Therefore, the various embodiments throughout the specification do not necessarily refer to the same embodiment.

In the various embodiments and implementation methods of this utility model, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the implementation methods of different embodiments are consistent and can be mutually referenced. The technical features in different embodiments and between the implementation methods of different embodiments can be combined according to their inherent logical relationships to form new embodiments, implementation methods, implementation methods, or implementation approaches. The following embodiments of this utility model do not constitute a limitation on the scope of protection of this utility model.
[0025] The endoscope host can be connected to the endoscope body through the endoscope body interface device. The data from the endoscope body is transmitted to the image processor of the endoscope host for processing through the endoscope body interface device to realize the internal examination.
[0026] When the endoscope body is inserted into the endoscope body interface device via hot-swapping, the endoscope body interface device is already powered on, which can cause an electric arc between the power contact springs of the endoscope body and the endoscope body interface device, thereby damaging the endoscope main unit.
[0027] To address the aforementioned problems, this utility model provides an endoscope body interface device, such as... Figure 1 As shown, the endoscope body interface device 10 includes a guide section 101 and a connecting section 102 arranged sequentially along the axis. Multiple spring clips are distributed circumferentially along the inner wall of the connecting section 102.
[0028] The guide section 101 guides the insertion of the endoscope body, and the conductive section 102 is used for electrical connection with the endoscope body. The spring includes a grounding spring 103 and a power spring 104. The distance between the contact of the grounding spring 103 and the end of the guide section 101 near the conductive section 102 is a first distance, and the distance between the contact of the power spring 104 and the end of the guide section 101 near the conductive section 102 is a second distance. The first distance is less than the second distance.
[0029] Based on this scheme, since the first distance is the distance between the contact of the grounding spring 103 and the end of the guide section 101 near the conducting section 102, and the second distance is the distance between the contact of the power spring 104 and the end of the guide section 101 near the conducting section 102, and since the first distance is less than the second distance, when the endoscope body and the endoscope body interface device 10 are hot-plugged, the endoscope body can first contact the contact of the grounding spring 103 and then contact the contact of the power spring 104, thereby avoiding the generation of an electric arc between the endoscope body and the power contact spring of the endoscope body interface device 10, and reducing the damage to the endoscope host. It should be noted that the inner diameter of the guide section 101 matches the outer diameter of the insertion section of the endoscope body, allowing the endoscope body to be inserted.
[0030] In a design, such as Figure 1 As shown, the spring also includes a signal transmission spring 105. The distance between the contact of the signal transmission spring 105 and the end of the guide section 101 near the conducting section 102 is the third distance, and the second distance is less than the third distance.
[0031] Based on this design, since the distance between the contact of the signal transmission spring 105 and the end of the guide section 101 near the conduction section 102 is the third distance, and the second distance is less than the third distance, after there is good electrical contact between the endoscope body and the endoscope body interface device 10, data can be transmitted between the endoscope body and the endoscope body interface device 10 through the signal transmission spring 105, which can improve the stability of data transmission.
[0032] As one possible implementation, to achieve a first distance less than a second distance, and a second distance less than a third distance, such as... Figures 2a-2b As shown, the inner wall of the conductive section 102 is circumferentially recessed with multiple grooves, each groove for accommodating a spring contact. The grooves include a first groove 1027 for accommodating a grounding spring contact 103, a second groove 1021 for accommodating a power supply spring contact 104, and a third groove 1022 for accommodating a signal transmission spring contact 105. The contacts of the spring contact are all located at the bottom of the grooves. The distance between the bottom of the first groove 1027 and the end of the guide section 101 near the conductive section 102 is less than the distance between the bottom of the second groove 1021 and the end of the guide section 101 near the conductive section 102, and the distance between the bottom of the second groove 1021 and the end of the guide section 101 near the conductive section 102 is less than the distance between the bottom of the third groove 1022 and the end of the guide section 101 near the conductive section 102.
[0033] Based on this possible implementation, the contacts of the springs are all located at the bottom of the grooves. Since the distance between the bottom of the first groove 1027 used to accommodate the grounding spring 103 and the end of the guide section 101 near the conducting section 102 is less than the distance between the bottom of the second groove 1021 used to accommodate the power spring 104 and the end of the guide section 101 near the conducting section 102, the first distance can be less than the second distance, and the second distance can be less than the third distance.
[0034] As another possible implementation, in order to achieve the first distance being less than the second distance and the second distance being less than the third distance, the inner wall of the conductive section 102 is provided with a plurality of grooves in the circumferential direction, each groove being used to accommodate a spring piece, and at least one of the grooves and the spring piece is provided with a limiting structure, the limiting structure being used to limit the depth of each spring piece inserted into the groove.
[0035] It is worth noting that in this implementation, the contact point of the spring is equidistant from the end of the spring near the bottom of the groove.
