Embodiment 1
[0027] The energized wire 45 is wound counterclockwise on the energized solenoid 41. When the power supply 1 is switched on, a current is generated in the energized wire 45. At this time, the upper end of the energized solenoid 41 is an N pole, and the lower end is an S pole. Therefore, the energized solenoid 41 The line pipe 41 and the magnet 42 attract each other, and the insulating baffle 44 remains under the switch 2; the circuit current controller 3 can be adjusted to the maximum resistance before the knot is tied, so that the attractive force between the electrified solenoid 41 and the magnet 42 At this time, only a little pulling force can pull up the magnet 42 to make the luminous reminder 5 luminous. In the process of practicing knotting, the resistance value of the circuit current controller 3 can be gradually reduced, that is, the pulling force generated during knotting should be as small as possible, thereby increasing the difficulty of knotting. By adjusting the c...

The invention discloses a device for surgical tensionless knotting. The device comprises a knotting circuit, a luminous reminding circuit, a shell and a deep knotting cylinder, wherein the knotting circuit is fixed in the shell; the deep knotting cylinder is arranged above the shell and is communicated with the shell; the knotting circuit comprises a power supply, a switch, a circuit current controller and a hooking control device; the positive electrode of the power supply is connected with one end of the switch and is simultaneously connected with one end of the hooking controller; the other end of the hooking controller is connected with one end of the circuit current controller; the other end of the circuit current controller is connected with the negative electrode of the power supply; the luminous reminding circuit comprises a luminous reminder of which the positive electrode is connected with the other end of the switch and the negative electrode is connected with the negative electrode of the power supply; and the luminous reminder and the circuit current controller are arranged outside the shell. In the device, on and off of the switch are controlled by using attraction of an electrified solenoid and a magnet and amplitude of knotting tension, so that overlarge force of knotting can be reminded for a user through light.
Description
technical field [0001] The invention relates to a knotting device, in particular to a device for tension-free knotting in surgery. Background technique [0002] At present, the commonly used surgical deep knotting teaching apparatus is composed of a cylindrical transparent plastic knotting tube and a knotting hook, and the deep knotting of the deep, abdomen and pelvic cavity is simulated according to the size and depth of the cylindrical knotting tube. However, in deep knotting in clinical surgery, in order to avoid damage to deep tissues during knotting, it is also necessary to pay attention to the principle of "no tension", and the existing surgical deep knotting models cannot satisfy deep tension-free knotting. requirements. [0003] A prior art patent No. CN2075066U is a medical steel wire tightening knotter, which includes a handle and a guide wire tube connected with the handle. On the tube wall of the guide wire tube, 2-5 connected and The "a"-shaped hole communicat...
