[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example 1, as Figures 1 to 11As shown, the intraoperative wound cleaning device for clinical orthopedics of the present invention includes a box body 1, the box body 1 includes a collection box 12 arranged at the bottom, a table 11 is arranged above the collection box 12, a cleaning gun 2 is placed on the upper end surface of the table 11, a gun head 4 is installed at the muzzle position of the cleaning gun 2, and a gun head replacement module 5 and a gun head storage module 3 are arranged on the lower end surface of the table 11.

[0022] Specifically, when the gun head 4 of the cleaning gun 2 needs to be replaced, hold the cleaning gun 2 with the gun head of the cleaning gun 2 facing the table 11, and then insert the head of the cleaning gun 2 into the center hole of the table 11, and then press down the cleaning gun 2. At this time, the old gun head 4 installed at the front end of the cleaning gun 2 will be automatically removed, and the removed old gun head 4 will fall into the collection box 12. Continue to press down the cleaning gun 2 to drive the gun head replacement module 5 to work. The gun head replacement module 5 will bring the new gun head taken out from the gun head storage module 3 to the bottom of the muzzle of the cleaning gun 2. Continuing to press down the cleaning gun 2 will connect the new gun head to the cleaning gun 2, and then take out the cleaning gun 2 to complete the gun head replacement.

[0023] Example 2, as Figure 3 、 Figure 4 As shown, the intraoperative wound cleaning device for clinical orthopedics of the present invention includes a cleaning gun 2. The gun body of the cleaning gun 2 includes a gun barrel 21, a grip 22 and a trigger 23. A water suction pipe 24 and a flushing pipe 25 are provided inside the cleaning gun 2. The muzzle position of the gun barrel 21 is provided with a gun head clamping module 6 and a gun head disassembly module 7.

[0024] Specifically, when in use, hold the handle 22 and pull the trigger 23 to start the negative pressure pump and water outlet pump inside the gun body. The cleaning liquid cleans the wound through the flushing pipe 23, and the dirty water after cleaning is sucked away by the suction pipe 24, forming a cleaning cycle. When the gun head needs to be replaced, the gun head is removed by triggering the gun head clamping module 6 and the gun head disassembly module 7, and then the new gun head is installed and clamped by the gun head clamping module 6.

[0025] Example 3, as Figure 4 、 Figure 6 As shown, the intraoperative wound cleaning device for clinical orthopedics of the present invention includes a gun head clamping module 6, which includes a pull rod 62 slidably installed inside the gun barrel 21, and a spring is connected between the pull rod 62 and the gun barrel 21, one end of the pull rod 62 close to the muzzle is hinged with a first connecting rod 63, and a torsion spring is connected to the hinge position of the pull rod 62 and the moving block 61, the other end of the pull rod 62 is hinged with the moving block 61, and the other end of the first connecting rod 63 is hinged to a limit block 64, the limit block 64 is slidably installed inside the gun barrel 21, and a spring is connected between the limit block 64 and the gun barrel 21.

[0026] Specifically, when the gun head needs to be replaced, the moving block 61 is driven to move, the moving block 61 drives the pull rod 62 to move, the pull rod 62 drives the first connecting rod 63 to move, and the movement of the first connecting rod 63 drives the limit block 64 to move. The movement of the limit block 64 will contact the clamping connection of the gun head, and then the gun head can be detached from the cleaning gun.

[0027] Example 4, as Figure 7 As shown, the intraoperative wound cleaning device for clinical orthopedics of the present invention includes a gun tip disassembly module 7, which includes a movable plate 71 slidably installed inside the gun barrel 21, and a second connecting rod 72 is hinged at the bottom end of the movable plate, and a disassembly rod 73 is hinged at the other end of the second connecting rod 72. The disassembly rod 73 is connected to the gun barrel 21 in a transverse sliding manner, and a spring is connected between the disassembly rod 73 and the gun barrel 21.

