In order to solve the technical problem, the utility model provides a pterygium scalpel, which comprises a handle, a scraping end arranged at one end of the handle and a scraping end arranged at the other end of the handle; the scraping end comprises a connecting part connected with the handle and a hook part arranged at the end part of the connecting part, and an inclined scraping surface is arranged on one side of the hook part close to the handle; the scraping end comprises a clamping part connected with the handle and a blade fixed on the clamping part, and one side of the blade is an arc-shaped scraping plane with a sharp edge.

Preferably, the angle α between the hook portion and the connecting portion ranges from 90 ° to 100 °.

Preferably, the angle β of the inclined scraping surface is in the range of 5 ° to 10 °.

Preferably, the outer surface of the handle is provided with a plurality of sections of anti-skid grains.

Preferably, the length of the connecting part is 2-3 cm, and the length of the hook part is 3-4 mm.

Preferably, the scalpel is made of stainless steel.

The utility model relates to a pterygium scalpel compares with current design, and its advantage lies in: the utility model discloses the utilization strikes off the end and combine mutually, strike off the hook portion of end more meticulous, it is nimble, a pterygium tissue for separating the long-income corneal tissue, can "hook in its operation process, choose", the flexibility of operation has been strengthened, greatly reduced uses the risk that damages the cornea when having the blunt nature separation of tweezers centre gripping pterygium tissue row in the conventional operation, the blade size of scraping the end more is suitable for the meticulous operation of ophthalmology, a blade for scrape the corneal surface of a wound to level, avoid pathological change tissue to remain, more do benefit to surface of a wound restoration, reduce postoperative astigmatism and form, postoperative infection, complication risks such as corneal perforation. This product simple structure, the practicality is strong, fills pterygium surgical instruments blank, facilitate promotion.

Detailed Description

The utility model relates to a pterygium scalpel, including handle 10, strike off end 20, strickle off end 30. The invention is described in detail below with reference to the accompanying figures 1-2 and the specific embodiments.

As shown in fig. 1, the pterygium scalpel includes a cylindrical handle 10, and a plurality of anti-slip lines 11 are formed on an outer surface of the handle 10. The length of the handle 10 is 9-10 cm, and preferably 8 cm. At one end of the handle 10 is attached a hooked scraping end 20 and at the other end is a blade-like scraping end 30.

As shown in fig. 2, the scraping end 20 comprises a connecting part 21 connected with the handle 10 and a hook part 22 arranged at the end part of the connecting part 21, the angle α between the hook part 22 and the connecting part 21 ranges from 90 degrees to 100 degrees, preferably 90 degrees, one side of the hook part 22 close to the handle is provided with a beveled scraping surface 221 of a sharp edge, the angle β of the beveled scraping surface 221 ranges from 5 degrees to 10 degrees, the tip of the hook part 22 is provided with a round corner for avoiding scratches, and the hook part 22 is mainly used for separating pterygium tissues growing into the cornea and scraping pathological tissues.

The length of the connecting part 21 of the scraping end 20 is 2-3 cm, preferably 2.5cm, and the length of the hook part 22 is 3-4 mm, preferably 3 mm.
