Description
The present invention relates to a kind of abdominal operation drag hook apparatus, is a kind ofly can replace that the people draws, as to be used for abdominal operation drag hook apparatus.Be adapted to the various operations of abdominal part.
Existing large, medium and small right-angle retractor or large, medium and small serpentine drag hook all must the people during operation be held the drag hook handle and are carried out internal organs and draw back, and this is artificial drag hook.The drag hook of using in the drag hook of selling on the market and each the hospital's abdominal operation all belongs to the above-mentioned type now.Consult " medical apparatus and instruments figure originally " the 3rd, the 4th of publishing in medication purchasing supply station, Shanghai in 1974, the surgery tractor apparatus of " medical apparatus and instruments new product " publication of Ministry of Health of the People's Republic of China's publication in 1976 all belongs to the above-mentioned type." medical apparatus and instruments " bimonthly of consulting-nineteen ninety in 1979 Shanghai Medical Appliances Inst's publication amounts to the operating theater instruments that 11 volumes, 66 periodicals are stepped on, and does not find abdominal operation unmanned drag hook class technology and product." Chinese patent index " since on April 1st, 1985, Patent Law was implemented retrieved, and retrieval A61B00/00, B22, B30 have not found abdominal operation unmanned drag hook class technology and product.
The purpose of this invention is to provide the drag hook apparatus that a kind of people of replacement draws, and will satisfy the various operation needs of abdominal part.
The unmanned drag hook part of abdominal operation with rustless steel or nontoxic heatproof plastics or the ordinary steel chromium plating more than 125 ℃ be processed into.The unmanned drag hook of abdominal operation by slide rail, slide block, decide arm, cursor slide, stay hook, " ∩ " type support and link four apparatuses (seeing Figure of description one, two, three) that need the drag hook of position adjustable, length to constitute by operation with screw.Be located at the stay hook of deciding on arm, the cursor slide during use and entangle the otch both sides, strut operative incision, sliding sleeve is locked voluntarily.Decide arm, cursor slide and connect " ∩ " type support with screw.Deciding to connect upward drag hook with expansion screw on arm, cursor slide, slide block, " ∩ " type support, by the position that needs drag hook, the length direction of operation, only need corresponding each screw of degree of tightness just can adjust, expose operative site, operation can be carried out.If undergo surgery again after the drag hook when making the gallbladder enucleation on " ∩ " type support changes the liver hook into.
Bring into use the unmanned drag hook of abdominal operation 2 years so far from March, 89, in 16 routine abdominal operations, use this apparatus.The unmanned drag hook of abdominal operation relatively has following advantage with existing various drag hooks: 1. every operation can reduce by two assistants; 2. can be by lasting, the stable operative site organs and tissues in addition that draws back of the needs of operation, operative site exposes; 3. operative speed is accelerated, and every operation reduces 30-60 minute; 4. the dark more superiority that demonstrates this apparatus more of operative site makes the operation of difficulty become the operation of easily doing, and adapts to all kinds of hospitals at different levels, especially adapt to basic hospital just, intermediate surgeon carries out surgical work; 5. routine encases the drag hook body with gauze pad, and drag hook does not directly contact and drawn internal organs or tissue, and the pulling force appropriateness can not cause visceral organ injury, tissue compressing necrosis; 6. this drag hook is made easily, cost is low, easy to use.
The shortcoming of artificial drag hook apparatus: not only increase assistant's number, the people has drawn for a long time fatiguability.Pulling force is at times strong and at other times weak, and little when big during operative region, the organs and tissues that is drawn pours in operative region often, and operative site exposes bad, causes the operation difficulty.The assistant crowds in operating-table more, hinders the operation of operator and chief second, and operative speed is slow.
The unmanned drag hook installation diagram of accompanying drawing 1 abdominal operation.
Accompanying drawing 2 drag hooks (20) A is to view.
Accompanying drawing 3 liver hook (10) B are to view.
With reference to the unmanned drag hook of Fig. 1 abdominal operation by slide rail (1), (2), decide arm (22), cursor slide (3), " ∩ " type support (12) and the drag hook (20), (16), (17) and the liver hook (10) that are contained in respectively on the above-mentioned part with screw constitute.Article two, parallel slide rail (1), (2) left end with identical two sunk screws (21) with decide arm (22) and link and fix.Right-hand member and end block (5) link fixing.Slide block (6), cursor slide (3) can be gone up move left and right in slide rail (1), (2).Decide to establish identical stay hook (9) respectively below arm (22), the cursor slide (3).Strut behind the operative incision locking voluntarily that puts in place of the sliding sleeve (4) on the cursor slide (3).Decide to establish screw (18), (19) respectively above arm (22), the cursor slide (3), the two ends, the left and right sides of " ∩ " type support (12) are enclosed within respectively on screw (18), (19).Screw (18), (19) are passed cylindrical void binding in drag hook (16), (17) handle more respectively." ∩ " type support (12) by about two constitute, screw (14) links, about two can be around screw (14) rotation, the folding of " ∩ " type support with cursor slide (3) move left and right.
Constitute by drag hook handle (24), upper body (8), lower body (7) with reference to Fig. 1, Fig. 2 drag hook (20).The stringer cylindrical void that the screw (23) of slide block (6) passes on the drag hook handle (24) links, and drag hook (20) can vertically move forward and backward and with the slide block move left and right, putting in place screws screw.The cylindrical void (27) that the screw (28) of drag hook handle (24) turning end passes drag hook upper body (8) links, and drag hook upper body (8) can parallelly move, and around screw (28) rotation, putting in place screws screw.Drag hook lower body (7) is inserted in drag hook upper body (8), and the screw of drag hook lower body (26) passes the interior cylindrical void in upper body (8) (25), and lower body (7) can slide up and down, and needs to adjust length by operation.Then screw (26) is screwed.Drag hook (16), (17) belong to the homotype drag hook with drag hook (20).
Constitute by the liver neck of hook (13), spill spin block (11), liver coupler body (31) with reference to Fig. 1, Fig. 3 liver hook (10).Screw (14) on " ∩ " type support (12) passes the liver neck of hook (13) stringer cylindrical void, and liver hook (10) can vertically move forward and backward, and around screw (14) rotation, putting in place screws screw (14).The liver neck of hook (13) front end screw is enclosed within the screw (34) of spill spin block (11) and goes up binding, and the screw (32) on the spill spin block (11) passes liver coupler body (31) upper end arc slot (33) and links.Liver hook (10) but move left and right around screw (32) rotation, around the rotation of screw (34) axle, screws respective screws after putting in place.As make the gallbladder enucleation, no matter which kind of position gallbladder is, liver hook (10) can both adapt to.Gallbladder is hauled out " ∩ " die cavity (30) in the liver hook and is undergone surgery.
The unmanned drag hook apparatus of abdominal operation is adapted to operations such as liver, gallbladder, stomach, pancreas, spleen, intestinal, nethike embrane, kidney, bladder, uterus, ovary, adnexa, vermiform appendix.Especially adapt to the dark difficulty operation in position as gallbladder enucleation, bile duct exploration art.
