Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an externally powered detection head. Background Art

[0002] At present, the cervical opening of pregnant women is checked by manual fingers. Because the finger sizes of different doctors are different, the test results are also different. At the same time, doctors are often required to check frequently before delivery, which will cause a very poor experience for pregnant women and increase the pain and infection rate of pregnant women. Therefore, inventing an accurate prenatal detection instrument to replace manual finger examination has become a research direction in this field.

[0003] For example, the Chinese patent with patent number CN202211239837.2 discloses a prenatal detection instrument and detection system, which can be used to replace fingers to check the cervical opening and other conditions. However, the detection instrument of the prior art is powered by a battery installed inside, and the battery also needs to be connected to the capsule endoscope through a power supply column. Due to the need to control the size of the entire instrument, a separate power supply battery is set in the detection instrument. It is inevitable that the capacity of the battery cannot be designed to be too large, and the battery also increases the weight of the entire detection instrument. In addition, due to the limited capacity of the battery, the prior art also has the risk that the detection instrument will run out of power during the detection and cannot be used normally, and the reliability of the power supply is poor.

[0004] Therefore, those skilled in the art are committed to developing an externally powered detection head that eliminates battery power supply, reduces weight, and improves power supply reliability. Utility Model Content
