Description

[0002] As people's living standards improve, their eating habits are also changing greatly. Uncontrolled intake of high fat and high sugar, reduced exercise, long periods of sitting and staying up late have caused the liver and the diseased parts of the liver or kidney to be in an overloaded working state for a long time. Without proper conditioning, it is very easy to develop lesions and eventually lead to the formation of liver cancer and kidney cancer. Laser radiofrequency ablation uses laser energy to heat and destroy the diseased tissue. This method has the advantages of less trauma, faster recovery, and usually no need for long-term hospitalization. Existing laser radiofrequency ablation surgeries are mostly performed on patients through a single surgical channel. However, since the shape of the lesions of the liver or kidney is usually irregular, during laser radiofrequency ablation surgery, the surgical instruments need to swing a large amplitude in order to comprehensively treat the lesions. During the swinging of the equipment, it is very likely to further squeeze the abdominal wall of the human body, causing the surgical channel of the abdominal wall to expand and cause harm to the human body.

[0037] This embodiment discloses a laser radiofrequency ablation device, such as Figures 1 to 8 As shown, including:

[0038] A combination, wherein the combination comprises at least two guide assemblies 10, wherein the guide assembly 10 comprises a first guide unit 11, a second guide unit 12, a third guide unit 13, a guide groove 14, and a guide protrusion 16; the first guide unit 11, the second guide unit 12, and the third guide unit 13 are fixedly connected in sequence; the hollow cavity of the first guide unit 11, the hollow cavity of the second guide unit 12, and the hollow cavity of the third guide unit 13 are interconnected; the guide protrusion 16 is fixedly connected to the outer surface of the first guide unit 11, the guide groove 14 is opened on the inner surface of the third guide unit 13, and the width of the guide groove 14 gradually decreases from the middle position of the guide groove 14 in the length direction toward the two ends of the guide groove 14; two adjacent guide assemblies 10 are movably connected in sequence, and the outer surface of the first guide unit 11 on one guide assembly 10 abuts against the inner surface of the third guide unit 13 on the other guide assembly 10; the guide protrusion 16 on one guide assembly 10 abuts against the guide groove 14 on the adjacent other guide assembly 10;

[0039] A steering assembly 40, one end of which is fixedly connected to one end of the assembly, and a hollow cavity on the steering assembly 40 is connected to a hollow cavity of the guide assembly 10 in the assembly;

[0040] The sleeve 50, the combination and the steering assembly 40 can enter and exit the hollow cavity of the sleeve 50 along the axis of the sleeve 50;

[0041] The driving assembly is detachably connected to the third guide unit 13 at one end of the combination away from the steering assembly 40, and the driving assembly is transmission-connected to the guide assembly 10 and can drive the guide assembly 10 to swing. The driving assembly is transmission-connected to the steering assembly 40.

[0042] In this embodiment, the driving component drives the guide component 10 to swing and drives the steering component 40 to move or rotate, thereby changing the direction of the guide component 10, so that during the laser ablation operation, the position of the guide component 10 can be adjusted to accurately locate the tumor in the diseased part of the liver or kidney, so as to facilitate the removal of tumors in different parts of the diseased part of the liver or kidney after laser ablation during the operation. The width of the guide groove 14 gradually decreases from the middle position of the guide groove 14 toward the two ends of the guide groove 14 in the length direction; the two adjacent guide components 10 are movably connected in sequence, the outer surface of the first guide unit 11 on one guide component 10 abuts against the inner surface of the third guide unit 13 on the other guide component 10, and the guide protrusion 16 on one guide component 10 abuts against the guide groove 14 on the other adjacent guide component 10; so that the friction coefficient of the guide protrusion 16 is different when it rotates at different angles in the guide groove 14. When the guide component 10 swings within a certain angle range, the friction between the guide protrusion 16 and the guide groove 14 is small, and it can swing quickly. When it swings within another angle range, the friction between the guide protrusion 16 and the guide groove 14 is large, so that when the friction is large, it is convenient to accurately adjust the positioning. The two adjacent guide components 10 can be set to have a smaller friction force when the steering angle is between -15° and 15°. At this time, the guide protrusion 16 can swing quickly in the guide groove 1414. The two adjacent guide components 10 have a larger friction force when the steering angle is between -30° and -15° or 15° and 30°. The friction force is maximum when it is less than -30° and greater than 30°. In this way, when the friction force is large, it is convenient to accurately adjust the positioning; and it is easy to find the location of the tumor for laser ablation surgery.

[0043] In addition, in this embodiment, corresponding materials can be selected for the guide protrusions 16 at different positions in the guide assembly 10, and different friction forces between the guide protrusions 16 and the guide grooves 14 can be achieved according to the different materials of the guide protrusions 16. In the above, when the laser radio frequency ablation device is not working, the guide assembly 10 and the steering assembly 40 can be accommodated in the hollow cavity of the sleeve 50, so as to protect the guide assembly 10 and the steering assembly 40, so as to reduce the possibility of the guide assembly 10 and the steering assembly 40 being contaminated by dust.

