Therefore, they should not be construed as limitations on this application.

[0026] The following describes preferred embodiments of the utility model in combination with the drawings. Embodiment one:

[0027] As Figure 1 , Figure 2 , the utility model provides a kind of auxiliary suction device for radio frequency electrode, radio frequency electrode includes insulated handle and insulating tube 14, the bottom end of insulating tube 14 is equipped with electrode contact 9, electrode contact 9 can generate heat by high-frequency current to carry out hemostasis to bleeding point.Electrically insulated handle includes stationary part 1 and movable part 2 that are slidably matched, and spring exists between stationary part 1 and movable part 2, the top end of insulating tube 14 is fixedly connected after passing through movable part 2 with stationary part 1, and insulating tube 14 is slidably matched with movable part 2.Sleeve 8 is also fixedly installed at the bottom end of movable part 2, and insulating tube 14 is slidably installed in sleeve 8.Movable part 2 is also hingedly connected with the middle part of first handle 3, and stationary part 1 is hingedly connected with the middle part of second handle 4, and the top end of first handle 3 is hingedly connected with the top end of second handle 4, and the bottom end of first handle 3 and second handle 4 extends downward to form a handle.Electrically insulated handle, sleeve 8, insulating tube 14 and electrode contact 9 all belong to prior art, and will not be described in detail here.

[0028] Suction tube 6 is also sleeved on the outside of sleeve 8, the top end of suction tube 6 is sealed, and the bottom end is open, and annular channel is formed between the inner wall of suction tube 6 and the outer wall of sleeve 8, and the upper part of suction tube 6 is communicated with external suction device.Suction device is a commonly used medical instrument, which is a container for sucking out bleeding during operation, and belongs to conventional prior art, and will not be described in detail here.

[0029] The top end of straight connecting pipe 5 is fixedly connected and communicated with the top end of sleeve 8, and the bottom end of suction tube 6 is located above the bottom end of sleeve 8, and bypass joint 12 is also fixedly installed and communicated on straight connecting pipe 5, and the end of bypass joint 12 away from straight connecting pipe 5 is detachably installed with sealing cap 13.Sealing cap 13 is provided with internal thread, and the end of bypass joint 12 close to sealing cap 13 is provided with external thread, and detachable connection is realized by thread cooperation, when the device needs to be used, only sealing cap 13 is twisted down, and then suction device is communicated at the end of bypass joint 12 away from straight connecting pipe 5, when it is not needed, the connecting device of suction device is removed, and sealing cap 13 is reinstalled on bypass joint 12, so that straight connecting pipe 8 can be prevented from being contaminated.

[0030] As Figure 3 shown, in order to prevent negative pressure suction device from leaking when working, sealing gasket 10 is also installed between straight connecting pipe 5 and sleeve 8.

[0031] As Figure 1 , Figure 3 , Figure 4As shown, the suction pipe 6 is a hose, and the inner side of the suction pipe 6 is provided with a plurality of support beads 7, and the inner side of the support bead 7 abuts against the sleeve 8. Specifically, the support beads 7 are distributed in a circumferential array on the inner side of the first suction pipe 6 and are distributed in a linear array along the axial direction of the first suction pipe 6, and any two support beads 7 are not attached to each other. The distribution of the support beads 7 is to ensure that the suction device will not be attached to the sleeve 8 during operation, preventing the flow channel of the liquid from being blocked, and to ensure that the suction device can normally suck, preventing it from only sucking between two long straight support beads 7.

[0032] As a further description of the present example, the included angle between the bypass joint 12 and the direct connection pipe 5 is 45°. Compared with the installation of the suction device at an angle of 90° or obtuse angle, the installation at an acute angle makes the liquid suction process more smooth, and the smaller the included angle, the better the suction process. However, considering the installation position of the suction device, in order to make the insulating handle not affect the suction device, an included angle of 45° is adopted in the present embodiment.

[0034] The direct arrangement of the suction pipe 6 makes the structure of the device simpler, cheaper and reduces the economic burden.

[0035] The suction device has a suction port and a discharge port, and all the above-mentioned communication with the suction device is communicated with the suction port of the suction device, which mainly functions to generate negative pressure in the suction pipe 6 and then suck the blood mist out along the suction pipe 6.

[0036] The working principle of the device is as follows: when the radio frequency electrode is in the process of stopping bleeding, the endoscope is affected by the blood mist to make the vision blurred, the suction device is opened, at this time the blood mist will flow out along the suction pipe 6, thereby ensuring the clarity of the endoscope vision.

[0037] In summary, the auxiliary suction device for radio frequency electrode uses the arrangement of the suction pipe, and connects the suction pipe 6 with the negative pressure suction device, when facing the generation of blood mist, the blood mist can be directly sucked out through the suction pipe 6, thereby ensuring the clarity of the endoscope vision, avoiding the occurrence of the phenomenon of misinjury of nerves caused by blurred vision, and improving the accuracy of hemostasis. The structure of the device is simple, cheap and convenient to produce.

[0038] The above merely is the preferred implementation form of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
