Problems solved by technology

When loading and transporting, it is necessary to disassemble the lead-out part for space-saving placement. When in use, it is necessary to connect the light guide connection part to the light source device first, and then connect the lead-out part to the image processor through a cable. It is said that the connection work is more complicated, and the connection line will also block the light source device or the image processor panel
In addition, the electrical connection of the endoscope device in the past is a wired electrical connection, and the lead-out part is connected to the image processor through a cable. In order to avoid electric leakage or water ingress during cleaning, a waterproof sealing cover is required, which may reduce system safety. , it is also easy to cause the electromagnetic compatibility not to meet the standard

example 1

[0051] This example provides a connector header such as Figure 2-4 As shown, the endoscope connector head 10 is flat as a whole and has an oblong cross section. Structurally, the endoscope connector head 10 has a connector housing 100 and a receiving cavity 101 formed inside the connector housing.

[0052] The accommodating cavity 101 is formed along the connection direction (or insertion direction) of the connector head 10 and the connector base 20 . The rear end of the accommodating cavity 101 is communicated with the universal cable 13 , and the interior of the accommodating cavity 101 accommodates a plurality of connecting elements 102 extending from the universal cable 13 . These connecting elements 102 include, but are not limited to, a laser optical fiber 102d for transmitting image signals, an infrared optical fiber 102c for transmitting control and receiving signals, an illumination optical fiber 102b, and an air supply and water supply pipeline 102a.

example 2

[0067] Example 2 connector base

[0068] like Figure 3-5 As shown, this example provides a connector receptacle 20 that mates with the connector head 10 of Example 1. The connector base 20 may be provided on the light source device 2, but may not be limited thereto, for example, it may be provided on the image light source integrated machine.

[0069] The connector housing 20 mainly includes a connector housing housing 201 and a receiving cavity 202 defined by the connector housing housing 201 in structure.

[0070] The receiving cavity 202 corresponds to the connector head 10 , the cross section is an oval corresponding to the connector head 10 , and the size is just enough to accommodate the insertion of the main body of the connector head 10 .

[0071] The receiving cavity 202 accommodates a plurality of docking channels 203, each docking channel 203 accommodates a corresponding docking element 204, and each docking channel 203 corresponds to the connecting channel 103 o...

example 3

[0093] This example provides a wireless power supply system for supplying power to an endoscope. Different from the existing power supply system, the power supply system adopts a one-touch connection and does not expose any electrical connection points, so it does not need to be cleaned during cleaning. Waterproof treatment.

[0094] The power supply system includes a charging coil 106 disposed on the cavity wall of the receiving cavity 101 in the connector head 10 (see image 3 ) and the power supply coil 207 provided on the connector housing 201 (see Figure 5 ).

[0095] The charging coil 106 located in the connector head 10 is connected to the circuit board of the endoscope operating part.

[0096] Specifically, the power supply coil 207 located on the connector housing housing 201 is located at a position corresponding to the charging coil in the receiving cavity 101 . And the power supply coil 207 is electrically connected to the power supply circuit of the light sour...

Abstract

The invention discloses a connector head, a connector seat, a connection system, a light source device and an endoscope. In the connector head in this proposal, a plurality of connection elements are accommodated in a storage cavity along the connection direction, and the housing is connected with A plurality of connection channels are arranged on the opposite front surface of the connector seat, and the plurality of connection channels communicate with the receiving cavity respectively, and corresponding connection elements are arranged in each connection channel; at least one connection channel is used to cooperate with the connector seat for automatic Self-aligning structures for alignment connections. The receiving cavity in the connector seat is matched with the connector head to accommodate the insertion of the connector head; the receiving cavity accommodates a plurality of docking channels, each of which is pierced with a corresponding connecting element, and is inserted into the receiving cavity. Corresponding connection channels on the connector head are butted; at least one butt channel is a self-aligning structure that cooperates with the connector head for self-alignment connection. Accordingly, a connection system, a light source device and an endoscope are formed. This solution can realize blind insertion with high alignment accuracy.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a connector, a connector socket, a connector connection system and a light source device in the endoscope. Background technique [0002] In the past electronic endoscope, it converts the light reflected by the mucous membrane of the body cavity into an electrical signal through the charge-coupled device (CCD) installed at the tip of the endoscope, and then transmits it to the image processor through the cable, and then displays it on the display through the image processor. reproduce the image above. The use of cables to transmit images has disadvantages such as low transmission rate, large loss, and small capacity, which is not conducive to high-speed, low-loss, real-time transmission of massive data. [0003] In order to improve this shortcoming, some literatures have disclosed the application of optical communication in endoscopes to achieve high-speed real-time transmissi...
