Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a skin tumor surgical excision device. Background Art

[0002] Skin tumors are cell proliferative diseases that occur in the skin. They are common diseases that occur in the skin or subcutaneous tissue. There are many types of skin tumors, which are clinically divided into benign tumors and malignant tumors. Malignant tumors can continue to proliferate, cause metastasis, and threaten life. They are called skin cancer. Skin tumors are a relatively difficult dermatological disease to treat.

[0003] When using existing skin tumor surgical excision devices, medical staff usually manually stretch the skin at the patient's tumor site for cutting, and then use a retractor to pull the cut site. However, when stretching the patient's skin for cutting, it is necessary to apply pressure to the patient's skin for a long time. The long-term stretching will cause the medical staff's finger and arm muscles to continue to contract to maintain the stretching force. The muscles will gradually feel sore and weak, affecting the flexibility and strength control of the fingers, making it difficult to maintain the stretching action stably, and even causing unconscious tremors, interfering with surgical operations. In addition, when using a retractor to pull the patient's skin, it is inconvenient to use different traction forces for different tissues. For this reason, we propose a skin tumor surgical excision device. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figures 1 to 8 The present invention provides a technical solution: a skin tumor surgical excision device, comprising: a placement box 1,

[0032] The device further comprises: an opening mechanism 2, which is arranged inside the placement box 1 and adjusts the opening force of the device according to the degree of lifting of the device;

[0033] The moving mechanism 3 is arranged on one side of the spreading mechanism 2, and the moving mechanism 3 adjusts the traction force of the device according to the spreading force of the device.

[0034] The opening mechanism 2 includes a support rod 201 rotatably connected to the inside of the placement box 1, one end of the support rod 201 is fixedly connected to a rotating gear 202, a movable rack 203 is meshed between the teeth of the rotating gear 202, one end of the movable rack 203 is fixedly connected to a connecting block 204, the bottom of the connecting block 204 is fixedly connected to a support frame 205, the bottom of the support frame 205 is fixedly connected to a suction cup 206, the top of the rotating gear 202 is fixedly connected to a first vertical roller 207, the surface of the first vertical roller 207 is wrapped with a connecting rope 208, the middle part of the connecting rope 208 is in contact with a limiting rod 209, the side of the connecting rope 208 close to the limiting rod 209 is wrapped with a pulley assembly 210, and the pulley assembly 210 is fixedly connected to the inside of the placement box 1.

[0035] The support rod is rotatably connected to the interior of the placement box 1, and the rotating gear 202 fixed at one end is the starting component of the transmission of the entire expansion mechanism 2. When an external force is applied to the support rod 201 to rotate, the rotating gear 202 rotates accordingly, and through engagement with the mobile rack 203, the rotational motion is converted into linear motion, thereby driving the subsequent components to move. The mobile rack 203, which is meshed between the teeth of the rotating gear 202, moves linearly under the drive of the rotating gear 202. The connecting block 204 fixed at one end of the mobile rack 203 is used to connect to the support frame 205, transmitting the linear motion of the mobile rack 203 to the support frame 205, thereby realizing the lifting and lowering of the support frame 205. The support frame 205 fixedly connected to the bottom of the connecting block 204 is the component that directly acts on the surgical site. The suction cup 206 at its bottom can be adsorbed on the skin around the surgical site, playing the role of stable support and preliminary expansion of the skin, creating conditions for subsequent surgical operations. The rotating gear 202 fixed at the bottom of the first vertical roller 207 rotates as the first vertical roller 207 rotates. The connecting rope 208 is wound around the surface of the first vertical roller 207. The change in the tension of the connecting rope 208 controls the first vertical roller 207 to be retracted and extended when the spiral spring 218 rotates, thereby adjusting the extension force of the extension mechanism 2. The limiting rod 209 that the middle part of the connecting rope 208 resists is used to limit the movement path of the connecting rope 208, ensuring that the connecting rope 208 runs stably during the retraction and extension process. The pulley assembly 210 includes a fixed pulley group and a movable pulley group. The fixed pulley group axle is fixed to one side of the inside of the placement box 1 and its position remains unchanged. The movable pulley group axle can move with the load. The connecting rope 208 passes around the pulley grooves of the fixed pulley group and the movable pulley group in a specific winding method, first passing around the pulley of the movable pulley group, and then returning to pass around the pulley of the fixed pulley group. The winding is cyclical, realizing the transmission and direction change of force. At the same time, through the labor-saving principle of the pulley group, it is convenient for medical personnel to operate and lift or move loads such as the support frame 205.

[0036] One end of the connecting rope 208 is fixedly connected to the handle 211, and the surface of the handle 211 is slidably connected to the support ring 212. The top of the support ring 212 is fixedly connected to the rotating member 213, and the surface of the rotating member 213 is slidably connected to the first support rod 214. One end of the first support rod 214 is provided with a rotating groove adapted to the rotating member 213. One end of the first support rod 214 is rotatably connected to the second support rod 215, and the middle part of the second support rod 215 is rotatably connected to the rotating rod 216. One end of the second support rod 215 is rotatably connected to the fixed rod 217, and the fixed rod 217 is fixedly connected to one side of the placement box 1.

