In order to achieve the purpose, the utility model adopts the technical proposal that: the fixable arthroscope access sleeve comprises a tube body, wherein the tube body is of a hollow cylindrical structure, two ends of the tube body are respectively provided with an open end and an access end, a freely movable clamping ring is arranged between the open end and the access end, and the open end is provided with a fixing cover with a plurality of bayonets and a fixing belt with a boss;

the fixed band is the band structure, and fixed band one end and open end fixed connection, the bayonet socket on the fixed cover is passed to the other end of fixed band, and bayonet socket and boss coincide each other.

Further, a sealing sheet is arranged inside the tube body, and a notch is formed in the center of the sealing sheet and is Y-shaped.

Furthermore, the fixed cover is movably connected with the open end, and the center of the fixed cover is of a hollow structure.

To sum up, the utility model has the advantages of it is following:

1. the utility model provides a can fix arthroscope sleeve pipe of going into the way at treating operation joint position, can effectively prevent the sleeve pipe and remove, and the change apparatus of being convenient for is favorable to the operation to go on smoothly.

2. The utility model discloses be provided with the structure of fixed band, the cooperation has the fixed lid structure of bayonet socket, can encircle the body fixedly, and convenient to use is swift in the operation.

Detailed Description

The following describes the embodiments of the present invention in detail with reference to the attached drawings.

In one embodiment of the present invention, as shown in fig. 1-4, a fixable arthroscope access sleeve is provided, which comprises a tube body 1.

Wherein, body 1 is hollow cylinder structure, and body 1's one end is provided with open end 2, as the insertion port of apparatus. An inlet end 3 is arranged at one end of the tube body 1 far away from the open end 2 and is used as one end of the tube body 1 contacting with the operation incision. It can be understood that the open end 2 and the inlet end 3 are respectively disposed at two ends of the tube body 1.

In a preferred embodiment of the invention, a freely movable snap ring 4 is arranged between the open end 2 and the access end 3 of the tube body 1 for fixing the incision of the tissue between the access end 3 and the snap ring 4. That is, the outer side of the pipe body 1 should be provided with a structure capable of moving with the matching snap ring 4, and the structure can be a thread structure or other structures capable of realizing the movement of the snap ring 4. It will be appreciated that the snap ring 4 should act to secure the incision when securing the incision between the access end 3 and the snap ring 4.

In some optional embodiments of the present invention, the open end 2 is provided with a fixing cap 5 having a bayonet and a fixing band 7 having a boss 6, and the other end of the fixing band 7 can pass through the bayonet of the fixing cap 5, so as to fix the pipe body 1 around the pipe body. That is, the fixing cap 5 is a hollow circular ring structure which can cover the circular ring structure of the open end 2, and it is understood that the inner diameter of the fixing cap 5 should be larger than the outer diameter of the open end 2. The fixed cover is provided with a bayonet structure similar to the bayonet structure on a belt; the fixing belt 7 is a belt-shaped structure, surrounds the pipe body 1 and penetrates through the bayonet on the fixing cover 5, and can fix the pipe body 1 in a surrounding mode.

In the preferred embodiment of the present invention, the boss 6 on the fixing band 7 is uniformly provided with a plurality of protrusions, and can be used in cooperation with the bayonet on the fixing band 5 to fix the fixing band.

As shown in fig. 3 and 4, in some embodiments of the present invention, a sealing sheet 8 is further disposed inside the tube body 1, and a cut 9 shaped like a "Y" is disposed at the center of the sealing sheet 8 to allow the passage of instruments. That is, the instrument can be inserted through the cut-out 9 in the middle of the sealing disc 8.

Preferably, the utility model provides a material that can fix all structures in arthroscope access sleeve pipe is the silica gel material.
