In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element. "A plurality" means greater than or equal to two.

[0028] The present invention provides a composite connector 101 and an endoscope detection device, referring to Figure 1 The composite connector 101 is used to connect with the connector 102. The composite connector 101 and the connector 102 can be simply understood as interconnected male and female plugs. Among them, one of the composite connector 101 and the connector 102 is used to connect to the host, and the other is used to connect to the endoscope. In other words, the composite connector 101 can be connected to the endoscope and the connector 102 to the host; or the composite connector 101 can be connected to the host and the connector 102 to the endoscope. It is not limited to which of the endoscope and the host the composite connector 101 is connected to, as long as the endoscope and the host can be connected through the composite connector 101 and the connector 102.

[0029] Reference Figure 1 and Figure 2The composite connector 101 provided in an embodiment of the present invention includes a housing 1, an optical signal transmission element 2, and a circuit board 3. The optical signal transmission element 2 is used to transmit at least the detection signal of the endoscope's pressure sensor. The housing 1 includes a housing cavity 10, within which both the optical signal transmission element 2 and the circuit board 3 are mounted. The circuit board 3 is spaced from the optical signal transmission element 2, i.e., there is a gap between the circuit board 3 and the optical signal transmission element 2, but no contact connection. This means that the electrical signal transmission path and the optical signal transmission path run independently and in parallel within the composite connector 101. The circuit board 3 does not require an integrated optical signal processing unit, which helps reduce the size and simplify the structure of the circuit board 3. The housing 1 includes a first socket 131 and a second socket 132. The first socket 131 is disposed opposite the optical signal transmission element 2, and the second socket 132 is disposed opposite the circuit board 3. When the composite connector 101 is connected to the connector 102, the connector 102 is connected to the optical signal transmission element 2 via the first socket 131 and to the circuit board 3 via the second socket 132. This arrangement integrates the optical signal transmission interface and the electrical signal transmission interface into one composite connector 101, which means that only one connector is needed to realize the transmission of two optical signals and electrical signals, without the need for additional plugs and / or cables to transmit optical signals, and the structure is simple; and a single plug-in operation can realize the docking of the optical signal transmission path and the electrical signal transmission path, reducing the operational difficulty of connecting the host and the endoscope.

[0030] It should be noted that the above-mentioned optical signal transmission component 2 can be a fiber optic connector or an optical fiber. This application does not limit the specific structure of the optical signal transmission component 2, as long as the optical signal transmission component 2 can transmit the detection signal fed back by the pressure sensor.

[0031] An embodiment of the present utility model provides a composite connector 101, which is used to connect with a connector 102. One of the composite connector 101 and the connector 102 is used to connect to a host, and the other is used to connect to an endoscope. The composite connector 101 includes a shell 1, an optical signal transmission component 2 and a circuit board 3. The shell 1 is provided with a housing 10. The shell 1 is provided with a first socket 131 and a second socket 132. The optical signal transmission component 2 is used to transmit at least the detection signal of the pressure sensor of the endoscope; the optical signal transmission component 2 and the circuit board 3 are both arranged in the housing 10, and the circuit board 3 is spaced apart from the optical signal transmission component 2. The first socket 131 is arranged opposite to the optical signal transmission component 2, and the second socket 132 is arranged opposite to the circuit board 3. When the composite connector 101 is connected to the connector 102, the endoscope is electrically connected to the host to transmit the detection signal to the host. This arrangement enables the optical signal transmission interface and the electrical signal transmission interface to be integrated into one composite connector 101, and the docking of the two transmission paths can be achieved with one plug-in operation, which simplifies the operational difficulty of connecting the host and the endoscope and improves the convenience of connection; and only one connector is used to realize the transmission of two signals, without the need for additional plugs and / or cables to transmit optical signals, and the circuit board 3 does not need to integrate an optical signal processing unit, making the structure of the composite connector 101 relatively simple and the design ingenious.

[0032] In some embodiments, reference Figure 2 The housing 1 includes an upper shell 11, a lower shell 12 and a front shell 13 which together form a housing cavity 10. The housing cavity 10 is composed of a plurality of components, which helps to reduce the difficulty of assembling the optical signal transmission component 2 and the circuit board 3 in the housing cavity 10. The upper shell 11 and the lower shell 12 are connected in a matched manner, that is, the upper shell 11 and the lower shell 12 are arranged as relative half-shell structures. The same end of the matched upper shell 11 and the lower shell 12 (the left end of the upper shell 11 and the lower shell 12) is detachably connected to the front shell 13, and the first socket 131 and the second socket 132 are arranged through the front shell 13, that is, the first socket 131 and the second socket 132 are adjacently formed at the end of the front shell 13 away from the upper shell 11 and the lower shell 12, then correspondingly, referring to Figure 1 The two plugs on connector 102 are also arranged adjacently at the same end, which helps reduce the size of connector 102 and composite connector 101, resulting in a more compact design for connector 102 and composite connector 101. When plugging connector 102 into composite connector 101, there is no need to plug first socket 131 and second socket 132 separately on different planes. Connector 102 can be plugged into both first and second sockets 131 and 132 in a single operation, facilitating plugging connector 102 into composite connector 101.

