Description

Technical Field

[0001] This invention relates to the field of dressing change devices, and more particularly to a surgical dressing change device for the liver, gallbladder, pancreas, and spleen. Background Technology

[0002] In hepatobiliary and pancreatic surgery, postoperative wound care is crucial for ensuring a smooth recovery. Dressing changes, a fundamental surgical procedure, aim to remove wound secretions and residual medication, prevent infection, and promote tissue healing. This typically involves removing the old dressing, cleaning the wound, applying new medication, and re-bandaging. Because these surgeries are often performed on the abdomen, with the wound located in the mid-thigh, it is essential to ensure the wound is clean, dry, and tension-free during dressing changes. Currently, specialized dressing change beds are commonly used in clinical practice. Patients lie supine on a bed covered with a disposable blue sheet, and medical staff complete the entire dressing change process.

[0003] However, existing dressing change methods have some shortcomings: First, the liquid medications used during dressing changes tend to flow along the edge of the patient's abdomen, contaminating the bed sheet below. To prevent cross-infection, the entire bed sheet must be replaced after each dressing change, which is cumbersome and time-consuming, affecting the efficiency of dressing changes. Second, after wound treatment, gauze needs to be wrapped around the abdominal wound area to fix the dressing and isolate it from external interference. However, since patients are lying flat and have difficulty cooperating on their own, multiple medical staff usually need to help them sit up so that doctors can bandage around the waist and abdomen. This not only increases the manpower burden but may also cause discomfort to the patient or pull on the wound due to changes in body position. Therefore, it is necessary to design a convenient and efficient dressing change device for hepatobiliary, pancreatic and splenic surgery to address the shortcomings of existing technologies. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a dressing change device for hepatobiliary, pancreatic and splenic surgery, thereby assisting clinical hepatobiliary, pancreatic and splenic surgery in dressing changes and improving the convenience and efficiency of dressing changes.

[0005] Technical Solution: A surgical dressing change device for hepatobiliary and pancreatic surgery includes a dressing bed and a mattress. The dressing bed serves as the mounting carrier for the dressing change device, and a mattress for the patient to lie flat is laid on the bed board. It also includes guide frames symmetrically fixed on both sides of the dressing bed, with a sliding plate slidably connected between the two guide frames. Guide grooves for guiding the sliding plates are provided on the guide frames. A linear motor is fixedly installed at the bottom of the bed board, and the mover of the linear motor is connected to the sliding plate. An assembly box is fixedly installed on one side of the sliding plate. A first support shaft and a second support shaft are rotatably mounted vertically inside the assembly box. The first and second support shafts are respectively used to load wound medical gauze. The assembly box contains a gauze pad and a nursing pad. One side of the assembly box has a loading opening, and a rotatable door is mounted at the loading opening. A servo motor for driving a second support shaft is mounted on the assembly box. A guide frame with upper and lower openings is fixedly mounted on the other side of the sliding plate. Fixed rollers and sliding rollers are respectively mounted on opposite sides of the upper part of the guide frame, and both are driven by independent motors. An opening flush with the mattress is provided on the side wall of the assembly box facing the guide frame. The medical gauze and nursing pad loaded inside the assembly box pass through this opening. A guide component for guiding the sliding rollers is provided at the top of the guide frame, and a drive component for adjusting the position of the sliding rollers is provided on the outer wall of the guide frame.

[0006] In one embodiment, the guide is composed of a guide rail and a sliding frame. The guide rails are symmetrically fixed on both sides of the upper outer wall of the guide frame, and a sliding frame is slidably connected to the guide rails. The sliding roller is fixedly installed on the sliding frame.

[0007] In one embodiment, the driving component includes an electric push rod and a driving block. The electric push rod is fixedly installed on one side of the outer wall of the guide frame, and the driving block is fixedly connected to the piston rod of the electric push rod. The driving block is connected to the sliding frame. The electric push rod drives the sliding frame to slide along the guide rail through the driving block, so that the distance between the sliding roller and the fixed roller can be quickly adjusted, making it convenient for medical staff to insert the nursing pad between the fixed roller and the sliding roller.

