Description

Multifunctional gastrointestinal surgical instrument

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a multifunctional gastrointestinal surgical instrument.

Background

With the acceleration of modern life rhythm and the improvement of life pressure, more and more people are easy to have gastrointestinal discomfort. Gastrointestinal surgery is required to achieve the purpose of treatment when gastrointestinal lesions are severe.

In the clinical surgery for performing gastrointestinal surgery, a stapler is generally used to perform gastrointestinal anastomosis to facilitate the surgical operation. The selection of the type of the anastomat depends on the diameter of the intestinal canal, and if the type is not used properly, serious complications or death of pathogenic people such as gastrointestinal anastomosis failure, anastomotic leakage, anastomotic stenosis and the like can be caused. The anastomotic stenosis is a common complication after rectal surgery, and the incidence rate of anastomotic stenosis can be greatly reduced by measuring and expanding the anastomotic stenosis in an early stage. The conventional device for measuring the diameter of the intestinal canal is a fixed diameter model generally, cannot be completely suitable for all intestinal canals, cannot visually sense the expansion degree of an anastomotic stoma, and has certain limitation.

For a patient suffering from gastrointestinal obstruction, in order to increase the probability of primary anastomosis and the safety of anastomosis, gastrointestinal lavage needs to be performed in an operation, gastrointestinal contents need to be exposed in the lavage process, and the abdominal cavity is easily polluted.

In addition, stoma stenosis or retraction is a common postoperative complication for fistulization patients, and accurate measurement and matching of the intestinal canal and stoma passage during surgery can reduce the occurrence of the complication. Because the intestinal canal and the abdominal wall have certain elasticity and contractibility, how to accurately judge the diameter of the intestinal canal and how to establish a stoma passage with a proper size still have certain challenges for low-age doctors. Simultaneously, the anus endoscope microsurgery and get the sample operation through the natural chamber way all need support the anal canal, and the present commonly used supporting instrument aperture is more single and bigger partially, can not adjust according to the patient's condition is nimble, causes patient's anal canal damage easily when business turn over intestinal canal.

In conclusion, a multifunctional instrument for gastrointestinal surgery, which can solve the above problems at the same time, may bring great clinical benefit and economic benefit to patients.

When the rectum anastomosis is expanded, the multifunctional gastrointestinal surgical instrument is pulled out after the pushing handle 5 is fixed on the central rod 4 for a period of time. The rectum anastomotic stoma is repeatedly contracted and expanded in the way, thereby achieving the purpose of expanding the rectum anastomotic stoma. The method can also be used for measuring and expanding the stoma channel in the operation and can also be used for expanding the stoma of a patient with postoperative stoma stenosis.

Example 2

The multifunctional gastrointestinal surgical instrument provided by the embodiment of the application is used as an auxiliary instrument for a transanal operation. The support frame 1 and the telescopic frame 6 are connected with the pushing handle 5, and after the pushing handle 5 slides into the central rod 4, the support frame 1 in a contraction state is placed in the rectal cavity to a certain depth. Holding central pole 4, impel handle 5 to support frame 1 direction and impel gradually to make expansion bracket 6 expand, and then make support frame 1 expand, reach the purpose of strutting the intestines tube. When the intestinal canal expands to a certain extent, the pushing of the push handle 5 is stopped. A fixed anvil 11 is inserted inside the undulating teeth 10 to fix the position of the propulsion handle 5 on the central rod 4. According to the operation area of the rectum, the support frame 1 is rotated to a proper position by rotating the pushing handle 5, and then the operation area is positioned between the support rods. The air bag 3 is inflated by an external inflating device, so that the membrane cloth 2 is expanded to fix the support frame 1. The fixed cutting board 11 is pulled out, the telescopic frame 6 is contracted and the propulsion measuring device 02 is removed. The light source inside the support frame 1 is turned on, and the membrane cloth 2 is cut off to expose the operation area, thereby facilitating the operation. After the operation is finished, the air in the air bag 3 is released, and the support frame 1 is pulled out. The method can also be used for taking out the pathological tissues in the NOSES operation, and avoids the damage of a rigid surgical instrument with a single diameter to the anal canal when the rigid surgical instrument enters and exits the intestinal canal.

Example 3

The multifunctional gastrointestinal surgical instrument provided by the embodiment of the application is used for gastrointestinal lavage. A pouch with proper size is sewn on the side wall of the intestine pipe at the decompression end according to requirements. The support frame 1 and the telescopic frame 6 are connected with the pushing handle 5, and after the pushing handle 5 slides into the central rod 4, the support frame 1 in a contraction state is placed in a purse-string range. Holding central pole 4, impel handle 5 to support frame 1 direction and impel gradually to make expansion bracket 6 expand, and then make support frame 1 expand, reach the purpose of strutting the intestines tube. After the intestine is expanded to a certain extent, the propulsion is stopped, and the fixed cutting board 11 is inserted into the wavy saw tooth 10 to fix the position of the propulsion handle 5 on the central rod 4. The air bag 3 is inflated by an external inflating device, so that the membrane cloth 2 is expanded to fix the support frame 1. A purse string thread is fixed at the far end of the air sac 3, so that the intestinal canal is hermetically connected with the end part of the support frame 1. The air bag 3 is continuously inflated to maintain the support frame 1 in the expanded state. The propulsion measuring device 02 is removed, the intestinal wall is opened in the support frame 1, the decompression drainage bag is fixed at the near end of the other air bag 3, so that intestinal contents can be drained into the decompression bag, and the risk of leakage of the intestinal contents into the abdominal cavity is reduced.

Another support 1 may be used as a connection means for irrigation. Specifically, the appendix is incised, the stent 1 in its contracted state is inserted into the colon through the lumen of the appendix, and the two balloons 3 are inflated to maintain the stent 1 in its expanded state. The other end of the support frame 1 is inserted into a water inlet pipeline, and lavage liquid can be injected into the intestinal canal through the support frame 1, so that the purpose of lavage of the intestinal canal is achieved.

The size that the multi-functional stomach intestine surgical instrument that this application embodiment provided can adjust the support frame in a flexible way under the operator's control dynamics, regardless of several fixed diameter models, reduces the injury to the intestines tube. Can adjust the contraction state of support frame 1 through propulsion handle 5, avoid rigid support frame 1 to advance out the damage of intestines tube to intestines tube, and shrink scope is big, easily control.
