Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bridge for endoscopes and an endoscope system. Background Technology

[0002] During endoscopic procedures, saline solution is typically used for flushing. To ensure pressure balance within the body, aspiration is performed after flushing, and the aspirated fluid is disposed of as medical waste. Endoscopic aspiration can also be used when it is necessary to remove and analyze organic material samples from specific areas of the body.

[0003] In existing technology, a bridging device is installed between the endoscope and the sampling device. The bridging device has a valve body for adjusting the suction and sampling settings. In the suction setting, the fluid aspirated by the endoscope is directly discharged after passing through the bridging device; in the sampling setting, the fluid aspirated by the endoscope enters the sampling device through the bridging device. However, existing bridging devices divide the entire space within the valve body into multiple narrow chambers. Each chamber must connect to both the inlet and outlet of the bridging device, resulting in narrow passageways at the connections and thus affecting fluid flow. Furthermore, some bridging devices are directly connected to the vacuum pump tube of the suction mechanism, causing the bridging device to occupy a large space, obstructing the grip of the endoscope, and making it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a bridge for endoscopes and an endoscope system. The bridge reduces flow rate loss during gear switching. At the same time, the bridge occupies less space and is easier to hold the endoscope.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On the one hand, a bridging device for an endoscope is provided, disposed between the endoscope and a sampling device; a suction mechanism is connected to the sampling device;

[0007] The bridge includes:

[0008] The main structure has a liquid inlet channel, a first liquid outlet channel and a second liquid outlet channel. The liquid inlet channel is connected to the endoscope, and the first liquid outlet channel and the second liquid outlet channel are both connected to the sampling device.

[0009] The valve body is movably mounted on the main structure, and the valve body is provided with a communicating chamber, the communicating chamber being provided with a protrusion; the valve body has a suction position and a sampling position;

[0010] When the suction setting is engaged, the protrusion blocks the inlet of the second liquid outlet channel, and both the liquid inlet channel and the first liquid outlet channel are connected to the connecting chamber.

[0011] When the sampling position is selected, the protrusion blocks the inlet of the first liquid outlet channel, and both the liquid inlet channel and the second liquid outlet channel are connected to the connecting chamber.

[0012] As an alternative to the bridge, the protrusion is arc-shaped or strip-shaped.

[0013] As an alternative to the bridge, the valve body is rotatably mounted on the main structure;

[0014] Alternatively, the valve body can be slidably disposed on the main body structure;

[0015] Alternatively, the valve body may be movably disposed within the main body structure.

[0016] As an alternative to the bridge, the bridge also includes a knob, which is rotatably mounted on the main structure. The knob has a mounting groove, and the valve body is embedded in the mounting groove.

[0017] As an alternative to the bridge, the bridge also includes a housing that covers the main structure and has a through hole that allows the knob to pass through;

[0018] The housing is provided with suction mode markings and sampling mode markings, and the knob is provided with an identification part;

[0019] When the valve body is in the suction position, the marking part is aligned with the suction position mark;

[0020] When the valve body is in the sampling position, the marking part is aligned with the sampling position mark.

[0021] As an optional solution for the bridge, the knob is provided with an operating part on its exterior, and the operating part is provided with an anti-slip structure.

[0022] As an optional bridging device, the endoscope's suction end is provided with a connecting pipe, and the main structure has an insertion channel that connects to the liquid inlet channel.

[0023] The bridge also includes a locking element, the main structure has a locking groove, the insertion channel passes through the locking groove and is connected to the locking groove; the locking element can be engaged in the locking groove to lock the connector in the insertion channel.

[0024] As an alternative to the bridge, a first seal is provided in the liquid inlet channel, which is used to seal the gap between the end of the connector and the liquid inlet channel.

[0025] As an alternative to the bridge, the outer wall of the main structure is provided with a second sealing element, which is used to seal the connection between the first liquid outlet channel and the sampling device, and to seal the connection between the second liquid outlet channel and the sampling device.

