Technical Field

[0001] The utility model relates to the technical field of gun pliers, in particular to a gun pliers with a negative pressure suction function. Background Art

[0002] A forceps is a surgical tool used to hold and clamp bones for surgical manipulation. It is usually made of stainless steel for its strength and durability, and is used in areas such as bone repair and plastic surgery.

[0003] In fracture surgery, gun forceps can be used to fix and clamp the two parts of the broken bone, helping doctors to correctly align the bones and fix them together to promote bone repair. During the operation, some dirty fluid, blood and secretions will be produced on the wound surface and around the wound, which are usually cleaned with a separate negative pressure pump. The gun forceps body does not have the function of negative pressure suction, so it is not convenient during the operation. However, if the negative pressure suction function is simply added, when the corresponding parts need to be replaced and disinfected, it is not convenient to switch operations, which reduces the practicality of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The utility model provides the following technical solutions:

[0027] See also Figure 1 A gun clamp with a negative pressure suction function comprises a gun clamp body 1, a switching mechanism 2 is arranged at the bottom of the gun clamp body 1, and a suction mechanism 3 is arranged on one side of the switching mechanism 2.

[0028] See also Figures 2 to 4 The switching mechanism 2 includes a base 21, which is fixedly connected to the bottom of the gun clamp body 1, a side box 22 is fixedly connected to one side of the base 21, a spring 23 is fixedly connected to the inner wall of the side box 22, and a pressure plate 24 is fixedly connected to the end of the spring 23 away from the inner wall of the side box 22. A pull rod 26 is sleeved on the inner ring of the spring 23, and a pull block 27 is fixedly connected to the end of the pull rod 26 away from the pressure plate 24. A connecting block 28 is inserted into the base 21, and a trapezoidal block 25 is fixedly connected to the side of the pressure plate 24 away from the spring 23.

[0029] Furthermore, the pull rod 26 is fixedly connected to one side of the pressure plate 24 close to the spring 23, and the pressure plate 24 is slidably connected to the inner wall of the side box 22, so that the pressure plate 24 can move stably.

[0030] Furthermore, a bayonet is provided on one side of the connection block 28 , and the trapezoidal block 25 is plugged into the inner wall of the bayonet, so that the connection block 28 and the bayonet cooperate with each other to limit the connection block 28 .

[0031] Furthermore, a moving opening matching the trapezoidal block 25 is provided on one side of the base 21, and the trapezoidal block 25 passes through the moving opening, so that the trapezoidal block 25 can move through the moving opening to achieve the purpose of stable limiting.

[0032] Furthermore, a through hole is opened on a side of the side box 22 away from the base 21, and the pull rod 26 passes through the through hole, so that the pull rod 26 can move through the through hole.

[0033] See also Figure 5 and Figure 6 , it is further obtained that the suction mechanism 3 includes a sealing cylinder 31, the sealing cylinder 31 is fixedly connected to the inside of the connecting block 28, the inner wall of the sealing cylinder 31 is movably connected to a piston 32, the left side of the piston 32 is fixedly connected to a movable rod 33, and the left end of the movable rod 33 is fixedly connected to a connecting plate 34, so as to achieve the purpose of negative pressure suction.

[0034] Furthermore, the movable rod 33 passes through the left side of the sealing cylinder 31 and extends into the interior thereof, so that the movable rod 33 can stably pull the piston 32 to move.

[0035] During actual operation, when this device is used, the staff can first pull the connecting plate 34 to the left when it is necessary to absorb dirty liquid or blood during use. The connecting plate 34 drives the piston 32 to move to the left on the inner wall of the sealing tube 31 through the movable rod 33, thereby achieving the purpose of suction and cleaning. The dirty liquid and blood can be sucked into the interior of the sealing tube 31 for collection, ensuring that the wound can heal faster, while promoting blood circulation and improving the convenience of device operation.

[0036] Then, when the suction work is completed, when the sealing cylinder 31 needs to be disassembled and replaced, the good pulling blocks 27 can be pushed close to each other at the same time, so that the pulling block 27 can drive the trapezoidal block 25 to be separated from the inside of the connecting block 28 through the pull rod 26 and the pressure plate 24, and the limit of the connecting block 28 is cancelled. At this time, under the action of gravity, the connecting block 28 will fall from the inside of the base 21, and the sealing cylinder 31 is disassembled. Similarly, the connecting block 28 is aligned with the base 21 and inserted. Since the trapezoidal block 25 is set on an inclined surface, the connecting block 28 can push the trapezoidal block 2 The spring 23 is compressed by moving toward the direction close to the pressing plate 24. When the spring 23 is moved to the direction close to the pressing plate 24, the spring 23 is compressed and will push the pull rod 26 to be inserted into the interior of the connecting block 28 through the pressing plate 24 to limit the position and achieve the purpose of installation. In this way, the gun clamp body 1 is provided with a negative pressure suction function and is convenient for disassembly and assembly switching operations, which further improves the neatness of the device during operation and ensures the efficiency of the disassembly process, thereby reducing the time spent by the staff during operation.
