Description

Technical Field

[0001] This invention relates to a multifunctional surgical tray with a robotic arm support, belonging to the field of operating room tray technology. Background Technology

[0002] Maintaining a sterile environment is crucial for ensuring patient safety and surgical quality during surgery. Therefore, surgical instruments, consumables, and medications must undergo rigorous sterilization before surgery begins and be placed in a sterile tray for use. Typically, the sterile tray is placed on a surgical trolley, and the surgical nurse provides the necessary instruments during the procedure as needed by the surgeon. However, current trolley layouts often result in a distance between the tray and the surgical area, which can easily lead to interruptions in concentration and delayed responses during retrieval. In high-intensity, high-risk surgical scenarios, such delays can affect the safety and efficiency of the surgery.

[0003] Furthermore, during the draping process before surgery, medical staff need to remove the drape from its packaging, unfold it, and cover the patient's body surface after skin disinfection. This process must be carried out under strict aseptic conditions, but draping requires multiple steps and the cooperation of several people, repeatedly handling the drape and pulling its four corners to move it to the required position to complete the draping. Even slight carelessness could lead to contact with an unsterilized environment or the area surrounding the patient, thus compromising the aseptic state.

[0004] To address the above issues, a surgical tray system was designed to improve operational efficiency and reduce the risk of human contamination. Based on a traditional sterile tray, a controllable robotic arm and an automatic drape-laying mechanism are integrated, allowing the tray structure to suspend above the operating table and freely enter and exit the surgical area as needed. The tray is multifunctional, enabling automated and precise drape laying before surgery and timely and stable instrument delivery during surgery, reducing the number of times medical staff repeatedly handle sterile items. It not only improves the surgical procedure and enhances operational convenience but also significantly reduces the possibility of sterile contamination, effectively improving surgical safety. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multifunctional surgical tray with a robotic arm support, which solves the problems of low operating efficiency and risk of contamination caused by placing surgical drapes in the tray for use in the operating room.

[0006] The technical problem to be solved by this invention is achieved by the following technical solution:

[0007] A multifunctional surgical tray with a robotic arm support includes:

[0008] A multi-axis support includes a connecting shaft and a robotic arm that drives the connecting shaft to perform translational motion along the X, Y, and Z axes and to perform rotational motion about the Z-axis of the connecting shaft as the central axis. The robotic arm is mounted on one side of the operating table.

[0009] The tray assembly includes a tray frame mounted on the connecting shaft and a tray body mounted on top of the tray frame via a quick-installation mechanism. The tray frame also has a diaper-laying assembly for downward-releasing diapers.

[0010] As a preferred example, the robotic arm includes:

[0011] The base is fixed to one side of the operating table by a support column;

[0012] The first rotating arm is mounted on the base via a first rotating joint;

[0013] The second rotating arm is mounted at the end of the first rotating arm via a second rotating joint;

[0014] A lifting cylinder is mounted at the end of the second rotating arm via a third rotating joint, and the piston rod of the lifting cylinder serves as the connecting shaft.

[0015] As a preferred example, the quick installation mechanism uses multiple magnetic blocks fixed to the four sides of the tray frame. The tray body is made of medical stainless steel and fits perfectly into the frame of the tray frame, where it is quickly attracted and fixed by the magnetic blocks.

[0016] As a preferred example, the burlap liner installation assembly includes a burlap liner roll, a release assembly for releasing the burlap liner roll, and a recycling assembly for recycling the burlap liner roll, which are respectively fixed on opposite sides of the tray frame. The burlap liner roll secures multiple burlap liner rolls via a quick-release structure.

[0017] As a preferred example, the quick-release structure includes magnetic snaps fixed at the four corners of the drape and hollow magnetic pieces fixed at corresponding positions on the drape roll. The drape is fixed to the lower surface of the drape roll by the magnetic snaps and the hollow magnetic pieces.

