Abstract
This utility model relates to cover cutting opening apparatus field, be specially the cover cutting opening apparatus obtaining Submucosal lesion tissue, this cover cutting opening apparatus is by elastic tape, drag wire, hyaline cap, needle-like cutter, needle-like cutter epitheca, mutually connected to form by suit buckle, this utility model is widely used in medical cover cutting opening apparatus, as: the cover cutting opening apparatus etc. obtaining Submucosal lesion tissue, the medical appliance shape that can solve the acquisition Submucosal lesion tissue produced both at home and abroad is single, time-consuming during use, effort, acquisition tissue mass is few, be unsuitable for little Submucosal lesion, shortcoming problem that positive rate is not high etc., the medical appliance of the acquisition Submucosal lesion tissue produced can be replaced completely both at home and abroad.
Description
Technical field
This utility model relates to cover cutting and opens technical field, is specially the cover cutting opening apparatus obtaining Submucosal lesion tissue
Background technology
At present, take the method for the direct biopsy tissue of biopsy forceps to carry out pathological diagnosis for the Submucosal lesion found in gastrointestinal endoscopy more.But under pathological changes is positioned at mucosa, its surface mucosa mostly is normal mucosa tissue, the pathological tissues needed for conventional bioptome is difficult to obtain.In recent years, have take apply biopsy forceps at a position repeatedly biopsy deep-cut method, but the pathological diagnosis positive rate of this method is not high.And take endoscopic ultrasound-guided fine-needle aspiration biopsy, technical requirement is high, somewhat expensive, acquisition tissue mass are few, it is not high to be unsuitable for little Submucosal lesion, positive rate, so be not suitable in clinical extensive popularization.
How to provide a kind of and effectively overcome the difficult problem obtaining Submucosal lesion tissue difficulty, the present inventor in routine duties, according to the organizational structure feature of human digestive organ, effectively be combined with modern medical equipment, for obtaining pathological tissues, reduce the variation of pathological tissues in acquisition process, distortion, degeneration, for treatment provides complete pathology foundation later, inventor finally successfully develops through repeatedly studying, and obtains the cover cutting opening apparatus of Submucosal lesion tissue.
Utility model content
This utility model object is to provide, obtain the cover cutting opening apparatus of Submucosal lesion tissue, the medical appliance shape solving domestic acquisition Submucosal lesion tissue is single, time-consuming during use, effort, obtain that tissue mass is few, to be unsuitable for little Submucosal lesion, positive rate not high, etc. shortcoming problem.
The technical solution of the utility model is:
Obtain the cover cutting opening apparatus of Submucosal lesion tissue by elastic tape, drag wire, hyaline cap, needle-like cutter, needle-like cutter epitheca, mutually connect to form by suit buckle the cover cutting opening apparatus obtaining Submucosal lesion tissue.
The beneficial effects of the utility model are:
1, the cover cutting opening apparatus obtaining Submucosal lesion tissue is safe and reliable.Prick fixing pathological changes and blocking blood flow by cover, avoid occurring when cutting hemorrhage, incision surface mucosa can fully expose Submucosal lesion tissue, ensures to obtain enough tissue mass, raising pathological diagnosis positive rate, simple to operate, safety.
2, the cover cutting opening apparatus practicality of Submucosal lesion tissue is obtained.This utility model, cover cutting opening apparatus can be sampled to the Submucosal lesion tissue of esophagus, Stomach duodenum and colon, sampling process is quick, sampling is abundant, and user can obtain high-quality tissue specimen for pathological diagnosis, and other medical appliance does not have this structure both at home and abroad.
3, the cover cutting opening apparatus operability of Submucosal lesion tissue is obtained.It is machining production line balance that this utility model overlaps cutting opening apparatus, and convenient operation person operates, and alleviates physical work, and cover cutting opening apparatus safely, reliably, conveniently.
In a word, this utility model is compared with the utensil of pathological tissues under the acquisition tissue adherence of producing both at home and abroad, have accuracy high, be applicable to scope under use, save acquisition time, acquisition pathological tissues is even, production process is short, the suitability is wide, safety and sanitation, cost is low, workable and be easy to the features such as processing and manufacturing, can replace the utensil of the acquisition Submucosal lesion tissue produced completely both at home and abroad.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In Fig. 1, hyaline cap 1; Elastic tape 2; Drag wire 3; Needle-like cutter 4; Needle-like cutter epitheca 5.
Detailed description of the invention
As shown in Figure 1, there is shown, the cover cutting opening apparatus of this utility model acquisition Submucosal lesion tissue is provided with hyaline cap 1; Elastic tape 2; Drag wire 3; Needle-like cutter 4; Needle-like cutter epitheca 5 forms, and its concrete structure is as follows: the cover cutting opening apparatus of this acquisition Submucosal lesion tissue by elastic tape, drag wire, hyaline cap, needle-like cutter, needle-like cutter epitheca, connects the obtained cover cutting opening apparatus obtaining Submucosal lesion tissue by suit buckle mutually.
Embodiment
Plastic, transparent cap (1) is installed on scope front end, plastic, transparent cap preloads elastic tape (2) and drag wire (3), after searching out Submucosal lesion, aim at pathological changes with plastic, transparent cap (1) front end, utilize vacuum suction pathological changes to be sucked in plastic, transparent cap (1).Pull drag wire (3) to discharge elastic tape (2), make elastic tape (2) ligation pathological changes root, make pathological changes form one and obviously swell and block its blood flow.Then needle-like cutter epitheca (5) is inserted in transendoscopic biopsy duct, after diseased region, stretch out needle-like cutter cutter silk (4) and cut lesion surface mucosa, expose submucous tissue, submucous tissue is got, for pathological diagnosis again with common biopsy forceps pincers.
Claims (1)
1. obtain the cover cutting opening apparatus of Submucosal lesion tissue, it is characterized in that: the cover cutting opening apparatus of this acquisition Submucosal lesion tissue is by elastic tape (2), drag wire (3), hyaline cap (1), needle-like cutter (4), needle-like cutter epitheca (5), connects to form by suit buckle the cover cutting opening apparatus obtaining Submucosal lesion tissue mutually.
