[0030] Example 1

[0031] The utility model provides an endoscope operating assembly, which is used for an operator to hold so as to facilitate operations under the endoscope. Figures 1 to 4 As shown, the endoscope operating assembly includes: a main housing 100, a pressing member 300 and a lining plate 400. The main housing 100 is an internal hollow structure to form a receiving cavity, which is used to receive various circuit boards and provide wiring space. The pressing member 300 is arranged on the main housing 100 through the lining plate 400. Specifically, the lining plate 400 is detachably arranged on the main housing 100 and is pressed above the pressing member 300.

[0032] like Figures 5 to 7 As shown, the pressing member 300 at least includes a button portion 310, and the backing plate 400 is provided with a first through hole 410 for the button portion 310 to pass through so that the button portion 310 is exposed outside the backing plate 400. The pressing member 300 is made of a flexible material, such as silicone, soft rubber, etc., so that the pressing member 300 has good deformation ability and touch.

[0033] The main housing 100 is the main part of the outer peripheral surface of the endoscope operating assembly, and the lining plate 400 is a part of the outer peripheral surface of the endoscope operating assembly. The lining plate 400 and the main housing 100 are together formed to form the outer peripheral surface of the endoscope operating assembly, and the outer peripheral surface refers to a non-end surface.

[0034] The lining plate 400 and the main housing 100 are made of metal material, and a cable 120 is provided at the rear end of the main housing 100, and the cable 120 is connected to a grounded camera host (not shown). When the operator holds the endoscope operating assembly, the static electricity on the operator's hand can be transmitted to the cable 120 through the metal main housing 100, and then transmitted to the camera host by the cable 120, thereby eliminating the static electricity.

[0035] When the operator's hand touches the button part 310, the hand will contact the lining plate 400, and part of the static electricity on the hand will be transferred to the metal lining plate 400. In order to smoothly transfer the static electricity on the lining plate 400 to the main housing 100, in this embodiment, a recessed area 111 is provided on one of the main housing 100 and the lining plate 400, and a convex part 420 is provided on the other, and the recessed area 111 cooperates with the convex part 420. The recessed area 111 can be understood as a groove body, and the convex part 420 can be understood as a block body.

[0036] When the lining plate 400 is in poor contact with the main housing 100, the static electricity on the lining plate 400 cannot be eliminated, and the static electricity will gradually accumulate on the lining plate 400, posing a safety hazard. In this embodiment, by providing the convex portion 420 and the concave area 111, the contact area between the lining plate 400 and the main housing 100 can be effectively increased, and the contact stability between the lining plate 400 and the main housing 100 is improved, which is conducive to conducting the static electricity on the lining plate 400 to the main housing 100, and can effectively avoid the problem that the static electricity on the lining plate 400 cannot be conducted to the main housing 100 due to the poor contact between the lining plate 400 and the main housing 100.

[0037] In one embodiment, the recessed area 111 is provided on the main housing 100, and the convex portion 420 is provided on the lining plate 400. Specifically, the main housing 100 is provided with the recessed area 111 recessed inwardly, and the recessed area 111 and the convex portion 420 form a surface contact fit.

[0038] The recessed area 111 is formed with an opening on the outer peripheral surface of the main housing 100, and the recessed area 111 has a groove bottom opposite to the opening. The convex portion 420 contacts at least one of the side wall and the groove bottom of the recessed area 111, wherein the side wall of the recessed area 111 extends from the opening to the groove bottom, and the side wall of the recessed area 111 can be a cylindrical surface, a conical surface, or a surface of other shapes.

[0039] The protrusions 420 are distributed near the edge of the lining plate 400. The protrusions 420 can be in the shape of a full ring or a non-full ring. When the protrusions 420 are in the shape of a non-full ring, the protrusions 420 are distributed at intervals. In one embodiment, the lining plate 400 is in the shape of a quadrilateral, and the protrusions 420 are distributed at the four corners of the lining plate 400.

