Description

Technical Field

[0001] The present invention belongs to the field of medical auxiliary equipment, and in particular relates to a stable bracket for a Combo Knife cold and hot ablation needle. Background Art

[0002] Kangbo Knife ablation is a minimally invasive surgery commonly used to treat tumors. It combines CT guidance technology to accurately locate lesions and perform ablation treatment. After CT positioning, cold and hot ablation needles are inserted to destroy the lesion tissue to achieve the purpose of treatment.

[0003] However, since the cold and hot ablation needle has a heavy tail, it is easy to fall down due to its own weight after puncture, which will lead to deviation after scanning the fixed position, reduce the positioning accuracy, and increase the operation time. At present, doctors mainly use hemostatic forceps to fix and pull the cold and hot ablation needle to prevent it from falling, but this method has certain hidden dangers:

[0004] 1. The hemostatic forceps are not easy to fix. Every time we try every possible way to fix the puncture needle, it is difficult to achieve the desired effect. The operation time is long, which increases the operation time.

[0005] 2. It is easy to accidentally damage the puncture needle, making the work impossible;

[0006] 3. Hemostatic forceps are made of metal and will produce artifacts during CT scans. The resulting images may affect surgical judgment and are not conducive to use. Summary of the invention

[0007] The purpose of the present invention is to provide a stable bracket for a Kangbo knife cold and hot ablation needle to solve the problem that the tail of the cold and hot ablation needle is heavy, which is easy to tip down due to its own weight after puncture, thereby causing deviation in the determined position after scanning, reducing positioning accuracy and increasing operation time.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A stable bracket for a hot and cold ablation needle of a Conbo knife comprises a base and a stabilizing mechanism, the stabilizing mechanism comprising a stabilizing frame arranged on the top of the base, screws 1 being fixedly installed at both ends of the stabilizing frame, threaded tubes 1 being threadedly connected to two of the screws 1, fixed blocks being fixedly installed on two of the threaded tubes 1, movable rods being movably installed on both sides of the fixed blocks, support rods being movably installed between the bottom of the movable rods and the base, threaded tubes 2 being fixedly installed between the movable rods via reinforcing rods, screws 2 being threadedly installed on the bottom of the threaded tubes 2, and an adjusting rod being movably installed between the screws 2 and the base.

[0010] Preferably, a rotating member 1 is installed between the movable rod and the fixed block, and a rotating member 2 is installed between the base and the support rod and between the base and the adjusting rod.

[0011] Preferably, the stabilizing frame adopts an hourglass-shaped structure.

[0012] Preferably, the reinforcing rod and the threaded tube adopt a Y-shaped structure.

[0013] Preferably, a rotating wheel is fixedly mounted on the first screw and the second screw, and the outer surface of the rotating wheel is provided with anti-slip grooves.

[0014] Preferably, a bottom plate is movably provided inside the base, and the bottom plate passes through the base.

[0015] Preferably, limiting blocks are fixedly installed on both sides of the bottom plate, and limiting grooves are arranged on both sides inside the base, and the limiting grooves are adapted to the movement trajectory of the limiting blocks.

[0016] Preferably, fixing seats are fixedly installed on both sides of the movable rod, balls are movably arranged between the fixing seats and the inner wall of the support rod, and a blocking block is fixedly installed on the inner side of the support rod at the top of the fixing seat.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention places the device at the bottom of the cold or hot ablation needle and then turns any one of the screws to drive the stabilizing frame to move horizontally left and right, so as to fine-tune the position of the stabilizing frame until the stabilizing frame is directly below the cold or hot ablation needle. Turning the second screw drives the stabilizing frame to move vertically up and down, and quickly adjusts the height of the device until the stabilizing frame contacts the cold or hot ablation needle. The cold or hot ablation needle can be supported and fixed, effectively preventing the cold or hot ablation needle from tipping toward the center of the earth due to the heavy needle tail, which may cause deviation after scanning of the fixed position. This facilitates the positioning doctor's operation, reduces the operation time, and improves the success rate of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] As attached Figure 1 To Attachment Figure 4 As shown:

[0029] Embodiment 1: This embodiment provides a stable bracket for a Kangbo knife cold and hot ablation needle, comprising a base 1 and a stabilizing mechanism, the stabilizing mechanism comprising a stabilizing frame 7 arranged on the top of the base 1, screws 6 are fixedly installed at both ends of the stabilizing frame 7, threaded tubes 5 are threadedly connected to two screws 6, fixed blocks 4 are fixedly installed on two threaded tubes 5, movable rods 3 are movably installed on both sides of the fixed blocks 4, support rods 2 are movably installed between the bottom of the movable rods 3 and the base 1, threaded tubes 10 are fixedly installed between the movable rods 3 via reinforcement rods 11, screws 9 are threadedly installed on the bottom of the threaded tubes 10, and an adjusting rod 8 is movably installed between the screws 9 and the base 1.