[0037] The handle 211 fixedly connected to one end of the connecting cable 208 is a direct component for medical staff to operate the expansion mechanism 2. The support ring 212 slidably connected to the surface of the handle 211, the rotating part 213 fixedly connected to the top, and the first support rod 214, the second support rod 215, the rotating rod 216 and the fixed rod 217 slidably connected to the rotating part 213 constitute a linkage structure. Medical staff drive the connecting cable 208 to move by pushing and pulling the handle 211. By setting the connecting cable 208 inside the first support rod 214 and the second support rod 215 to move and generate tension changes, fine adjustment of the expansion force can be achieved.

[0038] A spiral spring 218 is fixedly connected to the surface of the support rod 201 , and one end of the spiral spring 218 is fixedly connected to a limiting box 219 . The limiting box 219 is fixedly connected to the inside of the placement box 1 .

[0039] The vortex spring 218 deforms when the support rod 201 rotates, storing elastic potential energy. When the external force disappears, the vortex spring 218 releases the elastic potential energy, driving the support rod 201 to reset, so that the expansion mechanism 2 returns to its initial state, which is convenient for next use.

[0040] A sliding member 4 is fixedly connected to one side of the movable rack 203 . The sliding member 4 is slidably connected to the interior of the placement box 1 . A sliding groove adapted to the sliding member 4 is provided inside the placement box 1 .

[0041] The sliding member 4 fixedly connected to one side of the mobile rack 203 is slidably connected to the slide groove opened inside the placement box 1, providing guidance and support for the linear motion of the mobile rack 203, ensuring that the mobile rack 203 is stable and reliable during the movement and avoiding deviation.

[0042] A first slot adapted to fit the connecting rope 208 is defined at the top of the support ring 212 , and a second slot adapted to fit the connecting rope 208 is defined inside both the first support rod 214 and the second support rod 215 .

[0043] The first empty slot on the top of the support ring 212 and the second empty slots inside the first support rod 214 and the second support rod 215 are used to accommodate the connecting rope 208 to ensure that the connecting rope 208 is not hindered during movement.

[0044] The moving mechanism 3 includes a force sensor 301 fixedly connected to one side of the support frame 205, one end of the force sensor 301 is fixedly connected to a rope box 302, the interior of the rope box 302 is rotatably connected to a second vertical roller 303, one end of the second vertical roller 303 is fixedly connected to a fixed motor 304, one end of the fixed motor 304 is fixedly connected to one side of the rope box 302, a steel cable 305 is wrapped around the surface of the second vertical roller 303, and a hook 306 is sleeved on one end of the steel cable 305.

[0045] The force sensor 301 fixedly connected to one side of the support frame 205 is used to monitor the size of the expansion force exerted on the support frame 205 in real time, and convert the force signal into an electrical signal and transmit it to the microcontroller 307. The fixed motor 304 fixedly connected to one side of the rope box 302 is the core component for the retraction and extension of the steel cable 305, providing power for the rotation of the second vertical roller 303. The second vertical roller 303 rotates under the drive of the fixed motor 304. The microcontroller 307 controls the fixed motor 304 to achieve precise retraction and extension of the steel cable 305, thereby adjusting the traction force. The steel cable 305 wrapped around the surface of the second vertical roller 303 has a hook 306 at one end for hooking tumor tissue or related structures of the surgical site. The retraction and extension of the steel cable 305 drives the hook 306 to pull the tumor tissue to assist in surgical operations.

[0046] A third slot adapted for the steel cable 305 is provided on one side of the rope box 302 . A microcontroller 307 is fixedly connected to the interior of the support frame 205 . A battery panel 308 is fixedly connected to the side of the support frame 205 close to the microcontroller 307 .

[0047] The third empty slot opened on one side of the rope box 302 is used for the steel cable 305 to pass through, ensuring that the steel cable 305 is smooth and unobstructed during the retraction and extension process. The microcontroller 307 fixedly connected inside the support frame 205 receives the electrical signal transmitted by the force sensor 301, and sends control instructions to the fixed motor 304 according to the preset program and algorithm, adjusts the speed and direction of the fixed motor 304, thereby realizing automatic adjustment of the traction force according to the expansion force. The battery panel 308 fixedly connected to the side of the support frame 205 close to the microcontroller 307 provides power support for components such as the microcontroller 307, the force sensor 301 and the fixed motor 304.

[0048] Example 2

[0049] like Figures 1 to 38, and the cam 906 is fixedly connected to the bottom of the second gear 905.

[0050] The connecting frame 5, support plate 6, spherical rod 7, wedge plate 8 and clamping piece 9 on one side of the box 1 constitute an adjustable auxiliary support structure. When the angle of the support plate 6 needs to be adjusted, the medical staff pushes the pushing plate 902 to move and compresses the fixing spring 901, manually rotates the support plate 6, and the wedge plate 8 is rotated around the spherical rod 7 through the rotation connection between the spherical rod 7 and the wedge plate 8. After adjusting to the appropriate angle, the pushing plate 902 is released, the fixing spring 901 resets and drives the pushing plate 902 to reset, and the clamping piece 9 inside the wedge plate 8 plays a role, the first tooth plate 903 engages with the fixed gear 904, and the fixed gear 904 drives the second tooth plate 905 to move, and the clamping rod 906 at the bottom of the second tooth plate 905 is inserted into the card groove on the surface of the spherical rod 7 to fix the wedge plate 8, thereby achieving the fixation of the angle of the support plate 6 and providing additional stable support for the surgical operation.
