Auxiliary tool for flexible arthroscope

Abstract

The invention discloses an auxiliary tool for a flexible arthroscope. The tool comprises a soft tissue depth measuring ruler and a sleeve for the arthroscope. The soft tissue depth measuring ruler comprises a handle, a ruler body, a measuring head and a holding handle; the top end of the handle is connected with the ruler body, and the length direction of the ruler body is perpendicular to the handle; the measuring head extends forwards from the front end of the ruler body, and the top of the holding handle is arranged in the top end of the handle and extends obliquely and outwards in the length direction of the handle; the top of the holding handle is connected with the measuring head through the ruler body. When the holding handle rotates opposite to the handle with the top of the holding handle as the axis center, the measuring head rotates and is used for measuring the depth of an incision of soft tissue. The sleeve for the arthroscope comprises an inlet end, a sleeve body and an outer end which are connected in sequence, wherein a sealing channel is formed among the inlet end, the sleeve body and the outer end, the inlet end and the outer end extend towards the outside of thesleeve body to form inner and outer low flange structures, and the inlet end and the outer end are arranged in an inner layer and an outer layer of the soft tissue are respectively, and the sleeve body is fixed in the incision of the soft tissue.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to an auxiliary tool for soft arthroscopy. Background technique [0002] Arthroscopy is not only an auxiliary means of joint inspection, but also the main treatment means in the fields of joint surgery and sports medicine. Arthroscopic surgery and arthroscopic-assisted open surgery are not only successfully used in the diagnosis and treatment of most knee joint injuries, but also more and more used in shoulder, elbow, wrist, hip, ankle and other joints. In modern orthopedics, arthroscopic surgery has become an indispensable daily operation. Before the current arthroscopic surgery is carried out, in order to ensure that the arthroscopic and other surgical instruments can be stably and smoothly inserted into the joint, it is necessary to use a silicone sleeve to establish a stable channel for the instrument to be inserted in the soft tissue incision. Currently, there is n...

Problems solved by technology

Before the current arthroscopic surgery is carried out, in order to ensure that the arthroscopic and other surgical instruments can be stably and smoothly inserted into the joint, it is necessary to use a silicone sleeve to establish a stable channel for the instrument to be inserted in the soft tissue incision. Currently, there is no incision. In the case of the sounding device, it is difficult to accurately grasp the depth of the incision so as to select the corresponding size of the silicone sleeve

[0003] During arthroscopic surgery, due to the lack of access protection equipment, it is easy to cause edge soft tissue damage when using surgical instruments, thereby increasing the risk of surgery. At present, threaded sleeves are used in surgical procedures, and threaded sleeves are made of plastic. The material is very hard. When using it, the doctor needs to use the thread on the wall of the cannula to screw the cannula into the soft tissue incision. After the installation is completed, the surgical instruments can stably enter and exit the surgical area through the threaded cannula. However, due to the limitation of its material and structure, When the threaded sleeve is installed, its thread structure often causes soft tissue damage. In addition, due to the poor sealing performance of the threaded sleeve, a large amount of lavage fluid often overflows during the operation, reducing the clarity of the field of view in the operation area.