[0008] In one embodiment, an mounting plate is fixedly connected to the outer wall of the assembly box facing the guide frame. Three support rods are provided on the mounting plate, and the three support rods are distributed in a triangular shape on the mounting plate. The upper support rod is used to support the medical gauze, and the other two support rods are used to guide and limit the medical gauze. The supported medical gauze is easy for medical staff to use.

[0009] In one embodiment, a cutting frame is fixedly installed on the inner wall of the guide frame near the sliding roller. The cutting frame has a sharp cutting edge on the side opposite to the inner wall of the guide frame. A mounting base is fixedly installed on the inner wall of the guide frame near the sliding roller. A cutter is slidably installed on the mounting base, with the cutting edge of the cutter facing the cutting edge of the cutting frame. A mounting shaft is fixedly installed inside the guide frame, and a drive plate is rotatably connected to the mounting shaft. A connecting rod is fixedly connected to the sliding frame. The drive plate is used to connect the cutter and the connecting rod. Sliding grooves are symmetrically opened at both ends of the drive plate, and the connecting rod and the cutter are distributed in the corresponding sliding grooves of the drive plate.

[0010] In one embodiment, the guide frame has symmetrical rails on both sides of the outer wall at the bottom opening, and a waste bin is slidably installed at the bottom of the guide frame via the rails. The waste bin is used to collect the cut contaminated care pads inside the guide frame. Guide frames adapted to the rails are fixedly installed on both sides of the top of the waste bin.

[0011] In one embodiment, a handle is installed on one side of the outer wall of the waste bin, which facilitates attaching or removing the waste bin from the bottom of the guide frame.

[0012] In one embodiment, a positioning needle is provided on the top of the sliding frame. The positioning needle is used to fix the initial segment of medical gauze and nursing pad that is brought out, to prevent wrinkles from forming when the medical gauze and nursing pad are stacked horizontally, and to ensure that they are flat and usable.

[0013] The beneficial effects are: 1. The present invention uses a linear motor to drive a sliding plate to move the assembly box and guide frame as a whole, which can quickly adjust the position of the medical gauze and nursing pad. The medical gauze and nursing pad are integrated in the same assembly box, and can be exported and layered at the same time. After the dressing is changed, the gauze can be pulled out directly to wrap the wound without the patient having to get up and cooperate, which simplifies the dressing and bandaging process.

[0014] 2. This invention uses a servo motor to drive the second support shaft to unwind the nursing pad, and in conjunction with a fixed roller and a sliding roller driven by an independent motor, it achieves stable delivery and clamping of the nursing pad, ensuring that it is laid flat and without wrinkles.

[0015] 3. This invention utilizes a sliding frame linked with a cutter and a cutting frame, which can automatically cut the contaminated section of the nursing pad after it enters the guide frame. At the same time, a detachable waste bin is provided at the bottom of the guide frame, which is installed by sliding along a rail, making it easy to collect the contaminated nursing pad after cutting, in accordance with medical waste management regulations.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] A surgical dressing change device for the liver, gallbladder, pancreas, and spleen; please refer to [link / reference]. Figures 1-5 As shown, the device includes a dressing bed 1 and a mattress 2. The dressing bed 1 serves as the mounting carrier for the dressing device, and a mattress 2 for the patient to lie on is laid on the bed board of the dressing bed 1. It also includes guide frames 3 symmetrically fixed on both sides of the dressing bed 1, with a sliding plate 4 slidably connected between the two guide frames 3. Guide grooves for guiding the sliding plate 4 are provided on the guide frames 3. A linear motor 5 is fixedly installed at the bottom of the bed board of the dressing bed 1, and the mover of the linear motor 5 is connected to the sliding plate 4. An assembly box 6 is fixedly installed on one side of the sliding plate 4. Inside the assembly box 6, a first support shaft 61 and a second support shaft 62 are respectively rotatably mounted vertically. The first support shaft 61 and the second support shaft 62 are used to load rolled medical gauze 100 and nursing pad 200, respectively. The assembly box 6 has a loading opening on one side, and an opening and closing door 63 is rotatably installed at the loading opening. A servo motor 7 for driving the second support shaft 62 is installed on the assembly box 6. A guide frame 8 with upper and lower openings is fixedly installed on the other side of the sliding plate 4. Fixed rollers 9 and sliding rollers 91 are respectively installed on the upper two sides of the guide frame 8. Both the fixed rollers 9 and sliding rollers 91 are driven by independent motors. An opening flush with the mattress 2 is opened on the side wall of the assembly box 6 facing the guide frame 8. The medical gauze 100 and nursing pad 200 loaded in the assembly box 6 pass through the opening. A guide member 10 for guiding the sliding roller 91 is provided on the top of the guide frame 8. A drive member 11 for driving the sliding roller 91 to adjust its position is provided on the outer wall of the guide frame 8.

