Description

Technical Field

[0001] This invention relates to the field of medical surgical instruments, and more particularly to a breast surgical retractor that can prevent skin burns. Background Technology

[0002] Surgical retractors are medical instruments used in surgical procedures to retract skin tissue, allowing doctors to better observe and manipulate the surgical area. Surgical retractors are typically made of corrosion-resistant metal. However, during surgery, high-frequency electrosurgical units are often used to cut the skin. While these units can stop bleeding through the incision using high-frequency current, the current can also easily come into contact with the metal retractor, causing high temperatures and potentially burning the skin around the incision, leaving scars. Therefore, for breast surgeries, where scarring must be avoided, a surgical retractor that prevents skin burns is necessary for successful procedures.

[0003] For example, CN202420837066.5 proposes a breast surgery anti-scalding hook buckle, which includes an expansion mechanism and a transmission locking mechanism. The expansion mechanism is used to expand the surgical incision, and the top of the expansion mechanism is provided with a transmission locking mechanism to lock the expansion mechanism. The expansion mechanism includes a first crossbar, a second crossbar, an extension component, and a hook component. The second crossbar is mirrored on one side of the first crossbar. The extension component includes a first shaft, a first connecting rod, a second shaft, a third shaft, and a second connecting rod. The first shaft is fixedly connected to both ends of the first crossbar. This utility model provides a breast surgery anti-scalding hook buckle. By setting an expansion mechanism, after the breast incision is completed, the buckle is extended to the lower layer of skin, and the incision can be expanded by simultaneously pulling the first and second crossbars to both sides, thereby achieving the purpose of wound expansion. However, it only reduces contact with the electrocautery knife by expanding the wound, thus avoiding skin burns. It is not suitable for minimally invasive surgeries such as breast surgery and does not completely solve the above problems.

[0004] The present invention can isolate the metal hook from the cut by means of a heat insulation device, thereby avoiding skin burns. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 - Figure 11 This invention provides a technical solution: a breast surgery retractor that can prevent skin burns includes a first slider 5, a connecting block 6, and a heat dissipation plate 7. The connecting block 6 is fixed to the first slider 5, and the heat dissipation plate 7 is fixed to the connecting block 6. The heat dissipation plate 7 has an arc-shaped structure, which can better fit the incision and ensure the traction effect of the retractor. The lower part of the heat dissipation plate 7 has a hook-shaped protrusion, and the heat dissipation plate 7 has uniformly elongated vertical through holes. The connecting block 6 is made of insulating material, and a baffle 8 is provided at the front end of the connecting block 6. The baffle 8 is located in front of the heat dissipation plate 7. A gap is left between the baffle 8 and the heat sink 7. The baffle 8 has an arc-shaped structure and a frosted surface to reduce reflection, thereby providing a better field of vision at the incision site. It also blocks the vertical through-hole structure of the heat sink 7 to avoid glare. The upper end of the connecting block 6 is equipped with a rotating cold light lamp 9, which has an interface for connecting an optical fiber. The connecting block 6 is fixed with a suction device 10. The lower end of the suction device 10 is located between the heat sink 7 and the baffle 8 to suction away the tissue fluid secreted from the incision. The upper end of the suction device 10 has an interface for connecting a negative pressure pump.

[0025] In a specific embodiment: the heat sink 7 extends into the incision, and hooks the skin through the hook-shaped protrusion at the lower end of the heat sink 7, thereby pulling the incision. At the same time, the baffle 8 prevents the electrosurgical unit from contacting the heat sink 7, and the baffle 8 can also prevent heat from being conducted to the heat sink 7, thereby avoiding skin burns. Meanwhile, the suction device 10 is connected to a negative pressure pump to generate negative pressure, sucking away the tissue fluid secreted from the incision and driving airflow to dissipate heat from the incision through the evenly distributed vertical through holes on the heat sink 7, thereby preventing low-temperature burns caused by the incision not being dissipated in time.

