Elastic chain burst filling hemostatic puncture needle and buckle

Abstract

The invention relates to the field of medical devices, in particular to an elastic chain-type continuous-firing filling hemostatic puncture needle and a buckle. The invention includes a puncture needle, a sampling needle cooperating with the puncture needle and a push rod, and is characterized in that: it also includes a box body and a hemostatic unit storage strip; the box body is provided with a push channel; the upper wall of the box body is provided with a The upper part of the box body is connected to the puncture guide channel in the push channel from top to bottom, and a fixed slot hole is provided on the lower wall of the push channel, and the needle head of the puncture needle extends downward from the bottom of the fixed slot hole and is exposed on the box body. Externally, the rear seat of the puncture needle is clamped in the fixed slot; the hemostatic unit storage bar is provided with storage channels, and each storage channel is arranged at intervals along the length direction of the hemostatic unit storage bar, and the hemostatic unit is arranged in the storage channel. The invention is easy to operate, can continuously fill the hemostatic unit, can ensure that only a single hemostatic unit is fired at a time, and prevents continuous pollution of the hemostatic unit.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an elastic chain-type continuous-firing filling hemostatic puncture needle and a buckle. Background technique [0002] Biopsy is referred to as "biopsy" for short, also known as surgical pathological examination, or "external examination" for short; it refers to taking out diseased tissue from the patient's body by cutting, clamping or puncturing for pathological examination in response to the needs of diagnosis and treatment. technology. This is the most important part of diagnostic pathology. A clear histopathological diagnosis can be made for the vast majority of cases submitted for examination, and it is regarded as the final clinical diagnosis. [0003] After the biopsy puncture examination, the traditional way of hemostasis is to use external compression to stop the bleeding. However, although the compression hemostasis can stop the external bleeding, the sampling site is of...

Problems solved by technology

However, usually a sampling point needs to be filled with 4-6 hemostatic sponges to completely block the hemostasis, which makes the medical staff have to repeatedly perform the filling operation of the hemostatic sponges in the actual operation process, which not only troubles the operation, but also increases the cost. Many operating steps mean that many risks of misoperation are virtually increased, and the push rod for operation needs to be pulled out many times and exposed to the air to increase the risk of infection

[0005] Then, in order to solve the problem of such cumbersome stuffing operation, those skilled in the art thought of using the hemostatic sponge as a "bullet" and designed a gun-shaped hemostatic device similar to a clip structure. Firing" is continuously injected into the site that needs hemostasis. For example, a Chinese patent, the patent number is 201420540467.0, the authorization date is April 15, 2015, and the patent name is "a kind of implant gun for hemostasis unit of interventional puncture needle channel" Promptly disclose a kind of above-mentioned such device

[0006] However, although this implantation gun for the hemostatic unit of the interventional puncture needle can solve the problem of continuous filling of the hemostatic sponge, it still has relatively serious defects. Since the "bullets" in the device "magazine" are closely arranged, Once blood pollutes the hemostatic unit, it is easy to cause continuous pollution of the nearby hemostatic unit, and when hemostasis is performed on other puncture sampling locations, it is easy to transfer tumor cells into the needle channel, causing tumor metastasis

At the same time, we know that the clip-type structure requires the "bullet" fired inside to be rigid to ensure that only one "bullet" is ejected each time it is fired. However, in order to achieve a good hemostatic effect, we The hemostatic unit used must have a certain degree of softness to meet the required adhesion of the filling site, so this kind of hemostatic filling device that uses a "magazine" structure for continuous firing has a fatal flaw-it is difficult to guarantee each firing Insert one and only one hemostatic unit into the filling site
