Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and in particular to a connector, an endoscope, an endoscope adapter and an endoscope system. Background Art

[0002] With the development of science and technology, endoscope system has become one of the important tools in the medical field. Endoscope system mainly includes endoscope and endoscope adapter. Endoscope adapter can include light source device and processing device. Endoscope is generally connected to endoscope adapter through connector to realize communication with endoscope adapter.

[0003] In existing endoscope systems, the endoscope is mainly connected to the endoscope adapter by means of electrical connection. This may corrode the metal contacts on the endoscope used for electrical connection when the endoscope is decontaminated. Therefore, some existing endoscope systems use a non-electrical connection method to connect the endoscope to the endoscope adapter. Usually, these endoscope systems use infrared communication to realize the communication of control signals between the endoscope and the endoscope adapter.

[0004] However, in an existing endoscope system in which the endoscope is not electrically connected to an endoscope adapter device, for the connector on the endoscope, if only one infrared transceiver device is used on the connector to realize infrared communication, only half-duplex communication can be realized. Half-duplex communication not only has high latency but also has very low communication efficiency. If at least two infrared transceiver devices are used to realize infrared communication, crosstalk between the transceiver signals of multiple infrared communication devices will occur, resulting in very poor communication quality.

DETAILED DESCRIPTION

[0029] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0030] According to one aspect of the present invention, see Figure 1 and Figure 2 , a connector 100 is provided. The connector 100 can be applied to an endoscope 10. Therefore, according to another aspect of the utility model, an endoscope 10 is provided, and the endoscope 10 may include any of the connectors 100 to be introduced below. The endoscope 10 can be applied to an endoscope system, and a typical endoscope system may include the endoscope 10 and an endoscope adapter 20. Therefore, according to another aspect of the utility model, an endoscope adapter 20 is provided, and, according to another aspect of the utility model, an endoscope system is provided. The endoscope adapter 20 may be Figure 1The light source device 260 shown in the figure is either the processing device 270 or an integrated device in which the light source device and the processing device are integrated. The endoscope 10 can be electrically connected to the endoscope adapter device 20 via the connector 100 .

[0031] See also Figure 3 , Figure 4 and Figure 5 The connector 100 may include a first circuit board 110 and a first housing 120. The first circuit board 110 may be a printed circuit board. The first housing 120 may protect the first circuit board 110. Two first annular walls 123 may be provided on the first housing 120. The first annular walls 123 may be formed integrally on the first housing 120, or may be separately processed from the first housing 120 and connected together by welding, clamping or threading. The first circuit board 110 and the two first annular walls 123 may respectively enclose a first installation cavity 140 and a second installation cavity 150 spaced from each other. One end of the first annular wall 123 may be connected to the first housing 120, and the other end may be abutted against the first circuit board 110, or may be connected to the first circuit board 110 by clamping or threading. The first annular wall 123 may be a separation plate of various forms, or may be formed by combining any number of separation plates. At least the two opposite side walls of the two first annular walls 123 can be used to block infrared communication. The first installation cavity 140 and the second installation cavity 150 mentioned here are spaced apart from each other, which means that the first installation cavity 140 cannot perform infrared communication with the second installation cavity 150. As long as the first installation cavity 140 and the second installation cavity 150 can be spaced apart, the present application does not limit the specific form of the first annular wall 123, which can be an annular wall with a cross-section in various shapes such as a circular ring, a square or a diamond, the cross-sections of the two first annular walls 123 can be the same or different, and the first installation cavity 140 and the second installation cavity 150 can be cavities of any form.

[0032] The first circuit board 110 may be provided with a first infrared receiver 111 and a first infrared transmitter 112, and the first infrared receiver 111 may be completely contained in the first mounting cavity 140, and the first infrared transmitter 112 may be completely contained in the second mounting cavity 150. Complete containment means that, on the basis that the first mounting cavity 140 and the second mounting cavity 150 are spaced apart from each other, infrared communication does not occur between the first infrared receiver 111 and the first infrared transmitter 112, that is, signal crosstalk between the first infrared receiver 111 and the first infrared transmitter 112 can be avoided. The first infrared receiver 111 and the first infrared transmitter 112 may be infrared communication devices of any form, wherein the first infrared receiver 111 can receive external infrared communication signals, and the first infrared transmitter 112 can transmit infrared communication signals. The first housing 120 may be provided with a first slot 121 and a second slot 122, and the first mounting cavity 140 may be communicated with the outside through the first slot 121, and the second mounting cavity 150 may be communicated with the outside through the second slot 122. The first infrared receiver 111 located in the first installation cavity 140 can receive external infrared communication signals through the first groove 121 , and the first infrared transmitter 112 located in the second installation cavity 150 can transmit infrared communication signals to the outside through the second groove 122 .

