Abstract

The utility model discloses a kind of guide for preventing prosthesis skew, it is related to orthopedic surgery auxiliary instrument technical field.The guide includes handle, handle one end two sides are puncture structure, puncture structure is equipped with guide through-hole, for the through of guide wire.Setting.The total length of guide is 18cm, the diameter range of guide wire that guide through-hole can pass is 0.5mm-1mm.When using, guide wire is connected prosthesis and is set to guide through-hole, guide is inserted into nasal cavity from incision, pulls guide wire and makes prosthesis move to predetermined position along guide direction, avoids prosthesis skew, finally cuts off guide wire, withdraws guide, and guide wire and prosthesis are left in nasal cavity, complete surgery.The utility model improves the precision and stability of nasal prosthesis implant by the cooperation of guide and guide wire, reduces the risk of surgery, and is suitable for rhinoplasty.

Description

Technical Field

[0001] This utility model relates to the field of auxiliary instruments for plastic surgery, and in particular to a guide device for preventing prosthesis misalignment. Background Technology

[0002] In rhinoplasty, nasal implant placement is a crucial step, and its success directly affects the surgical outcome. Traditional nasal implant placement methods rely heavily on the surgeon's experience and tactile sense. A channel is created in the nasal soft tissue using blunt dissection tools, and the implant is then placed in the predetermined location. However, due to a lack of auxiliary tools, the implant placement path and position may be inaccurate, leading to implant deviation, misalignment, or asymmetry, affecting postoperative appearance and function. Therefore, this invention proposes a guide device to prevent implant deviation. Utility Model Content

[0003] The present invention aims to provide a guide to prevent implant misalignment, thereby solving the problem of easy misalignment during the implantation of nasal implants in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A guide for preventing prosthesis tilting includes a handle, with puncture structures on both sides of one end of the handle, and guide through holes provided on the puncture structures for inserting guide wires. The guide through holes are elliptical through holes.

[0006] Furthermore, the total length of the guide is 18cm.

[0007] Furthermore, the diameter of the guide wire that can pass through the guide hole is between 0.5mm and 1mm.

[0008] The principle and beneficial effects of this technical solution are as follows: First, the implant to be placed is sutured to the guide suture. Then, the guide suture is passed through the guide hole, so that the guide suture, implant and guide are connected to form a whole. Then, the guide is inserted from the incision to the center of the eyebrows. Then, the guide suture is pulled to move the implant along the direction of the guide into the nasal cavity. After the implant is placed, the guide suture is cut, so that the implant remains in the nasal cavity, thus completing the placement of the implant. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0013] like Figures 1-2 The diagram shows a guide for preventing prosthesis misalignment. The guide has a total length of 18cm and includes a handle 1. One end of the handle 1 has two puncture structures 2 on both sides. The puncture structures 2 have guide holes 3. The guide holes 3 are elliptical and can accommodate traction wires with a diameter range of 0.5mm-1mm. The guide holes 3 are used for threading the guide wires.

[0014] The specific implementation process is as follows: After the nasal cavity surgical incision is completed, the guide suture is first sutured to the implant to be installed, the implant is connected to the guide suture, and the guide suture is passed through the guide hole 3, so that the implant is connected to the guide. The guide is inserted into the incision towards the brow, and then the guide suture is pulled to move the implant along the direction of the guide into the nasal cavity. Finally, the guide suture is cut from the outside, the guide is removed, and the guide suture and the implant are left inside the nasal cavity, thus completing the implant placement.

[0015] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solution of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
