Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a bone implant. Background Art

[0002] Endoscopic lumbar surgery is a minimally invasive surgical technique that uses endoscopic equipment to treat lumbar degenerative diseases such as lumbar disc herniation and lumbar spinal stenosis. During the operation, the doctor needs to build a dam environment and perform bone grafting on the lumbar spine in the dam environment. The reason for building the dam is that the surgical field can be clearer in an underwater environment. If there is no water medium, there will be all kinds of blood, and the operation cavity cannot be formed. In the actual operation process at this stage, doctors generally use a bone grafting funnel to push the broken bones into the intervertebral space, but the bone grafting funnel can only guide the broken bones. Bone grafting in a water environment The broken bones at the end of the funnel are easily washed away by the water flow. In order to solve this problem, the doctor will choose to cut off the needle end of the 1ml syringe, then put the bone into the cut 1ml syringe barrel, and finally use the piston of the syringe to push the broken bones into the intervertebral space. Although this bone grafting method can slow down the speed at which the broken bones are washed away by water, each operation needs to destroy a 1ml syringe, which increases medical costs. In addition, the efficiency is low in the process of loading the broken bones into the 1ml syringe, which delays the progress of the operation. Therefore, the present invention provides a bone grafting device to meet the needs. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a bone grafting device which, by providing an implanting component, can prevent the bone fragments from being washed away by water during implantation due to the presence of water medium when the bone grafting device is used in a water environment. Moreover, the implanting component can greatly improve the efficiency of bone grafting and the comfort level for doctors when using the bone grafting device during actual operation, thereby greatly reducing the operating burden of doctors during the entire bone grafting process. The above arrangement can solve the problem that the bone fragments are easily washed away by water when the bone grafting device is used in a water environment.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] Optionally, a first baffle and a second baffle are fixedly connected to the inner wall of the handle, an arc-shaped portion is fixedly connected to one end of the bottom of the second baffle, and an arc-shaped groove consistent with the contour of the arc-shaped portion is formed on the top of the piston.

[0008] Optionally, one side of the skateboard is fixedly connected to a slider, one side of the slider is fixedly connected to a connecting block, the skateboard, the slider and the connecting block are an integrated structure connected together in sequence, and the skateboard and the push rod are fixedly connected through the slider and the connecting block.

[0009] Optionally, a lightweight groove is provided on the support plate, and two rubber slides are fixedly connected to the inner circumference of the support plate, and the rubber slides are curved sheet structures made of rubber material.

[0010] Optionally, an expansion plate is fixedly connected to one end of the bottom of the extrusion plate, a conical cylinder is fixedly connected to one end of the top of the extrusion plate, and a segmented groove is provided at the middle of the extrusion plate.

[0011] Optionally, the conical cylinder is a conical structure recessed toward the middle, a recessed portion is installed at the middle position of the extrusion plate, the recessed portion is an arc-shaped structure recessed toward the middle, side plates are fixedly connected on both sides of the expansion plate, and the thickness of the side plates is smaller than the thickness of the expansion plate.

[0012] Optionally, a stopper is fixedly connected to one end of the flip cover, a clamping block is fixedly connected to the bottom of the flip cover, and a first slot matching the shape of the clamping block is formed on the top of the handle.

[0013] Optionally, a plurality of insertion rods distributed in a circular array are fixedly connected to the top of the implant tube, a plug is fixedly connected to one end of the insertion rod, and a second slot matching the shape of the plug is formed at the bottom of the handle.

[0014] Optionally, a scale is provided on the outer wall of the implant tube, the middle of the plug is a hollow structure, and the handle and the implant tube are fixedly connected through the plug and the second slot.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, by setting up an implant component, when the bone grafter is used in a water environment, the bone fragments will not be washed away by water during the implantation process due to the presence of water medium. In addition, the implant component can greatly improve the efficiency of bone grafting and the comfort of the doctor using the bone grafter during actual operation, thereby greatly reducing the doctor's operating burden during the entire bone grafting process.

[0017] By setting the grip, the overall contour of the grip is a flat plate-like structure. When the doctor holds the grip with his hand, the finger fitting part on one side of the grip just fits with the doctor's four fingers except the thumb, the doctor's thumb fits with the thumb pressing part, and the doctor's palm just wraps around the outside of the palm fitting part. The above structure is more in line with the contour of human fingers in the gripping state, thereby making the doctor more comfortable in the process of holding the grip, with a better gripping effect, more conducive to the doctor's one-handed operation, and ensuring the doctor's stability during one-handed operation.

