Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an ablation probe structure and an ablation electrode dissecter. Background Technology

[0002] Currently, surgical procedures utilize tools such as electrocautery hooks and electrocautery rods. These tools can only be used for electrocautery and electrocoagulation individually, and cannot be switched between operations. During surgery, bleeding often requires first suctioning the blood with a suction device, then removing the suction device before inserting the electrocautery knife for cutting. When hemostasis is needed, the electrocoagulation instrument must be switched. Pure electrocautery cutting generates smoke, which accumulates in the abdominal cavity and obscures the laparoscopic surgical field. Existing technologies, such as the Chinese patent application CN202322323295.3, while avoiding the need for specialized instruments to switch between cutting and electrocoagulation, still require retracting the scalpel handle when switching from cutting to electrocoagulation. Repeated retraction during surgery wastes and delays the procedure and poses a risk of damaging healthy tissue. To further improve the safety and efficiency of the switching process... Utility Model Content

[0003] This invention addresses the technical problem of how to improve the switching efficiency and safety between cutting and electrocoagulation in ablation surgery by providing an ablation probe structure and an ablation electrode dissector.

[0004] In view of the above technical problems, this utility model provides an ablation probe structure, including an inner tube, an ablation probe body mounted on the inner tube, a mounting portion mounted on the inner tube at one end away from the ablation probe body, an outer tube interference-fitted onto the inner tube, a connecting portion sleeved on the outer tube, and an elastic component disposed between the mounting portion and the connecting portion. The mounting portion is provided with a conductive component electrically connected to the inner tube. The ablation probe body includes a control portion connected to the inner tube and an electrocoagulation cutting blade connected to the control portion. When the inner tube extends or retracts along the length direction of the outer tube to the outside of the outer tube under the push of the elastic component, the first arc-shaped surface of the electrocoagulation cutting blade constitutes a cutting surface, and the second arc-shaped surface of the electrocoagulation cutting blade constitutes an electrocoagulation plane.

[0005] Preferably, the second arc-shaped surface is bent at a preset angle to the first arc-shaped surface, the central angle of the electrocoagulation cutting blade is 0.6°-0.8°, and the preset angle is 13°-33°.

[0006] Preferably, the width of the electrocoagulation cutting blade is 2.5mm-5mm, the length of the electrocoagulation cutting blade is 2mm-6mm, and the thickness of the electrocoagulation cutting blade is 0.2mm-1.5mm.

[0007] Preferably, the projected length of the control unit and the electrocoagulation cutting blade in the horizontal plane is 24mm-30mm.

[0008] Preferably, the inner tube is provided with a mounting groove for mounting the control unit, and both the inner tube and the outer tube are provided with insulating sleeves.

[0009] Preferably, the elastic component includes a fixing bracket sleeved on the outer tube for connecting the connecting part, a spring sleeved on the fixing bracket, an elastic hook disposed on the mounting part, and two positioning holes spaced apart on the connecting part for engaging with the elastic hook.

[0010] Preferably, the elastic component further includes a switching button, the switching button including a buckle mounted on the connecting part and a key shell connected to the buckle, the key shell being provided with an actuating block that mates with the positioning hole.

[0011] Preferably, the conductive components are a conductive spring and a power plug disposed on the mounting portion, and the inner tube is connected to the power plug through the conductive spring.

[0012] Preferably, the end of the mounting part away from the ablation probe body is provided with an air tube that connects to the outer tube, and an air valve is installed on the air tube.

[0013] This invention also provides an ablation electrode dissecter, including the above-mentioned ablation probe structure.

[0014] In this invention, the ablation probe structure includes an inner tube, an ablation probe body mounted on the inner tube, a mounting portion mounted on the inner tube at one end away from the ablation probe body, an outer tube interference-fitted onto the inner tube, a connecting portion sleeved on the outer tube, and an elastic component disposed between the mounting portion and the connecting portion. The mounting portion is provided with a conductive component electrically connected to the inner tube. The ablation probe body includes a control portion connected to the inner tube and an electrocoagulation cutting blade connected to the control portion. When the inner tube extends or retracts along the length direction of the outer tube to the outside of the outer tube under the push of the elastic component, the first arc-shaped surface of the electrocoagulation cutting blade forms a cutting surface, and the second arc-shaped surface of the electrocoagulation cutting blade forms an electrocoagulation plane. The end of the inner tube where the ablation probe body is mounted passes through the inner cylinder of the outer tube. The elastic component connects the mounting portion and the connecting portion to allow the ablation probe body mounted on the inner tube to extend or retract along the length direction of the inner cylinder of the outer tube.

