Background
With the wide development of endoscopic treatment, endoscopic high-frequency electrosection and electrocoagulation become more popular. Local bleeding is a common complication of endoscopic treatment. The high-frequency hemostatic forceps clamp bleeding blood vessels or focus under the direct view of an endoscope, and can achieve the purpose of hemostasis by supplying high-frequency current, so that the high-frequency hemostatic forceps are common instruments for hemostasis under the direct view of the endoscope, and have strong practical value clinically; electric polypectomy is a common operation in clinic, and usually involves biting the polyp with hot biopsy forceps and applying a high-frequency current for electric excision.
The application number is 201921868886.6's chinese patent discloses a rotatable hemostatic forceps, sliding sleeve is equipped with the slip handle on the handle, the electrode that is used for putting through the high-frequency electricity sets up on the slip handle through thread tightening with the electrode fixing base, electrode fixing base and dabber are connected, the dabber near-end is connected with the slip handle, the dabber distal end is fixed with the rear end of binding clip subassembly, the binding clip subassembly includes two pincers cups, the cup, the connection piece, pin and push-and-pull rod, two pincers cups pass through the pin and articulate the front end at the cup, four-bar linkage is constituteed to two pincers cups and two connections, the opening and shutting of two pincers cups is controlled through this four-bar linkage of push-and-pull to the push-and.
This patent scheme is solved present rotatable blood coagulation pincers in the use, and the connecting wire winding problem that can produce during the rotation obviously improves apparatus operator's simple operation nature, but the doctor is carrying out electric excision under the scope, the electricity congeals in-process, and the pincers cup is the primary action part, consequently only need apparatus front end pincers cup department circular telegram can. At present, the head ends of the thermal biopsy forceps, the thermal hemostatic forceps and the like are all electrified to cause overlong electrified parts, and the overlong electrified head part is very easy to mistakenly touch human tissues and the surface of an endoscope during operation, so that a patient or the endoscope is scalded.
Disclosure of Invention
In view of the above, an object of the present invention is to provide a head insulation structure with rotation, which can only energize a forceps cup at the head end of a biopsy forceps, a thermal hemostat, etc., thereby avoiding the problem that the patient or the endoscope is scalded due to the fact that the excessively long energized head easily touches the body tissue and the surface of the endoscope by mistake.
The invention solves the technical problems by the following technical means:
a head insulation structure with rotation comprises a spring hose, wherein the outer wall of the spring hose is coated with a plastic coating layer, a rotation cylinder is fixedly arranged inside the spring hose in a penetrating manner, a push-pull rod is connected in the rotation cylinder in a sliding manner, and a tong head assembly is arranged on the push-pull rod; the binding clip subassembly includes two pincers cups, two connection pieces, insulating cup seat and pin, and two pincers cups pass through the pin and articulate the front end at the insulating cup seat, and four-bar linkage is constituteed to two pincers cups and two connection pieces, the push-and-pull rod is with two the connection piece is articulated, the opening and shutting of two pincers cups of push-and-pull four-bar linkage control is passed through to the push-and-pull rod, the one end that the insulating cup seat was kept away from to the push-and-pull rod is provided with the dabber mounting groove.
Furthermore, an annular bulge is arranged on the push-pull rod, an insulating sleeve is sleeved on the rotating cylinder between the annular bulge and the insulating cup seat, one side of the annular bulge abuts against the end part of the spring hose, the other side of the annular bulge abuts against the insulating sleeve, and the inner wall of the insulating sleeve is in sliding connection with the outer wall of the spring hose. So, can utilize insulating cover to carry out spacing to the rotary drum.
Furthermore, a boss is arranged at the end part of the push-pull rod close to the insulating cup seat, a groove is arranged in the insulating cup seat close to one end of the insulating sleeve, and the boss is abutted to the groove. So, can realize carrying out axial further spacing to rotatory section of thick bamboo, avoid rotatory section of thick bamboo to take place to rock in rotating.
Further, the insulating cup holder and the insulating sleeve are integrally formed into a cup holder sleeve, and the cup holder sleeve is an insulating cup holder sleeve. Insulating cup and insulating cover integrated into one piece are insulating cup cover, can be better carry out the axial spacing to a rotatory section of thick bamboo, stability when the operation is better.
Further, the insulating cup seat sleeve is a ceramic cup seat sleeve. The ceramic cup seat sleeve has good insulation performance and can isolate the passing of current.
Further, the insulating cup seat sleeve is a stainless steel cup seat sleeve, and a ceramic cup sleeve is sleeved on the outer wall of the stainless steel cup seat sleeve.
