Description

Technical Field

[0001] The invention relates to an acceptance device, in particular to an acceptance device used for orthopedic implants. Background Art

[0002] Implants (implantable devices) refer to implantable items that are placed in a body cavity created by surgical operations or physiologically existing, and remain in the body for 30 days or more. In recent years, with the continuous improvement of surgical skills and the large-scale development of minimally invasive surgeries, the use of implantable devices has increased, especially orthopedic implantable devices. The UDI barcode for orthopedic implants is the only basis for the factory qualification and identity of the implants, and is also an effective proof of quality traceability, with legal effect. The so-called UDI code includes several coding rules on the market. Take the GS1 rule coding widely used in the market as an example: a barcode in the form of (01) xxxxxx (17) xxxxxxx (10) xxxxxx (21) xxxxxxx, (01) followed by (17) is a fixed main barcode, (17) followed by (10) is generally the expiration date or production date of the product, (10) followed by (21) is generally the production batch number of the product, and (21) is the unique identifier of the product. At present, most hospitals have implemented information-based quality traceability for the cleaning, disinfection, sterilization, packaging, and use of external device implants, but few hospitals have standardized management of the inspection barcodes of orthopedic implants. At present, many domestic hospitals have implemented information-based quality traceability for the cleaning, disinfection, sterilization, packaging, and use of external device implants, but few hospitals have truly standardized management of the inspection UDI barcodes of orthopedic implants. Take implantable orthopedic screws as an example. Orthopedic screws are a type of implantable orthopedic medical consumables. There are many types of orthopedic screws, such as metal locking bone plate screws, cortical bone screws, compression screws, etc. In addition, since the size of the screws is often small, the barcode is mainly engraved with letters and digital tracking codes (i.e., production batch numbers or unique identification codes), and is engraved on the outer peripheral wall of the tail of the screw or the nail body. For example, a Chinese invention patent application "Implant Screws" with application number CN200480042917.2 (publication number CN1946349A) is used as an implant screw for correcting and stabilizing the spine. It has an end portion arranged on the axial end of the screw, and a clamp portion is connected thereto. It has a clamp receiving body for fixing a connecting rod on the end portion, and a threaded hole for accommodating a thread assigned to the end portion is formed in the clamp portion. The inspection barcode of the implant screw is engraved on the end face of the tail of the implant screw, while another type of screw, such as the Chinese utility model "An anchor reinforced bone screw" with patent number 201721649850.X (authorization announcement number CN208640858U), has a screw body, and the screw body includes a screw cap, a screw body and a screw tip. The screw body and the screw tip are provided with threads, and the screw cap is provided with a structure that facilitates the tool to screw the screw. The inspection bar of this type of screw is engraved on the outer peripheral wall of the screw cap (i.e., the tail of the screw). Since the engraved text is small, it is very difficult to read the tracking code by human eyes, and often requires the use of tools such as a magnifying glass.

[0003] An orthopedic operation, such as a trauma operation, requires hundreds of screws to be prepared in advance, and a hospital performs several or even dozens of orthopedic operations every day, requiring thousands of screws to be inspected. The inspection of such a large number of screws is very mechanical and boring, and consumes a huge amount of human resources. It is estimated that if a comprehensive tertiary hospital with a medium track model needs to inspect all orthopedic screws, it will arrange more than 4 inspectors for orthopedic implants, and the quality of the inspection cannot be guaranteed. Some orthopedic specialty hospitals have a larger number of operations and need to stock more screws. Considering these practical difficulties, most hospitals in China currently adopt the method of random inspection. After the operation is completed, medical staff need to attach the barcode corresponding to the screw implanted in the patient's body to the implantation tracking sheet and save it with the medical record. Since it is impossible to read the code of the screw before implanting it in the operating room, it is difficult to accurately match the attached barcode with the implanted screw one by one, and it is impossible to trace back and track it. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an acceptance device for orthopedic implants, which is convenient for effectively tracing back and forward the orthopedic implants, in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: the acceptance device for orthopedic implants is characterized by: comprising

[0006] Base;

[0007] A limiting seat, arranged above the base and used for limiting the position of the orthopedic implant;

[0008] A camera mechanism, disposed on the base, for photographing a barcode corresponding to the orthopedic implant;

[0009] A first driving mechanism, used for driving the relative movement between the limiting seat and the camera mechanism; and

[0010] A microcontroller is arranged on one side of the base, and the microcontroller is communicatively connected with the camera mechanism;

[0011] The barcode acceptance process of orthopedic implants using the device is as follows: reading the barcode information transmitted to the database through the network; reading the tracking code of the implant; comparing the database barcode and the tracking code; outputting the location of the first orthopedic implant and / or the second orthopedic implant in question or passing the acceptance;

[0012] When the orthopedic implant is used up, the barcode of the orthopedic implant should be affixed to the patient's orthopedic implant tracking sheet. The specific process of affixing the code is as follows: read the original barcode information in the database; use this device to read the tracking code of the remaining implants; output the difference, which is the barcode used; affix the code; and return the remaining implants to the warehouse.

[0013] The first driving mechanism is used to drive the relative movement between the limit seat and the camera mechanism in three ways, wherein the first way is: the first driving mechanism drives the limit seat to rotate circumferentially relative to the camera mechanism, and the camera mechanism is located above the limit seat, wherein:

[0014] The base has a concave cavity with an opening facing upward, and a vertical support rod is arranged at the center of the concave cavity;

[0015] Also included are:

[0016] A connector, which is disposed on the base and includes an annular plate body, the inner edge of the annular plate body is surrounded by a central opening for the support rod to pass through, and the outer peripheral edge of the annular plate body extends in a horizontal direction and can cover the concave cavity;

[0017] The limit seats are provided with at least two and are arranged along the outer periphery of the annular plate body;

[0018] The first driving mechanism is disposed in the concave cavity, and the first driving mechanism is located at the periphery of the support rod to drive the connecting body together with the limiting seat to rotate relative to the base in the circumferential direction;

[0019] A light-shielding cylinder, the opening of which faces downward so as to cover the limiting seat; and

[0020] The camera mechanism includes a first camera unit, which is arranged at the end of the support rod or the inner wall of the light-shielding tube. When the connector and the limit seat rotate circumferentially relative to the base, the barcode corresponding to each first orthopedic implant can be photographed.

