It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.
The embodiment of the invention provides an information management method of surgical instruments, which is applicable to verification of instrument information before surgery and update of instrument information after surgery. The two communication parties of the method are a control system in medical equipment and a storage module in surgical equipment; the surgical instrument is used as a consumable in the surgical process, has a plurality of different instrument types, corresponds to different instrument functions, and can be detachably connected with medical equipment. Fig. 1 is a flowchart of a method for managing information of a surgical instrument according to an embodiment of the present invention. As shown in fig. 1, for a control system in a medical device, the information management method of the surgical instrument includes the steps of:
s110, under the condition that the surgical instrument is determined to be mounted on the medical equipment, sequentially sending a plurality of verification information reading instructions to a storage module of the surgical instrument, and verifying the qualification of the surgical instrument according to each piece of verification information returned by the storage module; the verification information comprises anti-counterfeiting identification information, instrument coding information and instrument type information of the surgical instrument.
The storage module can be a storage chip built in the surgical instrument, and the anti-counterfeiting identification information, the instrument coding information and the instrument type information can be stored in the storage module of the surgical instrument before leaving the factory. The anti-counterfeiting identification information can be a ROM code of a memory chip, the ROM code can take an encrypted specific coding form, and the anti-counterfeiting identification information of each surgical instrument is provided with a globally unique serial number to serve as an anti-counterfeiting mark. The instrument coding information can comprise the production date, the production batch and the like of the surgical instrument, and the instrument coding information can also adopt an encrypted specific coding form to realize the encryption protection of the surgical instrument; the control system can trace the source by decoding the encoded information of the instrument so as to trace the production process of the instrument and the cause of the problem when the surgical instrument has the problem. The instrument type information may be used to indicate the type, model, use, etc. of the instrument so that the control system determines whether the surgical instrument mounted on the medical device matches the current operating requirements of the current procedure.
The qualification checking of the surgical instrument, namely the checking process of the checking information stored in the storage module, can preliminarily judge that the surgical instrument is qualified when the anti-counterfeiting identification information, the instrument coding information and the instrument type information are all checked; when the at least one item of verification information fails to pass the verification, the surgical instrument can be judged to be unqualified, and the surgical instrument can be eliminated. The verification of the anti-counterfeiting identification information can be understood as the verification of the ROM code of the memory chip, which indicates that the instrument is a product of the company; the fact that the instrument coding information passes the verification can be understood as that the production date of the instrument passes the verification, and the instrument is guaranteed; the instrument type information can be understood by verification to determine that the surgical instrument matches the current operating requirements of the current procedure.
And S120, when all the verification information passes the verification, sending a service life information reading instruction to the storage module, and receiving service life information of the surgical instrument returned by the storage module.
When all the verification information passes the verification, the surgical instrument can be primarily judged to be qualified, and whether the surgical instrument is available in the current operation can be subsequently judged according to the service life information of the surgical instrument. For example, the lifetime information may include a remaining number of uses of the surgical instrument, and the total number of uses allowed by the surgical instrument may be stored in the storage module in advance before the surgical instrument leaves the factory.
And S130, when the service life information meets the use condition of the surgical instrument, controlling the operation of the surgical instrument, updating the service life information according to the operation time of the surgical instrument in the current operation, and sending a service life information writing instruction to the storage module so that the storage module updates the service life information stored by the storage module.
The use conditions of the surgical instrument can be as follows: the remaining use times of the surgical instrument reach the use requirement of the operation, for example, the remaining use times are more than 0. When the life information satisfies the conditions of use of the surgical instrument, the control system may determine that the surgical instrument is available and control the operating state of the surgical instrument according to the operation command of the operator.
The service life information is updated according to the running time of the surgical instrument in the current operation, and the service life information can be specifically: the operation time of the surgical instrument is recorded from the beginning of the operation, and when the operation time of the surgical instrument reaches the life adjustment time, the remaining use times of the surgical instrument are reduced by 1. The life information can also comprise the life adjustment time, and the control system can acquire the residual use times and the life adjustment time simultaneously when acquiring the life information and update the residual use times of the surgical instrument based on the operation time and the life adjustment time of the surgical instrument. For example, the lifetime adjustment time may be stored in a memory module of the surgical instrument before the surgical instrument leaves the factory. For example, the life test can be performed after the production of the surgical instrument to determine the ultimate service life of the surgical instrument, and the life adjustment time of the surgical instrument can be relatively and conservatively determined as the basis of subtracting 1 from the single residual use time of the instrument by combining the target use times of the surgical instrument and the possible duration of using the instrument in one operation on the basis of the ultimate service life so as to ensure the use safety of the instrument.
The storage module updates the stored life information, namely, the storage module adopts the updated life information of the control system to cover the life information stored before the storage module according to the writing instruction of the life information, so that the control system can read the latest life information when the surgical instrument is installed on the medical equipment next time.
