Multi-degree-of-freedom laparoscope surgical instrument

Abstract

The invention discloses a multi-degree-of-freedom laparoscope surgical instrument in the field of surgical instruments. The multi-degree-of-freedom laparoscope surgical instrument comprises a device body, wherein the device body comprises a handle, a rotary rod, a movement device and clamping plates; one side of the handle is provided with the rotary rod; the clamping plates are arranged on the top end of the other side of the rotary rod; the movement device is arranged on the outer side surface of the rotary rod; a rotary motor structure is arranged in the handle; in addition, the output end of the rotary motor structure is welded and fixed with one side of the rotary rod; one end, which is far away from the rotary rod, of the handle is provided with a small air pump; the tail end of the other side of the rotary rod is movably fixed on the inner side of a top block; the outer side surface of the top block is movably fixedly provided with the clamping plates; the inner side surface of each clamping plate is provided with clamping teeth; the middle of the top end of each clamping plates is provided with a groove and can carry out multiple-angle clamping so as to realize a multi-degree-of-freedom effect; and arranged first telescopic rods and the arranged rotary rod structure can fix the appointed position by each clamping plate, the opening angle of each clamping plate can be controlled by a user, and a use range is enlarged.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a multi-degree-of-freedom laparoscopic surgical instrument. Background technique [0002] Minimally invasive surgery is the most cutting-edge development direction of medical science and technology today. Minimally invasive surgery represented by laparoscopic surgery has gradually replaced traditional laparotomy. After more than 20 years of development, the technique of laparoscopic minimally invasive surgery has gradually matured. Because of its small surgical trauma, mild postoperative pain, short hospital stay, and good cosmetic effect, it has been widely used and satisfied in clinical practice. Effect. Conventional laparoscopic surgery is performed through multiple (3-5) tiny (5-12mm) incisions. With the enrichment of clinical experience and the advancement of engineering technology, the concept of single-port laparoscopic surgery has recently been proposed. Compared wit...

Problems solved by technology

[0004] The object of the present invention is to provide a multi-degree-of-freedom laparoscopic surgical instrument. The user first holds the handle, electrically connects the device body to an external power supply, and then starts the rotating motor in the handle through a button, and the rotating motor drives the rotating rod to perform Rotate, the mobile device meshed with the outside will move to one side, if it moves to the right, the first telescopic rod will drive the clamp to expand outward, open the jaw, and clamp the designated position, and the inner side of the splint is equipped with The clamping tooth structure can be clamped stably to avoid skewed instability. At this time, the user can extend the order of the first telescopic rod by activating the telescopic switch, and then close the splint for clamping, and move to the left When it is opposite to the above-mentioned structural action, it can improve the stability of clamping. When objects in different directions need to be clamped, the user can drive multiple sets of second telescopic rods through the pneumatic switch on the handle to move multiple sets of After the top of the second telescopic rod stretches out, the six groups of second telescopic rods can shrink and support at the same time. Since the fixed blocks fixed at the bottom and the top are different, each group of second telescopic rods will extend or retract in this direction. , when stretched out, the top plate on the top will be rotated outwards, and then the splint will be rotated, the splint can be rotated to achieve multi-degree-of-freedom operation, which is convenient for doctors to use. Clamping, to achieve the effect of multiple degrees of freedom to solve the problem that the push rod proposed in the above background technology can only move along the axial direction of the instrument, and cannot provide a single degree of freedom of rotation
