[0103] Some embodiments of the present disclosure provide an injection device 10 for surgical training. Figure 1 A schematic structural diagram of a liquid injection device 10 according to some embodiments of the present disclosure is shown. Figure 2 A side view of an injection device 10 according to some embodiments of the present disclosure is shown. The injection device 10 can be used to inject liquid into a training target (not shown in the figure). The training target can be used for surgical training, and the user can perform simulated surgical operations on the training target to perform surgical training. In some embodiments, the training target can be a biological tissue specimen, such as a kidney, a heart, etc. In some embodiments, the training target can be an organ simulator, which can be used to simulate a biological organ, and the organ simulator can be made of a flexible material. The injection device 10 can inject liquid into the training target during surgical training to simulate scenes in real surgical operations.

[0104] like Figure 1 and Figure 2As shown, the liquid injection device 10 may include a liquid reservoir 11, an infusion tube 12 and a gas delivery component 13. The liquid reservoir 11 can be used to store liquid, and the liquid stored in the liquid reservoir 11 can be used to simulate blood, tissue fluid and other liquids in the lumen of biological tissue. In some embodiments, the liquid reservoir 11 may include a base 111, a cylindrical body 112 and a accommodating chamber 113. The cylindrical body 112 may be sealed on the base 111. The accommodating chamber 113 is formed in the base 111 and the cylindrical body 112, and the accommodating chamber 113 can be used to store liquid. In some embodiments, the cylindrical body 112 may be transparent, and the cylindrical body 112 may include a plurality of scale lines for indicating the volume of the liquid in the accommodating chamber 113.

[0105] The inlet of the infusion tube 12 can be connected to the liquid reservoir 11. Figure 1 As shown, the base 111 may include a liquid outlet 1111 , through which the liquid stored in the liquid reservoir 11 may flow out. Figure 3 FIG. 1 shows a partial structural diagram of the liquid injection device 10 according to some embodiments of the present disclosure from a bottom perspective. Figure 3 As shown, the liquid reservoir 11 may further include a liquid outlet cavity 1112 fixedly disposed at the bottom of the base 111 , the inlet of the liquid outlet cavity 1112 is communicated with the liquid outlet 1111 , and the outlet of the liquid outlet cavity 1112 is communicated with the inlet of the infusion tube 12 .

[0106] The outlet of the infusion tube 12 can be used to output liquid. In some embodiments, the outlet of the infusion tube 12 can be connected to a training target (not shown in the figure) to output liquid to the training target. In some embodiments, the injection device 10 can also include a tower connector 14, which can be provided at the end of the infusion tube 12. Based on this, it is convenient to connect with the lumens of various training targets with different radial sizes (for example, blood vessels, lymphatic vessels, etc.), and it helps to improve the stability of the connection. In some embodiments, the proximal end of the infusion tube 12 can be connected to the reservoir 11 through the valve 121, based on which the user can operate the valve 121 to perform operations such as starting or stopping the injection of the training target. As Figure 3 As shown, the inlet of the valve 121 may include a liquid outlet interface 1211, and the valve 121 may be connected to the liquid outlet cavity 1112 through the liquid outlet interface 1211. The outlet of the valve 121 may include an infusion interface 1212, and the infusion tube 12 may be assembled or disassembled through the infusion interface 1212.

[0107] The gas delivery component 13 is arranged above the liquid reservoir 11, and the gas delivery component 13 may include an air inlet channel 131 and a pressure pump 132. The air outlet of the air inlet channel 131 may be connected to the liquid reservoir 11 to transmit gas to the liquid reservoir 11. The pressure pump 132 may be arranged on the air inlet channel 131, and the pressure pump 132 may be used to pump the gas in the air inlet channel 131 into the liquid reservoir 11. In some embodiments, the air inlet of the air inlet channel 131 may be open to connect to the air in the environment. Under the action of the pressure pump 132, the gas delivery component 13 may draw air from the environment into the air inlet channel 131 and then pump it into the liquid reservoir 11. Based on this, the air pressure in the liquid reservoir 11 increases, thereby increasing the pressure of the liquid injected into the training target through the injection device 10, thereby better simulating the pressure of the liquid in the biological tissue. Those skilled in the art will appreciate that the air inlet channel 131 may include multiple sections of pipes (e.g., a pipe disposed above the pressure pump 132 and an air delivery pipe 1311 disposed below the pressure pump 132) for delivering gas to the liquid reservoir 11 through the pressure pump 132. In some embodiments, the gas delivery component 13 may further include a one-way air valve (not shown in the figures), which may be disposed at the air outlet of the air inlet channel 131 and located at the very end of the air delivery component 13. The input end of the one-way air valve may be in communication with the air inlet channel 131, and the output end of the one-way air valve may be in communication with the liquid reservoir 11. In some embodiments, as Figure 1 As shown, the outlet of the pressure pump 132 can be connected to a one-way valve via a gas pipe 1311. Those skilled in the art will appreciate that a one-way valve can restrict gas flow from its input to its output, preventing it from flowing back. Consequently, the pressure pump allows gas to flow from the outside into the reservoir 11 but prevents it from flowing out, thereby increasing the gas pressure within the reservoir 11.

