Orthopedic direction-variable soft and hard integrated endoscope and single approach control method

Abstract

The invention provides an orthopedic direction-variable soft and hard integrated endoscope and a single approach control method. The endoscope is composed of an insertion part and an operation holding part, wherein the insertion part is in a thin and long tube shape, and the operation holding part is connected with an upper end base of the insertion part. The insertion part comprises a hard endoscopic sheath and a direction-variable flexible body which is placed in the hard endoscopic sheath, and one of the hard endoscopic sheath and the direction-variable flexible body is composed of multiple sections of continuous pipe fittings which are telescoping relatively; a soft lens image collection channel, a coaxial instrument operation channel and a water injection irrigation and attracting channel are formed in the direction-variable flexible body, at least two guide inhaul cables are connected to the side wall of the direction-variable flexible body, and the guide inhaul cables are connected to a guide disk arranged in the operation holding part; the operation holding part is provided with an image collector, the interior of the image collector is communicated with the soft lens image collection channel, a host is connected with the outside of the image collector, and the image collector is capable of displaying a three-dimensional image on a monitor. The orthopedic direction-variable soft and hard integrated endoscope has the advantages of being reasonable and compact in structure, convenient to operation, capable of skirting a shelter of the human tissue in a target operation field, capable of making observation free of blind areas and the iatrogenic injury small through complex anatomic spaces, good in observation effect and the like.

Description

technical field [0001] The present invention relates to an orthopedic steerable flexible and rigid endoscope and a single-access control method, which are used for minimally invasive surgery for orthopedic diseases in related fields such as orthopedic joint surgery, spinal surgery, trauma surgery, sports medicine, etc. , including operations on bone joints, long bones of limbs, spine, blood vessels, nerves, tendons, etc., belonging to the technical field of medical devices. Background technique [0002] Endoscope is the basic tool for minimally invasive treatment of orthopedic diseases at present. It can directly observe the condition of the lesion, understand the lesion in a dynamic situation, carry out purposeful and targeted inspection and treatment, and protect the normal anatomical structure from damage to the greatest extent. , has the advantages of minimally invasive surgery, precise treatment, and fast functional recovery. [0003] At present, orthopedic endoscopes ...

AI Technical Summary

Problems solved by technology

[0003] At present, orthopedic endoscopes such as bone joint and spinal endoscopes use rigid unidirectional endoscopes. Due to the fixed field of view of the endoscope, it is impossible to pass through complex anatomical gaps. Rigid passage will cause iatrogenic damage to normal structures in the joints and equipment. It is broken, so there is a blind spot for surgical observation. When other tissues block the target surgical field of view, the anatomical structure behind it is difficult to reveal. It is necessary to increase the approach or remove the normal anatomical structure to reveal. The operation is complicated and prone to blood vessels, nerves, and tendons iatrogenic damage to tissue structures such as bone, cartilage, and intervertebral disc
