[0030] 使用时,通过开启压力采集系统和控制显示系统,通过触摸屏设定实验所需的压力值,开启正压栗1,使液压回路中的压力值到达设定值(通过压力表3可知),将医用止血钳夹持在模拟血管4处,并通过触摸屏记录无损伤止血钳夹持血管的初始牙数,开启负压栗6,由控制单元判断止血钳是否成功阻断模拟血管4中水的流动,并根据报警系统和触摸屏的显示信息来记录阻断牙数和阻断压力值。 When [0030] using the display system and collection system by opening the pressure control, the pressure values ​​required by the touch screen set up an experiment, turn 1 Li pressure, the pressure in the hydraulic circuit reaches the setpoint value (known by the pressure gauge 3 ), the medical hemostatic clamp held at a simulated vessel 4, through a touch screen and no damage hemostatic clamp recording the initial number of teeth of the holding vessel, the negative pressure opening 6 Li, the control unit determines whether the hemostat simulation successfully blocked vessel 4 the flow of water, based on the display information and the alarm system and the touch screen to the recording block number of teeth and the blocking pressure. 医用无损伤止血钳在没有阻断模拟血管4时,蜂鸣器灯亮且间隔鸣叫三声,间隔时间为0.5s ;医用无损伤止血钳在阻断模拟血管4时,蜂鸣器灯亮且不间隔的鸣叫一声。 Medical hemostat no damage in the absence of blocking simulated blood vessels 4, a buzzer, lights and sounds 3 times intervals, the time interval of 0.5s; non-invasive medical hemostat vessel 4 when the analog block, and no buzzer lights interval chirping loudly. 在阻断后,根据需要可设定阻断时间,以验证在止血钳单边受压情况下,是否可能产生脱牙或滑动而造成阻断失效现象,以确保手术过程中安全可靠。 After blocking, the blocking time may be set according to need, to verify that the pressure hemostat unilateral case, whether or tooth extraction may have caused the slide block failure phenomena, to ensure safe and reliable during operation. 例如当对lOKpa〜26Kpa的模拟血管4进行检测时,开启正压栗1,由于第一电磁阀2及第三电磁阀7是常开电磁阀,水从储液罐8栗向液压回路,以驱除管道内的气体,等到气体完全驱除后,关闭第三电磁阀7给管道回路加压,使模拟血管4内的压力上升至设定值,关闭正压栗1、第一电磁阀2及第三电磁阀7。 For example, when the analog detecting lOKpa~26Kpa vessel 4, opening the positive pressure 1 Li, since the first solenoid valve 2 and the third electromagnetic valve 7 is a normally open solenoid valve, water from the reservoir to the hydraulic circuit 8 Li, to a purge gas conduit, until the gas is completely purge, the third electromagnetic valve 7 to the closed circuit pressurized conduit, the pressure in the blood vessels of the analog 4 rises to a set value, pressure off Li 1, the first solenoid valve and the second 2 three solenoid valves 7. 利用止血钳夹持模拟血管4,通过控制显示系统中的触摸屏手动记录止血钳当前夹持所在的棘齿数。 Using analog hemostatic clamp holding vessel 4, through manual control of the touch screen display system records the ratchet teeth hemostat clamp currently located. 通过报警系统判断此时止血钳是否阻断模拟血管4内水。 At this time the alarm system is determined by whether the blocking hemostat 4 Simulation water vessel. 若没发生阻断,则继续增加止血钳的棘齿挡位直至阻断;若阻断已发生,则实验完毕,当前触摸屏上记录的棘齿数即为该止血钳阻断模拟血管4的棘齿数。 If no blocking occurs, continue to increase the hemostat until the ratchet gear block; if the block has occurred, the test is completed, the current record on the touch screen is the number of teeth of the ratchet block hemostat simulated blood vessels of the ratchet teeth 4 . 第二电磁阀5是常闭电磁阀,当通过报警系统已判断止血钳成功阻断模拟血管后,开启负压栗6同时开启第二电磁阀5,回抽管道内水,判断有无泄漏。 The second solenoid valve 5 is normally closed electromagnetic valve, when the alarm system is determined by successful blocking hemostat simulated blood vessels, while the opening 6 Li suction opening the second solenoid valve 5, the tap water Withdrawing determining leaks. 当对5Kpa〜lOKpa的模拟血管4进行检测时,开启正压栗1的同时开启第二电磁阀5,步骤与lOKpa〜26Kpa时相同) When detecting a mock vessel 5Kpa~lOKpa 4, Li 1 open pressure opening while the second solenoid valve 5, the same as if the lOKpa~26Kpa)

[0031] 因此,本发明是一种快速、准确的对医用无损伤止血钳进行阻断检测的装置,可以解决医用无损伤止血钳临界阻断点定性定量分析的问题,提高了手术过程中医用无损伤止血钳使用的安全性,避免人为测试的误判以及检测成本过大,测试速度快,测试结果准确,省时省力,大大提高了医生在手术过程中的准确性,降低和减少血管损伤,提高手术的安全性。 [0031] Accordingly, the present invention is a fast and accurate for non-invasive medical hemostatic forceps blocking detection apparatus can be solved without damage hemostat critical medical blocking point qualitative and quantitative analysis of the problem, to improve the surgical procedure used in traditional Chinese no damage hemostatic forceps use of security to avoid human misjudgment and detection test cost is too large, fast test speed, accurate test results, saving time and effort, greatly improving the accuracy of the doctor during surgery, reducing and reducing blood vessel damage to improve the safety of surgery.
