Description

Wire bipolar coagulator

technical field

The invention relates to a medical instrument for nasal endoscopic surgery, in particular to a line type bipolar electric coagulator.

Background technique

Transnasal endoscopic surgery is a milestone in rhinology surgery. After nearly 70 years of development, the surgical indications of nasal endoscopic surgery have been continuously expanded, and the restricted area of surgery has been continuously broken. For the treatment of nasal sinus tumors and skull base lesions, nasal Endoscopic technology has begun to show its advantages, which also put forward higher requirements for other surgical instruments. Among them, the development of surgical forceps is the most perfect, and various shapes of forceps can basically meet the needs of surgery, while hemostasis The current methods are limited to compressing or adding vasoconstrictors such as epinephrine to cotton pads. The bipolar coagulator commonly used clinically is forceps type. In the deep and narrow area of nasal skull base surgery, because the rear ends of the two arms of the forceps type bipolar coagulator are thicker, it blocks the field of view after being inserted into the nasal cavity; in addition, Because the activities of the two arms of the forceps bipolar coagulator are often affected by the inherent structure of the nasal cavity, it is difficult to provide assistance for nasal cavity and nasal skull base surgery. Unipolar coagulation is often not an option due to greater trauma. In recent years, bipolar coagulation forceps have been developed in laparoscopic surgery and neurosurgery. The wire is placed in the sliding rod, and the two teeth of the bipolar coagulation forceps are tightened by pulling the sliding rod to perform electrocoagulation. When tightening the two teeth of the bipolar coagulation forceps, the hand should move forward in coordination. In the narrow and fragile operation cavity of the nasal and skull base, the operation requirements are relatively high, and its shape is single and the clamping force is weak, so it is not applicable Due to the variable angle and strong rigidity of the nasal skull base surgery and the limited space, due to the narrow surgical area of the nasal skull base, surgical instruments of different shapes are required for different parts of the surgical area. At present, there is a lack of a clinically Bipolar coagulator for treating bleeding from different sites.

Contents of the invention

In view of the above problems, the main purpose of the present invention is to provide a wire type bipolar coagulator used in conjunction with surgical forceps.

To this end, the present invention provides a line type bipolar electrocoagulator, including a pair of electrocoagulation heads, wherein each electrocoagulation head is composed of an electrode head, an electrode sleeve and a clamp head cover, and the electrode head The enlarged back is covered in the electrode cover, and the back of the electrode cover is expanded to form the clamp head cover.

Preferably, the front end of the electrode head protrudes forward.

Preferably, a ceramic sheet is placed between the electrode head and the rear wall of the electrode sleeve.

Preferably, the pliers head cover is in the shape of a pocket with an opening at the rear.

Preferably, wires run in the rear wall of the pliers cover.

The wire type bipolar electrocoagulator according to the present invention can be matched with clamps of various shapes, and is suitable for electrocoagulation and hemostasis at various positions in the nasal skull base, and has a simple structure, low cost, is disposable, and is easy to use .

Detailed ways

As shown in Figure 1, the line type bipolar coagulator according to the present invention is made up of a pair of coagulation head 1 and lead wire 6, and power plug 7 connects the electrocoagulation head 1 and lead wire 6 with the host machine of bipolar electrocoagulator. The electrocoagulation head 1 is composed of an electrode head 2, an electrode cover 5 and a forceps cover 3. The back side of the electrode cover 5 expands into a pocket shape and becomes the clamp cover 3, the opening of the clamp cover 3 is at the rear, and the wire 6 runs in the rear wall 4 of the clamp cover 3. The material of the electrode cover 5 and the clamp head cover 3 is a medical polymer material.

As shown in FIG. 2 , the front end of the electrode head 2 protrudes forward, and the back is swollen to fit in the electrode sleeve 5 , and a ceramic sheet 8 is placed between the electrode head 2 and the rear wall of the electrode sleeve 5 .

As shown in Figure 3, the front end of the electrode head 2 protrudes forward, and the back is enlarged to be covered in the electrode cover 5. The back of the electrode cover 5 is expanded into a pocket shape to form a clamp cover 3, the clamp cover 3 opens at the rear, and the wire 6 runs in the clamp Inside the rear wall 4 of the headgear 3.

As shown in Figure 4, when the line type bipolar coagulator is applied to common pliers, put the pliers cover 3 on the pliers 17, connect the main unit of the bipolar coagulator through the power plug 7, and tighten The movable handle 15 and the fixed handle 14 push the movable rod 11 to move forward relative to the fixed rod 16 through the action of the joint 13 and the joint 12 . Through the action of the joint 10 and the joint 9, one forceps head 17 can be pushed to move and close to the other forceps head 17, so that the two electrode heads 2 can pass through the middle tissue to form a loop for electrocoagulation and hemostasis.

As shown in Figure 5, when the movable rod 11 and the fixed rod 16 of the pliers are tubular, the wire 6 runs in the lumen and can be made into a bipolar electrocoagulation forceps. This structure is more compact, but it cannot be used with various The bite forceps fit and can only be applied to specific surgical sites. The rest are the same as in Figure 4.

The specific working conditions of the present invention are described below.

When hemostasis is needed during the operation, the forceps head cover 3 is placed on the two forceps heads of the corresponding bite forceps respectively, and the two electrode heads 2 are opposite. Since the forceps head cover is made of medical polymer material, it has certain elasticity, which can make it bite Reliable fixation on the pliers. Deepen the forceps into the operation cavity, clamp the electrode head 2 to the tissue to be electrocoagulated, and then tighten it, and turn on the bipolar electrocoagulation switch to perform electrocoagulation. After the electrocoagulation is finished, the forceps head cover can be removed, and the bite forceps can continue to operate as a surgical instrument. The wire-type bipolar electrocoagulator of the present invention can be matched with jaws of various shapes.

At the end of the operation, remove the wire-type bipolar coagulator from the bite forceps and dispose of it as medical waste.

Although preferred embodiments of the present invention have been described herein, various changes in structure and relationship of parts can be made by those skilled in the art without departing from the spirit and scope of the present invention, without departure from the scope of protection of the present invention as defined by the following claims.
