[0003] There are many existing technologies for hemostatic forceps, such as:

[0004] Chinese patent publication number CN214157429U discloses an elbow hemostatic forceps, which includes a grip A and a grip B. A grip hole A is provided on the surface of the grip A, and a grip hole B is provided on the surface of the grip B. A fixed block is fixedly connected to the bottom surface of the grip A, a hinge is installed on one side surface of the fixed block, and one side surface of the fixed block is hinged to a rotating piece through the hinge. An adjusting spring is installed on one side surface of the fixed block, and one end of the adjusting spring away from the fixed block is fixedly connected to the rotating piece, and the rotating piece is movably connected to the fixed block through the adjusting spring. Two groups of rotating pieces are provided, and the two groups of rotating pieces are mirror-imaged with the fixed block as the center. The two groups of rotating pieces can stably fix the hemostatic angle of the hemostatic forceps, prevent the inconvenience of hemostasis caused by hand shaking, improve the hemostatic effect of the hemostatic forceps, and meet the use requirements.

[0005] Most of the existing hemostatic forceps do not have a structure that facilitates assistance when in use. If you cannot pick up the required items by clamping with one hand during use, and the conditions are limited, the existing hemostatic forceps are difficult to operate with both hands, and when the hemostatic forceps are clamped with one hand for a long time, the hand is prone to soreness, which affects the use. At the same time, although the above-mentioned hemostatic forceps have a compression adjustment spring to assist in opening the hemostatic forceps when in use, the adjustment spring cannot adjust the elastic force of the compression adjustment spring according to the use requirements, which reduces the practicality of the hemostatic forceps.

[0006] In view of this, we propose an elbow hemostatic forceps, which ensures that the hemostatic forceps will not loosen the clamped object without applying additional pressure after clamping at a certain angle through a one-way fixing component, and adjusts the tightness of the spring through a tension adjustment component.

[0027] Example

[0028] See also Figure 1-Figure 6 As shown, this embodiment provides an elbow hemostatic forceps, including a supporting assembly 10, the supporting assembly 10 includes a main arm 11 and an auxiliary arm 12, the main arm 11 and the auxiliary arm 12 are each provided with a socket at the top, a rotating rod 13 is inserted into the two sockets, the main arm 11 and the auxiliary arm 12 are rotatably connected by the rotating rod 13, a sliding groove 14 is provided on the side away from the main arm 11 and the auxiliary arm 12, a one-way fixing assembly 40 is provided on the top of the rotating rod 13, the one-way fixing assembly 40 is used to prevent the clamped object from being clamped tighter without applying pressure to the main arm 11 and the auxiliary arm 12 again, a tension adjustment assembly 30 is slidably connected in the sliding groove 14, the tension adjustment assembly 30 is used to adjust the tightness of the main arm 11 and the auxiliary arm 12 when they rotate, and a plug-in assembly 20 is provided at the end of the main arm 11 and the auxiliary arm 12, and the plug-in assembly 20 is used to adapt to hemostatic forceps arms of different sizes.

[0029] Working principle: When the elbow hemostatic forceps provided by the utility model are used, the one-way fixing component 40 is provided to prevent the clamped object from being clamped tighter without applying pressure to the main arm 11 and the auxiliary arm 12 again, and the tightness of the main arm 11 and the auxiliary arm 12 when rotating is adjusted by the tension adjustment component 30, and then the plug-in component 20 is used to adapt to hemostatic forceps arms of different sizes.

[0030] In order to adapt to hemostatic forceps arms of different sizes and prevent the clamped object from being clamped tighter, the plug-in assembly 20 includes a pair of clamp arms 21 and slots 22 opened at the ends of the main arm 11 and the auxiliary arm 12. A plug 23 is provided on the side of the clamp arm 21 close to the main arm 11 and the auxiliary arm 12. The plug 23 is plugged into the slot 22, and a bolt 24 is threadedly connected between the slot 22 and the plug 23. When performing different operations on patients, the sizes of hemostatic forceps required to be used are different due to the different locations of the lesions in the patients. Before the operation, according to the specific surgical site of the patient, a clamp arm 21 of a suitable size is selected and installed at the ends of the main arm 11 and the auxiliary arm 12, and then the bolt 24 is screwed into the threaded groove of the plug 23 and the slot 22, so as to ensure the consistency of force transmission between the clamp arm 21 and the main arm 11 and the auxiliary arm 12.