[0033] In some embodiments, reference Figure 2The composite connector 101 further includes a bracket 4 disposed within the accommodating cavity 10. One of the optical signal transmission component 2 and the circuit board 3 is disposed between the bracket 4 and the upper shell 11, and the other of the optical signal transmission component 2 and the circuit board 3 is disposed between the bracket 4 and the lower shell 12. Alternatively, the optical signal transmission component 2 may be disposed between the bracket 4 and the upper shell 11, and the circuit board 3 may be disposed between the bracket 4 and the lower shell 12; or the circuit board 3 may be disposed between the bracket 4 and the upper shell 11, and the optical signal transmission component 2 may be disposed between the bracket 4 and the lower shell 12. Regardless of which of the aforementioned embodiments is used, the bracket 4, after mating with the upper shell 11 and the lower shell 12, can fix the optical signal transmission component 2 and the circuit board 3, thereby limiting the positions of the optical signal transmission component 2 and the circuit board 3 within the accommodating cavity 10, so that the optical signal transmission component 2 is stably located relative to the first socket 131, and the circuit board 3 is stably located relative to the second socket 132, thereby maintaining the transmission stability of the two signals.

[0034] In some embodiments, reference Figure 2 and Figure 3 The optical signal transmission component 2 is set between the bracket 4 and the upper shell 11, and the bracket 4 includes a main body 41 and a first limiting structure 42. The first limiting structure 42 is set on the side of the main body 41 facing the upper shell 11 (the top surface of the main body 41). The optical signal transmission component 2 is fixed to the main body 41 through the first limiting structure 42, so that the optical signal transmission component 2 can be detachably installed on the top surface of the main body 41, reducing the difficulty of assembling the optical signal transmission component 2 and the bracket 4.

[0035] Specifically, the first limiting structure 42 can be a limiting groove and / or a fixing buckle. In the embodiment shown in the schematic diagram of the present application, referring to Figure 2 and Figure 3 The first limiting structure 42 is a limiting groove that is basically formed according to the outer contour shape of the optical signal transmission component 2. The optical signal transmission component 2 is installed in the limiting groove to limit the freedom of translation of the optical signal transmission component 2 relative to the main body 41, so as to facilitate the reliable connection between the optical signal transmission component 2 and the connector and stably transmit the detection signal.

[0036] In some embodiments, reference Figure 2 and Figure 3 The bracket 4 further includes a second retaining structure 43, which is disposed on a side of the body 41 facing the upper housing 11. Specifically, the first retaining structure 42 and the second retaining structure 43 are disposed adjacent to each other, and the optical signal transmission component 2 is retained within the first retaining structure 42 and the second retaining structure 43. The first retaining structure 42 and the second retaining structure 43 cooperate to secure the optical signal transmission component 2, effectively retaining the optical signal transmission component 2 in a position relative to the first socket 131.

[0037] Specifically, the second limiting structure 43 can also be a limiting groove and / or a fixing buckle. In the embodiment shown in the schematic diagram of the present application, refer to Figure 2 and Figure 3 The second limiting structure 43 is a fixed buckle, and the optical signal transmission component 2 is abutted between the second limiting structure 43 and the main body 41. The second limiting structure 43 limits the freedom of the optical signal transmission component 2 to separate from the main body 41, further improving the stability of the optical signal transmission component 2 in transmitting the detection signal.

[0038] In some embodiments, reference Figure 2 and Figure 4 The circuit board 3 is arranged between the bracket 4 and the lower shell 12. The bracket 4 also includes a third limiting structure 44 connected to the side of the body 41 facing the lower shell 12 (the bottom surface of the body 41). The circuit board 3 is fixed to the body 41 and / or the lower shell 12 through the third limiting structure 44, so that the circuit board 3 can be detachably installed between the body 41 and the lower shell 12, reducing the difficulty of fixing and assembling the circuit board 3 and the bracket 4.

[0039] Specifically, refer to Figure 2 and Figure 4 The third limiting structure 44 may be a rib and / or a slot. For example, the third limiting structure 44 may be configured as a protruding rib and abut against the side of the circuit board 3 facing the body 41 (the top surface of the circuit board 3). The lower shell 12 may also be provided with a protruding rib and correspondingly abut against the side of the circuit board 3 facing away from the body 41 (the bottom surface of the circuit board 3), so that the circuit board 3 is fixed between the body 41 and the lower shell 12. Alternatively, the third limiting structure 44 may be configured as a slot surrounding the circuit board 3 to clamp the circuit board 3 to the bottom surface of the body 41. Alternatively, the third limiting structure 44 may be configured as a protruding rib, and the lower shell 12 may be provided with a slot surrounding the circuit board 3. The third limiting structure 44 presses the circuit board 3 into the slot in the lower shell 12, so that the circuit board 3 is fixed to the lower shell 12. The present application does not limit the specific structure of the third limiting structure 44, as long as the third limiting structure 44 can limit the relative position of the circuit board 3 in the accommodating cavity 10.

