Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical demonstration tools, and particularly relates to a weight loss surgery demonstration model. BACKGROUND

[0002] The most common surgical procedure in surgical weight loss surgery is sleeve gastrectomy and Roux-en-Y gastric bypass surgery, both of which can be performed using minimally invasive surgery, usually under laparoscopy through multiple small incisions in the upper abdomen to insert laparoscopic instruments to perform surgery on the gastrointestinal tract, limit food intake and nutrient absorption, and achieve weight loss and metabolic function improvement. The principle of sleeve gastrectomy is to cut the large bend of the stomach along the guide stomach tube to form a small stomach sac of about 70-150ml, reduce the stomach capacity, and reduce the secretion of gastrointestinal hormones that stimulate hunger; the principle of Roux-en-Y gastric bypass surgery is to first divide the stomach into an upper and lower part, a smaller stomach sac, and a larger lower part, then cut off the small intestine, rearrange the position of the small intestine and anastomose, change the path of food through the digestive tract, slow down the gastric emptying speed, and reduce the absorption.

[0003] In the process of determining a treatment plan or teaching, medical staff usually need to explain the specific condition of the patient, the possible surgical plan, the part to be resected during the implementation of the surgery, etc. to the patient, the patient's family or medical students, and currently, Flash animation is usually used to demonstrate the surgical process in the process of doctor-patient communication and clinical teaching, which makes it difficult for the patient, the patient's family or medical students to efficiently and intuitively understand the operation process of the surgery. The establishment and application of a surgical demonstration model is a bridge connecting basic research and clinical practice, and the surgical demonstration model can help the patient, the patient's family or medical students to intuitively understand the operation process of the surgery, however, the existing weight loss surgery demonstration model does not have the function of dynamic demonstration, and the connection between the elements is mechanical, which is not vivid and the demonstration effect is poor.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0033] Example 1

[0034] like Figures 1 to 7 As shown, a weight loss surgery demonstration model includes a display platform and a human gastrointestinal model set on the display platform. The human gastrointestinal model has a cutting position, and a closing mechanism is set on the cutting position. A control board and a built-in power supply are set inside the display platform. The closing mechanism and the built-in power supply are electrically connected to the control terminal. The closing mechanism is used to simulate the cutting and closing actions of the cutting position during the surgery.

[0035] In this embodiment, the opening and closing mechanism includes an electromagnet and a magnetic attractor. The electromagnet is set on both sides of the cutting position of the human gastrointestinal model, and the magnetic attractor is set inside the display platform. The electromagnet is electrically connected to the control terminal.

[0036] The control terminal outputs a power supply signal to the built-in power supply, controlling the built-in power supply to output current to the electromagnet, so that the electromagnet receives current and generates a magnetic field, and the cutting position closes under the action of the magnetic field; the control terminal outputs a power off signal to the built-in power supply, controlling the built-in power supply to disconnect the current output to the electromagnet, so that the electromagnet is de-energized, the magnetic field disappears, and the cutting position opens in the state of losing the magnetic field.

[0037] like Figures 3 to 7 As shown, the human gastrointestinal model includes a sleeve stomach model and a resected portion. Electromagnets are installed at both the anastomosis site of the sleeve stomach model and the resected portion. The sleeve stomach model and the resected portion are anastomosed together by the electromagnets and magnetically connected to the display platform. When the sleeve stomach model and the resected portion are anastomosed together, it represents the basic state of an intact and continuous gastrointestinal tract.

[0038] In this embodiment, electromagnets are distributed at the anastomosis edges of the sleeve stomach model and the anastomosis edges of the resected portion. When current flows into the electromagnets, they generate a magnetic field, causing the anastomosis edges of the sleeve stomach model and the resected portion to align and be attracted to the display platform. The resected portion and the sleeve stomach model are aligned, and the cutting position is closed. When the current is turned off, the electromagnets lose their electromagnetic field, and the anastomosis edges of the sleeve stomach model and the resected portion separate and are no longer attracted to the display platform, thus separating the cutting positions.

