[0031] Press-needling is a micro-needle technique that inserts needles into superficial acupuncture points, instantly improving clinical symptoms and achieving a long-lasting "acupuncture treatment" effect. Resembling a thumbtack, the press-needle consists of an upper ring and a lower body, approximately 2mm long and 0.25mm in diameter. The body is pressed and placed subcutaneously at the corresponding acupuncture point. Needling typically lasts 1-2 days, but can range up to 6-7 days, depending on the condition. Compared to traditional acupuncture, press-needling has gained popularity due to its many advantages, including ease of use, immediate results, anytime, anywhere performance, and minimal pain.

[0032] In the related art, the sliding rod is moved by pulling the handle, which drives the fixed clamp to rotate when the sliding rod moves, so that the bottom part approaches and can clamp the required object, thereby completing the purpose of clamping. However, when using the existing device, one hand is required to hold the grip body and the other hand is required to pull the handle to rotate the fixed clamp, which requires two hands to complete the operation, which is inconvenient.

[0033] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a medical clamp. When the press needle needs to be extracted, you can hold the handle 12 and then place the bottom end of the clamping rod 21 on the press needle. You only need to grab the grip plate 27 so that the grip plate 27 slides inside the slide groove 26 and moves toward the direction of the handle 12, while driving the cylinder 24 to move upward to compress the spring 25. During the upward movement, the connecting rod 23 at the bottom will be driven to rotate, so that the bottom end of the connecting rod 23 pulls the clamping rod 21 to rotate with the connection point of the cross bar 22 as the center of the circle, so that the bottom end of the clamping rod 21 can clamp the press needle and pull the press needle off the patient's skin.

[0034] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0035] Combine Figures 1-4 The embodiment of the present application provides a medical clamp, comprising: a cylinder 11 with a handle 12 on its top; a clamping assembly 2 is provided inside the cylinder 11, and the clamping assembly 2 comprises: a clamping rod 21 provided inside the cylinder 11; one end of a cross bar 22 passes through the clamping rod 21 and is connected to the inner side wall of the cylinder 11 at both ends; a connecting rod 23 is provided at the top end of the clamping rod 21 and is rotatably connected to the clamping rod 21; a cylinder 24 is slidably provided inside the cylinder 11, and its bottom end is rotatably connected to the top end of the connecting rod 23; a spring 25 is provided at the top of the cylinder 24, and its top end is connected to the handle 12; a slide groove 26 is opened on the outer side wall of the cylinder 11; one end of a grip plate 27 is inserted into the interior of the slide groove 26 and is connected to the spring 25.

[0036] Specifically, the clamping rod 21 is designed as a cross rod and rotates at the connection point in the middle.

[0037] When the plucker needs to be pulled out, the user can hold the handle 12 and place the bottom end of the clamping rod 21 on the plucker, then grasp the grip plate 27 and slide it in the sliding groove 26, and move it towards the handle 12, which drives the cylindrical rod 24 to move upwards and compress the spring 25, and in the process of moving upwards, the bottom connecting rod 23 is rotated, and the bottom end of the connecting rod 23 pulls the clamping rod 21 to rotate around the connection of the cross rod 22, so that the bottom end of the clamping rod 21 clamps the plucker, and the plucker is pulled off the patient's skin.

[0038] In some embodiments, the surface of the handle 12 is designed in an arc shape.

[0039] The arc-shaped design can improve comfort when grasping.

[0040] In some embodiments, the outer side wall of the cylindrical rod 24 is attached to the inner side wall of the cylinder 11.

[0041] The attachment of the outer side wall of the cylindrical rod 24 to the inner side wall of the cylinder 11 can limit the movement trajectory of the cylindrical rod 24 and prevent the cylindrical rod 24 from shaking.

[0042] In some embodiments, the clamping assembly 2 further comprises a vertical rod 28 arranged inside the spring 25, with the top end connected to the handle 12 and the bottom end inserted into the inside of the cylindrical rod 24.

[0043] The design of the vertical rod 28 can protect the spring 25 from bending when the cylindrical rod 24 moves upwards to compress the spring 25, thereby prolonging the service life of the spring 25.

[0044] In some embodiments, the clamping assembly 2 further comprises a baffle plate 281 arranged inside the cylindrical rod 24 and connected to the bottom end of the vertical rod 28.

[0045] The design of the baffle plate 281 can prevent it from disengaging from the cylindrical rod 24 when the vertical rod 28 moves up and down.

[0046] In some embodiments, the clamping assembly 2 further comprises a plurality of tooth blocks 29 arranged on one side of the bottom end of the clamping rod 21.

[0047] The design of the tooth blocks 29 can increase the friction when the clamping rod 21 clamps the object, thereby making the clamping more secure.

[0048] In some embodiments, the outer side wall of the cylinder 11 is provided with a protection assembly 3, which comprises a shell 31 arranged on the outer side wall of the cylinder 11, and a frame 32 arranged on the top outer side wall of the shell 31.

[0049] During use, when the cylinder 11 needs to be stored and protected, it is only necessary to put the shell 31 on the outer wall of the cylinder 11 and push it upward, while pushing the grip plate 27 upward to compress the spring 25, and finally rotate the frame 32 to the top of the handle 12. After releasing it, the spring 25 rebounds and pushes the cylinder 24 to drive the grip plate 27 to move downward to resist the downward movement of the shell 31. Because of the restriction of the frame 32, the shell 31 will not be separated from the cylinder 11, thereby better protecting the cylinder 11 and the clamping rod 21.

[0050] In some embodiments, the protective component 3 further includes: a groove 33 opened on the top of the handle 12 .

[0051] The design of the groove 33 can make the connection between the frame 32 and the handle 12 closer and less likely to separate during use.
