Description

Technical Field

[0001] The invention relates to the field of medical instruments, in particular to an instrument used for anal fistula hanging thread therapy. Background Art

[0002] Anal fistula, also known as anorectal fistula, is a granulomatous tube connecting the anal canal or rectum with the perianal skin. It mainly invades the anal canal and rarely involves the rectum, so it is often called anal fistula. The inner opening is mostly located near the dentate line, and the outer opening is located at the perianal skin. The entire fistula wall is composed of thickened fibrous tissue, covered with a layer of granulation tissue, and it does not heal for a long time.

[0003] The hanging thread therapy is suitable for high-positioned simple or complex anal fistulas. This method can avoid postoperative anal incontinence caused by the sphincter being broken and contracted at one time. It is widely used clinically and easy to operate. The surgical method is to insert a probe from the external opening under anesthesia, pass it through the internal opening along the fistula, tie a rubber band on the probe at the internal opening, and then lead the rubber band from the internal opening through the fistula to the external opening, cut the skin between the internal and external openings, and tighten the rubber band to ligate. The thread can be tightened again 3 to 5 days after surgery. Generally, the rubber band will fall off within 1 to 2 weeks after surgery, leaving an open wound that can gradually heal. If the rubber band does not fall off after two weeks, the tissue tied with the rubber band can be cut with scissors or tightened again.

[0004] When in use, the rubber band and the probe need to be tied and connected first, and then the probe is used to find the fistula. During the operation, the rubber band is likely to hinder the operation, and the rubber band will be placed in an open environment, which is not conducive to maintaining its cleanliness. Summary of the invention

[0005] The present invention aims at the technical problems existing in the prior art and provides an apparatus for anal fistula hanging thread therapy.

[0006] The technical solution of the present invention to solve the above technical problems is as follows:

[0015] Further defined, the first plugging portion includes two elastic hooks. One end of each of the two elastic hooks is fixedly connected to the end of the probe strip, and the other end is separated outward to form a V-shaped structure. A limiting convex block is arranged at one end of each of the two elastic hooks far away from the elastic wire.

[0016] The second plugging portion includes a clamping groove embedded in the tail end of the probe strip. Two through holes are formed in the side wall of the clamping groove. The two elastic hooks are inserted into the clamping groove, and the two limiting convex blocks are respectively embedded in the through holes.

[0017] Further defined, a balloon with a hollow structure is arranged between the elastic wire and the first plugging portion. A flushing tube parallel to the elastic wire is connected to the balloon. The flushing tube communicates with the balloon. One end of the flushing tube far away from the balloon is a closed structure, and a plurality of liquid-permeable holes are formed in the flushing tube.

[0018] Further defined, a spherical contact head is fixedly connected to the front end of the probe strip.

[0019] Further defined, a connecting block is further included. A first connecting hole and a second connecting hole are formed in the connecting block. One end of the flushing tube far away from the balloon is inserted into the first connecting hole.

[0020] One end of the elastic wire far away from the balloon passes through the second connecting hole. A check valve flap is arranged at one end of the second connecting hole where the elastic wire passes through, or the check valve flap is located in the second connecting hole.

[0021] A receiving groove for accommodating the balloon is further formed in the connecting block. A through groove for the elastic wire and the flushing tube to pass through is formed in the side wall of the connecting block, and the through groove extends to the bottom of the receiving groove.

[0022] Further defined, a pad cloth layer is wrapped outside the elastic wire.

[0023] The beneficial effects of the present invention are as follows:

[0024] The handle is formed into a cavity structure by the snap - fit of an upper cover body and a lower cover body. An installation groove is provided at the front end of the upper cover body, and a movable block is arranged in the installation groove. A support spring is arranged between the bottom of the movable block and the bottom of the installation groove, and the movable block can move in the installation groove by pressing to overcome the elastic force of the support spring.

[0025] In addition, since the first installation hole formed in the movable block and the second installation hole on the front end of the upper cover body are in a staggered position when the movable block is in the highest position. When installing the probe, first press the movable block downward to make the first installation hole and the second installation hole coaxially communicate. Then insert the tail end of the probe through the first installation hole and into the second installation hole. Then release the movable block, and the movable block is pushed upward under the action of the support spring. The tail end of the probe is clamped and fixed by the misalignment of the hole walls of the second installation hole and the first installation hole. The handle can be used as the operation and gripping part of the probe, improving the convenience of operation.

[0026] Furthermore, a cavity is provided at the front end of the lower cover body, and the elastic wire is placed in the cavity. The cavity communicates with the outside through a third installation hole. When in use, first connect the probe to the handle. After the probe probes the fistula by holding the handle, release the probe by pressing the movable block. Then hold the tail end of the probe and insert the tail end of the probe into the third installation hole, so that the second insertion part at the tail end of the probe is clamped and fixed with the first insertion part at the end of the elastic wire, and then pull out the elastic wire.

[0027] By connecting the elastic wire and the probe in a snap - fit manner, the operation can be facilitated. And by providing a cavity as the placement space for the elastic wire, the elastic wire can be in a relatively sealed environment, which can ensure the cleanliness of the elastic wire and prevent it from being contaminated.

The light - emitting element can be installed at the front end of the upper cover body, the front end of the lower cover body, or the snap - fit part of the front ends of the upper cover body and the lower cover body.

[0029] The first insertion part is a V - shaped structure composed of two elastic hooks, which is inserted into the card slot at the tail end of the probe. The limiting protrusions provided at the ends of the two elastic hooks cooperate with the through - holes on the inner wall of the card slot for snap - fit connection, which can effectively connect and fix the probe and the elastic wire. When separation is required, use scissors to cut and separate the first insertion part from the elastic wire, or squeeze the two limiting protrusions so that they retract into the card slot, then the probe and the elastic wire can be separated. The operation is simple and convenient, and the probe and the elastic wire can be quickly connected and quickly disassembled, effectively improving the operation convenience.

[0030] A balloon with a hollow structure is arranged between the first plugging part and the elastic wire, and a flushing tube is connected to the balloon. During operation, the flushing tube can enter the fistula together with the elastic wire. When it is necessary to flush and clean the inside of the fistula, the flushing liquid can be inhaled into a syringe, and the flushing liquid is pressed into the flushing tube by the balloon through the syringe and sprayed out from the liquid outlet hole to flush the fistula. By means of indwelling the flushing tube, it can effectively prevent the adverse effects on the wound healing of the fistula caused by the repeated insertion of the flushing device when flushing the fistula. Among them, the balloon can be made of elastic materials such as silica gel, which can play a positioning role and can also seal the puncture hole with its own elasticity after being punctured;

[0031] One end of the elastic wire is fixedly connected to the balloon and is fixed by being embedded in the accommodating groove through the through groove, and the other end passes through the second connection hole. The tightness of the elastic wire can be adjusted by pulling, which is convenient for operation;

[0032] The check valve flap arranged at the end of the second connection hole where the connection hole exits can fix the position of the elastic wire and prevent the elastic wire from retracting;
