Description

Technical Field

[0001] The present invention relates to the technical field of skin sampling, and in particular to a skin sampling device. Background Art

[0002] The skin is the largest organ in the body, and its subtle changes are closely related to external stimuli and visceral diseases. No matter what disease you have, as long as skin symptoms appear, you should go to the dermatology department immediately. Combining the visible and touchable skin lesions such as skin erythema, papules, nodules, blisters, wheals, scales, erosions or lichens that appear on the skin, mucous membranes, nails, hair, etc., combined with clinical symptoms such as itching, numbness, and pain, dermatologists can usually diagnose the disease based on previous clinical experience, and carry out symptomatic treatment and treatment. However, for some patients who are difficult to diagnose with the naked eye or differential diagnosis, and for patients with stubborn, recurrent or conventional treatment ineffective diseases, a small amount of diseased skin is usually removed for pathological biopsy to obtain an accurate diagnosis of the disease, thereby avoiding delays in the disease and allowing patients to receive more accurate treatment.

[0003] In routine biopsy excision, we currently do not have a unified standard for the size of skin lesion excision. Especially for exposed skin areas such as the face, neck or limbs, the healing of the skin after skin lesion excision and the risk of postoperative scars should be fully considered clinically. If the skin lesion is excised too small or the excision depth is not enough, it may affect the accuracy of the pathological results; if the skin lesion is excised too large or too deep, it may increase the amount of bleeding, affect the patient's postoperative wound repair and increase the risk of scars. Therefore, we urgently need a new device for sampling lesion skin in clinical practice to overcome the shortcomings and application limitations of traditional skin sampling, reduce the pain and discomfort of patients during the sampling process, improve patient compliance, and enable clinicians to collect patients' lesion skin samples more quickly, conveniently and accurately, which will greatly improve the accuracy of disease diagnosis and enable patients to receive more effective and accurate treatment.

[0004] A skin sampling device is disclosed with publication number CN117838205B, including a shell and a propulsion unit, a cutting unit and a spiral part arranged in the shell. The propulsion unit includes a screw rod, a sleeve sleeved on the screw rod and a rotating part driving the screw rod to rotate. The screw rod is slidably connected to the sleeve. The spiral part includes a screw rod with an "I"-shaped cross-section and a limiting rod fixedly connected to the screw rod. The cutting unit includes a spiral block rotatably connected to the propulsion unit and a cutting knife. The spiral block is provided with a spiral groove and is slidably connected to the spiral rod. The spiral block is rotatably connected to the end of the sleeve. The sleeve is circumferentially provided with a plurality of first sliding grooves. The limiting rod passes through the first sliding groove and is connected to the shell. The bottom of the shell is pressed on the skin. The rotating part rotates to drive the sleeve to slide to cut off the skin drilled by the cutting knife, so as to provide a skin sampling device for clinical dermatology that is easy to operate, has low operating difficulty and good effect.

[0005] The device performs skin cutting and sampling by rotating the sleeve. The skin on the human body surface generally does not fall off directly after being cut by the rotating cylinder. If the human skin is injured by external force such as rotating cylinder cutting, the following situations usually occur:

[0006] First of all, the skin has a certain elasticity and toughness. When it is subjected to cutting force, it may be damaged or cracked first. However, due to the connection between the skin and body tissues, such as subcutaneous fat and muscles, as well as the structural characteristics of the skin itself, it will not fall off directly easily.

[0007] Secondly, when the human body is injured, a series of physiological reactions will be initiated. For example, the blood will quickly coagulate at the wound to form a blood clot, which will prevent the skin from falling off to a certain extent. At the same time, the body's immune system will start to work, and white blood cells will gather at the wound to fight possible infections, further affecting the condition of the skin.