[0026] On the other hand, an endoscope system is provided, comprising:

[0027] Endoscope;

[0028] Sampling device;

[0029] The bridge described above is connected between the endoscope and the sampling device.

[0030] The beneficial effects of this utility model are:

[0031] This invention provides a bridging device and endoscope system for an endoscope. The bridging device includes a main structure and a valve body. Liquid drawn from the endoscope's suction end enters the inlet channel of the main structure. When suction is required, the valve body is adjusted to seal the inlet of the second outlet channel, connecting the inlet channel and the first outlet channel in a connecting chamber. This allows the liquid to be delivered to the sampling device via the first outlet channel, completing the suction. When sampling is required, the valve body is adjusted to seal the inlet of the first outlet channel, connecting the inlet channel and the second outlet channel in a connecting chamber. This allows the liquid to be delivered to the sampling device via the second outlet channel, completing the sampling. The protrusion significantly reduces the time for switching between settings, minimizes flow rate loss, and reduces the impact of state switching on the amount of liquid in the sampling device.

[0032] In the endoscopic system, the suction end of the suction mechanism is directly connected to the sampling device, rather than directly to the bridge, which simplifies the space occupied by the bridge, makes it easier for doctors to hold and operate the endoscope, and improves the comfort and convenience of use.

[0056] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0057] This embodiment provides a bridge for an endoscope. For example... Figure 1 and Figure 2 As shown, the bridging device is positioned between the endoscope 100 and the sampling device 200. (Refer to...) Figure 3The endoscope 100 is provided with an suction end 101 and an extraction end 102. The endoscope 100 includes an insertion part and a holding part. The insertion part is used for insertion into the human body, and the suction end 101 is located in the insertion part. The holding part includes a handle for gripping and a suction button. The extraction end 102 is located in the holding part and is connected to the suction end of the suction mechanism. The suction button is used to control whether the suction end of the suction mechanism is connected to the suction end 101 of the endoscope 100. Pressing the suction button connects the suction end of the suction mechanism to the suction end 101 of the endoscope 100, allowing fluid to be extracted from the human body. The holding part also has a working channel for the entry and exit of accessories of the endoscope 100. The sampling device 200 is provided with a first inlet 201 and a second inlet 202. The suction end of the suction mechanism is connected to the sampling device 200 and communicates with the first inlet 201.

[0058] like Figures 4 to 9 As shown, the bridging device includes a main structure 1 and a valve body 2. The main structure 1 has an inlet channel, a first outlet channel, and a second outlet channel. The inlet channel is connected to the endoscope 100, and both the first and second outlet channels are connected to the sampling device 200. The valve body 2 is movably mounted on the main structure 1 and has a connecting chamber 21 with a protrusion 22. The valve body 2 has a suction setting and a sampling setting. In the suction setting, the protrusion 22 blocks the inlet of the second outlet channel, and both the inlet channel and the first outlet channel are connected to the connecting chamber 21. In the sampling setting, the protrusion 22 blocks the inlet of the first outlet channel, and both the inlet channel and the second outlet channel are connected to the connecting chamber 21.

[0059] Specifically, the main structure 1 has an interface 11, a first valve port 12, a suction valve port 13, a sampling valve port 14, a suction outlet 15, and a sampling outlet 16. The inlet channel connects the interface 11 and the first valve port 12, and the interface 11 is connected to the suction end 102 of the endoscope 100; the first outlet channel connects the suction valve port 13 and the suction outlet 15, and the suction outlet 15 is connected to the first inlet 201 of the sampling device 200; the second outlet channel connects the sampling valve port 14 and the sampling outlet 16, and the sampling outlet 16 is connected to the second inlet 202 of the sampling device 200. The suction valve port 13 and the sampling valve port 14 can be respectively connected to the first valve port 12.

[0060] When in suction mode, protrusion 22 blocks sampling valve port 14. First valve port 12 and suction valve port 13 are both connected to connecting chamber 21, so that the liquid inlet channel is connected to the first liquid outlet channel. Then, the liquid aspirated by endoscope 100 can be sent to suction outlet 15 through suction valve port 13 and then enter the first inlet 201 of sampling device 200 to complete suction.