[0028] Specifically, when the gun head needs to be replaced, the moving block 61 is first driven to release the clamping of the limit block 64 on the gun head. At this time, the moving block 61 moves to the rounded corner position on its right side. Since the moving block 61 and the pull rod 62 are hinged, the moving block 61 can flip around the rounded corner at this time. After the limit block 64 releases the limit, it continues to drive the moving block 61 to flip it. The downward flipping of the moving block 61 will press the moving plate 71 downward to move it. The movement of the moving plate 71 will drive the second connecting rod 72. The movement of the second connecting rod 72 will drive the disassembly rod 73 to move toward the gun head. Since the front end of the disassembly rod 73 is in contact with the gun head, the movement of the disassembly rod 73 will push the gun head, thereby causing the gun head to detach from the cleaning gun, completing the disassembly of the gun head.

[0029] Example 5, as Figure 9 、 Figure 10 As shown, the intraoperative wound cleaning device for orthopedic clinical use of the present invention includes a gun tip replacement module 5, which includes two sets of trigger plates 51 arranged symmetrically. The trigger plates 51 are slidably mounted on the bottom end of the table 11. A driving rack 511 is fixedly connected to one side of the trigger plate 51. A first gear 52 is provided at a position where the tooth surface of the driving rack 511 faces the first gear 52. The first gear 52 is rotatably connected to the table 11 and meshes with the driving rack 511. A second gear 53 is provided at a position away from the first gear 52 and the trigger plate 51. The second gear 53 is rotatably connected to the table 11 and meshes with the second gear 52. The trigger plate 51, the first gear 52, and the second gear 53 are symmetrically arranged in two groups. The bottom ends of the two second gears 53 are fixedly connected to the first connecting shaft 54 and the second connecting shaft 541 respectively. The bottom end of the first connecting shaft 54 is provided with a replacement rack 55 through a sliding key sleeve. The bottom end of the second connecting shaft 541 is fixedly connected to a rotating baffle 56. The column 121 is rotatably connected to the bottom of the replacement rack 55, and the bottom end of the column 121 is fixedly connected to the collection box 12.

[0030] Specifically, when there is no need to replace the gun head and only self-cleaning is needed, the cleaning gun 2 only needs to be placed in the center hole of the table 11 without pressing down. At this time, the rotating baffle 56 is directly below the gun head 4. At this time, the trigger of the cleaning gun can be pulled. The cleaning liquid will be sucked away by the suction pipe of the cleaning gun 2 due to the obstruction of the rotating baffle 56, so that the clean cleaning liquid will enter the water suction pipe 24, thereby cleaning the water suction pipe and realizing self-cleaning of the cleaning gun 2.

[0031] When the gun tip needs to be replaced, the gun tip of the cleaning gun 2 is inserted into the center hole of the table 11. When the handheld cleaning gun 2 is pressed down, the upper table 11 will push the moving block 61 to move first. During this process, the limit block 64 will first push the upper half of the trigger plate 51 to move the trigger plate 51 a certain distance. At this time, the trigger plate 51 drives the driving rack 511 to move synchronously, and the driving rack 511 drives the first gear 52 to rotate. The rotation of the first gear 52 drives the second gear 53 to rotate. The two second gears 53 respectively drive the first connecting shaft 54 and the second connecting shaft 541 to rotate. The first connecting shaft 54 drives the replacement frame 55 to rotate toward the center by a certain angle ( Figure 10 The middle replacement frame 55 rotates counterclockwise by a certain angle), the second connecting shaft 541 drives the rotating baffle 56 to rotate away from the center by a certain angle ( Figure 10 When the cleaning gun 2 is cleaned, the cleaning rod 73 is reset under the action of the spring, the movable block 61 is reset under the action of the torsion spring, and the limit block 64 is reset under the action of the spring, so that the limit block 64 can realize the clamping of the gun head. At this time, the gun head replacement is completed and the cleaning gun 2 can be taken out.

