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on the outer wall of the needle when the needle is inserted, and the supporting member is retracted when the needle is withdrawn.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 present invention relates to the field of medical devices, in particular to an ESD surgical tool, comprising 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 into the needle, and the supporting member is The needle unfolds as it withdraws and remains below the layer to be peeled. The ESD surgical tool provided by the present invention is more convenient and faster to operate than the conventional method of fixing the lesion with titanium clips or separating the lesion layer by injecting physiological saline, without frequent replacement and use of different instruments, which reduces the cost of surgery. Under the support of the support, the lesion can be resected and stripped more stably and accurately, which improves the quality of the operation, helps reduce the postoperative pain of the patient, improves the recovery rate of the patient and reduces the occurrence of complications Rate.

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...