[0033] In such a connector 100, the first infrared receiver 111 is arranged in the first mounting cavity 140, and the first infrared transmitter 112 is arranged in the second mounting cavity 150. In addition, due to the presence of at least a portion of the first annular wall 123 that blocks infrared communication, the first mounting cavity 140 and the second mounting cavity 150 are separated. The first infrared receiver 111 in the first mounting cavity 140 will not cause signal crosstalk with the first infrared transmitter 112 in the second mounting cavity 150. For example, the infrared signal emitted by the first infrared transmitter 112 will not be erroneously received by the first infrared receiver 111.

[0034] The connector 100 provided in the present application can realize non-electrical connection with an external adapter device through the first infrared receiver 111 and the first infrared transmitter 112. The connector 100 is applied to the endoscope 10 to avoid the problem of unreliable signal connection caused by the influence of disinfection, etc. Moreover, such a connector 100 can realize full-duplex communication with an external adapter device through the first infrared receiver 111 and the first infrared transmitter 112, and the communication efficiency is higher. In the process of full-duplex communication between the connector 100 and the external adapter device, the setting of the first annular wall 123 can prevent signal crosstalk between the first infrared receiver 111 and the first infrared transmitter 112, thereby improving the communication quality of full-duplex communication.

[0035] In one embodiment of the present invention, see Figure 3 and Figure 5 The connector 100 may include a first lens 160, which may be connected to the first housing 120 and cover the first groove 121. The first lens 160 may be made of any form of light-transmitting material, and the first lens 160 covers the first groove 121, which may prevent the first infrared receiver 111 from falling from the first groove 121, and the first lens 160 may protect the first infrared receiver 111 from the external environment. The transmittance of the first lens 160 to infrared light may be not less than 10%, and preferably, the transmittance of the first lens 160 to infrared light may be not less than 80%.

[0036] The first lens 160 may include a first light-transmitting portion 161 and a first position-limiting portion 162. The first light-transmitting portion 161 may block the first groove 121. The first position-limiting portion 162 may be located in the first mounting cavity 140. The projection of the first position-limiting portion 162 on the plane where the first circuit board 110 is located may be larger than the projection of the first groove 121 on the plane where the first circuit board 110 is located. The first position-limiting portion 162 may prevent the first lens 160 from falling off from the first groove 121 to the outside.

[0037] In one embodiment of the present invention, see Figure 3 and Figure 5 The connector 100 may include a second lens 170, which may be connected to the first housing 120, and the second lens 170 may cover the second groove 122. The second lens 170 may be made of any form of light-transmitting material, and the second lens 170 covers the second groove 122, which may prevent the first infrared emitter 112 from falling from the second groove 122, and the second lens 170 may protect the first infrared emitter 112 from being affected by the external environment. The transmittance of the second lens 170 to infrared light may be not less than 10%, and preferably, the transmittance of the second lens 170 to infrared light may be not less than 80%.

[0038] The second lens 170 may include a second light-transmitting portion 171 and a second position-limiting portion 172, the second light-transmitting portion 171 may block the second groove 122, the second position-limiting portion 172 may be located in the second mounting cavity 150, and the projection of the second position-limiting portion 172 on the plane where the first circuit board 110 is located may be larger than the projection of the second groove 122 on the plane where the first circuit board 110 is located. The second position-limiting portion 172 may prevent the second lens 170 from falling off from the second groove 122 to the outside.

