Abstract
The utility model relates to a portable sclera plug used in ophthalmic vitreous body incision operation, in particular to a sclera plug used to nip, emplace and jam the sclera incision with general instruments. The portable sclera plug is composed of five parts such as plug cap, plug neck, plug shelf, plug body, plug tip, which are connected to form a nail-shape pillar with one heart. The plug cap can be nipped with the grooves of the specially equipped sclera plug forceps to jam the sclera incision. The plug neck can be nipped with micro toothed forceps or toothless forceps, or even micro needle holder. The plug tip is of blunt pyramidal shape, convenient to plug into the sclera incision. The plug shelf and the sclera surface stick tightly to prevent the plug body from excessive penetration. The diameter of the plug body is longer than that of the sclera incision so that it can jam the incision effectively. The portable sclera plug is simple-structured, can be used to promptly and stably nip, emplace and take out with general ophthalmic instruments and professional instruments. The utility model is free from slipping off and convenient to operate.
Description
Affiliated technical field
This utility model relates to a kind of ophthalmological instruments that is used for vitrectomy operation, especially can use general instruments clamping easily, lay and stop up the scleral plugs of scleral incision.
Background technology
At present, in the vitrectomy operation of standard triple channel scleral incision, applied common scleral plugs is made up of plug tip, cock body, cock cap three parts.When apparatuses such as vitrectomy head, lighting fiber when scleral incision takes out, overflow in a large number and keep intraocular pressure for preventing intraocular irrigating solution, need the sclera plug tip is inserted scleral incision, and utilize the sclera cock body to stop up otch.Yet, because the scleral plugs bodily form is tiny, existence only has the defective that the sclera cock cap links to each other with cock body in the design, in use because of cock cap and the tight card of placing plate or scleral incision surface, even the scleral plugs tweezer clamping that application specific is equipped with, also be difficult for scleral plugs is easily taken out or fills in, also cause the clamping shakiness to cause scleral plugs sometimes and come off, influenced carrying out smoothly of operation.
Summary of the invention
For the inconvenience that solves existing scleral plugs clamping, fills in and take out, this utility model provides a kind of scleral plugs with stop, this scleral plugs can not only be filled in and effective obstruction scleral incision easily, and can use scleral plugs tweezer, the micro-toothed forceps of typical ophthalmic or Smooth forceps, even the clamping easily of micro-needle holder, lay and take out.
The technical scheme that its technical problem that solves this utility model adopts is: the easy-to-hold type scleral plugs is connected to a concentric spike cylinder by cock cap, plug neck, plug shelves, cock body, plug tip 5 parts.When using the easy-to-hold type scleral plugs in operation, cock cap, plug neck all can be respectively applied for clamping, scleral plugs slippage when cock cap also can prevent clamping plug neck; Plug shelves can to prevent that cock body from inserting dark with the tight card of scleral surface, and auxiliary cock body prevents that infusion liquid from outflowing; Plug tip is blunt nosed cone shape can make cock body insert scleral incision smoothly.
The beneficial effects of the utility model are, can stop up scleral incision effectively and prevent the too much seepage of intraocular irrigation, use scleral plugs tweezer, micro-toothed forceps or Smooth forceps even the clamping easily of micro-needle holder, lay and take out, the slippage that minimizing causes because of the clamping shakiness, thereby the saving operating time, its structure is also simple.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a profile of the present utility model.
Fig. 2 is an easy-to-hold type scleral plugs embodiment sketch map.
1. cock caps among the figure, 2. plug neck, 3. plug shelves, 4. cock body, 5. plug tip, 6. Smooth forceps, 7. eyeball sclera, 8. scleral plugs tweezer.
The specific embodiment
In accompanying drawing 1, the easy-to-hold type scleral plugs is by cock cap (1), and plug neck (2) is filled in shelves (3), and cock body (4), plug tip (5) are connected to a concentric spike cylinder, and cock cap (1) is the spherical surface body of diameter of section 1.8-2.5mm, spherical radius 3.0-5.0mm; Plug neck (2) is the cylinder of high 0.4-0.8mm, diameter 0.89-0.95mm; Plug shelves (3) are the cylinder of thick 0.15-0.30mm, diameter 0.18-0.30mm; The cylinder of the long 1.2-1.5mm of cock body (4), diameter 0.89-0.95mm; Plug tip (5) is the blunt nosed cone of long 0.6-1.2mm.
2 couples of embodiment of the present utility model are described further below in conjunction with accompanying drawing.
When stopping up scleral incision, the groove clamping cock cap (1) of scleral plugs tweezer (8) head end of available special outfit, also available micro-toothed forceps or Smooth forceps (6) even micro-needle holder clamping plug neck (2), with scleral plugs after placing plate takes off, earlier plug tip (5) is inserted in the otch on eyeball sclera (7) surface, then cock body (4) is inserted scleral incision downwards, tightly obedient until plug shelves (3) and scleral surface, because of cock body diameter 0.9mm is thick slightly than scleral incision diameter 0.89mm, prevents a large amount of seepages of intraocular irrigating solution and keep intraocular pressure so can effectively stop up.When finish stopping up, with above-mentioned apparatus scleral plugs is extracted and to be put back to placing plate and get final product.
In a word, the easy-to-hold type scleral plugs that this utility model provides, operating theater instruments is simple in structure, can use the general special equipment that reaches to carry out quick clamping, lay and take out, clamping is stable to be difficult for slippage, easy and simple to handle, and can effectively stop up scleral incision, have safety, effective, practical characteristics.
Claims (6)
