The rotating frame 201 is provided with a plurality of fixed cylinders 202. A rotating cylinder 203 is rotatably arranged inside the fixed cylinder 202. A disinfectant is stored at the bottom of the rotating cylinder 203. A clamping member 204 is arranged inside the rotating cylinder 203. The clamping member 204 is used to clamp a single surgical instrument dropped from the conveying mechanism 100. A telescopic mechanism 205 is also arranged inside the rotating cylinder 203. The telescopic mechanism 205 drives the clamping member 204 to slide downward along the inside of the rotating cylinder 203, so that the clamping member 204 clamps a single surgical instrument and immerses it in the disinfectant for disinfection. The rotating frame 201 is provided with a driving device (not shown in the figure). The driving device is used to drive the rotation of the rotating frame 201. The steering conveyor belt 103 includes two conveyor belts arranged at intervals. The speeds of the two conveyor belts are different, so as to realize the steering of the surgical instrument. In this embodiment, a plurality of partitions are spaced apart on the partition conveyor belt 102 along the moving direction of the partition conveyor belt 102. When the surgical instrument is on the partition conveyor belt 102, the length direction thereof is the same as the length direction of the partitions. After being turned by the turning conveyor belt 103, the length direction of the surgical instrument is the same as the moving direction of the turning conveyor belt 103, and the surgical instrument can fall from the gap between the two conveyor belts.

[0023] In this way, by setting up the conveying mechanism 100, multiple surgical instruments with disinfection parts can be separated into individual surgical instruments. The individual surgical instruments fall into the clamping parts 204 of each rotating drum 203, and then the telescopic mechanism 205 in each rotating drum 203 drives the clamping parts 204 to slide downward along the inside of the rotating drum 203, and then the clamping parts 204 clamp the individual surgical instruments and immerse them in the disinfectant for disinfection. In this way, individual surgical instruments can be disinfected, thereby improving the cleaning efficiency and cleaning effect.

[0024] In one embodiment, the clamping member 204 includes two symmetrically arranged arc-shaped clamping blocks 2044, each of which is provided with a plurality of telescopic rods 2041, the telescopic rods 2041 being used to clamp surgical instruments, and the outer peripheral surface of the arc-shaped clamping block 2044 is provided with a telescopic block 2042, the telescopic rod 2041 and the telescopic block 2042 being connected via a hydraulic circuit. Thus, when the telescopic rod 2041 clamps the surgical instrument, the telescopic rod 2041 contracts and the hydraulic oil in the telescopic rod 2041 enters the telescopic block 2042, causing the telescopic block 2042 to extend.

[0025] In one embodiment, a vertical groove 2032 is provided on the rotating cylinder 203, and the telescopic block 2042 can slide up and down along the vertical groove 2032. The inner circumferential surface 2031 of the fixed cylinder 202 is provided with a spiral groove 2022 and an avoidance groove 2021. The avoidance groove 2021 corresponds to the vertical groove 2032, and the spiral groove 2022 is connected to the avoidance groove 2021. The groove depth of the spiral groove 2022 gradually increases from top to bottom. After the telescopic block 2042 is extended, it can pass through the vertical groove 2032 and enter the spiral groove 2022. When the rotating cylinder 203 drives the clamping member 204 to rotate around the fixed cylinder 202, the telescopic block 2042 can rotate along the spiral groove 2022 and thereby drive the clamping member 204 to move upward along the fixed cylinder 202.

[0026] In one embodiment, a slider 2043 is slidably connected between the two arc-shaped clamping blocks 2044, and the diameter of the inner circumference 2031 of the rotating cylinder 203 gradually decreases from top to bottom. The telescopic mechanism 205 drives the slider 2043 to move downward along the inner circumference 2031 of the rotating cylinder 203, so that the two arc-shaped clamping blocks 2044 are close to each other, thereby clamping the surgical instrument. In this embodiment, the telescopic mechanism 205 is a hydraulic rod.

[0027] In one embodiment, the arc-shaped clamping block 2044 is provided with an arc-shaped sliding groove on one side facing the slider 2043, and the arc-shaped clamping block 2044 slides along the slider 2043 through the arc-shaped sliding groove. When both arc-shaped clamping blocks 2044 slide along the slider 2043, the two arc-shaped clamping blocks 2044 approach each other.

[0028] In one embodiment, a vibration motor 208 is provided on the fixed cylinder 202, and the vibration motor 208 can vibrate the rotating cylinder 203. A driving motor 207 is provided at the bottom of the rotating cylinder 203, and the driving motor 207 is used to drive the rotating cylinder 203 to rotate relative to the fixed cylinder 202. The vibration motor 208 can vibrate the disinfectant in the rotating cylinder 203, thereby improving the disinfection effect. In order to ensure the stability of the driving motor 207, a support rod is provided on the rotating frame 201, and an arc groove 2071 is provided on the driving motor 207. The support rod is located in the arc groove 2071 to support the driving motor 207.

