Description

A K-wire reset adjustment device

technical field

The utility model relates to the field of medical instruments, in particular to a Kirschner wire reset adjusting device. technical field

Kirschner wire is a commonly used internal fixation device in orthopaedics. It is simple and convenient.

In orthopaedics and surgery, medical workers often use Kirschner wires to fix the fracture ends when treating patients with fractures. Fractures with little stress such as avulsion fractures or short fractures are fixed. In specific surgical operations, the penetration point and direction of Kirschner wire are all based on the experience of medical workers, which leads to deviations in the perforation position during surgery. Problems such as the low success rate of one-time needle threading increase the risk and pain of surgery for patients. It is often necessary to set a certain angle to fix the fracture end with Kirschner wire. In conventional treatment, the setting of different angles is often determined by the doctor's own experience, which cannot be accurate. Positioning, if there is an angle deviation, simply tapping the K-wire to adjust may cause the K-wire to break. For this purpose, a tool is needed to assist.

Utility model content

The utility model provides a Kirschner wire repositioning and adjusting device, which is used to provide medical staff with deviation in the angle after the Kirschner wire is inserted, so as to assist the medical staff in correcting the angle.

A K-wire reduction and adjustment device, comprising a curved plate,

The curved plate is provided with through holes for implanting Kirschner wires,

A handle is provided on the curved plate,

The handle rotates the curved plate after the curved plate is locked with the bone.

Preferably, both ends of the curved plate are provided with bending parts, which are fixed with additional bending parts, which play a role of secondary fixing and strengthen the fixing effect.

Preferably, the edge of the curved plate is provided with serrations that increase frictional force, so as to avoid the phenomenon of sliding between the curved plate and the bone after fixing.

Preferably, the surface of the curved plate is provided with a knocking groove, which provides a knocking groove for assisting the medical staff to strike a position.

Preferably, there is a gap between the through holes, and a corresponding space is provided when multiple K-wires are inserted.

Preferably, the cross section of the handle is arc-shaped, which is convenient for medical staff to hold and reduces discomfort on the hands of medical staff.

Preferably, the handle is located at the geometric center of the curved plate, and is arranged at the geometric center to receive uniform force, so as to ensure that there is no deviation in the force during the adjustment operation.

Preferably, there is a depression at the location of the through hole, which can clearly indicate the location of the through hole, which is convenient for medical staff to find.

Compared with the prior art, after adopting the above structure, the utility model has the following advantages:

1. The structure of the device is simple, the operation and storage are convenient, and it is not easy to make mistakes under the tense atmosphere during the operation;

2. The curved plate is close to the bone, and the Kirschner wire is inserted into the bone through the curved plate at the same time. Compared with the phenomenon that the Kirschner wire is easily broken by simply tapping the curved plate, the Kirschner wire can be fine-tuned by tapping the curved plate. The needles are not prone to breakage and bending, which is more conducive to surgical treatment.

Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings.

A Kirschner wire reset adjustment device, comprising a curved plate, the curved plate is provided with a through hole for K-wire implantation

A handle is provided on the curved plate, and the handle rotates the curved plate after the curved plate is locked with the bone.

Further, in the present invention, the main body is a curved plate, the curved plate is attached to the damaged part of the patient's bone, and the curved plate is in a curved shape, in order to fit the overall shape of the bone.

Further, referring to FIG. 1, FIG. 1 shows another embodiment. The curved plate is still curved as a whole, but a vertical bending part is used at the tail end. If the two sides of the bone are flat, the completely curved clamping plate is not very effective, and a curved plate with a bending part is used, which is more suitable for the bone plate at this time, which is more conducive to the operation.

Further, in the present invention, the Kirschner wire is implanted into the bone through the through holes provided on the curved plate, the through holes are arranged along the circumferential direction of the curved plate, and a number of through holes are arranged, and each through hole is separated by a certain distance. It has been proved that the separation of 4 to 6 mm is the best.

Further, in the present invention, the aforementioned through holes are provided for the purpose of matching the K-wires, so the overall hole diameter will not be too large, so sometimes it is difficult to identify and search for the phenomenon, therefore, the position of the through hole is provided with a The depression is used to indicate the location of the through hole. At the same time, in order to further enhance the reminder effect, a sequin is arranged on the inner edge of the depression. The purpose of the sequins is that when the operating light is illuminated, reflection will occur, thereby prompting medical staff that there is a through hole here. Or rather, the vias exist here.

Further, in the present utility model, the cross-section of the handle is arc-shaped, the handle is located at the geometric center of the curved plate, and the arc-shaped handle is beneficial for medical staff to hold, and is beneficial to medical staff. operation can make the operation more convenient.

Further, in the present utility model, the handle is located at the geometric center of the curved plate. Since it is necessary to hold the handle when knocking, if the position of the handle is not located at the center, it is easy to break the process of surgery.

To sum up, the working principle of the present utility model is as follows: the medical staff holds the handle, and after placing the curved part on the patient's skeletal lesion, the arc surface of the curved plate matches the shape of the bone. The surface of the plate is provided with serrations that increase the friction force with the bone surface, which has a certain anti-slip effect. At this time, the Kirschner wire is implanted through the through hole. If it is found that the Kirschner wire needs to be adjusted after insertion, then The Kirschner wire is slightly adjusted by tapping the tapping groove. Since the bending plate has been in close contact with the bone at this time, the Kirschner wire is implanted in the bone again. For the whole Kirschner wire, most of the needle body is already bent. In the plate and bone, the adjustment is performed by holding the handle by hand, as opposed to simply tapping the K-wire.
