Description

Technical Field

[0001] The invention belongs to the technical field of disposable uterine biopsy devices, and in particular relates to a disposable uterine biopsy device with a disinfection function. Background Art

[0002] Disposable uterine biopsy forceps, also known as disposable cervical biopsy forceps, are commonly used medical devices for obtaining biopsy samples of cervical tissue during gynecological examinations. The structure of cervical biopsy forceps generally consists of a power-assisted handle and a double-clawed grabbing head. The two claw-like parts of the grabbing head can be opened and closed, and when closed, they can penetrate the cervical tissue to obtain tissue samples. The handle can control the opening and closing movements of the grabbing head and provide the required force. When using cervical biopsy forceps for biopsy, the doctor will first use instruments such as colposcopes to observe the cervix and determine the location of the biopsy requirement. Then, the doctor inserts the cervical biopsy forceps into the vagina until it reaches the cervix. By operating the handle, the doctor can close the grabbing head, penetrate the cervical tissue, and gently rotate and stretch it to obtain a small section of tissue sample. After the biopsy is completed, the grabbing head will automatically open and release the tissue sample. The main advantage of cervical biopsy forceps is that it is easy to operate and can obtain high-quality biopsy samples in a shorter time. It is suitable for the diagnosis and evaluation of cervical lesions, such as cervical precancerous lesions, cervical polyps, cervicitis, etc. In addition, the stimulation of cervical biopsy forceps is relatively small for patients, and more invasive operations such as surgical excision can be avoided.

[0003] However, it should be noted that when using cervical biopsy forceps for biopsy, relevant hygiene and disinfection requirements should be followed to ensure the safety and hygiene of the operation. The cervical biopsy forceps need to be disinfected before sampling, and disinfection requires the use of disinfection equipment, which increases the cost. The cervical biopsy forceps currently on the market do not have a disinfection function. This phenomenon has become a problem that needs to be solved urgently by people in this field.

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 creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-7 The present invention provides a technical solution: a disposable uterine biopsy device with a disinfection function, comprising a uterine biopsy mechanism and a disinfection mechanism, wherein the uterine biopsy mechanism comprises a handle 1, a handle 2, a clamping block 3, a housing 4, a shaft 5, an extension arm 6, a connecting rod 7, a connecting block 8 and a clamp 9;

[0023] The clamp part 9 includes a lower clamp 91, an upper clamp 92, a movable rod 93 and a pin 94;

[0024] The second grip 2 is fixed to the lower right of the housing 4. A hole is provided on the surface of the housing 4, and the shaft 5 is installed in the hole. The first grip 1 is sleeved on the shaft 5 and is located in the housing 4.

[0025] The clamping block 3 is clamped in the interior of the handle 1 , and the clamping block 3 includes a limit block 31 and an elastic spring 32 . The limit block 31 is located on the right side of the clamping block 3 and is connected to the handle 2 2 via the elastic spring 32 .

[0026] The extension arm 6 is fixedly installed on the left side of the housing 4, and the interior is hollow. The connecting rod 7 is slidably connected in the extension arm 6, and is connected to the handle 1 through the connecting block 8;

[0027] The lower clamp 91 is fixedly mounted on the left end of the extension arm 6, and the upper clamp 92 is fixedly connected to the left end of the connecting rod 7 through a movable rod 93, and the movable rod 93 is slidably connected to the left end of the extension arm 6;

[0028] The upper jaw 92 is disposed in the lower jaw 91 and connected to the lower jaw 91 via a pin 94. The interior of the housing 4 is hollow.

[0029] During the uterine biopsy, the doctor holds the handle 1 with the middle finger, ring finger and little finger, and presses the handle 2 2 with the base of the thumb. Then, the uterine biopsy device is moved to extend the extension arm 6 into the patient's vagina until the clamp 9 reaches the cervix. By pressing the handle 1, the elastic spring 32 is deformed by force, the limit block 31 moves, and presses the handle 1 through the clamp block 3. The handle 1 rotates through the shaft 5, thereby driving the connecting block 8 to tilt slightly to the left, thereby driving the movable rod 93 to move to the left along the extension arm 6 through the connecting rod 7. The movement of the rod 93 causes the upper clamp 92 to rotate through the pin shaft 94, thereby closing with the lower clamp 91. The doctor can close the clamp 9, penetrate the cervical tissue, and gently rotate and stretch it to obtain a small tissue sample. After taking out the sample, the uterine biopsy device is taken out of the vagina and a biopsy is performed. After the biopsy is completed, the doctor releases the grip 1, and the elastic spring 32 deforms and resets the clamp 9 automatically to release the tissue sample. The operation is simple and convenient. The overall structure of the uterine biopsy device is simple, and it can be used as a disposable medical device with low production cost.

