Double-bend thoracoscopic surgery set instrument

Abstract

A double-bend thoracoscopic surgery set instrument comprises a surgical instrument used for being matched with one another to complete thoracoscopic surgery, the surgical instrument is sequentially divided into a handle part, a rod body and a head part, and the rod body is bent towards any side in the horizontal direction to form a first bent section; the end, away from the rod body, of the head is bent towards any one of the upper side and the lower side of the horizontal plane where the rod body is located to form a second bent section. By the adoption of the technical scheme, the surgical instrument obtains a larger movement range in the thoracic cavity, large-amplitude wrist rotation when an operator uses the instrument is reduced, and surgical smoothness is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of medical instruments, in particular to a double-curved thoracoscopic surgery set instrument. 【Background technique】 [0002] Thoracoscopic surgery is a new technique of minimally invasive thoracic surgery that uses modern camera technology and high-tech surgical equipment to complete complex intrathoracic surgery under tiny incisions. It is the future development direction of thoracic surgery. [0003] During thoracoscopic surgery, 2-3 holes need to be made on the chest wall to separate blood vessels and trachea, and to remove lung lobes. The instruments used in the operation, including endoscope, lung lobe forceps, aspirator and needle holder, often need to enter and leave the chest cavity through a 2-4cm incision. Since the instruments are linear, they are easy to interfere with each other during the operation, which is extremely difficult. It greatly affects the operation of the operator, especially ...

AI Technical Summary

Problems solved by technology

The instruments used in the operation, including endoscope, lung lobe forceps, aspirator and needle holder, often need to enter and leave the chest cavity through a 2-4cm incision. Since the instruments are linear, they are easy to interfere with each other during the operation, which is extremely difficult. It greatly affects the operation of the operator, especially when suturing under the endoscope, due to the limitation of the shape of the instrument, the position of the incision and the angle of the sutured tissue, it is often difficult to suture, which increases the complexity and complexity of the operation. difficulty

[0004] However, in the existing double arthroscopic head end or shaft with a curvature, there is still a limitation in the scope and angle of movement of thoracoscopic surgical instruments in the chest cavity, and the surgical operation can only be completed with a relatively large arc of wrist rotation during the operation. Increased the difficulty of the operation; at the same time, there are still shortcomings of mutual interference between instruments, resulting in limited cross-use between instruments and reduced flexibility
