Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of lacunula endoscopic surgery drag hook.
Background technology
Endoscopic surgery technology obtains tremendous development at chest and abdominal surgery field, but just at the early-stage in the research of non-natural lacuna endoscopic technic, such as arthroscope, newborn chamber mirror, Endoscopic Thyroidectomy.Lacunula endoscopic surgery is developed so far, and operation pathway change is various, and for Endoscopic Thyroidectomy, the path according to operation can be divided into the little cicatrix Endoscopic Thyroidectomy of cervical region and cervical region without cicatrix Endoscopic Thyroidectomy; Complete Endoscopic Thyroidectomy (total endoscopicapproaches) and scope is divided into assist thyroid operation (video assissted endoscopic approahes) according to modus operandi.Scope operation on neck requires that operation is meticulous, particularly prevent recurrent laryngeal nerve, superior laryngeal nerve, parathyroid gland, cervical region Major Vessels and neural place equivalent damage, from initial breastbone upper cut pathway develop gradually become reach cosmetic result, cervical region No-scar surgery pathway cicatrix moved to neck, the foundation of its working place and maintenance, and how to keep the clear visual field in operation technique space most important for the success or not of operation.
Electric knife and ultrasound knife are apparatuses conventional in endoscope-assistant surgery, but when being separated, cutting and organizing, easy generation vaporization water smoke, smog etc., the mirror visual field, obvious interference chamber, now, patient can only introduce suction pump and aspirate, or suspends operation, opening puncture casing makes chamber air circulate, until visual area recovers clear.Further, for all lacunula endoscopic surgeries, apparatus is many in fan-shaped concentrated area, not only be unprofitable to operation, and " chopsticks interference " effect can be there is, be namely difficult to multi-faceted harmonious in small space, and change the fluency that apparatus can affect operation continually.Therefore, the inexorable trend that " a tool multipotency " is the development of lacunula endoscopic surgery is realized.
Application number is " 200420052593.8 ", Authorization Notice No. is " CN 2745517 Y ", name is called that the Chinese utility model patent of " cavity mirror thyroid operation retractor " discloses a kind of cavity mirror thyroid operation retractor, described cavity mirror thyroid operation retractor is formed through bending process by tinsel, drag hook body is " V " font at the wide end, the front end of drag hook body is needle point, the near wide bottom of drag hook body both arms is to bending about 150 ° of angles, direction of drag hook bar, the plane of drag hook body and drag hook bar are 90 ° of angular distortions, and drag hook handle is arc.In use, thrust with the skin of needle point outside cervical region of drag hook, then through over-rotation drag hook, whole drag hook is inserted thyroid intracavity, under the assistance of chamber mirror elastic separating plier, with the coupler body of drag hook, the Anterior jugular muscles separated is pulled to outside, reach and expose thyroid object.In this utility model, the top of drag hook body is sharp keen needle point, after entering intracavity, there is the potential risk puncturing carotid arteries when adjusting drag hook position; This drag hook only can realize the function setting up and maintain cavity space, and functionality is little.
Application number is " 200920050459.7 ", Authorization Notice No. is " CN 201346219 Y ", name is called that the Chinese utility model patent of " cavity mirror thyroid operation retractor and auxiliary puncture guide " discloses a kind of cavity mirror thyroid operation retractor and auxiliary puncture guide, be made up of three-piece, there is handle one end, described auxiliary puncture guide is pipe body, front end is the hollow needle point of cutting, cavity mirror thyroid operation retractor is elongated filament, and front end is " V " font drag hook.During operation, determine the site of puncture that needs operate, with puncture guide hollow needle point in site of puncture slowly inserting needle penetrate skin, subcutaneous tissue comes into view under endoscopic views, escape leading device hollow needle point is a little, make a guide hollow needle point part stay in body, a part expose to body surface formed one by guide hollow needle point produce connection body surface and body in passage; Drag hook main body being rotated counterclockwise along passage enters in body, escape leading device; The muscle group in throat can be pulled to outside by the drag hook entered in body, and thyroid is fully exposed; Unclamp the tissue that drag hook draws after art finishes, the angle along coupler body front end produces clockwise.The venipuncture difficulty of this utility model patent is large, it is high to require, large to the requirement of strength of " V " font drag hook, the dynamics difficulty of control is grasped, and puncture guide only can realize setting up this simple function of cavity space, and functionality is little.
