实施例2Example 2
为了提高实用性，本实施例在实施例1的基础上做了进一步地设置。In order to improve practicality, this embodiment makes further arrangements based on Embodiment 1.
在本实施例中，套管1的前端两侧分别设置有保护板，保护板为套管1前部挖去两个U形槽之后所留下的两个凸起。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 .
在本实施例中，冷却腔8内填充有冷却液。In this embodiment, the cooling chamber 8 is filled with cooling liquid.
具体实施时，在冷却腔8上设置有冷却液进水口、冷却液出水口及冷却液循环机构，增大换热效率。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.
在本实施例中，进水管2包括：In this embodiment, the water inlet pipe 2 includes:
第一进水管，第一进水管的第一端贯穿冷却腔8并与外接水源连通；A first water inlet pipe, a first end of which passes through the cooling chamber 8 and is connected to an external water source;
第二进水管，第二进水管的第一端与出水口4连通；A second water inlet pipe, a first end of the second water inlet pipe is connected to the water outlet 4;
水量调节机构3，水量调节机构3的第一端与第一进水管的第二端连通，水量调节机构3的第二端与第二进水管的第二端连通。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.
在本实施例中，第二进水管包括：In this embodiment, the second water inlet pipe includes:
并排设置的加速进水管21与减速进水管22，加速进水管21的第一端与减速进水管22的第一端均与出水口4连通，加速进水管21的第二端与减速进水管22的第二端均与水量调节机构3连通，加速进水管21用于增大进水的流速，减速进水管22用于减小进水的流速。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.
在本实施例中，加速进水管21内呈渐缩式结构，且加速进水管21周向设置有与其连通的螺旋通道，螺旋通道的切口位于远离加速进水管21中心的一侧，螺旋通道沿加速进水管21的轴向螺旋延伸，通过渐缩式结构的喷射口，又具有可以增加喷射速度的螺旋加速通道，在输出压力相同的情况下，能够加大水的喷出速度，增加喷射距离。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.
在本实施例中，减速进水管22包括依次连通的第一减速进水管221、第二减速进水管222及第三减速进水管223，第一减速进水管221为特斯拉阀结构，第二减速进水管222为弯曲通道，第三减速进水管223为渐扩式结构。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.
当水进入第一减速进水管后会分流，一路顺着主通道，另一路则会流入环形通道，最后再次与主通道相会合，在流体会合过程中，因为流向不同相互碰撞，从而对主通道流体产生阻力，逐渐降低流体的速度。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.
再经过第二减速进水管222、第三减速进水管223逐级降低水流速度。Then the water flow velocity is gradually reduced through the second deceleration water inlet pipe 222 and the third deceleration water inlet pipe 223 .
本发明通过设置的减速进水管与加速进水管，在遇到难清洗的时候选择加速通道进行强度清洗，不需要强度清洗时，通过减速通道延长了水与冷却液的接触时间，进一步将水进行冷却，冷却的更加充分，而且慢速水可以避免床单潮湿、污染手术区。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.
在本实施例中，水量调节机构3包括：In this embodiment, the water volume regulating mechanism 3 includes:
壳体，壳体的第一端与第一进水管的第二端连通，第二端与第二进水管的第二端连通；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;
切换板31，切换板31可转动地设置于壳体内，用于在第一减速进水管221、第二减速进水管222之间的切换；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;
转换把手32，转换把手32设置于套管1的外侧，转换把手32与切换板31固定连接。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 .
在本实施例中，负压吸水管5上至少部分设置为特斯拉阀结构，负压吸水管5的第一端与吸水口6连通，负压吸水管5的第二端与抽吸装置连接。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.
具体实施时，微波传导线9、进水管2以及负压吸水管依次穿过刀杆和手柄并最终与对应的能源装置或驱动装置连接。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.
在本实施例中，出水口4到微波刀7尖端之间的垂直距离小于吸水口6到微波刀7尖端之间的垂直距离，从而便于及时将血水通过吸水口6抽离。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.
在本实施例中，冷却腔8的一侧设置有微波传导线9，微波刀7与微波传导线9电连接。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 .
具体实施时，微波传导线9为带有绝缘外皮的铜线。During specific implementation, the microwave transmission line 9 is a copper wire with an insulating sheath.
使用方法：接通电源后，医务人员手持把手，将微波刀7对准病变部位，微波刀7开始工作，医务人员根据组织清理的难易程度，当较难清理时，逆时针转动转换把手32，带动切换板31堵住减速进水管22的进水端，使水经加速进水管进行加速，对组织进行强度清洗；当不难清理时，顺时针转动转换把手32，带动切换板31堵住加速进水管21的进水端，使水更加充分地与冷却液接触，进行热交换，冷却更加充分的同时，降低水流速度，可以避免床单潮湿、污染手术区。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.