[0040] There are two situations in which the positional relationship between the lining plate 400 and the recessed area 111 exists. Figure 1 In the first case, the liner 400 is accommodated in the recessed area 111, and the area of ​​the liner 400 is substantially equal to the area of ​​the recessed area 111. In the second case, the liner 400 is not accommodated in the recessed area 111, and only the convex portion 420 is located in the recessed area 111, and the size of the recessed area 111 is substantially equal to the size of the convex portion 420. It should be noted that in this specification, "substantially" or "basically" can be understood as close to, approximately, or within a predetermined range from a target value.

[0041] The pressing member 300 further includes a base sheet 320 provided with the above-mentioned button portion 310, and the button portion 310 and the base sheet 320 are integrally formed. The base sheet 320 is accommodated in the recessed area 111, and the convex portion 420 is located at the periphery of the base sheet 320. In this embodiment, the lining plate 400 is accommodated in the recessed area 111, and the sum of the area of ​​the surface of the base sheet 320 facing the groove bottom of the recessed area 111 and the area of ​​the surface of the convex portion 420 facing the groove bottom of the recessed area 111 is equal to the area of ​​the groove bottom of the recessed area 111. Under the above-mentioned setting mode, the position between the base sheet 320 and the convex portion 420 is fixed, and there will be no positional deviation after installation, which improves the installation accuracy to a certain extent.

[0042] like Figure 4 As shown, a switch circuit board assembly 200 is provided on the main housing 100, and a pressing member 300 cooperates with the switch circuit board assembly 200. The switch circuit board assembly 200 includes a switch circuit board 210 and a switch 220 provided on the switch circuit board 210, and a button portion 310 cooperates with the switch 220. There can be multiple button portions 310 and switches 220, and multiple button portions 310 and multiple switches 220 are arranged one by one. The switch 220 can be a push switch or a toggle switch. Preferably, the switch 220 is a push switch.

[0043] The switch circuit board assembly 200 can be arranged inside the main housing 100 or outside the main housing 100. In order to protect the switch circuit board assembly 200 and avoid the influence of the external environment on it, preferably, the switch circuit board assembly 200 is accommodated in the main housing 100. The main housing 100 is provided with a second through hole 112 for the switch 220 to pass through. After the switch 220 passes through the second through hole 112, it abuts against the button part 310. When the lining plate 400 is accommodated in the recessed area 111, the second through hole 112 is formed at the bottom of the groove of the recessed area 111; when the lining plate 400 is not accommodated in the recessed area 111, the second through hole 112 is formed on the shell wall of the main housing 100.

[0044] like Figure 2 and Figure 4As shown, the switch circuit board assembly 200, the pressing member 300 and the lining plate 400 are arranged on the main housing 100 through the fastening unit 500. The fastening unit 500 includes a first fastener 510 that penetrates the lining plate 400, the pressing member 300, the main housing 100 and the switch circuit board 210, and a second fastener 520 that is received in the main housing 100 and is screwed to the first fastener 510.

[0045] In one embodiment, the first fastener 510 is a bolt, and the second fastener 520 is a nut. In another embodiment, the first fastener 510 is a first positioning pin with an end (not shown), and the second fastener 520 is a second positioning pin with an end (not shown), and the free end of the first positioning pin is provided with a threaded hole extending along its axial direction, and the free end of the second positioning pin is provided with a stud section that cooperates with the threaded hole, and the connection is achieved through the cooperation between the threaded hole and the stud section. The following is an example of the case where the first fastener 510 is a bolt and the second fastener 520 is a nut.

[0046] Considering that the endoscope operating components need to be sterilized with high temperature and high pressure or sterilized with ethylene oxide after use, if the sealing of the endoscope operating components is not good, then the relevant chemicals and contaminated liquids will enter the main shell 100 through the gaps and cause damage to the internal circuit boards.

