Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a neurosurgery shunt device. Background Art

[0002] As is known to all, neurosurgery is the department that treats diseases of the nervous system, including diseases of the brain and diseases of the spine and spinal cord. Brain diseases include various craniocerebral traumas, cerebrovascular diseases (including cerebral hemorrhage, arteriovenous malformations, aneurysms), various brain tumors, congenital developmental diseases (syringomyelia, atlanto-occipital malformations), intracranial infections, and functional diseases, etc.

[0003] When treating hydrocephalus in children, ventriculoperitoneal shunt surgery is usually required. The specific process is to first insert a hollow soft metal catheter from the subcutaneous tissue layer of the patient's head, through the neck and chest cavity to the subcutaneous tissue of the abdomen, and then make a hole in the skull, and then insert the first thin shunt tube into the catheter from the brain, and extend the other end into the part of the ventricle with water accumulation, and then insert the second shunt tube from the abdomen into the hollow soft metal catheter, and meet the shunt tube extended into the ventricle, and connect the two fine shunt tubes with a pump, and finally pull out the thick medium catheter (hollow soft metal catheter), and then make an incision in the abdominal cavity, and extend the shunt tube of the abdominal subcutaneous tissue layer into the abdominal cavity, and discharge the water accumulated in the ventricle into the abdominal cavity through the shunt tube for digestion and absorption.

[0004] After the above-mentioned ventriculoperitoneal shunt surgery, the child is in the process of growth and development. The shunt placed during the surgery cannot be extended according to the child's physical growth. When the child patient reaches a certain age and develops physically, the shunt becomes relatively shorter. At this time, another surgery is required to install a new shunt. Therefore, the shunt cannot be extended as the child grows during use, which brings certain shortcomings to the neurosurgery shunt. Utility Model Content

[0005] In view of the above problems existing in the prior art, one aspect of the present invention is to provide a neurosurgical shunt device to solve the above deficiencies of the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a neurosurgical shunt device, including a hollow soft metal catheter, a connecting pump and a first shunt tube, the connecting pump is arranged in the hollow soft metal catheter; a second shunt tube, which is arranged on the hollow soft metal catheter; at least one folding portion is arranged in the length direction of the second shunt tube; when the folding portion is unfolded, it is used to extend the length of the second shunt tube.

[0007] Preferably, the folding portion is composed of a plurality of corrugated protrusions connected together.

[0008] Preferably, the first shunt pipe is connected to the second shunt pipe via a connecting pump.

[0009] Preferably, the calibers of the first shunt tube and the second shunt tube are both smaller than the hollow soft metal conduit.

[0010] Preferably, the length of the hollow soft metal conduit is slightly shorter than the total length of the first shunt tube and the second shunt tube.

[0011] Preferably, the maximum width of the folded portion is smaller than the caliber of the hollow soft metal conduit.

[0012] In the above technical scheme, a neurosurgical shunt device provided by the utility model has the following beneficial effects: the utility model, through the folding portion provided on the second shunt tube, can adaptively stretch the folding portion on the second shunt tube during the child's physical development, so that the folding portion can be unfolded to extend the second shunt tube, so that the shunt tube can be adaptively adjusted to a certain extent, thereby weakening or even avoiding the problem that the shunt tube becomes relatively shorter after the child patient reaches a certain age and develops physically, and then a new surgery needs to be performed again to install a new shunt tube. Therefore, the shunt tube cannot be extended as the child's body develops during use, which brings certain shortcomings to the neurosurgical shunt tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] See also Figure 1-2The neurosurgical shunt device is used to solve the problem of ventriculoperitoneal shunt surgery. After the operation, the child is in the process of growth and development. The shunt placed during the operation cannot be extended according to the child's physical growth. When the child patient reaches a certain age and develops physically, the shunt becomes relatively shorter. At this time, another operation is required to install a new shunt. Therefore, the shunt cannot be extended as the child's body grows during use, which brings certain problems to the neurosurgical shunt.

[0020] As a further technical solution proposed by the present invention, it includes a hollow soft metal catheter 1, and also includes: a second shunt tube 4, which is arranged on the hollow soft metal catheter 1; at least one folding portion 4.1 is arranged in the length direction of the second shunt tube 4; when the folding portion 4.1 is unfolded, it is used to extend the length of the second shunt tube 4. Specifically, through the folding portion 4.1 arranged on the second shunt tube 4, the folding portion 4.1 on the second shunt tube 4 can be adaptively stretched during the child's physical development, so that the folding portion 4.1 is unfolded to extend the second shunt tube 4, so that the shunt tube can perform a certain adaptive adjustment, weakening or even avoiding the situation that the shunt tube becomes relatively shorter after the child patient reaches a certain age and develops physically, and then a new shunt tube needs to be installed again through surgery. Therefore, the shunt tube cannot be extended with the child's physical development during use, which brings certain shortcomings to the neurosurgery shunt tube.

[0021] The specific number and length of the folding portion 4.1 in this embodiment are set according to the needs of technical personnel in this field. Secondly, the folding portion 4.1 is essentially equivalent to a corrugated folded straw. It should be noted that in the initial state of the folding portion 4.1, it is in a semi-open state, which is convenient for drainage of the shunt pipe and reduces or even avoids blockage.

[0022] In another embodiment of the present invention, the folding portion 4.1 is specifically composed of a plurality of corrugated protrusions connected together. Furthermore, the specific number of the corrugated protrusions and their diameter lengths are set according to the needs of those skilled in the art.

[0023] In another embodiment of the utility model, it also includes a connecting pump 3 and a first shunt tube 2, which is the prior art. The connecting pump 3 is arranged in the hollow soft metal catheter 1, and the first shunt tube 2 is connected with the second shunt tube 4 through the connecting pump 3. The specific operation process is to first insert the hollow soft metal catheter from the subcutaneous tissue layer of the patient's head, through the neck and chest cavity to reach the subcutaneous tissue of the abdomen, and then make a hole in the skull, and then insert the first thin shunt tube into the catheter from the brain, and extend the other end into the part where the ventricle has water accumulation, and then insert the second shunt tube into the hollow soft metal catheter from the abdominal position, and meet with the shunt tube extending into the ventricle upward, and connect the two fine shunt tubes through a pump, and finally pull out the thick medium catheter (hollow soft metal catheter), and then make an incision in the abdominal cavity, extend the shunt tube of the subcutaneous tissue layer of the abdomen into the abdominal cavity, and discharge the water accumulated in the ventricle into the abdominal cavity through the drainage tube (shunt tube) for digestion and absorption.

[0024] In another embodiment of the present invention, the diameters of the first shunt pipe 2 and the second shunt pipe 4 are both smaller than the hollow soft metal conduit 1. Figure 1 As shown in the state, the hollow soft metal conduit 1 is a medium conduit, which is used for connecting the first shunt pipe 2 and the second shunt pipe 4. It is a prior art and will not be described in detail.

[0025] In another embodiment of the utility model, the length of the hollow soft metal catheter 1 is slightly shorter than the total length of the first shunt tube 2 and the second shunt tube 4. After the hollow soft metal catheter 1 (medium catheter) completes the connection between the first shunt tube 2 and the second shunt tube 4, the hollow soft metal catheter 1 is pulled out from the second shunt tube 4 below, and finally the external end of the second shunt tube 4 is inserted into the patient's abdominal cavity.

[0026] In another embodiment of the present invention, the maximum width of the folded portion 4.1 is smaller than the diameter of the hollow soft metal conduit 1. Figure 1 As shown in the state, the caliber of the hollow soft metal conduit 1 is pulled out from the shunt tube, which increases the fluidity.

[0027] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