[0021] By providing a connector that can be connected to the limit seat on the base, and using the first driving mechanism to drive the connector to drive the limit seat to rotate in the circumferential direction, the first camera unit can capture the barcode corresponding to each first orthopedic implant. At the same time, the opening of the light-shielding tube is facing downward to cover the limit seat and the first camera unit, which can reduce stray light interference and enable more accurate focusing and reading of barcodes. The first camera unit is composed of four to five macro cameras, which are used to capture the barcode engraved on the tail end face of a single implant. A ring light source is provided on the outer circle of the camera module to provide lighting. When shooting, the central camera is exposed once first. When the picture taken by the central camera can be recognized, the surrounding cameras will no longer shoot; otherwise, the images obtained after exposure by the surrounding cameras will be spliced ​​and processed for recognition.

[0022] Furthermore, the first camera part is arranged at the end of the support rod, and correspondingly, each limit seat includes at least two first limit sub-seats arranged side by side along the circumferential direction and at least two second limit sub-seats arranged radially inward and outward, and the first limit sub-seat and the second limit sub-seat are both used to limit the head of the first orthopedic implant and can expose the barcode corresponding to the tail end face of each first orthopedic implant.

[0023] In order to facilitate the installation or disassembly of the limit seat, preferably, each limit seat can slide radially inward and outward relative to the connecting body, the connecting body also includes a limit member, and when each limit seat is connected to the connecting body, each limit seat is maintained in a locked state.

[0024] The first driving mechanism is used to drive the relative movement between the limit seat and the camera mechanism in three ways, among which the second way is: the first driving mechanism drives the limit seat to rotate circumferentially relative to the camera mechanism, the camera mechanism is located relatively above the periphery of the limit seat, and the camera mechanism includes a first camera portion arranged on the inner circumferential wall of the light-shielding tube. Correspondingly, each limit seat includes a seat body that can slide radially inward and outward relative to the connecting body, the seat body includes a vertical wall arranged parallel to the support rod and a transverse wall arranged perpendicular to the support rod, and at least one row of limit seats arranged in parallel along the circumferential direction on the vertical wall, each row of limit seats is composed of at least two limit sub-seats arranged at intervals up and down, the limit sub-seat includes an upper limit sub-block and a lower limit sub-block, the upper limit sub-block and the lower limit sub-block together form an opening whose longitudinal height can be adjusted to accommodate the first orthopedic implant, and the limit seat row is also provided with a first elastic member to make the lower limit sub-block always have a tendency to reset in the direction of reducing the opening.

[0025] In order to conveniently take out the implant after acceptance, preferably, it also includes an actuating member capable of switching the first orthopedic implant from a clamped state between the upper limit block and the lower limit block to a freely released state.

[0026] Furthermore, the upper limit block extends to the vertical wall of the base and is connected thereto, and the actuator includes an inverted U-shaped bracket that can drive the lower limit block to slide relative to the upper limit block, and the top of the inverted U-shaped bracket is provided with a pressing portion for driving the bracket to slide relative to the upper limit block, and the inverted U-shaped bracket is provided with a partition plate that separates adjacent limit sub-seats under the lower limit block, and the center of the partition plate is provided with a first connecting rod that can slide along with the lower limit block, the first elastic member is a first compression spring, the first compression spring is sleeved outside the first connecting rod, and the upper end of the first compression spring is connected to the bottom of the lower limit block, and the lower end of the first compression spring is connected to the partition plate, and a through hole is opened on the partition plate, the head of the first connecting rod is connected in the through hole, and the tail of the first connecting rod is stuck outside the through hole, so as to achieve that the size of the opening can be changed when the inverted U-shaped bracket drives the lower limit block to slide. When the bracket is stationary relative to the upper limit blocks, the implant is inserted into the openings formed between the upper limit blocks and the lower limit blocks, and the implant can compress the lower limit block to connect to the first connecting rod and move downward relative to the partition plate. At this time, the first compression spring is in an energy storage state; and under the action of external force, the inverted U-shaped bracket is driven to move downward to the partition plate, which can pull the first connecting rod and the lower limit block downward to enlarge the opening between the upper limit blocks, and the implant can fall out of the opening.

[0027] Furthermore, at least one second connecting rod is connected to the bottom of the partition plate corresponding to the lower limit block located at the bottom, and the second connecting rod can pass through the fixed plate located at the bottom. The fixed plate outer sleeve is provided with a second compression spring, and the second compression spring makes the fixed plate and the second connecting rod always have a tendency to reset upward, wherein the upper end of the second compression spring is connected to the bottom of the partition plate, and the lower end of the second compression spring is connected to the fixed plate. The length and working stroke of the second compression spring are greater than the first compression spring, so that when an external force is applied to the pressing part, each of the upper limit blocks and the lower limit blocks can be switched to a free release state. Since the length of the second connecting rod and the second compression spring is greater than that of the first connecting rod and the first compression spring, the force when the external force is applied to the pressing part must be sufficient to make the second connecting rod move downward and press the second compression spring downward until each partition plate moves downward and the tail of the first connecting rod is against the peripheral part of the through hole, so that the lower limit block connected thereto can be pulled to move downward.

