Description

Technical Field

[0001] The invention relates to a traction device, in particular to a multifunctional traction device for minimally invasive treatment. Background Art

[0002] Minimally invasive treatment of gastrointestinal tumors is a surgical method for removing benign intestinal tumors. It is divided into two types: minimally invasive colonoscopy and minimally invasive laparoscopy according to the size, location, and relationship of the benign tumor to the intestine. Because both minimally invasive colonoscopy and minimally invasive laparoscopy require tumor removal, medical staff need to use a traction device to extract the removed tumor.

[0003] At present, there are still some defects and shortcomings in the use of minimally invasive treatment traction devices. The specific areas that need to be improved are as follows:

[0004] 1. Existing traction devices for minimally invasive treatment do not have the function of cleaning and disinfecting the traction wires. After the operation is completed, medical staff usually need to release all the traction wires and remove them for disinfection, and then rewind the wires on the reel after disinfection. The above disinfection method is relatively cumbersome and increases the workload of medical staff.

[0005] 2. The existing minimally invasive treatment traction device cannot quickly replace the traction wire when in use. When the traction wire needs to be replaced, the user needs to first control the reel wheel to rotate forward to release all the reeled traction wires, and then control the reel wheel to reverse to reel in the new reel wire. The above replacement method is inefficient;

[0006] 3. The existing minimally invasive treatment traction device is not convenient for the user to effectively fix the traction device itself when in use, so that the traction of the lesion is easily affected by the instability of the traction device itself during the operation;

[0007] 4. The existing minimally invasive treatment traction device is not convenient for the user to adjust the height and position of the winding wheel according to actual needs, which leads to great limitations in the use of the existing device;

[0008] 5. The existing traction device for minimally invasive treatment cannot guide the winding position of the traction wire when winding it, so that the traction wire is easily wound to the same part of the winding wheel during the winding process, and then the traction wire is easily tangled when it is released later.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention is connected to the mounting plate by arranging a disinfection mechanism. When the winding wheel is used to wind up the traction wire after the operation is completed, the user pulls the traction wire to move the traction wire between the two nozzles and the two curved plates. Then the user controls the electric push rod to retract through the controller to drive the connecting plate to move forward. When the rear curved plate and the nozzle are in contact with the front curved plate and the nozzle, the electric push rod is stopped from retracting. At this time, the user can control the water pump to work through the controller. When the water pump is working, the disinfectant in the liquid storage tank is sucked out and input into the nozzle through the three-way pipe and the telescopic hose, and the disinfectant is sprayed on the traction wire through the nozzle on the nozzle to disinfect the traction wire. The wire guide is rinsed and disinfected, and the disinfectant after rinsing falls into the collection tray for storage and collection. Then the user turns the front winding wheel counterclockwise to pull the left end of the traction wire to the right to reel in the traction wire. At this time, the released traction wire gradually passes through the nozzle and the cleaning sponge, so that the traction wire after use is rinsed with the nozzle and the traction wire is wiped and cleaned with the cleaning sponge, thereby completing the cleaning and disinfection of the traction wire while reeling it in. Medical staff do not need to disassemble the traction wire for cleaning and disinfection, which reduces the workload of medical staff and improves the disinfection efficiency of the traction wire.

[0023] 2. The present invention connects the front and rear winding wheels by setting an inner gear ring, gear six, connecting shaft three, pulley five and pulley six. When the traction wire needs to be disassembled and replaced as a whole, the user can wind the new traction wire around the rear winding wheel for at least one circle, and then the user rotates the front winding wheel clockwise to release the traction wire on the front winding wheel. When the front winding wheel rotates clockwise, the rear winding wheel is driven by the inner gear ring, gear six, connecting shaft three, pulley five and pulley six to rotate counterclockwise to reel in the rear traction wire, thereby reeling in the new traction wire. The threaded rod is then retracted and the threaded rod is retracted to the rear wheel, whereby the user can adjust the threaded rod to the position of the threaded rod to ensure that the threaded rod can be used normally, thereby further improving the functionality of the device.

[0024] 3. The present invention is connected with the fixing frame by setting a fixing mechanism. When installing the device, the user can take the device as a whole and move the fixing frame three to contact the edge of the operating bed, and make the upper inner side of the fixing frame three fit with the upper surface of the operating bed. At this time, the user can rotate the two screws two to move the two screws two upward along the threaded holes. When the two screws two move upward, they push the splint to move upward. When the splint is in close contact with the bottom surface of the operating bed, the rotation of the screws two is stopped, so that the splint and the fixing frame three are used to clamp and fix the device as a whole to the edge of the operating bed, thereby fixing the device as a whole, thereby improving the overall stability of the device and preventing the device from being offset during use and affecting the traction effect.

[0025] 4. The present invention connects the fixed frame with the fixed frame three by setting a motor, gear two and a toothed plate, and sets an adjustment mechanism to connect the fixed frame with the mounting plate. After the device is fixed as a whole on the edge of the operating bed by using the fixing mechanism, the user can control the motor to rotate by the controller to drive gear two. When gear two rotates, it rolls in contact with the toothed plate to drive the fixed frame and the mounting plate to move forward and backward, thereby adjusting the front and rear positions of the mounting plate and the winding mechanism. The user can rotate the worm backward to use the worm gear to drive the rotating shaft one and the rotating plate one to rotate counterclockwise. When the rotating plate one rotates counterclockwise, the gear four rolls in contact with the gear three counterclockwise. At this time, the gear four drives the rotating shaft two and the rotating plate two to rotate clockwise through the connecting shaft one, gear five, the connecting shaft two, the pulley two and the pulley three, thereby using the counterclockwise rotation of the rotating plate one and the clockwise rotation of the rotating plate two to push the mounting plate to move vertically upward, thereby adjusting the height of the mounting plate and the winding mechanism, thereby facilitating the user to adjust the front and rear position and height of the winding mechanism accordingly when using the device, further improving the functionality and applicability of the device.