[0108] Figure 4 FIG. 1 shows a schematic diagram of the exploded structure of the liquid injection device 10 according to some embodiments of the present disclosure. Figure 4 As shown, in some embodiments, the liquid reservoir 11 may further include a cover 114. The cover 114 may be disposed above the cylindrical body 112 and may be detachably connected to the cylindrical body 112. In some embodiments, the radial dimension of the cover 114 may be larger than the radial dimension of the cylindrical body 112 so as to be sleeved on the upper end opening of the cylindrical body 112. The cover 114 may include a plate-shaped portion 1141 and an edge portion 1142. The plate-shaped portion 1141 is capable of covering the upper end opening of the cylindrical body 112. The edge portion 1142 may be fixedly connected to the plate-shaped portion 1141 (for example, integrally formed), and the edge portion 1142 may be annular and extend downward to facilitate connection with the cylindrical portion 112. In some embodiments, the outer side of the edge portion 1142 may include an anti-slip structure to facilitate the user to remove or install the cover 114.

[0109] like Figure 4 As shown, in some embodiments, the inner side of the edge portion 1142 may include a sealing strip (not shown), and / or the cylindrical body 112 may include a sealing strip 1121 disposed on the outer side of the opening edge thereof, so that the cover 114 and the cylindrical body 112 are sealed together via the sealing strip. In some embodiments, the inner side of the edge portion 1142 of the cover 114 may be threadedly connected to the outer side of the opening edge of the cylindrical body 112. In some embodiments, the user can remove the cover 114 to add liquid to the reservoir 11, etc.

[0110] At least a portion of the gas delivery assembly 13 can be fixedly mounted above the cover 114. The cover 114 can include a central through hole (not shown), and the air inlet channel 131 can communicate with the central through hole to deliver ambient air into the liquid reservoir 11. In some embodiments, a one-way air valve can be embedded in the cover 114 to facilitate communication with the liquid reservoir 11 and to help secure the position of the one-way air valve.

[0111] In some embodiments, the gas delivery assembly 13 may further include a pressure sensor and a pressure controller (not shown). The pressure sensor is used to detect the air pressure within the accommodating cavity 113. The pressure sensor in this embodiment may be a suitable pressure sensor, such as a piezoresistive sensor or a capacitive pressure sensor. In some embodiments, the pressure sensor may be embedded in the cover 114 or disposed on the lower surface of the cover 114 to facilitate detection of the air pressure within the accommodating cavity 113. In some embodiments, the pressure sensor may be fixed to the lower surface of the cover 114 by adhesive bonding, welding, or other suitable means.

[0112] A pressure controller can be disposed above the cover 114 and can communicate with a pressure sensor to obtain information about the air pressure within the containment chamber 113. In some embodiments, the pressure controller and pressure sensor can communicate via a wired transmission. The cover 114 can include a cable guide hole (not shown) to allow the communication cable between the pressure controller and the pressure sensor to pass through. The pressure controller can be connected to the pressure pump 132 to control the pressure pump based on the air pressure within the containment chamber 113. For example, if the air pressure within the containment chamber 113 falls below a preset pressure, the pressure controller can send a control signal to the pressure pump to activate the pressure pump, thereby increasing the air pressure within the containment chamber 113. If the air pressure within the containment chamber 113 reaches the preset pressure, the pressure controller can send a control signal to the pressure pump to deactivate the pressure pump. Those skilled in the art will appreciate that the preset pressure can be set based on a reference blood pressure value for the surgical subject (e.g., a human or animal).

[0113] In some embodiments, as Figure 1As shown, the gas delivery assembly 13 may further include a first power source and a gas delivery assembly housing 133. The first power source may be used to power the pressure sensor and the pressure controller, and the first power source may power the pressure sensor and the pressure controller via a power supply cable. In some embodiments, the first power source may be disposed on the cover 114. In some embodiments, the pressure sensor and the pressure controller may also be powered by an external power source, one end of which may be connected to the pressure sensor or the pressure controller, and the other end of which may extend out of the liquid injection device 10 for connection to the external power source.

