Embodiment 1

[0037] Such as figure 1As shown, the present invention provides a laser device for orthopedic surgery, including: combined action unit 1, laser unit 2, ultrasonic and distance measuring unit 3, fixation nail implantation unit 4, negative pressure air extraction and dust removal unit 5 and air conditioning unit 6, of which:

[0038] The combined action unit 1 is inserted in the incision to form an independent space inside and outside the incision, that is, to form a closed structure in the incision. After the combined action unit 1 is inserted, the end abuts against the bone to be drilled;

[0039] Such as image 3 As shown, the laser unit 2, the ultrasonic and ranging unit 3 and the fixation nail implantation unit 4 are movably connected to the support structure 8 through the switching mechanism 7, so that any one of the three is coaxial with the combined action unit 1; when different When the unit is facing the combined action unit 1 to complete the function of the unit, fo...

Embodiment 2

[0044] Such as figure 1 As shown, the present invention provides a laser device for orthopedic surgery, including: combined action unit 1, laser unit 2, ultrasonic and distance measuring unit 3, fixation nail implantation unit 4, negative pressure air extraction and dust removal unit 5 and air conditioning unit 6, of which:

[0045] The combined action unit 1 is inserted in the incision to form an independent space inside and outside the incision, that is, to form a closed structure in the incision. After the combined action unit 1 is inserted, the end abuts against the bone to be drilled;

[0046] Such as image 3 As shown, the laser unit 2, the ultrasonic and ranging unit 3 and the fixation nail implantation unit 4 are movably connected to the support structure 8 through the switching mechanism 7, so that any one of the three is coaxial with the combined action unit 1; when different When the unit is facing the combined action unit 1 to complete the function of the unit, f...

Embodiment 3

[0076] Such as figure 1 As shown, a method of using laser equipment for orthopedic surgery of the present invention, for femoral neck fractures and trochanteric fractures, it is necessary to drill a circular hole with a diameter of 2.5-10 mm and a depth of 70-110 mm at the fracture site for Insert pins for fixation. The specific implementation method first determines the surgical site and angle according to the medical images of the affected area, and operates the robotic arm to align the combined action unit 1 with the surgical site (parallel to the axis); customize the silicone contact head according to the bone surface topography, and install it on the front end of the combined action unit 1 , make an incision parallel to the operating bed in the affected area, operate the mechanical arm to insert part 1 of the combined action unit into the incision, and stick the contact head to the surface of the bone tissue; set the laser parameters, replace the focusing system component...

Abstract

The invention provides laser equipment for orthopedic surgery and a using method, and relates to the technical field of medical instruments. The technical problems that the laser equipment for orthopedic surgery is tedious in steps, poor in heat dissipation effect, difficult in heat injury inhibition and poor in cleaning effect are solved. The laser equipment for the orthopedic surgery comprises a combined action unit, a laser unit, an ultrasonic and distance measuring unit, a fixing nail implanting unit, a negative pressure air exhaust and dust removal unit, a cold air unit and three sets of telescopic mechanisms. The using method comprises the following steps that the equipment is aligned with a to-be-drilled part; the equipment is basically arranged and fixed; parameters of the laser are set; laser drilling is carried out; ultrasonic and distance measurement and negative pressure cleaning treatment are carried out; and fixing nails are implanted. Air exhaust and dust removal are carried out on the drilling part in a negative pressure suction mode, the purification effect is good, drilling and cooling are carried out simultaneously through the cold air unit and laser, the cooling effect is good, a high-power laser can be used, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a laser device for orthopedic surgery and a method for using it. Background technique [0002] For femoral neck fractures and trochanteric fractures, it is necessary to drill a circular hole with a diameter of 2.5-10 mm and a depth of 70-110 mm at the fracture site to implant fixation screws for fixation. Mechanical drilling is used to drill holes for the fracture site to facilitate fixation of the fracture site. However, during the drilling process, it is necessary to precisely control the direction and depth to avoid damaging important organs and tissues, which requires extremely high operating experience of medical personnel. In order to solve this problem, laser devices for orthopedics have appeared on the existing market. Lasers are used to drill holes. Lasers can replace traditional physical methods for orthopedic surgery, which can solve the problem of low precisi...
