Referring to fig. 2, fig. 2 is a view taken along direction a of fig. 1. The input assembly 110 generally includes a conveyor belt 112, and the sorter assembly 120 is located at the end of the direction of travel of the conveyor belt 112. The conveying belt 112 is used for conveying the surgical instruments, so that the operation of workers is facilitated, and the safety factor is high. And the conveying speed of the conveying belt 112 is controllable, so that the workers can freely adjust the conveying speed according to actual conditions, and the working flexibility is higher.

The sorter assembly 120 generally includes a first sorter bar 122, a second sorter bar 124, and a chassis 126. The bottom tray 126 is located below the first sorting bar 122 and the second sorting bar 124, and the bottom tray 126 provides a moving support plane for the surgical instruments. The first sorting lever 122 and the second sorting lever 124 are respectively located at both sides of the conveying direction of the conveyor belt 112, so that the surgical instruments conveyed by the conveyor belt 112 enter between the first sorting lever 122 and the second sorting lever 124. The end of the first sorting lever 122 close to the conveyor belt 112 and the end of the second sorting lever 124 close to the conveyor belt 112 are both rotatably connected to the chassis 126, so that the first sorting lever 122 and the second sorting lever 124 can rotate by different angles, respectively, to guide different surgical instruments to different orientations. The first and second sorting bars 122, 124 and the chassis 126 cooperatively define a sorting channel 125 such that the surgical instruments conveyed by the conveyor belt 112 can enter the receiving assembly 140 through the sorting channel 125.

In this embodiment, the first sorting rod 122 and the second sorting rod 124 can be both provided with telescopic rods (as shown in fig. 2). One end of the first sorting rod 122 close to the conveyor belt 112 and one end of the second sorting rod 124 close to the conveyor belt 112 are both rotatably connected with the chassis 126, and the other end of the first sorting rod 122 far from the conveyor belt 112 and the other end of the second sorting rod 124 far from the conveyor belt 112 are both slidably connected with one side of the chassis 126 far from the conveyor belt 112. Therefore, when the first sorting rod 122 and the second sorting rod 124 rotate around the end close to the conveyor belt 112, the other end can slide on the chassis 126. Meanwhile, the first sorting lever 122 and the second sorting lever 124 may automatically extend and retract to automatically accommodate the distance variation between the two ends.

Referring to fig. 2 and 3, fig. 3 is a schematic structural diagram of the chassis 126. In this embodiment, a groove 127 is formed on a side of the bottom plate 126 away from the conveyor belt 112, and a sliding block (not shown) matched with the groove 127 is disposed on both an end of the first sorting rod 122 away from the conveyor belt 112 and an end of the second sorting rod 124 away from the conveyor belt 112, and the sliding block and the groove 127 are matched to realize sliding connection.

The shutter 128 can open or close the entrance of the sorting passage 125. If the surgical instrument entering the conveyor belt 112 is not satisfactory or is not recognizable, the shutter 128 can close the entrance of the sorting channel 125, and the surgical instrument is not sorted, but is left to the staff for corresponding processing. Thereby guaranteeing the efficiency and the accuracy of the overall sorting and avoiding the trouble of the follow-up use caused by the sorting error of the surgical instruments. The situation that the surgical instrument cannot meet the requirement comprises the fact that the total identification frequency of the surgical instrument reaches the specified number, namely the use frequency of the surgical instrument reaches the maximum frequency, at the moment, the surgical instrument is required to be scrapped and is not required to enter the step of sorting and storing.

In this embodiment, the baffle 128 is disposed between the first sorting rod 122 and the second sorting rod 124 (as shown in fig. 2), and a telescopic cylinder (not shown) is connected to a side of the baffle 128 away from the conveyor belt 112, and the telescopic cylinder can be mounted on a peripheral bracket (not shown). The distance between the baffle 128 and the conveyor belt 112 is adjusted by the expansion and contraction of the telescopic cylinder, so that the surgical instruments on the conveyor belt 112 are stopped or released, and the inlet of the sorting channel 125 is closed or opened. Of course, in other embodiments, the shutter 128 may control the opening and closing of the inlet of the sorting channel 125 in other manners, such as the shutter 128 may rotate on a plane perpendicular to the conveying direction of the conveyor belt 112.

Further, the sorter assembly 120 may further include a chute 130, and the surgical instruments sorted from the sorting passage 125 are transferred to the receiving assembly 140 using the chute 130.

Referring to fig. 2 and 4, fig. 4 is a schematic structural view of the receiving assembly 140. The receiving assembly 140 includes a supporting frame (not shown) and a plurality of storage cells 142, wherein the storage cells 142 are fixed to the supporting frame, and the supporting frame provides a supporting and mounting platform for the receiving assembly 140. Each storage compartment 142 is for receiving a designated surgical instrument sorted by sorting channel 125. Each surgical instrument has a corresponding storage compartment 142, and each storage compartment 142 can receive a different number of surgical instruments. After the surgical instruments are stored in the storage grid 142, the subsequent treatment of the surgical instruments, such as disinfection, handover and the like, is facilitated. The surgical instruments stored in each storage grid 142 are designated, the number and the types of the surgical instruments are preset, and after the storage grids 142 finish receiving all the designated surgical instruments, a worker can perform subsequent processing on the storage grids 142 and leave the storage grids 142 empty again for receiving another batch of designated surgical instruments.

