Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-clogging suction tube. Background Art

[0002] Aspirator is one of the necessary medical devices in surgical operation. It can remove various tissue fluids, blood, fat fluid, debris and other materials in the body cavity through the suction tube connected to the negative pressure device to make the surgical field clear and reduce the risk of contamination. The suction tube is usually a straight round tube, but this type of suction tube is easily blocked when sucking non-liquid materials such as debris, thus affecting the progress of the operation.

[0003] In order to prevent the suction tube from being blocked, the patent document with announcement number CN219558229U proposes an anti-blocking detachable suction tube. The technology has a first suction hole and a second suction hole on the suction tube head. The first suction hole and the second suction hole are set to be through holes with an outer contour smaller than the inner contour to prevent blockage. At the same time, the original suction tube is divided into several sections to facilitate cleaning of internal debris. However, after careful analysis by the applicant, it was found that the technology still has the following technical problems in practical application:

[0004] 1. When the outer diameter of the debris is larger than the inner diameter of the suction hole, the debris cannot be effectively sucked away, and these large particles of debris need to be manually clamped out by the doctor, which not only affects the progress of the operation, but also increases the difficulty of the operation.

[0005] 2. When large particles of debris are sucked into the suction tube and cause blockage, the negative pressure needs to be stopped and the suction tube needs to be manually disassembled and cleaned to remove the blockage. This process is complicated and also affects the smooth progress of the operation.

[0006] 3. This technology uses a finger to press the second suction hole on the side wall to adjust the negative pressure suction force, which is less practical. Utility Model Content

[0007] The purpose of the utility model is to overcome the above technical problems existing in the prior art, and to provide an anti-clogging suction tube. The utility model is provided with a spiral sleeve on the suction main tube that can be controlled to rotate relative to each other. According to the different types of materials to be sucked, by controlling the spiral sleeve and the suction main tube to rotate relative to each other, on the one hand, it is convenient to steplessly adjust the size of the negative pressure suction force to ensure a faster and more effective suction effect; on the other hand, it is possible to form a storage space for large-particle debris at the outer end of the suction main tube, which is convenient for the effective absorption of large-particle debris, and when there are many large particles absorbed in the storage space, the storage space can be cancelled by relatively rotating the spiral sleeve and the suction main tube, so that the large-particle debris can be removed at one time. The utility model solves the technical problems that affect the surgical process, such as the inability of the existing suction tube to absorb large-particle debris, the need to manually disassemble and clean the suction tube when blocked, and the inconvenience of adjusting the negative pressure suction force by finger pressing.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] A clogging-proof suction tube comprises a suction main tube, wherein the suction main tube comprises a negative pressure connection end and a suction end, wherein the end face of the suction end is provided with a main suction hole, and the side wall of the suction end is provided with a side suction hole; a spiral sleeve is provided on the suction main tube, and the spiral sleeve / suction main tube is rotated by an external force, so that relative movement can occur between the spiral sleeve and the suction main tube, and during relative movement, the suction end can be located outside the spiral sleeve, or the suction end can be located inside the spiral sleeve and a storage space can be formed by using the spiral sleeve.

[0010] The relative movement between the suction main pipe and the spiral sleeve under external force rotation means that the suction main pipe / spiral sleeve is controlled to be stationary, and the spiral sleeve / suction main pipe is rotated by external force, so that the spiral sleeve / suction main pipe can rotate and move relative to the suction main pipe / spiral sleeve.

[0011] The outer surface of the suction main pipe is provided with a spiral slide rail / slide groove, and the inner surface of the spiral sleeve is provided with a corresponding spiral slide groove / slide rail.

[0012] The spiral slide rail / slide groove is located between the middle part of the suction main pipe and the suction end, and the spiral sleeve can be inserted into the suction main pipe from the suction end, or detached from the suction main pipe from the suction end.

[0013] A partition is provided in the middle of the main suction hole to separate the main suction holes.

[0014] The number of the side suction holes is multiple, and the side suction holes are distributed along the axial direction of the suction main pipe.

[0015] The spiral sleeve is provided with anti-slip grooves.

