Puncture assembly with sewing function and puncture outfit

Technical Field

The utility model belongs to the technical field of medical equipment, specifically speaking relates to a puncture assembly and puncture ware with suture function.

Background

Laparoscopic surgery is a newly developed minimally invasive method and is a necessary trend for the development of future surgical methods. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities. The traditional method of the retrolaparoendoscopic surgery is to make three small 1 cm incisions on the waist of a patient, insert a tubular working channel called trocar respectively, and carry out all the following operations through the three channels; and then special lengthened surgical instruments are used for completing the same steps as the open surgery under the television monitoring, so that the same surgical effect is achieved.

Trocars are very important medical devices for laparoscopic surgery, requiring suturing of the wound after surgery. In the process of suturing, the anchor nail and the suture line are both in the human body, and both the anchor nail and the suture line are made of materials which can be absorbed and degraded by the human body; after suturing, the suture line is accidentally pulled apart, the anchor nail falls off and falls into the abdominal cavity of the human body, and the anchor nail has a sharp tip part and is easy to cause injury to the human body; or because the earlier anchor of stylolite degrades, the anchor drops and falls into human abdominal cavity, causes the injury to the human body, therefore how can sew up the wound of postoperative, avoid anchor etc. to drop into the abdominal cavity is the problem that we need to solve.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and preferred embodiments.

The first embodiment is as follows:

as shown in fig. 1 to 4, a puncture assembly having a suturing function includes a puncture unit for performing a puncture operation, and a suturing needle 4 for performing a suturing operation.

Specifically, the puncture unit is from inside to outside including the pull rod 1, puncture awl 2 and the sleeve pipe 3 of establishing of cover in proper order, puncture awl 2 and sleeve pipe 3 are hollow tubular structure, and
