Sealing connector and system for intraoperative irrigation of ileus patients

Abstract

The purpose of this invention is to disclose a sealing connector and system for intraoperative enema in patients with intestinal obstruction, including an intestinal wall clamping member and a locking member. The outer contour of the intestinal wall clamping member is cylindrical, and the intestinal wall clamping member is provided with a conical hollow part and a wedge-shaped cavity around the conical hollow part. The wide head side of the wedge-shaped cavity has a first clamping part and a second clamping part. The top of the first clamping part is convex, and the second clamping part is concave. The locking member is a hollow structure, and the locking member has a conical part corresponding to the conical hollow part. The locking member also has a cylindrical part. When the top of the conical part is screwed to exceed the top of the conical hollow part, the intestinal wall is clamped between the convex and concave surfaces. The technical effect is that the intestinal wall is clamped in the U-shaped space formed by the convex and concave surfaces. The clamped area of ​​the intestinal wall is large and the length is long enough to clamp it tightly and avoid leakage during flushing or suctioning of intestinal feces.

Claims

1. A closed enema system for patients with intestinal obstruction during surgery, characterized in that, It includes an irrigation bag, an irrigation tube, a first connector, a second connector, a drainage tube, and a collection bucket. Both the first and second connectors are sealed connectors used for intraoperative enemas in patients with intestinal obstruction. The first connector holds the appendix incision end, and the second connector holds the large intestine transection incision. The collection bucket is also connected to a negative pressure suction device. The sealing connector for intraoperative enema in patients with intestinal obstruction includes an intestinal wall clamping component and a locking component; The outer contour of the intestinal wall clamp is cylindrical. The intestinal wall clamp is provided with a conical hollow part and a wedge-shaped cavity around the conical hollow part. The wide head side of the wedge-shaped cavity has a first clamping part and a second clamping part. The top of the first clamping part is convex, and the second clamping part is concave. The second clamping part is longer than the first clamping part. The locking member has a hollow structure, and has a conical portion corresponding to the conical hollow portion. The locking member also has a cylindrical portion. The conical part and the conical hollow part are threaded together. When the top of the conical part is screwed to a position beyond the top of the conical hollow part, the intestinal wall is clamped in the U-shaped space between the convex and concave surfaces. The clamping force on the intestinal wall depends on the depth to which the conical part is screwed. Both the convex and concave surfaces are provided with a number of protrusions; This system is used to perform a cleansing enema on the proximal intestinal segment at the site of obstruction. The specific cleaning process is as follows: an incision is made at the appendix, and the first connector is inserted into the appendix lumen. The other end of the first connector is connected to an irrigation bag through an irrigation tube. At the same time, the lesion incision in the large intestine is clamped to the second connector, and the other end of the second connector is connected to a collection bucket through a drainage tube. By injecting the washing solution in the irrigation bag into the large intestine through the appendix end, the feces are cleaned into the collection bucket.

2. A closed enema system for patients with intestinal obstruction during surgery, characterized in that, It includes an irrigation bag, an irrigation tube, a first connector, a second connector, a drainage tube, and a collection bucket. Both the first and second connectors are sealed connectors used for intraoperative enemas in patients with intestinal obstruction. The first connector holds the appendix incision end, and the second connector holds the large intestine transection incision. The collection bucket is also connected to a negative pressure suction device. The sealing connector for intraoperative enema in patients with intestinal obstruction includes an intestinal wall clamping component and a locking component; The outer contour of the intestinal wall clamp is cylindrical. The intestinal wall clamp is provided with a conical hollow part and a wedge-shaped cavity around the conical hollow part. The narrow inner wall of the conical hollow part is provided with an annular groove. The wide head side of the wedge-shaped cavity has a first clamping part and a second clamping part. The top of the first clamping part is convex, and the second clamping part is provided with a concave surface. The second clamping part is longer than the first clamping part. The locking member has a hollow structure, and has a conical part corresponding to the conical hollow part. The locking member also has a cylindrical part. The narrow outer wall of the conical part is provided with an annular protrusion, and the height of the annular protrusion is greater than the depth of the annular groove. The conical part and the conical hollow part are connected by an annular groove and an annular protrusion. When the conical part is pushed into the conical hollow part, the annular protrusion is inserted into the annular groove and pushes the wedge-shaped cavity to compress and deform, so that the intestinal wall is clamped in the U-shaped space between the convex and concave surfaces. The clamping force on the intestinal wall depends on the depth difference between the annular protrusion and the annular groove. Both the convex and concave surfaces are provided with a number of protrusions; This system is used to perform a cleansing enema on the proximal intestinal segment at the site of obstruction. The specific cleaning process is as follows: an incision is made at the appendix, and the first connector is inserted into the appendix lumen. The other end of the first connector is connected to an irrigation bag through an irrigation tube. At the same time, the lesion incision in the large intestine is clamped to the second connector, and the other end of the second connector is connected to a collection bucket through a drainage tube. By injecting the washing solution in the irrigation bag into the large intestine through the appendix end, the feces are cleaned into the collection bucket.

3. The closed intraoperative enema system for patients with intestinal obstruction as described in claim 1 or 2, characterized in that, The diameter of the protrusion is 0.5mm-1mm.

4. The closed intraoperative enema system for patients with intestinal obstruction as described in claim 3, characterized in that, The connector is made of rigid plastic.

5. The closed intraoperative enema system for patients with intestinal obstruction as described in claim 3, characterized in that, The length of the intestinal wall clamp is 2cm-3cm.
