Detailed description of the invention
Core of the present utility model is to provide a kind of titanium clamp pincers, and the jaw of this titanium clamp pincers not easily produces dislocation when closed.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1-Fig. 6, in an embodiment of the present utility model, provide a kind of titanium clamp pincers, comprising: jaw 1, rotary switch 3, firing handle 4, fixed handle 5, lower cover component 6.This lower cover component 6 comprises: jaw fixing head 61, closure member 62, clamp push rod 63, lower cover 64.Jaw 1 comprises the claw beam 2 being positioned at near-end, and also far-end comprise be connected with claw beam 2 a pair can be movable between spaced position and approximated position jaw member 11, and at least one in the outer surface 111 and 112 of a pair jaw member 11 is nonplanar structure.Closure member 62 is positioned at the far-end of clamp push rod 63 and to be socketed in jaw 1 outside, and under the effect applying push rod 63, can produce relative motion along the axis of this applying push rod 63 and jaw member 11, thus make a pair jaw member 11 close with separate.The inner surface 621 and 622 that closure member 62 and the outer surface 111 of jaw member 11 contact with 112 has the structure with outer surface 111 and 112 complete complementary of jaw member 11, exterior contour cross section when the in-profile cross section of closure member 62 and two jaw member 11 close thus is the non-rectangular shape of substantially coincideing, although now there is certain fit-up gap, but due to nonplanar structure complete complementary, thus along the length travel perpendicular to claw beam 2 axial direction when inhibit a pair jaw member 11 to close.In operation, outer surface due to jaw member 11 is nonplanar structure, when jaw 1 initially opens, hold firing handle 4, then applying push rod 63 impels closure member 62 distally to be moved by near-end, make a pair jaw member 11 be squeezed power gradually, under the effect of extruding force, a pair jaw member 11 closes gradually.Due to the nonplanar structure that the inner surface of closure member 62 and the outer surface of jaw member 11 are complementary, the nonplanar structure of this complementation makes the longitudinal restraint produced in the contact position of the inner surface of closure member 62 and the outer surface of jaw member 11 perpendicular to claw beam 2 axial direction, this restraint makes jaw member 11 not easily produce dislocation when closed, thus molding well when enabling titanium be clipped in closed 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 the respective inside surface that closure member 62 contacts with the convex surface of jaw member 11 is concave surface, and the longitudinal of concave profile cross section highly transversely from inside to outside reduces gradually.Hold firing handle 4, closure member 62 is distally moved by near-end under the effect applying push rod 63, jaw member 11 is under the extruding of closure member 62, drawn close to approximated position by spaced position gradually, until completely closed, due to closure member 62 and the sidepiece contact surface structurally complete complementary of jaw member 11, and closure member 62 is one piece rigid structures, so when the inner side concave surface of closure member 62 and the outer convex surface of jaw member fit like a glove, a pair jaw member 11 must be made under the suppression of the longitudinal restraint produced between identical contact surface not easily to produce length travel perpendicular to claw beam 2 axis, thus not easily misplace when ensureing that jaw 1 closes, ensure the good molding that titanium presss from both sides.
Further preferably, the outer surface 111 and 112 of a pair jaw member 11 is convex surface, the inner surface 621 and 622 of the closure member 62 then contacted with the convex configuration of a pair jaw member 11 is concave surface, and the longitudinal of concave profile cross section highly transversely from inside to outside reduces gradually.The best results when the outer surface 111 and 112 of two jaw member 11 is symmetrical and identical convex configuration.Such as, the shape of the cross section of the convex configuration of the outer surface 111 and 112 of a pair jaw member 11 can be taper or semicircle or half elliptic or half Fructus Jujubae shape or trapezoidal or triangle or zigzag recklessly, etc.Two outer surfaces 111 and 112 that Fig. 7-Figure 10 shows a pair jaw member 11 are respectively the embodiment of symmetrical taper, isosceles trapezoid, right-angled trapezium and circular arc.
In addition, two outer surfaces 111 and 112 protruded of a pair jaw member 11 also can be 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 equals the distance of closure member 62 and jaw member 11 relative motion substantially along the length that the outer surface of jaw member 11 extends, ensure keeping strokes of in jaw 1 process with closure member 62 relative motion two jaw member 11 thus, dislocation when not easily length travel occurring and cause closed, and easy to assembly.
Again further, convex configuration extends to the outer surface of claw beam 2 along the outer surface of jaw member 11, and convex surface is greater than the distance of closure member 62 and jaw member 11 relative motion along the length of jaw 1 axis.Convex surface is greater than the distance of closure member 62 and jaw member 11 relative motion along the length that the outer surface of jaw member 11 extends, keep strokes when can ensure that jaw member 11 is moved relative to closure member 62 better, dislocation when not easily length travel occurring and cause closed, and easy to assembly.
According to another embodiment of the present utility model, in a pair jaw member 11, the outer surface of at least one is concave surface, the respective inside surface that then closure member 62 contacts with the concave surface of jaw member 11 is convex surface, and the longitudinal of this convex profile cross section highly transversely from inside to outside increases gradually.The best results when outer surface 111 and 112 of two jaw member 11 is symmetrical and identical concave structure.The shape of the cross section of the concave structure of a pair jaw member 11 can be taper or semicircle or half elliptic or half Fructus Jujubae shape or trapezoidal or triangle or zigzag recklessly, etc.
Concave surface extends to the outer surface of claw beam 2 along the outer surface of jaw member 11, and concave surface is greater than along the length of jaw 1 axis or substantially equals the distance of closure member 62 and jaw member 11 relative motion, thus, keep strokes when ensure that jaw member 11 is moved relative to closure member 62, dislocation when not easily length travel occurring and cause closed, and easy to assembly.
Near-end herein, far-end limited according to industry practice, and be namely near-end from person close to doctor during operation, opposite end is far-end.
Above titanium clamp pincers provided by the utility model is described in detail.Apply concrete example herein to set forth principle of the present utility model and embodiment, but the explanation of above embodiment just understands principle of the present utility model and core concept thereof for helping, the restriction not to this utility model protection domain.Should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model principle, can also carry out some improvement and modification to this utility model, these improve and modify and also fall in the protection domain of this utility model claim.
