This utility model to achieve these goals, adopts following technical scheme: a kind of hourglass shape laparoscopic cannula of and cut sealing matched with devices band adjusting rod is by casing cover, cover neck, sealing cap, spring assembly, adjusting rod, the first diaphragm seal, the second diaphragm seal, screw thread, hourglass shape pipeline upper body, hourglass shape pipeline lower body, rubber seal ring, connecting platform, base plate, inner tube forms; Between hourglass shape pipeline upper body and hourglass shape pipeline lower body, rubber seal ring is set, top, hourglass shape pipeline upper body arranges casing cover, casing cover one side arranges adjusting device, casing cover top arranges cover neck, on cover neck, sealing cap is set, hourglass shape pipeline lower body below arranges base plate, and base plate center arranges circular hole, and the corresponding circular hole of base plate one side arranges inner tube.
On the outer wall of above and below, hourglass shape pipeline upper body, screw thread is respectively set, hourglass shape pipeline lower body upper inner wall arranges connecting platform, the middle part of connecting platform is tubular conduit, tubular conduit inwall arranges screw thread, connecting platform below one side arranges spring assembly, and the tubular conduit of the corresponding connecting platform of spring assembly one side arranges the second diaphragm seal; The screw thread of below, hourglass shape pipeline upper body and corresponding being spirally connected of screw thread in hourglass shape pipeline lower body connecting platform, rubber seal ring is fixed in the waist of the hourglass shape pipeline after connection.
Described adjusting device is by adjusting rod, spring assembly, and the first diaphragm seal forms; Spring assembly is set in casing cover, and the corresponding spring assembly in cover neck below arranges the first diaphragm seal, and casing cover one side arranges adjusting rod, and adjusting rod one end is by the preformed hole setting corresponding to spring assembly of casing cover; The inwall of casing cover arranges screw thread, casing cover and corresponding being spirally connected in hourglass shape pipeline upper body.
The second diaphragm seal, base plate, inner tube are dismantled or are installed according to action need.
Utility model beneficial effect: when this utility model and peritoneoscope auxiliary incision sealing device are used in conjunction with, hourglass shape peritoneoscope pipeline is strained and fixed by the double-layer elastic film of peritoneoscope auxiliary incision sealing device, sealing effectiveness ideal, celioscope operating apparatus is entered to hourglass shape laparoscopic cannula and continued operation, make doctor more convenient to operate in operation process, improve operation efficiency, alleviate the labor intensity of surgical doctor, reduce patient suffering, for each patient has saved huge medical expense.
Unique hourglass shape design, fixedly secures the double-layer elastic film of peritoneoscope auxiliary incision sealing device and hourglass shape laparoscopic cannula, and the waist of hourglass shape laparoscopic cannula designs the realization of better fitting of unique rubber seal ring and elastic membrane and seals.
Double density mounting is realized the excellent sealing of hourglass shape laparoscopic cannula, sealing dual fail-safe in realizing.
Casing cover and base plate, detachable with the main body of hourglass shape laparoscopic cannula, realize the scalable of the inner structure length in this device abdominal cavity, while facilitating the low and inner narrow space in abdominal cavity of pneumoperitoneum pressure, operate.
Adjusting rod can be controlled opening and closure of diaphragm seal, when can playing fixation to the laparoscopic instrument entering, has protected again the surface of expensive laparoscopic instrument not to be scratched.
Simple in structure, manufacture easily, easy to use, economic and practical, handling safety, is convenient to promote, and volume is little, is easy to carry and transports; Can realize not damaged and close interim otch, time saving and energy saving, sealing effectiveness ideal, good operation effect, alleviates patient suffering, reduces patient treatment expense, makes patient's rehabilitation as early as possible, can promote the use of.