[0018] As a preferred example, the drape has magnetic snaps on both the top and bottom surfaces, and the magnetic snaps on the bottom surface of the drape are attracted and fixed to a magnetic adhesive sheet.

[0019] As a preferred example, the release assembly includes a release cylinder and a first rotating rod coaxially disposed within the release cylinder, on which a kerchief roll is wound up. The recycling assembly includes a recycling cylinder and a second rotating rod coaxially mounted within the recycling cylinder and driven by a winding motor. The end of the kerchief roll is pulled from the release cylinder into the recycling cylinder and fixed to the second rotating rod. The end of the first rotating rod of the release cylinder is provided with an adjustable damping mechanism.

[0020] As a preferred example, the winding motor is a geared worm motor, the towel roll is provided with a position marking hole, and a reflective photoelectric sensor is provided above the position marking hole for controlling the winding motor to stop by sensing the position of the position marking hole.

[0021] As a preferred embodiment, the inner side of the tray frame is equipped with a release device for automatically releasing the drape. The drape roll has multiple positioning holes on both sides outside the drape fixing area. The bottom of both sides of the tray frame is provided with limiting plates for supporting the edges of the drape roll. The limiting plates are provided with fixing holes opposite to the positioning holes. The release device includes an electromagnetic telescopic rod for penetrating the positioning holes and fixing holes, and an electric push rod located above the hollow hole of the hollow magnetic sheet for releasing the drape.

[0022] As a preferred example, the bottom of both the electromagnetic telescopic rod and the electric jack rod adopts a hemispherical end.

[0023] The beneficial effects of this invention are:

[0024] 1. By mounting the tray on the robotic arm, it can be moved to any position on the operating table as needed during surgery, enabling more efficient retrieval and placement of items;

[0025] 2. Furthermore, the drape can be removed using the drape-laying component under the tray, and the sterile drape can be quickly moved to the patient's surgical area using the robotic arm of the original tray. During this movement, the drape will not come into contact with the operator, making it cleaner and safer.

[0026] 3. The drape roll has multiple independent drapes secured by a quick-release mechanism, which allows the drapes to be easily separated from the roll once they reach the designated position;

[0027] 4. The release device automatically separates the four corners of the drape from the drape roll, further reducing manual intervention and improving the efficiency and cleanliness of drape installation. Attached Figure Description

[0045] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0046] This multifunctional surgical tray with a robotic arm and three supports is used in the operating room. The sterile tray in the operating room needs to hold basic surgical instruments, sterile consumables, and disinfection supplies, including a 6-panel drape. All items must be arranged in an orderly manner according to aseptic operating procedures to keep the sterile area uncontaminated. The sterile tray is generally placed on a medical trolley for later use.

[0047] Before using the perforated drape 6, the skin in the surgical area needs to be disinfected and dried. Then, the assistant or scrub nurse will pass the sterile perforated drape. The surgeon will hold the edge of the perforated drape 6, align it with the center of the surgical incision, and unfold it to precisely cover the surgical area. The perforated drape 6 will then be secured around the perimeter to ensure that the non-surgical area is completely covered and only the surgical field is exposed. During the draping process, hands and sterile items must not touch non-sterile areas. If the perforated drape 6 shifts or becomes contaminated, it must be replaced immediately. Once laid down, it must not be moved or adjusted arbitrarily to maintain a sterile state throughout the process.

[0048] In actual surgical draping procedures, if the initial placement of the perforated drape 6 is inaccurate, manual fine-tuning is required. On one hand, pulling or moving the perforated drape 6 can easily disrupt the surrounding sterile drapes, damaging the sterile barrier. On the other hand, during adjustments, the surgeon's hands need to move repeatedly above the surgical area, and a slight miscalculation could cross the sterile boundary, causing contamination of the sterile area. Furthermore, repeated adjustments prolong draping time and reduce surgical efficiency. Therefore, the accuracy of the perforated drape 6 placement is crucial, and currently, it is difficult for surgeons to achieve precise placement on the first attempt, requiring multiple manual fine-tunings. To improve the initial placement accuracy of the perforated drape 6, its placement is integrated into the robotic arm 3 of the moving tray. This allows for precise, suspended alignment before placement, achieving high-precision perforated drape 6 placement and reducing the risk of contamination caused by manual adjustments.

