Abstract
The utility model relates to a porous elastic vessel clip, which comprises a pincer-like clip. The porous elastic vessel clip is characterized in that the pincer-like clip consists of a clamp mouth (1) and two clamp handles (2); wherein the clamp mouth (1) consists of an upper clamp bar (1-1) and a lower clamp bar (1-2); the inner sides of the upper clamp bar (1-1) and the lower clamp bar (1-2) are respectively provided with at least two opposite semicircular holes (1-3); and a spring (2-1) is arranged between the two clamp handles (2). Under the elasticity of the spring, the utility model can ensure that the closing force of the clamp mouth is always larger than the elasticity of the artery wall. In addition, the utility model is removed during operation through opening the clamp mouth by exerting pressure on the clamp handles of the vessel clip with the clip applier, thereby realizing the firm closure and easily eliminating the requirements for clinical operation. Moreover, the utility model can narrow the vessel within circular holes with different diameters, so as to narrow the vessel to different degrees.
Description
Technical field
This utility model relates to a kind of porous elastic force vascular clamp, is applicable in large animal operation constriction blood vessel and the vascular clamp that is implanted at its body, belongs to the medium-term and long-term intravital experiment apparatus of the animal technical field of implanting of large animal experiment.
Background technology
Vascular clamp is the apparatus of using always in surgical operation or experiment, in order to clamp the blood vessel blocking blood flow.For example, utilize vascular clamp to make the renal vascular hypertension model at surgical operation constriction renal artery; Make Atherosclerosis Model etc. at surgical operation constriction aorta or common carotid artery.In order to adapt to the needs of different blocking-up vascular flows, the existing vascular clamp that uses is varied, mainly is U type or V-type in shape, mainly is divided into metal and non-metallic material on the material.But the problem that vascular clamp faces mainly contains: one, the vascular clamp elastic force made of the metal material that hardness is big is big, folder power is strong, but long-time clamping, metal can damage by the folder blood vessel, secondly is that volume is heavy, and blood vessel is involved greatly, and easy landing forms foreign body in vivo; Two, the vascular clamp volume made of metal material that hardness is little or medical plastics nonmetallic materials is little, in light weight, but elastic force is little, and chucking power is poor.
In the prior art, when making large animal renal vascular hypertension model, after the renal artery constriction, blood pressure can raise gradually, the elastic force of arterial wall also can increase thereupon, if just non-elastic force vascular clamp loses the effect of constriction blood vessel and causes blood pressure drops this moment, modelling is unsuccessful.For example, using U type silver brain clip to make the renal vascular hypertension rat model in the animal experimental model at present.U type silver brain clip can be realized the making of kidney of rats vascular hypertension model in the toy experiment.But the hardness of silver is too little, and large animals such as dog, pig are because the bore of blood vessel is bigger, the elastic force of blood vessel is also bigger, the elastic force of making U type silver brain clip is not enough, and the variation of the external caliber of large animals such as rabbit, dog, pig is also bigger, U type silver brain clip but has only 1 bore, causes U type silver brain clip to use in the experiment of large animals such as dog, pig.At present, the constriction blood vessel is often realized with the method for artificial oversleeve of interim making or coil in the large animal experiment both at home and abroad, but because the bore of artificial oversleeve or coil is difficult to accurately, the bore of large animal blood vessel often has variation again simultaneously, causes the inaccurate of experimental result.In order to solve a difficult problem that faces in the experiment, need the special vascular clamp of exploitation.
The utility model content
The purpose of this utility model is in order to overcome the existing shortcoming that the vascular clamp bore is single, vascular clamp elastic force is little, a kind of porous elastic force vascular clamp to be provided.
The purpose of this utility model is achieved through the following technical solutions:

The purpose of this utility model can also be achieved through the following technical solutions:
A kind of embodiment of realizing this utility model purpose is: described semicircle orifice is equidistantly arranged, adjacent semicircle orifice big or small identical or inequality.At interval certain distance between the semicircle orifice, when making jaw closed jaw be that face contacts by pressing from both sides between the blood vessel, effectively avoided in the jaw closing course shear action to vascular tissue.
A kind of embodiment of realizing this utility model purpose is: the inboard of going up claw beam and following claw beam is respectively equipped with the semicircle orifice of three corresponding different bores, promptly constitutes the circular hole of three different bores after the jaw closure.
A kind of embodiment of realizing this utility model purpose is: the diameter of the semicircle orifice of three different bores is respectively 1.6mm, 1.3mm, 1.0mm, from jaw, arrange from large to small, can guarantee to make things convenient for experimental implementation simultaneously more than the dog renal artery constriction to 70%.If vascular clamp is used for constriction ventral aorta, carotid artery or other blood vessel, then the design in aperture can correspondingly change.
A kind of embodiment of realizing this utility model purpose is: two near-ends that clamp between the handle are connected with the resiliency supported sheet, and far-end is connected with spring.
A kind of embodiment of realizing this utility model purpose is: the outside of going up claw beam and following claw beam is respectively equipped with the semicircle corresponding with its inboard semicircle orifice.
A kind of embodiment of realizing this utility model purpose is: this utility model is made of purity height, stainless steel substrates and stainless steel wire that hardness is big.
A kind of embodiment of realizing this utility model purpose is: go up claw beam and can be provided with anti-skidding stricture of vagina with the inboard semicircle orifice of following claw beam place.
A kind of embodiment of realizing this utility model purpose is: go up claw beam and can be provided with air bag or elasticity medical material with the inboard semicircle orifice of following claw beam place, as medical grade rubber bar or medical silica-gel bar, to reduce the shearing force of jaw to blood vessel.
The beneficial effect that the utlity model has is as follows:
1, this utility model is because the elastic force effect of spring, and the closing force that can guarantee jaw is all the time greater than the elastic force of arterial wall.In addition, in operation when needing to remove the vascular clamp of this utility model, only need to exert pressure for the pincers handle of vascular clamp to unclamp jaw get final product, realized closed firmly, remove clinical operation requirement easily with Clip Applier.And, utilize this utility model with Vasoconstriction in the circular hole of different bores, to reach with the purpose of Vasoconstriction to different stenosis.
2, the utlity model has spring structure, can guarantee that jaw has big elastic force and strong folder power.
3, this utility model is simple for structure, easy to operate.
