Description

Technical Field

[0001] The invention relates to a sampler, in particular to a sampler for skin diseases. 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. Combining the visible and tangible skin lesions such as erythema, papules, nodules, blisters, wheals, scales, erosions or lichens that appear on the skin, mucous membranes, nails, hair, etc., and 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 differentially diagnose clinically, and whose diseases are stubborn, recurrent, or ineffective with conventional treatments, skin sampling is usually performed to assess whether the skin has abnormal cell proliferation or other pathological changes, thereby helping doctors determine the diagnosis of skin diseases and formulate treatment plans. The principle is to observe the morphology, structure, and arrangement of cells through pathological examination of skin tissue to determine the nature and extent of skin lesions.

[0003] When sampling the skin, the trephine is used as a skin tissue sampling tool, and its structure is relatively simple and professional. However, after the trephine is sampled, the bottom of the tissue is not disconnected from the human body. The doctor will use tweezers or an injection needle to gently clamp or pick up the tissue sample, and then use iris scissors to cut it from the base to complete the sampling process, making the skin sampling process inconvenient. At the same time, one end of the tissue is easy to adhere to the inside of the trephine, making it difficult for the sampled tissue to separate from the drill bit.

[0004] In view of the above problems, we provide a sampler for skin diseases. Summary of the invention

[0034] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0035] An embodiment of the present application provides a sampler for skin diseases.

[0036] Embodiment 1, as Figure 1-6 shown.

[0037] A sampler for skin diseases, comprising a barrel 1;

[0038] The barrel 1 is a hollow cylindrical structure with an open top surface. The top of the barrel 1 is symmetrically provided with handrails 11 to facilitate medical personnel to hold the sampler. The bottom of the barrel 1 is provided with a sampling port 12, and the sampling assembly 3 extends from the sampling port 12 to the bottom of the barrel 1 to complete skin tissue sampling.

[0039] A sampler for skin diseases includes a protective component 2, which is mounted at the bottom end of the barrel 1 and is slidably connected to the barrel 1. The protective component 2 can house a cutter head 37 so that the cutter head 37 is located inside the protective component 2 to prevent the cutter head 37 from causing harm to medical staff or patients during use; on the other hand, it can prevent the cutter head 37 from touching a contaminated environment, and an additional disinfection step is added.

[0040] The protection assembly 2 includes a top ring 21, a slide bar 22, a contact ring 23, and a support spring 24. The top ring 21 is slidably connected to the outside of the cylinder 1. The top ring 21 slides up and down along the outside of the cylinder 1. A plurality of slide bars 22 are arranged at the bottom of the top ring 21. The contact ring 23 is arranged at the bottom of the slide bar 22. A plurality of support springs 24 are arranged between the contact ring 23 and the bottom of the cylinder 1. When sampling, the medical staff holds the sampler, aligns the contact ring 23 with the skin sampling site and presses it to compress the support spring 24, so that the blade head 37 contacts the target skin tissue. The design of the sampling ring can also ensure that the sampling and cutting process remains perpendicular to the patient's skin without deviation, and the target skin tissue is cut to the fat layer.

[0041] A sampler for skin diseases, comprising a sampling assembly 3, installed inside the barrel 1;

[0042] The sampling assembly 3 includes a support frame 31, a sliding frame 32, a sampling push rod 33, a sampling motor 34, a mounting frame 35, a sampling barrel 36, and a cutter head 37. The support frame 31 is arranged on the top of the cylinder body 1, the sampling push rod 33 is installed at the bottom of the support frame 31, the sliding frame 32 is installed at the output end of the sampling push rod 33, the sliding frame 32 is slidably connected to the inner cavity of the cylinder body 1, the sampling motor 34 is installed at the bottom of the sliding frame 32, the output shaft of the sampling motor 34 is arranged on the mounting frame 35, the sampling barrel 36 is installed at the bottom of the mounting frame 35, and the cutter head 37 is installed at the bottom of the sampling barrel 36. When sampling, the barrel 1 is pressed, the blade head 37 contacts the target skin tissue, and then the sampling motor 34 and the sampling push rod 33 are started. Driven by the sampling push rod 33, the sampling barrel 36 moves down to a specified depth, and the blade head 37 cuts the target skin tissue to the fat layer. The cut tissue sample is located inside the sampling barrel 36. This avoids the problem of insufficient or excessive skin sampling depth.

