Description

Technical Field

[0001] This disclosure relates to the field of laparoscopic surgery technology, and in particular to an automated device for simultaneously traction of the liver and stomach during laparoscopic pancreatic surgery and its method of use. Background Technology

[0002] The pancreas is located deep within the body, below the liver and behind the stomach, and is a retroperitoneal organ. Due to its deep location, difficulty in exposure, and proximity to major blood vessels and vital organs, pancreatic surgery has long been considered a forbidden area in surgery. Because of the unique nature of pancreatic tissue, postoperative complications are frequent and severe, and improper management can be life-threatening. Over the past 20 years, with the popularization of minimally invasive concepts and the development of laparoscopic techniques, an increasing number of benign and malignant pancreatic tumors are being treated laparoscopically or robotically. Due to the complexity of the procedure, most laparoscopic pancreatic surgeries are performed only in large medical centers.

[0003] The pancreas is located deep within the body, and laparoscopic pancreatic surgery often requires retraction of the liver and stomach to expose the pancreas for easier surgical manipulation. However, current retraction methods are often time-consuming and laborious, prone to causing collateral liver damage, and have poor retraction effectiveness, resulting in inadequate surgical field exposure and often leading to surgical complications. In some cases, the inability to accurately expose the pancreas may necessitate conversion to open surgery. Proper retraction of the liver and stomach to fully expose the pancreas frees the surgeon's hands, allowing them to focus on precise tumor resection and subsequent reconstruction. Therefore, there is a lack of devices on the market that can simultaneously retract the liver and stomach during laparoscopic pancreatic surgery to facilitate surgical field exposure.

[0058] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0059] The dimensions and sizes of the various structural components of the traction automation device in this solution can be adjusted according to the patient's body shape. This application does not limit the traction automation device; as long as it can be used for surgical assistance in accordance with the structure, function and operating principle of this application, it can be used to meet the application requirements of this solution.

[0060] Example 1

[0061] like Figure 1 As shown, this application proposes an automated device for simultaneous retraction of the liver and stomach during laparoscopic pancreatic surgery, comprising:

[0062] First support tube 2 and second support tube 14;

[0063] One end of the first support tube 2 and the second support tube 14 are elastically connected, and the other end is connected by a slip buckle 9;

[0064] The first support tube 2 is provided with a first airbag 4 and a first elastic traction belt 5;

[0065] The second support tube 14 is provided with a second airbag 12 and a second elastic traction belt 11.

[0066] The main body of the device is equipped with two inflatable air bladders and two elastic traction straps. The air bladders are used to pull on the liver, and the elastic traction straps are used to pull on the stomach. The two ends of the device are brought out of the body from the abdominal wall and can be fixed in place and the tension can be adjusted.

[0067] The aforementioned traction device is a disposable medical device. The main body (support tube) is a linear tubular structure with a certain degree of rigidity and flexibility (elastic element 1 with a circular arc structure), and its overall length is approximately 80cm. The cross-section is circular with a diameter of approximately 2mm.

[0068] like Figure 2 As shown, the middle section of the tubular device, about 6 cm long, is an airless structure. About 3 cm from the midpoint on each side, there is an air bladder (an air bladder on the support tube, with air flowing between the inside and outside of the support tube; air is preferentially drawn and released using a syringe). Each air bladder is about 8-10 cm long and, when inflated, forms a cylinder with a maximum diameter of 1 cm.

[0069] The device has an inflation port at one end for inflating and deflating the two airbags.

[0070] As an optional implementation of this application, it may also include:

[0071] Elastic element 1, one end of the first support tube 2 and the second support tube 14 are respectively fixed to both ends of the elastic element 1;

[0072] The elastic element 1 has an arc-shaped structure.

[0073] The first support tube 2 and the second support tube 14 need to be pulled and tightened to a certain extent. Therefore, the lower end connection of the first support tube 2 and the second support tube 14 needs to have a certain elasticity. Here, an elastic element 1 with an arc structure (elastic sheet or elastic tube, etc.) is used. The two parts are fixedly connected to the lower ends of the first support tube 2 and the second support tube 14 respectively. Under the tension of the buckle 9, the first support tube 2 and the second support tube 14 can be elastically adjusted.

[0074] As an alternative implementation of this application, optionally,

[0075] Both the first support tube 2 and the second support tube 14 are hollow inside and each is provided with an internal air tube 15 for external air to be vented to their respective airbags.

[0076] The first support tube 2 is provided with a first air hole 3, and the first airbag 4 is connected to the internal air tube 15 inside the first support tube 2 through the first air hole 3.

[0077] The second support tube 14 is provided with a second air hole 13, and the second airbag 12 is connected to the internal air tube 15 inside the second support tube 14 through the second air hole 13.

[0078] Specific combination Figure 2 Based on the above description, after the air is drawn in and out, the gas enters and exits the airbag through the internal air tube 15.

