Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an automatic filling device for a particle implantation gun magazine. Background Technology

[0002] Minimally invasive interventional nuclear medicine (nuclear-nuclide intervention / interventional nuclear medicine) is an interdisciplinary field that integrates the precise targeting of nuclear medicine with minimally invasive interventional procedures. It uses image guidance to precisely deliver radiopharmaceuticals / nucleotides to lesions, achieving local internal irradiation, targeted therapy, and functional diagnosis. It is the third major diagnostic and treatment method after internal medicine and surgery.

[0003] Particle implantation guns are used in minimally invasive interventional procedures in nuclear medicine to implant particles... 125 I, 103 Specialized instruments for precisely, orderly, and quantitatively delivering radioactive particles such as Pd into tumor tissue. Their core working principle relies on the instrument's structure and image guidance to deliver pre-loaded radioactive particles one by one to the designated location of the lesion according to the source placement requirements of the preoperative treatment planning system (TPS). This achieves continuous low-dose internal irradiation therapy for the tumor. Essentially, it is a synergistic effect of "precise delivery + quantitative control". The entire process must be completed under the guidance of images such as CT and ultrasound to ensure that the particle source placement meets the treatment guidelines.

[0004] Most existing particle loading methods rely on doctors wearing lead gloves and using tweezers to pick up particles and load them into magazines. This method has the following problems: (1) Low operational efficiency, as only one particle can be picked up at a time, and it takes a long time to load a full magazine; (2) High operational risk, as doctors need to be in close contact with radioactive particles, and even with lead gloves, there is still a risk of radiation exposure during long-term operation; (3) Operational accuracy depends on human experience, and the arrangement and order of particles are prone to deviation; (4) High labor intensity, as preparation work is time-consuming and labor-intensive for surgeries that require a large number of particles to be implanted.

[0005] For example, Chinese invention patent CN105413049B discloses a radioactive particle implantation gun, including a gun body mounted on a handle. The gun body has an adapter assembly at its front end and a pusher assembly at its rear end. The gun body contains a cavity for fixing a magazine assembly. One side wall of the gun body has two holes, both penetrating the gun body. A positioning pin is located in the hole near the top of the gun body, and a positioning pin cover is located in the hole near the bottom of the gun body. The advantages of this invention are: by integrating the adapter assembly, gun body, and pusher assembly into one unit, it overcomes the problem in existing technologies where the pusher needs to be aligned every time it is pushed in for insertion and removal, allowing the operator to concentrate and improving the compatibility of the device; since each component of the implantation gun is independent, when a component is damaged, only the damaged part needs to be replaced, overcoming the problem of the entire implantation device being scrapped in existing technologies; the structure is simple, the operation is convenient, and it is easy to carry.

[0006] Analysis of the invention and existing technology revealed that while the invention improved the compatibility and maintainability of the implant gun, it did not solve the problem of low particle loading efficiency, and particle loading still required manual operation.

[0007] Therefore, there is an urgent need for a device that can automatically, efficiently, and safely complete particle loading to reduce the workload of doctors, improve operational efficiency, and reduce the risk of radiation exposure. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention proposes an automatic filling device for particle implantation gun magazines, which solves the technical problems mentioned in the background art, namely, that the existing particle filling process relies on doctors wearing lead gloves and using tweezers to pick up particles and fill them into the magazine, which is not efficient enough and poses a risk of radiation exposure.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an automatic filling device for particle-implanted bullet magazines, comprising: The main body includes a particle chamber and a discharge chute; A lifting assembly is installed inside the particle chamber, which can transport disordered particles in the particle chamber to one end of the discharge hopper feed inlet. A drive component is arranged on the main body and connected to the lifting component to drive the lifting component to perform lifting and lowering movements; A filling linkage mechanism, mounted on the main body and connected to the drive assembly, is located at one end of the discharge hopper outlet; and A quick-release magazine assembly is located on one side of the filling linkage mechanism to install the magazine to be filled.

[0010] Furthermore, the lifting assembly includes: Multiple partitions of varying heights are provided and fixedly installed in the particle chamber from low to high. The spacing between the multiple partitions should be greater than the diameter of the particles. A lifting component is slidably installed within a square space formed by the multiple partitions and the particle chamber, and the lifting component has multiple top blocks arranged from low to high; and A sliding groove is provided on the side of the lifting member near the drive assembly.