[0043] The mounting frame 35 includes a mounting plate 351 and a transmission bar 352. The mounting plate 351 is disposed on the output shaft of the sampling motor 34. The transmission bar 352 is arc-shaped. A fixed track 361 matching the transmission bar 352 is disposed on the outside of the sampling barrel 36. A plurality of transmission bars 352 are disposed at equal intervals at the bottom edge of the mounting plate 351. The transmission bar 352 is inserted into the fixed track 361 on the outside of the sampling barrel 36. The arc center of the transmission bar 352 is located on the outside of the sampling barrel 36. The arc-shaped transmission bar 352 facilitates the installation and removal of the sampling barrel 36. When installing and removing, the fixed track 361 only needs to be aligned with the transmission bar 352, and then the sampling barrel 36 is inserted until the top end thereof contacts the mounting plate 351. The arc-shaped transmission bar 352 can imprison the sampling barrel 36 inside. In addition, the transmission bar 352 can also transmit the torque of the motor to drive the sampling tube 36 to rotate, and the skin is cut through the blade head 37 at the bottom thereof.

[0044] The detachable design of the sampling tube 36 makes the sampling tube 36 more portable and more convenient to disinfect and sterilize the sampling tube 36 after use.

[0045] The bottom end of the protection component 2 is provided with a mounting groove 231, and a distance sensor 232 is installed in the mounting groove 231. The distance sensor 232 can detect whether the cutter head 37 has dropped to the inner side of the contact ring 23, that is, the cutter head 37 is in contact with the target skin surface at this time. The sampling depth of the sampling barrel 36 is calculated.

[0046] A fixed magnet 211 is installed on the outside of the top ring 21. When the distance sensor 232 detects that the blade head 37 is in contact with the target skin, the fixed magnet 211 is energized to fix the top ring 21 on the surface of the barrel 1, thereby fixing the distance between the contact ring 23 and the barrel 1, which is convenient for controlling the skin sampling depth.

[0047] A sampler for skin diseases comprises a guide assembly 4 installed inside the sample assembly.

[0048] The derivation assembly 4 includes a derivation push rod 41 and a push plate 42. The derivation push rod 41 is installed at the bottom center of the mounting frame 35, and the push plate 42 is arranged at the output end of the derivation push rod 41. After sampling is completed, the tissue sample is ejected from the sampling tube 36 through the derivation assembly 4. That is, the derivation push rod 41 extends to drive the push plate 42 to eject the tissue sample from the bottom of the sampling tube 36.

[0049] The bottom surface of the push plate 42 is provided with a grab hook assembly 5, through which the top of the tissue sample is fixed to prevent the tissue sample from being separated from the sampling tube 36 when the sampler is pulled out.

[0050] The grab hook assembly 5 includes a grab hook 51, an inner spike 52, and an electromagnet 53. A pair of the grab hooks 51 are symmetrically connected to the bottom edge of the push plate 42. A plurality of inner spikes 52 are provided on the inner side of the bottom of the grab hook 51. The electromagnets 53 are installed on the outer side of the grab hook 51 and the inner wall of the sampling tube 36. The electromagnets 53 attract or repel each other. The rotation of each grab hook 51 is controlled by the electromagnet 53. When the two electromagnets 53 attract, the grab hook 51 opens; when the two electromagnets 53 repel, the grab hook 51 rotates inward to fix the tissue sample.

[0051] When the sampling tube 36 is inserted into the skin tissue to a specified depth, the electromagnet 53 is energized to repel each other, causing the two grabbers 51 to rotate inward, fix the top of the tissue sample, and penetrate into the interior of the tissue sample through the inner thorn 52. At this time, when the sampling tube 36 is raised, the tissue sample will not be separated from the sampling tube 36, which is convenient for subsequent cutting of the tissue sample.

[0052] A sampler for skin diseases comprises a shearing component 6 installed at the bottom end of the protection component 2. After the target skin is cut, the bottom end of the tissue sample is sheared off by the shearing component 6 to separate the tissue sample from the human body.

[0053] The shearing assembly 6 includes an inner cutter 61, an outer cutter 62, and a shearing push rod 63. The bottom of the contact ring 23 is symmetrically provided with shearing grooves on both sides. The shearing push rods 63 are installed in the shearing grooves. The inner cutter 61 and the outer cutter 62 are installed at the output ends of the two shearing push rods 63. After the target skin is cut, the sampling tube 36 is raised, and the two shearing push rods 63 extend to drive the inner cutter 61 and the outer cutter 62 to move toward each other until they are cut into each other, thereby cutting the tissue sample.

