Description

Technical Field

[0001] The invention relates to the technical field of gold mark implantation devices, in particular to a removable gold mark implantation device for positioning human body radiotherapy. Background Art

[0002] Human radiotherapy is the use of radiation as a way to treat diseases. A common treatment method is CyberKnife. Before CyberKnife removes tumor lesions, in order to enable CyberKnife to accurately locate the tumor site, a metal marker with radioactive particles is usually implanted into the body before treatment begins after pathological examination. This is usually a metal with high stability. When the gold marker is implanted into the body, it needs to be operated through a specific implant device.

[0003] However, when the existing gold label implantation device is installed into the device, due to the small size of the gold label and the outer diameter of the gold label is usually smaller than the inner diameter of the puncture structure of the device, after the gold label is installed into the puncture structure, in order to prevent the gold label from accidentally slipping out from the end port of the puncture structure during puncture, it is usually necessary to seal the end port of the puncture structure with bone wax. These steps make the process of installing the gold label into the device more cumbersome and time-consuming; secondly, when the gold label is implanted into the tumor in the body through the implantation device, since the implantation device needs to puncture the skin and tissue to enter the target tumor, and the contact point between the implantation device and the skin is only the outer surface of the puncture structure on the device, when the implantation device pushes the gold label into the body, the puncture structure of the device is easy to slip along The gold label moves inward or outward along the skin, causing the implantation point of the gold label to shift easily, which is not conducive to accurately implanting the gold label into the set tumor point. In addition, since the gold label is a radioactive particle, it has a certain radiation effect on the human body. After completing radiotherapy, if the gold label does not decay normally, it needs to be removed from the body. The existing removal method is to pull it out through the medical thread connected to the end of the gold label. During operation, since the micro-injury when the gold label was implanted has healed, the medical thread outside the body is easily blocked by the healing tissue and is not easy to pull out. In addition, the thread is easily broken when brute force is used to pull it, which can easily move the gold label to other tissues in the body, making it more difficult to remove the gold label, and is not conducive to removing the gold label from the body. Summary of the invention

[0004] The object of the present invention is to provide a removable human body radiotherapy positioning gold label implantation device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a removable human radiotherapy positioning gold mark implantation device, comprising a card cover, a card column movably penetrates the inner side of the card cover, a first through tube penetrates one end of the card column, an ear plate is fixedly connected to the other end of the card column, a card rod movably penetrates the middle of the ear plate, a top end of the card rod is fixedly connected to a top tube, a micro air pump is fixedly installed inside the top tube, a second through tube penetrates the bottom end of the card rod, a channel is opened inside the card rod, a thin rod is fixedly connected to the bottom end of the top tube, a round plate is fixedly connected to the end of the thin rod, a puncture needle penetrates the middle of one side wall of the card cover, a suction cup is provided in the middle of the puncture needle, a clip is movably connected to one side wall of the suction cup, and a hoop is provided on the outside of the clip.

[0006] Preferably, a through hole is opened on one side wall of the ear plate, the thin rod is movably connected to the ear plate through the through hole, and the circular plate is movably connected to the ear plate through the thin rod.

[0007] Preferably, the first through tube is movably connected to the puncture needle through a clamping column, and the second through tube is movably connected to the first through tube through a clamping rod.

[0008] Preferably, a metal marker is movably connected inside the first through tube, and the metal marker is movably connected to the puncture needle through the first through tube and the second through tube.

[0009] Preferably, an air outlet is provided on the outer wall of the top tube, and the output end of the micro air pump is connected to the air outlet.

[0010] Preferably, a notch is formed on the outer wall of the clip, and the clip is movably connected to the puncture needle via the notch.

[0011] Preferably, the top end of the clip is fixedly connected to a top plate, and the hoop is movably connected to the clip via the top plate.

[0012] Preferably, the suction cup is movably connected to the puncture needle via a clip.

[0013] Preferably, the channel is communicated with an input end of the micro air pump, and the channel is communicated with the interior of the second through tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The removable human radiotherapy positioning gold label implantation device uses a micro air pump, a channel and a second through tube, so that the inside of the device's puncture structure can draw out the airflow in the second through tube through the micro air pump and the channel, so that negative pressure is generated at the tube mouth of the second through tube, so that the top of the gold label can be sucked tightly to the end of the second through tube through the negative pressure, thereby eliminating the step of sealing the end of the puncture structure with bone wax and saving the time required to install the gold label into the device.

[0016] 2. This removable human radiotherapy positioning gold label implant device uses a suction cup, a clip and a hoop to increase the area where the implant device contacts the human skin. After the puncture structure of the implant device penetrates into a set point in the body, the clip can be locked by the hoop to fix the puncture structure to the suction cup close to the skin, making it difficult for the puncture structure of the device to move inward or outward, thereby enhancing the stability of the implant device when implanting the gold label, reducing the probability of the gold label implantation point being offset, and being more conducive to accurately implanting the gold label into the set tumor point.

