Description

Technical Field

[0001] The utility model relates to the technical field of bone powder filling equipment, in particular to a bone powder filling equipment for oral implantation. Background Art

[0002] The main function of bone meal filling equipment is to transport bone meal from containers or storage tanks to the surgical area.

[0003] As one of the three major restoration technologies for tooth loss, oral implant technology has developed rapidly to this day. As far as maxillary posterior implants are concerned, the remaining bone height of the maxillary sinus floor is insufficient in most patients. For the insufficient height of the sinus floor bone caused by maxillary sinus pneumatization, maxillary sinus floor lift has become the standard solution to this problem. According to the different approaches to the sinus floor, maxillary sinus floor lift is divided into two clinical procedures: transalveolar ridge maxillary sinus floor lift and lateral wall fenestration maxillary sinus floor lift. The most commonly used maxillary sinus floor lift through lateral wall fenestration is to open a bone window on the outer wall of the maxillary sinus as an approach, peel off and lift the sinus floor mucoperiosteum, implant bone augmentation material between the sinus floor bone surface and the mucoperiosteum to increase the sinus floor bone height, and implant implants at the same time or in stages.

[0004] According to a bone powder filler for oral implants disclosed in patent No. CN213130059U, the device is easy to control bone powder, avoids waste of bone powder, is simple to operate, and improves work efficiency. However, in actual applications, the operating space is small, the amount of implanted material is large, and the surgical site is deep, so there is a problem of inconvenient filling operation; for this reason, we provide a bone powder filling device for oral implants to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a bone powder filling device for oral implantation. The device is more convenient and quick when filling bone powder and can effectively improve the efficiency of bone powder transportation.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bone powder filling device for oral implantation, comprising a handle, a driving mechanism is arranged inside the handle, the left end and the right end of the handle are fixedly connected to connecting tubes, the ends of the two connecting tubes away from each other are fixedly connected to bone powder loading grooves, the inner walls of the two bone powder loading grooves are slidably connected to conveying sliders, and two symmetrical soft steel wires are arranged inside the handle, and the ends of the two soft steel wires away from each other are respectively fixedly connected to the outer surfaces of two conveying sliders.

[0007] Furthermore, the driving mechanism includes a central slider, the outer surface of which is slidably connected to the inner wall of the handle, and the left and right sides of the central slider are respectively fixedly connected to one end of two soft steel wires close to each other. The soft steel wires can be driven to move by the central slider. The outer surface of the central slider is polished to reduce the wear caused by the sliding of the central slider. The central slider is made of titanium alloy, which can avoid harm to the patient's body and prevent the device from rusting and corrosion.

[0008] Furthermore, a push piece is fixedly connected to the outer surface of the central slider, and the inner wall of the push piece is slidably connected to the outer surface of the handle. The push piece allows the staff to push the central slider to move more conveniently and quickly. Because the inner wall of the central slider is in direct contact with the outer surface of the handle, the inner wall of the push piece needs to be polished to reduce the wear of the push piece on the handle when it slides.

[0009] Furthermore, the outer surface of the push piece is provided with anti-slip grooves, and the outer surface of the push piece is covered with a protective cover. The anti-slip grooves on the outer surface of the push piece can effectively prevent medical staff from slipping when pushing the central sliding block and causing excessive filling of bone powder. The protective cover on the outer surface of the push piece can protect the medical staff and prevent them from being scratched.

[0010] Furthermore, the handle and the connecting tube form an angle of 120°, and the connecting tube and the bone powder loading slot form an angle of 45°. By setting the angle between the handle and the connecting tube to 120°, the handle can more conveniently avoid obstruction of the lips and cheeks when stopping at the bone powder. Because the internal space of the oral cavity is too small, setting the angle between the connecting tube and the bone powder loading slot to 45° can make it more convenient for medical staff to fill the bone powder.

[0011] Furthermore, the outer surface of the handle is provided with anti-slip grooves, and the outer surface of the handle is covered with a protective cover. The anti-slip grooves on the outer surface of the handle can make medical staff safer during surgery and avoid hand slipping during use, and the protective cover on the outer surface of the handle can make medical staff more comfortable.

[0012] Compared with the prior art, the bone powder filling device for oral implantation has the following beneficial effects:

The utility model can make it more convenient for medical staff to hold the device for work through the handle, and can connect the handle and the bone powder loading tank through the connecting tube. The driving mechanism can make it more convenient for staff to push the soft steel wire to move. The soft steel wire can push the conveying slider to slide, and the movement of the conveying slider can push the bone powder in the bone powder loading tank to the surgical area, which can make it more convenient and quick for medical staff to fill the bone powder, and can effectively improve the efficiency of bone powder delivery.

[0014] 2. The utility model can make it more convenient for medical staff to push the bone powder loading tank to move by using the central slider and the push piece. By setting the angle between the handle and the connecting tube to 120°, the handle can more conveniently avoid the obstruction of the lip and cheek when stopping at the bone powder. By setting the angle between the connecting tube and the bone powder loading tank to 45°, it can be more convenient for medical staff to fill the bone powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] As described in the background art, there is a problem of inconvenient filling operation. For this reason, this embodiment provides a bone powder filling device for oral implantation. The device is more convenient and quick when filling bone powder, and can effectively improve the efficiency of bone powder transportation.

