Abstract

The utility model relates to a medical 3-D semi-automatic operation pulling hook, which belongs to the technical field of medical operation instruments. The medical 3-D semi-automatic operating pulling hook is composed of a semi-automatic retractor, an adjustable plate, a hinge plate, an adjustable right-angle pulling hook and a light source. The semi-automatic retractor comprises two head parts, two handle parts, a central shaft and a one-way tooth sluice. The adjustable plate comprises a core plate and a movable plate, and one end of the core plate is vertically welded to one head part of the retractor. The movable plate is sheathed outside the core plate and can be slid on the core plate. The hinge plate comprises a fixed hinge and a movable hinge, and two hinges are connected like a hinge type. One end of the fixed hinge is vertically welded to the other head part of the retractor. The lower part of each hinge is provided with a structure which is similar to the slid movable plate of the adjustable plate. The hook end of the adjustable right-angle pulling hook is provided with the movable plate which is slid and the upper part of the hook end is provided with the light source. Handle ends are provided with a side groove, and the handles are inserted below a cap of the central shaft of the semi-automatic retractor to be fixed. The utility model has the advantages of three dimensional adjustability of the adjustable right-angle pulling hook, smooth contact surface, not damage of tissues, stableness after being adjusted in the operation and good illumination of the light source in the operation area, and one to two manpower pulling hooks can be saved, and thus the utility model is especially suitable for operations of small incisions of deep parts.

Description

The semi-automatic operation drag hook of medical three-dimensional

This utility model is the semi-automatic operation drag hook of medical three-dimensional, belongs to medical apparatus and instruments, is specially adapted to the exposure of deep small incision surgery.

Present surgery tractor generally is a 1-2 direction, and the drag hook degree of depth is non-adjustable, and the drag hook size is fixing, is difficult to adapt to the different otch that change.Operation process often needs 1-2 special messenger's drag hook to help the patient.The someone has developed wire-like depth-adjustment drag hook recently, and drawing back tissue does not have slick contact surface, does not have three-dimensional adjustability, is not with light source, can not satisfy the needs of the less incision surgery in deep.It is not good to still have the art district to expose, and uses inconvenience, takes manpower, and the illumination of art district is not enough, easily increases the shortcoming of damaging.

The purpose of this utility model is to overcome weak point in the above-mentioned prior art, in horizontal 4 directions shiny surface is arranged by 1 drag hook and provide a kind of, and the depth is adjustable, the band light source, and once adjustment reaches intact exposure, three-dimensional semi-automatic operation drag hook reliable and stable, not damaged tissue.

The purpose of this utility model realizes by following measure:

This utility model is made up of semi-automatic retractor, adjustable plate, loose-leaf board, adjustable right-angle retractor, light source.Semi-automatic retractor comprises 2 heads, 2 shanks, central shaft, unidirectional tooth lock, adjustable plate comprises central layer, moving plate, central layer one end is vertically welded in a head of retractor, moving sleeve-board slides outside central layer and on central layer, loose-leaf board comprises fixed page or leaf, moving page or leaf, two pages of seemingly folding sample connections, fixed page or leaf one end vertical welding is connected to another head of retractor, and the moving plate structure like the slip in the adjustable plate is all arranged at the bottom of each page.Adjustable right-angle retractor, comprise right-angle retractor, moving plate, right-angle retractor is divided into drag hook end, pommel, pommel has 4 side channels, insert by groove under the medicated cap of central shaft of semi-automatic retractor, moving plate slides at the drag hook end, and there are miniature bulb or fiber optic source cementation in the drag hook end top of right-angle retractor, and light source can be made up of miniature bulb, lead-in wire, power supply or fiber optic source, light beam, luminous source.

Fig. 1 is total figure of the present utility model.

The utility model is described in further detail:

semi-automatic retractor head

2,6 central shafts 16, handle 15,19, unidirectional tooth lock 17 below in conjunction with embodiment and accompanying drawing.One end of the central layer 1 of adjustable plate is vertically welded on 2, and the moving plate 3 of adjustable plate is enclosed within on the central layer 1 and slides, central layer head broadening 1mm, and moving plate afterbody constriction 1mm slides and not separated both, and moving wrench has 2 apertures, 4 about diameter 1mm, helps cleaning and sterilizing.Fixed page or leaf 5 upper ends of loose-leaf board are vertically welded on 6, and the fixed page or leaf 5 of loose-leaf board is connected with moving page or leaf 7 similar folding papers, and certain tension force is arranged, and two pages of bottoms are with the moving plate that moves

plate

8,9 similar adjustable plates respectively and can slide up and down.The drag hook end 10 of adjustable right-angle retractor is with moving plate 12 and slides, and the neck of hook 13 has 4 side channels 14, and an optional in use groove inserts in the medicated cap of retractor central shaft 16 and fixes down.Bulb or fiber optic the source nontoxic and warm glue bond of 11 usefulness give the top of the drag hook end 10 of adjustable right-angle retractor, and the lead-in wire or the fiber optics other end that connect bulb light source 11 have plug 18, and plug connects existing 3v power supply or luminous source outlet.

During use, each moving plate is drop-down, loose-

leaf board

5,7 closures, before push away the unidirectional tooth lock 17 of semi-automatic drag hook after, make

retractor

2,6 closures, with adjustable plate, loose-leaf board is put into otch, automatically being transferred to each moving plate of pressure needs length, make 2 after the handle 15 pressurization closures, 5 wound pulled apart, unidirectional tooth lock do not bounce back after keeping drawing back, draw back otch after, push away loose-leaf board 7 and open 90 degree, do not bounce back because tension force is arranged, the moving plate 12 of adjustable right-angle retractor is drop-down, puts into and draw back surrounding tissue along loose-leaf board 7, central shaft 16 medicated caps of selecting neck of hook side channel 14 suitable positions to insert retractor are as required fixed down, light source line plug 18 connects 3v power supply or the outlet of fiber optics plug sending and receiving light source, and bulb or light source head 11 are luminous, know the art district with abundant exposure.

Implement and clinic trial by animal, respond well.
