[0002] Before performing a cranial dissection, the cranial specimen needs to be perfused. The perfusion method mainly involves injecting silicone into the cerebral blood vessels to simulate the morphology of the brain blood vessels.

[0004] However, in actual operation, due to the high density of silicone, it is difficult to push silicone into the blood vessels, which is time-consuming and laborious. It is difficult for the user to apply force to push the syringe, making it difficult to achieve the purpose of uniform perfusion, resulting in the perfusion process being relatively laborious and slow. In addition, it is easy to shake during the pushing process, causing the silicone to leak out. Similarly, it is also relatively laborious to extract the silicone into the syringe.
[0005] At the same time, during the perfusion process, the difficulty in applying force leads to uneven perfusion speed, which easily increases the generation of bubbles during the perfusion process, thereby causing holes on the specimen surface and affecting the quality of specimen production.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] like Figure 1As shown, the utility model provides a booster and a silicone thruster having the same, including a thruster body 10, on which a syringe 20 is movably mounted, and a thrust assembly 30 is movably mounted at one end of the thruster body 10, the thrust assembly 30 rotates around its connection with the thruster body 10 and pushes the syringe 20 to be movably retracted and extended in a horizontal direction to form a booster thrust structure, and a limit assembly 40 is movably arranged on the thrust assembly 30, and after the limit assembly 40 rotates around its connection with the thrust assembly 30, it movably abuts against the handle end of the syringe 20 to be fixed to form a reciprocating push-pull structure.
[0030] The utility model adopts a movable connection to form a silicone injection thruster with a power-assisted propulsion structure. By converting rotation into a sliding propulsion method, it is beneficial to push the syringe to slowly and evenly inject silicone. The limiting structure facilitates the fixing of the syringe, and can drive the syringe to repeatedly extract and inject in the thruster, which is convenient for more labor-saving extraction and injection of silicone, making the injection process more stable and uniform, thereby reducing the generation of bubbles and facilitating improved production quality.
[0031] The pusher body 10 is used to drive the syringe 20 for infusion, and the pulling structure can be converted by rotation. The rotation method is more labor-saving, which is conducive to pushing the silicone with higher density for infusion, making the silicone infusion more uniform. At the same time, the limit assembly 40 is used to fix the handle end of the syringe 20, so that the silicone raw material can be extracted into the syringe 20 for the next infusion without taking out the syringe 20, which is convenient for repeated extraction and infusion.
[0032] like Figure 1 and Figure 2 As shown, the propulsion assembly 30 includes a transmission shaft 31, and threads are provided on the outer wall of the transmission shaft 31 and the inner wall of the propeller body 10. One end of the transmission shaft 31 is rotatably connected to a propulsion block 32, and a rocker 33 is fixedly installed on the side of the transmission shaft 31 away from the propulsion block 32. The transmission shaft 31 is threadedly connected to the propeller body 10 and drives the propulsion block 32 to move horizontally;
[0033] The diameter of the propulsion block 32 is smaller than the diameter of the transmission shaft 31 , and a movable groove 34 is provided on the transmission shaft 31 .
[0034] The transmission shaft 31 is threadedly connected to the propeller body 10, and the rocker 33 is rotated to drive the transmission shaft 31 to move spirally in the propeller body 10. At the same time, the transmission shaft 31 is rotationally connected to the propulsion block 32, driving the propulsion block 32 to translate, so that one side of the propulsion block 32 pushes the syringe 20 to inject silicone. The push of the syringe 20 is more stable and uniform through the rotation of the thread, and the purpose of saving effort is achieved, which is conducive to reducing the generation of bubbles.
[0035] like Figure 2 and Figure 3 As shown, the limit assembly 40 includes a lever 41 movably inserted into the movable groove 34, the outer wall of the lever 41 is located on the inner wall of the movable groove 34 and is provided with a protrusion, a spring is fixedly installed at the connection position between the protrusion and the movable groove 34, one end of the lever 41 passes through the inner wall of the movable groove 34 and the inner wall of the thrust block 32 and extends to one side of the thrust block 32, and a limit block 42 is fixedly installed at one end of the lever 41 close to the thrust block 32.
[0036] By rotating the lever 41 180 degrees to the other side, a torque is generated on the spring on the lever 41, driving the limit block 42 to rotate until it is in active contact with the pusher body 10. At this time, the syringe 20 is placed in the pusher body 10, so that the handle end of the syringe 20 is in active contact with the pusher block 32.