[0114] like Figure 1 As shown, the gas delivery assembly housing 133 can be cylindrical and can be fixedly mounted above the cover 114. In some embodiments, the cover 114 can include a connection base 1143 that protrudes from the upper surface of the cover 114. The lower end of the gas delivery assembly housing 133 can be connected to the connection base 1143 to facilitate its placement above the cover 114. In some embodiments, the gas delivery assembly housing 133 can be fixedly mounted to the connection base 1143 by a suitable method such as bonding.

[0115] like Figure 1 As shown, the gas delivery assembly housing 133 can cover the pressure pump 132, the first power source, and at least a portion of the air inlet channel 131. In some embodiments, the gas delivery assembly 13 may further include a cover plate 134 and an air inlet cavity (not shown). The cover plate 134 can cover the upper opening of the gas delivery assembly housing 133. The air inlet cavity can be located below the cover plate 134 and can communicate with the air inlet of the air inlet channel. The cover plate 134 can include multiple air inlet holes 1341 that can communicate with the air inlet cavity (not shown). External gas can then enter the air inlet cavity and subsequently enter the liquid reservoir 11 through the air inlet holes 1341 of the cover plate 134. In some embodiments, the pressure controller and the first power source can be integrated on a circuit board 1342, which can be fixedly disposed below the cover plate 134, for example, below the air inlet cavity. In some embodiments, the pressure pump 132 can be fixedly connected to the cover plate 134 to secure its position.

[0116] like Figures 1 to 3 As shown, in some embodiments, the liquid injection device 10 may further include a stirring assembly 15. The stirring assembly 15 may include a stirring rotor 151. The stirring rotor 151 may be located within the receiving chamber 113 and disposed above the base 111. The stirring rotor 151 extends radially along the receiving chamber 113. The stirring rotor 151 can rotate about the longitudinal center axis of the receiving chamber 113 to stir the liquid within the receiving chamber 113. In some embodiments, the stirring assembly 15 can stir the liquid within the receiving chamber 113 to prepare the liquid and simultaneously help solidify the liquid within the instant noodle receiving chamber 113.

[0117] In some embodiments, as Figure 3 As shown, the stirring assembly 15 may further include a stirring motor 152 and a rotating member 153. The stirring motor 152 may be disposed below the base 111. In some embodiments, the stirring motor 152 may be fixedly mounted below the base 111 via a motor bracket 154 fixedly mounted below the base 111. The output shaft (not shown) of the stirring motor 152 may be colinear with the longitudinal center axis of the accommodating chamber 113. The rotating member 153 may be disposed below the base 111 and extend radially from the base 111. The rotating member 153 may be connected to the output shaft of the stirring motor 152. For example, the center of the rotating member 153 may be fixedly connected to the output shaft of the stirring motor 152. In this manner, the output shaft of the stirring motor 152 can drive the rotating member 153 to rotate. The rotating member 153 is magnetically coupled to the stirring rotor 151. Therefore, when the rotating member 153 rotates, the rotating member 153 can also drive the stirring rotor 151 to rotate. In some embodiments, both the stirring rotor 151 and the rotating member 153 may be magnetic.

[0118] In some embodiments, the stirring assembly 15 may further include a second power source (not shown). The second power source may be used to power the stirring motor. In some embodiments, the second power source may be disposed below the base 111. In other embodiments, the stirring motor 152 may be powered by an external power source, and a power cable may extend from the injection assembly to connect to the external power source.

[0119] like Figure 1 As shown, in some embodiments, the liquid injection device 10 may further include a support assembly 16. The support assembly 16 may include a support base 161 and a support housing 162. The support base 161 may be located at the bottom of the liquid injection device 10 to support the liquid injection device 10. The support base 161 allows the liquid injection device 10 to be placed on an operating platform for easy use. In some embodiments, the support base 161 may include a base plate (not shown) and a support edge 1611 disposed along the circumference of the base plate. In some embodiments, the bottom of the support edge 1611 may include an anti-slip pad or anti-slip structure to prevent slipping during use. In some embodiments, the stirring motor 152 may be fixedly mounted on the base plate. The support housing 162 may be cylindrical, with the lower end of the support housing 162 attached to the support base 161 (e.g., by bonding or integral molding), and the upper end of the support housing 162 may be connected to the base 111 of the liquid reservoir 11 (e.g., by bonding or snap-on connection). The support housing 162 may cover the stirring motor 152, the rotating member 153, and the second power source.

