Description

Miniatrue nickelclad fixator for jaw fracture
This utility model belongs to the improvement of the miniature steel plate holder (comprising miniature blade plate, miniature screw thread, general utility tool and specific purpose tool) used of treatment maxillofacial fracture.
The miniature steel plate holder that the treatment maxillofacial fracture is used is made up of miniature blade plate, miniature screw thread, general utility tool and specific purpose tool, and it is the important utensil of treatment maxillofacial fracture.Use this utensil can shorten operating time, reduce the painful and raising therapeutic effect of patient.Before this utility model development, domestic do not have a this product.Though this product is abroad arranged, because foreign trader's profit-push is mixed this special-purpose assorted utensil with a large amount of general utility tools, therefore bring a high price, it is domestic that nobody buys so far.For example, the titanium series holder that U.S. Walter lorenz operating theater instruments company produces, every cover price is up to 7717 dollars, and a screw is worth 8~9 dollars.The utensil of this costliness, imitated after clinic trial, finding has following deficiency: the size of (1) miniature blade plate is not suitable for the size of Asians's jawbone; (2) kind of miniature blade plate (by the shape branch) can not satisfy the treatment requirement of Asians's jaw fracture; (3) thread profile of miniature screw thread is rectangle and equilateral triangle, does not meet the big medical requirement that is screwed into that resistance is little, tension is exerted oneself; (4) specific purpose tool of clamping miniature screw thread is a three-jaw chuck, and clamping is unreliable, and screw often drops out, influence operation quality and prolongation operating time; (5), do not guarantee the specific purpose tool of perpendicularity between screw and the surface of bone to lower jaw bight and ascending branch portion fracture patient.
The purpose of this utility model is that design one cover is suitable for the miniature blade plate that Asians's maxillofacial fracture uses, and miniature screw thread in state's external fixator and specific purpose tool are made improvements.
Major technique of the present utility model thes contents are as follows: (1) designs the miniature blade plate of 11 kinds of difformities and size by a large amount of on-site inspections and statistics, selects for use for the east patient is clinical; (2) design a kind of new screw thread section, it is little to make it be screwed into resistance, and tension is exerted oneself greatly, to meet medical requirement; (3) a kind of new full dog point socket set cutter of design turns miniature screw thread during for the loading and unloading blade plate and uses; (4) a kind of soft tissue of design tunnel mirror is to guarantee the perpendicularity between miniature screw thread and lower jaw bight and the ascending branch surface of bone.
This utility model compares with similar external product, and have the following advantages: (1) has improved the suitability of miniature blade plate; (2) She Ji specific purpose tool makes operation more convenient reliable, and has shortened operating time; (3) improvement of miniature screw thread thread profile makes this screw be more suitable for medical requirement, thereby has improved quality of medical care; (4) cheap, 520 yuan of the every prices of this utility model only are one of seventy points of Walter company sale price, have created advantage for generally promoting the use of.
