Description

A kind of rectum clamp

Technical field

The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of treatment congenital megacolon, haul out operation behind colectomy, the rectum, drag the rectum clamp apparatus of colon antetheca and the clamping of former rectum rear wall down.

Background technology

At present, treatment congenital megacolon (Duhamel) operation both at home and abroad, colon drags under behind the rectum, for guaranteeing the fusion between two intestinal, people have done a large amount of trials, from the linear type cutting closer that the various vascular forceps, metallic screw formula proctologic clamp binder and the present part large hospital that begin to use are being applied, above-mentioned medical apparatus and instruments has played certain positive role to patient's operative treatment.But it is significantly not enough that above-mentioned medical apparatus and instruments still exists in the process for the treatment of patient: the narrow easy formation gate syndrome of folder face, and apparatus weight causes patient's misery greatly, and use bothers and costs an arm and a leg.

Summary of the invention

In order to overcome existing metallic screw formula rectum clamp and linear type cutting closer, easily formation sluice gate syndrome, apparatus weight cause patient's misery greatly, use trouble and the expensive problem of price, the invention provides a kind of medical apparatus and instruments rectum clamp for the treatment of the rectum patient.This rectum clamp not only can be avoided the sluice gate syndrome, alleviate patient's misery, and easy to use, low-cost medical apparatus and instruments.

The technical solution adopted for the present invention to solve the technical problems is: a kind of rectum clamp, form by lower clamping bar, open type ellipse or circular rings, screw, screw rod, boosting-rod on the duckbill; Open type elliptical ring or annulus respectively with duckbill on lower clamping bar be connected as a single entity, the oval or ring circular rings of open type is provided with a screw, and a screw rod is installed in the screw, the tail end of screw rod connects boosting-rod; The opening part of described open type elliptical ring rectum clamp is provided with boss, and boss is provided with conical socket, and cone-shaped groove is used for the addendum cone location of pushing tow screw end head, turn screw rod firmly, lead-screw enters in the opening, and the duckbill clamping bar opens about making, operation when being convenient to perform the operation; The duckbill clamping bar of described rectum clamp vertically be provided with the long trough hole, the long trough hole is used for discharging the drift of operation.Be respectively equipped with the zigzag face on the face closing in opposite directions of two clamping bars up and down, the zigzag face is used for strengthening and clamps (dragging rectum front wall and former rectum rear wall down) intestinal wall, guarantees slowly necrosis of intestinal wall, makes then and melts coelosis between two intestinal, reaches requirements of operation.

The invention has the beneficial effects as follows, easy and simple to handle, because the tensile cone push rod design and installation of control is in elliptical ring afterbody screw, this clamper light weight, finish clamping after, remove tapered rod, only there is annulus to place outside the anus, overcome traditional metal clamp and when the turn of the screw, caused the clamper displacement, and use the pair damage that various vascular forceps clamping caused, avoid making after various traditional vascular forceps clamping pincers handle and traditional metal clamp afterbody to stay that anus is outer to cause suffering to the patient simultaneously.

The present invention is cheap, and the price of a rectum clamp has only 1/10 of import rectum cutting closer price at most, numerous patients is cured the disease afford to use.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is a rectum clamp A-A cutaway view.

Fig. 3 is the B-B cutaway view of Fig. 1.

Fig. 4 is that the C of Fig. 2 is to view.

Clamping bar on 1. duckbill among the figure, 2. duckbill lower clamping bar, 3. clamping gap, 4. annulus opening, 5. annulus thin-walled, 6. screw rod, 7. boosting-rod, 8. annulus, 9. addendum cone, 10. toothed surface, 11. long slot bores.

The specific embodiment

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, duckbill clamping bar (1), (2) are connected as a single entity with open circles ring body (8) and form the clamp of rectum clamp, thicken at the rear portion of rectum clamp annular circle body (afterbody), on thickening annulus wall, be provided with screw, screw rod (6) is installed in the screw, and the follower head of screw rod (6) is provided with boosting-rod (7); Vertical front portion of duckbill clamping bar (1), (2) is that arc is upturned, the back is straight shape, to adapt to the natural torsion of rectum, anterior top is a button-head, vertical centre of duckbill clamping bar (1), (2) is provided with long slot bore (11), this long slot bore is used for during rectum clamp is retained in anal orifice and rectal intestine, and intestinal contents is discharged to the anus direction.Duckbill clamping bar (1), (2) are to the cylindrical after the clamping being ellipse or circular, after last lower clamping bar is clipped together in opposite directions, form ellipse or circular space in the clamping bar cross section, last lower clamping bar is designed to the intensity that half elliptic or circular thin-walled have strengthened clamping bar, alleviate the weight of rectum clamp simultaneously, be convenient to operation technique.On the sandwich serface in opposite directions of duckbill clamping bar (1), (2), be provided with zigzag tiny tooth sandwich serface (10), when two clamping bars up and down in opposite directions after the clamping the little tooth of zigzag can to guarantee that clamping bar clamps and sting the back to intestinal wall closely stable.

Opening annulus (8) is designed to ellipse or round, the opening annulus from the afterbody thickening to annulus opening part thickness thinning progressively, make the annulus wall that certain elastic force be arranged, be convenient to thrust screw rod (6) item and open lower clamping bar, front portion and last lower clamping bar joint at opening annulus (8) are provided with annulus opening (4), back at opening (4) convexes to form boss, establish conical socket in the middle of the boss, conical socket and opening join and form annulus opening (4), if boss is in order to strengthen annulus opening part wall thickness intensity, in order to avoid the addendum cone (9) of front end leaves place's annulus wall destruction with mouth after the pushing tow screw rod application of force.The front end of ellipse or circular rings (8) up and down the thickness of annulus wall progressively letter is thin, make anterior formation of annulus have the elasticity arm of force, be used for that rectum clamp opens and return.Perform an operation when needing with this rectum clamp, precession pushing tow screw rod (6) firmly, addendum cone (9) backs down annulus opening (4) and enters in the opening, force the outside open while clamping bar in annulus thin-walled place (1), (2) outwards open, to drag colon antetheca and former rectum rear wall to be clamped together down, withdraw from pushing tow screw rod (6) then, make the addendum cone (9) of screw front end leave annulus opening (4), under the effect that rectum clamp makes a concerted effort to recover, duckbill clamping bar (1) and (2) closure will drag colon antetheca and rectum rear wall closely to clip together down up and down, make the intestinal wall in the sandwich serface slowly downright bad, two intestinal healing coelosis makes patients ' recovery then.

Available metal of the present invention and engineering plastics are made.
