Description

Anastomat guiding device

Technical Field

The utility model relates to an anastomat guiding device in the technical field of medical instruments.

Background

In the complete laparoscopic gastrectomy, the anastomosis of the esophagus and the jejunum is a difficult operation. At present, although there are various esophageal jejunum anastomosis modes, the various modes have respective advantages and disadvantages, and no standard mode exists. Although the Overlap anastomosis method is proposed in recent years, the Overlap anastomosis method is better applied at present due to the characteristics of high anastomosis safety, convenience in operation and the like.

In the Overlap anastomosis method, a small hole is formed in the left side of the broken end of the esophagus, a 60mm linear anastomat is placed into a 12mm Trocar on the left side of an operator, a nail surface is inserted into jejunum, a non-nail surface is inserted into a small opening of the esophagus, and esophageal jejunum lateral anastomosis is performed. However, when the non-nail surface of the linear anastomat is inserted into the esophageal laceration, a 'false cavity' may be inserted into the esophageal wall, wherein the esophageal wall has 4 layers, namely, a mucous membrane layer, a submucosal layer, a muscular layer and an adventitial layer. To reduce the risk of such insertion into a "false lumen," the clinician would use a gastric tube inserted through the mouth to the esophageal stump to guide the stapler into the esophageal mucosa cavity. However, the front end of the stomach tube in clinic is circular, the front end of the non-nail surface of the anastomat is arc-shaped, the shapes of the stomach tube and the anastomat are different, and the butt joint relation cannot be formed, so that the risk of inserting the 'false cavity' cannot be completely eradicated. This potential "false lumen" risk limits the use of Overlap to some extent. Simultaneously, because the esophagus opening is less in order to prevent the emergence of postoperative anastomotic fistula, increased the non-nail face of anastomat and got into the degree of difficulty of esophagus, lead to many doctors to need to try many times just can get into the esophagus, and the esophagus is destroyed because of the gastrectomy, the blood supply is relatively poor, originally, there is the risk that the healing is bad and take place anastomotic fistula, the non-nail face of recurrent anastomat inserts the failure and has caused more injuries to the esophagus, the risk that postoperative anastomotic fistula leaks has increased, the anastomosis time has been prolonged simultaneously, the anesthesiologist need still to insert the stomach tube repeatedly in order to assist the art person.

Referring to fig. 1 to 3, an anastomat guide device in an embodiment of the present invention includes an anastomat sleeve 300 and a flexible guide tube 200, the anastomat sleeve 300 is fixed at an end of the guide tube 200, specifically, the guide tube 200 has a first end and a second end, and the anastomat sleeve 300 is fixed at the second end of the guide tube 200. The stapler includes interfitting staple face section 401 and non-staple face section 400, and the stapler sleeve 300 is used to secure the non-staple face section 400 of the stapler. Specifically, the fluid channel 301 has an arcuate cross-section, and the end of the fluid channel 301 distal to the guide tube 200 is used for insertion of the non-staple section 400 of the stapler. The cross-sectional dimensions of the fluid channel 301 match the dimensions of the stapler non-staple face segment 400 so that the stapler non-staple face segment can be inserted into the stapler sheath 300 and secured. The material of the anastomat sleeve 300 is the same as that of the stomach tube, so that the difficulty of the guide tube 200 entering the esophagus cannot be increased, and the extra injury to a patient cannot be caused. In this embodiment, the stapler sleeve 300 can accommodate the 1/5 length of the front end of the stapler non-staple face section 400, so that a certain stress area is formed between the stapler sleeve 300 and the stapler non-staple face section 400, an operator can conveniently insert the stapler non-staple face section 400 into the esophagus cavity correctly by pushing the stapler sleeve 300, the operation is simple and convenient, the accuracy is high, the success rate of inserting into the esophagus once is improved, and the injury to the esophagus caused by repeated insertion due to misoperation is avoided.

Alternatively, the length of the guide tube 200 is greater than that of the esophagus so that the guide tube 200 can pass through the side opening of the esophagus, and the operator can know the position of the opening of the esophagus through the guide tube 200 under the laparoscopic view, thereby correctly inserting the stapler; in addition, the guiding tube 200 is ensured to be partially remained and out of the body all the time, which is convenient for the medical staff to operate. The anastomat and the anastomat guiding device are stretched into the body of a patient, medical staff can send the anastomat to the corresponding position of the esophagus by controlling the guiding tube 200 outside the body, and when the non-nail surface section 400 of the anastomat reaches the corresponding position, the guiding tube 200 is pulled outwards to separate the anastomat sleeve 300 from the non-nail surface section 400 of the anastomat, so that the placement and the positioning of the non-nail surface section 400 of the anastomat are completed. Further, scales are arranged on the outer side surface of the guide tube 200 along the length direction, so that an operator can accurately control the insertion depth of the guide tube 200.

The stapler cover 300 has a fluid passage 301, the fluid passage 301 communicates with the guide tube 200, and the first end of the guide tube 200 is provided with the injection connector 101. The syringe is connected to the guide tube 200 through the injection connector 101, and liquid can be injected into the esophagus through the guide tube 200 and the stapler cover 300. After the esophagus-jejunum anastomosis is finished, a small amount of blue beauty can be injected to the bottom of the esophagus through the guide tube 200 by the injection joint 101 to judge whether the anastomosis is complete or not and whether residual leakage exists or not, so that serious consequences caused by the anastomosis leakage after a postoperative patient eats are avoided. Further, a detachable plugging cap 100 is further disposed on the injection connector 101, and the plugging cap 100 is used for plugging the injection connector 101. When the injection is not needed, the injection connector 101 is blocked by the blocking cap 100, so that air or other foreign matters are prevented from entering the esophagus through the guide tube 200 to influence the health of a patient; to inject, the injection fitting 101 is reopened to complete the injection. To prevent the blocking cap 100 from being lost, the blocking cap 100 is mounted at the side of the injection connector 101 by a bendable connecting band.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
