Abstract
The utility model relates to an automatic surgical retractor which is characterized in that a pillar bracket is in a sleeve type and is provided with a rack bar, a gear wheel and a crank handle, all of which are used for lift, expansion and contraction. The lower end of the pillar bracket is provided with vertical and horizontal screw holes and screws used for screwing down the pillar bracket. A bent beam provided with a horizontal rotating shaft on which the end of a steel cable and a ratchet wheel are fixed is connected to the upper part of the pillar bracket, and the end of the rotating shaft is connected with a rotary handle. The steel cable is connected with a hook via a pulley. The utility model has the advantages of simple structure, convenient installation, easy operation and portability. The utility model enables the operating field to expose thoroughly, and the utility model is suitable for operations that are cut into belly through an inclined cut at the rib edge but do not need thoracotomy, such as epigastrium operations on liver, gallbladder, spleen, etc.
Description
This utility model belongs to surgery and expands the wound apparatus, the operation retractor tool of expansion wound during particularly a kind of surgery liver and gall operation on pancreas.
At present, during surgery liver and gall operation on pancreas, expose thoroughly, often need to adopt manual drag hook, the costal margin angular cut is retracted in order to make operating field.Because operating time is longer, manual drag hook retracts process, medical personnel's fatigue, to operation carry out smoothly have unfavorablely more, do not have suitable mechanical type drag hook again.
The purpose of this utility model is, designs and produces a kind of automatic operation retractor, adopts to be fixed on rotating shaft and the pulley that is provided with on the support of operating-table side, retracts with hook with drive, realizes the expansion wound of operative incision is retracted, and is convenient to medical personnel and undergos surgery.
Automatic operation retractor of the present utility model is made up of support, rotating shaft, hook, it is characterized in that, the column support is telescopic, is provided with lift telescopic with tooth bar, gear and crank, is provided with the fixing pin of using on the column support; Column support lower end is provided with vertical screw and screws with screw and level to screw and screw and use screw; Column support upper end is connected with camber beam, is provided with feathering axis on camber beam, is fixed with steel wire rope termination and ratchet on the rotating shaft, and the rotating shaft termination is connected with turning handle; Steel wire rope is connected with hook by pulley.
Using method of the present utility model is, operation retractor column support lower end is clamped in the operating-table side, utilizes tooth bar, gear to adjust the suitable height of column support, and use dowel fixes; Hook is hooked on retracting on the position of operative incision, rotates the handle at camber beam place, rotating shaft and ratchet rotation process, wire rope roll on runner, is lifted to the height that needs by pulley with hook, and the ratchet card can block ratchet, fix rotating shaft simultaneously, can begin operation.After operation, only need unclamp the ratchet card, rotating shaft and ratchet get final product reverse rotation and unclamp steel wire rope, throw off the hook position.
The utility model has the advantages that simple in structure, easy for installation, processing ease is easy to carry.Operating field is exposed thoroughly.Be applicable to the costal margin angular cut and advance abdomen, need not open the upper abdominal surgery of breast again, as hepatectomy, biliary tract, spleen, stomach cardia, portal hypertension, adrenal gland's operation.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of automatic operation retractor
Fig. 2 is A-A profile of Fig. 1
Fig. 3 is the user mode figure of automatic operation retractor