[0047] In order to prevent external media from entering the main housing 100 through the gap between the first fastener 510 and the lining plate 400, the pressing member 300, and the main housing 100, a sealing ring 530 is sleeved on the first fastener 510. The lining plate 400 has a first through hole 430 for the first fastener 510 to pass through, and the sealing ring 530 is sandwiched between the first fastener 510 and the hole wall of the first through hole 430. Figure 8 As shown, a limiting ring 511 is provided on the stud of the bolt, and the limiting ring 511 is arranged close to the end of the bolt, and the sealing ring 530 is axially limited between the end of the bolt and the limiting ring 511.

[0048] like Figure 5 As shown, a sealing ridge 321 is provided on one side of the pressing member 300 close to the main housing 100, and the sealing ridge 321 is provided on the base sheet 320. After the pressing member 300 and the lining plate 400 are provided on the main housing 100 through the fastening unit 500, the first fastener 510 and the second fastener 520 are tightened, at which time, the sealing ridge 321 is squeezed and deformed to prevent the external medium from entering the main housing 100 through the gap between the pressing member 300 and the main housing 100. The sealing ridge 321 and the sealing ring 530 form a multi-directional sealing structure with a good sealing effect.

[0049] There are multiple sealing ridges 321, and the multiple annular sealing ridges 321 are spaced apart in the radial direction of the first fastener 510 to form a multi-level seal. In order to enable the liner 400 to be pressed against the base sheet 320 located inside thereof, the sealing ridges 321 are squeezed and deformed, such as Figure 4 As shown, the thickness N of the base sheet 320 is equal to the thickness M of the convex portion 420. The above-mentioned "thickness" refers to the dimension from the opening to the bottom of the groove. When squeezed, the sealing ridge 321 and the main housing 100 are sealed by interference fit. The force generated between the sealing ridge 321 and the main housing 100 when squeezed can also make the base sheet 320 and the liner 400 tightly abut against each other, further improving the sealing effect.

[0050] The outer circumference of the main housing 100 is provided with a boss 110 protruding outward, a recessed area 111 is formed on the boss 110, and the liner 400 is located in the recessed area 111. The protruding boss 110 increases the volume of the receiving cavity of the main housing 100 to a certain extent, so as to facilitate the arrangement of the switch circuit board assembly 200; in addition, the setting of the boss 110 divides the outer circumference of the main housing 100, the boss 110 area is the operation area, and the area on the side of the boss 110 is the gripping area, which is convenient for the operator to operate.

[0051] A front cover 600 is detachably provided at one end of the main housing 100. The detachable front cover 600 facilitates the disassembly and repair of the circuit board inside the main housing 100. The cable 120 is detachably provided at the other end of the main housing 100. The front cover 600 and the cable 120 are respectively provided at opposite ends of the main housing 100. Figure 4 As shown, a step-shaped structure is formed on the front cover 600, and the front cover 600 is sealedly connected to one end of the main shell 100 through the step-shaped structure.

[0052] like Figure 2 and Figure 4 As shown, the front cover 600 is provided with an image sensor unit 700, and the image sensor unit 700 is accommodated in the main housing 100. The image sensor unit 700 and the front cover 600 form a whole, and can be detachably connected to the main housing 100 together.

[0053] The image sensor unit 700 includes an image sensor 710, an image sensor control board 720, and a transfer circuit board 730. The image sensor 710 is disposed on the inner end surface 610 of the front cover 600 close to the main housing 100, and the image sensor control board 720 and the transfer circuit board 730 are disposed on the inner end surface 610 through a bracket 740. The image sensor control board 720 and the transfer circuit board 730 are disposed on the inner end surface 610 through the same bracket, which is conducive to improving installation efficiency.

[0054] Furthermore, a heat-conducting structure 750 for dissipating heat from the image sensor control board 720 is provided on the bracket 740. The heat-conducting structure 750 may be a heat-conducting silicone sheet or a heat-conducting coating. During operation, the heat generated by the image sensor control board 720 is transferred to the bracket 740 through the heat-conducting structure 750, and the heat on the bracket 740 is dissipated to the outside air through the front cover 600 and the main housing 100, thereby effectively preventing heat from accumulating in the main housing 100.
