Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical surgical instruments, in particular to a guiding and fixing instrument for eyelid bag surgery via a conjunctival approach. Background Art
[0002] Internal eyelid bag surgery is a transconjunctival approach to eyelid bag surgery. It has gradually become the choice of more people because it does not leave scars on the body surface, has a short operation time and little trauma. The main operation of internal eyelid bag surgery is the removal of excess fat in the orbital septum of the lower eyelid and the transfer of remaining fat. It is suitable for patients with eyelid bags with sunken tear troughs, prominent eyelid bags but tight skin, and who do not need to remove excess skin. There are various surgical procedures for internal eyelid bag surgery. One of the surgical methods is to release the orbital septum fat of the lower eyelid, remove the excess fat, and then fix it to the deep orbicularis oculi muscle below the orbital rim with absorbable sutures, thereby reducing the eyelid bag while filling the tear trough.
[0003] However, current surgical instruments cannot perform the orbital septum fat fixation operation well. The surgical field of eyelid bag surgery via the conjunctival approach is limited, and it is only separated to the inferior orbital margin downwards, and the deep surgical field is narrow. If the existing medical suture needle with a thread on the needle tail is used, it is necessary to pass the suture needle through the orbicularis oculi muscle through the narrow orbital margin, or increase the skin surface incision. The needle holder deep in the surgical field is inconvenient to operate, which will prolong the operation time, and the one-time success rate of the operation is low, which causes greater damage to the patient. Adding an external incision will form a scar, so more professional surgical instruments are needed to help complete this step faster, more accurately, and more minimally invasively.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be further described clearly and completely in combination with the drawings in the embodiments of the utility model. It should be noted that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0021] The surgical field of eyelid bag surgery through the conjunctival approach is limited, and the surgical field is narrow deep down. If the existing medical suture needle with a thread at the needle tail is used, it is necessary to pass the suture needle through the orbicularis oculi muscle through the narrow orbital rim, or increase the skin surface incision. The needle holder deep in the surgical field is inconvenient to operate, which will prolong the operation time, and the success rate of the operation is low, which causes greater damage to the patient. Adding an external incision will form a scar, so more professional surgical instruments are needed to help complete this step faster, more accurately, and more minimally invasively.
[0022] The utility model provides a guiding and fixing device for eyelid bag surgery via a transconjunctival approach, which effectively solves the problem that the surgical instruments in the prior art cannot well complete the operation step of orbital septum fat fixation.
[0023] Figure 1 A schematic diagram of the structure of the guiding and fixing device provided in the embodiment of the utility model is shown in FIG. Figure 1 As shown, the guiding and fixing device comprises: a needle tip portion 11, an arc-shaped body portion 14 and a straight extension portion 15, wherein:
[0024] The needle tip 11 is a triangular needle tip. Since the guide and fixation device needs to penetrate the skin, and the relatively blunt needle tip of a round needle is difficult to accomplish, a sharper triangular needle tip structure is selected. The tip of the triangular needle is triangular and very sharp, which is suitable for penetrating tough tissues such as the skin, and can facilitate the guide and fixation device to smoothly penetrate the skin of the zygomatic region and expose upward to the surgical field.
[0025] The front end of the needle tip 11 is provided with a threading hole 12 which is perpendicular to the needle back. The threading hole 12 is located 1 mm below the tip of the needle tip 11. The diameter of the threading hole 12 is 0.5 mm. The threading hole 12 enables the guide fixation device to have a thread at the tip, so that the target tissue can be reached through a new approach, and tissue penetration and suture traction can be completed while the end of the guide fixation device is visible and controllable throughout the entire process.
[0026] The arcuate main body portion 14 has an arc angle of 3 / 8 and a length of 32 mm. The 3 / 8 arc with a length of 32 mm is most suitable for surgical needs, but the length is insufficient. In order to allow the tip to be fully exposed to the surgical field, a straight extension portion 15 is provided at the end of the arcuate main body portion 14 to be smoothly connected to the arcuate main body portion 14. The straight extension portion 15 is 32 mm in length. During the operation, the straight extension portion 15 is clamped with a needle holder, thereby achieving more convenient and continuous surgical operations.
[0027] Since the tip of the guide and fixation instrument is not visible after entering the tissue, in order to more clearly grasp the position of the tip, especially whether the tip has entered the orbicularis oculi muscle, a marking band 13 is provided on the arc-shaped main body 14. The marking band 13 is a black marking band. The distance between the black marking band and the needle tip 11 is 8 mm, and the width of the black marking band is 1 mm. In the process of withdrawing the guide and fixation instrument, if the black marking band is seen exposed, it means that the tip of the guide and fixation instrument is most likely in the orbicularis oculi muscle at this time, so as to prevent the orbital septum fat from not being connected to the orbicularis oculi muscle due to excessive withdrawal. Due to individual differences, the distance between the black marking band and the needle tip 11 is set to 8 mm, which is only suitable for most patients. When used specifically, the surgeon can adjust it accordingly during the operation.
[0028] Another aspect of the present invention provides a method for using the guiding and fixing device in the above embodiment. Figures 2 to 4 FIG. 1 is a schematic diagram of the use of the guiding and fixing device in the embodiment of the utility model. Figure 2 As shown, first, the tip of the guiding and fixing instrument 32 is vertically inserted into the skin 22 from the intersection of the vertical line between the nose wing and the pupil midline and the inner and outer edges of the cornea, and then passes through the subcutaneous fat 23, the orbicularis oculi muscle 26 and the posterior fascia of the orbicularis oculi muscle 27 upward and inward in sequence to enter the surgical field, and the end of the absorbable suture 28 that has passed through the orbital septum fat 25 is passed through the threading hole at the tip of the guiding and fixing instrument 32; Figure 3 As shown, the guide fixation device 32 is then withdrawn outward until the black marking band is visible and exposed from the skin 22, at which time the tip of the guide fixation device 32 with the absorbable suture 28 is located in the orbicularis oculi muscle 26; Figure 4As shown, the direction is finally adjusted and the tip of the guiding and fixing instrument 32 is pushed into the surgical field again. At this time, the absorbable suture 28 has connected the orbital fat 25 and the orbicularis oculi muscle 26. The end of the absorbable suture 28 is pulled out, and the guiding and fixing instrument 32 is withdrawn from the skin 22. The operation is completed by directly tying a knot. At this time, the orbital fat 25 is fixed to the orbicularis oculi muscle 26.
[0029] To sum up, the guiding and fixing instrument for transconjunctival eyelid bag surgery provided by the utility model has a simple structure, and the tip of the instrument uses a triangular needle tip structure to facilitate penetration of the skin. The suture is passed through the tissue through the small hole at the tip of the guiding and fixing instrument, thereby achieving the purpose of passing the suture through the tissue in a completely visible and controllable situation; the black marking tape on the guiding and fixing instrument can help the surgeon determine the position of the tip, and the straight extension part at the end of the guiding and fixing instrument can help the surgeon achieve continuous operation throughout the entire process; the utility model can effectively shorten the operation time, reduce the damage of the operation to the patient, and improve the success rate and safety of the operation.
