Demountable clamp for sucking polypi

Abstract

The invention relates to a detachable attraction polypus forceps, which is mainly appropriate to the resection operation of polyp of sinus of a human body. A hand handle part of the forceps is respectively connected with an attraction tool bit part and a scabbard part. The attraction tool bit part also comprises an inner pipe and an attraction adapter. The inner pipe is respectively welded with inner tool bit and the attraction adapter. The scabbard part also comprises an outer pipe and an outer pipe adapter sleeve with a through hole. The outer pipe is respectively welded with an outer tool bit and the outer pipe adapter sleeve. The upper end of the front hand handle of the hand handle part is provided with a pin slot and the back hand handle is provided with a spring slot. A main part with the through hole and a slide rod are provided. The main part is welded with the back hand handle. The slide rod is arranged in the inner hole of the main part. The slide rod is also provided with a slide rod pin which is matched with the pin slot of the front hand handle. The spring slot of the back hand handle is internally provided with a spring. And the upper part of the spring is provided with beads. The forceps has reasonable structural design, linearly incises and is controllable and causes small trauma when in operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a detachable polyp-absorbing forceps, which is mainly suitable for sinus polypectomy in human body, especially for sinus endoscopic minimally invasive surgery and postoperative dressing change. Background technique [0002] In the prior art, there are mainly two structures for attracting polyp forceps for sinus surgery. One is based on ordinary medical forceps and is slightly improved according to specific needs. ", as well as the Chinese utility model patent with the patent number 2005201356560 and the name "nasal polyp forceps", all belong to this type of structure; and the trauma of sinus suction forceps with this type of structure is large, so it is not suitable for Endoscopic sinus surgery is minimally invasive, and it can only be applied to open sinus surgery. The other is the electric planer class, such as the Chinese utility model patent whose patent number is 032308752 and the title ...

Problems solved by technology

The other is the electric planer class, such as the Chinese utility model patent whose patent number is 032308752 and the title is "straight-through medical electric planer mobile phone", but the electric sinus planer of this type of structure is due to its rotation during use. Cutting, so it is uncontrollable during the operation, that is, the moment of each cutting is only 0.0075-0.002 seconds, the wrong operation is irreversible, and it is easy to cause damage to the sinus tissue; at the same time, because the cutting direction of the planer is perpendicular to the skull base, orbital cardboard, and optic nerve , increased surgical risk