[0032] Example 6, as Figure 8 、 Figure 11 As shown, the intraoperative wound cleaning device for clinical orthopedics of the present invention includes a gun tip storage module 3, and the gun tip storage module 3 includes a placement rack 31 fixedly connected to the lower end surface of the table 11, and multiple gun tips 4 are placed inside the placement rack 31. The placement rack 31 is slidably connected to the side away from the gun tip 4 with a pull rod 33, and the pull rod 33 is fixedly connected to the end close to the gun tip with a feed push plate 32, and a spring is connected between the feed push plate 32 and the placement rack 31, and the placement rack 31 is slidably connected to the lower end away from the pull rod 33 with a limiting module 34.

[0033] Specifically, when a new gun head is to be added, the feed push plate 32 is pulled by the pull rod 33, and then multiple new gun heads are placed into the placement rack 31 from the end of the placement rack 31, and then the pull rod 33 is released. At this time, the feed push plate 32 will move toward the replacement rack 55 under the action of the spring, pushing the new gun head toward the replacement rack 55, which is convenient for the next replacement.

[0034] Example 7, as Figure 5 As shown, the intraoperative wound cleaning device for clinical orthopedics of the present invention includes a gun head 4, which includes a connecting block 43 arranged at one end thereof, a connecting groove 431 is opened on the side of the connecting block 43, and a water outlet connector 41 and a water suction connector 42 are provided on the end face of the connecting block 43. The other end of the gun head 4 is provided with a water outlet cover 44.

[0035] Specifically, when the gun head 4 is connected to the cleaning gun 2, the water outlet connector 41 and the water suction connector 42 are first interference fit with the ends of the flushing pipe 25 and the water suction pipe 24 inside the cleaning gun 2 to ensure a certain degree of sealing. Then the limit block 64 inside the cleaning gun 2 can be clamped into the connecting groove 431 opened on the side of the connecting block 43, and the water outlet cover 44 at the end of the gun head can prevent the cleaning liquid from splashing during cleaning.

[0036] Example 8, as Figures 9 to 11 As shown, the intraoperative wound cleaning device for clinical use of the present invention includes a replacement rack 55. A slot 553 is provided at a position of the replacement rack 55 away from the first connecting shaft 54. The upper end surface of the replacement rack 55 is slidably connected to a limiting spring block 552. A spring is connected between the limiting spring block 552 and the replacement rack 55. The replacement rack 55 is fixedly connected to an abutment block 551 on the outward side.

[0037] Specifically, after the gun head 4 enters the slot 553 opened on the replacement rack 55, the angle of the gun head 4 is guaranteed under the action of the limiting spring block 552. Since a spring is connected between the limiting spring block 552 and the replacement rack 55, when the cleaning gun 2 is moved to the position of the gun head 4, the limiting spring block can be pressed down without affecting the normal installation of the gun head.

[0038] Example 9, as Figure 11 As shown, in the orthopedic clinical intraoperative wound cleaning device of the present invention, the limiting module 34 includes a limiting baffle 342 slidably mounted on the bottom end of the placement frame 31, and the limiting baffle 342 is fixedly connected to the limiting rod 341 through a connecting plate.

[0039] Specifically, when the placement rack 55 is in the initial state ( Figure 11As shown in the state shown), the abutting fastener 551 at the bottom of the placement rack abuts against the limiting rod 341 of the limiting module 34. When the placement rack 55 rotates, the abutting fastener 551 gradually leaves the limiting rod 341, and the limiting baffle 342 blocks the outlet of the placement rack 31 under the action of the spring to prevent the subsequent gun head from being pushed out by the feed push plate 32.

[0040] Example 10, as Figure 8 As shown, the intraoperative wound cleaning device for clinical orthopedics of the present invention is provided with a placement hole 111 at the center of the upper end surface of the table 11, and two sets of hinged plates 112 are provided on the upper end of the side of the placement hole 111. The hinged plates 112 are hinged to the table 11 and a torsion spring is provided at the hinge position.