[0026] 5. The present invention connects the winding wheel and the gear shaft by setting a pulley one and a pulley four. When the user rotates the winding wheel counterclockwise to wind the traction wire, the pulley four and the pulley one drive the gear shaft to rotate. When the gear shaft rotates, the reciprocating screw is driven to rotate through the gear one. When the reciprocating screw rotates, the reciprocating screw nut drives the fixed plate three, the guide plate and the connecting plate to move back and forth, so that the traction wire that reciprocates back and forth of the guide plate and the connecting plate is used to guide the traction wire to be evenly wound on the winding wheel, thereby avoiding uneven winding of the traction wire on the winding wheel and affecting the subsequent normal use.

[0048] The operating steps of the present invention are:

[0049] When using the device, the user can take the device and move it as a whole to make the fixing frame 31 contact with the edge of the operating bed, and make the upper inner side of the fixing frame 31 fit with the upper surface of the operating bed. At this time, the user can rotate the two screw rods 2 35 to make the two screw rods 2 35 move upward along the threaded hole 34. When the two screw rods 2 35 move upward, they push the clamping plate 33 to move upward. When the clamping plate 33 is in close contact with the bottom surface of the operating bed, the rotation of the screw rods 2 35 is stopped. Then the user can adjust the front and rear position and height of the mounting plate 1 and the winding mechanism 8 according to the position of the patient's lesion. The user can control the motor 39 through the controller 9 to drive the gear 2 38 to rotate, and the gear 2 38 fits the gear plate when it rotates. The fixing frame 5 and the mounting plate 1 are moved forward and backward by rolling 32, and the front and rear positions of the mounting plate 1 and the winding mechanism 8 are adjusted. The user can rotate the worm 68 backward to use the worm gear 67 to drive the rotating shaft 1 62 and the rotating plate 1 63 to rotate counterclockwise. When the rotating plate 1 63 rotates counterclockwise, the gear 4 610 fits the gear 3 65 and rolls counterclockwise. At this time, the gear 4 610 drives the rotating shaft 2 616 and the rotating plate 2 614 to rotate clockwise through the connecting shaft 1 69, the gear 5 611, the connecting shaft 2 612, the pulley 2 613 and the pulley 3 615, so that the mounting plate 1 is pushed to move vertically upward by the counterclockwise rotation of the rotating plate 1 63 and the clockwise rotation of the rotating plate 2 614.

Then the user can move the pulling wire 84 to the top of the connecting plate 27 and rotate the front winding wheel 82 counterclockwise to release the pulling wire 84. Then the medical staff connects the pulling wire 84 to the lesion and rotates the front winding wheel 82 clockwise to tighten the pulling wire 84, so as to use the pulling wire 84 to pull the lesion. When the winding wheel 82 is used to wind up the traction wire 84, the user pulls the traction wire 84 to move the traction wire 84 between the two nozzles 223 and the two curved plates 222, and then the user controls the electric push rod 221 to contract through the controller 9 to drive the connecting plate 27 to move forward. When the rear curved plate 222 and the nozzle 223 contact the front curved plate 222 and the nozzle 223, the electric push rod 221 stops contracting. At this time, the user can control the water pump 24 to work through the controller 9. When the water pump 24 works, the disinfectant in the liquid storage tank 21 is sucked out through the three-way pipe 23 and the telescopic hose 25 and input into the nozzle. 223, and the disinfectant is sprayed on the traction thread 84 through the nozzle on the nozzle 223 to rinse and disinfect the traction thread 84, and the disinfectant after rinsing falls into the collection tray 26 for storage and collection, and then the user rotates the front winding wheel 82 counterclockwise to pull the left end of the traction thread 84 to move to the right to reel the traction thread 84, at this time, the released traction thread 84 gradually passes through the nozzle 223 and the cleaning sponge, so that the traction thread 84 after use is rinsed with the nozzle 223 and the traction thread 84 is wiped and cleaned with the cleaning sponge. After the reeling is completed, the user opens the valve to allow the collection tray 26 to collect the traction thread 84. The dirty liquid in the disk 26 is discharged through the discharge pipe 224. When the user rotates the winding wheel 82 counterclockwise to wind up the traction wire 84, the gear shaft 212 is driven to rotate through the pulley four 85 and the pulley one 217. When the gear shaft 212 rotates, the reciprocating screw 216 is driven to rotate through the gear one 218. When the reciprocating screw 216 rotates, the fixed plate three 214, the guide plate 27 and the connecting plate 28 are driven to reciprocate back and forth through the reciprocating screw nut 215, so that the traction wire 84 that reciprocates back and forth by the guide plate 27 and the connecting plate 28 is guided to be evenly wound on the winding wheel 82.

[0051] When it is necessary to disassemble and replace the traction wire 84 as a whole, the user can wind the new traction wire 84 around the rear winding wheel 82 for at least one week, and then the user rotates the front winding wheel 82 clockwise to release the traction wire 84 on the front winding wheel 82. When the front winding wheel 82 rotates clockwise, the inner gear ring 86, gear six 89, connecting shaft three 87, pulley five 88 and pulley six drive the rear winding wheel 82 to rotate counterclockwise to reel in the rear traction wire 84 to complete the quick replacement. After using the rear winding wheel 82 to reel in the traction wire 84, the user can rotate the screw rod 1 213 clockwise to make the nut 220 drive the fixing frame 2 219, the guide plate 27 and the connecting plate 28 to move backward, thereby moving the nozzle 223 and the arc plate 224 to correspond to the rear winding wheel 82.