[0017] 3. This removable human radiotherapy positioning gold mark implant device uses the first through tube, the thin rod and the round plate. When the gold mark needs to be removed from the body, the implant device can be reinserted into the body, and then the negative pressure generated by the second through tube is used to suck the top of the gold mark tightly. Then, the end of the second through tube together with the gold mark can be pulled into the first through tube through the limit prompts of the thin rod and the round plate. When the gold mark is removed, it can be removed out of the body simultaneously with the withdrawal of the device, reducing the obstruction of human tissue to the removal of the gold mark, reducing the difficulty of removing the gold mark, and thus more conducive to the removal of the gold mark from the body.

[0028] like Figures 1 to 6As shown, the removable human radiotherapy positioning gold label implantation device of this embodiment includes a card cover 6. The interior of the card cover 6 is a hollow structure, and its function is to increase the volume of the end of the puncture needle 7 to prevent the puncture needle 7 from completely piercing the body. At the same time, it is convenient for medical personnel to hold the puncture needle 7 and to maintain the connection with the card column 5. The inner side of the card cover 6 is movably penetrated by the card column 5. The function of the card column 5 is to increase the volume of the end of the first through tube 9, so that the first through tube 9 can enter the puncture needle 7 after being inserted into the card cover 6. One end of the first card column 5 is penetrated by the first through tube 9. The function of the first through tube 9 is to provide space for the second through tube 10 to move in the puncture needle 7. The other end of the card column 5 is fixedly connected to the ear plate 4, and the middle part of the ear plate 4 is movably penetrated by the card rod 2 The top of the clamping rod 2 is fixedly connected with a top tube 1. The function of the top tube 1 is to increase the volume of the end of the second through tube 10, so as to facilitate pushing the second through tube 10 into the first through tube 9 and to protect the micro air pump 19. The micro air pump 19 is fixedly installed inside the top tube 1. The function of the micro air pump 19 is to generate negative pressure in the second through tube 10, so as to facilitate the end of the second through tube 10 to suck one end of the gold mark tightly, so as to facilitate the gold mark to maintain better stability at the end of the first through tube 9. The bottom end of the clamping rod 2 is penetrated by the second through tube 10. The outer diameter of the second through tube 10 is adapted to the inner diameter of the first through tube 9, so that the gold mark can be sucked into the first through tube 9 under the adsorption of the second through tube 10 and protected, so as to facilitate the gold mark to be punctured. The needle 7 is pulled out and removed from the body. A channel 20 is opened inside the card rod 2. The function of the channel 20 is to connect the second through tube 10 and the input end of the micro air pump 19, so that the air in the second through tube 10 can be sucked away by the micro air pump 19. The bottom end of the top tube 1 is fixedly connected with a thin rod 3. The function of the thin rod 3 is to facilitate medical personnel to observe the distance of the card rod 2 being pulled out, thereby facilitating the control of the distance between the end of the second through tube 10 and the end of the first through tube 9, so that the gold label is easier to be pushed out or inhaled from the first through tube 9. The end of the thin rod 3 is fixedly connected with a circular plate 18. The circular plate 18 limits the distance between the ear plate 4 and the top tube 1, so that the top tube 1 and the ear plate 4 can remain connected. A through hole is passed through the middle of one side wall of the card cover 6. The puncture needle 7 has a hollow structure inside, and the inner diameter of the puncture needle 7 is matched with the outer diameter of the first through tube 9, so as to facilitate the first through tube 9 to pass out of the puncture needle 7. A suction cup 8 is provided in the middle of the puncture needle 7. The surface of the suction cup 8 is smooth and can be close to the skin, so as to achieve the fixation of the implant device on the body surface, which is more conducive to the implantation of the gold mark in the body. A side wall of the suction cup 8 is movably connected with a clip 13. There are multiple clips 13, and they are all around the outer wall of the puncture needle 7. At the same time, the surface of the clip 13 is rough, which is conducive to increasing the friction between the clip 13 and the puncture needle 7. A hoop 16 is provided on the outside of the clip 13. The function of the hoop 16 is to clamp the clip 13 tightly on the surface of the puncture needle 7, so as to achieve the fixation of the puncture needle 7 and the suction cup 8.

[0029] Specifically, a through hole 17 is opened on one side wall of the ear plate 4, and the thin rod 3 is movably connected to the ear plate 4 through the through hole 17, and the circular plate 18 is movably connected to the ear plate 4 through the thin rod 3. The inner diameter of the through hole 17 is larger than the outer diameter of the thin rod 3, so that the ear plate 4 is subject to less friction from the thin rod 3 when sliding along the thin rod 3, thereby facilitating the withdrawal of the second through tube 10 in the first through tube 9.