[0016] The advantages of adopting the utility model are:

[0017] 1. The key improvement of the utility model is that a spiral sleeve is provided on the suction main pipe. When the spiral sleeve / suction main pipe is rotated by external force, the spiral sleeve and the suction main pipe can rotate relative to each other. During the relative rotation, the suction end and the side suction hole can be located outside the spiral sleeve, or the suction end can be located inside the spiral sleeve and the spiral sleeve can be used to form a storage space outside the suction end. Therefore, its advantages are as follows:

[0018] Firstly, the structure in which the spiral sleeve is spirally connected to the suction main pipe ensures that the suction main pipe and the spiral sleeve will not move relative to each other when not rotated by external force, and will only move relative to each other steplessly when rotated by external force. This allows the suction main pipe and the spiral sleeve to be well fixed and stopped at any required relative position, and there is no axial movement between the two during movement, thereby making the product more stable and reliable during suction operation.

[0019] Secondly, when the side suction hole is located in the spiral casing, the spiral cooperation between the inner wall of the spiral casing and the outer wall of the suction main pipe can ensure the airtightness between the inner wall of the spiral casing and the outer wall of the suction main pipe. Under the limitation of a small spacing, the side suction hole can basically be blocked without affecting the negative pressure of the main suction hole, which is conducive to using only the main suction hole to suck materials.

[0020] Again, when it is necessary to absorb materials containing large particles of debris, the suction end can be located inside the spiral sleeve. At this time, the suction main pipe can use the spiral sleeve to form a storage space for large particles of debris outside the suction end. In this state, the large particles of debris will be adsorbed in the storage space, thereby achieving effective absorption of large particles of debris in the body cavity.

[0021] Furthermore, when there are a lot of large particles of debris absorbed in the storage space and block the main suction hole, the suction tube can be moved aside as a whole, and then the relative movement between the suction main tube and the spiral sleeve can be controlled to make the storage space formed between the suction main tube and the spiral sleeve disappear, and at the same time, the side suction hole on the side wall of the suction end can extend out of the spiral sleeve. In this way, on the one hand, the stacked large particles of debris can be pushed out of the storage space to unblock the main suction hole, and on the other hand, the side suction hole can be used to release the negative pressure state of the suction main tube, thereby quickly eliminating the blockage of the main suction hole without disassembling and cleaning the suction tube. In actual applications, through the aforementioned repeated operations, it is possible to more quickly achieve effective absorption of large particles of debris, and better relieve the negative pressure of the suction main tube and the blockage of the main suction hole, thereby ensuring the smooth progress of the operation.

[0022] Finally, when it is necessary to suck liquid that will not cause blockage, the suction end and the side suction hole can be located outside the spiral casing. By steplessly adjusting the negative pressure suction force, the main suction hole and the side suction hole at the suction end can be used to suck the liquid, which is beneficial to increase the liquid suction speed.

[0023] In summary, the utility model controls the relative movement of the spiral sleeve and the suction main pipe according to the different types of materials to be sucked (for example, materials containing large particles of debris and liquids that will not cause blockage), so that the suction end is located inside the spiral sleeve or extends outside the spiral sleeve. On the one hand, it can facilitate stepless adjustment of the negative pressure suction force to ensure faster and more effective suction effect; on the other hand, it can form a storage space for large particles of debris at the outer end of the suction main pipe, which is convenient for the effective absorption of large particles of debris, and when there are many large particles absorbed in the storage space, the large particles of debris can be removed at one time by rotating the suction main pipe or the spiral sleeve. It has the technical effects of being able to adjust the negative pressure suction force according to needs, effectively absorb large particles of debris, prevent the suction main pipe from being blocked, quickly unblock the storage space when it is blocked, and effectively ensure the progress of the operation.

[0024] 2. The utility model is provided with a main suction hole and a side suction hole on the end face and the side wall of the suction end respectively. By cooperating with the spiral sleeve, the suction tube is suitable for effectively absorbing different types of materials and has the advantage of steplessly adjusting the size of the negative pressure suction force.

