Nail taking-out device for department of orthopedics

Abstract

The invention relates to the technical field of medical instruments, and discloses a nail taking-out device for the department of orthopedics. The nail taking-out device comprises a third motor. According to the nail taking-out device, the third motor is controlled to operate to enable a cutter wheel at the top of an output shaft of the third motor to be rotated, a groove can be cut out on the side face of a broken nail, after the groove is cut out, a sliding part is controlled to move to enable the broken nail to be located between a fixing block and a pressing plate, then a second motor is controlled to operate to enable the pressing plate to move inwards, a clamping block on the pressing plate is also clamped into the punched groove, the broken nail is clamped into a nail groove in thefixing block, at the moment, a rotating motor is controlled to operate, and thereby the broken nail can be slowly screwed out. The nail taking-out is simpler and more convenient, and because only theside face of the broken nail has the groove, the clamping block can be clamped in the groove without slipping, and thereby the nail taking-out effect is better. A negative pressure fan is operated tobe capable of absorbing metal chippings, generated during the broken nail is cut, through a negative pressure, the metal chippings are stored in a cloth bag through a conical groove and a cleaning groove, the metal chippings can be prevented from being scattered on a wound of a patient, and thereby the nail taking-out is safer.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an orthopedic nail remover. Background technique [0002] In clinical medicine, fracture is one of the common diseases of bone trauma. The method often used to treat fractures is to implement internal fixation surgery, that is, after the fracture site is reset, the bone plate and bone nails made of metal materials are used to fix the bone after reduction. connect them. [0003] When bone nails are used to fix bones, the broken nails often occur. When the broken nails occur, the operation is forced to stop, and the whole process of fracture fixation has to start from the beginning. The removal of broken nails is a very troublesome thing, time-consuming and labor-intensive. The traditional tool for removing broken nails is a ring-saw shape. The risk of refracture increases, the operation time is increased, the patient has more bleeding, and the chance of postoperative inf...

AI Technical Summary

Problems solved by technology

However, in practical application, we found that the above-mentioned nail remover still has certain deficiencies. For example, the technology of the above-mentioned nail remover is to ring groove the broken nail, and use the groove to take out the broken nail after the ring is grooved. , but among them, there are a few problems that have not been solved. For example, it is troublesome to perform ring grooving on broken nails, which is a waste of time and wears on the blades. Moreover, when rotating broken nails, the holding force of ring grooving It is small and easy to slip. Also, metal debris will be produced when the broken nail is ring grooved. If these debris cannot be cleaned in time, there will be a great safety hazard if it falls into the patient's wound
