Problems solved by technology

[0005] Previously, the patent "A Bionic Surgical Instrument, Patent No. 200820153783.7" proposed a minimally invasive surgical instrument with 5 degrees of freedom that can rotate the wrist, but in the actual production process of the patent, it was found that its structure was complicated and the process was difficult. Product reliability and durability need to be further improved

Embodiment Construction

[0032] Such as figure 1 , Figure 7 As shown, the present invention includes a head 1, an extension rod 2, a handle 3, a head joint 5, a handle joint 6, an electrode socket 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 head joint 5 , and the handle 3 is fixedly connected to the tail end of the extension rod 2 through the handle joint 6 . Twisting the handle 3 can drive the handle joint 6, and at the same time, the head joint 5 also produces a corresponding bending action.

[0033] Such as figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 As shown, the joint transmission system is composed of a head joint, 5 handle joints 6 and a transmission wire 9, wherein the two joints are composed of joint plates 10 connected in series, one end of the joint plate 10 is a plane, and the other end is...

Abstract

The invention discloses a rotatable wrist minimally-invasive electrode. The electrode comprises a head, an extension rod, a handle and two joints, wherein the head can complete the activities of five degrees of active freedom, is closer to the functions of a human wrist, and can complete the actions and surgeries which are difficultly completed and even cannot be completed by the certain traditional minimally-invasive surgical instruments; and on the other hand, the handle can perceive the pressure of a working area of the head to a certain degree, and provides certain basis for distinguishing tissues, organs, tumors and calculi for an operator.

Description

technical field [0001] The invention relates to a minimally invasive surgical instrument, in particular to a rotatable wrist minimally invasive electrode. 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 ...
