Description

Technical Field

[0001] The utility model relates to the technical field of oral surgery auxiliary instruments, in particular to a three-way device special for oral surgery. Background Art

[0002] During existing oral surgeries, strong and weak negative pressure suction are used to keep the work area free of water and debris, providing the surgeon with a clear, dry surgical field. They can also be used to pull and push soft tissue within the mouth, ensuring adequate operating space and providing the surgeon with an optimal field of vision. Negative pressure can also be used to eliminate discomfort caused by mist and dust, ensuring patient comfort and safety, and preventing potential infection for both the surgeon and the patient. However, strong and weak negative pressure suction systems currently operate in separate lines, preventing nurses from using both strong and weak suction systems simultaneously during surgery, which reduces surgical efficiency and increases surgery time.

[0041] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following further elaborates the present utility model in conjunction with specific illustrations.

[0042] Refer to Figures 1-5 A three-way device dedicated for oral surgery shown, including:

[0043] Spherical joint assembly 100, the spherical joint assembly 100 is composed of an inner ring 110 and an outer ring 120 sleeved together, and the inner ring 110 can rotate relative to the outer ring 120;

[0045] The strong suction connector 300 is fixed on the outer side of the spherical joint assembly 100, connected to the external strong suction pipeline, and communicated with the negative pressure connector 200 when staggered with the inner ring 110;

[0046] The weak suction connector 400 is fixed on the outer side of the spherical joint assembly 100, connected to the external weak suction pipeline, and communicated with the negative pressure connector 200 when staggered with the inner ring 110;

[0047] The filter assembly 500 is installed on the negative pressure connector 200.

[0048] Among them, by rotating the inner ring 110, the pipeline connected to the negative pressure connector 200 is connected to the strong suction connector 300 or the weak suction connector 400, realizing the rapid switching between strong suction and weak suction;

[0049] Among them, the filter assembly 500 is provided to filter the solid debris, gingival tissue, etc. that enter the pipeline during oral surgery through strong suction and weak suction negative pressure adsorption, so as to prevent the solid debris and gingival tissue from entering and blocking the pipeline, affecting the intraoperative operation.

[0050] In some embodiments of the present invention, refer to Figure 1 and Figure 3 As shown, the negative pressure connector 200, the strong suction connector 300, and the weak suction connector 400 are distributed in an annular array and form a tee structure with the spherical joint assembly 100.

[0051] In some embodiments of the present invention, the diameter of the strong suction connector 300 is larger than the diameter of the weak suction connector 400 (not shown in the figure).

[0052] Among them, by changing the diameters of the strong suction connector 300 and the weak suction connector 400, it is convenient to distinguish between the strong suction connector 300 and the weak suction connector 400, facilitating the distinction between strong suction and weak suction to cooperate with the operation.

[0053] In some embodiments of the present invention, refer to Figure 3 and Figure 2 As shown, the outer ring 120 includes:

[0054] A sphere 121;

[0055] A friction sleeve 122, the friction sleeve 122 is fixed on the outer side of the sphere 121;

[0056] Blocking plates 123, there are two blocking plates 123, which are respectively fixed between the strong suction connector 300 and the negative pressure connector 200, and between the weak suction connector 400 and the negative pressure connector 200. The blocking plates 123 are adapted to be structures that limit the rotation angle of the inner ring 110.

[0057] Among them, the sphere 121 is divided into two sections, which are spliced to form a complete sphere 121, fixed together by welding, and the inner ring 110 is installed inside the sphere 121;

[0058] Among them, the friction sleeve 122 is integrally formed with the sphere 121, and the inner surface is relatively rough, which can increase the friction force of the inner ring 110 and prevent the inner ring 110 from rotating easily under the action of external force, affecting the sealing of the strong suction joint 300 or the weak suction joint 400;

[0059] Among them, the rotation range of the inner ring 110 is limited by the setting of the blocking plate 123, preventing the inner ring 110 from rotating too much and causing the strong suction joint 300 and the weak suction joint 400 to be opened simultaneously.

[0060] In some embodiments of the present invention, referring to Figure 2 and Figure 4 as shown, the inner ring 110 includes:

[0061] An incomplete sphere 111, which is rotatably installed inside the inner ring 110;

[0063] Among them, by rotating the incomplete sphere 111, the rubber gasket 112 blocks the strong suction joint 300 or the weak suction joint 400. At the same time, the incomplete setting of the incomplete sphere 111 can be normally blocked by the blocking plate 123, while ensuring that the negative pressure can act normally on the negative pressure joint 200;

[0064] Among them, the rubber gasket 112 is bonded to the incomplete sphere 111 and is pressed against the inner wall of the sphere 121, which can increase the friction force and ensure the sealing effect at the same time.

[0066] A rotating shaft 113, which is fixed to the outside of the incomplete sphere 111 and extends through the sphere 121 to the inside of the friction sleeve 122;

[0067] A rotating key 114, which is installed on the rotating shaft 113 and rubs against the inner wall of the friction sleeve 122.

[0068] Among them, the rotary key 114 is detachably screwed on the outside of the rotating shaft 113, and drives the incomplete sphere 111 to rotate under the action of human force to adjust the position of the incomplete sphere 111. At the same time, the connection between the rotating shaft 113 and the sphere 121 is wrapped by a rubber gasket 112, which can effectively seal.

[0069] In some embodiments of the present utility model, referring to Figure 2 and Figure 5 as shown, the filtering assembly 500 includes:

[0070] A pipe joint 510, which is screwed to the opening of the negative pressure joint 200;

[0074] Among them, the filter screen 530 is detachably fixed inside the pipe joint 510, and filters the incoming solid debris and gingival tissue;

[0075] Among them, through the setting of the sealing ring 520, the connection between the pipe joint 510 and the negative pressure joint 200 can be sealed to prevent gas from entering.

[0076] The working method of the present utility model:

[0077] During installation, the sealing ring 520 is sleeved on the outside of the negative pressure joint 200, and the pipe joint 510 is screwed on the outside of the negative pressure joint 200, and the sealing ring 520 is squeezed;

[0078] Then the corresponding pipes are sequentially installed on the pipe joint 510, the strong suction joint 300, and the weak suction joint 400 for use;

[0079] When increasing the negative pressure intensity, rotate the rotary key 114 so that the rotary key 114 drives the incomplete sphere 111 to face the weak suction joint 400 and contact the baffle 123 to block the weak suction joint 400, so that the strong suction joint 300 is connected to the negative pressure joint 200;

[0080] When reducing the negative pressure intensity, rotate the rotary key 114 in the reverse direction so that the rotary key 114 drives the incomplete sphere 111 to face the strong suction joint 300 and contact the baffle 123 to block the strong suction joint 300, so that the weak suction joint 400 is connected to the negative pressure joint 200.
