Description

Visual manual angle torque wrench and device for oral titanium mesh bone grafting

Technical Field

The application relates to the field of medical equipment, in particular to a visual manual angle torque wrench and a device for oral titanium mesh bone grafting.

Background

In the field of implantology, partial patients have insufficient local residual bone due to disuse or pathological factors, do not meet basic conditions for implantation or cannot obtain good initial stability of the implant, and then bone augmentation surgery is needed to solve the problem of insufficient bone in the area. The guided bone regeneration technique for the purpose of reconstructing bone tissue is called "guided bone regeneration" (GBR). The proposal of the guided bone regeneration theory and the maturity of the technology provide a reliable technical guarantee for solving the problem of insufficient bone mass for planting. The definition is that at the bone defect, a biological barrier membrane is utilized to maintain the space established by the operation, and thereby epithelial cells and fibroblasts which proliferate fast are prevented from growing in, and the growth of osteoblasts and blood vessels which proliferate at slow speed is ensured. However, the materials conventionally used as barrier membranes (e.g., absorbable collagen membrane, non-absorbable PTFE membrane) lack self-forming ability, are difficult to maintain a stable space, may collapse after surgery, interfere with bone regeneration in the surgical field, and even cause surgical failure due to infection caused by exposure of the barrier membrane. The traditional GBR and onlay bone grafting technology cannot perfectly realize the reappearance of the three-dimensional bone wall, at the moment, the titanium nail and the titanium mesh play unique advantages in the application of guided bone regeneration, the good mechanicalness of the titanium nail and the titanium mesh can provide supportive protection for bone regeneration, and the bone supply quantity required by autologous bone grafting is reduced. Compared with the traditional barrier film, the titanium mesh has certain strength, can guide and control the contour and the shape of the regenerated bone, and keeps the relative stability of the space; the titanium net has smooth surface, bacteria are not easy to attach, and the infection risk can be reduced.

On the basis of imaging examination such as CT before an operation, preforming is carried out according to the shape and the size of bone defect in an operation area in the traditional titanium mesh bone grafting, and a titanium nail is utilized to fix the titanium mesh on a bone-defect-free jaw bone adjacent to the bone defect in the operation so as to provide a bone forming space for bone regeneration. However, the traditional titanium mesh bone grafting technology has the defects of dead zone on the lingual side, unclear visual field, difficult retention, more vessels on the lingual side, higher operation difficulty, larger range of flap-turning operation in the operation and more serious postoperative swelling of a patient; when the bone defect area is close to the adjacent tooth, the titanium mesh fixation operation may risk damaging the root of the adjacent tooth. The operation space of the oral lingual side or the palatal side is limited, and the like.

The labial retention is still feasible when the titanium nail is fixed by a hand instrument, but when the titanium net is fixed by the jaw-side or lingual-side titanium nail, the angle of the hand instrument is inconvenient because the hand instrument is too long, the fixing position is too low (for example, the fixing position is too deep from the crest of the alveolar ridge relative to the crest of the alveolar ridge), or the adjacent tooth is blocked, so that the lingual-side titanium net is difficult to be clinically fixed.
