Description

Technical Field

[0001] The utility model specifically relates to a lung microwave ablation needle. Background Art

[0002] A microwave ablation needle is a device that can transmit microwave energy in local tissues and cause the tissues to coagulate. Microwave ablation needles are widely used in tumor treatment and can effectively inhibit the spread of tumor cells. They are used by puncturing the tumor with the microwave ablation needle under the guidance of imaging equipment such as B-ultrasound or CT. The polar molecules in the tissue move at high speed under the action of the microwave field, and rub against each other to generate heat, thereby rapidly heating up the tumor. When the temperature rises to about 60 degrees Celsius, the cancer cell proteins denature and coagulate, causing irreversible necrosis, thereby inactivating tumor cells and achieving a therapeutic effect.

[0003] When existing microwave ablation needles are used for lung tumor ablation, since it is a slow and continuous treatment process, the doctor needs to hold the ablation needle in his hand until the end of the treatment, which not only affects the doctor's operation, but also causes arm soreness and tremors for a long time, which not only causes discomfort to the doctor but may also have a certain impact on the treatment. Therefore, there is a need for a microwave ablation needle that is easy to use and does not require the doctor to hold the needle in his hand during treatment.

[0004] In Chinese patent: 202221577237.2, the name is: A tumor ablation needle fixing bracket for surgery, which records that it includes an ablation needle assembly, characterized in that: the ablation needle assembly includes a syringe, a sliding ring is provided on the outside of the syringe, and a fixing frame assembly is provided on the outside of the sliding ring. The fixing frame assembly includes a telescopic support rod, a fixing strap, a connecting rod, a support plate and a fixing ring. There are three telescopic support rods and they are equidistantly installed on the outside of the sliding ring.

[0005] As shown in the attached figure of patent 202221577237.2, this patent mainly utilizes a fixing frame assembly in conjunction with a locking piece to support and fix the ablation needle assembly when in use, and can also arbitrarily adjust the support angle through the cooperation between three telescopic support rods, making it more convenient for doctors to use. This patent can structurally fix and support the ablation needle, but the structure is relatively complex, and the operation is complicated and inconvenient to use when adjusting the position and angle of the ablation needle. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the existing microwave ablation needle mentioned in the background technology has no supporting and fixing ability when in use, needs to be held by a doctor, and the position and angle of the existing microwave ablation needle are inconvenient to adjust.

[0007] In view of the above technical problems, a lung microwave ablation needle is proposed; it is achieved by the following technical scheme: a lung microwave ablation needle, comprising an ablation needle, characterized in that: a corrugated cable can be detachably connected to the handle of the ablation needle, and the other end of the corrugated cable is connected to a power supply.

[0008] Preferably, the pulmonary microwave ablation needle further comprises a mounting assembly, and the corrugated cable connected to the ablation needle is fixed on the bed through the mounting assembly. Such a configuration facilitates the fixation of the ablation needle and also facilitates the adjustment of the position of the ablation needle as needed, thereby facilitating puncture of different parts.

[0012] Preferably, the limit assembly is arranged inside the slider, including a limit plate with a limit block and an unlocking button. The unlocking button is arranged on the limit plate and partially exposes the slider for user operation. The limit block is stuck in the limit groove on the slide rod. Pressing the unlocking button can move the limit block out of the limit groove, thereby releasing the limit of the slider position by the limit assembly. Such an arrangement facilitates the adjustment of the position of the corrugated cable and facilitates the puncture of different positions of the ablation needle.

[0013] Preferably, a clamp disassembly assembly for controlling the disassembly of a clamp on the corrugated cable is provided in the slider. The disassembly clamp is inserted into a clamp installation groove on the slider.

DETAILED DESCRIPTION

[0025] The following will be combined with the attached embodiment of the utility model Figure 1-6 , the technical solutions in the embodiments of the utility model are described in detail. Example

[0026] like Figure 1 and 5 As shown, a lung microwave ablation needle includes an ablation needle 2, a corrugated cable 3 and a mounting assembly 4. One end of the ablation needle 2 is detachably connected to the corrugated cable 3, and the other end of the corrugated cable 3 is connected to a power source and is also provided with a disassembly clamp 34. The corrugated cable 3 connected with the ablation needle 2 can be connected to the mounting assembly 4 through the disassembly clamp 34, and the mounting assembly 4 is fixed on the bed 1.

