Internal fixation eye bag drag hook for releasing orbital septum fat through conjunctival approach

Abstract

The invention discloses an internal fixation eye bag drag hook for releasing orbital septum fat through a conjunctival approach in the field of medical instruments. The internal fixation eye bag drag hook comprises a handle, and a short drag hook and a long drag hook which are fixedly connected to the two ends of the handle, and the extension directions of the short drag hook and the long drag hook are opposite; the short draw hook is arc-shaped, and the length projection distance of the short draw hook is 0.4-0.6 CM; the long drag hook comprises a connecting piece, a lower pressing piece, an expansion piece and a positioning piece which are connected in sequence; the end, away from the lower pressing piece, of the connecting piece is fixedly connected to one end of the handle; the length of the connecting piece is 1.2-1.7 cm, and the included angle between the connecting piece and the lower pressing piece is 130-140 degrees; the expansion piece is in an arc shape, the outer convex face of the expansion piece faces the handle, the positioning piece is in an arc shape, and the inner concave face of the positioning piece faces the handle; and the overall length distance of the lower pressing piece, the expansion piece and the positioning piece is 1.8-2.2 cm. The drag hook can be better applied to orbital septum fat release surgery.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a retractor for internally fixing eye bags through a transconjunctival approach for releasing orbital septum fat. Background technique [0002] Orbital septal fat release surgery refers to the correction of eye bags and tear trough deformities by retaining orbital septal fat and filling it into the tear trough through the skin approach or conjunctival approach in the case of patients with eye bags and tear trough deformities. Avoid traditional surgical resection of excess orbital septal fat and aggravate lacrimal trough deformity, making the patient look older. [0003] At present, when performing transconjunctival orbital septal fat release surgery, short retractors are generally used to expand and separate the incision and release orbital septal fat in the early stage; afterward, long retractors are used to penetrate into the lacrimal trough for fat transfer and sutur...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned setting of connecting the long pull hook and the short pull hook to the same handle reduces the loss of the handle material. However, since the angle between the hook body of the short pull hook and the handle is 80°-100°, the short pull hook will , the action point is mainly concentrated on the retractor head, and the retractor body hardly touches the human body, which is not conducive to the pulling of the incision and easily causes the short retractor to fall off

In addition, when transferring fat, since the long retractor needs to penetrate into the lacrimal trough of the infraorbital rim, and the angle between the retractor head and the retractor body of the long retractor is 100°-170°, the long retractor can penetrate into the lacrimal trough. Afterwards, the retractor body is inclined to the side close to the eyeball, so that the suture space during fat transfer becomes smaller, which is not conducive to the operation
