application number: CN202010166108.3

Application name: bipolar electric treatment device

Filing date: 2020-03-11

Is applied for the division of the patent application.

Technical Field

The application relates to the technical field of medical instruments, in particular to a bipolar electric treatment device.

Background

Soft endoscopic surgery is becoming an increasingly common surgical mode in the fields of the current digestive tract, urinary tract, heart and lung and the periphery of blood vessels due to its minimal trauma and rapid recovery. In preoperative diagnosis of endoscopes, biopsy procedures are often required to be performed on suspected lesions in order to perform pathological analysis. The existing mode mainly comprises the steps of grabbing focus tissues through a biopsy forceps with a flexible shaft, wherein the grabbing process can damage blood vessels of submucosal layers to cause bleeding, and physiological burden is caused to a patient. On the other hand, since pathological analysis requires that the biological activity of the biopsy tissue is maintained, the temperature inside the forceps cup of the biopsy forceps cannot be too high or too low.

Chinese patent publication No. CN205107883U discloses a thermal biopsy forceps with insulating coating, which performs biopsy on target tissue by means of monopolar electric cutting, and the metal forceps cup and the negative plate attached to the human body form a high-frequency current loop, so that electrocautery cells between the metal knife edge of the cup body and the tissue break to form a cut, and in this process, blood vessels below the knife edge are simultaneously coagulated. However, the current loop of the monopolar device flows through a large range of the human body, and for cardiac pacemakers or ICDs (buried cardioverter defibrillators) implanted in patients, current may pass through the pacemaker loop, burn body tissue on the loop, and severe cases may burn the myocardium.

U.S. patent publication No. WO1994017741A1 discloses a bipolar biopsy instrument that connects two clamp cups to the positive and negative poles of a power source, respectively, thereby forming a high frequency current loop between the clamp cups, avoiding the impact on the cardiac pacemaker. However, because the current is concentrated between the two forceps cups, the energy is too concentrated, which easily causes the biopsy tissue to lose biological activity; on the other hand, because the outer diameter of the biopsy forceps is small, short circuit is easy to form between two forceps cups in the existing design, so that biopsy is invalid.

Chinese patent application No. cn201080032888. X also discloses a high-frequency treatment tool, which belongs to a bipolar tool solution, and includes a pair of power supply lines, a first end portion of which is rotatably connected to the rotation shaft, a second end portion of which is connected to a power source, and the pair of power supply lines are electrically connected to the electrode portions of the pair of forceps members, respectively. In order to allow the endoscopic treatment device to freely pass through the endoscopic forceps channel, the outer diameter of the endoscopic treatment device is limited by the inner diameter of the endoscopic instrument channel, and is usually 2.8mm or less. The arrangement of more than two steering/power supply lines is inconvenient for the user to perform a rotating operation capable of timely feedback on the distal processing part at the proximal end, and is unfavorable for the development of the operation.

Detailed Description

The application will now be described in more detail with reference to the accompanying drawings, to which it should be noted that the description is given by way of illustration only and not by way of limitation. Various embodiments may be combined with one another to form further embodiments not shown in the following description.

Referring to fig. 1, in an embodiment of the present application, a bipolar electro-processing apparatus 1000 is provided, where the bipolar electro-processing apparatus 1000 includes: a binding clip mechanism 100, a sheath mechanism 200, an electrode mechanism 300, a handle mechanism 400, and a bipolar linkage structure mounted in the sheath mechanism 200. The clamp head mechanism 100 is arranged at the right end part of the sheath tube mechanism 200 and can rotate relative to the sheath tube mechanism 200; the left end of the sheath mechanism 200 is mounted on the electrode mechanism 300, and the sheath mechanism 200 is in communication with the electrode mechanism 300; the handle mechanism 400 is mounted on the left side of the electrode mechanism 300 and is rotatable relative to the electrode mechanism 300. The bipolar linkage includes a conductive pull wire 240, an insulated connector 220, and an actuating member 130, the actuating member 130 including a first conductive actuating member 131 and a second conductive actuating member 132 (see fig. 11).

