Abstract

The utility model discloses a kind of shovel drag hook shrinking operation for posterior scleral, including handle, axial shape is the arcuation of bending, and section configuration is round or oval；Gib head, itself and the handle integrally connected, the shape of the gib head is the flat elongate body of S-shaped bending, and the gib head is the first bending section close to the side of the handle, first bending section is identical as the bending direction of the handle, side of the gib head far from the handle is the second bending section, and second bending section is opposite with the bending direction of the handle.The utility model; it can fully expose and protect eyeball rear portion sclera; fixation can be walked and sutured after ball for band, and facility is provided; the special designing of handle angle; it can avoid overhanging the micro- lens head of top; and reduce assistant and hold interference by operator, for the operating space for smoothly implementing to provide bigger of performing the operation, operation work efficiency and the safety is improved.

Description

A kind of shovel drag hook shrinking operation for posterior scleral

Technical field

The utility model is related to ophthalmic instruments, and in particular to a kind of shovel drag hook shrinking operation for posterior scleral.

Background technology

Posterior scleral shrinks effect of the operation in terms of control high myopia disease progression prevention and treatment eyeground pathological changes at present, Increasingly paid attention to by clinical ophthalmology.

But posterior scleral shrinks operation and carries out less, art formula not yet specification and uniformly in clinic, and there are no suitable surgical devices Tool affects the therapeutic effect of the operation and is further promoted and applied in clinic for special.

The operation for implementing the operation relates generally to eyeball rear portion sclera, due to the special anatomical structure of eye, after eyeball It portion's narrow space and is difficult to expose, and high myopic eye axis oculi is elongated, eyeball becomes larger, the expansion of posterior scleral lesion, and tissue becomes crisp fritter It is weak, there is staphyloma to be formed, surgical procedure can be made more difficult, organizes separation after eyeball drawing and ball, easily cause extraocular muscle Meat damages and the risk of eyeball rupture.

Unresolved posterior scleral shrinks the needs of expansion, designs a kind of special equipment of posterior scleral contraction operation, can deviate Micro- lens head is walked and is sutured fixation after ball for band and provide facility, can avoid the micro- lens head for overhanging top, And reduce assistant and hold interference by operator, implement the operating space that bigger is provided for operation, operation work efficiency and the safety is improved.

Utility model content

Technical problem to be solved in the utility model is the special equipment for lacking posterior scleral currently on the market and shrinking operation The problem of.

In order to solve the above-mentioned technical problem, technical solution used by the utility model is to provide a kind of for posterior scleral receipts The shovel drag hook for art of drawing back one's hand, including：

Handle, axial shape are the arcuation of bending, and section configuration is round or oval；

Gib head, and the handle integrally connected, the shape of the gib head are the flat elongate body of S-shaped bending, and institute It is the first bending section that gib head, which is stated, close to the side of the handle, and first bending section is identical as the bending direction of the handle, Side of the gib head far from the handle is the second bending section, the bending direction phase of second bending section and the handle Instead.

In the above scheme, the width of first bending section is become narrow gradually by both ends to centre.

In the above scheme, the both sides of first bending section are in the V-arrangement to concave.

In the above scheme, the curvature of the one end of second bending section far from first bending section is less than described second The curvature of one end of first bending section is closed in bending section.

In the above scheme, the handle is equipped with anti-skid chequer.

In the above scheme, the length of the handle is 60 millimeters.

In the above scheme, the length of first bending section is 20 millimeters, and the length of second bending section is 30 millis Rice.

The utility model can fully expose and protect eyeball rear portion sclera, can walk and suture after ball for band Fixed to provide facility, the special designing of handle angle can deviate micro- lens head, and reduce assistant and hold by being done to operator It disturbs, smoothly implements to be capable of providing the operating space of bigger to perform the operation, operation work efficiency and the safety is improved.

Description of the drawings

Fig. 1 is the appearance schematic diagram of the utility model；

Fig. 2 is the structural schematic diagram of gib head in the utility model.

Specific implementation mode

The utility model is described in detail with reference to the accompanying drawings of the specification.

As depicted in figs. 1 and 2, a kind of shovel drag hook shrinking operation for posterior scleral provided by the utility model, including： Handle 1 and gib head 2, the wherein axial shape of handle 1 are the arcuation of bending, and the section configuration of handle 1 is round or oval；Hook First 2 with 1 integrally connected of handle, the shape of gib head 2 be the flat elongate body of S-shaped bending, and gib head 2 is close to the side of handle 1 First bending section 21, the first bending section 21 is identical as the bending direction of handle 1, and side of the gib head 2 far from handle 1 is the second bending Portion 22, the second bending section 22 are opposite with the bending direction of handle 1.The width of first bending section 21 is gradually become by both ends to intermediate It is narrow, and the both sides of the first bending section 21 are in the V-arrangement to concave, and it is empty can to expand operation when using pulling for such design Between, the visual area smaller blocked such as detects convenient for operative doctor, sutures at the operations.

When the utility model is used, it pulls open exposure using gib head 2 and assists separation ball week, detect posterior scleral.Instrument is in Miniaturization, adapts to the requirement of micrurgy.

It is further preferred that handle 1 is equipped with anti-skid chequer, stability when use and safety are enhanced.

The length of handle 1 is 60 millimeters.The length of first bending section 21 is 20 millimeters, and the length of the second bending section 22 is 30 Millimeter, to adapt to micrurgy size requirements.

The utility model can fully expose and protect eyeball rear portion sclera, can walk and suture after ball for band Fixed to provide facility, the special designing of handle angle can avoid the micro- lens head for overhanging top, and reduce assistant and hold By the interference to operator, for the operating space for smoothly implementing to be capable of providing bigger of performing the operation, operation work efficiency and the safety is improved.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn that under the enlightenment of the utility model The structure change made, it is every that there is same or similar technical solution with the utility model, each fall within the guarantor of the utility model Within the scope of shield.
