Position is adjusted the height of device when in use to change the height of fixed plate, the back stay on right side and preceding branch
Control seat 9 is equipped on the right side of the left side of bar and the back stay in left side and front support rod, there are four control seat is set, for leading
The position of corbel back slab is adjusted, and front and back is symmetrically cased with adjusting set 10 respectively on the back stay and front support rod, and adjusting set can be in I
It is moved forward and backward, the position of control seat can be adjusted on back stay and front support rod, the top of the adjusting set, which is equipped with, to be adjusted
Adjusting set can be fixed on back stay or front support rod by screwing adjusting bolt, adjusting set is fixed, is kept away by bolt 11
Exempting from device, position is moved during use, the right side of the adjusting set of the left end and left side of the adjusting set on right side
End is equipped with fixing head 12, and fixing head is used to limit one end of control-rod, is hinged with the one of control-rod 13 in the fixing head
End, one end of control-rod can rotate in fixing head, the other end of the control-rod with control that seat is hinged, control-rod it is another
End rotates in control seat, and two control-rods link together a control seat with two adjusting sets, and adjusting set is in front support rod
Or the movement on back stay can drive control seat mobile, to the front-rear position of control seat be adjusted, and front and back
Triangle is formed between strut and control-rod can more effectively support control seat, avoid the position that seat is controlled during operation
Movement is set, top of the control seat or so can be moved left and right through towing plate 14, towing plate is equipped in control seat, thus
The left-right position of traction drag hook is adjusted, the front side wall of the towing plate is equipped with the first rack gear 15, after the towing plate
Side wall is equipped with the second rack gear 16, and the first rack gear with the second rack gear is used to that the position of towing plate is adjusted, the control seat
Top before and after be respectively equipped with before adjust head 17 and it is rear adjust head 18, preceding adjustings head and rear adjusting head are rotated for medical staff
It adjusts, the preceding lower end for adjusting head and adjusting head afterwards is respectively equipped with preceding adjustment gear 19 and rear adjustment gear, before rotation
Adjusting head and the rear head that adjusts can drive preceding adjustment gear and rear adjustment gear to rotate, and the preceding adjustment gear is nibbled with the first rack gear
Transmission is closed, the rear adjustment gear and the second rack gear engaged transmission, the rotation of preceding adjustment gear and rear adjustment gear pass through respectively
On first rack gear and the second rack-driving to towing plate, make towing plate to the left or move right, the towing plate is close to fixed
One end of bar is equipped with traction drag hook 20, and traction drag hook is bent downwardly, for pulling open the tissue retraction of patient, affected part is exposed
Come, in order to which doctor performs the operation, one end of the towing plate and traction drag hook upside be equipped with draw bolt 21, draw spiral shell
Bolt will draw drag hook between being used for and be fixed on towing plate, and when needing to replace traction drag hook, unscrewing draw bolt will be drawn
Drag hook removes the traction drag hook more renewed, and traction drag hook is fixed again by precession draw bolt.
Specifically, the traction drag hook is made of stainless steel material, the surface Glabrous thorn of stainless steel material is being drawn
Will not be to patient's additional injury again when the affected part of patient being taken to organize, while stainless steel material is corrosion-resistant and is not likely to produce shape
Become, is also convenient for the cleaning that carries out disinfection to it.
Specifically, the lower end of the adjusting bolt and draw bolt is equipped with gasket, gasket will be adjusted convenient for adjusting bolt
Section set is fixed on front support rod or back stay, is also convenient for draw bolt and is fixed on drag hook is drawn on towing plate, avoiding device
It loosens.
Specifically, tooth pitch of the tooth pitch of first rack gear less than the second rack gear.
Specifically, the tooth pitch of the preceding adjustment gear is less than the tooth pitch of rear adjustment gear, by adjusting headband before rotating
Adjustment gear rotation before dynamic, and towing plate is moved left and right to towing plate by the first rack-driving, head is adjusted after same rotation
Adjustment gear rotates after drive, and moves left and right towing plate to towing plate by the second rack-driving, but due to the first rack gear
It is smaller relative to the second rack gear and rear adjustment gear with the tooth pitch of preceding adjustment gear, rotate the preceding adjusting head and rear tune of same degree
Section header, the mobile distance of towing plate is different, and the moving distance of towing plate is smaller when adjusting head before rotating, when adjusting head after rotation
The moving distance of towing plate is larger.
Working principle: the edge of surgical bed is embedded into fixed plate, and the edge of operating bed is made to be in upper solid
Between stator and lower fixinig plate, upper fixinig plate and lower fixinig plate is driven to move up and down by rotation fixing bolt, it is fixed in change
The distance between piece and lower fixinig plate are allowed to clamp at the edge of operating bed, also can change fixed link piece and lower fixinig plate
Relative to the position inside fixed plate, to change the height of fixed plate, the height of device when in use is adjusted, then
Back stay and front support rod are rotated, the angle formed between it is adjusted, enables devices to the body contour for adapting to different patients, then
It is screwed by strut bolt and fixes junction, guarantee the stability of device, then moved on front support rod or back stay
Adjusting set, control seat are linked together by control-rod and adjusting set, to the position of control seat be adjusted, after regulating
The position of adjusting set is fixed by adjusting bolt, to say that the position of control seat is fixed, between front and back strut and control-rod
Control seat can more effectively be supported by forming triangle, avoid the position for controlling seat during operation mobile, traction is drawn
Hook is extend into the tissue near the affected part of patient, and by adjusting head after rotation, adjustment gear is rotated after drive, and passes through second
Rack-driving moves left and right towing plate faster to towing plate, by the tissue pulling of patient, after pulling open roughly, before rotation
Adjustment gear rotation before head drives is adjusted, and makes towing plate is slower to move left and right to towing plate by the first rack-driving, energy
It is enough that tissue is accurately pulled into suitable position, and can be according to circumstances adjusted at any time during operation.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
