Description

Fixing device for bone traction

Technical Field

The utility model relates to the field of medical equipment, concretely relates to fixing device for bone traction.

Background

Bone traction is an operation method for temporarily fixing a patient limb fracture part, and is widely applied to clinic. The bone traction surgical instrument commonly used at present is a bone traction apparatus which mainly comprises a bone traction bow and a bone traction needle, wherein the bone traction bow can be repeatedly used. When the bone traction operation needs to be implemented, a doctor opens a bone traction bag which is internally provided with surgical instruments of various specifications, such as bone traction needles, hand drills or electric drills, and the like, and then carries out sterilization, disinfection and positioning. During operation, a bone traction needle with a proper specification is screwed into a positioning point, close to a fracture part, on a patient limb by a hand drill or an electric drill until cortex on two sides is screwed through and skin is punctured from the other side to penetrate out, then two ends of the bone traction needle are connected with a bone traction bow, the length of the bone traction needle is trimmed according to the size of the patient limb, and the needle tip and the needle tail are bent and wrapped to prevent secondary injury.

However, the prior bone distractors have been found to suffer from the following problems in use: firstly, the patient inevitably has limb movement in the bone traction process, so that the traction needle is deviated from the original position, and the probability of skin infection at the needle hole is easily increased; secondly, after the traction needle is deviated, the original position needs to be manually adjusted and restored, and the operation is repeatedly adjusted, so that the pain of the patient is increased, and great psychological negative influence is caused to the patient; the infection chance is increased, the bone healing is affected, and the hospitalization time is prolonged; resulting in the displacement of fracture ends and the healing of deformity, and having great influence on the disease prognosis of patients.

In order to prevent the traction needle from sliding, a common measure at present is to pad towels on two sides of the traction needle hole, but the following problems also exist in doing so: firstly, the towel pad is not stable enough, and the traction needle is still easy to deviate; secondly, the towel is padded on the two sides of the needle hole, so that the sanitation and the disinfection are not up to the standard, and the wound infection is easily caused.

Drawings

The invention will be further described with reference to the following drawings and examples:

fig. 1 is a schematic structural diagram of a first embodiment of the present invention.

Wherein: 1. a base; 2. an outer support; 3. an inner support; 4. a needle holder; 5. a needle groove; 6. and fastening the bolt.

Detailed Description

Example (b): referring to fig. 1, the fixing device for bone traction comprises a fixing device body, wherein the fixing device body is composed of a base 1, an outer support 2, an inner support 3 and a needle support 4, the upper surface of the base 1 is fixedly connected with the bottom end of the outer support 2, the upper end of the inner support 3 is fixedly connected with the bottom of the needle support 4, the inner support 3 is arranged inside the outer support 2 and can vertically slide along the outer support to form a lifting sliding connection between the inner support and the outer support, a fastening bolt 6 is arranged outside the outer support 2 in a penetrating manner in cooperation with the inner support 3, and a needle groove 5 matched with a traction needle of the bone traction device is formed in the upper surface of the needle support 4.
