Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to instruments related to cell sampling or biopsy. Background Art

[0002] Sampling forceps is a medical device used to collect certain tissue, cell or tumor samples in the human body for observation and pathological examination. There are many types of sampling forceps, which are widely used in the medical field, such as gastrointestinal endoscopes, pulmonary endoscopes, hysteroscopes, nasal endoscopes, etc. Sampling forceps with different structures have their own functional uses. The sampling forceps includes a clamp and a pushing component that drives the clamp to work. During the operation, the movement of the pushing component generates pulling and pushing forces on the clamp, thereby causing the connecting component on the clamp to move. When the connecting component moves, it can pull the two scissor-shaped clamping parts to move, and finally realize the clamping and loosening steps.

[0003] The application number is CN202222615174.1; the patent name is a pushing structure for sampling forceps; it discloses a sampling forceps with a detachable pushing component; however, during use, this sampling forceps still uses the pushing force of the hand to push the pushing component to work; this makes the sampling forceps prone to excessive force and the contact area with the patient's sampling site is too large, causing greater trauma to the patient during sampling.

[0004] Therefore, in order to solve the technical problem of causing greater trauma to patients during the sampling process, a new sampling forceps is urgently needed.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0046] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0047] Since the operator needs to push the pushing component to move when using the sampling forceps, and since the warning force between the pushing component and the sampling rack of each sampling forceps is different, or the warning force between the pushing component and the sampling rack changes due to contact with liquid during use, the operator often uses excessive force during use, causing the sampling forceps to be too close to the patient's sampling area, thereby increasing the area of ​​trauma caused by sampling.

[0048] The pushing component is driven to slide on the sampling frame in a rotating manner to control the opening size of the clamp, thereby conveniently controlling the opening size of the clamp.

[0049] The defects in the above solutions are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in the present disclosure below should be the contributions made by the inventors to the present disclosure during the disclosure process.

A strong magnet is provided inside the rotating member 5. The pushing member 4 is made of ferromagnetic material or has a strong magnet inside, so that the rotating member 5 remains in contact with the pushing member 4 through the protective member 6.

[0059] The following describes the technical solution in detail by taking the example that the rotating member 5 contains a strong magnet and the pushing member 4 is made of ferromagnetic material.

[0060] refer to Figure 2 In some embodiments, the pushing member 4 includes a first member and a second member, which are used to facilitate the disassembly of the pushing member 4. The first member and the second member are both in contact with the threaded rod 22. The pushing member 4 is made of ferromagnetic material and is used to maintain magnetic attraction with the rotating member 5, so that the pushing member 4 remains in contact with the rotating member 5 through the protective member 6.

[0061] refer to Figure 2 and Figure 7 In some embodiments, the material of the first member and the second member is specifically iron, which is used to ensure that the pushing member 4 maintains contact with the rotating member 5 through the protective member 6. The connecting portion 41 between the first member and the second member passes through the first groove 23, which is used to guide the pushing member 4 so that its movement path is accurate.

[0062] refer to Figure 7 In some embodiments, the connecting portion 41 in the middle of the pushing member 4 is located in the first groove 23 of the sampling rack 2 , so that the first groove 23 can limit the extreme position of the pushing member 4 in the length direction of the sampling rack 2 .

[0063] refer to Figure 1 In some embodiments, a second groove 24 is provided on the sampling rack 2, and the scale 7 is located in the second groove 24, which is used to avoid interference between the scale 7 and the rotating member 5 and the pushing member 4. The number of the second groove 24 is not less than one, which is used to facilitate the operator to observe the relative position between the scale 7 and the pushing member 4; the length direction of the second groove 24 is parallel to the axis of the sampling rack 2.

[0064] refer to Figure 1In some embodiments, a scale 7 is provided in the second slot 24 of the sampling rack 2; the second slot 24 is located at the threaded rod 22 so that the movement direction of the pusher 4 is consistent with the distribution track direction of the scale 7, which is used as a reference for the position change of the pusher 4.

[0065] refer to Figure 4 In some embodiments, the sampling rack 2 further includes a mounting groove 25 and a mounting tube 26 in the mounting groove 25 . The pushing member 4 is connected to the jaws 1 through a pushing rod 8 . The pushing rod 8 drives the opening size of the jaws 1 . The pushing rod 8 passes through the mounting tube 26 and the mounting groove 25 .

[0066] refer to Figure 1 and Figure 5 and Figure 6 In some embodiments, the clamp portion 1 is fixed to the end of the mounting tube 26; a handle 21 is provided at one end of the sampling frame 2 away from the clamp portion 1 for operating the sampling clamp.

[0067] The working principle of the utility model is as follows: before starting to use the rotary-driven sampling forceps, the rotary-driven sampling forceps will be taken out. When using the rotary-driven sampling forceps: the operator drives the sampling forceps to move toward the patient's sampling location. After driving the sampling forceps to a certain position, the operator stops driving the sampling forceps to continue moving. The operator first manually rotates the rotating member 5 to rotate the rotating member 5 outside the sampling rack 2. During this process, the rotating member 5 moves on the sampling rack 2 in the direction close to the clamp portion 1. During this process, the rotating member 5 pushes the pushing member 4 to move toward the clamp portion 1. During this process, the pushing member 4 drives the clamp portion 1 to work through the pushing rod 8. During this process, the clamping portion of the clamp portion 1 opens. When the clamping portion of the clamp portion 1 opens to a certain angle, the opening step of the sampling forceps is completed. In the next step, the operator drives the sampling forceps to move further to the sampling position, and then the operator rotates the rotating member 5 in the opposite direction to move the rotating member 5 on the sampling rack 2 in the direction away from the clamp 1; since the pushing member 4 is made of iron, the rotating member 5 contains a strong magnet, which causes the rotating member 5 to attract the pushing member 4 and move it in the direction away from the clamp 1. During this process, the pushing member 4 controls the clamp 1 to close through the pushing rod 8. During this process, the clamping part of the clamp 1 clamps the part of the patient to be sampled and removes the part of the patient to be sampled from the human tissue. The opening of the clamp 1 stops after closing, and a certain amount of sample is clamped from the patient, thereby completing the sampling step, and the operator stops operating the rotating member 5; when it is necessary to continue sampling the patient, the above steps are repeated until the work is completed.

[0068] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
