[0058] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0059] like Figures 1-9 As shown, the present invention provides a technical solution: including a base 1, with casters mounted on the bottom of the base 1.

[0060] First motor housing 2, the first motor housing 2 is installed inside the base 1, and the first motor is installed inside the first motor housing 2;

[0061] Control mechanism 3 is located on the top of base 1. Control mechanism 3 includes receiving component 304 and feeding component 306. A first motor is used to control the rotation of receiving component 304 and feeding component 306.

[0062] Housing 4 is mounted on top of control mechanism 3, and a connecting rod is mounted on the bottom of housing 4;

[0063] The power mechanism 5 is installed inside the housing 4. The power mechanism 5 includes a sliding frame 504 and a locking assembly 508. The sliding member is used to control the movement of the locking assembly 508 and the cutting tool inside the locking assembly 508. There are two sliding frames 504, which are arranged symmetrically.

[0064] Before using the equipment, adjust the power mechanism 5 and the control mechanism 3, and install the tool in the locking assembly 508. Then adjust the position of the base 1, push the base 1 to the equipment usage location, turn on the control mechanism 3, adjust the direction of the power mechanism 5, and turn on the power mechanism 5 to perform tool position control.

[0065] Control mechanism 3 also includes:

[0066] The first rotating shaft 301 is connected to the output end of the first motor;

[0067] A connecting frame 303 is installed on the top of the first rotating shaft 301. One end of the connecting frame 303 is connected to the receiving assembly 304, and the other end of the connecting frame 303 is connected to the feeding assembly 306.

[0068] Support rod 302 is installed on the top of base 1, and an annular seat 305 is installed on the top of support rod 302;

[0069] Enclosure 307 is mounted on top of the annular seat 305;

[0070] The first push rod 308 is installed on the outside of the enclosure 307, and a protective plate 309 is installed on the outside of the first push rod 308.

[0071] The second motor housing 310 is installed inside the enclosure 307. The second motor is installed inside the second motor housing 310. The output end of the second motor is equipped with a second rotating shaft 311, which is connected to the housing 4.

[0072] An annular groove 312 is formed on the top of the second motor housing 310, and the connecting rod located at the bottom of the housing 4 moves in the annular groove 312.

[0073] When the loading and unloading of the cutting tools is required, the second motor in the second motor housing 310 is turned on. The second motor drives the second rotating shaft 311 to rotate, which in turn drives the housing 4 to rotate. The housing 4 then drives the internal power mechanism 5 to rotate. Subsequently, the first motor in the first motor housing 2 is turned on. The first motor drives the first rotating shaft 301 to rotate, which in turn drives the connecting frame 303 to rotate. The connecting frame 303 then drives the receiving assembly 304 and the feeding assembly 306 to rotate. By controlling the locking assembly 508, the receiving assembly 304, and the feeding assembly 306, the loading and unloading of the cutting tools is completed.

[0074] The receiving assembly 304 includes:

[0075] The first material cylinder 3041 is installed on the outside of the connecting frame 303. The top of the first material cylinder 3041 is provided with a groove 3042. Multiple grooves 3042 are provided and are evenly distributed.

[0076] The first base plate 3043 is installed at the bottom of the first material cylinder 3041, and the second push rod 3044 is installed at the top of the first base plate 3043.

[0077] Annular plate 3045, which is mounted on top of the second push rod 3044;

[0078] The protrusion 3046 is installed on the outside of the annular plate 3045. Multiple protrusions 3046 are provided and are evenly distributed. A suction strip is installed on the top of the protrusion 3046. The protrusion 3046 is correspondingly arranged with the groove 3042.

[0079] Before using the device, the second push rod 3044 is in the initial state, the protrusion 3046 is in the groove 3042, and the lower surface of the protrusion 3046 is in contact with the groove 3042. Manually put the disposable bag on the outside of the annular plate 3045 and press the edge of the bag so that the round edge of the bag is attracted to the suction strip.

[0080] As the locking assembly 508 releases the cutter, the cutter gradually enters the disposable bag inside the first material cylinder 3041. Then, the second push rod 3044 is activated, which drives the ring, protrusion 3046, suction strip, and disposable bag to move upward. The disposable bag can then be manually removed.

[0081] The used surgical instruments are received by the receiving component 304. The outer edge of the disposable bag is attracted and fixed by the protrusion 3046 and the suction strip to prevent the edge of the bag from entering the first material cylinder 3041 when the instrument descends. At the same time, the liftable annular plate 3045 moves the protrusion 3046 upward, which facilitates the upward movement of the disposable bag, thereby completing the work of picking up the disposable bag and the instrument inside.

[0082] The feeding assembly 306 includes:

[0083] The second material cylinder 3061 is installed outside the connecting frame 303. The side of the second material cylinder 3061 is provided with a through groove. There are two through grooves, which are arranged symmetrically.

[0084] The second base plate 3062 is installed at the bottom of the second material cylinder 3061, and the third push rod 3063 is installed at the top of the second base plate 3062.

