Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a debridement machine for operating room nursing. Background Art

[0002] Debridement is a common surgical procedure in operating room nursing, primarily used to treat open wounds. Its purpose is to remove foreign matter, necrotic tissue, and bacteria from the wound, preventing infection and promoting wound healing. Debridement involves cleaning, excising necrotic tissue, achieving hemostasis, suturing, draining, and bandaging to ensure wound cleanliness and effective healing, preventing infection and minimizing complications.

[0003] In traditional operating rooms, when performing debridement on a patient's arm, it usually requires the cooperation of multiple people: one person supports and stabilizes the patient's arm, one person is responsible for debridement, and another person is responsible for lighting and cleaning the wound. This is time-consuming and labor-intensive, and it can easily cause the patient's arm to shake, resulting in incomplete debridement or aggravating the patient's injury.

[0004] After searching, the Chinese patent with the announcement number CN113663236A discloses a precise debridement machine, including a debridement machine body, an auxiliary clamping mechanism, a cleaning and disinfection mechanism, and a control host placed on the top of the debridement machine body. The upper end of the second hose is provided with a waste liquid recovery head, the middle is provided with a negative pressure pump, and the debridement machine body is provided with an auxiliary detection mechanism. The auxiliary detection mechanism performs near-infrared detection on the wound surface. The auxiliary detection mechanism can detect different positions and transmit the detection information to the control host. The control host then transmits it to the ultrasonic debridement head to perform precise debridement on the wound surface, so as to ensure that while thoroughly removing necrotic tissue, the damage is controlled to the minimum as much as possible, and the interstitial ecological tissue, skin appendages and their related stem cells are preserved to the greatest extent. This is of great significance for improving the quality of wound healing and reducing scar formation.

[0005] The existing technology has the following problems: 1) The existing device mainly relies on the operation of medical staff and the data transmission of auxiliary detection mechanisms. It lacks a mechanism for automatically fixing the patient's limbs and a structure for selectively exposing the debridement site; 2) The existing device cannot be stored and takes up a large amount of space, resulting in low efficiency and cleanliness of the operating room. Summary of the Invention

[0011] Further: the transmission module includes: a first rack fixedly arranged on the limb placement block; A gear is rotatably mounted on the support mounting frame, with two sides of the gear respectively meshing with the first rack and the second rack; The second rack is slidably arranged on the support mounting frame, and the upper end is rotatably connected to the rotating member.

[0012] Furthermore: the limb clamping plate is provided with an adjustment protection assembly, the adjustment protection assembly includes a plurality of first protection plates, a plurality of second protection plates and a self-locking module; The first protective plates and the second protective plates are distributed up and down and are slidably arranged on the limb clamping plate. Self-locking modules are arranged between the plurality of first protective plates and the plurality of second protective plates and the limb clamping plate.

[0013] Further: the self-locking module includes: An arc-shaped track groove is provided on the limb clamping plate; Multiple groups of locking members, each group of locking members has two members, and are relatively arranged on both sides of the arc-shaped track groove through a first torsion spring; The locking assembly is arranged at the end of the corresponding first protective plate or the second protective plate, and the locking assembly cooperates with the locking member to lock the position of the first protective plate or the second protective plate.

[0014] Furthermore: the locking assembly includes a pair of gap-connected locking members, the opposite surfaces of the two locking members have the same magnetic properties and are different from the magnetic properties of the locking member, and the separated surfaces of the two locking members have the same magnetic properties and are the same as the magnetic properties of the locking member.

[0015] Further: the pedal unlocking mechanism includes: A foot pedal, slidably arranged on the side wall of the control box; an adjustment assembly connected to the foot pedal; The hook-shaped limit block is slidably arranged on the control box and is rotationally connected to the adjustment component to limit the slide rod.

[0016] Further: the adjustment component includes: a second rotating rod connected to the foot pedal; A push rod, horizontally slidably arranged in the control box, and rotatably connected to the second rotating rod and the third rotating rod; The third rotating rod has one end rotatingly connected to the front end of the push rod and the other end rotatingly connected to the hook-shaped limit block.

[0017] Further: it also includes a storage box slidably arranged on a side of the control box away from the pedal unlocking mechanism; The push rod passes through the control box horizontally and abuts against the storage box.

[0018] The beneficial effects of the present invention are: 1.

