Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and more specifically, to a biological tissue clamp that prevents loosening. Background Technology
[0002] Tissues are cellular structures situated between cells and organs, composed of many morphologically similar cells and intercellular matrix. Therefore, they are also called biological tissues, and biological tissue holders are clamps used to hold biological tissues. Biological tissue holders are often used in the medical industry, such as in basic surgery, where they are used to hold and lift tissues to facilitate dissection and suturing, and can also hold suture needles and dressings.
[0003] However, most existing biological tissue holders rely on hand pressure to clamp the biological tissue with two clamping points. Prolonged hand pressure can cause hand fatigue or tremors, so if the hand loosens its grip during the clamping process, the clamping points will loosen their grip on the biological tissue.
[0004] Therefore, a biological tissue clamp designed to prevent loosening is proposed to address the above-mentioned problems. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a biological tissue clamp that prevents loosening, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a biological tissue clamp that prevents loosening, comprising a handheld rod, two fixed seats symmetrically fixedly connected to the top of the handheld rod, a connecting shaft fixedly disposed between the two fixed seats, two connecting bases rotatably sleeved on the outside of the connecting shaft, a torsion spring movably sleeved on the outside of the connecting shaft, a fixing component disposed at one end of each of the two connecting bases, and a clamping component connected to one end of each of the two connecting bases through the fixing component, a locking cylinder threadedly connected to the upper outer side of the handheld rod, an internal thread disposed on the inner side wall of the locking cylinder, and an external thread disposed on the outer side wall of the handheld rod that is threadedly connected to the locking cylinder.
[0007] Preferably, one end of the locking cylinder is fixedly connected to a rotary knob for adjusting the rotation of the locking cylinder, and the outer side of the rotary knob is provided with rough texture to increase the friction between the hand and the rotary knob.
[0008] Preferably, the fixing component includes a connecting block, a screw, a threaded connecting hole, and a notch. Each of the two clamping components is fixedly connected to a connecting block at one end. The two connecting blocks have two threaded connecting holes symmetrically opened on their side walls. The two connecting blocks are limited and set inside the connecting base. The two connecting bases have two notches on their side walls. The screw passes through the notch and is threaded into the threaded connecting hole.
[0009] Preferably, the spacing between the two threaded connection holes is the same as the spacing between the two missing holes.
[0010] Preferably, a handheld button is fixedly connected to the bottom end of the handheld lever, and the outer wall of the handheld button is provided with rough texture.
[0011] Preferably, a plug is screwed onto the top of the locking cylinder, and the plug has an external thread on its outer side that engages with the internal thread of the inner wall of the locking cylinder. A rotating block for rotating the plug is fixedly connected to the surface of the plug.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. Compared with the prior art, the position of the locking cylinder on the handheld rod can be adjusted by the screw connection between the handheld rod and the locking cylinder. The locking cylinder, whose position can be adjusted, locks and limits the two connecting bases and the clamping components set on the connecting bases to clamp the biological tissue, preventing the two clamping components from loosening when clamping the biological tissue and improving the stability of the two clamping components when clamping the biological tissue.
[0014] 2. Compared with the existing technology, the connecting block and the clamping components of different sizes fixed on the connecting block can be disassembled and replaced. When not in use, the two clamping components can be stored in the connecting base in reverse, and then the locking cylinder on the hand handle can be rotated to store the two connecting bases into the locking cylinder. Finally, the plug on the locking cylinder is closed, which facilitates the storage and protection of the clamping components and the carrying of the entire device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] As attached Figures 1 to 5 The illustrated anti-loosening biological tissue clamp includes a handheld rod 1. Two fixed seats 3 are symmetrically fixedly connected to the top of the handheld rod 1. A connecting shaft 4 is fixedly arranged between the two fixed seats 3. Two connecting bases 5 are rotatably sleeved on the outside of the connecting shaft 4. A torsion spring 6 is movably sleeved on the outside of the connecting shaft 4. A fixing component is provided at one end of each of the two connecting bases 5. A clamping component 8 is connected to one end of each of the two connecting bases 5 through the fixing component. A locking cylinder 2 is threadedly screwed onto the outer side of the upper end of the handheld rod 1. The inner side wall of the locking cylinder 2 is provided with an internal thread. The outer side wall of the handheld rod 1 is provided with an external thread that is screwed onto the locking cylinder 2. A rotary knob 12 for adjusting the rotation of the locking cylinder 2 is fixedly connected to one end of the locking cylinder 2. The outer side of the rotary knob 12 is provided with a rough texture to increase the friction between the hand and the rotary knob 12. Finally, a handheld knob 13 is fixedly connected to the bottom end of the handheld rod 1.
