Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1As shown, the present invention includes a multi-degree-of-freedom surgical tool 10 and a surgical tool drive unit 20 . Wherein, the multi-degree-of-freedom surgical tool 10 includes a flexible continuum mechanical arm 30 and a mechanical arm driving device 40 (such as figure 2 , image 3 shown).

[0029] Such as Figure 4 As shown, the flexible continuum manipulator 30 of the present invention includes a first segment continuum 301 , a second segment continuum 302 and a surgical forceps 303 . The first segment continuum 301 includes four first structural bones 304 arranged in parallel at equal intervals, a plurality of first spacer discs 305 distributed at equal intervals, and a first fixed plate 306, wherein the rear ends of the first structural bones 304 are connected to the mechanical The arm driving device 40 is conne...

Abstract

The invention relates to an electrically-driven multi-degree-of-freedom transurethral surgery system comprising a multi-degree-of-freedom surgical tool and a surgical tool driving unit, the multi-degree-of-freedom surgical tool comprises a flexible continuous body mechanical arm and a mechanical arm driving unit; the flexible continuous body mechanical arm comprises a first-section continuous body, a second-section continuous body and a surgery clamp; the first-section continuous body comprises four equidistantly and parallelly arranged first structural bones, multiple equidistantly distributed first spacing discs and a first fixing piece, the rear end of each first structural bone is connected with the mechanical arm driving unit, and the front end of each first structural bone sequentially penetrates the first spacing discs to be fixedly connected with the first fixing piece; the second-section continuous body comprises four equidistantly and parallelly arranged second structural bones, multiple equidistantly distributed second spacing discs and a second fixing piece, the rear end of each second structural bone is connected with the mechanical arm driving device, and the front end of each second structural bone sequentially penetrates the first spacing discs, the first fixing piece and the second spacing discs to be fixedly connected with the second fixing piece.

Description

technical field [0001] The invention relates to a transurethral electrically driven multi-degree-of-freedom operation system, which belongs to the field of medical devices. Background technique [0002] In the modern medical field, minimally invasive surgery has achieved success in reducing patients' postoperative pain and complications, shortening hospital stay, and improving postoperative scar conditions. In this field, the da Vinci porous laparoscopic surgical robot developed by Intuitive Surgical, which has been successfully commercialized, can meet the requirements of various minimally invasive surgeries. However, with the maturity of medical technology and the higher and higher requirements of patients, there has been naturalorifice trans-luminal endoscopic surgery (NOTES), which is characterized by the fact that no incision is required, and surgical instruments need to pass through a long and narrow cavity. The complex human cavity then arrives at the surgery departm...