[0025] 3. The spiral sleeve in the utility model can be inserted into the suction main pipe from the suction end, or detached from the suction main pipe from the suction end, which has the advantages of simple and convenient assembly or disassembly.

[0026] 4. The utility model can further effectively prevent large particles of slag materials from entering the suction main pipe through the partition, and has the technical effect of preventing the suction main pipe from being blocked.

[0027] 5. The utility model can increase the friction between human fingers and the spiral sleeve through the anti-skid pattern, which is anti-skid and convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1-4 As shown, the utility model provides an anti-clogging suction tube, including a suction main tube 1, the suction main tube 1 includes a negative pressure connection end 2 and a suction end 3, the negative pressure connection end 2 is used to connect a negative pressure device, the suction end 3 includes an end face and an end portion close to the end face, the end face of the suction end 3 is provided with a main suction hole 8, and the side wall of the suction end 3 is provided with a side suction hole 9. In actual application, the suction main tube 1 extends into the body cavity through the suction end 3, and uses the main suction hole 8 and / or the side suction hole 9 to absorb liquid, debris, etc.

[0038] The anti-clogging suction tube also includes a spiral sleeve 4, which is sleeved on the suction main pipe 1 with a spiral structure. Under the premise that the suction main pipe 1 or the spiral sleeve 4 is not subject to external force rotation control, the spiral sleeve 4 is positioned on the suction main pipe 1, and no relative movement occurs between the suction main pipe 1 and the spiral sleeve 4. When the suction main pipe 1 or the spiral sleeve 4 is subject to external force rotation control, the suction main pipe 1 and the spiral sleeve 4 can move relative to each other, and during the relative movement, the suction end 3 and the side suction hole 9 can be located outside the spiral sleeve 4, or the suction end 3 can be located inside the spiral sleeve 4 and the spiral sleeve 4 can be used to form a storage space outside the suction end 3. Among them, the distance between the spiral sleeve 4 and the suction main pipe 1 is small. When the side suction hole 9 is inside the spiral sleeve 4, the suction main pipe 1 and the threaded sleeve 4 can basically prevent the side suction hole 9 from communicating with the outside world, and its influence on the negative pressure in the main suction hole 8 can be basically ignored.

[0039] It should be noted that the above-mentioned relative movement between the suction main pipe 1 and the spiral sleeve 4 under the external force rotation means: the suction main pipe 1 is controlled to be stationary, and the spiral sleeve 4 is rotated by external force, so that the spiral sleeve 4 can rotate and move relative to the suction main pipe 1, thereby realizing the position adjustment between the spiral sleeve 4 and the suction main pipe 1. Or: the spiral sleeve 4 is controlled to be stationary, and the suction main pipe 1 is rotated by external force, so that the suction main pipe 1 can rotate and move relative to the spiral sleeve 4, thereby realizing the position adjustment between the suction main pipe 1 and the spiral sleeve 4.

[0040] According to another preferred embodiment of the present utility model, Figure 1-4As shown, the outer surface of the suction main pipe 1 is provided with a spiral slide rail 6 or a spiral slide groove, and correspondingly, the inner surface of the spiral sleeve 4 is provided with a corresponding spiral slide groove 7 / spiral slide rail. The spiral slide rail 6 cooperates with the spiral slide groove 7 to enable the suction main pipe 1 and the spiral sleeve 4 to rotate and move relative to each other. In practical application, by controlling the rotation of the spiral sleeve 4 / suction main pipe 1, the suction main pipe 1 and the spiral sleeve 4 can achieve stepless relative movement, effectively avoiding movement during adjustment.

[0041] It should be noted that the above-mentioned spiral slide rail 6 or spiral slide groove is located between the middle part of the suction main pipe 1 and the suction end 3, and the spiral sleeve 4 can be inserted into the suction main pipe 1 from the suction end 3, or detached from the suction main pipe 1 from the suction end 3, so that the installation and disassembly of the spiral sleeve 4 and the suction main pipe 1 is simpler and more convenient.