[0030] The disinfection mechanism includes a disinfection chamber 10, and the disinfection chamber 10 includes a hydraulic chamber 101, a hydraulic plate 102, a connecting column 103, a guide block 104 and an atomizing nozzle 105;

[0031] The connecting block 8 includes a sliding column 81;

[0032] The disinfection chamber 10 is fixedly mounted above the housing 4, and a slide groove 106 is formed at the connection with the housing 4, and the guide block 104 is slidably connected in the slide groove 106;

[0033] The hydraulic chamber 101 is fixedly installed on the left side of the inner wall of the disinfection chamber 10, the hydraulic plate 102 is slidably connected to the inner wall of the hydraulic chamber 101, the upper end of the guide block 104 is fixed to the right side of the hydraulic plate 102 through the connecting column 103, the guide block 104 is connected to the spring on the left side of the inner wall of the disinfection chamber 10, the atomizing nozzle 105 is installed on the left side of the disinfection chamber 10, and a hose 107 is connected to the left side of the inside of the hydraulic chamber 101.

[0034] The center of the connecting block 8 is provided with a sliding hole 82, and the lower left end is provided with a circular hole 83, the sliding column 81 is slidably connected in the sliding hole 82, and the upper end extends out of the sliding hole 82, and the lower end extends into the circular hole 83;

[0035] A pressing rod 33 is fixed to the right side of the clamping block 3 , and the pressing rod 33 is located in the circular hole 83 .

[0036] The right end of the pressing rod 33 and the lower end of the sliding post 81 are both spherical.

[0037] The left side of the hydraulic plate 102 is filled with 75% medical alcohol.

[0038] The slide post 81 is located on the right side of the guide block 104;

[0039] Before uterine biopsy: the clamp 9 of the uterine biopsy instrument is facing downward, the doctor's middle finger, ring finger and little finger hold the handle 1, and the tiger's mouth presses against the handle 2 2, and the index finger presses the clamping block 3. The clamping block 3 causes the elastic spring 32 to deform under force through the limit block 31, so that the clamping block 3 is displaced to the right, and the clamping block 3 drives the pressing rod 33 to slide to the right along the inner wall of the circular hole 83 until the right end of the pressing rod 33 contacts the lower end of the sliding column 81 and squeezes each other. The sliding column 81 is forced to slide upward along the sliding hole 82, so that its upper end part exceeds the lower end of the guide block 104. Then the doctor repeatedly presses the handle 1 , so that the connecting block 8 continuously moves left and right, and the guide block 104 moves against the sliding column 81. When the guide block 104 moves, the spring is deformed by force, and at the same time, the hydraulic plate 102 is driven to slide to the left along the inner wall of the hydraulic chamber 101 through the connecting column 103. After being squeezed, the 75% medical alcohol in the hydraulic chamber 101 enters the atomizing nozzle 105 through the hose 107 and is sprayed out from the atomizing nozzle 105. The 75% medical alcohol is atomized into small water droplets, which are scattered on the surface of the uterine biopsy device, thereby fully disinfecting the surface of the uterine biopsy device, improving the hygienic safety of sampling, and avoiding infection of patients;

[0040] During uterine live sampling: after disinfection is completed, the index finger releases the clamping block 3, and the clamping block 3 is reset by the force of the elastic spring 32, and the slide column 81 loses the squeeze and slides down and resets by its own weight. At this time, during sampling, pressing the handle 1 will prevent the disinfection mechanism from continuing to work, preventing the 75% medical alcohol from continuing to spray out during live sampling, causing discomfort to the patient's lower body;

[0041] While meeting the requirements of efficient uterine biopsy, the uterine biopsy device can be fully disinfected before sampling. Before sampling, the uterine biopsy device is in contact with the air when it is taken out of the package, and there will be bacteria on the surface. The disinfection with 75% medical alcohol can enhance the improvement of hygiene, and the structure of the entire disinfection mechanism is relatively simple. By making it into an integrated uterine biopsy device, which can not only perform uterine biopsy but also disinfect it, it is different from the split type, has a lower cost, and is simple and convenient to operate.

[0042] The uterine biopsy device is a disposable medical device, and the amount of 75% medical alcohol is set as a disposable consumable.