[0040] In some embodiments, reference Figure 5 and Figure 6The fourth limiting structure 121 is arranged on the lower shell 12, and the circuit board 3 is fixed between the third limiting structure 44 and the fourth limiting structure 121; wherein the circuit board 3 is provided with a slot 31 matched with the fourth limiting structure 121, that is, the fourth limiting structure 121 is arranged as a rib and abuts against the bottom surface of the circuit board 3, and the circuit board 3 is fixed between the third limiting structure 44 and the fourth limiting structure 121, so that the third limiting structure 44 is also arranged as a rib and abuts against the top surface of the circuit board 3 to limit the freedom of the circuit board 3 from the bracket 4 and the lower shell 12. In addition, after the circuit board 3 is inserted with the fourth limiting structure 121 through the slot 31, the freedom of the circuit board 3 from the bracket 4 and the lower shell 12 is limited, the circuit board 3 is stably installed in the position opposite to the second socket in the accommodating cavity, and the stability of the circuit board 3 in transmitting an electric signal is improved.

[0041] In some embodiments, referring to Figure 4 and Figure 5 The lower shell 12 is provided with a first positioning part 122, the bracket 4 is provided with a second positioning part 45 matched with the first positioning part 122, and the first positioning part 122 is connected with the second positioning part 45, so that the bracket 4 is detachably installed in the lower shell 12. In this way, while the bracket 4 and the lower shell 12 are fixed through the first positioning part 122 and the second positioning part 45, the relative positions of the optical signal transmission member 2 and the circuit board 3 installed on the bracket 4 are also limited, and the positions of the bracket 4, the optical signal transmission member 2 and the circuit board 3 are fixed at one time, so that the structure is simple and easy to implement. Figure 2

[0042] Specifically, referring to Figure 4 and Figure 5 The first positioning part 122 can be one of a plug and a slot, and the second positioning part 45 can be the other one of the plug and the slot. In the embodiment shown in the schematic diagram of the application, the first positioning part 122 is arranged as a slot 31, and the second positioning part 45 is arranged as a plug.

[0043] In some embodiments, referring to Figure 2 The composite connector 101 further comprises a wire 5 for transmitting a detection signal, and one end of the wire 5 is electrically connected with the optical signal transmission member 2 and the circuit board 3, that is, the pressure signal transmission path and the electric signal transmission path are integrated in the wire 5 in the embodiment of the application, the transmission of the two kinds of signals is realized integrally through the wire 5, and a plurality of wires 5 need not to be additionally arranged, so that the structure of the composite connector 101 is further simplified.

[0044] Specifically, referring to Figure 2 ​The wire 5 can extend into the housing 1 to connect the optical signal transmission element 2 and the circuit board 3, or a component can extend from the housing 1 to connect the wire 5 outside the accommodating cavity 10. In the embodiment shown in the schematic diagram of the present application, the wire 5 passes through the housing 1, and the upper shell 11 and the lower shell 12 jointly form a groove for passing the wire 5. There is no need to set up additional components to extend outside the accommodating cavity 10 to connect the wire 5, which reduces the difficulty of structural setting of the composite connector 101 and also reduces the difficulty of assembling the wire 5.

[0045] In some embodiments, reference Figure 2 The housing 1 further includes a rear shell 14, in which the wires 5 are clamped. The rear shell 14 is detachably connected to the ends of the upper shell 11 and the lower shell 12 away from the front shell 13. In other words, the upper shell 11 and the lower shell 12 are clamped between the front shell 13 and the rear shell 14, and the opposite ends of the upper shell 11 and the lower shell 12 are respectively fixed by the front shell 13 and the rear shell 14, thereby improving the assembly stability of the upper shell 11 and the lower shell 12 after they are aligned. In addition, the rear shell 14 connects the upper shell 11 and the lower shell 12 while simultaneously fixing the wires 5. This simplifies the assembly process and facilitates the assembly of the composite connector 101.

[0046] The present invention also provides an endoscope detection device according to the embodiment of the present invention. Figure 1 The endoscopic detection device includes an endoscope (not shown in the figure), a host (not shown in the figure) and the above-mentioned composite connector 101. As can be seen from the above, one of the composite connector 101 and the connector 102 is connected to the host, and the other is connected to the endoscope. By configuring the above-mentioned composite connector 101, it is convenient to plug the composite connector 101 and the connector 102, and the connection between the endoscope and the host can be achieved in one operation, which is convenient for medical staff to operate.

[0047] For ease of explanation, refer to Figure 1 , taking the example of the composite connector 101 being connected to the host, the connector 102 being connected to the endoscope, and the endoscope being used to detect the patient's intrarenal pressure, to explain the signal transmission principle of the composite connector 101: one end of the endoscope for insertion has a pressure sensor for detecting the pressure in the patient's body, and the other end of the endoscope has a connector 102; one end of the composite connector 101 is connected to the host, and the other end of the composite connector 101 is connected to the connector 102 to transmit the detection signal of the pressure sensor to the host, and then, after the detection signal is processed by the optical signal processing unit and the data processing unit in the host, the detection signal is displayed in real time in the form of an image on the screen of the host, so that medical staff can monitor the patient's intrarenal pressure value and high pressure duration, thereby reducing the incidence of postoperative complications.
