目的设计泪道探通引流装置置入泪道,扩张泪道,缓解泪道狭窄,恢复泪液引流通路,消除眼表感染灶。方法设计新型泪道探通引流装置,由两端金属探子和中间的软性硅胶管组成。选择120例病人(女78例,男42例,80例慢性泪囊炎,20例泪小管断裂,20例泪小管狭窄)。1%氯麻液收敛鼻粘膜及眼表麻醉后,探通泪道,自上下泪小点插入泪道探通引流装置的探子至下鼻道前部鼻泪管开口处,用特制的鼻腔探子取出器钩出探子,硅胶管留置鼻腔内。术后每周冲洗泪道1次至1月,以后每月冲洗1次。3～6月取出引流管。泪小管断裂者插入探子后吻合泪小管。结果80例鼻泪管狭窄所致慢性泪囊炎患者流泪症状均在置管1周内消失,拔管1月后有18例慢性泪囊炎患者复发。20例泪小管断裂及20例泪小管狭窄患者术后流泪症状立即消失。拔管后观察3个月,无复发,泪道引流通畅。结论新型泪道探通引流装置治疗鼻泪管狭窄所致慢性泪囊炎、泪小管狭窄及泪小管断裂所致溢泪效果肯定,方法简单,组织创伤小,无局部及全身副作用,具有临床推广应用价值。
Objective To design the lacrimal duct exploration and drainage device into the lacrimal duct, dilate the lacrimal duct, relieve the narrow lacrimal duct, restore the drainage of the lacrimal duct and eliminate the ocular surface infection. Methods A new type of lacrimal probing device was designed, consisting of a metal probe at both ends and a soft silicone tube in the middle. A total of 120 patients (78 females, 42 males, 80 chronic dacryocystitis, 20 ruptured canalicular punctures and 20 lacrimal canaliculi) were selected. 1% chlorine anesthesia convergence of nasal mucosa and ocular surface anesthesia, probing the lacrimal duct, from the tear point into the lacrimal duct drainage device probe to the front nasolacrimal duct openings, with a special nasal probe Remove the probe hooked, silicone tube indwelling nasal cavity. Routine wash lacrimal duct 1 to January after a month after the rinse once. 3 to 6 months to remove the drainage tube. Tear canal rupture inserted into the probe after the lacrimal duct anastomosis. Results 80 cases of nasolacrimal duct stenosis patients with chronic dacryocystitis lacrimal symptoms disappear within 1 week after catheterization, extubation in January after 18 cases of chronic dacryocystitis recurrence. Twenty cases of tear tube rupture and 20 cases of lacrimal canalicular stenosis disappeared immediately after operation. After extubation observed for 3 months, no recurrence, lacrimal duct drainage patency. Conclusion The new lacrimal drainage device for the treatment of chronic dacryocystitis caused by nasolacrimal duct stenosis, lacrimal canalicular stenosis and tear tube rupture caused by tears affirmation, simple, less tissue trauma, no local and systemic side effects, with clinical promotion Value.
