摘　　要：目的评估1470 nm半导体激光治疗仪(简称:科瑞达治疗仪)对犬前列腺切除术的有效性。方法选取成年雄性Beagle犬28只,随机分为3组,即假手术组3只、试验组15只和同类对照组10只;其中试验组又分为120 W/50 W、150 W/50 W、160 W/50 W的汽化切割/凝固止血3个小组;同类对照组又分为120 W/50 W、150 W/50 W的汽化切割/凝固止血2个小组;每小组各5只。试验组和同类对照组均在电切镜下经膀胱颈入口行犬前列腺切除术。术中观察产品的操作适配性和有效性;术后观察犬的一般体征,以及在术前、术后即刻、3 d、7 d、28 d时取血测定血液生化和血液学指标;分别在术后1 h、4周时,行超声和电切镜下观察尿道前列腺部情况,并取前列腺组织进行HE染色分析术后1 h的凝固层厚度和4周尿道上皮修复情况。结果术中,试验品和同类对照品进行犬前列腺切除术的操作性能良好,具有较好的汽化切割和凝固止血性能;术后对犬的一般体征、血液学和血液生化指标均未见明显影响;且超声显示术后即刻均可见尿道扩张,尿道上皮回声略有增强;4周时,可见前列腺组织实质为略低回声,内部为均匀分布细小点状回声,包膜呈线状高回声,与假手术组一致。测量分析显示,试验组和同类对照组汽化切割前列腺组织重量约为0.91~1.33 g,切除比例达17.11%~20.27%;且随汽化切割功率的增加,激光发射时间逐渐减少,而汽化切割速度和效能均有所增加;但试验组与同类对照组比较均未见明显差异(P>0.05)。电切镜下可见试验组和同类对照组在术后1 h时前列腺尿道部创面呈烧灼样改变,创面和正常尿路上皮分界明显;4周时,前列腺部尿路上皮已修复平整,周围正常尿路上皮分界较模糊。同样,病理观察也显示,术后1 h时试验组和同类对照组均可见前列腺尿道口损伤明显,创面表面有少量碳化和凝固性坏死,少量炎性细胞聚集,凝固层�Objective To evaluate the effectiveness of a 1470 nm semiconductor laser therapeutic instrument(referred to as a curestar therapeutic instrument)for prostatectomy in Beagle dogs.Methods Twenty⁃eight adult male Beagle dogs were randomly divided into three groups:sham(n=3),experimental(n=15),and control(n=10).The experimental group was further divided into three subgroups:120 W/50 W,150 W/50 W,and 160 W/50 W for vaporization cutting/coagulation hemostasis.The control group was divided into two subgroups:120 W/50 W and 150 W/50 W with five in each subgroup.Experimental and control groups underwent canine prostatectomy through the entrance of the bladder neck under electrocision.The operational suitability and effectiveness of the product during surgery were assessed.After the operation,the general condition of the dogs was observed,and blood biochemical and hematological indicators were measured before,immediately after,and at 3,7,and 28 days after the operation.At 1 h and 4 weeks after surgery,B⁃ultrasound and electric resection were performed under anesthesia to observe the conditions of the urethra and prostate,and prostatic tissue was subjected to HE staining for pathological observations.The thickness of the coagulation layer at 1 h after the operation and repair of the urothelial epithelium at 4 weeks were analyzed.Results During the operation,experimental and control groups had good operability and showed good vaporization cutting and coagulation hemostasis performance.After the operation,no significant effects were observed on the general condition,and blood biochemical and hematological indicators of the dogs.Ultrasound showed that the urethral expansion was visible immediately after the operation,and the echo of the urethral epithelium was slightly enhanced.At 4 weeks,the prostate tissue had a slightly low echo with uniformly distributed small point⁃like echoes inside,and the capsule had a linearly high echo,consistent with the sham group.The weight of the vaporized prostate tissue in experimental an