[0120] like Figure 1As shown, in some embodiments, the support housing 162 may include multiple ventilation holes 1621. Those skilled in the art will appreciate that, through the multiple ventilation holes 1621, the space within the support housing 162 can be connected to the outside world, thereby preventing the rotating member 153 from rotating within the support housing 162 and generating loud noise. In some embodiments, the support base 161 (e.g., the bottom plate) may include multiple heat dissipation holes (not shown). Those skilled in the art will appreciate that, through the multiple heat dissipation holes, the heat generated by the operation of the stirring motor 152 can be dissipated to the outside world, thereby preventing the stirring motor 152 from overheating and affecting the use of the liquid injection device 10.

[0121] In some embodiments, the injection device 10 may further include a heating film (not shown). The heating film may be disposed on the lower surface of the base 111 of the reservoir 11, for example, by being adhered to the lower surface of the base 111. In some embodiments, the heating film may be an electric heating film, powered by a power supply disposed within the support housing 162 or an external power source, thereby generating heat. Those skilled in the art will appreciate that the heating film disposed on the lower surface of the base 111 can heat the liquid within the reservoir 11, thereby preventing the liquid from dropping to excessively low temperatures and potentially affecting surgical training.

[0122] Some embodiments of the present disclosure further provide a surgical training system, which may include a surgical training mold 30 and a liquid injection device for surgical training (eg, the liquid injection device 10 ) according to any one of the embodiments of the present disclosure. Figure 5 A schematic structural diagram of a surgical training mold 30 according to some embodiments of the present disclosure is shown. Figure 6 FIG. 1 is a schematic diagram showing the exploded structure of a surgical training mold 30 according to some embodiments of the present disclosure. Figure 7 A schematic diagram of the decomposed structure of a surgical training mold 30 according to some embodiments of the present disclosure is shown. The surgical training mold 30 can be used to carry a training target 20. In some embodiments, the training target 20 can be an organ simulator, which can be used to simulate a biological organ, and the organ simulator can be made of a flexible material. In other embodiments, the training target 20 can be a biological tissue specimen, such as a biological kidney, heart, or other tissue specimen. The infusion tube 12 of the injection device 10 can be connected to the training target 20 to inject liquid into the training target 20. In some embodiments, the user can perform simulated surgical operations on the training target 20 set on the surgical training mold 30 to perform surgical training. During surgical training, the injection device 10 can inject liquid into the training target 20 to simulate the liquid in real biological tissue (such as blood, lymph, etc.), so as to simulate the reactions that occur during a real operation, which helps to improve the effect of surgical training.

[0123] In some embodiments, the surgical training mold 30 may include a cavity simulation component 310. The cavity simulation component 310 can be used to provide an operating space for performing simulated surgical operations. The cavity simulation component 310 may include multiple entrances, such as entrances 31221, 31412, etc. The multiple entrances may include multiple flexible skin simulation parts and multiple openings provided on the multiple skin simulation parts. For example, the entrance 31221 may include a skin simulation part 31221a and a cross opening 31221b provided on the skin simulation part 31221a, and the entrance 31412 may include a skin simulation part 31412a and a cross opening 31412b provided on the skin simulation part 31412a. It will be understood by those skilled in the art that the opening is not limited to the cross-shaped opening shown in the figure, but may also be any suitable opening. The entrance may include a skin simulation part and a single opening or multiple openings provided on the skin simulation part. Those skilled in the art may provide a single opening or multiple openings at the entrance as needed.

[0124] In some embodiments, the inlet can be embedded in the cavity-simulating component 310. For example, the edge of the skin-simulating portion can be embedded in the cavity-simulating component 310 by bonding or other means. In some embodiments, the inlet can also include a circumferential edge protruding from the surface of the cavity-simulating component 310 (for example, the inlet 31221 can include a circumferential edge 31221c). The circumferential edge can be embedded in the cavity-simulating component 310 by bonding or other means, and the skin-simulating portion can be circumferentially connected to the circumferential edge by bonding or other means. In some embodiments, the opening can be provided in the skin-simulating portion by cutting or other means.

[0125] In some embodiments, the end of the infusion tube 12 of the injection device 10 can be inserted into the cavity simulation component 310 through the inlet, and then connected to the training target 20 to inject the training target 20. In some embodiments, the inlet can be used to allow at least one surgical instrument to be inserted into the cavity simulation component 310 through its opening to perform a simulated surgical operation in the operating space provided by the cavity simulation component 310. In some embodiments, the inlet can be used to allow the end of a sheath (not shown) to be inserted into the cavity simulation component 310 through its opening, and at least one surgical instrument can be inserted into the cavity simulation component 310 through the channel provided by the sheath to perform a simulated surgical operation in the cavity simulation component 310. In some embodiments, the center of the opening can be located at the center of the inlet to facilitate the insertion of surgical instruments or sheaths through the opening.

