Abstract
A puncture outfit for operation with blood holding and outputting functions relates to the technical field of medical appliances. Comprises a cannula and a puncture core, and is characterized in that: the sleeve pipe is cylindrical and arranges perpendicularly downwards, and sheathed tube lower extreme periphery is provided with the annular of round arch, is provided with round upper end open-ended blood backward flow chamber between annular arch and the sleeve pipe, be provided with the blood suction passageway with blood backward flow chamber intercommunication in the sheathed tube lateral wall, the sheathed tube upper end is connected with the blood suction mouth with blood suction passageway circulation. Use the utility model discloses during the operation, the blood at puncture sleeve pipe position can flow into the blood backward flow intracavity along the sheathed tube outer wall, in time takes the blood that flows into the blood backward flow intracavity out through the blood suction mouth simultaneously to avoided blood further to trickle down to the endoscope lens on, thereby effectively reduced the operating time, reduced the operation risk, had good clinical result of use.
Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a puncture outfit for operation with blood holding and output function.
Background
The puncture outfit is a surgical instrument which punctures the abdominal wall and the chest wall and provides a passage for other surgical instruments to enter the body cavity, belongs to a minimally invasive surgical instrument and is used in chest and laparoscope operations.
When the existing puncture outfit is used, blood in muscular tissues at the puncture sleeve part flows downwards along the tube wall to the endoscope lens to block the operation sight, and the endoscope lens is continuously taken out to be wiped in the operation, so that the operation time is greatly prolonged, and the operation risk is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a puncture ware for operation with blood holding and output function can effectively solve the problem among the background art.
The technical scheme for realizing the purpose is as follows: the utility model provides a puncture ware for operation with blood holding and output function, includes sleeve pipe and puncture core, its characterized in that: the sleeve pipe is cylindrical and arranges perpendicularly downwards, and sheathed tube lower extreme periphery is provided with the annular of round arch, is provided with round upper end open-ended blood backward flow chamber between annular arch and the sleeve pipe, be provided with the blood suction passageway with blood backward flow chamber intercommunication in the sheathed tube lateral wall, the sheathed tube upper end is connected with the blood suction mouth with blood suction passageway circulation.
Use the utility model discloses during the operation, the blood at puncture sleeve pipe position can flow into the blood backward flow intracavity along the sheathed tube outer wall, in time takes the blood that flows into the blood backward flow intracavity out through the blood suction mouth simultaneously to avoided blood further to trickle down to the endoscope lens on, thereby effectively reduced the operating time, reduced the operation risk, had good clinical result of use.
Further, in order to facilitate puncture, the annular bulge is in a frustum shape with a downward small end.

FIG. 2 is a schematic structural view of a bushing;
fig. 3 is an enlarged view of a portion a in fig. 2.
Detailed Description
As shown in fig. 1, 2 and 3, the utility model discloses a sleeve pipe 1 and puncture core 2, sleeve pipe 1 is cylindrically, and arranges perpendicularly downwards, and sleeve pipe 1's lower extreme periphery is provided with round annular arch 4, and annular arch 4 is osculum end frustum shape down, is provided with round upper end open-ended blood backward flow chamber 5 between annular arch 4 and the sleeve pipe 1, is provided with the blood suction passageway 6 with blood backward flow chamber 5 intercommunication in the lateral wall of sleeve pipe 1, and sleeve pipe 1's upper end is connected with the blood suction mouth 7 with the circulation of blood suction passageway 6.
Use the utility model discloses during the operation, the blood at puncture sleeve 1 position can flow into blood backward flow chamber 5 along sleeve 1's outer wall in, in time will flow into the blood backward flow chamber 5 through blood suction mouth 7 simultaneously and take out to avoided blood further to trickle down on the endoscope lens.
