[0002] Balloon angioplasty is very common in interventional surgeries such as cardiovascular, peripheral vascular, and cerebrovascular surgeries. In clinical surgeries, balloon expansion and adhesion to the blood vessel wall will block blood flow. Long-term blockage of blood flow will cause tissue failure and necrosis due to ischemia and hypoxia, and cause ventricular fibrillation and myocardial necrosis in cardiovascular surgery, which can threaten the patient's life in severe cases. However, in actual clinical surgeries, repeated expansion is required for the treatment location of the lesion. For example, in drug balloon treatment, extending the expansion and adhesion time will help the drug on the balloon surface to fully act on the lesion.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0027] Example 1

[0028] like Figure 1-2 As shown, this embodiment proposes a catheter seat for a PTA balloon dilatation catheter, including a connector 1, one end of the connector 1 is fixedly connected to a connecting tube 2, the outer end of the connecting tube 2 is fixedly connected to a connecting thin tube 3, one end of the connecting thin tube 3 is fixedly connected to a balloon 4, the outer end of the balloon 4 is fixedly connected to a terminal 5, a shell 6 is provided on the outside of the terminal 5, a circular plate 7 is slidably connected to the inside of the shell 6, a fixing plate 8 is fixedly connected to the bottom of the shell 6, an adapter block 9 is fixedly connected to the bottom of the fixing plate 8, a clamping plate 10 is provided at the bottom of the connector 1, and a connecting groove is provided inside the clamping plate 10.

[0029] In this embodiment, the outer surface of the terminal 5 contacts the inside of the shell 6, and one end of the terminal 5 contacts one side of the circular plate 7, which can facilitate the separation of the circular plate 7 and the terminal 5 and the sliding of the terminal 5.

[0030] In this embodiment, the adapter block 9 extends to the inside of the connection groove, and the outer surface of the adapter block 9 contacts the inside of the connection groove, which can facilitate the connection of the adapter block 9.

[0031] In this embodiment, a support plate 11 is fixedly connected to one side of the outer portion of the clamping plate 10 , and the top of the support plate 11 is in contact with the bottom of the connecting member 1 , so that the support plate 11 can support the connecting member 1 .

[0032] In this embodiment, both sides of the interior of the card plate 10 are provided with card slots 12 , and the two card slots 12 are symmetrically distributed.

[0033] During use, when the terminal 5 needs to be placed, the staff first needs to move the connecting piece 1. During the movement, the connecting piece 1 will synchronously drive the connecting tube 2 and the connecting capillary 3 to move. After the movement, the connecting capillary 3 will synchronously drive the balloon 4 and the terminal 5 to move. Then the staff inserts the terminal 5 into the shell 6. At this time, the terminal 5 is placed. When the terminal 5 is taken out from the shell 6 and the shell 6 needs to be cleaned of mucus, the staff lifts the shell 6 upward. During the lifting process, the shell 6 will synchronously drive the fixing plate 8 and the adapter block 9 to move. After moving, the adapter block 9 will leave the inside of the card plate 10. At this time, the fixing plate 8 is in an unlocked state. Then the staff tilts the shell 6. During the tilting process, the shell 6 will cause the circular plate 7 to slide. When the circular plate 7 slides, the mucus adhered to the inside of the shell 6 can be cleaned. When the cleaning is completed, the staff resets the fixing plate 8 and inserts the adapter block 9 into the connecting groove.

[0034] Example 2

[0035] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the two clamping grooves 12 are fixedly connected with connecting blocks 13 inside, and the tops of the two connecting blocks 13 are fixedly connected with connecting plates 14, which can facilitate the fixation of the connecting blocks 13.

[0036] In this embodiment, springs 15 are fixedly connected to the inner sides of the two connecting plates 14 , and slide plates 16 are fixedly connected to the inner ends of the two springs 15 , which can facilitate the movement of the slide plates 16 .

[0037] In this embodiment, the bottoms of the two slides 16 are in contact with both sides of the top of the card plate 10 respectively, and the tops of the two slides 16 are fixedly connected with adapter plates 17, which can facilitate the slides 16 to drive the adapter plates 17 to move.

[0038] In this embodiment, the two adapter plates 17 are both semicircular in shape, and the insides of the two adapter plates 17 are in contact with the outside of the connecting pipe 2, which can facilitate the connection work of the adapter plates 17.

[0039] In this embodiment, guide plates 18 are fixedly connected to the tops of the two adapter plates 17 , and the two guide plates 18 are arranged to be inclined, so that the guide plates 18 can guide the connecting pipe 2 .

[0040] During use, when it is necessary to support the connecting piece 1 as a whole, the staff will place the connecting piece 1 on the top of the support plate 11, and the support plate 11 will support the connecting piece 1. During this process, the connecting pipe 2 will contact the guide plate 18 and squeeze the guide plate 18 to move. The guide plate 18 will synchronously drive the adapter plate 17 to move during the movement, and the adapter plate 17 will synchronously drive the slide plate 16 to move during the movement. The slide plate 16 will synchronously drive the spring 15 to be compressed during the movement, and then the connecting pipe 2 will slide in between the two adapter plates 17 and be clamped, thereby achieving the support and limiting work of the connecting piece 1. When it is necessary to take out the connecting piece 1, just lift the connecting piece 1 upwards, and the connecting piece 1 will synchronously drive the connecting pipe 2 to slide out of the two adapter plates 17 during the movement, thereby achieving the removal and separation of the connecting piece 1.
