The utility model relates to a titanium screw placer for skull base repair for surgery, which comprises a fixed handle, a clamp handle, a sleeve, a clamp cable, two clamps and a U-shaped titanium screw. The upper part of the fixed handle and the clamp handle is connected by a pin shaft, a supporting spring is arranged between the fixed handle and the lower part of the clamp handle, a sleeve rotating fixing screw is arranged on the outer wall of the sleeve support seat, and a clamp is arranged at the front end of the sleeve. Trough. The rear part of the two clamps is staggered and overlapped in the clamp groove. The front part of the two clamps is concavely provided with titanium nail chucks, the U-shaped titanium nails are clamped in the titanium nail chucks, and the isolation chucks are respectively arranged in the front end of the two clamps. The front end of the clamp cable is respectively fixed in the cable hole outside the back part of the two clamps, and the back end of the clamp cable passes through the casing and the cable through respectively. Fixed connection with adjusting bolt after hole. The invention can obviously save operation time, reduce patient risk and operation cost. At the same time, it can achieve better results and avoid cerebrospinal fluid leakage.

一种手术用颅底修补钛钉放置器
本专利技术涉及医用器械
,特别涉及一种神经内镜经鼻扩大入路手术中缝合使用的颅底修补钛钉放置器。
技术介绍
对于切除颅咽管瘤和鞍结节等肿瘤手术,有开颅手术和神经内镜经鼻扩大入路。神经内镜经鼻扩大入路具有如下优势:(1)对于颅底中线区的肿瘤,神经内镜经鼻扩大入路与肿瘤的生长方向同轴,可以直视下处理肿瘤、视交叉等重要结构。(2)较传统开颅手术对垂体柄的保护更好。(3)神经内镜下几乎无视野死角,可直视下分离肿瘤与视交叉、下丘脑及穿支血管,并保护上述重要结构,还可发现组织间隙及第三脑室内部的残余肿瘤,提高肿瘤的切除率。患者术后围手术期高热、尿崩、水钠电解质紊乱发生率较传统开颅术低且易纠正。(4)患者术后恢复快,住院时间缩短。但是,神经内镜经鼻扩大入路切除颅咽管瘤也有一定的局限性,其中最重要的就是脑脊液漏的发生率高。神经内镜经鼻扩大入路切除颅咽管瘤术中为切除肿瘤需要打开蛛网膜下腔,所以切除肿瘤后均出现较大面积的颅底缺损和高流量脑脊液漏。术后一旦出现脑脊液漏则可能导致患者感染,出现脑积水,严重时可导致脑室炎引起患者死亡,后果十分严重。国内学者 ...
