Description

Technical Field

[0001] This utility model belongs to the field of medical clamps, specifically a press-type replaceable clamp. Background Technology

[0002] With the continuous advancement of technology, people have increasingly higher requirements for tools; driven by the development of materials science, mechanical design and other fields, various new fixture design concepts have emerged.

[0003] During surgery, doctors need to use clamps to fix tissues and stop bleeding. The heads of traditional clamps are prone to sticking to tissue fragments, which may interfere with the operation and increase surgical risks. For example, in some delicate minimally invasive surgeries, sticky tissue fragments may affect the doctor's field of vision and operational precision; the medical environment has extremely high hygiene requirements, and traditional clamps are difficult to clean thoroughly, easily breeding bacteria, which may lead to cross-infection and pose a serious threat to the patient's health.

[0004] Traditional forceps and other clamps require the use of both hands to open the opening wide. They are usually clamped according to the fixed clamping distance of the forceps, which is not convenient to operate. Maintaining the clamping state requires continuous force from the hands, which may waste time in emergency situations or when quick operations are needed, and it is also easy to stick tissue blocks.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a press-type replaceable clamp. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a press-type replaceable clamp to solve the problem that existing clamps such as tweezers require both hands to open the opening, and are usually clamped according to the fixed clamping distance of the tweezers, which is not convenient to operate and requires continuous force from the hands to maintain the clamping state.

[0007] A press-type replaceable clamp includes a clamp housing and a clamping component. The clamp housing has a cylindrical structure, and a magnetic base is fixed to the bottom wall of the clamp housing. The clamping component is installed in the magnetic base, and a press assembly is also installed inside the clamp housing.

[0008] The pressing assembly includes a limiting ring fixed to the inner top wall of the clamp housing, a pressing column sliding within the limiting ring, a pressing button fixed to one end of the pressing column, a connecting plate fixed to the other end of the pressing column, a return spring installed between the limiting ring and the pressing button, a pressure rod fixed to one end of the connecting plate, a fixing member fixed to the inner wall of the clamp housing, a magnetic suction frame installed on the upper surface of the magnetic suction base, a rotating roller rotating on the inner wall of the fixing member, and a traction rope connecting the pressure rod, the rotating roller, and the magnetic suction frame; and a clamping member pressing at the bottom of the magnetic suction frame; the magnetic suction frame and the magnetic suction base attract each other.

[0009] Preferably, the clamping member includes two sets of symmetrically arranged clamping heads and squeezing parts, wherein the clamping heads and squeezing parts have a "V" shaped structure.

[0010] Preferably, the bottom surface of the magnetic holder is symmetrically fixedly connected with an extrusion head, and the position of the extrusion head corresponds to the extrusion part.

[0011] Preferably, a connecting frame is fixedly connected to both sides of the pressure rod, and the connecting frame is connected to the traction rope.

[0012] Preferably, the upper part of the clamping member is fixedly connected to a connector, and the bottom surface of the magnetic base is provided with a connecting groove, and the connector is threadedly engaged with the connecting groove.

[0013] Preferably, the clamping component is made of antibacterial and bacteriostatic materials, including silver ion antibacterial materials and nano antibacterial materials.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, by setting up a clamping component and a pressing component, allows the clamp to be opened by pressing the button with only one hand, eliminating the need for two-handed operation and greatly improving the convenience of operation; by controlling the pressing distance of the button, the opening and closing degree of the clamp head can be flexibly adjusted to meet the clamping needs of items of different sizes. Unlike traditional tweezers, it does not require clamping according to a fixed clamping distance, nor does it require continuous hand force to maintain the clamping state, saving manpower and improving work efficiency.

[0016] 2. This utility model allows for quick replacement of the clamping parts by setting a connector and a connecting groove. Furthermore, the use of antibacterial and bacteriostatic materials can effectively reduce bacterial growth and improve hygiene and safety when used in the medical field. The silver ion antibacterial material reduces the adhesion between the item and the clamping parts, making it less likely to stick even when in contact, further reducing the occurrence of adhesion problems.

Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides a press-type replaceable clamp, including a clamp housing 1 and a clamping member 8. The clamp housing 1 has a cylindrical structure, and a magnetic base 7 is fixed on the inner bottom wall of the clamp housing 1. The clamping member 8 is installed in the magnetic base 7, and a press assembly is also installed inside the clamp housing 1.

[0026] The pressing assembly includes a limiting ring 2 fixed to the inner top wall of the clamp housing 1, a pressing column 4 sliding within the limiting ring 2, a pressing button 3 fixed to one end of the pressing column 4, a connecting plate 5 fixed to the other end of the pressing column 4, a return spring 6 installed between the limiting ring 2 and the pressing button 3, a pressure rod 11 fixed to one end of the connecting plate 5, a fixing member 12 fixed to the inner wall of the clamp housing 1, a magnetic suction frame 16 installed on the upper surface of the magnetic suction base 7, a rotating roller 14 rotating on the inner wall of the fixing member 12, and a traction rope 15 connecting the pressure rod 11, the rotating roller 14, and the magnetic suction frame 16; and the bottom of the magnetic suction frame 16 presses against the clamping member 8; the magnetic suction frame 16 and the magnetic suction base 7 attract each other;

[0027] The clamping member 8 includes two sets of symmetrically arranged clamping heads 801 and pressing parts 802, which are in a "V" shape.

