Endoscope equipment is an important medical auxiliary device and is widely used in medical diagnosis and treatment. Endoscope equipment usually includes a PCIe interface component for connecting PCIe interface devices. The PCIe interface component is usually connected to the internal mainboard of the endoscope equipment through a PCIe interface device board. The PCIe interface device board and the internal mainboard are generally connected through gold fingers. This connection method easily makes it impossible for the PCIe interface on the PCIe interface device board to effectively connect with the internal mainboard, resulting in the isolation of the PCIe interface relative to the internal mainboard, which is easy to cause interference, so that static electricity radiation can easily interfere with the PCIe interface device board, causing the PCIe interface device board to fail, thereby causing the PCIe interface device to be disconnected or fail.

[0024] 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.

[0025] Conventional PCIe interface device boards can be directly connected to the network port connector, so they can be directly connected to the shell; however, the back shell of the medical device needs to be laid out with more interfaces and form ventilation holes, and the installation space of the back shell is limited, so the PCIe interface device board needs to be moved away from the back shell and connected to the network port connector through the transmission interface and cable. As a result, external static electricity can easily enter the PCIe interface device board through the cable and transmission interface, and because it is difficult for the conductive plug-in part and the motherboard to form an effective overlap, the conductive PCIe interface device board is isolated from the motherboard, which can easily cause interference. Static electricity radiation can easily interfere with the PCIe interface device board, causing the PCIe interface device board to fail.

[0026] According to the utility model, a medical device is provided to improve the above-mentioned problem. The medical device can be applied to any suitable device.

[0027] The following first describes the medical device in detail with reference to the accompanying drawings.

[0028] The medical device 1 provided by the utility model is combined with reference to Figures 1 to 3 The medical device 1 includes a housing 10, a mainboard 20 and an interface assembly 30. The housing 10 encloses a housing cavity 101, and the mainboard 20 is disposed in the housing cavity 101. The housing 10 has a grounding portion that is connected to the earth (the grounding portion is not shown in the figure, and it should be understood that the location of the grounding portion on the housing 10 is not limited as long as the grounding condition is met). The ground wire of the mainboard 20 is connected to the grounding portion. The interface assembly 30 includes a network port connector 31 for connecting a PCIe interface device, a PCIe interface device board 32 and a static The electrical conductive part 33 and the network port connector 31 are arranged on the shell 10; the PCIe interface device board 32 has a board body 321, a conductive plug part 322 and a transmission interface 323, the conductive plug part 322 and the transmission interface 323 are both arranged on the board body 321, the conductive plug part 322 is connected to the motherboard 20, and the transmission interface 323 is connected to the network port connector 31 through a cable 34; the electrostatic conductive part 33 is arranged on the board body 321 and has a conductive part 331, and the conductive part 331 is connected to the ground wire of the shell 10 and / or the motherboard 20.

[0029] The medical device 1 provided by the utility model is based on the setting of the electrostatic conductive part 33. The static electricity received at the network port connector 31 can be conducted to the ground through the conductive part 331 of the electrostatic conductive part 33 through the shell 10 and / or the main board 20, thereby effectively realizing the static electricity release. The PCIe interface device board 32 is not easily interfered by electrostatic radiation, which improves the anti-static interference ability of the PCIe interface device board 32. The PCIe interface device board 32 and the main board 20 are not prone to disconnection or failure, which effectively solves the electrostatic interference problem of the PCIe interface device.

[0030] When the conductive part 331 is connected to the shell 10 and the main board 20, two electrostatic discharge paths can be formed. The first electrostatic discharge path is that static electricity enters the network port connector 31, and then is transmitted to the transmission interface 323 through the cable 34, and then is conducted to the shell 10 through the conductive part 331 of the electrostatic conductive part 33, and finally is conducted to the earth through the grounding part of the shell 10; the second electrostatic discharge path is that static electricity enters the network port connector 31, and then is transmitted to the transmission interface 323 through the cable 34, and then is conducted to the main board 20 through the conductive part 331 of the electrostatic conductive part 33, and finally is conducted to the grounding part of the shell 10 through the main board 20 and then to the earth.

