Description

Technical Field

[0001] This utility model relates to the technical field of sealing abdominal surgical instruments, specifically to a sealing device for laparoscopic anastomosis instruments. Background Technology

[0002] Abdominal surgical instruments are commonly used in abdominal surgery, and their use requires sealing. Conventional sealing involves inflating a soft sheath and compressing it around the incision to form a seal with the liner. However, the sealing effect of an inflated soft sheath is not very reliable, and the other end of the soft sheath has poor sealing properties, making it prone to air leakage. On the one hand, this causes the pressure inside the soft sheath to decrease and prevents it from inflating, reducing the pressure between the soft sheath and the incision, resulting in air leakage around the incision and affecting the operation. On the other hand, the soft sheath before inflation requires pulling on the patient's surgical wound before the inflated soft sheath can be inserted, which is not only time-consuming and laborious, but also causes secondary injury to the patient. Utility Model Content

[0003] The purpose of this invention is to provide a sealing device for laparoscopic anastomosis instruments to solve the technical problems in existing devices.

[0004] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: a sealing device for laparoscopic anastomosis instruments, comprising a protective sleeve, a sealing panel and an air bladder, wherein the sealing panel is inserted into the protective sleeve, and the inner cavity of the sealing panel has several insertion holes communicating with the protective sleeve for inserting abdominal surgical instruments; the air bladder surrounds the bottom outer side of the protective sleeve, and the air bladder can automatically inflate when the sealing panel is inserted into the protective sleeve;

[0005] The protective sleeve has an installation groove at the center of its inner cavity. A hollow vertical cylinder is designed at the bottom center of the installation groove, penetrating the bottom of the protective sleeve. The top of the hollow vertical cylinder is movably sleeved with the sealing panel. Several guide holes communicating with the airbag are opened at the bottom of the installation groove located on the periphery of the hollow vertical cylinder. An elastic piston that can be inserted into the guide holes is movably sleeved on the hollow vertical cylinder.

[0006] The elastic piston can inflate the airbag under the pressure of the sealing panel, and can automatically deflate the airbag when it is released from the pressure of the sealing panel.

[0007] In a preferred embodiment of this utility model, the elastic piston component includes a slip ring and several guide pistons. The slip ring is slidably sleeved on the hollow vertical cylinder and is located in the gap formed by the hollow vertical cylinder and the mounting groove. Each guide piston is fixedly connected to the slip ring, and the end of each guide piston away from the slip ring is correspondingly slidably inserted into each of the insertion holes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, a sealing device for laparoscopic anastomosis instruments includes a protective sleeve 1, a sealing panel 2, and an airbag 3. The sealing panel 2 is inserted into the protective sleeve 1. The inner cavity of the sealing panel 2 has several insertion holes 4 that communicate with the protective sleeve 1 for inserting abdominal surgical instruments. The airbag 3 surrounds the bottom outer side of the protective sleeve 1. When the sealing panel 2 is inserted into the protective sleeve 1, the airbag 3 can automatically inflate.

[0023] A mounting groove 5 is provided at the center of the inner cavity of the protective sleeve 1. A hollow vertical cylinder 6 is designed at the bottom center of the mounting groove 5, which penetrates the bottom of the protective sleeve 1. The top of the hollow vertical cylinder 6 is movably sleeved with the sealing panel 2. Several guide holes 11 communicating with the airbag 3 are provided at the bottom of the mounting groove 5 located on the periphery of the hollow vertical cylinder 6. An elastic piston 7 that can be inserted into the guide holes 11 is movably sleeved on the hollow vertical cylinder 6.

[0024] The elastic piston 7 can inflate the airbag 3 under the pressure of the sealing panel 2, and can automatically deflate the airbag 3 when it is released from the pressure of the sealing panel 2.

[0025] The diameter of each insertion hole 4 is different, and the different diameters of the insertion holes 4 facilitate the insertion of different surgical instruments.

[0026] The device automatically inflates the airbag by installing and removing the sealing panel and the protective sleeve. The inflation of the airbag helps to stably fix the protective sleeve at the patient's surgical incision, and also makes it easier to insert the entire protective sleeve into the patient's surgical incision, avoiding expansion damage to the patient's incision during insertion.

[0027] Specifically, the elastic piston component 7 includes a slip ring 71 and several guide pistons 72. The slip ring 71 can be slidably sleeved on the hollow vertical cylinder 6, and the slip ring 71 is located in the gap formed by the hollow vertical cylinder 6 and the mounting groove 5. Each guide piston 72 is fixedly connected to the slip ring 71, and the end of each guide piston 72 away from the slip ring 71 is correspondingly slidably inserted into each insertion hole 4. Each guide piston 72 is sleeved with a return spring 73, and the two ends of the return spring 73 are respectively fixed to the bottom of the slip ring 71 and the mounting groove 5.

[0028] When the sealing panel 2 is not inserted into the protective sleeve 1, the airbag 3 is in a deflated state, that is, the airbag 3 is retracted into the side wall of the protective sleeve 1. At this time, there is no obvious outward protrusion of the side wall of the protective sleeve 1. The protective sleeve 1 can be smoothly inserted into the patient's surgical incision. After the protective sleeve 1 is fully inserted, the sealing panel 2 is then inserted into the protective sleeve 1. Because the diameter of the top of the protective sleeve 1 is larger than the diameter of the body, the protective sleeve 1 will not be completely inserted into the patient's body. At this time, the sealing panel 2 moves down along the mounting groove, gradually compressing during the downward movement. The slip ring 71, when compressed, drives the guide piston 72 to slide along the guide hole 11. At this time, the return spring 73 undergoes elastic deformation under the action of external force, and the guide piston 72 also introduces the gas in the guide hole 11 into the airbag 3. The airbag inflates, thus forming an I-shaped structure with the protective sleeve 1, thereby fixing and limiting the protective sleeve 1. Conversely, when the sealing panel 2 separates from the protective sleeve 1, the elastically deformed return spring 73 automatically resets, thereby extracting the gas from the airbag 3, causing the airbag to deflate, and the protective sleeve 1 to disengage from the limit, thus facilitating separation.

[0029] Furthermore, the outer wall of the sealing panel 2 is provided with an external thread 8, and the inner wall of the mounting groove 5 is provided with an internal thread that mates with the external thread 8.

[0030] This facilitates the installation and removal of the protective sleeve 1 and the sealing panel 2.

[0031] Furthermore, the inner cavity of the sealing panel 2 is provided with a ring 9 that can be slidably fitted onto the hollow vertical cylinder 6, and the ring 9 can be pressed into contact with the slip ring 71.

[0032] This allows the elastic piston 7 to slide in a straight line, ensuring the uniform inflation of the airbag 3.

[0033] Specifically, each insertion hole 4 is provided with several valves 10, and each valve 10 can form a complete circular surface.

[0034] This ensures a good sealing effect after each mechanical component is inserted.

[0035] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
