Drill sleeve provided with water spray rubber ball

Abstract

The invention discloses a drill sleeve provided with a water spray rubber ball. The drill sleeve provided with the water spray rubber ball comprises a sleeve, a water inlet chamber, the rubber ball and a catheter, wherein the water inlet chamber is fixed in the outer wall of the sleeve, a cavity is formed between the water inlet chamber and the outer wall of the sleeve, and a water inlet pipe is arranged at the upper end of the water inlet chamber; a plurality of water spray holes are formed in the positions, corresponding to the water inlet chamber, in the inner wall of the sleeve and are communicated with the cavity; one end of the catheter is connected onto the rubber ball, the catheter is communicated with the rubber ball, and a funnel-shaped connector is arranged at the other end of the catheter and matched with the water inlet pipe. With adoption of the scheme, water can be sprayed for cooling when the drill sleeve is used in an internal fixation surgery process for a fracture, local cooling for a drill is realized in a bone drilling process, blood supply or periosteum of the local bone is protected conveniently and effectively.

Description

technical field [0001] The invention relates to the field of orthopedic surgical medical instruments, in particular to a drill bit sleeve with a water-spraying ball. Background technique [0002] In the process of internal fixation of fractures, when a drill is used to drill and grind the bone under the protection of the sleeve, the local temperature of the drill and grinding place often rises, causing burns to the surrounding tissue or bone. Burnt smell or smoke occurs, and it is often necessary to remove the sleeve or drill bit and then rinse the drilled area. When repositioning the drilled area, deviations often occur. The above drilled and grinded methods are ineffective and time-consuming. SUMMARY OF THE INVENTION [0003] The main technical problem solved by the present invention is that heat will be generated between the drill bit and the sleeve, and between the drill bit and the bone during the drilling process of the drill bit in the sleeve. During the internal f...

Problems solved by technology

[0002] During the internal fixation of fractures, when the drill bit is used to drill and grind the bone under the protection of the sleeve, the local temperature of the drilling and grinding site often rises, causing burns to the surrounding tissue or bone. When there is burning smell or smoke, it is often necessary to remove the sleeve or drill bit and rinse the drilling and grinding place, and when repositioning the drilling and grinding, there is often deviation. The above drilling and grinding methods are not effective and time-consuming
