Embodiment Construction

[0017] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] The curette is composed of a whole connected by a spoon shaft 3 with a spoon head 1 and a spoon handle 4 .

[0019] The junction of the key head 1 and the key shaft 3 is an eccentric and open semicircle, such as figure 2 shown.

[0020] An optical fiber bundle 10 , a video signal line 9 , an electronic circuit board connected with an image sensor, and a camera 15 form a camera assembly 2 .

[0021] In order to ensure that the curette can work in the cavity of a smaller wound, the diameter of the protective tube 8 is very small, usually 1-5 mm, and the inner diameter of the channel 5 at the front end of the key shaft is 1.5-6 mm. The camera assembly 2 at the opening of the front end of the protective tube has a diameter of 1 to 5 mm and is closely matched with the protective tube. At the same time, the slender camera assembly is locate...

Abstract

The invention discloses an orthopedics curette for use in minimally invasive surgery. The orthopedics curette comprises a curette and protective tube provided with a clamping block which are connected into a whole, wherein the protective tube is connected in a channel of a curette rod, a curette handle and the clamping block; a video transmission device is arranged in the protective tube, and is an image pickup assembly consisting of a light guide fiber bundle, an electronic circuit board which is connected with an image sensor, a video signal line and a camera; the image pickup assembly is connected with the video signal line, the light guide fiber bundle and a light source; and the camera is arranged close to the curette rod. The functions of the curette and a sight are combined, observation, surgery and treatment are integrated, a reliable surgical appliance is provided for the application of orthopedics minimally invasive surgery, and only a small incision is required to be formed on a focus; and the curette is inserted into a wound, and surgical operation is performed directly under a display screen of a display, so that the real status of pathological changes of tissues inside bone vertebra and the entrance depth of a curette head can be observed more clearly, the accuracy of examination and surgical operation is increased, damages caused by blind reduction of normal tissues are reduced, and pain, burdens and medical risks of patients are reduced.

Description

technical field [0001] The invention relates to a medical instrument, in particular to an orthopedic curette for minimally invasive surgery, which can be used as an orthopedic surgery to observe bones and vertebrae, etc., and to perform direct-viewing operations through a display screen. Background technique [0002] With the vigorous development of science and technology, the endoscope is a product of modern high technology. It can penetrate into places invisible to the naked eye and see clearly the internal conditions of human organs. It has been widely used in the fields of industry, science and technology, and medical diagnosis and treatment. application, and patents for applying endoscope technology to minimally invasive surgery also came into being. [0003] In orthopedic surgery, especially the diagnosis and treatment of the spine, because it is difficult to directly observe the bone and spine, endoscopy and curette surgery are usually performed in two separate states...
