Gun type hemorrhoid operation anastomat
Technical field
The present invention relates to a kind of surgical medical equipment, particularly a kind of gun type hemorrhoid operation anastomat.
Background technology
Hemorrhoid are a kind of frequently-occurring diseases, and traditional hemorrhoid suction and ligature device can only be treated early stage single internal hemorrhoid, is not suitable for ring-type hemorrhoid and prolapse of rectal mucosa; The tubular hemorrhoid anastomat of another kind of treatment ring-type hemorrhoid owes convenient but use.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of excision and identical internal hemorrhoid of being used for, the gun type hemorrhoid operation anastomat of mixed hemorrhoid, ring-type hemorrhoid and prolapse of rectal mucosa.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of gun type hemorrhoid operation anastomat, its shell and the back handle composition rifle shell that is connected as a single entity with its rear end, the external screw thread socket of the female thread of shell and magazine is provided with cylindrical shape cutting knife and anastomosis staple in the magazine; The sleeve that in shell, is slidingly installed, telescopic small end withstands the cylindrical shape cutting knife tail end of magazine; The front end of center-pole is connected as a single entity with the nail seat, and the center-pole cover is inserted in magazine and the sleeve; Be provided with spring between telescopic major part and the shell, be positioned at the adjusting nut in the shell follower head outside and the end of thread socket of center-pole; It is hinged by bearing pin and back handle that the middle part is provided with the front hand grip that refers to circle, and the cam of front hand grip termination withstands telescopic major part; Be provided with rotating cylindrical safety plug in the circular hole of back handle, its handle is arranged on the outside of back handle, is provided with the semicircle groove interlock of cylindrical safety plug and cam and the adjusting nut of breach P.
The invention has the beneficial effects as follows:
1. the present invention is similar to pistol, gripping and easy to operate.
2. can in the excision hemorrhoid, otch be coincide, operation is quick, coincide firmly, hemostasis rapidly, wound not bitterly.
3. the front end of center-pole and firm being connected as a single entity of nail seat, the location of avoiding split type center-pole to cause is inaccurate, dislocation, otch local hemorrhage coincide; Split type center-pole is difficult to clean with the slit that is connected of nail seat, and easily store blood dirt causes infecting; And its connecting portion is yielding, need often return factory-run school standard, repairing.
4. adjusting nut is a monoblock type, can regulate magazine and the relative position of following closely seat more accurately than split type adjusting nut, to reach best match result.
5. the magazine integral body of band cylindrical shape cutting knife and anastomosis staple is inserted in center-pole, and is convenient and reliable.
6. the handle of cylindrical safety plug is arranged on the outside of back handle, and is more convenient reliable.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples
Embodiment is shown in Fig. 1-7: a kind of gun type hemorrhoid operation anastomat, its shell 4 and the back handle 11 composition rifle shells that are connected as a single entity with its rear end, the external screw thread socket of the female thread of shell 4 and magazine 2, be provided with cylindrical shape cutting knife and anastomosis staple in the magazine 2, the sleeve 3 that is slidingly installed in shell 4, the small end of sleeve 3 withstands the cylindrical shape cutting knife tail end of magazine 2.The front end of center-pole 1 is connected as a single entity with nail seat 13, and center-pole 1 cover is inserted in magazine 2 and the sleeve 3; Be provided with spring 5 between the major part of sleeve 3 and the shell 4, be positioned at the end of thread socket of adjusting nut 6 with the center-pole 1 in the shell 4 follower heads outside.It is hinged by bearing pin 9 and back handle 11 that the middle part is provided with the front hand grip 10 that refers to circle 12, and the cam 8 of front hand grip 10 terminations withstands the major part of sleeve 3; Be provided with rotating cylindrical safety plug 7 in the circular hole of back handle 11, its handle is arranged on the outside of back handle 11, is provided with the semicircle groove interlock of cylindrical safety plug 7 with cam 8 and the adjusting nut 6 of breach P.
The breach P of shown in Figure 1 is cylindrical safety plug backwards, pin 7 lockings that all are insured of the traversing and cam 8 of adjusting nut 6, adjusting nut 6 can not be walked crosswise mobile, but rotatable.Turn adjusting nut 6 can promote center-pole 1, regulates the spacing of nail seat 13 and magazine 2.Slewing circle cylindricality safety plug 7 is to the mounting or dismounting center-pole shown in Figure 2 and the state of adjusting nut, the breach P of safety plug up, 7 locking cams 8 of safety plug; Adjusting nut 6 was both rotatable, can laterally move again, and rotation adjusting nut 6 can withdraw from adjusting nut 6 from shell 4.
During operation, the breach P of the safety plug of gun type hemorrhoid operation anastomat backwards, as shown in Figure 1, the traversing and cam 8 of adjusting nut 6 lock that all is insured is fixed.Operative doctor grips back handle 11, and finger hooks the finger circle 12 of front hand grip 10, will follow closely seat 13 and push in patient's anus, near affected area.Turn adjusting nut 6 promotes a center-pole 1 and the nail seat 13 accurate positions to focus, slewing circle cylindricality safety plug 7 to the breach P of safety plug shown in Figure 3 down, a safety plug lock adjustment nut traversing, cam is in the percussion state for the treatment of; Pull front hand grip 10, promote the cylindrical shape cutting knife and the anastomosis staple of sleeve 3 and magazine 2 forward, in the excision hemorrhoid, depress anastomosis staple otch is coincide.Operation is quick, coincide firmly, hemostasis rapidly, wound not bitterly.After the percussion, unclamp front hand grip 10, under the promotion of spring 5, sleeve 3 and front hand grip 10 return to original position.
