Description

Technical Field

[0001] This invention relates to the field of skin tissue sampling technology, specifically to a sample processing component of a skin disease diagnostic device. Background Technology

[0002] Skin tissue trephine drills are primarily used for cutting and processing skin biopsy samples to facilitate subsequent diagnosis or treatment. Trephine drills typically have a cylindrical tip. In actual dermatological diagnosis, trephine drills are usually used to sample skin tissue before microscopic examination and suturing of the sampling site. While current dermatological diagnostic devices can quickly complete cutting and sampling, they are prone to leakage and splashing of pus from cysts when sampling skin tissue containing cysts. Furthermore, they lack automatic negative pressure drainage, which can easily lead to contamination. Additionally, when performing biopsies on elderly patients or areas with loose skin, it is difficult to precisely control the depth of the trephine drill, and the loose skin can hinder the rotary cutting operation, making it difficult to easily stretch the skin outwards to assist in sampling.

[0003] Therefore, we propose a sample processing component for a dermatology diagnostic device. Summary of the Invention

The sample preparation part is equipped with a suction mounting part; The sample preparation part is provided with a stretching aid on the outside; The sample preparation component includes: a handheld tube, on which a trephine is fixedly sleeved; the trephine is used to cut skin tissue; and the trephine has a notch on its side.

[0006] Preferably, the sample preparation component further includes: a cyst puncture needle, which is fixedly installed at the end of the handheld tube; the cyst puncture needle communicates with the interior of the handheld tube.

[0007] Preferably, the cutting telescopic component includes: a cutting telescopic sleeve, which is sleeved on the handheld tube; a telescopic cutter is fixedly installed on the cutting telescopic sleeve; the telescopic cutter is slidably sleeved inside the handheld tube; the telescopic cutter is located at the notch of the trephine; and the outer side of the cutting telescopic sleeve is provided with a rubber coating.

[0008] Preferably, the cutting telescopic component further includes: a cutting spring, the cutting spring being located inside the cutting telescopic sleeve; one end of the cutting spring being fixedly connected to the handheld tube, and the other end of the cutting spring being fixedly connected to the inner side of the cutting telescopic sleeve; the ends of the treble drill and the telescopic cutter are sharpened.

[0009] Preferably, the piston suction component includes: a mounting sleeve threadedly connected to a handheld tube; a pressure relief hole provided on the mounting sleeve; a sliding post slidably sleeved on the mounting sleeve, and a piston fixedly installed at the end of the sliding post; the piston slidably sleeved inside the handheld tube; and the piston is used to move and suction pus.

[0010] Preferably, the piston suction component further includes: a suction spring, which is sleeved on the sliding column; one end of the suction spring is fixedly connected to the bottom of the mounting sleeve, and the other end of the suction spring is fixedly connected to the piston.

[0011] Preferably, the suction mounting component includes: a suction mounting shell, the inner side of which has a sloping structure; a ring of vent holes on the suction mounting shell; a sloping column slidably inserted inside the suction mounting shell, the end of which has a sloping structure; the sloping column abutting the inner sloping surface of the suction mounting shell; a support spring sleeved inside the suction mounting shell, the end of which is connected to the inner side of the suction mounting shell; the other end of the support spring being connected to the sloping column; and the suction mounting shell communicating with the inside of the handheld tube.

[0012] Preferably, the stretching auxiliary component includes: a stretching mounting shell, which is sleeved on the outside of the handheld tube; a lifting ring is slidably sleeved on the outside of the stretching mounting shell; a lifting spring is sleeved on the outside of the stretching mounting shell, with one end of the lifting spring connected to the stretching mounting shell and the other end of the lifting spring connected to the lifting ring; and the bottom of the stretching mounting shell has an arc-shaped structure.

[0013] Preferably, the stretching auxiliary component further includes: a rubber sleeve, which is fitted onto the stretching mounting shell; a lifting ring is fixedly installed at the end of the rubber sleeve; the rubber sleeve is used to stretch the skin outward.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a cutting telescopic component in conjunction with a sample preparation component, facilitating rapid circumferential skin incision for sampling. The structure utilizes an extendable telescopic cutter to ensure complete severance of the bottom of the circumferential area after incision, simplifying operation and eliminating the need to change scalpels. The piston aspiration component prevents pus leakage and splashing during sampling in areas with cysts, particularly important given the high pressure during circumferential incisions and cystic areas. The cyst puncture needle allows for rapid aspiration of pus during incision, while the piston aspiration component facilitates slow, continuous negative pressure aspiration, maintaining pus collection and aiding in subsequent individual pus analysis.