[0011] Furthermore, the top of the partition is provided with a first inclined surface, which is inclined toward the side of the magazine quick-release assembly.

[0012] Furthermore, the top of the lifting member is provided with a second inclined surface, which is inclined toward the side of the magazine quick-release assembly.

[0013] Furthermore, the driving component includes: The main shaft is rotatably mounted on the main body; A turntable is fixedly arranged at one end of the main shaft, and a slide bar is provided on the turntable, the slide bar being able to slide within the slide groove; and The grip shaft is located at the end of the main shaft away from the turntable and is not on the same axis as the main shaft.

[0014] Furthermore, the filling linkage mechanism includes: The first link is hinged to the grip shaft; The second connecting rod has one end hinged to the main body and the other end hinged to the middle of the first connecting rod; and A push rod is located at the end of the first connecting rod away from the grip shaft.

[0015] Furthermore, the main body is also provided with an L-shaped receiving component, and the L-shaped receiving component is provided with... The side baffle allows the particles to stop moving on the L-shaped receiving member after they roll out of the discharge hopper.

[0016] Furthermore, the quick-release magazine assembly includes: A filler, fixedly disposed on one side of the L-shaped receiving member, includes a connecting section and a joint section. The particles, driven by the filling linkage mechanism, enter the connecting section and slide into the magazine on the joint section. Magnets, at least two in number, are arranged on the side of the connector section facing the magazine.

[0017] Furthermore, the magazine has multiple grooves that can hold the magnet in place.

[0018] Furthermore, the groove is made of a magnetic material.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention achieves automated and orderly filling of radioactive particles through the synergistic action of a lifting component, a driving component, and a filling linkage mechanism. The lifting component employs a multi-stage partition and lifting element design, enabling the orderly, step-by-step transport of randomly stacked radioactive particles within the particle chamber to the discharge hopper, avoiding particle jamming and overlap during transport. The driving component, through the cooperation of a turntable and a slide bar, converts rotational motion into linear lifting motion of the lifting element, achieving a continuous and stable particle supply. The filling linkage mechanism utilizes the linkage transmission principle to transmit the motion of the driving component to the particle pushing end, achieving precise particle delivery. The entire filling process requires no manual intervention, allowing for the continuous filling of multiple particles at once. Compared to traditional manual tweezers, this significantly improves filling efficiency and greatly reduces preoperative preparation time.

[0020] 2. This invention achieves fully automated particle filling. Doctors do not need to be in close contact with radioactive particles; they only need to install the clip on the quick-release clip assembly and operate the drive assembly to complete the filling. The quick-release clip assembly adopts a magnetic adsorption quick-release design. Corresponding positions on the clip are provided with grooves made of magnetic material. The magnetic adsorption between the magnet and the grooves enables rapid installation and positioning of the clip, making operation simple and accurate. The L-shaped receiving part and side baffle design ensure that the particles accurately stop at the predetermined position after rolling out of the discharge hopper, avoiding the risk of radiation contamination caused by particle falling or misoperation. Furthermore, the enclosed structure design between the various components of the device effectively blocks radiation leakage, providing reliable radiation protection for the operator.

[0021] 3. The lifting assembly of this invention features a first inclined surface at the top of the partition plate and a second inclined surface at the top of the lifting component, both inclined towards the side of the quick-release magazine assembly. This inclined surface design allows particles to automatically roll to one side under their own gravity during the lifting process. Combined with the graded height design of the partition plate, it achieves the step-by-step separation and orderly arrangement of particles. The interval between the partition plates is greater than the particle diameter but less than the sum of the diameters of two particles, ensuring that only one particle can pass through at a time, effectively preventing particle overlap and jamming. The handle shaft and main shaft of the drive assembly are eccentrically set. Through the cooperation of the turntable, slide bar, and slide groove, the rotational motion is converted into the reciprocating linear motion of the lifting component. The motion conversion is smooth and reliable, with low noise and minimal wear. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0026] Example: like Figures 1 to 8 As shown, this invention provides an automatic filling device for particle-implanted magazines, mainly used for filling radioactive particles (such as...) 125 I, 103Pd particles (such as Pd particles) are automatically and systematically filled into the magazine of the particle implantation gun. The device mainly consists of five parts: the main body 101, the lifting assembly, the drive assembly, the filling linkage mechanism, and the magazine quick-release assembly.

