[0015] In order to solve the above technical problems, the present invention also provides an orthopedic nail removal method, comprising the following steps: S1: Place the patient on the operating table and ensure the patient is positioned properly for surgery. S2: The patient is anesthetized, the threaded bolt is unscrewed, the surgical frame is adjusted so that the screw head is in a suitable position for extracting the bone screw, and the threaded bolt is inserted to fix the position of the surgical frame; S3: Cut the skin and subcutaneous tissue along the original surgical incision, start the first motor, and drive the second screw down via the belt so that the bottom end of the screw head is inserted into the cross slot at the top of the bone screw. Turn off the first motor and check whether a suction device is needed to remove blood and exudate. S4: The first motor is started again to drive the second screw to rotate and raise the mounting base. As the mounting base rotates and rises, the bone screw is gradually screwed out of the patient's body.
[0016] Compared with related technologies, the orthopedic nail removal device provided by the present invention has the following beneficial effects: The present invention provides an orthopedic nail removal device, which cooperates with a positioning hole, a threaded bolt, an adjustment plate, a surgical frame, a first screw rod and a round-edged hand wheel. Due to the complex human bone structure, the implantation angle and depth of bone screws in different parts of the body are different. The adjustable angle and position can help doctors in some parts of complex anatomical structures, such as near joints and spine, to more conveniently reach the bone nail position and perform operations, thereby improving the success rate of the operation; through the cooperation of a first motor, a belt, a limiting cylinder, a cylinder body, a second screw rod, a lifting plate, a mounting seat, a limiting protrusion, a limiting groove, a nail removal head and a bone nail clamp, in the process of extracting the bone nail, especially in some deeper parts or bone nails that are difficult to directly observe, the bone nail clamp continues to rise and contacts the inner wall of the cylinder, The two bone screw clamps move relative to each other to stably clamp the bone screw, preventing the screw from accidentally loosening and falling into surrounding tissue during the screwing-out process, which would increase the complexity and risk of the operation. Secondly, the bone screw clamps can better fix the bone screw, allowing the doctor to more accurately control the movement direction and force of the bone screw when rotating and extracting it, reducing damage to surrounding bone and soft tissues. The first water pump, the nozzle, and the second box work together to promptly flush away impurities such as bone chips and tissue debris generated during the screw removal process, maintaining a clear surgical field of view, facilitating accurate operation by the doctor, and also helping to reduce the risk of postoperative infection. Secondly, when removing the screw, heat may be generated due to friction between the instrument and the bone screw. Spraying physiological saline can cool the area and prevent local tissue from being damaged by overheating. The present invention provides an orthopedic nail removal device. The nail-dropping cylinder, a first row of nail tubes, a rotating disk, a second motor, a dial, a groove wheel and a first connecting rod cooperate with each other. The rotating disk can place multiple bone nails and can rotate intermittently to make the bone nails fall into the holes one by one. In this way, the removed bone nails can be collected in an orderly manner. After the bone nails fall into the holes, they can be immediately immersed in a cleaning liquid to achieve timely cleaning, prevent tissue debris, blood and the like on the bone nails from drying up, reduce the difficulty of subsequent cleaning, effectively remove bacteria and contaminants carried on the surface of the bone nails, and reduce their retention time in the surgical area. The risk of cross infection is reduced. Through the cooperation of the first spring, movable rod, bone nail clamp, triangular block, floating plate, floating rod, fixed cylinder, waterproof rod, separation cylinder, ultrasonic transducer, one-way valve, second water pump and hard pipe, the bone nail automatically drops from the rotating disk to the next processing step after cleaning is completed, without manual operation. When the bone nail is soaked in the cleaning liquid for a sufficient time and the cleaning liquid level drops, the two bone nail clamps release the bone nail and make it fall, thereby ensuring the cleaning effect while avoiding surface damage or other adverse effects caused by excessive cleaning of the bone nail. The present invention provides an orthopedic nail removal device, which cooperates with a spray pipe, a water supply pipe, a third water pump, a water extraction pipe, a fourth motor, a rotating rod, a second spring, a rectangular block, a bone nail collection tray, a water collection tray and a drain pipe. Since most impurities on the surface of the soaked bone nails have been softened or removed, some fine residues still remain. The bone nails can be cleaned again with flowing clean water or a specific flushing liquid. When the bone nail collection tray rotates, the bone nails are better exposed to the clean water, thereby improving the cleanliness of the bone nails. Cleaning liquid will remain on the surface of the soaked bone nails. Some cleaning liquids may be irritating to the human body or affect the subsequent detection and storage of the bone nails. The clean water sprayed by the spray pipe can effectively remove these residues, thereby avoiding potential adverse effects.