[0049] Furthermore, if the surgical drape 6 becomes contaminated during surgery, it needs to be replaced promptly. This can be achieved quickly using a multifunctional surgical tray equipped with a robotic arm 3 and a drape-laying assembly 5. This automated drape-laying not only improves surgical efficiency but also prevents contamination of the drape 6, enhancing safety.

[0050] like Figure 1 , Figure 2As shown, this multifunctional surgical tray with a robotic arm 3 mainly includes a multi-axis support 1 for precise movement and a tray assembly 2 mounted on the multi-axis support 1. The multi-axis support 1 includes a connecting shaft 101 and a robotic arm 3 that drives the connecting shaft 101 to perform translational movements along the X, Y, and Z axes and to perform rotational movements about the Z-axis of the connecting shaft 101 as the central axis. The robotic arm 3 is mounted on one side of the operating table 4. The tray assembly 2 includes a tray frame 201 mounted on the connecting shaft 101 and a tray body 202 mounted on top of the tray frame 201 via a quick-installation mechanism. A drape laying assembly 5 for downwardly releasing the drape 6 is also mounted on the tray frame 201.

[0051] In some embodiments, to minimize the size of the robotic arm 3 and avoid affecting the surgical field of vision and standing space, a simple robotic arm 3 structure is adopted. The robotic arm 3 includes a base 302 fixed to one side of the operating table 4 via a support column 301, a first rotating arm 304 mounted on the base 302 via a first rotating joint 303, a second rotating arm 306 mounted at the end of the first rotating arm 304 via a second rotating joint 305, and a lifting cylinder 308 mounted at the end of the second rotating arm 306 via a third rotating joint 307. The piston rod of the lifting cylinder 308 serves as a connecting shaft 101. The first rotating joint 303, second rotating joint 305, and third rotating joint 307 are all equipped with geared servo motors, and the lifting cylinder 308 is an electric lifting rod. The robotic arm 3 can drive the connecting shaft 101 to perform translational movements in the X, Y, and Z axes, and can also rotate around the Z-axis. This allows the robotic arm 3 to suspend the tray and drape-laying assembly 5 above the desired position for item retrieval and drape laying.

[0052] like Figure 3 As shown, in some embodiments, in order to stably fix the tray after the drape 6 is laid out and to facilitate the replacement of the new tray (the robotic arm 3 needs to move the tray frame 201 away from the operating table 4 before replacing the tray), a quick-installation mechanism is provided on the tray frame 201. The quick-installation mechanism uses multiple magnetic blocks 203 fixed on the frame of the tray frame 201. The tray body 202 is made of medical stainless steel and fits exactly into the frame of the tray frame 201 and is fixed by magnetic blocks 203.

[0053] like Figure 4As shown, in some embodiments, the burlap liner laying assembly 5 includes a burlap liner roll 204, and a release assembly for releasing the burlap liner roll 204 and a retrieval assembly for retrieving the burlap liner roll 204, respectively fixed to opposite sides of the tray frame 201. The burlap liner roll 204 secures multiple burlap liner sheets 6 via a quick-release structure. The release assembly includes a release cylinder 205 with a release opening, and a first rotating rod 206 coaxially disposed within the release cylinder 205, on which the burlap liner roll 204 is wound. The retrieval assembly includes a retrieval cylinder 207 with a retrieval opening, and a second rotating rod 209 coaxially mounted within the retrieval cylinder 207 and driven by a winding motor 208. The end of the burlap liner roll 204 is pulled from the release cylinder 205 into the retrieval cylinder 207 and fixed to the second rotating rod 209.