[0018] By arranging a slide plate in the implant component, the slide plate is installed on the thumb pressing part on one side of the handle, and the thumb pressing part has an inwardly concave arc. When the doctor holds the handle, the thumb contacts the outer wall of the thumb pressing part. This concave arc makes it easier for the thumb to push the slide plate, thereby saving the doctor more effort during the actual operation. Because the doctor generally performs bone grafting with one hand during the actual operation, the way the bone grafter of the present application is held and the setting of the thumb sliding up and down to push the piston can greatly reduce the doctor's operating burden and improve the efficiency of bone grafting.

[0019] By arranging a flap in the implant component, when the doctor holds the handle, the block is just above the doctor's thumb. The flap is thinned at the position where the flap and the handle are connected. The thinned flap is more easily deformed under the action of external force. When the doctor needs to open the flap, he only needs to push the block upward with his thumb. Under the action of the thrust, the block will disengage from the first slot and the flap will flip outward. The flap will deform and bend during the flipping process. At this time, the top of the handle is no longer blocked, and the doctor can add the broken bones from the top of the handle. The above structural setting makes it easier for the doctor to add broken bones inside the handle, thereby improving the efficiency of the entire bone grafting process.

[0020] By arranging the first baffle and the second baffle in the implant component, the guiding effect of the broken bones can be achieved under the blocking effect of the first baffle and the second baffle, and the broken bones falling from the top of the handle will fall into the implant tube under the guidance of the first baffle and the second baffle. Furthermore, the installation position of the first baffle is set to prevent the broken bones from being retained at the position of the finger fitting part, and the installation position of the second baffle is set to prevent the broken bones from leaking from the slide groove.

[0021] By arranging a piston in the implant component, the piston can cooperate with the second baffle plate. The effect achieved by the cooperation is that there are two states between the piston and the push rod: when the slide plate slides to the top of the handle, the piston rotates at the bottom of the push rod with the guidance of the arc portion and the arc groove. At this time, the piston is folded and stored on one side of the second baffle plate. In this state, the doctor can add crushed bones to the implant tube; when the slide plate slides downward and disengages from the limit of the second baffle plate, the piston rotates again under the action of its own gravity and is in a horizontal state. At this time, the piston continues to slide downward to push the crushed bones inside the implant tube out. The setting of these two states maximizes the use of the structural properties of the piston, making the addition of crushed bones to the implant tube efficient and without blockage.

[0022] By setting up a support plate, when the doctor inserts the implant tube into the surface of the support plate, the support plate presents a circular structure. During the actual operation, the doctor can allow the support plate to contact the patient's skin surface and use the support effect of the support plate on the implant tube to assist in positioning. The support of the support plate will not only reduce the burden on the doctor's handheld handle, but also make the implant tube more stable during the bone fragment implantation process and the implantation efficiency higher.

[0043] like Figures 1 to 11As shown, an embodiment of the present invention provides a bone implanter, comprising a handle 1, an implant tube 2 is inserted at the bottom of the handle 1, a flip cover 3 is fixedly connected to the top of the handle 1, a finger fitting portion 101 is installed on one side of the handle 1, an index finger limiting plate 104 is fixedly connected to one side of the top of the handle 1, a thumb pressing portion 102 and a palm fitting portion 103 are installed on the side of the handle 1 opposite to the finger fitting portion 101, a stopper 301 is fixedly connected to one end of the flip cover 3, a card block 302 is fixedly connected to the bottom of the flip cover 3, a first slot 105 matched with the shape of the card block 302 is provided on the top of the handle 1, a plurality of insertion rods 201 distributed in a circular array are fixedly connected to the top of the implant tube 2, a plug 202 is fixedly connected to one end of the insertion rod 201, a second slot 110 matched with the shape of the plug 202 is provided at the bottom of the handle 1, a scale is provided on the outer wall of the implant tube 2, the middle of the plug 202 is a hollow structure, and the handle 1 It is fixedly connected to the implant tube 2 through a plug 202 and a second slot 110. In the present application, a special bone implanter structure is provided to allow the doctor to more conveniently implant the broken bones into the intervertebral space of the patient. The bone implanter is divided into two parts: a handle 1 and an implant tube 2. The doctor needs to hold the handle 1 with his hand during the actual operation, and then insert the implant tube 2 into the patient's body. The overall contour of the handle 1 is a flat plate-like structure. When the doctor holds the handle 1 with his hand, the finger fitting portion 101 on one side of the handle 1 just fits with the doctor's four fingers except the thumb, and the doctor's thumb fits with the thumb pressing portion 102, and the doctor's palm just wraps around the outside of the palm fitting portion 103. The above structure is more in line with the contour of the human fingers in the gripping state, thereby making the doctor more comfortable in the process of holding the handle 1, with a better gripping effect, more conducive to the doctor's one-handed operation, and ensuring the stability of the doctor during the one-handed operation.

