Light detection module and transport module are arranged between base and half ball cover.Wherein light detection module includes transmittingDevice 210 and reception device 220；The light of emitter transmitting is directed toward manual acetabulum；Reception device receiving and transmitting unit is launchedLight.Specifically, emitter includes but not limited to infrared transmitter or laser emitter, and reception device includes but unlimitedIn infrared remote receiver or laser pickoff.In one embodiment, emitter includes single transmitter or encodedTransmitter array, reception device includes single receiver or encoded receiver array.
Specifically, light detection module is used to generate light detection information, and sends light by the transport module and detectInformation is to processing module；Processing module receives light detection information, and whether determines bulb prosthese according to the light detection informationDislocation；When bulb prothesis dislocation, prompt message is sent to reminding module, so that the reminding module is prompted.
Wherein, transport module includes Wi-Fi (Wireless-Fidelity, Wireless Fidelity) module, 4G modules, GPRS(General Packet Radio Service, general packet radio service) module, Sub-1G wireless modules, 433M is wireless mouldOne or more in block or ethernet module.Certainly, which can also be wire transmission module, such as pass throughUSB serial line interfaces realize data transfer.Above-mentioned reminding module includes warning device or display device.The warning device can bePhonetic alarm, buzzer or indicator light.The processing module can be provided with corresponding software host computer or otherHost computer.
Specifically, testing principle is as follows：
Referring to Fig. 4, since the inner surface of normal condition lower semisphere cover and manual acetabulum fits together, when emitter refers toDuring to manual acetabulum, emitter send light by half transparent ball cover after, directly arrival manual acetabulum inner surface, peopleThe nontransparent material of work acetabular bone, therefore light can be reflected, the light after reflection is received device reception.Referring to Fig. 5, work as ballWhen with manual acetabulum dislocation phenomenon occurs for head prosthesis, the inner surface of half ball cover and manual acetabulum can produce gap, emitter hairAfter the light sent is by half transparent ball cover, after being reflected into gap, the inner surface of manual acetabulum is then reached again, at this timeThe inner surface of situation about fitting together compared to the inner surface of half ball cover and manual acetabulum, half ball cover and manual acetabulum can produceDuring gap, the light path formed by light can change because of gap, and the light that reception device receives can shiftSo that it is determined that dislocation phenomenon occurs and then is prompted.Such as the light 1 (solid line expression) in Fig. 5 for half ball cover and manual acetabulumLight path situation when inner surface fits together, the light 2 (dotted line expression) in Fig. 5 are half ball cover and the inner surface of manual acetabulumSituation during gap can be produced.
Based on above-mentioned testing principle, an embodiment of the present invention provides following several ways to carry out dislocation detection：
The first, emitter includes single transmitter, and reception device includes single receiver.
Referring to Fig. 6, when the inner surface of half ball cover and manual acetabulum fits together, the transmitting dress in light detection moduleAfter putting transmitting light, after half ball cover arrival manual acetabulum inner surface is reflected, received by half ball cover and by receiverLight 1 (part that solid line represents in Fig. 6).When dislocation phenomenon occurs for bulb prosthese and manual acetabulum, what emitter was sentAfter light is by half transparent ball cover, after being reflected into gap, the inner surface of manual acetabulum is then reached again, by artificialLight 2 (in Fig. 6 dotted line represent part) after the inner surface reflection of acetabular bone compared to before dislocation there occurs light offset, at this timeReceiver cannot receive light.I.e. light detection module cannot sense complete light path, and generation represents light offsetFor light detection information to processing module, processing module control reminding module, prompts bulb prosthese and manual acetabulum generation dislocation existingAs either default ideal position shifts before.
Second, emitter includes single transmitter, and reception device includes encoded receiver array.
Referring to Fig. 5, when the inner surface of half ball cover and manual acetabulum fits together, light that receiver array receivesAs shown in solid lines in fig. 5.When dislocation phenomenon occurs for bulb prosthese and manual acetabulum, the light that receiver array receives is sent outRaw offset, as shown in broken line in fig. 5, that is, before and after dislocating, receives light by the different receivers in receiver array respectively.
Light sensing module obtains the mark (hereinafter referred to as transmitter mark) of the transmitter of transmitting light and receives lightReceiver mark (hereinafter referred to as receiver mark), according to the transmitter mark and receiver mark generation light detection letterBreath, which is sent to processing module.
