Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an upper limb surgical auxiliary device that facilitates intraoperative fluoroscopy and debridement functions and is compatible with the operating table guide rail for fixation. It is suitable for scenarios such as orthopedics and microsurgery where frequent adjustments to the upper limb position and intraoperative imaging examinations are required. Background Technology

[0002] When a hospital performs surgery on a patient's upper limb, it first needs to clean the wound. After cleaning, the surgery is then performed. During the surgery, the upper limb needs to be examined with X-rays at any time to ensure the success of the surgery.

[0003] However, current operating tables lack a dedicated platform for supporting the upper limbs. Some hospitals use a small metal table next to the operating table to support the patient's upper limb. This metal table cannot meet the fluoroscopic requirements of X-ray or CT scanners, necessitating the movement of the patient's upper limb to accommodate these examinations, significantly impacting surgical efficiency. Furthermore, during wound cleaning of the patient's upper limb, the metal table cannot collect and discharge wastewater, potentially splashing it outside and contaminating the medical environment. Utility Model Content

[0004] The main purpose of this utility model is to provide an upper limb surgical debridement auxiliary device based on the operating table guide rail, so as to solve the problems in the prior art where the small table made of metal cannot meet the fluoroscopy requirements of X-ray or CT machines, and the small table made of metal cannot collect and discharge the sewage after cleaning the wound, which may splash the sewage to the outside and cause pollution to the medical environment.

[0005] To solve the above problems, the present invention adopts the following technical solution: an upper limb surgical debridement auxiliary device based on the fixing of the operating table guide rail, including a support frame snapped onto the guide rail on one side of the operating table, a cleaning tank fixed to the top of the support frame, and a cover plate covering the top of the cleaning tank. The cover plate is detachably connected to the cleaning tank. The support frame, the cleaning tank, and the cover plate are all made of carbon fiber.

[0006] Furthermore, two inverted U-shaped locking blocks are spaced apart on the bottom of the support frame near the guide rail, and both locking blocks are engaged with the guide rail.

[0007] Furthermore, each of the locking blocks is provided with a wing nut on one side. One end of the wing nut passes through the side wall of the locking block and moves toward the guide rail, and is screwed into the corresponding locking block.

[0008] Furthermore, the cleaning tank is a box with an open top, and a drain nozzle is connected to the side of the cleaning tank away from the operating table.

[0009] Furthermore, the bottom surface of the cleaning tank is an inclined surface that extends downward from the side near the operating table to the side near the drain outlet.

[0010] Furthermore, at least one cushion is provided inside the cleaning tank.

[0011] Furthermore, a slide is provided at the top of the cleaning tank, and the cover plate is slidably inserted into the slide.

[0012] Furthermore, the end of the cover plate away from the operating table has a through groove running vertically, and a connecting plate is fixedly installed at one end of the cleaning tank below the through groove. The connecting plate has a stop portion for preventing the cover plate from moving away from the slide.

[0013] Furthermore, the connecting plate is provided with a through hole running vertically through it. The stop part includes a stop rod that is slidably disposed in the through hole. A fixing block is fixedly disposed at the bottom end of the stop rod. The diameter of the fixing block is larger than the diameter of the through hole. The top end of the stop rod extends upward away from the connecting plate and into the through groove. A retaining ring is fixedly sleeved on the upper part of the stop rod. A first spring is sleeved on the outer side of the stop rod. The two ends of the first spring abut against the retaining ring and the connecting plate, respectively.

[0014] Furthermore, both the cleaning tank and the cover plate have arc-shaped clearance grooves on both sides in the width direction.

[0015] The beneficial effects of this invention are as follows: By using carbon fiber for the support frame, cleaning tank, and cover, X-ray examination of the upper limbs is facilitated, improving the accuracy of the test results. The cleaning tank facilitates the collection and discharge of wastewater after cleaning, preventing pollution of the medical environment. The detachable connection between the cover and the cleaning tank allows for quick switching between the various modes described above. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Please see Figures 1 to 3 As shown, an upper limb surgical debridement auxiliary device based on an operating table guide rail includes a support frame 1, a cleaning tank 2, and a cover plate 3. The support frame 1 is snapped onto a guide rail 71 on one side of the operating table 7 to support the cleaning tank 2 and the cover plate 3. Specifically, two inverted U-shaped locking blocks 11 are spaced apart on the bottom of the support frame 1 near the guide rail 71. Both locking blocks 11 are snapped onto the guide rail 71, thereby fixing the support frame 1 onto the guide rail 71. Preferably, each locking block 11 has a wing nut 4 on one side. One end of the wing nut 4 passes through the side wall of the locking block 11 and moves towards the guide rail 71, and is screwed onto the corresponding locking block 11. This allows for a more secure fixation between the support frame 1 and the guide rail 71 by rotating the wing nut 4.

[0025] The cleaning tank 2 is fixedly mounted on the top of the support frame 1 to collect wastewater after wound cleaning. In this embodiment, the support frame 1 is fixedly connected to the bottom surface of the cleaning tank 2 by multiple PEEK screws 5. By using PEEK screws 5 to connect the support frame 1 and the cleaning tank 2, the metal screws are avoided from affecting the imaging effect, thereby improving the X-ray image quality. Specifically, the cleaning tank 2 is a box with an open top. A drain nozzle 21 is connected to the side of the cleaning tank 2 away from the operating table 7 to drain the wastewater. It should be noted that the drain nozzle 21 needs to be connected to an external bucket to collect wastewater or directly to a suction device in the prior art to drain the wastewater in the cleaning tank 2. Preferably, the bottom surface of the cleaning tank 2 is an inclined surface extending downward from the side closer to the operating table 7 towards the side closer to the drain nozzle 21. In this way, the wastewater in the cleaning tank 2 can be drained more effectively by gravity.

