The present disclosure relates to an audio and video collection device, and in particular, a surgical audio and video collection device.
The development of technology has made the collection of surgical audio and video easier. Surgical video may provide a record of an operation scene, and has been adopted as an important means for learning, teaching and academic activities among medical personnel. Surgical video helps resident physicians and researchers to learn the details of surgery and observe the actual operation of surgical instruments.
Based on the relationship between the video camera, the surgical equipment and the surgical operator, the surgical audio and video collection device is divided into the following three categories: non-integrated, operator-integrated and equipment-integrated. Among them, the operator-integrated type of surgical audio and video collection device mainly performs video recording by fixing the video camera on the body of the surgical operator, thereby providing surgical audio and video from the first perspective.
The present disclosure provides a surgical audio and video collection device, which may solve existing defects.
A surgical audio and video collection device of the disclosure includes a processor, a video camera and a skin-touch vibration pickup. The video camera electrically connected to the processor is configured to be worn on the body of the surgical operator and record video. The skin-touch vibration pickup is configured to be attached on the skin of the surgical operator and sense the vibration of the skin to pick up the sound. The skin-touch vibration pickup is signally connected to the processor to transmit voice message to the processor. The voice message includes at least one of voice commands for controlling the video camera and voice tags for being added to the video recorded by the video camera.

In an embodiment of the disclosure, the surgical audio and video collection device further includes an earphone, which is configured to be worn on or around the ear of the surgical operator, to receive an external sound source and transmit the external sound source to the ear of the surgical operator.
In an embodiment of the present disclosure, the earphone is an osteoconductive earphone.
In an embodiment of the disclosure, the surgical audio and video collection device further includes a host, and the host has a processor, and the earphone receives an external sound source from the host.
In an embodiment of the disclosure, the surgical audio and video collection device further includes a host, and the host has a processor, the video camera transmits the video to the host, and the skin-touch vibration pickup transmits voice commands to the video camera through the host.
In an embodiment of the disclosure, the skin-touch vibration pickup transmits voice messages externally through the host.
In an embodiment of the disclosure, the surgical audio and video collection device further includes a high-frequency microphone, which is electrically connected to the host.
In an embodiment of the disclosure, the surgical audio and video collection device further includes a wireless transceiver. The video camera is electrically connected to the wireless transceiver and transmits the video to the host through the wireless transceiver. The skin-touch vibration pickup is electrically connected to the wireless transceiver and transmits voice messages to the host through the wireless transceiver.
In an embodiment of the disclosure, the surgical audio and video collection device further includes a host, and the host has a processor. The video camera transmits the video to the host, and the skin-touch vibration pickup transmits a voice tag to the host.
In an embodiment of the disclosure, the surgical audio and video collection device further includes a high-frequency microphone, which is electrically connected to the processor.
Based on the above, in the surgical audio and video collection device of the present disclosure, the surgical operator may voice control the video camera or add voice tags to the video. Therefore, the surgical audio and video collection device of the present disclosure has the advantage of being easy to control.
In the surgical audio and video collection device 100 of this embodiment, the skin-touch vibration pickup 120 is configured to pick up sound. That is, unlike the general microphone that senses air vibration caused by the sound, the skin-touch vibration pickup 120 senses the vibration generated by the skin attached thereto when the surgical operator 50 speaks. Therefore, even in a situation where the ambient sound of the operation scene is noisy, the content of speech delivered by the surgical operator 50 may still be accurately received by the skin-touch vibration pickup 120. Thus, the processor 105 may receive voice messages from the skin-touch vibration pickup 120.
When the processor 105 determines that the voice message includes a voice command for the video camera 110, the processor 105 transmits the voice command to the video camera 110, and the video camera 110 starts video recording, pauses video recording, ends video recording or perform other actions according to the commands. In this way, not only can the surgical operator 50 have more control over the video camera 110, but also there is no need to set foot pedals that become obstacles for the surgical operator.
On the other hand, the voice message may further include a voice tag in the video recorded by the video camera 110. For example, when the processor 105 determines that the voice message contains preset keywords, such as “here is the key point”, “this is the beginning of the key point”, “this is the end of the key point”, etc., a tag is added at the corresponding section in the video recorded by the video camera 110. In this way, when viewing the video recorded by the video camera 110 in the future, it is easy to quickly find the section of the key segment, so as to improve the practicability of the video. The preset keywords described herein may be built-in in the system, but may also be set by users to improve flexibility.
