Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an implant material syringe. Background Art

[0002] During the treatment of patients, doctors in the departments of stomatology and orthopedics often use implant materials to fill the bone defect sites of patients.

[0003] Taking the use of calcined bone powder as a filling material in stomatology as an example, when a dentist obtains the required calcined bone powder, the calcined bone powder is usually stored in a bottle or a box. The dentist needs to take out the calcined bone powder from the bottle or the box, and then gradually fill the calcined bone powder into the bone defect area. The filling process usually requires careful control of the volume and shape of the filling material to ensure tight combination with the surrounding bone tissue.

[0004] Currently, the way for dentists to fill calcined bone powder is to use a spoon to scoop up the bone powder in batches and then gradually and separately fill it into the bone defect area of the patient. The whole process is rather cumbersome in terms of operation steps. Summary of the Invention

[0023] A separable filter component, including: a separation filter screen, the pore size of the separation filter screen is smaller than the particle size of the implant material, and is used to separate the implant material from gas, liquid, and mixture.

[0024] In some embodiments, the implant material injection head and the implant material loading cylinder are detachable split components, and the outlet end of the implant material loading cylinder has a third detachable connection interface;

[0025] The implant material injection head has a fourth detachable connection interface that can be detachably connected to the third detachable connection interface;

Detailed implementation manners

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art based on this application belong to the scope of protection of the present invention.

[0049] Generally, a medical syringe usually consists of the following parts: a syringe barrel, a piston, and an injection needle. The syringe barrel is a hollow cylindrical container, usually made of transparent or semi-transparent material, for containing liquid medicine or injectable substances. The piston is a moving part inside the syringe barrel, usually made of rubber or plastic. It is in sealing cooperation with the inner wall of the syringe barrel, can push or draw liquid medicine, and injects the medicine into the medical object through the injection needle.

[0050] Among them, the inner diameter from the first end to the second end of the syringe barrel is the same, and the liquid medicine is sucked through the injection needle. However, the implanted materials involved in this solution, such as orthopedic implanted materials or dental restoration and filling materials, are usually solid substances, and it is impossible to perform the inhalation operation using an injection needle.

[0051] In addition, the caliber of the port of the syringe barrel is small, and it is difficult to fill the oral or bone implanted materials into a small syringe barrel with a diameter of 5 - 8 mm. It is difficult for doctors to fill the implanted materials into the syringe barrel by means of pouring. During the process of pouring the implanted materials into the syringe barrel with a small caliber, obvious scattering of the implanted materials will occur.

[0052] Therefore, an implanted material syringe proposed in the embodiments of the present invention can meet the injection use requirements of medical implanted materials. For example, the implanted material syringe can be applicable to orthopedic implanted materials, dental implanted materials, etc.

[0053] Specifically, a kind of implanted material syringe in the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0054] Figure 1It is a schematic structural diagram of an implant material syringe according to the first embodiment of the present invention. It should be noted that the implant material syringe of the embodiment of the present invention can be applied to the existing medical solid implant materials, such as: orthopedic implant materials, calcined bone powder, and for another example, dental implant materials, such as: filling material Geistlich Bio-Oss, Geistlich Bio-Oss can be used for dental implantation, playing the role of bone filling and guiding bone tissue regeneration. It is easy to understand that the field of application of the implant material syringe of the embodiment of this solution is not limited to being applicable only in orthopedic and dental implant materials, and can also be applicable to the filling fields of other medical implant materials, that is, the implant material syringe of the embodiment of the present invention is not limited to being used for orthopedic implant materials and dental implant materials, and is applicable to all powder or granular repair and filling materials.

[0055] As Figure 1 shown, the implant material syringe can be used to inject medical implant materials that play a role of occupying space and regeneration. The occupying role of the medical implant material can be understood as follows: The doctor can use the implant material syringe to inject the implant material into the area to be treated of the patient, and the implant material plays the role of filling or occupying the space of the area to be treated.

[0056] The implant material syringe includes: an implant material loading cylinder 10, an implant material loading funnel 20, an implant material injection head 30, and a push rod 40.