[0030] Furthermore, the first through tube 9 is movably connected to the puncture needle 7 through the clamping column 5, and the second through tube 10 is movably connected to the first through tube 9 through the clamping rod 2. The cooperation between the second through tube 10 and the first through tube 9 can enable the metal marker 11 to be smoothly loaded into the implant device, or pushed out from the implant device, thereby facilitating the operation and use by medical staff.

[0031] Furthermore, a metal marker 11 is movably connected inside the first through tube 9, and the metal marker 11 is movably connected to the puncture needle 7 through the first through tube 9 and the second through tube 10. The diameter of the metal marker 11 is larger than the inner diameter of the second through tube 10, so that the metal marker 11 is not easily sucked into the second through tube 10, thereby reducing the interference caused by the metal marker 11 being implanted in the body.

[0032] Furthermore, an air outlet 12 is provided on the outer wall of the top tube 1, and the output end of the micro air pump 19 is connected to the air outlet 12. The function of the air outlet 12 is to enable the micro air pump 19 to operate normally, so that the micro air pump 19 can smoothly extract the gas in the second through pipe 10, so that the pipe mouth of the second through pipe 10 is in a negative pressure state.

[0033] Furthermore, a notch 15 is provided on the outer wall of the clip 13, and the clip 13 is movably connected to the puncture needle 7 through the notch 15. The function of the notch 15 is to allow the clips 13 to be gathered together at a close distance, thereby facilitating the clip 13 to be in close contact with the outer wall of the puncture needle 7, thereby achieving the fixation of the suction cup 8 and the puncture needle 7.

[0034] Furthermore, the top end of the clip 13 is fixedly connected to a top plate 14, and a hoop 16 is movably connected to the clip 13 through the top plate 14. The function of the top plate 14 is to limit the range of up and down sliding of the hoop 16, so that the hoop 16 is not easily accidentally separated from the clip 13. A locking screw is provided on the hoop 16. By tightening the locking screw, the radius of the hoop 16 is reduced, so that the hoop 16 squeezes the clip 13 toward the outer wall of the puncture needle 7, thereby achieving the clamping of the clip 13 by the hoop 16.

[0035] Furthermore, the suction cup 8 is movably connected to the puncture needle 7 through the clip 13. After the suction cup 8 is in close contact with the skin on the body surface, it can increase the contact area between the implant device and the body surface, thereby facilitating the subsequent fixation of the puncture needle 7 on the body surface, so that the device maintains better stability when the gold mark is implanted.

[0036] Furthermore, the channel 20 is communicated with the input end of the micro air pump 19, and the channel 20 is communicated with the interior of the second through tube 10. The channel 20 enables the micro air pump 19 to suck the air in the second through tube 10, so that negative pressure is generated at the end of the second through tube 10, which will tighten the gold mark end at the end of the puncture needle 7, thereby facilitating the gold mark to remain stable after being loaded into the device, eliminating the step of sealing the end of the puncture needle 7 with bone wax.

[0037] The method of using the present embodiment is as follows: when using the removable human radiotherapy positioning gold label implantation device, the suction cup 8 can be first fixed on the skin of the body surface where the puncture is required, and then the micro air pump 19 is connected to the built-in power supply, so that the micro air pump 19 draws out the air in the second through tube 10 through the channel 20 and discharges it from the air outlet 12, and then the metal marker 11 is pushed in from the end of the puncture needle 7. At this time, the metal marker 11 will be retracted into the puncture needle 7 under the adsorption of the second through tube 10, and then the puncture needle 7 can be passed through the middle of the clip 13 in the suction cup 8, so that the puncture needle 7 pierces the skin and tissue to enter the tumor position in the body. When the end of the puncture needle 7 reaches the puncture point through interventional ultrasound, the locking screw on the hoop 16 can be tightened so that the hoop 16 clamps the clip 13 on the outer wall of the puncture needle 7, so that the puncture needle 7 is fixed on the skin of the body surface through the suction cup 8, so that the end of the puncture needle 7 is not easy to move at the set puncture point, and then the ear plate 4 can be pushed so that the clamping column 5 pushes the first through tube 9 and the second through tube 10 outward at the same time, and the power supply of the micro air pump 19 is cut off at the same time. At this time, the metal marker 11 located at the end of the first through tube 9 and the second through tube 10 will be pushed out from the end of the puncture needle 7, so that the metal marker 11 is implanted into the tumor;

[0038] When the metal marker 11 needs to be removed, after the puncture needle 7 and the ends of the first tube 9 and the second tube 10 have all entered the tumor, and the end of the second tube 10 is in contact with one end of the metal marker 11, the micro air pump 19 is started so that the micro air pump 19 draws out the gas in the second tube 10, so that one end of the metal marker 11 is again tightly attached to the end of the second tube 10, and then the top tube 1 can be pulled outward so that the second tube 10 and the metal marker 11 are pulled into the first tube 9, and then the first tube 9 is pulled into the puncture needle 7, and finally the puncture needle 7 can be pulled out so that the metal marker 11 is pulled out together, thus completing the use of the implant device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