[0044] In some embodiments, Figure 3 , Figure 4 , Figure 5 As shown, there are two guide grooves 14 , the central cross section of the third guide unit 13 is symmetrically arranged, and there are two guide protrusions 16 , and the two guide protrusions 16 abut against the two guide grooves 14 .

[0045] In this embodiment, by providing two guide grooves 14 and two guide protrusions 16, after the two guide grooves 14 and the two guide protrusions 16 abut against each other, the stability of the abutment between two adjacent guide assemblies 10 can be further enhanced, and the swing of the guide assemblies 10 can also be easily controlled.

[0046] In some embodiments, the minimum gap between the guide groove 14 and the guide protrusion 16 after they abut against each other is a first set value, and the maximum gap is a second set value.

[0047] In this embodiment, the first setting value is 0.01 mm, and the second setting value is 0.05 mm. By setting the first setting value to 0.01 mm and the second setting value to 0.05 mm, the package guide groove 14 and the guide protrusion 16 can move relative to each other under the action of external force, and the slipping or locking phenomenon caused by the gap between the guide protrusion 16 and the guide groove 14 being too large or too small can be avoided.

[0048] In some embodiments, Figure 1 , Figure 6 , Figure 7 , Figure 8 As shown, the combination includes three guide assemblies 10 , and the outer surfaces of the first guide units 11 of two adjacent guide assemblies 10 abut against the inner surface of the third guide unit 13 .

[0049] In this embodiment, the number of the assembly is set to three guide assemblies 10, which can ensure that the guide assembly 10 can swing at a larger angle and facilitate the control of the swing of the guide assembly 10. However, in a specific working environment, the number of guide assemblies 10 can be set according to actual needs and is not limited to the above three guide assemblies 10.

[0050] In some embodiments, Figure 1As shown, the driving assembly includes a connecting rope 30 and a controller (not shown in the figure), two first perforations 15 are arranged on the third guide unit 13 on each of the guide assemblies 10, and there are two connecting ropes 30, one end of the two connecting ropes 30 are detachably connected to the two first perforations 15 on the third guide unit 13 on the end of the combination away from the steering assembly 40, and the connection points between the two connecting ropes 30 and the two first perforations 15 are located on the central cross-section of the guide assembly 10, and the central cross-section longitudinally cuts through the middle of the guide groove 14; the other ends of the two connecting ropes 30 pass through the remaining first perforations 15 in turn, and are transmission-connected to the controller through the hollow cavity of the sleeve 50; the controller is transmission-connected to the steering assembly 40, and is used to drive the guide assembly 10 to rotate, and the controller controls the swing of the two adjacent guide assemblies 10 by stretching one connecting rope 30 and releasing the other connecting rope 30.

[0051] In this embodiment, if Figure 1 As shown, the controller is provided with a first rotating module for driving the connecting rope 30 to generate tension, and the first rotating module can be a motor, or other power modules can be selected as needed. When the first rotating module is a motor, by fixing one end of the connecting rope 30 on the rotating shafts of the two motors, the controller controls the forward and reverse rotation of the two motors, so as to realize that the connecting rope 30 pulls the guide assembly 10 to swing. The connection points of the two connecting ropes 30 and the two first perforations 15 are located on the central cross section of the guide assembly 10, so that when the swing angle of the guide assembly 10 is constant, the controller controls the motor to apply the minimum tension, thereby saving the electric energy for driving the motor shaft to rotate. In this embodiment, the controller also includes a telescopic module, which can be an electric telescopic rod, and the output shaft of the electric telescopic rod is detachably connected to one end away from the steering assembly 40 of the assembly, and the controller also includes a second rotating module, which can be a motor, and the output end of the motor is detachably connected to the fixed end of the telescopic module. The telescopic module can be driven to rotate by the second rotating module, and the steering assembly can be rotated, thereby realizing the rotation of the driving assembly, which is convenient for finding the lesion site of the liver or kidney.

[0052] In some embodiments, Figure 1As shown, the steering assembly includes a steering tube 41 and a plurality of second through holes 42, wherein the plurality of second through holes 42 are formed on the steering tube 41, and the other ends of the two connecting ropes 30 pass through the second through holes 42 in a straight line. One end of the steering tube 41 is fixedly connected to the first steering unit or the third steering unit at the other end of the combination away from the guide tube 20, and the hollow cavity of the steering tube 41 is connected to the hollow cavity of the first rotating unit or to the hollow cavity of the third steering unit. The other end of the steering tube 41 is transmission-connected to the controller, and the controller can drive the steering tube 41 to rotate.

[0053] In this embodiment, if Figure 1 As shown, by setting a plurality of second perforations 42 on the steering tube 41, the other ends of the two connecting ropes 30 pass through the second perforations 42 in a straight line, which can prevent the connecting ropes 30 from being partially loosened during the process of the connecting ropes 30 pulling the guide assembly 10 to swing. The steering tube 41 in the steering assembly 40 is detachably connected to the output shaft of the telescopic module relative to one end fixedly connected to the first steering unit 11 or the third steering unit. The controller controls the output end of the second rotating module to rotate by controlling the output end telescopic machine of the telescopic module, thereby realizing the steering tube 41 driving the guide assembly 10 to move and rotate. It should be noted that in the above embodiment, the position of the steering tube 41 is preferably always located in the sleeve 50, and does not move out of the sleeve 50 with the guide assembly 10. The purpose of doing so is to minimize the excessive contact between the components of the laser radiofrequency ablation device and the lesion site of the liver or kidney, reduce excessive friction with the lesion site of the liver or kidney, and avoid the lesion site of the liver or kidney from being damaged by the steering tube 41.