[0057] The caliber of the loading end of the implant material loading funnel 20 is larger than the inner diameter of the implant material loading cylinder 10, and the port of the discharging end of the implant material loading funnel 20 is used to load the implant material in the implant material loading funnel 20 into the entrance of the implant material loading cylinder 10. The implant material injection head 30 is located at the outlet end of the implant material loading cylinder 10. The push rod 40 includes: a piston 41, a connecting rod 42, and a pressing part 43. The two ends of the connecting rod 42 are respectively connected to the piston 41 and the pressing part 43. The piston 41 can enter the implant material loading cylinder 10 from the entrance of the implant material loading cylinder 10, and under the pressing thrust of the pressing part 43, the piston 41 pushes the implant material in the implant material loading cylinder 10 out through the implant material injection head 30.

[0058] In the technical solution provided by the embodiment of the present solution, when a doctor needs to use an implant material to treat a patient, the doctor can first load the implant material into the implant material loading funnel 20 from the loading end of the implant material loading funnel 20. Since the diameter of the loading end of the implant material loading funnel 20 is larger than the inner diameter of the implant material loading cylinder 10, the doctor can conveniently and quickly load the implant material through the implant material loading funnel 20 into the implant material loading cylinder 10. When it is necessary to fill the patient with the implant material, the push rod 40 can be operated to push the pressing part 43 to realize pushing the implant material out of the implant material injection head 30 and filling the area to be repaired of the patient. Compared with the prior art, the doctor can more conveniently fill the defective area of the patient with the implant material, rather than taking out the implant material in batches and then gradually and separately filling the implant material. The operation process of using this solution is more convenient and fast to realize pushing the implant material out of the implant material injection head 30 and filling the area to be repaired of the patient. Compared with the prior art, the doctor can more conveniently inject the implant material into the area to be treated of the patient, rather than taking out the implant material in batches and then gradually and separately filling the implant material, and the operation process is more convenient and fast.

[0059] When a doctor uses the implant material syringe provided by the embodiment of the present invention, taking a dentist as an example, the implant material can be calcined bone powder. When a dentist needs to fill the alveolar bone part of a patient with calcined bone powder, the dentist can pour the calcined bone powder in a bottle or box onto the loading end of the implant material loading funnel 20. The loading end of the implant material loading funnel 20 has a relatively large diameter, which can facilitate the loading operation of the calcined bone powder. It is easy to understand that direct pouring is only an embodiment of the operation. In actual use, it is not limited to the assistance of other tools such as a spatula for loading operation.

[0060] In the prior art, due to the small volume of the spatula, it is necessary to take the calcined bone powder in multiple times. In this solution, the dentist can load a large amount of calcined bone powder into the implant material loading cylinder 10. Then, align the implant material injection head 30 with the part to be repaired of the patient, and the pressing part 43 of the push rod 40 can be pressed to fill the calcined bone powder in the implant material loading cylinder 10 into the area to be treated at one time. The dentist can conveniently and quickly perform the repair operation on the designated part.

[0061] Among them, during implementation, as Figure 1 shown, the injection direction of the implant material injection head 30a is the same as the extension direction of the implant material loading cylinder 10 in the length direction. That is, the implant material injection head 30a can be in a straight head shape, and the length extension direction of the implant material loading cylinder 10 is the same as the injection direction of the implant material injection head 30a.

[0062] In the field of stomatology, when a dentist fills an implant material into the filling area of a patient, the straight implant material injection head 30 is difficult to operate. Figure 2 It is a schematic structural diagram of an implant material syringe according to the second embodiment of the present invention. As Figure 2 shown, in this solution, the implant material injection head 30b is bent, and the injection direction of the implant material injection head 30b forms a preset angle with the extending direction of the implant material loading cylinder 10 in the length direction. The preset angle can be between 5° and 90°. The dentist can conveniently inject the implant material into the filling area of the patient's oral cavity.

[0063] In some embodiments, the inner diameter of the implant material injection head 30 can be smaller than the inner diameter of the implant material loading cylinder 10, or the inner diameter of the implant material injection head 30 can also be equal to the inner diameter of the implant material loading cylinder 10.

