The disposable bag is manually placed on the outside of the annular plate 3045, and the edge of the bag is pressed so that the round edge of the bag is sucked into the suction strip.

[0026] As the positioning assembly 508 releases the cutter, the cutter gradually enters the disposable bag in the first barrel 3041. Then, the second push rod 3044 is opened, and the second push rod 3044 drives the ring, the protrusion 3046, the suction strip and the disposable bag to move upward, and then the disposable bag can be manually taken out.

[0027] The material receiving assembly 304 is provided to receive used surgical tools. The outer edge of the disposable bag is fixed by a protrusion 3046 and a suction strip to prevent the bag edge from following the tool into the first barrel 3041 when the tool is lowered.

[0033] Before using the equipment, open the fourth push rod 501 to the first stroke, the fourth push rod 501 drives the movable cylinder 502 to move outward, and the movable cylinder 502 is gradually located directly above the first barrel 3041. Adjust the positioning assembly 508, and the tool can be disassembled and replaced at this time.

[0034] Then, driven by the second rotating shaft 311, the housing 4 and the movable cylinder 502 rotate in opposite directions, and the fourth push rod 501 is adjusted to the corresponding stroke, so that the tool at the center of the housing 4 is directly above the working position. The positioning assembly 508 is adjusted to perform decompression orthopedic dynamic surgery.

[0035] The latch assembly 508 includes: The second slider 5081 is mounted on the bottom of the fifth push rod 507. The second slider 5081 is slidably connected to the interior of the sliding frame 504. The second slider 5081 is provided with a power system. A connecting rod 5082 is mounted on the outside of the second slider 5081 , and a sixth push rod 5083 is mounted on the bottom of the connecting rod 5082 ; The clamping plate 5084 is mounted on the bottom of the sixth push rod 5083. The clamping plate 5084 has a slot formed therein. The slot is made of rubber and the top of the slot gradually narrows from bottom to top. An adjusting column 5085 is installed outside the connecting rod 5082; Contact plate 5087 , the contact plate 5087 is installed on the outside of the adjustment column 5085 , and a contact block 5086 is installed at the bottom of the contact plate 5087 .

[0036] Before installing the tool, the power system in the two slides 504 is activated, and the two slides 504 gradually move closer together, thereby driving the two clamping plates 5084 to gradually move closer and into contact. The two sixth push rods 5083 are activated to their maximum stroke, and the two sixth push rods 5083 drive the two clamping plates 5084 downward until the tool is locked into the slot in the two clamping plates 5084. As the top of the slot gradually narrows from bottom to top, the top of the tool gradually locks into the slot, causing slight deformation inside the slot, fixing the tool in place.

[0037] When the tool needs to be released, the two sixth push rods 5083 are opened to the maximum stroke, and the two sixth push rods 5083 drive the two clamps 5084 to move downward. Then the power system is turned on to control the two sliding frames 504 to move in opposite directions, and the tool gradually falls into the first barrel 3041.

[0038] Before using the device, adjust the sixth push rod 5083 to its first stroke. This will drive the clamping plate 5084 downward until it is flush with the bottom of the outer frame 505. Adjust the stroke of the fifth push rod 507 so that the tool ultimately falls into the cutting position. Adjust the power system in the first slider 506. The first slider 506 moves within 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, which in turn transmits a signal to the power system. The power system controls the upward movement of the fifth push rod 507, causing the tool to retract and self-limit.

[0039] The position of the tool is controlled by the power mechanism 5 and the locking assembly 508. Two movable slides 504 and two clamping plates 5084 with locking slots are provided to clamp and release the tool. The locking assembly 508 cooperates with the material receiving assembly 304 and the material feeding assembly 306 to complete the removal and installation of the tool. When the tool reaches the cutting position, the contact block 5086 is controlled to contact the contact point, transmitting a signal to the power system to control the tool retraction and perform self-limiting of the tool.

[0040] Working principle: Before using the equipment, adjust the power mechanism 5 and the control mechanism 3 and install the tool in the positioning assembly 508.

[0041] Before using the equipment, open the fourth push rod 501 to the first stroke, the fourth push rod 501 drives the movable cylinder 502 to move outward, and the movable cylinder 502 is gradually located directly above the first barrel 3041. Adjust the positioning assembly 508, and the tool can be disassembled and replaced at this time.

[0042] 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. The disposable bag is manually placed on the outside of the annular plate 3045, and the edge of the bag is pressed so that the round edge of the bag is sucked into the suction strip.

[0043] When the tool needs to be released, the two sixth push rods 5083 are opened to the maximum stroke, and the two sixth push rods 5083 drive the two clamps 5084 to move downward. Then the power system is turned on to control the two sliding frames 504 to move in opposite directions, and the tool gradually falls into the first barrel 3041.

[0044] As the positioning assembly 508 releases the cutter, the cutter gradually enters the disposable bag in the first barrel 3041. Then, the second push rod 3044 is opened, and the second push rod 3044 drives the ring, the protrusion 3046, the suction strip and the disposable bag to move upward, and then the disposable bag can be manually taken out.

[0045] Before using the equipment, the second barrel 3061 is at the bottom of the protective plate 309. As the connecting frame 303 drives the second barrel 3061 to move to the bottom of the positioning assembly 508, the third push rod 3063 is opened, and the third push rod 3063 drives the support plate 3064, the third barrel 3065 and the partition 3066 to rise to the highest position. The tool is manually clamped into the two partitions 3066. At this time, the bottom of the tool is in the two partitions 3066. Adjust the third push rod 3063 to the initial state, and the third push rod 3063 drives the support plate 3064, the third barrel 3065 and the partition 3066 back to their original position.

[0046] Before installing the tool, the power system in the two slides 504 is turned on, and the two slides 504 gradually move closer together, thereby driving the two clamping plates 5084 to gradually move closer together and contact each other. The two sixth push rods 5083 are turned on to their maximum stroke, and the two sixth push rods 5083 drive the two clamping plates 5084 to move downward.

[0047] As the positioning assembly 508 moves downward, the third push rod 3063 is opened, and the third push rod 3063 drives the support plate 3064, the third barrel 3065 and the partition 3066 to rise to the highest position. The partition 3066 drives the tool to rise until the tool is stuck in the slot in the two clamps 5084. Since the top of the slot gradually narrows from bottom to top, the top of the tool gradually gets stuck in the slot, and the inside of the slot is slightly deformed, fixing the position of the tool. The sixth push rod 5083 is adjusted to the initial state, and the positioning assembly 508 drives the tool to move upward, and the tool gradually separates from the partition 3066.

[0048] Then adjust the position of the base 1, push the base 1 to the location where the equipment is used, turn on the control mechanism 3, adjust the direction of the power mechanism 5, and turn on the power mechanism 5 to control the position of the tool.

[0049] Before using the device, adjust the sixth push rod 5083 to its first stroke. This will drive the clamping plate 5084 downward until it is flush with the bottom of the outer frame 505. Adjust the stroke of the fifth push rod 507 so that the tool ultimately falls into the cutting position. Adjust the power system in the first slider 506. The first slider 506 moves within 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, which in turn transmits a signal to the power system. The power system controls the upward movement of the fifth push rod 507, causing the tool to retract and self-limit.
