Problems solved by technology

[0003] The current laparoscopic surgical instruments are straight, and the distal end cannot be bent, so it cannot achieve the requirement of reaching the target tissue from multiple angles for operation
Although the da Vinci surgical robot achieves flexible bending functions through complex mechanical structures, power systems and computer programs, the high price and huge equipment size make it impossible to popularize and realize commercial operation

Embodiment 1

[0027] like figure 1 and figure 2 As shown, the portable manual surgical robot of the present embodiment includes: the cutter head 11, the shaft 12, and the handle 13,

[0028] The cutter head is connected to the front end of the shaft 12 through the curved joint 14.

[0029] The joint 15 is a hollow hemispherical, located at the joint of the shaft and the handle, the front end of the joint 15 is integrated with the shaft, and the housing of the rear end and the handle 13 rotates through the spherical surface.

[0030] The joint lock switch 16 is disposed on the side of the upper segment of the handle 13, and the position of the thumb can be turned to the handle when the handle is holding the handle.

[0031] The joint locking drive shaft 17 is a L-shaped, the front end is fixed to the joint lock switch 16, and the tail end is fixed to the joint lock ring 18.

[0032] The joint lock ring 18 is located in a spherical space within the joint 15. When the joint lock switch 16 is moved...

Embodiment 2

[0051] like Figure 5 As shown, the portable manual surgical robot of the present embodiment changes the structure of the cutting and rotation of the cutter head 11 on the basis of the first example.

[0052] The cutter rotary hollow shaft 2 is extended down to the cutter head opening and closing lever 20, and the cutter head opening and closing the steel rope 22 is also connected to the cutter head opening and closing lever 20 in the cutter head. The pressing tool head opening and closing lever 20 can drive the cutter head opening and closing shaft 21 and the cutter head in the cutter head in the axial shaft 27, so that the distal cutter head 11 performs opening and closing motion.

[0053] like Figure 5 As shown, a set of tool head rotation transmission gear 33 is mounted at the cutter head rotation shaft 27 and the cutter head rotation drive shaft 25, respectively, located at the position of the cutter head rotation drive shaft and the rotary air mandrel intersection, and meshin...

Embodiment 3

[0055] The portable manual surgical robot of the present embodiment changes the joint position and the joint fixing structure on the basis of the second embodiment.

[0056] like Image 6 As shown, the joint 15 is movable rearward, and the joint is located above the manipulator's wrist joint, and corresponds to the longitudinal position of the manipulator wrist, so that the wrist joint movement is more stable and the distal can be more stable and can eliminate the first example. And the wrist joint caused by the joint 15 in the second secondary structure is curved up and down, and the shake of the shaft and the cutter head 11 improves stability and precision.

[0057] The joint lock drive shaft 17 is shortened so that the force of the joint lock ring 18 is driven to lock the joint lock ring 18 to lock the joint of the joint, and the structure is simpler.

Abstract

The portable manual surgical robot comprises a tool bit, a rod body and a handle, wherein the tool bit is connected to the front end of the rod body through a bent joint, the front end of the joint is fixedly connected with the rod body, and the rear end of the joint is rotationally connected with the handle through a spherical surface; a joint locking switch, which is arranged on the side face of the upper section of the handle, wherein the joint locking transmission shaft and the joint locking ring are located in the joint, one end of the tool bit joint four-direction bending traction steel rope is fixedly connected to the joint locking ring behind the joint bending control shaft, and the other end of the tool bit joint four-direction bending traction steel rope is connected with the tool bit; and a tool bit opening and closing control rod, a tool bit opening and closing traction shaft and a tool bit opening and closing traction steel rope, which are sequentially connected, wherein the front end of the tool bit opening and closing traction steel rope is fixedly connected to the tool bit, the tool bit opening and closing traction shaft rotating fulcrum is arranged in the handle, and the tool bit opening and closing traction shaft is rotationally connected with the tool bit opening and closing traction shaft rotating fulcrum. Extra motor power and computer program assistance are not needed, so that the size and the use cost are reduced, and the portability and the universality are improved.

Description

Technical field [0001] The present invention relates to a portable manual surgical robot, belonging to the field of medical devices. Background technique [0002] Surgery has gradually become current mainstream surgical procedures, which can be inserted into small light sources, cameras and surgical instruments by slits 5-10 mm size. By transferring an image transmitted to the monitor, the operation of the surgical instrument is directed. This surgical surgery is implemented in the abdominal cavity, called laparoscopic surgery, and is called a thoracoscopic surgery when implemented in the chest. [0003] The current cavoscope surgical instrument is straight, the distal end cannot be bent, so the multi-angle to reach the target organization is not possible. Although Da Vinci surgical robots achieve flexible and bending functions through complex mechanical structures, power systems, and computer programs, the expensive price and huge equipment volume cannot be popularized and comme...
