Ophthalmic hook-shaped suture needle beneficial to nasolacrimal duct anastomosis time of chronic dacryocystitis

Abstract

The invention discloses an ophthalmic hook-shaped suture needle beneficial to nasolacrimal duct anastomosis time of chronic dacryocystitis. The bottom end of a supporting rod is fixedly connected to the top end of the needle tail, a needle tip is fixedly connected to the other arc-shaped end of the needle tail, a fine hole is formed in the upper end of the needle tip, a sliding groove is formed inthe side end, located at the bottom end of the needle hole, of the needle tip, a supporting shaft is movably installed at the bottom end of the central axis of a movable shaft, and drum bodies are fixedly connected to the two sides of the inner wall of the movable shaft. When the face, with a magnet, of the movable shaft turns to the face, with a magnetic block, of the supporting shaft, the mutual attraction force makes the drum bodies close to the inner side and extrude the axis rod of the movable shaft, thus air flow in the axis rod extrudes to a wrapping sleeve, with the clockwise rotationof the movable shaft, the wrapping sleeve can be pushed to move up and down, the length of needle thread required at the needle tip during the process of sewing the wound for patients can be quicklyprolonged by a user, and the time for medical staff to anastomose the affected part of the patients during the operation is saved.

Description

technical field [0001] The invention relates to the technical field of ophthalmic hook-shaped suture needles, in particular to an ophthalmic hook-shaped suture needle which is beneficial to the anastomosis time of chronic dacryocystitis nasolacrimal duct. Background technique [0002] If a broken thread is suddenly found during the operation, it is necessary to change the thread or connect it. In the process of processing the thread, if the broken thread is pulled out, it will cause certain trauma to the patient's affected area, so it can only be removed. Knotted and processed immediately afterwards, the connected thread ends will affect the density of wound suturing. When pulling thread on the wound during crochet suture, it is easy to slip the sewing thread from the hole of the crochet needle, which makes the sewing time of the patient Lengthening increases the pain of the patient during the operation. [0003] During the sewing process, the medical staff only use the fir...