[0031] Taking into account the need to adjust the tightness of the main arm 11 and the auxiliary arm 12 when they rotate, the tension adjustment component 30 includes a pair of adjustment blocks 31 slidably connected to the two slide grooves 14, the tops of the two adjustment blocks 31 are threadedly connected to the limit seats 32, and an adjustment spring 33 is fixedly connected between the two limit seats 32; when the user feels hand soreness due to holding the hemostatic forceps for a long time, the position of the sliding adjustment block 31 in the slide groove 14 is changed to change the distance between the two limit seats 32, thereby changing the tightness of the adjustment spring 33. In addition, the contact parts of the adjustment block 31 and the slide groove 14 are arranged to be serrated, so as to prevent the adjustment block 31 from deviating from the original position due to excessive external force after determining the position in the slide groove 14.

[0032] In order to achieve the situation where no pressure is applied to the main arm 11 and the auxiliary arm 12 again, the one-way fixing assembly 40 includes a ratchet 41 rotatably connected to the top of the rotating rod 13, a fixing frame 42 is provided on the periphery of the ratchet 41, the fixing frame 42 is fixedly connected to the top of the main arm 11, a plurality of ratchet pawls 43 are rotatably connected to the inner side of the fixing frame 42, and the ends of the plurality of ratchet pawls 43 away from the fixing frame 42 are all engaged with the outer ring of the ratchet 41; the ratchet 41 is fixed by a central axis, and its outer ring has a series of ratchet teeth arranged at uniform intervals. When an external force acts on the ratchet 41, the ratchet teeth will start to rotate due to the torque. The special shape of the ratchet teeth makes them rotate only in one direction and be blocked in the other direction. When the ratchet 41 rotates, they will pass through the ratchet teeth adjacent to it one by one. This transmission mode effectively transmits the input torque to the next ratchet tooth to realize the transmission of power. This transmission mode of transmitting only one ratchet tooth at a time makes the ratchet 41 have higher accuracy and stability when transmitting power.

[0033] In order to increase the friction force of the adjustment block 31 in the slide groove 14, the adjustment block 31 and the adjustment spring 33 are both made of polyurethane; polyurethane is a multi-purpose synthetic material with good wear resistance and elasticity, and is often used in making products that are in contact with the human body. It can adjust the hardness and elasticity to meet different needs, and has good corrosion resistance.

[0034] When the elbow hemostatic forceps provided in the utility model are used, the one-way fixing assembly 40 is provided to prevent the clamped object from being clamped tighter without applying pressure to the main arm 11 and the auxiliary arm 12 again. Specifically, the ratchet 41 is fixed by a central axis, and its outer ring has a series of ratchet teeth arranged evenly at intervals. When an external force acts on the ratchet 41, the ratchet teeth will be acted upon by the torque and start. The special shape of the ratchet teeth makes them only able to rotate in one direction and be blocked in the other direction. When the ratchet 41 rotates, they will pass through the adjacent ratchet teeth one by one. This transmission mode effectively transmits the input torque to the next ratchet tooth to realize the transmission of power. This transmission mode of transmitting only one ratchet tooth at a time makes the ratchet 41 have higher accuracy and stability when transmitting power. The tightness of the main arm 11 and the auxiliary arm 12 when rotating is adjusted by the tension adjustment assembly 30. Specifically, When the user feels hand pain due to holding the hemostat for a long time, the user can slide the adjustment block 31 in the slide groove 14 to change the distance between the two limit seats 32, thereby changing the tightness of the adjustment spring 33. In addition, the contacting parts of the adjustment block 31 and the slide groove 14 are all set to be serrated, so as to prevent the adjustment block 31 from deviating from the original position due to excessive external force after determining the position in the slide groove 14; the plug-in assembly 20 is used to adapt to different sizes of hemostat arms. Specifically, when performing different operations on patients, the sizes of hemostat to be used are different due to different lesion sites of the patients. Before the operation, according to the specific surgical site of the patient, a clamp arm 21 of appropriate size is selected and installed at the ends of the main arm 11 and the auxiliary arm 12, and then the bolt 24 is screwed into the threaded groove of the plug 23 and the slot 22, so as to ensure the consistency of force transmission between the clamp arm 21 and the main arm 11 and the auxiliary arm 12.