[0039] like Figure 3 and Figure 5In the illustrated embodiment, the connector 100 is provided with a first lens 160 and a second lens 170, and the first lens 160 includes a first light-transmitting portion 161 and a first position-limiting portion 162, and the second lens 170 includes a second light-transmitting portion 171 and a second position-limiting portion 172. In other embodiments not illustrated, the connector 100 may be provided with only the first lens 160 without the second lens 170, and similarly, the connector 100 may be provided with only the second lens 170 without the first lens 160.

[0040] In one embodiment of the present invention, see Figure 3 , the spacing between the first groove 121 and the second groove 122 (the spacing A shown in the figure) may be not less than 2 mm. When the connector 100 is applied to an endoscope, when the endoscope communicates with an endoscope adapter through the connector 100, the endoscope and the endoscope adapter are usually very close to each other, wherein the connector 100 can communicate with the endoscope adapter at a very close distance. When the spacing between the first groove 121 and the second groove 122 is not less than 2 mm, it can be ensured that there will be no signal crosstalk between the first infrared receiver 111 in the first installation cavity 140 and the first infrared transmitter 112 in the second installation cavity 150, and the first infrared receiver 111 will not mistakenly receive the infrared signal emitted by the first infrared transmitter 112.

[0041] Among common infrared communication devices, some infrared communication devices have both a part capable of receiving infrared signals and a part capable of transmitting infrared signals. Figure 3, the first infrared receiver 111 may include a first receiving end 1111 and a first transmitting end 1112, and the first infrared transmitter 112 may include a second receiving end 1121 and a second transmitting end 1122, wherein the first receiving end 1111 is turned on and the first transmitting end 1112 is turned off, and the second receiving end 1121 is turned off and the second transmitting end 1122 is turned on. The first receiving end 1111 of the first infrared receiver 111 may receive infrared signals, and the first transmitting end 1112 of the first infrared receiver 111 may transmit infrared signals, therefore, when the first infrared receiver 111 is used to receive infrared signals, the first receiving end 1111 is turned on and the first transmitting end 1112 is turned off. The second receiving end 1121 of the first infrared transmitter 112 may receive infrared signals, and the second transmitting end 1122 of the first infrared transmitter 112 may transmit infrared signals, therefore, when the first infrared transmitter 112 is used to transmit infrared signals, the second receiving end 1121 is turned off and the second transmitting end 1122 is turned on. During the use of the connector 100, if the first receiving end 1111 or the second transmitting end 1122 is damaged, the first receiving end 1111 can be turned off and the first transmitting end 1112 can be turned on, and the second receiving end 1121 can be turned on and the second transmitting end 1122 can be turned off. At this time, the first infrared receiver 111 can transmit infrared signals, and the first infrared transmitter 112 can receive infrared signals, and the connector 100 can continue to be used. Such a connector 100 can have a longer service life.

[0042] In an embodiment of the present invention, the first receiving end 1111, the first transmitting end 1112, the second receiving end 1121 and the second transmitting end 1122 may be located at four corners respectively, wherein the first receiving end 1111 and the second transmitting end 1122 may be located at different sides. That the first receiving terminal 1111, the first transmitting terminal 1112, the second receiving terminal 1121 and the second transmitting terminal 1122 can be located at the four corners respectively means that the first receiving terminal 1111, the first transmitting terminal 1112, the second receiving terminal 1121 and the second transmitting terminal 1122 can be used as four vertices, and the four vertices can form a quadrilateral. The first receiving terminal 1111, the first transmitting terminal 1112, the second receiving terminal 1121 and the second transmitting terminal 1122 can be located at the four corners of the quadrilateral respectively. At the same time, since the first receiving terminal 1111 and the second transmitting terminal 1122 can be located on different sides, it can be considered that the first receiving terminal 1111 and the second transmitting terminal 1122 are located on the diagonal line. In this way, the distance between the first receiving terminal 1111 and the second transmitting terminal 1122 can be farther, and signal crosstalk between the first receiving terminal 1111 and the second transmitting terminal 1122 can be further avoided.

[0043] In one embodiment of the present invention, the first housing 120 can block infrared communication. The first housing 120 can be made entirely of a material that can block infrared communication. In such a connector 100, signal crosstalk between the first infrared receiver 111 and the first infrared transmitter 112 can be prevented more stably.

[0044] The endoscope 10 provided by the present invention may include any one of the connectors 100 described above.

