Description

Rotary closed bipolar electrocoagulation hemostasis device with water dripping and sucking functions

Technical Field

The utility model belongs to a medical appliance, in particular to a device for assisting hemostasis in surgical operation.

Background

The bipolar electrocoagulator is an electrosurgery equipment formed by connecting two metal electrodes with a high-frequency generator by means of conducting wire, and its working principle is that a high-frequency high-voltage current is passed through the conductive tissue with a certain impedance between two electrodes to produce high-temp. to make tissue protein coagulate and seal blood vessel so as to obtain good hemostatic effect. The bipolar coagulation is safe, reliable, practical, simple and convenient, is suitable for multiple surgical applications in multiple disciplines, has emerged since the last 40 th century, and has become the most common hemostasis technical equipment for modern surgical operations. Bipolar electrocoagulators are of many kinds, and can be roughly divided into several major categories: a nipper type bipolar electrocoagulator, a gun type bipolar electrocoagulator and a push-open type bipolar electrocoagulator. The forceps type bipolar coagulator is the first bipolar coagulation device which appears and is widely applied, has different shapes such as straight forceps, bent forceps, gun-shaped forceps and the like with different sizes, and is mainly suitable for superficial open surgery. These different bipolar coagulators have been widely used clinically, but also suffer from a number of disadvantages: for example, the working electrode of the electrocoagulation is easy to form eschar and adhere to tissues, so that the hemostatic effect is influenced; the conventional electric coagulation forceps are large and short, and are difficult to enter a tiny and deep operation part for operation, and the like. In order to solve the problem that the electrode is easy to coke and crust and adhere, some products are designed into bipolar coagulation with a dripping function or are continuously flushed with water during use. The utility model discloses a utility model application "a drip control formula bipolar coagulation forceps" (application number: 200620088624) discloses a drip control formula bipolar coagulation forceps, including the bivalve tweezers body and tweezers handle, its characterized in that, the electric coagulation forceps still includes the liquid control key that sets up on the tweezers handle and the liquid controlling means who is connected with the tweezers handle, is the electricity between liquid control key and the liquid controlling means. When the electric coagulation forceps are used, the liquid control mechanism is closed under the normal condition, the electric coagulation forceps can be used as common forceps, and no liquid flows out to influence the operation visual field. When tissue is needed to be subjected to electric coagulation hemostasis, the touch control key can be pressed, the liquid control device is started at the moment, and liquid flows to the electric coagulation forceps through the control device and the conduit, so that the function of the dripping bipolar electric coagulation forceps is realized. The invention relates to a push-pull type water dripping controllable non-stick bipolar electric coagulation forceps (application number 201210531547.5), which mainly aims to improve a water dripping control mode. It is characterized in that: the forceps tail seat cushion and the embedded pipe groove, the embedded rod groove, the embedded block groove and the limiting groove on the forceps tail seat cushion; a forceps tail seat cover; a gland at the side edge of the limiting groove; the side surface of one end of the pushing and poking rod in the embedded rod groove and the limiting convex column on the pushing and poking rod groove are designed into a concave arc-shaped surface, and the upper surface of the end part of the other end is raised; an extrusion shifting block is arranged in the embedding block groove, the rear end of the extrusion shifting block is designed into an arc-shaped surface, and the front end of the extrusion shifting block is designed into a sharp wedge-shaped top. Simple structure, convenient and reliable use and reduced manufacturing cost. "Rotary drip controlled non-stick bipolar coagulation forceps" (application No. 201210531548), similar to the above-mentioned patent technology. The invention discloses a non-adhesive bipolar coagulation forceps (application number 201310353449), which comprises a left forceps rod, a right forceps rod and forceps tips fixed on the heads of the forceps rods, wherein the inner sides of the forceps rods are provided with lead grooves, conductive wires are arranged in the lead grooves, the conductive wires are hollow copper tubes, one ends of the conductive wires are fixedly connected with the forceps tips, the other ends of the conductive wires are connected with leads used for connecting an electrocoagulator main machine, and a water dropping tube interface connected with medical water delivery equipment is arranged. The conductive wire can be used for conducting electricity and can also be used as a water dropping pipe. At present, various commercially-applied bipolar coagulation forceps for clinical application have large volumes or diameters and lack the specifications of small and deep operation in the surgical field.

The gun type bipolar coagulator is provided with a relatively slender connecting rod and is suitable for deep operations such as various operations under an endoscope. However, the gun-type bipolar electrocoagulator has a complicated structure, and particularly, the working electrode movably connected with the front end of the gun-type bipolar electrocoagulator not only has insulation and considerable strength, but also can be flexibly opened and closed, and the movable joints of the electrocoagulation end and the handle end of the gun-type bipolar electrocoagulator are particularly easy to damage, so that the gun-type bipolar electrocoagulator is difficult to be manufactured very finely. Such structures are for example described in US5578052, chinese patents CN201720707252, CN201610191145 and CN 201020217396. The push-open type bipolar electrocoagulator adopts a mode that the two electrodes at the front end adopt a sleeve and elastic opening, the electrodes push out the sleeve and are in an open state under the elastic action, and the electrodes retract into the sleeve and are in a closed state, so that the relative structure is simpler. For example, the Chinese patent application 'bipolar coagulation forceps' (application number: 201310050385) comprises forceps, a shell, a sleeve, a forceps propelling device and a circuit system, wherein the sleeve is connected with the shell, the forceps comprise a forceps head and a forceps rod, the forceps pass through a pipe hole of the sleeve, the front end part of the forceps head extends out of a pipe orifice of the sleeve, and the forceps rod is connected with the forceps propelling device; when the pliers propelling device is in a propelling state, the pliers rod extends outwards, the pliers head completely extends out of the pipe orifice of the sleeve, the pliers head is opened, when the pliers propelling device is in a withdrawing state, the pliers rod retracts inwards, and the rear end part of the pliers head retracts into the sleeve to close the pliers head; the clamp rod is electrically connected with the circuit system, and the circuit system is externally connected with a power supply. Can easily grasp the tissues such as blood vessels and the like to carry out operations such as separation, electrocoagulation, cutting and the like. Chinese utility model patent application CN201520702218 also adopts the same structure. The working electrode at the front end of the push-open type bipolar electrocoagulator does not need to be provided with a rotating shaft and a pivot shaft or a joint, and the structure is simple and durable. However, the electrode needs to be retracted in the clamping process, and the friction force is large, so that accurate operation is difficult to perform, and the clinical application is limited. In addition, in the application of bipolar coagulation hemostasis, a suction tube is required to suck and remove wound blood or other liquid simultaneously in order to see a bleeding point. To solve this problem, there are also bipolar electrocoagulation products designed with a suction tube. Such as "suction type bipolar coagulation forceps" (application No. 201420589179.4); "bipolar coagulation forceps with suction" (application No. 201520132264.2), and the like. The bipolar coagulation device with water dripping, suction tube or both needs to increase the volume and diameter of the electrode, so that the bipolar coagulation device is more unfavorable for entering tiny and deep operation field operations, such as certain neurosurgery operations, nasal and cranial endoscopic operations, ear microsurgery operations, certain delicate endoscopic surgery operations and the like. In response to the above problems, the inventors previously filed 1 application for "double tube rotary-shaft bipolar electrocoagulation" (application No. 201710885571.1) to improve the above problems. For further improving the vascular sealing function of bipolar coagulation, prevent eschar adhesion, strengthen hemostatic effect and more simple and convenient practicality, the utility model discloses following solution has been carried out.