[0039] As shown in Figure 2 The human gastrointestinal model comprises a silica gel layer and a light-emitting layer laid on the silica gel layer, and the light-emitting layer is electrically connected to the control end. The light-emitting layer can be arranged on the outer wall or the inner wall of the gastrointestinal model shaped by the silica gel, and in this embodiment, the silica gel is shaped into a sleeve-shaped stomach model and a resection part model, the light-emitting layer is laid on the outer wall of the sleeve-shaped stomach model and the resection part, the control end outputs a signal of turning on the light-emitting layer to the light-emitting layer, and the light-emitting layer can be sequentially turned on from top to bottom to show the process of food entering the gastrointestinal tract from the esophagus, and the capacity of the human gastrointestinal model can be shown by the brightness of the light-emitting layer, and the flow rate of the food can be shown by the speed of the light flickering.

[0040] The light-emitting layer can display red, yellow, blue and green. In this embodiment, the light-emitting layer on the resection part and the sleeve-shaped stomach model sequentially displays yellow from top to bottom, which is used to represent the process that the food passes through the resection part and the sleeve-shaped stomach model at the same time; the light-emitting layer on the sleeve-shaped stomach model sequentially displays green from top to bottom, which is used to represent the process that the food only passes through the sleeve-shaped stomach model; and the light-emitting layer on both sides of the cutting position displays red, which represents the postoperative complications such as bleeding or fistula at the cutting position.

[0041] In this embodiment, the light-emitting layer adopts a flexible LED electronic screen. The flexible LED electronic screen can display different light effects by changing the display form of the light beads of different colors, and different light effects can be adjusted according to different needs, so that the human gastrointestinal model has better demonstration effect. The light-emitting layer can also adopt a programmable light strip, and the programmable light strip can display different states according to the preset program by programming the programmable light strip.

[0042] As shown in Figure 1 The display platform further comprises a control key electrically connected to the control end. In this embodiment, the control key comprises a control key A, a control key B, a control key C, a control key D and a control key E. The user can send instructions to the control end by triggering different control keys, so that the human gastrointestinal model demonstrates different performances according to the preset program. The mobile control terminal can be bound to the control end of the display platform through WIFI or Bluetooth, and the demonstration of the human gastrointestinal model can be controlled through the mobile control terminal.

[0043] As shown in Figure 1 The outer side of the display platform is provided with a charging interface electrically connected to the built-in power supply. In this embodiment, the charging interface can be inserted into a power cord, and the Zhanghe mechanism and the light-emitting layer can be powered on through the charging interface. At the same time, the built-in power supply can also be charged, which is convenient for the application to be used alone after the power cord is pulled out.

[0044] The use method of the embodiment one of the application is as follows:

[0045] Press the control key A, as shown in Figure 3 the yellow light is sequentially lit from the light emitting layer on the resection part and the sleeve-shaped stomach model from top to bottom, demonstrating the process of food passing through the resection part and the sleeve-shaped stomach model at the same time.

[0046] Press the control key B, as shown in Figure 4 all the electromagnets are connected with current, the anastomotic edge of the sleeve-shaped stomach model and the anastomotic edge of the resection part are adsorbed on the display platform, and the sleeve-shaped stomach model and the resection part are anastomosed with each other, demonstrating the closed state of the cutting position when the surgical instrument is operated in the operation.

[0047] Press the control key C, as shown in Figure 5 the electromagnets of the upper edge of the anastomotic port of the sleeve-shaped stomach model and the upper edge of the anastomotic port of the resection part are disconnected with current, the upper edge of the anastomotic port of the sleeve-shaped stomach model is separated from the upper edge of the anastomotic port of the resection part, and the process of cutting the cutting position by the surgical instrument in the operation is demonstrated.

[0048] Press the control key D, as shown in Figure 6 the green light is sequentially lit from the light emitting layer on the sleeve-shaped stomach model from top to bottom, demonstrating the process of food passing through the sleeve-shaped stomach model after the operation.

