Description

Technical Field

[0001] The invention relates to the technical field of ventricular shunt surgery, and in particular to a blocker for a bypass pipeline of an intracranial ventricular temporal horn-frontal horn shunt surgery. Background Art

[0002] Isolated temporal horn syndrome is a common complication after neurosurgery for intraventricular tumors. Water accumulation leads to isolated expansion of the temporal horn, causing disability or even death in patients, and is very difficult to treat. The principle of the current treatment method is to drain the water accumulation in the temporal horn to an absorbable area (such as the abdominal cavity, the prepontine cistern, and the lateral ventricle), including ventriculoperitoneal shunt, endoscopic choroidal fissure ostomy, and diversion. Among them, ventriculoperitoneal shunt drains the cerebrospinal fluid in the temporal horn to the peritoneal cavity for absorption. Its disadvantage is that the pipeline path is long, which breaks the physiological circulation of cerebrospinal fluid. Shunt blockage and infection often occur. Shunt-dependent headache and abdominal complications occur in the long term. Reoperation is required to adjust the shunt, which is expensive and increases the pain of patients. Endoscopic choroidal fissure ostomy drains the cerebrospinal fluid in the temporal horn to the prepontine cistern through the medial choroidal fissure of the temporal horn. It has high technical requirements for the operator, complex anatomical structure, and is prone to complications such as brainstem and vascular damage. There is a certain failure rate and reoperation is required, which is difficult to promote. The bypass procedure is to drain the cerebrospinal fluid in the temporal horn to the frontal horn where the cerebrospinal fluid circulates normally through a connecting tube bypass. Compared with the ventriculoperitoneal shunt, the tube path is short, not easy to be blocked and infected, there are no abdominal complications, the operation time is short, and the cost is low. Compared with endoscopic choroidal fissure fistula, the technology is simple and easy to promote.

[0003] In clinical operation, it is necessary to temporarily block the cerebrospinal fluid drainage through the ventricle. The existing operation method is to use silk thread to ligate the drainage tube, which has the following shortcomings during operation: 1. It is difficult to control the tightness of the wire-ligated drainage tube on the inner side of the scalp. When the wire ligation is loose, leakage is likely to occur. On the one hand, forceful ligation is likely to cause a large floating movement of the frontal angle connecting tube and damage the ventricle end. On the other hand, it is easy to damage the tube wall at the ventricle end, affecting normal use. Summary of the invention

[0004] In view of this, the present invention proposes an occluder for the bypass line of the temporal horn-frontal horn shunt in the intracranial ventricle, so as to prevent excessive ligation from causing damage to the frontal horn single-lumen branch tube of the double-lumen ventricular tube while ensuring the blocking effect.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A blocker for a bypass line of an intracranial ventricular temporal horn-frontal horn shunt operation comprises a blocker body of a cylindrical structure, one end of the blocker body is coaxially fixed with a first joint, and the other end of the blocker body is coaxially fixed with a second joint, the first joint and the second joint are respectively placed in a frontal horn single-lumen branch tube of a double-lumen ventricular tube and tied and fixed, so that the passage of the frontal horn single-lumen branch tube of the double-lumen ventricular tube is blocked.

[0007] To better implement the above technical solution, optionally, the first connector and the second connector both include a binding section and a plug section, the two ends of the binding section are respectively connected to one end of the plug section and one end of the blocker body, the plug section has a conical structure, the large diameter end of the plug section has an interference fit with the inner wall of the single-lumen branch tube of the frontal angle of the double-lumen ventricular tube, the binding section has a cylindrical structure, and the diameter of the binding section is smaller than the inner diameter of the single-lumen branch tube of the frontal angle of the double-lumen ventricular tube.

[0008] Optionally, the end of the plug section facing away from the binding section is a rounded end.

[0009] Optionally, the blocker body, the first connector and the second connector are an integrally formed structure.

[0010] Optionally, the frontal angle single-lumen branch tube of the double-lumen ventricular tube is provided with a sealing convex ring on the inner wall cooperating with the two binding sections.

[0011] Beneficial effects of the present invention:

[0012] The present invention is a kind of blocker for the bypass line of the temporal angle-frontal angle shunt in the intracranial ventricle, which changes the traditional silk thread ligation method outside the tube to the method of blocking inside the tube combined with fixing outside the tube, improves the accuracy and stability of the blockage, effectively prevents cerebrospinal fluid leakage, and provides a solid guarantee for the prognosis of the operation. Moreover, during the whole operation, the tube wall of the double-cavity ventricular tube will not be damaged, and the original structural integrity of the ventricular tube is maintained to the greatest extent. In addition, its operation process is greatly simplified, and medical staff can quickly complete the blocking operation with only a few simple steps, which greatly shortens the operation time and reduces the intraoperative risk of patients.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0018] See also Figure 1 The embodiment of the present invention discloses an occluder 100 for a bypass line of an intracranial ventricular temporal horn-frontal horn shunt operation, comprising an occluder body 110 of a cylindrical structure, a first joint 120 being coaxially fixedly disposed at one end of the occluder body 110, and a second joint 130 being coaxially fixedly disposed at the other end of the occluder body 110, the first joint 120 and the second joint 130 being respectively placed in a frontal horn single-lumen branch tube 210 of a double-lumen ventricular tube and tied and fixed, so that the passage of the frontal horn single-lumen branch tube 210 of the double-lumen ventricular tube is blocked.

