镍钛记忆合金加压吻合夹在36例肠道吻合术中的应用

目的评价新型镍钛记忆合金加压吻合夹(CAC)在肠道吻合术中的临床应用效果。方法自2008年1月以来,我科将新型镍钛记忆合金加压吻合夹应用在36例肠道吻合术中,所有病例均以侧侧吻合,其中包括小肠-小肠吻合15例,回肠-结肠吻合10例,结肠-结肠吻合11例。结果本组36例手术均获得成功。全组无吻合口瘘或肠梗阻等严重并发症发生。吻合操作时间为9.6±2.8分钟,术后排气时间为3.5±1.4天。吻合夹排出体外时间为13.1±6.8天。结论新型镍钛记忆合金加压吻合夹用于肠道吻合术中,具备安全可靠、操作简便、实用性强等特点。     

A simple method for linear burn debridement

Debridement of linear burns especially on the trunk and abdomen can be challenging. Some currently used methods are technically difficult and potentially hazardous to the surgeon or the assistant. We propose a simple and effective method of linear burn debridement using towel clips. A pair of strong towel clips can be used to grasp the area of the burn at either end producing a tenting effect and therefore facilitating debridement of difficult areas. This technique provides a simple, precise and safe method of linear burn debridement.     

三孔免钛夹腹腔镜胆囊切除术的临床研究

目的：探讨三孔免钛夹腹腔镜胆囊切除术的可行性。方法：回顾性分析865例三孔免钛夹腹腔镜胆囊切除术。结果：成功完成三孔免钛夹腹腔镜胆囊切除术810例,成功率93．6％,平均手术时间51．6min,术中平均出血量33．8ml。平均住院时间3．2d,未发生大出血、胆管损伤、术后胆汁漏等并发症。术中改为四孔法53例（6．1％）,中转开腹手术2例（0．2％）。结论：三孔免钛夹腹腔镜胆囊切除术更加具有微创性,且能避免使用钛夹所致的并发症,手术安全可行。     

Mechanical and surface properties of Yasargil Phynox aneurysm clips after long-term implantation in a patient with cerebral aneurysm

This study evaluated the mechanical properties and the surface elemental composition of Yasargil Phynox aneurysm clips implanted for 10 years in a patient with cerebral aneurysm. Two Yasargil Phynox aneurysm clips implanted 10 years previously to treat a ruptured vertebral artery aneurysm were retrieved when the regrown and ruptured aneurysm was repaired with a new aneurysm clip. Two new Yasargil aneurysm clips were used as controls. Measurements of closing force, bending strength, and the elemental composition of the clip surface were performed. The closing force of the retrieved clips was similar or greater compared to the force before implantation. The bending test showed that the elastic limit and 0.2% proof load of the retrieved clip were higher than those of the unused clip, whereas the ultimate load of the retrieved clip was similar to that of the unused clip. The elemental concentration of Cr oxide on the surface of the retrieved clips was almost the same as that on the unused clips. The present study demonstrated that Yasargil Phynox aneurysm clips retain their mechanical properties and surface elemental composition in vivo for a long time, which indicates that Yasargil aneurysm clips will remain reliable in patients for extended periods.     

超声引导下简易穿刺夹在儿科肾活检中的应用

目的分析超声引导下应用简易穿刺夹肾穿刺活检术在儿科的安全性和诊断价值。方法对52例肾脏病患者,通过简易穿刺夹引导,在超声下进行经皮肾穿刺活检术,术后对其成功率和并发症发生率进行分析。结果49例取得符合病理检查的肾组织,满意率94.23%,3例未取得符合条件肾组织者均在早期开展此手术时出现。术后并发症主要为一过性肉眼血尿,肾周血肿发生率1.92%,未发现其他严重并发症。结论简易穿刺夹使用方便,无菌、安全,并能准确引导进针,成功穿得所需组织,易在基层单位推行。     

A post-processing algorithm to reduce metallic clip artifacts in CT images

Computed tomography images of cross sections containing metallic implants, such as prosthetic devices or tooth fillings, often have severe artifacts. Such artifacts may hinder medical diagnosis. We present an algorithm to reduce these artifacts. The algorithm involves the convolution back projection and its adjoint, the forward projection. It has two phases — the first phase is a crude correction compensating for beam hardening caused by the metallic objects, and the second a refinement phase. In this second phase, a topological transposition method is introduced in order to replace line integral data going through the metallic objects with the modified corresponding data of a model created from the last image reconstructed in the first phase. A significant improvement in image quality has been observed in both phantom and clinical studies.
