Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a sterile protective cover for a multifunctional microsurgical chair armrest. Background Technology

[0002] Microsurgery requires surgeons to operate instruments with both hands, their arms hanging limply. The arm muscles, lacking support, remain tense for extended periods, easily leading to fatigue and soreness, and severely impacting surgical precision – a significant problem in today's complex microsurgeries. To address this, a microsurgical chair armrest has been developed to provide support for the surgeon and reduce intraoperative fatigue.

[0003] Existing multifunctional microsurgical chair armrests require sterile cleaning of the device surface before use, resulting in a significant amount of time spent cleaning before each surgery, affecting usability and thus lacking practicality. Utility Model Content

Detailed Implementation

[0014] 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.

[0015] Example 1 See Figure 1-4 A multifunctional microsurgical chair armrest sterile protective cover includes a main component 1; the main component 1 includes a support rod 11, the top of which is fixedly connected to a bracket 12; a protective component 2 is provided on the support rod 11, the protective component 2 includes: a box body 21, disposed on the outer wall of the support rod 11; a sliding rod 22, fixedly connected to the inner wall of the box body 21; a bidirectional threaded rod 23, penetrating the box body 21 and rotatably connected to the box body 21; two movable plates 24, threadedly connected to the outer wall of the bidirectional threaded rod 23 and slidably connected to the outer wall of the sliding rod 22; fixed plates 25, each of the two movable plates 24 having a fixed plate 25 on its opposite side; a protective cover 26, disposed on the bracket 12; anti-slip pads 4 are fixedly connected to the opposite sides of the two fixed plates 25; bolts 5 are provided on the opposite sides of the two fixed plates 25.

[0016] When ready for use, the operator installs the support rod 11 in the designated position to fix the bracket 12. Then, the operator puts the protective cover 26 on the bracket 12 and places the bottom between the two fixed plates 25. The operator then manually turns the double-threaded rod 23, causing the double-threaded rod 23 to move the two moving plates 24 simultaneously. Under the limit of the sliding rod 22, the two moving plates 24 move closer to each other, thereby moving the two fixed plates 25 closer to each other and clamping the bottom of the protective cover 26. After use, simply remove and replace the protective cover 26, thus improving the practicality of the device. The anti-slip pads 4 on the opposite side of the fixed plates 25, after direct contact with the protective cover 26, can increase the friction between the protective cover 26 and the device, thereby preventing the protective cover 26 from slipping due to pulling, thus improving the stability of the device. The operator can unscrew the bolts 5 on the fixed plates 25 by hand to remove the fixation between the fixed plates 25 and the moving plates 24, thus facilitating the replacement or maintenance of the fixed plates 25.

[0017] Example 2 See Figure 1-4 Based on Embodiment 1, a disassembly function has been added; The support rod 11 is provided with a disassembly assembly 3, which includes: a fixing block 31, fixedly connected to the bottom of the box 21; a servo motor 32, fixedly connected to the front surface of the fixing block 31; a threaded rod 33, fixedly connected to the output end of the servo motor 32 and rotatably connected to the inside of the fixing block 31; a limiting block 34, threadedly connected to the outer wall of the threaded rod 33, slidably connected to the inside of the fixing block 31, and inserted into the inside of the support rod 11; a positioning plate 7 is fixedly connected to the outer wall of the support rod 11 and slidably connected to the inside of the fixing block 31; and handwheels 6 are fixedly connected to both ends of the bidirectional threaded rod 23.

[0018] After use, the operator turns on the servo motor 32 on the fixed block 31, causing the servo motor 32 to drive the threaded rod 33 to rotate. This causes the threaded rod 33 to move the limiting block 34 out of the limiting groove on the support rod 11, thus canceling the connection between the two. Subsequently, the operator can completely remove the protective component 2 and the disassembly component 3 for easy maintenance or replacement, improving the practicality of the device. When the positioning plate 7 slides inside the fixed block 31, it can maintain balance between the limiting block 34 and the limiting groove on the support rod 11, making it easy to insert into the limiting groove on the support rod 11. The operator can drive the bidirectional threaded rod 23 to rotate simultaneously by turning the handwheel 6, avoiding the inconvenience of the operator directly turning the handwheel 6, thus improving the convenience of the device.

[0019] 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.