[0027] The main body 101 serves as the support and installation foundation for the entire device, and mainly consists of two parts: the particle chamber 102 and the discharge hopper 103. The particle chamber 102 stores the radioactive particles to be filled. The discharge hopper 103 is connected to one side of the particle chamber 102 and is arranged at an angle downwards, with its lower end forming a discharge port for discharging the particles one by one to the subsequent filling station. The inclination angle of the discharge hopper 103 is determined according to the size and material of the particles, and is generally set between 15° and 30° to ensure that the particles can roll smoothly down under gravity.

[0028] The lifting assembly is located inside the particle chamber 102 and is the core component for realizing automatic particle transport. The lifting assembly mainly consists of a partition 201, a lifting element 202, and a chute 210.

[0029] Multiple partitions 201 are provided, the specific number of which can be determined according to the height of the particle chamber 102 and the particle size, generally set to 3-6. The heights of the multiple partitions 201 vary, increasing sequentially from bottom to top, forming a stepped distribution within the particle chamber 102. The partitions 201 are fixedly connected to the side walls of the particle chamber 102, and the connection method can be welding, bolting, or integral molding. The vertical spacing between two adjacent partitions 201 is designed to be greater than the diameter of a single radioactive particle, but less than the sum of the diameters of the two particles. This ensures that only one particle can pass through the gap between the partitions 201 at a time, preventing particles from overlapping.

[0030] The top of the partition 201 is provided with a first inclined surface 204, which is inclined toward the side of the quick-release magazine assembly, and the inclination angle is generally 10°-20°. This inclined surface design has two functions: first, to guide the particles to roll to one side, making it easier for them to enter the top block 203 of the lifting component 202; second, to reduce the frictional resistance between the particles and the partition 201, so that the particles can slide down smoothly.

[0031] The lifting component 202 is a long, strip-shaped plate structure that is slidably installed within a square space formed by multiple partitions 201 and the sidewalls of the particle chamber 102. Multiple top blocks 203 are arranged from low to high along the height direction of the lifting component 202, with the number of top blocks 203 corresponding to the number of partitions 201. Each top block 203 is positioned to match a partition 201. The size of each top block 203 is designed to lift one particle, with its top surface width slightly smaller than the particle's diameter, ensuring that only one particle can be lifted at a time. Driven by the drive assembly, the lifting component 202 can reciprocate up and down within the slide 210. When the lifting component 202 moves upward, the top block 203 lifts the particle over the corresponding partition 201, transferring the particle to a higher-level partition 201; when the lifting component 202 moves downward, the top block 203 passes under the partition 201, preparing for the next lifting action.

[0032] The top of the lifting component 202 is also provided with a second inclined surface 205, which is inclined towards the discharge hopper side, and the inclination angle is adapted to the first inclined surface 204. The function of the second inclined surface 205 is to guide the particles on the top block 203 to roll to one side when the lifting component 202 rises to the highest position, so that they can smoothly enter the discharge hopper 103.

[0033] A slide groove 210 is disposed on the side of the lifting member 202 near the drive assembly. The slide groove 210 is an elongated groove extending horizontally along the lifting member 202. The cross-sectional shape of the slide groove 210 can be determined according to the shape of the slider 208 of the drive assembly, and is generally rectangular or arc-shaped. The length of the slide groove 210 must meet the stroke requirements of the lifting member 202 to ensure that the slider 208 will not come out during its full sliding motion within the slide groove 210.

[0034] The drive assembly is mounted on the main body 101 and provides power to the lifting assembly and filling linkage mechanism. The drive assembly mainly consists of a main shaft 206, a turntable 207, and a handle shaft 209.

[0035] The main shaft 206 is rotatably mounted on the main body 101, and the axial direction of the main shaft 206 is perpendicular to the sliding direction of the lifting member 202. The main shaft 206 is supported in a bearing housing of the main body 101 by bearings, and the bearing housing may be a sealed bearing design to prevent particle dust from entering the bearing. One end of the main shaft 206 extends to the outside of the main body 101 for connecting a drive source (such as a hand crank or motor).

