Abstract

The utility model discloses an improved medical vascular clamp which comprises an elasticity handle, elasticity arms and clamping pieces. The elasticity handle is formed by an elastic steel wire winding into a circle; two ends where the elastic steel wire extends out form the arc-shaped elasticity arms; the two elasticity arms are provided with the clamping pieces directly contacting with a blood vessel, and the clamping pieces are hollow plastic cement pipes. The elasticity handle and the elasticity arms are both made of steel wires with very strong elasticity, thereby the elasticity of the vascular clamp can be improved; the clamping pieces are made of plastic cement material which has certain elasticity, and meanwhile, since the clamping pieces are hollow, the elasticity is further enhanced. On the one hand, blood vessels can not be damaged, and on the other hand, the purpose of pressure equalizing can be achieved.

Description

A kind of improved medical blood vessel folder

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of vascular clamp of blocking blood flow.

Background technology

Vascular clamp is the apparatus of using always in surgical operation, in order to clamp the blood vessel blocking blood flow, is convenient to operation technique.The blood vessel that uses accompanies varied now, to adapt to the needs of different blocking-up vascular flows, but the vascular clamp that uses mainly contains two kinds from the material branch at present, a kind ofly make with metal material, the vascular clamp that metal material is made has the advantage that elastic force is big, folder power is strong, and shortcoming is that metal clip is faced by the folder blood vessel and often caused damage, and particularly long-time clamping forms thrombosis to arterial intima, volume is heavy besides, and blood vessel is involved greatly; The 2nd, make with nonmetallic materials, as medical plastic cement vascular clamp, it is little to have a volume, lightweight advantage, but exist elastic force little, the problem of chucking power difference.

Summary of the invention

Advantage of the present utility model is exactly the problem at existing metallic blood vessel presss from both sides and medical plastic cement vascular clamp in use exists, a kind of improved novel vascular folder is provided, this follow-on vascular clamp has elastic force big, isostasy, in light weight, the not advantage of injured blood vessel.

The purpose of this utility model is to realize like this, this improved medical blood vessel folder comprises elastic force handle, elasticity arm, holder, described elastic force handle forms for rubber-like steel wire winding one circle, the two ends that its elasticity steel wire stretches out form the arc elasticity arm, the holder that directly contacts with blood vessel is housed on described two elasticity arms, and described holder is the plastic cement pipe of hollow.

Elastic force handle and elasticity arm are to have the very steel wire of strong elasticity, therefore can improve the elasticity of vascular clamp; Holder is a plastic cement material, and itself just has certain elasticity, again owing to be hollow, has more strengthened this elasticity simultaneously, and one side is injured blood vessel not, can reach the purpose of isostasy on the other hand.

The beneficial effects of the utility model are: compare with the vascular clamp of simple metal material, have little, the lightweight advantage of blood vessel injury; Compare with the vascular clamp of pure plastic cement material, resilient beam, chucking power is big.The shortcoming of having evaded simple metal and pure plastic cement vascular clamp.

Description of drawings

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing

Fig. 1 is a structural representation of the present utility model

Among the figure: 1, elastic force handle 2, elasticity arm 3, holder

The specific embodiment

As shown in Figure 1, this improved medical blood vessel folder comprises elastic force handle 1, elasticity arm 2, holder 3, elastic force handle 1 forms for rubber-like steel wire winding one circle, the two ends that its elasticity steel wire stretches out form arc elasticity arm 2, article two, the holder 3 that directly contacts with blood vessel is housed on the elasticity arm 2, and holder 3 is the plastic cement pipe of hollow.

Elastic force handle 1 and elasticity arm 2 are rubber-like steel wires, therefore can improve the elasticity of vascular clamp; Holder 3 is plastic cement materials, and itself just has certain elasticity, again owing to be hollow, has more strengthened this elasticity simultaneously, and one side is injured blood vessel not, can reach the purpose of isostasy on the other hand.

Claims

1, a kind of improved medical blood vessel folder, this vascular clamp comprises elastic force handle, elasticity arm, holder, it is characterized in that a circle forms described elastic force handle for the rubber-like steel wire twines, the two ends that its elasticity steel wire stretches out form the arc elasticity arm, the holder that directly contacts with blood vessel is housed on described two elasticity arms, and described holder is the plastic cement pipe of hollow.
