Description

Technical Field

[0001] The invention relates to the field of medical instruments, and more particularly to a neurosurgery ventricular drainage tube clamping device. Background Art

[0002] Ventricular drainage requires the drainage tube to be fixed to improve the safety and smoothness of drainage. However, traditional fixation methods often use gauze or tape to fix the drainage tube, which is not secure and the height and angle of the drainage tube cannot be adjusted according to actual needs, resulting in unsatisfactory drainage effects.

[0003] To this end, a Chinese patent with publication number "CN217593571U" announced "a neurosurgery ventricular drainage tube clamping device". The neurosurgery ventricular drainage tube clamping device uses a support plate, a connecting rod, a rotating shaft, and an adjusting mechanism to rotate the worm to drive the worm wheel to rotate, so that the rotating shaft and the support plate rotate, and the distance between the clamping plate and the suction cup is adjusted, thereby adjusting the support height. At the same time, through the use of a limiting mechanism and an installation mechanism, the angle between the suction cup and the connecting rod can be quickly adjusted, thereby changing the support direction of the clamping plate and adjusting the support angle.

[0004] However, in actual use, when clamping the drainage tube, the clamping effect of the semi-tubular clamping plate is used, and the general flow tube clamp is a hose structure, which uses its ability to be easily deformed to have a better drainage function. When the hard clamping plate clamps the hose, the hose will close toward the center, resulting in unstable clamping force of the clamping plate on the hose. At the same time, the closing of the hose will cause the flow of liquid to be blocked, affecting the drainage efficiency. Summary of the invention

[0044] like Figures 1 to 8 As shown, an embodiment of the present invention provides a neurosurgery ventricular drainage tube clamping device, including a ring body 1, a mounting bracket 2 which is integrally arranged in the outer ring structure of the ring body 1 and can be fixedly installed in a corresponding component, and three No. 1 rod body through holes 3 which are arranged in an annular array in the ring body 1 and connect the inner and outer rings of the ring body 1.

When the outer wall of the drainage tube is adsorbed on the circumferential inner wall of the arc-shaped clamping plate 413, the pressure on the upper hollow rod 47 is released. Under the action of the No. 1 coil spring 411, the arc-shaped clamping plate 413 drives the drainage tube to expand outward, so that the inner diameter of the drainage tube can normally achieve the drainage effect of the liquid.

[0046] like Figure 4 and Figure 5 As shown, the elastic telescopic adsorption mechanism 4 includes a No. 1 hollow shell 41, one end of the No. 1 hollow shell 41 is provided with a No. 1 fixed plate structure 42 which is an integral structure with it and fixedly installed at the end of the No. 1 rod body through hole 3, the interior of the No. 1 hollow shell 41 is provided with a No. 1 component active cavity 43, one end of the No. 1 hollow shell 41 is provided with a No. 2 rod body through hole 44 which connects one end of the No. 1 component active cavity 43 and the No. 1 rod body through hole 3, and the other .... The third rod body through hole 45 is formed at the end of the first hollow shell 41, and an inner movable plate 46 capable of axially moving along the first component movable cavity 43 is placed inside the first component movable cavity 43. One end of the inner movable plate 46 is provided with a lower hollow rod 410 which is an integral structure with it and passes through the second rod body through hole 44, and the other end of the inner movable plate 46 is provided with an upper hollow rod 47 which is an integral structure with it and passes through the third rod body through hole 45, and the inner movable plate 46, the upper hollow rod 47 and the lower hollow rod 410 are provided with a hollow rod 47 with one end in an open state. The top of the upper hollow rod 47 is provided with an air pressure discharge channel 49 which is connected to the No. 2 gas flow chamber 412 and has a manual valve installed inside. The upper hollow rod 47 is provided with three No. 1 gas flow holes 48 which are connected to the external space and the No. 2 gas flow chamber 412 on the outer circumferential surface near the air pressure discharge channel 49. The lower hollow rod 410 is provided with a No. 1 coil spring 411 in a compressed state on the outer periphery of the rod body located inside the No. 1 component active chamber 43. The rod body of the lower hollow rod 410 passes through the No. 1 rod body throughhole. 3. An arc-shaped clamping plate 413 is fixedly installed at the end, and an arc-shaped gas reserved cavity 414 is arranged inside the arc-shaped clamping plate 413. A plurality of adsorption holes 415 connecting the inner concave surface of the arc-shaped clamping plate 413 and the inner concave surface of the arc-shaped gas reserved cavity 414 are arranged inside the arc-shaped clamping plate 413.

