specific Embodiment approach 1

[0018] Specific implementation mode one: combine Figure 1-Figure 6 Explain that the intra-abdominal magnetic anchor clamping surgical robot for minimally invasive surgery in this embodiment includes a mechanical mechanism unit and an electronic control unit;

[0019] The mechanical structural unit includes a housing 1, a first worm 2, a second worm 3, a worm wheel 4, a rack 5, a permanent magnet 6, a suspension base 7 and a clamping mechanism; the clamping mechanism includes a third motor 13, a screw pair 14. The first connecting rod 15, the second connecting rod 16, the third connecting rod 17 and the pliers 18; the electric control unit includes a first motor 8, a second motor 9, a control circuit module 10 and a wireless transceiver module 11;

[0020] The housing 1 is a hollow body with open ends. The inner wall of the housing 1 is embedded with a control circuit module 10 and a wireless transceiver module 11. The first worm 2, the second worm 3, and the worm wheel 4 are ...

specific Embodiment approach 2

[0027] Specific implementation mode two: combination Figure 1-Figure 2 and Figure 4-Figure 5 Note that the rack 5 in this embodiment is a titanium alloy rack. Such setting reduces the weight of the rack, increases the strength of the rack at the same time, avoids interference to the magnetic field of the magnet, and thus increases the stability of the anchor. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0028] Specific implementation mode three: combination Figure 1-Figure 2 and Figure 4-Figure 5 Note that the modulus of the rack 5 in this embodiment is 0.5. Such setting is convenient and reliable in use. Others are the same as in the first or second embodiment.

Abstract

The invention discloses an intraperitoneal magnetic anchoring and clamping surgical robot for minimally invasive surgery, relates to a robot for minimally invasive surgery and aims at solving the problems that a surgical doctor directly holds a surgical instrument with the hand in the existing abdominal minimally invasive surgical process so that the surgical precision and quality are further affected, and an existing surgical robot is high in cost, large in occupied volume and relatively poor in movement freedom. The intraperitoneal magnetic anchoring and clamping surgical robot comprises a mechanical structural unit and an electric control unit, wherein the mechanical structural unit comprises a housing, a first worm, a second worm, a worm gear, a rack, a permanent magnet, a suspension base and a clamping mechanism; the clamping mechanism comprises a third motor, a screw pair, a first connecting rod, a second connecting rod, a third connecting rod and pliers; the electric control unit comprises a first motor, a second motor, a control circuit module and a wireless transceiving module; and the control circuit module and the wireless transceiving module are embedded on the inner side wall of the housing, and the first worm, the second worm, the worm gear, the rack, the first motor, the second motor and the clamping mechanism are arranged in the housing. The intraperitoneal magnetic anchoring and clamping surgical robot disclosed by the invention is used for minimally invasive surgery.

Description

technical field [0001] The invention relates to a robot for minimally invasive surgery. Background technique [0002] Compared with ordinary open surgery, minimally invasive surgery has the advantages of less trauma, less blood loss, less pain, lower risk of surgical infection, shorter postoperative recovery time, and smaller postoperative scars, which is more in line with people's pursuit of quality of life and beauty , so it has been unanimously recognized in the field of surgical operations, and is widely used in surgical operations in many hospitals at home and abroad. [0003] However, some aspects of the existing minimally invasive surgery still need to be perfected. For example: when performing some operations on infectious diseases, the doctor directly operates the surgical instrument and contacts the patient, which may cause his own infection; the doctor operates the surgical instrument for a long time, and is prone to fatigue, which affects the accuracy of the ope...
