Laparoscopic First Hepatic Portal Blocking Device

Abstract

The invention relates to the technical field of medical instrument auxiliary equipment and especially relates to a laparoscopic first hepatic portal occlusion device. The device can limit the tensioning path of the blocking ring, prevent the surgical failure caused by the torsion, and improve the reliability of use. The blocking ring and the connecting plug are detachable for easy replacement andreduce the use limitations. The device comprises an outer sleeve, an inner sleeve, a connecting plug and a blocking ring; the device comprises a left upper top board, a left lower bottom board, a leftplacing block, a left screwed conduit, a left threaded rod, a left first pulley, a left second pulley, a left baffle plate, a right upper top board, a right lower bottom board, a right placing block,a right screwed conduit, a right threaded rod, a right first pulley, a right second pulley and a right baffle plate; the device also comprises a left locking bolt and a right locking bolt; a left side and a right side of the bottom of the connecting plug are provided with a left jack and a right jack; a left side and a right side of the front end of the connecting plug are respectively provided with a left screwed hole and a right screwed hole; the left screwed hole is connected with the left jack and the right screwed hole is connected with the right jack.

Description

technical field [0001] The invention relates to the technical field of medical device attachments, in particular to a laparoscopic first hepatic portal blocking device. Background technique [0002] As we all know, with the rapid development of laparoscopic hepatectomy in recent years, the application of hepatic portal blocking technology has become more and more important. The application of hepatic portal blocking technology has effectively reduced the amount of blood loss during laparoscopic liver resection. , reducing the chance of converting to laparotomy due to massive bleeding during the operation, the laparoscopic hepatic hilum blocking device is an accessory used for laparoscopic liver resection for intraoperative hemostasis in order to complete the operation more successfully device, which has been widely used in the field of medical treatment; the existing laparoscopic hilar blocking device includes an outer sleeve, an inner sleeve, a connecting plug and a blockin...

[0002] As we all know, with the rapid development of laparoscopic hepatectomy in recent years, the application of hepatic portal blocking technology has become more and more important. The application of hepatic portal blocking technology has effectively reduced the amount of blood loss during laparoscopic liver resection. , reducing the chance of converting to laparotomy due to massive bleeding during the operation, the laparoscopic hepatic hilum blocking device is an accessory used for laparoscopic liver resection for intraoperative hemostasis in order to complete the operation more successfully device, which has been widely used in the field of medical treatment; the existing laparoscopic hilar blocking device includes an outer sleeve, an inner sleeve, a connecting plug and a blocking ring, the outer sleeve is provided with a sliding cavity, and the inner sleeve The bottom end of the tube is inserted into the sliding cavity, and the inner sleeve is slidingly fitted with the sliding cavity, the top end of the connecting plug is connected to the bottom end of the inner sleeve, and the two ends of the blocking ring are respectively connected to the left and right sides of the bottom end of the connecting plug. The top of the inner cannula is provided with a pull ring; when the existing laparoscopic hilar blocking device is used, the blocking ring is first pushed out to the outer cannula through the inner cannula, and then the blocking ring is set in the place where the hepatic hilum blocking device needs to be blocked. Hemostasis liver surgery site, then pull the pull ring, pull the blocking ring to the bottom of the sliding cavity, and then tighten the blocking ring to stop bleeding; it is found in the use of the existing laparoscopic hepatic hilar blocking device that blocking The broken ring is thin, and when it is tightened, because the path is not fixed, it often twists, which affects the use and operation, and the reliability is low; and the blocking ring and the connecting plug are fixed and cannot be replaced, which limits the use higher
