Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] like figure 1 As shown, the embodiment of the present invention provides a bendable surgical device, which includes a shaft part 1, a bending part 2, and a front end surgical device 3 that are sequentially connected axially. The bendable surgical device also includes a bending drive structure 4 and a front end The operation driving structure 5, the bending driving structure 4 and the front end operation driving structure 5 are both axially penetrated in the rod body part 1 and the bending part 2, and the bending driving structure 4 and the rod body Part 1 and the bending part 2 are all flexibly connected, the bending driving structure 4 is used to drive the bending...

Abstract

The invention relates to the technical field of surgical and medical equipment, and discloses a surgical device capable of being bent. The device comprises a rod part, a bent part and a front-end surgical device body which are sequentially connected through shafts. The surgical device capable of being bent further comprises a bending driving structure and a front-end surgery driving structure. The rod part, the bent part and the front-end surgical device body which are sequentially connected stretch into a wound, the bending driving structure drives the bent part and the front-end surgical device body to be bent together, and meanwhile the front-end surgery driving structure drives the front-end surgical device body to conduct specific operations. The degree of freedom of bending is high, the front-end surgical device body can successfully reach a surgical part, and operations can be conducted in narrow space. Besides, the surgical device is simple in structure, flexible and convenient to operate, stable, capable of generating large operation force and low in cost.

Description

technical field [0001] The invention relates to the technical field of surgical medical instruments, in particular to a bendable surgical device. Background technique [0002] In minimally invasive surgery, the surgeon only needs to open a small incision in the patient to complete the operation. Compared with traditional open surgery, minimally invasive surgery has the advantages of less trauma, faster postoperative recovery, lower recurrence rate, and fewer complications. [0003] Based on the characteristics of small incisions in minimally invasive surgery, the surgical path required by minimally invasive surgery is complicated, and the surgical operation space is narrow, and surgical occlusion areas are often encountered during operation. Therefore, surgical instruments are required to have sufficient wrist degrees of freedom to ensure that the end effector reaches the surgical operation site smoothly. But lack a kind of special instrument that can carry out operation o...