[0054] The drape roll 204 is packaged in disposable aseptic packaging. Before use, it is opened and installed in the release cylinder 205. The drape roll 204 is then pulled out from the release opening and inserted into the recovery opening of the recovery cylinder 207, where it is fixed to the internal second rotating rod 209. The second rotating rod 209 of the recovery cylinder 207 is quickly connected to the reduction worm gear motor, facilitating the removal and unloading of the used drape roll 204. Similar to the structure of a film camera, this design enables the release and recovery of the drape roll 204.

[0055] like Figure 5 As shown, in order to make the release of the drape roll 204 more stable, an adjustable damping mechanism is provided at the end of the first rotating rod 206 of the release cylinder 205. The adjustable damping mechanism adopts a hand-tightening bolt 210 with a rubber head at the end. The hand-tightening bolt 210 is screwed into the tray frame 201, and the rubber head abuts against the first rotating rod 206. A certain pulling force is required to release the drape roll 204, thus playing a damping role.

[0056] like Figures 6-8 As shown, in some embodiments, the quick-release structure includes magnetic snaps 601 fixed at the four corners of the draped towel 6, and hollow magnetic pieces 211 fixed at corresponding positions on the draped towel roll 204. The draped towel 6 is fixed to the lower surface of the draped towel roll 204 by the magnetic snaps 601 and the hollow magnetic pieces 211. Figure 6 The dotted line represents the drape 6 below the drape roll 204. The drape roll 204 is made of a semi-transparent plastic sheet to allow observation of whether the opening of the drape 6 is directly above the surgical area. Once the drape 6 is fully released, with the central opening facing the surgical area, manually push the pusher downwards through the hollow hole of the hollow magnetic clasp 211. This separates the magnetic clasp 601 from the hollow magnetic clasp 211, allowing the edges of the drape 6 to fall onto the patient, completing the release of the drape 6. The tray frame 201 should be suspended 3-5 cm above the patient's surgical area for more accurate drape release.

[0057] like Figure 9As shown, in some embodiments, the drape 6 has magnetic snaps 601 on both the top and bottom surfaces, and the magnetic snaps 601 on the bottom surface of the drape 6 are attracted and fixed to the magnetic adhesive sheet 602.

[0058] During surgery, the patient's position may need to change. To ensure the drape 6 adheres tightly to the patient and does not easily shift position, thus avoiding interference with the surgical procedure, magnetic adhesive sheets 602 are attached to the magnetic snaps 601 on the lower surface of the drape 6. These adhesive sheets 602 are then used to attach the drape to the patient's skin. If the drape 6 needs to be replaced, the magnetic snaps 601 at the four corners of the drape 6 can be detached from the adhesive sheets 602. The adhesive sheets 602 mark the original positions of the drape 6 for easy replacement with a new one. The adhesive sheets 602 are disposable and sterile, using medical pressure-sensitive adhesive. Before use, they are covered with release paper. After the drape 6 is laid out, the release paper is peeled off, and the adhesive sheets 602 are placed between the magnetic snaps 601 at the four corners of the drape 6 and the patient's skin. Gently press the four corners of the drape 6 to ensure a tight fit.

[0059] like Figures 6-9 As shown, in some embodiments, a release device 7 for automatically releasing the drape 6 is installed inside the tray frame 201. The drape roll 204 has multiple positioning holes 212 (located at the four corner edges of the drape roll 204) on both sides outside the fixed area of ​​the drape 6. The bottom of both sides of the tray frame 201 is provided with limiting plates 213 for supporting the edges of the drape roll 204. The limiting plates 213 are provided with fixing holes 214 opposite to the positioning holes 212. The release device 7 includes an electromagnetic telescopic rod 701 for penetrating the positioning holes 212 and the fixing holes 214, and an electric push rod 702 located above the hollow hole of the hollow magnetic suction piece 211 for releasing the drape 6.

