Description

A kind of pharyngeal cavity belemnoid amputation knife

Affiliated technical field

This utility model relates to a kind of medical apparatus and instruments of pharyngeal cavity belemnoid amputation knife, is applied to cut off the long belemnoid in the pharyngeal cavity.

Background technology

During elongated styloid process, the patient often has foreign body sensation and uncomfortable pain in the pharyngeal cavity, also can feel the sense that has wound not heal after the operation on tonsils excision, and real be the long event of belemnoid calcification.Belemnoid normally is 25-30mm, and it is long surpassing the person, needs excision.There is not at present special utensil can supply the long pharyngeal cavity belemnoid of excision as yet.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, and a kind of pharyngeal cavity belemnoid amputation knife are provided.

The purpose of this utility model can reach like this, a kind of pharyngeal cavity belemnoid amputation knife, form by cutter hub and the handle that is attached thereto thereof, handle comprises that main handle and secondary handle link together by one, on main handle and secondary handle side separately in opposite directions, fix with an end of an arcuate bombing leaf respectively, another end of one spring leaf is that an aperture is arranged, and another end of another spring leaf has a tenon to insert in this hole, and both fix.Therefore when pinching outside main handle and secondary handle with a hands, sway between two handles, two spring leafs are compressed simultaneously; When loosing one's grip, spring is replied original free state.Secondary handle is crossed the other end of rotating shaft, link to each other with secondary tool arm by one, the other end that main handle is crossed rotating shaft fixes with the operator arm, and the operator arm is positioned at secondary tool arm below, secondary handle penetrates from operator arm downside, reaches the aperture that the upside of operator arm inserts in the secondary tool arm through the square hole in it and is fixed by axle.Secondary tool arm is provided with last stop and middle stop, they respectively with the operator arm on chute be connected with slotted hole, secondary tool arm can only slided before and after arm body direction on the operator arm.Secondary tool arm end is to split the shape blade, is with a tool rest on the operator arm, has on the seat and is compatible with the cutter groove of splitting the shape blade.

It is smooth to the utlity model has otch; Characteristics simple to operation.

The specific embodiment

This utility model is further described below in conjunction with accompanying drawing.A kind of pharyngeal cavity belemnoid amputation knife, form by cutter hub and the handle that is attached thereto thereof, handle comprises main handle (9) and secondary handle (11), and both link together by one (13), on main handle (9) and secondary handle (11) side separately in opposite directions, fix with an end of an arcuate bombing leaf (7) respectively, another end of one spring leaf is that an aperture is arranged, another end of another spring leaf has a tenon to insert in this hole, and both fix.Secondary handle (11) is crossed the other end of rotating shaft (13), link to each other with secondary tool arm (1) by one (5), the other end that main handle (9) is crossed rotating shaft (13) fixes with operator arm (3), operator arm (3) is positioned at secondary tool arm (1) below, secondary handle (11) penetrates from operator arm (3) downside, and the aperture that the upside that reaches operator arm (3) through its interior square hole inserts in the secondary tool arm (1) is fixing by axle (5).Secondary tool arm (1) is provided with last stop (17) and middle stop (15), they respectively with the arm (3) of operating on chute be connected with slotted hole.Secondary tool arm (1) end is to split shape blade (23), is with a tool rest (19) on the operator arm (3), has on the seat (19) and is compatible with the cutter groove (21) of splitting shape blade (23).

During use, clutch main handle (9) and secondary handle (11), two spring leafs this moment (7) are wronged, and two handles rotate around axle (13).At this moment, be subjected to secondary handle (11) to cross the effect of the other end of axle (13), the secondary tool arm (1) that links to each other by axle (5) is because of the restriction of stop (17,15) with it, makes that to split shape blade (23) close to the cutter groove (21) of tool rest (19).When loosing one's grip, two spring leafs (7) are returned to original state, and blade (23) leaves tool rest (19) to original natural place.During clinical this cutter of use, should tie belemnoid earlier with silk thread the silk thread head is pulled out outside the oral cavity, cut off long belemnoid with this utility model then, the end of a thread and cutter are together extracted out, the belemnoid of cutting off promptly is extracted into outside the oral cavity, and cut belemnoid can avoid falling into lower respiratory tract and esophagus.
