The present invention is released, and is not considered as limiting the invention.
As shown in Figure 1, centreless puncture outfit 100 includes seal assembly 3, casing 2, shaft and puncture tip 1.Centreless puncture outfit
100 front includes casing 2, puncture tip 1 and shaft.
Casing 2 is hollow pipe, with first end 21 and second end.The second end of casing 2 is selected by seal assembly 3
Property sealing, first end 21 selectively unlocks or is closed by puncture tip 1.The structure and seal assembly 3 and casing of seal assembly 3
2 connection type has been documented in the patent application document submitted before the applicant, including CN201710216813.8,
CN201710216814.2, CN201710299930.5, this will not be repeated here.
As shown in figure 4, puncture tip 1 includes first end, second end, middle part and sword.First end is tip, second end
Shape is identical as the shape of first end 21 of casing 2, and the present embodiment is preferably circular.It is intermediate between first end and second end
The outer surface in portion, middle part is smooth convex outward, also, sword is provided on the outer surface of middle part.Preferably, puncture tip
The end face of the second end at end 1 and the central axis of puncture tip 1 are perpendicular.
Puncture tip 1 is pivotally attached with casing 2.
Specifically, as shown in figure 3, casing 2 includes first rotating shaft bracket 212 and two accommodation grooves 211, first rotating shaft bracket
212 and two accommodation grooves 211 be all set on the end face of first end 21 of casing 2.First rotating shaft bracket 212 is located at two accommodatings
Between slot 211, first rotating shaft bracket 212, which has, to be passed through for shaft (not shown) and accommodates the through-hole of shaft.Preferably, first end
21 end face and the central axis of casing 2 are perpendicular.
As shown in figure 4, puncture tip 1 includes two the second rotary shaft racks 11, two the second rotary shaft racks 11 all have logical
Hole 111, through-hole 111 pass through for shaft (not shown) and accommodate shaft.Two linear distributions of the second rotary shaft rack 11, i.e., two
The central axis of a second rotary shaft rack 11 is conllinear, and two through-holes 111 are also on same straight line.Puncture tip 1 further include to
A few positioning column 12, preferably three.Two the second rotary shaft racks 11 and three positioning columns 12 are arranged at puncture tip 1
On the end face of second end.Correspondingly, casing 2 includes locating slot (not shown) identical with the quantity of positioning column 12, and locating slot is set
It is placed on the end face of first end 21, locating slot is to accommodate positioning column 12.Preferably, three positioning columns 12 are in puncture tip 1
It is uniformly distributed on the end face of second end, three locating slots are uniformly distributed on the end face of the first end 21 of casing 2.12 quilt of positioning column
Be placed in locating slot so that puncture tip 1 is conllinear with the central axis of casing 2, to realize positioning function, due to positioning column 12 with
There is frictional force between locating slot, can to realize between puncture tip 1 and casing 2 and tentatively fix, prevent 1 phase of puncture tip
Undesirable pivot is generated for casing 2.The meaning tentatively fixed: the frictional force between positioning column 12 and locating slot is little, energy
The gravity that puncture tip 1 is subject in itself is offset, so that puncture tip 1 will not generate pivot under gravity；It is inserted in instrument
Fashionable, the external force that instrument applies puncture tip 1 is greater than the frictional force between positioning column 12 and locating slot, and puncture tip 1 produces
It is raw to pivot, so that instrument is pierced by from casing 2 and enters the body cavity of patient.Puncture tip 1 pivots and state such as Fig. 2 after opening
It is shown, instrument is not shown in the figure.
Accommodation groove 211 is to accommodate the second rotary shaft rack 11.When each second rotary shaft rack 11 is placed in corresponding appearance
After setting slot 211, the through-hole 111 of two the second rotary shaft racks 11 is conllinear with the through-hole of first rotating shaft bracket 212.Due to accommodation groove
211 width is greater than the width of the second rotary shaft rack 11, and due to two linear distributions of the second rotary shaft rack 11, two
Accommodation groove 211 is arc-shaped distribution, therefore has space that shaft is allowed to penetrate, and specifically, shaft is worn from one end of a through-hole 111
Enter, be pierced by after the through-hole of first rotating shaft bracket 212 from one end of another through-hole 111, then the both ends of shaft are expanding, makes
The diameter for obtaining the both ends of shaft is greater than the diameter of through-hole 111, by shaft indwelling in two through-holes 111 and first rotating shaft bracket 212
Through-hole among.The internal diameter of three through-holes is equal.
Stress surface is provided on the inner wall of the middle part of puncture tip 1.When instrument is inserted into, the top of instrument passes through stress surface
It exerts a force to puncture tip 1, so that puncture tip 1 overcomes the frictional force between positioning column 12 and locating slot and produces by axis of shaft
Raw to pivot, so that the first end 21 of casing 2 is opened, instrument be can be inserted into the body cavity of patient.Stress surface can be plane or
Curved surface.
Puncturing hole with the extraction of centreless puncture outfit 100, on the outer surface and patient body of the middle part of puncture tip 1
Hole wall be in contact, it is generated make every effort to promote so that puncture tip 1 is generated pivot, can so that puncture tip 1 and casing 2 are conllinear
Casing 2, puncture tip 1 are successively extracted out of patient's body lumen, realize the separation of centreless puncture outfit 100 and patient body.
Due to using shaft to connect between puncture tip 1 and casing 2, the connection knot in pivoting process including shaft
The resistance that structure needs to overcome is smaller, thus the pivot of puncture tip is more flexible.
The invention also includes the assemble methods of the front of centreless puncture outfit 100, comprising the following steps: S1. is by first rotating shaft
Bracket 212 is placed between two the second rotary shaft racks 11；S2. by shaft from the one of the through-hole 111 of second rotary shaft rack 11
End penetrates, one end of through-hole 111 after the through-hole of first rotating shaft bracket 212 from another the second rotary shaft rack 11 is pierced by,
The both ends of shaft are expanding, so that the diameter at the both ends of shaft is greater than the diameter of through-hole, by shaft indwelling in two the second shafts
Among the through-hole of bracket 11 and the through-hole of first rotating shaft bracket 212；S3. puncture tip 1 is pivoted towards casing 2, so that positioning
Column 12 is placed in locating slot so that puncture tip 1 is conllinear with the central axis of casing 2, and make puncture tip 1 with
It is realized between casing preliminary fixed.
