[0002] A bronchoscope is a medical device that is inserted into the lower respiratory tract of a patient through the mouth or nose and is used for observing lesions in the lung lobes, segments, and sub-segments, biopsy sampling, bacteriological and cytological examinations. It can be used for photography, teaching, and dynamic recording in cooperation with a TV system. Through the connected biopsy sampling accessory, it can assist in detecting early lesions and perform in-vivo surgical operations such as polyp removal. It is applicable to operations such as bronchial and pulmonary disease research and postoperative examinations. Endobronchial ultrasonography (EBUS) is to use an ultrasonic bronchoscope or insert a micro ultrasonic probe (USP) into the trachea and bronchial lumen through the bronchoscope, and obtain ultrasonic images of each layer of the tracheal and bronchial walls and adjacent organs through real-time ultrasonic scanning, thereby further improving the diagnostic level.

[0003] As one of the important components of an endoscope, a plug connection device is used to connect the endoscope body to an optical host and an ultrasonic host. Among them, the plug connection device is generally connected to the optical host through an adapter device. However, the insertion and extraction of the adapter of the traditional adapter device and the plug connection device are relatively laborious, which is not conducive to the connection between the optical host and the endoscope. Summary of the Invention

[0005] An adapter device is used to connect an ultrasonic probe to an ultrasonic host. The adapter device includes a cable and an adapter. The adapter includes an adapter connector, a hole end seat, an interface locking ring, and a cable fixing member;

[0006] The adapter connector is disposed in the hole end seat and is used for plugging into the optical connection module;

[0007] The cable fixing member is connected to the hole end seat and is used for fixing the tail end of the cable in the hole end seat so that the cable is connected to the adapter connector;

[0008] The interface locking ring is rotatably disposed outside the hole end seat so as to provide a thrust towards the plug connection device to itself when the adapter connector is plugged into the plug connection device of the ultrasonic probe.

[0009] In one embodiment, one of the interface locking ring and the plug connecting device is provided with a boosting protrusion, and the other is provided with a spiral groove along the axial direction of the adapter. The boosting protrusion is received in the spiral groove.

[0010] In one embodiment, the adapter further includes a hole end locking ring. The hole end locking ring is disposed in the hole end seat and is used to cooperate with the interface locking ring to fix the adapter connector.

[0011] In one embodiment, the hole end seat has a first abutting step surface facing the cable, and the adapter connector has a second abutting step surface facing away from the cable. The first abutting step surface abuts against the second abutting step surface, and the end surface of the adapter connector close to the cable abuts against the hole end locking ring.

[0012] In one embodiment, the cable fixing member includes a rear cover, a wire clamping ring and a tail pressing ring; the rear cover has opposite first and second ends. The first end is butted against the hole end seat, and the second end is inserted into the tail pressing ring; the wire clamping ring is disposed between the inner peripheral surface of the second end and the outer peripheral surface of the cable;

[0013] When the tail pressing ring moves towards the adapter connector and is inserted into the rear cover, it can press the wire clamping ring to deform so as to clamp the cable tightly.

[0014] In one embodiment, the inner side of the tail pressing ring has an extrusion surface for pressing the wire clamping ring, and the distance from the extrusion surface to the central axis of the cable gradually increases in the direction close to the adapter connector.

[0015] In one embodiment, the cable fixing member further includes a tail pressing ring housing, and the tail pressing ring housing is sleeved outside the tail pressing ring.

[0016] In one embodiment, the adapter further includes a hole end seat housing. The hole end seat housing is sleeved outside the hole end seat and is connected to the cable fixing member. The end surface of the hole end seat housing away from the cable fixing member abuts against the interface locking ring.

[0017] In one embodiment, the adapter may further include an interface locking ring housing, and the interface locking ring housing is sleeved outside the interface locking ring.

[0018] An endoscope system includes an endoscope, an optical host, an image host, an ultrasonic probe, an ultrasonic host, a plug connecting device and the adapter device as described in any one of the above; the plug connecting device is provided with an optical and image connection module and an ultrasonic connection module;

[0019] The endoscope is provided with a mirror body, which is connected to the optical and image connection module. The optical and image connection module is connected to the optical host and the image host. The ultrasonic probe is fixedly arranged at the distal end of the mirror body and is connected to the ultrasonic connection module through an ultrasonic wire. The adapter of the adapter device is plugged into the ultrasonic connection module, and the cable of the adapter device is connected to the ultrasonic host.

[0020] For the above-mentioned adapter device and endoscope system, when the adapter connector of the adapter is plugged into the plug connection device of the ultrasonic probe for a certain distance, the operator can rotate the interface locking ring of the adapter. During the rotation process, the interface locking ring provides a thrust towards the plug connection device by cooperating with the plug connection device of the ultrasonic probe, making the plugging of the adapter connector and the plug connection device more labor-saving, so as to realize the quick connection between the ultrasonic host and the plug connection device on the endoscope.