[0054] In some embodiments, Figure 4 , Figure 5 As shown, the second through hole 42 is opened on the steering tube 41 with the central cross section of the steering tube 41 as a symmetry plane.

[0055] In this embodiment, the number of the second perforations 42 can be set as needed to facilitate the stretching and releasing of the connecting rope 30, thereby avoiding partial slack of the connecting rope 30 during the process of the controller controlling the motor to stretch and release the connecting rope 30, thereby causing the swing angle of the guide component 10 to be too large or too small, and the steering of the guide component 10 cannot be accurately controlled.

[0056] In some embodiments, Figure 1 , Figure 2 , Fig. 9As shown, the laser radio frequency ablation device also includes a guide tube 20, one end of which is fixedly connected to the third guide unit 13 or the first guide unit 11 away from the steering assembly 40, the hollow cavity of the guide tube 20 is connected to the hollow cavity of the third guide unit 13 or the first guide unit 11, and the guide tube 20 can move in and out of the hollow cavity of the sleeve 50 along the axis of the sleeve 50.

[0057] In this embodiment, if Fig. 9 As shown, by providing the guide tube 20, the possible contact between the laser radiofrequency ablation device and the internal organs of the human body can be smoother. Compared with the first guide unit 11, the second guide unit 12, and the third guide unit 13 in the guide assembly 10, the guide tube 20 is in a uniform circular tube shape, while the surfaces of the first guide unit 11, the second guide unit 12, and the third guide unit 13 are in an arc shape. When the guide tube 20 may contact the internal organs of the human body, the possible contact between the guide tube 20 and the internal organs of the human body is smoother. During the rotation of the guide tube 20, the squeezing of the internal organs of the human body can be reduced, and the internal organs of the human body can be prevented from being damaged during the operation. The guide assembly 10 is driven by the connecting rope 30 to adjust the direction of the guide tube 20, and the guide tube 20 is driven to rotate by controlling the steering assembly 40 to change the swing and steering of the guide tube 20, so that the position of the guide tube 20 can be adjusted during the laser ablation operation, and the tumor in the lesion part of the liver or kidney can be accurately located, so as to facilitate the removal of the tumor after laser ablation during the operation.

[0058] In some embodiments, the guide tube 20 is provided with removal forceps 60, a laparoscope 70, and a laser head 80, and the laparoscope 70 and the laser head 80 are electrically connected to the controller.

[0059] In this embodiment, when the guide tube 20 is not provided, the removal forceps 60, laparoscope 70, and laser head 80 are provided in the hollow cavity of the guide assembly 10. By providing the guide tube 20, since the guide tube 20 is in the shape of a round tube, the removal forceps 60, laparoscope 70, and laser head 80 can be relatively stably provided in the guide tube 20, and it is more convenient to remove the tumor after laser ablation. Because the shape of the hollow cavity of the guide assembly 10 is irregular, the cavity at the first guide unit 11 and the third guide unit 13 is larger, and the cavity at the second guide unit 12 is smaller, so when removing the tumor, it is easy for the tumor to pass through the first guide unit 11 or the third guide unit 13 but not the second guide unit 12, which complicates the operation and is inconvenient to remove the tumor.

[0060] This embodiment discloses a laser radiofrequency ablation device control method, comprising the following steps:

[0061] S11: inserting the combination and the steering assembly 40 into the hollow cavity of the sleeve along the axis of the sleeve;

[0062] S12: Passing the end of the cannula containing the assembly into the lesion site of the liver or kidney through the tumor removal channel of the human body;

[0063] S13: pushing the steering assembly through the driving assembly to move the assembly out of the hollow cavity of the sleeve;

[0064] S14: The driving component is used to swing the assembly so that the guide component 10 is swung, and the driving component is used to rotate the steering component 40 to find the lesion site.

[0065] In this embodiment, step S4 is specifically operated as follows: stretching one of the connecting ropes 30 through the controller, releasing the other connecting rope 30, controlling the two adjacent guide assemblies 10 to swing, and the controller controls the steering tube 41 to rotate, so that the guide tube 20 swings up and down and left and right to find the location of the tumor. When the laparoscope 70 finds the tumor, the laser head 80 abslates the tumor, and the ablated tumor is removed by the removal forceps 60.

[0066] In this embodiment, the laparoscope 70 and the laser head 80 are electrically connected to the controller, and the tumor information in the diseased part of the liver or kidney is uploaded to the controller for display through the laparoscope 70, and the tumor residues after ablation are removed by controlling the removal forceps 60 (the removal forceps 60 can be manually controlled).

[0067] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present disclosure.
