Technical Field

[0001] The utility model relates to the field of surgical instruments, in particular to a disposable sealing protective sleeve for surgical instruments. Background Art

[0002] Many medical devices are needed in clinical surgery. For example, puncture requires components such as puncture sleeves, puncture needles and drainage tubes. During the operation, body fluids will flow out from the inside. In order to prevent the outflowing fluid from splashing and backflowing, a sealing protective sleeve is usually set on the puncture sleeve for isolation. When the existing sealing protective sleeve is set, the port is put on the side wall of the instrument, and then a binding belt is used to wrap it to squeeze the port to fit the instrument wall, and finally an adhesive tape is used to wrap it to achieve fixation. The operation is cumbersome and the practicality is poor. Utility Model Content

[0004] The technical solution of the utility model: a disposable sealing protective cover for intraoperative instruments, comprising a protective cover body, one end of which is provided with a sealing ring; an annular shrinkage cavity is provided in the sealing ring, and a first through-opening and a second through-opening which are connected to the shrinkage cavity are provided on the side of the sealing ring; a shrinkage belt is passed through the shrinkage cavity, and the shrinkage belt comprises a fixed end and an insertion end, and a crossing portion is provided between the fixed end and the insertion end; a ring-opening sealing belt corresponding to the outer end of the sealing ring is provided on the side of the fixed end; the crossing portion is located in the first through-opening and is provided with a socket which fits with the insertion end; the insertion end is located in the second through-opening; a first adhesive surface for connecting the insertion end and the side of the sealing ring is provided on the fixed end; a second adhesive surface is provided on the ring-opening sealing belt.

[0005] In the disposable intraoperative instrument sealing protective cover mentioned above, the fixed end is provided with a third adhesive surface for connecting to the side surface of the sealing ring.

[0006] In the aforementioned disposable intraoperative instrument sealing protective cover, the length of the ring sealing band is greater than the circumference of the sealing ring.

[0007] In the aforementioned disposable intraoperative instrument sealing protective cover, the intersection portion is matched with the first through-opening, and the side of the intersection portion is evenly distributed with first anti-retraction teeth facing the first through-opening.

[0008] In the aforementioned disposable intraoperative instrument sealing protective cover, the insertion end is matched with the second through-hole, and the side of the insertion end is evenly distributed with second anti-retraction teeth facing the second through-hole.

[0009] In the aforementioned disposable intraoperative instrument sealing protective cover, the opening of the sealing ring has a chamfered transition.

[0010] Compared with the prior art, when the present utility model is in use, the tail end of the instrument is sleeved into the sealing ring. After the sealing ring is aligned with the side wall of the instrument, the insertion end passes through the socket to form a ring surrounding the instrument. Subsequently, the insertion end and the fixed end are pulled simultaneously, and the length of the contraction belt in the contraction cavity is shortened. The side wall of the instrument is squeezed and fitted through the sealing ring. Then, the fixed end is continuously wound around the sealing ring, and the insertion end and the sealing ring are fixed through the first bonding surface, so as to complete the preliminary sealing by completely fixing the contraction belt. Finally, the second bonding surface of the ring mouth sealing belt is bonded to the side wall of the instrument to achieve complete sealing. Therefore, the present utility model can quickly set the protective sleeve body on the intraoperative instrument, with convenient operation. Moreover, the insertion end of the present utility model directly passes through the crossing part, effectively avoiding the generation of gaps due to the complete overlap of the two, and having good sealing reliability.
