Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical consumables technology, and in particular relates to a flushing and suction connector and a suction tube. Background Technology
[0002] In some surgical procedures, continuous cleaning of the incision site is required. For example, in laparoscopic surgery, a cleaning tube and a suction tube need to be installed. The cleaning tube sprays cleaning fluid, and then the suction tube simultaneously aspirates blood and loose tissue.
[0003] Current suction tubes typically have a ring of side holes on the bottom sidewall to prevent the bottom port from being blocked by tissue during negative pressure suction. However, the diameter of these side holes is not large, and the bottom port often gets blocked, resulting in low suction efficiency. Furthermore, the suction tubes are lightweight and have buoyancy in liquid environments, causing the bottom to float and hindering continuous suction, thus affecting overall efficiency. Utility Model Content
[0004] In view of the above problems, the purpose of this utility model is to provide a flushing suction connector and suction tube, which aims to solve the above technical problems.
[0005] The present invention adopts the following technical solution:
[0006] On one hand, the flushing suction connector includes an integrally formed outer shell and an inner tube. A ring of suction holes is formed between the outer shell and the inner tube. A guide hole is opened on the middle side wall of the outer shell at the corresponding position of each suction hole. Both ends of the inner tube are exposed outside the outer shell. A partition is provided inside the inner tube and below the guide hole. There is also a counterweight column inside the bottom of the inner tube. A baffle is vertically provided at the bottom position of each suction hole.
[0007] Furthermore, a fixing cap is provided at the bottom of the inner tube, which is used to fix the counterweight column.
[0008] Furthermore, the bottom surface between the outer shell and the inner tube is an arc-shaped surface, and the position of the arc-shaped surface is higher than the bottom edge of the outer shell.
[0009] On the other hand, the suction tube, including the flushing suction connector, also includes a main tube, the end of which is sealed to the top of the inner tube of the flushing suction connector.
[0010] Furthermore, a T-junction is connected to the main pipe, and a side tube is connected to all the switching ports of the T-junction, with a one-way airbag at the end of the side tube.
[0011] The beneficial effects of this utility model are as follows: This utility model connects a suction connector to the bottom of the suction tube. The suction connector includes an inner tube and an outer shell. On the one hand, the bottom of the inner tube protrudes from the outer shell, forming an annular suction port between the inner tube and the outer shell. The suction port has a large area and will not be blocked by the body tissue, which can significantly improve the suction efficiency. On the other hand, a counterweight column is also fixed at the bottom of the inner tube, which increases the weight of the suction connector, so that the bottom of the suction tube will not float and ensure the stability of the suction.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0017] like Figure 1-2 As shown, the flushing suction connector provided in this embodiment includes an integrally formed outer shell 1 and inner tube 2. A ring of suction holes 3 is formed between the outer shell 1 and the inner tube 2. A guide hole 4 is opened on the middle side wall of the outer shell 1 at a position corresponding to each suction hole 3. Both ends of the inner tube 2 are exposed outside the outer shell 1. A partition 5 is provided inside the inner tube 2 and below the guide hole 4. There is also a counterweight column 6 inside the bottom of the inner tube 1. A baffle 7 is vertically arranged at the bottom position inside each suction hole 3.
[0018] In this structure, the bottom space between the outer shell and the inner tube forms an annular suction port, and the outer circumference of the inner tube has a ring of suction holes. A guide hole is located between the upper part of the sidewall of the suction holes and the inner tube. Since the suction port is annular, this is further considered as a preferred structure, such as... Figure 1 As shown, the bottom surface between the outer shell and the inner tube is an arc-shaped surface, that is, the bottom surface of the suction port is an arc-shaped surface, and the position of the arc-shaped surface is higher than the bottom edge of the outer shell. When the rinsing suction connector is placed into the cleaning area, the annular suction port will not be blocked by the tissue in the cleaning area, and all suction holes can draw out the rinsing fluid, ensuring the effectiveness of use.
[0019] Meanwhile, each suction hole 3 has a baffle plate, which is used to prevent slightly larger tissue fragments from being sucked into the suction tube and blocking it, especially if they get stuck in the guide hole 4 and block the inner tube.
[0020] In addition, another feature of this structure is the presence of a counterweight column at the bottom of the inner tube. This increases the weight of the suction connector, allowing it to sink to the bottom of the liquid for easy extraction of the cleaning fluid and ensuring stability. As shown in the diagram, a fixing cap 8 is also provided at the bottom of the inner tube 1. The fixing cap 8 is used to secure the counterweight column 6. The fixing cap 8 is fused to the bottom of the inner tube and will not detach.
[0021] like Figure 3 As shown, this embodiment also provides a suction tube, including the flushing suction connector 100 and a main tube 200, the end of which is sealed to the top of the inner tube of the flushing suction connector. In use, the flushing suction connector is placed on the cleaning area, and the area is flushed with the flushing tube. Simultaneously, the main tube of the suction tube is connected to a negative pressure source to extract the flushing fluid. Additionally, a T-junction 300 is connected to the main tube 200, and a side tube 400 is connected to the switching port of the T-junction 300. The end of the side tube 400 has a one-way airbag 500. Normally, the port of the T-junction corresponding to the side tube is closed. If a large amount of free tissue fragments still block the bottom of the suction hole, the negative pressure source can be turned off first, the suction tube removed from the body, and then the T-junction switched to the side tube. By pressing the one-way airbag, the free tissue fragments can be flushed out, and then the tube can be used again. This method is simple and convenient, and can quickly solve the problem of blocked suction holes.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
