Constant-pressure trigeminal nerve meniscus compression balloon (with additional balloon constant pressure)

Abstract

The invention discloses a constant-pressure trigeminal nerve meniscus compression balloon, which comprises a compression balloon catheter assembly; the compression balloon catheter assembly comprisesan expansion balloon and a supporting tube, and the expansion balloon is located at the end of the supporting tube; the far end of the support tube is connected with an additional balloon positioned in vitro, and the additional balloon is connected with an input source of a contrast agent. The device has the advantages that the additional balloon can buffer the injection pressure of the contrast developer in vitro, so that when the pressure in the expansion balloon changes, the pressure can be transmitted to the additional balloon outside the body; therefore, an operator can observe the pressure conveniently; meanwhile, the operator is reminded of possible surgical abnormal conditions.

Description

Technical field: [0001] The invention relates to a constant-pressure trigeminal nerve semilunar compression balloon. Background technique: [0002] The trigeminal nerve is a mixed nerve. It is the fifth pair of cranial nerves and the largest nerve in the face. It contains two fibers of general somatosensory and special visceral motor. It controls the sensation of the face, mouth, and nasal cavity and the movement of the masticatory muscles, and transmits sensory information from the head to the brain. The trigeminal nerve is formed by the confluence of the ophthalmic branch (first branch), maxillary branch (second branch) and mandibular branch (third branch). The muscles of mastication contract. [0003] The motor part of the trigeminal nerve exits the brain from the junction of the pons and the pontine wall, and then merges into the mandibular nerve, which together exit the cranium through the foramen ovale. The sensory part of the trigeminal nerve is located at the trig...

Problems solved by technology

[0012] 1. In the area covered by the expansion balloon, there is no tube body in some areas. In the area without tube body, when the spring is stretched, the contrast agent enters the expansion balloon from the gap, that is, in the balloon The front end of the front end only relies on the spring and the traction wire to support the balloon, and the spring and the traction wire are connected together by solder joints. Once the solder joint fails, the connection between the spring and the traction wire will fail, which will cause the balloon to fail to inflate, or the spring Detached from the pulling wire, poor reliability

[0013] 2. The rigidity of the front end of the balloon is low, and the catheter assembly is prone to breakage and failure

[0014] 3. After the catheter assembly breaks, it is easy to puncture the balloon. If the balloon breaks, it is easy for the broken and failed parts to fall into the human body, which poses a safety hazard

[0015] 4. In this compression device, the discharge of gas in the tube cannot be realized while the contrast agent is input, because there is air and contrast agent in the expansion balloon at the same time, and the air cannot be developed, resulting in the appearance of the balloon under X-ray and the actual shape. The filling shape of the balloon is deviated, resulting in the loss of visualization and making it difficult to judge the effectiveness and authenticity of balloon filling

[0016] 5. The pillow of the puncture needle is a sharp pillow, which is easy to cut or scratch the surrounding tissue during the puncture, which may easily cause blood vessel and nerve damage
