Description

[Technical Field]

[0001] The present invention relates to a training tool, and more particularly to a training device for simulating bile duct stone removal surgery, in which a medical professional performs a simulated bile duct stone removal surgery in an abdominal module in which a bile duct model is provided. [Background technology]

[0002] Endoscopic surgery has the advantages of small wounds and minimal bleeding, and is widely used in various surgical procedures. Cholangioscopy is a specialized technique for observing and treating common bile duct diseases. Cholangioscopy requires advanced skills to operate, so traditionally, cholangioscopy requires observing others, operating the cholangioscopy yourself, or operating it on animals. However, these methods have issues such as ethical concerns, limited resources, and inconsistent learning outcomes.

[0003] In recent years, the practice of simultaneously diagnosing and treating diseases by inserting an endoscope into the mouth, passing it through the esophagus and stomach, and then reaching the second part of the duodenum to locate the exit of the patient's biliary and pancreatic ducts is becoming more common. This involves injecting contrast media into the biliary and pancreatic ducts via a catheter, assessing whether there are any lesions in the biliary and pancreatic ducts, or determining whether there are stones, strictures, or other lesions. While this technique is often used by general physicians, it is still relatively unfamiliar to experienced physicians. However, the surgical approach of removing stones through endoscopic cholangiopancreatography, as described above, is not suitable for all patients. For example, this method cannot be used in patients undergoing gastrointestinal resection or reconstructive surgery for other conditions, or in patients with unstable vital signs who need to be treated for biliary stone-related complications.

[0004] Nowadays, with the maturity and advancement of 3D printing technology, medical professionals can perform 3D reconstruction and detailed adjustments on the computed tomography images of patients with biliary stones, and then use 3D printing technology to create models that include the common bile duct, intrahepatic bile duct, extrahepatic bile duct, and part of the duodenum. This will provide a cholangioscopic teaching tool with a material and anatomical location that closely resembles the bile duct, thereby eliminating the shortcomings of conventional technology. Summary of the Invention [Problem to be solved by the invention]

[0005] The purpose of this invention is to provide a training device for simulating bile duct stone removal surgery that allows medical professionals to train in bile duct stone removal surgery using a cholangioscope by simulating the biliary tract structure of a patient.

The processing unit processes and calculates the changes in the physical quantities detected and returned by the plurality of first detection units on the wall surfaces of the bile duct units, and if the changes exceed a set pressure threshold, the processing unit controls the alarm unit to generate an alarm signal.

[0007] Furthermore, the bile duct unit is formed by assembling a plurality of bile duct bodies, each of which has at least one connection portion, and which is assembled to another connection portion of an adjacent bile duct body.

[0008] Furthermore, the biliary module includes a second connecting pipe unit, one end of which is connected to the bile duct unit and the other end of which is connected to the circulation module, and the second connecting pipe unit is assembled into another of the through holes.

[0009] Furthermore, the circulation module includes a liquid storage unit and a pump unit, one end of which is connected to the liquid storage unit and the other end of which is connected to the second connecting pipe unit, and which transports the liquid stored in the liquid storage unit from the connected second connecting pipe unit to the bile duct unit, or recovers the liquid in the bile duct unit to the liquid storage unit via the second connecting pipe unit.

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

[0011] The device further includes a stone unit, which can be housed in the bile duct unit, and a second detection unit is provided on the outer periphery of the stone unit, which detects a change in contact area and transmits the change in contact area to the processing unit, which receives and processes the change in contact area returned by the second detection unit, and if the change in contact area 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, the plurality of first detection units are provided on the inner wall surfaces of the plurality of bile duct bodies, respectively.

