Problems solved by technology

However, during the operation, due to the removal of the cornea, the original pressure balance is broken, and the contents of the eyeball may be squeezed out. In severe cases, the operation will fail. Therefore, it is necessary to release the pressure in the eyeball to Ensuring that the tissues within the eyeball remain in place as much as possible

Abstract

The invention discloses a pressure regulating device for the posterior segment of the eye during penetrating keratoplasty, comprising a negative pressure machine, a liquid suction needle and a connecting pipe. The negative pressure machine is provided with a first pipe joint, and the tail of the liquid suction needle is provided with a second pipe joint. Two pipe joints, one end of the connecting pipe is connected with the first pipe joint, the other end is connected with the second pipe joint, and a pressure adjustment knob is arranged on the negative pressure machine. Compared with the prior art, the technical solution of the present invention can precisely control the pressure in the eyeball during the penetrating corneal transplantation operation, and avoid the extrusion of the contents of the eyeball. Penetrating keratoplasty is safe, reduces the difficulty of surgery, and avoids serious complications such as prolapse of eye contents.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pressure regulating device for the posterior segment of the eye in penetrating keratoplasty. Background technique [0002] Penetrating keratoplasty is to remove all the cornea of ​​the patient during the operation and replace it with a healthy cornea. It is suitable for diseases such as severe full-thickness corneal opacity or full-thickness corneal thinning. There may be a certain rejection after surgery, and it needs to be treated at a later stage. Anti-rejection drugs are used for a long time to ensure the safety of the cornea. Normally, the cornea coats the outer surface of the eyeball and maintains the balance of pressure inside and outside the eyeball. However, during the operation, due to the removal of the cornea, the original pressure balance is broken, and the contents of the eyeball are squeezed out. In severe cases, the operation will fail. Make sure that the ti...