[0015] In this invention, the inner tube, which houses the ablation probe, is interference-fitted into the outer tube and electrically connected to the conductive component. The inner tube is constantly energized during operation. The elastic component connects the mounting and connecting parts, allowing the inner tube to extend and retract along the length of the outer tube under the push of the elastic component. When the elastic component is compressed, it pushes the inner tube to extend beyond the outer tube. At this time, the first arc-shaped surface of the electrocoagulation cutting blade of the energized ablation probe can be used to cut and separate the lesion tissue. The tilt angle of the rotation control unit allows the second arc-shaped surface of the electrocoagulation cutting blade to contact the tissue requiring electrocoagulation, completing the electrocoagulation. In other words, cutting and electrocoagulation can be switched at the same position without the need for auxiliary instruments. When switching from cutting to electrocoagulation, there is no need to change the electrocoagulation instrument or retract the inner tube to the outer tube. As long as the ablation probe extends beyond the outer tube, the switching between cutting and electrocoagulation can be completed simply by rotating the tilt angle of the control unit. Simultaneously, the smoking procedure can be completed, reducing the time required for instrument changes or position adjustments and shortening the surgical time. During electrocoagulation, the second arc-shaped surface of the cutting blade has a larger contact area with the lesion tissue, allowing for the treatment of a larger area of ​​tissue in one operation and expanding the treatment scope of a single surgery.

Detailed Implementation

[0023] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] It should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0025] like Figures 1 to 4 As shown, an embodiment of this utility model provides an ablation probe structure, including an inner tube 1, an ablation probe body 2 mounted on the inner tube 1, a mounting portion 3 mounted on the inner tube 1 at one end away from the ablation probe body 2, an outer tube 4 interference-fitted onto the inner tube 1, a connecting portion 5 sleeved on the outer tube 4, and an elastic component disposed between the mounting portion 3 and the connecting portion 5. The mounting portion 3 is provided with a conductive component electrically connected to the inner tube 1. The ablation probe body 2 includes a control portion 201 connected to the inner tube 1 and an electrocoagulation cutting blade 202 connected to the control portion. When the inner tube 1 is extended or retracted along the length direction of the outer tube 4 to the outside of the outer tube 4 under the push of the elastic component, the first arc-shaped surface 203 of the electrocoagulation cutting blade 202 constitutes a cutting surface, and the second arc-shaped surface 204 of the electrocoagulation cutting blade 202 constitutes an electrocoagulation plane. Understandably, the end of the inner tube 1 on which the ablation probe body 2 is mounted passes through the inner cylinder of the outer tube 4, and the elastic component connects the mounting part 3 and the connecting part 5 so that the ablation probe body 2 mounted on the inner tube 1 can extend and retract along the length direction of the inner cylinder of the outer tube 4.

[0026] In the above embodiments of this utility model, the inner tube 1, on which the ablation probe body 2 is installed, is interference-fitted into the inner cylinder of the outer tube 4, and the inner tube 1 is electrically connected to the conductive component. The inner tube 1 is in a normally energized state during operation. The elastic component connects the mounting part 3 and the connecting part 5, allowing the inner tube 1 to extend and retract along the length of the outer tube 4 under the push of the elastic component. That is, when the elastic component is compressed, it pushes the inner tube 1 to extend along the length of the outer tube 4 to the outside of the outer tube 4. At this time, the first arc-shaped surface 203 of the electrocoagulation cutting blade 202 of the ablation probe body 2, which is in an energized state, can be used to cut and separate the lesion tissue. The tilt angle of the rotation control part 201 can be adjusted according to the operating environment to allow the electrocoagulation cutting blade 202 to complete the cut at a suitable angle. When hemostasis is required, the appropriate angle control part 201 is rotated again to another suitable angle, causing the second arc-shaped surface 204 of the electrocoagulation cutting blade 202 to contact the tissue to be electrocoagulated, thus completing the electrocoagulation. Simultaneously with cutting and electrocoagulation, a smoking procedure can also be performed.

