Problems solved by technology
[0002] When the hospital performs nasolacrimal duct anastomosis for patients with chronic dacryocystitis, the skin between the corners of the eyes and the bridge of the nose should be cut to open the nasal cavity. Because the surgical wound is small and deep, when suturing the nasal mucosa, the traditional Suture needle is a kind of small round needle, and its suture direction is horizontal piercing needle, and this kind of needle is difficult to adapt to the use requirement of this kind of wound deep and small, and this has caused operation difficulty to operation trouble, causes long time, and increases patient's risk. the pain of surgery

Embodiment Construction
[0009] Shown in Figure 1: the suture needle is that the tail of the needle body 1 is connected with an integrated handle 2 through a zigzag bend body 5, and the front end of the needle body 1 is provided with a crochet needle head 3 with a pinhole 4. Crochet head 3 is a curved needle.
[0010] When implementing this technique, the distance from the tip of the crochet needle head 3 to the pinhole 4 is 1.5 mm, the diameter of the pinhole 4 can be 1.2 mm, and the distance between the pinhole 4 and the hook position can be controlled at 3 mm, that is, the length of the crochet needle head 3 is 3 mm. The curved arc of the head 3 can be controlled at 1.5 mm, and the distance between the needle tip of the crochet head 3 and the needle body 1 can be 3 mm.

The invention provides a hook-shaped suture needle for the department of ophthalmology. The suture needle is characterized in that the tail part of the body of the suture needle is connected with an integrated handle through a curved body, and the front end of the body of the suture needle is provided with a hook-shaped head with a needle hole. The hook-shaped suture needle disclosed by the invention is used for nasolacrimal duct suturing operation when dacryocystitis treatment is carried out on patients in the department of ophthalmology in hospitals; as the hook-shaped head structure with the needle hole is adopted and the curved body is adopted for connecting the handle, the hook-shaped suture needle is very suitable for operations with deep and small wounds, the structure is scientific and reasonable, the operation time can be shortened, and the pains of the patients can be reduced.
Description
technical field [0001] The invention relates to a medical suture needle, in particular to an ophthalmic hook-shaped suture needle. Background technique [0002] When the hospital performs nasolacrimal duct anastomosis for patients with chronic dacryocystitis, the skin between the corners of the eyes and the bridge of the nose should be cut to open the nasal cavity. Because the surgical wound is small and deep, when suturing the nasal mucosa, the traditional Suture needle is a kind of small round needle, and its suture direction is horizontal piercing needle, and this kind of needle is difficult to adapt to the use requirement of this kind of wound deep and small, and this has caused operation difficulty to operation trouble, causes long time, and increases patient's risk. the pain of surgery. Contents of the invention [0003] The object of the present invention is to provide an ophthalmic hook-shaped suture needle, which has a scientific structure and is convenient to us...