[0030] After the cold and hot ablation needle is inserted, the device is placed at the bottom of the cold and hot ablation needle. After keeping it stable, the stabilization mechanism is adjusted according to the position of the cold and hot ablation needle, including:

[0031] When any screw 6 is turned, the screw 6 will drive the stabilizing frame 7 to move horizontally left and right through the threaded connection relationship between the screw 6 and the threaded tube 5, so as to fine-tune the position of the stabilizing frame 7 until the stabilizing frame 7 is located directly below the cold and hot ablation needle;

[0032] By turning any one of the screws 29, the screw 29 is movably connected with the adjusting rod 8, so that when it is turned, the screw 29 is connected with the threaded barrel 210 to drive the threaded barrel 210 to move up and down, and the threaded barrel 210 is connected with the movable rod 3 through the reinforcing rod 11, so as to pull the movable rod 3 and the stabilizing frame 7 to move downward, and because the other screw 29 is not turned, the length of the other adjusting rod 8 is fixed, so that it will only pull the movable rod 3 in the corresponding direction to move downward, and then cause the device to tilt in the direction of turning the screw 29, thereby driving the stabilizing frame 7 to move horizontally forward and backward, so as to adjust the contact position between the stabilizing frame 7 and the cold and hot ablation needle, so that it can stably contact with the needle tail and the support is more stable;

[0033] By turning the two screws 9 at the same time, the stabilizing frame 7 can be driven to move vertically up and down, and the height of the device can be quickly adjusted until the stabilizing frame 7 contacts the cold and hot ablation needles, thereby improving efficiency and facilitating use by personnel;

[0034] It can effectively prevent the cold and hot ablation needles from tipping toward the center of the earth due to the heavy needle tail, resulting in deviations in the determined position after scanning. It facilitates the positioning doctor's operation, reduces the operation time, and improves the success rate of the operation.

[0035] Specifically, a rotating member 12 is installed between the movable rod 3 and the fixed block 4 , and a rotating member 2 13 is installed between the base 1 and the support rod 2 and between the base 1 and the adjusting rod 8 .

[0036] Specifically, the stabilizing frame 7 adopts an hourglass-shaped structure.

[0037] Specifically, the reinforcing rod 11 and the threaded tube 10 adopt a Y-shaped structure.

[0038] Specifically, a rotating wheel 14 is fixedly mounted on the screw 1 6 and the screw 2 9 , and an outer surface of the rotating wheel 14 is provided with anti-slip grooves.

[0039] Specifically, fixed seats 301 are fixedly installed on both sides of the movable rod 3, balls 302 are movably arranged between the fixed seats 301 and the inner wall of the support rod 2, and a blocking block 201 is fixedly installed on the inner side of the support rod 2 at the top of the fixed seats 301.

[0040] As can be seen from the above, by designing the stabilizing frame 7 to be thick at both ends and thin in the middle with an arc-shaped hourglass structure, its arc shape is adapted to the shape of the cold and hot ablation needle, so that it can be stably supported and fixed after contact and engagement, and will not be affected by the staff rotating the screw 6 to drive the stabilizing frame 7 to rotate synchronously and cause the angle change, and no secondary adjustment is required, so that the device can stably support the cold and hot ablation needle at any angle, reducing the threshold for use;

[0041] By adopting a Y-shaped structure for the reinforcing rod 11 and the threaded tube 10, the movable rod 3 can be triangularly supported to improve stability;

[0042] The rotating wheel 14 can increase the contact area between the operator's fingers and the screw, and the anti-slip pattern can increase the contact friction, making it easier for the operator to drive it to rotate for adjustment;

[0043] By setting the ball 302 on the movable rod 3, the friction resistance between the movable rod 3 and the support rod 2 is reduced when the movable rod 3 moves, so that when the staff turns the screw 29 to adjust the height, the movable rod 3 can slide into the support rod 2 at the first time, thereby improving the operating efficiency and facilitating the use of personnel.

