Abstract

The utility model relates to an alimentary canal early cancer endoscopic mucosa cutting instrument, which is especially suitable for the cutting of cancer focus or the cancer front focus which is restricted to mucous layers. The utility model is composed of a sleeve cutting cap (1) which is made of plastic and a connecting sleeve (2) which is made from silica gel. The cancer focus or the cancer front focus which is restricted to the mucous layers can be attracted to a mucosa cutting instrument which is arranged at the end of an endoscope by the negative pressure attraction action of endoscope forceps channels, and the focus can be looped by a snare under direct vision and can be cut by switching on power, so the purpose of treatment can be achieved. The utility model has the advantages of convenient operation, integrated specimen cutting, high safety, low cost, small patient pain and few spending, and can implement early cancer cutting in a few minutes under the conditions of no anaesthesia and not opening chest and abdomen.

Description

Digestive tract is cancer endoscopic mucosal resection device early

This utility model relates to a kind of digestive tract cancer endoscopic mucosal resection device early.The cancer of its particularly suitable limitation mucous layer or the excision of precancerosis kitchen range are used.

At present, the method that is used to excise the early cancer has the scope laser method, methods such as endoscopic micro-wave method and the excision of scope high-frequency electrical, but all degree different exist certain drawback.

The purpose of this utility model is that scope is treated in a kind of two pincers road easy to use, that replace costliness of design, being equipped with the plain edition scope can use, and can prevent to excise dark, can estimate the orientation of excision focus size and scope end again, the excision specimen is complete, safe and reliable, with low cost, patient's misery is little, cost is few, situation about need not anaesthetize can be finished carcinectomy early in following a few minutes, when getting final product free movable, feed, safe and effective.Can be widely used in the early stage esophageal carcinoma, carcinoma of gastric cardia and gastric cancer and precancer focus the mucosa resection device of direct view under endoscope.

This utility model is achieved in that it is that cut medicated cap 1. be that 2. the adapter sleeve of silica gel is formed with material for the cover of plastics by material.By means of the vacuum suction effect of endoscopic forceps channel, cancer or the precancerosis kitchen range that is confined to mucous layer is attracted in the mucosa resection device that is contained in the mirror end, direct-view ties focus with the snare cover down, energising excision again.To reach therapeutic purposes.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the ramp structure sketch map of this utility model embodiment.

Fig. 3 is the ellipsoid structural representation of this utility model embodiment.

In Fig. 1, cover is cut medicated cap outer wall 1. and one attached pipe is arranged 3., groove 4., gauge point 5., chase 7., 6. cover is cut medicated cap inwall 1. has a packet size line, 8. cover is cut medicated cap end openinginwall end 10. has inwardly protruded annular inner convex rib, 9. adapter sleeve 2. end opening inwall has convex tendon.It is plastics that cover is cut medicated cap material 1., cylindrical, the internal diameter size of last hypomere is unequal, 3. the attached pipe of its outer wall cuts medicated cap with cover is one, its objective is the effect of playing fixed trap device trocar sheath, the snare silk is freely stretched, and to adjust snare silk correct position when performing the operation, 3. this attached pipe has replaced the purposes of two pincers road mirror of treatment usefulness.4. groove is the semicircular ring groove, and its effect is the ring for fixing mantle fiber, and when gastroscope aiming focus, the vacuum suction focus is to the mucosa resection device, and release snare silk braid is lived mucosal tissue and tightened up, energising, and high-frequency electrical is excised it.5. gauge point is a round dot and scribbles color, is positioned at cover and cuts medicated cap end opening upper outer wall place 10., and purpose is the orientation of labelling scope, is convenient to accurately locate and execute art.7. chase is positioned at cover and cuts medicated cap top 1., purpose make cover cut medicated cap 1. adapter sleeve 2. socket be one.9. 7. chase match with convex tendon.8. cover is cut medicated cap end openinginwall end 10. has an inwardly protruded annular inner convex rib, and purpose is that the embedding that prevents the flesh layer causes mistake to be cut, to guarantee the depth desired-tela submucosa of carcinectomy early.6. cover is cut medicated cap inwall 1. has a packet size line, can predict the scope of resection organization when operation under the direct-view, and adapter sleeve material 2. is a silica gel, is cylindric.

As shown in Figure 2, cover is cut medicated cap cover 1. cut the medicated cap end opening 10. is an inclined-plane.Its objective is to being adapted to esophagus, the physiology and appearance feature of cardia and body of stomach rear wall, its cover is cut medicated cap end opening inclined-plane 10. and can be close to just and buckle and kiss in affected area.Vacuum suction is in the mucosa resection device, and energising is excised.

As shown in Figure 3, cover is cut medicated cap cover 1. and is cut the medicated cap end opening 10. for elliptical shape, and purpose is for being adapted to the attraction excision that is shaped as the strip focus of focus.

The cover of this utility model Fig. 2, mucosa resection device shown in Figure 3 is cut medicated cap cover 1. and is cut the medicated cap end opening and 10. be the inclined-plane, ellipse, and its operation principle that attracts excision is identical with the operation principle of mucosa resection device shown in Figure 1.

The utlity model has easy to usely, Operated Specimens is complete, and is safe and reliable, cost Cheap, patient's misery is little, and cost is few, and need not anaesthetize does not need to open chest and open in the abdomen situation Can finish the advantages such as early carcinectomy in a few minutes.

Claims (3)

1, a kind of digestive tract early cancer endoscopic mucosal resection device it is characterized in that it by material be the cover of plastics cut medicated cap 1. be that 2. the silica gel adapter sleeve is formed with material, 9. 7. chase match with convex tendon, make cover cut medicated cap 1. with adapter sleeve 2. socket be one.

2, digestive tract according to claim 1 cancer endoscopic mucosal resection device early, it is characterized in that overlapping cut medicated cap outer wall 1. have an attached pipe 3., groove 4., gauge point 5., chase 7..

3, digestive tract according to claim 1 cancer endoscopic mucosal resection device early, its feature also are to overlap to be cut medicated cap inwall 1. and one packet size line is arranged 6., and 8. cover is cut medicated cap end opening inwall end 10. has an inwardly protruded annular inner convex rib.