[0028] In addition to inspecting and accepting orthopedic implants with barcodes on the tail end faces, orthopedic implants with barcodes corresponding to the outer peripheral walls of the tails can also be inspected and accepted. Preferably, the inner peripheral walls of each of the limiting seats extend toward the central opening to form an extension portion, and at least two connecting seats are circumferentially arranged on the extension portion, and each connecting seat has a connecting column for limiting the tail of the second orthopedic implant and exposing the barcodes corresponding to the tail side peripheral walls of each second orthopedic implant or the side walls of the second orthopedic implant, and the rod body of the support rod is provided with a second camera portion that can capture the barcodes corresponding to each second orthopedic implant.

[0029] In order to prevent the barcodes corresponding to the outer peripheral wall of the tail of the second orthopedic implant from being inserted when the second orthopedic implant is inserted, it is necessary to align the barcodes corresponding to the outer peripheral wall of the tail of the second orthopedic implant with the second camera unit one by one. This puts high demands on the insertion accuracy of the second orthopedic implant for the acceptance personnel, and also increases the workload of the acceptance personnel. Preferably, the periphery of the support rod is connected with a support plate located under the extension portion, and the upper surface of the support plate supports a second driving mechanism that can drive each connecting seat to rotate circumferentially relative to the extension portion. Through the second driving mechanism, each connecting seat is rotated circumferentially relative to the extension portion. The acceptance personnel only need to insert the second orthopedic implant into the connecting seat with the nail tail downward, which can effectively reduce the insertion accuracy of the second orthopedic implant and reduce the workload of the acceptance personnel. Among them, the second orthopedic implant can be selected as the anchor plate reinforced bone screw with patent number 201721649850.X. The second camera unit that can capture the barcodes corresponding to each second orthopedic implant can also be directly set on the support plate.

[0030] In order to realize the second driving mechanism to make each connecting seat rotate in the circumferential direction relative to the extension part, the preferred method is: the second driving mechanism includes a second motor and a second transmission mechanism connected to the power output end of the second motor, and the second transmission mechanism is used to drive the connecting seat to rotate in the circumferential direction relative to the extension part.

[0031] In order to realize that the connecting seat has the function of being able to allow the second orthopedic implant to be inserted and being able to rotate in the circumferential direction relative to the extension portion, preferably, the connecting seat also includes a connecting head end exposed under the extension and a connecting tail end extending from under the extension portion, and the second transmission mechanism includes a driving wheel connected to the power output end of the second motor, a driven wheel and a transmission belt respectively connected between the driving wheel and the driven wheel, and the connecting tail end of the connecting seat realizes the circumferential rotation of the connecting head end relative to the extension portion through sliding friction with the driven wheel.

[0032] Furthermore, the lower surface of the support plate is also provided with a third driving mechanism capable of driving the driven wheel to deflect relative to the connecting head end. The third driving device can realize that the connecting seat can only rotate in the circumferential direction with the limiting seat relative to the base, and does not rotate autonomously in the circumferential direction relative to the extension part.

[0033] Furthermore, the third driving mechanism includes an electromagnet arranged on the lower surface of the support plate, a vertical connecting rod integrally connected to the retraction rod of the electromagnet, a transverse transmission rod hinged on the lower surface of the support plate through a pin shaft, a vertical connecting rod arranged at the end of the transverse transmission rod, and a connecting part arranged at the end of the vertical connecting rod and used to support the driven wheel, wherein a mounting hole is opened at the end of the transverse transmission rod for the vertical connecting rod to pass through, thereby achieving: when the retraction rod of the electromagnet is extended, the transverse transmission rod and the vertical connecting rod are close to the electromagnet and thus drive the driven wheel to deflect to the connecting head end, and when the retraction rod of the electromagnet is retracted, the transverse transmission rod and the vertical connecting rod are away from the electromagnet and thus drive the driven wheel to slide and rub against the connecting head end.

[0034] In order to realize the relative rotation between the limit seat and the camera mechanism, from the perspective of simple structure, preferably, the first driving mechanism includes a first motor, a first transmission mechanism connected to the power output end of the first motor, the first transmission mechanism is used to drive the connecting body together with the limit seat to rotate relative to the base in the circumferential direction, the first transmission mechanism includes a first gear driven to rotate by the first motor, and a cylindrical drive ring located on the periphery of the support rod, the peripheral wall of the drive ring is formed with a gear part meshing with the first gear, the first camera part has two, which can be accurately extended and retracted inward and outward in the radial direction relative to the limit seat; and the light-shielding tube can be lifted up and down relative to the end of the support rod, thereby realizing that the light-shielding tube can be lifted up and down relative to the end of the support rod, which can conveniently reduce stray light interference. The first camera part can be driven by an electric cylinder to accurately extend and retract inward and outward in the radial direction relative to the limit seat, and the light-shielding tube can be lifted up and down relative to the end of the support rod by a screw rod or an electric cylinder.

[0035] In order to speed up the first camera unit to shoot the barcodes of each first orthopedic implant of the limiting seat, and at the same time, to reduce the interference of stray light, preferably, in order to realize the acceptance of the next batch of first orthopedic implants quickly after the acceptance of one batch of first orthopedic implants, preferably, each of the limiting seats can slide radially inward and outward relative to the connector, and the connector also includes a limiting member, and when each of the limiting seats is connected to the connector, each of the limiting seats is maintained in a locked state. By the limiting seat being able to slide radially inward and outward relative to the connector, the replacement of different batches of first orthopedic implants can be achieved. When the next batch of first orthopedic implants is limited on the connector, it is only necessary to slide the limiting seat radially inward relative to the connector and lock it through the limiting member. The locking of the limiting member can be achieved through an elastic member.

