Problems solved by technology

Whether the above three measures are monitored by equipment or checked repeatedly, it will undoubtedly increase the operation time and increase the cost of the operation. Two or more punctures into the lesion cavity will easily cause multiple traumas to the patient and prolong the recovery time of the patient. , and the increase of equipment will undoubtedly increase the number of medical staff and the medical expenses of patients. In the case of a large number of the same operating tables in one day, it is obviously not conducive to improving the efficiency of the operation.

Embodiment 1

[0051] In a typical implementation of the present application, such as figure 1 and figure 2 As shown, a needle tip displacement-proof puncture indwelling needle for the treatment of vascular malformation sclerosing includes: an indwelling needle sleeve with a puncture tube inside, and the end of the puncture tube is sharp to facilitate entry into the vessel; an elastic bag 8. The elastic pouch 8 is set outside the front end of the indwelling needle cannula 9, and the elastic pouch 8 is connected to the pouch pipeline, and the pouch pipeline is set on the side of the indwelling needle cannula 9 or sleeved on the indwelling needle cannula 9 Externally, the elastic pouch 8 is filled with liquid and expanded to effectively prevent the end of the puncture tube 10 from protruding from the pathological vascular malformation cavity; one end of the sclerosing agent injection tube 2 communicates with the indwelling needle sleeve through the sclerosing agent injection port.

Embodiment 2

[0069] In this embodiment, a grasping handle 14 is provided on the top of the puncture tube, such as Figure 4 As shown, it is convenient to take out the puncture tube 10 by grasping the handle 14, and at the same time, it is also convenient to hold the puncture indwelling needle during operation. contact settings.

[0070] The specific operation steps are as follows:

[0071] 1) The puncture tube enters the human skin or mucous membrane through the sharp end, and enters the lesion cavity after passing through a layer of normal tissue;

[0072] 2) Inject physiological saline into the elastic pouch through the pouch pipeline, so that the elastic pouch opens and increases in volume, so as to ensure the needle tip position of the puncture indwelling needle;

[0073] 3) Take out the puncture tube 10 by grasping the handle 14, and the stopper 4 returns to its original state;

[0074] 4) Draw out the liquid in the cavity through the indwelling needle cannula and the sclerosing ag...

Abstract

The invention discloses an indwelling needle which is capable of preventing needle tip displacement and puncture and applicable to vascular malformation sclerosis treatment and a method thereof. The indwelling needle and method solve the problems that the needle tip of the indwelling needle is prone to come out of lesion lacunas and the existing method requires much monitoring equipment. The indwelling needle can quickly guarantee the stabilization of the position of the needle tip and is simple to operate. According to the technical scheme, the indwelling needle includes an indwelling needlecasing with a built-in puncture tube which has a sharp end portion in order to pierce through vessels, an elastic sack arranged outside the front end of the indwelling needle casing and connected witha sack pipeline, wherein the sack pipeline is arranged in one side of the indwelling needle casing or sleeves the outside of the indwelling needle casing, and the elastic sack swells when it is filled with liquid so as to effectively prevent the end portion of the puncture tube from coming out of the diseased vascular malformation lacunas, and a sclerosing agent injection tube, one end of which is communicated with the indwelling needle casing through a sclerosing agent injection port.

Description

technical field [0001] The invention relates to the field of medical treatment of vascular malformation sclerosing, in particular to a needle point displacement-preventing puncture retention needle and a method for treating vascular sclerosing. Background technique [0002] Vascular malformation is a malformation that occurs during the development of the vascular system or lymphatic system. It is mainly manifested as deformed and enlarged lumen of blood vessels or lymphatic vessels, which are filled with blood or lymph fluid. The treatment is sclerotherapy as the preferred treatment. [0003] Sclerotherapy is to inject sclerosing agent into the lumen of deformed and enlarged blood vessels or lymphatic vessels, so that the endothelium of blood vessels or lymphatic vessels and the subendothelial tissue will be inflamed, adhered and finally scarred, and the malformed blood vessels or lymphatic lumens will be finally atresiad. The specific operation method is to puncture the pun...
