DETAILED DESCRIPTION

[0032] Example 1

[0033] refer to Figure 1-Figure 2 , a water-cooled cutting surface self-cleaning microwave hemostatic surgical knife head, comprising:

[0034] A sleeve 1, wherein at least a portion of the sleeve 1 is provided with a cooling chamber 8;

[0035] The microwave knife 7 is arranged at the front end of the sleeve 1 and is used to cauterize the tissue around the incision to stop bleeding. The front end of the microwave knife 7 is provided with a water outlet 4 and a water suction port 6;

[0036] A water inlet pipe 2, at least part of which is disposed in the cooling chamber 8 and communicated with the water outlet 4, for flushing the tissue;

[0037] The negative pressure water suction pipe 5 is arranged at one side of the cooling chamber 8 and is connected with the water suction port 6 for sucking away blood.

[0038] The present invention provides a water outlet and a water suction port, so that when a microwave hemostatic knife is used for surgery, water can be discharged from the water outlet to flush the tissue, and blood can be sucked out through the water outlet, thereby providing a clear field of vision for the surgery.

[0039] Example 2

[0040] In order to improve practicality, this embodiment makes further arrangements based on Embodiment 1.

[0041] In this embodiment, protection plates are respectively provided on both sides of the front end of the sleeve 1 , and the protection plates are two protrusions left after two U-shaped grooves are dug out from the front of the sleeve 1 .

[0042] In this embodiment, the cooling chamber 8 is filled with cooling liquid.

[0043] During specific implementation, a coolant inlet, a coolant outlet and a coolant circulation mechanism are provided on the cooling chamber 8 to increase the heat exchange efficiency.

[0044] In this embodiment, the water inlet pipe 2 includes:

[0045] A first water inlet pipe, a first end of which passes through the cooling chamber 8 and is connected to an external water source;

[0046] A second water inlet pipe, a first end of the second water inlet pipe is connected to the water outlet 4;

[0047] The water volume regulating mechanism 3 has a first end connected to the second end of the first water inlet pipe, and a second end connected to the second end of the second water inlet pipe.

[0048] In this embodiment, the second water inlet pipe includes:

[0049] The accelerating water inlet pipe 21 and the decelerating water inlet pipe 22 are arranged side by side, and the first end of the accelerating water inlet pipe 21 and the first end of the decelerating water inlet pipe 22 are both connected to the water outlet 4, and the second end of the accelerating water inlet pipe 21 and the second end of the decelerating water inlet pipe 22 are both connected to the water volume regulating mechanism 3. The accelerating water inlet pipe 21 is used to increase the flow rate of the incoming water, and the decelerating water inlet pipe 22 is used to reduce the flow rate of the incoming water.

[0050] In this embodiment, the accelerating water inlet pipe 21 has a tapered structure, and a spiral channel connected to the accelerating water inlet pipe 21 is circumferentially arranged. The cutout of the spiral channel is located on a side away from the center of the accelerating water inlet pipe 21. The spiral channel extends in an axial spiral along the accelerating water inlet pipe 21. The injection port of the tapered structure has a spiral accelerating channel that can increase the injection speed. Under the condition of the same output pressure, the water spray speed can be increased and the injection distance can be increased.

[0051] In this embodiment, the deceleration water inlet pipe 22 includes a first deceleration water inlet pipe 221, a second deceleration water inlet pipe 222 and a third deceleration water inlet pipe 223 which are connected in sequence. The first deceleration water inlet pipe 221 is a Tesla valve structure, the second deceleration water inlet pipe 222 is a curved channel, and the third deceleration water inlet pipe 223 is a gradually expanding structure.

[0052] When water enters the first deceleration water inlet pipe, it will be split into two paths, one path will follow the main channel, and the other path will flow into the annular channel, and finally meet with the main channel again. During the fluid merging process, due to different flow directions, they collide with each other, thereby generating resistance to the fluid in the main channel and gradually reducing the speed of the fluid.

[0053] Then the water flow velocity is gradually reduced through the second deceleration water inlet pipe 222 and the third deceleration water inlet pipe 223 .

[0054] The present invention provides a decelerating water inlet pipe and an accelerating water inlet pipe. When cleaning is difficult, the accelerating channel is selected for intensive cleaning. When intensive cleaning is not required, the contact time between water and coolant is prolonged through the decelerating channel, and the water is further cooled, so that the cooling is more sufficient. Moreover, the slow water can prevent the bed sheets from getting wet and contaminating the operating area.

[0055] In this embodiment, the water volume regulating mechanism 3 includes:

[0056] A shell, wherein a first end of the shell is connected to a second end of the first water inlet pipe, and a second end of the shell is connected to a second end of the second water inlet pipe;

[0057] A switching plate 31, which is rotatably disposed in the housing and is used for switching between the first deceleration water inlet pipe 221 and the second deceleration water inlet pipe 222;

[0058] The conversion handle 32 is arranged on the outside of the sleeve 1 , and the conversion handle 32 is fixedly connected to the switching plate 31 .

[0059] In this embodiment, at least a portion of the negative pressure water suction pipe 5 is provided with a Tesla valve structure, a first end of the negative pressure water suction pipe 5 is communicated with the water suction port 6, and a second end of the negative pressure water suction pipe 5 is connected to the suction device.

[0060] During specific implementation, the microwave transmission line 9, the water inlet pipe 2 and the negative pressure water suction pipe pass through the knife rod and the handle in sequence and are finally connected to the corresponding energy device or driving device.

[0061] In this embodiment, the vertical distance between the water outlet 4 and the tip of the microwave knife 7 is smaller than the vertical distance between the water suction port 6 and the tip of the microwave knife 7, thereby facilitating timely extraction of blood through the water suction port 6.

[0062] In this embodiment, a microwave transmission line 9 is provided on one side of the cooling cavity 8 , and the microwave knife 7 is electrically connected to the microwave transmission line 9 .

[0063] During specific implementation, the microwave transmission line 9 is a copper wire with an insulating sheath.

[0064] Instructions for use: After the power is turned on, the medical staff holds the handle and aims the microwave knife 7 at the lesion site, and the microwave knife 7 starts to work. The medical staff turns the conversion handle 32 counterclockwise according to the difficulty of tissue cleaning. When it is difficult to clean, the medical staff drives the switching plate 31 to block the water inlet end of the deceleration water inlet pipe 22, so that the water is accelerated through the acceleration water inlet pipe to perform intensive cleaning on the tissue; when it is not difficult to clean, the medical staff turns the conversion handle 32 clockwise to drive the switching plate 31 to block the water inlet end of the acceleration water inlet pipe 21, so that the water is more fully in contact with the coolant for heat exchange. While cooling more fully, the water flow rate is reduced to avoid the sheets from getting wet and contaminating the surgical area.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