The receiving assembly 140 may include a plurality of rows and columns of storage cells 142. In this embodiment, the receiving assembly 140 may include five rows and nine columns of storage cells 142 (as shown in fig. 4). The sorter assembly 120 includes a plurality of chutes 130, the number of the chutes 130 is the same as the number of columns of the storage compartments 142, and each of the chutes 130 corresponds to one column of the storage compartments 142. The sorting channels 125 are in communication with designated slides 130 according to the class of surgical instrument.

Referring to fig. 1 and 5, fig. 5 is a schematic structural view of the sorting apparatus 100 after the chute 130 rotates. Further, one end of each slide 130 adjacent to the bottom plate 126 is rotatably connected to the bottom plate 126, so that different surgical instruments in the same slide 130 can enter the corresponding column of designated storage cells 142 (the column of storage cells 142 corresponds to each slide 130). After the sorted surgical instruments enter the slide ways 130 in the corresponding columns, the corresponding slide ways 130 rotate by a specified angle (as shown in fig. 5), so that the surgical instruments enter the storage cells 142 in the specified rows, the surgical instruments enter the specified storage cells 142 in the specified columns in the specified rows, and the surgical instruments are stored.

In this embodiment, any two adjacent slideways 130 are connected to each other, that is, the slideways 130 rotate synchronously, and the setting is simple. Of course, in other embodiments, each chute 130 may be independent of another, that is, each chute 130 may rotate independently, and is not affected by other chutes 130 or affects other chutes 130, and this arrangement can better improve the sorting efficiency.

The rotation of the slide 130 can be driven by a motor (not shown in the figure), which is convenient and fast, and can accurately control the rotation angle.

In this embodiment, the receiving assembly 140 has a predetermined arc structure (as shown in fig. 1). The shape of the storage assembly 140 is matched with the rotation track of the tail end of the slide 130, so that the tail end of the slide 130 can still be directly communicated with the corresponding storage lattice 142 before and after the slide 130 rotates, the surgical instruments in the slide 130 can be stored in the corresponding storage lattice 142, and the storage stability is guaranteed. Of course, in other embodiments, the storage assembly 140 may not be additionally provided, but the slide 130 is provided as a controllable telescopic structure, and the slide 130 is controlled to correspondingly extend and retract while the slide 130 rotates, so that the end of the slide 130 can always be communicated with the corresponding storage compartment 142.

Further, the sorter assembly 120 is disposed in an inclined manner (as shown in fig. 1 and 5), that is, a horizontal plane of a side of the sorter assembly 120 close to the input assembly 110 is higher than a horizontal plane of a side of the sorter assembly 120 close to the receiving assembly 140, so as to ensure that the surgical instruments in the sorter assembly 120 can smoothly slide out of the sorter assembly 120 by gravity, and prevent the surgical instruments from being jammed in the sorter assembly 120.

In other embodiments, the slide 130 may not be provided to rotate, but a moving mechanism may be provided on the storage module 140. For example, a lifting platform is disposed at the bottom of the storage assembly 140, a guide rail is disposed on the upper surface of the lifting platform, the height of the storage assembly 140 is adjusted by the lifting platform, so that the outlet of the sorting channel 125 can be aligned with the storage grid 142 at a designated height (i.e., a designated row) corresponding to the surgical instrument, and then the storage assembly 140 is moved by the guide rail, so that the designated storage grid 142 at a designated column of the designated row is communicated with the outlet of the sorting channel 125, and further the designated surgical instrument is stored.

In this embodiment, each storage cell 142 is provided with a counter (not shown in the figure), and the counter is used for counting the number of the surgical instruments in the corresponding storage cell 142. Because the number of the surgical instruments required to be stored in each storage grid 142 is different, whether the storage grid 142 completes the storage requirement can be judged according to the detection result of the counter, so that the condition of incomplete storage is avoided, and the subsequent processing of the surgical instruments is prevented from being influenced.

The working principle of the sorting device 100 is as follows:

the surgical instruments with the unique bar codes printed thereon are placed on the conveyor belt 112.

The identification component identifies the surgical instrument. If the identification fails or the total number of identifications of the surgical instrument has reached a specified number (e.g., if the total number of identifications has reached 10, indicating that the surgical instrument has been used 10 times, the surgical instrument should not be placed in service again), the flap 128 is not raised, blocking the surgical instrument from entering the sorter assembly 120, and waiting for the surgical instrument to be processed (e.g., recycled) by the worker. And if the identification is successful and the total identification frequency does not meet the requirement, controlling the telescopic air cylinder to stretch and contract, lifting the baffle 128 and designating the corresponding storage grid 142. After the surgical instrument enters the sorting channel 125 through the baffle 128, the telescopic cylinder is again retracted, so that the baffle 128 falls down again, and the sorting channel 125 is closed.

The first sorting lever 122 and the second sorting lever 124 are respectively rotated by a designated angle according to the position of the slide 130 corresponding to the column where the designated storage grid 142 is located, so that the end of the sorting channel 125 communicates with the designated slide 130, and the surgical instrument can enter the designated slide 130 (as shown in fig. 2).

According to the row of the designated storage compartment 142, the slide 130 is rotated by a corresponding angle, so that the end of the slide 130 is communicated with the designated storage compartment 142 (as shown in fig. 1 and 5), thereby allowing the surgical instrument to enter the designated storage compartment 142. At this time, the counter corresponding to the cell 142 counts once.

When the storage compartment 142 has finished storing the specified number and types of surgical instruments, the counter prompts completion, and prompts the staff to perform subsequent operations (e.g., sterilization) on the surgical instruments in the storage compartment 142. After the cell 142 is emptied, the counter starts counting again.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