The structural radius of the inner concave surface of the arc-shaped clamping plate 413 is consistent with the outer annular structural radius of the drainage tube.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, in order to achieve the gas adsorption fixing effect on the drainage tube, three push-type exhaust mechanisms 5 need to be set. The push-type exhaust mechanism 5 includes a second hollow shell 54 fixedly installed at the end of the upper hollow rod 47 and having a hollow interior, connected to the internal structure of the upper hollow rod 47, and a piston plate 511 placed inside the second hollow shell 54 and capable of extracting the gas inside the upper hollow rod 47 during the activity. When the outer wall of the drainage tube contacts the circumferential inner wall of the arc-shaped clamping plate 413, the telescopic rod 513 is reciprocally pressed, and with the cooperation of the second coil spring 512, the piston plate 511 will produce a reciprocating pressure. During the movement of the piston plate 511, the gas enters the gas limiting flow chamber 57 through the No. 1 gas flow hole 48 and the No. 1 gas one-way valve 59, and is discharged to the outside space through the gas limiting flow chamber 57 and the No. 2 gas one-way valve 510, which will cause the gas inside the upper hollow rod 47 to be continuously discharged outward. Similarly, the amount of gas inside the arc-shaped gas reserved chamber 414 will be reduced until the outer wall of the drainage tube is adsorbed and fixed on the circumferential inner wall of the arc-shaped clamping plate 413, and the pressing of the telescopic rod 513 can be stopped, thereby achieving a gas adsorption-type fixing effect on the drainage tube.

[0048] like Figure 6As shown, the push-type exhaust mechanism 5 includes a fixing ring 51 fixedly mounted on the rod body of the upper hollow rod 47, the outer circumferential surface of the fixing ring 51 is provided with a No. 1 gas flow channel 52 connecting the external space and one of the No. 1 gas flow holes 48, the circumferential surface of the fixing ring 51 is provided with two symmetrical No. 2 gas flow channels 53 whose internal structures are connected to the other two No. 1 gas flow holes 48, each of the No. 2 gas flow channels 53 is provided with a No. 2 hollow shell 54 at the end, the No. 2 hollow shell 54 is provided with a gas limiting flow cavity 57 connecting the internal hollow structure of the No. 2 gas flow channel 53, each of the gas limiting flow cavity 57 is provided with a No. 2 component active cavity 55 at the end, and the No. 2 hollow shell 54 is provided with a No. 4 rod body through hole 56 connecting the external space and one end of the No. 2 component active cavity 55. The outer circumferential surface of the No. 2 hollow shell 54 is provided with a No. 3 gas flow channel 58 connecting the external space and the gas limiting flow chamber 57.

One end of the piston plate 511 presses against one end of the No. 2 coil spring 512 in a compressed state, and the other end of the No. 2 coil spring 512 presses against the inner wall of the No. 2 component active chamber 55. The other end of the piston plate 511 is fixedly installed with a pressing telescopic rod 513 passing through the No. 4 rod body through-hole 56.

