Abstract
A nerve surgery multifunctional retractor is substantially composed of a main plate (1), a movable drawing plate (2), a positioning plate (10), hook fixers (4), and a drawing hook (8). The utility model is characterized in that one end of the main plate (1) is vertically fixed with the positioning plate (10), the movable drawing plate (2) via a hollow chute (9) at lower end is mounted on the main plate (1), parallel with the positioning plate (10), the movable drawing plate (2) and the positioning plate (10) are both mounted with two hook fixers (4) via the hollow chute (9). The utility model can select different hooks according to the soft tissues in different thicknesses, to adjust the left and right distances, and upper and lower distances of the coupled hooks, to completely expose soft tissue, without hook drop.
Description
This utility model relates to medical apparatus and instruments, employed exposure retractor when specifically a kind of capable neurosurgery cranium brain or spinal operation.
When neurosurgery row cranium brain or spinal operation, usually need to retract skin and muscular tissue, method in the past is to adopt a kind of retractor that utilizes lever principle to make, comparatively require great effort when retracting, and drag hook is single a kind of, the soft tissue that can not be fit to different-thickness, drag hook is crossed dark or shallow excessively with respect to local soft tissue, influence operation technique, be expert in a big way spinal lesion when operation, be difficult to well expose, and fixing insecure when retracting, sometimes drag hook is easily thrown off automatically, and the influence operation is carried out.
The purpose of this utility model is to provide a kind of neurosurgery multi-functional retractor, and it can adjust the position and the spacing of drag hook easily according to operative site and size, selects drag hook according to the different-thickness of soft tissue, and drag hook is difficult for throwing off when retracting.
The technical solution of the utility model is: the multi-functional retractor of neurosurgery mainly is made up of mainboard, movable arm-tie, location-plate, retractor holder and drag hook, it is characterized in that: an end of mainboard is connected with perpendicular location-plate, movable arm-tie is installed on the mainboard by the hollow groove of its lower end, and parallel with location-plate, movable arm-tie and location-plate all are equipped with two retractor holders by hollow runner.
This utility model can be selected suitable drag hook according to the soft tissue of different-thickness, and by the between left and right distance of drag hook tuning knob adjustment to hook, the degree of tightness gim peg is adjusted to the distance between the upper and lower to drag hook, and soft tissue is fully exposed, and drag hook is difficult for throwing off.
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
This utility model is the metal manufacturing, the outside of mainboard (1) is the dentation of crouching, the one end is connected with perpendicular location-plate (10), movable arm-tie (2) is installed on the mainboard (1) by the hollow groove of its lower end, and parallel with location-plate (10), be equipped with movable tuning knob (11) between movable arm-tie (2) and the mainboard (1), adjust the position of movable arm-tie (2) on mainboard (1) by screwing movable tuning knob (11), thus the folding distance of adjustment activity arm-tie (2) and location-plate (10).All be equipped with the hollow runner (9) that moves up and down for retractor holder (4) on movable arm-tie (2) and the location-plate (10), two pairs of retractor holders (4) are fixed on movable arm-tie (2) and the location-plate (10) by gim peg (7) and hollow runner (9).The neck of hook of drag hook (8) is the dentation of crouching, and hook is middle recessed, the crotch of cup.Retractor holder (4) is provided with the hole of passing for the drag hook neck of hook, mainly reaches the internal gear that links to each other with drag hook tuning knob (6) by latch (5), drag hook tuning knob (6) and constitutes.Latch (5) places the outside of retractor holder (4), and the drag hook handle passes retractor holder (4), and drag hook tuning knob (6) can make drag hook (8) move left and right by its internal gear, and blocks drag hook (8) by latch (5).Loosening gim peg (7) can make drag hook (8) along with retractor holder (4) moves up and down along the hollow runner (9) in movable arm-tie (2) and the location-plate (10).Can select the drag hook (8) of different model according to the different-thickness of soft tissue.During use, at first according to soft tissue thickness, select suitable a pair of or two pairs of drag hooks (8), be installed on the retractor holder (4), according to otch length, degree of tightness gim peg (7) is adjusted the distance between the upper and lower of two pairs of drag hooks (8), also rotatable drag hook tuning knob (6), adjust paired drag hook distance between left and right, after adjusting the position, behind the soft tissue with drag hook (8) insertion incision, rotation activity tuning knob (11), drag hook separately, muscle is fully exposed, after retracting,, drag hook (8) is maintained the original state owing to the tension force of soft tissue forms frictional force between mainboard (1) and movable arm-tie (2), can not get loose automatically, after operation was finished, rotation activity tuning knob (11) can unclamp gim peg (7) and take off drag hook.
Claims (3)