[0044] The interior of the handle 1 is a hollow structure, so that the doctor can add crushed bones into the handle 1. Specifically, the top of the handle 1 is capped by the flip cover 3. The flip cover 3 is a soft sheet structure, and one end of the flip cover 3 is fixed to the top of the handle 1, and a stopper 301 is installed at the other end of the flip cover 3. When the doctor holds the handle 1, the stopper 301 is just above the doctor's thumb. The flip cover 3 is thinned at the position where the flip cover 3 and the handle 1 are connected. The thinned flip cover 3 is more likely to be deformed under the action of external force. When the doctor needs to open the flip cover 3, he only needs to push the stopper 301 upward with his thumb. Under the action of the thrust, the block 302 will disengage from the first slot 105, and the flip cover 3 will also flip outward. During the flipping process, the flip cover 3 will be deformed and bent, and the top of the handle 1 will no longer The doctor can add the broken bones from the top of the handle 1. When the broken bones are added, the doctor stops applying force to the flip cover 3, and the flip cover 3 can be reset by means of the characteristics of its own structure. After resetting, the doctor manually presses the card block 302 to allow the card block 302 to be re-connected to the first slot 105. It is worth noting that the flip cover 3 at the position of the card block 302 has an arc structure protruding outward, and this arc structure coincides with the contour of the top of the handle 1. The flip cover 3 itself can not only seal the top of the handle 1 with the help of this arc structure, but also the doctor can more conveniently locate the specific positions of the card block 302 and the first slot 105 when pressing the card block 302. The above structural setting makes it easier for the doctor to add broken bones inside the handle 1, thereby improving the efficiency of the entire bone grafting process.

[0045] The implant tube 2 and the handle 1 are not an integrated fixed structure. The two are fixed by plugging the insertion rod 201 and the second slot 110. The plug 202 at the end of the insertion rod 201 is an elliptical structure. The front half of the slot is a cylindrical slot structure, and the back half is an elliptical slot structure that matches the shape of the plug 202. The cross-sectional area of ​​the plug 202 is larger than the cross-sectional area of ​​the front half of the insertion rod 201 and the second slot 110, but the inside of the plug 202 is a hollow structure. This arrangement allows the doctor to first align the plug 202 with the second slot 110 when using the insertion rod 201 and the second slot 110 to fix the implant tube 2 and the handle 1, and then press the insertion rod 201 hard. , so that the plug 202 is deformed and recessed into the hollow structure in the middle thereof. During the deformation of the plug 202, the insertion rod 201 can be inserted into the second slot 110. The insertion rod 201 continues to be inserted until the plug 202 is inserted into the end of the second slot 110. At this time, the plug 202 recovers its deformation and adapts to the contour of the rear half of the second slot 110, and achieves a limiting effect on the insertion rod 201. This installation method is not only simple in structure, but also convenient in operation. The implant tube 2 and the handle 1 can be disassembled and assembled at will with the help of the insertion rod 201 and the slot, which makes the two very convenient and efficient during cleaning and disinfection, thereby improving the practicality of the bone implanter.

