DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0033] like Figures 1 to 10 As shown, a laparoscopic ultrasonic endoscopic combined surgery training model for facilitating replacement of an organ module 2 in this embodiment includes a mounting base 1, at least one organ module 2 and at least two fixing devices 3; the number of the organ modules 2 can be freely set according to actual design requirements, and the number of the fixing devices 3 is adaptively set according to the number of the organ modules 2. For example, when one organ module 2 is set, two fixing devices 3 can be set; when two organ modules 2 are set, two fixing devices 3 can be respectively set for each organ module 2.

[0034] Furthermore, if Figure 3 As shown, the mounting base 1 is provided with at least two first mounting positions 11, and the number of the first mounting positions 11 can be freely set according to needs. Preferably, the number of the first mounting positions 11 is set to two; the two opposite side walls of the first mounting position 11 are provided with first card slots 12; Figure 4 As shown, at least two second mounting positions 21 are provided at the bottom of the organ module 2. The number of the second mounting positions 21 can be freely set as needed. Preferably, the number of the second mounting positions 21 is set to two; the two side walls opposite to the second mounting positions 21 are provided with second card slots 22;

[0035] like Figure 5 and Figure 6As shown, the fixing device 3 includes a first mounting block 31 and a second mounting block 32 rotatably arranged on the first mounting block 31; the first mounting block 31 is rotatably provided with a driving member and slidably penetrated with two first clamping blocks 34 respectively connected to the driving member; an elastic energy storage member is provided between the driving member and the first mounting block 31; the second mounting block 32 is connected to the driving member; a sliding block 36 is slidably penetrated on the side of the second mounting block 32 facing away from the first mounting block 31; a first spring 37 is provided between the sliding block 36 and the second mounting block 32; the second mounting block 32 is slidably penetrated with two second clamping blocks 38 capable of contacting and cooperating with the inclined surface of the sliding block 36;

[0036] like Figures 1 to 3 As shown, a slide groove 13 connected to the first mounting position 11 is provided on one side of the mounting base 1; a lever 4 is slidably provided in the slide groove 13; by sliding the lever 4, the lever 4 is brought into contact with the slider 36 and pushes the slider 36 to slide inward to overcome the elastic force of the first spring 37. During the process of sliding inward, the slider 36 contacts and cooperates with the inclined surfaces of the two second clamping blocks 38, thereby pushing the two second clamping blocks 38 to extend outward.

[0037] Specifically, when installing the organ module 2, the first mounting block 31 of each fixing device 3 is placed one by one into the second mounting position 21 of the organ module 2, and then the second mounting block 32 is rotated, and the second mounting block 32 drives the driving member to rotate relative to the first mounting block 31. The elastic energy storage member stores potential energy at this time, and the driving member causes the two first clamping blocks 34 to slide inward. At this time, the first mounting block 31 can be completely inserted into the second mounting position 21, and then the second mounting block 32 is released. At this time, the elastic energy storage member releases potential energy, causing the driving member to rotate in the opposite direction, thereby driving the two first clamping blocks 34 to slide outward, until the two first clamping blocks 34 are inserted into the corresponding second clamping slots 22 one by one, thereby realizing the installation between the organ module 2 and the fixing device 3;

[0038] When the organ module 2 is installed on the installation base 1, each second clamping block 38 can be slid inward first, and then each second mounting block 32 can be inserted into the first mounting position 11 of the installation base 1 one by one. After all the second mounting blocks 32 are placed in the first mounting position 11, the lever 4 is pushed from one end of the installation base 1 to the other end thereof. During the sliding process, the lever 4 pushes the slider 36 to overcome the elastic force of the first spring 37 and slide inward. During the inward sliding process, the slider 36 contacts and cooperates with the inclined surfaces of the two second clamping blocks 38, thereby pushing the two second clamping blocks 38 to extend outward until the second clamping blocks 38 are inserted into the corresponding first clamping grooves 12. At this time, the second clamping blocks 38 are in an extended state, and the slider 36 simultaneously keeps the two second clamping blocks 38 in an extended state, so that the organ module 2 is firmly installed on the installation base 1.