[0064] As Figure 1 and Figure 2 shown, in some embodiments, the implant material injection head 30 and the implant material loading cylinder 10 can be of an integral structure. In implementation, an integral molding process can be used to form an integrally molded component. For example, using a plastic material and an injection molding process to prepare the integrally structured implant material injection head 30 and the implant material loading cylinder 10.

[0065] In the actual application process, after the implant material syringe is produced, it will also involve storage, transportation, sales and other links. In order to facilitate the separate packaging of the implant material injection head 30 and the implant material loading cylinder 10. Figure 3 It is a schematic structural diagram of an implant material syringe according to the third embodiment of the present invention. Figure 4 It is a disassembled structural diagram of an implant material syringe according to the third embodiment of the present invention. As Figure 3 and Figure 4 shown, in some embodiments, the implant material injection head 30 and the implant material loading cylinder 10 can be of a split structure, and the implant material injection head 30 and the implant material loading cylinder 10 are detachable split components, such as split components that can achieve threaded detachable connection or plug-in detachable connection.

[0066] Among them, the implant material loading cylinder 10 can be made of a transparent material or a translucent material, which is convenient for doctors to observe the remaining amount of the implant material inside. Specifically, a remaining amount scale mark can be engraved on the barrel wall of the implant material loading cylinder 10 to facilitate directly reading the remaining amount data of the implant material.

[0067] The implant material loading cylinder 10 is a circular cylinder with a diameter that can be 5 - 12 mm. Since the amount of implant material used is usually small, an implant material syringe with a small diameter size can be configured. It is easy to understand that for cases where the amount of implant material used is large, an implant material loading cylinder 10 with a larger diameter as required can also be set.

[0068] As Figure 1 shown, the implant material filling funnel 20 is a circular funnel, and the caliber of the port at the discharging end of the implant material filling funnel 20 corresponds to the caliber of the inlet of the implant material loading cylinder 10, and can be equal, for example. The implant material filling funnel 20 can also be of other shapes, such as a rectangular funnel, a triangular funnel, an oval funnel, etc.

[0069] The opening angle of the implant material filling funnel 20 can be understood as the included angle formed between the inner walls of the funnel on both sides of its axis in the axial section of the implant material filling funnel 20. The opening angle of the implant material filling funnel 20 can be between 80° and 170°. The larger the opening size, the less likely it is for the implant material to leak when filling the implant material.

[0070] As Figure 1 shown, the implant material loading cylinder 10 and the implant material filling funnel 20 can be of an integral structure. In implementation, an integral molding process can be used to form an integrally molded component. For example, using a plastic material and an injection molding process to prepare the integrally structured implant material loading cylinder 10 and the implant material filling funnel 20.

[0071] In the actual application process, after the implant material syringe is produced, it will also involve links such as storage, transportation, and sales. The space occupied by the implant material syringe will directly affect the costs incurred in links such as storage, transportation, and sales. Since the plane where the port at the discharging end of the implant material filling funnel 20 is located is perpendicular to the axis of the implant material loading cylinder 10, therefore, the space occupied by the integrally structured implant material loading cylinder 10 and the implant material filling funnel 20 is a three-dimensional geometric structure, and it is difficult to compress the space they occupy during the storage of a large number of implant material syringes.

[0072] In some embodiments provided by the present invention, as Figure 3 and Figure 4 shown, the implant material loading cylinder 10 and the implant material filling funnel 20 are detachable and separable components. The implant material loading cylinder 10 and the implant material filling funnel 20 can be placed separately before use. And during use, the two can be combined and used together.

[0073] Specifically, the port of the discharge end of the implant material loading funnel 20 has a first detachable connection interface 21, and the inlet of the implant material loading cylinder 10 has a second detachable connection interface 11 that can be detachably connected to the first detachable connection interface 21. The first detachable connection interface 21 and the second detachable connection interface 11 are threaded connection interfaces. Alternatively, the first detachable connection interface 21 and the second detachable connection interface 11 are plug-in interfaces. That is, the first detachable connection interface 21 and the second detachable connection interface 11 can be connected by threading or by plugging.