[0027] The ablation needle 2 includes a needle 21 and a handle 22. The needle 21 is arranged on the handle 22. In order to facilitate the disassembly and assembly of the ablation needle 2 and the corrugated cable 3, a cable slot 23 connected to the corrugated cable 3 for powering the ablation needle 2 is also provided on the handle 22. The cable plug 33 at one end of the corrugated cable 3 is inserted into the cable slot 23.

[0028] like Figure 1 , 2 As shown in FIG. 3 , the corrugated cable 3 is composed of multiple layers, the innermost layer being a power cord 35 for power supply, an inner core tube 31 covering the outside of the power cord 35 , a reinforcement layer 32 being arranged outside the inner core tube 31 , and reinforcement ribs 36 being spirally arranged on the surface of the reinforcement layer 32 .

[0029] The inner core tube 31 is a cylindrical hollow tube with openings at both ends. The power cord 35 is inserted into the inner core tube 31, filling the internal cavity of the inner core tube 31, and no relative displacement can occur between the power cord 35 and the inner core tube 31. One end of the power cord 35 is flush with the inner core tube 31, and the other end extends a section and is connected to the power supply. In order to ensure the overall strength of the corrugated cable 3 and facilitate the bending of the corrugated cable 3, the inner core tube 31 is made of a material that can be bent and has a certain strength, such as copper or aluminum alloy. The present embodiment preferably uses copper with good flexibility and toughness as the raw material to manufacture the hollow inner core tube 31, and the tube wall of the inner core tube 31 will not break, be squeezed or deformed when the inner core tube 31 is bent.

[0030] In order to further strengthen the strength of the inner core tube 31, protect the inner core tube 31 and prevent the inner core tube 31 from being damaged and deformed during bending, a reinforcing layer 32 is provided on the outside of the inner core tube 31. The reinforcing layer 32 is made of a plastic with certain strength and plasticity. Polycarbonate (PC) is preferably used in this embodiment. The reinforcing layer 32 covers the outside of the inner core tube 31 and has the same length as the inner core tube 31. There is no relative displacement between the reinforcing layer 32 and the inner core tube 31. The reinforcing layer 32 improves the strength of the inner core tube 31 while protecting the inner core tube 31 to prevent the inner core tube 31 from oxidation and rust in the air, thereby improving the service life.

[0031] In order to strengthen the overall strength of the corrugated cable 3 and improve the fixing and supporting ability of the corrugated cable 3 to the ablation needle 2, reinforcing ribs 36 are arranged on the outside of the reinforcing layer 32. The reinforcing ribs 36 are spirally wound on the outer surface of the reinforcing layer 32, and the cross-section of the reinforcing ribs 36 is trapezoidal. Such an arrangement improves the overall strength of the corrugated cable 3 and improves the fixing and supporting ability of the corrugated cable 3 to the ablation needle 2, thereby effectively preventing the corrugated cable 3 from deforming when subjected to force.

[0032] In order to further improve the effect of the reinforcing rib 36, the reinforcing rib 36 can be made of copper, and a layer of flexible plastic is coated on the outside of the reinforcing rib 36 to prevent the reinforcing rib 36 from rusting. The reinforcing rib 36 is integrally arranged with the reinforcing layer 32, and the two ends of the reinforcing rib 36 are flush with the two ends of the reinforcing layer 32.

[0033] The arrangement of the inner core tube 31 , the reinforcement layer 32 and the reinforcement ribs 36 can significantly improve the strength of the corrugated cable 3 , so that the corrugated cable 3 can support the ablation needle 2 after being bent.

[0034] In order to facilitate the connection between the corrugated cable 3 and the ablation needle 2, a cable plug 33 is provided at one end of the corrugated cable 3. The cable plug 33 is connected to the power line 35 in the corrugated cable 3. The cable plug 33 is fixed on the corrugated cable 3. The cable plug 33 can be connected to the cable slot 23 on the handle 22 of the ablation needle 2 to realize power supply to the ablation needle 2.

[0035] In order to facilitate fixing the ablation needle 2 on the bed 1 , a disassembly and assembly clamp 34 is provided at the other end of the corrugated cable 3 , and the disassembly and assembly clamp 34 is fixed on the corrugated cable 3 via a fixing ring 37 .

