Description

Hook for bladder operation

The operation on bladder drag hook.Belong to the medical surgical operating theater instruments.

All kinds ofly often need strut bladder cavity through operation on bladder.Clinically for fully having exposed surgical field of view in the bladder cavity, often need use 2～3 deep retractors simultaneously at present, strut bladder top rear wall and two side, take people's effort.The patent No. 91217251.7 provides a kind of medical operation drag hook, though can be laborsaving, can not reduce required drag hook quantity, drag hook handle end is fixed on the iron of operating-table by anchor clamps, puts, gets the drag hook inconvenience.Patent No. 92226225X provides a kind of abdominal operation self-retractor, and it is too many that it stretches into the bladder cavity intra vane, influences operation technique.In addition because bladder is a flesh cavity organ, neck of bladder, trigonum fixed-site, when using general surgery drag hook and above-mentioned two kinds of utility models, bladder muscle is shunk and is caused the slippage from the drag hook of Guang wall.

The purpose of this utility model provides a kind of easy to operate, and it is satisfied to expose bladder cavity, and wall of urinary bladder can not be from the operation on bladder drag hook of slippage downwards on the drag hook.

There is a steel wire elasticity folder top, the drag hook head of the present utility model back side, after the drag hook head stretches into bladder cavity, draws back steel wire elasticity folder, mentions bladder top rear wall in steel wire elasticity folder, slowly unclamps steel wire elasticity folder, promptly clamps wall of urinary bladder.With the drag hook head back side of steel wire elasticity folder corresponding position shallow band is arranged, increased frictional force, make slippage downwards of wall of urinary bladder.Respectively there is a distraction plate drag hook head of the present utility model both sides, and upper and lower two connect platelet, four dormant bolts, and each connects the platelet two ends respectively an aperture that matches with dormant bolt.Respectively there are two screws that match with dormant bolt distraction plate, drag hook head both sides, and dormant bolt is passed the aperture that connects platelet, screw in the screw of distraction plate, drag hook head both sides respectively, are about to distraction plate and drag hook head and couple together.According to the patient's bladder amount of capacity, the scope difference that surgical field of view need expose is launched distraction plate to drag hook head both sides, tighten dormant bolt, and distraction plate can not shrink because of bladder muscle and close up to the drag hook head.The bladder neck fixed-site, with this utility model to patient's cephalad direction tractive, promptly strutted bladder top rear wall, and distraction plate outwards struts the bladder two side, then surgical field of view exposes satisfied in the bladder cavity, 2～3 general surgery drag hook roles have been played, be rectangle than the long-pending little distraction plate of drag hook women's head-ornaments, its four angles are the lonely shape in garden, can not damage mucous membrane of urinary bladder, there is fixation hook at the handle rear of operation on bladder drag hook, and is laborsaving during it can help drag hook person's tractive, also can link to each other cancellation drag hook people with anesthesia frame on the operating-table simultaneously by aseptic binder and operating forceps.

The utility model has the advantages that easy to operately, strut that to expose in the bladder cavity surgical field of view satisfied, wall of urinary bladder can not be from slippage downwards on the drag hook head, and it is laborsaving to economize the people, makes simple.

Accompanying drawing 1 is an operation on bladder drag hook rearview.

Accompanying drawing 2 is operation on bladder drag hook side views.

Accompanying drawing 3 is operation on bladder drag hook front views.

This utility model is by the drag hook with drag hook head (1), drag hook handle (2), fixation hook (3); The steel wire elasticity folder (4) that feet (9) is arranged; Two distraction plates (6) have reached 4 connection platelets (7) of interconnect function, and 8 dormant bolt (8) three parts constitute.Steel wire elasticity folder welds by its feet and the drag hook head back side and in aggregates with drag hook head, drag hook handle, fixation hook.Each distraction plate is by 4 dormant bolts, and upper and lower two connect platelet and the flexible connection of drag hook head both sides, unscrew dormant bolt and are hinge shape, tighten dormant bolt and are the setting shape.

Bladder top otch generally is the stringer otch, and the distraction plate of operation on bladder drag hook is drawn close the drag hook head, stretches into together in the bladder cavity, handle turns to patient's cephalad direction, draw back steel wire elasticity folder, mention bladder top rear wall in steel wire elasticity folder, slowly unclamp steel wire elasticity folder and clamp wall of urinary bladder.According to patient's bladder amount of capacity and required exposure range difference, two distraction plates are outwards strutted to a certain degree, with screwdriver dormant bolt is tightened, to patient's cephalad direction tractive operation on bladder drag hook, surgical field of view exposes satisfied in the bladder cavity.Operating time is short, available hands tractive.Long as operating time, then be connected and fixed hook with aseptic binder one end, the other end is fixed on the anesthesia frame with operating forceps, economizes people, laborsaving, and operation can be carried out smoothly.In the time of need not exposing bladder cavity, unclamp steel wire elasticity folder, on carry the operation on bladder drag hook and can withdraw from bladder cavity.
