Abstract
The utility model belongs to the field of medical apparatus, which relates to an injury-free elastic blood vessel clamp. The blood vessel clamp is provided with two clamp arms, one end of each clamp arm is fixed together with a clamp handle and the other end of each clamp arm is a clamping end, the clamping ends are provided with penetration rivet holes which are used for thread fixation or riveted joint fixation and the clamp arms are made of an elastic medical material. The blood vessel clamp adopts an elastic medical material, the direct damage to the clamp arms is avoided, the overall weight is light, the traction influence on a blood vessel is small, a hollow clamp arm forms a structure similar to an air chamber and the pressure is balanced. One end of the blood vessel clamp is completely fixed and the other end of the blood vessel clamp can be fixed by medical threads, rivets or penetration rivets, the easy slip abuse of the existing blood vessel clamps is completely avoided and the adjustment of the blood vessel pressure can be achieved through the control to the knot strength of the fixing threads and the size of a knot ring. Therefore, the utility model has the characteristics of simple structure, science, reasonableness and convenient operation and the utility model can be used for the blood flow breaking of a clinical operation and an animal experiment.
Description
Technical field
This utility model belongs to medical instruments field, is used for the noinvasive elastic vessel folder of bloodstream blocking when relating to a kind of the operation.
Background technology
Vascular clamp appear as clinical operation and very big facility has been created in zoopery, rely on vascular clamp, a lot of operations as micro-vascular anastomosis, organ transplantation, the flap that coincide etc. all is able to security implementation.But, no matter be clinical practice or experimentation, all there is certain weak point in present vascular clamp: 1. general vascular clamp is as a kind of metallic weapon, the blood vessel contact clip of its metal material is in the face of being had damage undoubtedly by the folder blood vessel, practice also confirms, uses vascular clamp will cause very big damage to tunica intima for a long time, after blood flow is logical again, often, make operative failure because the damage of inner membrance causes local thrombus to form.2. the vascular clamp quality of metal is heavier, can't fix, and vascularization involves to whole piece.3. the existing general volume of vascular clamp is bigger, puts to be difficult for, and this causes certain difficulty to operation technique.4. existing vascular clamp is the plane with the contact surface of blood vessel, because the one end fixes, it very easily taking place to slide when operation and taking off mistake pressure of blood vessel and unbalanced, thereby makes surgical object increases of losing blood, and influences the quality of performing the operation.5. present microsurgery vascular clamp adopts simple fixation pressure mode, being difficult to implement blocking-up at the blood vessel of different sizes with the vascular clamp of same dynamics performs the operation, particularly thicker slightly tremulous pulse is difficult to reach the blocking blood flow purpose with existing vascular clamp, thin slightly blood vessel is then damaged too heavy, it is suitable to be difficult to accomplish.
To sum up, press at present and a kind ofly can be used for clinical operation and zooperal noninvasive, adjustable in pressure is whole, that weight is lighter, isostasy, not eely vascular clamp.
Summary of the invention
The purpose of this utility model is at existing blood vessel blocking technology above shortcomings, provide a kind of easy to use, haemostatic effect is certain, noninvasive, isostasy, adjustable, that weight is lighter, not eely vascular clamp.
The purpose of this utility model is achieved in that a kind of noinvasive elastic vessel folder, and it has two jig arm, and two jig arm one ends and clamp holder are fixed together, the other end of two jig arm is the clamping end, wear rivet hole on the clamping end, be used for that threading is fixed or riveted and fixed, jig arm adopts the elasticity medical material.Further, jig arm can be hollow structure, adopts medical grade rubber bar or medical silica-gel bar.During use, place blood vessel between two jig arm after, fixing the tightening with silk thread tension knotting or with rivet of wearing in the rivet hole of clamping end got final product.
This vascular clamp has adopted the elasticity medical material, has avoided the drawback of existing vascular clamp metal material to the blood vessel coup injury, and the more general vascular clamp of overall weight is light, and is less to the tractive influence of tissue.The jig arm of hollow forms the structure of a similar air bag, and is balanced to the pressure ratio of blood vessel.This vascular clamp one end is completely fixed, it is fixed that the other end can be worn rivet clasp with medical wire or rivet, avoided the drawback of the easy slippage of existing vascular clamp fully, and can reach adjustment by size control to the knotting dynamics of fixing silk thread and knotting ring to vascular pressure.To sum up,, have characteristics simple in structure, scientific and reasonable, easy to use, can be used for clinical operation and zooperal blood vessel blocking because this utility model has adopted above unique texture.
Description of drawings
Fig. 1 is this utility model structural representation.
Among the figure, 1A, 1B jig arm 2 clamp holder 3A, 3B clamping end 4, wear rivet hole
The specific embodiment
Referring to Fig. 1, this noinvasive elastic vessel anchor clamps have jig arm 1A, the jig arm 1B of two same length, jig arm is one section hollow elastic material, as the medical grade rubber bar or press with silica gel strip etc., one end of two jig arm is fixed together by clamp holder 2, clamp holder 2 can be integrally formed with jig arm, also can be that discrete item adopts powerful viscose glue or rivet to combine with two jig arm to reach the effect that combines and seal the jig arm port, the other end of jig arm is clamping end 3A, 3B, wear rivet hole 4 on the clamping end, be used for threading and fix, or riveted and fixed.So the vascular clamp that forms is the folder shape structure of two airtight similar strips " air bag " linking together of one one end.
The concrete step of using is as follows: run into the blood vessel that needs blocking-up during operation, routinely the blood vessel surrounding tissue is separated, blood vessel is included in the middle of jig arm 1A, the 1B of elastic vessel folder, strain the fixedly silk thread of clamping end 3A, 3B gradually, observing does not have in the distal vessels to begin knotting behind the blood flow, carries out next step operating procedure then, after operation is finished, the silk thread of cutting off clamping end 3A, 3B can unclamp vascular clamp, recovers blood flow.
The effect of this vascular clamp is a blocking blood flow, according to the object of operation and the vessel size of blocking-up, selects the vascular clamp of appropriate size to get final product.
