Description

Technical Field

[0001] This utility model relates to a training tool, and more particularly to a bile duct stone removal simulation surgery training device that provides medical personnel with a bile duct model on an abdominal module to simulate bile duct stone removal surgery. Background Technology

[0002] Endoscopic techniques are widely used in various surgical procedures due to their advantages of small incisions and minimal bleeding. However, cholangioscopy is a technique specifically used to observe and treat diseases of the common bile duct, and its operation requires extremely high skill. Therefore, traditionally, the actual operation of cholangioscopy has mostly relied on observing others, performing the procedure oneself, or performing it on animals. However, these methods have ethical concerns, resource limitations, and inconsistent learning quality.

[0003] In recent years, an endoscope has been inserted into the mouth, through the esophagus and stomach, to reach the second part of the duodenum. After locating the exit of the bile and pancreatic ducts, contrast agents are injected into the bile and pancreatic ducts through a catheter to assess whether there are lesions in the bile ducts and pancreatic ducts, or to determine whether there are stones, strictures, or other lesions. There are more and more cases where disease diagnosis and treatment can be performed simultaneously. However, compared with the above techniques, general practitioners have much less experience than senior physicians. However, not every patient can accept the above surgical method of endoscopic cholecystoscopic lithotripsy. For example, patients who have undergone gastrointestinal resection and reconstruction surgery for other diseases cannot use the above method, or patients with unstable vital signs who need to manage bile duct stones and related complications.

[0004] Furthermore, considering the current maturity and advancement of 3D printing technology, medical professionals can use computed tomography images of patients with bile duct stones, and after 3D reconstruction and detailed adjustments, use 3D printing technology to create models including the common bile duct, intrahepatic and extrahepatic bile ducts, and part of the duodenum. Therefore, it is necessary to provide a teaching tool that provides realistic bile duct materials and anatomical positioning for cholangioscopy to overcome the lack of conventional knowledge. Utility Model Content

[0005] The purpose of this invention is to provide a bile duct stone removal simulation surgery training device that simulates the structure of a patient's bile duct to provide medical staff with training in bile duct stone removal surgery through choledochoscopy.

[0006] To achieve the above objectives, this utility model provides a bile duct stone removal simulation surgical training device for medical personnel to train in bile duct stone removal surgery based on the location of stones in a patient's bile duct. The bile duct stone removal simulation surgical training device mainly comprises: an abdominal cavity module with a receiving space and at least one through hole, each through hole penetrating the peripheral wall of the abdominal cavity module and communicating with the receiving space; a bile duct module assembled in the receiving space of the abdominal cavity module, the bile duct module including a first connecting tube unit and a bile duct unit, one end of the first connecting tube unit being connected to the bile duct unit and communicating with it, and the other end of the first connecting tube unit being assembled in the abdominal cavity module. The block has a through hole; and a control module is disposed in the accommodating space of the abdominal cavity module. The control module includes a processing unit, an alarm unit, and at least one first sensing unit. The processing unit is electrically connected to the alarm unit and each of the first sensing units. Each of the first sensing units is disposed on the inner wall of the bile duct unit of the bile duct module. Each of the first sensing units senses the physical quantity changes of the wall of the bile duct unit. When the processing unit processes and calculates that the physical quantity changes returned by the wall of the bile duct unit sensed by each of the first sensing units exceed a set pressure threshold, the processing unit controls the alarm unit to generate an alarm signal.

[0007] Furthermore, the bile duct unit is composed of multiple bile duct bodies, and each bile duct body has at least one connecting portion, which is connected to another connecting portion of an adjacent bile duct body.

[0008] Furthermore, the bile duct module includes a second connecting tube unit, one end of which is connected to the bile duct unit and the other end of which is connected to a circulation module, wherein the second connecting tube unit passes through another through hole.

