Thoracoabdominal cavity small incision suture assist device

Abstract

The invention discloses a thoracoabdominal cavity small incision suture assist device. The device comprises a traction unit, a connecting rod and an operation unit, wherein the connecting rod comprises a connecting rod first end and a connecting rod second end which are located in the extending direction of the connecting rod; the traction unit is of a hard structure arranged at the connecting rodfirst end; the operation unit is arranged at the connecting rod second end; the traction unit is movably connected with the connecting rod; the traction unit moves relative to the connecting rod to enable the traction unit to have at least two switchable locking states; the operation unit is connected with the traction unit to control the traction unit to be switched and locked between the two locking states; in the first locking state, the traction unit extends out two traction ends towards the peripheral side of the connecting rod, and the traction ends are arranged towards the operation unit; and in the second locking state, the traction unit is integrally distributed in the axial direction of the connecting rod, and the overall size is smaller than or equal to the circumferential sizeof the connecting rod. The thoracoabdominal cavity small incision suture assist device is convenient to operate and beneficial to precise suture.

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