[0036] The first driving mechanism is used to drive the relative movement between the limit seat and the camera mechanism in three ways, among which the third way is: the first driving mechanism drives the limit seat to move in a horizontal direction relative to the camera mechanism, the limit seat includes a base, an implant plate arranged above the base, and a support rod connecting the base and the implant plate, the first driving mechanism drives the limit seat to move in a horizontal direction relative to the camera mechanism through a third transmission mechanism, the third transmission mechanism includes a frame, two rollers arranged at the head and tail ends of the frame, and a conveyor belt wrapped around the two rollers for transporting the limit seat, the first driving mechanism is provided with a third motor and a fourth motor on the outer side of the frame for driving the two rollers to rotate, the power output ends of the third motor and the fourth motor are respectively connected to the corresponding rollers.

[0037] Compared with the prior art, the advantage of the present invention is that the barcode information corresponding to the orthopedic implant is transmitted to the microcontroller by means of video recording, thereby automatically realizing the barcode management of the orthopedic implant inspection, strictly controlling the quality from the source, realizing quality traceability, effectively safeguarding the rights and interests of patients, and reducing safety hazards. At the same time, during the video recording process, the relative rotation between the limit seat and the camera mechanism can realize the accurate reading of the barcode and the position of each orthopedic implant corresponding to the limit seat, which is conducive to finding the orthopedic implant whose barcode information does not correspond, effectively tracing forward and backward, improving the accuracy of acceptance and coding, and ensuring the traceability of orthopedic implants. In addition, the present invention has a small size and low cost, and is suitable for most occasions. BRIEF DESCRIPTION OF THE DRAWINGS

The acceptance device for orthopedic implants in this embodiment includes a base 1, a limiting seat 2 arranged on the base 1 for limiting the orthopedic implant, a camera mechanism arranged on the base 1 for photographing the barcode corresponding to the orthopedic implant, and a first driving mechanism 4 arranged below the base 1 for driving the relative rotation between the limiting seat 2 and the camera mechanism, and a microcontroller arranged on one side of the base 1, the microcontroller is connected to the camera mechanism for communication, and the barcode information corresponding to the orthopedic implant is transmitted to the microcontroller by means of video, thereby automatically realizing the barcode management of orthopedic implant inspection, which can strictly control the quality from the source, realize quality traceability, effectively protect the rights and interests of patients, and reduce safety hazards.

[0061] Specifically, the orthopedic implant of the present invention is mainly aimed at spinal surgery and trauma surgery screws with tracking letters and digital codes engraved on the end face of the tail 110b, the side wall 120b of the tail or the nail body 120c. The acceptance process is first carried out by taking the first orthopedic implant 110 with a tracking barcode engraved on the end face of the tail 110b as an example: wherein the base 1 of the acceptance device has a concave cavity 11 with an opening 215 facing upward, and a vertical support rod 12 is arranged at the central position of the concave cavity 11; it also includes a connector 5 arranged on the base 1, and the connector 5 includes The annular plate body 51 is enclosed, and the inner side edge of the annular plate body 51 is surrounded by a central opening 511 for the support rod 12 to pass through, and the outer peripheral edge of the annular plate body 51 extends in the horizontal direction and can cover the concave cavity 11; the limiting seat 2 has at least two and is arranged along the outer peripheral edge of the annular plate body 51, each limiting seat 2 includes at least two first limiting sub-seats 21 arranged side by side along the circumferential direction and at least two second limiting sub-seats 22 arranged radially inside and outside, and the first limiting sub-seat 21 and the second limiting sub-seat 22 are both for the first orthopedic implant 110 The head 120a is limited and can expose the bar code corresponding to the end face of the tail 110b of each first orthopedic implant 110; in this embodiment, three limiting seats 2 are taken as an example, and each limiting seat 2 has 9 first limiting sub-seats 21 in each row of the first limiting sub-seats 21 along the circumferential direction and 3 rows of second limiting sub-seats 22 arranged radially inside and outside, that is, 9*3=27 limiting sub-seats, wherein the first limiting sub-seat 21 and the second limiting sub-seat 22 are both in the form of a countersunk hole with an open upper end, and a relatively arranged L-shaped first elastic member is integrally connected at the upper open mouth of the countersunk hole. The first elastic sheet and the second elastic sheet each include a vertical portion connected to the wall of the countersunk hole and a transverse portion arranged oppositely, the end of each transverse portion extends downward from top to bottom with an elastic end toward the vertical portion, a gap is formed between the elastic end of the first elastic sheet and the transverse portion of the second elastic sheet for the head 110a of the first orthopedic implant 110 to be inserted, and the elastic end of the first elastic sheet and the elastic end of the second elastic sheet always have a tendency to reduce the gap between the gaps, thereby being able to clamp the head 110a of the first orthopedic implant 110. In addition, in order to reduce the volume of the entire acceptance device, the first driving mechanism 4 is arranged in the concave cavity 11, and the first driving mechanism 4 is located on the periphery of the support rod 12 to drive the connecting body 5 together with the limiting seat 2 to rotate circumferentially relative to the base 1. A first camera unit 7 is arranged at the end of the support rod 12. When the connecting body 5 together with the limiting seat 2 rotate circumferentially relative to the base 1, the barcode corresponding to each first orthopedic implant 110 can be photographed; finally, a light-shielding tube 6 is also included, and the opening 215 of the light-shielding tube 6 faces downward to cover the limiting seat 2 and the first camera unit 7. The setting of the light-shielding tube 6 enables the first camera unit 7 to better photograph the barcode corresponding to each first orthopedic implant 110.To this end, a connector 5 that can be connected to the limit seat 2 is provided on the base 1, and the first driving mechanism 4 is used to drive the connector 5 to drive the limit seat 2 to rotate in the circumferential direction, so that the first camera unit 7 can capture the barcodes corresponding to each first orthopedic implant 110. In order to achieve relative rotation between the limit seat 2 and the camera mechanism, from the perspective of simple structure, preferably, the first driving mechanism 4 includes a first motor 41, and a first transmission mechanism 42 connected to the power output end of the first motor 41. The first transmission mechanism 42 is used to drive the connector 5 together with the limit seat 2 to rotate relative to the base 1 in the circumferential direction. The first transmission mechanism 42 includes a gear driven to rotate by the first motor 41, and a cylindrical drive ring 422 located on the periphery of the support rod 12, and the peripheral wall of the drive ring 422 is formed with a gear portion 4221 meshing with the gear. At the same time, in order to reduce the friction caused by the circumferential rotation of the drive ring 422 relative to the concave cavity 11 of the base 1, the bottom of the drive ring 422 is connected to a base bearing 423. At the same time, the opening 215 of the light-shielding tube 6 is facing downward to cover the limiting seat 2 and the first camera unit 7, wherein the first camera unit 7 is composed of four to five macro cameras for photographing the barcode engraved on the end face of the tail of a single implant, and the optical center of the central camera and the peripheral cameras is always aligned with the tail of the implant on the limiting seat. A ring light source is set on the outer circle of the camera module to provide lighting. When shooting, the central camera is exposed once first. When the picture taken by the central camera can be recognized, the surrounding cameras will no longer shoot; otherwise, the surrounding cameras will splice and process the obtained images after exposure for recognition, and in order to speed up the first camera unit 7 to shoot the barcodes of each first orthopedic implant 110 of the limit seat 2, and at the same time, to conveniently reduce stray light interference, preferably, the first camera unit 7 has two, which can be driven by the first electric cylinder 71 and the second electric cylinder 123 respectively, and can be extended and retracted inward and outward in the radial direction relative to the limit seat 2; and the light-shielding tube 6 is driven by the screw rod 122, and can be lifted up and down relative to the end of the support rod 12, thereby realizing that the light-shielding tube 6 can be lifted up and down relative to the end of the support rod 12, which can conveniently reduce stray light interference. In order to realize the acceptance of the next batch quickly after the acceptance of the first orthopedic implants 110 of one batch, the acceptance device preferably has each limit seat 2 that can slide radially inward and outward relative to the connector 5, and the connector 5 also includes a limit member, and when each limit seat 2 is connected to the connector 5, each limit seat 2 is maintained in a locked state.The limiting seat 2 can slide radially inward and outward relative to the connecting body 5 in a manner such as a slide groove manner, so that different batches of implants can be easily replaced. When the first orthopedic implant 110 of the next batch is limited on the connecting body 5, it is only necessary to slide the limiting seat 2 radially inward relative to the connecting body 5 and lock it through a limiting member, wherein the locking of the limiting member can be achieved in conjunction with an elastic component, such as a compression spring, one end of which is connected to a recess on the outer peripheral edge of the connecting body 5, and the other end of the compression spring is connected to a limiting member such as a limiting block. When the limiting seat 2 slides radially inward relative to the connecting body 5, the compression spring and the limiting block are pressed into the recess. When the limiting seat 2 slides into place, the limiting sub-block 214 can be blocked outside the limiting seat 2 under the action of the elastic restoring force of the compression spring to prevent the limiting seat 2 from falling when it rotates circumferentially relative to the base 1.

