Embodiment Construction

[0027] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The reference signs and components involved in the accompanying drawings are as follows:

[0029] 1. Inner core 11. Barb structure

[0030] 111. Suture sliding part 112. Suture receiving part

[0031] 113. Suture clamping part 12. Connecting body

[0032] 13. Limiting bar 14. Control handle

[0033] 2. Outer sleeve 21. Connection handle

[0034] 22. Connecting pipe 23. Limit card slot

[0035] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a new laryngeal cavity puncture-intracavitary suture guider of the present invention. The suture guide includes an outer sleeve 2 and an inner core 1; when the inner core 1 and the outer sleeve 2 are assembled, the distal end of the inner core 1 protrudes from the distal end of the outer sleeve 2, and The distal end of the inner core 1 is provided with...

Abstract

The invention relates to a novel laryngeal cavity puncture and intracavity suture guide, comprising an outer sleeve and a core. After the core and the outer sleeve are assembled, the distal end of thecore is extended out of the distal end of the outer sleeve, and the distal end of the core is provided with a barb structure. The novel laryngeal puncture and intracavity suture guide has the advantages that after a puncture needle is passed into the laryngeal cavity, the core is removed, and the special core with barb structure is inserted in; the barb structure hooks and fastens a suture in thelaryngeal cavity; a trocar is removed to guide the suture out of the throat (neck) from the laryngeal cavity; compared with the Lichtenberger laryngendoscopic suturing device, the novel puncture needle herein can accurately puncture positioned parts at upper and lower edges of the thyroid cartilage in the midline part of the neck; puncture damage to the throat tissue is effectively reduced; operating is convenient, postoperative re-adhesion rate of the vocal cord is lower, and living quality is improved for a patient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a new laryngeal cavity puncture-intracavitary suture guider. Background technique [0002] In recent years, with the development of society and the improvement of people's living standards, people's health needs and expectations for a better life have also increased accordingly. The number of patients undergoing voice-related surgery is increasing year by year, and the number of patients with secondary vocal cord adhesions is also increasing accordingly. There is an urgent need for an easy-to-operate device to prevent and treat complications such as vocal cord adhesions and laryngeal webs. [0003] Adhesion band incision and implantation of silicone membrane in the laryngeal cavity are effective surgical methods for the treatment of vocal cord adhesions and laryngeal webs. Bilateral vocal cord lesions (such as bilateral vocal cord Reinke's edema, broad-based polyps, ...