[0027] When the elastic component is released, it pushes the inner tube 1 to retract towards the mounting part 3 into the inner cavity of the outer tube 4. At this time, the electrocoagulation cutting blade 202 is in a non-energized state, and the outer end face of the outer tube 4 forms a plane for absorbing blood. That is, blood can flow from the port of the outer end face of the outer tube 4 into the outer tube 4 to complete the liquid suction operation.

[0028] In this invention, since the inner tube 1, on which the ablation probe body 2 is installed, is interference-fitted into the outer tube 4, and the inner tube 1 is electrically connected to the conductive component, the inner tube 1 is in a normally energized state during operation. The elastic component connects the mounting part 3 and the connecting part 5, allowing the inner tube 1 to extend and retract along the length direction of the outer tube 4 under the push of the elastic component. When the elastic component is compressed, it pushes the inner tube 1 to extend along the length direction of the outer tube 4 to the outside of the outer tube 4. At this time, the first arc-shaped surface 203 of the electrocoagulation cutting blade 202 of the ablation probe body 2, which is in an energized state, can be used to cut and separate the lesion tissue; the control part 201 can also be rotated. The tilt angle allows the second arc-shaped surface 204 of the electrocoagulation cutting blade 202 to contact the tissue requiring electrocoagulation, completing the electrocoagulation process. This means that cutting and electrocoagulation can be switched at the same position without the need for auxiliary instruments. When switching from cutting to electrocoagulation, there is no need to change the electrocoagulation instrument or retract the inner tube 1 to the outer tube 4. As long as the ablation probe body 2 extends outside the outer tube 4, simply rotating the tilt angle of the control unit 201 completes the switch between cutting and electrocoagulation. Simultaneously, the smoking procedure can be completed, reducing the time required for instrument changes or position adjustments and shortening the operation time. Switching functions by rotating the control unit 201 also allows for more precise control of the cutting and electrocoagulation positions during the operation, improving surgical accuracy. Compared to existing technologies, the second arc-shaped surface 204 of the electrocoagulation cutting blade 202 has a larger contact area with the lesion tissue during electrocoagulation, allowing for the treatment of a larger area of ​​tissue in a single operation, expanding the treatment range of a single surgery. The larger contact area also helps reduce tissue damage and promotes postoperative healing.

[0029] In one embodiment, such as Figures 2 to 3 As shown, the second arc-shaped surface 204 bends towards the first arc-shaped surface at a preset angle. The central angle of the electrocoagulation cutting blade 202 is 0.6°-0.8°, and the preset angle is 13°-33°. Understandably, the preset angle is the angle between the tangent of the second arc-shaped surface 204 and the extension of the control unit 201. The preset angle can be set according to the requirements of surgical precision, efficiency, and safety, and can be 13°, 23°, or 33°. With the above-mentioned parameter settings for the second arc-shaped surface 204, the electrocoagulation cutting blade 202 can more precisely contact tissues of different shapes, thereby achieving more refined surgical operations. The second arc-shaped surface 204 helps improve cutting efficiency, especially in surgeries requiring precise resection. The surgeon can adjust the inclination of the second arc-shaped surface 204 in contact with the tissue according to surgical needs to achieve optimal tissue contact and electrocoagulation effect. The central angle can be 0.6, 0.7° or 0.8°, which helps to concentrate the electrocoagulation energy, improve the electrocoagulation effect of local tissues, and thus more effectively achieve hemostasis and tissue coagulation. At the same time, the energy distribution is more concentrated during the electrocoagulation process, reducing damage to surrounding healthy tissues.

[0030] In one embodiment, such as Figures 2 to 3 As shown, the width of the electrocoagulation cutting blade 202 is 2.5mm-5mm, the length of the electrocoagulation cutting blade 202 is 2mm-6mm, and the thickness of the electrocoagulation cutting blade 202 is 0.2mm-1.5mm. Understandably, setting the width, length, and thickness of the electrocoagulation cutting blade 202 to an appropriate ratio can provide optimized cutting results, ensure a smooth and precise switching process between cutting and electrocoagulation, and precise dimensional control helps improve the overall quality of the surgery. Providing precise cutting and electrocoagulation capabilities can reduce surgical time.