[0026] like Figure 1 and Figure 2As shown, the breast surgery retractor that can avoid skin burns includes a fixation device. The fixation device includes a first slide rail 1, a support rod 2, a limiter 3, and a pressure plate 4. The first slide rail 1 is slidably connected to the first slider 5 and is equipped with bolts for adjustment and fixation. The support rod 2 is located at both ends of the first slide rail 1. One end of the support rod 2 is rotatably installed below the first slide rail 1, and the other end of the support rod 2 is rotatably installed below the first slide rail 1 and slidably connected to the first slide rail 1, and is equipped with bolts for adjustment and fixation. The limiter 3 is slidably located at the lower end of the support rod 2 and is equipped with bolts for adjustment and fixation. The pressure plate 4 is located inside the limiter 3 and is equipped with bolts for adjustment.

[0027] In a specific embodiment: during use, the limiter 3 is locked onto the edge of the operating table, and the pressure plate 4 is adjusted by bolts to fix the limiter 3 to the edge of the operating table. At the same time, the angle of the first slide rail 1 is changed by rotating and adjusting the position of the support rod 2, thereby adjusting the position and angle of the heat dissipation plate 7.

[0028] like Figure 2 , Figure 5 and Figure 6 As shown, the breast surgery retractor that can prevent skin burns includes an auxiliary device. This device includes a second slider 11, a second slide rail 12, a third slide rail 13, and a first auxiliary retractor assembly 17. The second slider 11 is slidably mounted on a fixing device and is mounted on the operating table via the fixing device. The second slide rail 12 is mounted on the second slider 11. The third slide rail 13 is rotatably mounted at both ends of the second slide rail 12. The first auxiliary retractor assembly 17 is slidably mounted on the second slide rail 12 and is equipped with bolts for adjustment and fixation. The third slide rail 13 has a zigzag structure, and a third slider 24 is provided at the end of the third slide rail 13. The upper end of the third slider 24 is slidably connected to the third slide rail 13. The lower end of block 24 is slidably connected to the first slide rail 1 and is provided with bolts for adjustment and fixation. The upper end of the third slider 24 is rotatably connected to the lower end of the third slider 24. The first auxiliary hook assembly 17 consists of mounting block 14, hook body 15 and locking block 16. The upper end of mounting block 14 is slidably mounted on the second slide rail 12. Hook body 15 is slidably mounted on the lower end of mounting block 14. Locking block 16 is rotatably mounted on the lower end of mounting block 14 and located to the side of hook body 15. Locking block 16 is provided with a spring connected to mounting block 14. Hook body 15 and locking block 16 are provided with ratchet teeth. Locking block 16 limits hook body 15 through ratchet teeth. The rear end of hook body 15 is provided with a ring structure. The rear end of the ring structure is provided with a handle for easy pulling of hook body 15.

[0029] In a specific embodiment: during use, the position of the first auxiliary hook assembly 17 is adjusted by moving the mounting block 14 and fixed by bolts. The front end of the hook body 15 extends into the cut, thereby cooperating with the heat sink 7 to pull the cut. When pulling, the hook body 15 is pulled by the annular structure and handle at the rear end of the hook body 15, thereby causing the hook body 15 to push the locking plate through the ratchet and compress the spring. After the hook body 15 is in place, the locking plate is locked by the spring's reset to prevent the hook body 15 from loosening.

[0030] like Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the breast surgical retractor that can prevent skin burns includes an isolation device. The isolation device includes a second auxiliary retractor assembly 18, a traction rod 19, a lever 20, a sleeve 21, a connecting rod 22, and a diaphragm 23. The second auxiliary retractor assembly 18 is mounted on a third slide rail 13. The second auxiliary retractor assembly 18 has the same structure as the first auxiliary retractor assembly 17. The traction rod 19 is slidably mounted on the second auxiliary retractor assembly 18. The lever 20 is rotatably mounted on the second auxiliary retractor assembly 18. A connecting rod 22 is provided between the lever 20 and the second auxiliary retractor assembly 18. Figure 9 As shown, the hinge point between the pull rod 19 and the connecting rod 22 is located in the middle of the second auxiliary hook assembly 18, the hinge point between the lever 20 and the second auxiliary hook assembly 18 is located on the outside of the second auxiliary hook assembly 18, the hinge point between the connecting rod 22 and the lever 20 is located between the first two hinge points, the sleeve 21 is rotatably mounted at the end of the pull rod 19, a torsion spring is provided between the sleeve 21 and the pull rod 19, the diaphragm 23 is wound around the sleeve 21, and a notch is opened on the pull rod 19.