[0061] When in the sampling position, the protrusion 22 blocks the suction valve port 13. The first valve port 12 and the sampling valve port 14 are both connected to the connecting chamber 21, so that the liquid inlet channel is connected to the second liquid outlet channel. Then, the liquid aspirated by the endoscope 100 is sent to the sampling outlet 16 through the sampling valve port 14, and then enters the second inlet 202 of the sampling device 200 to complete the sampling.

[0062] In other words, when suction is required, the sampling valve port 14 is blocked by the protrusion 22, and the liquid inlet channel is connected to the first liquid outlet channel; when sampling is required, the suction valve port 13 is blocked by the protrusion 22, and the liquid inlet channel is connected to the second liquid outlet channel. The protrusion 22 can significantly reduce the time of gear switching, reduce flow rate loss, and reduce the impact on the amount of liquid in the sampling device 200 during the state switching process.

[0063] Optionally, the protrusion 22 is arc-shaped or strip-shaped, which can further shorten the time for the protrusion 22 to switch from the state of blocking the sampling valve port 14 to the state of blocking the suction valve port 13. Specifically, in this embodiment, the protrusion 22 is arc-shaped.

[0064] Optionally, the valve body 2 is rotatably mounted on the main structure 1; or, the valve body 2 is slidably mounted on the main structure 1; or, the valve body 2 is movable on the main structure 1. Any configuration that allows the valve body 2 to switch between the suction and sampling positions is acceptable. Specifically, in this embodiment, the valve body 2 is rotatably mounted on the main structure 1.

[0065] Specifically, in this embodiment, the protrusion 22 is disposed on the bottom wall of the communicating chamber 21; in other embodiments, the protrusion 22 may also be disposed on the side wall of the communicating chamber 21.

[0066] Optionally, such as Figures 4 to 6 As shown, the bridge also includes a knob 3, which is rotatably mounted on the main structure 1. The knob 3 has a mounting groove into which the valve body 2 is embedded. Rotating the knob 3 will cause the valve body 2 to rotate as well, facilitating operation.

[0067] Furthermore, referring to Figure 4 and Figure 5 The bridge also includes a housing 4, which covers the main structure 1 to provide some protection. The housing 4 has a through hole 41 allowing the knob 3 to pass through. The housing 4 is provided with a suction position mark 42 and a sampling position mark 43, and the knob 3 is provided with an indicator 31. When the valve body 2 is in the suction position, the indicator 31 of the knob 3 is aligned with the suction position mark 42 of the housing 4; when the valve body 2 is in the sampling position, the indicator 31 of the knob 3 is aligned with the sampling position mark 43 of the housing 4. This design allows doctors to easily identify the bridge's position status, improving efficiency.

[0068] Optionally, continue to refer to Figure 4 and Figure 5 The knob 3 has an operating part 32 on its exterior to facilitate rotation by the doctor. Specifically, in this embodiment, the operating part 32 is raised. The operating part 32 is also provided with an anti-slip structure, specifically, the anti-slip structure is an anti-slip pad, such as a rubber pad; or, the anti-slip structure is an anti-slip protrusion, which can be dot-shaped protrusions or textured protrusions of any shape, as long as it can increase the contact friction between the user's hand and the operating part 32. Its specific form is in accordance with the prior art and is not specifically limited in this embodiment.

[0069] Optionally, such as Figure 3 As shown, the suction end 102 of the endoscope 100 is provided with a connecting tube 103. For example... Figure 6 As shown, the main structure 1 has an insertion channel 17, which connects to the liquid inlet channel. The connecting pipe 103 passes through the interface 11, through the insertion channel 17, and extends into the liquid inlet channel to deliver the liquid aspirated by the endoscope 100 to the first valve port 12. Combined with... Figure 5 The bridge also includes a locking element 5. The main structure 1 has a locking groove 18, and the insertion channel 17 passes through the locking groove 18 and is connected to the locking groove 18. The locking element 5 can be engaged in the locking groove 18 to lock the connector 103 in the insertion channel 17. The above configuration can ensure the stability of the connection between the endoscope 100 and the bridge.