[0028] Please see Figure 3 and Figure 5 As shown, the guide component 10 is composed of a guide rail 101 and a sliding frame 102. The guide rail 101 is symmetrically fixed on both sides of the upper outer wall of the guide frame 8. The sliding frame 102 is slidably connected to the guide rail 101, and the sliding roller 91 is fixedly installed on the sliding frame 102.

[0029] Please see Figure 3 and Figure 5 As shown, the driving component 11 includes an electric push rod 111 and a driving block 112. The electric push rod 111 is fixedly installed on one side of the outer wall of the guide frame 8. The driving block 112 is fixedly connected to the piston rod of the electric push rod 111. The driving block 112 is connected to the sliding frame 102. The electric push rod 111 drives the sliding frame 102 to slide along the guide rail 101 through the driving block 112, so that the distance between the sliding roller 91 and the fixed roller 9 can be quickly adjusted, making it convenient for medical staff to insert the nursing pad 200 between the fixed roller 9 and the sliding roller 91.

[0030] Please see Figure 3 and Figure 4As shown, an installation plate 12 is fixedly connected to the outer wall of the assembly box 6 facing the guide frame 8. Three support rods 121 are provided on the installation plate 12. The three support rods 121 are distributed in a triangular shape on the installation plate 12. The upper support rod 121 is used to support the medical gauze 100, and the other two support rods 121 are used to guide and limit the medical gauze 100. The supported medical gauze 100 is convenient for medical staff to take.

[0031] At the start of the operation, medical staff open the hinged door 63 of the assembly box 6 and load the rolled medical gauze 100 and nursing pad 200 onto the first support shaft 61 and the second support shaft 62 arranged vertically inside the box, respectively. Then, from the opening in the assembly box 6 towards the side wall of the guide frame 8, the medical gauze 100 and nursing pad 200 are led out of the guide frame 8. The pulled-out medical gauze 100 first passes through the three support rods 121 on the outer mounting plate 12 of the assembly box 6. The upper one supports it for easy access, while the lower two guide and limit it, ensuring that the medical gauze 100 and nursing pad 200 are flat and layered on the mattress 2 without wrinkles. At this time, the piston rod of the electric push rod 111 extends and pushes the drive block 112. The drive block 112 drives the sliding frame 102 to move along the guide rail 101, so that the sliding roller 91 in the guide frame 8 moves away from the fixed roller 9, leaving sufficient gap for the nursing pad 200. Personnel insert the front end of the nursing pad 200 into the gap, and then the electric push rod 111 reverses to reset the sliding roller 91. At this time, the sliding roller 91, driven by an independent motor, and the fixed roller 9 roll together to hold the nursing pad 200. Then, according to the actual dressing change site of the patient, the medical staff starts the linear motor 5 installed at the bottom of the bed board. The mover of the linear motor 5 drives the sliding plate 4. The two sides of the sliding plate 4 are precisely guided by the guide grooves on the guide frame 3, thereby driving the assembly box 6 fixed on one side and the guide frame 8 on the other side to slide synchronously, so that the medical gauze 100 laid on the mattress 2 and the nursing pad 200 can be accurately aligned with the patient's wound. After the preparation is complete, the patient lies flat on the mattress 2. When changing the dressing, the nursing pad 200 isolates the contamination. After the dressing change is completed, the medical staff can directly pull the medical gauze 100 supported by the support rod 121 for covering and bandaging, improving the convenience and efficiency of the medical staff in changing the dressing.