[0017] The present invention provides an orthopedic nail removal method. By adopting the above-mentioned orthopedic nail removal device to remove the bone nails, the removal of the bone nails is greatly facilitated, which is beneficial to preventing the bone nails from loosening and falling off, and avoiding the bone nails from accidentally loosening and falling into the surrounding tissues during the screwing-out process, thereby increasing the complexity and risk of the operation.

The limiting protrusion 23 is slidably installed in the limiting groove 24, and the first motor 6 is started. The output shaft of the first motor 6 drives the limiting cylinder 16 to rotate through the belt 15, and the limiting cylinder 16 drives the second screw rod 12 to rotate. When the second screw rod 12 rotates, it drives the mounting seat 20 to rise and fall because it is threadedly connected to the cylinder body 7. The bottom of the mounting seat 20 is fixedly installed with a nail head 19, and the outer wall of the mounting seat 20 is rotatably installed with a lifting plate 21, and the lifting plate 21 is slidably installed in the cylinder body 7.

A second motor 51 is fixedly installed in the immersion chamber 45, and a dial 52 is fixedly installed on the output shaft of the second motor 51. A protrusion is fixedly installed on the bottom of the dial 52, and the protrusion is adapted to the plurality of linkage grooves. When the second motor 51 is started, the output shaft of the second motor 51 drives the dial 52 to rotate. When the dial 52 rotates, it drives the rotating disk 36 to rotate indirectly through the groove wheel 50. When the rotating disk 36 rotates intermittently, the bone screws can be placed in specific positions in sequence to avoid chaotic accumulation of the bone screws, which leads to poor cleaning of some tissues and other impurities during cleaning. After cleaning, the bone screws can be discharged one by one in an orderly manner through intermittent rotation.
[0030] A one-way valve 32 is fixedly installed at the water outlet end of the second water pump 31 , and one end of the one-way valve 32 away from the second water pump 31 is fixedly connected to the first box 2 .
[0031] After the bone screw is taken out of the patient's body, the second motor 51 is started. The output shaft of the second motor 51 drives the dial 52 to rotate. When the dial 52 rotates, it drives the rotating disk 36 to rotate indirectly through the groove wheel 50, and the bone screw is dropped into the nail-dropping barrel 25. When the placement port rotates to the bottom of the first row of nail tubes 28, the bone screw falls into the placement port from the first row of nail tubes 28. The two bone screw clamps 49 contact the bottom of the bone screw cap and restrict the bone screw to prevent it from falling. Then the second water pump 31 is turned on. The second water pump 31 pumps the cleaning liquid containing enzymes in the third box 26 into the immersion chamber 45 through the hard pipe 30. Through continuous extraction, the cleaning liquid submerges the third box 26. The second water pump 31 is turned off, and the bone screw is immersed in the cleaning liquid. At this time, the ultrasonic transducer 35 is turned on. The high-frequency vibration generated by the ultrasonic transducer 35 forms countless tiny bubbles in the cleaning liquid. When these bubbles burst on the surface of the bone screw, they will generate a strong impact force, which can effectively remove dirt, bacteria, etc. on the surface of the bone screw and in the gaps. After the preliminary cleaning is completed, the second water pump 31 is turned on again. The second water pump 31 pumps the cleaning liquid in the immersion chamber 45 into the third box body 26. When the cleaning liquid level in the immersion chamber 45 drops, the cleaning liquid in the fixed cylinder 46 and the separation cylinder 48 will flow out from the drainage hole. Then the cleaning liquid drives the float plate 44 to drop, so that the bottom of the float rod 43 contacts the pressure sensor 60, and the third motor 57 is triggered to turn on, driving the second connecting rod 59 to rotate through the output shaft. The second connecting rod 59 drives the isolation plate 61 to rotate ninety degrees, and the float plate 44 is at the bottom. When the screwdriver is lowered, the triangular block 42 is lowered, so that the bottom of the triangular block 42 contacts the top of the rotating disk 36. When the rotating disk 36 rotates and the placement port is located at the top of the separation cylinder 48, the two movable rods 33 contact the triangular block 42 and are squeezed to both sides by the triangular block 42. The two bone nail clamps 49 move away from each other and no longer clamp the bone nails. The bone nails fall into the separation cylinder 48 and fall from the second row of nail tubes 39 into the bone nail collection tray 38. After all the bone nails on the rotating disk 36 fall onto the bone nail collection tray 38, the third motor 57 is started to