[0022] See also Figures 1 to 4 This embodiment provides a bone powder filling device for oral implantation, including a handle 1, see Figure 1Because the device needs to work inside the patient's mouth, the device needs to be cleaned in time after use. The handle 1 can be made of a waterproof and rust-proof material that does not cause harm to the human body, which can protect the patient.

[0023] The outer surface of the handle 1 is provided with anti-slip grooves, and the outer surface of the handle 1 is covered with a protective cover. The anti-slip grooves on the outer surface of the handle 1 can make medical staff safer during surgery and avoid hand slipping during use. The protective cover on the outer surface of the handle 1 can make medical staff more comfortable.

[0024] A driving mechanism 2 is disposed inside the handle 1 . The left and right ends of the handle 1 are fixedly connected to connecting tubes 3 . The ends of the two connecting tubes 3 that are away from each other are fixedly connected to bone powder loading slots 4 .

[0025] See also Figure 1 to Figure 2 The connecting tube 3 serves the purpose of connecting the bone powder loading slot 4. The two bone powder loading slots 4 at both ends of the device are respectively suitable for operations at the left and right ends, which can make it more convenient for medical staff to perform operations. At the same time, setting the bone powder loading slot 4 to a groove shape can make it more convenient for medical staff to fill bone powder, and the ends of the two bone powder loading slots 4 away from each other are both open-type designs.

[0026] The handle 1 and the connecting tube 3 form an angle of 120°, and the connecting tube 3 and the bone powder loading slot 4 form an angle of 45°. By setting the angle between the handle 1 and the connecting tube 3 to 120°, the handle 1 can more conveniently avoid the obstruction of the lips and cheeks when inserting the bone powder. Because the internal space of the oral cavity is too small, setting the angle between the connecting tube 3 and the bone powder loading slot 4 to 45° can make it more convenient for medical staff to fill the bone powder.

[0027] The inner walls of the two bone powder loading grooves 4 are slidably connected with a conveying slider 6. The bone powder inside the bone powder loading groove 4 can be pushed into the surgical area by moving the conveying slider 6. The outer surface of the conveying slider 6 is polished, which can reduce the wear caused by the sliding of the conveying slider 6 and effectively increase the service life of the device. The conveying slider 6 is provided with a groove, which is adapted to the protrusion on the bone powder loading groove 4, which can effectively prevent the conveying slider 6 from being dislocated during the sliding process.

[0028] Two symmetrical soft steel wires 5 are arranged inside the handle 1, and the ends of the two soft steel wires 5 that are away from each other are fixedly connected to the outer surfaces of the two conveying slide blocks 6, respectively. Figures 2 to 3 The movement of the soft steel wire 5 can drive the conveying slider 6 to move. The soft steel wire 5 has a certain strength, which can enable the device to push the slider 6 to move back and forth during operation. At the same time, the soft steel wire 5 must have a certain toughness so that it can operate normally inside the angled lumen in the device.

[0029] The driving mechanism 2 includes a central slider 201, the outer surface of which is slidably connected to the inner wall of the handle 1, and the left and right sides of the central slider 201 are respectively fixedly connected to the ends of two soft steel wires 5 that are close to each other. The soft steel wires 5 can be driven to move by the central slider 201. The outer surface of the central slider 201 is polished to reduce the wear caused by the sliding of the central slider 201. The central slider 201 is made of titanium alloy, which can avoid harm to the patient's body and prevent the device from rusting and corrosion.

[0030] The outer surface of the central slider 201 is fixedly connected with a push piece 202, and the inner wall of the push piece 202 is slidably connected to the outer surface of the handle 1. The push piece 202 can make it more convenient and quick for the staff to push the central slider 201 to move. Because the inner wall of the central slider 201 is in direct contact with the outer surface of the handle 1, the inner wall of the push piece 202 needs to be polished to reduce the wear of the push piece 202 on the handle 1 when it slides.

[0031] The outer surface of the push piece 202 is provided with anti-slip grooves, and the outer surface of the push piece 202 is covered with a protective cover. The anti-slip grooves on the outer surface of the push piece 202 can effectively prevent the medical staff from slipping when pushing the central slider 201 and causing excessive filling of bone powder. The protective cover on the outer surface of the push piece 202 can protect the medical staff and prevent them from being scratched.

[0032] Working principle: When the device is in use, bone powder is first loaded into the bone powder loading slot 4 on one side of the operating area, and then the end of the bone powder loading slot 4 is slightly inserted into the maxillary sinus along the bone window on the side wall of the maxillary sinus, and then the push piece 202 is pushed. The push piece 202 can drive the central slider 201 to slide on the inner wall of the handle 1, and then the soft steel wire 5 can be pushed to move. With the movement of the soft steel wire 5, the conveying slider 6 can be pushed to slide inside the bone powder loading slot 4, so that the bone powder can be pushed into the operating area, and then the filling of the bone powder can be completed.
