Problems solved by technology

[0005] Previously, the patent "A Bionic Surgical Instrument, Patent No. 200820153783.7" proposed a bendable minimally invasive surgical instrument with 5 degrees of freedom, but in the actual production process of the patent, it was found that its structure was complicated and the process was difficult. The reliability and durability of the

Embodiment Construction

[0027] Such as figure 1 , Figure 5 As shown, the present invention includes a head 1, an extension rod 2, a handle 3, a joint 4 and two sets of internal transmission systems—the joint transmission system and the head opening and closing transmission system. The head 1 is fixedly connected to the front end of the extension rod 2 through the joint 4, and the handle 3 is fixedly connected to the tail end of the extension rod 2 through the handle base 7. The bending action of the joint 4 can be realized by adjusting the left and right bending adjustment rotor 5 and the up and down bending adjustment rotor 6 .

[0028] Such as figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, the joint transmission system is composed of a joint 4, a transmission wire 9 and two adjusting rotors, wherein the joint 4 is composed of several joint plates 9 connected in series, one end of the joint plate 9 is a plane, and the other end is provided with two slopes 12, The center i...

Abstract

The invention discloses a flexible minimally invasive apparatus which comprises a head, an extension rod, a handle, a joint and a regulating rotor, wherein the head can make a motion of 5 degrees of motion freedom, thereby being more approximate to the function of a human wrist and being capable of completing motions and surgery which are difficult to implement or even can not be implemented by using the traditional minimally invasive surgery apparatuses. On the other hand, the handle can sense the pressure of the work area of the head to a certain extent, thereby providing a certain reference for surgeons to distinguish tissues, organs, tumors and calculi.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a bendable minimally invasive instrument. Background technique [0002] Since French doctors successfully performed the first laparoscopic cholecystectomy in 1987, minimally invasive surgery represented by laparoscopic surgery has experienced more than 20 years of development and has formed a relatively independent discipline, deriving thoracoscopy and pelvic endoscopy. , Arthroscopy and a series of minimally invasive surgeries. At present, minimally invasive surgery has become the most cutting-edge and most complex technology in surgery. A large number of advanced equipment, materials and instruments were first applied in this field. Minimally invasive surgery is also an important direction for the development of surgery in the 21st century. [0003] Minimally invasive surgery refers to making several perforations on the surface of the human body, and inserting the en...
