Description

Polyp resection device

Technical Field

The present invention provides a polyp cutting device, and more particularly, to a polyp cutting device which can easily cut a polyp, stably receive the polyp, and prolong the service life.

Background

In recent years, with the development of endoscopic examinations and the increase of cases discovered early in the treatment of benign or malignant tumors such as polyps growing in digestive tracts of body cavities such as esophagus, stomach, and large intestine, cases of excision and section collection of polyps and tumors by an endoscope have been rapidly increasing. In particular, endoscopic polypectomy is a low-infection treatment, and therefore its applicability is expanding, and the increasing number of polyps and cancer cases with aging society, and such surgery and its related tools are rapidly spreading.

For polypectomy, the frequently used tools, in addition to the endoscope and the electric scalpel, are matched with a tool for taking out the polyp, so that the use frequency is correspondingly improved, however, the polyp is small in size, once the polyp is cut out, the time is relatively wasted in searching for the picking action, and therefore, an appliance integrating the electric scalpel and the taking-out tool (such as a mesh bag) is produced correspondingly. The operation mode is mainly that polyps can naturally fall into the mesh bag when being cut off, so that the problem of time waste is solved.

However, the above-mentioned two-in-one electric knife and removal tool has the following problems and disadvantages to be improved when used:

first, the electric knife and the removing tool are commonly disposed on a ferrule, and when the electric knife is electrically heated, the removing tool often touches the electric knife, which is damaged by heat.

Secondly, the cutting action of the electric knife is retracted to the handle by the traction of the back end copper wire or the net wire, but the retraction will also be accompanied with the taking-out tool, which leads to the deformation of the taking-out tool and increases the probability of damage by touching the electric knife.

How to solve the above-mentioned problems and deficiencies is a direction in which the authors of the present invention and the related manufacturers engaged in the industry need to research and improve.

Detailed Description

To achieve the above objects and advantages, the present invention provides a technical means and a structure, which will be described in detail with reference to the accompanying drawings for the purpose of fully understanding the features and functions of the preferred embodiments of the present invention.

Referring to fig. 1 to 3, it can be clearly seen that the present invention includes:

a connecting rod body 1, wherein the connecting rod body 1 is internally provided with at least one bundling space 11;

at least one flexible conductive piece 2 movably penetrating through the connecting rod body 1, and the flexible conductive piece 2 is movably accommodated in the contracting space 11;

at least one power supply device 3 electrically connected to the flexible conductive member 2;

a ring body 21 defined on the flexible conductive device 2 and located at one side of the connection rod body 1;

a plurality of thermal cutting pieces 4 arranged on the ring body part 21 and electrically connected with the power supply device 3;

at least one combining and fixing piece 5 fixed at one end of the ring body part 21 departing from the connecting rod body 1, and the combining and fixing piece 5 is provided with at least one buckle piece 51;

at least one bearing assembly 6 arranged on the ring body part 21 and the combining and fixing piece 5;

at least one isolation component 22 covering the ring body 21 for isolating the thermal cutting member 4 and the receiving component 6; and

a contracting device 7 disposed on one side of the connecting rod 1 and connected to the flexible conductive member 2, wherein the contracting device 7 includes a fixing portion 71, an operating portion 72 disposed on the fixing portion 71, and at least one limiting portion 73 disposed on the connecting rod 1, the fixing portion 71 is used for fixing the flexible conductive member 2, the operating portion 72 is used for a user to perform a push-pull operation to link the flexible conductive member 2, and the limiting portion 73 is used for assisting the user to operate the relative displacement between the fixing portion 71 and the connecting rod 1.

With the above description, the structure of the present technology can be understood, and according to the corresponding coordination of the structure, the advantages of easy polyp excision, prevention of mesh bag (holding component 6) damage, and prolonged service life can be achieved, and the detailed description will be described below.

