Problems solved by technology

[0003] At present, the traction operation is mainly done by the surgeon based on experience, and has the following defects: (1) The puncture site is not constant, which easily hurts the blood vessels and nerves, causing continuous pain; (2) It is impossible to ensure that the steel needle is always perpendicular to the bone surface during the puncture process, resulting in The puncture needle is not perpendicular to the force line of the lower limbs, and the traction force line deviates, causing discomfort to the patient; (3) The patient's foot is not fixed during the puncture process, and shaking will aggravate the pain at the original fracture site, and at the same time cause the angle deviation of the puncture needle

Embodiment Construction

[0070]The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0071] according to Figure 1-Figure 9 A calcaneal traction navigation device shown is composed of a device body 1, a guide rail, a guide rail sleeve 2, a positioning sleeve 3, a puncture needle sleeve 4, an anti-stab cap 5, a retractor 6, a base 7 and a puncture needle 8 composition.

[0072] The device body 1 includes a curved supporting plate with a し-shaped curved radian, that is, the curved surface of the foot is designed to fit the shape of the foot, and the upward extension of the curved supporting plate has a direction indicator 13, which is convenient for confirmation during actual use. Direction, to ensure that the patient's pin is fixed correctly, can be a common marking form, such as a sticker, preferably an arrow-type direction indicating groove in the present invention, and when the traction device is fixed, the arrow-type indicat...

Abstract

The invention relates to a calcaneus traction navigation device. The calcaneus traction navigation device is characterized by comprising a device body, guide rails, guide rail sleeves, a positioning sleeve, puncture needle sleeves, a puncture needle, a base and a tractor. The calcaneus traction navigation device has the beneficial effects that the calcaneus traction navigation device can be freely adjusted so that suitable puncture points can be selected; due to the combined shape of the device, the double-fixing effect is formed; in the puncturing process, a steel needle is always vertical to the bone surface; and the feet of a patient are fixedly firmly.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and relates to a device for calcaneal traction and navigation. Background technique [0002] In daily medical activities, calcaneal tuberosity traction is a very commonly used bone traction technique, mainly used for tibial plateau fractures, unstable fractures, open tibial fractures, and comminuted fractures. Through the midpoint of the line connecting the tip of the ankle and the rear lower edge of the heel, pass through the calcaneus from the inside to the outside, and pass a steel needle, and apply traction weight through the steel needle. [0003] At present, the traction operation is mainly done by the operator based on experience, and has the following defects: (1) The puncture site is not constant, which is easy to injure blood vessels and nerves, causing continuous pain; (2) It is impossible to ensure that the steel needle is always perpendicular to the bone surface during th...