[0044] Embodiment 2: This embodiment provides a stable bracket for hot and cold ablation needles of a Kangbo knife, including a base 1 and a stabilizing mechanism, the stabilizing mechanism including a stabilizing frame 7 arranged on the top of the base 1, screws 6 are fixedly installed at both ends of the stabilizing frame 7, threaded tubes 5 are threadedly connected to two screws 6, fixed blocks 4 are fixedly installed on two threaded tubes 5, movable rods 3 are movably installed on both sides of the fixed blocks 4, support rods 2 are movably installed between the bottom of the movable rods 3 and the base 1, threaded tubes 10 are fixedly installed between the movable rods 3 via reinforcement rods 11, screws 9 are threadedly installed on the bottom of the threaded tubes 10, and an adjusting rod 8 is movably installed between the screws 9 and the base 1.

[0045] After the cold and hot ablation needle is inserted, the device is placed at the bottom of the cold and hot ablation needle. After keeping it stable, the stabilization mechanism is adjusted according to the position of the cold and hot ablation needle, including:

[0046] When any screw 6 is turned, the screw 6 will drive the stabilizing frame 7 to move horizontally left and right through the threaded connection relationship between the screw 6 and the threaded tube 5, so as to fine-tune the position of the stabilizing frame 7 until the stabilizing frame 7 is located directly below the cold and hot ablation needle;

[0047] By turning any one of the screws 29, the screw 29 is movably connected with the adjusting rod 8, so that when it is turned, the screw 29 is connected with the threaded barrel 210 to drive the threaded barrel 210 to move up and down, and the threaded barrel 210 is connected with the movable rod 3 through the reinforcing rod 11, so as to pull the movable rod 3 and the stabilizing frame 7 to move downward, and because the other screw 29 is not turned, the length of the other adjusting rod 8 is fixed, so that it will only pull the movable rod 3 in the corresponding direction to move downward, and then cause the device to tilt in the direction of turning the screw 29, thereby driving the stabilizing frame 7 to move horizontally forward and backward, so as to adjust the contact position between the stabilizing frame 7 and the cold and hot ablation needle, so that it can stably contact with the needle tail and the support is more stable;

[0048] By turning the two screws 9 at the same time, the stabilizing frame 7 can be driven to move vertically up and down, and the height of the device can be quickly adjusted until the stabilizing frame 7 contacts the cold and hot ablation needles, thereby improving efficiency and facilitating use by personnel;

[0049] It can effectively prevent the cold and hot ablation needles from tipping toward the center of the earth due to the heavy needle tail, resulting in deviations in the determined position after scanning. It facilitates the positioning doctor's operation, reduces the operation time, and improves the success rate of the operation.

[0050] Specifically, a rotating member 12 is installed between the movable rod 3 and the fixed block 4 , and a rotating member 2 13 is installed between the base 1 and the support rod 2 and between the base 1 and the adjusting rod 8 .

[0051] Specifically, the stabilizing frame 7 adopts an hourglass-shaped structure.

[0052] Specifically, the reinforcing rod 11 and the threaded tube 10 adopt a Y-shaped structure.

[0053] Specifically, a rotating wheel 14 is fixedly mounted on the screw 1 6 and the screw 2 9 , and an outer surface of the rotating wheel 14 is provided with anti-slip grooves.

[0054] Specifically, a bottom plate 101 is movably provided inside the base 1 , and the bottom plate 101 passes through the base 1 .

[0055] Specifically, limiting blocks 103 are fixedly installed on both sides of the bottom plate 101 , and limiting grooves 102 are arranged on both sides inside the base 1 . The limiting grooves 102 are adapted to the movement trajectory of the limiting blocks 103 .

[0057] As can be seen from the above, the base 1 will support and fix the entire device. If necessary, the bottom plate 101 can be pulled out from the base 1 to increase the contact area between the base 1 and the bottom support and improve its own stability. For example, when the height of the device is adjusted to the highest and the center of gravity moves upward and instability may occur, the scope of application of the device is increased.