[0126] In some embodiments, the multiple inlets can be oriented in multiple directions, such as horizontally, vertically, or at an angle to the horizontal. Therefore, surgical instruments can be inserted into the cavity simulation assembly 310 through different inlets to simulate surgical procedures in different cavities (e.g., oral cavity, chest cavity, rectum, etc.), or in different surgical positions.

[0127] In some embodiments, as Figures 5 to 7 As shown, the cavity simulation assembly 310 may include a main body 311, a first operating window 312, and a first cavity 313. The main body 311 may include a base 3111. Those skilled in the art will appreciate that during simulated surgical training, the base 3111 may be placed on a platform to facilitate the user's simulated surgical procedures. The lower surface of the base 3111 may be provided with a suitable anti-slip structure or anti-slip coating to prevent the surgical training mold 30 from slipping and affecting the simulated surgical procedure.

[0128] The first operating window 312 can be detachably connected to the main body 311. In some embodiments, the first operating window 312 may include a protrusion (not shown) circumferentially disposed on its open side, and the main body 311 may include a first groove 3112 circumferentially disposed on its open side that is engageable with the protrusion of the first operating window 312. The main body 311 and the first operating window 312 can be detachably connected via the protrusion and the first groove 3112. Those skilled in the art will appreciate that the main body 311 and the first operating window 312 can be detachably connected via any other suitable structure.

[0129] The first cavity 313 is located between the main body 311 and the first operation window 312. The first cavity 313 can be used to simulate the abdominal cavity. The user can perform a simulated surgical operation in the first cavity 313, for example, performing a simulated surgical operation on the training target 20 disposed in the first cavity 313 to simulate a surgical operation performed in the abdominal cavity.

[0130] In some embodiments, as Figures 5 to 7 As shown, the first operating window 312 may include a first circumferential portion 3121 and a first oblique portion 3122. The first circumferential portion 3121 may be connected to the main body 311. For example, the first circumferential portion 3121 may be engaged with the main body 311 in the circumferential direction of the open side. The first oblique portion 3122 may be connected to the first circumferential portion 3121. The circumference of the first oblique portion 3122 may be connected to the first circumferential portion 3121, for example, by bonding or integral molding. The first oblique portion 3122 may be at an oblique angle relative to the base 3111.

[0131] In some embodiments, the multiple entrances of the cavity simulation component 310 may include at least one first circumferential entrance disposed in the first circumferential portion 3121, such as entrances 31211 and 31212. The multiple entrances may also include at least one first oblique entrance 31221 disposed in the first oblique portion 3122. The opening of the first oblique entrance 31221 may be used to simulate an opening in the lower abdomen. A user may enter the first cavity 313 through the first oblique entrance 31221 to perform simulated surgical procedures, thereby simulating various surgical procedures such as those involved in gynecological procedures.

[0132] In some embodiments, as Figures 5 to 7 As shown, the first circumferential portion 3121 may include a first side portion 3121a, an oppositely disposed first oblique front portion 3121b and a first oblique rear portion 3121c, and a first top portion 3121d. The first side portion 3121a may be perpendicular to the base 3111. In some embodiments, at least one first circumferential inlet may include at least one simulated natural cavity inlet 31211 disposed on the first side portion 3121a, the opening of which may be used to simulate a natural cavity opening such as the anus, allowing the user to perform simulated surgical procedures for various procedures such as those involving anorectal surgery. The first circumferential inlet may also include at least one oblique front simulated lateral abdomen inlet 31212 disposed on the first oblique front portion 3121b and / or at least one oblique rear simulated lateral abdomen inlet disposed on the first oblique rear portion 3121c (not shown in the figure, but may be disposed opposite the oblique front simulated lateral abdomen inlet 31212). The openings of the anterior and posterior simulated lateral abdomen entrances 31212 and 31233 can be used to simulate lateral abdomen openings, allowing users to simulate various surgical procedures, such as those involving urology. The first circumferential entrance may also include at least one top simulated abdomen entrance 31213 disposed at the first top portion 3121d, allowing users to simulate surgical procedures involving entering a patient's body from directly above the abdomen.

[0133] In some embodiments, the first operating window 312 may further include at least one rib-like structure (not shown) disposed inside the first oblique front portion 3121b and the first oblique rear portion 3121c. The rib-like structure may be attached to the inside of the first oblique front portion 3121b and the first oblique rear portion 3121c by gluing or other means. This allows the user to simulate performing a surgical operation within the patient's abdominal cavity by passing through the intercostal space.

