Description

Technical Field

[0001] The utility model belongs to the technical field of bone extraction tools, in particular to a bone extraction tool for gum implantation block bones. Background Art

[0002] Dental implants are becoming more and more common. Many patients do not have dental implants for a long time after their teeth fell out, resulting in insufficient bone mass in the bone socket. Theoretically, dental implants cannot be performed if the bone mass is insufficient, because there is not enough bone to support the implant. If forced implant restoration is performed, it will cause great harm to the body, so bone implantation is required first.

[0003] Currently, cylindrical bones are removed by tools such as positioning drills, bone column drills and bone prying machines, while block bones are removed by slightly different tools. The bone column drill is replaced by an osteotome, and a block of bone of appropriate size is chiseled out by the osteotome. The bone root is then pried off with a bone pry and removed with a bone clamp. However, the bone is pried off by a bone prying machine using the principle of leverage, and the fracture cross-section is relatively rough, making subsequent processing more difficult.

[0004] Therefore, it is very necessary to invent a bone-taking tool for gum implant block bone. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a bone removal tool for gum implant block bone, comprising a bone root twisting head and a torque handle, wherein the bone root twisting head ferrule is fixed below one end of the torque handle, and the bone root twisting head is a rectangular structure as a whole;

[0006] The bone root twisting head comprises a twisting sleeve, a recessed groove, a spring pick, a disinfection hole, a clamp and a clamping groove. Four recessed grooves are provided on the inner surface of the twisting sleeve, a spring pick is fixedly installed in the recessed groove provided on the twisting sleeve, four disinfection holes are provided on the twisting sleeve, a clamp is fixedly installed above the twisting sleeve, four clamping grooves are provided on the clamp, and the clamping sleeve is fixed on the torque handle;

[0007] The torque handle comprises a handle rod, a handle head, a ferrule head and a ball pin. The handle head is fixedly mounted on one end of the handle rod, the ferrule head is fixedly mounted below the handle head, a ball pin is elastically and slidably mounted inside the ferrule head, and the ferrule head fixes the ferrule head through the ball pin and in cooperation with the card slot.

[0008] Preferably, the twist-off sleeve is a rectangular sleeve, an inclined surface is provided below the twist-off sleeve, and the recessed groove provided inside the twist-off sleeve is a trapezoidal recessed groove, which is communicated with the disinfection hole.

[0009] Preferably, a plurality of spring paddles are arranged inside the recessed groove, and the spring paddles are arc-shaped structures, and there are intervals between the spring paddles inside the recessed groove.

[0010] Preferably, the clamping head is a rectangular head, the clamping head is adapted to the ferrule head, the clamping groove provided in the clamping head is adapted to the ball pin, and the ball pin is a semicircular ball head.

[0011] Preferably, a groove required for ball pin installation is provided inside the ferrule head, and the groove is elastically slidably connected to the ball pin via a spring, and the groove allows the ball pin and the spring to be contracted inside.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model is different from the traditional technology of prying bones through the lever principle. The utility model is arranged on the outside of the block bone and applies torque force to it, so as to fracture the bone through the rotational force. The fracture surface of the bone root is relatively smooth, and the subsequent treatment is more convenient. Secondly, the lever arm principle in the lever principle is used to increase the torque, so that the operation is more labor-saving. In addition, the bone root twisting head and the torque handle can be quickly disassembled, so that it is convenient to replace the bone root twisting heads of different sizes. At the same time, the broken block bone can be directly taken out later, and there is no need to use bone forceps to take out the bone. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1:

[0026] Specifically, the twist-off sleeve 11 is a rectangular sleeve, and an inclined surface is arranged at the bottom of the twist-off sleeve 11. The recessed groove 12 opened inside the twist-off sleeve 11 is a trapezoidal recessed groove, and the recessed groove 12 is communicated with the disinfection hole 14. After the block bone is taken out, the medical staff will soak the used bone root twist-off head 1 in the disinfectant, and the disinfectant will quickly enter the interior through the disinfection hole 14 to disinfect it. In addition, the disinfection hole 14 can also play a role in discharging blood foam.

[0027] Specifically, a plurality of spring paddles 13 are arranged inside the recessed groove 12. The spring paddles 13 are arc-shaped structures. There are intervals between the spring paddles 13 inside the recessed groove 12. The spring paddles 13 protrude outwards. The spring paddles 13 are used to clamp the block bone.

[0028] Specifically, the chuck 15 is a rectangular head, which is matched with the ferrule head 23 . The slot 16 provided on the chuck 15 is matched with the ball pin 24 . The ball pin 24 is a semicircular ball head, and the ball pin 24 is designed for quickly replacing the torque handle 2 .

[0029] Specifically, a groove required for installing the ball pin 24 is opened inside the ferrule head 23, and the groove is elastically slidably connected to the ball pin 24 through a spring, and the groove allows the ball pin 24 and the spring to be contracted inside.

[0030] Embodiment 2: When it is necessary to remove the block bone, the bone root twisting head 1 of the appropriate block bone size is installed on the torque handle 2, and the clamping head 15 of the bone root twisting head 1 is inserted into the ferrule head 23 of the torque handle 2. At this time, the ball pin 24 inside the ferrule head 23 uses the spring elastic force and cooperates with the card slot 16 to fix the clamping head 15 in the ferrule head 23, and then the installation is completed. Subsequently, the twisting sleeve 11 is placed on the outside of the block bone. During this process, the spring paddle 13 inside the twisting sleeve 11 is deformed after contacting the block bone, and the block bone is firmly clamped. Then the medical staff applies torque to it through the torque handle 2, and the torque handle 2 twists the block bone through the bone root twisting head 1. After twisting it off, the block bone can be directly taken out, and its fracture surface is subsequently polished.