[0008] However, if the cutting force is very large and lasts for a long time, severely damaging the connection between the skin and body tissues, and is accompanied by other complex conditions, such as severe external pulling, then in extreme cases the skin may be partially or completely separated from the body, but this situation is relatively rare and usually occurs in extremely serious accidents;

[0009] In summary, under normal circumstances, the skin on the surface of the human body will not fall off directly after being cut by the rotating cylinder, so this device provides a skin sampling device. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0041] The device presses and covers the sleeve 14 on the desired sampling skin, and several auxiliary protection blocks 63 are also pressed on the skin and equidistantly surrounded by the center of the sleeve 14. At this time, the inside of the sleeve 14 and the corresponding auxiliary protection block 63 are the skin cutting sampling position. After starting the drive motor 31 and the electric cylinder 41, it will drive several cutting knives 22 to move downward under the premise of rotating in a circle to achieve skin cutting sampling operation. Because the skin has a certain elasticity and toughness, it may be damaged or cracked when subjected to cutting force. However, due to the connection between the skin and body tissues, such as subcutaneous fat, muscle, etc., as well as the structural characteristics of the skin itself, it will not fall directly and easily. At the same time, while the several cutting knives 22 move downward, the angles will continue to change, and the angles will continue to decrease. The decrease in the angles of the several cutting knives 22 will eventually cause the several cutting knives 22 to move toward the corresponding auxiliary protection block 63. Finally, when the several cutting knives 22 come into contact with the corresponding auxiliary protection block 63, the skin and tissue will be cut and peeled off to achieve effective and accurate skin cutting sampling operation.

The taking method and the operation and cutting start of the device are relatively convenient, and the skin sampling and cutting device that is easy to take manually allows medical staff to better control the contact position between the device and the skin. The device can accurately locate the sampling area. When taking skin samples, for example, to diagnose skin diseases such as melanoma and skin inflammation, samples need to be obtained from specific lesions. Medical staff can accurately place the cutting device in the target area by hand feeling and visual feedback to avoid taking irrelevant tissues, thereby ensuring that the obtained samples can accurately reflect the lesion and improve the accuracy of diagnosis. Different patients have different physical conditions such as obesity, muscle tension, and skin relaxation.

The driving wheel 32 rotates and drives the driven wheel 33 to rotate through the cooperation of the belt 34. The driven wheel 33 rotates and drives the two rotating rods 35 to rotate. The two rotating rods 35 rotate and drive the rotating cylinder 36 to rotate on the inner wall of the sleeve 14, thereby driving the lifting and adjusting device 4 to rotate, and finally driving the several cutting devices 2 on the lifting and adjusting device 4 to rotate, so as to realize the rotary cutting operation.

At this time, the inside of the sleeve 14 and the corresponding auxiliary protection block 63 are the skin cutting sampling positions, and after starting the driving motor 31 and the electric cylinder 41, it will drive a number of cutting knives 22 to move downward under the premise of rotating around to achieve skin cutting sampling operations, Because the skin has a certain elasticity and toughness, it may be damaged or cracked first when subjected to cutting force. However, due to the connection between the skin and body tissues, such as subcutaneous fat, muscles, etc., as well as the structural characteristics of the skin itself, it will not fall off directly. At the same time, the angles of the several cutting knives 22 will continue to change while moving downward, and the angles will continue to decrease. The decrease in the angles of the several cutting knives 22 will eventually cause the several cutting knives 22 to move toward the corresponding auxiliary protective blocks 63, and finally when the several cutting knives 22 come into contact with the corresponding auxiliary protective blocks 63, the skin and tissue will be cut and peeled off, thereby achieving effective and precise skin cutting and sampling operations.