[0031] In one embodiment of the utility model, the transmission interface 323 on the board body 321 of the PCIe interface device board 32 is a PCIe interface. PCIe is PCI-Express (peripheral component interconnect express), which is a high-speed serial computer expansion bus standard. PCIe belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission with a high data transmission rate.

[0032] In one embodiment of the utility model, the network port connector 31 can be connected to the shell 10 by overlapping sheet metal parts or screws. Sheet metal parts are a kind of metal processing parts, which are made of metal plates such as steel plates, aluminum plates or copper plates through cutting, bending, stamping or welding to produce parts or components of various shapes and sizes.

[0033] Combined with reference Figure 1 and Figure 2 The electrostatic conductive member 33 is arranged at the end of the board body 321 close to the transmission interface 323. The electrostatic conductive member 33 is arranged close to the transmission interface 323, and the static electricity at the transmission interface 323 through the cable 34 can be quickly released, preventing static electricity from entering the effective circuit area (working area) in the board.

[0034] In one embodiment of the present invention, a connection hole is provided at the end of the plate body 321 near the transmission interface 323, and the electrostatic conductive member 33 is connected to the connection hole by fasteners such as screws. The electrostatic conductive member 33 can be made of sheet metal, which is easy to manufacture and has low cost.

[0035] Combined with reference Figure 1 and Figure 2 The conducting part 331 includes a first connecting part 3311, an intermediate connecting part 3312, and a second connecting part 3313. The first connecting part 3311 is connected to the housing 10, the second connecting part 3313 is connected to the ground line of the mainboard 20, and the intermediate connecting part 3312 is connected between the first connecting part 3311 and the second connecting part 3313. The first connecting part 3311 conducts static electricity to the ground through the grounding part of the housing 10, and the second connecting part 3313 conducts static electricity to the ground through the mainboard 20.

[0036] In one embodiment of the present utility model, Figure 1 and Figure 3 , the main board 20 is provided with an exposed copper area 22, and the second connection portion 3313 contacts the exposed copper area 22 to be connected to the ground line of the main board 20. Specifically, the second connection portion 3313 can be connected to the exposed copper area 22 by a metal fastener such as a screw, thereby enabling the second connection portion 3313 to release static electricity to the ground line of the main board 20 through the exposed copper area 22. The first connection portion 3311 is also connected to the housing 10 by a metal fastener such as a screw.

[0037] See also Figure 1 and Figure 2 The housing 10 has a bottom housing 11 and a side housing 12, the side housing 12 is connected to one side of the bottom housing 11, and the side housing 12 has a top wall 121 opposite to the bottom housing 11, and the first connection portion 3311 is connected to the top wall 121. The first connection portion 3311 is connected to the grounding portion of the housing 10 through the top wall 121. It should be understood that the housing 10 may also have a front housing, a rear housing, another side housing opposite to the side housing 12, and a top housing opposite to the bottom housing 11. Figure 1 The front shell, the other side shell and the top shell opposite to the bottom shell 11 are removed.

[0038] See also Figure 2 and Figure 3 The side of the mainboard 20 near the side shell 12 is provided with a slot 21, and the conductive plug part 322 is inserted into the slot 21, thereby realizing the connection between the PCIe interface device card 32 and the mainboard 20. The conductive plug part 322 can be inserted into the slot 21 in a gold finger manner.

[0039] Combined with reference Figure 1 and Figure 2 The board body 321 is perpendicular to the main board 20, and the first connection part 3311, the middle connection part 3312 and the second connection part 3313 are connected in sequence to form a Z shape. The first connection part 3311 and the second connection part 3313 extend from both ends of the middle connection part 3312 in two opposite directions, respectively, so as to facilitate the connection of the housing 10 and the main board 20 located in two directions, and increase the connection area between the conductive part 331 and the housing 10 and the main board 20, respectively, and increase the efficiency of electrostatic conduction.

