This utility model relates to a kind of surgical operation assistive device, the otch location when specifically being applicable to abdominal operation.

Usually when implementing abdominal operation, adopt " S " type drag hook or abdominal cavity drag hook, need the doctor more than three to cooperate at least, labor intensity is big, influences operation technique.CN87206011U discloses the patent application that a kind of name is called " gallbladder self-retractor ", and its blade and connecting rod are and are wholely set, and component processing is made difficulty.Blade can not be replaced with the otch size, and the installation site is non-adjustable in the vertical, the top support width of cloth deficiency of otch.For operation brings certain influence.

The purpose of this utility model is further to provide to replace blade, also can guarantee that enough support width of cloth be arranged at otch top according to the operation needs with the otch actual size a kind of having.

This utility model has adopted following design, and drag hook comprises 5 blades and link rod thereof, and wherein the engagement of a side link rod and tooth bar is slided, and at the intermediary rack segments of left and right sides link rod, is connected with the link rod of being with blade by the shape nut of talking endlessly, as strutting top, abdominal cavity.One groove is arranged in the link rod, and link rod and tooth bar detachably use, and can do vertical or horizontal mobile adjustment.

Each blade and link rod adopt the securing member split to link, and design has vertical oval connection holes of major axis that is on the link rod, and blade can be done to replace or adjust or load and unload and use according to the operation needs.

Below in conjunction with accompanying drawing this utility model is further described.

Fig. 1 is an abdominal operation drag hook three-dimensional structure diagram.

Fig. 2 is upper abdominal surgery drag hook user mode figure.

Fig. 3 is hypogastric region surgery tractor user mode figure.

But Fig. 4 is Knock-Down Component figure.

(1) is the blade drag hook among the figure, (2) butterfly nut, and (3) (8) connecting rod, (4) (5) (6) (7) are blade, (9) rectangle tooth bar, (10) rotation rocking handle.

Lobus sinister sheet (4) is in relative position with lobus dexter sheet (7), the various blades that vary in size according to operation needs interchangeable, abundant exposure in order to the Rhizoma Atractylodis Macrocephalae open country, lower-left leaf (5) and right lower lobe (6) are in position side by side substantially, both have staggered slightly, so that self-retractor can overlap each other together when dwindling.Blade (4) (5) (6) (7) is interconnection respectively with connecting rod (3) (8), also can at any time remove out, blade drag hook (1) is connected in the medial launder of rectangle tooth bar (9), but move left and right, also can it be withdrawn at any time and install by spiral (2), the top that one end of rectangle tooth bar (9) passes connecting rod (8) and connecting rod (3) is slidingly connected, (10) be the rocking handle that is fixed on the connecting rod top end, rotation rocking handle (10) can make the movable displacement of left and right sides connecting rod, drive blade and adjust distance, Fig. 2,3 are respectively the drag hook schematic top plan view that is placed in the lower abdomen otch and has strutted.Fig. 4 is the STRUCTURE DECOMPOSITION figure of abdominal cavity self-retractor.Wherein (1A) is different with (1B) width, is applicable to glue portion operation up and down respectively.

Multi-functional abdominal cavity self-retractor belongs to special-purpose surgical operating instrument, because its distinctive medical treatment and sterilization requirement are arranged, so when the processing selection, must pass through electroplating processes with rustless steel or general medical steel, though this drag hook can be done size adjustment on the scope of strutting, but to notice that in processing and fabricating will there be suitable garden slippery at each straight flange angle, to avoid coup injury to abdominal visceral browser.
