Description

[0001] Divisional application This application is a divisional application of the Chinese invention patent application [Application Number: 202410620395.9] [Invention Name: A conveniently adjustable ventriculoperitoneal shunt strip] filed on May 17, 2024. Technical Field

[0002] The invention belongs to the field of ventriculoperitoneal shunt instruments, and in particular relates to a conveniently adjustable ventriculoperitoneal shunt strip. Background Art

[0003] Ventriculoperitoneal shunt surgery requires the use of a cleaning rod to first implant the drainage tube into a subcutaneous tunnel. The cleaning rod includes a hard sleeve and a guide core inside the hard sleeve for connecting the drainage tube. After constructing the subcutaneous tunnel through the hard sleeve, the drainage tube is connected to the guide core. While pulling the guide core out of the hard sleeve, the drainage tube is placed into the subcutaneous tunnel for subsequent shunt operations.

[0004] For example, the utility model with publication number CN218739676U discloses a visual ventriculoperitoneal shunt strip, comprising an outer sleeve, the right end of which is connected to a head end adjustment portion, a guide core channel is opened inside the outer sleeve, and a guide core is arranged in the guide core channel, a clip mechanism is arranged at the right end of the guide core, a moving part is arranged at the left end of the guide core, and a fixing mechanism is arranged on the moving part; the fixing mechanism comprises a rotating disk rotatably connected to the right end face of the moving part through a rotating bearing, a connecting rod is rotatably connected to the right end face of the rotating disk and at a position away from the center of the circle through a bearing, a through hole is opened at the left end of the outer sleeve, and the other end of the connecting rod passes through the through hole at the left end of the outer sleeve and is provided with a knob.

[0005] The above scheme fixes the moving mechanism and the outer sleeve through a fixing mechanism, which can effectively prevent the position of the moving part from moving during the creation of the subcutaneous tunnel. The moving part drives the position of the guiding inner core to move, thereby causing the clip mechanism to cause secondary damage to the patient.

[0006] However, in the process of creating a subcutaneous tunnel (i.e. inserting the outer sleeve into the human body), since the outer sleeve has a certain length, the operator applies force through the gripping handle set at the end of the outer sleeve. The force-generating point and the force-receiving point are far apart, making it inconvenient to apply force, especially when the outer sleeve is first inserted into the human body. At this time, the force-generating point and the force-receiving point are separated by the entire length of the outer sleeve, which can easily lead to deviations in the insertion direction of the outer sleeve, thereby causing damage to other parts of the human body. At the same time, since different human bodies are of different heights, the length of the subcutaneous tunnel to be constructed also varies to a certain extent, while the length of the outer sleeve in this solution is fixed and cannot be adjusted, thereby failing to meet the outer sleeve length requirements of different human bodies.

[0007] Therefore, there is an urgent need for a ventriculoperitoneal shunt that is easy to operate and has better stability. Summary of the invention

[0008] The object of the present invention is to provide a conveniently adjustable ventriculoperitoneal shunt strip to partially alleviate or solve the above-mentioned problem, thereby making the process of constructing a subcutaneous tunnel more convenient.

[0009] In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions: A conveniently adjustable ventriculoperitoneal shunt strip comprises a first tube, two second tubes and two locking handles; The two second pipes are movably arranged in the first pipe from both ends of the first pipe, and the outer walls of the first pipe and the second pipe are both provided with scale lines; the outer wall of the first pipe is provided with an external thread, and the inner wall of the locking handle is provided with an internal thread matching the external thread, and the outer walls of both ends of the first pipe are respectively provided with a plurality of inclined parts that can be retracted inward, and the plurality of inclined parts can be moved closer to the second pipe under the action of external force, and the inner wall of the locking handle is provided with an inner inclined surface having the same inclination angle as the outer inclined surface of the inclined part; When the locking handle is screwed into the first pipe, the inner inclined surface moves closely against the outer inclined surface and squeezes the inclined portion, so that the inclined portion is deformed, and the plurality of inclined portions together form a clamping structure for clamping the second pipe; It also includes a clamping member movably arranged on the shunt flow bar, the clamping member includes a connecting portion and a clamping portion that are fixedly connected, one end of the connecting portion is sleeved on the shunt flow bar through a first through hole, the clamping portion is provided with a first groove that matches the shunt flow bar on one side close to the shunt flow bar, the clamping portion is also provided with an elastic portion for resetting the clamping portion, and the elastic portion is sleeved on the shunt flow bar through a second through hole; When the clamping portion is expanded to the maximum, both the first through hole and the second through hole can pass through the locking handle; when the clamping portion is pressed inward, the clamping portion is close to the bypass strip, so that the groove wall of the first groove is clamped on the outer wall of the bypass strip.

