Description

Posterior scleral shrinks long forceps after operation ball

Technical field

The utility model relates to ophthalmic instruments, and in particular to posterior scleral shrinks long forceps after operation ball.

Background technique

Effect of the posterior scleral Narrowing in terms of control high myopia disease progression prevents and treats eyeground pathological changes, increasingly Attention by clinical ophthalmology.The operation for implementing the operation relates generally to eyeball rear portion sclera, since there are extraocular muscle, whirlpool in eye rear portion Vein, the vital tissues such as optic nerve, anatomical structure is complicated, is limited by eye socket, narrow space, it is difficult to exposure, and high myopia Eye axis oculi is elongated, and eyeball becomes larger, and the expansion of posterior scleral lesion organizes thinning fragility, has staphyloma to be formed, operates more difficult, eye Separation is organized after ball drawing and ball, easily causes the risk of extraocular muscle meat damage and eyeball rupture.But current scleral reinforcement hand Art carries out less, art formula not yet specification and uniformly in clinic, and there are no suitable surgical instruments for dedicated, affects the operation Therapeutic effect and clinic further promote and apply.

Shrink strip band is placed on suitable position and sutures the committed step that fixation is the operation, and in surgical procedure, band is needed It to be bypassed behind eyeball, wrap posterior pole of eyeball portion and staphyloma area, due to eyeball rear face locating depth, the space that can be exposed is narrow It is small, it can only be walked depending under blind, the temporo side of band is easy to be wrapped up fan hiding by inferior oblique muscle abdomen, and is difficult to be removed, and influences hand Art process and there is the risk for causing postoperative complication.

It can be seen that current band placement has that operation precision is low, influences procedure.

Utility model content

Technical problem to be solved in the utility model be current band to place that there are operation precisions low, influence to perform the operation into The problem of journey.

In order to solve the above-mentioned technical problem, technical solution used by the utility model shrinks there is provided posterior scleral and performs the operation With long forceps after ball, including integrally formed fixed part, grip part and clamping end, the end of the clamping end is equipped with drag hook, described In the same plane, the length of the drag hook is 1~2mm for drag hook, the clamping end and grip part setting.

In another preferred embodiment, the angle between the drag hook and the clamping end is 90 °.

In another preferred embodiment, the clamping end is connected by long-armed with the grip part, the clamping end With the long-armed formation obtuse angle.

In another preferred embodiment, the grip part is in thick shape between the detail of both ends, the grip part it is outer Side is equipped with the first anti-skid chequer.

In another preferred embodiment, the clamping end and described hook take that second is respectively equipped on the opposite face at end is anti- Sliding line.

In another preferred embodiment, the width of the clamping end is greater than the long-armed width.

The utility model, for taking out band temporo side, the design of drag hook increases clamping range and clamping flexibility ratio, folder After holding end closure overturning, drag hook can pull separated inferior oblique muscle, be easy exposure and take out the band that fan ensconces under inferior oblique muscle belly of muscle Temporo side can accelerate procedure, improve operation safety.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model provides posterior scleral and shrinks long forceps after operation ball, and for taking out band temporo side, drag hook is set Meter increases clamping range and clamping flexibility ratio, and after clamping end is closed, separated inferior oblique muscle can be pulled by mediating overturning, exposed and suitable Benefit takes out the band head end that fan ensconces under inferior oblique muscle belly of muscle using drag hook, can accelerate procedure, improve operation safety.

The utility model is described in detail with Figure of description combined with specific embodiments below.

As shown in Figure 1, long forceps includes integrally formed fixation after posterior scleral provided by the utility model shrinks operation ball The end of portion 11, grip part 12 and clamping end 131, clamping end 131 is equipped with drag hook 132, drag hook 132, clamping end 131 and grip part In the same plane, the length of drag hook 132 is 1~2mm for 12 settings.The length of drag hook 132 is 2~5mm, and such structure is neither It will affect the holding action in operation, hook can also be facilitated to take movement, holding action and hook take movement that can reach coordination and flexible.

The utility model is used to shrink in operation in posterior scleral, takes out band temporo side.Two clamping ends 131 are closed, After mediating overturning, drag hook 132 can pull separated inferior oblique muscle, and exposure simultaneously takes out the band head end that fan ensconces under inferior oblique muscle belly of muscle, Procedure is accelerated, and the safety is improved.

Angle between drag hook 132 and clamping end 131 is 90 °, this angular range can reduce by 132 pairs of drag hook operations as far as possible The influence of movement.

Clamping end 131 connects by long-armed 130 with grip part 12, and clamping end 131 and long-armed 130 forms obtuse angle, can reduce Operative site visual area is blocked in operating process, increases the open degree of visual area.

Grip part 12 is equipped with the first anti-skid chequer 121 in shape thick between the detail of both ends, the lateral surface of grip part 12, and both ends are thin Centre can slightly reduce the influence to visual area to greatest extent, and frictional force can be improved in anti-skid chequer, prevent from holding and take slippage.

It is respectively equipped with the second anti-skid chequer on the opposite face of two clamping ends 131, clamping is made to be not easy to slip.The width of clamping end 131 Degree is greater than long-armed 130 width, increases clamping face, and then improve chucking power.

The utility model, for taking out band temporo side, the design of drag hook increases clamping range and clamping flexibility ratio, folder After holding end closure overturning, drag hook can pull separated inferior oblique muscle, and exposure simultaneously takes out the band temporo side that fan ensconces under inferior oblique muscle belly of muscle End, can accelerate procedure, improve operation safety.

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 all 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.
