Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hook wire tools, in particular to a laryngeal cavity puncture guiding device. Background Art
[0002] When performing surgical operations in the laryngeal cavity, since the silicone laryngeal membrane implantation surgery is a treatment method adopted when complications such as vocal cord adhesion occur after laryngeal surgery, in the specific treatment process, the throat where the vocal cords are adhered is usually incised, and the silicone laryngeal membrane is placed between the adhesions to separate them to prevent adhesion. In addition, after the silicone laryngeal membrane is placed, in order to fix the silicone laryngeal membrane, a suturing and fixing operation is usually required. When performing the suturing and fixing operation, a puncture needle and suture are required. In addition, after the suture is introduced into the larynx and knotted to fix the silicone membrane, it is necessary to tie a knot inside and outside the larynx. When the silicone membrane is removed, the suture knot needs to be removed together. In order to smoothly guide the lead in the laryngeal cavity to the outside, a corresponding puncture guide device is usually used.
[0003] The utility model patent with the authorization announcement number CN209091482U discloses a new laryngeal puncture-intracavity suture guide, which includes an outer sleeve and an inner core; when the inner core and the outer sleeve are assembled, the distal end of the inner core extends out from the distal end of the outer sleeve, and the distal end of the inner core is provided with a barb-shaped structure. Its advantages are as follows: after the puncture needle punctures the laryngeal cavity, the inner core is pulled out and a special inner core with a barb-shaped structure is inserted, the barb-shaped structure hooks and clamps the suture in the laryngeal cavity, and the cannula needle is withdrawn to guide the suture from the laryngeal cavity to the outside of the larynx.
[0004] Although this technical solution has the advantages of reducing laryngeal tissue puncture damage, easy operation, lowering the re-adhesion rate of vocal cords after surgery, and improving the quality of life of patients, this technical solution, when used specifically, is to hook the suture outward through a barb-shaped structure. Since the barb-shaped structure is arranged toward one side, when the suture is on the side away from the barb-shaped structure, it is difficult to ensure that the suture is normally stuck in the barb-shaped structure. In addition, the opening of the barb-shaped structure is exposed to the outside, and it is difficult to ensure that the suture is stably stuck in the barb-shaped structure and pulled out. Finally, the barb-shaped structure is relatively sharp. As the barb-shaped structure moves, it is easy to cause secondary damage to the larynx, causing secondary harm to the patient. In view of this, we propose a laryngeal cavity puncture guide device. Utility Model Content
[0005] The purpose of the utility model is to provide a laryngeal puncture guiding device to solve the defects mentioned in the above background technology.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model can insert the puncture needle into the laryngeal cavity through the arrangement. After the puncture needle drives the hook thread needle to be inserted together, the spiral hook thread loop is passed out from the end of the puncture needle. At this time, no matter in which direction the suture is located, the spiral hook thread loop is driven to rotate by rotating the hook thread needle, so that the suture is wound around the spiral hook thread loop along the end of the spiral hook thread loop. At this time, it can be ensured that the suture is not easy to slip off the spiral hook thread loop, and then the hook thread needle is pulled outward to realize the pulling of the suture from the guide hole to the outside of the larynx to complete the guiding operation. In addition, since the spiral hook thread loop is spiral-shaped and has a relatively smooth surface, it is not easy to cause secondary scratches, and is convenient to use, thereby achieving the effect of facilitating stable guiding operation and reducing secondary scratches.
[0017] 2. The utility model can make the end of the spiral hook wire loop more rounded by providing a spherical end head, so that the spiral hook wire loop is not easy to cause secondary damage to the throat when rotating. BRIEF DESCRIPTION OF THE DRAWINGS