[0079] As an optional embodiment of this application, the fixing point of the first elastic traction belt 5 is optionally located on the first support tube 2 at the lower end of the first airbag 4; the fixing point of the second elastic traction belt 11 is located on the second support tube 14 at the lower end of the second airbag 12.

[0080] specific:

[0081] An elastic band approximately 25cm long, 3mm wide, and 2mm high is fixed on each side, starting about 2cm from the midpoint. One end is fixed to the main body of the traction device's support tube, while the other end is free (during surgery, it is fixed to the tube wall in the non-balloon area using endoscopic vascular clamps). Both ends of the traction device are designed as a pair of loose, self-locking straps, which can be self-fixed externally, and the tightness of the traction straps can be adjusted as needed.

[0082] As an optional embodiment of this application, the slipknot cable tie 9 may optionally include:

[0083] The snap fastener 7 is located at the upper end of the first support tube 2;

[0084] Cable tie 8 is located at the upper end of the second support tube 14;

[0085] The snap fastener 7 and the cable tie 8 can be connected loosely or tightly. The snap fastener cable tie has a loose-tight connection structure.

[0086] The slipknot 7 and the cable tie 8 can work together to pull the first support tube 2 and the second support tube 14 on the left and right sides. For the use of the slipknot cable tie, please refer to the structure of existing slipknot cable ties.

[0087] As an optional implementation of this application, it may also include:

[0088] The first air inlet 6 is located at the upper part of the first support tube 2 and is connected to the internal air tube 15 inside the first support tube 2.

[0089] The second air inlet 10 is located at the upper part of the second support tube 14 and is connected to the internal air tube 15 inside the second support tube 14.

[0090] The first inflation port 6 and the second inflation port 10 are respectively connected to an external air pump, which inflates and deflates their respective airbags.

[0091] The inflation port is connected to the inside of the support tube and is linked to the internal air tube 15. Inflation and deflation can be performed using a syringe or an air pump.

[0092] Therefore, this procedure can achieve the following medical and surgical effects:

[0093] 1. The liver traction device is equipped with an inflatable airbag. After inflation, it prevents sharp cutting damage to the liver during traction. The traction effect can be adjusted by changing the size of the airbag, which can effectively traction the left and right sides of the liver.

[0094] 2. Using two elastic traction straps to simultaneously pull the antrum and body of the stomach, fully exposing the neck, body, and tail of the pancreas, is effective and has minimal impact on the blood supply to the stomach.

[0095] 3. The traction device is equipped with a releasable buckle device at both ends, which makes it easy to fix and adjust the tightness repeatedly.

[0096] 4. A special laparoscopic hook is installed to bring the two ends of the intra-abdominal traction device to the outside of the body.

[0097] The invention is implemented as follows: Partial opening of the hepatogastric and gastrocolic ligaments is performed laparoscopically. The traction device is inserted into the abdominal cavity through the main operating port. The tube with a 6cm section in the center of the device (without the air bladder) is fixed to the liver border of the hepatogastric ligament using 2-3 laparoscopic vascular clamps. Small incisions of 2-3mm are made at appropriate locations below the costal margins on both sides of the upper abdomen. A specially designed laparoscopic suture device is used to guide both ends of the traction device to the outside of the body. A certain amount of gas is inflated into the air bladder using a syringe through the inflation port at one end. The loosely fastened ligaments at both ends are adjusted to pull the liver to the appropriate height. Laparoscopically, the elastic traction bands on both sides are wrapped from the lower to the upper side of the small bend to the anterior wall of the stomach. The elastic bands are adjusted according to surgical needs to pull the antrum and body of the stomach respectively. Laparoscopic vascular clamps are used to fix the elastic traction bands to the non-air bladder area of ​​the traction device body. After the device for the liver and stomach is properly installed, the subsequent surgical procedures can be performed. During the surgical procedure, the tension of the traction device can be adjusted by changing the size of the balloon or using the loose elastic bandage, depending on the traction requirements. Before the end of the surgical procedure, the external elastic bandage is loosened, the balloon is aspirated with a syringe, and both ends of the traction device are returned to the abdominal cavity. After removing the gastric traction bandage and the hepatic round ligament fixation clamp, the device is removed through the main operating port.

[0098] Example 2

[0099] like Figure 3 As shown, in this embodiment, in order to avoid the slipknot ties and inflation ports affecting the wounds in the abdominal cavity when they enter the abdominal cavity, the upper end of the support tube is made into a separate tube structure.

[0100] As an optional implementation of this application, it may also include:

[0101] The first separation tube 16 is screwed onto the upper end face of the first support tube 2, and the first air inlet 6 is provided on the first separation tube 16.

[0102] When the first separation tube 16 is connected to the first support tube 2, the first air inlet 6 is connected to the internal air tube 15 inside the first support tube 2.

[0103] The upper end face of the second support tube 14 and the second air inlet 10 thereon have the same structure as above.

