Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a novel postoperative examination care bracket. Background Technology

[0002] Postoperative breast cancer patients require regular wound checkups and breast palpation / ultrasound imaging. Currently, in clinical settings, patients are often seated or semi-recumbent, requiring them to actively raise their arms and adjust their chest posture to fully expose the examination area. However, since the postoperative chest wound has not yet healed, actively adjusting posture can easily pull on the wound, causing severe pain, and even leading to wound tearing and bleeding, seriously affecting the postoperative recovery process.

[0003] Meanwhile, existing simple support brackets in clinical settings can only provide fixed support at a single height, failing to precisely adjust the support position and angle according to different patient body shapes and examination sites. This results in extremely poor support adaptability, failing to provide stable, non-traction-free flexible support for the patient's chest. This can easily cause strong discomfort to patients during examinations and also limits the convenience of the doctor's examination procedures, thus affecting the accuracy of the results. Furthermore, the height adjustment structure of existing brackets lacks an anti-accidental activation limit design, making them prone to accidental sliding and locking failure after adjustment, posing significant safety hazards in clinical use.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention constructs a multi-dimensional, fully free adjustment system through the coordinated design of the Z-axis support adjustment component, the propulsion adjustment component, and the fine-tuning bracket component. It can realize all-round adjustment of bracket support height, forward and backward propulsion distance, lateral spacing, axial support angle, and tilt angle. It can adapt to the physiological characteristics of patients with different body types and the exposure needs of different examination sites. The examination area can be accurately exposed without the patient having to adjust their chest posture, avoiding postoperative wound traction, effectively reducing the patient's pain during the examination process, ensuring postoperative recovery, and greatly improving the convenience of doctors' examination operations.

[0016] 2. This invention, through the design of the anti-accidental touch limiting power component, adds a lockable limiting engagement structure and a magnetic linkage locking rod to the height adjustment power transmission path of the Z-axis support adjustment component. This not only enables precise micro-adjustment of the height through gear-bevel gear transmission, but also achieves primary locking of the transmission structure through the engagement of the locking wheel and the limiting locking groove.

[0017] 3. This invention utilizes the structural design of the fine-tuning bracket assembly, employing a sliding linkage table within the transverse guide frame to achieve rapid adjustment of the left and right lateral spacing. This, combined with a self-locking damping rotating shaft, allows for adjustment and self-locking of the axial support angle of the contact plate. Simultaneously, the linkage structure of the push screw, parallel moving plate, and support rod allows for precise adjustment of the contact plate's tilt support angle, providing flexible and adaptive support for the patient's chest. Furthermore, the contact plate surface is secured with a disposable medical silicone contact film attached via Velcro, ensuring sterility and hygiene for clinical use, preventing cross-infection, and enhancing patient comfort through the flexible contact of the silicone material, avoiding pressure on the postoperative wound from rigid supports.

[0018] 4. This invention utilizes a sprocket, gear, and rack transmission design in the adjustment component. Rotating the second actuating wheel drives the linkage gear set to rotate stably via the transmission sprocket assembly. This, in turn, drives the traveling support frame through the linkage rack to smoothly adjust the forward and backward propulsion distance. Combined with the guidance and support of the auxiliary guide wheel, this ensures that the propulsion process is smooth and without jamming or deviation. It can precisely control the distance between the support and the patient's chest, further improving the support adaptability and ease of operation. Attached Figure Description

The bottom end of the bevel gear transmission shaft 31616 extends to the inner side of the positioning mounting frame 3161 and meshes with the driving bevel gear 31615 to form a reversing transmission structure, which converts the horizontal rotation into the vertical rotation.

[0028] A linkage locking rod 3168 is rotatably connected to the outer side of the central shaft 3167 via a bearing. The linkage locking rod 3168 can rotate around the central shaft 3167.

When not in use, the contact film is sealed in a sterile packaging bag. When in use, it can be opened and replaced. One film per person avoids cross-infection. At the same time, the medical-grade silicone material can improve the patient's comfort during contact and avoid the hard structure from compressing the postoperative wound.