[0134] In some embodiments, as Figures 5 to 7As shown, the main body 311 may further include a support frame 3113 disposed on the base 3111. The support frame 3113 may include a transverse support portion 3113a, a front longitudinal support portion 3113b, a rear longitudinal support portion 3113c, an oblique front support portion 3113d, and an oblique rear support portion 3113e.

The oblique front support portion 3113d is disposed between the front longitudinal support portion 3113b and the transverse support portion 3113a, and the oblique rear support portion 3113e is disposed between the rear longitudinal support portion 3113c and the transverse support portion 3113a.

[0135] The first side portion 3121a of the first circumferential portion 3121 can be connected to the base 3111, the front longitudinal support portion 3113b, and the rear longitudinal support portion 3113c of the main body 311, for example, by engaging a protrusion on the edge of the first side portion 3121a with a groove provided at a corresponding position on the base 3111, the front longitudinal support portion 3113b, and the rear longitudinal support portion 3113c. The first oblique front portion 3121b can be connected to the oblique front support portion 3113d, and the first oblique rear portion 3121c can be connected to the oblique rear support portion 3113e.

[0136] In some embodiments, as Figures 5 to 7 As shown, the cavity simulation component 310 may further include a second operating window 314 and a second cavity 315. The second operating window 314 may be arranged opposite to the first operating window 312, and the second operating window 314 may be connected to the main body 311. In some embodiments, as shown in FIG. Figure 7 As shown, the second operating window 314 can be detachably connected to the main body 311. In some embodiments, the second operating window 314 may include a protrusion structure 3140 circumferentially arranged on its open side, and the main body 311 may include a second groove 3114 circumferentially arranged on its open side and capable of engaging with the protrusion structure of the second operating window 314. The main body 311 and the second operating window 314 can be detachably connected via the protrusion structure 3140 and the second groove 3114. It will be appreciated by those skilled in the art that the main body 311 and the second operating window 314 can be detachably connected via any other suitable structure.

[0137] The second cavity 315 is located between the main body 311 and the second operation window 314. The second cavity 315 can be used to simulate the chest cavity. A user can perform a simulated surgical operation within the second cavity 315, such as performing a simulated surgical operation on a training target 20 disposed within the second cavity 315, to simulate a surgical operation within the chest cavity. The second cavity 315 can be in communication with the first cavity 313.

[0138] In some embodiments, as Figures 5 to 7 As shown, the second operating window 314 may include a second circumferential portion 3141 and a second oblique portion 3142. The second circumferential portion 3141 may be connected to the main body 311. For example, the second circumferential portion 3141 may be engaged with the main body 311 in the circumferential direction of the open side. The second oblique portion 3142 may be connected to the second circumferential portion 3141. The second oblique portion 3142 may be connected to the second circumferential portion 3141 in the circumferential direction, for example, by bonding or integral molding. The second oblique portion 3142 may be at an oblique angle relative to the base 3111.

[0139] In some embodiments, the multiple inlets of the cavity simulation assembly 310 may include at least one second circumferential inlet disposed in the second circumferential portion 3141, such as inlet 31411. The multiple inlets may also include at least one second oblique inlet 31421 disposed in the second oblique portion 3142. The opening of the second oblique inlet 31421 may be used to simulate an oral opening, etc. A user may enter the second cavity 315 through the second oblique inlet 31421 to perform a simulated surgical procedure, thereby simulating a surgical procedure such as entering a patient's body through the oral cavity.

[0140] In some embodiments, as Figures 5 to 7 As shown, the second circumferential portion 3141 may include a second side portion 3141a, an oppositely disposed second oblique front portion 3141b, a second oblique rear portion 3141c, and a second top portion 3141d. The second side portion 3141a may be perpendicular to the base 3111. The second side portion 3141a is disposed opposite the first side portion 3121a and can be connected to the base 3111, the front longitudinal support portion 3113b, and the rear longitudinal support portion 3113c of the main body 311, for example, by engaging a protrusion on the edge of the second side portion 3141a with a groove provided at a corresponding position on the base 3111, the front longitudinal support portion 3113b, and the rear longitudinal support portion 3113c. The second oblique front portion 3141b can be connected to the oblique front support portion 3113d, and the second oblique rear portion 3141c can be connected to the oblique rear support portion 3113e. The second top portion 3141d can be connected to the lateral supporting portion 3113a.

[0141] In some embodiments, the at least one second circumferential inlet may include at least one simulated neck inlet 31411 disposed on the second side portion 3141a, which allows a user to perform simulated surgical procedures entering a patient's body from the neck. The second circumferential inlet may also include at least one simulated lateral chest inlet 31412 disposed on the second oblique front portion 3141b and / or at least one simulated lateral chest inlet 31413 disposed on the second oblique rear portion 3141c, the openings of which may be used to simulate openings of the lateral chest, allowing the user to perform simulated surgical procedures for various procedures, such as those involving thoracic surgery. The second circumferential inlet may also include at least one simulated top chest inlet 31414 disposed on the second top portion 3141d, allowing the user to simulate simulated surgical procedures entering a patient's body from directly above the chest.

