Abstract

The invention discloses an extractor for an endoscopic surgery capable of being operated by a single hand. The extractor comprises a clamp and a collection bag, wherein the clamp is provided with two groups of tong jaws for biting; the tong jaws are arranged into endoscopic surgery forceps through a tong jaw seat and a connecting rod structure; the tong jaws are controlled to bite and open through a handle at the tail end of the clamp; a penetrating hollow cavity is arranged in the collection bag along a bag opening; two groups of tong jaws are inserted into the hollow cavity from two directions separately; a safety rope is also arranged in the hollow cavity in a penetrating manner; and the safety rope is connected with the tong jaws of the clamp. According to the extractor, tissue removed in the endoscopic surgery operation is effectively prevented from remaining in a body; meanwhile, biting and opening of the bag opening of the collection bag are controlled by adopting the handle, so that the extractor can be operated by the single hand of a doctor in the tissue removal process. The extractor is very convenient to use; double hands of the doctors are liberated, the operation efficiency is improved and the workload of the doctor and the pain of a patient can be relieved.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to an object fetcher for endoscopic surgery that can be operated with one hand. Background technique [0002] With the development of endoscopic minimally invasive surgery, the object extractor, as a commonly used medical surgical instrument for taking out resected objects in endoscopic surgery, is more and more widely used. Most of the existing endoscopic object retrieval devices use the object retrieval bag to be assembled on the memory alloy ring, and then cooperate with the outer sleeve to control the opening and closing of the bag mouth. For example, the patents with the authorized announcement numbers CN104287782A and CN203263438U all adopt the above scheme . The retrieval device adopting this scheme is often due to the limited rigidity of the memory alloy ring on the retrieval bag itself. When the force is applied, the mouth of the retrieval bag will be deforme...