[0046] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figures 6 to 8 As shown, the implant assembly is used to implant the broken bone into the intervertebral space of the patient, and the implant assembly is connected to the handle 1 and the implant tube 2 respectively. The implant assembly includes a slide plate 4 slidably connected to one side of the handle 1, a slide groove 109 is provided on the thumb pressing portion 102, a push rod 403 is fixedly connected to one side of the slide plate 4, and a piston 404 is rotatably connected to one end of the push rod 403, a support plate 5 is sleeved on the top outer wall of the implant tube 2, and an extrusion plate 6 is fixedly connected to one end of the bottom of the implant tube 2, a slider 401 is fixedly connected to one side of the slide plate 4, and one side of the slider 401 is fixedly connected The slide plate 4, the slider 401 and the connecting block 402 are connected in sequence as an integrated structure. The slide plate 4 and the push rod 403 are fixedly connected by the slider 401 and the connecting block 402. In the present application, the setting of the implant assembly further improves the efficiency of the bone crushing implantation process. The slide plate 4 is set at the position of the thumb pressing part 102, and the thumb pressing part 102 has a concave arc toward the middle direction of the grip 1. The slide plate 4 and the connecting block 402 are respectively installed on both sides of the slider 401. The size of the slide plate 4 and the connecting block 402 are larger than the slider 401. The size of the slider 401 is large, and the size of the slider 401 just matches the size of the slide groove 109. This arrangement allows the slider 401 to be limited in the slide groove 109 with the help of the slider 4 and the connecting block 402, thereby ensuring that the doctor can push the slider 4 to drive the slider 401 to slide in the slide groove 109, and the slider 401 will not be misaligned or offset during the sliding process with the help of the limiting effect of the slider 4 and the connecting block 402. A push rod 403 is installed on one side of the connecting block 402, and a piston 404 is installed on one end of the push rod 403. During the operation, the height of the piston 404 is also changing. It is worth noting that the reason why the thumb pressing portion 102 has a certain curvature is that when the doctor holds the handle 1, the thumb contacts the outer wall of the thumb pressing portion 102. This concave curvature can make it easier for the thumb to apply force to push the slide plate 4, thereby saving the doctor more effort during the actual operation. Because the doctor generally performs bone grafting with one hand during the actual operation, the way the bone grafter of the present application is held and the setting of the thumb sliding up and down to push the piston 404 can greatly reduce the doctor's operating burden and improve the efficiency of bone grafting.

[0047] In this embodiment, if Figure 2 , Figure 7 and Figure 8As shown, the inner wall of the handle 1 is fixedly connected with a first baffle 106 and a second baffle 107, the bottom end of the second baffle 107 is fixedly connected with an arc portion 108, and the top of the piston 404 is provided with an arc groove 405 consistent with the contour of the arc portion 108. As mentioned above, the doctor adds the broken bones into the inside of the handle 1 from the top of the handle 1. A total of two sets of baffles are arranged inside the handle 1. The installation position of the first baffle 106 is close to the inner wall of the finger fitting portion 101, and the installation position of the second baffle 107 is close to the inner wall of the finger fitting portion 101. The position is close to the push rod 403, and the first baffle 106 and the second baffle 107 can achieve a guiding effect on the broken bones. The broken bones falling from the top of the handle 1 will fall into the implant tube 2 under the guidance of the first baffle 106 and the second baffle 107. Furthermore, the installation position of the first baffle 106 is set to prevent the broken bones from being retained at the position of the finger fitting portion 101, and the installation position of the second baffle 107 is set to prevent the broken bones from leaking from the slide groove 109.

[0048] The piston 404 and the push rod 403 are rotatably connected together. Specifically, the top of the piston 404 uses a rotating shaft to penetrate the bottom end of the push rod 403. The rotating shaft is fixedly connected to the top of the piston 404, and the rotating shaft and the push rod 403 are rotatably connected. This arrangement allows the piston 404 to rotate unidirectionally at the bottom of the push rod 403 with the rotating shaft as the axis. The working principles of the rotating shaft and the push rod 403 are disclosed as prior art, so they are not described in detail. An arc portion 108 is provided at the end of the second baffle 107. The arc-shaped structure of the arc portion 108 coincides with the contour of the arc groove 405 on the surface of the piston 404. There are two states between the piston 404 and the push rod 403. Specifically, when the skateboard 4 slides to the top of the handle 1, the piston 404 rotates at the bottom of the push rod 403 with the help of the arc portion 108 and the arc groove 405. At this time, the piston 404 is folded and stored on one side of the second baffle 107 (such as Figure 8 As shown), in this state, the doctor can add bone fragments into the implant tube 2; when the slide plate 4 slides downward and leaves the limit of the second baffle 107, the piston 404 rotates again under its own gravity and is in a horizontal state (as shown in FIG. Figure 7 As shown), at this time, the piston 404 continues to slide downward to push the broken bones inside the implant tube 2 out.

