Frontal sinus opening punch forceps

Abstract

The invention relates to a frontal sinus opening punch forceps, and relates to a nasal endoscope minimally invasive surgical instrument, which mainly solves the problem that the known clinical surgical forceps are straight forceps heads with upper and lower opening and closing, and are inconvenient, inaccurate, incomplete or accidental in resection of tissue structures such as uncinate process heads and frontal recess cells that grow vertically up and down in the sagittal position in the frontal sinus opening area. According to the invention, two jaws are engaged with each other and horizontally opened and closed on side to side. The two jaws are tilted upward 45 degrees with a forceps rod. The frontal sinus opening punch forceps of the invention can conveniently and accurately remove theuncinate process heads in the frontal sinus opening area and the adjacent ethmoidal slices and soft tissues. The lower part of the head end of the forceps rod is provided with a suction tube, which isconvenient to draw blood stains to ensure cleanness of the surgery field. By the use of the frontal sinus opening punch forceps, the operation is convenient and accurate, the minimally invasive operation is ensured, the surgical effect is improved, and complications are avoided.

Description

technical field [0001] The invention relates to a nasal endoscopic minimally invasive surgical instrument, in particular to a forceps with suction, upturned and upturned 45° frontal sinus opening and cutting forceps. Background technique [0002] The opening of the frontal sinus is the only ventilation and drainage channel of the frontal sinus; resection of the head of the uncinate process and its adjacent sieve chambers (nasal mound air cells, upper bubble air cells) in the area of ​​the frontal sinus opening is necessary for the opening of the frontal sinus by endoscopic surgery Steps: The anatomical structure of this area is complex and concealed, adjacent to the important structures of the orbit and anterior skull base, when resecting the head of the uncinate process and its adjacent bone of the ethmoid chamber, the orbit and the anterior skull base will be damaged by a little carelessness, resulting in vision loss, Severe complications such as strabismus and cerebrospin...

AI Technical Summary

Problems solved by technology

[0005] The pliers head of the present invention is upturned by 45° and can reach the hidden area above the opening of the frontal sinus, which overcomes the shortcoming of ordinary straight pliers heads; the pliers head has a ring-shaped occlusal cutting relationship, and the pliers head can be opened and closed horizontally on the left and right, which can facilitate clamping The head of the uncinate process in the sagittal vertical shape of the opening area of ​​the frontal sinus and its adjacent ethmoid bone slices can be maintained and accurately removed, which overcomes the disadvantage that ordinary straight forceps can only be clamped but cannot be accurately removed; the lower part of the head of the forceps has a The suction tube can suck blood from the surgical field, ensure the surgical field is clean, and facilitate the observation of anatomical structures. The field is clean, and it can conveniently and accurately remove the head of the uncinate process and its adjacent ethmoid bone fragments and soft tissues in the hidden area above the opening of the frontal sinus, making the operation convenient and accurate, ensuring minimally invasive surgery, and improving the curative effect of the operation , to avoid complications
