Special catheter device with guide adjusting and pressure maintaining functions for balloon compression

Abstract

The invention relates to the field of medical equipment, in particular to a special catheter device with guide adjusting and pressure maintaining functions for balloon compression. The special catheter device comprises a puncture passage tube, a handle sleeve, a supporting round rod, a compression plate, a push-pull bar I, a supporting bar, a push-pull bar II, a puncture sheet, a guide shell, a pressure block, a threaded column, a balloon catheter, a microballoon, a secondary joint I, a pressure-maintaining and pressure-relieving valve structure, a drawing wire I, a drawing wire II and a secondary joint II. According to the device, the puncture angle is adjusted through the puncture sheet, and thus, the effect of real-time adjustment of the puncture direction and puncture angle can be achieved; the drawing wire section extending out of the outer wall of the catheter is inserted into the balloon catheter section in the microballoon zone, and the function of slight directional bending is exerted on the balloon catheter at the position of the microballoon by tensioning the drawing wires, so that the position of the microballoon can be slightly adjusted during being inflated. Meanwhile, the pressure-maintaining and pressure-relieving valve structure is employed to perform pressure-maintaining and pressure-relieving operations in the injection of the microballoon, thus the stability of the device during use is greatly improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a special catheter device for balloon compression with functions of guide adjustment and pressure maintenance. Background technique [0002] Trigeminal neuralgia is the most common cranial nerve disease. It is mainly manifested by recurrent paroxysmal severe pain in the distribution area of ​​the trigeminal nerve on one side of the face. The incidence rate in domestic statistics is 52.2 / 100,000, with slightly more women than men. Rates can increase with age. Trigeminal neuralgia mostly occurs in middle-aged and elderly people, and the right side is more common than the left side. The characteristics of the disease are: in the distribution area of ​​the trigeminal nerve in the head and face, the onset of sudden onset, sudden arrest, lightning-like, knife-like, burning-like, intractable, unbearable severe pain. Talking, washing your face, brushing your teeth, or a breeze, or ev...

AI Technical Summary

Problems solved by technology

[0004] 1. The puncture operation of the puncture tube in the existing trigeminal nerve puncture operation is a one-time operation. When the puncture direction is not good, the direction cannot be adjusted in real time. It is necessary to pull out the puncture tube and re-puncture until the puncture direction reaches the correct position. This existing method is fault-tolerant The rate is low, and the operation is extremely cumbersome. Almost every successful puncture requires repeated failures to complete the puncture operation, which is very inefficient.

[0005] 2. In the existing operation, the direction and position of the balloon catheter cannot be slightly adjusted according to the actual situation when it is inflated and expanded, which affects the compression and expansion effect of the microballoon to a certain extent

[0006] 3. There is no pressure adjustment device or pressure feedback device when the contrast agent is injected into the microballoon for dilation or compression. Balloon rupture or pressure injury to the associated anatomy

[0007] 4. There is no drug injection port at the front end of the existing balloon catheter, and drug injection operations cannot be performed in combination