[0013] Furthermore, the plurality of bile duct bodies are recessed at one of the connection portions to form an annular groove. [Effects of the Invention]

The required fluid volume and inner wall pressure value can also be provided to the bile duct unit through the circulation module, making the bile duct stone removal surgery simulation training device of the present invention a teaching platform that can be used repeatedly and complies with relevant ethical standards.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Regarding the technology of the present invention, referring to FIGS. 1 to 5, the present invention provides a bile duct stone removal surgery simulation training device 100 for medical personnel to train in bile duct stone removal surgery based on the location of stones in a patient's biliary tract, and the bile duct stone removal surgery simulation training device 100 mainly includes an abdominal cavity module 10, a biliary module 20, a circulation module 30, a stone unit 40, and a control module 50. The abdominal cavity module 10 is provided with a receiving space 11 and a plurality of through holes 12 , which penetrate the peripheral side wall of the abdominal cavity module 10 and communicate with the receiving space 11 . The biliary module 20 is assembled into the accommodation space 11 of the abdominal cavity module 10. Referring again to FIGS. 1 to 4, the biliary module 20 includes a first connecting tube unit 21, a second connecting tube unit 22, and a bile duct unit 23. One end of the first connecting tube unit 21 is connected to the bile duct unit 23 and they communicate with each other, and the other end of the first connecting tube unit 21 is assembled into one through-hole 12 of the abdominal cavity module 10. One end of the second connecting tube unit 22 is connected to the bile duct unit 23 and they communicate with each other, and the other end of the second connecting tube unit 22 is assembled into another through-hole 12 of the abdominal cavity module 10. The bile duct unit 23 may be integrally molded, or may be formed by assembling a plurality of bile duct bodies 231. Each bile duct body 231 has at least one connecting portion 232, and the connecting portion 232 is assembled to another connecting portion 232 of another adjacent bile duct body 231. Furthermore, one of the connecting portions 232 of the multiple bile duct bodies 231 is recessed to form an annular groove 233, and the assembled bile duct body 231 can be locked in the annular groove 233. Referring again to FIG. 4 , the wall surface of the bile duct body 231 can be assembled to another bile duct body 231, and the other bile duct body 231 can be locked in the annular groove 233 on the wall of the bile duct body 231. However, this is not limited to this embodiment. 1 to 5, 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, and the pump unit 32 transports the liquid 200 stored in the liquid storage unit 31 from the connected second connecting pipe unit 22 to the bile duct unit 23, or recovers the liquid 200 in the bile duct unit 23 to the liquid storage unit 31 via the second connecting pipe unit 22. The stone unit 40 can be accommodated in the bile duct unit 23, and simulates the position of the patient's stone in the bile duct unit 23. A second detection unit 41 is provided on the outer periphery of the stone unit 40, and the second detection unit 41 detects the amount of change in contact area. The control module 50 is assembled in the accommodation space 11 of the abdominal cavity module 10, and includes a processing unit 51, an alarm unit 52, and a plurality of first detection units 53. The processing unit 51 is electrically connected to the alarm unit 52 and the plurality of first detection units 53, and the plurality of first detection units 53 are assembled on the inner wall surfaces of the bile duct units 23 of the biliary module 20, i.e., the inner wall surfaces of the plurality of bile duct bodies 231, respectively, and the plurality of first detection units 53 detect changes in physical quantities on the wall surfaces of the bile duct units 23, and the processing unit 51 can be electrically connected to the pump unit 32. However, this is not limited to this form. The processing unit 51 processes and calculates the changes in physical quantities returned by the multiple first detection units 53 when they detect the wall surface of the bile duct unit 23, and if the changes exceed a set pressure threshold, the processing unit 51 controls the warning unit 52 to generate a warning signal.The processing unit 51 also receives and processes the change in contact area returned by the second detection unit 41, and if the change in contact area is greater than the threshold value, the processing unit 51 controls the warning unit 52 to generate a warning signal.