[0036] The fixing ring 37 is a cylindrical hollow tube with openings at both ends. The fixing ring 37 is sleeved on the end of the corrugated cable 3, and no relative displacement occurs between the two. The power cord 35 extending from the corrugated cable 3 passes through the fixing ring 37. The disassembly and assembly clamp 34 is a metal rod with a rectangular cross-section. One end of the disassembly and assembly clamp 34 is welded to the outer wall of the fixing ring 37, and the other end is inserted into the clamp mounting groove 43 on the slider 41. At the same time, in order to facilitate the fixing of the position of the disassembly and assembly clamp 34, a locking slot for inserting a locking plug 51 is opened on the surface of the disassembly and assembly clamp 34.

[0037] Regarding the process of fixing the ablation needle 2 with the corrugated cable 3: when in use, first install the corrugated cable 3 on the bed 1, then manually bend the corrugated cable 3 according to the position of the ablation needle 2, and then connect the corrugated cable 3 to the ablation needle 2, so that the position of the ablation needle 2 can be fixed and supported by the corrugated cable 3.

[0038] like Figure 1 , 4 As shown in Figures 5 and 6, the mounting assembly 4 includes a slider 41 and a slide bar 42. The slide bar 42 is fixed to the side of the bed 1. The slider 41 is mounted on the slide bar 42. The slider 41 can slide freely along the slide bar 42. At the same time, the slider 41 can be fixed on the slide bar 42. In order to switch the installation position of the ablation needle 2 and facilitate the ablation needle 2 to puncture different positions, the mounting assembly 4 is arranged on both the left and right sides of the bed 1.

[0039] The slide bar 42 is a strip metal plate with a rectangular cross-section. The slide bar 42 is fixed to the side of the bed body 1 parallel to the bed body 1 by screws. Two side plates are welded at both ends of the slide bar 42 perpendicular to the surface of the slide bar 42. Two limit rods 44 are fixed to the side plates in parallel by screws, and there is a certain interval between the two limit rods 44.

[0040] The limiting rod 44 is a strip-shaped metal rod with a square cross-section, and in order to facilitate the fixation of the slider 41, a plurality of limiting grooves 45 are provided on the inner side surface of the upper limiting rod 44 at intervals perpendicular to the limiting rod 44, and the limiting block 64 on the limiting assembly 6 is stuck in the limiting groove 45.

[0041] Definition: With the bed 1 as the reference, the direction pointing to the ground is downward, and the other direction opposite to it is upward.

[0042] The slider 41 is a hollow metal block with an "E"-shaped cross-section. The two rectangular grooves on the slider 41 correspond to the positions of the limit rod 44. The limit rod 44 can be stably stuck in these grooves to limit the position of the slider 41, so that the slider 41 can slide along the slide rod 42 while the slider 41 can effectively fall off the slide rod 42. In order to limit the position of the slider 41, a functional hole corresponding to the upper limit groove 45 of the limit rod 44 is opened on the groove at the upper end of the slider 41. The limit block 64 on the limit component 6 can pass through this functional hole and be stuck in the limit groove 45.

[0043] A limit assembly 6 is installed in the upper cavity of the slider 41, and the position of the slider 41 on the slide rod 42 can be limited by the limit assembly 6. A clamping head disassembly assembly 5 is installed in the lower cavity of the slider 41, and the fixation of the corrugated cable 3 on the slider 41 can be controlled by the clamping head disassembly assembly 5. The corrugated cable 3 can be quickly disassembled and assembled on the slider 41 through the clamping head disassembly assembly 5.

[0044] like Figure 4 and 5 As shown, the limiting assembly 6 includes a limiting plate 61 , an unlocking button 62 , a second return spring 63 and a limiting block 64 .

[0045] The limit plate 61 is a rectangular plate, which is inserted into the cavity at the upper end of the slider 41. The upper end surface of the limit plate 61 is flush with the upper surface of the slider 41. The surface of the limit plate 61 near the lower end is perpendicular to the outer convexity of the limit plate 61 and is welded with multiple limit blocks 64 at intervals. The positional relationship between the limit blocks 64 corresponds to the limit groove 45 on the limit rod 44. The limit block 64 on the limit plate 61 can be stuck in the limit groove 45 through the functional hole on the slider 41.

[0046] The second return spring 63 is arranged on the back side of the limit plate 61, one end of which is connected to the limit plate 61 and the other end is connected to the inner wall of the slider 41. Under the action of the second return spring 63, the limit block 64 on the limit plate 61 is clamped in the limit groove 45 through the functional hole on the slider 41 to limit the position of the slider 41.

[0047] In order to unlock the position of the slider 41 , an unlocking button 62 is fixed above the limiting plate 61 , and a portion of the unlocking button 62 is exposed outside the slider 41 for user operation, and the length of the exposed portion of the unlocking button 62 is greater than the size of the limiting block 64 .

