Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0041] Such as Figure 1 to Figure 6 As shown, the present invention provides a disposable self-adaptive puncture tear-off sheath, including a sheath tube 1, a tube plug and a tube base 3, wherein: the tube base 3 is assembled by two tearable parts, and the tube base 3 is provided with an accommodation cavity; each tearable part is provided with a pipe plug that communicates with the accommodation chamber; the upper end of the sheath tube 1 enters the accommodation chamber from the lower port of the acc...

Abstract

The invention provides a disposable self-adaptive puncture avulsion sheath. The sheath comprises a sheath canal, canal plugs and a canal seat, the canal seat is formed by splicing two tearable parts, and a containing cavity is formed in the canal seat; the canal plug communicated with the containing cavity is arranged on each tearable part; the upper end of the sheath canal enters the containing cavity from a lower port of the containing cavity and is fastened through the canal plugs; and the top of the canal seat is of a Luer taper structure. By adopting the structure that the sheath canal is naturally cracked, the problem that the sheath canal needs to be punctured and replaced for many times when puncture needles and ablation needles of different models are used is solved, and puncture and ablation positioning is more convenient and efficient. The canal seat is connected with a puncture needle Luer taper, so that the stress is uniform and stable in the puncture process. The tail of the sheath canal shrinks and is in smooth transition to be attached to the puncture inner needle, puncture resistance is conveniently reduced, and puncture is facilitated. A canal seat groove and a canal seat groove buckle are fastened, so that the problem of mistaken tearing is solved. The sheath canal is fixed by pressing and riveting the canal plugs and the canal seat, so that the problem that the sheath canal is not firmly fixed is solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable self-adaptive puncture and tear-off sheath. Background technique [0002] The tearable sheath currently used in interventional therapy is composed of a tearable sheath seat and an expansion tube. The whole assembly is inserted into the human body. After the expansion tube exits the human body, the catheter enters the human body from the sheath tube. The sheath tube can be torn along the central axis without Exit from the back of the catheter, which facilitates the intubation process, and the tear sheath is the main medical device to ensure the smooth and safe entry of the catheter into the blood vessel and body. [0003] The existing tearable sheath has problems such as inconvenient puncture and ablation positioning. [0004] The invention patent of the patent document CN210698456U discloses a tearable sheath with an outer locking turnbuckle, which includes a tearable...