[0029] In one embodiment, the bottom of the rotating cylinder 203 is provided with a rotating groove, and the bottom of the fixed cylinder 202 is rotatably arranged in the rotating groove, and the bottom of the fixed cylinder 202 is stopped and matched with the rotating groove in the up and down directions. The bottom of the rotating cylinder 203 is engaged with the bottom of the fixed cylinder 202, so that they can rotate relatively and stop and match up and down.

[0030] In one embodiment, a liquid discharge port is provided at the bottom of the drum 203, and a solenoid valve 206 is provided inside the liquid discharge port, and the solenoid valve 206 is used to control the opening and closing of the liquid discharge port. In this way, after the disinfection is completed, the disinfectant can be discharged from the inside of the drum 203 for subsequent reuse.

[0031] In one embodiment, an absorbent cloth is provided above the inner circumferential surface 2031 of the rotating drum 203, and the absorbent cloth is used to absorb the disinfectant on the surgical instrument. When the clamping member 204 clamps the surgical instrument and moves upward, the absorbent cloth will come into sliding contact with a part of the surgical instrument, thereby absorbing the disinfectant attached to the surgical instrument, thereby improving the cleaning effect of the surgical instrument.

[0032] In one embodiment, the fixed cylinder 202 can rotate up and down relative to the rotating frame 201, and an output conveyor belt 300 is provided below one of the fixed cylinders 202, and the output conveyor belt 300 is used to receive the sterilized surgical instruments. The output conveyor belt 300 transports the sterilized surgical instruments to the high-pressure steam sterilization device for secondary sterilization. The rotating frame 201 is provided with a rotating motor (not shown in the figure), and the rotating motor drives the fixed cylinder 202 to rotate up and down along the rotating frame 201.

[0033] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows: The driving device drives the rotating frame 201 to rotate, thereby driving the multiple fixed cylinders 202 to rotate, and then multiple surgical instruments are placed on the receiving conveyor belt 101. Then, the multiple surgical instruments are separated by the partition conveyor belt 102 and turned by the turning conveyor belt 103. A single surgical instrument can fall into the two arc-shaped clamping blocks 2044 in the rotating cylinder 203. Then, the sliding block 2043 is pulled by the telescopic mechanism 205 to move downward along the inner circumference 2031 of the rotating cylinder 203, so that the two arc-shaped clamping blocks 2044 move downward along the inner circumference 2031 of the rotating cylinder 203, and at the same time, the telescopic block 2042 slides along the vertical groove 2032 of the rotating cylinder 203. The two arc-shaped clamping blocks 2044 approach each other during the downward movement, so that the telescopic rod 2041 in the arc-shaped clamping block 2044 clamps the surgical instrument, and then the telescopic rod 2041 is compressed, and at the same time, the telescopic block 2042 gradually extends, and the telescopic block 2042 can pass through the vertical groove 2032 and enter the avoidance groove 2021 of the fixed cylinder 202. After the telescopic mechanism 205 drives the sliding block 2043 to move to the lowest position, it stops driving the sliding block 2043 to move. At this time, the two arc-shaped clamping blocks 2044 clamp the surgical instruments into the disinfectant at the bottom of the drum 203, so as to immerse and disinfect the surgical instruments. The disinfectant is vibrated by the vibration motor 208, which can improve the disinfection effect.

[0034] After the rotating frame 201 rotates 180°, the driving motor 207 is controlled to drive the rotating drum 203 to rotate relative to the fixed drum 202. The rotation of the rotating drum 203 drives the telescopic block 2042 to enter the spiral groove 2022 from the connecting position between the spiral groove 2022 and the avoidance groove 2021. As the rotating drum 203 rotates, the telescopic block 2042 rises along the spiral groove 2022, and then the two arc-shaped clamping blocks 2044 move upward along the rotating drum 203. At the same time, the two arc-shaped clamping blocks 2044 move away from each other, and the telescopic mechanism 205 extends synchronously. During the rising process, the surgical instruments clamped in the two arc-shaped clamping blocks 2044 will be separated from the disinfectant and contact the absorbent cloth inside the rotating drum 203, thereby wiping the surgical instruments to avoid excessive disinfectant from adhering to the surgical instruments. When the two arc-shaped clamping blocks 2044 move to the highest position, the telescopic block 2042 is squeezed by the spiral groove 2022 and shrinks. When reaching the highest position, the telescopic block 2042 disengages from the spiral groove 2022 and enters the vertical groove 2032, so that the telescopic rod 2041 recovers its initial length. At the same time, the two arc-shaped clamping blocks 2044 move away from each other to release the surgical instruments to the initial clamping state. At this time, the electromagnetic valve 206 is opened to discharge the disinfectant. As the fixed cylinder 202 rotates to the top of the output conveyor belt 300, the rotating motor is controlled to rotate the fixed cylinder 202 up and down 180 degrees, and the surgical instruments are poured onto the output conveyor belt 300, and moved to the high-pressure steam sterilization device for secondary disinfection.

[0035] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
