Embodiment Construction

[0016] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figure 1 to Figure 4 As shown, an ESD surgical tool of the present invention includes a needle and a detachable supporting member arranged on the needle, the supporting member is gathered on the outer wall of the needle when the needle is inserted, and the supporting member is retracted when the needle is withdrawn. Unfold and stay below the layer to be peeled off.

[0018] It can be seen from the above description that the beneficial effect of the present invention is to provide an ESD surgical tool, including a needle and a detachable supporting member arranged on the needle. surface, which is beneficial for the needle to enter the lesion; the submucosal injection such as normal saline can be injected first to make the submucosa bulge,...

Abstract

The invention relates to the field of medical instruments, and in particular to an endoscopic submucosal dissection (ESD) surgical tool. The ESD surgical tool comprises a needle head and a support piece which is detachably arranged on the needle head, wherein the support piece is folded on the outer wall of the needle head when the needle head is inserted, and the support piece is unfolded and isleft below a to-be-stripped layer when the needle head is withdrawn. Compared with conventional modes that a lesion part is fixed by using a titanium clamp, a lesion layer is separated by injecting physiological saline and the like, the ESD surgical tool provided by the invention is more convenient and quicker to operate and does not need frequent replace and use of different instruments, so thatsurgical cost is reduced. The EDS surgical tool can be used to more stably and accurately excise and strip the lesion part under supporting action of the support piece, so that surgical quality is improved, postoperative pain of a patient is reduced, the rehabilitation rate of the patient is improved, and simultaneously the incidence rate of complications is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an ESD operation tool. Background technique [0002] With the development of digestive endoscopy technology, the detection rate of early digestive tract cancer and precancerous lesions is increasing year by year. At present, endoscopic submucosal dissection is the most commonly used method for the treatment of early gastric cancer and precancerous lesions. Endoscopic submucosal dissection (Endoscopic submucosal dissection, ESD) is currently a mature technique for the endoscopic treatment of early cancers of the digestive tract (esophagus, stomach, and colorectum). It is a low-risk, low-injury, and practical technique. Feasible treatment methods are mostly used to resect lesions with a base area larger than 2cm, so that more early digestive tract cancers and other lesions can be completely resected at one time under endoscopy, eliminating the pain of open surgery and organ rese...