[0045] The endoscope adapter device 20 provided by the utility model, see Figure 5 The endoscope adapter 20 can be used to adapt to the endoscope 10 described above. The endoscope adapter 20 may include a second circuit board 210 and a second housing 220, and two second annular walls 223 may be provided on the second housing 220. The second circuit board 210 may be a printed circuit board. The second housing 220 may protect the second circuit board 210. The second annular wall 223 may be formed integrally on the second housing 220, or may be connected to the second housing 220 by welding, clamping or threading after being processed separately. The second circuit board 210 and the two second annular walls 223 may respectively enclose a third installation cavity 240 and a fourth installation cavity 250 spaced from each other. One end of the second annular wall 223 is connected to the second housing 220, and the other end may be abutted against the second circuit board 210, or may be connected to the second circuit board 210 by clamping or threading. The second annular wall 223 may be a separation plate of various forms, or may be formed by combining any number of separation plates. At least the two opposite side walls of the two second annular walls 223 can be used to block infrared communication. Here, the third installation cavity 240 and the fourth installation cavity 250 are spaced apart from each other, which means that the third installation cavity 240 cannot perform infrared communication with the fourth installation cavity 250. As long as the third installation cavity 240 and the fourth installation cavity 250 can be spaced apart, the specific form of the second annular wall 223 is not limited in this application. The third installation cavity 240 and the fourth installation cavity 250 can be cavities of any form.

[0046] The second circuit board 210 may be provided with a second infrared receiver 211 and a second infrared transmitter 212. The second infrared receiver 211 may be used to receive the infrared signal transmitted by the first infrared transmitter 112, and the second infrared transmitter 212 may be used to transmit the infrared signal to the first infrared receiver 111. The second infrared receiver 211 may be completely accommodated in the third mounting cavity 240, and the second infrared transmitter 212 may be completely accommodated in the fourth mounting cavity 250. The meaning of complete accommodation is that, on the basis of the third mounting cavity 240 and the fourth mounting cavity 250 being spaced apart from each other, infrared communication will not occur between the second infrared receiver 211 and the second infrared transmitter 212, that is, signal crosstalk between the second infrared receiver 211 and the second infrared transmitter 212 may be avoided. The second housing 220 may be provided with a third slot 221 and a fourth slot 222. The third mounting cavity 240 may be communicated with the outside through the third slot 221, and the fourth mounting cavity 250 may be communicated with the outside through the fourth slot 222. The infrared communication signal emitted by the second infrared transmitter 212 can reach the first slot 121 through the fourth slot 222, and reach the first infrared receiver 111 through the first slot 121 and be received by the first infrared receiver 111; the infrared communication signal emitted by the first infrared transmitter 112 can reach the third slot 221 through the second slot 122, and reach the second infrared receiver 211 through the third slot 221 and be received by the second infrared receiver 211.

[0047] Such an endoscope adapter device 20 can achieve full-duplex infrared communication with the endoscope 10 , and no infrared signal crosstalk will occur between the second infrared receiver 211 and the second infrared transmitter 212 .

[0048] The endoscope system provided by the utility model refers to Figure 1 and Figure 5 The endoscope system may include the endoscope 10 as described above and the endoscope adapter 20 as described above. In such an endoscope system, full-duplex infrared communication can be achieved between the endoscope 10 and the endoscope adapter 20, the communication efficiency is high, and there is no signal crosstalk between the first infrared receiver 111 and the first infrared transmitter 112, and there is no signal crosstalk between the second infrared receiver 211 and the second infrared transmitter 212, the communication quality is high, and the full-duplex infrared communication between the endoscope 10 and the endoscope adapter 20 is more stable.

[0049] See also Figure 5When the endoscope adapter 20 is adapted to the endoscope 10, the distance between the first shell 120 and the second shell 220 (shown as distance B) may be no greater than 0.3 mm. The distance between the first shell 120 and the second shell 220 is no greater than 0.3 mm, which can prevent the first infrared receiver 111 from receiving the infrared signal emitted by the second infrared transmitter 212, and can prevent the infrared signal emitted by the first infrared transmitter 112 from reaching the second infrared receiver 211, further preventing infrared signal crosstalk, and the endoscope system can be more stable when in use.