[0009] Furthermore, the circulation module includes a liquid storage unit and a pump unit, with one end of the pump unit connected to the liquid storage unit and the other end connected to the second connecting pipe unit, for transporting the liquid stored in the liquid storage unit to the bile tube unit through the connected second connecting pipe unit, or for recovering the liquid in the bile tube unit to the liquid storage unit through the second connecting pipe unit.

[0010] Furthermore, the pump unit is electrically connected to the processing unit.

[0011] Furthermore, a stone unit can be housed in the bile duct unit, and a second sensing unit is provided on the outer periphery of the stone unit. The second sensing unit is used to sense the change in contact area and transmit the change in contact area to the processing unit. When the processing unit receives and processes the change in contact area transmitted back by the second sensing unit, which is greater than a threshold value for the change in contact area, the processing unit controls the warning unit to generate a warning signal.

[0012] Furthermore, each of the first sensing units is disposed on the inner wall surface of each of the bile duct bodies.

[0013] Furthermore, each of the bile duct bodies has an annular groove recessed in one of its connecting portions.

[0014] This utility model's bile duct stone removal simulation surgical training device mainly uses 3D printing technology to manufacture the bile duct module based on the patient's computed tomography (CT) image data of the bile duct. According to the location of the stone to be removed, the stone unit is positioned at the corresponding position of the bile duct unit. That is, the stone unit is inserted through the first connecting tube unit protruding from the through hole, and the stone unit is adjusted to the corresponding bile duct body. Then, a choledochoscope is inserted through the first connecting tube unit to simulate bile duct stone removal surgery. Specifically, when the choledochoscope contacts each inner wall surface of each bile duct... The first sensing unit, the processing unit will process and calculate whether the physical quantity change it returns exceeds the set pressure threshold to decide whether to control the warning unit to issue a warning signal, or whether the change in the contact area of ​​the stone unit exceeds the contact area change threshold to decide whether the stone removal is successful and issue a warning signal to remind. The circulation module can provide the required amount of fluid and the pressure value of the inner wall of the bile duct unit. Therefore, the bile duct stone removal simulation surgery training device of this utility model is a reusable teaching demonstration platform that complies with relevant ethical norms.

Figure 4 As shown, the wall of the bile duct body 231 can be assembled on another bile duct body 231, and the annular groove 233 on the wall of one bile duct body 231 can lock the other bile duct body 231, but is not limited thereto.

Figures 1 to 5 As shown, the circulation module 30 includes a liquid storage unit 31 and a pump unit 32. One end of the pump unit 32 is connected to the liquid storage unit 31, and the other end is connected to the second connecting pipe unit 22. The pump unit 32 is used to transport the liquid 200 stored in the liquid storage unit 31 to the bile tube unit 23 through the connected second connecting pipe unit 22, or to recover the liquid 200 in the bile tube unit 23 to the liquid storage unit 31 through the second connecting pipe unit 22.

[0046] A stone unit 40 is accommodated within the bile duct unit 23 to simulate the location of a patient's gallstone within the bile duct unit 23. A second sensing unit 41 is provided on the outer periphery of the stone unit 40 to sense changes in the contact area.

[0047] A control module 50 is disposed in the accommodating space 11 of the abdominal cavity module 10. The control module 50 includes a processing unit 51, an alarm unit 52 and a plurality of first sensing units 53.

The processing unit 51 may be electrically connected to the pump unit 32, but is not limited thereto.

[0048] Specifically, when the processing unit 51 processes and calculates the change in physical quantity returned by the wall of the bile duct unit 23 by the first sensing unit 53, which exceeds a set pressure threshold, the processing unit 51 controls the warning unit 52 to generate a warning signal. When the processing unit 51 receives and processes the change in contact area returned by the second sensing unit 41, which is greater than a contact area change threshold, the processing unit 51 controls the warning unit 52 to generate a warning signal.

