Description

Technical Field

[0001] This invention relates to the field of oral treatment technology, specifically to a modified maxillary sinus external lifting bevel chisel used in oral implant restoration surgery. Background Technology

[0002] Bone chisels are mainly composed of a chisel head and a chisel body. The chisel head can be divided into straight, curved, straight-curved, double-curved, right-angled, arc-shaped, double-slanted flat-blade, curved double-slanted flat-blade, and round-blade types according to its shape. The chisel body can be divided into round handle, hexagonal handle, flat round handle, flat square handle, and square handle types according to the difference in the handle. The bone chisel has a short and thick cutting edge, and the end of the chisel handle is an enlarged circular flat surface, which is convenient for using a bone hammer when removing bone. The bone chisel has a relatively thick cutting edge and high strength.

[0003] Dental implant restoration is a common method used to restore the function and appearance of missing teeth. Maxillary sinus lift surgery often uses a transsinusoidal approach (through the sinus floor or lateral window) to increase the height of the maxilla through techniques such as periosteal lifting or bone graft implantation. However, these methods have limitations, such as significant surgical trauma, postoperative pain, and postoperative complications. The design of inclined plane bone chisels can minimize surgical trauma and reduce the risk of postoperative complications.

[0004] According to Chinese Publication No. CN104605915A, a maxillary sinus lift bone chisel is disclosed, including a working end and a handle. The working end has a groove for peeling away the sinus floor mucosa to expand the range of maxillary sinus lift. The end face of the working end is flat, and the thickness of the end face is 0.3mm-1.5mm. By adding a groove to the working end of the existing "cylindrical" bone chisel, it is made into a "semi-cylindrical" or "incompletely cylindrical" shape. When using the improved bone chisel for maxillary sinus lift, provided that the implant socket of the same diameter is prepared, the bone chisel can peel away the sinus floor mucosa to expand the range of maxillary sinus lift after penetrating deep into the maxillary sinus, thereby increasing the magnitude of maxillary sinus lift.

[0005] According to Chinese Publication No. CN213665880U, this invention belongs to the field of minimally invasive oral implant technology, and specifically relates to a set of beveled bone chisels suitable for maxillary sinus lift in oral implant surgery. The beveled bone chisel tool for maxillary sinus lift in oral implant surgery includes a handle, a chisel rod, and a chisel blade. The handle is connected vertically to the chisel rod, and the chisel blade is located at the top of the chisel rod, with a beveled edge. This tool reduces the risk of maxillary sinus mucosal perforation, making the surgery safer and easier to operate. It has a simple structure, is convenient to operate, and is inexpensive.

[0006] However, most existing beveled bone chisels adopt a one-piece structure, which cannot be finely adjusted to meet the needs of bone chiseling in small openings. Summary of the Invention

[0007] To address the problems in the prior art, this invention provides a modified maxillary sinus external lifting bevel chisel for oral implant restoration surgery.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a modified maxillary sinus external lifting oblique bone chisel for oral implant restoration, including a chisel head processing frame, a connecting assembly frame, a docking nesting frame and a supporting middle frame. The lower end of the chisel head processing frame is fixedly connected to the connecting assembly frame, the lower end of the connecting assembly frame is fixedly connected to the docking nesting frame, and the lower end of the docking nesting frame is fixedly connected to the supporting middle frame.

[0009] The lower end of the supporting frame is fixedly connected to a fastening bracket, the lower end of the fastening bracket is fixedly connected to a first supporting reinforcing hoop, the side end of the first supporting reinforcing hoop is fixedly connected to a combined crossbar, and the side end of the second supporting reinforcing hoop is fixedly connected to a second supporting reinforcing hoop.

[0010] The lower end of the second support reinforcing hoop is fixedly connected to a fixed connecting frame, and the lower end of the fixed connecting frame is fixedly connected to an adjustment and processing component. Through the structural arrangement of the chisel head processing frame, connecting combination frame, docking nesting frame, and support middle frame, the upper support work can be performed. The user can hammer the chisel head processing frame, so that the chisel head processing frame transmits force. The lower end of the chisel head processing frame is fixed to the connecting combination frame, docking nesting frame, and support middle frame to realize the support force transmission function. The lower end of the support middle frame is fixed to the cooperating fastening frame. The cooperating fastening frame is fixed to the second support reinforcing hoop through the first support reinforcing hoop, the combined crossbar, and the second support reinforcing hoop to realize the structural support work. The lower end of the second support reinforcing hoop is fixed to the adjustment and processing component through the fixed connecting frame, thereby realizing the chiseling work.

[0011] Specifically, the control and processing component includes a fastening end frame, a supporting base frame, and an adapter frame. The lower end of the fastening end frame is fixedly connected to the supporting base frame, and the lower end of the supporting base frame is fixedly connected to the adapter frame.

[0012] Specifically, the control and processing component also includes a fixed locking sleeve frame, an adjusting chisel rod, an adapter groove, a fastening rotating rod, and a threaded mating rod. The lower end of the adapter frame is fixedly connected to the fixed locking sleeve frame, and the center of the fixed locking sleeve frame is slidably connected to the adjusting chisel rod, which has an adapter groove.

[0013] Specifically, the fixed locking sleeve is threadedly connected to a threaded mating rod, and a fastening rotating rod is fixedly connected to the side end of the threaded mating rod. By adjusting the structure of the processing component, adjustments can be made to reduce the bottom area, thereby allowing for fine adjustments to meet the requirements of bone chiseling work at the small opening position. The adjusting chisel rod can be adjusted relative to the fixed locking sleeve. Then, the fastening rotating rod is screwed on, causing the fastening rotating rod to drive the threaded mating rod to rotate. The threaded mating rod passes through the fixed locking sleeve and connects to the matching groove on the adjusting chisel rod, thereby positioning the matching groove and realizing the adjustment of the bottom area to achieve bone chiseling work at the small opening position.

[0014] Specifically, the adapter groove on the adjusting chisel rod is threadedly connected to the threaded rod.

[0015] Specifically, the adjusting chisel is built into the center of the support base, and the adjusting chisel can be adjusted.

[0016] Specifically, the diameter of the adapter groove is half the diameter of the fixed locking sleeve frame, and the upper end of the fastening end frame is fixedly connected to the fixed connecting frame.

[0017] Specifically, a movable ball sleeve is fixedly connected to the side end of the combined crossbar, an adjusting limit rod is inserted into the center of the movable ball sleeve, a fastening washer is screwed onto the adjusting limit rod, and a ball stick is movably connected to the bottom end of the movable ball sleeve.

[0018] The beneficial effects of this invention are:

[0019] I. This invention, through the structural arrangement of a chisel head processing frame, a connecting assembly frame, a docking nesting frame, and a supporting middle frame, enables upper support work.

An adjusting limit rod 21 is inserted into the center of the movable ball sleeve 19. A fastening washer 20 is screwed onto the adjusting limit rod 21. A ball stick 22 is movably connected to the bottom end of the movable ball sleeve 19.

[0044] In this embodiment, the movable ball sleeve 19 and the cue stick 22 are adjustable. The movable ball sleeve 19 rotates on the cue stick 22 by adjusting the limiting rod 21 to adjust to a suitable position to prevent obstruction. Then, the fastening shim 20 is screwed on to press the movable ball sleeve 19. At this time, the movable ball sleeve 19 and the cue stick 22 are positioned to achieve a tight connection and help limit the position.