[0031] In one embodiment, such as Figures 2 to 3 As shown, the projected length of the control unit 201 and the electrocoagulation cutting blade 202 in the horizontal plane is 24mm-30mm. Understandably, considering the operational range and flexibility in actual surgery, the total length (projected length) of the control unit 201 and the electrocoagulation cutting blade 202 is controlled within the range of 24mm-30mm, preferably 24mm. This provides more operational space for surgical operations such as cutting, electrocoagulation, fumigation, and fluid aspiration, and allows the surgeon to more flexibly adjust the angle and depth of cutting or electrocoagulation during the procedure. The surgeon can better control the surgical tools and reduce the risk of accidental damage to surrounding tissues. Preferably, the ablation probe body 2 is made of conductive material, and the control unit 201 and the electrocoagulation cutting blade 202 can be an integrally formed structure, ensuring effective energy transfer during electrocoagulation, improving electrocoagulation efficiency, and guaranteeing stability during use.

[0032] Control unit 201 Control unit 201 Control unit 201 In one embodiment, as Figure 1 As shown, the inner tube 1 is provided with a mounting groove (not shown) for mounting the control unit 201, and both the inner tube 1 and the outer tube 4 are provided with insulating sleeves. Understandably, the control unit 201 is installed in the mounting groove 101 opened on the inner tube 1, and the installation method can be welding, which can improve the stability of the connection between the ablation probe body 2 and the inner tube 1. The insulating sleeves on both the inner tube 1 and the outer tube 4 isolate the electrical conductivity between the outer tube 4 and the inner tube 1, and also prevent electrical conductivity between the inner tube 1 and the outer tube 4 from posing a danger to the surgical operator.

[0033] In one embodiment, such as Figure 1 and 4As shown, the elastic component includes a fixing frame 6 sleeved on the outer tube 4 for connecting the connecting part 5, a spring 7 sleeved on the fixing frame 6, an elastic hook 8 disposed on the mounting part 3, and two positioning holes 9 spaced apart on the connecting part 5 to engage with the elastic hook 8. Understandably, the fixing frame 6 is fixedly sleeved on the side of the outer tube 4, which is fitted with an insulating sleeve, away from the port of the outer tube 4. The fixing frame 6 is provided with a limiting ring that restricts the movement of one end of the spring 7. The outer contour of the limiting ring is larger than the diameter of the spring 7. The port of the connecting part 5 near the port of the outer tube 4 is smaller than the outer contour of the limiting ring. The diameter of the end of the mounting part 3 near the other end of the spring 7 is equal to the latter being larger than the diameter of the spring 7. Thus, the spring 7 is movably mounted between the inner cylinder of the connecting part 5 and the mounting part 3, and the connecting part 5 is sleeved on the outer wall of the mounting part 3. Insert the inner tube 1 into the outer tube 4, push the mounting part 3 toward the connecting part 5, and the elastic hook 8 engages with the positioning hole 9 to complete the installation of the electrocautery structure; the distance between the two positioning holes 9 determines the stroke of the ablation probe body 2 extending out of the stepped surface 402. Among them, the positioning hole 9 on the connecting part 5 near the port of the outer tube 4 is the cutting position positioning hole 9. When the elastic hook 8 engages with the cutting position positioning hole 9, the stroke of the ablation probe body 2 is the longest, and the lesion can be cut and separated at this time; the other positioning hole 9 is the electrocoagulation position positioning hole 9. When the elastic hook 8 engages with the electrocoagulation position positioning hole 9, the ablation probe body 2 extends outside the outer tube 4, and the hemostasis electrocoagulation operation can be performed at this time.

[0034] In one embodiment, such as Figure 4 As shown, the elastic component also includes a switching button 10, which includes a buckle 1001 mounted on the connecting part 5 and a key shell 1002 connected to the buckle 1001. The key shell 1002 is provided with an actuating block 1003 that mates with the positioning hole 9. That is, when the actuating block 1003 on the key shell 1002 is pressed, the actuating block 1003 presses the elastic hook 8 mounted in the cutting position positioning hole 9. At this time, the pressure released by the spring 7 forces the mounting part 3 away from the connecting part 5, so that the elastic hook 8 is engaged in the electrocoagulation position positioning hole 9; pressing the mounting part 3 pushes the mounting part 3 toward the connecting part 5, at which time the spring 7 is compressed, so that the elastic hook 8 is engaged in the cutting position positioning hole 9. In this way, the surgeon can switch between cutting and electrocoagulation hemostasis with one hand without frequently changing instruments.

