Abstract

An intracavity multi-channel single-hole endoscope puncture outfit is used for a puncture cannula which is fixed on an incision of a patient and the outer wall of which can be in sealing connection with the incision of the patient, a plurality of channels which are in sealing connection with the puncture cannula and are used for operating instruments to enter the cavity of the patient from the outside of the patient, and a sealing structure which is arranged at the front end of the channel and can be used for the operating instruments to pass through and can isolate the operating instrument part which is arranged in the cavity of the patient after passing through from the operating instrument part which is arranged outside the patient. In an initial state, the channel is disposed within the puncture cannula. During puncturing, the puncture core penetrates through the sealing structure of the channel to puncture the incision. The puncture cannula maintains air-tightness while the puncture core enters the patient cavity along with the puncture core entering the incision, and the channel enters the cavity along with the puncture core overturning. The device greatly improves the range of motion of operating instruments, avoids interference and collision among the instruments, reduces the dragging of the operation to the puncture cannula fixed at the incision, and keeps the air tightness of the puncture cannula at the incision.

Description

Intracavity multichannel haplopore chamber mirror puncture ware

Technical Field

The utility model relates to the technical field of laparoscopic medical instruments, in particular to an intracavity multi-channel single-hole endoscope puncture outfit.

Technical Field

The defects of the existing single-port laparoscope puncture outfit are mainly divided into the specific defects of the single-port laparoscope puncture outfit and the common defects of the laparoscope puncture outfit, which respectively cause that the operation instrument can not form an operation triangle and the air tightness is poor. The existing single-port laparoscope puncture outfit is an external channel, namely a plurality of channels are positioned at the tail end of the single-port laparoscope puncture outfit. When the operating instrument is used, the operating instrument sequentially passes through the channel, the incision and the body, namely a plurality of operating instruments share one small incision as a supporting point, so that the operating instruments are parallel to each other, the operating instruments are often positioned on a parallel line with the lens, a chopstick effect occurs, and the 'triangle operating principle' of the laparoscope is seriously violated. The diameter of the existing laparoscope puncture outfit is fixed, and the incision size is completely based on the experience of an operator, so that the laparoscope puncture outfit and the incision are difficult to be completely matched, and the laparoscope puncture outfit and the incision are easy to leak air. In addition, the channel is fixedly connected with the laparoscopic puncture outfit, the channel is dragged during operation, and the puncture outfit is necessarily dragged at the same time, so that the air tightness between the puncture outfit and the incision is further reduced.

Further, the sealing structure is a valve structure.

Further, the number of the passages is at least two, and the inner diameter of at least one passage and the opening of the sealing structure are matched with the size of the conical puncture core.

Further, the diameter of the channel is 3-12 mm.

Further, the puncture cannula comprises a fixed part which is conveniently fixed on the incision of the patient and a movable part which can be overturned from the inside of the fixed part and extend into the cavity of the patient, the movable part is connected with the fixed part in a sealing mode, the fixed part has certain hardness and can be supported in the incision of the patient, the movable part is made of flexible materials, and the channel is connected with the movable part in a sealing mode. Therefore, the mobility and the stability of the device can be greatly improved, and in the manufacturing process, the material of the channel and the material of the movable part can be different, so that various requirements are met.

Further, the movable portion is movably coupled to the fixed portion such that the movable portion is rotatable 360 degrees about the fixed portion. Therefore, in the operation process, the position relation of each operation instrument in the cavity can be conveniently changed, the phenomena of knotting and the like of the operation instruments are prevented, and the mobility of the operation instruments is further improved.

To sum up, the utility model discloses a built-in passageway, a plurality of passageway positions extend to the patient intracavity when the operation promptly. The operation instruments sequentially pass through the incision, the channel and the cavity, each operation instrument has an independent channel as a supporting point, and the movement of the operation instruments is not limited. All the operation instruments directly enter the multiple channels in the cavity, the multiple channels become support points of the operation instruments, and the support points and the operation space are simultaneously positioned in the cavity, so that interference and collision among the instruments are avoided. The operating instrument can form an effective 'operating triangle' and follow the 'triangle operating principle' of the laparoscope. The puncture sleeve pipe improvement is that the appearance is inverted circular truncated cone shape and outer wall screw thread form arch, screws up the puncture sleeve pipe and makes the puncture sleeve pipe rise to fill whole incision and reach fixed effect, adjusts puncture sheathed tube degree of screwing up according to the incision size, reaches puncture ware and incision and closely laminates and be difficult for the slippage. In addition, the channel and the puncture outfit are respectively positioned in the cavity and the incision and are not on the same plane, and the channel and the puncture outfit are elastically connected, so that the puncture outfit is not dragged during operation, and the air tightness of the puncture outfit and the incision is not influenced.