[0048] Preferably, several of the cutting devices 2 include a fixing bolt 21 and a cutting tool 22, the cutting tool 22 is provided with a fixing hole, two of the fixing bolts 21 are provided, several of the adjusting plates 55 are symmetrically provided with several threaded holes 56, several of the threaded holes 56 are divided into several groups and are evenly arranged and distributed, the cutting tool 22 is fixed to the corresponding adjusting plate 55 by two fixing bolts 21, the two fixing bolts 21 and the corresponding threaded holes 56 are adapted to be threadedly connected, several of the cutting tools 22 are provided with sensors, the auxiliary protection device 6 includes an auxiliary protection column 61, a spring 62 and an auxiliary protection block 63, the auxiliary The protective column 61 is arranged at the lower end of the auxiliary cylinder 16, and the auxiliary protective blocks 63 are provided in a plurality, and the plurality of auxiliary protective blocks 63 are equidistantly surrounded on the outer side of the auxiliary protective column 61, and the springs 62 are provided in a plurality, and the plurality of auxiliary protective blocks 63 are respectively connected to the outer side of the auxiliary protective column 61 by the corresponding springs 62, and the outer side of the plurality of auxiliary protective blocks 63 is provided with a rubber layer, and the lowest end of the lower end of the plurality of auxiliary protective blocks 63 is in the same height as the lowest end of the lower end of the sleeve 14, and the start button 7 of the electric cylinder 41 and the drive motor 31 is arranged on the side end of the storage block 13, and the electric cylinder 41 and the drive motor 31 are electrically connected to the sensor;

[0049] Sensors are provided on several cutting knives 22. When several cutting knives 22 come into contact with the corresponding auxiliary protection blocks 63, the driving motor 31 and the electric cylinder 41 stop running.

The sensor model of this device can be the relevant sensors in the Meixinsheng MT3102, the German Micro-Epsilon Miyi OptoNCDT2300BL series, and the Crescent Italian Skin-SP skin tester, which can display the detection distance through Bluetooth connection;

[0050] After cutting is achieved by contacting a plurality of cutting tools 22 with the corresponding auxiliary protective blocks 63, the cut and sampled skin is sampled in a ring state, and when the cutting tool 22 does not move upward to break contact with the corresponding auxiliary protective block 63, the cut and sampled skin will not fall out of the device, so no pollution will be caused. During subsequent sampling, the cut skin will be dropped out and taken out only after the electric cylinder 41 drives a plurality of cutting tools 22 to move upward, thereby reducing the risk of infection transmission and preventing the spread of microorganisms: if the skin does not fall after cutting, it can effectively prevent various microorganisms carried on the skin surface, such as bacteria, viruses, and fungi, from spreading in the surrounding environment. For example, in a hospital operating room or dressing room, if the tissue does not fall off after the patient's skin is cut, pathogens on the skin, such as Staphylococcus aureus, will not be contaminated onto the operating table, instruments or medical staff, thereby reducing the possibility of cross-infection. It is especially important to reduce the risk of infection for patients with low immunity. It also reduces medical-induced infections: During medical operations, such as biopsy or wound debridement, the tissue does not fall off after skin cutting to avoid it becoming a new source of infection. If tissue fragments accidentally fall into the wound, it may trigger an inflammatory response, delay wound healing, and even cause serious infection. Keeping the cut skin in place can reduce the risk of medical-induced infections. Ensure the safety of patients during treatment, ensure the quality of wound healing, and maintain the integrity of wound edges: When the skin does not fall off after cutting, the wound edge can remain relatively intact, which is critical for the initial healing of the wound, because the intact wound edge is conducive to cell migration and tissue regeneration. For example, during skin suture surgery, the skin that has not fallen off can be better aligned, making the suture process smoother, promoting the primary healing of the wound, reducing the possibility of scar formation, and protecting internal tissues from external stimuli: The intact cut skin can serve as a natural barrier to protect the tissues inside the wound from dust, chemicals and other pollutants in the external environment. During the wound healing process, internal tissues need a relatively stable and clean environment for repair. Preventing skin from falling off helps maintain this good healing environment, while ensuring sample integrity and accuracy. If it is used for testing, it can improve test reliability: If the skin is cut for pathological examination or other laboratory tests, the integrity of the sample can be ensured by not falling off the skin after cutting. For example, in a skin biopsy, the complete sample can more accurately reflect the range, depth and tissue structure characteristics of the lesion. Dermatologists can diagnose diseases more accurately by performing microscopic examinations on intact skin samples, such as determining whether it is skin cancer, inflammatory skin diseases, etc., thereby improving the accuracy and reliability of the diagnosis.