[0062] In addition, the acceptance device of this embodiment can not only accept the first orthopedic implant 110 with a barcode on the end surface of the tail 110b, but also accept the second orthopedic implant 120 with a barcode corresponding to the tail side wall 120b or the nail body 120c, wherein the shape of the second orthopedic implant 120 can refer to the anchor plate reinforced bone screw with patent number 201721649850.X, or Figure 20-BThe barcode of this type of bone screw is engraved on the tail side wall 120b. Therefore, the acceptance method of the first orthopedic implant 110 cannot be used. Instead, the acceptance method of placing the nail body 120c upward so that the barcode of the nail body 120c or the tail side wall 120b is exposed to the outside is adopted. In this embodiment, the inner wall of each limiting seat 2 extends toward the central opening 511 to form an extension portion 20, and at least two connecting seats 201 are circumferentially arranged on the extension portion 20. Each connecting seat 201 has an elastic connecting column 2014 for limiting the U-shaped tail side wall 120b of the second orthopedic implant and exposing the barcode corresponding to the tail side wall 120b of each second orthopedic implant. The rod body or the support plate 121 of the support rod 12 is provided with a second camera 9 that can capture the barcode corresponding to each second orthopedic implant. In order to prevent the second orthopedic implant from being inserted, the barcodes corresponding to the side circumferential wall 120b of the tail of the second orthopedic implant or the nail body 120c must be aligned one by one with the second camera unit 9. This puts high demands on the insertion accuracy of the second orthopedic implant for the acceptance personnel, and also increases the workload of the acceptance personnel. For this reason, a bearing 2013 is arranged outside the connecting seat 201 so that the connecting seat 201 can rotate circumferentially. The periphery of the support rod 12 is connected to a supporting plate 121 located under the extension portion 20. The upper surface of the supporting plate 121 supports a second driving mechanism 30 that can drive each connecting seat 201 to rotate circumferentially relative to the extension portion 20. Through the second driving mechanism 30, each connecting seat 201 is rotated relative to the extension portion 20 The second orthopedic implant can be rotated in the circumferential direction, and the acceptance personnel only need to insert the second orthopedic implant on the connecting seat 201. Through the circumferential rotation of the second orthopedic implant, the second camera unit 9 can capture the side wall or the nail body at different angles, so as to find the barcode for analysis and reading, thereby effectively reducing the accuracy of the acceptance personnel in inserting the second orthopedic implant, thereby greatly reducing the workload. In addition, the second camera unit is composed of three macro cameras with different focal lengths, which are used to capture the barcode of the nail body of the second orthopedic implant and for appearance acceptance. A circle of light sources are set around for lighting. When shooting, two macro cameras capture the barcodes of different types of nail bodies, and a camera with a wider focal length captures the appearance of the second orthopedic implant, including shape, size, color, etc. In order to realize the second driving mechanism 30 to make each connecting seat 201 rotate in the circumferential direction relative to the extension part 20, the preferred method is: the second driving mechanism 30 includes a second motor 301, and a second transmission mechanism 302 connected to the power output end of the second motor 301, and the second transmission mechanism 302 is used to drive the connecting seat 201 to rotate in the circumferential direction relative to the extension part 20.In order to realize that the connecting seat 201 has the function of being able to accommodate the second orthopedic implant and being able to rotate circumferentially relative to the extension portion 20, the connecting seat 201 also includes a connecting head end 2011 exposed from below the extension portion 20 and a connecting tail end 2012 extending from below the extension portion 20. The second transmission mechanism 302 includes a driving wheel 3021 connected to the power output end of the second motor 301, a driven wheel 3022, and a transmission belt 3023 respectively connected between the driving wheel 3021 and the driven wheel 3022. The connecting tail end 2012 of the connecting seat 201 realizes the circumferential rotation of the connecting head end 2011 relative to the extension portion 20 through sliding friction with the driven wheel 3022. Furthermore, the lower surface of the support plate 121 is also provided with a third driving mechanism 40 that can drive the driven wheel 3022 to deflect relative to the connecting head end 2011. The third driving mechanism 40 can realize that the connecting seat 201 can only rotate in the circumferential direction with the limiting seat 2, and does not rotate in the circumferential direction relative to the extension portion 20 autonomously. Specifically, the third driving mechanism 40 includes an electromagnet 401 arranged on the lower surface of the support plate 121, a vertical connecting rod 402 integrally connected to the retracting rod of the electromagnet 401, a transverse transmission rod 403 hinged on the lower surface of the support plate 121 through a pin shaft, and a The vertical connecting rod 404 at the end and the connecting part 405 arranged at the end of the vertical connecting rod 404 and used to support the driven wheel 3022, wherein the end of the transverse transmission rod 403 is provided with a mounting hole 4031 for the vertical connecting rod 402 to pass through, thereby achieving: when the contraction rod of the electromagnet 401 is extended, the transverse transmission rod 403 and the vertical connecting rod 404 are close to the electromagnet 401 and thus drive the driven wheel 3022 to deflect to the connecting head end 2011; when the contraction rod of the electromagnet 401 is retracted, the transverse transmission rod 403 and the vertical connecting rod 404 are away from the electromagnet 401 and thus drive the driven wheel 3022 to slide and rub against the connecting head end 2011.