[0142] In some embodiments, surgical instruments enter the cavity simulation component 310 through an entrance set in the first operating window 312 (for example, a simulated natural cavity entrance 31211, a first oblique entrance 31221, etc.) to perform simulated surgical operations. The user can disassemble the second operating window 314 so that the training target 20 set therein can be adjusted on the open side of the cavity simulation component 310 to facilitate the performance of simulated surgical operations.

[0143] In some embodiments, the dimensions (e.g., height and width) of the first operating window 312 can be larger than those of the second operating window 314. Those skilled in the art will appreciate that during intra-abdominal surgery, the abdominal cavity is often insufflated to facilitate surgical procedures. Therefore, making the first operating window 312 larger than the second operating window 314 can better simulate the size differences between the thoracic and abdominal cavities.

[0144] In some embodiments, the first operating window 312 and the second operating window 314 may be transparent. When a user performs a simulated surgical operation through the cavity simulation component 310 , other users may observe the simulated surgical operation through the first operating window 312 or the second operating window 314 .

[0145] In some embodiments, as Figure 7 As shown, the surgical training mold 30 may further include a receiving assembly 340. The receiving assembly 340 is detachably disposed on the base 3111, and the receiving assembly 340 may include a receiving platform 341. The receiving platform 341 may be used to carry the training target 20 (e.g., a biological tissue specimen such as a kidney or heart). In some embodiments, the receiving assembly 340 may further include an anti-slip coating or anti-slip structure (not shown) disposed on the upper surface of the receiving platform 341 to prevent the training target 20 from sliding relative to the receiving platform 341 and affecting the simulated surgical operation. As an alternative embodiment, the receiving platform 341 may be made of an anti-slip material.

[0146] Figure 8A FIG. 3 is a schematic diagram showing the structure of the receiving assembly 340 according to some embodiments of the present disclosure. Figure 8A As shown, in some embodiments, the receiving assembly 340 may further include a plurality of legs 342, which may be disposed below the receiving platform 340 and may be disposed on the base 3111. In some embodiments, the bottoms of the plurality of legs 342 may be provided with anti-slip pads to prevent the receiving assembly 340 from sliding relative to the base 3111, thereby preventing interference with the simulated surgical procedure. In some embodiments, the bottoms of the plurality of legs 342 may include a plurality of recessed structures (not shown), and the base 3111 may include a raised structure (not shown) that can engage with the recessed structures. When the receiving assembly 340 is disposed in the cavity simulation assembly 310, the recessed structures may engage with the raised structures to prevent the receiving assembly 340 from sliding.

[0147] In some embodiments, the receiving platform 341 may further include multiple leakage holes 3411. The base 3111 may further include a liquid collection trough and a liquid outlet (not shown). The liquid collection trough may be circumferentially arranged on the upper surface of the base 3111. The liquid outlet may be connected to the liquid collection trough, and the liquid outlet may be connected to the liquid outlet pipe and the liquid collection device. When the user performs a simulated surgical operation such as cutting on the training target 20, the liquid injected into the training target 20 by the injection device 10 will flow out of the training target 20. This liquid can flow through the leakage holes 3411 on the receiving platform 341 to the base 3111. In some embodiments, the upper surface of the base 3111 may have a protruding center and concave edges to facilitate the flow of liquid onto the base 3111 into the liquid collection trough. The liquid outlet may be located at a corner of the base 3111, and the liquid collection trough may be tilted toward this corner to facilitate the flow of blood, tissue fluid, etc. collected in the liquid collection trough to the liquid outlet, and then through the liquid outlet pipe to the liquid collection device. In some embodiments, the liquid collecting device may include any suitable liquid collecting device such as a liquid collecting box or a liquid collecting barrel.

[0148] In some embodiments, the receiving assembly 340 may further include an electrode sheet (not shown). The electrode sheet may be disposed on the receiving platform 341 and may contact the biological tissue specimen. The electrode sheet may be connected to a power source, for example, via a cable 343 and a plug 344 at the end of the cable 343. The cable 343 may be connected to the power source through the guide hole 3143 (see FIG. Figure 6 ) extends the cavity simulation assembly 310 to connect to a power source. The user can use the surgical training mold 30 to perform simulated surgical procedures using monopolar electrosurgical tools (e.g., monopolar electrocautery, monopolar electrosurgical hook, etc.). During the simulated surgical procedures, the monopolar electrosurgical tools can form a pathway with the electrode plates, allowing for cutting and other operations on the biological tissue specimen sandwiched between them.

