Abstract
The utility model relates to a sleeving bolt for ophthalmic minimally invasive surgery, and belongs to medical instruments. The sleeving bolt is a bolt with a diameter being adapted to the inner diameter of a 23G sleeving, and the outer end of the bolt is provided with a protruding blocking stage. The sleeving bolt for the ophthalmic minimally invasive surgery is simple in structure, tube drawing is convenient, tube drawing complications can be avoid, and surgery quality and treatment effect can be guaranteed.
Description
Technical field
This utility model relates to a kind of ophthalmology Minimally Invasive Surgery sleeve pipe bolt, belongs to medical apparatus and instruments.
Technical background
For the Clinical Ophthalmology operation, modern operation on vitreous has entered Wicresoft's epoch, and the 23G operation on vitreous is extensive, the most effective Wicresoft's mode of using at present.When operation finishes, need to extract the 23G sleeve pipe, in order to prevent that basilar part residual glass body from following sleeve pipe to amphiblestroid tractive or eye inner tissue and deviating from, the patient will be placed on optical fibers or glass crop and pull out sleeve pipe in the sleeve pipe again, and can only one-handed performance during tube drawing, be unfavorable for accurately grasping the tube drawing direction, operation is inconvenient, also is unfavorable for the closure of otch, also because there is not other assistive device to help close incisions, cause easily the tube drawing complication, directly impact operation quality and therapeutic effect.
The utility model content
The purpose of this utility model is to provide a kind of ophthalmology Minimally Invasive Surgery sleeve pipe bolt, and is simple in structure, makes things convenient for the tube drawing operation, can avoid the generation of tube drawing complication, guarantees operation quality and therapeutic effect.
Ophthalmology Minimally Invasive Surgery sleeve pipe bolt described in the utility model is the thromboembolism that a diameter and 23G casing inner diameter adapt, and the outer end of thromboembolism is provided with outstanding gear platform.
When using operation, directly the sleeve pipe bolt is inserted in the 23G cannula cavity and just in time sleeve pipe is blocked, can not injure eye inner tissue again.Outstanding gear platform has stoped the sleeve pipe bolt to fall into ophthalmic, can realize bimanualness like this when tube drawing, thereby effective close incisions has been avoided the generation of tube drawing complication.
Optimal thromboembolism size is consistent with the 23G casing inner diameter, is respectively: thromboembolism length is 6mm, and diameter is 0.6mm, and the gear platform is rounded, and gear platform diameter is 1.2mm.
The sleeve pipe bolt can use the suitable medical material such as silica gel, rustless steel or titanium alloy to make.
The utlity model has following beneficial effect:
This utility model ophthalmology Minimally Invasive Surgery sleeve pipe bolt, simple in structure, make things convenient for the tube drawing operation, can avoid the generation of tube drawing complication, guaranteed operation quality and therapeutic effect.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1, thromboembolism 2, gear platform.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing this utility model is further described.
Ophthalmology Minimally Invasive Surgery sleeve pipe bolt described in the utility model is the thromboembolism 1 that a diameter and 23G casing inner diameter adapt, and the outer end of thromboembolism 1 is provided with outstanding gear platform 2, the thromboembolism optimum size is: thromboembolism length is 6mm, diameter is 0.6mm, and the gear platform is rounded, and gear platform diameter is 1.2mm.
Clinically, when using operation, directly the sleeve pipe bolt is inserted in the 23G cannula cavity and just in time cannula cavity is blocked, injure eye inner tissue when avoiding extracting sleeve pipe, effectively close incisions has prevented the generation of tube drawing complication.
Claims (2)
