of the sliding block 202. Two threaded rods III501 are threadedly connected inside the fixing plate 1. Two threaded rods III501 are fixedly connected to one end of a pressure block 502. The fixed plate 1 is N-shaped. A mounting block 6 is fixedly connected to one side of the main arm 2. A wire clamp 601 is slidably connected to the inner cavity of the mounting block 6. There are 3 to 5 wire clamps 601, and the distribution spacing is 50mm to 100mm. A pin hole 7 is opened at one end of the connecting plate 203 and the rotating plate 204. A pin 701 is slidably connected to the inner cavity of the pin hole 7. A knob 8 is fixedly connected to one end of the threaded rod I205, the threaded rod II208, the two rotating shafts 302, the lead screw II5 and the threaded rod III501.

[0019] When in use, first attach the N-shaped fixing plate 1 to the operating table frame, then rotate the knob 8 to make the knob 8 drive the two threaded rods III501 to rotate. The two threaded rods III501 drive the pressure block 502 to move, so that one end of the pressure block 502 contacts the surface of the operating table frame, generating a large friction force, thereby fixing the fixing plate 1. Since the folding arm is composed of a main arm 2 and a secondary arm 201, the main arm 2 is connected to the inner cavity of the fixed plate 1 by a sliding connection. When it is necessary to adjust the position of the main arm 2, rotate the knob 8 to make the knob 8 drive the lead screw II5 to rotate. The rotation of the lead screw II5 drives the sliding block 202 and the rotating disk 204 to move. The movement of the rotating disk 204 then moves the main arm 2. When it is necessary to adjust the telescopic length of the main arm 2 and the auxiliary arm 201, the knob 8 is rotated, which drives the bevel gear I301 to rotate through the rotating shaft 302. The rotation of the bevel gear I301 drives the bevel gear II303 and the lead screw I3 to rotate. The rotation of the lead screw I3 drives the telescopic arm I206 and the telescopic arm II207 in the inner cavity of the main arm 2 and the auxiliary arm 201 to extend and retract. Since there are two rotating shafts 302, when the lens-holding hand holds the lens with its left hand, the right hand can be used to rotate the right knob 8, which drives the bevel gear I301 to rotate via the rotating shaft 302. The rotation of bevel gear I301 then drives the bevel gear II303 and the lead screw I3 to rotate. The rotation of lead screw I3 then drives the telescopic arms I206 and II207 in the inner cavity of the main arm 2 and the auxiliary arm 201 to extend and retract. Conversely, when the lens-holding hand holds the lens with its right hand, the left hand can be used to rotate the left knob 8, which drives the lead screw I3 to rotate and drive the telescopic arms I206 and II207 in the inner cavity of the main arm 2 and the auxiliary arm 201 to extend and retract. When it is necessary to adjust the angle of the auxiliary arm 201, rotate the knob 8 to make the threaded rod II 208 rotate, so that a gap is created between the auxiliary arm 201 and the main arm 2. Since the threaded rod II 208 is connected to the auxiliary arm 201 through the bearing, the auxiliary arm 201 can be rotated to adjust the angle. After the adjustment is completed, rotate the knob 8 again to make the threaded rod II 208 rotate, so that the auxiliary arm 201 contacts the surface of the main arm 2, generating a large friction force to fix the auxiliary arm 201. When it is necessary to adjust the angle of the main boom 2, rotate the knob 8 to make the threaded rod I205 rotate, so that a gap is created between the main boom 2 and the connecting plate 203. Since the threaded rod I205 is connected to the main boom 2 through the bearing, the main boom 2 can be rotated to adjust the angle. After the adjustment is completed, rotate the knob 8 again to make the threaded rod I205 rotate, so that the main boom 2 contacts the surface of the connecting plate 203, generating a large friction force to fix the main boom 2. Since the number of pin holes 7 at one end of the connecting plate 203 is eight and the number of pin holes 7 at one end of the rotating plate 204 is one, when the main arm 2 needs to rotate, the pin 701 is pulled out. At this time, the main arm 2 can rotate 360 ​​degrees through the rotating plate 204. The rotation of the main arm 2 can drive the auxiliary arm 201 to rotate. When the main arm 2 does not need to rotate, the pin 701 is inserted back into the inner cavity of the pin hole 7. At this time, the pin 701 will limit the rotation of the rotating plate 204 and prevent the rotating plate 204 from rotating. The top of the support block 4 is provided with an arc-shaped groove 401. The arc-shaped groove 401 is ergonomically designed and is mainly used to support the assistant's forearm and elbow. The inner cavity of the arc-shaped groove 401 is provided with a soft anti-slip pad 402. The anti-slip pad is made of soft material and has anti-slip properties, which is intended to improve the assistant's comfort and prevent slipping. The inner cavity of the mounting block 6 is equipped with three wire clips 601. The positions of the three wire clips 601 can be adjusted by manual sliding. They are mainly used to fix and guide the wires of surgical instruments, avoid wire clutter, and ensure the cleanliness of the surgical area. Secondly, the wire clips 601 are elastic buckles.