[0074] In some embodiments, the inner diameter of the first detachable connection interface 21 is the same as the outer diameter of the second detachable connection interface 11, and the caliber of the discharge end port of the implant material loading funnel 20, the inner diameter of the implant material loading cylinder 10, and the outer diameter of the piston 41 are the same. Figure 5 It is a schematic structural diagram of an implant material syringe according to the fourth embodiment of the present invention. Figure 6 is Figure 5 The enlarged view of A in. During implementation, as Figure 5 and Figure 6 shown, the inner diameter of the first detachable connection interface 21 is greater than the inner diameter of the second detachable connection interface 11, and the inner wall of the first detachable connection interface 21 and the outer wall of the second detachable connection interface 11 are detachable connection surfaces. The detachable connection surface can be a threaded surface or a plug-in surface.

[0075] Or, the outer diameter of the first detachable connection interface 21 is the same as the inner diameter of the second detachable connection interface 11, the inner diameter of the first detachable connection interface 21 is smaller than the inner diameter of the second detachable connection interface 11, and the outer wall of the first detachable connection interface 21 and the inner wall of the second detachable connection interface 11 are detachable connection surfaces. The outer wall of the first detachable connection interface 21 and the inner wall of the second detachable connection interface 11 are detachable connection surfaces. The detachable connection surface can be a threaded surface or a plug-in surface. In such an implementation, the outlet of the implant material loading funnel 20 is thinner than the inlet of the implant material loading cylinder 10, so that the implant material powder is not easily scattered onto the outer wall of the implant material loading cylinder 10. When injecting the implant material, the implant material loading cylinder 10 and the implant material loading funnel 20 can be separated, and then the push rod 40 can be inserted into the implant material loading cylinder 10.

[0076] Or, Figure 7 It is a schematic partial structure diagram of an implant material syringe according to the fifth embodiment of the present invention. As Figure 7As shown, the outer wall of the first detachable connection interface 21 and the inner wall of the second detachable connection interface 11 are detachable connection surfaces, and the inner diameter of the first detachable connection interface 21 is equal to the inner diameter of the second detachable connection interface 11. The detachable connection surface can be a threaded surface or a plug-in surface. In such an implementation, the inner diameters of the outlet of the implant material loading funnel 20 and the inlet of the implant material loading cylinder 10 are the same. Thus, in the implant material to be injected, the push rod 40 can be directly inserted into the implant material loading cylinder 10 through the first detachable connection interface 21 and the second detachable connection interface 11.

[0077] Of course, in practice, a leak-proof connection can be formed between the port at the discharge end of the implant material loading funnel 20 and the inlet of the implant material loading cylinder 10.

[0078] The second detachable connection interface 11 is located at the end of the implant material loading cylinder 10. The inner diameter of the second detachable connection interface 11 is the same as the inner diameter of the implant material loading cylinder 10, and the outer diameter of the second detachable connection interface 11 is the same as the outer diameter of the implant material loading cylinder 10. The diameter of the port at the discharge end of the implant material loading funnel 20 is smaller than the inner diameter of the first detachable connection interface 21. When the diameter of the port at the discharge end of the implant material loading funnel 20 is equal to the inner diameter of the second detachable connection interface 11, the diameter of the port at the discharge end of the implant material loading funnel 20 can be the same as the diameter of the inlet of the implant material loading cylinder 10, so that the implant material in the implant material loading funnel 20 can slide well into the inlet of the implant material loading cylinder 10. It can be understood that if the diameter of the port at the discharge end of the implant material loading funnel 20 is larger than the diameter of the inlet of the implant material loading cylinder 10, then a platform will be formed at the inlet of the implant material loading cylinder 10, and there will be a problem that the implant material is likely to remain (due to the existence of the platform, it is difficult for the implant material on the platform to slide into the inlet of the implant material loading cylinder 10).