[0054] In the embodiment, the light-emitting layers on the small gastric capsule model, the subtotal gastric model and the distal jejunum model all sequentially display yellow from top to bottom, which is used to represent the process that food passes through the small gastric capsule model, the subtotal gastric model and the distal jejunum model at the same time; the light-emitting layers on the upper half (digestive limbs) of the small gastric capsule model and the distal jejunum model sequentially display yellow from top to bottom, which is used to represent the process that food only passes through the small gastric capsule model and the distal jejunum model, the upper half of the subtotal gastric model sequentially displays blue from top to bottom, which is used to represent the process that digestive juice passes through the upper half of the subtotal gastric model, and the lower half of the distal jejunum model sequentially displays green from top to bottom, which is used to represent the process that food and digestive juice pass through the lower half of the distal jejunum model at the same time.

[0055] The use method of the second embodiment of the present application is as follows:

[0056] Press the control key A, as shown in Figure 3 , the yellow light sequentially lights up from the light-emitting layers on the small gastric capsule model, the subtotal gastric model and the distal jejunum model from top to bottom, demonstrating the process that food passes through the small gastric capsule model, the subtotal gastric model and the distal jejunum model at the same time.

[0057] Press the control key B, as shown in Figure 9 , the current is supplied to all the electromagnets, the anastomotic edges of the small gastric capsule model, the top end of the subtotal gastric model, the proximal jejunum model and the distal jejunum model are all adsorbed on the display platform, and the small gastric capsule model and the top end of the subtotal gastric model are anastomosed with each other, and the proximal jejunum model and the distal jejunum model are anastomosed with each other, demonstrating the state that the cutting position is closed when the surgical instruments are operated in the surgery.

[0058] Press the control key C, as shown in Figure 10As shown, the current is turned off on the electromagnets at the upper edges of the anastomoses of the small gastric pouch model, the top of the large gastric model, the proximal jejunum model, and the distal jejunum model. The upper edge of the anastomose at the top of the large gastric model separates from the upper edge of the anastomose of the small gastric pouch model, and the upper edge of the anastomose of the distal jejunum model separates from the upper edge of the anastomose of the proximal jejunum model, demonstrating the process of surgical instruments cutting out the cutting position during surgery.

[0059] Press the control key D, as shown Figure 11 As shown, the top of the distal jejunum model is manually lifted and attached to the bottom of the small gastric pouch model. The top of the distal jejunum model is then attached to the bottom of the small gastric pouch model. The proximal jejunum model is then attached to the middle of the distal jejunum model, and the end of the proximal jejunum model is attached to the middle of the distal jejunum model. Yellow light sequentially illuminates from top to bottom in the luminous layers of the small gastric pouch model and the upper part of the distal jejunum model, demonstrating that food passes through the small gastric pouch model and the upper part of the distal jejunum model only after surgery. Blue light sequentially illuminates from top to bottom in the luminous layer of the large gastric pouch model, demonstrating that digestive juices pass through the large gastric pouch model only after surgery. Green light sequentially illuminates from top to bottom in the luminous layer of the lower part of the distal jejunum model, demonstrating that food and digestive juices converge at the proximal jejunum model and pass together through the lower part of the distal jejunum model after surgery.

[0062] In summary, this invention, through its opening and closing mechanism, can realistically simulate the process of surgical instruments cutting and closing the incision site, facilitating observation of the main surgical steps of sleeve gastrectomy and Roux-en-Y gastric bypass. The luminescent layer of this invention can simulate the process of food passing through different parts of the human gastrointestinal model before and after surgery, allowing observation of the pre- and post-operative food intake and digestion process without the need for physical objects, thus providing a better demonstration effect. Furthermore, the luminescent layer of this invention can also simulate the state of common postoperative complications at the incision site, demonstrating the effects of bleeding or fistula at the incision site after surgery, providing a more intuitive understanding of real surgical situations.
