An auxiliary tool for soft arthroscopy

Abstract

The invention discloses an auxiliary tool for soft arthroscopy, which comprises a soft tissue sounding ruler and an arthroscope sleeve; the soft tissue sounding ruler comprises: a handle, a ruler body, a measuring head and a grip; the top end of the handle and the ruler body Connection, the length direction of the ruler body is perpendicular to the handle, the measuring head extends forward from the front end of the ruler body, the top of the grip is placed in the top of the handle, and extends obliquely outward along the length direction of the handle, the top of the grip and The measuring head is connected through the ruler body; when the handle rotates toward the handle with its top as the axis, the measuring head rotates to measure the depth of soft tissue incision. The sleeve for arthroscopy includes an access end, a tube body and an outer end connected in sequence; a sealed passage is provided through the access end, the tube body, and the outer end, and both the access end and the outer end extend to the outside of the tube body , forming a low-flange flange structure on both sides of the inner and outer sides, and the entry end and the outer end are respectively placed into the inner and outer layers of the soft tissue to fix the tube body in the soft tissue incision.

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.
