Novel forceps for reduction of sagittal fracture of mandibular condyle and production method of jaws of novel forceps

Abstract

The invention discloses novel forceps for the reduction of sagittal fracture of mandibular condyle; the novel forceps comprise two handheld rings and two connection parts; the two connection parts are hinged to each other; two forceps arms are arranged at the upper end; the top end of one forceps arm is provided with a positioning jaw, and the top end of the other forceps arm is provided with a fastening jaw; the positioning jaw comprises two clamp tips that connect at the base and open at the end; the fastening jaw is releasably inserted between the two clamp tips. The novel forceps are suitable for the reduction of a fracture between the upper end face of the mandibular condyloid process and the two clamp tips, is widely applicable, and is good in flexibility. A production of jaws of the novel forceps for the reduction of sagittal fracture of mandibular condyle is also disclosed; the jaws are made by combining: ultrahigh molecular weight polyethylene, nano ZnO, nano chitosan and the sintering aid nano Ni; the production method of the jaws has low production cost, the jaws gain well-improved tensile strength, impact resistance, rigidity and hardness, the antibacterial capacity is also greatly improved, and the jaws are applicable as disposable jaws.

Description

technical field [0001] The invention relates to a medical device, in particular to a novel condylar sagittal fracture reduction and fixation forceps and a preparation method thereof. Background technique [0002] The incidence of sagittal condylar fractures accounts for about 9% to 45% of mandibular fractures. Its treatment has always been the focus and difficulty of oral and maxillofacial trauma. If not treated properly, it is easy to cause traumatic arthritis, ankylosis and other related complications disease. During the surgical treatment of sagittal condylar fractures, the displaced fractures must be reduced before being fixed. The quality of reduction is the key to treatment. Reduction and fixation forceps are often used in surgery to reset the discrete bones at the fracture site or to maintain the reset bones. Only after the bones at the fracture site are reset and firmly clamped can the follow-up surgery work be performed. The head structure of the reduction forceps...

Problems solved by technology

However, the hole in the middle of the contact between the two clamp heads is used to fix the sagittal condyle. The fixation effect is poor, and it is only suitable for the fracture of the upper sagittal condyle. The scope of use is limited and the flexibility is poor; Even if the forceps are sterilized after use, there are still health and safety hazards. The body of the surgical forceps is generally made of high-carbon steel. The production process of this material is complicated and the cost is high. The cost of discarding the surgical forceps or the surgical forceps head after use is too high , so there is an urgent need for a surgical forceps head made of a new type of medical material with low cost to realize the purpose of one-time use of the forceps head and postoperative replacement