[0024] In use, the locking cylinder 2 is first adjusted by rotating the knob 12. Then, the locking cylinder 2 is screwed onto the hand lever 1, allowing it to move and adjust on the hand lever 1. As the locking cylinder 2 moves, the connecting base 5 causes one end of the two clamping components 8 to move closer to each other, thereby clamping the biological tissue. At this time, the torsion spring 6 deforms due to the rotation and compression of the two connecting bases 5. The threaded connection between the hand lever 1 and the locking cylinder 2 has a certain self-locking property, thus locking the position of the locking cylinder 2 on the hand lever 1. The locked position of the locking cylinder 2 locks and limits the two connecting bases 5 and the clamping components 8 that clamp the biological tissue on the connecting bases 5, thereby preventing the two clamping components 8 from loosening when clamping the biological tissue and improving the stability of the two clamping components 8 when clamping the biological tissue.
[0025] Example 2
[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:
[0027] In a preferred embodiment, the fixing assembly includes a connecting block 7, a screw 9, a threaded connecting hole 10, and a notch 11. First, a connecting block 7 is fixedly connected to one end of each of the two clamping components 8. Then, two threaded connecting holes 10 are symmetrically formed on the sidewalls of the two connecting blocks 7. The two connecting blocks 7 are positioned within the connecting base 5, and two notches 11 are formed on the sidewalls of the two connecting bases 5. Finally, the screw 9 passes through the notch 11 and is threaded into the threaded connecting hole 10. Further, the two connecting blocks 7 and the clamping components 8 on the two connecting blocks 7 can be fixed, installed, or removed. When replacing, first turn the two screws 9 to release the limiting fixation between the connecting block 7 and the connecting base 5. Then replace the clamping part 8 with the required size or shape, and then fix the connecting base 5 and the connecting block 7 with the screws 9. At this time, the clamping part 8 extends out of the connecting base 5 relative to the connecting base 5. When it is not needed, the direction of the clamping part 8 can be reversed so that the clamping part 8 can be stored and folded into the connecting base 5. Then, similarly, fix the limiting fixation between the connecting base 5 and the connecting block 7 with the two screws 9 so that the clamping part 8 can be stably stored and folded into the connecting base 5.
[0028] In a preferred embodiment, a plug 14 is screwed onto the top of the locking cylinder 2. The plug 14 has an external thread that engages with the internal thread of the inner wall of the locking cylinder 2. A rotating block 15 is fixedly connected to the surface of the plug 14 to rotate the plug 14. Furthermore, the locking cylinder 2 on the hand lever 1 can be rotated to completely retract and move the two connecting bases 5 and the clamping component 8, which is folded into the two connecting bases 5, into the locking cylinder 2. Then, the plug 14 is screwed onto one end of the locking cylinder 2 by the rotating block 15, thereby forming a closed space inside the locking cylinder 2.
[0029] The working process of this utility model is as follows: First, the locking cylinder 2 is adjusted by rotating the knob 12. The locking cylinder 2 is screwed into the hand handle 1, which allows the locking cylinder 2 to move and adjust on the hand handle 1. As the locking cylinder 2 moves, the connecting base 5 drives one end of the two clamping components 8 to move closer to each other, thereby clamping the biological tissue. At this time, the torsion spring 6 is deformed due to the rotation and compression of the two connecting bases 5. The screwed connection between the hand handle 1 and the locking cylinder 2 has a certain self-locking property, thereby locking the position of the locking cylinder 2 on the hand handle 1. The locking cylinder 2 in the locked position locks and limits the two connecting bases 5 and the clamping components 8 set on the connecting bases 5 to clamp the biological tissue, thereby preventing the two clamping components 8 from loosening when clamping the biological tissue and improving the stability of the two clamping components 8 when clamping the biological tissue.
[0030] When it is necessary to fix or disassemble / replace the two connecting blocks 7 and the clamping parts 8 set on the two connecting blocks 7, first turn the two screws 9 to release the limiting fixation between the connecting blocks 7 and the connecting base 5. Then, replace the clamping parts 8 with the required size or shape, and then fix the connecting base 5 and the connecting blocks 7 with the screws 9. At this time, the clamping parts 8 are protruding from the connecting base 5 relative to the connecting base 5. When not in use, the direction of the clamping parts 8 can be reversed so that the clamping parts 8 are stored and folded into the connecting base 5. Then, similarly, the limiting fixation between the connecting base 5 and the connecting blocks 7 is made with the two screws 9 so that the clamping parts 8 can be stably stored and folded into the connecting base 5. Next, continue to turn the locking cylinder 2 on the hand lever 1 so that the two connecting bases 5 and the clamping parts 8 stored and folded into the two connecting bases 5 are completely stored and moved into the locking cylinder 2. Finally, the plug 14 is screwed into one end of the locking cylinder 2 by rotating the block 15. The above is the working principle of this kind of anti-loosening biological tissue clamp.