[0039] When the organ module 2 needs to be removed from the mounting base 1, the lever 4 is pushed again, and the lever 4 pushes the slider 36 to slide inward. After the lever 4 is out of contact with the slider 36, the slider 36 extends outward under the elastic force of the first spring 37. At this time, the slider 36 gradually releases the squeezing of the two second clamping blocks 38. At this time, the organ module 2 can be directly pulled out, and the second mounting block 32 is moved out of the first mounting position 11. After the organ module 2 is pulled out, the second mounting block 32 is rotated again to make the first clamping block 34 move out of the second clamping groove 22, so that the fixing device 3 and the organ module 2 can be separated, so as to replace the organ module 2.

[0040] In this embodiment, a first mounting position 11 is set on the mounting base 1, a second mounting position 21 is set on the organ module 2, and a first mounting block 31 that can be embedded in the second mounting position 21 is set on the fixing device 3, and a second mounting block 32 that can be embedded in the first mounting position 11 is set, so that the fixing device 3 and the organ module 2 can be conveniently disassembled and assembled by rotating the second mounting block 32, and the fixing device 3 and the mounting base 1 can be conveniently disassembled and assembled by moving the lever 4, thereby achieving the effect of convenient disassembly and assembly of the organ module 2. The structure is more flexible and can be adjusted according to different surgical requirements to adapt to the simulation of various surgical scenes to enhance the training effect of the model. The installation is more firm and not easy to loosen or shift, so as to ensure the accuracy and stability during the training process.

[0041] like Figure 6 As shown, in the laparoscopic ultrasonic endoscopic combined surgery training model of this embodiment, in some embodiments, the driving member is a gear 33; the shaft neck of the gear 33 is fixedly connected to the second mounting block 32; the first clamping block 34 is provided with an extension arm 341, and the extension arms 341 of the two first clamping blocks 34 are centrally symmetrically arranged; the extension arm 341 is provided with a rack structure 342; the rack structure 342 is meshed with the gear 33.

[0042] Specifically, when installing the organ module 2, the second mounting block 32 is rotated, the second mounting block 32 drives the gear 33 to rotate, the elastic energy storage component stores energy, and the gear 33 drives the two first clamping blocks 34 to slide inward through the rack structure 342, so as to embed the first mounting block 31 into the second mounting position 21, and then the second mounting block 32 is released, the elastic energy storage component releases the stored energy, and the driving gear 33 rotates in the opposite direction, thereby driving the two first clamping blocks 34 to slide outward synchronously, so that the first clamping block 34 is inserted into the second clamping groove 22, thereby realizing the installation between the fixing device 3 and the organ module 2, so that the organ module 2 is installed on the mounting base 1 through the fixing device 3.

[0043] like Figure 6As shown, in the laparoscopic ultrasound endoscopic combined surgery training model of this embodiment, in some embodiments, the elastic energy storage member is a coil spring 35; one end of the coil spring 35 is fixedly connected to the first mounting block 31; the other end of the coil spring 35 is fixedly connected to the driving member. In this embodiment, by providing the coil spring 35, when the organ module 2 is installed, the second mounting block 32 is rotated to rotate the gear 33. During the rotation of the gear 33, the coil spring 35 stores elastic potential energy. After the second mounting block 32 is released, the coil spring 35 can release the elastic potential energy, driving the gear 33 to rotate in the opposite direction, so that the first clamping block 34 can extend outward into the second clamping slot 22.

[0044] like Figure 6 As shown, in the laparoscopic ultrasonic endoscopic combined surgery training model of this embodiment, in some embodiments, a sliding hole is recessed on the side of the second mounting block 32 facing away from the first mounting block 31; the slider 36 and the first spring 37 are both arranged in the sliding hole; the bottom of the slider 36 extends out of the sliding hole under the elastic force of the first spring 37; the two second clamping blocks 38 are symmetrically distributed on both sides of the sliding hole; the side wall of the slider 36 is provided with a driving groove; the side wall of the sliding hole is provided with a locking structure; the locking structure cooperates with the driving groove to unlock the slider 36.