[0031] In a specific embodiment: during use, the release lever 20 is rotated to unlock the pull rod 19 and allow it to slide forward. The position of the second auxiliary hook assembly 18 is adjusted by moving the mounting block 14 and fixed with bolts. The front end of the hook body 15 extends into the notch and moves with the pull of the second auxiliary hook assembly 18, thereby unfolding the diaphragm 23 wrapped around the sleeve 21 and deforming the torsion spring. After the second auxiliary hook assembly 18 is pulled into place, the lever 20 is rotated to make the lever 20 fit against the second auxiliary hook assembly 18, thereby moving the pull rod 19 backward and locking it. The pull rod 19 pushes the sleeve 21 to fit tightly against the second auxiliary hook assembly 18, and at the same time, the notch of the pull rod 19 fits tightly against the sleeve 21, thereby misaligning the center of the pull rod 19 with that of the sleeve 21, thus preventing the sleeve 21 from rotating and locking the diaphragm 23.

[0032] Working principle: In use, the limiter 3 is locked onto the edge of the operating table, and the pressure plate 4 is adjusted by bolts to fix the limiter 3 to the edge of the operating table. At the same time, the angle of the first slide rail 1 is changed by rotating and adjusting the position of the support rod 2. Then, the heat dissipation plate 7 is inserted into the incision, and the skin is hooked by the hook-shaped protrusion at the lower end of the heat dissipation plate 7. Then, the release block 20 is rotated to unlock the traction rod 19 and slide it forward. The position of the second auxiliary hook assembly 18 is adjusted by moving the mounting block 14 and fixed by bolts. The front end of the hook body 15 is inserted into the incision and moves with the traction of the second auxiliary hook assembly 18, thereby unfolding the diaphragm 23 wrapped around the sleeve 21 and deforming the torsion spring. After the second auxiliary hook assembly 18 is pulled into place, the block 20 is rotated to make the block 20 fit against the second auxiliary hook assembly. 18. This causes the pull rod 19 to move backward and lock, and pushes the sleeve 21 to press against the second auxiliary hook assembly 18. At the same time, the notch of the pull rod 19 presses against the sleeve 21, thus misaligning the center of the pull rod 19 with that of the sleeve 21, thereby preventing the sleeve 21 from rotating and locking the diaphragm 23. The position of the first auxiliary hook assembly 17 is adjusted by the movable mounting block 14 and fixed by bolts. The front end of the hook body 15 extends into the cut, thereby cooperating with the heat sink 7 to pull the cut. At the same time, the front end of the hook body 15 hooks the diaphragm 23. Then, the hook body 15 is pulled by the annular structure and handle at the rear end of the hook body 15, thereby causing the hook body 15 to push the locking plate through the ratchet and compress the spring. After the hook body 15 is in place, the spring returns and pushes the locking plate to lock the hook body 15, preventing the hook body 15 from loosening. After being pulled into place, the baffle 8 will prevent the electrosurgical knife from contacting the heat sink 7. The baffle 8 can also prevent heat from being conducted to the heat sink 7, thus avoiding skin burns. At the same time, the suction device 10 is connected to a negative pressure pump to generate negative pressure, sucking away the tissue fluid secreted from the incision and driving airflow to dissipate heat from the incision through the evenly distributed vertical through holes on the heat sink 7, thereby preventing low-temperature burns caused by the incision not being dissipated in time. Meanwhile, the front end of the first auxiliary hook assembly 17 hooks the diaphragm 23 to avoid direct contact with the skin and thus avoid burns. Furthermore, since the sleeve 21 at the front end of the second auxiliary hook assembly 18 is equipped with a diaphragm 23, it also prevents the electrosurgical knife from contacting the second auxiliary hook assembly 18, thus preventing the electrosurgical knife from conducting electric heating to the second auxiliary hook assembly 18.
