Furthermore, the descriptions of each embodiment below have their own specific focus. For details not provided in one embodiment, please refer to the relevant descriptions of other embodiments.

[0034] To address the technical problem in the prior art that clamp devices lack a water flushing function during surgery, which prevents doctors from accurately determining the location of bleeding lesions, one embodiment of the present application provides a water-spraying clamp device, which is described in detail below.

[0035] like Figures 1 to 4 As shown, a water spraying clamp device includes

[0036] The double-lumen tube 1 includes a first channel 11 and a second channel. The first channel 11 is suitable for water injection. The rear end of the first channel 11 is sealed. A spring tube 12 is fixedly installed in the second channel. A cable 8 is passed through the spring tube 12.

[0037] A three-way connector 2, the rear end of the double-lumen tube 1 is inserted from the first interface of the three-way connector 2 and passes through the second interface. A side hole is provided on the side wall of the first channel 11 to connect the first channel 11 with the third interface of the three-way connector 2. The three-way connector 2 is sealed against the outer wall of the double-lumen tube 1. The second interface of the three-way connector 2 is connected to the handle assembly 3;

[0038] A clip assembly 5, which is arranged at the front end of the second channel;

[0039] The front end of the cable 8 is connected to the clamp assembly 5, and the rear end thereof passes through the spring tube 12 and is connected to the slip ring 32 in the handle assembly 3. The slip ring 32 is suitable for driving the clamp in the clamp assembly 5 to perform a clamping movement through the cable 8.

[0040] When injecting water, the syringe 6 is connected to the third interface of the three-way connector 2.

[0041] Specifically, as an optional implementation in this embodiment, Figure 1 and Figure 2 As shown, a connecting seat 4 is provided at the front end of the spring tube 12, and the connecting seat 4 extends out of the second channel;

[0042] The clamp assembly 5 includes a clamp seat 52 and a pair of clips 51. The rear end of the clamp seat 52 forms a protrusion, and the rear end of the connecting seat 4 is provided with a groove. The clamp seat 52 is inserted into the groove through the protrusion to assemble the clamp seat 52 and the connecting seat 4 together. The clamp seat 52 is suitable for rotating on the connecting seat 4.

[0043] In this embodiment, the connecting seat 4 and the spring tube 12 are both metal parts, and the two are connected by welding. Figure 2 As shown, the connecting seat 4 extends from the front end of the second channel of the double-lumen tube 1.

[0044] The clamp assembly 5 is an existing product. The rear ends of the two clamps 51 are connected to the cable 8. The cable 8 can drive the clamps 51 to retract into the clamp seat 52 by pulling the clamps 51 backward, thereby clamping the tissue.

[0045] The clamping seat 52 is a metal sheet, which forms an axial assembly with the connecting seat 4. The clamping seat 52 can be rotated left at the front end of the connecting seat 4. When the cable 8 is released, the clamping seat 52 can be removed from the front end of the connecting seat 4.

[0046] Specifically, as an optional implementation in this embodiment, Figure 1 and Figure 2 As shown, a rotary head 7 is provided between the second channel and the handle assembly 3 , the rotary head 7 is fixedly connected to the three-way joint 2 , and the rotary head 7 and the handle assembly 3 are rotationally matched.

[0047] The turret 7 is clamped with the core rod 31 , and a clamping ring is formed on the turret 7 . The clamping ring is located inside the core rod 31 . The clamping ring limits the turret 7 from moving axially relative to the core rod 31 , but does not limit the turret 7 from rotating relative to the core rod 31 .

[0048] Specifically, as an optional implementation in this embodiment, Figure 1 and Figure 2 As shown, the handle assembly 3 includes a core rod 31 and a slip ring 32 , and the slip ring 32 is connected to the cable 8 .

[0049] Specifically, as an optional implementation in this embodiment, Figure 3 As shown, the rear end of the first channel 11 is sealed with glue 13.

[0050] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, the cross section of the first channel 11 is C-shaped, and the cross section of the second channel is circular.

[0051] How to use the water spray clamp device:

[0052] 1. Instrument insertion: Gently pull the slip ring 32 to close the clip 51, insert the product into the endoscope channel, and then gradually push the product through the endoscope channel at a length of 2 to 3 mm. Observe through the endoscope until the clip 51 and the clamp seat 52 are completely exposed from the endoscope channel.

[0053] 2. Flushing operation: After the product reaches the lesion site, connect the syringe 6, and water enters the first channel 11 of the double-lumen tube 1 through the water inlet of the three-way connector 2, and finally sprays out from the front water outlet of the first channel 11 to flush the lesion site.

[0054] 3. Clamping operation: After the product reaches the lesion location, push the slip ring 32 to open the clamp 51, gently turn the rotating head 7 to rotate the clamp 51 to a suitable angle to clamp the lesion, and gently pull the slip ring 32 under endoscopic observation to close the clamp 51 and clamp the tissue. Evaluate whether the clamping position is ideal. If the clamping position needs to be changed, gently push the slip ring 32 to reopen the clamp 51, reposition and clamp the tissue. If there is no need to change the clamping position, continue with the release operation.

[0055] 3. Release operation: After the clamp 51 closes and clamps the tissue, continue to pull the slip ring 32. You will feel the pulling force of the handle becoming stronger and stronger until you hear a "click" sound. The pulling force of the slip ring 32 suddenly disappears, and the slip ring 32 will be pulled to the end of the handle under the action of inertia.

[0056] 4. Instrument withdrawal: If the clamp assembly 5 does not need to be released, the slip ring 32 can be pulled to close the clip 51, and then the product can be withdrawn from the endoscope channel. If the clamp assembly 5 has been released, the delivery device can be directly withdrawn.