[0032] Please see Figure 6As shown, a cutting frame 13 is fixedly installed on the inner wall of the guide frame 8 near the sliding roller 91. The side of the cutting frame 13 facing away from the inner wall of the guide frame 8 has a sharp cutting edge. A mounting base 131 is fixedly installed on the inner wall of the guide frame 8 near the sliding roller 91. A cutter 132 is slidably installed on the mounting base 131. The cutting edge of the cutter 132 faces the cutting edge of the cutting frame 13. A mounting shaft 133 is fixedly installed inside the guide frame 8. A drive plate 134 is rotatably connected to the mounting shaft 133. A connecting rod 136 is fixedly connected to the sliding frame 102. The drive plate 134 is used to connect the cutter 132 and the connecting rod 136. Slide grooves 135 are symmetrically opened at both ends of the drive plate 134. The connecting rod 136 and the cutter 132 are distributed in the corresponding slide grooves 135 of the drive plate 134.

[0033] When it is necessary to cut the contaminated nursing pad 200, the sliding frame 102 and the sliding roller 91 are driven away from the fixed roller 9 by the electric push rod 111. At this time, the connecting rod 136 on the sliding frame 102 will push the drive plate 134, so that the drive plate 134 rotates around the mounting shaft 133 as the rotation center. The rotating drive plate 134 will push the cutter 132 to move towards the cutting frame 13, so that the cutter 132 engages with the cutting edge of the cutting frame 13 to cut the nursing pad 200 that has been introduced into the guide frame 8, so that the cut nursing pad 200 can be collected and processed in a centralized manner later.

[0034] Please see Figure 7 and Figure 8 As shown, the guide frame 8 has symmetrically arranged rails 81 on both sides of the outer wall at the bottom opening. The waste bin 14 is slidably installed at the bottom of the guide frame 8 via the rails 81. The waste bin 14 is used to collect the cut contaminated care pads 200 inside the guide frame 8. The top two sides of the waste bin 14 are fixedly provided with guide frames 141 adapted to the rails 81.

[0035] Please see Figure 8 As shown, a handle 142 is installed on one side of the outer wall of the waste bin 14, which facilitates the installation or removal of the waste bin 14 from the bottom of the guide frame 8.

[0036] After a single dressing change is completed, the servo motor 7 drives the second spindle 62 to unwind the roll. Simultaneously, the fixed roller 9 and sliding roller 91, driven by the motor, rotate together inside the guide frame 8, continuously dragging the contaminated section of the nursing pad 200 from the mattress 2 through the opening. The contaminated nursing pad 200 is continuously guided into the guide frame 8 with its upper and lower openings. When it is necessary to separate the contaminated section from the subsequent cleaning roll, the drive unit 11 actuates again, causing the sliding roller 91 to move away from the fixed roller 9. This movement releases the clamping of the nursing pad 200 and, through the connecting rod 136, pushes the connected drive plate 134 around the guide frame. The mounting shaft 133 inside the guide frame 8 rotates, and the rotating drive plate 134 converts the linear motion of the sliding frame 102 into the precise advancement of the cutter 132 toward the cutting edge of the cutting frame 13, completing the cutting of the nursing pad 200 inside the guide frame 8. The cut-off contaminated nursing pad 200 segments fall into the waste bin 14 prepared in advance at the bottom of the guide frame 8 under the action of gravity. The waste bin 14 is slidably installed at the bottom of the guide frame 8 via the rail 81. When the waste bin 14 is full of waste nursing pads 200, medical staff can remove the waste bin 14 through the handle 142 and safely dispose of the waste nursing pads 200.

[0037] Please see Figure 7 and Figure 9 As shown, a positioning needle 15 is provided on the top of the sliding frame 102. The positioning needle 15 is used to fix the initial segment of medical gauze 100 and nursing pad 200, preventing wrinkles from forming when the medical gauze 100 and nursing pad 200 are stacked horizontally, and ensuring that they are flat and usable.

[0038] To further improve the flatness of the stacked medical gauze 100 and nursing pad 200, during the initial laying of the medical gauze 100 and nursing pad 200, medical staff actively puncture and fix the initial section of the medical gauze 100 and nursing pad 200 to the positioning needle 15. The positioning needle 15 can effectively restrict the free ends of the medical gauze 100 and nursing pad 200, preventing them from shrinking, shifting, or wrinkling during subsequent laying, movement of the sliding board 4 as a whole, or during the patient's lying down. This ensures that the materials always fit flat against the surface of the mattress 2. When the dressing change is completed and the materials need to be replaced or recycled, medical staff only need to remove the punctured and fixed initial section from the positioning needle 15 to carry out subsequent operations.