[0040] In one embodiment of the utility model, the first connection part 3311, the middle connection part 3312 and the second connection part 3313 are connected in sequence to form a Z shape, thereby realizing three-dimensional effective overlap of the mainboard 20, the PCIe interface device board 32 and the shell 10. There will be no situation where the PCIe interface device board 32 and the mainboard 20 cannot be effectively overlapped when the PCIe interface device board 32 and the mainboard 20 are plugged in through the gold finger. The transmission interface 323 on the PCIe interface device board 32 is not isolated relative to the mainboard 20, and is not easy to cause electrostatic interference.

[0041] In one embodiment of the utility model, the height of the side shell 12 (i.e., the distance between the top wall 121 and the bottom shell 11) is equivalent to the length of the middle connecting part 3312, so that when the second connecting member is connected to the mainboard 20, the first connecting part 3311 is just overlapped on the surface of the top wall 121, corresponding to the Z-shaped structure of the first connecting part 3311, the middle connecting part 3312 and the second connecting part 3313, thereby realizing effective three-dimensional overlap of the mainboard 20, the PCIe interface device board 32 and the shell 10.

[0042] See also Figure 1 The side shell 12 is a part of the housing 10. The side shell 12 has a side wall 122 located between the top wall 121 and the bottom shell 11. The top wall 121 and the side wall 122 enclose an installation space for installing a power supply, etc. The middle connection part 3312 abuts against the side wall 122. The middle connection part 3312 is connected to the grounding part of the housing 10 through the side wall 122. Thus, the side shell 12 forms the outer shell of the power supply. The power supply can be arranged in the installation space enclosed by the top wall 121 and the side wall 122. The middle connection part 3312 of the conducting part 331 can abut against the side wall 122. The second connection part 3313 of the conducting part 331 can be connected to the copper exposed area 22 by metal fasteners such as screws, so that the second connection part 3313 is connected to the ground line of the mainboard 20.

[0043] Combined with reference Figure 1 and Figure 2 The electrostatic conductive member 33 also has a transition portion 332 connected to the board body 321, and the transition portion 332 is connected to the side of the middle connecting portion 3312 close to the board body 321. The transition portion 332 is connected to the board body 321, increasing the connection area, increasing the efficiency of electrostatic conduction, and making the connection between the transition portion 332 and the board body 321 more stable.

[0044] In one embodiment of the present utility model, Figure 1 and Figure 2 The end of the adapter part 332 close to the middle connection part 3312 is bent and extended with a folded edge 3321 in the direction away from the plate body 321. The adapter part 332 is connected to the middle connection part 3312 through the folded edge 3321, so that there is a certain space between the middle connection part 3312 and the transmission interface 323. When the transmission interface 323 is connected to the cable 34, there is a certain operating space, which is convenient for the connection operation.

[0045] Combined with reference Figure 1 and Figure 2 , the distance between the conductive plug part 322 and the transmission interface 323 is greater than the distance between the electrostatic conductive member 33 and the transmission interface 323. An effective circuit area of ​​the PCIe interface device board 32 can be formed between the conductive plug part 322 and the electrostatic conductive member 33. Compared with the conductive plug part 322, the electrostatic conductive member 33 is closer to the transmission interface 323, so that the static electricity at the transmission interface 323 can be quickly released through the electrostatic conductive member 33, reducing the static electricity radiation to the conductive plug part 322.

[0046] In one embodiment of the present invention, the transmission interface 323 is disposed at one end of the board body 321 , so that the transmission interface 323 is adjacent to the electrostatic conductive member 33 , and static electricity at the transmission interface 323 can be released more quickly through the electrostatic conductive member 33 .