[0016] Using a skin-stretching aid helps to fully stretch the skin outward during circumferential incision, ensuring that the circumferential incision can be rotated downwards normally. This is especially suitable for areas with loose skin, such as elderly patients. If the skin is too loose, the telescopic incision blade will require a lot of downward pressure when rotating, and the control accuracy of the cutting depth will be insufficient. The skin-stretching aid can effectively improve the sampling quality of circumferential biopsy. Attached Figure Description

[0021] The sample component 1 further includes: a cyst puncture needle 103, which is fixedly installed at the end of the handheld tube 101; the cyst puncture needle 103 communicates with the interior of the handheld tube 101; the cutting telescopic component 2 includes: a cutting telescopic sleeve 201 and a telescopic cutter 202, the cutting telescopic sleeve 201 is sleeved on the handheld tube 101; the telescopic cutter 202 is fixedly installed on the cutting telescopic sleeve 201; the telescopic cutter 202 is slidably sleeved inside the handheld tube 101; the telescopic cutter 202 is located at the notch of the trephine 102; the outer side of the cutting telescopic sleeve 201 is provided with a rubber coating; the cutting telescopic component 2 also includes: a cutter tension spring 203, which is located inside the cutting telescopic sleeve 201; the end of the cutter tension spring 203... The cutting spring 203 is fixedly connected to the handheld tube 101, and the other end of the cutting spring 203 is fixedly connected to the inside of the cutting telescopic sleeve 201. The ends of the trephine 102 and the telescopic cutting blade 202 are sharpened. The cutting telescopic component 2 is used in conjunction with the sample preparation component 1 to facilitate rapid circumferential skin incision for sampling. At the same time, this structure utilizes the extendable telescopic cutting blade 202 to facilitate complete severing of the bottom of the circumferential area after circumferential skin incision, making the operation simple and eliminating the need to change the scalpel. Simultaneously, the sample preparation component 1 can be manually operated to quickly perform sampling. The cutting telescopic sleeve 201 is manually pushed outward to extend the telescopic cutting blade 202. The telescopic cutting blade 202 is then inserted under the sampled skin tissue to completely sever the circumferentially incisively ...

[0022] The piston suction component 3 includes: a mounting sleeve 301, a sliding column 302, and a piston 303. The mounting sleeve 301 is threadedly connected to the handheld tube 101. The mounting sleeve 301 has a pressure relief hole. The sliding column 302 is slidably sleeved on the mounting sleeve 301, and the piston 303 is fixedly installed at the end of the sliding column 302. The piston 303 is slidably sleeved inside the handheld tube 101. The piston 303 is used to move and suction pus. The piston suction component 3 also includes: a suction spring 304, which is sleeved on the sliding column 302. One end of the suction spring 304 is fixedly connected to the bottom of the mounting sleeve 301, and the other end of the suction spring 304 is fixedly connected to the bottom of the handheld tube 101. The suction mounting component 4 includes a suction mounting shell 401, a vent 4011, a sloping column 402, and a support spring 403. The inner side of the suction mounting shell 401 has a sloping structure. A ring of vents 4011 is provided on the suction mounting shell 401. The sloping column 402 is slidably inserted into the suction mounting shell 401, and the end of the sloping column 402 has a sloping structure. The sloping column 402 is attached to the sloping inner side of the suction mounting shell 401. The support spring 403 is sleeved inside the suction mounting shell 401, and the end of the support spring 403 is connected to the inner side of the suction mounting shell 401. The other end of the support spring 403 is connected to the sloping column 402. The 401-connected handheld tube 101 incorporates a piston aspiration component 3 to prevent pus leakage and splashing during sampling in skin areas with cysts, especially important during circumcision when pressure is high, particularly in cystic areas. This structure utilizes the cyst puncture needle 103 for rapid aspiration of pus during circumcision, while the piston aspiration component 3 provides slow, continuous negative pressure aspiration, facilitating independent collection and subsequent individual pus testing. The aspiration mounting component 4 allows for easy repositioning of the piston 303, preventing excessively slow pressure release through the pressure relief hole on the mounting sleeve 301. The structure is simple to operate, especially during circumcision. Before operation, first press down the sliding column 302. At this time, the sliding column 302 moves down, causing the piston 303 to also move down and lengthen the suction spring 304. At this time, the support spring 403 can elastically support the inclined column 402 for one-way ventilation. When the piston 303 moves down, the airflow quickly breaks through the inclined column 402 and compresses the support spring 403. At this time, the sliding column 302 can be pressed down quickly by hand. When the sliding column 302 is released, the piston 303 can move up for suction under the pull of the suction spring 304. At this time, the inclined column 402 of the inclined structure can seal and fit the suction mounting shell 401. At this time, the pressure can only be released slowly through the pressure relief hole on the mounting sleeve 301.