[0042] According to another preferred embodiment of the present invention, the number of the main suction holes 8 can be one or more (including two). When the number of the main suction holes 8 is one, the diameter of the main suction hole 8 is smaller than the inner diameter of the suction main pipe 1, thereby preventing large particles of debris from entering the suction main pipe 1 and causing blockage. When the number of the main suction holes 8 is multiple, the multiple main suction holes 8 can be separated by partitions, thereby playing a role in selectively preventing debris of different sizes from entering the suction main pipe 1 and preventing it from being blocked.

[0043] According to another preferred embodiment of the utility model, there are multiple side suction holes 9, and the side suction holes 9 are distributed along the axial direction of the suction main pipe 1. For example, there may be four side suction holes 9, and the four side suction holes 9 may be distributed in a straight line or in a spiral in the axial direction of the suction main pipe 1. The multiple side suction holes 9 can be used to steplessly adjust the negative pressure suction force of the suction main pipe 1, thereby improving the suction effect of the material.

[0044] It should be noted that the present embodiment does not limit the shapes and sizes of the main suction holes 8 and the side suction holes 9, which can be set accordingly according to requirements.

[0045] According to an optional embodiment of the utility model, an anti-slip pattern 5 is provided on one end of the spiral sleeve 4 close to the negative pressure connection end 2. The anti-slip pattern 5 can be a stripe structure or a raised structure, thereby increasing the anti-slip friction between the finger and the spiral sleeve 4.

[0046] According to the type of material to be sucked, the suction tube of the utility model has two states when used, which are as follows:

[0047] 1. If Figure 5 , 6As shown, when it is necessary to suck materials containing large particles of debris, the suction main pipe 1 and the spiral sleeve 4 are first controlled to move relative to each other, so that the suction end 3 of the suction main pipe 1 is located in the spiral sleeve 4, and the side suction hole 9 is located in the spiral sleeve 4, so that a storage space is formed outside the end of the suction end 3 (specifically, Figure 5 The cavity between the right end of the middle suction main pipe 1 and the spiral sleeve 4). Then the negative pressure machine is turned on, and suction begins under the action of negative pressure. Large particles of debris are sucked and stored in the storage space, thereby achieving effective suction of large particles of debris in the body cavity.

[0048] When there are a lot of debris stacked in the storage space and the main suction hole 8 is blocked, the suction effect (amount) of the suction main tube 1 is reduced. At this time, the suction tube can be moved aside as a whole, and then the storage space formed between the suction main tube 1 and the spiral sleeve 4 is made to disappear by controlling the relative rotation between the suction main tube 1 and the spiral sleeve 4, and at the same time, the side suction hole 9 on the side wall of the suction end 3 is extended out of the spiral sleeve 4. In this way, on the one hand, the stacked large-particle debris can be pushed out of the storage space to remove the blockage of the main suction hole 8, and on the other hand, the side suction hole 9 can be used to release the negative pressure state of the suction main tube 1, so as to quickly eliminate the blockage of the main suction hole 8 without disassembling and cleaning the suction tube. In practical applications, through the above-mentioned repeated operations, it is possible to more quickly achieve effective absorption of large-particle debris, and better relieve the negative pressure of the suction main tube 1 and the blockage of the main suction hole 8, thereby ensuring the smooth progress of the operation.

[0049] 2. If Figure 7 , 8 As shown, when it is necessary to absorb liquid that will not cause blockage, the suction end 3 and the side suction hole 9 can be located outside the spiral sleeve 4. At this time, the main suction hole 8 and the side suction hole 9 can be used to absorb the liquid, thereby increasing the liquid absorption speed.

[0050] In summary, the utility model adopts the above-mentioned specific structure. When sucking different types of materials, it has the technical effect of being able to adjust the size of negative pressure suction as needed, effectively sucking large particles of debris, preventing the suction main pipe 1 from being blocked, and being able to quickly unblock the storage space when it is blocked, and effectively ensuring the progress of the operation.

[0051] The above description is only a specific implementation method of the present utility model. Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes; all disclosed features, or all methods or steps in the process, except for mutually exclusive features and / or steps, can be combined in any way.
