Embodiment 1

[0033] Please see attached figure 1 , with figure 1 It is a three-dimensional schematic diagram of a novel endoscopic mucosal dissection device of the present invention. A novel endoscopic submucosal dissection device, comprising a main body 1, an injection module 2, a cutting module 3, and a traction module 4; Cutting module 3, traction module 4; The injection module 2 includes a plurality of syringes, the syringe is a tubular structure with an injection needle tube, which can inject liquid into the target object, that is, the object to be cut, such as mucous membrane, etc. Four groups are used in this embodiment The composition of the syringe, because it is understood that it can also select different groups of syringes according to actual needs, such as 2 groups, 3 groups, 6 groups, etc., and in some preferred embodiments, the syringe and the main body 1 The channels are detachably connected and can be flexibly configured according to needs; the injector of the injection ...

Embodiment 2

[0037] Please see attached image 3 , with image 3It is a schematic diagram of another novel endoscopic mucosal dissection device of the present invention. This embodiment is basically the same as Embodiment 1, and the difference is that the end of the main body 1 described in this embodiment also has an imaging device 11 and an illuminating device 12, and its imaging device 11 and illuminating device 12 can have multiple groups. , it is convenient to provide a multi-angle field of view during the surgical operation, so as to avoid excessive adjustment of the main body 1 and adsorption fixation.

Embodiment 3

[0039] Please see attached Figure 4 , with Figure 4 It is a schematic diagram of a surgical instrument of the present invention. A surgical instrument, characterized in that it includes a novel endoscopic mucosal dissection device, a control system 5, and a connection system 6, and the control system 5 is connected to the novel endoscopic mucosal dissection device through the connection system 6; the control system 5 is used for Provide high-frequency electric cutting power supply, traction source, that is, negative pressure suction source, etc.; the surgical instrument can provide a stable working environment, energy source, operation basis and stable control for the new endoscopic mucosal dissection device.

[0040] The surgical instrument of the present invention includes a novel endoscopic mucosal dissection device, which can determine the boundary and range of mucosal dissection during use, push out the syringe through the first channel of the main body, observe under ...

Abstract

The invention relates to a novel endoscopic mucous membrane stripping device which comprises a main tube body, an injection module, a cutting module and a traction module. A plurality of channels are formed in the main pipe body to accommodate the injection module, the cutting module and the traction module; the injection module comprises a plurality of injectors and can inject liquid into a target object; the cutting module comprises a plurality of cutters used for cutting a target object, and the cutters are electrode guide wires, are uniformly arranged around the axial direction of the main pipe body and are arranged on the outer side of the injection module; a net-shaped structure is formed among the cutters; the traction module is arranged in the center of the main tube body, movably connected with the main tube body and is a negative pressure suction tube, the diameter of an end opening of the tail end of the traction module is larger than that of the tube body, the traction module is in a bowl-shaped inverted buckle shape, and the traction module forms a negative pressure traction effect on a target object through an external negative pressure source. The device has the advantages that ESD operation steps can be simplified, simple and convenient one-time excision and complete recovery of excised lesions under an endoscope are achieved, and lesion residues are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel endoscopic mucosal dissection device. Background technique [0002] ESD (endoscopic submucosal dissection, ESD)-based minimally invasive digestive endoscopic treatment has become a choice, or even a priority, for the treatment of early gastrointestinal mucosal tumors and some submucosal tumors. For early cancer and precancerous lesions of the digestive tract without lymph node metastasis and shallow invasion depth, as well as submucosal tumors of the digestive tract, ESD can be used to achieve complete resection and curative resection. At present, the conventional ESD operation is to separate the mucosal layer from the muscular layer by submucosal injection of relevant agents, point out the resection boundary point by point with a needle-type incision knife, and then use a needle-type knife to make an opening, and then use an IT knife to incise and peel off. Howe...
