Description
Technical field
This utility model relates to a kind of medical apparatus, relates generally to a kind of illumination electric knife.
Background technology
Along with the progress of Wicresoft's Medical Technology, operating otch becomes more and more less.Such as, traditional Open Cholecystectomy operation, incision length is generally at about 20cm., the incision length of present Small incision cholecystectomy only needs 2-3cm.Traditional Radical Thyroidectomy, incision length is at about 10cm, and now, incision length is only 3-4cm.The shortening of incision length, relevant with the appearance of the operating reform of ideas, new electrosurgical unit, the attention of sufferer to postoperative wound cosmetic result.
But Micro-traumatic concept is propagated its belief on a large scale in clinical position, the minimal incision * brought also has caused some problems.Such as, have bibliographical information, the incidence rate of the hemorrhage complication after Small incision cholecystectomy is higher than traditional operation.The raising of complication rate, to add operating difficulty relevant with minimal incision *.Wherein, minimal incision * hampers the illumination of light is principal element.The otch of 2cm, the head of operating doctor can cause serious interference to the shadowless lamp of indoor suspended ceiling formula of performing the operation at present.At present, solution adopted clinically two kinds nothing but: 1. increase extra lighting source, its light path avoids the head (namely avoiding doctor's eyes towards the direction in otch) of operating doctor.2. operating doctor increases portable head lamp, and head lamp is enclosed within doctor's head, and adjusting head light road and doctor's eyes are towards consistent.But these two kinds of modes have its defect.Although the first solution ensures that light source enters in otch, because light path can not with doctor's eyes towards being consistent, doctor wants the local light luminance of observation still not enough.During first scheme, although light can with doctor's eyes towards being consistent, along with the change of excision position in art, usually need nurse under platform repeatedly to regulate the position of head lamp.Very loaded down with trivial details, and affect the operation of doctor, add the danger of Infection in operation.
In addition, along with reducing of operative incision, and operation technique is more and more meticulousr, and doctor also has higher requirement to the funtion part of cutting bleeding apparatus in art.Such as, when Radical Thyroidectomy, percutaneous incision undertissue, during free skin flap, requires that the funtion part (i.e. electric knife head) of electric knife wants large with the contact area of tissue, thus incised tissue fast, effectively stop blooding.When excising the lymphoid tissue around recurrent laryngeal nerve, require that the contact area of the funtion part of electric knife and tissue is little, thus the position of cutting can accurately be controlled, the important feature such as the neural blood vessel closed on are protected, avoid accidentally injuring.At present, in clinical position, the solution that doctor adopts is when needs fine dissection, and artificial overlaps a plastic tube or wrap up with plastic sheeting on electric knife head, thus reaches the function regulating electric knife head funtion part and contact tissue area.This scheme has following problem: the plastic tube that (1) electric knife head adheres to or plastic foil small, may be lost in otch in art, therefore, in order to avoid there is this malpractice, in operation, doctor and nurse need ceaselessly to check, and consume a large amount of energy.(2) electric knife is the effect being played cutting and hemostasis by high temperature.Plastic tube conventional at present and plastic foil can not tolerate the high temperature of more than 100 degree, and along with the carrying out of operation, the normal phenomenon occurring fusing, creates noxious substance on the one hand, and the electric knife head at fusing position exposes again in the tissue on the one hand, can cause unexpected damage.
Therefore, seeking can to local adequate illumination in otch in a kind of reliably easy operation, and the apparatus that simultaneously can adjust the contact area of electric knife functional part is desired by those skilled in the art.
Summary of the invention
The purpose of this utility model is, to provide in a kind of art and to local lighting in otch and can the apparatus of area at regulatory function position, can reach local lighting in small incision surgery, the object of fine dissection.
In order to realize above-mentioned task, this utility model takes following technical solution:
A kind of illumination electric knife, this electric knife comprises electric knife body and electric knife head, also comprises illuminace component, and described illuminace component movable is set on electric knife body, and illuminace component can carry out the movement of circumference and axis relative to electric knife head.
Concrete, described illuminace component is ring bodies, and this ring bodies is set on electric knife body, mounted LED lamp on illuminace component.
Further, illuminace component arranges holding device, described holding device comprises fastening nut and holddown groove, and holddown groove is arranged along the length direction of electric knife body.
Further, described electric knife also comprises protective sleeve, the movable internal layer being arranged on electric knife body of this protective sleeve, is controlled the exposed length of electric knife head by the extension elongation of protective sleeve.
Concrete, described protective sleeve is tubular insulation body.
More specifically, described protective sleeve controls extension elongation by chute and slide block, and described chute is arranged along the length direction of electric knife body, and slide block is fixedly connected with protective sleeve, by the extension elongation of the Sliding Control protective sleeve of slide block on chute through chute.
Advantage of the present utility model is:
(1) electric knife of the present utility model carries out the illumination in Minimally Invasive Surgery by illuminace component sheathed on electric knife shell, and light path and electric knife head are consistent, and ensures that operative doctor needs to cut or the solidifying position light intensity closed;
(2) illuminace component of the present utility model can carry out the telemechanical of circumferential and axial on electric knife shell, in being performed the operation from the size of electric knife head distance and the position of rotation by illuminace component, different lighting demand is satisfied, the convenient illumination to Wicresoft's wound;
(3) in addition, outside electric knife head, be designed with slideable protective sleeve, when doctor needs the contact area regulating electric knife head and tissue, promote the length that slide block regulates electric knife head to expose voluntarily.