[0010] As an improvement, a portion of the inner wall of the first pipe is recessed toward the outer wall to form a recessed portion, and the recessed portion is located between the inclined portion and the external thread.

[0011] As an improvement, the angle between the extension line of the outer slope and the central axis of the first pipe is 5°-20°.

[0012] As an improvement, the length of the inner bevel is greater than the length of the outer bevel, so that when the locking handle is screwed into the first pipe, the inner bevel is always in contact with the outer bevel.

[0013] As an improvement, the outer diameter of the locking handle increases from small to large and then decreases from the first end to the second end.

[0014] As an improvement, a transition zone is provided at the first end of the second pipe, and the outer diameter of the transition zone gradually decreases from the second end to the first end of the second pipe.

[0015] As an improvement, a receiving cavity for installing the elastic part is opened inside the connecting part, the movable end of the elastic part can be movably sleeved on the branch flow strip, and the connecting end of the elastic part is fixedly arranged on the inner wall of the clamping part.

[0016] As an improvement, the front end of the ventriculoperitoneal shunt strip is detachably provided with a bullet-shaped tip.

[0017] As an improvement, an anti-slip protrusion is provided on a side of the clamping portion away from the first groove.

[0018] As an improvement, a gap is left between the elastic portion and the connecting portion to provide deformation space for the elastic portion.

[0019] The principle and beneficial technical effects of the present invention are: In the prior art (patent document with publication number CN218739676U), the gripping handle is arranged at the end of the outer sleeve, and force can only be applied through the gripping handle during use. The force point is far away from the end of the outer sleeve that enters the human body, which makes it inconvenient to apply force. At the same time, it is very likely to affect the insertion accuracy, thereby affecting the treatment effect.

[0020] In the present application, a clamping member is designed to be movable relative to the bypass flow strip. When in use, the position of the clamping member can be adjusted at any time according to the insertion depth of the bypass flow strip, thereby ensuring that the force point is always close to the human body, thereby ensuring the insertion effect. At the same time, the clamping member cooperates with the connecting part, the clamping part and the elastic part. When in use, it is only necessary to press the clamping part so that the groove wall of the first groove fits with the outer wall of the bypass flow strip, thereby achieving relative fixation of the clamping member and the bypass flow strip. When moving the clamping member, it is only necessary to stop pressing, and the elastic part drives the clamping part to reset. The structure is simple and the operation is convenient. At the same time, by setting a segmented design of the pipeline, it is more convenient to adjust the position of the force point during insertion.

[0021] In addition, the first pipe and the second pipe are fixed by the locking handle. When in use, the locking handle only needs to be screwed into the first pipe through the thread. During the screwing-in process of the locking handle, the corresponding part of the inner oblique surface of the locking handle squeezes the inclined part, so that the outer wall of the second pipe and the inner wall of the inclined part fit tightly. The friction between the two makes the two relatively fixed, the fixing effect is better, and the operation is convenient and quick. At the same time, since the locking handle is arranged on the outside of the first pipe and is not in direct contact with the second pipe, the length of the second pipe extending into the first pipe can be adjusted at will, thereby realizing the adjustment of the overall length of the pipe.

[0022] In summary, the present application designs a multi-section detachable pipe, and cooperates with a movable clamping member to make the bypass flow strip structure simple, easy to operate and effective. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Herein, the suffixes such as "module", "component" or "unit" used to represent elements are used only to facilitate the description of the present invention and have no specific meaning in themselves. Therefore, "module", "component" or "unit" can be used in a mixed manner. Herein, the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front", "back", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] In this document, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In this document, "plurality" means two or more, that is, it includes two, three, four, five, etc.