[0036] A turntable 207 is fixedly arranged at one end of the main shaft 206 located inside the main body 101, and rotates synchronously with the main shaft 206. A slide bar 208 is fixedly arranged radially on the turntable 207. The axis of the slide bar 208 is parallel to the axis of the main shaft 206, and the connection position between the slide bar 208 and the turntable 207 is offset from the rotation center of the turntable 207. The diameter of the slide bar 208 matches the slide groove 210 on the lifting member 202, and one end of the slide bar 208 is inserted into the slide groove 210 and can slide within the slide groove 210. When the turntable 207 rotates, the slide bar 208 performs a circular motion, which drives the lifting member 202 to perform a reciprocating up-and-down motion through the slide groove 210, thereby realizing the lifting action.

[0037] The grip shaft 209 is located at the end of the main shaft 206 furthest from the turntable 207 and is not coaxial with the main shaft 206; that is, the grip shaft 209 and the main shaft 206 are eccentrically positioned. The grip shaft 209 is used to connect to the drive handle. The operator grips and rotates the drive handle, causing the main shaft 206 and the turntable 207 to rotate. The eccentric design of the grip shaft 209 increases the rotation radius, making operation more effortless. The drive handle can be equipped with anti-slip textures or a rubber sleeve to improve grip comfort.

[0038] The filling linkage mechanism is mounted on the main body 101 and connected to the drive assembly. It is located at one end of the discharge port of the discharge hopper 103 and is used to push the particles discharged from the discharge hopper 103 into the magazine of the magazine quick-release assembly. The filling linkage mechanism mainly consists of a first link 301, a second link 302, and a push rod 303.

[0039] One end of the first link 301 is hinged to the handle shaft 209, with the hinge point located at the end of the handle shaft 209. The first link 301 can rotate around the handle shaft 209, and when the handle shaft 209 rotates with the main shaft 206, the first link 301 is driven to swing.

[0040] One end of the second link 302 is hinged to the main body 101, and the hinge point is fixed to the support of the main body 101; the other end is hinged to the middle of the first link 301. The second link 302 serves to limit movement and provide support, restricting the movement trajectory of the push rod 303.

[0041] A push rod 303 is positioned at the end of the first link 301 furthest from the grip shaft 209, and the axis of the push rod 303 is perpendicular to the filling direction of the magazine. The diameter of the push rod 303 is slightly smaller than the diameter of the radioactive particles to ensure accurate particle pushing. When the first link 301 swings under the drive of the grip shaft 209, the push rod 303 reciprocates under the constraint of the second link 302 (linear push, arc return), pushing the particles into the magazine when moving forward and resetting when moving backward to prepare for the next push.

[0042] The filling linkage mechanism adopts the design principle of a four-bar linkage, converting the rotational motion of the drive component into the reciprocating motion of the push rod 303, ensuring smooth and reliable motion conversion. By rationally designing the length ratio of each link, the stroke and speed of the push rod 303 can be precisely controlled, ensuring that only one particle is pushed at a time, and that the pushing force is moderate, which can reliably push the particle without damaging the particle or the magazine.

[0043] The main body 101 is also provided with an L-shaped receiving part 304, which is located below the discharge port of the discharge hopper 103 and is used to receive the particles rolling out from the discharge hopper 103. The L-shaped receiving part 304 is L-shaped and is also provided with a side baffle 305, which is located on one side of the horizontal receiving surface and is used to prevent particles from sliding off the side.

[0044] After the particles roll out of the discharge hopper 103, they land on the horizontal receiving surface of the L-shaped receiving member 304 and are eventually stopped by the vertical baffle. At this point, the particle's position is aligned with the inlet of the filling member 306 of the magazine quick-release assembly, awaiting to be pushed into the magazine by the push rod 303. The design of the L-shaped receiving member 304 and the side baffle 305 ensures the accuracy and consistency of the particle's position, providing a reliable guarantee for the subsequent filling operation.

[0045] The quick-release magazine assembly is located on one side of the filling linkage mechanism and is used to install the magazine 104 to be filled. The quick-release magazine assembly mainly consists of a filling element 306 and a magnet 309.

[0046] The filler 306 is fixedly disposed on one side of the L-shaped receiver 304 and includes a connecting section 307 and a connector section 308. The connecting section 307 is a hollow square tube structure with an inner diameter slightly larger than the diameter of the radioactive particle, and the axis of the particle is aligned with the axis of the connecting section 307. The connector section 308 is located at one end of the connecting section 307 and is used to mate with the magazine 104. The shape and size of the connector section 308 match the inlet of the magazine 104, ensuring that the particle can smoothly slide from the connecting section 307 into the magazine 104.

