FIG. 1 is a block diagram showing an implant ordering system 100 according to an embodiment of the present application. The implant ordering system 100 includes an implant ordering device 10 and an implant ordering device 20.

<Implant ordering device>
The implant ordering device 10 includes an implant information storage unit 11, a patient information storage unit 12, an implant information display unit 13, a size prediction unit 14, and an ordering information transmission unit 15. The implant ordering device 10 can be composed of a personal computer (PC), a server device, a tablet terminal device, a computer such as a smartphone or a mobile phone, or a combination thereof that is communicably connected to each other.

The implant information storage unit 11 stores information on a plurality of implants used in orthopedic surgery. Implant information includes the implant part number, name, size, material, manufacturer, target body part, and price. The input of information about the implant into the implant information storage unit 11 can be performed by, for example, the manager of the implant ordering device 10 obtaining the information from the implant manufacturer and using a known input means. As known input means, for example, operations such as a keyboard and a mouse, flick input by a touch panel, voice input, file duplication from a storage medium, download from a network, and the like can be adopted. The implant information storage unit 11 can be composed of a known storage medium such as a hard disk drive, a CD-ROM, a CD-R, MO, a DVD, a USB memory, a flash memory, or a floppy disk.

The patient information storage unit 12 stores patient information including gender and height. Other patient information includes, for example, the age and weight of the patient, the date and time of surgery, an image of the affected area, a preoperative plan, and the like. As the affected part image, for example, an image taken by an ultrasonic (echo) examination, an X-ray (X-ray) examination, a CT (computed tomography) examination, an MRI (magnetic resonance imaging) examination, or the like can be considered. The patient information can be input to the patient information storage unit 12 by, for example, an orderer such as a doctor or a nurse using a known input means. The input of the affected area image to the patient information storage unit 12 is input from the inspection device via the local area network (LAN), input via the storage medium, and photographing by the image pickup device (camera) of the affected area image displayed on the display. Etc., a known input means can be used. The patient information storage unit 12 can be composed of a known storage medium like the implant information storage unit 11. The implant information storage unit 11 and the patient information storage unit 12 may be composed of one storage medium, each may be composed of one storage medium, or may be composed of a plurality of storage media.

The implant information display unit 13 displays information on a plurality of implants stored in the implant information storage unit 11. The implant information display unit 13 can be composed of a known display device such as a known display, monitor, projector, or printer. It is preferable that the implant information display unit 13 displays implant information so that an orderer such as a doctor can select the type of implant to be used in surgery from a plurality of implants. Types of implants include, for example, artificial joints, plates, and intramedullary nails. For example, even if the artificial joint is the same, if the manufacturer, name, and site used are different, different types of implants will be used.

The size prediction unit 14 can be adopted in surgery based on the patient information stored in the patient information storage unit 12 for the type of implant selected by the orderer among the plurality of implants displayed by the implant information display unit 13. Predict the size range of sexual implants. The implant information display unit 13 preferably displays a range of implant sizes predicted by the size prediction unit 14. The size prediction unit 14 can be composed of, for example, a memory for storing an instruction for size prediction and a central processing unit (CPU) for executing an operation for predicting a range of implant sizes according to the instruction. The specific prediction method will be described later.

The ordering information transmitting unit 15 provides information for specifying the type of implant selected by the ordering party and information for specifying the range of implant sizes predicted by the size predicting unit 14 to be adopted in surgery. The including order information is transmitted to the implant ordering apparatus 20 via the communication network N. The ordering information transmitting unit 15 operates the implant ordering device 10 to select the implant size, in addition to the implant size range predicted by the size predicting unit 14 to be adopted in surgery. The specifying information may also be transmitted to the implant ordering device 20. Further, the ordering information transmitting unit 15 operates the implant generator 10 to exclude the implant from the range of the implant size predicted by the size predicting unit 14 in the surgery. Except for the size, information specifying the size of the remaining implants may be transmitted to the implant ordering device 20. A known communication interface can be used as the ordering information transmitting unit 15. As the information for specifying the type of implant, any information or any combination can be adopted from the information stored as the implant information in the implant information storage unit 11. The ordering information transmitted by the ordering information transmitting unit 15 may include, for example, the date and time when the information for identifying the implant is transmitted, the information about the ordering party, the information about the attending physician, the delivery date, the scheduled surgery date, and the like. .. As the communication network N, for example, the Internet, a wide area network (WAN), a local area network (LAN), or the like can be used. The implant ordering device 10 preferably has an ordering information storage unit (not shown) that stores the ordering information transmitted by the ordering information transmitting unit 15. The ordering information storage unit can be configured from a known storage medium, similarly to the implant information storage unit 11.