[0029] The embodiment is basically as shown in Figures 1-7c: like Figure 1a and Figure 1bAs shown, the present invention provides a conveniently adjustable ventriculoperitoneal shunt, comprising a first conduit 1, a second conduit 2, and a locking handle 3 for fixing the first conduit 1 and the second conduit 2, wherein the inner diameter of the first conduit 1 is larger than the outer diameter of the second conduit 2, so that the second conduit 2 can slide inside the first conduit 1, thereby achieving adjustment of the overall length of the shunt; specifically, as Figure 2 The outer wall of the first pipe 1 is provided with an external thread 4, and the inner wall of the locking handle 3 is provided with an internal thread 5 matching the external thread 4. The outer wall of the first end of the first pipe 1 shrinks inward to form a plurality of inclined portions 6, wherein the shapes and sizes of the inclined portions 6 are consistent, and there is a certain gap between adjacent inclined portions 6. The inclined portions 6 do not contact the second pipe 2 when no force is applied. When the inclined portions 6 are deformed by force, the inclined portions 6 simultaneously move closer to the second pipe 2, and the gaps between adjacent inclined portions 6 are reduced, and all inclined portions 6 together form a clamping structure for clamping the second pipe 2; the inner wall of the locking handle 3 is provided with an inner inclined surface 8 having the same inclination angle as the outer inclined surface 7 of the inclined portion 6. When the locking handle 3 is screwed into the first pipe 1, the locking handle 3 moves relative to the first pipe 1 along the extension direction of the external thread 4, and the inner inclined surface 8 moves close to the outer inclined surface 7 and squeezes the inclined portion 6, so that the inclined portion 6 clamps the second pipe and the two are relatively fixed.

[0030] When in use, the required length of the shunt strip is determined according to the height of different people and other conditions, and then a portion of the second pipe 2 is inserted into the first pipe 1 so that the overall length of the shunt strip reaches the target length, and finally the two are fixed by locking the handle 3 (such as Figure 3 ).

[0031] Among them, the number of turns of the external thread 4 and the internal thread 5 can be adjusted, and the length of the inner bevel 8 can be adjusted synchronously, so that when the locking handle 3 is in a locked state, the inner bevel 8 can squeeze the outer bevel 7, thereby ensuring that the inner wall of the inclined portion 6 is always in close contact with the outer wall of the second pipe 2 (for example, when the number of turns of the thread is two, the length of the inner bevel 8 can be set shorter, and at this time, only the locking handle 3 needs to be turned two turns to lock it). Of course, under normal circumstances, the more turns of the internal thread 5 and the external thread 4, the longer the length of the outer bevel 7, and the better the locking effect, but the operation is relatively cumbersome.

[0032] In some embodiments, the angle between the extension line of the outer bevel 7 and the central axis of the outer sleeve is 5° to 20° (preferably 10°). In some embodiments, the outer diameter of the first end of the second pipe 2 (i.e., the end inserted into the first pipe 1) gradually decreases from the second end to the first end of the second pipe 2 to form a transition zone 14, so that the second pipe 2 can be easily inserted into the first pipe 1.

[0033] In some embodiments, in order to reduce the resistance encountered when the inclined portion 6 approaches the second pipe 2 and at the same time reduce the twisting resistance of the locking handle 3, the inner wall of a portion of the first pipe 1 is recessed toward the outer wall to form a recessed portion 13, and the recessed portion 13 is located between the inclined portion 6 and the external thread 4.

[0034] In some embodiments, scale lines are provided on the outer walls of the first pipe 1 and the second pipe 2, so as to facilitate the determination of the overall length of the bypass flow strip, thereby making the length adjustment of the bypass flow strip more intuitive.

[0035] It should be noted that in the above scheme, the shunt flow strip is composed of a first tube 1 and a second tube 2. Under normal circumstances, the total length of the first tube 1 and the second tube 2 is sufficient to meet the shunt flow strip length requirement in ventriculoperitoneal shunt surgery; but it can be understood that the number of tubes can be adjusted according to the target length of the shunt flow strip. For example, when the length of the first tube 1 and the second tube 2 is not enough, the same method can be used to pass another second tube 2 at the end of the first tube 1 that is not passed into the second tube 2, and at the same time, it is fixed by the locking handle 3, thereby increasing the overall length of the shunt flow strip.

