Description

A kind of fracture positioning forceps

technical field

The utility model relates to a medical device, in particular to a fracture positioning forceps.

Background technique

Accidents or violence are common causes of fractures. In order to restore the integrity and continuity of bones after fractures, it is often necessary to perform effective open reduction and internal fixation on the fracture site. Among them, the most commonly used and most classical fixation method is internal fixation with plate screws. However, in the actual operation process, due to the pulling of the muscles around the fractured end, orthopedic doctors often encounter the instability of the fractured end, and it is necessary to clamp the fractured end with suitable size reduction forceps for temporary reduction Fix the fracture, try to make anatomical reduction of the broken end, and then place a suitable length of steel plate on the surface of the cortical bone on both sides of the broken end. During the reduction, because the reduction forceps are too large to prevent the placement of the steel plates, it is often necessary to remove the reduction forceps before placing them. It is very easy to cause the re-displacement of the fractured end, and repeated displacement will aggravate the soft tissue damage at the fracture site. Therefore, the operator will consider adopting the following solution. After the fracture is fixed with reduction forceps, several Kirschner wires with a diameter of 2 mm to 4 mm are drilled perpendicular to the transverse section of the fracture to temporarily fix the fracture. After the end has been stabilized to a certain extent, place the steel plate. However, often due to the lack of experience of the operator or simple visual inspection, the Kirschner wire cannot be placed in the correct and appropriate direction at one time to reach a satisfactory position, so it is necessary to repeatedly drill the bone canal, which prolongs the operation time and easily causes bone fractures. Destruction of the quality and expansion of the bone canal, resulting in severe fracture splitting.

In view of this, the inventor of the utility model actively develops and studies, and in order to improve the above-mentioned products, through long-term research and experiments, finally develops and designs a kind of fracture positioning forceps of the utility model.

Utility model content

The technical problem to be solved by the utility model is to provide a fracture positioning forceps, which can solve the problem of inaccurate placement of Kirschner wires due to lack of fixation in the prior art.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a fracture positioning forceps, which includes a positioning forceps body, two pliers handles and two pliers heads for operation, and the positioning forceps body includes two hinged forceps handle, at least one of the two pliers heads is provided with a positioning device, the positioning device is an elongated part, and the elongated part is arranged along the closing direction of the two pliers heads, and a hollow passage is provided therethrough.

As a preferred solution, there are two positioning devices, which are respectively arranged on the two pincer heads.

Preferably, the section of the elongated member is a hollow circular tube.

Preferably, the section of the elongated member is a hollow square.

Preferably, the cross section of the hollow channel is circular.

Preferably, the two hinged pliers handles are provided with a movable space around the hinge point, and the hinged shaft can move in the movable space along the closing direction of the two pliers heads.

Preferably, one of the pliers handles is provided with a grid-shaped notch, and the other pliers handle is provided with a protruding clamping rib engaged with the notch.

After adopting the technical solution of the utility model, since at least one of the two clamp heads is provided with a positioning device, after the positioning forceps are placed, the Kirschner wire can be accurately positioned by the positioning device, and the positioning device is a The elongated part is convenient to accommodate and pass through the Kirschner wire. The elongated part is arranged along the closing direction of the two clamp heads, and a hollow passage is provided through it, and the Kirschner wire is precisely positioned through the hollow passage. By adopting the unique design, compared with the prior art, the product of the utility model can achieve multiple practical advancements such as accurate positioning, reduced fixing times, and increased firmness.

Detailed ways

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Please refer to Fig. 1 and Fig. 2, which are specific embodiments of a fracture location forceps of the present invention. A kind of fracture positioning forceps, it comprises positioning forceps main body 1, and two forceps handles and two forceps heads 3 for operation, are used for clamping the two ends of fracture site, and described positioning forceps body comprises two hinged forceps handles 2. It is convenient to accommodate fingers for the operation of positioning pliers. At least one of the two pliers 3 is provided with a positioning device 4, the positioning device 4 is an elongated part, the elongated part is arranged along the closing direction of the two pliers, and a hollow passage 7 is provided through it, In this way, the Kirschner wires can be accurately passed through the hollow channel 7 of the positioning device to realize the fixation of the fracture site. In practice, a kind of implementation is: the hollow channel is about 1.5cm long, and its diameter is set to 1.55mm, which is convenient for the diameter of A 1.5mm Kirschner wire can pass through, and the diameter of the hollow channel can also be selected to be slightly larger than 3mm, so that a 3mm thick Kirschner wire can pass through to locate the fracture site.

The setting of the hollow pipe 7 of the utility model can play the role of guiding and positioning, which is more convenient to use, and can play a guiding role when drilling into the Kirschner wire, without deviation, accurate and convenient, and reduces the operation time. Alleviate the suffering of patients.

As a preferred solution, there are two positioning devices, which are respectively arranged on the two pincer heads, so as to realize fracture positioning at both ends of the pincer heads.

The cross-section of the elongated part is selected as a hollow circular tube, which is convenient for matching with a Kirschner wire with a circular diameter.

In another embodiment, the cross-section of the elongated part is set as a hollow square, and its shape does not affect the passage of the elongated part through the patient's part, and the interior of the elongated part can also pass through the Kirschner wires whose diameter is smaller than its side length, so as to realize Localization of the fracture site.

As a preferred embodiment, the cross section of the hollow channel 7 is circular, which is convenient for matching with a Kirschner wire with a circular diameter.

The two hinged pliers handles are provided with a movable space around the hinge point, and the hinged shaft can move along the closing direction of the two pliers heads in the movable space, so that when it is necessary to expand the working space of the two pliers heads, you can choose Move the hinge point to adjust the size of the opening between the two clamp heads.