In the information management method of the surgical instrument provided by the embodiment of the invention, the qualification of the surgical instrument is firstly checked based on a series of check information in the surgical instrument, whether the surgical instrument is a qualified product can be determined according to the anti-fake identification information, whether the surgical instrument is safe or not can be determined according to the instrument coding information, and whether the surgical instrument is matched with the type requirement of the current surgical instrument can be determined according to the instrument type information. After the series of verification information passes the verification, the service life information of the surgical instrument is verified, and whether the surgical instrument meets the use requirement of the current operation can be determined. When all information of the surgical instrument passes the verification, the operation of the surgical instrument is controlled, so that the use safety of the surgical instrument can be ensured, and the operation safety is ensured. And, the automatic recognition based on the control system makes the verification more reliable than the visual recognition based on the operator. And updating the life information stored by the storage module according to the operation time of the surgical instrument in operation, thereby being beneficial to the control system in the next operation to acquire the correct life information of the surgical instrument. Therefore, compared with the prior art, the embodiment of the invention can perfect the information management method of the surgical instrument and improve the safety of the operation.
Based on the above embodiments, optionally, the specific execution process of the qualification checking of the surgical instrument is various, and one of the specific checking processes is described below with reference to fig. 2. Referring to fig. 2, in one embodiment, optionally, the qualification checking of the surgical instrument specifically includes:
s11, sending a first check information reading instruction to the storage module, and receiving anti-counterfeiting identification information returned by the storage module.
S12, judging whether the anti-counterfeiting identification information passes verification; if yes, executing S13; if not, S18 is performed.
For example, based on the material management requirements of the surgical procedure, the anti-counterfeiting identification information of each surgical instrument can be collected and stored after a batch of surgical instruments is received, and an anti-counterfeiting information base can be formed in the control system. Then, the step can directly check the anti-counterfeiting identification information of the surgical instrument by confirming whether the anti-counterfeiting identification information is in the anti-counterfeiting information base.
S13, sending a second check information reading instruction to the storage module and receiving the instrument coding information returned by the storage module.
S14, judging whether the instrument coding information passes the verification; if yes, executing S15; if not, S18 is performed.
The method specifically comprises the following steps: decoding the instrument coding information, acquiring the production date and the shelf life of the instrument, and determining whether the instrument coding information passes the verification by confirming whether the instrument is currently in the shelf life.
S15, sending a third check information reading instruction to the storage module, and receiving instrument type information returned by the storage module.
S16, judging whether the instrument type information passes verification; if yes, executing S17; if not, S18 is performed.
The method specifically comprises the following steps: decoding instrument type information to obtain the type and model of the instrument; and determining whether the instrument type information passes the verification by confirming whether the type and the model of the instrument meet the current operation requirement of the current operation.
S17, judging that the surgical instrument is qualified.
S18, judging that the surgical instrument is unqualified.
In the embodiment, the qualification of the surgical instrument is checked through S11-S18. Specifically, in this embodiment, anti-counterfeit identification information, instrument coding information and instrument type information of the surgical instrument are sequentially checked, and when all types of check information pass the check, the surgical instrument is judged to be qualified; when any type of verification information does not pass the verification, the failure of the surgical instrument can be judged, and the verification of other types of verification information can be omitted.
The above verification sequence is only exemplary, and is not intended to limit the present invention. In other embodiments, the execution sequence and the content of each step can be optionally changed according to the requirement. For example, the instrument type information may be checked first, or the instrument code information may be checked first.
In another embodiment, optionally, the control system may further transmit various verification information reading instructions to the storage module, and after receiving all the verification information returned by the storage module, perform the instrument eligibility verification based on all the verification information. For example, the verification of various types of verification information can be performed synchronously in parallel.
The above embodiments describe the core concept of the information management method. Next, in combination with a specific structure of the control system, a specific description is given of an information interaction process between each component in the information management process.
On the basis of the above embodiments, optionally, the control system includes: and the control master station and the control slave station are connected with each other. The control master station is arranged in a central control machine of the medical equipment, and the control slave station is arranged in a mechanical arm of the medical equipment, so that the central control machine can uniformly regulate and control all the mechanical arms. The medical device is, for example, a surgical robot applied to minimally invasive surgery.
The control master station is used as a core module for data processing in the whole medical equipment, and the control slave station is used as a signal interaction medium between the control master station and the storage module. Specifically, the control master station is used for generating various instructions such as a verification information reading instruction, a service life information writing instruction and the like; checking the qualification of the surgical instrument according to each piece of checking information; and controlling operation of the surgical instrument when the life information meets the use condition of the surgical instrument, and updating the life information of the surgical instrument according to the operation time of the surgical instrument in the current operation. The control slave station is used for transmitting the verification information reading instruction, the service life information reading instruction and the service life information writing instruction generated by the control master station to the storage module, and transmitting feedback information provided by the storage module based on the instruction, such as anti-counterfeiting identification information, instrument coding information, instrument type information, service life information and the like, to the control master station.
