Suturing auxiliary device for small incision in thoracoabdominal cavity

Abstract

The invention discloses a small thoracoabdominal incision suturing assistant, which includes a pulling unit, a connecting rod and an operating unit, the connecting rod includes a first end of the connecting rod and a second end of the connecting rod located in the extending direction thereof, and the pulling unit is set to On the hard structure at the first end of the connecting rod, the operating unit is arranged at the second end of the connecting rod; wherein, the pulling unit is movably connected with the connecting rod, and the pulling unit moves relative to the connecting rod so that the pulling unit includes at least two switchable In the locked state, the operating unit is connected with the pulling unit to control the switching and locking of the pulling unit between the two locking states; wherein, in the first locked state, the pulling unit extends two pulling units toward the peripheral side of the connecting rod. end, and the pulling end is hooked to the operating unit; in the second locked state, the pulling unit is distributed along the axial direction of the connecting rod as a whole, and the overall size is smaller than or equal to the circumferential size of the connecting rod. The suturing aid for small incisions in the thoracoabdominal cavity of the present invention is easy to operate and contributes to precise suturing.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a suturing aid for small incisions in the thoracoabdominal cavity. Background technique [0002] Thoraco-laparoscopic surgery is an advanced stage of surgery and an inevitable trend in the development of future surgical methods. At present, some small incisions after thoracic and laparoscopic surgery need to be sutured. The incisions made during surgery are multi-layered. In order to meet the requirements of aesthetics and reduce pain for patients, generally speaking, the incision on the surface of the skin is small; but in order to meet the needs of surgery, the incision on the deep layer is relatively large; for example, a small incision of 3 cm on the surface may correspond to a deep incision. It will reach 5cm-6cm. [0003] Due to the structural characteristics of small incisions, the following problems exist in the existing small incision suture proces...

AI Technical Summary

Problems solved by technology

[0003] Due to the structural characteristics of the small incision, there are the following problems in the existing small incision suture process: 1. Poor comprehensive vision, 2. Poor positioning of layers, 3. It can be accurately touched by hand, but it is difficult for ordinary instruments to do so.

During the operation, generally 2 to 3 people are required to operate multiple instruments at the same time to complete the suture operation; the multi-person operation has the technical problems of taking up a lot of space and poor coordination

Due to the existence of the above technical problems, it is difficult for the surgeon to see the various layers of tissue and suture accurately, which makes it difficult to suture small incisions

At present, there is no clinical auxiliary device specially used for multi-layer suturing of small incisions. In the suturing operation after thoracic and laparoscopic surgery, each layer needs to be sutured firmly, and there is currently no surgical device specially used for precise suturing of each layer
