Abstract

The utility model discloses maxillary sinus tissue forceps for solving the problems of large side injury and large operation risk in the prior art. The maxillary sinus tissue forceps comprise forceps handles, a forceps body and a jaw, wherein the forceps handles comprise a movable handle and a fixed handle; a threaded pipe is connected with the forceps body and the jaw; a forceps wire is arranged in the centers of the forceps body and the threaded pipe; the fixed handle is provided with a gear control mechanism; and the gear control mechanism is connected with the jaw through the forceps wire. The forceps can reach each wall of maxillary sinus in multiple angles and multiple azimuths, the threaded pipe section of the forceps body can be bent, and the focus of the maxillary sinus can be flexibly cleared. Meanwhile, the forceps avoid the phenomena that the uncinate process, the natural port of the maxillary sinus and the rear end of the inferior nasal concha must be treated for exposing the pathological tissues in the conventional surgery and the new surgical maxillary sinus and inferior meatus windowing operation inevitably expands the surgery range and increases unnecessary wound. Through the multifunctional maxillary sinus tissue forceps, the visible and inaccessible pathological tissues such as maxillary sinus cysts, polyp and the like can be viewed.

Description

The maxillary sinus tissue forceps

Technical field

This utility model belongs to medical instruments field, particularly a kind of apparatus that is used for maxillary antrum operation.

Background technology

The maxillary sinus pathological changes is common clinical, frequently-occurring disease, often causes patient's headache, giddy, diseases such as nasal obstruction when pathological changes is delayed nasal cavity, usually occur; Belong to the conchoscope routine operation, but because lesions position is hidden, operation technique is difficulty often; In order thoroughly to remove focus, often to enlarge range of operation at all costs clinically, with moving outside the fracture of concha nasalis inferior rear end; The excision unciform process enlarges maxillary sinus nature mouthful anteroposterior diameter.The pair damage that this had both enlarged operation has prolonged operating time again, has increased operation risk simultaneously.

There is the scholar to window at present and removes the maxillary sinus pathological changes,, increased an operation that inferior nasal meatus is windowed, enlarged the operation wound scope the patient is extra though can achieve the goal through inferior nasal meatus.

The utility model content

The purpose of this utility model provides a kind of maxillary sinus tissue forceps, and is big to solve the pair damage that exists in the prior art, the big problem of operation risk.

This utility model adopts following technical scheme:

A kind of maxillary sinus tissue forceps; Comprise pincers handle, caliper, jaw; Said pincers handle comprises movable handle and fixed handle, is connected with corrugated tubing between said caliper and the jaw, and the center of said caliper and corrugated tubing is provided with the pincers silk; Said fixed handle is provided with position control mechanism, and position control mechanism links to each other with jaw through the pincers silk.

This utility model ability multi-angle, multi-faceted each wall of arrival maxillary sinus, vice body screw thread pipeline section can be bent, and can remove the maxillary sinus focus flexibly.Avoided simultaneously previously performing the operation in order to expose pathological tissues, must handle unciform process, maxillary sinus nature mouth and concha nasalis inferior rear end, new art formula maxillary sinus inferior nasal meatus windowing has also inevitably enlarged range of operation, has increased unnecessary wound.The invention of this Multifunction maxillary sinus tissue forceps makes pathological tissues such as visible out of reach maxillary cyst, polyp show the optical fundus completely, and it is handy to operate.

Fig. 2 is the structural representation of fixed handle of an embodiment of this utility model;

Fig. 3 is the working example figure of an embodiment of this utility model.

The specific embodiment

As shown in the figure; This utility model maxillary sinus tissue forceps comprises pincers handle 1, caliper 2, jaw 3, and said pincers handle 1 comprises movable handle 101 and fixed handle 102; Be connected with corrugated tubing 8 between said caliper 2 and the jaw 3; The center of said caliper 2 and corrugated tubing 8 is provided with pincers silk 11, and said fixed handle 102 is provided with position control mechanism 5, and position control mechanism 5 links to each other with jaw 3 through pincers silk 11.Said fixed handle 102 is provided with scale 6.Because of position control mechanism 5 is one through the pincers silk in the caliper 2 11 with jaw 3, position control mechanism 5 slides along fixed handle 102 front and back and regulates scale 6, reaches the effect of regulating pincers silk 11 length, also just plays the effect of quantitatively accurately regulating caliper 2 active lengths.

Between said pincers handle 1 and caliper 2, be provided with jaw direction-changing device 4,360 ° of rotations vertically.Corrugated tubing 8 is convenient to regulate caliper 2 distal directions according to the maxillary sinus diseased region in the operator art.

Be provided with attraction passage 7 in the end of said pincers handle 1.Can in time remove blood, keep the art open country clear.

Fig. 3 is the working example figure of an embodiment of this utility model, under the conchoscope direct-view is guided, carries out during this utility model instrumentation, earlier with movable handle 101 of caliper and fixed handle 102 closures; Reach middle nasal meatus 9 along the meatus nasi communis entering, find maxillary sinus nature mouth 10, jaw 3 is from mouthful 10 entering of maxillary sinus nature; The observation lesion locations of can going directly, divide two kinds of situation: a kind of direct when can pincers getting focus, retract movable handle 101; Peep under the direct-view at intranasal, thoroughly remove pathological tissues; Still can't visit pathological tissues when another kind of caliper opens, this moment, the advantage of multifunctional pincer can manifest.

At first regulate the direction of caliper 2 corrugated tubings 8, make the caliper far-end aim at the pathological changes direction.Scale through regulation stall controlling organization 5 is accurately adjusted the caliper active length then, makes jaw 3 any maxillary sinus diseased region that can go directly flexibly.Further regulate jaw 3 directions through adjustment jaw direction-changing device 4; Be convenient to clamp smoothly get pathological tissues, accurate design ergonomic can thoroughly easily be removed the maxillary sinus pathological tissues; The caliper design meets minimally invasive surgery, reaches very fine surgical effect.

Above-described only is the preferred embodiment of this utility model; The technical scheme of this utility model is not so limited; Should be understood that to those skilled in the art; Under the teachings that this utility model provided, can also make other equivalent modifications and improvement, also should be regarded as the scope of this utility model claim protection.