[0085] The support plate 3064 is mounted on top of the third push rod 3063;

[0086] The third material cylinder 3065 is installed on top of the pallet 3064. There are two partitions 3066 installed inside the third material cylinder 3065.

[0087] Before using the equipment, the second material cylinder 3061 is at the bottom of the protective plate 309. As the connecting frame 303 moves the second material cylinder 3061 to directly below the locking assembly 508, the third push rod 3063 is activated. The third push rod 3063 drives the support plate 3064, the third material cylinder 3065, and the partition plate 3066 to rise to the highest position. The cutter is manually inserted into the two partition plates 3066. At this time, the bottom of the cutter is in the two partition plates 3066. The third push rod 3063 is adjusted to the initial state, and the third push rod 3063 drives the support plate 3064, the third material cylinder 3065, and the partition plate 3066 back to their original positions.

[0088] As the locking assembly 508 moves downward, the third push rod 3063 is activated. The third push rod 3063 drives the support plate 3064, the third material cylinder 3065, and the partition plate 3066 to rise to the highest position. The partition plate 3066 drives the cutter to rise, and the top of the cutter gradually gets into the locking assembly 508. As the locking assembly 508 drives the cutter to move upward, the cutter gradually disengages from the partition plate 3066.

[0089] By setting up the feeding assembly 306, the cutter inside the second material cylinder 3061 is protected from top by the protective plate 309 when the equipment is not in use. Before installing the cutter, the second material cylinder 3061 is staggered from the protective plate 309, so that the top of the second material cylinder 3061 is exposed. Under the control of the locking assembly 508 and the third push rod 3063, the cutter installation is completed, avoiding manual installation.

[0090] The power mechanism 5 includes:

[0091] The fourth push rod 501 is installed inside the housing 4, and a movable cylinder 502 is installed outside the fourth push rod 501.

[0092] The top of the movable cylinder 502 is provided with a slide groove 503, and the sliding frame 504 is slidably connected inside the slide groove 503. The sliding frame 504 is equipped with a power system inside.

[0093] The fifth push rod 507 is installed inside the slide groove 503 and is connected to the locking assembly 508;

[0094] The outer frame 505 is installed on the outside of the sliding frame 504. The first slider 506 is slidably connected inside the outer frame 505, and the power system is installed inside the first slider 506.

[0095] Telescopic rod 509 is installed outside the first slider 506. An mounting plate 510 is installed outside the telescopic rod 509. A contact is provided outside the mounting plate 510, and a pressure sensor is connected to the contact.

[0096] Spring 511 is installed inside the sliding frame 504. A sliding plate 512 is installed on the top of spring 511 and is slidably connected inside the sliding frame 504.

[0097] Before using the equipment, turn the fourth push rod 501 to the first stroke. The fourth push rod 501 drives the moving cylinder 502 to move outward. The moving cylinder 502 gradually moves directly above the first material cylinder 3041. Adjust the locking assembly 508. At this time, the disassembly and replacement of the tool can be completed.

[0098] Subsequently, driven by the second rotating shaft 311, the housing 4 and the moving cylinder 502 rotate in the opposite direction, and the fourth push rod 501 is adjusted to the corresponding stroke, so that the tool located at the center of the housing 4 is directly above the working position. The locking assembly 508 is adjusted to perform decompression orthopedic power surgery.

[0099] The card slot component 508 includes:

[0100] The second slider 5081 is installed at the bottom of the fifth push rod 507. The second slider 5081 is slidably connected to the inside of the sliding frame 504. The power system is installed inside the second slider 5081.

[0101] Link 5082 is installed outside the second slider 5081, and a sixth push rod 5083 is installed at the bottom of link 5082;

[0102] Clamping plate 5084 is installed at the bottom of the sixth push rod 5083. The clamping plate 5084 has a slot inside, the inside of the slot is made of rubber, and the top of the slot gradually narrows from bottom to top.

[0103] Adjusting column 5085 is installed on the outside of connecting rod 5082;

[0104] Contact plate 5087 is installed outside of adjusting column 5085, and contact block 5086 is installed at the bottom of contact plate 5087.

[0105] Before installing the tool, turn on the power system in the two sliding brackets 504. The two sliding brackets 504 gradually approach each other, which in turn drives the two clamping plates 5084 to gradually approach and make contact. Turn the two sixth push rods 5083 to their maximum stroke. The two sixth push rods 5083 drive the two clamping plates 5084 to move downwards until the tool is engaged in the slots in the two clamping plates 5084. As the top of the slot gradually narrows from bottom to top, the top of the tool gradually engages in the slot, and the inside of the slot undergoes slight deformation, fixing the position of the tool.

[0106] When the tool needs to be released, the two sixth push rods 5083 are activated to their maximum stroke. The two sixth push rods 5083 drive the two clamping plates 5084 to move downward. Then the power system is activated to control the two sliding frames 504 to move in opposite directions, and the tool gradually falls into the first material cylinder 3041.