[0036] As an example, such as Figures 3a-3b As shown, the grooves include a fourth groove 1028 for accommodating a grounding spring 103, a fifth groove 1023 for accommodating a power supply spring 104, and a sixth groove 1024 for accommodating a signal transmission spring 105. The fourth groove 1028, fifth groove 1023, and sixth groove 1024 are each provided with a limiting structure. The limiting structure of the fourth groove 1028 causes the depth to which the grounding spring 103 is inserted into the fourth groove 1028 to be greater than the depth to which the power supply spring 104 is inserted into the fifth groove 1023, and the limiting structure of the fifth groove 1023 causes the depth to which the power supply spring 104 is inserted into the fifth groove 1023 to be greater than the depth to which the signal transmission spring 105 is inserted into the sixth groove 1024.
[0037] It should be noted that in this implementation, the distance between the bottom of each groove and the end of the guide segment 101 near the conduction segment 102 can be the same or different, and this utility model does not impose specific restrictions on this.
[0038] In some embodiments, a limiting structure may also be provided on the spring to limit the depth to which each spring is inserted into the groove.
[0039] In some other embodiments, mutually cooperating limiting structures may be provided on both the groove and the spring piece to limit the depth to which each spring piece is inserted into the groove.
[0040] Based on this possible implementation, since the distance between the bottom of each groove and the end of the guide section 101 near the conduction section 102 is equal, at least one of the groove and the spring is provided with a limiting structure. The limiting structure is used to limit the depth of each spring inserted into the groove. Therefore, the depth of the spring inserted into the groove can be controlled by the limiting structure, thereby achieving a first distance less than a second distance, and a second distance less than a third distance.
[0041] As another possible implementation, to achieve a first distance less than a second distance, and a second distance less than a third distance, the spring is strip-shaped, with its length direction parallel to the circumferential direction of the conducting section 102; the spring includes a first end and a second end along its length direction, with the second end close to the guiding section 101; wherein, the distance between the contact of the grounding spring 103 and the second end is less than the distance between the contact of the power spring 104 and the second end, and the distance between the contact of the power spring 104 and the second end is less than the distance between the contact of the signal transmission spring 105 and the second end.
[0042] Based on this possible implementation, the second end of the spring is close to the guide section 101. Since the distance between the contact of the grounding spring 103 and the second end is less than the distance between the contact of the power spring 104 and the second end, and the distance between the contact of the power spring 104 and the second end is less than the distance between the contact of the signal transmission spring 105 and the second end, it is possible to achieve that the first distance is less than the second distance and the second distance is less than the third distance.
[0043] In a design, such as Figure 4 As shown, at least a portion of the end face of the conducting segment 102 near the guide segment 101 is recessed in a direction away from the guide segment 101 to form a recessed guide segment 1025. An optical fiber interface 1026 is provided at the bottom of the recessed guide segment 1025, and the axis of the optical fiber interface 1026 is parallel to the axis of the conducting segment 102.
[0044] It should be noted that the ratio of the area of the recessed portion of the end face of the conducting segment 102 near the guide segment 101 in the direction away from the guide segment 101 to the area of the end face of the conducting segment 102 near the guide segment 101 can be 1 / 5, 2 / 5, 1 / 10, etc., and this utility model does not impose specific limitations on this.
[0045] Based on this design, at least a portion of the end face of the conducting section 102 near the guiding section 101 is recessed away from the guiding section 101, forming a recessed guiding section 1025. A fiber optic interface 1026 is provided at the bottom of the recessed guiding section 1025. The axis of the fiber optic interface 1026 is parallel to the axis of the conducting section 102. The recessed guiding section 1025 can automatically guide the fiber optic plug into the fiber optic interface 1026 through geometric constraints, reducing the deviation of the light insertion angle and improving the convenience of fiber optic connection. At the same time, the recessed guiding section 1025 also fixes the fiber optic plug, reducing the displacement between the fiber optic plug and the fiber optic interface 1026 caused by external vibration or bending, and improving the stability of fiber optic connection.
[0046] In a design, such as Figure 1 As shown, a positioning protrusion 1011 is provided along the inner wall of the guide section 101. The positioning protrusion 1011 is used to guide the endoscope body to move along the axial direction of the endoscope body interface device 10 and to limit it, thereby ensuring the installation position accuracy of the endoscope body.
[0047] The number and position of the positioning protrusions 1011 match the positioning grooves of the endoscope body. If there are two positioning grooves on the endoscope body, there are also two positioning protrusions 1011. If there are three positioning grooves on the endoscope body, there are also three positioning protrusions 1011.
[0048] The end of the positioning protrusion 1011 away from the conductive section 102 is provided with a certain angle, which is conducive to the guide groove of the lens body sliding in. For example, the end of the positioning protrusion 1011 away from the conductive section 102 is provided with an angle of 20°, 30° or 40°, and this utility model does not make specific limitations in this regard.
[0049] Because the inner wall of the guide section 101 is provided with a positioning protrusion 1011, when the endoscope body is inserted, the positioning groove of the endoscope body is aligned with the positioning protrusion 1011 and inserted, which can guide the endoscope body to move along the axial direction of the endoscope body interface device 10. The presence of the positioning protrusion 1011 will prevent relative circumferential rotation between the endoscope body and the endoscope body interface device 10, thereby improving the positional accuracy of the connection between the endoscope body and the endoscope body interface device 10.