[0104] The slipknot and inflation port are set on the separation tube. When the device is inserted into the abdominal cavity, the two ends of the support tube (the internal trachea 15 is sealed before insertion) are made with small incisions of 2-3 mm at appropriate positions below the left and right costal margins of the upper abdomen. A special laparoscopic hook is used to guide the two ends of the traction device to the outside of the body.

[0105] After guiding both ends of the support tube to the outside, connect the separation tube at the upper end of the support tube, install the slipknot cable ties and the inflation port on the support tube body, and then inflate, deflate and adjust the tightness.

[0106] The upper end faces of the first support tube 2 and the second support tube 14 can both adopt the above-mentioned separation tube structure to avoid interference with the abdominal incision when the sling and the inflation port enter and exit the incision.

[0107] Example 3

[0108] like Figure 4 As shown in this embodiment, in order to obtain timely information on the strain between the airbag pressure and the support tube of the automated device for simultaneous traction of the liver and stomach during laparoscopic pancreatic surgery, and to avoid excessive airbag pressure and excessive deformation between the support tubes, the strain between the airbag pressure and the support tube is monitored.

[0109] As an optional implementation of this application, it may also include:

[0110] A pressure monitoring module is provided in both the first airbag 4 and the second airbag 12, for monitoring the pressure data inside the airbag and sending the pressure data to an external controller via a data line;

[0111] The controller is used to receive and process the pressure data, generate the corresponding internal pressure value of the airbag, and send the internal pressure value of the airbag to the electronic screen.

[0112] An electronic screen is used to receive and display the internal pressure values ​​of the first airbag 4 and the second airbag 12.

[0113] The power module is used for power supply;

[0114] The pressure monitoring module, electronic screen, and power supply module are electrically connected to the controller.

[0115] As an optional implementation of this application, it may also include:

[0116] A strain gauge is disposed on the elastic element 1 to monitor the strain data of the elastic element 1 and transmit the strain data to an external controller via a data line.

[0117] The controller receives and processes the strain data, generates the corresponding strain force value, and sends and displays the strain force value on the electronic screen;

[0118] The strain gauge is electrically connected to the controller.

[0119] The airbag is equipped with a pressure monitoring module, which may be a miniature pressure sensor or a pressure resistor. The monitored pressure data is transmitted to an external controller via a data cable running along the internal airway of the support tube. The controller processes the data to obtain the corresponding internal pressure value of the airbag and displays it on an electronic screen in the external operating room, allowing medical staff to easily monitor the internal pressure of the airbag. The internal pressure of the airbag can be adjusted according to the air pressure reading.

[0120] A strain gauge is attached to the curved surface of the elastic element 1 to monitor the strain of the elastic element 1. The stress acting inside the elastic element 1 is transferred to the strain gauge, and the stress magnitude is measured by the deformation of the metal layer of the strain gauge.

[0121] Using the same data cable method as the pressure monitoring module, strain data is sent to an external controller. The controller processes the data to obtain the corresponding stress value, which is then sent and displayed on an electronic screen in the external operating room. This allows medical staff to easily view the stress value of elastic element 1. The stress value can be used to determine whether the slip-on cable tie is too loose or too tight.

[0122] For inflating and deflating the airbag, this method preferably uses a syringe for manual inflation and deflation.

[0123] However, the airbag can also be inflated and deflated by an air pump controlled by the controller. The inflation and deflation parameters can be preset in the controller, and during the operation, the air pump can be controlled to automatically inflate and deflate the airbag according to the preset inflation and deflation parameters.

[0124] Example 4

[0125] Based on the implementation principle of Embodiment 1, this application, in another aspect, proposes a method for using an automated device for simultaneous traction of the liver and stomach during laparoscopic pancreatic surgery, comprising the following steps:

[0126] Partial opening of the hepatogastric ligament and gastrocolic ligament under laparoscopy;

[0127] The automated traction device is inserted into the abdominal cavity through the main operating port;

[0128] The support tube in the middle of the device without the air bladder area is fixed to the liver edge of the hepatogastric ligament using 2-3 endoscopic vascular clamps.

[0129] Make small incisions of 2-3mm at appropriate locations below the left and right costal margins in the upper abdomen. Use a specially designed laparoscopic suture hook to guide the two ends of the traction automation device out of the body through the small incisions.

[0130] A certain amount of gas is injected into the balloon through the air inlet at one end using a syringe outside the body, causing the balloon to inflate. The loose buckle straps at both ends are adjusted to pull the left and right livers to the appropriate height.

[0131] The elastic traction bands on both sides are wrapped from bottom to top along the small bend to the anterior wall of the stomach. The elastic bands on both sides are adjusted according to the needs of the surgery to pull the antrum and body of the stomach respectively. The elastic traction bands are fixed to the non-balloon area of ​​the traction automation device using endoscopic vascular clamps.

[0132] After the automated traction device for the liver and stomach is installed, the surgical procedure is performed. During the procedure, the tension of the traction is adjusted by adjusting the size of the airbag or the loose straps as needed.

[0133] See the description of Example 1 above for details.
