Abstract

The invention discloses a kind of curets, it mainly include bar portion, handle, handle is made of handle pull end and handle rear lug, and handle is fixedly connected by the way that the shank transition position on handle pull end top is arranged in bar portion, and bar portion is bent upwards and is fixed with curet cutter head at apical position.Wheat forming head portion of the invention easily can reach sinus frontalis through meatus conchae ethmoturbinalis minoris nature channel in conjunction with ridge-shaped back.The cutting edge gradient of 45° angle effectively increases cutting edge strength.0.6mm is reduced at the interior year-on-year cutting edge of bowl to be ensured to cut out except object cannot be embedded in the rim of a bowl, realizes that nature falls off.It is more suitable for the natural grip position of people on the whole, is significantly improved to the stability and comfort of surgical procedure.As so accurately surgical instrument China Grade A hospital relies on imported product to specific aim for a long time, country can be not only responded after implementation success call and realize domestic substitution import, moreover it is possible to save a large amount of purchase costs for country.

Description

A kind of curet

Technical field

The present invention relates to the fields of medical instrument, and in particular to ear-nose-throat department, which is cuted out, to be used except bone tissue and surface mucosa A kind of curet.

Background technique

Curet is cuted out when being ent surgery except the common a kind of medical instrument of bone tissue and surface mucosa.

Existing curet structure key bit is in oval or oval mostly, and the rim of a bowl position is in pot bottom-shape, and back position is in circular arc Shape, and it is excessive using taper in shank junction.Such structure have the following deficiencies: oval or oval capitiform and it is arc-shaped after Back will affect cut out except when turn the room for maneuver；Pot bottom-shape the rim of a bowl is easy insertion and cuts out except object can also accelerate the rate of wear of cutting edge, Removing solid capacity is cuted out to reduce curet；It excessively will lead in shank junction using taper and shakiness integrally held to curet, it can not Meet complicated operation requirement, need multiple valve replacement instrument, to removal pathological tissues and realizing continuously cut out except be all it is unfavorable, And then influence surgical quality and procedure efficiency.It is therefore desirable to develop a kind of curet to cut out preferably to solve ear-nose-throat department except bone The problem of tissue and surface mucosa.

Summary of the invention

It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of curet.

The object of the present invention is achieved by the following technical solutions: this curet, mainly includes bar portion, handle, hand Handle is made of handle pull end and handle rear lug, and handle passes through the shank transition position that handle pull end top is arranged in and the fixed company of bar portion It connects, bar portion is bent upwards and is fixed with curet cutter head at apical position.

The upper and lower surface of the handle pull end is provided with non-slip groove, and non-slip groove 3 is using concave-convex helicitic texture.

The curet cutter head uses bowl shaped structure, is made of cutting edge and the rim of a bowl, and the year-on-year Blade dimensions of the rim of a bowl size reduce 0.6mm, it is ensured that cut out and fall off naturally except object from cutting edge.

The invention has the benefit that being more suitable for the natural grip position of people, the stability operated when to operation has with comfort It significantly improves；Reach light, quickly cut out except effect, it is stability when the design that shank excessively place reaches improves operation, comfortable Accuracy that property and operator are affectedly bashful, degree of holding with a firm grip；Country can be responded simultaneously and calls the domestic substitution import of realization, saved for country big Measure purchase cost.

Specific embodiment

Below in conjunction with attached drawing, the present invention will be described in detail:

Embodiment: as shown in the picture, this curet includes mainly bar portion 5, handle 7, and handle 7 is by handle pull end 2 and handle Rear lug 1 is constituted, and handle 7 is fixedly connected by the way that the shank transition position 4 on 2 top of handle pull end is arranged in bar portion 5, and bar portion 5 is upward It is bent and is fixed with curet cutter head 6 at apical position.

The upper and lower surface of the handle pull end 2 is provided with non-slip groove 3, and non-slip groove 3 is using concave-convex helicitic texture.

The curet cutter head 6 uses bowl shaped structure, is made of cutting edge 8 and the rim of a bowl 9, and year-on-year 8 size of cutting edge of 9 size of the rim of a bowl Reduce 0.6mm, it is ensured that cut out and fall off naturally except object from cutting edge 8, cannot be embedded in the rim of a bowl 9.

The non-slip groove interval A is 5.5mm, and anti-skidding groove radius B is 4.5mm, and handle front end thickness C is 5.2mm；Shank transition position 4 recess radius D is 4mm, and convex radius E is 12mm, and gauge diameter F is 4.6mm, and transition position length G is 8.5mm；Curet knife Long H is 5.5mm in first 6 bowl, and cutting edge foreign minister I is 6.1mm, and bowl inner width J is 1.7mm, and cutting edge outer width K is 2.3mm, cutting edge height L is 0.3mm, and cutting edge gradient M is 45 °, and bowl depth N is 0.8mm.

Wheat forming head portion in present invention design can easily be arrived through meatus conchae ethmoturbinalis minoris nature channel in conjunction with ridge-shaped back Up to sinus frontalis.The cutting edge gradient of 45° angle increases the intensity of cutting edge.0.6mm is reduced at the interior year-on-year cutting edge of bowl to be ensured to cut out except object cannot It is embedded in the rim of a bowl, realizes that nature falls off.Ridge-shaped back ensures cutting out except room for maneuver when turning between back and tissue more Greatly.Sharp cutting edge, the bowl-type less than cutting edge, the triplicity of ridge-shaped back are, it can be achieved that continuously cut out the optimum efficiency removed.It holds When, middle finger is put in recess, and index finger is put in the right side of shank, and thumb is pressed at the non-slip groove above handle, is more suitable for oneself of people Right grip position, the stability when structure is to surgical procedure are significantly improved with comfort.As specific aim so accurately surgical device Tool China Grade A hospital relies on imported product for a long time, and country can be not only responded after implementation success and calls the domestic substitution of realization Import, moreover it is possible to save a large amount of purchase costs for country.

It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
