Description

Technical Field

[0001] This invention relates to the field of tissue cutting technology, and in particular to a dermatological tissue cutter. Background Technology

[0002] In dermatological surgery, the scalpel is a core tool. When removing skin lesions such as cysts or moles, it is necessary to ensure complete removal while avoiding damage to the cyst and contamination. Doctors usually need to use the scalpel to precisely control the depth of removal, especially for larger cysts and other lesions, and may even need to expand the excision area to ensure complete removal.

[0003] Current dermatological lesion tissue cutters pose a risk of slipping and falling when operated by the surgeon, further increasing safety hazards. Furthermore, the surgeon's use of both hands during surgery makes it difficult to maneuver cysts and expand the surgical field. Traditional cutters lack flexibility, resulting in a long learning curve for excision and hindering wound cleaning. Therefore, this application provides a dermatological lesion tissue cutter to meet these needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dermatological lesion tissue cutter to solve the problem that existing dermatological lesion tissue cutters cannot prompt doctors to protect the blade at all times, and there is a risk of dropping the blade when doctors are holding it for cutting.

The button battery 402, buzzer 401, finger ring switch 303 and indicator switch 102 are electrically connected by wires to ensure that the blade sleeve 201 is installed in place or the finger ring 302 is put on the finger. This also prevents the indicator switch 102 from interfering with the alarm when it is not pressed during normal use of the handle 101.

[0042] like Figures 2 to 9 As shown, the actuation auxiliary component 5 includes an actuation rod 501 rotatably mounted on one side of the handle 101; a rubber pad is provided at the end of the actuation rod 501; a spring piece 502 is fixedly mounted at one end of the actuation rod 501, and the other end of the spring piece 502 is fixedly mounted on the handle 101; the spring piece 502 has a V-shaped structure; a paddle 503 is fixedly mounted at the other end of the actuation rod 501; the paddle 503 is attached to the cutting blade 105; the paddle 503 is located inside the cutting edge of the cutting blade 105, and the actuation rod 501 is used to control the paddle 503 to expand outward; a groove is provided on the paddle 503; the actuation auxiliary component 5 also includes a liquid injection hole 5031 opened on the actuation rod 501, and the liquid injection hole 5031 communicates with the groove inside the paddle 503, and the liquid injection hole 5031 and the groove are used for rinsing; the rinsing auxiliary component 6 includes a liquid injection tube 601 fixedly mounted on the actuation rod 501; the liquid injection tube 601 is connected to The device includes an injection port 5031 and an injection tube 601 with a fixed end connector 602. The tube end connector 602 is connected to a saline pump via a flexible tube, and the saline pump is connected to a saline tank. The irrigation aid 6 has a compact structure and is suitable for cutting and irrigating subcutaneous cysts. When the cutting location is deep, the device can assist in moving the side of the cyst using a pry bar 503 to widen the surgical field and facilitate confirmation of the cutting location. The device has a simple structure and operation, improving its functionality. The surgeon can perform other surgical operations with their other hand, such as hemostasis and debridement. The injection port 5031 facilitates water irrigation of the wound, and the pry bar 503 can be used to adjust the irrigation position. During the cutting process, the pry bar 501 can be pressed to squeeze the spring 502. At this time, the rotation of the pry bar 501 can drive the pry bar 503 to expand outward, assisting in moving the wound and increasing the surgical field.

[0043] The workflow of the technical solution of this invention is as follows:

[0044] First, the scalpel handle 101 can be held directly to cut the diseased tissue using the cutting blade 105. When cutting is complete or paused, the blade sleeve 201 can be placed over the cutting blade 105, and the indicator switch 102 can be pressed against the end of the plastic connecting piece 202. To resume cutting, the blade sleeve 201 can be removed by manually pulling outwards on the handle plate 203. At this point, the end of the plastic connecting piece 202 will no longer press against the indicator switch 102, and the corresponding buzzer 401 will be activated, sounding an alarm. However, at this time, the finger ring 302 can be fitted onto the finger. When the end of switch 303 is pressed against the finger, the finger switch 303 is pressed, the buzzer 401 is de-energized, and there will be no buzzing interference. This ensures that when the doctor uses the scalpel handle 101, it can be connected by the anti-slip rope 301 to prevent it from falling off. The structure is simple and reasonable. During the cutting process, the lever 501 can be pressed to squeeze the spring 502. At this time, the lever 501 rotates and drives the scalpel 503 to expand outward, which helps to move the wound and increase the surgical field. At the same time, when irrigation is needed, the water pump connected to the tube end connector 602 can be started. Water is supplied through the injection hole 5031 and then discharged in the groove of the scalpel 503 to help irrigate the wound.