[0079] After the doctor loads the solid implant material into the implant material syringe, it can be directly filled into the area to be treated by injection. In some cases, due to factors such as the doctor's lack of proficiency in operation, the solid implant material may not be densely loaded in the implant material loading cylinder 10. That is, there may be some gas filled in the implant material in the implant material loading cylinder 10. If so, when the doctor uses the implant material syringe to inject the implant material, on the one hand, there may be bubbles in the implant material injected into the area to be treated by the patient, resulting in poor filling effect. On the other hand, it may also affect the doctor's misjudgment of the actual volume of the implant material in the implant material loading cylinder 10. At the same time, some implant materials are used in combination with body fluids such as normal saline, blood, or bone marrow fluid. Therefore, it is necessary to be able to suck the liquid into the implant material loading cylinder 10, mix it evenly with the implant material, and then push out the excess liquid and bubbles from the implant material loading cylinder 10.

[0080] The implant material can be a solid orthopedic repair and filling material, dental repair and filling material, or soft tissue repair and filling material.

[0081] Based on the above problems and requirements, the above implant material syringe further includes: a separation filter screen 51, the aperture of the separation filter screen 51 is smaller than the particle size of the implant material, and is used to separate the implant material from gas, liquid, and mixture. The separation filter screen 51 can realize the separation of solid implant material, gas, and liquid, and is used to separate the implant material from the gas and excess liquid mixed in the implant material.

[0082] During use, the implant material is mixed with body fluids such as normal saline, blood, or bone marrow fluid and excess bubbles in the implant material loading cylinder 10. The separation filter screen 51 can be covered at the outlet end of the implant material injection head 30. Then, the pressing part 43 of the push rod 40 is pushed, so that the piston 41 squeezes the implant material in the implant material loading cylinder 10. Under the pressure of the piston 41, the gas in the implant material will be discharged from the inside of the implant material loading cylinder 10 through the separation filter screen 51, while the implant material is blocked by the separation filter screen 51 and still remains in the implant material loading cylinder 10. After exhausting gas and discharging liquid, the separation filter screen 51 and the implant material injection head 30 can be separated, and then the subsequent steps of filling the implant material into the area to be treated can be continued.

[0083] Among them, the separation filter screen 51 can be manually covered by the doctor on the implant material injection head 30. However, it is easy to have the situation of incomplete coverage, and there is a possibility of implant material overflowing from the implant material injection head 30. Further, to solve the above problems, Figure 8 It is a schematic structural diagram of an implant material syringe according to the sixth embodiment of the present invention. Figure 9Schematic diagram of the separable filter component 50 in the implant material syringe according to the sixth embodiment of the present invention. Please refer to Figure 4 , Figure 8 and Figure 9 As shown, in the above-mentioned implant material syringe, the implant material injection head 30 and the implant material loading cylinder 10 are detachable and separable components. The outlet end of the implant material loading cylinder 10 has a third detachable connection interface 111. The implant material injection head 30 has a fourth detachable connection interface 301 that can be detachably connected to the third detachable connection interface. The filter component 50 further includes: a separation joint 52. The first end of the separation joint 52 has a fifth detachable connection interface 521 that can be detachably connected to the third detachable connection interface. The second end of the separation joint 52 has a discharge port 522. The middle part of the separation joint 52 has a filtering space communicating the third detachable connection interface 521 and the discharge port 522. The separation filter screen 51 for separating gas, liquid and the implant material is arranged in the filtering space.

[0084] During use, the separation joint 52 can be first connected to the implant material loading cylinder 10 and provided to the doctor in advance. With the separation filter screen 51, by operating the push rod 40, blood or physiological saline is inhaled into the implant material loading cylinder 10, and the piston 41 is pushed up and down several times to mix the implant material in the implant material loading cylinder 10 with the inhaled liquid. Among them, in this process, excess gas will be inhaled and there will also be excess liquid. After the doctor finishes mixing, by pushing the push rod 40 to squeeze the piston 41, the gas and excess liquid can be extruded from the implant material loading cylinder 10, and the solid implant material still remains in the implant material loading cylinder 10, so that the mixing of the implant material with physiological saline or body fluids such as blood and bone marrow fluid can be completed quickly and efficiently. After exhausting the gas and discharging the excess liquid, the subsequent steps of filling the implant material can be continued. The whole process is relatively convenient to operate, and during the process of exhausting the gas and discharging the excess liquid, it is not easy to have the problem of leakage of the implant material.