[0033] As Figure 1 and Figure 2 As shown, an embodiment of the present application provides an adapter device for connecting an ultrasonic probe to an ultrasonic host. Among them, the ultrasonic probe is connected to a plug connection device 10 on the proximal end of the endoscope through an ultrasonic wire. It should be noted that this adapter device is not only applied to the plug connection device of the ultrasonic endoscope, but can also be applied to the plug connection devices of other electronic devices.

[0034] The endoscope can be an endoscope such as a bronchoscope or a laparoscope. The endoscope is provided with a mirror body 50, and the mirror body 50 has a light-conducting optical fiber, an optical wire for transmitting an optical image signal, and an ultrasonic wire for transmitting an ultrasonic image signal. Among them, the ultrasonic probe is fixedly arranged at the distal end of the mirror body 50 of the endoscope. The ultrasonic probe can be a convex array probe, etc. The distal end of the ultrasonic wire is connected to the ultrasonic probe, and the proximal end of the ultrasonic wire is connected to the plug connection device 10.

[0035] The plug connection device 10 is arranged at the proximal end of the mirror body 50 and is provided with an optical and image connection module and an ultrasonic connection module. The optical and image connection module is connected to the optical fiber and the optical host to provide a lighting source; the optical and image connection module is also connected to the optical wire and the image host to transmit an optical image signal. The ultrasonic connection module is connected to the ultrasonic wire and the ultrasonic host to transmit ultrasonic signals.

[0036] Among them, the ultrasonic host is connected to the ultrasonic connection module of the plug connection device 10 through the adapter device. As Figure 1 and Figure 2As shown, the adapter device includes a cable 20 and an adapter 30. The cable 20 is connected to the ultrasound main unit, and the adapter 30 is plugged into the ultrasound connection module of the plug connection device 10.

[0037] It can be understood that the adapter 30 of the adapter device needs to match the structure of the ultrasound connection module of the plug connection device 10 so that the two can be normally plugged in.

[0038] Refer again to Figure 2 , in some embodiments, the adapter 30 may include an adapter connector 30a, a hole end seat 30b, an interface locking ring 30c, and a cable fixing member 30d; the adapter connector 30a is disposed in the hole end seat 30b and is used to dock with the ultrasound connection module of the plug connection device; the cable fixing member 30d is connected to the hole end seat 30b and is used to fix the tail end of the cable 20 in the hole end seat 30b so that the cable 20 is connected to the adapter connector 30a; the interface locking ring 30c is rotatably sleeved outside the hole end seat 30b to provide a thrust force towards the plug connection device to itself when the adapter connector 30a is plugged into the plug connection device.

[0039] Among them, one of the adapter connector 30a of the adapter 30 and the ultrasound connection module is a female head, and the other is a male head. Exemplarily, the adapter connector 30a of the adapter 30 is a female head, and the ultrasound connection module is a male head.

[0040] After the adapter connector 30a of the adapter 30 is plugged into the plug connection device for a certain distance, the operator can rotate the interface locking ring 30c of the adapter 30. During the rotation process, the interface locking ring 30c provides a thrust force towards the plug connection device to itself by cooperating with the ultrasound connection module, making the plugging of the adapter connector 30a and the plug connection device more labor-saving.

[0041] Such as Figure 3 and Figure 4 shown, in one embodiment, one of the plug connection device and the interface locking ring 30c is provided with a boosting protrusion, and the other is provided with a spiral groove along the axial direction of the adapter 30. The boosting protrusion is received in the spiral groove. When the interface locking ring 30c of the adapter 30 is rotated, the boosting protrusion can slide along the spiral groove, so that the interface locking ring 30c can provide a thrust force towards the plug connection device to itself.

[0042] As an example, the boosting protrusion 321 is disposed on the outer peripheral surface of the ultrasound connector 320, and the spiral groove 30c1 is disposed on the interface locking ring 30c and penetrates the circumferential side wall of the interface locking ring 30c.

[0043] To prevent the hole end seat 30b from rotating together with the interface locking ring 30c when the transfer connector 30a is docked with the plug connecting device, a positioning portion is provided on the outer peripheral surface of the hole end seat 30b, and the positioning portion is a convex structure or a groove structure.

[0044] Refer again to Figure 2 , in some embodiments, the adapter 30 may further include a hole end locking ring 30e. The hole end locking ring 30e is disposed within the hole end seat 30b and is used to cooperate with the interface locking ring 30c to fix the transfer connector 30a. The hole end locking ring 30e can be connected to the hole end seat 30b by means of snap connection, threaded connection, etc.

[0045] In one embodiment, the hole end seat 30b has a first abutting step surface facing the cable 20, and the transfer connector 30a has a second abutting step surface facing away from the cable 20. The first abutting step surface abuts against the second abutting step surface, and the end surface of the transfer connector 30a close to the cable 20 abuts against the hole end locking ring 30e. By clamping between the first abutting step surface and the hole end locking ring 30e, it is convenient to disassemble and assemble the transfer connector 30a.

[0046] Continue to refer to Figure 2 , in some embodiments, the adapter 30 may further include a hole end seat housing 30f. The hole end seat housing 30f is sleeved outside the hole end seat 30b and is connected to the cable fixing member 30d. The end surface of the hole end seat housing 30f away from the cable fixing member 30d abuts against the interface locking ring 30c. By the hole end seat housing 30f abutting against the interface locking ring 30c, the circumferential position of the interface locking ring 30c can be relatively fixed. Among them, the hole end seat housing 30f can be connected to the cable fixing member 30d by means of threaded members, welding, clamping, etc.