[0026] In practice, the patient's upper limb requiring debridement is placed above the cleaning tank 2, and then the patient's upper limb is cleaned (debridement) with a cleaning solution (e.g., iodine). The cleaning tank 2 collects the wastewater after cleaning and discharges it through the drain nozzle 21. Preferably, the cleaning tank 2 is equipped with at least one cushion 24 to elevate the patient's upper limb, thus facilitating cleaning by medical personnel. In this embodiment, two cushions 24 are used, spaced apart on both sides of the length of the cleaning tank 2, to better support the patient's upper limb. It should be noted that the cushions 24 are made of plastic.

[0027] In this embodiment, the cover plate 3 is placed on top of the cleaning tank 2, and the cover plate 3 is detachably connected to the cleaning tank 2. When it is necessary to clean the patient's upper limb, the medical staff removes the cover plate 3 and places the patient's upper limb above the cleaning tank 2 for cleaning. After cleaning, the medical staff replaces the cover plate 3 at the top opening of the cleaning tank 2, and then places the patient's upper limb on the top surface of the cover plate 3 for surgery or X-ray examination. It should be noted that the support frame 1, the cleaning tank 2, and the cover plate 3 are all made of carbon fiber. This utilizes the characteristic that X-rays generated by the X-ray machine can easily penetrate carbon fiber, which is beneficial for X-ray examination of the upper limb and improves the accuracy of the test results.

[0028] Specifically, a slide 22 is provided at the top of the cleaning tank 2, and the cover plate 3 is slidably inserted into the slide 22. This allows medical personnel to easily install or remove the cover plate 3 through the cooperation of the slide 22 and the cover plate 3. Preferably, the end of the cover plate 3 away from the operating table 7 has a through groove 31 extending vertically, which is defined as a handle to facilitate the staff pulling the cover plate 3 away from the slide 22.

[0029] In this embodiment, a connecting plate 23 is fixedly installed at one end of the cleaning tank 2 below the through groove 31. The connecting plate 23 is provided with a stop 6 to prevent the cover plate 3 from moving away from the slide 22, so that the cover plate 3 is more firmly fixed to the cleaning tank 2 and to prevent the cover plate 3 from detaching from the slide 22 during the operation. Specifically, the connecting plate 23 is provided with a through hole (not shown in the figure) that runs vertically through the tank. The stop 6 includes a stop rod 61 that is slidably installed in the through hole. A fixing block 62 is fixedly installed at the bottom end of the stop rod 61. The diameter of the fixing block 62 is larger than the diameter of the through hole. The top end of the stop rod 61 extends upward away from the connecting plate 23 into the through groove 31. A retaining ring 611 is fixedly sleeved on the upper part of the stop rod 61. A first spring 63 is sleeved on the outer side of the stop rod 61. The two ends of the first spring 63 abut against the retaining ring 611 and the connecting plate 23, respectively.

[0030] It should be noted that when the cover plate 3 is inserted into place (i.e., when the cover plate 3 is located in the slide 22 and completely covers the cleaning tank 2), the top of the stop lever 61 is located in the through groove 31 and abuts against the side of the through groove 31 near the slide rail, thereby confining the cover plate 3 within the slide 22 and preventing the cover plate 3 from detaching from the slide 22. When it is necessary to remove the cover plate 3 from the slide 22, the medical staff first presses the top of the stop lever 61, causing the stop lever 61 to move downwards (at this time, the first spring 63 is compressed). When the top of the stop lever 61 is completely removed from the through groove 31, the medical staff can remove the cover plate 3 without the obstruction of the stop lever 61.

[0031] In the specific implementation of this utility model, firstly, the two inverted U-shaped locking blocks 11 on the bottom surface of the support frame 1 are inserted from top to bottom onto the outer side of the guide rail 71. Then, by rotating the wing nut 4, the support frame 1 is firmly fixed on the slide rail of the operating table 7. When it is necessary to clean the patient's upper limb, the cover plate 3 needs to be removed, and the patient's upper limb is placed on the pillow pad 24 in the cleaning tank 2. Then, the patient's upper limb is cleaned (debridement), and the wastewater after cleaning is discharged through the drain nozzle 21. When it is necessary to perform surgery on the patient's upper limb after cleaning, the medical staff re-insert the cover plate 3 into the slide rail 22 and insert the top of the stop bar 61 into the through groove 31, thereby making the cover plate 3 firmly cover the top of the cleaning tank 2. At this time, the patient's upper limb is located on the cover plate 3 to facilitate the operation. Preferably, both sides of the cleaning tank 2 and the cover plate 3 in the width direction are provided with arc-shaped clearance grooves 32 to make way for medical staff and facilitate medical staff to perform various operations on the patient's upper limb during surgery.

[0032] It should be noted that by using carbon fiber for the support frame 1, the cleaning tank 2, and the cover plate 3, the accuracy of X-ray examinations of the upper limbs can be improved. Multiple PEEK screws 5 are used to securely connect the support frame 1 to the bottom of the cleaning tank 2, avoiding X-ray artifacts caused by metal screws that could affect image clarity. The cleaning tank 2 facilitates the collection and drainage of wastewater after cleaning, preventing contamination of the medical environment. The detachable connection between the cover plate 3 and the cleaning tank 2 allows for quick switching between intraoperative fluoroscopy and wound debridement functions.
