Problems solved by technology

However, in atrial septal puncture, precise control of the puncture position is required to avoid damage to the heart due to accidental puncture of surrounding tissues
[0003] However, the existing puncture needles cannot be bent, so it is easy to scratch the tissue during the puncture operation, and the puncture is not precise enough and time-consuming

Embodiment Construction

[0089] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0090] First of all, in the field of interventional medicine, the end of the instrument close to the operator is usually called the proximal end (ie, the operation end), and the end of the device away from the operator is called the distal end (ie, the insertion end). Specifically, the distal end refers to the end of the instrument that can be freely inserted into the animal or human body. The proximal end refers to the end that is op...

Abstract

The invention discloses a bending-adjustable puncture needle and a puncture system. The bending-adjustable puncture needle comprises a puncture head and a bending-adjustable sleeve assembly connected with the puncture head in a sleeving mode. The puncture head is used for puncturing a tissue body; an adjustable bending section is arranged at the far end of the adjustable bending sleeve assembly, the far end of the puncture head is exposed out of the adjustable bending section, and the near end of the puncture head is fixed to the far end of the adjustable bending section. The bending-adjustable cannula assembly comprises multiple layers of tube bodies with the bending-adjustable function, the bending-adjustable puncture needle further comprises traction pieces arranged among the multiple layers of tube bodies with the bending-adjustable function, and the far end of each traction piece is fixed to the puncture head or the bending-adjustable section. Due to the fact that the adjustable bending puncture needle can drive the puncture head and the adjustable bending sleeve assembly to freely adjust the direction through the traction piece after entering the body of a patient, the puncture head can be more accurately aligned with the target tissue to be punctured, the situation that the adjustable bending puncture needle hurts an access of an in-vivo puncture operation is avoided, and puncture is more accurate and rapid.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an adjustable puncture needle and a puncture system. Background technique [0002] With the rapid development of interventional equipment and equipment, the application of cardiac interventional therapy has become more and more extensive, which makes atrial septocentesis more widely used. In transseptal puncture, a catheter is usually used as an adjunct instrument for interventional procedures to puncture the atrial septum. However, in atrial transseptal puncture, precise control of the puncture position is required to avoid the problem of accidental puncture of surrounding tissue and damage to the heart. [0003] However, the existing puncture needle cannot be bent, so that the tissue is easily scratched during the puncture operation, and the puncture is not accurate and time-consuming. SUMMARY OF THE INVENTION [0004] In view of this, the present invention prov...
