Description

Technical Field

[0001] The utility model relates to the technical field of electric staplers, in particular to an internal transmission connection sealing mechanism for staplers. Background Art

[0002] Electric staplers are used in open or laparoscopic surgical procedures for the resection, transection, and anastomosis of the lungs, bronchial tissue, stomach, and intestines. They are generally divided into disposable or reusable staplers. They are medical devices that replace traditional manual suturing. Due to the development of modern science and technology and the improvement of manufacturing technology, the staplers used in clinical practice are reliable in quality, easy to use, strict, and of appropriate tightness. In particular, their advantages such as fast suturing, simple operation, and few side effects and surgical complications have made it possible to remove tumors that were previously inoperable.

[0003] Deficiencies of existing technology:

[0004] Currently, surgical instruments must ensure that the parts that come into contact with patients are sterile. Some surgical instruments need to be connected to some mechanisms for operation, such as mobile power supplies, energy packs, etc. These mechanisms are generally provided in a non-sterile or simply disinfected manner. Therefore, it is necessary to ensure that these mechanisms will not contaminate the parts of the instrument that may come into contact with the patient during the use of the instrument, causing bacterial infection; common sealing mechanisms can easily cause seal failure due to wear at the transmission connection parts, and cannot form an effective bacteria barrier, posing a great risk to the operation. Utility Model Content

[0005] The purpose of the present utility model is to provide a transmission connection sealing mechanism for the internal of anastomosis device, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a sealing mechanism for internal transmission connection of an anastomosis device, comprising a transmission shaft, the transmission shaft being connected to a first sealing assembly and a second sealing assembly, the first sealing assembly comprising:

[0007] A sealing housing, the sealing housing being arranged outside the transmission shaft;

[0008] A sealing cover, the sealing cover is connected to the sealing housing, and the transmission shaft is connected to the sealing cover and is disposed inside the sealing housing;

[0009] A sealing ring is arranged on the outer ring of the transmission shaft.

[0010] Preferably, the second sealing assembly includes a boss, which is arranged inside the sealing housing and is arranged on the supporting surface of the outer ring of the transmission shaft corresponding to the sealing cover.

[0011] Preferably, the sealing cover is provided with a groove, and the sealing ring corresponds to the groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The invention relates to an internal transmission connection sealing mechanism for an anastomosis device, which comprises a first sealing component and a second sealing component. The first sealing component comprises a sealing shell, a sealing cover and a sealing ring, and the second sealing component comprises a boss, which is arranged inside the sealing shell. The boss is arranged on the supporting surface of the outer ring of the transmission shaft and corresponds to the sealing cover to form a labyrinth sealing structure. The first sealing component and the second sealing component form a double seal and cooperate with each other to effectively block bacteria, prevent the sealing mechanism from failing during operation, and avoid surgical risks.