[0023] In Example 2, based on Example 1, the stretching auxiliary component 5 includes: a stretching mounting shell 501, a lifting ring 502, and a lifting spring 503. The stretching mounting shell 501 is sleeved on the outside of the handheld tube 101; the lifting ring 502 is slidably sleeved on the outside of the stretching mounting shell 501; the lifting spring 503 is sleeved on the outside of the stretching mounting shell 501, with one end of the lifting spring 503 connected to the stretching mounting shell 501 and the other end connected to the lifting ring 502; the bottom of the stretching mounting shell 501 has an arc-shaped structure; the stretching auxiliary component 5 also includes: a rubber sleeve 504, which is sleeved on the stretching mounting shell 501; the lifting ring 502 is fixedly installed on the end of the rubber sleeve 504; the rubber sleeve 504 is used to stretch the skin outwards; the stretching auxiliary component 5 further includes: a rubber sleeve 504, which is sleeved on the stretching mounting shell 501; the lifting ring 502 is fixedly installed on the end of the rubber sleeve 504; the rubber sleeve 504 is used to stretch the skin outwards; the stretching auxiliary component... Component 5 also includes: a lifting ring 505 and a reset spring 506. The lifting ring 505 is sleeved inside the stretching mounting shell 501. The lifting ring 505 is fixedly installed at the other end of the rubber sleeve 504. The rubber sleeve 504 has an adhesive coating on its outer side. The reset spring 506 is sleeved inside the stretching mounting shell 501 and is connected between the lifting ring 505 and the stretching mounting shell 501. The use of the stretching auxiliary component 5 can help to stretch the skin outward and tighten it completely when operating the circumferential skin tissue, ensuring normal downward circumferential cutting. It is more suitable for elderly patients and other areas with loose skin. If the skin is too loose, it will cause a lot of downward pressure when the telescopic cutter 202 is rotated, and the cutting depth control accuracy will be poor. It effectively improves the quality of circumferential biopsy sampling.

[0024] The working principle of this embodiment is as follows: First, before circumcision, the rubber sleeve 504 is applied to the skin surface. At this time, the lifting ring 502 is manually pulled up while the skin stretching housing 501 is pressed down, causing the rubber sleeve 504 to adhere to the skin surface. Pulling up the lifting ring 502 will pull the rubber sleeve 504 out of the skin stretching housing 501. When the rubber sleeve 504 is pulled out, it can rub against the skin, helping to stretch the skin outward and make it easier for the skin to be flat and stable during subsequent circumcision. First, the sliding column 302 is pressed down. At this time, the sliding column 302 moves down, causing the piston 303 to also press down and lengthen the suction spring 304. At this time, the support spring 403 can elastically support the inclined column 402 to perform one-way ventilation. When the piston 303 moves down, the airflow quickly breaks through the inclined column 402 and compresses the support spring 403. At this time, the sliding column 302 can be quickly pressed down manually. When the sliding column 302 is released, the airflow will be compressed. When the moving column 302 is in motion, the piston 303 can move upward to perform suction under the pull of the suction spring 304. At this time, the inclined column 402 of the inclined structure can close and fit the suction mounting shell 401. At this time, pressure can only be slowly released through the pressure relief hole on the mounting sleeve 301. The piston 303 slowly rises to perform suction. Holding the sample preparation part 1, the trephine 102 and the telescopic cutter 202 are placed against the skin and pressed down. At this time, the cyst puncture needle 103 will also pierce the skin. Once pus is present, it can be suctioned by moving the piston 303 upward. At the same time, the sample preparation part 1 is manually rotated to drive the trephine 102 and the telescopic cutter 202 to rotate and cut the skin tissue. Then, the cutting telescopic sleeve 201 can be manually pushed outward to drive the telescopic cutter 202 to extend. The telescopic cutter 202 is inserted under the sampled skin tissue to completely cut the circumferentially cut skin tissue.