[0047] At least two magnets 309 are provided, both located on the side of the connector section 308 facing the magazine 104. The magnets 309 are made of strong permanent magnet material (such as neodymium iron boron magnets) and fix the magazine 104 by magnetic attraction. The position and number of magnets 309 are determined according to the size and weight of the magazine 104, generally 2-4 are symmetrically arranged to ensure the magazine 104 is securely and reliably fixed.

[0048] The magazine 104 has multiple grooves 310, the positions of which correspond to the positions of the magnets 309. When the magazine 104 is installed on the connector section 308, the magnets 309 engage with the grooves 310, securing the magazine 104 firmly through magnetic force. The grooves 310 are made of magnetic materials, such as iron, nickel, cobalt, or other magnetic metals, or have embedded magnetic material sheets, which enhances the attraction force with the magnets 309 and improves the reliability of the fixation.

[0049] The magazine quick-release assembly features a magnetic quick-release design, making the installation and removal of the magazine 104 extremely convenient. During installation, simply align the magazine 104 with the connector section 308 and bring it close; the magnet 309 will automatically attract the magazine 104 and lock it into the correct position. During removal, simply overcome the magnetic force to pull the magazine 104 out. This design avoids the cumbersome operations of traditional threaded or snap-fit ​​connections, greatly improving work efficiency.

[0050] In this embodiment, the drive component is driven manually. In an alternative embodiment, a motor drive can also be used, in which case one end of the spindle 206 is connected to a motor (such as a stepper motor or a servo motor), and the rotation angle and speed of the motor are controlled by an electronic control system to achieve automated operation.

[0051] Specific usage and beneficial effects of the present invention: The doctor pours the radioactive particles to be filled into the particle chamber 102 in batches and closes the chamber lid. The particles naturally accumulate at the bottom of the particle chamber 102 under gravity. The operator turns the drive handle, which drives the main shaft 206 and the turntable 207 to rotate via the handle shaft 209. As the turntable 207 rotates, the slide bar 208 moves in a circular motion driven by the turntable 207, while simultaneously sliding along the groove 210 on the lifting component 202. The movement of the slide bar 208 causes the lifting component 202 to move up and down reciprocally.

[0052] As the lifting component 202 moves upward, the bottommost block 203 lifts the particle over the bottommost partition 201 and transfers it to the second partition 201. Due to the guiding effect of the first inclined surface 204 at the top of the partition 201 and the second inclined surface 205 at the top of the lifting component 202, the particle automatically rolls to one side after passing the partition 201 and enters the next lifting position.

[0053] The lifting component 202 continues to rise, and the top block 203 of the second layer lifts the particles of the second layer over the second layer partition 201, transporting them to the third layer partition 201. This cycle repeats, with particles being transported upwards level by level, eventually reaching the highest layer partition 201.

[0054] When the lifting component 202 rises to its highest position, the top block 203 at the highest level lifts the particles to a height exceeding the feed inlet height of the discharge hopper 103, and the particles roll into the discharge hopper 103 under the guidance of the second inclined surface 205.

[0055] Particles entering the discharge hopper 103 roll down the hopper under the action of gravity, and finally roll out from the lower discharge port of the discharge hopper 103, land on the L-shaped receiving part 304, and are finally stopped at the predetermined position by the vertical baffle.

[0056] While the lifting component 202 is conveying particles upwards, the rotation of the handle shaft 209 also drives the push rod 303 to reciprocate through the first link 301 and the second link 302. When the particles stop on the L-shaped receiving component 304, the push rod 303 is in the forward-propelling position, pushing the particles from the L-shaped receiving component 304 into the connecting section 307 of the filling component 306, and then continuing to push, so that the particles pass through the connecting section 307 and enter the magazine 104 on the connector section 308.

[0057] The entire filling process requires no manual intervention; from particle transfer to the filling magazine, everything is completed automatically, greatly improving operational efficiency. Through the multi-stage partitions and lifting components of the lifting assembly, the particles are separated step by step and supplied in an orderly manner, effectively preventing particle jamming and overlap.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
