Abstract
The utility model relates to a hydrocephalus treatment field, in particular to degradable prevents blockking up ventricle shunt tubes for treatment hydrocephalus. This treatment hydrocephalus is with degradable prevents blockking up ventricle shunt tubes, including the shunt tubes pipe shaft, shunt tubes pipe shaft front end lateral wall is equipped with apopore, characterized by: the front end of the shunt tube body is connected with a degradation end in a split mode, and the degradation end is made of biodegradable materials. The degradable anti-blockage ventricle flow dividing tube for treating hydrocephalus has a simple structure, can effectively reduce the incidence rate of blockage of the flow dividing tube or prolong the blockage period of the flow dividing tube, avoids the risk of cerebral hemorrhage or cerebral injury caused by frequent replacement of the flow dividing tube, is beneficial to treating patients, and has great clinical popularization value.
Description
(1) technical field
The present invention relates to the treatment of hydrocephalus field, particularly a kind of treatment hydrocephalus is with degradable blockage resisting ventricular shunt pipe.
(2) background technology
At present clinically when treating hydrocephalic disease; The complication that often occurs is exactly that isocon stops up, and present processing method can only be pulled out isocon it is changed, and when pulling out and changing isocon, can produce the risk of cerebral hemorrhage or brain injury; And present isocon blockage problem is more serious; Period ratio is shorter, and generally performing the operation promptly had the patient of 40%-50% the plugging problem to occur in back about 1 year, makes the replacing isocon more frequent; Cause the probability of cerebral hemorrhage or brain injury to increase to patient, be unfavorable for patient is treated.
(3) summary of the invention
The present invention provides a kind of treatment hydrocephalus that reduces isocon obstruction incidence rate with degradable blockage resisting ventricular shunt pipe in order to remedy the defective of prior art.
The present invention realizes through following technical scheme:
A kind of treatment hydrocephalus is with degradable blockage resisting ventricular shunt pipe; Comprise the isocon pipe shaft; Isocon pipe shaft front end side wall is provided with apopore, it is characterized in that: the split type degraded termination that is connected with of isocon pipe shaft front end, the material of degraded termination is a Biodegradable material.
This treatment hydrocephalus is with degradable blockage resisting ventricular shunt pipe; Isocon pipe shaft front end side wall is provided with a plurality of hiding apopores; Hide the apopore surfaces coated and be covered with one deck degradable coating; The material of degradable coating is a Biodegradable material, and the degradable coating can also be avoided because apopore too much causes the risk of cerebral hemorrhage or brain injury when intubate.The coating direction of degradable coating is horizontal or vertical.The degraded termination plugs with the isocon pipe shaft or is connected through screw thread.
This treatment hydrocephalus is with degradable blockage resisting ventricular shunt pipe; Through on existing isocon basis, setting up degraded termination and the degradable coating of processing by Biodegradable material; Reached the anticlogging purpose of isocon; The duration of congestion of isocon is prolonged, solved the susceptible to plugging difficult medical problem of present hydrocephalus isocon.The Biodegradable material that is adopted can be selected polylactic acid-based material, polyglycolic acid class material and copolymer thereof etc. for use.Degraded in vivo mainly is that non-enzymatic hydrolysis method with ester bond carries out like polylactic acid; Product is lactic acid (metabolite of sugar) wherein; And lactic acid can get into the tricarboxylic acid cycle of body metabolism; Finally be metabolized to water and carbon dioxide, excrete with various forms through respiratory tract, urine, skin etc.
The invention has the beneficial effects as follows: this treatment hydrocephalus is with degradable blockage resisting ventricular shunt pipe; Simple in structure; Can effectively reduce isocon stops up incidence rate or prolongs the isocon obstruction cycle; Avoid the cerebral hemorrhage that the frequent change isocon causes or the risk of brain injury, be beneficial to patient is treated, had very big clinical generalization value.
(4) description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is treated the structural representation of hydrocephalus with degradable blockage resisting ventricular shunt pipe for the present invention.
Accompanying drawing 2 is the structural representation of degradable coating longitudinal application of the present invention.
Among the figure, 1 isocon pipe shaft, 2 degraded terminations, 3 apopores, 4 hide apopore, 5 degradable coatings.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This treatment hydrocephalus is with degradable blockage resisting ventricular shunt pipe; Comprise isocon pipe shaft 1; Isocon pipe shaft 1 front end side wall is provided with apopore 3, it is characterized in that: the split type degraded termination 2 that is connected with of isocon pipe shaft 1 front end, the material of degraded termination 2 is a Biodegradable material.Isocon pipe shaft 1 front end side wall is provided with a plurality of hiding apopores 4, hides apopore 4 surfaces coated and is covered with one deck degradable coating 5, and the material of degradable coating 5 is a Biodegradable material.The coating direction of degradable coating 5 is horizontal or vertical.Degraded termination 2 plugs with isocon pipe shaft 1 or is connected through screw thread.
This treatment hydrocephalus with degradable blockage resisting ventricular shunt pipe, the common isocon method for using of Guan Shiyu is identical putting, when put manage successfully after; Degraded termination 2 and degradable coating 5 can slowly be degraded in human body and be absorbed; Finally can make isocon pipe shaft 1 be uncovered shape foremost, and the hiding apopore 4 of isocon pipe shaft 1 sidewall is unlimited, and apopore quantity is increased; Can prevent effectively that isocon from stopping up; Prolong isocon and stop up the cycle, reduce isocon and stop up incidence rate, thereby avoided the operation risk that when changing isocon, patient caused.
Claims (4)
1. a treatment hydrocephalus is with degradable blockage resisting ventricular shunt pipe; Comprise isocon pipe shaft (1); Isocon pipe shaft (1) front end side wall is provided with apopore (3); It is characterized in that: the split type degraded termination (2) that is connected with of isocon pipe shaft (1) front end, the material of degraded termination (2) is a Biodegradable material.
