Description

Laparoscope umbrella stapler

Technical Field

The invention belongs to the technical field of anastomats, and particularly relates to a laparoscopic umbrella-powered anastomat.

Background

At present, laparoscopic technology is widely carried out, particularly laparoscopic digestive tract tumor resection, reconstruction of hollow organs of a digestive tract is involved after tumor resection, such as laparoscopic total gastrectomy, the key problem is digestive tract reconstruction after total gastrectomy, and most surgeons choose to operate under an auxiliary incision. When operated under a laparoscope, most doctors select the straight line cutting closer for side-to-side anastomosis, and the defects are that the lower end of the esophagus needs to be kept longer, the cutting edge is limited, and the straight line cutting closer is not suitable for patients with higher esophageal resection lines. Jejunoesophageal anastomosis has also been performed by a few physicians using circular stapler methods [ peroral insertion of staple anvil devices (OrVilTM) ] which are introduced transorally and may introduce bacteria along the way to induce abdominal infections. If the orientation is incorrect, the staple anvil can be difficult to pass smoothly through the pharynx. When the stomach tube is pulled down by an operator to generate resistance, brute force can not be used, and the nail anvil can be replaced after retreating from the outlet cavity if necessary. When the nail anvil block is pulled from top to bottom in the esophagus, if improper force is applied, the mucosa of the esophagus is easily damaged, and particularly for patients with large tumors at the junction of the esophagus and the stomach, esophagus expansion and mucosa edema. There are many methods that are improved on this basis, but none of them can perform the circular stapler method directly under the laparoscope because the circular stapler is large and cannot be inserted into the abdominal cavity through the puncture hole. For example, the end-to-end anastomosis of the colorectal is performed by means of laparoscopic colorectal cancer resection instead of laparotomy after the tumor is free to be cut off, the end-to-end anastomosis of the colorectal cannot be performed under the laparoscope unless the incision is enlarged, the circular nail anvil block is sent into the incision, then the incision is closed, and finally the end-to-end anastomosis of the colorectal is performed under the laparoscope. Certainly, there are laparoscopic surgeries such as laparoscopic sigmoid colon cancer resection, laparoscopic transverse colon cancer resection, laparoscopic right-half colon resection and left-half colon resection, and after tumor resection, the abdominal operation and specimen removal are all needed, and meanwhile, the enteroenterostomy is performed by enlarging the incision, and no laparoscopic instrument is used for performing the enterostomy directly under the laparoscope.

The disadvantage of the circular anastomat for the end-to-end anastomosis is that the anastomat main body cannot enter the abdominal cavity through the trocar hole, the pneumoperitoneum needs to be closed, and the auxiliary small incision can be placed, so that the smoothness and the ornamental value of the operation are reduced. And the traditional anastomat has poor antibacterial performance, is easy to breed bacteria and is not beneficial to the health of patients.

The working principle is as follows: in order to break through the existing technical obstacles, a special circular anastomat under a special laparoscope is designed, end-to-end anastomosis and end-to-side anastomosis are easily performed, in order to pass through a puncture hole of 1.2 cm, the anastomat is designed into a linear column shape smaller than 1.2 cm and is expanded into the circular anastomat after passing through the puncture hole, a nail supporting seat 231 and a body 241 are changed into a circular shape from a straight line, when the anastomat does not enter an abdominal cavity, the space after entering the abdominal cavity is enlarged, the straight anastomat is changed into the circular anastomat, after the anastomosis is completed, the circular shape is changed into the straight line, and the puncture hole of 1.2 cm is withdrawn, so the circular anastomat;

the use principle is as follows, firstly the spring tube 21 is put into the intestinal tract through the puncture hole, then the mandrel structure 2011 is inserted into the mandrel-shaped clamping groove 210, as shown in fig. 5, the principle of changing the straight line into the circle is as follows: firstly, the handle 31 is gripped, the handle 31 rotates to drive the rectangular block 33 to rotate anticlockwise, the first nail drill rod 22 is pushed leftwards, the second nail drill rod 221 is pushed leftwards by the first nail drill rod 22, the rectangular rod 233 and the second circular ring 232 are driven to move leftwards, and the nail seat 231 is propped open under the action of the first steel bar 234, and the principle is the same as that of umbrella opening;

the first nail drill rod 22 moves leftwards to drive the first round rod 2401 and the third round ring 24 to move leftwards and drive the second round rod 2421 and the fourth round ring 242 to move leftwards, when the third round ring 24 moves leftwards, the body 241 is spread under the action of the second steel bar 244, when the fourth round ring 242 is in contact with the fifth round ring 243, the fourth round ring 242 pushes the fifth round ring 243 to move leftwards to drive the opened body 241 to move leftwards, the opened body 241 is inosculated with the opened nail abutting seat 231 to cut off, and then the anastomat is pulled out;

as shown in fig. 1, 9 and 10, the principle of changing from a circle to a straight line is as follows: the handle 31 is loosened, under the action of the torsion spring 35, the handle 31 and the rectangular block 33 are restored to the original positions, the second spring 34 pulls the first nailing drill rod 22 to the right to the original positions, and the nail abutting seats 231 can be folded by pressing inwards;

the first nailing rod 22 moves rightwards to drive the first round rod 2401 and the third round ring 24 to move rightwards, and simultaneously drive the second round rod 2421 and the fourth round ring 242 to move rightwards, when the third round ring 24 moves rightwards, the body 241 is folded under the action of the second steel bar 244, and the fifth round ring 243 is pushed back to the original position by the first spring 245.

The scheme has the following advantages:

1. the circular anastomosis method under the complete laparoscope is completely the same as the laparotomy operation. 2. The relatively high-difficulty operation is carried out, the space is narrow and small, the fat patient needs to cut off enough incisal margins, the narrow space of a puncture hole of the laparoscope is broken through by means of the advantage of laparotomy circular anastomosis, circular anastomosis under the laparoscope is realized, and the laparoscope umbrella anastomat has the maximum advantage. 3. The abdominal wound is minimally invasive, the anastomosis of the laparoscopic umbrella anastomat under the same condition is less invasive than that of any one conventional anastomosis method, and the side injury of other anastomosis methods is avoided. 4. The operation time is shortened. 5. The human intestinal tract is linear, and only one end of the human intestinal tract is in butt joint with the other end of the human intestinal tract to restore the original physiological shape. 6. Through the action of the antibacterial layer, the antibacterial effect is greatly improved, the patient is effectively prevented from being infected by bacteria, and the recovery of the patient is facilitated.
