Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a guidewire guiding device in percutaneous pulmonary artery balloon angioplasty. Background Art
[0002] Guidewire-guided therapy devices are mainly used for the frequent occurrence of cardiovascular and cerebrovascular diseases. Interventional treatments, such as vascular stents, are becoming more and more common. Among them, more and more guidewires are used to guide and control the corresponding components in various interventional treatments. In the daily treatment of percutaneous pulmonary balloon angioplasty, a guide device is also needed to assist in the use of guidewires.
[0003] In the prior art, there is a guidewire guiding device and a guidewire guiding assembly with a publication number of CN105617512B, wherein the device comprises a guide body (1), wherein a main body guidewire channel (2) and a guidewire guiding channel (3) are respectively provided in the guide body (1), wherein the main body guidewire channel (2) and the guidewire guiding channel (3) respectively penetrate the guide body (1) in the axial direction, and the internal end opening of the guidewire guiding channel (3) and the internal end opening of the main body guidewire channel (2) are spaced apart in the axial direction. The guide body can be inserted into a blood vessel in the body by a main body guidewire passing through the main body guidewire channel, and since the main body guidewire is spaced apart from the internal end opening of the guidewire guiding channel in the axial direction, the guidewire to be guided can enter the guidewire guiding channel in a staggered manner with the main body guidewire in the axial direction, thereby avoiding the problem of mutual entanglement between various guidewires such as the main body guidewire and the branch guidewire.
[0004] However, although the existing guidewire guiding device can guide the guidewire well when in use, it is not very effective in timely fixing the guidewire in the extended state when guiding the guidewire, so that when the guidewire introduction direction and state need to be adjusted, the guidewire will automatically become loose, affecting the medical staff's ability to maintain the guidewire state and the effect of the medical staff on the patient's treatment. At the same time, when the guidewire is introduced, the position alignment accuracy between the threading holes is not high, resulting in position offset between the threading holes, reducing the accuracy of the guidewire insertion hole, reducing the work efficiency of the medical staff when introducing the guidewire, and not meeting people's use needs. For this reason, we propose a guidewire guiding device for percutaneous pulmonary artery balloon angioplasty. Summary of the Invention
[0005] In order to solve the problems mentioned in the above background, the present invention provides a guidewire guiding device in percutaneous pulmonary balloon angioplasty to solve the problem raised in the above background technology that when the guidewire is guided and used, the timely fixation effect of the guidewire in the extended state is not high, so that when the introduction direction and state of the guidewire need to be adjusted, the guidewire will automatically loosen, affecting the medical staff's ability to maintain the guidewire state, and the position alignment accuracy between the threading holes is not high, so that there is a position offset between the threading holes, which reduces the accuracy of the guidewire entering the jack and reduces the work efficiency of the medical staff when introducing and using the guidewire.

When the mounting block 2 is engaged with the connector 1, the block 24 is in contact with the wedge block 25, and under the action of the inclined surface of the extrusion part of the block 24 and the wedge block 25, the telescopic rod 26 and the spring 27 are squeezed until the block 24 and the wedge block 25 are engaged and fixed, and under the reaction of the extrusion of the spring 27, the wedge block 25 is engaged and fixed to the block 24, and the first threading hole 22 and the second threading hole 23 are accurately aligned, thereby improving the accuracy of the subsequent guide wire extending into the connector 1 and improving the work efficiency of the staff in introducing the guide wire.
[0042] like Figure 8 As shown, the central axis of the first threading hole 22 and the central axis of the second threading hole 23 are arranged to overlap with each other, and the inner wall contours of the first threading hole 22 and the second threading hole 23 are both larger than the outer wall contour of the guide wire body 3, which is conducive to improving the accuracy of the guide wire entering the connector 1 through the arrangement of the central axis of the first threading hole 22 and the central axis of the second threading hole 23 overlapping with each other, and is conducive to the arrangement of the inner wall contours of the first threading hole 22 and the second threading hole 23 being larger than the outer wall contour of the guide wire body 3, which facilitates the insertion of the guide wire into the connector 1.

At the same time, the clamping rod 16 is driven to slide along the inner wall of the lifting groove 19, so that the clamping rod 16 is inserted into the inner wall of the clamping groove 20, so that the mounting block 2 and the connector 1 are clamped and fixed, which serves to improve the convenience of assembly and use of the guide wire guiding device.
[0047] Finally, when the mounting block 2 and the connector 1 are installed and used, in order to improve the accuracy of the guide wire inserted into the interior of the connector 1 and improve the efficiency of the medical staff in introducing the guide wire, when the mounting block 2 and the connector 1 are engaged and connected, the block 24 is in contact with the wedge block 25, and under the action of the inclined surface of the extruded part of the block 24 and the wedge block 25, the telescopic rod 26 and the spring 27 are squeezed until the block 24 and the wedge block 25 are engaged and fixed, and under the reaction of the extrusion of the spring 27, the wedge block 25 is engaged and fixed to the block 24, and the first threading hole 22 and the second threading hole 23 are accurately aligned, thereby improving the accuracy of the subsequent guide wire inserted into the connector 1 and improving the work efficiency of the staff in introducing the guide wire.