[0035] In one embodiment, such as Figures 1 to 2As shown, the conductive components are a conductive spring 11 and a power plug 12 disposed on the mounting part 3. The inner tube 1 is connected to the power plug 12 through the conductive spring 11. Understandably, the end of the inner tube 1 can be connected to the conductive spring 11 via a conductive connecting block. When the power plug 12 is connected to an external power source, both the inner tube 1 and the ablation probe body 2 are in a conductive state. Further, the conductive spring 11 is disposed on the inner tube 1, with one end of the conductive spring 11 away from the ablation probe body 2 disposed on the opposite side of the elastic hook 8, and on the same horizontal line as the end of the elastic hook 8. When the elastic component is released, it pushes the inner tube 1 back towards the mounting part 3, causing the ablation probe body 2 to retract into the inner cavity of the outer tube 4. At this time, the port of the outer tube 4 forms a washing fluid plane, allowing blood from the lesion tissue to flow into the outer tube 4 through the port and be drained.

[0036] In one embodiment, such as Figures 1 to 2 As shown, the end of the mounting part 3 away from the ablation probe body 2 is provided with a trachea 13 that connects to the outer tube 4. An air valve is installed on the trachea 13, and the trachea 13 is connected to an external air source. The air valve can adjust the flow rate of the gas according to the actual needs of the surgery. When the trachea 13 and the outer tube 4 are connected to an external air source, the smoke and blood generated during the surgery can be sucked out through the outer tube 4.

[0037] Understandably, the ablation probe structure in the above embodiments allows the operator to switch between cutting and separating the lesion, electrocoagulation hemostasis, and aspiration with a single hand during surgical procedures, such as laparoscopic surgery. This eliminates the need for frequent and repeated changes of the electrocautery device, electrocoagulation instrument, and aspiration instrument. Furthermore, cutting, electrocoagulation hemostasis, and aspiration can be completed in the same position without the need for switching by retracting the inner tube. This maintains a clear anatomical view, greatly improves the quality of the surgery, significantly reduces intraoperative bleeding, and saves a lot of valuable surgical time.

[0038] This utility model also provides an ablation electrode dissecter, including the above-described ablation probe structure. In the ablation electrode dissecter of the above embodiments of this utility model, the ablation probe structure includes an inner tube 1, an ablation probe body 2 mounted on the inner tube 1, a mounting portion 3 mounted on the inner tube 1 at one end away from the ablation probe body 2, an outer tube 4 interference-fitted onto the inner tube 1, a connecting portion 5 sleeved on the outer tube 4, and an elastic component disposed between the mounting portion 3 and the connecting portion 5. The mounting portion 3 is provided with a conductive component electrically connected to the inner tube 1. The ablation probe body 2 includes a control portion 201 connected to the inner tube 4 and an electrocoagulation cutting blade 202 connected to the control portion. When the inner tube 1 extends or retracts along the length direction of the outer tube 4 to the outside of the outer tube 4 under the push of the elastic component, the first arcuate surface 203 of the electrocoagulation cutting blade 202 constitutes a cutting surface, and the second arcuate surface 204 of the electrocoagulation cutting blade 202 constitutes an electrocoagulation plane.

[0039] In the above-mentioned ablation electrode dissecter of this utility model, the inner tube 1, which is fitted with the ablation probe body 2, is interference-fitted into the inner tube 4 of the outer tube 4, and the inner tube 1 is electrically connected to the conductive component. The inner tube 1 is in a normally energized state during operation. The elastic component connects the mounting part 3 and the connecting part 5, so that the inner tube 1 extends and retracts along the length direction of the outer tube 4 under the push of the elastic component. That is, when the elastic component is compressed, it pushes the inner tube 1 to extend towards the step surface 402 until the ablation probe body 2 is exposed in the outer tube 4. At this time, the ablation probe body 2, which is in an energized state, can be used for cutting and separating lesion tissue, electrocoagulation, and fumigation. When the elastic component is released, it pushes the inner tube 1 to retract towards the mounting part 3 into the ablation probe body or into the outer tube 4. At this time, the port of the outer tube 4 forms a liquid absorption plane.

[0040] The above are merely embodiments of the ablation probe structure and ablation electrode dissecter of this utility model, and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