Specifically, a complete information interaction process may be: the control master station transmits command signals to the control slave stations, the control slave stations convert the command signals into corresponding command signals and transmit the corresponding command signals to the storage module, the storage module returns corresponding data signals to the control slave stations according to the command signals, and the control slave stations convert the data signals into signal formats between the data signals and the control master stations and then return the data signals to the control master stations.
Illustratively, the structure for controlling signals transmitted between the master station and the slave station comprises: a start bit, a type bit, a data bit, and a check bit. Wherein the start bit is used as a data head of the signal, and the data of the start bit can be used for identifying the start of the transmission of the signal and identifying the source of the signal. The data of the type bit may be used to indicate the request type of the signal, e.g. read or write. The data of the data bits may be specific data that needs to be transmitted. The data of the check bit can be determined according to the sum of the data of the type bit and the data of the data bit and used as a check code between the control master station and the control slave station; therefore, the receiving end can check command intention and specific content simultaneously based on the data of check bits, and a better check effect on the communication process between the master station and the slave station is realized. For example, the signal transmitted between the control master and the control slave may consist of 32 bits of data, the first 8 bits of the data being the start bits, the next 8 bits being the type bits, the next 8 bits being the bit data bits, and the last 8 bits being the check bits. Wherein the data of the check bit is obtained by adding the data of the middle two 8 bits, when the data of the middle two 8 bits are added to exceed 8 bits, the exceeding part can be abandoned, and only the data of the last 8 bits can be reserved as the data of the check bit.
On the basis of the above embodiments, the storage module optionally includes 4 storage addresses (or 4 storage pages) for storing the anti-counterfeiting identification information, the instrument code information, the instrument type information and the lifetime information, respectively. In the information reading and writing process, specific information to be read or written can be determined by specifying a required storage address. The anti-counterfeiting identification information, the instrument coding information and the instrument type information are set as read-only information, so that storage pages corresponding to the information are configured as encryption pages, and the user is prevented from tampering with the description information.
The command signals for controlling the transmission from the slave station to the memory module may include: the memory address, instruction specific content and check code. Wherein, the storage address represents the storage address in the storage module corresponding to the instruction signal; the instruction concrete content indicates whether the instruction is read or write, and when the instruction is write, the instruction concrete content also comprises concrete data which needs to be written into a corresponding storage address; the check code is used to confirm whether there is a problem controlling the communication between the secondary station and the memory module.
On the basis of the above embodiments, optionally, the storage form of the lifetime information in the storage module adopts binary coding, and the data in the lifetime information is set to be changed from 1 to 0 only and not from 0 to 1, so as to avoid error operation of adding the lifetime information by a user. Then, the number of 1's in the binary code indicates the remaining number of uses of the surgical instrument. Accordingly, the step of updating the lifetime information may specifically be: when the remaining number of uses of the surgical instrument needs to be reduced by 1, the last 1 in the lifetime information is replaced by 0. The last 1 in the lifetime information is the last 1 in the current lifetime information, for example, the lifetime information before the 1-subtracting operation is 11111000, then the 1-subtracting operation needs to replace the 1 in the fifth bit from left to right with 0, and the lifetime information after the 1-subtracting operation is updated to 11110000, which indicates that the remaining number of uses of the surgical instrument is 4.
On the basis of the above embodiments, optionally, the medical device further includes a switch module, which is disposed in the mechanical arm and is connected to the control slave station. When the surgical instrument is mounted on the medical equipment, the storage module is connected with the control slave station, and meanwhile, the surgical instrument can trigger the switch module to change the switch state of the switch module, so that the control slave station confirms whether the surgical instrument is mounted according to the switch state of the switch module. Then, determining that the surgical instrument is mounted on the medical device may specifically include: when the control slave station detects that the switch module is triggered, transmitting an instrument installation signal to the control master station; the control master station determines that the surgical instrument is mounted on the medical device according to the instrument mounting signal. When the control slave station detects that the switch module is not triggered, the control slave station can directly judge that the surgical instrument is not installed. For example, the switch module may be a HALL (HALL) switch, and a magnetic element may be disposed in the surgical instrument, and when the surgical instrument is mounted on the medical device, the magnetic element may trigger the HALL switch to conduct, and transmit a conduction state signal to the control slave station to inform the control slave station that the switch module has been triggered.
The control flows for controlling the master station and the slave stations during a data interaction are exemplarily described below with reference to fig. 3-4.