[0051] The operator of the device can hold the device to operate and change the angle of several cutting tools 22 to produce the effect;

[0052] Improve operational accuracy

[0053] Precisely locate the sampling area: The skin sampling and cutting device that is easy to handle manually allows medical staff to better control the position where the device contacts the skin. When taking skin samples, such as diagnosing skin diseases such as melanoma and skin inflammation, which require samples to be obtained from specific lesions, medical staff can use hand feel and visual feedback to accurately place the cutting device in the target area to avoid taking irrelevant tissues, thereby ensuring that the samples obtained can accurately reflect the lesion and improve the accuracy of diagnosis.

[0054] Controlling cutting depth and angle: With the handheld device, medical staff can flexibly adjust the cutting depth and angle according to the sampling purpose and skin condition. For shallow skin lesions, such as seborrheic keratosis, only the epidermis needs to be sampled, and medical staff can adjust the cutting device to a shallow cutting angle and appropriate depth; while for some lesions that may involve the dermis, such as scleroderma, the cutting depth can be increased accordingly. This precise operation can reduce damage to surrounding normal tissues while obtaining enough samples for diagnosis.

[0055] Enhanced operational flexibility

[0056] Adapt to different body parts: The human body's skin morphology and location vary. Some parts, such as fingers, toes, and joints, are complex in shape and frequently move, while some parts, such as the face and neck, have high requirements for appearance. Cutting equipment that is easy to handle manually allows medical staff to easily apply the equipment to various body parts. For example, when sampling at the finger joints, medical staff can flexibly adjust the device holding posture and cutting direction according to the degree of joint bending and skin wrinkles to adapt to the special body surface morphology and successfully complete the sampling operation.

[0057] Dealing with different patient conditions: Different patients have different physical conditions such as obesity, muscle tension, skin laxity, etc. The flexibility of manual handling allows the device to be used effectively on patients of different body shapes and physical conditions. For obese patients, the fat layer under the skin is thicker, and medical staff can hold the device more firmly to ensure that the cutting can reach the appropriate depth; for children or the elderly, whose skin is more delicate, medical staff can complete the sampling through more gentle operations to reduce the patient's discomfort.

[0058] Improve operational efficiency

[0059] Quick response to sampling needs: In clinical work, time is life. When urgent skin sampling is needed to determine the condition, such as suspected serious infectious skin diseases or skin malignancies, the easy-to-handle device allows medical staff to start the operation quickly. Without the need for complicated installation or adjustment processes, medical staff can directly pick up the device for sampling, saving valuable time and enabling patients to receive diagnosis and subsequent treatment faster.

[0060] Simplified operation process: This type of equipment is usually simple in design and easy to operate, which reduces the time for medical staff to learn and adapt to the equipment. Compared with some complex automated equipment, manually operated equipment does not require additional programming, debugging and other steps. For example, in daily dermatology clinics, medical staff can quickly use handheld skin sampling and cutting devices to sample multiple patients, which improves work efficiency and reduces patients' waiting time.

[0061] Improve patient experience

[0062] Reduce patient tension: When medical staff can skillfully and flexibly use easy-to-hold equipment for skin sampling, patients will feel the professionalism and controllability of the operation, thereby reducing tension and fear. For example, medical staff can communicate with patients during the operation, allowing patients to see that the operation of the equipment is simple and under control, which is especially important for some patients who are sensitive to medical operations, such as children and patients with anxiety disorders.

[0063] Reduce patient discomfort: The flexibility of manual operation allows medical staff to adjust the operation method at any time according to the patient's feelings. If the patient feels pain or discomfort during the sampling process, the medical staff can immediately change the force, speed or angle of the cutting to minimize the patient's pain. Moreover, because the device is easy to handle manually, medical staff can control the sampling process more accurately, avoid unnecessary tissue damage, and further reduce patient discomfort.
