Abstract

The utility model relates to a ring positioning device for elastic ring ligating in the esophagus and gastric-chamber. The utility model is suitable for the oesophagus and stomach anastomoses operation in particular after the oesophagus cancer and the cardiac cancer are ablated. The utility model is composed of a device body, a handle, a ring pushing mechanism and a pipe positioning mechanism, and the pipe positioning mechanism and the ring pushing mechanism work simultaneously. When the utility model is used, the suture material is not left at the position of the stoma after the oesophagus and the stomach anastomoses operations, and the stoma is tight; therefore, the utility model is favorable to prevent the stoma fistula and the stoma stenosis from being caused. The utility model has the advantages of easy operation, easy manipulation and time saving.

Description

Setting-ring instrument for elastic loop-tie-up in the esophagogastric cavity

This utility model relates to elastic force loop-tie-up setting-ring instrument in a kind of esophagogastric cavity.Be specially adapted to the anastomose esophagus stomach operation after the excision of the esophageal carcinoma, carcinoma of gastric cardia.

At present, in implementing the esophageal carcinoma, carcinoma of gastric cardia excision back anastomose esophagus stomach technology, commonly used is that manual silk thread coincide and anastomat silver nail or tantalum nail coincide.These two kinds of anastomose esophagus stomach methods are all left over various suture material at the anastomotic stoma place, and this foreign body stimulates can become one of major reason of main complications fistula of operative incision, and operation is all complicated, is difficult for grasping.

The purpose of this utility model provides a kind of novel anastomose esophagus stomach operating theater instruments, uses the woodenware tool not leave over suture material at the anastomotic stoma place, and anastomotic stoma is coincide tight, thereby helps preventing the generation of fistula of operative incision and anastomotic stricture.

This utility model is achieved in that

It by body, handle, throw-out collar mechanism, put pipe (stay pipe) mechanism and form, put pipe and work asynchronously with throw-out collar.

Using this apparatus to carry out the ultimate principle that elastic force ring is pricked in the esophagogastric cavity is that esophageal wall and coat of the stomach are pricked on the intracavity stay pipe (referring to Fig. 2) with the latex ring.Because the elastic force effect of latex ring makes esophageal wall closely paste mutually with coat of the stomach, therefore prick the position anastomotic stoma and heal gradually like this at ring.Prick below the position owing to degeneration, necrosis take place ischemia at ring.The latex ring has been attached on the stay pipe after healing is finished, because action of gravity and esophagus, gastric peristalsis make stay pipe and slough drop to gastric by anastomotic position thereupon, excretes with stool at last.

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 utilizes esophageal wall and coat of the stomach after this qixieshu to prick sketch map on the intracavity stay pipe with the latex ring.

Fig. 3 is the setting-ring instrument operation chart.

In Fig. 1, the body of this setting-ring instrument is made up of device body 24, device head 9, and device is as tubular, and there is fixed handle its rear end.The front end of device head 9 is the ladder tubulose, and the rear end is a conical pipe, and conical pipe one end connects with device body 24.Present embodiment is that device head 9 is installed back spot welding, polishing with device body 24.

The throw-out collar mechanism of setting-ring instrument is made up of throw-out collar 5, ejector sleeve 10, back-moving spring 12, slide block 13, flexible handle 21, bumper bar 20, spring leaf 18.Slide block 13, back-moving spring 12, ejector sleeve 10 are contained in the body intracavity, thread connection is used with slide block 13 in ejector sleeve 10 cover upper reset springs 12 backs, throw-out collar 5 is enclosed within the ladder tube outside of device head 9, and it connects with ejector sleeve 10 by screw 8, and screw 8 can slide in the slotted eye of device head 9.Flexible handle 21 is fixed on the device body 24 by branchia shaft screw 22, and the plush copper of flexible handle 21 upper ends can drive slide block 13 and move.Spring leaf 18 and bumper bar 20 are fixed on the fixed handle by screw 19 and bearing pin 14 respectively, when bumper bar 20 is positioned at safety position, and locking flexible handle 21.

It put pipe (stay pipe) mechanism by fixed bar 11, stay pipe is laid head and is formed, stay pipe is laid head and is made up of sleeve 28, X-shaped support 29, half-cylindrical fixed block 4, spring 6.Leaded 1 of sleeve 28 front end, rear end connect with fixed bar 11 usefulness screws 7.X-shaped support 29 and half-cylindrical fixed block 4 are fixed in the sleeve 28 by bearing pin 3, and the solid pipe button 2 of X-shaped support front end is inserted in the inner groove of stay pipe by the hole of sleeve 28.The rear end of X-shaped support is supported by spring 6, and has contact to expose outside telescopic hole.When ejector sleeve 10 travels forward, can press the contact of X-shaped support, and compression spring 6 makes the stay pipe inner groove deviate from the solid pipe button 2 of X-shaped support, thereby reach throw-out collar and put stay pipe synchronous working.Fixed bar 11 rear ends connect with adjusting nut 16, and device body 24 back seats are equipped with hollow nut 15.Be with ring washer 17 on the adjusting nut 16 being in, skid off backward to prevent adjusting nut near the left side of hollow nut 15.At the fixed bar postmedian one tangent plane is arranged, have a positioning block 23 to match in the left side of slide block 13, rotate to prevent fixed bar with above-mentioned tangent plane.

Can load onto collar awl 27 at device head 9 front ends of setting-ring instrument, it is shaped as the umbrella taper, and several (4-6) guide grooves are arranged on the male cone (strobilus masculinus).The external diameter of collar awl and the internal diameter of device head 9 are for movingly.The latex ring can be used the conical surface guider head 9 front end places of ring pawl along collar awl, put the latex ring after, again at throw-out collar 5 front ends money upper jacket 25.Collar awl can take off the latex ring after first-class.

This implement body parts are made by the 1Cr13 rustless steel.Stay pipe is by the nylon 1010 manufacturing, and the latex ring is made by the medical infusion latex tubing.

Below in conjunction with Fig. 3 the using method of this apparatus is made brief description:

After the esophageal neoplasm excision, with silk thread stomach tube 31 and lead riser 1 are coupled together, earlier the fixed bar 11 that stay pipe is housed is pushed in the esophagus 32 again, with the lotus colo(u)r streak esophagus is tied on the fixed bar, make the stay pipe lower edge just on this line.On stomach 33, wear an aperture, make the tail end of fixed bar enter gastral cavity, and stretch out from cardia 34 broken ends of fractured bone through the aperture of stomach.Carrying stomach again makes it near the esophagus broken ends of fractured bone.And then stretch into setting-ring instrument main body 35(except that fixed bar) from the cardia broken ends of fractured bone of stomach, on push away the setting-ring instrument main body, make it near the esophagus broken ends of fractured bone, rotate adjusting nut 16 this moment, make fixed bar to giving allocation (being side opening 30 centers of fixed bar tail end) to adjusting nut 16, put intra-annular flexible handle with holding this moment, just the latex ring can be placed anastomose esophagus stomach position (see figure 2).33 be stomach in 2 among the figure, 36 is the latex ring among Fig. 3.

The utility model has the advantages that using the woodenware tool to do the anastomose esophagus stomach postoperative does not leave over suture material at the previous anastomotic place, previous anastomotic is tight, thereby is conducive to prevent the generation of identical fistula and anastomotic stricture. Use simultaneously the woodenware tool easy and simple to handle, be easy to grasp, save time.