[0041] Specifically, when the cleaning gun 2 is inserted into the placement hole 111, the moving block 61 contacts the hinged plate 112 and continues to press down the cleaning gun. The moving block 61 will move and flip under the obstruction of the hinged plate 112. When the moving block 61 moves to the bottom of the hinged plate 112, the new gun head has been inserted into the front end of the cleaning gun 2. Then the moving block 61 is reset under the action of the torsion spring and the spring, so that the gun head 4 and the cleaning gun 2 are connected together. Then the cleaning gun 2 is lifted out of the moving block 61 and passes through the hinged plate 112, so that the hinged plate 112 flips upward and then leaves the placement hole 111 to complete the gun head replacement.

[0042] Working principle: After the wound is cleaned with the handheld cleaning gun 2, if the gun head is blocked or only needs to be temporarily placed, just hold the cleaning gun 2 and insert the gun head into the placement hole 111 of the table 11 without pressing down, and then pull the trigger 23. At this time, the cleaning liquid rushes to the rotating baffle 56 through the flushing pipe 25, and is then sucked away by the suction pipe 24, thereby cleaning the inside of the suction pipe 24.

[0043] When the gun head needs to be replaced, the cleaning gun 2 is held in the hand and inserted into the placement hole 111 of the table 11. The moving block 61 first contacts the hinged plate 112, and then the cleaning gun 2 is pressed down. The moving block 61 will move relative to the cleaning gun 2 due to the obstruction of the hinged plate 112. The movement of the moving block 61 will drive the first connecting rod 63 through the pull rod 62. The movement of the first connecting rod 63 will push the limit block 64 outward. The ejection of the limit block 64 will unlock the restriction on the old gun head and push the upper half of the trigger plate 51 to move a certain distance. The movement of the trigger plate 51 will drive the first gear 52 to rotate through the driving rack 511. The first gear 52 drives the second gear 53 to rotate. The second gear 53 drives the replacement rack 55 and the rotating baffle 56 to rotate respectively through the first connecting shaft 54 and the second connecting shaft 541. At a certain angle, the rotating baffle 56 is no longer directly under the old gun head. At this time, the moving block 61 moves to the extreme position relative to the cleaning gun 2, and a groove is opened on its right side. Continue to press down on the cleaning gun 2. At this time, the moving block 61 will flip into the groove under the obstruction of the hinged plate 112. After flipping, the moving block 61 will press the moving plate 71 to move it downward. The movement of the moving plate 71 drives the disassembly rod 73 to move toward the gun head through the second connecting rod 72. The movement of the disassembly rod 73 will disassemble the gun head, and the disassembled gun head will fall into the collection box 12.

[0044] After the old gun head is removed, continue to press down on the cleaning gun 2. The lower half of the trigger plate 51 will be pushed by the limit block 64 to continue moving a certain distance. The trigger plate 51 continues to move and will rotate the replacement rack 55 to the bottom of the cleaning gun 2 through the driving structure. Continue to press down on the cleaning gun 2 to install the gun head into the cleaning gun. In this process, the moving block 61 moves to the bottom of the hinged plate 112. At this time, the disassembly rod 73 is reset under the synchronous action of the gun head and the spring. The disassembly rod 73 drives the moving plate 71 to reset through the second connecting rod 72. The moving plate 61 is not blocked by the hinged plate 112 and is pushed open and reset. Then the limit block 64 is also reset under the action of the limit block. At this time, the limit block enters the connecting groove 431 at the front end of the gun head 4 to clamp the gun head. At this time, lift the cleaning gun 2 and the gun head replacement is completed.

[0045] After the cleaning gun 2 is pulled out, the trigger plate 51 is reset, and the replacement rack 55 and the rotating baffle 56 are also reset. When the replacement rack 55 rotates back to the initial position, the abutment block 551 will gradually push open the limit rod 341 at the front end of the placement rack 31, and the limit rod 341 drives the limit baffle 342 to synchronously open the limit for the new gun head. When the notch 553 and the prevention mouth of the placement rack 31 are aligned, the feed push plate 32 will push a new gun head into the notch 553 under the action of the spring, which is convenient for the next replacement.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
