Specific implementation mode
Core of the invention is to provide a kind of titanium clamp pincers, and the jaw of the titanium clamp pincers is not likely to produce dislocation when being closed.
It is below in conjunction with attached drawing and specifically real in order to make those skilled in the art more fully understand technical scheme of the present invention
Applying example, the present invention is described in further detail.
Referring to Fig. 1-Fig. 6, in one embodiment of the invention, a kind of titanium clamp pincers are provided, including：Jaw 1, rotation button
3, firing handle 4, fixed handle 5, lower cover component 6.The lower cover component 6 includes：Jaw fixed plate 61, closure member 62, clamp push away
Bar 63, lower cover 64.Jaw 1 includes the claw beam 2 positioned at proximal end, and also include distally a pair for being connect with claw beam 2 can every
Movable jaw member 11 between open position and approximated position, and in the outer surface 111 and 112 of a pair of of jaw member 11 extremely
Few one is nonplanar structure.Closure member 62 is located at the distal end of clamp push rod 63 and is socketed in outside jaw 1, and can be pushed away in application
Relative motion is generated along the axial direction of the application push rod 63 and jaw member 11 under the action of bar 63, to make a pair of of jaw member 11
It approaches and separates.The inner surface 621 and 622 that closure member 62 is contacted with the outer surface 111 and 112 of jaw member 11 have with
The structure of the outer surface 111 and 112 complete complementaries of jaw member 11, thus the in-profile cross section of closure member 62 with two
Exterior contour cross section when jaw member 11 is closed is the non-rectangular shape substantially coincideing, although there are certain assembly at this time
Gap, but due to nonplanar structure complete complementary, along axial perpendicular to claw beam 2 when to inhibit a pair of of jaw member 11 to be closed
The length travel in direction.During surgery, since the outer surface of jaw member 11 is nonplanar structure, when jaw 1 initially opens
When, firing handle 4 is held, then applies push rod 63 and closure member 62 is promoted to be moved by proximate, gradually make a pair of of jaw member
11 are squeezed power, and under the action of extruding force, a pair of of jaw member 11 is gradually closed.Due to closure member 62 inner surface with
The outer surface of jaw member 11 is the nonplanar structure of complementation, and the nonplanar structure of this complementation makes in closure member 62
Side surface and the contact position of the outer surface of jaw member 11 generate longitudinal restraint perpendicular to 2 axial direction of claw beam, this
Restraint make jaw member 11 be closed when be not likely to produce dislocation, to enable titanium be clipped in closure blood vessel when well at
Type, to ensure the success rate of operation.
Preferably, outer surface at least one in a pair of of jaw member 11 is convex surface, then closure member 62 and jaw member
The respective inside surface of 11 convex surface contact is concave surface, and longitudinal height of concave profile cross section is transversely gradual from inside to outside
Reduce.Firing handle 4 is held, closure member 62 is moved under the action of applying push rod 63 by proximate, and jaw member 11 exists
It under the extruding of closure member 62, is gradually drawn close from spaced position to approximated position, until being closed completely, due to closure member 62 and jaw
The side contact surface of component 11 complete complementary in structure, and closure member 62 is one piece rigid structure, so working as closure member
When 62 inside concave surface and the outer convex surface of jaw member fit like a glove, longitudinal restraint for being generated between coincideing contact surface
A pair of of jaw member 11 is necessarily set to be not likely to produce perpendicular to the axial length travel of claw beam 2 under inhibition, to ensure that jaw 1 is closed
Shi Buyi misplaces, and has ensured the good molding of titanium folder.
It is further preferred that the outer surface 111 and 112 of a pair of of jaw member 11 is convex surface, then with a pair of of jaw structure
The inner surface 621 and 622 of the closure member 62 of the convex configuration contact of part 11 is concave surface, and the longitudinal direction of concave profile cross section
Height is transversely gradually reduced from inside to outside.When the outer surface 111 and 112 of two jaw members 11 is symmetrical and identical convex
The best results when structure of face.For example, the shape of the cross section of a pair of of 11 outer surface 111 of jaw member and 112 convex configuration
Shape can be taper or semicircle or half elliptic or half jujube Hu shape or trapezoidal or triangle or zigzag, etc..Fig. 7-Figure 10
Show that two outer surfaces 111 and 112 of a pair of of jaw member 11 are respectively symmetrical taper, isosceles trapezoid, right-angled trapezium
With arc-shaped embodiment.
In addition, the outer surface 111 and 112 of two protrusions of a pair of of jaw member 11 can also be different structure.Example
Such as, two outer surfaces 111 and 112 of two jaw members 11 are different convex configurations, such as can be respectively taper and half
The different convex configuration of circle etc..
Further, convex configuration along jaw member 11 outer surface extend length be substantially equivalent to closure member 62 with
The distance of 11 relative motion of jaw member thereby guarantees that two jaw structures during jaw 1 and 62 relative motion of closure member
Part 11 is kept strokes, and is not susceptible to length travel and is caused to misplace when being closed, and is easy to assembly.
Further, convex configuration extends to the outer surface of claw beam 2 along the outer surface of jaw member 11, and
Convex surface is more than closure member 62 at a distance from 11 relative motion of jaw member along the axial length of jaw 1.Convex surface is along jaw member 11
Outer surface extend length be more than closure member 62 at a distance from 11 relative motion of jaw member, can better ensure that jaw
Component 11 is kept strokes when being moved relative to closure member 62, is not susceptible to length travel and is caused to misplace when being closed, and assembling side
Just.
According to still another embodiment of the invention, outer surface at least one in a pair of of jaw member 11 is concave surface, then closes
The respective inside surface that component 62 is contacted with the concave surface of jaw member 11 is convex surface, and the longitudinal direction of the convex profile cross section is highly
Transversely gradually increase from inside to outside.The outer surface 111 and 112 of two jaw members 11 is symmetrical and identical concave structure
When best results.The shape of the cross section of the concave structure of a pair of of jaw member 11 can be taper or semicircle or half elliptic
Or half jujube Hu shape 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 is axial along jaw 1
Length be more than or substantially equivalent to closure member 62 is at a distance from 11 relative motion of jaw member, thereby it is ensured that jaw member 11
Keep strokes when being moved relative to closure member 62, is not susceptible to length travel and causes to misplace when being closed, and is easy to assembly.
Proximal end herein is limited according to industry practice, that is, person close from doctor is proximal end when performing the operation, opposite one
End is distal end.
Titanium clamp pincers provided by the present invention are described in detail above.Specific example used herein is to the present invention
Principle and embodiment be expounded, but the explanation of above example is only intended to help understand the principle of the present invention and its
Core concept, not limiting the scope of the present invention.It should be pointed out that coming for those skilled in the art
It says, without departing from the principle of the present invention, can be with several improvements and modifications are made to the present invention, these improvement and modification
It also falls within the protection scope of the claims of the present invention.
