Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1 to 3, the multi-channel single-port laparoscopic surgical puncture outfit of the present invention comprises: the multi-channel operation platform comprises a multi-channel operation platform 1 and an incision protection sleeve 2 connected with the multi-channel operation platform 1. The multi-channel operation platform 1 comprises: the protective sheath secures the ring 15. Referring to fig. 3, the incision protection cover 2 includes: an outer ring 21, a channel 22, and an insert ring 23, the channel 22 connecting the outer ring 21 and the insert ring 23. The diameter of the insert ring 23 is larger than the diameter of the outer ring 21. The outer ring 21 is sleeved on the protective sleeve fixing ring 15, so that the connection between the multi-channel operating platform 1 and the incision protective sleeve 2 is realized.

The multi-channel operation platform 1 further comprises: a porous cover 14, a plurality of instrument channels 11 fixed on the porous cover 14, an air inlet pipe 12 and an air outlet pipe 13. A protective sheath retaining ring 15 is attached to the bottom of the porous cap 14.

During operation, a small incision is made on the abdomen, the insertion ring 23 of the incision protection sleeve 2 is inserted into the abdominal cavity after being extruded and deformed, and the outer ring 21 is left outside the abdominal cavity. The channels 22 are membrane channels. The channel 22 can be a film made of Thermoplastic Polyurethane (TPU) material, has high modulus, high strength, high elongation and high elasticity, is an environment-friendly raw material, and has the advantages of no toxicity, good processability and excellent rebound resilience. The outer ring 21 and the insert ring 23 may alternatively be made of thermoplastic polyurethane. The outer ring 21 and the insert ring 23 are connected by a channel 22, the channel 22 being cylindrical after inflation. After the insertion ring 23 is inserted into the abdominal cavity, the outer ring 21 remaining outside the abdominal cavity is continuously turned down, so that the distance between the outer ring 21 and the insertion ring 23 can be gradually reduced. After the outer ring 21 is fitted over the lower portion of the sheath lock ring 15, a surgical instrument can be inserted into the abdominal cavity from the instrument channel 11 through the channel 22.

The diameter of the insert ring 23 of the present invention is larger than the diameter of the outer ring 21. The diameter of the outer ring 21 cannot be made too large because the outer ring 21 needs to be fitted over the boot attachment ring 15. The diameter of the implantation ring 23 is increased, namely the aperture of the implantation ring 23 is increased, when the incision protection sleeve 2 is tightly connected with the multi-channel operation platform 1, the implantation ring 23 with the larger diameter ensures the operation margin of the surgical instrument, and meanwhile, the operation incision can be further enlarged under the condition that the length of the operation incision is not increased, so that the operation is more convenient.

Referring to FIG. 3, the diameter (D1) of the insert ring 23 is 5-15 mm larger than the diameter (D2) of the outer ring 21.

In some embodiments, the outer ring 21 has a diameter of 60mm and the placement ring 23 has a diameter of 70 mm. In other embodiments, the outer ring 21 has a diameter of 80mm and the insert ring 23 has a diameter of 90 mm. The error is not more than 5 mm.

The porous cover 14 is a circular plate having a plurality of connecting holes, and the instrument channel 11 is fixed to the plate and communicates with the connecting holes of the plate. The air inlet pipe 12 and the air outlet pipe 13 are used for establishing artificial pneumoperitoneum, so that the peritoneal wall is separated from visceral organs, the abdominal cavity is enlarged to facilitate the operation, and the damage to the organs is avoided when the trocar is punctured into the abdominal cavity. Pneumoperitoneum is the key to the success of laparoscopic surgery. The gas enters or exits the abdominal cavity through the gas inlet pipe 12, the gas outlet pipe 13 and the passage 22. The air inlet pipe 12 and the air outlet pipe 13 are silicone tubes.

The protective sheath retainer ring 15 may be connected to the porous cap 14 by a snap 16. For example, the buckle 16 may be designed as a ring-shaped connector having a circular groove on the periphery thereof, the protective sleeve fixing ring 15 and the porous cover 14 have certain elasticity, and the lower portion of the porous cover 14 and the upper portion of the protective sleeve fixing ring 15 are respectively embedded into the groove of the buckle 16, so as to achieve connection therebetween. The bottom of the protective sleeve fixing ring 15 is in a ring shape, and the outer ring 21 of the incision protective sleeve 2 can be sleeved on the protective sleeve fixing ring 15.

The instrument channel 11 is provided with a sealing ring 111, a choke valve 112, gaskets, etc. to maintain pneumoperitoneum pressure.

In some embodiments, 4 instrument channels 11 are provided, which may be used in combination with multiple instruments at a time.

The utility model discloses a use method of multichannel haplopore laparoscopic surgery puncture ware illustrates as follows:

a small incision is made on the umbilical region of a patient, the insertion ring 23 is pushed into the abdomen through the incision after being extruded by oval forceps, and then the insertion ring 23 automatically rebounds to be circular. The incision sheath 2 is pulled up so that the insertion ring 23 catches the incision and the outer ring 21 is continuously turned inside out. Since the bottom of the outer ring 21 is connected with the film channel 22, when the outer ring is turned inside, the film channel 22 is turned inside, the length of the channel 22 is continuously reduced, and the distance between the outer ring 21 and the embedded ring 23 is reduced. After the distance is adjusted to a proper distance, the outer ring 21 is sleeved on the protective sleeve fixing ring 15 of the multi-channel operation platform 1. The physician inserts an endoscope, a separation forceps, etc. through the individual instrument channels 11 into the abdominal cavity to perform the procedure. The diameter of the implantation ring 23 is larger than that of the outer ring 21, the implantation ring 23 which covers the incision further enlarges the incision through the thin film channel 22, and meanwhile, the operation scope of the surgical instrument is ensured, and the flexibility and the convenience are better. When the operation is finished, the edge of the placing ring 23 is buckled by fingers, and the placing ring 23 is pulled outwards along the channel 22, so that the placing ring and the multi-channel operation platform 1 can be smoothly taken out.

To sum up, the utility model discloses a multichannel haplopore laparoscopic surgery puncture ware and incision protective sheath structural design are simple, convenient operation, and flexibility ratio, convenience are good.

While the present invention has been described in detail with reference to the preferred embodiments thereof, it should be understood that the above description should not be taken as limiting the present invention.
