Abstract
The utility model provides an endoscopic two-way knot pusher. The endoscopic two-way knot pusher comprises a handle, a push rod and a head end, all of which are orderly connected together; the head end comprises two end rods which are connected to the push rod in Y shape; an included angle of 150-170 degrees is formed between a plane formed by the two end rods and the push rod; major-arc-shaped circular grooves are formed in one ends, far away from the push rod, of the two end rods, respectively; and the two major-arc-shaped circular grooves are opposite in open direction. The endoscopic two-way knot pusher is convenient to use and easier to control in force and accuracy; a surgeon can tie the knot independently with one hand holding the two ends of a suture and the other hand pushing the knot; the effect of two-way knot pushing is achieved and the two ends of the suture knob are equal in stress; the knot can be tied in situ without pulling the ligated blood vessel and the suture knot, and therefore, the risk that the blood vessel and the suture knot are avulsed is obviously reduced.
Description
Technical field
This utility model belongs to medical instruments field, relates in particular to two-way knot pusher under the mirror of a kind of chamber.
Background technology
Along with the development of chamber mirror technology, increasing operation can complete under the mirror of chamber, and operation wound obviously reduces, and patient's post-operative recovery is faster.But in endoscope-assistant surgery, surgeon can not with the hands be tied a knot as traditional operation, must rely on apparatus and complete.The efficiency of knotting and quality directly affect the incidence rate of the complication such as operating time length and angiorrbagia.Surgeon is expensive time in knotting process under the mirror of chamber often, and easily occur that toe-in is not tight, the situations such as ligature slippage.
Although have in the market knot pusher under the mirror of chamber, have obvious weak point: the first, between knot pusher and suture, frictional force is large, not only affects the judgement of surgical doctor to toe-in tension force, and the suture that easily weares and teares, and causes suture fracture; The second, in knotting process, suture is slippage from knot pusher groove easily, delays operating time; The 3rd, maximum problem is that current knot pusher is unidirectional knot, knotting process need operating doctor is caught one end of line with hands, assist to strain the suture other end by assistant, then tied with an other hand push by operating doctor, two people are good fit for knot process need, otherwise easily cause both sides suture unbalance stress, cause toe-in to be pulled and cause slippage or tie a knot not tight.If in the time of ligation small artery, toe-in slippage easily causes compared with massive hemorrhage, or pulls toe-in and cause vascular tear.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, and be not used in restriction this utility model.
As illustrated in fig. 1 and 2, wherein, Fig. 1 is the Facad structure schematic diagram of two-way knot pusher one embodiment under the mirror of this utility model chamber, and Fig. 2 is the side structure schematic diagram of two-way knot pusher under Fig. 1 lumen mirror.
Two-way knot pusher under the mirror of a kind of chamber, comprise handle 1, push rod 2 and head end 3, described head end 3 comprises end bar 31 and end bar 32, one end of described end bar 31, end bar 32 is respectively equipped with major arc circular groove 33 and major arc circular groove 34, described end bar 31,32 other ends are connected on push rod 2, and described push rod 2 is connected on handle 1 away from end bar 31 and end bar 32 direction one end;
Between the plane that described end bar 31 and end bar 32 form and push rod 2, form the angle of 150～170 °, between described end bar 31 and end bar 32, shape has angle; Major arc circular groove 33 on described end bar 31 and end bar 32 and the opening direction of major arc circular groove 34 are contrary.
More specifically, in this utility model embodiment, between end bar 31 and end bar 32, form 30～120 ° of angles, between the plane that end bar 31 and end bar 32 form and push rod 2, form the angle of 160 °.
