Description
Technical field
This utility model relates to technical field of medical instruments, particularly relate to a kind of in operation process the ligation clip for ligation blood vessel.
Background technology
At present, in operation process, when finding that focus needs excision, in order to ensure operation process steady implementation, need the corresponding blood vessel of temporary close, the instrument for cutting out blood vessel in prior art has a lot, such as mosquito forceps temporarily clamps blood vessel, avoids blood to flow out; Also ligation can be carried out by sewing up knot tying techniques to blood vessel.But need hand-held mosquito forceps when clamping blood vessel by mosquito forceps, to use for of short duration operation, but some operating time is very long, the long-time hand-held mosquito forceps of special messenger is obviously improper, and for ligation, just in case there is loose ends or off-line in operation process, internal hemorrhage can be caused, and wound healing is slower.A kind of hemostatic clamp is also had in prior art, energy Quick-clamped blood vessel, prevent blood vessel from bleeding, such as: Chinese patent Authorization Notice No.: CN201519174U, authorized announcement date on July 7th, 2010, disclose and a kind ofly press from both sides the vascular clamp closed for human vas, but clamp on this vascular clamp can elastic deformation, the junction of two sections of clamps arranges an arcuate socket, when needs clamping blood vessel, inside arcuate socket, outside is all subject to larger moment of torsion and is out of shape, two sections of clamps fit together clamping blood vessel, after blood vessel clamping, because blood vessel wall has good elasticity, clamp also can be subject to opposition, in order to the amount of elastic deformation keeping clamp enough, it is very thin that position, arcuate socket both sides is all designed, clamp bends, arcuate socket is out of shape, very large bending stress is subject to outside arcuate socket, junction is easily damaged, fracture, thus cause vascular clamp to come off, on the other hand because position, arcuate socket both sides is very thin, the difficult quality stability contorting at arcuate socket place in process of production, easy generation defective products.
Utility model content
This utility model, in order to solve the aforementioned problems in the prior, provides a kind of stability good, non-damageable disposable ligation clip in use procedure.
To achieve these goals, this utility model adopts following technical scheme:
A kind of disposable ligation clip, comprise the first jig arm, second jig arm, the inner of described first jig arm is connected with the inner elasticity of the second jig arm, the outer end of described first jig arm is provided with grab, the outer end of described second jig arm is provided with the deck coordinated with grab, described first jig arm is connected by nonrigid connector with between the inner of the second jig arm, the first card ear is provided with outside the outer end of described first jig arm, the both sides, outer end of described second jig arm are provided with the second card ear, described nonrigid connector is annular, the two sides of described nonrigid connector are respectively equipped with the some arcuate grooves along annulus distribution, the first described jig arm, second jig arm, nonrigid connector is integral type structure.
Before using, first jig arm, the outer end of the second jig arm naturally separates under the elastic force effect of nonrigid connector, overall V-shaped structure, during clamp blood vessels, the deformation quantity produced when first jig arm second jig arm connects has been shared by whole nonrigid connector, without the need to opening arcuate socket on nonrigid connector, only need out arcuate groove just can meet deformation demand, and there is longer intrados due to nonrigid connector self, extrados, the bending stress be subject to is less, even if clamp blood vessel for a long time, nonrigid connector also can not lose efficacy, damage, fracture, use more stable, operation process is safer, and after operation completes, only need to cut off nonrigid connector with shears through in the circular hole in the middle of nonrigid connector, the first jig arm, the second jig arm drop naturally, dismantle convenient, laborsaving, can not produce unnecessary chip.
As preferably, the arcuate groove of described nonrigid connector both sides is dislocatedly distributed.Arcuate groove is dislocatedly distributed, can the relatively uniform deformation quantity sharing nonrigid connector, and inside nonrigid connector, outside stress distribution is more concentrated.
As preferably, the inner both sides of described first jig arm are respectively equipped with locating hole, the opening of described locating hole is provided with and the gathering sill be communicated with inside the first jig arm, the inner both sides of described second jig arm are respectively equipped with positioning tab, the tip inside of positioning tab is provided with the locating dowel coordinated with locating hole, and the degree of depth of described gathering sill reduces gradually from outer end to location nose end; The width of described gathering sill increases from location nose end gradually to outer end.When the outer end of the first jig arm, the second jig arm connects, the inner also coordinates spacing by the locating dowel on positioning tab with the locating hole in the first jig arm, thus shares the counteracting force of nonrigid connector middle part; Gathering sill plays guide effect to locating dowel, guarantees that locating dowel can accurate, stable snapping in locating hole.
As preferably, the medial surface of described first jig arm, the second jig arm is cambered surface, and the medial surface of described first jig arm, the second jig arm is respectively equipped with some latches.First jig arm, the second jig arm cambered surface laminating time have a squeezing action, blessing power more strengthens, and the first jig arm, second jig arm self-strength increase, not yielding in clamping process; Latch can further clamp blood vessels.
Therefore, it is good that this utility model has clamp blood vessels rear stability, not fragile in use procedure, uses safety benefits more.