Medical staff can slide and adjust the position of the first and second protective plates according to the debridement needs, and lock them with the self-locking module to selectively expose the debridement area of ​​the patient's limb. The selective debridement area exposure function enables medical staff to treat wounds more precisely and avoid unnecessary tissue damage.

[0019] 3. The support mechanism is connected to the control box through a second torsion spring and can be locked and unlocked by a foot-operated unlocking mechanism. When the medical staff steps on the foot pedal, the foot-operated unlocking mechanism releases the lock on the support mechanism, and the support mechanism automatically opens under the action of the second torsion spring, facilitating the installation of the limb clamping mechanism. At the same time, the foot-operated unlocking mechanism also controls the extension of the storage box, making it convenient for medical staff to access debridement instruments. The interaction between the support mechanism, the foot-operated unlocking mechanism and the storage box makes the operation of the machine easier and faster. Medical staff can complete the opening and closing of the support mechanism and the extension of the storage box through simple foot-operated movements. Through the special storage design, the debridement machine of the present application helps to improve the efficiency and cleanliness of the operating room and reduce the time and energy of medical staff in accessing and organizing debridement items.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0024] Example 1 See Figures 1 to 5 The present application discloses a debridement machine for operating room nursing, including a control box 1, a limb clamping mechanism 2, a support mechanism 3, a foot unlocking mechanism 4 and a storage box 5. The support mechanism 3 is arranged on the upper side of the control box 1, and the limb clamping mechanism 2 is detachably connected to the upper side of the support mechanism 3. The limb clamping mechanism 2 is used to automatically clamp and fix the patient's limbs and expose the part of the affected limb that needs debridement. A foot unlocking mechanism 4 is arranged below the same side of the control box 1 and the support mechanism 3. The foot unlocking mechanism 4 quickly opens and locks the support mechanism 3, and the foot unlocking mechanism 4 also controls the extension of the storage box 5.

[0025] Specifically, the control box 1 has a control screen 101 and an interface 102 located above the body. The control screen 101 displays the user interface, controls the various functions of the debridement machine, and provides real-time feedback on the machine's operating status. Interface 102 is used to connect external devices (such as a power supply or data transmission cable) to power the debridement machine or transmit data. A brake wheel 103 is located below the control box 1. This brake wheel 103 facilitates movement and secures the debridement machine during operation, preventing it from moving and ensuring safe and stable surgery.

[0026] It is worth noting that the limb clamping mechanism 2 includes a support mounting frame 201, a limb placement block 202 and a limb clamping plate 203. The support mounting frame 201 is detachably connected to the support mechanism 3. The support mounting frame 201 is connected to the limb placement block 202 through an adjusting piece. The limb clamping plate 203 is suspended above the limb placement block 202. Specifically, the limb clamping plate 203 is connected to the limb placement block 202 through two sets of control components. The limb placement block 202 cooperates with the limb clamping plate 203 to automatically fix the affected limb. The patient triggers the adjusting piece and the control component through the limb placement block 202, so that the limb clamping plate 203 automatically approaches the limb placement block 202, thereby realizing automatic clamping of the patient's limb, which is suitable for patients of different body shapes.

[0027] In particular, the control component includes a transmission module, a rotating member 204, a slider 205 and an extrusion rod 206. The transmission module is installed on the support mounting frame 201. One end of the transmission module is fixedly connected to one side of the limb placement block 202, and the other end is rotatably connected to one end of the rotating member 204. The other end of the rotating member 204 is rotatably connected to one end of the slider 205. The other end of the slider 205 is rotatably connected to one end of the extrusion rod 206. The other end of the extrusion rod 206 is rotatably connected to the limb clamping plate 203. The slider 205 slides on the top of the support mounting frame 201.

[0028] Among them, the transmission module includes a first rack 207, a gear 208 and a second rack 209. One end of the first rack 207 is fixedly connected to the limb placement block 202, and the other end is engaged with the gear 208. The gear 208 is rotatably set on the support mounting frame 201. The gear 208 is engaged with the second rack 209. The first rack 207 and the second rack 209 are on both sides of the gear 208. The second rack 209 is slidably connected to the support mounting frame 201, and the upper end of the second rack 209 is rotatably connected to the rotating member 204.