According to the implant ordering device 10 described above, it is possible to easily order necessary and sufficient implants. In addition, it is possible to prevent the occurrence of communication errors between the orderer and the contractor.

The size prediction unit 14 uses a learning model generated by machine learning using the data of the type and size of the implant adopted in the past surgery and the patient data including the sex and height of the patient who has undergone the past surgery as teacher data. It is preferable to calculate the range of implant sizes that may be adopted. As a result, doctors, nurses, etc. can predict the range of implant size required for surgery and place an order by inputting patient information into the implant ordering device 10 without considering the size of the implant required for surgery. Is possible. There is a correlation between patient gender and height and implant size: males are more likely than females to have larger implants, and taller ones are more likely to have larger implants. The patient's age and weight can be used as confounding factors to improve the accuracy of prediction.

The learning model can be generated using, for example, the neural network 30 shown in FIG. The neural network 30 has an input layer 31, an intermediate layer 32, and an output layer 33. The number of intermediate layers 32 is not limited to two. The input layer 31, the intermediate layer 32, and the output layer 33 are each composed of nodes 34 represented by circles, and each node 34 of the input layer 31, the intermediate layer 32, and the output layer 33 is connected to the node 34 of the adjacent layer by a synapse 35. Is done. Patient information and implant types of patients who have undergone surgery in the past are input to the input layer 31, and a range of implant sizes that may be adopted in the surgery is output from the output layer 33. Generating a learning model by performing machine learning that adjusts the weight of the synapse 35 so that the implant size range output from the output layer 33 approaches the implant size range adopted in previous surgery. Can be done. Machine learning can be done with existing software such as TensorFlow®. The learning model may further calculate the probability of being adopted in surgery for each size of implant. In this case, the patient information of the patient who has undergone the operation in the past and the type and size of the implant are input to the input layer 31, and the size of the implant input to the input layer 31 is adopted from the output layer 33 in the operation. The probability is output. A learning model can be generated by performing machine learning that adjusts the weight of the synapse 35 so that the probability output from the output layer 33 approaches the adoption probability in the past surgery.

However, the size prediction by the size prediction unit 14 is not limited to the one using the learning model. For example, the size prediction unit 14 uses patient data of patients who have undergone surgery in the past to match the type of implant used in the surgery with the gender of the patient undergoing surgery, and the difference in height is within a predetermined range in the past. The range of implant sizes adopted for the patient and the size within a given additional range may be predicted as the range of implant sizes that may be adopted. For example, if the type of implant used in surgery matches the gender of the patient undergoing surgery and the height difference is within a predetermined range, the size range of implants used in surgery for past patients may be 50 mm to 60 mm. For example, it may be predicted that an implant having a size of 45 mm to 66 mm may be adopted, including an additional range of 10% above and below. If the type of implant used in surgery matches the gender of the patient undergoing surgery and the number of data for past patients whose height difference is within a predetermined range is small, the additional range should be increased to the past. If the number of patient data is large, the additional range can be reduced. The point that the additional range can be determined is the same when the learning model is used.

When predicting the size range of the implant by the learning model, the patient information stored in the patient information storage unit 12 further includes the patient's affected area image, and the patient data as teacher data includes the affected area image of the patient who has undergone past surgery. It is preferable to include more data. As a result, the patient information and the affected area image data can be used to generate a learning model, and the implant size range can be predicted based on the patient information and the affected area image, and the prediction accuracy of the implant size range can be improved.

The implant ordering device 10 stores in the patient information storage unit 12 information for specifying the type of implant included in the ordering information transmitted by the ordering information transmitting unit 15 and information for specifying the size of the implant adopted in the operation. It is preferable to further have a recruitment information storage unit 16 that stores the information in association with or together with the patient information. As a result, data that can be used to improve the accuracy of size prediction by the size prediction unit 14 can be accumulated. The adopted information storage unit 16 can be configured from a known storage medium like the implant information storage unit 11. The implant information storage unit 11, the patient information storage unit 12, and the recruitment information storage unit 16 may be composed of one storage medium, one storage medium, or a plurality of storage media. It may be composed of a medium.