[0107] Before using the equipment, adjust the sixth push rod 5083 to the first stroke. The sixth push rod 5083 drives the clamping plate 5084 downward to a position flush with the bottom of the outer frame 505. Adjust the stroke of the fifth push rod 507 so that the tool finally lands at the cutting position. Adjust the power system in the first slider 506. The first slider 506 moves inside the outer frame 505. When the fifth push rod 507 drives the tool to the cutting position, the contact block 5086 contacts the contact point on the outside of the mounting plate 510. The contact point transmits a signal to the pressure sensor. The pressure sensor transmits a signal to the power system. The power system controls the fifth push rod 507 to move upward, causing the tool to retract and perform the tool self-limiting operation.

[0108] The position of the cutting tool is controlled by the power mechanism 5 and the locking assembly 508. The cutting tool is clamped and released by two movable sliding frames 504 and two clamping plates 5084 with slots. The locking assembly 508, in conjunction with the receiving assembly 304 and the feeding assembly 306, completes the disassembly and installation of the cutting tool. When the cutting tool contacts the cutting position, the contact block 5086 contacts the contact point, transmitting a signal to the power system to control the cutting tool retraction, thus performing a self-limiting operation.

[0109] Working principle: Before using the equipment, adjust the power mechanism 5 and the control mechanism 3 to install the tool in the clamping assembly 508.

[0110] Before using the equipment, turn the fourth push rod 501 to the first stroke. The fourth push rod 501 drives the moving cylinder 502 to move outward. The moving cylinder 502 gradually moves directly above the first material cylinder 3041. Adjust the locking assembly 508. At this time, the disassembly and replacement of the tool can be completed.

[0111] Before using the device, the second push rod 3044 is in the initial state, the protrusion 3046 is in the groove 3042, and the lower surface of the protrusion 3046 is in contact with the groove 3042. Manually put the disposable bag on the outside of the annular plate 3045 and press the edge of the bag so that the round edge of the bag is attracted to the suction strip.

[0112] When the tool needs to be released, the two sixth push rods 5083 are activated to their maximum stroke. The two sixth push rods 5083 drive the two clamping plates 5084 to move downward. Then the power system is activated to control the two sliding frames 504 to move in opposite directions, and the tool gradually falls into the first material cylinder 3041.

[0113] As the locking assembly 508 releases the cutter, the cutter gradually enters the disposable bag inside the first material cylinder 3041. Then, the second push rod 3044 is activated, which drives the ring, protrusion 3046, suction strip, and disposable bag to move upward. The disposable bag can then be manually removed.

[0114] Before using the equipment, the second material cylinder 3061 is at the bottom of the protective plate 309. As the connecting frame 303 moves the second material cylinder 3061 to directly below the locking assembly 508, the third push rod 3063 is activated. The third push rod 3063 drives the support plate 3064, the third material cylinder 3065, and the partition plate 3066 to rise to the highest position. The cutter is manually inserted into the two partition plates 3066. At this time, the bottom of the cutter is in the two partition plates 3066. The third push rod 3063 is adjusted to the initial state, and the third push rod 3063 drives the support plate 3064, the third material cylinder 3065, and the partition plate 3066 back to their original positions.

[0115] Before installing the cutting tool, activate the power system in the two sliding frames 504. The two sliding frames 504 gradually approach each other, which in turn causes the two clamping plates 5084 to gradually approach and make contact. Activate the two sixth push rods 5083 to their maximum stroke, causing the two sixth push rods 5083 to move the two clamping plates 5084 downwards.

[0116] As the positioning assembly 508 moves downward, the third push rod 3063 is activated. The third push rod 3063 drives the support plate 3064, the third material cylinder 3065, and the partition plate 3066 to rise to their highest positions. The partition plate 3066 drives the tool to rise until the tool is engaged in the slots within the two clamping plates 5084. As the top of the slot gradually narrows from bottom to top, the top of the tool gradually engages in the slot, causing a slight deformation inside the slot to fix the tool's position. The sixth push rod 5083 is then adjusted to its initial state, and the positioning assembly 508 drives the tool to move upward, gradually disengaging the tool from the partition plate 3066.

[0117] Then adjust the position of base 1, push base 1 to the equipment usage location, activate control mechanism 3, adjust the direction of power mechanism 5, and activate power mechanism 5 to perform tool position control.

[0118] Before using the equipment, adjust the sixth push rod 5083 to the first stroke. The sixth push rod 5083 drives the clamping plate 5084 downward to a position flush with the bottom of the outer frame 505. Adjust the stroke of the fifth push rod 507 so that the tool finally lands at the cutting position. Adjust the power system in the first slider 506. The first slider 506 moves inside the outer frame 505. When the fifth push rod 507 drives the tool to the cutting position, the contact block 5086 contacts the contact point on the outside of the mounting plate 510. The contact point transmits a signal to the pressure sensor. The pressure sensor transmits a signal to the power system. The power system controls the fifth push rod 507 to move upward, causing the tool to retract and perform the tool self-limiting operation.
