Description

Technical Field

[0001] The present invention relates to the technical field of mastoscopic surgery training, and more specifically, to a training device for simulating mastoscopic surgery. Background Art

[0002] Mastoscopes are used to treat breast diseases, which is characterized by minimal trauma, preservation of function and cosmetic appearance, less bleeding, and quick recovery. Mastoscopes are used to clear axillary lymph nodes and internal mammary lymph nodes, reduce complications, and improve the quality of life of patients. The surgical methods cover almost all aspects of breast surgery.

[0003] The doctor will make a 0.5-1 cm incision on the skin about 3-4 cm away from the lesion under local or general anesthesia. Then insert the dilator into the incision and push it to the vicinity of the lesion along the catheter or under ultrasound guidance. Then inject saline or carbon dioxide gas through the dilator to expand the internal space of the breast, and insert the working channel into the dilator. Finally, insert the laparoscope into the working channel, and the surgical field can be observed on the monitor. Depending on the purpose, the doctor will choose the appropriate surgical instrument for diagnosis or treatment. After the operation is completed, the surgical instrument, laparoscope, working channel and dilator are pulled out in turn, and the incision is sutured.

[0004] The above process is relatively difficult. In order to ensure the success rate of the operation, the surgeon needs to have a high level of surgical proficiency. Therefore, it is particularly important to conduct laparoscopic surgery training. During the doctor's training, prostheses are usually used as surgical training objects. When prostheses are consumables, in order to save materials, the prostheses will be processed relatively thin. When the doctor makes an error in the training operation, the scalpel will pierce through the prosthetic breast cavity and contact the receiving plate under the prosthesis, causing the prosthesis heated and melted by the scalpel to stick to the receiving plate. When the prosthesis is removed from the receiving plate after the training is completed, the part of the prosthesis that is stuck to the receiving plate will be torn, and the torn small pieces of the prosthesis will adhere to the receiving plate. When the new prosthesis is subsequently placed on the receiving plate, the small pieces of the prosthesis remaining on the receiving plate will lift up the new prosthesis, causing the doctor to misjudge the position of various parts of the new prosthesis, thereby greatly reducing the training effect. Summary of the invention

[0005] The present invention provides a training device for simulating mastoscopic surgery, which aims to overcome the disadvantage that small pieces of prosthesis remaining on a receiving plate will lift up the new prosthesis, causing doctors to misjudge the positions of various parts of the new prosthesis, thereby greatly reducing the training effect.

DETAILED DESCRIPTION

[0033] The support block 2 is made of rust-proof material to prevent the support block 2 from rusting and affecting the fit of the prosthesis 3.

[0035] The driving assembly includes an electric slide rail 205 and an electric slider 206; two electric slide rails 205 are bolted to the support block 2; each electric slide rail 205 is slidably connected to an electric slider 206, and the electric slider 206 is fixedly connected to the right connecting plate 201.

[0036] It also includes a protection component; the fixed block 202 is connected with a protection component; the protection component includes a U-shaped block 207, a connecting rod 208, a rack 1 209, a round rod 1 2010, a spur gear 2011, a rack 2 2012, a round rod 2 213, a long rod 214 and a spring 2 215; two U-shaped blocks 207 are bolted to the right connecting plate 201, and the U-shaped block 207 is set to an alloy material; two connecting rods 208 are slidably connected to the right fixed block 202, and the connecting rods 208 are bolted to the corresponding U-shaped blocks 207; each connecting rod 208 is fixed with a rack 1 209; two round rods are rotatably connected to the right fixed block 202. Rod 1 2010; each round rod 1 2010 is fixedly connected with a spur gear 2011, which meshes with the corresponding rack 1 209; each spur gear 2011 is meshed with a rack 2012; all racks 2012 are fixedly connected with a long rod 2014; two round rods 2013 are slidably connected to the long rod 2014, and the round rods 2013 are welded with the corresponding fixed blocks 202; each round rod 2013 is sleeved with a spring 2 2015, one end of the spring 2 2015 is fixedly connected to the corresponding fixed block 202, and the other end of the spring 2 2015 is fixedly connected to the long rod 2014; the long rod 2014 is bolted to the scraper 4.

[0037] First, the doctor conducts laparoscopic surgery training with the prosthesis 3 as the object. When the scalpel passes through the prosthesis 3 and contacts the support block 2, the area around the puncture hole of the prosthesis 3 is melted by the scalpel, so that the puncture hole of the prosthesis 3 is adhered to the surface of the support block 2. After the training is completed, the fixed block 202 is manually pulled upward, and the fixed block 202 drives the connecting block 203 to move upward, and compresses the spring 204, so that the fixed block 202 stops pressing the prosthesis 3, and then the prosthesis 3 is manually removed from the support block 2. During this process, the part around the puncture hole of the prosthesis 3 will be torn and adhere to the support block 2, and then the fixed block 202 is manually stopped, and the spring 204 rebounds to drive the connecting block 203 to move downward, and the connecting block 203 drives the fixed block 202 to move downward, and the fixed block 202 drives the scraper 4 to move downward and contact the support block 2, and the electric slide rail 205 and the electric The slider 206, the electric slider 206 drives the right connecting plate 201 to slide to the left, and the connecting plate 201 drives the parts thereon to move to the left, so that the fixed block 202 drives the scraper 4 to move to the left, so that the impurities remaining on the surface of the support block 2 are scraped off by the scraper 4. At the same time, after the position of the right fixed block 202 is changed by the electric slider 206, the distance between the two fixed blocks 202 changes, so that the prosthesis 3 of different lengths can be clamped and fixed, which is beneficial to improve universality. When in use, the distance between the two fixed blocks 202 can be adjusted according to the length of the prosthesis 3, so that the prosthesis 3 of different lengths can be clamped and fixed. When the fixed block 202 adjusts the distance, it can also drive the scraper 4 to move to the left, and scrape off the impurities remaining on the surface of the support block 2, thereby avoiding the problem that the impurities lift up the new prosthesis 3 and affect the training effect.