[0029] It should be noted that in the present application, the adjusting member selects the first spring 210. The function of the first spring 210 is to keep the limb placement block 202 in a higher position when the limb is not placed on it. When the limb is placed on the limb placement block 202, the weight of the limb causes the limb placement block 202 to compress the first spring 210 downward, thereby triggering the transmission module (first rack 207, gear 208, second rack 209) to drive the limb clamping plate 203 to automatically approach and clamp the limb, thereby realizing automatic fixation.

[0030] In this embodiment, when the limb clamping mechanism 2 is in use, the limb is placed in the limb placement block 202. Under the action of the limb's gravity, the limb placement block 202 compresses the first spring 210 downward, and the limb placement block 202 moves downward, triggering the transmission module, that is, the first rack 207 moves downward together with the limb placement block 202, and the first rack 207 drives the gear 208 to rotate, and the rotation of the gear 208 drives the second rack 209 to slide upward, and the upward sliding of the second rack 209 drives the rotating part 204 to rotate inward, thereby pushing the slider 205 to slide inward on the top of the support mounting frame 201, and then the extrusion rod 206 pushes the limb clamping plate 203 close to the limb.

[0031] Furthermore, in order to selectively expose the debridement area of ​​the patient's limb, an adjustment protection component is provided on the limb clamping plate 203, and the adjustment protection component includes a first protection plate 211, a second protection plate 212 and a self-locking module. The limb clamping plate 203 is provided with multiple sliding and vertically distributed first protection plates 211 and second protection plates 212, and self-locking modules are provided between the multiple first protection plates 211 and the multiple second protection plates 212 and the limb clamping plate 203.

[0032] Specifically, the self-locking module includes an arcuate track groove, multiple groups of locking parts 213 and a locking assembly. The arcuate track groove is opened on the front and rear sides of the limb clamping plate 203, and is used to set multiple groups of locking parts 213. Each group of locking parts 213 has two and is relatively arranged on both sides of the arcuate track groove through a first torsion spring 215; the locking assembly is arranged at the end of the corresponding first protective plate 211 or the second protective plate 212, and the locking assembly cooperates with the locking part 213 to lock the position of the first protective plate 211 or the second protective plate 212, that is, the sliding of the first protective plate 211 and the second protective plate 212 drives the locking assembly to slide together, and then the position of the locking assembly is locked by the locking part 213, thereby locking the position of the first protective plate 211 or the second protective plate 212.

[0033] Furthermore, the locking assembly includes a pair of gap-connected locking members 214 , wherein the opposing surfaces of the two locking members 214 have the same magnetic properties and are magnetically different from the locking member 213 , and the separated surfaces of the two locking members 214 have the same magnetic properties and are magnetically the same as the locking member 213 .

[0034] It should be added that when the protective assembly is adjusted for use, the first protective plate 211 and the second protective plate 212 are slidably adjusted according to the debridement site. When sliding, the positioning components respectively arranged at one end of the first protective plate 211 and the second protective plate 212 slide together. Since the two positioning members 214 are magnetically the same as the locking member 213 when the two positioning members 214 are separated from each other, the two positioning members 214 are close to the pair of locking members 213 when sliding. The two positioning members 214 are magnetically repelled from each other by the locking member 213 when the two positioning members 214 are separated from each other. 213 drives the first torsion spring 215 to rotate, providing a channel for the two locking members 214 to slide through. When the two locking members 214 just slide to the middle of the locking member 213, the locking member 213 is in the gap between the two locking members 214. Since the magnetic properties of the opposite surfaces of the two locking members 214 are different from those of the locking member 213, the locking member 213 is attracted, so that the locking member 213 drives the first torsion spring 215 to reset, thereby limiting the locking assembly and positioning the first protective plate 211 and the second protective plate 212.

[0035] Furthermore, to facilitate rapid installation and removal of the limb clamping mechanism 2 and the support mechanism 3, and to enhance the flexibility and convenience of the device, a clamp is provided at the bottom of the support mounting frame 201, which is detachably connected to the support mechanism 3. This design allows medical personnel to quickly install or remove the limb clamping mechanism 2 when needed, to accommodate different surgical needs or to clean and maintain the device.

