Description

A kind of vascular clamp

Technical field

The invention belongs to medical instruments field, relate to a kind of vascular clamp.

Background technology

Similar products common on Present clinical are called vascular clamp, ligation clip, ligation vascular clamp etc., be with do not absorb or absorbable biological material disposable injection molded.There is following shortcoming in the clip of these structures: 1, snap close point is single, once there is slippage, clip just can lose locker power, will cause massive hemorrhage and major accident occurs; 2, clip relies on the mode of plane pressurization to flatten blood vessel or pipeline, thus reaches closed effect, and this mode easily seepage occurs; 3, clip both arms can only be produced in disposable injection moulding, and multiple material cannot be used to combine to meet clinical needs, and are therefore restricted utilizing in absorbable material.

The clip that absorbable material is made is the direction of clinical demand, but due to the restriction of material behavior, is difficult to make the clip as not absorbing material.

Summary of the invention

The present invention is directed to the problems referred to above, provide a kind of vascular clamp, this vascular clamp reliable lock is stablized.

According to technical scheme of the present invention: a kind of vascular clamp, it is characterized in that: comprise the first jig arm, the second jig arm, described first jig arm, both the second jig arm one side end are articulated and connected, second jig arm offers groove, both sides, groove front end are respectively to upper formation first guide holder, the second guide holder, first guide holder, both the second guide holders are respectively equipped with projection towards groove side, the locking end of the first jig arm is bent to form puncture tapered end downwards, puncture tapered end both upper ends thereof forms fixed teeth respectively, forms lower fixed teeth inside puncture tapered end; Bottom portion of groove is groove base plate, and groove base plate front end is provided with bottom land tooth; After first jig arm, both the second jig arm are closed, lower fixed teeth lock onto bottom land teeth portion position, and upper fixed teeth is clamped in protruding below.

As a further improvement on the present invention, described first jig arm bottom surface is provided with anti-slop serrations.

As a further improvement on the present invention, the link of described second jig arm offers axis hole, and the link of the first jig arm is provided with convex axle, and convex axle matches with axis hole, realizes the first jig arm, being rotationally connected of the second jig arm.

As a further improvement on the present invention, described first jig arm front end is provided with fixed leg, and the second jig arm front end is provided with lower fixed leg.

As a further improvement on the present invention, after the first jig arm and the second jig arm close, the first jig arm top is stretched out outside groove.。

Technique effect of the present invention is: (1), utilize two independently jig arm, forms chimeric folder and closes structure, make folded blood vessel or pipeline create bending, can improve folder and close effect, effectively solve leakage problems, simultaneously also to preventing gripper slippage from playing a role; (2), fastener system devises the structures of upper and lower 3 lockings of tapered end, effectively can prevent snap close slippage and the risk brought of surrounding tissue filling fixed teeth; (3), two jig arm manufacture respectively, and the structure of then assembling, makes two-arm connecting portion without elasticity, are applicable to the absorbable material manufacture using varying strength.

Fig. 3 is lower fixed teeth locking position schematic diagram in Fig. 1.

Fig. 4 is the structural representation of the second embodiment of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.

In Fig. 1 ~ 4, comprise the first jig arm 1, second jig arm 2, convex axle 3, puncture tapered end 4, upper fixed teeth 5, lower fixed teeth 6, anti-slop serrations 7, axis hole 8, groove 9, projection 10, bottom land tooth 11, upper fixed leg 12, lower fixed leg 13, groove base plate 14, groove first facade 15, groove second facade 16, second guide holder 17, first guide holder 18 etc.

As shown in Fig. 1 ~ 4, the present invention is a kind of vascular clamp, comprise the first jig arm 1, second jig arm 2, described both first jig arm 1, second jig arm 2 side end is articulated and connected, second jig arm 9 offers groove 9, both sides, groove 9 front end are respectively to upper formation first guide holder 18, second guide holder 17, both first guide holder 18, second guide holders 17 are respectively equipped with protruding 10 towards groove 9 side, the locking end of the first jig arm 1 is bent to form puncture tapered end 4 downwards, puncture tapered end 4 both upper ends thereof forms fixed teeth 5 respectively, forms lower fixed teeth 6 inside puncture tapered end 4; Be groove base plate 14 bottom groove 9, groove base plate 14 front end is provided with bottom land tooth 11; After both first jig arm 1, second jig arm 2 are closed, lower fixed teeth 6 lock onto bottom land tooth 11 position, and upper fixed teeth 5 is clamped in below protruding 10.

First jig arm 1 bottom surface is provided with anti-slop serrations 7, and anti-slop serrations 7 can effectively prevent the blood vessel clamped from coming off; The link of the second jig arm 13 offers axis hole 8, and the link of the first jig arm 1 is provided with convex axle 3, and convex axle 3 matches with axis hole 8, realizes being rotationally connected of the first jig arm 1, second jig arm 2.Two jig arm in product of the present invention are two independently parts, can use the absorbable material manufacture of varying strength when producing, and simultaneously compared to traditional one-body molded vascular clamp, in product of the present invention, the connecting portion of two jig arm is also without elasticity.

First jig arm 1 front end is provided with fixed leg 12, and the second jig arm 2 front end is provided with lower fixed leg 13, and upper fixed leg 12, lower fixed leg 13, when performing the operation, facilitate medical personnel to operate vascular clamp of the present invention.

After both first jig arm 1 and the second jig arm 2 are closed, the first jig arm 1 top is stretched out outside groove 9.

The present invention is directed to existing vascular clamp and adopt integral molded plastic molding, the shortcomings causing existing vascular clamp to exist carries out innovative design.Work process of the present invention is as follows: operationally, blood vessel is clamped between the first jig arm 1, second jig arm 2 of product of the present invention, because the first jig arm 1 bottom is pressed in the groove 9 of the second jig arm 2, blood vessel both the first jig arm 1, second jig arm 2 effect under by reliable grip (now, blood vessel is pressed in groove 9, and the compacted part of blood vessel is coated on both sides and the bottom of the first jig arm 1); When first jig arm 1 is pressed in the groove 9 of the second jig arm 2, upper fixed teeth 5 on puncture tapered end 4, lower fixed teeth 6 are respectively at the appropriate section locking in the second jig arm 2, realize 3 lockings, namely two upper fixed teeth 5 to match locking respectively at two projections 10, and lower fixed teeth 6 is locked with bottom land tooth 11 phase.
