Embodiment 2

[0060] Embodiment 2, specifically, an annular slider 15 is fixed on the cylinder 1, and an annular slide rail 15 is provided on the inner wall of the sleeve 4, and the slider 15 can rotate in the slide rail 14. , to ensure that the cylinder-1 rotates normally to drive the helical rotor 2 to rotate, while the sleeve-4 does not rotate.

Embodiment 3

[0061] Embodiment three, concretely, the rotation of drill piece 7 needs to have rotating part, and this rotation part is installed with the support 16 that matches with the number of drill piece 7 on the outer wall of sleeve one 4, promptly has 4 altogether, and support 16 is Angled inclination is arranged, and rotating shaft one 17 is installed on the termination of support 16, is fixed with drill piece 7 on rotating shaft one 17, and rotating shaft one 17 coaxially is connected with pulley 9, is provided with coil spring 18 on rotating shaft one 17.

[0062] During use, when the drill piece 7 is placed on the outside of the screw head 2, and when it is in a static state, there is an interval 8 between every two drill pieces 7, and the tip of the drill piece 7 is in a circular hollow shape , the circle is relatively small and does not affect the use of drilling, and the coil spring 18 at this time makes the drill piece 7 have a pressing force biased towards the direction of t...

Embodiment 4

[0063] Embodiment 4, specifically, the length of the drill piece 7 is greater than the length of the helical rotor 2, so that the drill piece 7 can wrap the helical rotor 2 (not completely sealed and wrapped), and the end of the upper end of the second sleeve 5 The distance from the end to the end of the sleeve-4 upper end is greater than the length of the drill piece 7.

[0064] In this way, the helical rotary head 2 is placed in the drill bit 6, and when the drill piece 7 is pulled, the drill piece 7 starts to turn over, and the turned-over drill piece 7 has not yet touched the sleeve two 5, so that the subsequent drill piece 7 enters the The inner wall of sleeve two 5 is prepared.

Abstract

The invention relates to an arthroscope threading device for an orthopedics department, and effectively solves the technical problems that in an existing arthroscope operation, many operation tools are used, threading and sewing are easy to fall off, and the operation tools are inconvenient to use. The device comprises a column body I; a spiral swivel, which is arranged at one end part of the column body I, wherein spiral threads are arranged on two sides of the spiral swivel; a sleeve I, wherein the column body I is rotationally arranged in the sleeve I; a sleeve II, which is arranged outsidethe sleeve I in a sleeving manner; a drill bit, which is composed of a plurality of drill pieces, and has an annular section; and a pulling device. The pulling device comprises a pulley. Two oppositeT-shaped slots are formed in the end part of the outer side of the sleeve I; a pull ring arranged at the outer end of the sleeve II is arranged on the outer side of the sleeve I in a sleeving mode, sliding blocks arranged in the T-shaped slots are fixed to the inner side of the pull ring, a pull rope is wound around the pulley, and the other end of the pull rope penetrates through the side wall of the sleeve II and is connected to the pull ring. The device can be produced, creates a positive effect, and is practical.

Description

technical field [0001] The invention relates to the technical field of orthopedic surgery, in particular to an arthroscopic wire-passing device for orthopedics. Background technique [0002] Arthroscopy is a rod-shaped optical instrument with a diameter of about 5mm for observing the internal structure of joints. It is an endoscope used for diagnosis and treatment of joint diseases. An arthroscope has a lens attached to the end of a thin tube that is inserted into the joint and the structures inside the joint are displayed on a monitor. Therefore, the internal structure of the joint can be directly observed. Arthroscopy is not only used for the diagnosis of diseases, but also has been widely used in the treatment of joint diseases. [0003] Arthroscopy is used in many orthopedic operations. For example, arthroscopy is used in the labral repair surgery of the patient's rotator cuff. In this labral repair operation, the main repair principle is to use surgical rope to connec...
