Problems solved by technology

The hemostat is a device used to clamp blood vessels. It is not easy to control the clamping force when using the hemostat to remove the autologous bone tissue. If the clamping force is too large, the edge of the autologous bone may be broken, and the broken edge will cause bone grafting. Local inflammatory response during bone remodeling; if the clamping force is too small, it may cause the autologous bone tissue to slip, resulting in bone tissue contamination, which violates the principle of aseptic operation
Ordinary tweezers can be used to hold instruments and objects for oral operations, but since the autologous bone tissue is extremely precious, it is easy to fall into the patient's mouth or even the ground due to a little carelessness during the operation, resulting in the failure of the operation
[0004] Therefore, the use of existing instruments for oral autologous bone transplantation has high technical sensitivity, and the instruments are too independent. They are only used in autologous bone transplantation when necessary, and are not supporting tools designed for bone transplantation. easy to fail

Embodiment 1

[0047] Such as Figure 1-8 As shown, a group of bone grafting instruments, including bone tissue separator 1, after the bone tissue in the operation area is cut, the surface of the cortical bone is cut, and the cancellous bone on the deep inner surface is still connected, and the bone tissue in the donor area needs to be separated. The bone tissue separator 1 includes a first bone tissue separator 1a, a second bone tissue separator 1b and a third bone tissue separator 1c.

[0048] The bone tissue separator 1 includes a rod-shaped handle 1.1, a connecting rod 1.2, and a cutter head 1.3, and the total length is about 185mm, that is, the first bone tissue separator 1a, the second bone tissue separator 1b and the third bone tissue separator 1c are all 185mm, the rod-shaped handle 1.1 and the connecting rod 1.2 are located on the same axis, and the two ends of the connecting rod 1.2 are respectively connected to the front end of the handle 1.1 and the rear end of the cutter head 1....

Embodiment 2

[0052] Such as Figure 1-5 , as shown in 9-14, the structure described in embodiment 2 is basically the same as that of embodiment 1, the difference is that the clamping piece 2.3.2 of the bone tissue extractor is provided with a stopper 2.3.4 outside, and the clamping piece The thickness of 2.3.2 and blocking piece 2.3.4 is less than 1 cmm. There is an interlayer cavity between the clamping piece 2.3.2 and the blocking piece 2.3.4, and a filling piece 2.3.5 is arranged in the interlayer cavity. The interlayer cavity is provided with a cavity opening 2.3.6, and the cavity opening 2.3.6 faces the direction of the splint 2.3.1, which is convenient for taking and placing the filling piece 2.3.5, and the filling piece 2.3.5 will not fall into the oral cavity. Filling sheet 2.3.5 is one of absorbent cotton sheets, water-swellable cross-linked polymer sheets, and silica gel sheets. The dry hemostatic agent is adsorbed on the filling sheet 2.3.5. Filler 2.3.5 can be soaked in liqui...

Abstract

The invention discloses a group of bone grafting instruments, including a bone tissue separator, including a rod-shaped handle, a connecting rod, and a cutter head. There are side blades on both sides of the blade surface; it includes a bone tissue extractor, which is in the shape of pliers. The pliers head is composed of two splints. The top of the two splints is respectively equipped with a clamping structure with a sandwich. Material. It also includes a bone tissue holder, which is in the shape of tweezers. The tops of the tweezer arms are respectively provided with "C"-shaped tweezers heads; The unique structure of the instruments of the present invention and the mutual cooperation between the instruments can reduce the technical sensitivity in the process of separating, taking out and holding the oral autogenous bone, increase the success rate of the operation, reduce the difficulty of the doctor's operation, and reduce the Painful, conducive to the prognosis of surgery.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a group of bone grafting devices. Background technique [0002] Oral implant restoration is one of the most common ways to restore missing teeth in the mouth. Dental implant surgery often requires bone graft surgery due to insufficient bone in the tooth-missing area. Autologous bone is the ideal material for bone grafting, and block bone grafting is a common method of intraoral autologous bone grafting. [0003] At present, due to the lack of suitable instruments, some traditional instruments used in oral tooth extraction are often used for autologous bone transplantation, such as tooth lifts for separating bone tissue, hemostats for removing bone tissue, and ordinary tweezers for holding bone tissue. However, the instrument greatly increases the technical sensitivity during operation, which may easily lead to contamination and even failure of bone extraction. For example, a dent...