Since receiver array is encoded, can determine to dislocate with encoded information and light detection informationThe position (receiving position) of receiver in detection.Further, transmitter is stored with processing module and identifies corresponding transmittingThe position (launching position) of device, and the emitter and the position correspondence relation of reception device demarcated in advance.Such as the hair of a positionsDuring the receiver of emitter corresponding A position, represent that with manual acetabulum phenomenon of dislocating does not occur for bulb prosthese；When the transmitter of a positionsThe receiver of corresponding B location, i.e., when being no longer ideal position (location A) demarcated originally, represent bulb prosthese in manual acetabulumIn departing from ideal position, dislocation phenomenon occurs.
Therefore, after processor module gets the light detection information for carrying transmitter mark and receiver mark,Bulb prosthese and people can be determined in a manner of directly by searching for the position correspondence relation of position and emitter and reception deviceThe relative position of work acetabular bone, determines whether dislocation phenomenon occur.
Further, in a possible embodiment, which can launch the light of a variety of different angles, eachThe light of angle is provided with numbering by precoding.Transmitter is stored with processing module and identifies corresponding transmitting position, andThe launch angle for the transmitter demarcated in advance and the position correspondence relation of reception device.By taking three kinds of angles as an example, such as the light of a anglesThe receiver of line corresponding A position, the light of b angles correspond to the receiver of B location, and the light of c angles corresponds to the receiver of location of CWhen, represent that with manual acetabulum phenomenon of dislocating does not occur for bulb prosthese；And when the light of a angles corresponds to the receiver of D positions, b anglesThe light of degree corresponds to the receiver of E positions, when the light of c angles corresponds to the receiver of F positions, represents bulb prosthese and artificialThe relative position of mortar shows as No. 001 position, and dislocation phenomenon occurs；Or when the light of a angles corresponds to the receiver of G positions, bThe light of angle corresponds to the receiver of H positions, when the light of c angles corresponds to the receiver of I positions, represent bulb prosthese with manuallyThe relative position of acetabular bone shows as No. 002 position, and dislocation phenomenon occurs.
The third, emitter includes encoded transmitter array, and reception device includes encoded receiverArray.
Specifically, this mode is similar with the above-mentioned second way, and transmitter is added on the basis of the second wayNumber, to form transmitter array, as shown in Figure 4, transmitter array can launch a plurality of light, so can be more accurateThe relative position of true definite head prosthesis and manual acetabulum.
It is similar with the second way in concrete implementation process, difference lies in processing module by transmitter codes information,Receiver coding information and light detection information determine the position of transmitter and receiver in dislocation detection.In addition, processing moduleIn be stored with the position correspondence relation of the emitter demarcated in advance and reception device.Such as the transmitter corresponding A position of a positionsDuring receiver, and when the transmitter of b positions corresponds to the receiver of B location, represent that bulb prosthese is not dislocated with manual acetabulumPhenomenon；When the transmitter of a positions corresponds to the receiver of location of C, when the transmitter of b positions corresponds to the receiver of D positions, representThe relative position of bulb prosthese and manual acetabulum shows as No. 001 position, and dislocation phenomenon occurs；When the transmitter of a positions corresponds to EDuring the receiver of position, when the transmitter of b positions corresponds to the receiver of F positions, the opposite of bulb prosthese and manual acetabulum is representedPosition shows as No. 002 position, and dislocation phenomenon occurs.
Therefore, whether processing module can be dislocated by following steps come the bulb prosthese determined in manual acetabulum：
(a) determine to send position according to light detection information and receive position.Wherein light detection information includes transmitterMark, receiver mark.
(b) according to sending position, receive position and the emitter and the position correspondence relation of reception device demarcated in advance,Determine the relative position of bulb prosthese and manual acetabulum.
That is, according to above-mentioned introduction, according to sending position and receiving position, search the emitter demarcated in advance and filled with receivingThe position correspondence relation put, so that it is determined that going out the relative position of bulb prosthese and manual acetabulum.
(c) according to relative position, determine whether the bulb prosthese in manual acetabulum dislocates.
It should be noted that during the present invention realizes dislocation detection, the solution of above-mentioned location position can be not limited toCalculation mode, can also such as determine the relative position of bulb prosthese and manual acetabulum by way of specifically the Calculation of Optical Path, thisIn be not construed as limiting.
