Orbital septum fat fixing thread knot pusher and control system

Abstract

The embodiment of the invention discloses an orbital septum fat fixing thread knot pusher and a control system. The orbital septum fat fixing thread knot pusher comprises a wire connecting lead shaftprovided with internal threads on the surface and a first penetrating conductor rod and a second penetrating conductor rod which are attached to an aluminum oxide ceramic substrate. Screw-in metal covers are tightly connected to the upper surfaces of the two sides of the aluminum oxide ceramic substrate through seal rings; through an excitation drive circuit and a signal acquisition circuit installed at the left end and the right end of the waveguide wire, the signal acquisition circuit receives displacement information from a displacement sensor, a control end of the excitation driving circuit is connected with an excitation transducer, a magnetostrictive transducer is combined with the displacement sensor to obtain the linear displacement to be measured; the knotting position wound on the inner thread wall of the knotting thread leading shaft can be effectively controlled, knotting threads are pulled through magnetic field force, knots are pushed to a suture fixing position, and therefore knotting thread displacement can be accurately and effectively controlled, deep knotting of an eye bag operation becomes easy, and an incision in the eye conjunctiva can be properly reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of plastic surgery, in particular to an orbital septal fat fixation knot pusher and a control system. Background technique [0002] Eye plastic surgery includes the cosmetic plastic surgery of the upper and lower eyelids, eyebrows and other parts, which plays a finishing role in people's appearance. It is clinically seen in medical seekers of all ages. [0003] At present, in ophthalmic plastic surgery, when performing conjunctival incision and orbital septal fat release surgery, it is necessary to fix the orbital septal fat on the eyelid margin or the tissues below the orbital rim. The location of the orbital septal fat near the eyelid margin to the palpebral conjunctiva incision is relatively far away, making suture fixation more difficult. [0004] In order to solve the above problems, in the prior art, such as a deep knotter for surgery with application number CN201020002688.4,...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of orbital septal fat fixation thread knot pusher and control system to solve the problem that in the prior art, due to the small eye bag surgery incision, it is impossible to realize the operation of knotting first and then pushing it to the suture fixation place in vitro. The problem of low accuracy of knot position