[0038] When the fixed block 202 presses and fixes the prosthesis 3, the scraper 4 should be set on the inner side of the fixed block 202 to prevent the scraper 4 from being damaged due to long-term pressure, and to prevent the scraper 4 from crushing the prosthesis 3. When the prosthesis 3 is taken out and prepared for cleaning, the spring 1 204 rebounds and drives the connecting block 203 to move downward, and the connecting block 203 drives the fixed block 202 to move downward. Since the U-shaped block 207, the connecting rod 208 and the rack 1 209 remain prohibited, the fixed block 202 drives the round rod 1 2010 and the spur gear 2011 to roll on the rack 1 209, so that the spur gear 2011 drives the rack 2 2012 to move downward, and the rack 2 2012 drives the long rod 2014 to slide downward on the round rod 2 2013 The long rod 2014 drives the scraper 4 to move downward, so that the scraper 4 is away from the inner side of the fixed block 202 and contacts with the support block 2, and then the electric slide rail 205 and the electric slider 206 are started, so that the connecting plate 201 drives the parts thereon to move to the left, thereby causing the scraper 4 to move to the left to scrape off the impurities remaining on the upper side of the support block 2. When in use, the scraper 4 is set on the inner side of the fixed block 202 to avoid the prosthesis 3 and the scraper 4 from being crushed. At the same time, the person only needs to stop tightening the fixed block 202, and the scraper 4 can be linked to contact the support block 2 downward through the downward pressure of the fixed block 202, and then the scraping and cleaning operation can be performed. The structure is ingenious and the operation is convenient.

[0039] Implementation 2

[0040] Based on Implementation Plan 1, Figure 1 , Figure 2 and Figure 7 As shown, it also includes an auxiliary component; the auxiliary component is connected to the support block 2; the auxiliary component includes a connecting frame 2016 and a limiting strip 2017; a connecting frame 2016 is bolted to both sides of the support block 2, and the connecting frame 2016 is set to a plastic material; each connecting frame 2016 is bolted to a limiting strip 2017, and the connecting block 203 is limited by the limiting strip 2017 to prevent the scraper 4 from moving upward over the stubborn impurities when encountering stubborn impurities, thereby avoiding the problem of incomplete cleaning.

[0041] The cross section of the limiting strip 2017 is set to be U-shaped; a chamfer is provided on the limiting strip 2017 to make it easier for the connecting block 203 to move to the inside of the limiting strip 2017.

[0042] Since the scraper 4 is pressed against the support block 2 by the elastic force of the spring 204, when the scraper 4 passes through the stubborn impurities, the scraper 4 will be pushed up by the impurities, resulting in incomplete cleaning. Therefore, when the manual tightening of the fixed block 202 is stopped, the scraper 4 moves downward to contact the support block 2. At this time, the connecting block 203 moves downward to align with the groove of the limit bar 2017, and then the electric slider 206 drives the connecting plate 201 and the parts thereon to move to the left, so that the connecting block 203 moves to the groove of the limit bar 2017. When the scraper 4 contacts stubborn impurities, the connection block 203 is blocked and limited by the limit bar 2017, thereby preventing the fixed block 202 and the parts thereon from moving up and down, thereby preventing impurities from lifting the scraper 4, thereby avoiding the problem of incomplete cleaning. When in use, the connection block 203 is limited by the limit bar 2017, thereby preventing stubborn impurities from lifting the scraper 4, thereby avoiding the problem of incomplete cleaning caused by the scraper 4 being lifted by stubborn impurities.

[0043] Implementation 3

[0044] Based on Implementation Plan 2, Figure 1 , Figure 2 and Figure 8 As shown, it also includes convex strips 2018; each fixing block 202 is fixed with a plurality of convex strips 2018, so that it is easier for a person to apply an upward pulling force to the fixing block 202, and thus it is easier to pull the fixing block 202 upward.

[0045] It also includes a support block 2019; the support block 2019 is connected to the support block 1 2 in a damping sliding manner.

[0046] It also includes a shift block 2020; the shift block 2020 is welded on the support block 2019, making it easier for humans to apply thrust to the support block 2019, and thus easier to drive the shift block 2020 to move left and right.

[0047] The convex strip 2018 is made of rubber material to facilitate manual grip.

[0048] When manually pulling the fixing block 202, the fingers pinch the convex strip 2018 to apply upward pulling force, thereby making it easier to pull up the fixing block 202, which is conducive to improving convenience.

[0049] When surgical training is stopped for a long time, the prosthesis 3 should be removed, and then the shift block 2020 should be manually pushed to move to the left. The shift block 2020 drives the support block 2019 to move to the left, so that the support block 2019 slides to the lower side of the right fixed block 202, and then the pulling of the fixed block 202 is manually stopped. At this time, the right fixed block 202 is supported by the support block 2019 to prevent the fixed block 202 from moving downward and linking the scraper 4 to contact the support block 2, thereby preventing the end of the scraper 4 from being pressed against the support block 2 for a long time and causing the end to be damaged.

[0050] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