[0028] The bottom surface of the magnetic holder 16 is symmetrically fixed with an extrusion head 17, and the position of the extrusion head 17 corresponds to the extrusion part 802.

[0029] Both sides of the pressure rod 11 are fixedly connected to the connecting frame 13, which is connected to the traction rope 15.

[0030] Before rising, the magnetic chuck 16 is attracted by the magnetic base 7 and stably positioned at the magnetic base 7. The pressing head 17 below the magnetic chuck 16 presses against the pressing part 802 of the clamping member 8, thereby pressing the clamp head 801 tightly and achieving stable closure of the clamp head 801. The opening and closing degree of the clamping member 8 can be quickly controlled by the pressing assembly. By pressing the pressing button 3, the pressing button 3 drives the pressing column 4 and the pressing rod 11 to move downwards. The pressing rod 11 simultaneously drives the two sets of connecting frames 13 to move downwards. When the connecting frames 13 move downwards, they pull the traction rope 15 to shift, and the traction rope 15 pulls the magnetic chuck 16 upwards. After the magnetic chuck 16 moves upwards, the pressing part 802... 02. Once the squeezing head 17 is released from its restraint, it automatically resets, and the clamping part 8 automatically opens and closes. By controlling the pressing distance of the pressing button 3, the limiting distance of the squeezing head 17 can be adjusted, thereby flexibly controlling the opening and closing degree of the clamping head 801. When the pressing button 3 is fully pressed down, the clamping head 801 opens and closes to its maximum distance. The contact area between the clamping head 801 and the item is smaller than that of traditional clamps, thus reducing the possibility of adhesion. By flexibly adjusting the opening and closing degree of the clamping head 801 by controlling the pressing distance of the pressing button 3, it can be adjusted according to the size of different items, avoiding large-area contact and adhesion caused by over-clamping.

[0031] The upper part of the clamping member 8 is fixedly connected to the connector 9, and the bottom surface of the magnetic base 7 is provided with a connecting groove 10, and the connector 9 is threadedly engaged with the connecting groove 10.

[0032] Clamping component 8 is made of antibacterial and bacteriostatic materials, including silver ion antibacterial materials and nano antibacterial materials. This clamp is mainly used in the biological industry for tissue processing and transfer, and needs to have good antibacterial properties to avoid contamination during tissue transfer.

[0033] As can be seen from the above, when the finger presses the pressing button 3 on the top of the clamp housing 1, the pressing button 3 drives the pressing column 4 connected to it to move downward, and the pressure rod 11 connected to the other end of the pressing column 4 also moves downward; the connecting frame 13 fixed on both sides of the pressure rod 11 moves downward with the pressure rod 11, and when the connecting frame 13 moves downward, it pulls the traction rope 15 to move; the traction rope 15 pulls the magnetic suction frame 16 upward, away from the magnetic suction base 7; after the magnetic suction frame 16 moves upward, the squeezing part 802 loses the restriction of the squeezing head 17, and thus automatically resets, and the clamp head 801 of the clamping part 8 automatically opens;

[0034] Depending on the size of the item to be clamped, the limiting distance of the squeezing head 17 can be adjusted by controlling the pressing distance of the pressing button 3. When a larger opening is required, the pressing button 3 can be pressed down completely, at which point the clamping head 801 opens to its maximum distance. When a smaller opening is required, the pressing distance of the pressing button 3 can be appropriately reduced. All of the above steps can be operated with one hand, and when in the clamping state, there is no need to press with your hand, and your hand is in a relaxed state, making it easy to perform the next operation. When the pressing button 3 is released, the magnetic suction frame 16 automatically resets under the attraction of the magnetic suction base 7, and the squeezing head 17 squeezes the squeezing part 802 of the clamping member 8 again, so that the clamping head 801 clamps the item. There is no need for continuous hand force to maintain the clamping state, saving manpower and improving work efficiency.

[0035] When it is necessary to replace the clamping part 8, rotate the connector 9 fixedly connected to the upper part of the clamping part 8 to rotate the connector 9 out of the connecting groove 10 opened on the bottom surface of the magnetic base 7 to achieve thread separation; remove the old clamping part 8, replace it with the new clamping part 8, and then screw the connector 9 into the connecting groove 10 to fix it.

[0036] The clamping component 8 is made of antibacterial and bacteriostatic materials, which can effectively reduce bacterial growth and improve hygiene and safety when used in the medical field. The surface properties of the silver ion antibacterial material reduce the adhesion between the item and the clamping component 8, and it is not easy for the item to stick even when in contact, further reducing the occurrence of adhesion problems.

[0037] Example 2: Based on Example 1, a buckle is fixedly connected to the upper part of the clamping member 8, and a slot is opened on the bottom surface of the magnetic base 7, and the buckle engages with the slot.

[0038] As can be seen from the above, the buckle fixedly connected to the upper part of the clamping part 8 is pulled out from the slot opened on the bottom surface of the magnetic base 7, the old clamping part 8 is removed, a new clamping part 8 is replaced, and the buckle of the new clamping part 8 is snapped into the slot to achieve fixation.
