ABSTRACT
Objective To develop a new radial artery puncture fixing device to conquer the deficiencies of traditional method. Methods The device was composed of an arm support,a hand support,a wrist part,an arm fixing belt,a palm fixing belt and a tourniquet.The arm support was concave-shaped,and was connected with the hand support with the wrist part.The wrist part had a raised block which was gifted with an inflatable bag.The balloon linked with an inflation balloon with an inflation tube.There was a valve between the inflation tube and balloon.The fixing belt had one end directly connected with the arm support, hand support and wrist part, and the other end linked with the other ends of the above components with Velcro. There was a compression hemostatic balloon at the internal surface of the tourniquet. Results The device behaved well in puncture time and success rate,and decreased the incidence rates of errhysis and hematoma after withdrawing the puncture needle while increased the satisfaction of medical staffs and patients. Conclusion The device gains advantages in simple structure,convenience,practicability and safety,and meets the desired requirements.[Chinese Medical Equipment Jour-nal,2018,39(5):44-46]
ABSTRACT
Objective To develop a disposable negative pressure syringe to solve the problems in bone marrow aspiration. Methods The syringe was composed of an injector and a self-contained puncture needle.The injector consisted of a barrel,a plunger and a tip.The plunger had its front end placed in the barrel and connected with the tip.The tip clung to the inner wall and could slide along it,and the upper end of the cylinder was connected closely with a negative-pressure sealing cap.A negative-pressure cavity was formed between the sealing cap and the tip,and an anticoagulation layer existed at the cylinder inner wall in the cavity.The blood taking needle was made up of a bone puncture needle and a hub.Results The developed syringe gained stable negative pressure,low time and workload consumption during bone marrow aspiration when compared with the conventional tools. Conclusion The syringe increases the quality of bone marrow aspiration while decreases the workload of medical staffs,and thus is worthy promoting practically.
ABSTRACT
<p><b>OBJECTIVE</b>The aim of this study was to describe a new technique of combined hyoid bone and thyrohyoid membrane flap in laryngeal reconstruction after tumor resection, and to evaluate outcome.</p><p><b>METHODS</b>Six patients requiring an frontal partial laryngectomy for cancer were enrolled between September 2008 and August 2012.</p><p><b>RESULTS</b>Nasogastric feeding was initiated within 24 hours. The mean times to swallow batter, ability to drink water and removal of the nasogastric tube were 2.6, 5.5 and 6.3 days. All patients had good respiratory function. There were no deaths, and no reports of postoperative dyspnea or dysphagia. The vocal quality was satisfactory, slightly deeper and raspy, and the volume was weak when calling. The final follow-up assessment was in August 2012, and the overall mean follow-up period was 29.5months, range 14 to 47 months. Case two subsequently underwent total laryngectomy for recurrence in the paraglottic space, but there was no evidence of further tumor recurrence at the final assessment.</p><p><b>CONCLUSIONS</b>The combined muscle-pedicle hyoid bone and thyrohyoid membrane flap is a reliable graft for one-stage repair of laryngotracheal defects, providing effective repair of the mucosa and cartilage support. Vocal quality, swallowing function and ventilation after the procedure were favorable.</p>

<p><b>OBJECTIVE</b>To evaluate the value of using a linear stapler device for the closure of the pharynx during total laryngectomy.</p><p><b>METHODS</b>Sixteen total laryngectomies were performed between August 2010 and December 2011, during the operation, the TA 60 linear stapler was used for pharyngeal closure. Among these patients, two patients had the history of pre-operative radiotherapy, four patients recurred after radiotherapy, ten patients were treated for the first time. 100 ml methylene blue was injected into the newly closed laryngopharyngeal cavity through the nasopharyngeal breather pipe for checking up whether it was watertight or not.</p><p><b>RESULTS</b>Among the sixteen patients, methylene blue leakage from the mucosal joint of the gular cavity closed by the stapler were not found in fifteen patients, it was only found in one patient. The transudatory places were sutured with absorbable Vicryl sutures. This patient healed well without pharyngocutaneous fistula. Negative surgical margins were achieved in all patients. No patient needed to be transferred to open surgery. Using a linear stapler device in total laryngectomy, 45 minutes could be saved as compaired to manual suture. One patient developed a light pharyngocutaneous fistula. The incidence of pharyngocutaneous fistula was 6.25% (1/16).</p><p><b>CONCLUSIONS</b>This stapled closed technique for pharyngoplasty is efficient, eliminates the risk of wound contamination, saves operation time and decreases the incidence of pharyngocutaneous fistula. This technique can be recommended as alternative for repairing the pharynx in patients undergoing total laryngectomy.</p>
