具体实施方式 detailed description

[0012] 下面将结合附图和具体实施例对本发明进行进一步详细说明。 [0012] The accompanying drawings and the following specific embodiments of the present invention will be described in further detail.

[0013] —种校准式腹腔镜用取路卡,其结构如图1所示,包括穿刺鞘1、管芯2、手持板7以及安全校准装置4,管芯2设置在穿刺鞘1中心,能够在外力作用下对皮肤进行穿刺;手持板7配装在穿刺鞘1的顶端,方便医护人员手持;安全校准装置4设置在管芯底端的穿刺鞘上,用于控制医护人员穿刺的行进量,起到校准作用。 [0013] - kind of calibration with laparoscopic take roadblocks, the structure shown in Figure 1, including puncture sheath 1, die 2, 7, and handheld security device calibration plate 4, the die 2 is provided in the center of the puncture sheath 1, the external force can puncture the skin; holding plate 7 is fitted in the tip of the puncture sheath 1, to facilitate medical handheld; calibration safety device 4 is provided on the bottom of the die puncture sheath puncture is used to control the amount of travel medical , play a role in the calibration.

[0014] 本发明中,安全校准装置为柱体定位块,柱体定位块的中心设置有穿过穿刺鞘的通孔,柱体定位块通孔的内壁上设置有内螺纹,穿刺鞘1下部的外壁上设置有与柱体定位块的通孔相配装的外螺纹5。 Through holes [0014] of the present invention, the safety device is calibrated cylinder positioning block, the center column positioning block is provided with a puncture through the sheath is provided with an inner wall of the cylinder block positioned internally threaded through holes, the lower part of the puncture sheath 1 the outer wall is provided with an external thread 5 and the cylinder block through positioning holes filled match.

[0015] 本发明使用时,将柱体定位块的底端面贴紧患者皮肤,然后拿手持板,旋转穿刺鞘,即可进行腹壁穿刺操作。 [0015] When the present invention, the bottom surface of the cylinder block snapping positioning the patient's skin, and then take the hand plate, rotating sheath puncture, abdominal puncture operation can be carried out. 操作过程中,能够将直接施加皮肤上的垂直力度转换为旋转过程中的旋转力,将管芯行进的步距缩短了一个穿刺鞘圆周,因此给医护人员在刺破皮肤的瞬间留足了反应的时间,有效防止了取路卡对腹腔内脏器和血管损伤现象的发生。 During operation, the vertical force can be applied directly on the skin during rotation is converted to rotational force, the die travels stride shortens a puncture sheath circumference, so to pierce the skin of health care workers in an instant leave enough reaction the time taken to effectively prevent the occurrence of roadblocks abdominal visceral and vascular injury phenomenon.

[0016] 为使医护人员在管芯底端穿破皮肤时明显地感受到压力的变化,本实施例中,在手持板7与管芯顶端之间设置了弹簧3。 [0016] In order to make health care workers clearly feel the bottom of the die puncture the skin when pressure changes, in this embodiment, between 7 and the die top plate holding spring 3 is provided. 在医护人员进行穿刺过程中,弹簧随着旋拧的不断压缩,当管芯刺破皮肤时,管芯快速进入腹腔,弹簧失去皮肤的阻力而瞬间释放,使得医护人员能够明显感受到压力的变化,而停止穿刺操作。 In the medical puncture during spring with continuous compression screwing, when the die pierce the skin, die quickly into the abdominal cavity, the resistance of the skin to lose spring instantaneous release, so health care workers can obviously feel the pressure change , stop puncture operation.

[0017] 为更进一步地直观提醒医护人员管芯底端穿破皮肤,本发明在手持板上还设置了报警模块,用于管芯在穿破皮肤时发出报警信号,及时对医护人员进行提醒。 [0017] To further visualize remind health care workers die at the bottom of puncture the skin, in the present invention is a handheld board also set up an alarm module for die an alarm signal when the puncture the skin, in a timely manner to remind the medical staff . 本实施例中,报警模块的结构如图2所示,包括单片机、触发电路、蜂鸣器6以及压力传感器,蜂鸣器6设置在穿刺鞘的外壁上;压力传感器设置在手持板中心,并与弹簧的顶端相对应,用于感知压力的变化;压力传感器的输出端连接单片机的输入端,用于将感知的压力信息传输给单片机,单片机对压力信号的变化进行分析;单片机的输出端连接触发电路的输入端,当单片机分析到压力在逐步增加的过程中突然变小时,向触发电路发出触发导通信号;触发电路接通蜂鸣器回路,蜂鸣器报警,对医护人员起到及时提醒作用。 In this embodiment, the alarm module structure shown in Figure 2, includes a microcontroller, trigger circuit, the buzzer 6 and a pressure sensor, the buzzer 6 is disposed on the outer wall of the needle sheath; a pressure sensor is provided in the handheld center of the plate, and corresponding to the top of the spring for sensing pressure changes; the output of the pressure sensor is connected to the input of the microcontroller for transmission of information, perceived pressure to the microcontroller, the microcontroller to change the pressure signal is analyzed; the output of the microcontroller is connected trigger input of the circuit, when the microcontroller to analyze the process of gradually increasing the pressure suddenly becomes small, a trigger turn-on signal to the trigger circuit; the flip-flop circuit switched buzzer, the buzzer alarm, the medical staff to play in time reminder.