[0054] The outer cutter 62 is matched with the inner cutter 61, and the two are close to each other to cut the tissue sample. The outer cutter 62 is an outer arc structure, and the inner cutter 61 is an inner arc structure, and the arcs of the two are the same. The outer cutter 62 is a single-edged blade, and the blade is located in the middle of the outer cutter 62; the inner cutter 61 is a double-edged blade, and the blade is located on the upper and lower sides. The blade of the inner cutter 61 is matched with the blade of the outer cutter 62. The double-edged design of the two cutters can ensure that the tissue sample is cut thoroughly without adhesion, avoiding secondary damage to the patient.

[0055] A disinfection assembly 7 is disposed inside the contact ring 23 to disinfect the target skin and the sampling site after the sampling is completed.

[0056] The disinfection assembly 7 includes a disinfection ring 71, a nozzle 72, a storage box 73, and a micro pump 74. The disinfection ring 71 is installed inside the contact ring 23. The disinfection ring 71 is a hollow structure. A plurality of nozzles 72 are installed at equal intervals inside the disinfection ring 71. The storage box 73 is installed in the inner cavity of the barrel 1. Disinfectants such as alcohol are stored inside the storage box 73. The micro pump 74 is installed at the bottom of the storage box 73. The input end of the micro pump 74 is connected to the storage box 73, and the output end of the micro pump 74 is connected to the disinfection ring 71 through a pipeline. The alcohol in the storage box 73 is pumped into the disinfection ring 71 through the micro pump 74, and then sprayed out through the nozzle 72 to sterilize the target skin.

[0057] A stabilizing component 8 is installed at the bottom of the contact ring 23 to ensure the stability of the sampler during skin sampling and prevent it from sliding against the skin, which would cause the sampler to tilt and cause secondary damage to the patient.

[0058] The stabilizing assembly 8 includes a negative pressure ring 81, a stabilizing ring 82, and a negative pressure pump 83. The stabilizing ring 82 is installed at the bottom of the contact ring 23. The stabilizing ring 82 is made of rubber and is an annular structure with an open bottom. The shape of the stabilizing ring 82 matches the contact ring 23. The inner and outer side walls of the stabilizing ring 82 are inclined outwards respectively. The negative pressure ring 81 is arranged on the top of the contact ring 23. The negative pressure ring 81 is connected to the stabilizing ring 82 through a plurality of pipes, and the pipes are evenly spaced. The negative pressure pump 83 is installed on the inner side of the cylinder 1, and the negative pressure pump 83 is connected to the negative pressure ring 81 through a pipe. When fixing, the stabilizing ring 82 is pressed to the target skin, and then the negative pressure pump 83 is started to put the negative pressure ring 81 and the stabilizing ring 82 in a negative pressure state. The design of the negative pressure ring 81 can make the air in the stabilizing ring 82 be drawn out as evenly as possible to avoid the sampler from tilting.

[0059] When the present invention is used:

[0060] Aim the sampler at the target skin, press the barrel, and start the negative pressure pump at the same time, so that the stabilizing ring is adsorbed around the target skin. Then, start the disinfection component and the micro pump to pump the alcohol in the storage box into the disinfection ring, and then spray it out through the nozzle to sterilize and disinfect the target skin. After the disinfection is completed, press the barrel to make the cutter head contact with the skin, and the sensor detects that the cutter head drops to the inside of the contact ring, that is, at this time, the cutter head is in contact with the surface of the target skin. The fixed magnet is energized to fix the top ring on the surface of the barrel, thereby fixing the distance between the contact ring and the barrel. At this time, start the sampling motor and the sampling push rod. Driven by the sampling push rod, the sampling barrel moves down to a specified depth, and the target skin tissue is cut to the fat layer by the cutter head. The cut tissue sample is located inside the sampling barrel. When the sampling barrel extends into the skin tissue to a specified depth, the electromagnet is energized to repel each other, so that the two grabbers rotate inward, fix the top of the tissue sample, and penetrate into the tissue sample through the internal puncture. The sampling tube is raised, the shearing assembly is started, and the two shearing push rods are extended to drive the inner cutting knife and the outer cutting knife to move toward each other until they are engaged with each other, thereby shearing the tissue sample.

[0061] After sampling is completed, the tissue sample is ejected from the sampling tube through the extraction assembly. That is, the extraction push rod extends to drive the push plate to eject the tissue sample from the bottom of the sampling tube. After ejection, the medical staff uses tweezers to push open the grab hook and take out the tissue sample.

[0062] At this point, skin sampling is complete.
