Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laparoscope negative pressure flushing and drainage device. Background Art

[0002] Entering the 21st century, minimally invasive surgery represented by laparoscopic technology has become an important direction of medical development. Most abdominal organ surgeries can be completed under laparoscopy. Before the end of the operation, a peritoneal drainage tube will be placed at the site of potential infection risk. Close observation after the operation. Normal drainage fluid is light bloody or light yellow ascites with good fluidity. If the drainage fluid is found to be turbid, viscous, gray-yellow, brown, and has increased residue or flocs, it indicates that surgical wound infection may occur. If the drainage fluid is obviously bile, pancreatic juice, gastric juice or feces , it is undoubtedly a digestive tract fistula. Due to the small diameter of the tube, it is easy to get blocked. After the blockage, the infectious body fluid will be retained, forming local necrosis and abscesses. The infected substances will corrode and aggravate the digestive tract fistula. At this time, the drainage tube should be flushed and unblocked in time. However, since fistula and infection often occur about a week after the operation, the sinus around the drainage tube has not yet formed, and the original drainage tube cannot be removed and placed for double-tube flushing. Therefore, it is necessary to flush on the original basis. Double-tube flushing is water inlet in the outer tube and suction in the inner tube. In order to utilize the channel of the original drainage tube, the structure of the double-tube needs to be changed. , cut a side hole on the drainage tube, insert the inner cannula into the side hole to let water in, the original drainage tube becomes the outer tube for suction, the water flow of the inner cannula flushes the flocs in the drainage tube outward, restores the patency of the drainage tube, and then connects the inner cannula and the tail of the drainage tube to the infusion set and the suction device respectively to achieve continuous flushing of the abdominal drainage tube. However, in the actual operation, the connection between the pipelines and the suction device is plug-in, which is fixed by friction. The connection is relatively unstable, and the pipeline connection will become loose, resulting in the appearance of The leakage causes the patient's dressings, sheets, and clothes to be soaked. At the same time, some necrotic blocks will flow out during flushing, and the suction tube is easily blocked by these tissue objects. The common blockage location is the joint connected to the drainage tube. Some necrotic blocks will be stuck at the joint, resulting in the failure of the subsequent water flow to be sucked away in time, and leaking out from the side holes or around the tube. The traditional treatment method is to unplug the joint, pull out the blocked necrotic matter, and then reconnect the joint. This method is more troublesome, and the accumulated fluid will spill out during cleaning, causing pollution. Utility Model Content

[0023] The laparoscopic negative pressure flushing and drainage device is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 1

[0026] See also Figure 1-6 In the present embodiment, a laparoscopic negative pressure flushing and drainage device is provided, comprising: an outer tube 1, one end of the outer tube 1 is fixedly connected with a connector 11, one end of the connector 11 is threadedly connected with a connector 12, the bottom end of the connector 12 is fixedly connected with a drainage tube 13, the bottom end of the drainage tube 13 is provided with a negative pressure barrel 14, the top of the negative pressure barrel 14 is provided with a connecting seat 15, a dredging component, the dredging component is arranged inside the connector 12, and is used to dredge the connector 12, and a connecting component, the connecting component is arranged on the connecting seat 15, and is used to be connected to the drainage tube 13.

[0027] Among them, by setting the dredging component, the connection between the connector 11 and the connector 12 can be dredged without disassembling the two, and the blocked necrotic objects can be pulled out, avoiding the spillage of accumulated liquid during cleaning and causing pollution, which is simpler, more convenient, and saves time and effort;

[0028] Secondly, through the setting of the connecting component, the drainage tube 13 can be connected and fixed, and the stability of the connection can be enhanced to prevent the connection between the drainage tube 13 and the negative pressure barrel 14 from loosening, resulting in water leakage around the tube, causing the patient's dressings, sheets, and clothes to be soaked. The connection is simple, quick and highly tight.

[0029] Example 2

[0030] On the basis of Example 1, the clearing component includes: a through hole opened at the end of the connecting piece 12 away from the connecting head 11, a liquid sealing ring 2 is provided inside the through hole, a rotating rod 21 is rotatably connected inside the liquid sealing ring 2, one end of the rotating rod 21 extends to the inside of the connecting head 11, a spiral blade 22 is provided on the outside of the rotating rod 21, there is a gap between the outside of the spiral blade 22 and the inner cavity of the connecting piece 12 for allowing human tissue to flow out, and a rotating handle 23 is fixedly connected to the end of the rotating rod 21 away from the connecting head 11.