[0017] Referring again to FIGS. 1 to 4, the bile duct stone removal surgery simulation training device 100 of the present invention primarily uses 3D printing technology and computed tomography images of the patient's biliary tract to manufacture and use a biliary module 20 that resembles the patient's biliary tract structure. First, referring to FIGS. 2 to 4, the biliary module 20 may be formed by assembling multiple stages according to needs. Accordingly, a biliary unit 23 may be formed by combining multiple adjacent biliary bodies 231 with multiple connecting portions 232. Furthermore, multiple annular grooves 233 are used to engage with the connecting portions 232 of other biliary bodies 231, and the first connecting tube unit 21 and the second connecting tube unit 22 are respectively assembled to the corresponding biliary bodies 231 and then protrude through the corresponding through-holes 12. Referring again to FIG. 5, the biliary module 20 may be integrally molded, and the first connecting tube unit 21 and the second connecting tube unit 22 are also respectively connected to the connecting portions 232 of the corresponding biliary units 23. 2, a plurality of first detection units 53 are provided on the inner wall surfaces of the plurality of bile duct bodies 231 of the bile duct unit 23, and a second detection unit 41 is provided on the outer circumferential surface of the stone unit 40. Therefore, after the medical staff places the biliary module 20 into the receiving space 11 of the abdominal cavity module 10, they insert the stone unit 40 through the first connection unit 21, one end of which protrudes into the through-hole 12, and then adjust and install the stone unit 40 to the position of the bile duct body 231 corresponding to the bile duct unit 23 of the patient's stone. Then, the circulation module 30 transports the liquid 200 in the liquid storage unit 31 from the pump unit 32 to the bile duct unit 23 or recovers the liquid 200 from the bile duct unit 23 according to needs. The processing unit 51 performs processing and calculations based on the pressure values ​​returned by the plurality of first detection units 53. In addition, when a medical professional starts a simulation of a bile duct stone removal surgery, the cholangioscope is inserted through the first connecting tube unit 21, and when the cholangioscope comes into contact with the multiple first detection units 53 on the inner wall surfaces of the multiple bile duct bodies 231, the multiple first detection units 53 detect changes in the physical quantities of the wall surfaces and provide these changes in physical quantities to the processing unit 51, which processes and calculates the changes in the physical quantities returned by them and determines whether to control the warning unit 52 to issue a warning signal based on whether the pressure exceeds a set threshold value; or, if the cholangioscope is able to hold a stone, the second detection unit 41 of the stone unit 40 provides the change in contact area to the processing unit 51, which processes and calculates the change in contact area returned by it and determines whether the change in contact area exceeds a set threshold value based on whether the stone removal was successful or whether to issue a warning signal to alert the patient. This makes the bile duct stone removal surgery simulation training device 100 of the present invention a teaching platform that is reusable and compliant with relevant ethical standards.

[0018] As can be seen from the above, the training device 100 for simulating bile duct stone removal surgery of the present invention mainly uses 3D printing technology and computed tomography images of the patient's bile duct to manufacture the bile duct module 20, and depending on the position where the stone is to be removed from the patient, the stone unit 40 is placed at a corresponding position on the bile duct unit 23. In other words, 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 and placed up to the bile duct body 231 corresponding to the bile duct unit 23. Furthermore, a cholangioscope is inserted through the first connecting tube unit 21 to simulate the bile duct stone removal surgery. When the cholangioscope contacts the multiple first detection units 53 on the inner wall surfaces of the multiple bile duct bodies 231, the processing unit 51 processes and calculates the changes in the physical quantities returned by the first detection units 53. The processing unit 51 determines whether to control the alarm unit 52 to issue a warning signal based on whether the pressure exceeds a preset threshold, or determines whether the stone removal is successful or whether to issue a warning signal based on whether the change in the contact area of ​​the stone unit 40 exceeds the threshold. The circulation module 30 can also provide the bile duct unit 23 with the required volume of liquid 200 and the required pressure value on the inner wall surfaces of the bile duct bodies 231 from the second connecting tube unit 22. This makes the bile duct stone removal surgery simulation training device 100 of the present invention a teaching platform that can be used repeatedly and complies with relevant ethical standards.