[0045] In this embodiment, a sliding hole is provided to facilitate the installation of the slider 36 and the first spring 37; after all the second mounting blocks 32 are placed in the first mounting position 11, the slider 36 is driven to slide inward by the slider 4 by toggling the toggle lever 4, and the first spring 37 is compressed, so that the slider 36 drives the two second clamping blocks 38 to slide outward through the inclined surface contact cooperation during the inward sliding process, until the second clamping blocks 38 are inserted into the corresponding first clamping groove 12, and at this time, the locking structure cooperates with the driving groove to lock the slider 36, so that the slider 36 keeps squeezing the two second clamping blocks 38, so that the second clamping blocks 38 remain in the state of being inserted into the first clamping groove 12, so that the organ module 2 is firmly installed on the mounting base 1, and is not easy to loosen or deviate, thereby ensuring the accuracy and stability of the organ module 2 during training;

[0046] When it is necessary to remove the organ module 2 from the mounting base 1, the lever 4 is pushed again, and the lever 4 pushes the slider 36 to slide inward, so that the locking structure cooperates with the driving groove to release the lock of the slider 36. After the lever 4 is out of contact with the slider 36, the slider 36 extends outward under the elastic force of the first spring 37, so that the slider 36 is out of contact with the two second blocks 38. At this time, the organ module 2 can be pulled out.

[0047] Further, if Figure 7As shown, the driving groove includes a first inclined section 361, a second inclined section 362, a third inclined section 363 and a fourth inclined section 364 connected end to end in sequence; a first blocking step 365 is provided between the first inclined section 361 and the fourth inclined section 364; a second blocking step 366 is provided between the second inclined section 362 and the first inclined section 361; a third blocking step 367 is provided between the third inclined section 363 and the second inclined section 362; a fourth blocking step 368 is provided between the fourth inclined section 364 and the third inclined section 363; and a locking position is formed between the third inclined section 363 and the second inclined section 362. Figure 8 and Fig. 9 As shown, the locking structure includes a locking block 321 slidably arranged on the side wall of the sliding hole; the locking block 321 is elastically floating and provided with a locking pin 322 that is movably embedded in the driving groove.

[0048] Specifically, the locking block 321 is provided with a receiving hole, and a second spring 323 is provided in the receiving hole. One end of the locking pin 322 is movable and extends into the receiving hole and abuts against the second spring 323. The second spring 323 provides elastic force for the locking pin 322 so that the locking pin 322 keeps cooperating with the driving groove. Initially, the slider 36 is in an extended state under the elastic force of the first spring 37. At this time, the slider 36 is not in contact with the two second clamping blocks 38, and the locking pin 322 is located at the end of the first inclined section 361 close to the fourth inclined section 364; after all the second mounting blocks 32 are placed in the first mounting position 11, the lever 4 is moved. After the lever 4 contacts the slider 36, the slider 36 is pushed to slide inward, that is, the slider 36 slides upward. At this time, the locking pin 322 is blocked by the first blocking step 365 and can only slide downward along the first inclined section 361 until the locking pin 322 enters from the first inclined section 361. The slider 36 is in the second inclined section 362, and the slider 36 reaches the top dead center position; then the lever 4 passes over the slider 36 and is out of contact with the slider 36, and the first spring 37 pushes the slider 36 to slide downward, and the locking pin 322 is blocked by the second blocking step 366 and can only move along the second inclined section 362, until the locking pin 322 enters the third inclined section 363 and is blocked by the third blocking step 367, and the locking pin 322 is in the locking position, thereby locking the slider 36 to keep the second clamping block 38 in the state of being inserted into the first clamping slot 12, so as to prevent the organ module 2 from loosening;

[0049] When it is necessary to remove the organ module 2 from the mounting base 1, the lever 4 is pushed again, and the lever 4 can squeeze the slider 36 to move upward again. Under the action of the third blocking step 367, the locking pin 322 can only move along the third inclined section 363 until the locking pin 322 enters the fourth inclined section 364 and is blocked by the fourth blocking step 368. After the lever 4 is disengaged from the slider 36 again, the first spring 37 pushes the slider 36 to slide downward. Under the action of the fourth blocking step 368, the locking pin 322 can only move along the fourth inclined section 364 until it returns to the first inclined section 361 and is blocked by the first blocking step 365. The slider 36 is disengaged from the second block 38, and the organ module 2 can be directly pulled out at this time.

[0050] Preferably, if Figure 6 As shown, both side walls of the slider 36 are provided with driving grooves, and both side walls of the slide hole are provided with locking structures. This arrangement makes the locking of the slider 36 more stable.

[0051] like Figure 6 and Figure 7 As shown, in the laparoscopic ultrasound-endoscopic combined surgery training model of this embodiment, in some embodiments, a conical portion 369 is provided at the bottom of the slider 36; the lever 4 contacts the conical portion 369 of the slider 36, thereby pushing the slider 36 to slide inward to overcome the elastic force of the first spring 37. In this embodiment, the conical portion 369 is provided so that the slider 36 cooperates with the lever 4 through the conical portion 369 to drive the slider 36 to slide.