[0063] The specific code reading process is as follows:

[0064] 1) The acceptance personnel insert the first orthopedic implant 110 and / or the second orthopedic implant 120 into the limiting seat in order according to the size specifications, and install the limiting seat into the device;

[0065] 2) The device pre-reads the brand and specification data of the first orthopedic implant 110 and / or the second orthopedic implant 120 (which can be input through the network or the user interface);

[0066] 3) The first driving mechanism 4 drives the chassis back to the initial position to prepare for code reading;

[0067] 4) The macro camera unit is started, the light source is illuminated, and then each camera starts to focus. If necessary, the camera takes multiple exposures;

[0068] 5) After the first camera unit 7 takes a photo, it performs noise reduction, edge processing, enhanced sharpening, grayscale processing, etc. on the image to make the tracking barcode number clear and easy to read. The image can be straightened to make arc-shaped characters, and the barcode number in the image can be read by general character recognition methods; or the recognition method of convolutional neural network can be used to read directly; if the central camera cannot recognize, the surrounding cameras take images at various angles, and read the barcode after splicing;

[0069] 6) If the tracking code number is not clearly read, the camera unit will refocus and repeat steps 5 to 8. After a certain number of attempts, an error will be automatically reported. At the end, the positions of the nails will be listed for easy comparison by the inspection personnel;

[0070] 7) Outputting the serial number of the unqualified first orthopedic implant 110 and / or the second orthopedic implant 120, which is confirmed by the acceptance personnel;

[0071] 8) After all the first orthopedic implants 110 and / or the second orthopedic implants 120 have been inspected and accepted, the inspector confirms on the user interface, then takes out the stopper and pulls out the implant.

[0072] The process of accepting the first orthopedic implant 110 and / or the second orthopedic implant 120 is: read the barcode information transmitted to the database through the network - read the tracking code of the implant - compare the database barcode and the tracking code - output the position of the first orthopedic implant 110 and / or the second orthopedic implant 120 or pass the acceptance - end, the flowchart can refer to Fig.19 shown.

[0073] In this way, this acceptance device can compare the information of orthopedic implants imported into the database in various ways, such as name, quantity, specification model, serial number and batch number, with the barcode content read during inspection to check their consistency, so as to check whether the implants and barcodes match one by one. If they do not match, the device will output the wrong barcode and the wrong implant position, which will be left for the acceptance personnel to check and solve. After verification, the problematic orthopedic implants will be notified to the equipment manufacturer for timely processing or removal; implants with no problems will be placed together with the barcode book on a special storage rack in the clean area for storage and handover. When the orthopedic implant is used up, the barcode of the orthopedic implant must be affixed to the patient's orthopedic implant tracking sheet. The specific coding process is: read the original barcode information in the database - use this device to read the tracking code of the remaining implants - output the difference - the difference is the used barcode - affix the code - the remaining implants are returned to the warehouse - end, please refer to the following Fig.18 shown. Example 2