[0149] In some embodiments, as Figure 8A As shown, the receiving platform 341 may further include a groove 3412 , which may be used to accommodate an electrode sheet. The groove 3412 may be provided on the upper surface of the receiving platform 341 to facilitate contact with a biological tissue specimen.

[0150] Figure 8B Schematic diagrams illustrating the structure of a receiving assembly 350 according to other embodiments of the present disclosure are shown. As an alternative to receiving assembly 340, in some embodiments, the surgical training mold 30 may include receiving assembly 350. Receiver assembly 350 is detachably mounted on base 3111 and may include a receiving platform 351 for supporting the training target 20. In some embodiments, the dimensions (e.g., length, width, etc.) of receiving assembly 350 may be smaller than those of receiving assembly 340 to facilitate supporting smaller tissues, such as a kidney.

[0151] In some embodiments, the electrode sheet can be set on the bottom of the receiving platform 351 by a suitable method such as pasting. The receiving platform 351 may include a slot in the middle, and the training target 20 can be set in the slot to contact the electrode sheet. In some embodiments, the receiving assembly 350 may include at least one fixing belt 352, one end of the at least one fixing belt 352 can be fixedly set on the upper surface of the receiving platform 351, and the other end of the at least one fixing belt 352 can be detachably connected to the upper surface of the receiving platform 351. At least one fixing belt 352 can be used to fix the training target 20. At least one fixing belt 352 can fix biological tissue specimens of smaller size.

[0152] The remaining technical details involved in the receiving component 350 are similar to those of the receiving component 340 and will not be repeated here to reduce repetition.

[0153] Figure 9A Schematic diagrams of the structure of a cavity simulation component 330 according to other embodiments of the present disclosure are shown. Figure 9B Schematic diagram of the exploded structure of the cavity simulation component 330 according to some other embodiments of the present disclosure is shown. As an alternative embodiment of the cavity simulation component 310, in some embodiments, the surgical training mold 30 may include the cavity simulation component 330. The cavity simulation component 330 can be used to provide an operating space for performing simulated surgical operations. Figure 9A and Figure 9BAs shown, the cavity simulation component 330 may include multiple inlets, such as inlets 3312, 3321, etc. The multiple inlets may include multiple flexible skin simulation parts and multiple openings provided on the skin simulation parts. The multiple inlets may be used to allow at least one surgical instrument (e.g., clamps, curved scissors, single hook, endoscope, etc.) to extend through its opening into the cavity simulation component 330, so as to perform simulated surgical operations within the operating space provided by the cavity simulation component 330. The multiple inlets may also be used to allow the infusion tube 12 of the injection device 10 to extend through its opening into the cavity simulation component 330, so as to inject the training target provided in the cavity simulation component 330. It will be understood by those skilled in the art that the inlet may include a skin simulation part and a single opening or multiple openings provided on the skin simulation part, and those skilled in the art may provide a single opening or multiple openings at the inlet as needed.

[0154] like Figure 9A and Figure 9B As shown, the cavity simulation assembly 330 may include a main body, a first operating window 331, and a second operating window 332. The main body may include a base 3311. The first operating window 331 may be detachably connected to the main body. For example, the first operating window 331 may include protrusions (not shown) disposed on opposite sides of the bottom edge thereof. The base 3311 may include slide rails 33111 disposed at corresponding positions. The first operating window 331 and the base 3311 may be connected or disconnected via the protrusions and slide rails 33111, thereby allowing the open side of the first operating window 331 to be positioned outside the open side of the second operating window 332. The second operating window 332 may be fixed to the base 3311, for example, by bonding, integral molding, or other suitable means.

[0155] The cavity simulation assembly 330 may further include a first cavity 333 located between the first operating window 331 and the base 3311, and a second cavity 334 located between the second operating window 332 and the base 3311. The first cavity 333 may be used to simulate the abdominal cavity, and the second cavity 334 may be used to simulate the thoracic cavity. The first cavity 333 may be larger than the second cavity 334 to better simulate the patient's abdominal cavity being insufflated during surgery.

[0156] Other technical details involved in the cavity simulation component 330 are similar to those of the cavity simulation component 310 and will not be described again to reduce repetition.

[0157] In some embodiments, the surgical training mold 30 may also include a smoke removal assembly (not shown). The distal end of the smoke removal assembly can extend into the cavity simulation assembly 310 to absorb smoke generated during surgery, thereby avoiding obstruction of the user's surgical field and facilitating surgical procedures.
