Detailed Description
The invention is further explained below with reference to the drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention have been described by way of illustration only. Needless to say, a person skilled in the art will recognize that the described embodiments can be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
As shown in fig. 1, 2 and 3, the conjunctiva retractor for ophthalmology is used for pulling a conjunctival incision to expose internal tissues when performing eye surgery. Specifically include operating handle 1, operating handle 1's end connection has drag hook connecting rod 2, just operating handle 1 with the coaxial setting of drag hook connecting rod 2, so as to pass through during operating handle 1 operates, with accurate location is realized in the cooperation of drag hook connecting rod 2. The operating handle 1 and the drag hook connecting rod 2 are fixedly connected and are in smooth transition connection, so that the connection part between the operating handle and the drag hook connecting rod is uniform and smooth, the edges can be prevented from scraping and rubbing the periphery of the eye, and the use is safer. Of course, the two can be arranged in a split structure, namely the drag hook connecting rod 2 is in threaded connection with the end part of the operating handle 1, so that the two can be easily separated, and the replacement can be conveniently carried out by thorough disinfection or partial damage.
In this embodiment, one end of the draw hook connecting rod 2, which is far away from the operating handle 1, is fixedly connected with a conjunctiva puller 3, the width of the conjunctiva puller 3 is respectively greater than the width of the draw hook connecting rod 2 and the width of the operating handle 1, and the outer end of the conjunctiva puller 3 is fixedly connected with a draw hook body 4 which is bent towards the side portion of the operating handle 1. The overall length of the operating handle 1, the drag hook connecting rod 2, the conjunctiva pull head 3 and the drag hook body 4 is not more than 110mm, wherein the operating handle 1 is about 70mm, the drag hook connecting rod 2 is about 30mm, the thickness of the operating handle 1 is the largest, and the thickness of the operating handle 1 is 2-4 mmm. The conjunctiva retractor is small and exquisite integrally through the size matching, and the surgical shielding or the influence on the surgical field is avoided to the maximum extent.
