Produce dislocation.
In order to make those skilled in the art be more fully understood that technical scheme, below will knot
The present invention is described in further detail to close the drawings and specific embodiments.
See Fig. 1-Fig. 6, in one embodiment of the invention, it is provided that a kind of titanium clamp pincers,
Including: jaw 1, rotary switch 3, firing handle 4, fixed handle 5, lower cover component 6.Should
Lower cover component 6 includes: jaw fixed plate 61, closure member 62, clamp push rod 63, lower cover 64.
Jaw 1 includes proximally-located claw beam 2, and also includes a pair be connected with claw beam 2 at far-end
Jaw member 11 that can be movable between spaced position and approximated position, and a pair jaw member
At least one in the outer surface 111 and 112 of 11 is nonplanar structure.Closure member 62
In the far-end of clamp push rod 63 and to be socketed in jaw 1 outside, and can be at the work applying push rod 63
Relative motion is produced along the axial of this applying push rod 63 and jaw member 11 with lower, so that one
To jaw member 11 close to separate.Closure member 62 and the outer surface 111 of jaw member 11
The inner surface 621 and 622 contacted with 112 has the outer surface 111 with jaw member 11
With the structure of 112 complete complementaries, thus the in-profile cross section of closure member 62 and two jaws
Exterior contour cross section when component 11 closes is the non-rectangular shape substantially coincideing, although now
There is certain fit-up gap, but due to nonplanar structure complete complementary, thus inhibit a pair
Along the length travel being perpendicular to claw beam 2 axial direction when jaw member 11 closes.In operation,
Owing to the outer surface of jaw member 11 is nonplanar structure, when jaw 1 initially opens, hold
Dynamic firing handle 4, then apply push rod 63 and promote closure member 62 to be moved by proximate, by
A pair jaw member 11 is gradually made to be squeezed power, under the effect of extruding force, a pair jaw member
11 gradually close.Owing to the inner surface of closure member 62 with the outer surface of jaw member 11 is
Complementary nonplanar structure, the nonplanar structure of this complementation makes the inner side table at closure member 62
Face produces with the contact position of the outer surface of jaw member 11 and is perpendicular to the vertical of claw beam 2 axial direction
To restraint, this restraint makes jaw member 11 be not likely to produce dislocation when Guan Bi, thus
Molding well when enabling titanium to be clipped in Guan Bi blood vessel, thus ensure the success rate of operation.
Preferably, in a pair jaw member 11, the outer surface of at least one is convex surface, then close
The respective inside surface that part 62 contacts with the convex surface of jaw member 11 is concave surface, and concave profile
Longitudinally the most from inside to outside being gradually reduced of cross section.Hold firing handle 4, Guan Bi
Part 62 is moved by proximate under the effect applying push rod 63, and jaw member 11 is in Guan Bi
Under the extruding of part 62, gradually drawn close to approximated position by spaced position, until of completely closed, by
In the sidepiece contact surface structurally complete complementary of closure member 62 with jaw member 11, and close
Part 62 is again one piece rigid structure, so working as inner side concave surface and the jaw member of closure member 62
Outer convex surface when fitting like a glove, the suppression of the longitudinal restraint produced between identical contact surface
Lower necessarily make a pair jaw member 11 be not likely to produce to be perpendicular to the length travel that claw beam 2 is axial, from
And ensure that jaw 1 is difficult to dislocation when closing, ensured the good molding that titanium presss from both sides.
It is further preferred that the outer surface 111 and 112 of a pair jaw member 11 is convex surface,
The inner surface 621 of the closure member 62 that then convex configuration with a pair jaw member 11 contacts and
622 are concave surface, and the longitudinal of concave profile cross section the most gradually subtracts
Little.When the outer surface 111 of two jaw member 11 is symmetrical and identical convex surface knot with 112
Best results during structure.Such as, the convex surface of the outer surface 111 and 112 of a pair jaw member 11
The shape of the cross section of structure can be taper or semicircle or half elliptic or half Fructus Jujubae shape or ladder recklessly
Shape or triangle or zigzag, etc..Fig. 7-Figure 10 shows the two of a pair jaw member 11
Individual outer surface 111 and 112 is respectively symmetrical taper, isosceles trapezoid, right-angled trapezium and circle
The embodiment of arc.
Additionally, the two of a pair jaw member 11 outer surfaces 111 and 112 protruded can also
It it is different structures.Such as, two outer surfaces 111 and 112 of two jaw member 11 are
Different convex configuration, as being respectively the different convex configuration of taper and semicircle etc..
Further, convex configuration along jaw member 11 outer surface extend length substantially
Equal to the distance of closure member 62 with jaw member 11 relative motion, thereby guarantee that jaw 1 with
The keeping strokes of two jaw member 11 during closure member 62 relative motion, it is not susceptible to
Length travel and dislocation when causing Guan Bi, and easy to assembly.
Further, convex configuration extends to claw beam along the outer surface of jaw member 11
The outer surface of 2, and convex surface along the axial length of jaw 1 more than closure member 62 and jaw member
The distance of 11 relative motioies.Convex surface is more than along the length of the outer surface extension of jaw member 11
Closure member 62 and the distance of jaw member 11 relative motion, it is possible to better ensure that jaw member
11 keep strokes when moving relative to closure member 62, are not susceptible to length travel and cause Guan Bi
Time dislocation, and easy to assembly.
According to still another embodiment of the invention, the outside table of at least one in a pair jaw member 11
Face is concave surface, then the respective inside surface that closure member 62 contacts with the concave surface of jaw member 11 is
Convex surface, and being longitudinally the most from inside to outside gradually increased of this convex profile cross section.Two
The effect when outer surface 111 of individual jaw member 11 is symmetrical and identical concave structure with 112
Most preferably.The shape of the cross section of the concave structure of a pair jaw member 11 can be taper or semicircle
Shape or half elliptic or half Fructus Jujubae shape recklessly or trapezoidal or triangle or zigzag, etc..
Concave surface extends to the outer surface of claw beam 2 along the outer surface of jaw member 11, and
Concave surface along the axial length of jaw 1 more than or substantially equivalent to closure member 62 and jaw member 11 phase
Distance to motion, thereby it is ensured that dynamic when jaw member 11 is moved relative to closure member 62
Make consistent, be not susceptible to length travel and cause misplacing during Guan Bi, and easy to assembly.
