Description
Technical Field
The utility model belongs to the technical field of snare, concretely relates to medical multi-functional tissue snare.
Background
A snare is an instrument for ligaturing blood vessels, polyps or other pipeline structures by tightening a sliding knot which is made of absorbable or synthetic threads in advance by a nylon rod, is convenient to operate, and is applied to various endoscopes (gastrointestinal endoscopes) and abdominal surgeries under laparoscopes.
The snare has the advantages of safety, convenience and economy. (1) Safety: the snare is made of an absorbable wire, and has small reaction to human tissues after being placed in a body; the operation is reversible, and the ligation position can be directly cut off when not satisfied; the cutting force to the tissue is smaller than that of the titanium clip, so that the tissue is not easy to be cut off; (2) convenience is realized: compared with the tissue suturing and ligating under a laparoscope, the operation of ligating by using the snare is simple and convenient, other special instruments are not needed, the operation time can be shortened, and especially, a beginner is easy to master and use; (3) economy: the snare is low in price, the application of the snare can correspondingly reduce the consumption of an endoscopic cutting closer (Endo-GIA) which is high in price, and the medical expense is reduced to a certain extent; (4) the multipurpose: the snare is used with an endoscope, and high-frequency current is used for removing polyps or other redundant tissues in the alimentary canal.
Endoscopic resection of polyps mainly comprises resection of mucosa by a transparent cap method, resection of mucosa by an injection method, resection of mucosa by a section by an injection method and the like.
The mucosal resection by the transparent cap method has the following advantages: the operation is simple and easy, and the success rate is high; can clean small flat lesions at one time; is especially suitable for small submucosal tumors; no special equipment is needed. The disadvantages are: the depth of resection is not easy to master; the muscle layer is easy to be injured, and the risk of bleeding and perforation is caused; is not suitable for large pathological changes, and is suitable for pathological changes of parts such as stomach, rectum and the like with thick muscle layers.
The principle of injection mucosectomy (PMR) is as follows: injecting normal saline and methylene blue into the submucosa to enable the base of the lesion to be raised (converting the flat lesion into the raised lesion); the lesion is sheathed with a snare, tightened to make it a pseudopedicle polyp, and then excised with PSD (converting a wide base lesion into a pseudopedicle polyp). Its advantage does: the injury is small, and the colon nursing liquid is suitable for pathological changes of all parts of the colon; no damage to the muscle layer, if the operation is correct, the perforation danger can be avoided; the small flat lesion can be completely removed at one time; the bleeding rate is low, and the bleeding can be basically prevented by matching with titanium clip suture; the cut specimen has small electric coagulation injury and is convenient for pathological observation. The disadvantages are: the operation difficulty is high; special equipment (injection needle and snare with hook) is needed; not suitable for larger lesions.
For larger flat lesions, large lateral developmental tumors (LST), EMR cannot be removed cleanly at one time, and injection fractionated mucosectomy (EPMR) is the best procedure, otherwise surgical intervention is required. However, for large lesions, the EPMR operation is difficult to operate, and requires higher skill of the operator.
Currently, Endoscopic Mucosal Resection (EMR) is a new treatment developed on the basis of polyp electrostomy and mucosal injection; the operation is that adrenaline or normal saline is injected under mucous membrane to lift the pathological tissue, so that the mucous membrane layer is separated from the muscular layer, and then high-frequency electrotome excision is carried out.
In actual operation, epinephrine or normal saline is injected under mucosa to lift the pathological tissues, so that the mucosa layer is separated from the muscular layer, and then the snare is used for electrified excision, wherein the specific process is shown in fig. 5 (positioning, injection, wiring, excision and collection of focus are sequentially performed). However, the current snare has no injection function, so that the operation needs to be repeated for many times, the excision operation can be carried out only by injecting adrenaline or normal saline into other injection instruments to lift the lesion tissue, and the operation is time-consuming and labor-consuming. In addition, due to the peristaltic property of the gastrointestinal tract, particularly in special parts such as sigmoid colon and the like, the endoscope is easy to slip and lose target lesions, so that snare excision cannot be performed immediately after the lesions are injected and lifted, and the difficulty and risk of the operation are increased.