[0047] Continue to refer to Figure 2 , in some embodiments, the adapter 30 may further include an interface locking ring housing 30g. The interface locking ring housing 30g is sleeved outside the interface locking ring 30c. The interface locking ring housing 30g can be made of plastic material, which is convenient for the operator to hold. Among them, the interface locking ring housing 30g can be installed outside the interface locking ring 30c by means of threads, screws, bonding, etc.

[0048] Continue to refer to Figure 2, in some embodiments, the cable fixing member 30d may include a rear cover 30d1, a wire clamping ring 30d2 and a tail pressing ring 30d3; the rear cover 30d1 has opposite first and second ends, the first end of the rear cover 30d is butted against the hole end seat 30b, and the second end of the rear cover 30d1 is inserted into the tail pressing ring 30d3; the wire clamping ring 30d2 is disposed between the inner circumferential surface of the second end of the rear cover 30d1 and the outer circumferential surface of the cable 20; when the tail pressing ring 30d3 moves toward the adapter connector 30a and is inserted into the second end of the rear cover 30d1, it can compress the wire clamping ring 30d2 to deform, so as to tightly hold the tail end of the cable 20. Among them, the tail pressing ring 30d3 can be threadedly connected to the second end of the rear cover 30d1. When the tail pressing ring 30d3 is screwed toward the adapter connector 30a, the tail pressing ring 30d3 can compress the wire clamping ring 30d2 to deform, so that the tail pressing ring 30d3 can tightly hold the tail of the cable 20, thereby locking the tail of the cable 20 in the hole end seat 30b.

[0049] The rear cover 30d can be a shell structure with a central cavity and can be used for the cable 20 to pass through. It should be noted that the central cavities of the tail pressing ring 30d3 and the wire clamping ring 30d2 are also used for the cable 20 to pass through.

[0050] See Figure 2 , the inner side of the tail pressing ring 30d3 has an extrusion surface L for pressing the wire clamping ring 30d2, and the distance from the extrusion surface L to the central axis of the cable 20 gradually increases in the direction close to the adapter connector 30a. By setting the extrusion surface L in this way, when the tail pressing ring 30d3 is screwed toward the adapter connector 30a, the tail pressing ring 30d3 can gradually compress the wire clamping ring 30d2 to deform, avoiding damage to the cable 20 due to excessive deformation of the wire clamping ring 30d2 at one time.

[0051] Among them, the extrusion surface L can be an inclined surface or a curved surface.

[0052] Continue to see Figure 2 , the cable fixing member 30d further includes a tail pressing ring housing 30d4, and the tail pressing ring housing 30d4 is sleeved outside the tail pressing ring 30d3. The tail pressing ring housing 30d4 can be made of plastic material, which is convenient for the operator to screw. Among them, the tail pressing ring housing 30d4 can be installed outside the tail pressing ring 30d3 by means of threads, screws, bonding, etc.

[0053] Among them, the tail pressing ring housing 30d4 has an opening communicating with its inner cavity, and the opening can be used for the cable 20 to pass through

[0054] On the other hand, an embodiment of the present application further provides an endoscope system, which includes an endoscope, an optical host, an image host, an ultrasound probe, an ultrasound host, a plug connection device, and a switching device as described in any of the above; the plug connection device is provided with an optical and image connection module and an ultrasound connection module; the endoscope is provided with a mirror body 50, the mirror body 50 is connected to the optical and image connection module, the optical and image connection module is connected to the optical host and the image host, the ultrasound probe is fixed at the distal end of the mirror body 50 of the endoscope, the ultrasound probe is connected to the ultrasound connection module through an ultrasound wire, the adapter 30 of the switching device is connected to the ultrasound connection module, and the cable 20 of the switching device is connected to the ultrasound host. As an example, the ultrasound probe can be a convex array probe, etc.

[0055] The endoscope may be a bronchoscope, a laparoscope or the like, and the endoscope body 50 includes light-guiding optical fibers, optical wires for transmitting optical image signals, and the ultrasonic wires for transmitting ultrasonic image signals.

[0056] The plug connection device 10 is arranged at the proximal end of the scope 50, and is provided with an optical and image connection module and an ultrasound connection module. The optical and image connection module is connected to the optical fiber and the optical host to provide an illumination light source; the optical and image connection module is also connected to the optical wire and the image host to transmit the optical image signal. The ultrasound connection module is connected to the ultrasound wire and the ultrasound host to transmit the ultrasound signal.

[0057] In this endoscope system, after the adapter connector 30a of the adapter 30 is plugged into the plug connector of the plug connection device for a certain distance, the operator can rotate the interface locking ring 30c of the adapter 30. During the rotation, the interface locking ring 30c cooperates with the plug connection device to provide a thrust toward the plug connection device 10, thereby making the plugging of the adapter connector 30a and the plug connection device 10 more labor-saving.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