[0049] In this embodiment, if Figure 1 , Figure 2 and Figures 9 to 11As shown, an expansion plate 601 is fixedly connected to one end of the bottom of the extrusion plate 6, a conical cylinder 602 is fixedly connected to one end of the top of the extrusion plate 6, a segmented groove 603 is provided at the middle position of the extrusion plate 6, the conical cylinder 602 is a conical structure recessed toward the middle, a recessed portion 604 is installed at the middle position of the extrusion plate 6, the recessed portion 604 is an arc-shaped structure recessed toward the middle, side plates 605 are fixedly connected to both sides of the expansion plate 601, and the thickness of the side plates 605 is less than the thickness of the expansion plate 601. When the piston 404 moves downward, it pushes the bone fragments inside the implant tube 2 to move toward the extrusion plate 6. The extrusion plate 6 is mainly composed of three parts: the expansion plate 601 at the bottom end, the conical cylinder 602 at the top end, and the recessed portion 604 at the middle position. The conical structure of the conical cylinder 602 is designed The arrangement enables the crushed bones to be squeezed when they are pushed to the position of the conical cylinder 602 by means of the structure that is recessed in the middle. When the piston 404 continues to push the crushed bones, the crushed bones will continue to squeeze the recessed portion 604 in the middle of the squeezing plate 6. Not only is a segmented groove 603 provided at the position of the recessed portion 604, but the plate body at the position of the recessed portion 604 is also thinned. This arrangement makes it easier for the recessed portion 604 to deform under the extrusion of an external force and to expand and deform outward. During the process of the recessed portion 604 expanding outward, a gap will be generated in the middle position thereof, thereby allowing the crushed bones to be discharged from the gap. The arrangement of the above structure prevents the crushed bones from being discharged outside the implant tube 2 under the extrusion of an external force, thereby ensuring that the crushed bones inside the bone implanter will not be washed away by water in a water environment during the bone grafting process.

[0050] Furthermore, when the extrusion plate 6 is squeezed and deformed, the expansion plate 601 connected thereto will also be deformed accordingly. The expansion plate 601 is also a segmented structure. The expansion plate 601 will expand outward under the drive of the extrusion plate 6. The expansion plate 601 has an arc-shaped structure protruding outward. The contour formed by the combination of multiple groups of expansion plates 601 can cover the broken bones. Specifically, when the broken bones are squeezed out of the extrusion part, the deformed expansion plate 601 will cover and limit the broken bones, thereby preventing the broken bones from floating upward with their own buoyancy and affecting the implantation effect.

[0051] In this embodiment, if Figure 2 , Figure 5 , Fig. 9 and Fig.10As shown, the support plate 5 is provided with a lightweight groove 501, and two rubber slides 502 are fixedly connected to the inner circumference of the support plate 5, and the rubber slides 502 are a curved sheet structure made of rubber material. The support plate 5 and the implant tube 2 can slide against each other. Specifically, the support plate 5 and the implant tube 2 are connected by two rubber slides 502, and the rubber slides 502 are a curved structure made of rubber material. Such an arrangement makes the friction between the rubber slides 502 and the implant tube 2 larger. When the doctor inserts the implant tube 2 into the surface of the support plate 5, the rubber slides 502 on the surface of the implant tube 2 will adhere to the outer wall of the implant tube 2, and use the friction force to push the support plate 5. The doctor can also pull the support plate 5 to adjust its height. The support plate 5 is a circular structure. During the actual operation, the doctor can let the support plate 5 contact the patient's skin surface and use the support effect of the support plate 5 on the implant tube 2 to assist in positioning. The support of the support plate 5 will not only reduce the burden of the doctor holding the handle 1, but also make the implant tube 2 more stable and the implantation efficiency higher during the bone crushing implantation. Since the doctor uses the lens to view the patient's tissue structure during the bone crushing implantation, the support plate 5 will not cause any obstruction to the surgical field. When the support plate 5 is used up, it can be directly unplugged and removed without affecting the cleaning and disinfection of the implant tube 2 and the handle 1.

