Definitions

  • the purpose of the present invention is to provide an instrument joint used in laparoscopic surgery to replace or complement the usual grip, with advantages in ergonomics, comfort and ease of operation for its end users, laparoscopic surgeons.
  • Laparoscopy is a surgical approach in which it operates through small incisions.
  • the instruments can be of durable material (said permanent) or not (disposable). Are formed
  • a handle holding the operator's hand
  • a thin body through which a rod that transmits, the force of the grip to the tip
  • a tip of various possible types which can be static or open and close according to the movement transmitted by the body.
  • the wrist joint With the fixed handle, the wrist joint is overloaded, as it is often found in the lateral (total abduction), medial (total adduction), anterior (total flexion) and posterior (total extension) extremities of position when moving the wrists. fingers of the surgeon's hand.
  • the movement The set of the instrument not articulated with the surgeon's upper limb is uncomfortable and tiring, because when the instrument is projected in any direction (to perform any surgical maneuver), the handle describes a semicircular movement that alters the angle between the instrument and the abdomen of the patient.
  • the wrist Since the surgeon's fingers (embedded in the handle) must remain in the same position to hold and operate the instrument (open, close, grasp, cut, dissect), the wrist is often forced to articulate to the extremes of position, with concomitant extension of the forearm. Thereafter, if necessary even greater range of motion, the forearm reach maximum extension and shoulder muscles will be activated to lift the entire upper limb and adding more discomfort to the ⁇ process.
  • the joint is formed by: parts that, when fitted, allow rotation movement around its axis.
  • the angle of rotation formed between the body of the instrument and the handle changes dynamically and automatically each time the surgeon moves the instrument from the fixed point on the patient's abdomen.
  • the articulation mechanism is constructed in such a way that the surgeon's motor commands are transmitted from the handle to the tip of the instrument through the articulation, as in the non-articulated instrument, regardless of the angle of rotation at which the articulation is located. There is no need to perform one step at a time, such as opening the forceps, articulating the instrument, and closing the forceps: the entire process occurs simultaneously. Position locks (closed) as well. can be used, and the pivot will rotate in the same way as long as the lock remains engaged.
  • the presence of the joint also does not affect the grip design (straight, curved, with or without rack, pom or without finger rings) when embedded in it, so it can be used in all laparoscopic instruments (tweezers, dissector, scissors, door needle, vacuum cleaner, gripper, hook, etc.).
  • the innovative character of the present invention resides in the idealization of the articulation for embedded or coupled laparoscopic surgery instruments, which will give superior ergonomics and comfort to the operator of the instruments, whether used in any medical or veterinary specialty.
  • the propositions (below) of mechanisms that meet the requirements of such articulation do not limit patent rights solely to these mechanisms, as any form of obtaining the expected result - articulation that transmits the force exerted from one end (grip) to another (when necessary, while allowing rotation about its axis - will achieve the core objective of this patent and is covered by it regardless of the shape, size, design or material employed in its manufacture.
  • the joint is formed by a body and a circular part, which are connected by a circular socket, where the rotation of the joint occurs. Internally, it consists of gears that have two sprockets (proximal and distal) of sprockets, a sprocket that communicates the two sprockets, and two straight sprockets, each attached to one of the shafts and one of the sprockets. free ends, where the handle (proximal end) and the body of the instrument (distal end) will fit. Each wheel axle is formed by two fixedly connected wheels, so that when one rotates, the other must also rotate.
  • axles do not necessarily have the same radius (same number of teeth). However, both axles have two identical wheels of the same radius (hence the same number of teeth), on which runs the seat belt that communicates the axles. These wheels have the same radius to prevent the force transmitted through the mechanism from being interfered with pivot rotation, otherwise rotation could cause the force to decrease or increase depending on the direction in which it occurred.
  • the handle When the handle is actuated by the operator, it moves the proximal end sprocket, which therefore moves the proximal shaft sprocket, also moving (through the shaft) the other wheel, connected to the chain; the movement of the chain rotates the distal axis through the identical wheel, also turning its other wheel, it is moving the distal toothed cable and completing the force transfer cycle to the instrument body. Power transfer occurs in one direction (pushing to open the tip of the instrument) and in another direction (pulling to close the tip of the instrument).
  • the circular part can rotate 360 degrees around the shaft without obstacles.
  • the direction of rotation is not mandatory, it can be clockwise and counterclockwise.
  • the circular piece is not mandatory, it can be clockwise and counterclockwise.
  • the distal wheel axle attaches inwardly to the right on the wall of the articulation body and to the left in the center of the circular part so that both have the same axis of rotation but with independent movements.
  • the proximal wheel axle attaches internally to the pivot body, rotating about a different axis of rotation from the distal wheel axle and the circular part. Toothed cables, in addition to articulating with their respective wheels, articulate with fixed parts on the walls of the joint body and circular part, which keep them attached to them and allow the cables to slide in linear round-trip movements.
  • the proximal wheel axle (within the articulation body) describes translational movement around the distal axis.
  • the proximal axis remains immobile in relation to its axis, with no rotation. Since the wheels where the toothed belt are fitted have the identical radius, the belt is moving, passively accommodating to the new position. Thus, joint rotation can occur regardless of the force transmission.
  • the joint body is the body of the handle itself, and the gears fit into it.
  • the proximal toothed cable therefore does not require a socket, it is already permanently seated in the cable rod that receives movement from the surgeon's hand.
