Description
Technical Field
The utility model relates to a medical instrument, in particular to anal fistula resection device.
Background
Anal fistula is a short term for anorectal fistula and is a residual lesion caused by abscess rupture or incision drainage around the anorectum. Anal fistula is an abnormal conduit for the rectum to communicate with the skin around the anal canal and generally consists of three parts, namely a primary internal orifice, which is the focus of infection, and a secondary external orifice, most of which is in the anal sinus.
Surgery is the fundamental method for treating anal fistulas, and accurate management of the infected internal orifice is critical to the success of the surgery. The probe is an important tool for checking and treating anal fistula, and aims to clarify the trend, length, depth and relation of the fistula with anal sphincter, determine the position of the internal orifice, introduce a rubber band and the like. For high complexity anal fistulas, treatment may be by thread-hanging therapy.
The surgical treatment of the anal fistula needs to treat key problems of an internal orifice, a fistula tract, sphincters and the like, and epithelialization of a residual fistula tract is one of the reasons for recurrence of the anal fistula, so that how to completely cut the fistula tract in the surgery becomes one of the basic links of a plurality of anal fistula treatment technologies, however, completely cutting the fistula tract is not easy and has the risk of damaging the sphincters.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can carry out circumference excision and easy and simple to handle's anal fistula resection device.
The utility model provides an anal fistula excision device, which comprises a soft probe for exploring the fistula tract position, a puncture guide inserted into the fistula tract position, a circular cutting sleeve and a stopper which can be fixed on the puncture guide after being inserted; the circular cutting sleeve is provided with a hollow pipeline, and the puncture guide can be inserted into the hollow pipeline of the circular cutting sleeve.
Further, circular cutting sleeve includes stiff end and the sleeve end of being connected with the stiff end, the cavity pipeline runs through on stiff end and sleeve end.
Further, the fixed end and the sleeve end are both cylindrical.
Further, the outer diameter of the fixed end is larger than the outer diameter of the sleeve end.
Further, the stopper is fixed to one end of the puncture introducer while the puncture introducer is inserted into the fistula site, and the other end of the puncture introducer is inserted into the circular cutting sleeve.
The utility model discloses anal fistula resection device is equipped with circular cutting sleeve, can carry out controllable perimeteric resection to granulation and epithelial tissue in the fistula, reduces the incision diameter under the condition that does not harm anal sphincter, and is easy and simple to handle, helps the branch pipe to explore, can improve anal fistula's cure rate.
Drawings
The invention will be further described with reference to the following figures and examples:
FIG. 1 is a schematic structural view of a soft probe and a puncture guide of the anal fistula excision device of the invention;
fig. 2 and 3 are schematic structural views of the puncture guide, the circular cutting sleeve and the stop air of the anal fistula excision device.
Detailed Description
The utility model relates to an anal fistula resection device for excise anal fistula way, as shown in fig. 1 to 3, anal fistula resection device is including inserting puncture guide 10, the circular cutting sleeve 20 of fistula position, exploring the soft probe 30 of fistula way position and can fixing the stopper 40 on puncture guide 10. Wherein the circular cutting sleeve 20 is provided with a hollow tube 21 and the puncture guide 10 can be inserted into the hollow tube 21 of the circular cutting sleeve 20.
Wherein, circular cutting sleeve 20 includes stiff end 22 and the cover end 23 of being connected with stiff end 22, and cavity pipeline 21 runs through on stiff end 22 and cover end 23, and stiff end 22 and cover end 23 all are the cylinder type, and the external diameter of stiff end 22 is greater than the external diameter of cover end 23.
The circular cutting sleeve 20 allows for controlled circumferential resection of granulation and epithelial tissue within the fistula.
The utility model discloses anal fistula resection device is by experienced colon rectum surgeon's main knife, gets rid of all active inflammation and abscesses before the art, takes the lithotomy position under the general anesthesia, and all patients give cefuroxime sodium and metronidazole intravenous injection 30 minutes before the art, and anal inspection gets rid of lax string line, introduces the utility model discloses anal fistula resection device.
In use, the flexible probe 30 probes a fistula tract; after probing the position of the fistula, the puncture introducer 10 is inserted into the fistula and then the soft probe 30 is taken out; a stopper 40 is fastened to one end of the puncture introducer 10 inserted into the fistula; inserting the circular cutting sleeve 20 along the other end of the piercing guide 10 such that the other end of the piercing guide 10 is inserted within the hollow conduit 21 of the circular cutting sleeve 20; rotationally advancing the circular cutting sleeve 20 against the stop 40 to resect the fistula tract; after cutting the fistula tract, the stopper 40 is removed from the puncture introducer 10 and the circular cutting sleeve 20 is removed with the puncture introducer 10.
Wherein the other end of the penetration guide 10 is inserted into the hollow conduit 21 of the circular cutting sleeve 20 from the sleeve end 23.
The circular cutting sleeve 20 is moved over the puncture introducer 10 by the fixed end 22 in the direction of the actuator 40, which cuts the fistula tract during the movement.
The utility model discloses anal fistula resection device is equipped with circular cutting sleeve, can carry out controllable perimeteric resection to granulation and epithelial tissue in the fistula, reduces the incision diameter under the condition that does not harm anal sphincter, and is easy and simple to handle, helps the branch pipe to explore, can improve anal fistula's cure rate.
