Abstract
The utility model relates to an automatic medical retractor for surgical operations, and is characterized in that a vertical bar is fixed on an operating table by a clamping device a, a cross bar and the vertical bar are fixed by a clamping device b, a rocking-bar moving device a is connected with the cross bar by a clamping device c, a rack a sequentially passes through a rocking-bar moving device b and the rocking-bar moving device a and is meshed with gears in the rocking-bar moving devices a and b, a rocking-bar moving device c is movably connected with the rocking-bar moving device b by a connecting shaft a, a rack b passes through the rocking-bar moving device c and is meshed with a gear in the rocking-bar moving device c, and the retractor is arranged at the lower end of the rack b; and a ratchet bar is movably connected with the rocking-bar moving device c by a connecting shaft b, a wedge block is arranged on the rocking-bar moving device b, one end of a reed is connected with the rocking-bar moving device c, and the other end of the reed is propped against the ratchet bar, so that the ratchet bar is propped against the wedge block so as to form a brake apparatus. The automatic medical retractor provided by the invention simulates the movement effect of an arm, so that the retractor can be pitched at any angle within a surgery-acceptable range and pulled in any direction so as to meet intraoperative individual needs.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of medical self-retractor.
Background technology
The patient needs the assistant that tissue is drawn back according to certain level in operation process; And then the operation that undergos surgery; If it is improper that the assistant draws back level, direction, the strength of tissue, the patient just can't carry out normal operation technique, even can bring unnecessary trouble.
Summary of the invention
This utility model provides a kind of medical self-retractor for overcoming the problems referred to above, and the movement effects of anthropomorphic dummy's arm is operated by the patient; Replace the assistant to draw back tissue; Not only save manpower, and can patient's ability be performed to ultimate attainmently, reach best surgical effect.
The purpose of this utility model can realize through following technical scheme:
This utility model is made up of montant, cross bar, clamping device a, clamping device b, clamping device c, rocking bar mobile device a, rocking bar mobile device b, rocking bar mobile device c, tooth bar a, tooth bar b, drag hook, ratchet bar, connecting axle a, connecting axle b, reed, voussoir.Montant is fixed on the operation table through clamping device a; Cross bar is fixed on the montant through clamping device b; Rocking bar mobile device a is connected on the cross bar through clamping device c, and tooth bar a passes rocking bar mobile device b, rocking bar mobile device a successively, and with rocking bar mobile device b, rocking bar mobile device a in gear mesh; Rocking bar mobile device c flexibly connects through connecting axle a and rocking bar mobile device b; Tooth bar b passes rocking bar mobile device c, and with rocking bar mobile device c in gear mesh, drag hook is installed in the lower end of tooth bar b.The arrestment mechanism of being made up of ratchet bar, connecting axle b, reed, voussoir is set between rocking bar mobile device b and rocking bar mobile device c; Ratchet bar flexibly connects through connecting axle b and rocking bar mobile device c; Voussoir is installed on the rocking bar mobile device b; Reed one end is connected with rocking bar mobile device c, and the other end is against on the ratchet bar, makes ratchet bar withstand voussoir.
The beneficial effect of this utility model is:
The movement effects of anthropomorphic dummy's arm makes drag hook to any direction tractive, not only save manpower with arbitrarily angled pitching in the operation allowed band, can also adapt to individuation demand in the art.
Description of drawings
Fig. 1 this utility model structural representation
Fig. 2 arrestment mechanism structural representation
Labelling is following among the figure: montant 1, cross bar 2, clamping device a 3, clamping device b 4, clamping device c 5, rocking bar mobile device a 6, rocking bar mobile device b 7, rocking bar mobile device c 8, tooth bar a 9, tooth bar b 10, drag hook 11, ratchet bar 12, connecting axle a 13, connecting axle b 14, reed 15, voussoir 16.
The specific embodiment
Like Fig. 1, shown in 2, a kind of medical self-retractor of this utility model is made up of montant 1, cross bar 2, clamping device a 3, clamping device b 4, clamping device c 5, rocking bar mobile device a 6, rocking bar mobile device b 7, rocking bar mobile device c 8, tooth bar a 9, tooth bar b 10, drag hook 11, ratchet bar 12, connecting axle a 13, connecting axle b 14, reed 15, voussoir 16.
With the cleaning of breast carcinoma improvement radical correction axillary fossa is example, and the montant 1 of the self-retractor that assembles is fixed on the operation table, through clamping device a 3 at this moment; Cross bar 2 is fixing with montant 1 through clamping device b 4, slip rocking bar mobile device a 6 on cross bar 2, and a 6 adjusts to suitable position and angle according to patient's custom with slip rocking bar mobile device; Be fixed on rocking bar mobile device a 6 on the cross bar 2 through clamping device c 5; Optionally shake the rocking bar on rocking bar mobile device a 6, rocking bar mobile device b 7, the rocking bar mobile device c 8 according to personal habits, tooth bar a 9, tooth bar b 10 are stretched, drag hook 11 is hooked the large and small flesh of breast; Move ratchet bar 12; Make it to separate, optionally shake the rocking bar on rocking bar mobile device a 6, rocking bar mobile device b 7, the rocking bar mobile device c 8 according to personal habits once more, tooth bar a 9, tooth bar b 10 are stretched with voussoir 16; Drag hook 11 is adjusted to suitable position and luffing angle; Unclamp ratchet bar 12, make it withstanding on the voussoir 16 under the promotion of reed 15, prevent that drag hook 11 from being pushed open by the active force that muscle applies.