rotate the isolation plate 61 another 90 degrees, and then the second water pump 31 is turned on again to pump the cleaning liquid into the immersion chamber 45. When it is necessary to remove impurities such as tissue in the third box 26, the drain valve 29 on one side can be opened. Through the arrangement of the above components, the rotating disk 36 can hold multiple bone screws, and can rotate intermittently to make the multiple bone screws on the rotating disk 36 fall into the holes one by one, so that the removed bone screws can be collected in an orderly manner, and the bone screws can be immediately immersed in the cleaning liquid after falling into the holes, so as to achieve timely cleaning, prevent tissue debris, blood, etc. on the bone screws from drying up, reduce the difficulty of subsequent cleaning, effectively remove bacteria and pollutants carried on the surface of the bone screws, reduce their retention time in the surgical area, and reduce the risk of cross infection. After the cleaning is completed, the bone screws automatically fall from the rotating disk 36 to the next processing link without manual operation. When the bone screws are soaked in the cleaning liquid for a sufficient time, the cleaning liquid level drops, and the two bone screw clamps 49 loosen the bone screws to make the bone screws fall, ensuring the cleaning effect while.Avoid excessive cleaning of the bone screws that may cause surface damage or other adverse effects.

The water inlet end of the pump 56 is fixedly connected, and a water collecting tray 37 is fixedly installed in the flushing chamber 27. A drain pipe 53 is fixedly installed on one side of the water collecting tray 37, and one end of the drain pipe 53 extends to the outside of the first box body 2. A rectangular column is fixedly installed in the bone screw collection tray 38, and a first rectangular groove is provided on the top of the rectangular column. A fourth motor 62 is fixedly installed on the top inner wall of the flushing chamber 27, and a rotating rod 65 is fixedly installed on the output shaft of the fourth motor 62. A second rectangular groove is provided at one end of the rotating rod 65 close to the rectangular column, and a rectangular block 63 is slidably installed in the second rectangular groove. A toggle rod is fixedly installed on one side of the rectangular block 63, and one end of the toggle rod extends to the outside of the rotating rod 65.
[0035] A plurality of arc-shaped support bars are provided in the water collecting tray 37 , and the bottom of the bone screw collecting tray 38 is in contact with the plurality of arc-shaped support bars, so that the water on the bone screw collecting tray 38 can quickly drip into the water collecting tray 37 through the arc-shaped support bars.
[0036] The rectangular block 63 is adapted to the first rectangular groove, and the bottom end of the rectangular block 63 extends into the first rectangular groove. One end of the second spring 64 is fixedly installed on the top of the rectangular block 63, and the other end of the second spring 64 is fixedly connected to the second rectangular groove. The rectangular block 63 cooperates with the first rectangular groove. When the fourth motor 62 is started, the rotating rod 65 can drive the bone screw collection tray 38 to rotate through the rectangular block 63.
[0037] When all the bone screws have fallen onto the bone screw collecting tray 38, the fourth motor 62 is started, and the output shaft of the fourth motor 62 drives the rotating rod 65 to rotate, and the rotating rod 65 drives the bone screw collecting tray 38 to rotate through the rectangular block 63, and the third water pump 56 is turned on. The third water pump 56 draws clean water from the second box 11 through the water pumping pipe 55, and delivers it to the spray pipe 58 through the water delivery pipe 54. The spray pipe 58 starts to rinse the bone screws on the bone screw collecting tray 38, and the clean water after cleaning is discharged through the drain pipe 53. When it is necessary to take out the bone screws, the sealed door on one side of the first box 2 is opened, and the lever is lifted upward to move the rectangular block 63 away from the first rectangular recess. The bone screw collection tray 38 can be taken out of the groove. Through the arrangement of the above components, the present invention can use flowing clean water or a specific flushing liquid to clean the bone screw again because most of the impurities on the surface of the soaked bone screw have been softened or removed. When the bone screw collection tray 38 rotates, the bone screw can be better exposed to the clean water, thereby improving the cleanliness of the bone screw. Cleaning liquid will remain on the surface of the bone screw after soaking. Some cleaning liquids may be irritating to the human body or affect the subsequent detection and storage of the bone screw. The clean water sprayed by the spray pipe 58 can effectively remove these residues and avoid potential adverse effects.
