Puncture needle and wound stitching device

Abstract

The invention provides a puncture needle and a wound stitching device, and relates to the technical field of medical equipment. The puncture needle comprises a puncture needle main body, an operationportion used for operation, and an insertion portion used to insert into a tissue. The puncture needle main body comprises a first pushing piece, a second pushing piece, and a shaft lever. The shaft lever is provided with an internal cavity. A threading needle is used to fix a suture line on the insertion portion, and through taking the puncture needle out from an external sleeve, stitching of a wound is realized, and the stitching does not need rivets. The puncture needle can satisfy a laparoscopic surgery, and would not reserve rivets in an abdominal cavity in stitching. The puncture needleand the wound stitching device just stitch through a suture line, and improve security, prevent rivets from falling into an abdominal cavity, and prevent rivets from hurting a human body. A supportingplate of the insertion portion can be unfolded, and thus the puncture needle can fix the suture line on the position relatively far away from a wound. Thus, after the suture line passes through a fascia layer, stitching effect is better.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a puncture needle and a wound suturing device. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. The traditional method of retroperitoneal laparoscopic surgery is to make three small incisions of 1 cm on the patient's waist, each inserting a tube-shaped working channel called "trocar", and all subsequent operations are performed through these three channels; Complete the same steps as op...

Problems solved by technology

[0004] The purpose of the present invention is to provide relief from suturing in the prior art. Both the anchor and the suture are in the human body, and both the anchor and the suture are made of absorbable and degradable materials for the human body; but after suturing, the suture is unexpectedly Torn off, the anchor falls off and falls into the abdominal cavity of the human body. The anchor has a sharp point, which is easy to cause harm to the human body; And after the suture thread passes through the fascia layer, it is very far away from the wound, and the suture effect is poor.
