Detailed Description
In view of the above technical features, the main effects of the simulated bile and pancreatic duct structure for ERCP surgery simulation of the present invention will be clearly shown in the following examples.
Referring to fig. 1 to 3, an embodiment of the present invention discloses a simulated bile pancreatic duct structure for ERCP surgery simulation, comprising:
a biliary-pancreatic duct prosthesis 1 has a hollow biliary-pancreatic duct 11, one end of the biliary-pancreatic duct 11 being provided with a biliary-pancreatic duct orifice 12.
In the preferred embodiment of the present invention, the bile-pancreatic duct 11 comprises a common bile duct 111 and a pancreatic duct 112, and has a bile duct 113 and a total hepatic duct 114 in communication with the common bile duct 111, and the bile-pancreatic duct orifice 12 correspondingly comprises a total bile duct orifice 121 disposed at one end of the common bile duct 111, and a pancreatic duct orifice 122 disposed at one end of the pancreatic duct 112.
The thickness of the common bile duct 111, the pancreatic duct 112, the cholecyst duct 113 and the common hepatic duct 114, etc., and even the combination angle between them, can be configured according to the real human body condition, so that doctors and medical students can better grind the feeling of ERCP.
The bile-pancreatic duct prosthesis 1 further comprises a skirt 13, wherein the skirt 13 is disposed at one end of the bile-pancreatic duct 11 and adjacent to the bile-pancreatic duct orifice 12, preferably surrounding the bile-pancreatic duct orifice 12.
The bile-pancreatic duct 11 is made of an elastic material, such as silica gel, so that the Shore hardness (Shore OO) of the bile-pancreatic duct 11 is between 70 and 85, and the Shore hardness (Shore OO) of the skirt liner 13 is between 10 and 25.
A shell combined with the biliary-pancreatic duct prosthesis 1. The material of the shell is polyethylene terephthalate (polyethylene terephthalate, PET) or polyvinyl chloride (Polyvinyl Chloride, PVC), and the shell can be completely transparent, semitransparent or opaque according to the requirements.
In the preferred embodiment of the present invention, the housing comprises a first housing 2 and a second housing 3, the first housing 2 has a channel 21, and the second housing 3 has an opening 31 communicating with the channel 21. The first housing 2 further has a first coupling portion 22, the second housing 3 has a second coupling portion 32, the first housing 2 and the second housing 3 are coupled to each other via the first coupling portion 22 and the second coupling portion 32, and the housing has a receiving space (not shown) communicating with the channel 21 and adjacent to the opening 31.
Referring to fig. 3 and 4, when the first housing 2 and the second housing 3 are combined with each other, the biliopancreatic tube prosthesis 1 is located between the first housing 2 and the second housing 3, the channel 21 correspondingly accommodates the biliopancreatic tube 11, the biliopancreatic tube orifice 12 corresponds to the opening 31, the skirt liner 13 is located in the accommodating space, and the diameter of the inner wall of the channel 21 is 0.5 to 2.5 mm larger than the diameter of the outer wall of the biliopancreatic tube 11.
It should be noted that, because the rigidity of the skirt liner 13 is low, only the skirt liner 13 may be deformed to attach the first housing 2 and the second housing 3, and the accommodating space is the space between the first housing 2 and the second housing 3, so as to ensure that the skirt liner 13 can achieve good fixing and attaching effects.
In practical implementation, the accommodating space may be a fixing structure recessed on the first housing 2 and/or the second housing 3, or a small portion of deformable material may be used on a side of the first housing 2 and/or the second housing 3 away from the channel 21 to deform the skirt liner 13 to form the accommodating space.
Referring to fig. 3, 5 and 6, after the biliopancreatic duct prosthesis 1 is combined between the first housing 2 and the second housing 3, the ERCP exercise can be started.
For example, the device may be combined with a display and a general camera to directly capture the simulated bile and pancreatic duct structure for ERCP surgery simulation from the outside, or an X-ray image simulation device may be used to combine the simulated bile and pancreatic duct structure for ERCP surgery simulation with an X-ray image simulation device, for example, the aforementioned X-ray image simulation techniques such as CN201465396U patent application or chinese patent publication No. CN116564151 a.
A medical instrument A, such as a stone removal basket, guide wire, or the like, is then inserted into the bile duct 11 through the opening 31 and the bile duct orifice 12.
Because the first shell 2 and the second shell 3 are tightly attached to the skirt liner 13, gaps which are difficult to be penetrated by the medical instrument A by mistake are not easily formed around the opening 31, and meanwhile, the skirt liner 13 effectively simulates muscle tissues around the pancreatic duct orifice 12 of the gall bladder to assist doctors and medical students in training to control the medical instrument A, so that the medical instrument A is prevented from damaging the muscle tissues.
In the process of controlling the medical apparatus a to extend into the bile and pancreatic duct 11 by a doctor or a medical student, the medical apparatus a may not be maintained at the center of the bile and pancreatic duct 11, and if the medical apparatus a is deviated sideways, the bile and pancreatic duct 11 may be displaced.
At this time, a doctor or a physician can train how to continue to operate the medical device a under the situation that the biliopancreatic duct 11 is displaced, so as to avoid the risk of puncturing the medical device a.
Referring to fig. 7, another medical device B of a thicker thickness may cause the biliopancreatic duct 11 to expand.
At this time, the physician and medical practitioner can train how to continue to operate the medical device B in the situation where the biliopancreatic duct 11 is expanded, so as to avoid the risk of puncture and other injuries of the medical device B.
Referring to fig. 6 and 7, since the diameter of the inner wall of the channel 21 is 0.5 to 2.5 mm larger than the diameter of the outer wall of the bile and pancreatic duct 11, and the material of the bile and pancreatic duct 11 is the elastic material, the displacement and expansion of the bile and pancreatic duct 11 can be truly simulated, and the training of ERCP can be effectively assisted for doctors and medical students under the condition of using different medical instruments a and B.
While the operation, use and effectiveness of the present invention will be fully understood from the description of the embodiments, the above-described embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, i.e., the following claims and the description make simple and equivalent changes and modifications, which fall within the scope of the present invention.
