Embodiment 1
[0042] The energization wire 45 is wound on the energization solenoid 41 counterclockwise. When the power supply 1 is turned on, a current is generated in the energization wire 45. At this time, the upper end of the energization solenoid 41 is the N pole, and the lower end is the S pole, so the energization screw The wire tube 41 and the magnet 42 attract each other, and the insulating baffle 44 is kept under the switch 2; the user can go deep into the knotting cylinder 7 and practice knotting on the knotting hook 43. When the knotting force is too large, When the pulling force generated by the knot is greater than the attractive force between the magnet 42 and the energized solenoid 41, the magnet 42 is pulled up, and at the same time, the insulating baffle 44 is lifted upward, and one end of the insulating baffle 44 switches the switch 2. closed, the light-emitting reminder circuit is turned on, so that the light-emitting reminder 5 emits light, reminding the user that the kn...

The invention relates to a detection method of a device for surgical tension-free knotting. The method at least comprises the following steps of: 1, sequentially connecting power supply, a switch, a tick control device and a circuit current controller to form a tick circuit; 2, sequentially connecting the power supply, the switch and an illumination reminder to form an illumination reminding circuit; 3, putting a line for knotting into the bottom of a knotting tube, and knotting on a knotting hook; and 4, judging whether the knotting is succeed according to illumination condition of the illumination reminder, if the illumination reminder gives out the light, determining that the knotting is failure, otherwise determining that the knotting is succeed. According to the method, the switching on and the switching off of the switch in the illumination reminding circuit are controlled by attractive force between an energized solenoid and a magnet and the size of tensile force during knotting, and the brightness of the illumination reminder is used for judging whether the knotting is succeed. The method is convenient to operate, and the device is low in cost, easy to promote and apply, and particularly suitable for a doctor to practice knotting.
Description
technical field [0001] The invention relates to a detection method of a knotted circuit, in particular to a detection method of a device used for surgical tension-free knotting. Background technique [0002] At present, the commonly used surgical deep knotting teaching instrument is composed of a cylindrical transparent plastic knotting tube and a knotting hook. According to the adjustment of the size and depth of the cylindrical knotting tube, the deep knotting of the deep, abdominal and pelvic cavity is simulated. However, for deep knotting in clinical surgical operations, in order to avoid damage to deep tissues during knotting, it is necessary to pay attention to the principle of "no tension", and the existing surgical deep knotting model cannot satisfy deep tension free knotting requirements. [0003] A medical wire tensioning and knotting device with a patent number of CN2075066U in the prior art includes a handle, a wire guide tube connected with the handle, and 2-5 ...
