Description
Technical Field
The utility model relates to the technical field of medical instruments, and particularly provides an annular laser emitting head for anal fistula operation and a corresponding annular laser emitter.
Background
Anal fistula is a common anorectal disease, and the operation is the gold standard for anal fistula treatment (consensus of Chinese experts for anal fistula diagnosis and treatment (2020 edition); J. Zhonghua gastrointestinal surgery, 2020,23(12): 1123-. Conventional anal fistula excisions or incisional stringing have a high recurrence rate and present a serious risk of fecal incontinence due to sphincter muscle damage. The ideal mode of anal fistula operation is to not only completely close the fistula and prevent recurrence, but also avoid damaging surrounding tissues and reduce complications, whereas the traditional "cold knife cutting" mode is difficult to meet these requirements. Nowadays, the operation for protecting sphincter becomes the main attack direction of anal fistula treatment. In recent years, a ring-shaped laser closure (Fistula-trap laser closure, FiLaC)TM) Is gradually applied to treatment. FiLaCTMThe method is a novel anal fistula operation for eliminating fistula by using the thermal effect of special annular laser, and can be used for five-year experience of anal fistula management by using Wilhelm A, Fiebig A and Krawczak M.FilaC lasers in references: long-term follow-up from a single institution Tech Coloprotol, 2017,21(4): 269-276; the best indications for Marref I, Spindler L, Aubert M, Lemarchand N, fatallih N, pommararet E, Soudan D, Pillant-le Moult H, Safa Far E, Fellous K, croche E, Mory B, Benfredj P, de Parades v. A prospective cohort of 69 consecutive patients Tech Coloprotol, 2019,23(9): 893-897. Furthermore, FiLaCTMThe laser penetration depth is 2-3 mm, and the operation safety is guaranteed.
Currently FiLaCTMThe launching head can not look directly at the fistula, so that the branch sinus is easy to miss, and the healing rate is reduced. Furthermore, FiLaCTMBy adopting the side light emitting mode, tissue fragments and secretion in the sinus cannot be eliminated, vaporization of epithelial cells on the wall of the sinus is prevented, the sinus closing is affected, and the risk of recurrence is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a ring-shaped laser emitting head for anal fistula operation and a corresponding ring-shaped laser emitter.
In order to achieve the purpose, the technical scheme of the annular laser emitting head for the anal fistula operation is as follows:
the optical fiber head comprises an optical fiber head part and a quartz cap sleeved outside the optical fiber head part, wherein a plurality of laser light outlets are formed in the side surface of the optical fiber head part, and an inclined optical reflection part is arranged inside the quartz cap, so that laser emitted by the laser light outlets firstly passes through the reflection part and then faces the front and the side of the emitting head.
Preferably, the length of the quartz cap is 2-2.5 mm.
Preferably, the length of the quartz cap is 2.5 mm.