In this embodiment, the surgical audio and video collection device 100 further includes a headband 130, and the video camera 110 is mounted on the headband 130. The headband 130 may be an elastic band, or a belt whose length is adjusted by using buttons, velcro tape or other methods, or a steel ring or other suitable forms. In this embodiment, the skin-touch vibration pickup 120 is mounted on the headband 130 and configured to contact the head of the surgical operator 50. In other words, the headband 130 may provide an appropriate force to press the skin-touch vibration pickup 120 against the head of the surgical operator 50. Here, although it is described that the skin-touch vibration pickup 120 contacts the head of the surgical operator 50, the two are not limited to be in direct contact, and there may be surgical caps or other objects arranged between the two, as long as the skin-touch vibration pickup 120 can pick up sound correctly.
In this embodiment, the skin-touch vibration pickup 220 is in contact with the neck of the surgical operator 50. Because the head of the surgical operator 50 normally wears a surgical cap and the neck is normally bare, the skin-touch vibration pickup 220 is more likely to be in direct contact the skin of the neck, thereby obtaining a better sound pickup effect.
In the present embodiment, the surgical audio and video collection device 200 further includes an earphone 250 configured to be worn on or around the ears of the surgical operator 50 to receive external sound sources and transmit external sound sources to the ears of the surgical operator 50. For example, the earphone 250 may communicate with a mobile phone or other devices, so the surgical operator 50 may receive the voice of the personnel outside the operating room through the earphone 250. In this embodiment, the earphone 250 may be an osteoconductive earphone. Therefore, the earphone 250 may transmit sound to the ears of the surgical operator 50, and the ears of the surgical operator 50 may still receive the sounds of personnel and equipment in the operating room.
In this embodiment, the surgical audio and video collection device 200 further includes a host 260. The host 260 has a processor 105. The earphone 250 receives an external sound source from the host 260. Communication between the earphone 250 and the host 260 may be performed in a wired or wireless manner.
In this embodiment, the video camera 110 may transmit video to the host 260, and the host 260 stores and/or transmits the video. In the embodiment shown in
On the other hand, the voice message recorded by the skin-touch vibration pickup 220 may be determined by the processor 105 of the host 260 whether the voice message contains a preset keyword. When it is determined that the voice message contains a preset keyword, a tag is added at the corresponding section in the video recorded by the video camera 110. However, the voice message recorded by the skin-touch vibration pickup 220 may also be directly transmitted to the video camera 110, and the processor in the video camera 110 determines whether the preset keyword is included. When it is determined that the voice message contains the preset key, a tag is added at the corresponding section in the video recorded by the video camera 110.
In this embodiment, the skin-touch vibration pickup 220 may further transmit voice messages externally through the host 260. In addition, the earphone 250 may receive an external sound source through the host 260 and transmit the external sound source to the ears of the surgical operator 50. Therefore, the surgical operator 50 uses the skin-touch vibration pickup 220 and the earphone 250 to communicate with the personnel outside the operating room through the host 260.
In this embodiment, the surgical audio and video collection device 200 further includes a high-frequency microphone 270, which is electrically connected to the processor 105 of the host 260. For example, the high-frequency microphone 270 may include a microphone and a filter. After the microphone picks up the sound, the low-frequency part is filtered out by the filter and the high-frequency part is retained. The skin-touch vibration pickup 220 mainly picks up the low-frequency part of the sound, while the high-frequency microphone 270 may pick up the high-frequency part of the sound. In this way, it is possible to avoid recording the ambient noise, and the high-frequency part of the sound such as breath sounds emitted by the surgical operator 50 may be supplemented. Therefore, the accuracy of the recognition of the voice message may be improved, and when the surgical operator 50 carries out communication through the host 260, the sound transmitted to the outside has better fidelity.
In other embodiments, the high-frequency microphone 270 of the surgical audio and video collection device may also be electrically connected to the processor of the video camera 110, and the audio recording results thereof may be used for voice-controlling the video camera 110 or stored by the processor of the video camera 110.
To sum up, in the surgical audio and video collection device of the present disclosure, the skin-touch vibration pickup senses the vibration of the skin of the surgical operator to pick up sound. Therefore, the surgical operator may easily control the surgical audio and video collection device or add voice tags to the recorded video.