[0049] like Figures 1 to 3 , Figure 7 and Figure 8As shown, in order to prevent the drainage tube from being damaged due to excessive gas suction, an air pressure control mechanism 6 is required to be set up. The air pressure control mechanism 6 includes a No. 3 hollow shell 61 which is fixedly installed at the end of the No. 1 gas flow channel 52 and is hollow inside, a movable valve plate 66 which is placed inside the No. 3 hollow shell 61 and can allow external gas to enter the No. 1 gas flow channel 52 when moving, and a No. 3 coil spring 67 which is placed inside the No. 3 hollow shell 61 and can have an elastic damping effect on the movable valve plate 66. As the gas pressure decreases, the negative pressure will affect the gas pressure inside the active cavity 611 of the No. 3 component through the No. 1 gas flow channel 52. The gas pressure will act on the surface of the active valve plate 66, generating suction on the active valve plate 66. When the suction is greater than the elastic strength of the No. 3 coil spring 67, external gas will enter through the No. 5 gas flow hole 65, the movement gap of the active valve plate 66, the gas flow groove 69, etc. and flow back to the No. 2 gas flow cavity 412, and finally enter the arc-shaped gas reserved cavity 414, thereby reducing the suction of the gas on the outer wall of the drainage tube, thereby preventing the drainage tube from being damaged due to excessive gas suction.

[0050] like Figure 7 and Figure 8As shown, the air pressure control mechanism 6 includes a No. 3 hollow shell 61, a No. 3 component active cavity 611 is arranged inside the No. 3 hollow shell 61, a docking pipe 62 with an integral structure therewith is arranged at one end of the No. 3 hollow shell 61, a No. 2 fixed plate structure 63 with an integral structure therewith and fixedly installed at the end of the No. 1 gas flow channel 52 is arranged at one end of the No. 2 fixed plate structure 63 and the docking pipe 62, a No. 4 gas flow hole 64 connecting one end of the No. 3 component active cavity 611 and the hollow structure in the No. 1 gas flow channel 52 is arranged inside the No. 2 fixed plate structure 63 and the docking pipe 62, a No. 5 gas flow hole 65 connecting the external space and the other end of the No. 3 component active cavity 611 is arranged at the other end of the No. 3 hollow shell 61, and an active valve plate 66 capable of axially moving along the No. 3 component active cavity 611 is arranged inside the No. 3 component active cavity 611, A No. 3 coil spring 67 in a compressed state is placed at the end of the movable valve plate 66 facing the No. 4 gas flow hole 64, and a plurality of concave gas flow grooves 69 are arranged on the circumferential surface of the movable valve plate 66. A concave annular embedding groove 68 is arranged at the end of the movable valve plate 66 facing the No. 5 gas flow hole 65, and an annular sealing ring 610 is installed inside the annular embedding groove 68 of the movable valve plate 66. The elastic strength of the No. 3 coil spring 67 is less than the elastic strength of the No. 2 coil spring 512, and the thickness of the annular sealing ring 610 is greater than the depth of the annular embedding groove 68. The structural radius of the inner ring of the annular sealing ring 610 is greater than the structural radius of the No. 5 gas flow hole 65, and the structure of the outer ring of the annular sealing ring 610 is smaller than the distance between the gas flow groove 69 and the axial center line of the movable valve plate 66.

[0051] The workflow of the technical solution provided by the present invention is as follows:

[0052] When in use, the mounting bracket 2 is mounted on the fixed end of a universal bracket capable of controlling the angle and distance, and the universal bracket is fixedly mounted in the working area, and the hollow rod 47 is mounted on the universal bracket.

[0053] When the outer wall of the drainage tube hits the circumferential inner wall of the arc-shaped clamping plate 413, the reciprocating pressing of the telescopic rod 513, with the cooperation of the No. 2 coil spring 512, will cause the piston plate 511 to produce reciprocating motion. During the movement of the piston plate 511, the gas inside the upper hollow rod 47 will be continuously discharged outward. Similarly, the amount of gas inside the arc-shaped gas reserved chamber 414 will be reduced until the outer wall of the drainage tube is adsorbed and fixed on the circumferential inner wall of the arc-shaped clamping plate 413, and the pressing of the telescopic rod 513 can be stopped.

[0054] When the outer wall of the drainage tube is adsorbed on the circumferential inner wall of the arc-shaped clamping plate 413, the pressure on the upper hollow rod 47 is released. Under the action of the No. 1 coil spring 411, the arc-shaped clamping plate 413 will drive the drainage tube to expand outward, so that the inner diameter of the drainage tube can achieve the normal drainage effect of the liquid.

[0055] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