[0036] Example 2 See Figures 6 to 11On the basis of the first embodiment, the second embodiment provides a specific structure of a support mechanism 3, a foot unlocking mechanism 4 and a storage box 5. The support mechanism 3 is arranged on the upper side of the control box 1, and the foot unlocking mechanism 4 is arranged below the control box 1 and the support mechanism 3 on the same side. The foot unlocking mechanism 4 locks the support mechanism 3. When the foot unlocking mechanism 4 unlocks the support mechanism 3, the storage box 5 is also extended.

[0037] The protruding support mechanism 3 includes a support plate 301, one end of the support plate 301 is connected to the control box 1 through a second torsion spring 302, a connecting block 303 is set through the middle of the support plate 301, the upper part of the connecting block 303 is detachably connected to the clip provided at the bottom of the support mounting frame 201, the lower part of the connecting block 303 is rotatably connected to one end of the first rotating rod 304, and the other end of the first rotating rod 304 is rotatably connected to the sliding rod 305, and the sliding rod 305 slides up and down in the control box 1.

[0038] In particular, the foot pedal unlocking mechanism 4 includes a foot pedal 401, an adjustment component and a hook-shaped limit block 402. The foot pedal 401 is set on the side wall of the control box 1 for sliding up and down. The bottom of the foot pedal 401 is rotatably connected to one end of the adjustment component, and the other end of the adjustment component is rotatably connected to the hook-shaped limit block 402. The hook-shaped limit block 402 is slidably set on the control box 1 and has a limiting function for the slide rod 305.

[0039] Specifically, the adjustment assembly includes a second rotating rod 403, a push rod 404, and a third rotating rod 405. One end of the second rotating rod 403 is connected to the bottom of the foot pedal 401, and the other end is rotatably connected to the front end of the push rod 404. After the push rod 404 passes through the control box 1, the end of the push rod 404 contacts the storage box 5. The front end of the push rod 404 is rotatably connected to one end of the third rotating rod 405. The middle portion of the third rotating rod 405 is rotatably mounted on the control box 1, and the other end of the third rotating rod 405 is rotatably connected to the hook-shaped limit block 402. Simultaneously, a second spring 406 is sleeved on the push rod 404, one end of which is fixed to the side wall of the control box 1. This ensures that during the movement of the push rod 404, the second spring 406 can provide a stable elastic restoring force, helping the push rod 404 to return to its original position and maintaining the stability and reliability of the foot unlocking mechanism 4.

[0040] In addition, debridement instruments 502 with different functions are inserted into the storage box 5, and the storage box 5 is connected to the control box 1 through a telescopic rod 501. The telescopic rod 501 ensures that the storage box 5 is stable when it is pushed out by the push rod 404, and ensures that the storage box 5 will not shake or tilt during the pushing and retracting process, thereby protecting the debridement instruments 502 from damage and facilitating medical staff to use them accurately.

[0041] When using this embodiment, before fixing the patient's limb, it is necessary to first open the support mechanism 3. When the support mechanism 3 is opened, first step on the foot pedal 401 downward, and the downward movement of the foot pedal 401 drives the second rotating rod 403 to slide downward. Since the second rotating rod 403 is restricted on the side wall of the control box 1, the second rotating rod 403 slides downward to push the push rod 404 to compress the second spring 406 and move toward the storage box 5, so as to push out the storage box 5. The storage box 5 slides out and stretches the telescopic rod 502, which is convenient for medical staff to take the debridement instruments 502 in the storage box 5 and retract the storage box 5. The push rod 404 compresses the second spring 406 and moves toward the storage box 5, driving the third rotating rod 405 to rotate around the midpoint. The third rotating rod 405 rotates to make the other end turn away When the second torsion spring 302 is in a compressed state, the reset of the second torsion spring 302 will drive the support plate 301 to rotate 90 degrees around the second torsion spring 302. The rotation of the support plate 301 will drive the connecting block 303 to rotate around the second torsion spring 302. At the same time, the connecting block 303 will also move upward. The upward movement of the connecting block 303 will drive the first rotating rod 304 to move upward. The first rotating rod 304 pulls the sliding rod 305 to slide upward along the control box 1, which can open the support mechanism 3 and facilitate the subsequent installation of the limb clamping mechanism 2. After use, the limb clamping mechanism 2 is removed, and the support plate 301 is manually rotated downward. The support plate 301 compresses the second torsion spring 302, and at the same time, the connecting block 303 and the first rotating rod 304 are rotated downward in sequence. The first rotating rod 304 pushes the slide bar 305 to slide downward along the control box 1, and the slide bar 305 slides downward to squeeze the hook-shaped limit block 402 to slide outward until the support mechanism 3 is completely retracted. At this time, the slide bar 305 is trapped in the hook-shaped limit block 402, and the hook-shaped limit block 402 tightly holds the slide bar 305 due to the reset function of the second spring 406. The specific holding principle is: when the support plate 301 is manually rotated downward to compress the second torsion spring 302 and return to the initial position, the slide rod 305 slides downward and squeezes the hook-shaped limit block 402 to slide outward. Due to the elastic restoring force of the second spring 406, the hook-shaped limit block 402 will automatically return to its original position after losing the squeezing of the slide rod 305, and tightly hold the slide rod 305, thereby completing the storage and locking of the support mechanism 3.

