Description

Technical Field

[0001] The invention relates to the technical field related to surgical traction devices, and in particular to a rapid traction device used for thyroid surgery. Background Art

[0002] Thyroid surgery is a surgical treatment for thyroid diseases, such as thyroid nodules, thyroid tumors, hyperthyroidism or hypothyroidism. Its basic principle is to safely remove the thyroid tissue that causes disease symptoms, relieve symptoms, reduce recurrence, and maximize the prognosis. Traditional thyroidectomy has the disadvantages of leaving scars on the neck and poor cosmetic effects. Laparoscopic thyroid surgery uses laparoscopic techniques to make the tissue structure appear clearer, thereby effectively avoiding damage to nerves, blood vessels and surrounding tissues, reducing surgical complications, and shortening the time it takes to resume neck activity after surgery. At the same time, because the incision is smaller and the location is hidden, it has a good cosmetic effect. In order to adapt to laparoscopic thyroid surgery, external traction equipment such as retractors or suction cups are needed to puncture, adsorb and mechanically pull the skin on the patient's neck or neck, so as to lift the skin on the neck to make room for laparoscopic thyroid surgery. However, in the existing technologies and existing patent technologies, the traction and lifting of the skin on the neck are mostly carried out by coordinating mechanical components with suction cups or retractors. The overall adjustment is not fast enough, not flexible enough, and has certain limitations. It may not be able to be flexibly adjusted according to the patient's condition and the operation of the laparoscope. Summary of the invention

A control terminal 12 is fixedly provided on the base 11, and the control terminal 12 is used to control all motors, electric sliders, electric push rods, sensors, and electromagnets.

[0025] Method of use of the present invention:

[0026] In the initial state:

[0027] The electric push rod 19 is in a fully extended state, the standby electromagnet 41 has not entered the arc plate 15, the lifting block 37 is in contact with the connecting block 36, and the lifting platform 42 is in contact with the first electric slide block 26.

[0028] When the user needs to use the traction device, the user needs to let the patient lie down on the operating table and place the device on both sides of the operating table so that the arc plate 15 is aligned with the patient's neck, and hold the traction net 63 in hand, lower the side of the traction net 63 provided with the circular pad 24 toward the patient's neck, and wrap the exposed skin of the patient's neck, and then the user manually turns on the air pump 13 through the control terminal 12. After the air pump 13 is started, it will pump air into the traction net 63 through the air supply pipe 14, thereby pumping air into the connecting air pipe 21, the connecting circular plate 22, and the circular pad 24. While pumping air, the user needs to manually press the traction net 63 against the patient's neck skin to ensure that each of the circular pads 24 in the traction net 63 and the connecting air pipe 21 away from the magnet 23 are closely attached to the patient's neck skin, so that under the action of the air pump 13, the second adsorption air hole 33 and the first adsorption air hole 34 are kept closely adsorbed to the patient's neck skin.Then the user can operate the surgical equipment to perform surgery. When the patient's neck skin needs to be pulled and lifted, the user needs to drive the electromagnet 38 to energize through the control terminal 12, and start the lifting control component 62 on the No. 1 electric slider 26 through the control terminal 12. After the lifting control component 62 is started, the motor shaft of the motor 30 will drive the pulley 27 to rotate, thereby driving the nut 29 to rotate through the transmission belt 28, thereby driving the lifting platform 42 to rise and fall through the spiral transmission of the nut 29 and the screw 31, thereby driving the lifting platform 42 to lift the electromagnet 38, thereby adjusting the magnet 23 on the traction net 63 to be attracted by the electromagnet 38. The height of the patient's neck skin is pulled to adjust according to actual needs. After adjusting to a suitable height, the distance sensor 40 can be started, and the distance sensor 40 will record the height from the traction net 63 at this time. Then the user can use the control terminal 12 to drive the electric sliders on both sides of the sliding plate 18 and the first electric slider 26 to move. When the sliding plate 18 starts to move, since the neck is a three-dimensional solid, the distance between the distance sensor 40, the electromagnet 38 and the neck will start to change with the movement of the sliding plate 18. When the distance sensor 40 detects that the distance has changed, it will transmit a signal to the control terminal 12. The control terminal 12 receives the signal. After the distance sensor 40 transmits a signal, the corresponding lifting control component 62 will be automatically started to adjust the position of the lifting platform 42 and the electromagnet 38, so as to keep the distance between the electromagnet 38 and the magnet 23 stable, so as to maintain a certain suction force during movement, keep the skin pulled at a consistent height, and facilitate subsequent adjustment to a suitable position, so as to flexibly adjust the traction of the skin on the patient's neck, and reserve sufficient space more quickly and flexibly. When multi-point adjustment is required, the corresponding lifting control component 62 can be driven to start by the control terminal 12. The lifting control component 62 controls the electric push rod 19, according to the data previously recorded by the distance sensor 40 under the lifting platform 42. The height of the connecting plate 20 and the lifting block 37 is controlled to maintain the stability of the suction force, and the control terminal 12 controls the extension and retraction of the electric push rod 19 to control the position of the spare electromagnet 41, thereby realizing multi-point control, so as to complete the traction of the patient's neck skin more quickly and flexibly. After use, the control terminal 12 disconnects the spare electromagnet 41 and the electromagnet 38 to complete the reset of the magnet 23, and the air pump 13 cancels the adsorption of the traction net 63 on the patient's neck skin to remove the traction net 63, and the control terminal 12 drives the electric push rod 19 and the motor 30 to complete the reset of the electric push rod 19 and the lifting control component 62.
