Embodiment Construction

[0023] The present invention will be further technically described below with reference to the accompanying drawings and examples.

[0024] Such as Figure 1-8 As shown, a minimally invasive absorbable screw guide device includes a double-hole guide 1 , a guide pin guide 2 and a guide pin depth gauge 3 .

[0025] Described double-hole guide 1 comprises a first guide tube 101 and a second guide tube 102, and the first guide tube 101 and the second guide tube 102 are arranged in parallel up and down, and the first guide tube 101 is positioned above the second guide tube 102; The head end of the first guide tube 101 is inclined, and the head end of the second guide tube 102 is serrated. In this application, the side-by-side double-hole sleeve structure ensures the stability and convenience of the arthroscopic operation. The inner diameter of the first guide tube 101 of the present application is smaller than the inner diameter of the second guide tube 102, and the first guide tu...

Abstract

The invention discloses a minimally invasive absorbable screw guiding device. The minimally invasive absorbable screw guiding device comprises a double-hole guider, a guide needle guider and a guide needle depth finder, wherein the double-hole guider comprises a first guide tube and a second guide tube; the tail ends of the first guide tube and the second guide tube are connected with a handle; a positioning slot is inwards formed in one side, which is away from the guide tubes, of the handle; the guide needle guider comprises a guide needle sleeve; the tail end of the guide needle sleeve is connected with a positioning block; the guide needle sleeve is in inner hole clearance fit with the second guide tube; the positioning block is embedded in the positioning slot; the guide needle depth finder comprises a base body; the head end of the base body is attached to one side, which is away from the guide needle sleeve, of the positioning block; a guide needle groove is formed in the central axis of the base body; and a graduated scale is arranged on the rear part of the base body along the extending direction of the guide needle groove. By the guiding device, directional drilling and fixing of a fracture block in a minimally invasive surgery can be realized, the operation difficulty of the surgery is reduced, the surgery speed is increased, the stability is improved, and therefore, the quality of the surgery is guaranteed.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a minimally invasive absorbable screw guiding device. Background technique [0002] During orthopedic implant surgery, usually after positioning to the corresponding position of the bone, a drilling device is used to drill holes to form a channel. In order to improve the accuracy of the drilling channel and the stability during the drilling process, a sleeve is chosen to guide the drilling part of the drilling device. During the existing fracture operation, the orthopedic drilling guide technology has the following problems: when the patient's bone is drilled through the guide device, the fracture block is easy to shift, and the drilling direction is easy to deviate. The operation time cannot meet the operation requirements of efficient and fast operation, and increases the difficulty of operation, which affects the overall therapeutic effect.
