Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a balloon device capable of measuring coronary pre-expansion. Background Art

[0002] Balloon dilatation catheter is a medical interventional device whose main function is to dilate and treat upper gastrointestinal tract stenosis.

[0003] During use of the existing coronary artery neck balloon dilatation catheter, it is necessary to inject contrast agent into the balloon to measure the length of the coronary artery lesion. However, the existing pre-dilatation balloon will have two black marks under X-ray fluoroscopy, but the specifications of the existing balloons are generally 10mm, 15mm, and 20mm. However, some coronary artery lesions are relatively long, so the length cannot be measured well using such balloons. Only a short balloon can be used to roughly measure and predict the length of the stent to be used, resulting in inaccurate measurement results. Based on the deficiencies in the existing technology, the utility model designs a measurable coronary artery pre-dilatation balloon device. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a measurable coronary artery pre-dilation balloon device, which has the advantage of being easy to measure lesions.

[0005] The utility model provides the following technical solution: a balloon device capable of measuring coronary pre-dilation, comprising a balloon body, the length of the balloon body being 35 mm, a plurality of black marks being arranged on the outer surface of the balloon body, a distance between each two of the black marks being 5 mm, a first through groove being opened on one side of the outer surface of the balloon body, and a second through groove being opened on the other side of the outer surface of the balloon body.

[0006] As a preferred technical solution of the utility model, a first sealing ring is installed on the outer surface of the first through groove, and a guide wire structure is arranged inside the first through groove.

[0007] As a preferred technical solution of the utility model, the guide wire structure includes a guide wire body, and an infusion channel is arranged inside the guide wire body.

[0008] As a preferred technical solution of the utility model, pulling grooves are arranged on both sides of the inner wall of the guide wire body, and pulling wires are passed through the two pulling grooves.

[0009] As a preferred technical solution of the utility model, a second sealing ring is installed on the outer surface of the second through groove, and a steering structure is arranged inside the second through groove.

[0010] As a preferred technical solution of the utility model, the steering structure includes a head, a clamping portion is provided at the bottom of the head, and the clamping portion is sealed and connected to the second through groove.

[0011] As a preferred technical solution of the utility model, a connecting tube is installed on one side of the outer surface of the clamping part, a cross tube is installed at one end of the connecting tube, fixing rings are installed at both ends of the cross tube, springs are installed inside the two fixing rings, and the two springs are fixedly connected to the two pulling wires.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. A coronary pre-dilation balloon device capable of measuring coronary artery pre-dilation has black marks, and the distance between each black mark is 5 mm. When the balloon body is expanded in the blood vessel, the length of the lesion can be measured by observing how many black marks the lesion contains, so that the corresponding stent length can be selected, thereby achieving the purpose of facilitating the measurement of the lesion, improving the accuracy of the measurement, and also improving the practicality of the device;

[0014] 2. This kind of measurable coronary pre-dilation balloon device, through the guide wire structure and the steering structure, when the balloon body is not expanded and moves inside the blood vessel, since the diameter of the head is smaller than the blood vessel, it is inconvenient to turn the device as a whole by only pushing the guide wire body at the bend of the blood vessel. At this time, through the connection between the pulling wire and the spring, when the head needs to be turned to the left, the left pulling wire is pulled. At this time, the spring drives the fixed ring to pull the head to bend to the left. Similarly, turning right can be done by pulling the right pulling wire. When stopping pulling, release the pulling wire, and the spring releases the force to reset the head, thereby achieving the purpose of facilitating steering. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 A balloon device capable of measuring coronary pre-dilation includes a balloon body 1, characterized in that: the length of the balloon body 1 is 35 mm, a plurality of black marks 6 are arranged on the outer surface of the balloon body 1, the distance between each two black marks 6 is 5 mm, a first through groove 2 is opened on one side of the outer surface of the balloon body 1, and a second through groove 4 is opened on the other side of the outer surface of the balloon body 1.

[0023] See also Figure 5 The outer surface of the first through groove 2 is provided with a first sealing ring 3, and the interior of the first through groove 2 is provided with a guide wire structure 7. The guide wire structure 7 includes a guide wire body 71, and the interior of the guide wire body 71 is provided with an infusion channel 72. Pulling grooves 73 are provided on both sides of the inner wall of the guide wire body 71, and the interiors of the two pulling grooves 73 are penetrated with pulling wires 74.

[0024] The contrast agent can be injected into the balloon body 1 through the infusion channel 72 to expand it and open the blood vessel.

[0025] See also Figure 1-4 The second sealing ring 5 is installed on the outer surface of the second through groove 4, and a steering structure 8 is arranged inside the second through groove 4. The steering structure 8 includes a head 81, and a clamping portion 82 is arranged at the bottom of the head 81. The clamping portion 82 is sealed and connected to the second through groove 4. A connecting pipe 83 is installed on one side of the outer surface of the clamping portion 82, and a transverse pipe 84 is installed at one end of the connecting pipe 83. Fixed rings 85 are installed at both ends of the transverse pipe 84. Springs 86 are installed inside the two fixing rings 85, and the two springs 86 are fixedly connected to the two pulling wires 74.

[0026] When the balloon body 1 is not inflated and moves inside the blood vessel, since the diameter of the head 81 is smaller than the blood vessel, it is inconvenient to turn the entire device by only pushing the guide wire body 71 at the bend of the blood vessel. At this time, through the connection between the pulling wire 74 and the spring 86, when the head 81 needs to be turned left, the left pulling wire 74 is pulled. At this time, the spring 86 drives the fixing ring 85 to pull the head 81 to bend to the left. Similarly, when turning right, just pull the right pulling wire 74. When stopping pulling, release the pulling wire 74, and the spring 86 can release the force to reset the head 81.

[0027] Working principle, when a measurable coronary pre-dilation balloon device is used, in the initial state, first, the balloon body 1 is sent into the patient's blood vessel through the guide wire body 71. At this time, since the diameter of the head 81 is smaller than the blood vessel, it is inconvenient to turn the device as a whole by only pushing the guide wire body 71 at the bend of the blood vessel. At this time, through the connection between the pulling wire 74 and the spring 86, when it is necessary to turn the head 81 to the left, the left pulling wire 74 is pulled. At this time, the spring 86 drives the fixing ring 85 to pull the head 81 to bend to the left. Similarly, when turning right, just pull the right pulling wire 74. When the pulling stops, release the pulling wire 74, and the spring 86 releases the force to reset the head 81. When the balloon body 1 reaches the lesion, the contrast agent can be injected into the balloon body 1 through the infusion channel 72 to expand it and open the blood vessel. At this time, the doctor observes the number of black marks 6 contained in the patient's vascular lesion through the picture taken by the X-ray machine, thereby determining the length of the lesion and selecting the corresponding stent.
