When the auxiliary epitheca pipe of peeling sheath inserts human body, can be very easily that peeling sheath is separated with epitheca pipe, can not make again epitheca pipe skid off human body, described peeling sheath 9 is provided with ，Qie gap, two gaps away from the sidewall that hinders one end of holder tip shape and extends to the end away from block piece one end.For convenient, also peeling sheath can be cut away half the one end away from block piece, as preferably, the large two halves such as cut open into best.When epitheca pipe inserts after human body, can directly peeling sheath be torn in two separated with epitheca pipe.
As another kind of mode, described peeling sheath 9 is provided with and is solidified as a whole with peeling sheath and for peeling sheath being separated into completely to the separation member 10 of two halves away from one end of tip shape.Described separation member is similarly two halves, and is solidified as a whole in peeling sheath, when no longer needing peeling sheath, only needs both hands to pull separation member just peeling sheath can be separated into two halves, departs from epitheca pipe completely.
As shown in Figure 7, in order to guarantee that epitheca Guan Buhui skids off easily in human body, the edge that described epitheca pipe is the end, one end of tip shape near holder is also provided with the outside turnup of relative epitheca pipe and forms curling and for stoping epitheca pipe from the block piece 11 of slippage in human body; Described block piece 11 is more than two, and is uniformly distributed in epitheca tube edge edge.
In order better to realize the present invention, described epitheca pipe is also provided with static line 12 away from one end of block piece, and static line extends to outside peeling sheath; One end that described static line is positioned at outside peeling sheath is also provided with the traction piece 13 of being convenient to user traction static line.Described traction piece can be little ball, also can be tablet, as long as can play convenient traction static line.When inserting epitheca pipe, in order to guarantee that epitheca pipe is positioned at peeling sheath completely, can pull traction piece that epitheca pipe is pulled back, make epitheca pipe front end be positioned at peeling sheath completely, to insert smoothly in human body; After operation completes, when epitheca pipe need to be extracted, also can hold traction piece equally, epitheca pipe is pulled out outside human body slowly.
According to above-described embodiment, just can realize well the present invention.What deserves to be explained is; under prerequisite based on said structure design, for solving same technical problem, even if some that make in the present invention are without substantial change or polishing; the essence of the technical scheme adopting is still the same with the present invention, therefore it also should be in protection scope of the present invention.
