Description

Thread type double-pole electrocoagulator

Technical field

This utility model relates to a kind of medical apparatus and instruments that is used for the intranasal videoendoscopic surgery, relates in particular to a kind of thread type double-pole electrocoagulator.

Background technology

Through nasal endoscopic surgery is the milestone of nose section operation, through nearly 70 years development, the operative indication of intranasal videoendoscopic surgery constantly enlarges, the operation forbidden zone is constantly broken, processing for tumor in the sinunasal and basis cranii pathological changes, the conchoscope technology has begun to demonstrate its advantage, this also has higher requirement to other operating theater instruments simultaneously, wherein stinging pincers with operation develops the most perfect, different shape sting the needs that pincers substantially can satisfy operation, and the hemostatic method only limits to oppress at present or vasoconstrictor such as interpolation epinephrine in cotton sheet.Chang Yong bipolar electrocoagulator is the tweezer formula clinically, and dark in narrow and small zone in the nose skull base surgery is because tweezer formula bipolar electrocoagulator two arm rear ends are thicker, so stop the visual field after inserting nasal cavity; In addition, because the activity of tweezer formula bipolar electrocoagulator two arms usually is subjected to the influence of nasal cavity inherent structure, be difficult to nasal cavity, the nose skull base surgery is offered help.Monopolar electrocoagulation is because wound is not selected.Developed double-pole electric coagulation forceps at laparoscopic surgery and neurosurgery in recent years, lead is placed in the sliding bar, two teeth that tighten up double-pole electric coagulation forceps by the pulling sliding bar carry out electricity with fixed attention, it is straight shape, when tightening up two teeth of double-pole electric coagulation forceps, hands will cooperate and moves forward, in the art chamber of the narrow and small fragility of nose basis cranii, operation is had relatively high expectations, and its shape is single, the clamping dynamics is less, so can not be applicable to angle and the stronger and limited space of rigidity that the nose skull base surgery is changeable, because nose skull base surgery art district is narrow and small, the art district of different parts needs difform operating theater instruments to handle, at present, lack clinically and a kind ofly can handle the hemorrhage bipolar electrocoagulator of different parts.

The utility model content

In view of above problem, main purpose of the present utility model provides a kind of stinging with operation and clamps the thread type double-pole electrocoagulator that is used.

For this reason, this utility model provides a kind of thread type double-pole electrocoagulator, comprises a pair of electriocoagulator, wherein, described each electriocoagulator is formed by electrode tip, electrode sleeve and binding clip cover, and the back side of described electrode tip is expanded and is enclosed within the described electrode sleeve, and described binding clip cover is expanded at the back side of described electrode sleeve.

Preferably, the front end of described electrode tip is outstanding forward.

Preferably, be lined with potsherd between the rear wall of described electrode tip and described electrode sleeve.

Preferably, described binding clip cover is pocket-like, and opening in the wings.

Preferably, walking has lead in the rear wall of described binding clip cover.

Can match with the pincers of stinging of different shape according to thread type double-pole electrocoagulator of the present utility model, be suitable for the electric coagulation hemostasis of all places in the nose basis cranii, and simple in structure, with low cost, for disposable use, easy to use.

Description of drawings

With reference to accompanying drawing, from as an example following but be not used in the description of restriction this utility model purpose, will become more obvious according to the feature and advantage of thread type double-pole electrocoagulator of the present utility model, wherein:

Fig. 1 is the general illustration of this utility model thread type double-pole electrocoagulator;

Fig. 2 is the amplification view of the electriocoagulator of thread type double-pole electrocoagulator shown in Figure 1;

Fig. 3 is the schematic perspective view of the electriocoagulator of thread type double-pole electrocoagulator shown in Figure 1;

Fig. 4 schematically shows first kind of embodiment according to thread type double-pole electrocoagulator of the present utility model;

Fig. 5 schematically shows second kind of embodiment according to thread type double-pole electrocoagulator of the present utility model.

The specific embodiment

As shown in Figure 1, be made up of a pair of electriocoagulator 1 and lead 6 according to thread type double-pole electrocoagulator of the present utility model, attaching plug 7 makes electriocoagulator 1 and lead 6 link to each other with the main frame of bipolar electrocoagulator.Electriocoagulator 1 is made up of electrode tip 2, electrode sleeve 5 and binding clip cover 3, and slightly expand at the back side of electrode tip 2, is enclosed within the electrode sleeve 5.It is binding clip cover 3 that pocket-like is expanded at the back side of electrode sleeve 5, and binding clip overlaps 3 openings in the wings, and lead 6 travelings are in the rear wall 4 of binding clip cover 3.The material of electrode sleeve 5 and binding clip cover 3 is medical macromolecular materials.

As shown in Figure 2, the front end of electrode tip 2 is outstanding forward, and the back side is expanded and is enclosed within the electrode sleeve 5, is lined with potsherd 8 between the rear wall of electrode tip 2 and electrode sleeve 5.

As shown in Figure 3, the front end of electrode tip 2 is outstanding forward, and the back side is expanded and is enclosed within the electrode sleeve 5, and it is binding clip cover 3 that pocket-like is expanded at the back side of electrode sleeve 5, and binding clip overlaps 3 openings in the wings, and lead 6 travelings are in the rear wall 4 of binding clip cover 3.

As shown in Figure 4, when thread type double-pole electrocoagulator is applied to common when pincers of stinging, binding clip cover 3 is enclosed within on the binding clip 17 of stinging pincers, connect the main frame of bipolar electrocoagulator by attaching plug 7, tighten up flexible handle 15 and fixed handle 14, the effect by joint 13 and joint 12 promotes motion bar 11 and moves forward with respect to fixed bar 16.By the effect in joint 10 and joint 9, it is closed to another binding clip 17 motions to promote a binding clip 17, makes two electrode tips 2 form the loop by intermediary tissue, carries out electric coagulation hemostasis.

As shown in Figure 5, when the motion bar 11 of stinging pincers and fixed bar 16 during for tubulose, lead 6 travelings can be made into double-pole electric coagulation forceps in tube chamber, and this structure is more compact, but can not with various sting to clamp cooperate, can only be applicable to specific operative site.All the other same Fig. 4.

The following describes concrete working condition of the present utility model.

When needing to stop blooding in the art, binding clip cover 3 is enclosed within respectively on two binding clips stinging pincers accordingly, two electrode tips 2 are relative, because binding clip cover material is medical macromolecular materials, certain elasticity arranged, can make its sting on the binding clip fixing reliable.To sting pincers and go deep into the art chamber, electrode tip 2 clampings are wanted to sting tightly behind the electric tissue that coagulates, start the bipolar coagulation switch, and carry out electricity and coagulate.After electricity condensed and restraints, desirable lower pliers head cover was stung pincers and can be continued to undergo surgery as operating theater instruments.Thread type double-pole electrocoagulator of the present utility model can match with the pincers of stinging of different shape.

When operation finishes, take off thread type double-pole electrocoagulator, handle getting final product by medical waste from stinging pincers.

Although described preferred implementation of the present utility model here; but for the person of ordinary skill in the field; do not departing under the spirit and scope of the present utility model; can on structure and parts relationship, make various variations, and not break away from the protection domain of the present utility model that limits by following claims.