[0052] The working principle of the technical solution provided by the present invention is as follows: when in use, the doctor needs to hold the grip 1 with his hand first. When the doctor holds the grip 1 with his hand, the finger fitting part 101 on one side of the grip 1 just fits with the doctor's four fingers except the thumb, and the doctor's thumb fits with the thumb pressing part 102, and the palm of the hand just wraps around the outside of the palm fitting part 103. The above structure is more in line with the contour of the human fingers in the gripping state, so that the doctor is more comfortable in the process of holding the grip 1, the gripping effect is better, it is more conducive to the doctor's one-handed operation, and the stability of the doctor during the one-handed operation is guaranteed. After holding the grip 1 tightly, The doctor pushes the blocking block 301 upward with his thumb, and the block 302 will be disengaged from the first slot 105 under the action of the thrust, and the flip cover 3 will also flip outward. The flip cover 3 will be deformed and bent during the flipping process. At this time, the top of the handle 1 is no longer blocked by the flip cover 3, and the doctor can add the broken bones from the top of the handle 1. When the broken bones are added, the doctor stops applying force to the flip cover 3, and the flip cover 3 can be reset with the help of its own structural characteristics. After resetting, the doctor manually presses the block 302 to re-engage the block 302 in the first slot 105. When the flip cover 3 is completely reset and re-fixed with the help of the block 302, the broken bones are added.

[0053] After the bone fragments are added, the doctor continues to hold the handle 1 to insert the implant tube 2 into the patient's body. After the position of the implant tube 2 is determined, the doctor slides to adjust the height of the support plate 5. The support plate 5 and the implant tube 2 are connected by two rubber slides 502. The rubber slides 502 are a curved surface structure made of rubber. This arrangement makes the friction between the rubber slides 502 and the implant tube 2 larger. When the doctor inserts the implant tube 2 into the surface of the support plate 5, the rubber slides 502 on the surface of the implant tube 2 will adhere to the outer wall of the implant tube 2 and fix the support plate 5 with the help of friction. The support plate 5 is a circular structure. When the height of the support plate 5 is determined, the doctor can let the support plate 5 contact the patient's skin surface and use the support effect of the support plate 5 on the implant tube 2 to assist in positioning. Under the support effect of the support plate 5, not only will the burden of the doctor holding the handle 1 be reduced, but also the implant tube 2 will be more stable during the bone fragment implantation process, and the implantation efficiency will be higher.

[0054] When it is necessary to implant the bone fragments into the intervertebral space of the patient, the doctor slides the slide plate 4 downward with the thumb to make the slide plate 4 drive the slide block 401 to slide in the slide groove 109. The slide block 401 will drive the push rod 403 to move downward during the sliding process. At this time, the piston 404 at one end of the push rod 403 will push the bone fragments in the implant tube 2 to move toward the extrusion plate 6. When the piston 404 moves downward, the bone fragments will be pushed to the position of the conical tube 602. At this time, the bone fragments are squeezed by the concave structure of the conical tube 602. When the piston 404 continues to push the bone fragments, the bone fragments will continue to squeeze the extrusion plate 6. The middle recessed portion 604 not only has a segmented groove 603 at the position of the recessed portion 604, but also the plate body at the position of the recessed portion 604 is thinned. This arrangement makes it easier for the recessed portion 604 to deform under the extrusion of an external force and to expand and deform outward. During the outward expansion of the recessed portion 604, a gap will be generated in the middle position thereof, thereby allowing the bone fragments to be discharged from the gap. The above structural arrangement prevents the bone fragments from being discharged outside the implant tube 2 under the extrusion of an external force, thereby ensuring that the bone fragments inside the bone implanter will not be washed away by water in a water environment during the bone grafting process.

[0055] During actual operation, there are two states between the piston 404 and the push rod 403. Specifically, when the slide plate 4 slides to the top of the handle 1, the piston 404 rotates at the bottom of the push rod 403 with the guidance of the arc portion 108 and the arc groove 405. At this time, the piston 404 is folded and stored on one side of the second baffle 107. In this state, the doctor can add crushed bones to the implant tube 2; when the slide plate 4 slides downward and disengages from the limit of the second baffle 107, the piston 404 rotates again under the action of its own gravity and is in a horizontal state. At this time, the piston 404 continues to slide downward to push the crushed bones inside the implant tube 2 out.