[0031] During flushing, some human body components will be stuck at the connection position between the connector 11 and the connector 12, and some block-shaped necrotic matter will be stuck at the joint position, causing the water flow behind to be unable to be sucked away in time, and leaking out from the side holes or around the tube. At this time, the person will rotate the handle 23 to rotate the rotating rod 21, and the rotating rod 21 drives the external spiral blade 22 to rotate. When the spiral blade 22 rotates, the block-shaped necrotic matter will be crushed and moved to one side. The crushed block will be sucked into the negative pressure barrel 14 along the drainage tube 13, and will be dredged by the forward and reverse rotation of the spiral blade 22. Sufficient gap space is reserved between the outside of the spiral blade 22 and the connector 12, and some small blocks will flow out directly along the gap.

[0032] Example 3

[0033] On the basis of Example 1, the connecting component includes: a socket 3 in an octagonal structure connected to the top of the connecting seat 15, the socket 3 is provided with four sliding holes 31 distributed in a ring array, the four sliding holes 31 are slidably connected to the inside of each of the four sliding holes 31, and the ends of the four sliding holes 31 facing the inside are arranged in an arc shape suitable for the ball 32, a plug connector 33 connected to the bottom end of the drainage tube 13, the bottom end of the plug connector 33 is plugged into the socket 3, and the plug connector 33 is provided with a clamping hole 34 arranged to match the ball 32.

[0034] During actual operation, the pipeline connection may be loose and water may leak around the pipe, causing the patient's dressings, sheets, and clothes to get wet. When connecting the drainage tube 13 to the negative pressure barrel 14, the plug connector 33 at the bottom of the drainage tube 13 is inserted into the socket 3. When inserting, ensure that the clamping hole 34 is relatively aligned with the sliding hole 31. After fully inserted, the clamping hole 34 is aligned with the sliding hole 31, and the ball 32 slides inside the sliding hole 31 toward one end of the clamping hole 34 and is clamped in. One end of the sliding hole 31 is set in an arc shape suitable for the ball 32, thereby preventing the ball 32 from sliding out from this end, and a part of the ball 32 will be exposed just enough to clamp the clamping hole 34, so as to fix the drainage tube 13 and prevent the connection between the drainage tube 13 and the negative pressure barrel 14 from loosening and leaking.

[0035] Among them, a limiting ring 35 is fixedly connected to the top of the socket 3, a retaining ring 36 is fixedly connected to the outside of the plug connector 33 near the top position, a matching sliding sleeve 37 is slidably connected to the outside of the socket 3, a baffle 38 used in conjunction with four balls 32 is fixedly connected to the inner wall of the sliding sleeve 37, and push blocks 39 are fixedly connected to the tops of the four baffles 38. A fixed tube 310 is provided on the outside of the socket 3, and a storage cavity can be formed between the fixed tube 310 and the socket 3. The sliding sleeve 37 is slidably connected to the inside of the storage cavity, and a spring 311 is connected between the bottom end of the sliding sleeve 37 and the bottom of the storage cavity.

[0036] The four baffles 38 on the inner wall of the sliding sleeve 37 are located on one side of the four sliding holes 31, thereby blocking the ball 32 and preventing the ball 32 from sliding inside the sliding hole 31, so that the ball 32 is always at the other end of the sliding hole 31. When the drainage tube 13 is connected to the socket 3, the sliding sleeve 37 is pulled downward, and the sliding sleeve 37 moves downward, so that the four baffles 38 are moved away from the positions of the four sliding holes 31, and the sliding sleeve 37 slides into the storage cavity formed between the fixed tube 310 and the socket 3. At the same time, the spring 311 is squeezed and contracted to store energy. Since the baffle 38 is moved away from one side of the sliding hole 31, the ball 32 can slide inside the sliding hole 31, and the plug connector 33 is inserted into the plug connector 3 and is in contact with the ball The retaining ring 36 can limit the insertion depth of the plug connector 33, so that after the plug connector 33 is inserted, the clamping hole 34 is just flush with the sliding hole 31. After the plug connector 33 is inserted, the sliding sleeve 37 is released, and the spring 311 releases its elasticity to push the sliding sleeve 37 upward. Under the action of the pushing block 39 at the top of the baffle 38, the ball 32 will move into the sliding hole 31 until it completely enters the sliding hole 31. The limiting ring 35 can limit the sliding sleeve 37, so that the baffle 38 is just parallel to the position of the sliding hole 31 when it moves upward, so as to connect and fix the drainage tube 13.

[0037] Among them, an inner tube 16 is provided inside the outer tube 1, and a water inlet 17 is fixedly connected to the connecting head 11. The water inlet 17 is communicated with the inner tube 16. The inner tube 16 is arranged inside the outer tube 1, which avoids the trouble of cutting a hole in the outer tube 1 to insert the inner tube 16 during subsequent flushing, and prevents the problem of accumulated fluid flowing out from the cut opening. During flushing, the infusion set can be directly connected to the water inlet 17. Under normal circumstances, the water inlet 17 is sealed.
