Description
Technical field
This utility model relates to medical surgical instrument technical field.
Background technology
The abundant exposure of surgical field of view is one of key factor determining successful surgery.In some surgical procedures, the bodily tissues such as organ may stop that surgeon needs the region touched in operation.Surgical operation uses drag hook traditionally, adopts the drag hook of different shape as retractor, make operative site appear good according to difference operation.But along with the development of less invasive techniques, operative incision is more and more less, drag hook is obviously not suitable for the Minimally Invasive Surgery of such as chamber mirror or endoscopic procedure.
The endoscope-assistant surgery Minimally Invasive Surgery that to be namely surgeon guide operate surgical instruments to implement by the monitor image transferred out after inserting tiny light source, video camera from minimal incision *.Because Minimally Invasive Surgery otch is less, drag hook is inconvenient to enter otch, have or even cannot operative incision be entered, thus patient's (implement operation people) usually uses and has the metallic rod body of smooth heads to go deep into otch inside to be pushed aside by tissue, but organizing in body is all comparatively smooth, be difficult to be pushed aside.Therefore, patient can add one deck gauze between metallic rod body and tissue, to increase frictional force between the two, makes tissue be not easy landing.But in endoscope-assistant surgery, operative incision is too little, gauze cannot be sent easily to tractive position, and organize comparatively otch chin-deep when what need tractive, be difficult to especially realize sending of gauze, thus make surgical field of view unintelligible, cause operating time to extend, increase operation risk.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
A kind of Wicresoft tractive rod as shown in Fig. 1-5, comprise the body of rod 1 and dop 2, described dop 2 is connected with the body of rod 1 lower end by clamping mechanism; The described body of rod 1 upper end is round and smooth curved surface, is provided with plural through hole through vertically in the described body of rod 1, and described through hole upper end extends to outside the body of rod 1 and the oblique groove 7 exposed with the body of rod 1 upper section periphery is through; The steel wire 3 of more than two is fixed in described dop 2 upper surface, and described steel wire 3 is each passed through the through hole of the described body of rod 1 and upper end is stretched out outside the body of rod 1 along groove 7, the gauze clamping that the body of rod 1 upper end can be wound around; The described body of rod 1 epimere is also provided with gauze disconnecting prevention structure.
As a kind of preferred structure, all uniform arrangements of axle centered by the centrage of the body of rod 1 of described through hole and oblique groove 7.For the ease of making, described body of rod inner via hole is two, and the steel wire 3 on dop 2 is two.
Described clamping mechanism comprises two resilient inserting joints 4 of dop 2 upper surface and two draw-in grooves 6 of the body of rod 1 lower surface, two draw-in grooves 6 clamping of described two resilient inserting joints 4 and the body of rod 1 lower surface.Two resilient inserting joints 4 are identical with the inserting mode of netting twine crystal connector with the connected mode of the body of rod 1, and push in the draw-in groove 6 of body of rod lower end by the resilient inserting joint 4 of elastic chuck 2, can realize the connection of the two, same dismounting also facilitates.Described clamping mechanism also can establish steady pin in dop 2 upper end, establishes friction tight hole with it to fix dop 2, or adopt the cooperation of collision bead structure between the two in the body of rod 1 lower end.
As a kind of preferred structure, the described body of rod 1 epimere is provided with reverse taper, the top of described reverse taper is spherical crown shape, described reverse taper lower end is connected with the columniform body of rod 1, the oblique groove 7 through with through hole is located at described reverse taper part, and the structure of reverse taper also can avoid the gauze slippage of parcel on it.Simultaneously in order to increase the frictional force between the body of rod 1 and gauze, prevent gauze in operation process from coming off from the body of rod 1, gauze disconnecting prevention structure is also provided with at the body of rod 1 epimere, described gauze disconnecting prevention structure is the cross projection 5 that the outer surface of the body of rod (1) upper end distributes, and gauze disconnecting prevention structure also can be reticulate patterned surface or cone-shaped projection.So just make gauze in the body of rod 1 upper end fixation, the simultaneously existence of gauze increases the frictional force between tissue and tractive rod, make to facilitate and safety by draw tissue, to reach the abundant exposure of surgical field of view.
In order to adapt to the operation compared with deep tissues, be 6cm by the Design of length of the body of rod 1 epimere reverse taper, the length of the cylindrical body of rod 1 is 34cm, diameter is 5mm, described steel wire 3 diameter is 2mm, and described steel wire 3 length is 39cm.The diameter of the body of rod 1 is only 5mm, steel wire 3 diameter is 2mm, and its inner via hole can only be two, and the body of rod 1 diameter of 5mm can enter otch easily, and not with other operating theater instruments interfere, many tractives rods can also be put in time necessary to realize the tractive to larger tissue.
During concrete operations, bundle is rolled in the reverse taper outer surface on the body of rod 1, the cross protruding 5 on its outer surface is utilized to increase the frictional force of the body of rod 1 and gauze, prevent gauze slippage, in two through holes that two steel wires 3 fixing on dop 2 are interted in the body of rod 1, in the draw-in groove 6 resilient inserting joint 4 of dop 2 upper surface being pushed into the body of rod 1 lower surface, clamping is firm with it, 3, steel wire can along through hole, groove 7 stretches out outside the body of rod 1, under the steel wire 3 of two rigidity clamps, gauze is firmly fixed on the body of rod 1, stretch out smoothly at the port of export for the ease of steel wire 3, the upper end of steel wire 3 is outwards tilted slightly.
This utility model can not only be applied in routine operation, can also be applied in the operation of endoscope-assistant surgery or comparatively dark tissue, otch can be entered easily, and not with other operating theater instruments interfere, many tractive rods can also be put in realize the tractive to larger tissue time necessary, the simultaneously existence of gauze increases the frictional force between tissue and tractive rod, make to facilitate and safety by draw tissue, to reach the abundant exposure of surgical field of view.This utility model have structure simple, easy to operate, make gauze not easily slippage, the convenient tissue to otch depths or organ carry out Wicresoft's tractive rod of tractive, improve operation technique speed and safe coefficient, be particularly useful in Minimally Invasive Surgery operation.