Referring to fig. 2 to 5, the clamp head mechanism 100 includes: the two insulating pincer cups 110 and the insulating cup holders 120 are specifically as follows:

the opposite sides of each of the insulating forceps cups 110 are formed with cups 111 for receiving the grasped biopsy sample, the respective cups 111 are disposed opposite to each other, and the respective cups 111 are shaped to fit, the cups 111 being located at end positions of the sides of the insulating forceps cups 110; the outer sides of the insulating clamp cups 110 are provided with conductive layers (not shown), and the conductive layers of each insulating clamp cup 110 can be respectively connected with a control piece (130) so as to form a high-frequency current loop on the outer sides of the two insulating clamp cups 110; in addition, the inner side wall of the cup 111 is always kept in an insulating state and the cutting edge 1111 of the cup 111 is also always kept in an insulating state, so that the biopsy sample grasped into the cup 111 is kept in an insulating state, and the loss of biological activity of the biopsy sample in the cup 111 due to the excessive concentration of electric energy on the outer side wall of the insulating clamp cup 110 can be avoided. In addition, the conductive layer laid on the outer side of the insulating pincer cup 110 may be laid by electroplating, spraying, or the like.

It will be appreciated that when two of the forceps cups 110 are changed from the open configuration to the occluded configuration, the cutting edge 1111 on each of the forceps cups 110 will cut the lesion tissue to obtain a biopsy sample; meanwhile, when the two insulating forceps cups 110 are in the occlusion state, the two cup bodies 111 are mutually surrounded to form a sealed cavity in the insulation state, and the biopsy sample is accommodated in the sealed cavity, so that the biopsy sample is isolated from the heating part of the insulating forceps cups 110, and the biological activity of the biopsy sample can be effectively ensured.

It can be appreciated that, when the respective insulating forceps cups 110 are in the engaged state, the conductive layers outside the respective insulating forceps cups 110 are electrically connected to different electrode circuits (positive electrode circuits or negative electrode circuits) through the respective manipulating members 130, and the outer diameter dimensions of the respective insulating forceps cups 110 are small, which easily causes a short circuit phenomenon, and thus easily causes biopsy failure. Thus, the cutting edge 1111 of each cup 111 is always kept in an insulated state, so that electrical contact between the cups 111 in the engaged state can be avoided, and thus, a short circuit phenomenon can be prevented, and a biopsy failure problem can be avoided.

It will be appreciated that, as shown in fig. 3, the cutting edges 1111 of the cup 111 are arranged in a tooth shape, so that the two insulating forceps cups 110 can be mutually engaged by the cutting edges 1111 arranged in a tooth shape, thereby facilitating the electrocoagulation operation on the bleeding part. In addition, as shown in fig. 4, the cutting edge 1111 of the cup 111 may be designed as an annular cutting edge, which facilitates cutting of the sample to be biopsied. The shape of the cutting edge 1111 of the cup 111 is not limited to the shape shown in fig. 3 or 4, and those skilled in the art may design the cutting edge 1111 in other types of shapes to satisfy the operations of electrocoagulation of a bleeding site or electric cutting of a biopsy sample.

Wherein, one end of each insulating forceps cup 110 far away from the cup body 111 is hinged at the same end of the insulating cup holder 120, and the positions where each insulating forceps cup 110 is hinged with the insulating cup holder 120 are arranged in parallel and at intervals, namely; the ends of the respective insulating pincer cups 110 hinged to the insulating cup holders 120 are alternately and alternately arranged to avoid a short circuit phenomenon caused by the cross contact of the conductive layers outside the respective insulating pincer cups 110.

It will be appreciated that the insulating layer is not applied to the position where the actuating member 130 with the insulating layer applied thereto is hinged to the insulating clamp cup 110, namely: the operating element 130 with the insulating layer is always electrically connected with the conductive layer of the insulating clamp cup 110.

It will be appreciated that, based on the push-pull process of each of the operating members 130, each of the insulating clamp cups 110 can be operated to open or engage, i.e., a worker can operate each of the operating members 130 by other structures to adjust each of the insulating clamp cups 110 from an open state to an engaged state (or vice versa).

In addition, a plurality of first openings 122 are formed on two opposite sides of the end portion of the insulating cup holder 120, each first opening 122 is disposed in parallel with each other at intervals, each first opening 122 is communicated with the second through hole 121, and each insulating pincer cup 110 is correspondingly disposed in each first opening 122.
