Problems solved by technology
[0002] The current surgery is generally knotted by hand. For the operation of obesity, deep incision and difficult to expose, it is very difficult to perform tissue ligation, which affects the accuracy and speed of ligation, especially in laparoscopic surgery.
Sometimes it is done by enlarging the incision or using silver or titanium clips, but enlarging the incision increases the damage and aggravates the pain of the patient; using silver or titanium clips not only has high cost, but also makes the metal foreign bodies stored in the patient's body for a long time, causing shedding, large volume, Disadvantages of electromagnetic adverse effects, not suitable for frequent use
Our previous electric knotter for medical surgery has a complicated structure, and it cannot press the switch button to close the switch and finally tighten the thread. The thread tightening is inaccurate and inconvenient to use.
The ligation problem of minimally invasive surgery has attracted the attention of experts at home and abroad, but it has not been solved so far

Embodiment Construction
[0016] Referring to the accompanying drawings, the motor 1 is glued on the casing 2, the motor shaft is covered with a water-blocking rubber ring 3 and then passed through the motor shaft hole 4 on the casing, and the wire coil 5 is glued on the motor shaft, facing the transmission line at the wire coil 5 There is a wire transmission hole 7 on the plate 6, a normally closed switch 8 is glued to one end of the wire transmission board, and a pressure plate shaft 10 is fixed at one end of the pressure plate 9 to the shaft hole 11 of the pressure plate of the shell (partial sectional view A in the accompanying drawing) The top can be rotated, the closing switch 12 is stuck on the pressing plate, the spring 13 pushes the pressing plate outward on the fixing groove 14, the inner side of the button 15 faces the closing switch 12, and the outer side of the button extends out of the shell through the button hole 16 on the shell. Shell protruding part 17 is inserted with transmission rod...

The deep electric knotter as one medical equipment consists of switch circuit, string feeding and twisting controller, operating device and casing. The switch circuit includes motor, rechargeable battery, normal closing switch and closing switch; the string feeding and twisting controller includes string reel, string feeding board and string feeding rod; the operating device includes button, spring and string pressing board; and the casing includes casing and string cover. The deep electric knotter is used for small cut surgical operation to complete difficult operation ligation.
Description
technical field [0001] The invention is a deep electric knotter, which belongs to medical equipment, and is especially suitable for ligation of deep surgery where hands cannot enter. Background technique [0002] The current operation is generally knotted by hand. For the operation of obesity, deep incision and difficult to expose, it is very difficult to perform tissue ligation, which affects the accuracy and speed of ligation, especially in laparoscopic surgery. Sometimes it is done by enlarging the incision or using silver or titanium clips, but enlarging the incision increases the damage and aggravates the pain of the patient; using silver or titanium clips not only has high cost, but also makes the metal foreign bodies stored in the patient's body for a long time, causing shedding, large volume, The disadvantage of electromagnetic adverse effects is that it should not be used frequently. Our previous electric knotter for medical surgery has a complicated structure, and...