[0035] Working principle When a patient undergoes a post-mastrectomy examination, she should first sit on the examination chair 2 and adjust it to a suitable tilt angle to ensure she is in a comfortable semi-recumbent position. Then, according to the patient's body type and examination needs, the nursing support body 3 should be adjusted sequentially. The specific adjustment steps and working principle are as follows: Support height adjustment: First, rotate the linkage locking rod 3168 downward around the central axis 3167 to make the locking wheel 31610 disengage from the limiting locking groove 3166 of the limiting mating wheel 3165, thereby releasing the locking of the mounting shaft 3162. After the linkage locking rod 3168 rotates downward, it engages with the rotating magnetic suction slot 31611, completing the first limiting lock within the rotating magnetic suction slot 31611. At this time, the locking pin is inserted into the coaxially aligned first locking hole 3169 and second locking hole 31612 to complete the second limiting lock, achieving double anti-accidental locking and avoiding accidental activation during height adjustment, which would cause the linkage locking rod 3168 to reset, leading to unsafe situations such as emergency stop or other circumstances. Then, the first actuating wheel 3163 is rotated, which drives the mounting shaft 3162 to rotate synchronously. Through the meshing transmission of the first gear 3164 and the second gear 31614, the driven shaft 31613 and the driving bevel gear 31615 are driven to rotate. Then, through the meshing reversal of the driving bevel gear 31615 and the bevel gear transmission shaft 31616, the threaded rod 318 is driven to rotate synchronously. When the threaded rod 318 rotates, the transmission block 319 is driven to rise and fall along the threaded rod 318 through the threaded transmission, which in turn drives the linkage frame 314 to rise and fall synchronously along the first guide frame 312, thereby realizing the adjustment of the support height of the fine-tuning bracket assembly 33. After adjusting to the appropriate height, the limit locks are released one by one, and the linkage lock rod 3168 is rotated in the opposite direction, so that the locking wheel 31610 is engaged in the limit lock groove 3166 at the corresponding position, thereby completing the re-locking after adjustment. With the self-locking of the thread, a secondary anti-accidental locking is achieved after the height adjustment, which greatly improves the safety of the device.

[0036] Forward and backward movement distance adjustment: Rotating the second actuating wheel 323 drives the active sprocket shaft of the transmission sprocket assembly 324 to rotate synchronously, which drives the driven sprocket shaft to rotate through the transmission chain, and then drives the linkage gear set 325 to rotate through the transmission gear on the outside of the driven sprocket shaft; the linkage gear set 325 meshes with the linkage rack 328 to drive the linkage rack 328 and the traveling support frame 327 to move smoothly back and forth along the auxiliary guide wheel 326, so as to achieve precise adjustment of the distance between the fine-tuning bracket assembly 33 and the patient's chest. After the adjustment is completed, stop rotating the second actuating wheel 323. For safer use and more stable restriction, an anti-accidental touch limit power component 316 can also be added to the position of the second toggle wheel 323 to prevent displacement of the traveling frame 327 due to force.

[0037] Lateral Spacing and Angle Adjustment: Push the linkage slide 332 to slide left and right along the T-shaped guide groove of the lateral guide frame 331 to adjust the lateral spacing between the two sets of contact plates 335 to match the spacing of the patient's bilateral breasts; rotate the mating plate 333 to adjust the axial support angle of the mating plate 333 through the self-locking damping shaft to match the physiological curve of the patient's chest. After adjustment, the self-locking damping shaft automatically locks the adjustment; rotate the push screw 336 to drive the parallel moving plate 338 to move horizontally along the stroke guide groove 337 through the threaded transmission, and then drive the support link 3310 to swing through the linkage shaft 339. The support link 3310 pushes the contact plate 335 to rotate around the shaft of the mating plate 333, realizing the precise adjustment of the tilt support angle of the contact plate 335, so that the contact plate 335 completely fits the patient's chest, providing flexible support for the patient's chest without traction, and fully exposing the examination area without the patient having to adjust their posture.