[0042] A usage process of this application is: 1. Preparation: After moving the operating room nursing debridement machine to the operating table, ensure that the brake wheel 103 of the control box 1 is locked to prevent the machine from moving during operation, check whether the debridement instruments 502 in the storage box 5 are complete, and ensure that the telescopic rod 501 is in good condition so that the storage box 5 can be smoothly pushed out and retracted.

[0043] 2. Open the support mechanism 3: The medical staff steps on the foot pedal 401 downward, and the foot pedal 401 pushes the hook-shaped limit block 402 to slide outward through the adjustment component (the second rotating rod 403, the push rod 404, and the third rotating rod 405), releasing the limit on the slide rod 305. Under the action of the second torsion spring 302, the support plate 301 rotates 90 degrees around the rotation axis of the second torsion spring 302, and at the same time drives the connecting block 303, the first rotating rod 304 and the slide rod 305 to move, and finally the support mechanism 3 is fully opened.

[0044] 3. Install the limb clamping mechanism 2: The clamping piece at the bottom of the support mounting frame 201 of the limb clamping mechanism 2 is detachably connected to the upper part of the connecting block 303 of the supporting mechanism 3 to ensure a stable connection.

[0045] 4. Fix the patient's limbs: The patient's arm is placed on the limb placement block 202. The weight of the limb causes the limb placement block 202 to compress the first spring 210 downward, triggering the transmission module (first rack 207, gear 208, second rack 209). The transmission module drives the rotating member 204, the sliding block 205 and the squeezing rod 206 to move, so that the limb clamping plate 203 automatically approaches the limb placement block 202, thereby automatically clamping the patient's limb.

[0046] 5. Adjust the exposure of the debridement site: According to the need for debridement, the first protective plate 211 and the second protective plate 212 on the limb clamping plate 203 are slid and adjusted, and the position is locked by the self-locking module (locking member 213, locking member 214, first torsion spring 215) to selectively expose the debridement area of ​​the patient's limb.

[0047] 6. Perform debridement: The medical staff takes out the necessary debridement instruments 502 from the storage box 5 and starts to perform debridement operations on the patient's arm, including cleaning, excision of necrotic tissue, hemostasis, suturing, drainage and bandaging.

[0048] 7. Operation completion and storage: After the debridement operation is completed, the limb clamping mechanism 2 is removed; Manually rotate the support plate 301 downward to compress the second torsion spring 302 and return it to its initial position. The hook-shaped limit block 402, under the action of the second spring 406, re-embraces the slide bar 305, completing the storage of the support mechanism 3. Push the storage box 5 back into the control box 1 .

[0049] Specific usage scenarios: In a hospital operating room, a patient with an open arm wound caused by an accident was rushed in. Medical staff quickly moved the operating room nursing debridement machine to the operating table. They stepped on the foot pedal 401, releasing the limit on the slide bar 305. The support mechanism 3 automatically unfolded, and the storage box 5 automatically extended. After opening the support mechanism 3 and installing the limb clamping mechanism 2, the patient's arm was securely fixed to the machine. The limb clamping mechanism 2 automatically clamped, and then selectively exposed the debridement site. The medical staff then removed the necessary debridement instruments from the storage box 5 and performed a thorough debridement on the patient's arm. The entire process was efficient and safe, not only reducing the workload of medical staff, but also improving the debridement effect and reducing the patient's pain and infection risk.