[0036] like Figure 5 The shunt strip is also provided with a clamping member (similar to the gripping handle 16 in the prior art, such as Figure 6 , which is convenient for the operator to hold the shunt bar when inserting it into the patient's body), the clamping piece includes a connecting part 9, a clamping part 11 and an elastic part 10 for resetting the clamping part 11, wherein one end of the connecting part 9 is provided with a first through hole, and it is sleeved on the shunt bar through the first through hole, and the connecting part 9 is provided with a receiving cavity 15 for accommodating the elastic part 10, the first end of the clamping part 11 is fixed to the second end of the clamping piece (it can be integrally formed), and the second end is a pressing end, which provides a pressing position for the operator, and the clamping part 11 is provided with a first groove on one side close to the shunt bar, A rubber pad 12 is arranged inside the first groove to make it have a certain elasticity, so that it is suitable for pipes of more sizes (for example, the first pipe 1 and the second pipe 2 of different sizes). The movable end of the elastic part 10 is provided with a second through hole, and the elastic part 10 is sleeved on the branch flow strip through the second through hole. The connecting end of the elastic part 10 is fixed on the clamping part 11 and is located above the first groove (of course, the elastic part 10 can also be arranged at other positions, such as on the side wall of the connecting part 9). At the same time, a gap is left between the elastic part 10 and the connecting part 9, and the gap can provide deformation space for the elastic part 10.

[0037] When used specifically, Figure 4a and Figure 4b, by pressing the pressing end of the clamping part 11, the first groove is fitted with the first pipe 1 or the second pipe 2 (for pipes with different outer diameters, different forces can be applied to the clamping member to ensure that the inner wall of the first groove can fit pipes of different sizes). The friction between the two makes the two relatively fixed. At this time, the elastic part 10 is deformed under the extrusion, and its movable end approaches the first end of the connecting part 9, and the connecting part 9 also approaches the pipe; when the clamping member is moved, the clamping part 11 is released, the elastic part 10 is reset, and its movable end is away from the first end of the connecting part 9, while driving the clamping part 11 and the connecting part 9 to reset. In this state, the clamping member can be slid to the target position on the shunt flow strip at will.

[0038] Among them, since the outer diameters of the first pipe 1, the second pipe 2 and the locking handle 3 are inconsistent, during the movement of the clamp on the branch flow strip, the clamping part 11 can be expanded to the maximum extent, thereby ensuring that the first through hole and the second through hole are opened to the maximum extent to pass the locking handle 3.

[0039] In some embodiments, the outer diameter of the locking handle 3 increases from the first end to the second end, remains unchanged, and finally decreases again. Both ends are sloped toward the inside of the bypass strip to ensure that the clamp can pass through the locking handle 3 smoothly without getting stuck.

[0040] In some embodiments, the elastic portion 10 is made of rubber.

[0041] In some embodiments, an anti-slip protrusion is provided on the outer wall of the clamping portion 11 to prevent the operator from slipping when holding the clamping portion 11 for operation.

[0042] In some embodiments, a second groove cooperating with the bypass strip is also provided on the inner wall of the elastic portion 10, so that the contact area between the clamping member and the bypass strip is larger, thereby increasing friction and ensuring a fixing effect.

[0043] In other embodiments, the clamping member is composed of two symmetrical clamping blocks, and the two clamping blocks respectively include the above-mentioned connecting portion 9, the clamping portion 11 and the elastic portion 10; when fixing the clamping member to the bypass flow strip, the clamping portions 11 of the two clamping blocks are pressed at the same time so that the inner wall of the first groove fits tightly with the outer wall of the first pipe 1 or the second pipe 2, thereby achieving fixation; when the position of the clamping member needs to be adjusted, the clamping portions 11 on both sides of the bypass flow strip are loosened so that the clamping portions 11 are separated from the bypass flow strip, and the clamping member is slid to the specified position to complete the adjustment, and the operation is simple and convenient.

[0044] In some embodiments, to facilitate puncture, as shown in the attached Figure 7a-7cA bullet tip 18 is also provided at the front end (i.e., the end that first extends into the patient's body when used) of the above-mentioned ventriculoperitoneal shunt cleaning rod 17 (hereinafter referred to as the cleaning rod). Specifically, a second internal thread is provided at the front end of the cleaning rod 17, and a second external thread matching the second internal thread is provided at the tail of the bullet tip 18. Before puncture, the bullet tip 18 is installed at the front end of the cleaning rod 17, so as to facilitate the insertion of the cleaning rod 17 into the patient's body. After the front end of the cleaning rod 17 is inserted out, the bullet tip 18 is removed without affecting the normal use of the cleaning rod 17 (that is, a drainage tube can be directly set in the cleaning rod 17 for drainage; of course, a guide core or a guide wire can also be used to guide the drainage tube to pass out of the cleaning rod).

[0045] In summary, the present application comprehensively provides a ventriculoperitoneal shunt strip with adjustable length and freely adjustable holding position, which is more convenient and quick to use.

[0046] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0047] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