[0050] In a design, such as Figure 4 As shown, the endoscope body interface device 10 also includes an elastic clamping member 106 and a ball bearing 107. The inner wall of the guide section 101 is provided with a tapered hole for the ball bearing 107 to partially extend into. The elastic clamping member 106 is used to press the ball bearing 107 into the tapered hole.
[0051] The smaller diameter end of the tapered hole faces the axis of the guide section 101. A portion of the ball 107 can extend into the guide section 101 through the smaller diameter end of the tapered hole, while the larger diameter end of the tapered hole exposes a portion of the ball 107 so that it can be pressed into the tapered hole by the elastic clamping member 106.
[0052] After the endoscope body is inserted into the guide section 101 of the endoscope body interface device 10, the endoscope body will push the ball 107 outward, causing the ball 107 to move towards the large diameter end of the conical hole. However, under the pressure of the elastic clamping member 106, the ball 107 will not detach from the large diameter end of the conical hole. Finally, the ball 107 passes through the small diameter end of the conical hole and is pressed against the endoscope body, thereby improving the stability of the connection between the endoscope body and the endoscope body interface device 10, without affecting insertion and removal. Moreover, even if wear occurs between the endoscope body and the guide section 101 of the endoscope body interface device 10, the ball 107 and the elastic clamping member 106 can still adaptively clamp the endoscope body, improving the stability of the connection between the endoscope body and the endoscope body interface device 10.
[0053] Furthermore, such as Figure 4 As shown, the endoscope body interface device 10 also includes a light guide interface 108 and an air supply interface 109.
[0054] The light guide interface 108 is connected to a light source device. After the endoscope body and the endoscope body interface device 10 are connected, the light source device can provide illumination to the endoscope body through the light guide interface 108.
[0055] An air pump is connected to the air supply port 109. After the endoscope body and the endoscope body interface device 10 are connected, the air pump supplies air into the cavity through the air supply port 109 and the endoscope body.
[0056] In a design, such as Figure 5 As shown, the endoscope body interface device 10 also includes an annular circuit board 11, which includes multiple insertion slots 111, and the multiple insertion slots 111 are electrically connected to multiple spring contacts one by one.
[0057] The ring circuit board 11 can be a PCBA circuit board or a SiP circuit board. Of course, the ring circuit board 11 can also be other types of circuit boards. This utility model does not impose specific limitations on this.
[0058] Based on this design, since the endoscope body interface device 10 also includes a ring circuit board 11, which includes multiple insertion slots 111, and the multiple insertion slots 111 are electrically connected to multiple spring contacts one by one, the circuit board can receive and process the signal data of the endoscope body, thereby realizing the work of internal examination.
[0059] In a design, such as Figures 6a-6c As shown, the contact point of the spring is provided with a protrusion 12, which is located on the insertion path of the plug of the endoscope body.
[0060] It should be noted that the protrusion 12 can be an arc-shaped protrusion, a pointed protrusion, or a rectangular protrusion, and this utility model does not impose specific limitations on it. Preferably, as shown in FIG6, the protrusion 12 is an arc-shaped protrusion.
[0061] Because the contact point of the spring is provided with a protrusion 12, which is located on the insertion path of the endoscope body plug, the endoscope body plug contacts the protrusion 12 to transmit data. This can reduce the contact area between the endoscope body plug and the spring, reduce the wear of the endoscope body and the endoscope body interface device 10. At the same time, because the protrusion 12 can exert a certain pressure on the endoscope body plug, it can increase the stability of the connection between the endoscope body plug and the endoscope body interface device 10.
[0062] The contact point of the spring is located on the insertion path of the endoscope plug. When the endoscope plug is inserted into the guide section 101, the endoscope plug will extend into the conductive section 102 of the endoscope interface device 10. The contact point of the spring on the inner wall of the conductive section 102 will make contact with the endoscope plug and conduct. Then, the data monitored by the endoscope is transmitted from the endoscope plug to the circuit board for processing through the contact point of the spring, so as to realize the internal examination.
[0063] like Figure 7-8 As shown, this utility model also provides an endoscope host 20, which includes the endoscope body interface device 10 provided in the above embodiments. The technical effects of the endoscope host provided by this utility model can be found in the technical effects brought about by the endoscope body interface device 10 in the above embodiments, and will not be repeated here.
[0064] The endoscope host 20 and endoscope body interface device 10 are described above as illustrative embodiments of the present invention and should not be construed as limiting the present invention. Furthermore, various modifications listed herein, as well as variations in methods and compositions within the invention, will be apparent to those skilled in the art without departing from the scope and spirit of the present invention. Although the present invention has been specifically described in conjunction with various specific preferred embodiments, it should be understood that the present invention should not be limited to these specific embodiments. In fact, various modifications as described above, which are obvious to those skilled in the art, to obtain the invention should be included within the scope of the present invention.