[0074] like Figures 8 to 11As shown, the second mode in which the first driving mechanism 4 of the present embodiment is used to drive the relative movement between the limit seat 2 and the camera mechanism is as follows: the first driving mechanism 4 drives the limit seat 2 to rotate circumferentially relative to the camera mechanism, and the camera mechanism is located relatively above the periphery of the limit seat 2, wherein the first camera portion 7 is arranged on the inner circumferential wall of the light-shielding tube 6, and correspondingly, each limit seat 2 includes a seat body 210 that can slide radially inward and outward relative to the connecting body 5, and the seat body 210 includes a vertical wall 211 arranged parallel to the support rod 12 and a vertical wall 211 arranged perpendicular to the support rod 12 The horizontal wall 212 and at least one row of limit seats arranged in parallel along the circumferential direction on the vertical wall 211, each row of limit seats is composed of at least two limit sub-seats arranged at intervals from top to bottom, and the limit sub-seats include an upper limit sub-block 213 and a lower limit sub-block 214, which together form an opening 215 with a longitudinal height that can be adjusted to accommodate the first orthopedic implant 110, and a first elastic member is also provided on the limit seat column to make the lower limit sub-block 214 always have a tendency to reset in the direction of reducing the opening 215. In order to facilitate the first orthopedic implant 110 after acceptance, an actuator is also included that can switch the first orthopedic implant 110 from a clamped state between the upper limit sub-block 213 and the lower limit sub-block 214 to a free release state. The upper limit block 213 extends to the vertical wall 211 of the base 1 and is connected thereto, and the actuator includes an inverted U-shaped bracket 8 that can drive the lower limit block 214 to slide relative to the upper limit block 213, and the top of the inverted U-shaped bracket 8 is provided with a pressing portion 81 for driving the bracket to slide relative to the upper limit block 213, and the inverted U-shaped bracket 8 is provided with a partition plate 82 for separating adjacent limit sub-seats under the lower limit block 214, and the center of the partition plate 82 is provided with a first connecting rod 83 that can slide with the lower limit block 214, and the first spring The functional part is a first compression spring 80, which is sleeved outside the first connecting rod 83, and the upper end of the first compression spring 80 is connected to the bottom of the lower limit block 214, and the lower end of the first compression spring 80 is connected to the partition plate 82, and the partition plate 82 has a through hole 84. The head 83a of the first connecting rod 83 is connected to the through hole 84, and the tail 83b of the first connecting rod 83 is stuck outside the through hole 84, so that the size of the opening 215 can be changed when the inverted U-shaped bracket 8 drives the lower limit block 214 to slide.When the bracket is stationary relative to the upper limit blocks 213, the first orthopedic implant 110 is inserted into the openings 215 formed between the upper limit blocks 213 and the lower limit blocks 214, and the first orthopedic implant 110 can compress the lower limit block 214 to connect the first connecting rod 83 to move downward relative to the partition plate 82. At this time, the first compression spring 80 is in an energy storage state; and under the action of external force, the inverted U-shaped bracket 8 is driven to move downward to the partition plate 82, which can pull the first connecting rod 83 and the lower limit block 214 to move downward to the opening 215 between the upper limit block 213 to become larger, and the implant can fall out of the opening 215. Among them, at least one second connecting rod 87 is connected to the bottom of the partition plate 82 corresponding to the lower limit sub-block 214 located at the bottom, and the second connecting rod 87 can pass through the fixed plate 85 located at the bottom. The fixed plate 85 is covered with a second compression spring 86. The second compression spring 86 makes the fixed plate 85 and the second connecting rod 87 always have a tendency to reset upward, wherein the upper end of the second compression spring 86 is connected to the bottom of the partition plate 82, and the lower end of the second compression spring 86 is connected to the fixed plate 85. The length of the second compression spring 86 is greater than the first compression spring 80, so that when an external force is applied to the pressing part 81, each upper limit sub-block 213 and the lower limit sub-block 214 can switch to a free release state. Since the lengths of the second connecting rod 87 and the second compression spring 86 are greater than those of the first connecting rod 83 and the first compression spring 80, the force when the external force is applied to the pressing portion 81 must be sufficient to make the second connecting rod 87 move downward and press the second compression spring 86 downward until each partition plate 82 moves downward and the tail portion 83b of the first connecting rod 83 abuts against the peripheral portion of the through hole 84, thereby pulling the lower limit sub-block 214 connected thereto to move downward (such as. Fig.10 shown).

[0075] Taking the upper limit block 213 and the lower limit block 214 with three groups as an example, from top to bottom, there are the first upper limit block 213', the first lower limit block 214' and the first connecting rod 1 83' connected to the bottom of the first lower limit block 214'; the second upper limit block 213", the second lower limit block 214" and the first connecting rod 2 83" connected to the bottom of the second lower limit block 214"; the third upper limit block 213", the third lower limit block 214" and the first connecting rod 3 83"" connected to the bottom of the third lower limit block 214", and the inverted U-shaped bracket 8 includes the first connecting rod 1 83' The first partition plate 82 below, the second partition plate 82" below the first connecting rod 2 83" and the third partition plate 82"" below the first connecting rod 3 83"", the first connecting rod 1 83', the first connecting rod 2 83" and the first connecting rod 3 83" are all sleeved with a first compression spring 80, and the second connecting rod 83" is sleeved with a second compression spring 86, when an external force is applied to the pressing portion 81, the force must satisfy the first connecting rod 2 83" to move downward and press the second compression spring 86 downward to compress the first partition plate 82, the second partition plate 82" and the third partition plate 82" to move downward and the tail 83b of each connecting rod and the peripheral portion of the through hole 84 When the first and second connecting rods 83', 83' and 83' are in contact with each other, the first and second connecting rods 83', 83' and 83' are in contact with each other, and the first and second connecting rods 83', 83' are in contact with each other, and the first and second connecting rods 83', 83' are in contact with each other, and the first and second connecting rods 83', 83' are in contact with each other, and the first and second connecting rods 83' are in contact with each other. The opening 215 formed by 214´, the opening 215 formed by the second upper limit sub-block 213" and the second lower limit sub-block 214", and the opening 215 formed by the third upper limit sub-block 213"" and the third lower limit sub-block 214"" all become larger, so that the accepted implant falls out of the opening 215, and when the pressing portion 81 of the bracket is released from the external force, the above-mentioned openings 215 return to their original positions under the action of their respective first compression springs 80. When it is necessary to re-inspect the first orthopedic implant 110, it is only necessary to insert the first orthopedic implant 110 accordingly and fasten it in the above-mentioned opening 215 under the action of the first compression spring 80.