Referring to fig. 1 to 6, when the above components are combined, it is clear from the drawings that the polyp resection device of the present invention also integrates the thermal resection component 4 (electrotome) and the receiving component 6 (taking-out tool), and operates the flexible conductive component 2 by the bundling device 7 to resect and recover the polyp 8, but the present invention further utilizes the combination of the fixing component 5 to change the bundling mode of the flexible conductive component 2, and cooperates with the isolation action of the receiving component 6 and the thermal resection component 4 to effectively solve the problem of the mesh bag being damaged by heat. The flexible conductive device 2 of the present embodiment may be implemented in a manner that two end portions are respectively fixed on the combining and fixing member 5 and penetrate through the connecting rod body 1, but the present embodiment is implemented in a manner that a middle section is fixed on the combining and fixing member 5, and two end portions penetrate through the connecting rod body 1; similarly, the isolation component 22 may be implemented by completely covering the flexible conductive member 2 or covering the flexible conductive member in two sections (only the portion of the thermal cut-off member 4 is exposed), and implemented by using an insulator material; the power supply device 3 can be a battery disposed in the connection rod 1, but the embodiment is implemented by an electric wire connected to an electric burning knife device; the thermal cutting element 4 is implemented by a monopolar electric knife or a bipolar electric knife; in the embodiment, the fixing member 5 is fixed to one end of the ring body 21 and the connecting rod 1.

Specifically, the present invention is generally used in conjunction with an endoscope 9, so that the polyp 8 of each part of the body can be removed, when the present invention is used, the connecting rod 1 is held by hand, the ring body 21 and the receiving member 6 are extended into the body from the opening (such as an incised wound) of the body, and the ring body 21 is surrounded outside the polyp 8, so that the receiving member 6 is ready to stand by below the polyp 8 (as shown in fig. 4), and then, as shown in fig. 5, after the power supply device 3 is powered on to heat the thermal removal member 4, the user operates the restraining device 7 to pull backward, so as to interlock the flexible conductive member 2, and the restraining operation can be pulled backward by the finger hooking operation portion 72 to interlock the fixing portion 71 and pull both ends of the flexible conductive member 2, and the limiting portion 73 can be hooked by the other two fingers of the same hand, so as to assist the user to operate the relative displacement between the fixing portion 71 and the connecting rod 1, so that the user can complete the pulling operation of the restraining device 7 with one hand.

As shown in fig. 6, when the bundling device 7 is operated, one end of the ring body 21 is tightly fixed by the fixing member 5 and cannot move, and the other end of the ring body contracts into the bundling space 11, so that the ring body 21 is caused to contract inwards due to the drawing action to form two parallel straight lines which are close to each other, thereby the heat cutting members 4 approach each other to complete the action of cutting off the polyp 8, and the supporting member 6 is used for collecting the polyp 8 along the trend while the polyp 8 is cut off, so as to achieve the purposes of easily cutting off the polyp 8 and quickly recovering the polyp 8, and due to the contraction action change of the flexible conductive member 2 and the isolation effect of the isolation member 22, the supporting member 6 is effectively prevented from touching the heat cutting member 4, thereby solving the problem of heat damage of the supporting member 6, and further improving the stability of the supporting member 6 for receiving the polyp.

As shown in fig. 7 and 8, it is clear that the embodiment is similar to the above embodiments, and only the combining and fixing member 5a is a plurality of embodiments, in which the two combining and fixing members 5a are adjacently disposed on the outer side of the ring body portion 21a, and are shown in a manner that one end is combined to the fastening member 51a and the other end is combined to the connecting rod body 1 a. In the present embodiment, the receiving element 6a can be directly disposed on the combining fixture 5a without being disposed on the annular body 21a together with the thermal cutting element 4a, and although there is isolation protection of the isolation element 22a, the present embodiment is designed in a direct separation manner, so that when the thermal cutting element 4a is inwardly contracted, the receiving element 6a can be prevented from moving along with the inward contraction, the risk that the receiving element 6a touches the thermal cutting element 4a can be completely eliminated, and the polyp 8a can be ensured to fall into the receiving element 6 a.

As shown in fig. 9 to 12, it is clear that the embodiment is the same as the above embodiments, and only two ends of the combining and fixing member 5b are respectively fixed on the ring body portion 21b and the flexible conductive member 2 b. In this case, when the user operates the contraction device 7b to contract backwards, one side of the combination fixing member 5b adjacent to the connection rod body 1b contracts into the connection rod body 1b together with the ring body 21b, so that the connection rod body 1b presses the ring body 21b to draw inward, thereby connecting the thermal cutting member 4b to cut off the polyp 8b, and the bearing component 6b also gradually tightens the polyp 8b along with the contraction of the combination fixing member 5b to bear the polyp 8b and simultaneously contract the polyp 8b at the front end of the connection rod body 1b, so as to prevent the polyp 8b from shaking, thereby improving the stability of bearing the polyp, and the safety and convenience in operation.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, so that the present invention is not limited by the accompanying drawings.
