Description

Protective sheath of blood vessel blocking forceps for aortic surgery

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a protective sheath of a blood vessel blocking forceps for an aorta operation.

Background

In the operation of heart great vessels, a blood vessel blocking forceps is usually needed to block important blood vessel branches, and the existing blood vessel blocking forceps are made of metal materials, are hard in texture and good in blocking effect, but cannot avoid cutting damage of forceps clamps on the vessel wall. Especially in aortic dissection/aneurysm operation, the diseased blood vessel is extremely fragile and thin, and is often attacked by more serious secondary cutting injury after being blocked by a clamp, sometimes even threatening the life of a patient.

Chinese patent documents: CN200420120966.0, application date 20041212, patent names: a sleeve type vessel blocking forceps. A pair of blood vessel blocking forceps for clamping plastic tube without damage is composed of a pair of front arms, a pair of silicone tubes sleeved to said front arms, and a pair of clamping forceps for clamping plastic tube.

Chinese patent documents: CN200720158230.6, application date 20071129, patent names: a pressure equalization vascular clamp. The utility model discloses a pressure-balanced vascular clamp, this vascular clamp include left spring exerciser, holder, right spring exerciser, left and right spring exerciser is an elastic steel wire and twines the back both ends alternately in the middle of the round respectively and links to each other with the holder, for the protection blood vessel does not receive the damage, wraps up the elastic plastic pipe of one deck utensil on the holder upper and lower jaw. Because the left spring device and the right spring device have the same elasticity, the pressures distributed on the upper jaw and the lower jaw of the clamp are equal.

In the sleeve type vessel occlusion forceps disclosed in the patent document CN200420120966.0, the two forearms of the forceps are sleeved with appropriate silicone tubes, so that the forceps are prevented from directly contacting the plastic tube when the plastic tube is clamped, and the plastic tube is not broken or fractured; in the patent document CN200720158230.6, the upper and lower jaws of the clamp are wrapped with a layer of elastic plastic tube, and the left and right elastic devices have the same elasticity, so that the pressure at the contact surface between the jaws of the clamp and the blood vessel is balanced and consistent, and the blood vessel is not damaged and does not slip off. However, there is no report on a protective sheath of a vessel blocking forceps for aortic surgery, which can reduce unnecessary iatrogenic secondary vessel wall injuries in great cardiac vascular surgery and can prevent the vessel blocking forceps from slipping off a blood vessel.

In view of the above, there is a need for a protective sheath of a vessel blocking forceps for aortic surgery, which can reduce unnecessary iatrogenic secondary vessel wall injuries during great cardiac vascular surgery and can prevent the vessel blocking forceps from slipping off the vessel.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide a protective sheath of a blood vessel blocking clamp for aorta operation, which can reduce unnecessary iatrogenic secondary blood vessel wall injury in the great cardiac vascular operation and prevent the blood vessel blocking clamp from slipping off from a blood vessel.

In order to achieve the purpose, the utility model adopts the technical scheme that:

a protective sheath of a vessel blocking clamp for aorta operation comprises a protective sheath body; the protective sheath body is made of dark soft silica gel, the outer surface clamping end is provided with longitudinal soft teeth, and the inner surface is planar; the protective sheath body is of a tightening type opening structure.

As a preferable technical scheme, the protective sheath body is designed according to the section shape of the existing metal vessel occlusion clamp, and has various sizes.

The utility model has the advantages that:

1. the protective sheath body adopts the silica gel material, and the texture is pliable and tough, has better elasticity, and the internal surface be planar can ensure and metal pincers between sufficient coefficient of friction avoid the slippage, can ensure again that the clamp position is airtight and do not receive the cutting damage, and dark design, in case the protective sheath body drops to internal in the art, can in time discover and take out.

2. The soft tooth of column of protection sheath body outside surface exposed core is equipped with, and the frictional force between multiplicable and the vascular wall when avoiding the centre gripping, the vascular slippage.

3. The front end structure of the forceps is matched with that of the clinical blood vessel blocking forceps in structure, the protective sheaths in various models can be designed according to the blocking forceps in different types, the protective sheaths can be conveniently and firmly sleeved on the blood vessel blocking forceps in different models, and the practicability is high.

4. According to the utility model, the protective sheath body made of silica gel is sleeved at the front end of the clinical vessel occlusion forceps, and is ensured to be firm and not easy to slide by virtue of the contraction force and the larger friction coefficient between the silica gel and metal.

5. When the blood vessel blocking forceps sleeved with the protective sheath body clamp the blood vessel, the tension of the blood vessel blocking forceps on the blood vessel wall can be obviously reduced due to the elasticity of the silica gel material, and unnecessary iatrogenic secondary blood vessel wall injury in the heart great vessel operation is reduced.

6. The design of the protective sheath body through the tightening type opening can increase the friction force between the protective sheath body and the blood vessel blocking forceps, ensure the stability and prevent the slippage.