[0076] The acceptance and code affixing process is consistent with the process in Example 1 and will not be described in detail below. Example 3

[0077] The structure is basically the same as that of Example 2, with the only difference being that the lower edge of the upper limit block 213 is V-shaped, the upper edge of the lower limit block 214 is inverted V-shaped, and the lower edge of the upper limit block 213 has an upper notch 2131 that is concave upward from bottom to top at the tip of the V-shape, and the upper edge of the lower limit block 214 has a lower notch 2141 that is concave downward from top to bottom at the tip of the V-shape, and a space is formed between the upper notch 2131 and the lower notch 2141 for the first orthopedic implant 110 to be fixed. The positioning notch 2151 is formed in the upper and lower limit blocks 213 and 214, so that the first orthopedic implant 110 can be effectively positioned at the center of the upper limit block 213 and the lower limit block 214. In addition, if the first orthopedic implant 110 is inserted into the V-shaped inclined portion of the limit block 213 and the lower limit block 214, the first orthopedic implant 110 can slide to the center of the upper and lower limit blocks 213 and 214 due to gravity, so as to avoid the camera mechanism being unable to accurately scan the bar code corresponding to the first orthopedic implant 110, such as Fig.12 shown. Example 4

[0078] The preferred embodiment of the present invention is basically the same as the structure of embodiment 3, with the only difference being that the limit seats 2 are horizontally spaced along the circumference of the connector 5, the camera mechanism is located relatively above the limit seats 2, and as in embodiment 1, each row of limit seats is composed of at least two limit sub-seats spaced apart from each other, the limit sub-seats including a left limit sub-block 2130 and a right limit sub-block 2140, the left limit sub-block 2130 and the right limit sub-block 2140 together form a V-shaped opening whose horizontal spacing can be adjusted to accommodate the first orthopedic implant 110, such as Fig.14 shown. Example 5

[0079] like Figures 15 and 16As shown, the third way in which the first driving mechanism 4' of this embodiment is used to drive the relative movement between the limiting seat 2 and the camera mechanism 3 is: the first driving mechanism 4' drives the limiting seat 2 to move in the horizontal direction relative to the camera mechanism 3, the limiting seat 2 includes a base 200, an implant plate 2001 arranged above the base 200, and a support rod 12 connecting the base 200 and the implant plate 2001, the first driving mechanism 4 drives the limiting seat 2 to move in the horizontal direction relative to the camera mechanism through the third transmission mechanism 400, the third transmission mechanism 400 includes a frame 4001, two rollers 4002 arranged at the head and tail ends of the frame 4001, and a support rod 12 connecting the base 200 and the implant plate 2001. and a conveyor belt 4005 wound around the two rollers 4002 for conveying the limiting seat 2. The first driving mechanism 4' is provided with a third motor 4003 and a fourth motor 4004 on the outer side of the frame 4001 for driving the two rollers 4002 to rotate. The power output ends of the third motor 4003 and the fourth motor 4004 are respectively connected to the corresponding rollers 4002. The limiting seat 2 is driven to move through the conveyor belt 4005, so that the implants on the implant plates 2001 on each limiting seat 2 or the barcodes on the implant plates 2001 and the barcodes of the fixed angle shapes can be photographed by the camera mechanism, and then the acceptance of the implants is carried out. Example 6

[0080] The structure is basically the same as that of Example 5, with the only difference being that the limit seat 2 is not driven by the conveyor belt 4005 to move relative to the camera mechanism. When acceptance is required, it is directly placed under the camera mechanism such as the first camera unit 7, and the first camera unit 7 moves relative to the limit seat 2 (such as forward, backward, left, and right). In this embodiment, the forward, backward, left, and right movement of the first camera unit 7 relative to the limit seat 2 is achieved through the interaction of the first driving arm 7a and the second driving arm 7c that are connected to each other, wherein the first driving arm 7a and the second driving arm 7c are both driven by the motor 7b, such as Fig.17 shown. Example 7

[0081] The structure is basically the same as that of Example 1, with the only difference being that the acceptance personnel do not manually insert the first orthopedic implant 110 and the second orthopedic implant 120 into the limiting seat 2 and the connecting seat 201 one by one, but instead implement the operation through an automatic hand-lifting suction structure 90, wherein the hand-lifting suction structure 90 may adopt a vacuum suction method, such as including a main body 901 and a vacuum suction pipe 902 arranged on the main body and a pneumatic element connected to each vacuum suction pipe 902. In addition, an appearance acceptance module 500 is arranged below the hand-lifting suction structure 90 for detecting the shape, size and color of the orthopedic implant grasped by the hand-lifting suction structure 90, wherein the appearance acceptance module includes an acceptance seat 5001 with an open top, a camera unit 5002 arranged on at least one side wall of the acceptance seat 5001, and a circle of annular light sources 5003, such as Fig.13 As shown in the figure, the design of the appearance acceptance module is relatively simple. It only requires the camera to capture the appearance of a certain orthopedic implant under specific light, and then use the feature comparison method to determine whether the appearance of the accepted implant meets a certain appearance in the database. If an implant with inconsistent appearance characteristics such as color, size, and shape is encountered, an error message is output. Example 8

[0082] The structure is basically the same as that of Example 1, except that the microprocessor is connected to a display screen 100 arranged on one side of the acceptance device or through a good interface UI to display the acceptance results, and the acceptance personnel can analyze and record them.
