Description

A kind of toy vertebral plate stings pincers

Technical field

This utility model relates to a kind of toy vertebral plate and stings pincers.

Background technology

Spinal cord injury is many to be caused caused by spinal fracture, dislocation because traffic accident, the high-energy impact such as to fall cause, and often causes the following limbs disturbance of damage sections, causes permanent disability further.And along with the fast development of traffic, building and mining industry, and the outburst of natural disaster and war, spinal cord injury is in ascendant trend year by year.According to spinal cord injury prevention and health care control foundation statistics, China has 2,000,000 Patients of Spinals at least, the patient of 1% is only had to recover completely, Most patients's only legacy part function or paralyse completely, and 82% is male adults in these patients, not only can bring on health and psychological grievous injury to sufferers themselves, also can cause huge economy and mental burden to whole family and society.Therefore, how successfully to repair spinal cord injury and remain a global problem and study hotspot at present.

Toy, as mice, it is fast that rat etc. have breeding, produces son many, energetic, and being easy to control and the quality standard advantage such as clearly, is the most frequently used animal model of current spinal cord injury research.But because its toy is small, spinal column skeletal structure is also less, remove the bony structures such as vertebral plate very difficult in very little visual area boundary, this proposes greatly to challenge to the requirement of the technology of patient and apparatus.There is no the rongeur tool being applicable to toy spinal operation of specialty at present, and the apparatus master being applied to the bone structures such as removal toy vertebral plate has common rongeur, eye scissors and dental burr etc., inefficiency, the structures such as easy damaged spinal cord, spinal dura mater and nerve, make the efficiency of setting up of spinal cord injury study model have a greatly reduced quality.So there is no the rongeur tool being applicable to toy of a specialty, the research difficulty of spinal cord injury is strengthened further, the success rate that spinal cord injury model is set up reduces greatly, and inappropriate operating theater instruments can make the credibility of experimental result and repeatable reduction to the isostructural non-specific damage of spinal cord simultaneously.

Utility model content

The purpose of this utility model is the deficiency that above-mentioned background technology exists, and provides a kind of toy vertebral plate to sting pincers.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of toy vertebral plate stings pincers, comprise two by the hinged tong arm of rotating shaft, connect the reseting spring leaf of two tong arms, described tong arm comprises handle and binding clip, handle and binding clip are integral type structure, its special character is: the binding clip of described tong arm has the first jaw, in the second jaw of the first jaw back lower place and the sword face between the first jaw and the second jaw, described binding clip is reclinate structure from rear end to front end, described two binding clips have arc-shaped concave in opposite directions simultaneously, the tip angle α of described first jaw is 60 °, the tip angle β of the second jaw is 120 °.

Further, the sword face length degree of described binding clip is 2-5mm, and sword face length degree is preferably 2mm.

The toy vertebral plate that this utility model provides stings pincers, compact conformation, compact, be suitable for the operation of toy spinal operation, in art, toy vertebral plate is stung pincers and can be reduced neural, spinal dura mater and the isostructural damage of spinal cord, accelerate the cutting speed rate of stinging of the bone structures such as vertebral plate, effectively improve efficiency and the success rate of spinal cord injury model foundation.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Wherein, 1, rotating shaft, 2, reseting spring leaf, 3, handle, 4, binding clip, 4-1, the first jaw, 4-2, the second jaw, 4-3, sword face, 5, arc-shaped concave.

Detailed description of the invention

Below in conjunction with drawings and the specific embodiments, this utility model is described in detail.

See Fig. 1 and Fig. 2, the toy vertebral plate of this utility model embodiment stings pincers, comprise two by the hinged tong arm of rotating shaft 1, connect the reseting spring leaf 2 of two tong arms, tong arm comprises handle 3 and binding clip 4, handle 3 and binding clip 4 are integral type structure, the binding clip 4 of tong arm has the first jaw 4-1, at the second jaw 4-2 of the first jaw 4-1 back lower place and the sword face 4-3 between the first jaw 4-1 and the second jaw 4-2, binding clip 4 is reclinate structure from rear end to front end, two binding clips 4 have arc-shaped concave 5 in opposite directions simultaneously, when two binding clips are combined, two take the lead between there is vacant place, operation sight line is better, the tip angle α of the first jaw 4-1 is 60 °, the tip angle β of the second jaw 4-2 is 120 °, the sword face 4-3 length of binding clip 4 is 2-5mm, sword face 4-3 length is preferably 2mm.

The toy vertebral plate of this utility model embodiment stings pincers, by carrying out Curve guide impeller to tong head, binding clip has the first jaw, the second jaw and sword face therebetween, and the tip angle of feature to the first jaw, the second jaw being combined in the operation of toy spinal operation designs, the curved design of two binding clips and the design of arc-shaped concave simultaneously, meet the feature of toy spinal operation, in successful, the efficient foundation of spinal cord injury model, there is good using value, to the research of spinal cord injury, there is good facilitation.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
