Description

A lens capsule polisher

technical field

The utility model relates to an ophthalmic medical instrument, in particular to a lens capsule polisher.

Background technique

In cataract surgery, after continuous circular capsulorhexis, removal of turbid material in the capsular bag, and implantation of intraocular lenses, most physicians do not deal with the remaining peripheral lens anterior capsule because there is no suitable instrument for anterior capsule polishing . As a result of not polishing the anterior capsule, some patients will need further laser or even surgical treatment due to capsular contraction syndrome, and some patients will develop post-cataract, which also requires laser or even surgical treatment. Some patients need examination or treatment due to fundus diseases, but the examination or treatment of the fundus is affected by the opacity or shrinkage of the surrounding capsule, resulting in delays in treatment. Due to structural limitations, the existing lens capsule polishers generally require mirror-symmetrical left-handed and right-handed models, and can only polish a limited area. When using the existing lens capsule polisher for cataract surgery, a left-handed and a right-handed polisher are required to be inserted through the main incision to polish the left lower side and the right lower side of the anterior lens capsule respectively. Even with two polishers, polishing of the anterior capsule at the main incision was not possible. Therefore, based on the performance of the existing instruments, the hospital needs to spend more money to purchase two different instruments for each cataract operation. During the operation, the two instruments need to be replaced for polishing, which not only increases the operation time, but also increases the risk of infection , which is one of the main reasons why physicians do not polish the anterior capsule.

Utility model content

The existing lens capsule polisher has a limited treatment area, and each operation requires two instruments to operate from different directions, resulting in an increase in equipment purchase costs. In order to overcome this defect, the utility model provides a polishing range that can be used The inside of the capsular bag is fully treated, so as to improve the operation efficiency, reduce the amount of equipment, and save the cost of equipment purchase.

The technical solution of the utility model is: a lens capsule polisher, including a handle and an extension rod, a polishing head is fixed on the extension rod, the polishing head is flat as a whole, and the width is greater than the diameter of the rod body of the extension rod. There are front and side forwards. Since the widest part of the front end is not greater than 1mm, it can be operated through a 1mm side incision to achieve capsular bag polishing at the main incision. At the same time, because the side edge of the polishing head is thin and smooth, the anterior capsule is scraped upward with the side edge to achieve high-efficiency polishing. During the operation, only one instrument needs to be inserted into the eye from the side incision and the main incision, and the 360° anterior capsule in the capsular bag can be polished, which greatly improves the operation efficiency, reduces the amount of surgical instruments, and saves the purchase cost. In addition, the front end can also polish the equator of the capsular bag to reduce the incidence of post-cataract, which has always been the culprit of visual impairment after cataract surgery.

Preferably, the width gradually decreases from the free end of the polishing head to the fixed end of the polishing head, and the width of the widest part of the polishing head is 0.9-1 mm. The front end of the polishing head is wide and the rear end is narrow, which conforms to the mechanical characteristics of the anterior capsule polishing with the incision as the fulcrum. The polishing effect is good, the scope is large, and the speed is fast.

Preferably, a smooth transition arc is provided at the ends of the front end and the side edge, and at the junction of the front edge and the edge edge. Setting a smooth transition arc can eliminate sharp parts on the polishing head, avoid trauma to the capsule, and reduce the risk of accidental injury.

Preferably, the extension rod is provided with a V-shaped bend with a bending angle of 148°-152°. The extension rod is set with a moderate V-shaped bend, which not only helps to provide a good view for the surgeon during the operation, but also does not affect the control of the operation force.

Preferably, the handle is provided with anti-skid lines. The anti-slip pattern is provided to facilitate the doctor to hold the instrument stably during the operation and prevent accidental slipping.

The beneficial effects of the utility model are:

The polishing range is large, the work efficiency is high, and the lesions are completely eliminated. When the utility model is used for cataract surgery, 360° no-dead-angle and no-residue capsule polishing can be realized with one instrument, which solves the problem of capsular bag shrinkage after cataract surgery and reduces the complications of post-cataract surgery At the same time, the anterior capsule remains transparent after operation, which is convenient for fundus examination after operation.

Save equipment purchase cost. Because the utility model has a large polishing range, only one instrument can replace two instruments in the prior art, thereby reducing half of the instrument purchase cost.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model.

In the figure, 1-handle, 2-extension rod, 3-polishing head, 4-front front, 5-side front, 6-anti-skid pattern.

detailed description

The utility model will be further described below in conjunction with the specific embodiments of the accompanying drawings.

Example 1:

As shown in Figure 1, a lens capsule polisher includes a handle 1 and an extension rod 2, the handle 1 is provided with anti-skid lines 6, the extension rod is fixed with a polishing head 3, and the polishing head 3 is flat as a whole, and The width is greater than the diameter of the rod body of the extension rod 2 , and the polishing head 3 is provided with a front edge 4 and a side edge 5 . From the free end of the polishing head 3 to the fixed end of the polishing head 3, the width gradually decreases, and the widest part of the polishing head 3 is 1mm. The ends of the front end 4 and the side front 5 and the junction of the front end 4 and the side front 5 are all provided with smooth transition arcs. The extension rod 2 is provided with a V-shaped bend with a bending angle of 150°.

When the main incision and the side incision are separated by one quadrant or more, this capsule polisher can be used to polish the inferior, nasal and temporal anterior capsule through the main incision, and to polish the anterior capsule on the contralateral or superior incision through the side incision The film is polished. The polishing head 3 can smoothly enter the capsular bag through the main incision and the side incision, and use the front edge 4 and the side edge 5 to efficiently scrape the epithelial cells of the capsule without damaging the capsule by swinging or rotating; length, even deep into the equator of the pouch for polishing.

Example 2:

The bending angle of the extension rod 2 V-shaped bending is 148°, and the widest part of the polishing head 3 is 0.9mm. All the other are with embodiment 1.

Example 3:

The bending angle of the 2V-shaped bending of the extension rod is 152°, and the rest are the same as in Embodiment 1.