[0019] In the embodiments of the present invention, it should be noted that the double-lumen ventricular tube includes a frontal angle single-lumen branch tube 210 and a fluid storage bag / external drainage single-lumen branch tube 220, the proximal ends of which are connected to form an integrated structure, and the distal ends of which are separated from each other, wherein the distal end of the frontal angle single-lumen branch tube 210 is inserted into the frontal angle 305 of the ventricle, and the distal end of the fluid storage bag / external drainage single-lumen branch tube 220 is connected to the fluid storage bag 306 or the external drainage tube, and the blocker 100 is used to block the passage of the frontal angle single-lumen branch tube 210.

[0020] According to an embodiment of the present invention, a blocker 100 for a bypass line of an intracranial ventricular temporal angle-frontal angle shunt surgery is disclosed. A frontal angle single-lumen branch tube 210 is disconnected in the middle to form a first section 211 inserted into the frontal angle 305 of the ventricle and a second section 212 connected to the main body of the double-lumen ventricular tube. A first joint 120 is inserted into the end of the first section 211 away from the frontal angle 305 of the ventricle, and a silk thread is used to wrap and fix the connection between the first section 211 and the first joint 120. A second joint 130 is inserted into the end of the second section 212 away from the main body of the double-lumen ventricular tube, and a silk thread is used to wrap and fix the connection between the second section 212 and the second joint 130. The blocker 100 of the present invention has a circumferential supporting function because the first joint 120 and the second joint 130 have circumferential supporting functions, so that the inner walls of the frontal angle single-lumen branch tube 210 will not fit each other when the silk thread is tied, thereby effectively controlling the tightness of the binding and avoiding the problem of leakage caused by loose binding and damage to the frontal angle single-lumen branch tube 210 caused by tight binding.

[0021] like Figure 1 As shown, in an embodiment of the present invention, the first connector 120 and the second connector 130 both include a binding section 121 and a plug section 122, the two ends of the binding section 121 are respectively connected to one end of the plug section 122 and one end of the blocker body 110, the plug section 122 is a conical structure, the large diameter end of the plug section 122 is interference fit with the inner wall of the frontal angle single lumen branch tube 305 of the double-lumen ventricular tube, the binding section 121 is a cylindrical structure, and the diameter of the binding section 121 is smaller than the inner diameter of the frontal angle single lumen branch tube 305 of the double-lumen ventricular tube, the plug section 122 is inserted into the frontal angle single lumen branch tube 305, which can isolate the frontal angle single lumen branch tube 305, and then use silk thread to tighten and wrap around the outer wall of the frontal angle single lumen branch tube 305 corresponding to the circumference of the binding section 121, thereby increasing the sealing of the connection between the blocker 100 and the frontal angle single lumen branch tube 210.

[0022] like Figure 1 As shown, the end of the plug section 122 away from the binding section 121 is a rounded end, and the blocker body 110, the first connector 120 and the second connector 130 are an integrally formed structure, which is beneficial to improving the stability of the blocker 100.

[0023] In an embodiment of the present invention, the frontal angle single lumen branch tube 210 of the double lumen ventricular tube is provided with a sealing convex ring on the inner wall cooperating with the two binding sections 121. The provision of the sealing convex ring can increase the sealing performance of the connection between the blocker 100 and the frontal angle single lumen branch tube 305.

[0024] like Figure 2 As shown, the embodiment of the present invention discloses a surgical plan for using a breaker 100 for bypassing a temporal angle-frontal angle shunt in an intracranial ventricle:

[0025] 1. The patient had acute isolated enlargement of the temporal horn 304 of the ventricle after surgery, and intracranial infection could not be ruled out. After general anesthesia, the head was fixed with a head frame, and the frontal and temporal horn punctures were completed using a robotic navigation system. The puncture points were the frontal horn puncture point 301 and the Frazier puncture point 302 of the ventricle, respectively. The double-lumen section of the double-lumen ventricular tube was used in the temporal horn area 304.

[0026] 2. The intraoperative rapid cerebrospinal fluid detection system indicates cerebrospinal fluid infection in the temporal horn area. The frontal horn single-lumen branch tube 305 of the double-lumen ventricular tube uses a blocker 100 to temporarily block the flow of cerebrospinal fluid into the frontal horn 305 of the ventricle. The fluid reservoir / external drainage single-lumen branch tube 220 of the double-lumen ventricular tube is connected to the fluid reservoir 306 or the external drainage tube for anti-infection treatment.

[0027] 3. After the infection in the temporal horn 304 of the ventricle is cured, replace the occluder 100 with an open connecting pipe joint (the open connecting pipe joint is patent application number CN2021114781092, patent name A connecting joint in a ventricular bypass bypass system), and remove the fluid storage bag 306 or the external drainage tube connected to the fluid storage bag of the double-lumen ventricular tube / external drainage single-lumen branch tube 220, and replace it with the occluder 100, and place it under the scalp.

[0028] The embodiment of the present invention discloses a blocker 100 for the bypass line of the intracranial ventricular temporal angle-frontal angle shunt, which changes the traditional silk thread tube ligation method to a tube blockage combined with tube fixation, improves the accuracy and stability of the blockage, effectively prevents cerebrospinal fluid leakage, and provides a solid guarantee for the prognosis of the operation. In addition, during the whole operation, the tube wall of the double-lumen ventricular tube will not be damaged, and the original structural integrity of the ventricular tube is maintained to the greatest extent. In addition, its operation process is greatly simplified, and medical staff can quickly complete the blocking operation with only a few simple steps, which greatly shortens the operation time and reduces the intraoperative risk of patients.

[0029] The technical solution of the present invention is described in detail above in conjunction with specific embodiments, and the described specific embodiments are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the protection scope of the present invention.
