Description

A new type of pelvic reduction forceps

technical field

The utility model relates to the technical field of medical instruments, in particular to a novel pelvic reduction forceps.

Background technique

Pelvic fracture is a type of fracture that is seriously injured and difficult to treat among limb fractures. It is often caused by high-energy violent injury, such as a patient falling from a high place, or in a car accident, the pelvis is directly injured. Because the pelvis itself is a very strong structure, when this part suffers a particularly severe violent injury, it will cause a corresponding fracture of the pelvis, and the treatment after such a fracture often needs to be delayed until one week after the injury After the systemic stress response is alleviated, it makes it difficult to reset the fracture. It is often necessary to reset the pelvis with the help of various reduction forceps. At present, the main method for reducing and fixing the pelvis is to use various reduction forceps for reduction, Fix the fracture with a plate.

At present, two or more reset pliers are often used at the same time in the process of reset using the reset pliers. During the use, the intersection of the pliers will make the pliers unable to enter the proper position. The use of the retractable pliers can be a good solution. That's the problem.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts all involve the scope of protection of the present utility model.

Example 1

As shown in Figures 1 to 4, this embodiment proposes

In this embodiment, reset pliers 1 are included, the rear end of reset pliers 1 is provided with first handle 2 and second handle 3, the front end of reset pliers 1 is provided with telescopic arm 14 and second pincer head 5, and the front end of telescopic arm 14 is provided with Sleeve 15, the inner side of sleeve pipe 15 is equipped with adjusting rod 16, and the inner side of adjusting rod 16 is provided with locking groove 17, and the end of adjusting rod 16 is provided with first pincer head 4. The length of the first forceps head 4 can be adjusted according to the requirements of the use environment, so as to meet the needs of surgical use.

A locking reed 18 is provided on the inner side of the sleeve 15 , and a locking tooth 19 is provided at the middle section of the locking reed 18 , and the locking tooth 19 can be embedded in the locking groove 17 . During use, the first pliers head 4 may move when it is stressed, and the position of the first pliers head 4 is fixed by using the locking teeth 19 and the locking grooves 17 .

Both the front ends of the first pliers 4 and the second pliers 5 are bent inward at an angle of 90 degrees, and the ends of the first pliers 4 and the second pliers 5 are both sharp structures. The sharp structure can hold the bone tightly, and the inwardly curved angle can gather the force of the forceps head in the middle.

The middle part of the first handle 2 has provided a fixed groove 7 in the middle section, and the inside of the fixed groove 7 is provided with a fixed pin 8, and a fixed rod 9 is movably installed on the fixed pin 8, and the surface of the fixed rod 9 is provided with a screw thread 13. It is used to fix the opening and closing angle of the handle when the forceps head is stressed, and stably reset the bone.

The middle section of the second handle 3 has a fixing hole 10, and the end of the fixing rod 9 runs through the inside of the fixing hole 10, and a nut 11 is installed at the end of the fixing rod 9, and the surface of the nut 11 is provided with anti-slip lines 12. It is used to fix the opening and closing angle of the handle when the reset requirement is met, and the anti-slip pattern 12 can facilitate manual adjustment of the fixing nut 11 .

The first handle 2 and the telescopic arm 14 are an integral body, the middle section has a hole, the second handle 3 and the second pincer head 5 are an integral body, the middle section also has a hole, the first handle 2 and the second handle 3 are cross-movably connected, Rotate and install the swivel pin 6 in the overlapping holes. The way of cross-connection makes the pliers head open when the handle is opened, and the pliers head closes when the handle is closed, which can achieve the purpose of closing bone cracks.

Both the sleeve pipe 15 and the adjusting rod 16 are square structures. The square structure can prevent the first pliers head 4 at the front end from rotating after being stressed.

When getting the reset pliers 1, first observe the use part to determine the length of the first pliers head 4 to be adjusted, and then use the nail of the thumb to toggle the locking spring 18 to drive the locking teeth 19 to break away from the inside of the locking groove 17, and another Adjust the length of the adjustment rod 16 by hand, and when the desired length is reached, release the locking spring 18 to allow it to rebound automatically. Until it can't be moved, it can be used like ordinary reset pliers thereafter.

Example 2
