Description
Technical field
A kind of the present invention relates to technical field of medical instruments, more particularly to disposable blood pipe clamp.
Background technology
At present, in surgical procedure, it is found that when focus needs surgery excision, in order to ensure surgical procedure steady implementation, need
The corresponding blood vessel of temporary close is wanted, the instrument for being used for cutting out in prior art blood vessel has a lot, and for example haemostatic clamp temporarily clamps blood
Pipe, it is to avoid blood flows out；Blood vessel can also be ligatured by suturing knot tying techniques.But when clamping blood vessel by haemostatic clamp
Hand-held haemostatic clamp is needed, for of short duration operation can be to use, but some operating times are very long, and special messenger's long-time is hand-held only
Blood pincers are obviously improper, and for ligation, just in case occurring loose ends or off-line in surgical procedure, can cause internal haemorrhage, and hinder
Mouth healing is slower.There is a kind of hemostatic clamp in prior art, energy Quick-clamped blood vessel prevents blood vessel from bleeding, for example：Chinese patent
Authorization Notice No.：CN201519174U, in authorized announcement date on July 7th, 2010, discloses a kind of blood closed for human vas folder
Pipe clamp, however the clamp on this blood vessel clip can elastic deformation, the junction of two sections of clamps arranges an arcuate socket, works as needs
During clamping blood vessel, on the inside of arcuate socket, outside be all subject to larger moment of torsion and deform, two sections of clamps fit together clamping blood vessel,
After blood vessel clamping, as vascular wall has good elasticity, clamp can also be subject to opposition, in order to keep clamp enough
Amount of elastic deformation, it is very thin that arcuate socket both sides position is all designed, clamp bending, arc bore deformation, is subject to very big on the outside of arcuate socket
Bending stress, junction is easily damaged, ruptures, so as to cause blood vessel clip to come off, on the other hand due to arcuate socket both sides position
Very thin, the difficult quality stability contorting at arcuate socket, easily produces defective products in process of production.
The content of the invention
The present invention is easily broken off coming off not to overcome blood vessel clip stability of the prior art poor in use
Foot, there is provided a kind of stability is good, non-damageable disposable blood pipe clamp during use.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of disposable blood pipe clamp, including the first jig arm, the second jig arm, the inner and second jig arm of first jig arm
Inner elastic connection, the outer end of first jig arm are provided with grab, and the outer end of second jig arm is provided with the card coordinated with grab
Seat, first jig arm, the medial surface of the second jig arm are cambered surface, pass through between first jig arm and the inner of the second jig arm
Nonrigid connector connects, and described nonrigid connector is in annular, and nonrigid connector, the first jig arm, the second jig arm are integral type
Structure, the two sides of the nonrigid connector are respectively equipped with some deep-slotted chip breakers along annulus distribution.Using front, the first jig arm,
The outer end of the second jig arm separates under the elastic force effect of nonrigid connector naturally, overall V-shaped structure, when clamping blood vessel, first
The deformation of generation when the second jig arm of jig arm connects is shared by whole nonrigid connector, without the need for the open arc shape on nonrigid connector
Hole, it is only necessary to drive deep-slotted chip breaker and can just meet deformation demand, and as nonrigid connector itself has longer intrados, outer arc
Face, the bending stress being subject to are less, even if long-time clamping blood vessel, nonrigid connector will not also fail, damages, rupture, use
More stable, surgical procedure is safer；And after the completion of operation, it is only necessary to scissors through the circle in the middle of nonrigid connector
The i.e. detachable blood vessel clip of nonrigid connector is cut off in hole, and dismounting is convenient, laborsaving, but also will not produce chip.
Preferably, the deep-slotted chip breaker of the nonrigid connector both sides is dislocatedly distributed.Deep-slotted chip breaker is dislocatedly distributed, can be relatively uniform
The deformation quantity for sharing nonrigid connector, on the inside of nonrigid connector, outside stress distribution more concentrates.
Preferably, the depth of the deep-slotted chip breaker is less than the 1/2 of elastic connection body thickness.
Preferably, the inner of first jig arm is respectively provided on two sides with location hole, the openend of the location hole is provided with
With the gathering sill connected on the inside of the first jig arm, the inner of second jig arm is respectively provided on two sides with positioning tab, positioning tab
Tip inside is provided with the locating dowel coordinated with location hole, and the depth of the gathering sill is gradually reduced from outer end to positioning nose end；Institute
The width for stating gathering sill gradually increases from positioning nose end to outer end.When first jig arm, the outer end of the second jig arm connect, the inner also leads to
The locating dowel crossed on positioning tab coordinates spacing with the location hole in the first jig arm, so as to share nonrigid connector middle part
Reaction force；Gathering sill plays guide effect to locating dowel, it is ensured that locating dowel accurate, stable can be snapped in location hole.
Preferably, being provided with groove on the outside of second jig arm, curved wire, the arc-shaped steel in the groove, is provided with
The two ends of silk are fixedly connected with the two ends of groove, and the middle part of curved wire is arched upward outside protrusion groove, the curved wire
Bending two ends form U-shaped relief portion, and towards slot opening end, the curvature of the curved wire is big for the bottom of the U-shaped relief portion
In the curvature of groove floor.As the maximum grip power of the first jig arm, the second jig arm is fixed, and blood vessel has, when
When the first jig arm, the second jig arm clamping blood vessel, blood vessel is still being bled, and cannot then clamp the blood at this point for common blood vessel clip
Pipe, and in this structure, if blood vessel is still bled after clamping, now curved wire is pressed in groove, the arc side of curved wire
Contact to varus and with the bottom surface of groove, as the curvature of curved wire is more than the curvature of groove floor, therefore in curved wire
Pressure effect under, the second jig arm can produce a diastrophic trend, so as to further increase blessing power, so as to clamp blood
Pipe.
Preferably, the bottom portion of groove gradually subtracts to centre to the thickness of the second jig arm medial surface from the two ends of groove
It is little.The thickness of groove middle part is little, big compared with two ends by the lower middle part deformation tendency of pressure effect of curved wire, so as to
Blood vessel can be clamped.
Preferably, be respectively equipped with some latches on first jig arm, the medial surface of the second jig arm, the latch cuts
Face semicircular in shape, the latch in second jig arm is highly less than the latch height in the first jig arm.
Preferably, being provided with the first card ear on the outside of the outer end of first jig arm, the outer end both sides of second jig arm set
There is the second card ear.Hemostatic clamp is clamped on blood vessel by frock, and the first card ear, the second card ear are easy to frock clamping blood vessel clip.
Therefore, the present invention has the advantages that：（1）Clamp blood vessel rear stability good, be hardly damaged during use,
Using safer；（2）Clamp pressure can be adjusted for different entries, keep blood vessel constriction stable.
