Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to an iodine particle implanter. Background Art

[0002] Iodine seed implantation therapy is a method of radiotherapy for tumors, an effective technology for comprehensive treatment of malignant tumors, and a type of close-range radiotherapy. It is a treatment method that, under the guidance of CT, ultrasound and other images, iodine-125 particles that emit low-energy gamma rays are directly implanted into the tumor or into tissues that may be invaded by the tumor, continuously irradiating the tumor tissue, continuously killing tumor cells that fission at different stages and hypoxic cells around the tumor, while normal tissues are not damaged or only slightly damaged.

[0003] At present, iodine particles are implanted into patients using iodine particle implantation devices. Existing particle implantation devices include particle needles, particle cartridges, push rods, and particle guns. First, under the guidance of CT or ultrasound images, the particle needle is used to puncture the tumor to the predetermined position. According to the preoperative TPS plan, the push rod is used to push the particles in the particle cartridge to the appropriate position through the particle gun. After the particle needle is withdrawn to the next position and the push rod is withdrawn above the cartridge, the particle cartridge will automatically eject the particles. Repeat the above operation to implant the predetermined number of particles into the lesion according to the Paris principle.

[0004] In order to shield the radiation of iodine particles, the particle gun currently used is an integrated structure. During the operation, it is impossible to observe whether the iodine ions inside the particle cartridge enter the interior of the particle gun, and therefore it is impossible to determine how many iodine ions are implanted into the patient's body.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] Example 1

[0030] like Figure 1-3An iodine particle implanter shown includes a handle, a gun body and a storage container; one end of the gun body is fixedly connected to the handle, and the other end is provided with a mounting slot; the mounting slot is detachably connected to the storage container, and an implantation gun head is fixedly connected to one side of the gun body; an implantation passage is provided inside the implantation gun head; the implantation passage runs through the gun body; a push rod is provided on the side of the gun body away from the implantation gun head; one end of the push rod is inserted into the implantation passage; the implantation passage is connected to the mounting slot, and the bottom of the storage container is inserted into the implantation passage, so that the iodine particles placed in the storage container can enter the implantation passage. A magnifying lens is provided on the side wall of the gun body; the magnifying lens is aligned with the connection between the implantation passage and the mounting slot.

[0031] Specifically, the magnifying lens is a convex lens or a Fresnel lens.

[0032] During the process of implanting iodine particles, the number of iodine particles entering the implantation pathway, that is, the number of iodine particles entering the patient's body through the implantation pathway under the current circumstances, can be observed through a magnifying lens, which facilitates the control of the number of iodine particles implanted in the patient's body and facilitates the smooth progress of the operation.

[0033] Specifically, one end of the handle is fixedly connected to the gun body, and the other end is provided with a holding ring.

[0034] Furthermore, a transparent block is provided inside the gun body; the transparent block covers the connection between the implantation passage and the mounting groove. The function of the transparent block is that the side of the transparent block away from the magnifying lens is in contact with the implantation passage and the mounting groove at the same time, so that the connection between the implantation passage and the mounting groove can be observed through the transparent block.

[0035] like Figure 1-3 As shown, an expansion structure is provided at one end of the push rod away from the gun body. When in use, pushing the expansion structure can drive the push rod to move toward the gun body, thereby pushing part of the iodine particles in the reservoir along the implantation passage and finally into the patient's body. While reducing the pressure of the push rod on the doctor's hand, the expansion structure can also prevent the push rod from completely entering the implantation passage, preventing the push rod from passing through the implantation passage and stabbing the patient's body tissue.

[0036] Furthermore, one end of the implantation gun tip away from the gun body gradually shrinks to facilitate placement of the implantation gun tip into the patient's body.

[0037] During the operation, since the reservoir is in an inverted state, the iodine particles inside the reservoir will fall under the force of gravity and enter the implantation channel. The number of iodine particles is counted through a magnifying lens. When the number of iodine particles meets the surgical requirements, a push rod is used to push the iodine particles inside the implantation channel into the patient's body. During this process, the side wall of the push rod blocks the opening of the reservoir, preventing the remaining iodine particles inside the reservoir from continuing to enter the implantation channel.

[0038] Example 2

[0039] like Figure 4-5 The iodine seed implanter shown in the embodiment is different from that in embodiment 1 in that:

[0040] A protective cover is provided on the side wall of the gun body; the protective cover covers the side of the magnifying lens away from the implantation passage. During the operation, the protective cover can be opened to expose the magnifying lens, so that the connection between the implantation passage and the mounting groove can be clearly observed through the magnifying lens, and the number of iodine particles entering the implantation passage can be calculated. After the iodine particles are counted, the protective cover is used to cover the magnifying lens to block the radiation of the iodine particles and reduce the harm of the iodine particles to medical staff.

[0041] After the operation, the magnifying lens should be sealed with a protective cover to effectively prevent accidental scratches on the magnifying lens and extend the service life of the instrument.

[0042] Specifically, one end of the protective cover is hinged to the gun body, and the other end is detachably connected to the gun body. When the protective cover is opened, the protective cover does not completely separate from the gun body, so as to timely cover the magnifying lens and prevent the protective cover from being lost.

[0043] Example 3

[0044] like Figure 6 The iodine particle implanter shown in the figure is different from the embodiments 1 and 2 in that:

[0045] The outside of the push rod is wrapped with a resetter; one end of the resetter abuts against the expansion structure, and the other end abuts against the side wall of the gun body. The function of the resetter is that when it is observed that the number of iodine particles in the current implantation channel is insufficient, the pressure on the push rod is gradually relaxed, and the reset structure drives the push rod to move away from the implantation gun head, so that the push rod is away from the reservoir, and then the remaining iodine particles in the reservoir can continue to enter the implantation channel. The number of iodine particles in the implantation channel is calculated again. When the number of iodine particles meets the surgical requirements, the push rod is pushed again to push the iodine particles in the implantation channel into the patient's body.

[0046] Furthermore, a guide tube is fixedly connected to the side of the gun body away from the implantation gun head; the implantation passage runs through the guide tube; the push rod passes through the guide tube through the implantation passage. The guide tube is used to limit the moving direction of the push rod.

[0047] The above is only a specific implementation of the present application. Under the above teachings of the present application, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present application, and the protection scope of the present application shall be based on the protection scope of the claims.
