Problems solved by technology

[0002] When performing fracture surgery, according to the fracture location and injury status of the patient, it is necessary to reset and maintain the fractured bone and fix it with drilling nails. Because most of the drilling nails are drilled directly without guidance and based on the experience of the surgeon, the surrounding area The coverage of soft tissue is difficult to observe, and it is impossible to enter in the ideal channel, which will easily lead to the unsatisfactory channel of the drill nail and the deviation of the hole. After X-ray observation, the position is often not ideal, and the screw needs to be pulled out before drilling. Screws are placed, which increases the surgical trauma and prolongs the operation time
[0003] However, the existing fixed and clamping equipment has a single function and can only achieve a single clamping operation, especially when the patella fracture requires steel nails to be fixed in the required position and direction, but there is no guiding and navigation device, which is prone to drilling deviation. It not only affects the efficiency and quality of the operation, but also causes damage to the patient. For this reason, a clamping and guiding device for orthopedic surgery is needed

Embodiment 1

[0044] The fixing assembly 4 includes a pillar 401 fixedly connected to one of the hand-held rods 202, the outer ring of the pillar 401 is movably socketed with a first pull rod 402, and the end of the first pull rod 402 away from the pillar 401 is movably socketed with the adjacent handle rod 202 The outer side of the hand-held rod 202 provided with the pillar 401 is provided with a limiting plate 403 of L-shaped structure, and the limiting plate 403 is located on the side where the two groups of hand-held rods 202 are far away from each other, and the side of the limiting plate 403 close to the adjacent hand-held rods 202 is provided with a The blocking teeth are equidistantly arranged along the length direction of the handle bar 202. The end of the first pull rod 402 close to the limiting plate 403 is provided with a docking slot arranged in an array along the axis of the pillar 401, and the docking slot is engaged with the blocking tooth. The two sides of the pillar 401 Bot...

Embodiment 2

[0046] The pushing part includes a pushing plate fixedly connected to the limiting plate 403 , a finger loop is fixedly connected to the end of the handle bar 202 away from the rotating plate 201 , and the pushing plate extends to the position of the adjacent finger loop.

Embodiment 3

[0048] The guide assembly 5 includes a contact rod fixedly connected to the rotating shaft 209. A guide channel is provided in the middle of the contact rod along its length direction. The two groups of contact rods are arranged along the same axis, and the ends of the two groups of contact rods that are close to each other are provided with sawtooth Shaped clamping groove, the clamping groove makes it firmly clamped with the patient, the side of the guide plate 103 adjacent to the rotating plate 201 is provided with a circular arc-shaped extrusion channel 104, and the extrusion channel 104 and the pull rod 211 are movable Socketing, the distance between the extrusion channel 104 and the axis of the guide plate 103 gradually increases along its length direction.

[0049] Working principle: when clamping, first put the thumb into the finger ring on the handle bar 202 with the pillar 401 installed, and at the same time the end of the thumb is close to the push plate of the pushin...

Abstract

The invention belongs to the technical field of orthopaedics apparatuses, in particular to a navigation device for clamping a drilling nail, for orthopaedics surgeries. The navigation device is characterized by comprising a supporting assembly, and two groups of clamping assemblies, wherein the supporting assembly comprises a supporting sleeve ring adopting an annular structure and a supporting shaft which is fixedly connected to the inner ring of the supporting sleeve ring; the two groups of guiding disks which are arranged in parallel are fixedly connected to the outer ring of the supportingshaft in a sleeving manner; the two groups of the clamping assemblies are movably connected with the supporting shaft in a sleeving manner, and are provided with a fixing assembly for fixing and guiding assemblies for guiding; the two groups of the clamping assemblies are distributed in the shape of scissors by using the supporting shaft as an axis. Through the adoption of the navigation device disclosed by the invention, the patient can be conveniently clamped and fixed to realize binding and fixing from the top of the front surface, so that the navigation device is suitable for clamping different positions particularly clamping of the side position, so that the two groups of guiding assemblies are still in the same straight line, operations of opening a pore and threading are convenientto perform for the patient, the surgery quality is improved, the operation difficulty of medical personnel is alleviated, and the efficiency and the quality of the surgery are improved.
