所述的喷头组件，外管，内管分别采用塑料一体成型；所述手柄组件由左右两个对称的半体固定连接构成；所述的手柄体前端成型有与所述外管配合的外管连接套311；所述的外管套接在所述外管连接套上；所述的吸引管前端成型有与所述内管配合的第二内管连接套352；所述的内管套接在所述第二内管连接套上；所述的排水管外壁后端成型有等距离分布的多个卡圈321。 The nozzle assembly, the outer tube, and the inner tube are integrally formed of plastic; the handle assembly is composed of two symmetrical halves fixedly connected; the front end of the handle body is formed with an outer tube that matches the outer tube Connecting sleeve 311; the outer tube is sleeved on the outer tube connecting sleeve; the front end of the suction tube is formed with a second inner tube connecting sleeve 352 matched with the inner tube; the inner tube is sleeved On the second inner pipe connecting sleeve; the rear end of the outer wall of the drain pipe is formed with a plurality of collars 321 distributed equidistantly.
所述第一阀门连接有水管，所述水管上串连有电磁阀，所述电磁阀与控制器电连接，所述控制器控制电磁阀循环导通、截止：导通0.3～0.5s，截止0.3～0.5s。 The first valve is connected to a water pipe, and a solenoid valve is connected in series on the water pipe. The solenoid valve is electrically connected to a controller, and the controller controls the solenoid valve to be turned on and off in a cycle: conduction 0.3-0.5s, cutoff 0.3～0.5s.
通过电磁阀控制水流间断性导通，使得从环形喷水口喷出的水形成脉冲式的锥形水帘，相比持续的喷水刷洗效果没有明显区别，但出水量减少40%以上，使得内管能够及时地将绝大部分水吸走，缩短手术时间，减少患者痛苦。 The intermittent conduction of the water flow is controlled by the solenoid valve, so that the water sprayed from the annular water nozzle forms a pulsed cone-shaped water curtain. Compared with the continuous water spray scrubbing effect, there is no obvious difference, but the water output is reduced by more than 40%. The inner tube can absorb most of the water in a timely manner, shortening the operation time and reducing the pain of the patient.
所述环形喷水口内周壁面的端部切线方向与喷头组件轴向之间形成30～35度的夹角，所述环形喷水口外周壁面切线方向与喷头组件轴向之间形成的夹角比环形喷水口内周壁面的端部切线方向与喷头组件轴向之间形成的夹角大3～5度；所述环形喷水口内周壁面的端部与外周壁面的端部之间的间距为0.3～1.5mm。 An included angle of 30 to 35 degrees is formed between the tangential direction of the end of the inner peripheral wall of the annular water spout and the axial direction of the nozzle assembly, and the angle formed between the tangential direction of the outer peripheral wall of the annular water spout and the axial direction of the nozzle assembly 3 to 5 degrees greater than the angle formed between the tangential direction of the end of the inner peripheral wall of the annular water nozzle and the axial direction of the nozzle assembly; the distance between the end of the inner peripheral wall of the annular water nozzle and the end of the outer peripheral wall 0.3 ~ 1.5mm.
该环形喷水口的设计使得冲洗部位附近的污物被冲到环形喷水孔中间的位置，利于内管利用负压及时将血水及其它污物及时吸走，冲洗效果好。 The design of the annular water spray port enables the dirt near the flushing part to be flushed to the middle of the annular water spray hole, which is beneficial for the inner tube to absorb blood and other dirt in time by using the negative pressure, and the flushing effect is good.
