Description

Special multifunctional channel for laparoscopic surgery tubular anastomat

The technical field is as follows:

the invention relates to a surgical instrument, in particular to a multifunctional channel special for a laparoscopic surgery tubular anastomat.

Background art:

the safety and reliability of the tubular anastomat in the reconstruction of the digestive tract enable the tubular anastomat to be widely applied to open surgery. However, in laparoscopic surgery, particularly reconstruction after removal of a tumor at the gastroesophageal junction, anastomosis of the esophagus with the jejunum or the remnant stomach can only be accomplished in vivo due to anatomical reasons, which requires a sufficiently large passage for the insertion of the anvil and stapler body when the reconstruction of the digestive tract is completed. Since the working channel for the free resection can pass only an instrument having a maximum diameter of 15mm, and the minimum diameter of the tube-type anastomat for the reconstruction of the digestive tract is 21mm, the reconstruction of the digestive tract is completed by enlarging the incision and establishing a larger channel. The current solution is to enlarge the incision after one trocar is pulled out (which trocar is determined by the preference of the operator), put in an incision retraction protective sleeve, pull the jejunum (the diameter of the residual stomach is not required to be determined before anastomosis, generally 25 is selected), determine the diameter type of the selected anastomat and put in a corresponding anvil. Then, the tail end of one finger stall is cut off by a medical glove to open the finger stall, the pulled trocar is bundled and sealed through the opened finger stall and silk threads, the glove is connected with the incision retraction protective sleeve and sealed, pneumoperitoneum is reconstructed, the nail anvil is placed into the esophagus and disconnected and closed under direct vision, the glove is taken down to remove the pneumoperitoneum, and the specimen is taken out. And then cutting off one finger sleeve of the glove, penetrating the anastomat through the finger sleeve (because the diameter of the finger of the medical glove is not more than 15mm, the anastomat can naturally ensure the airtight state between the finger sleeve and the finger sleeve due to elastic retraction after penetrating through the finger sleeve), then connecting the glove with the incision retraction protective sleeve again to be airtight, reconstructing pneumoperitoneum, sleeving the jejunum or the residual stomach into the anastomat under a mirror, completing reconstruction, withdrawing the anastomat after completing reconstruction, and closing the finger sleeve opening through clamping or ligation. And after the pneumoperitoneum is reestablished again, the subsequent work is completed. The pneumoperitoneum status was terminated and reestablished a minimum of 2 times during the above procedure. The procedure is complicated and the technical requirement is high, and a new operation channel is designed to solve the problem.

The invention content is as follows:

the invention aims to overcome the defects in the prior art and provides a special multifunctional channel for a laparoscopic surgery tubular anastomat.

The application provides the following technical scheme:

the utility model provides a special multi-functional passageway of laparoscopic surgery cast anastomat, it includes the base, is equipped with a set of passageway pipe on the base, still connects at least one pneumoperitoneum machine interface on base upper portion, still is equipped with a cavity in the base lower part, is equipped with the joint ring of being connected with the cooperation of incision protector in the cavity, its characterized in that: the upper end of one of the channel tubes is provided with a connector, a sealing film is arranged in the connector, the sealing film is provided with a through hole, the connector is detachably connected with a sealing valve, the base is connected with a pull rope, and the pull rope is connected with a sealing clamp which forms corresponding fit with one of the channel tubes.

On the basis of the technical scheme, the following further technical scheme can be provided:

the sealing valve comprises a shell, an upper sealing ring is arranged in the shell, a group of lower sealing valve plates are connected to the upper sealing ring, a middle sealing ring is connected to the lower sealing valve plates, a group of protection plates are connected to the middle sealing ring, and the upper sealing ring is connected to the protection plates.

The base and the channel pipe are made of elastomer materials, and the shell and the connector are made of hard medical polymer materials.

The sealing valve is in threaded connection with the connector.

The group of channel pipes comprise at least two diameters, and the connecting head is arranged at the upper end of the channel pipe with the largest diameter.

The invention has the advantages that:

the invention is used together with an incision retractor protector, is arranged at an auxiliary incision, is dissociated, separates a sealing valve from a channel connector, and is switched to a channel state for anastomosis. After the intestinal canal or the remnant stomach is pre-anastomosed through in vitro treatment, the anastomat is connected with the intestinal canal or the remnant stomach through the channel, the channel is connected with the incision retraction protector, pneumoperitoneum is reconstructed, and the digestive tract reconstruction is completed under direct vision. And then, withdrawing the anastomat from the channel, clamping the channel by using the clamping device, and continuously finishing the subsequent operation. The channel can freely switch the channels with two diameters required by resection and reconstruction, and can maintain pneumoperitoneum state during switching.

And the channel can freely pass through the anastomat, and the anastomat body cannot pass through the channel like a finger sleeve of an artificial expansion glove when a medical glove is used.

The channel and incision retractor protector is a matched product, sufficient strength and airtightness are considered during design, and the fact that gloves need to be replaced due to the fact that the gloves cannot bear pneumoperitoneum pressure due to the fact that the gloves cannot have the strength and are severely expanded when medical gloves are used or the fact that an extra vascular clamp is needed to tighten up the edges of the gloves when the gloves are connected with the gloves, and the gloves are separated from the incision protector under the pneumoperitoneum action again is avoided.

The most obvious advantage of the channel is that the anastomat can freely and relatively shift relative to the channel when the executing device body and the nail anvil are in butt joint, triggering and anastomosis links, so that the flexibility of the anastomat is ensured, and the anastomosis quality is ensured. When the medical gloves are used for completing anastomosis, because the gloves and the anastomat cannot slide smoothly, the anastomosis is completed by using a large force to resist pneumoperitoneum when the medical gloves enter the anastomat body, and the anastomosis is completed by keeping the large force to prevent tissues at the anastomosis opening from being torn due to the sudden outward movement of the anastomat under the pressure of the pneumoperitoneum, so that the anastomosis failure is caused.

After anastomosis is finished, the anastomat can be freely withdrawn, before the anastomat is withdrawn, a clamping device (sealing clamp) is arranged at the root of the channel, the tightness of the pneumoperitoneum can be ensured, and the operation can be finished by one person in the process. The medical gloves can be completed only by the joint operation of an operator and an assistant because the body and the gloves are tightly combined.
