Embodiment approach 1

[0036] like Figure 1 to Figure 3 As shown, the present invention provides a Y-valve locking device for adjusting the locking force of the Y-valve, the Y-valve is a rotary Y-type connection valve, the Y-valve has a locking knob at its interface, and the Y-valve locks The tightening device comprises a rotary drive mechanism 1, the rotary drive mechanism 1 comprises a motor 11 and a reduction gear set 12, the motor 11 is connected with the input end of the reduction gear set 12, and the output end of the reduction gear set 12 is detachably connected with the locking knob 101, The motor 11 drives the locking knob 101 to rotate forward or reversely by a preset angle through the reduction gear set 12 , so as to control the locking force of the Y valve 100 .

[0037] The invention can realize the continuous stepless adjustment of the rotation angle of the locking knob, so as to realize the continuous adjustment and control of the locking force of the locking knob, so that the lockin...

Embodiment approach 2

[0053] like Figure 1 to Figure 3 As shown, the present invention also provides a guide device, which includes a Y valve 100 and a Y valve locking device, the Y valve 100 is a rotary Y-type connection valve, and the Y valve locking device in this embodiment is the same as the one in the first embodiment. The structure, working principle and beneficial effects are the same, and will not be repeated here.

[0054] like figure 1 , figure 2 , Figure 4 As shown, further, the reduction gear set 12 includes a driving bevel gear 121 and a driven bevel gear 122 that mesh with each other. ) is the same, the motor 11 and the driving bevel gear 121 are located in the lateral direction of the Y valve 100, and the axial direction of the motor 11 and the driving bevel gear 121 is perpendicular to the axial direction of the Y valve 100, and the structure is compact.

Abstract

The invention provides a Y valve locking device and a guiding device, which include a rotary drive mechanism, the rotary drive mechanism includes a motor and a reduction gear set, the motor is connected to the input end of the reduction gear set, and the output end of the reduction gear set is connected to the locking device. The knob is detachably connected, and the motor drives the locking knob to rotate forward or reverse to a preset angle through a reduction gear set. The Y valve locking device of the present invention can realize the continuous stepless adjustment of the rotation angle of the locking knob, so as to realize the continuous adjustment and control of the locking force of the locking knob, so that the locking force can meet the surgical requirements, and neither will The blood overflows due to too small locking force, and the resistance of the guide wire or catheter with balloon / stent to the lesion will not be too large due to too large locking force. Of course, the locking knob can be completely loosened. open or fully locked. The locking device of the present invention has a simple structure, is convenient to use, and is convenient to replace the Y valve.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a Y valve locking device and a guiding device. Background technique [0002] Y valve (ie Y-type connecting valve) is a commonly used interventional medical device, which is used with guide wire or catheter in clinical operations. When using, the front and rear interfaces of the Y valve need to be locked to prevent blood from overflowing. If the locking force is too large, the resistance of the guide wire or the catheter with the balloon / stent to the lesion will be too large, which cannot meet the surgical requirements. At present, the locking force of the Y valve is difficult to control. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a Y valve locking device and a guiding device to solve the problem that the locking force of the Y valve is difficult to control. [0004] In order to achieve the above object, the present invention pr...