[0052] like Figure 5 and Figure 6 As shown, in the laparoscopic ultrasonic endoscopic combined surgery training model of this embodiment, in some embodiments, the end of the second clamping block 38 away from the slider 36 is an arc portion 381, and the end of the second clamping block 38 close to the slider 36 is provided with an inclined surface 382; when the slider 36 is not in contact with the inclined surface 382 and the second clamping block 38 is in an extended state, the arc portion 381 is completely extended out of the second mounting block 32. Specifically, when the slider 36 slides upward, the slider 36 contacts the inclined surface 382 of the second block 38, thereby pushing the second block 38 to extend outward. When the locking pin 322 locks the slider 36, the arc portion 381 of the second block 38 is embedded in the first slot 12. When the locking pin 322 releases the lock on the slider 36, the slider 36 slides downward under the action of the first spring 37, releasing the squeeze on the second block 38 until the slider 36 is completely out of contact with the inclined surface 382 of the second block 38. At this time, the organ module 2 can be directly pulled out. During the pulling out process, the arc portion 381 of the second block 38 is squeezed to slide inward, so that the arc portion 381 automatically moves out of the first slot 12, so that the second mounting block 32 moves out of the first mounting position 11.

[0053] In the laparoscopic ultrasound-endoscopic combined surgery training model of this embodiment, in some embodiments, the first mounting block 31 and the second mounting block 32 are both polygonal structures, and the first mounting position 11 and the second mounting position 21 are both polygonal structures; this arrangement is used to limit the rotational freedom of the first mounting block 31 and the second mounting block 32 after the organ module 2 is installed, and the structure is more reliable.

[0054] like Figure 1 , Figure 2 and Fig.10 As shown, in the laparoscopic ultrasound-endoscopic combined surgery training model of this embodiment, in some embodiments, a push rod 41 is vertically extended from one end of the lever 4; a roller 42 is axially connected to the end of the push rod 41; an outer cover 5 is hingedly connected to one end of the mounting base 1; a through hole 51 is penetrated through the outer cover 5; a guide groove is recessed on one side of the outer cover 5; the guide groove includes a receiving section 521, an extrusion section 522 and a horizontal section 523 connected in sequence; and the roller 42 movably extends into the guide groove. Specifically, the mounting base 1 is provided with an avoidance hole for avoiding the push rod 41, and the push rod 41 movably penetrates the avoidance hole.

[0055] When the organ module 2 needs to be installed, the lever 4 is pushed toward the hinged end of the installation base 1, and the roller 42 rolls along the accommodating section 521, the extruding section 522, and the horizontal section 523 in sequence. When the roller 42 contacts the extruding section 522, the lever 4 pushes the outer cover 5 to open upward through the push rod 41 until the roller 42 moves to the end of the horizontal section 523 away from the extruding section 522, and then the organ module 2 is installed. After all the second installation blocks 32 are placed in the first installation position 11, the lever 4 is pushed toward the hinged end away from the installation base 1, and the roller 42 moves along the horizontal section 523. The outer cover 5 is gradually turned to the closed state. At this time, the lever 4 slides, pushing the slider 36 to slide upward, the locking structure locks the slider 36, and the arc portion 381 of the second clamping block 38 is inserted into the first clamping groove 12 until the lever 4 is out of contact with the slider 36. Then the roller 42 enters the inclined section from the horizontal section 523, and then enters the accommodating section 521 through the inclined section. At this time, the push rod 41 is accommodated in the accommodating section 521, and the outer cover 5 is covered on the mounting base 1; then the user can insert an ultrasonic endoscope or a laparoscope through the through hole 51 of the outer cover 5 to perform surgical training. With this arrangement, the outer cover 5 can be opened and closed by operating the lever 4.

[0056] In addition, when the second mounting block 32 is not installed in place, since the second clamping block 38 cannot be inserted into the first clamping groove 12, the slider 36 cannot be completely moved upward to the top dead center position, and the lever 4 cannot completely pass over the tapered portion 369 of the slider 36. At this time, the outer cover 5 cannot be completely closed. In this way, the closing condition of the outer cover 5 can be used to provide feedback on the installation condition of the organ module 2 to ensure that the organ module 2 is in a stable state during training.

[0057] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