[0037] Rotate the lever 41 in the opposite direction, and the limit block 42 is driven to return to the initial position through the elastic recovery of the spring, so that the limit block 42 is located on the side of the handle end of the syringe 20 to limit and fix the handle end of the syringe 20, thereby facilitating the fixation of the handle end of the syringe 20 and the propulsion assembly 30, and facilitating the syringe 20 to complete the propulsion and extraction actions through the propulsion assembly 30, and facilitating the extraction and re-injection of silicone after the injection of silicone into the syringe 20 is completed, and can perform repeated extraction and injection operations without taking out the syringe 20 for operation.
[0038] like Figure 2 and Figure 3 As shown, a piston handle 21 is movably provided at one end of the syringe 20, and the lever 41 rotates around the connection between the lever 41 and the propulsion assembly 30 to drive the limit block 42 to rotate and then movably abut against the piston handle 21 to form a limit structure;
[0039] A groove is provided on one side of the limit block 42 , and a movable rod 41 is movably installed in the limit block 42 in the groove. An arc block 422 is fixedly installed at one end of the movable rod 41 , and a spring is fixedly installed at the connection position between the movable rod 41 and the limit block 42 .
[0040] The limit block 42 is rotated to one side of the piston handle 21 to limit and fix it, and at the same time, the movable rod 41 slides outward and extends through the spring at one end thereof, which is beneficial to expand the use length of the limit block 42 and better limit and fix the piston handle 21.
[0041] When the syringe 20 is disassembled, the limit block 42 is rotated to the other side, driving the arc block 422 to flexibly abut against the thruster body 10 and push the movable rod 41 to retract into the limit block 42, so that the limit block 42 and the piston handle 21 are separated from each other, which facilitates the removal of the syringe 20. At the same time, the thrust applied to the movable rod 41 and the arc block 422 by the spring is conducive to limiting and fixing the limit block 42, thereby facilitating the disassembly and assembly of the syringe 20.
[0042] like Figure 1 and Figure 2 As shown, a clamping assembly 50 is symmetrically arranged at the opening of the pusher body 10 with the syringe 20 as the center, and the clamping assembly 50 includes a limit rod 51 movably arranged on the pusher body 10, a clamping block 52 is movably arranged on one side of the limit rod 51, and a push rod 53 is slidably connected to one end of the pusher body 10;
[0043] Among them, a spring is fixedly installed at the connection between the limit rod 51 and the thruster body 10 above the push rod 53, a groove matching the block 52 is opened on the limit rod 51, and a spring is arranged at the connection between the block 52 and the groove, and the block 52 and the push rod 53 are on the same horizontal line.
[0044] Insert the syringe 20 from the opening of the pusher body 10 for installation. After pushing the syringe 20 into the appropriate position, press the limit rod 51 downward, and at the same time stretch the spring on the limit rod 51. At this time, the clamping block 52 is recovered in the groove of the limit rod 51, and at the same time, the spring on the clamping block 52 is squeezed. When the limit rod 51 is pressed to the appropriate position, the clamping block 52 is elastically acted upon by the spring and is clamped with the pusher body 10. One side of the clamping block 52 pushes the push rod 53 to slide outward for a certain distance. At this time, the bottom end of the limit rod 51 is pressed down to the appropriate position and abuts against the outer wall of the syringe 20.
[0045] The bottom end of the limiting rod 51 is a concave structure, and the concave portion of the bottom end of the limiting rod 51 is clamped and fixed to the external protruding portion of the syringe 20, so that the syringe 20 is fixed in the pusher body 10, thereby preventing the syringe 20 from shaking and shifting during the pushing and withdrawal process.
[0046] During disassembly, the push rod 53 is pressed to push the block 52 back into the groove of the limiting rod 51. The limiting rod 51 is driven to rebound and rise by the elastic action of the spring on the limiting rod 51, so that the bottom end of the limiting rod 51 rises to a certain height, thereby canceling the limit on the syringe 20, making it convenient to remove the syringe 20 from the opening of the thruster body 10, and facilitating the installation and disassembly of the syringe 20.
[0047] The semi-open setting facilitates the assembly of the syringe 20. At the same time, during use, it is easy to observe the internal capacity and usage status of the syringe 20, reducing the obstruction of the injection end of the syringe 20 and facilitating use.
[0048] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