[0060] The electromagnetic telescopic rod 701 and the electric jacking rod 702 are fixed side-by-side to the inside of the tray frame 201 via the same mounting plate 218. The electromagnetic telescopic rod 701 is a commercially available product, employing a telescopic rod structure driven by an electromagnetic coil. In the non-energized state, the telescopic rod is lifted by a spring; when energized, the magnetic attraction generated by the electromagnetic coil overcomes the spring force, attracting the magnet in the middle of the telescopic rod downwards, penetrating the positioning hole 212 and the fixing hole 214. Since there is no significant obstruction force throughout the process, the electromagnetic telescopic rod 701 can complete the action well, eliminating the need for the electric jacking rod 702 with its greater telescopic force. However, to eject and separate the magnetic catch 601 from the hollow hole of the hollow magnetic catch plate 211, a commercially available electric jacking rod 702 with a greater lifting force is used. This rod uses a rotor to drive a screw, thereby ejecting the threaded sleeve. The screw-driven method converts the high-speed rotation of the rotor into a slow translational motion of the threaded sleeve, thus ejecting the magnetic catch 601.

[0061] To ensure the towel roll 204 can overcome damping and stably release and rewind the same distance (moving one towel roll spacing 6 each time) during each run, the winding motor 208 is a geared worm motor. The towel roll 204 has a position marking hole 215 (the limiting plate 213 below the position marking hole 215 has a perforated section to avoid affecting the position recognition of the reflective photoelectric sensor 216). Above the position marking hole 215 is a reflective photoelectric sensor 216 used to control the winding motor 208 to stop by sensing the position of the position marking hole 215. The position marking hole 215 and the positioning hole 212 are offset and not on the same running trajectory to prevent the reflective photoelectric sensor 216 from misidentifying the position. A cover plate 217 fixed to the tray frame 201 is provided above the release device 7. The cover plate 217 prevents the movement of the components below from being interfered with when the roll body 202 is fixed, and also serves to shield the reflective photoelectric sensor 216 from interference by ambient light.

[0062] The specific operating steps are as follows:

[0063] (1) Replacement of drape 6: Before laying drape 6, remove the disc 202 to expose the drape roll 204, so as to make it easier to observe whether the opening position of drape 6 matches the surgical area; each time the worm gear motor is started, the worm gear motor decelerates through the worm structure and outputs high torque to pull the drape roll 204 to rewind.

[0064] (2) Replacement of the burlap 6 is completed: When the reflective photoelectric sensor 216 detects the position marking hole 215 on the edge of the burlap roll 204, the deceleration worm motor stops rotating. At this time, the burlap 6 is located in the middle, and the positioning hole 212 and the fixing hole 214 overlap vertically and are both located directly below the electromagnetic telescopic rod 701. The hollow hole of the hollow magnetic suction piece 211 is located directly below the electric push rod 702.

[0065] (3) Release the drape 6 to the patient's surgical area: After the robotic arm 3 moves the drape 6 to the surgical area, it first controls the electromagnetic telescopic rod 701 to extend, pass through the positioning hole 212 and the fixing hole 214, and fix the four corners of the drape roll 204. First, fix it to keep the drape roll 204 taut, so as to prevent the drape roll 204 from loosening when pushing out the magnetic buckle 601, which would lead to the failure of pushing out; then control the electric push rod 702 to gradually extend, and separate the magnetic buckles 601 at the four corners of the drape 6 through the hollow hole of the hollow magnetic plate 211, so that the drape 6 falls down automatically. Since the drape 6 is close to the patient's skin, the position is relatively accurate after falling down, and generally no further adjustment is needed. The whole process does not require manual laying, which improves the laying efficiency and avoids contamination from non-sterilized areas.

[0066] To overcome minor positioning errors, in some embodiments, the bottom of the electromagnetic telescopic rod 701 and the electric jack 702 both adopt hemispherical ends. When the electromagnetic telescopic rod 701 and the electric jack 702 pass downward through the hole, the hemispherical ends can adjust the position of the towel roll 204 and the towel 6 to a certain extent, and finally complete the preset action without any jamming problem.