[0048] Regarding the limiting and unlocking process of the slider 41 by the limiting component 6: when the position of the slider 41 needs to be moved, the position of the slider 41 is first unlocked, and the unlocking button 62 is pressed when unlocking. At this time, the unlocking button 62 drives the limiting plate 61 to move. At this time, the second return spring 63 connected to the limiting plate 61 is compressed, and at the same time, the limiting block 64 is moved out of the limiting groove 45. At this time, the slider 41 can be moved. After moving to the appropriate position, release the unlocking button 62. At this time, the second return spring 63 resets and pushes the limiting plate 61 to move, and then the limiting block 64 is stuck in the limiting groove 45 to complete the adjustment of the position of the slider 41.

[0049] like Figure 5 and 6 As shown, the clamp disassembly assembly 5 includes a locking plug 51 , an unlocking rod 52 , an unlocking gear 53 and an unlocking cap 57 .

[0050] The locking plug 51 is a metal plate with a rectangular cross-section. A rack 54 is provided on the side of the locking plug 51. The locking plug 51 is arranged in a cavity at the lower end of the slider 41, and one end of the locking plug 51 is inserted into the clamp mounting groove 43 on the slider 41 and inserted into the locking slot on the disassembly clamp 34. The other end is connected to a first return spring 55. The other end of the first return spring 55 is against the sealing plate 56 at the lower end of the closed slider 41. Under the action of the first return spring 55, the locking plug 51 is always inserted in the locking slot.

[0051] The unlocking rod 52 is a metal plate with a rectangular cross-section. A rack 54 is arranged on the side of the unlocking rod 52. The unlocking rod 52 is arranged in a cavity at the lower end of the slider 41 and is distributed parallel to the locking plug 51. One end of the unlocking rod 52 passes through the sealing plate 56 and is connected to the unlocking cap 57, and the other end is connected to a third return spring 58 connected to the slider 41.

[0052] An unlocking gear 53 is installed in the cavity at the lower part of the slider 41. The unlocking gear 53 is arranged in the middle of the locking plug 51 and the unlocking rod 52, and is respectively engaged with the racks 54 on the locking plug 51 and the unlocking rod 52. When the unlocking cap 57 is pressed, the unlocking rod 52 will drive the unlocking gear 53 to rotate, and then drive the locking plug 51 to move out of the locking slot, thereby releasing the locking plug 51 from the limit of the disassembly and assembly head 34.

[0053] In order to facilitate the fixation of the corrugated cable 3, the locking plug 51 locks the disassembly clamp 34, and the end faces of the locking plug 51 and the disassembly clamp 34 are rounded. In this way, when the locking plug 51 is inserted into the clamp installation groove 43, the arc end face of the disassembly clamp 34 squeezes the arc end face of the locking plug 51, and the locking plug 51 automatically shrinks, making it convenient for the disassembly clamp 34 to be fully inserted into the clamp installation groove 43.

[0054] Regarding the use process of the clamp head disassembly and assembly component 5: when the corrugated cable 3 needs to be installed, the locking plug 51 is directly inserted into the clamp head installation groove 43. At this time, the arc end surface of the disassembly clamp head 34 squeezes the arc end surface of the locking plug 51, and the locking plug 51 automatically contracts, and the first return spring 55 is compressed. When the disassembly clamp head 34 is fully inserted into the clamp head installation groove 43, the locking plug 51 is inserted into the locking slot on the disassembly clamp head 34 under the action of the first return spring 55, and the installation of the corrugated cable 3 is completed; when the corrugated cable 3 needs to be disassembled, the unlocking cap 57 is pressed to drive the unlocking The locking rod 52 moves, thereby driving the unlocking gear 53 to rotate. At this time, the third return spring 58 is compressed. When the unlocking gear 53 rotates, the unlocking gear 53 can drive the locking plug 51 to move in the opposite direction of the unlocking rod 52, and the locking plug 51 is removed from the locking slot, releasing the limit of the locking plug 51 on the disassembly and assembly clamp 34. At this time, the first return spring 55 is compressed, and the disassembly and assembly clamp 34 can be pulled out, and then the unlocking cap 57 is loosened. At this time, under the action of the first return spring 55 and the third return spring 58, the locking plug 51 and the unlocking rod 52 are reset, completing the disassembly of the corrugated cable 3.

[0055] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
