specific Embodiment approach 1

[0008] Specific implementation mode one: as Figure 1~4 As shown, the manipulating device of a radiofrequency electrode ablation catheter handle according to this embodiment includes a base bracket assembly 1, a first driving motor 5, a second driving motor 6, a transmission gear 7, a first motor gear 8 and a second The motor gear 9, the manipulating device also includes a catheter handle clamping part 2, a ball screw nut mechanism 3 and a differential planetary gear train mechanism 4; one end surface of the catheter handle clamping part 2 is provided with a groove along the length direction 2-1, the groove 2-1 is used to install the catheter handle, and a rectangular through hole 2-2 is opened on the side wall of the catheter handle clamping part 2 opposite to the opening of the groove 2-1, and the catheter handle One end of the clamping part 2 is in the shape of a shaft, and the end face of the other end of the catheter handle clamping part 2 is provided with a blind hole 2-...

specific Embodiment approach 2

[0013] Specific implementation mode two: as figure 1 As shown, the base bracket assembly 1 in this embodiment consists of a base plate 1-1, a first column 1-2, a second column 1-3, a first drive motor seat 1-4 and a second drive motor seat 1-5 The first driving motor seat 1-4 and the second driving motor seat 1-5 are both L-shaped, and the first column 1-2 and the second column 1-3 are respectively fixed on both sides of the upper end surface of the bottom plate 1-1. , the first drive motor seat 1-4 and the second drive motor seat 1-5 are fixedly connected to the upper end surface of the base plate 1-1. With such an arrangement, the structure is simple, and the manipulation of the catheter handle is facilitated. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0014] Specific implementation mode three: as figure 1 As shown, the manipulation device in this embodiment also includes a second screw support 3-5, one end of the screw 3-1 is mounted on the second screw support 3-5 through a rolling bearing, and the second screw support 3 -5 is fixed on the outer wall of the catheter handle clamping part 2. Such setting makes the ball screw nut mechanism 3 run more smoothly. Other compositions and connections are the same as those in Embodiment 1 or 2.

[0015] work process (see Figure 1~4 ):

[0016] The invention can automatically control the bending deflection of the distal end of the catheter and the rotation of the handle along the axis:

[0017] If it is necessary to realize the bending of the catheter head, the first drive motor 5 drives the outer sun gear 4-1 in the differential planetary gear mechanism 4 to rotate through the first motor gear 8, and the second drive motor 6 passes through the second motor gear 9 And the trans...

Abstract

The invention provides an operation device of a radio frequency electrode ablation catheter handle, which relates to an operation device of a catheter handle. The invention solves the problems that in the catheter intervene type operation, the intervene process of the radio frequency electrode ablation catheter needs the manual operation of a doctor, so the operation difficulty is great, the precision is not easy to control, and the doctor can not avoid the radiation. An outer sun wheel is arranged on an inner sun wheel shaft through an outer sun wheel connecting disc, a planetary wheel is arranged between the outer sun wheel and an inner sun wheel, outer teeth of the planetary wheel are respectively engaged with inner teeth of the outer sun wheel and outer teeth of the inner sun wheel, a ball nut is arranged on a lead screw, the other end of the planetary wheel shaft is connected with one end of the lead screw through a sleeve barrel shaft coupler, and a slide button clamping and grasping element of the catheter handle is fixed on the ball nut. The invention controls the rotation of the radio frequency electrode ablation catheter handle and the slide of the slide button on the handle through a differential planetary wheel system mechanism, the deflection rotation of the far end of the catheter connected with the handle is further realized, the operation and the control are accurate and convenient, and in addition, the operation is easy.

Description

technical field [0001] The invention relates to a control device for a catheter handle, in particular to a control device for controlling a radio frequency electrode ablation catheter handle in an intracardiac intervention operation. Background technique [0002] The shape of the distal end of the radiofrequency ablation electrode catheter can be changed, which greatly improves the maneuverability of the catheter. It is a common tool in cardiac interventional surgery and is used for cardiac examination and cardiac disease treatment. This type of interventional surgery has been widely used all over the world due to its advantages of less trauma, safety and reliability, and quick postoperative recovery. However, at present, the intervention process of the catheter is still manually operated by the doctor on site, which mainly has the following two disadvantages: 1. The operation is difficult and the accuracy is not easy to grasp. 2. Although the doctor wears a lead suit to pe...