[0049] First, please refer to the following: Figures 1 to 4 As shown, the bile duct stone removal simulation surgical training device 100 of this utility model mainly uses 3D printing technology and the patient's biliary tract computed tomography image data to manufacture a bile duct module 20 that is similar to the patient's bile duct structure through 3D printing technology. Please refer to [the relevant documentation]. Figures 2 to 4 As shown, the biliary module 20 can be assembled in segments as needed. Therefore, each adjacent bile duct body 231 can be combined through each connecting part 232 to form the bile duct unit 23. Each unit can be secured to the connecting part 232 of another bile duct body 231 through each annular groove 233. The first connecting tube unit 21 and the second connecting tube unit 22 are respectively assembled on the corresponding bile duct body 231 and then protrude from the corresponding through hole 12. Please refer to [further details omitted]. Figure 5 As shown, the biliary module 20 can also be integrally molded, and the first connecting tube unit 21 and the second connecting tube unit 22 are respectively connected to the connecting portion 232 of the corresponding biliary module 23.

Therefore, after the medical staff places the bile duct module 20 into the receiving space 11 of the abdominal cavity module 10, they insert the stone unit 40 from the first connecting unit 21 protruding from the through hole 12 at one end, and then adjust the stone unit 40 to the position of the patient's stone in the bile duct body 231 corresponding to the bile duct unit 23. The circulation module 30 then pumps the liquid 200 in the storage unit 31 to the bile duct unit 23 as needed through the pump unit 32, or recovers the liquid 200 from the bile duct unit 23. The processing unit 51 processes and calculates the pressure value returned by each of the first sensing units 53.

[0050] Furthermore, when medical staff begin simulating bile duct stone removal surgery, the choledochoscope is inserted through the first connecting tube unit 21. Therefore, when the choledochoscope contacts each of the first sensing units 53 on the inner wall of each bile duct body 231, each first sensing unit 53 senses the physical quantity change of its wall and provides this physical quantity change to the processing unit 51. The processing unit 51 processes and calculates whether the returned physical quantity change exceeds the set pressure threshold, and then decides whether to control the warning unit 52 to issue a warning signal. Alternatively, when the choledochoscope successfully grasps the stone, the second sensing unit 41 of the stone unit 40 provides the contact area change to the processing unit 51. The processing unit 51 processes and calculates whether the returned contact area change exceeds the set contact area change threshold to determine whether to indicate successful stone removal and issue a warning signal. Therefore, the bile duct stone removal simulation surgery training device 100 of this utility model is a reusable teaching and demonstration platform that complies with relevant ethical standards.

[0051] In summary, the bile duct stone removal simulation surgery trainer 100 of this utility model mainly uses 3D printing technology to manufacture the bile duct module 20 based on the computed tomography image data of the patient's bile duct. According to the location of the stone to be removed, the stone unit 40 is positioned at the corresponding position of the bile duct unit 23. That is, the stone unit 40 is inserted through the first connecting tube unit 21 protruding from the through hole 12, and the stone unit 40 is adjusted to the bile duct body 231 corresponding to the bile duct unit 23. Then, a choledochoscope is inserted through the first connecting tube unit 21 to simulate bile duct stone removal surgery. Specifically, when the choledochoscope contacts each of the first sensing points on the inner wall of each bile duct body 231... Unit 53, the processing unit 51 will process and calculate whether the change in the physical quantity returned by it exceeds the set pressure threshold, in order to decide whether to control the warning unit 52 to issue a warning signal, or whether the change in the contact area of ​​the stone unit 40 exceeds the contact area change threshold, in order to decide whether to successfully remove the stone and issue a warning signal to remind. Moreover, the circulation module 30 can provide the required volume of liquid 200 for the bile duct unit 23 and the required pressure value for the inner wall of the bile duct body 231 from the second connecting pipe unit 22 end. Therefore, the bile duct stone removal simulation surgery training device 100 of this utility model has reusability and is a teaching and demonstration platform that complies with relevant ethical norms.