[0070] Furthermore, a first seal is provided within the liquid inlet channel. The first seal is used to seal the gap between the end of the connector 103 and the liquid inlet channel to prevent liquid leakage. Specifically, the first seal is annular to circumferentially block the gap between the end of the connector 103 and the liquid inlet channel.

[0071] Specifically, refer to Figure 5 A gasket 6 is provided between the knob 3 and the valve body 2. The gasket 6 covers the valve body 2 and is embedded in the mounting groove of the knob 3. On the one hand, the gasket 6 can seal the gap between the knob 3 and the valve body 2, improving the sealing performance of the valve body 2; on the other hand, the gasket 6 can press against the first sealing element, ensuring the stability of the first sealing element.

[0072] Optionally, such as Figure 9 As shown, the locking member 5 has two locking parts 51 spaced apart. The two locking parts 51 surround a clamping groove 52 and clamp the two locking parts 51 on both sides of the connector 103. The locking parts 51 are provided with guide slopes 53. The distance between the two guide slopes 53 gradually increases in the direction away from the clamping groove 52, so that the two locking parts 51 form enlarged guide openings at their ends, thereby guiding the two locking parts 51 to clamp the connector 103 on both sides, so that the connector 103 can be smoothly clamped and locked.

[0073] Specifically, the insertion channel 17 includes a locking section and a connecting section. The locking section is disposed in the locking groove 18, and a fixing plate is disposed on each side of the locking section. The fixing plate is connected between two opposite side walls of the locking groove 18. The connecting pipe 103 passes through the two fixing plates, and the two locking parts 51 are clamped on both sides of the connecting pipe 103 in the vertical direction. The connecting section is disposed on the main structure 1 and is used to communicate with the first valve port 12.

[0074] Optionally, one of the sidewalls of the locking groove 18 and the locking member 5 is provided with a guide rail 181, and the other is provided with a sliding groove that slides with the guide rail 181, so as to guide the locking member 5 in and out of the locking groove 18 and ensure the accuracy of the direction of movement of the locking member 5.

[0075] Specifically, in this embodiment, referring to Figure 8 The guide rail 181 is disposed on the side wall of the locking groove 18, and the sliding groove is disposed on the locking member 5; furthermore, there are two guide rails 181 and two sliding grooves spaced apart in the vertical direction. In other embodiments, the guide rail 181 may be disposed on the locking member 5, and the sliding groove may be disposed on the side wall of the locking groove 18.

[0076] Optionally, such as Figure 4 As shown, a second sealing element 19 is provided on the outer wall of the main structure 1. The second sealing element 19 is used to seal the connection between the first liquid outlet channel and the sampling device 200, and to seal the connection between the second liquid outlet channel and the sampling device 200. Specifically, the second sealing element 19 is used to seal the connection between the suction outlet 15 and the first inlet 201, and to seal the connection between the sampling outlet 16 and the second inlet 202, to prevent liquid leakage. In this embodiment, the second sealing element 19 can simultaneously seal the connection between the suction outlet 15 and the first inlet 201 and the connection between the sampling outlet 16 and the second inlet 202. In other embodiments, two second sealing elements 19 may be provided, one of which is used to seal the connection between the suction outlet 15 and the first inlet 201, and the other is used to seal the connection between the sampling outlet 16 and the second inlet 202.

[0077] In addition, this embodiment also provides an endoscope system, including an endoscope 100, a sampling device 200 and the above-mentioned bridge. The bridge is connected between the endoscope 100 and the sampling device 200 and has all the beneficial effects of the bridge, which will not be described in detail here.

[0078] In addition, since the suction end of the suction mechanism is directly connected to the sampling device 200, that is, the vacuum pump tube of the suction end of the suction mechanism is connected to the sampling device 200, rather than to the bridge, the space occupied by the bridge is simplified, making it easier for doctors to hold and operate the endoscope 100, thus improving the comfort and convenience of use.

[0079] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
