Sleeve tube for arthroscope

Abstract

The invention discloses a sleeve tube for an arthroscope. The sleeve tube is used for the approaching protection of the arthroscope. The sleeve tube comprises an approaching end, a tube body and an outer end which are sequentially connected, a sealing passage is formed in the part between the tube body and the outer end, the approaching end and the outer end both extend towards the outer side of the tube body to form a flange structure with low flanges on both inner and outer sides, the approaching end and the outer end are embedded in both inner and outer layers of soft tissues respectively to fix the tube body in a soft tissue incision, and therefore a safe and stable entrance and exit for subsequent surgical instruments.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to an arthroscope sleeve. Background technique [0002] 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, The thread structure of the threaded sleeve often causes soft tissue damage when the threaded sleeve is installed. In addition, due to the poor sealing performance...

[0002] 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 vision in the operation area.