[0085] After the implant material is filled and mixed with the liquid, and the gas and excess liquid are exhausted, when it is time to inject, the separation joint 52 can be detached from the implant material loading cylinder 10, and the implant material injection head 30 can be assembled with the implant material loading cylinder 10, and then the subsequent implant material injection steps can be carried out.

[0086] Generally, when a doctor uses an implant material syringe to inject an implant material, for the convenience of exerting force, such as Figure 2As shown, it is usually achieved by pressing the implant material loading cylinder 10 with the index finger and middle finger, and then pressing the pressing portion 43 of the push rod 40 with the thumb. Therefore, in order to facilitate the doctor's use, independent index finger and middle finger pressing plates can be provided on both sides of the implant material loading cylinder 10. However, in practice, this will make the structure complex. In some embodiments, the surface of the implant material filling funnel 20 close to the implant material injection head 30 can be used as the pressing surface 201 for the index finger and middle finger of the implant material syringe. That is, the index finger and middle finger are pressed against the surface of the implant material filling funnel 20 close to the implant material injection head 30, and then the pressing portion 43 of the push rod 40 is pressed with the thumb to realize the injection process of the implant material. The operation is relatively convenient and the structure is simple.

[0087] Since the implant material filling funnel 20 is a conical structure, the angle between the surface of the implant material filling funnel 20 close to the implant material injection head 30 and the outer wall of the implant material loading cylinder 10 is usually an acute angle. When the doctor uses the implant material syringe to inject the implant material, if the hand slips, it is easy to cause the index finger or middle finger to slip away from the pressing surface of the implant material filling funnel 20. Therefore, in some implementations, Figure 10 is a schematic structural diagram of an implant material syringe according to the seventh embodiment of the present invention, as Figure 10 shown, the pressing surface of the implant material filling funnel 20 is a plane 201a perpendicular to the outer wall of the implant material loading cylinder 10. Or, in some embodiments, Figure 11 is a schematic structural diagram of an implant material syringe according to the eighth embodiment of the present invention, as Figure 11 shown, at least two concave pressing surfaces 201b are provided on the pressing surface of the implant material filling funnel 20, and the at least two concave pressing surfaces 201b are distributed on both sides of the implant material loading cylinder 10. Compared with the pressing surface of the planar structure, when using the concave pressing surface, the doctor's index finger and middle finger can form a more powerful cooperation with the two concave pressing surfaces 201b during the injection of the implant material with the implant material syringe.

[0088] Specifically, Figure 12 is a schematic diagram of the sub-packaging structure of an implant material syringe according to the ninth embodiment of the present invention, as Figure 12As shown, the implant material loading cylinder 10, the implant material filling funnel 20, the implant material injection head 30, the push rod 40, and the filtering component 50 are five sub-packaging components. The implant material loading cylinder 10, the implant material filling funnel 20, the implant material injection head 30, the push rod 40, and the filtering component 50 can be respectively laid flat in the sub-packaging body 100. That is, the sub-packaging body 100 includes: a first sub-packaging space, a second sub-packaging space, a third sub-packaging space, a fourth sub-packaging space, and a fifth sub-packaging space that are laid flat. The implant material loading cylinder 10, the implant material filling funnel 20, the implant material injection head 30, the push rod 40, and the filtering component 50 are sequentially arranged in the first sub-packaging space, the second sub-packaging space, the third sub-packaging space, the fourth sub-packaging space, and the fifth sub-packaging space. This can facilitate large-scale stacking and save space.

[0089] Of course, it is easy to understand that in implementation, the implant material loading cylinder 10, the implant material filling funnel 20, the implant material injection head 30, the push rod 40, and the filtering component 50 are not limited to being placed in one sub-packaging body 100, and can also be respectively placed in different bag bodies. Some components can be assembled and stored together. For example, at least two of the implant material loading cylinder 10, the implant material injection head 30, the push rod 40, and the filtering component 50 can be assembled and stored in one sub-packaging space.

[0090] In implementation, the sub-packaging body 100 can be a sterilized transparent plastic box with grooves, or a sterilized transparent plastic bag.
