Abstract

A frame universal belly retractor belongs to surgery medical treatment apparatus, which comprises a pillar, a cross beam and a pull hook. The utility model is characterized in that the cross beam is rectangle gear rack shaped with two slide seats. Rotate the crank handle of the slide seat to make the transmission wheel in the slide seat move upwards along the teeth of the cross beam. On the occasion that the two slide seats slowly move in opposite directions, the pull hook connecting with the suspension hook of the slide seat moves forward retracts the abdominal incision. The utility model has the advantages that it can voluntarily accommodate the size and direction of the sight of the surgery and exposed completely the retracted sight of the surgery up to the hilt and reduce unnecessary surgery wound.

Description

The omnipotent abdominal retractor of frame-type

This utility model relates to the omnipotent abdominal retractor of a kind of frame-type, belongs to surgical operating instrument.

In the surgical operation, the exposure of abdominal operation open country is often used operation retractor or drag hook with the manpower traction, this traditional manpower traction's method exists pulling force deficiency, easily slippage, can not continue to be fixed in desired location, manpower traction's fatiguability, art are wild exposes bad and then cause shortcoming such as postoperative complication.In order to address the above problem, Wang Xuehao etc. rolled up the article of having delivered " adjustable frame-type abdominal cavity retractor is in the application of abdominal surgery " on the 1st phase " Nanjing Medical College's journal " at 1988 the 8th, narrated in this article by strut, cross bar, about the abdominal cavity retractor that the drag hook of actuator and different size is formed can advance according to the needs of operating field, front and back, the degree of tightness fine setting of multidirectional adjusting in the left and right sides and drag hook, a kind of retractor of clear operating field well is provided, but, the connection part of said frame drag hook is screw and fixes, and its strut and crossbeam can not voluntary activities and use very inconvenience; Retract operating field and be to draw back again with drag hook earlier and be fixed on the framework, so the exposure of operating field is difficult to choose at random, also can cause patient posture moving influence operation process when affecting; Its dynamics that retracts is subjected to the restriction of manpower size.

The purpose of this utility model is to avoid the above-mentioned weak point of prior art, but and a kind of regulated at will operating field size and all directions are provided, reduce unnecessary operation wound, the omnipotent abdominal retractor of frame-type accurately easy to use.

The purpose of this utility model reaches by following technical measures.

This utility model includes two columns, and crossbeam and drag hook are formed, and drag hook is provided with locating hole, pin joint one coupling block on locating hole, and an end of two coupling bars is provided with connecting hole, the both sides pivot joint of its other end and coupling block.Crossbeam is a rectangular teeth strip crossbeam, be set with on the crossbeam respectively with two slides (6 and 9) of linking up with, the hook of slide (6 and 9) and the connecting hole clasp joint on the drag hook coupling bar, two root posts are rectangle, its lower end is a tooth bar shape, on the profile of tooth section of two columns, be respectively installed with slide (15 and 13), column (4) top installs a groove, the top of column (12) is provided with elbow, one end of crossbeam places the groove of column (4), and its other end is affixed with the elbow of the adapter sleeve of being with holding screw and column (12).

Be provided with drive in two slides on two slides on the crossbeam and two columns, this drive is made up of with two cylinders that are connected two disks two disks, a tooth of tooth bar shape crossbeam places between two cylinders, be fixed with connecting rod on the drive and pass slide (6,9,15 and 13) affixed with crank, two slides (15 and 13) are fixed on the berth, fix it with the holding screw of slide (13).

Rotation to the left or to the right along with the crank on the crossbeam slide, the drive that fuses with crank rotates to the left or to the right, two cylinders in the drive roll along tooth left or right on the tooth bar shape crossbeam, make slide (6 and 9) or move right left, the drag hook that is connected with hook on the slide advances thereupon or retreats, reach the purpose that retracts the abdominal cavity otch, the position of regulating two root post upper saddles (15 and 13) reaches the purpose that drag hook rises or falls.

This utility model compared with prior art has following advantage: this utility model draws back operating field lentamente by drive, size and Orientation that can the regulated at will operating field, reduce unnecessary operation wound, be applicable to the patient that xiphoid angles is little, easy to use, 30 routine operation on liver have successively been carried out, 20 routine cardia total gastrectomy operation and 17 routine operation on spleen, none example causes complication because of this apparatus, especially complete because of using this utility model that operating field is exposed in operation on liver, avoid hepatic portal occlusion commonly used, this patient to hepatic insufficiency is undoubtedly a Gospel.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the drive structural representation.
