A magnetically guidable medical device for use within the large intestine of a human body. A magnetically guidable guide wire is introduced into the rectum of a body of a patient and maneuvered through the colon under the influence of a controlled magnetic field to a desired location within the body of the patient. An external magnetic field applying means applies an external magnetic field effective to guide the magnetically guidable member within the body of the patient. A colonoscope is advanced over the guide wire so that the advancement and placement of the colonoscope is aided by the magnetically guided guide wire. Either or both the magnetically guidable guide wire and the colonoscope can be viewed using a fluoroscope to assist in positioning it within the body of the patient.

The invention discloses an iliofemoral deep venous moniliform eccentric sacculus thrombolytic thrombolysis thrombectomy catheter and a using method of the iliofemoral deep venous thrombosis moniliform eccentric sacculus thrombolysis thrombectomy catheter. The tail end of the catheter is composed of two openings, wherein one is a sacculus catheter opening, and the other one is called a Y valve connector, is a common entrance of a guide wire for guiding and a thrombolysis catheter, and is used by being connected with a Y valve. A catheter end is a two-cavity catheter composed of two catheters in a fusing mode, wherein the two catheters are mutually independent in function, one cavity serves as a sacculus catheter passage, and the other cavity serves as a guide wire and thrombolysis catheter passage. A catheter working part is composed of moniliform eccentric sacculus and a corresponding crack thrombectomy catheter on the other side. Catheter cavities are made of a +PTEE hydrophilic coating. Each part of the sacculus and each part of thrombolysis (with the length of 10-20cm) can work respectively or simultaneously. Sacculus (with the diameter of 5-20mm) squeezes thrombectomy. Thrombectomy medicine thrombolysis can be simultaneously filled in the crack catheter on the other side. The crack catheter on the other side can rotate so as to improve thrombolysis thrombectomy effect.

A first embodiment of the invention involves an improved cut-in box to facilitate connection to at least one cable behind a wall. A second embodiment of the invention involves a cut-in box mounting bracket to clamp a cut-in box to a wall opening. A third embodiment of the invention involves an anti-short mechanism for an electrical cut-in box.

The invention relates to an unreeling device special for embedded silk threads, which consists of a vertical upright post, a main leading silk connecting piece, two auxiliary leading silk connecting pieces, a horizontal transversely-arranged hack lever, a horizontal longitudinally-arranged hack lever and a base, wherein the middle of the main leading silk connecting piece is provided with a horizontal through hole and a vertical through hole which are not communicated mutually; the lower end of the vertical upright post is provided with the base which is fixed with the ground, while the upper end passes through the vertical through hole in the middle of the main leading silk connecting piece and is fixed through a jack screw on the lateral surface; the horizontal transversely-arranged hack lever passed through the horizontal through hole of the main leading silk connecting piece; the main leading silk connecting piece is also provided with a threaded hole which is vertical and communicated with the horizontal through hole, and the horizontal longitudinally-arranged hack lever of which both ends are provided with threads is connected with the threaded hole; the middles of the two auxiliary leading connecting pieces are provided with T-shaped through holes; the two auxiliary leading connecting pieces are arranged at two ends of the horizontal hack levers; a three-way hole comprises one threaded hole; and the horizontal longitudinally-arranged hack lever of which both ends are provided with threads is connected with the auxiliary leading connecting pieces through the threads. The unreeling device has the advantages of simple integral structure, convenient operation and use, good stability and high reliability.

The present invention relates to a stent for protecting a branch blood vessel at a branch-point lesion. The stent is inserted into and widened in a main blood vessel having the branch blood vessel extending in a slant from the branch-point lesion, thereby simultaneously expanding the main blood vessel and providing a smooth flow of blood towards the branch blood vessel. As a result, it is possible to simultaneously expand the main blood vessel and to sufficiently secure a passage from the main blood vessel towards the branch blood vessel. As such, the flow of blood is kept smooth. Further, after the stent is inserted into the main blood vessel, another stent, a guide wire, and related tools and catheter can be inserted in the direction of the branch blood vessel in a more accurate manner.

The invention provides a scalpel for a cardiac apex incision, which belongs to the technical field of medical instruments. The scalpel comprises a scalpel handle provided with a communicated guide cavity, and a cutter head connected to the end of the cutter handle and provided with a through hole communicated with the guide cavity in the center of the cutter head; four blades surrounding the through hole are arranged at the end, deviating from the cutter handle, of the cutter head, the projections of the four blades in the radial direction of the cutter handle are distributed in a cross shape,and the blades face the direction deviating from the cutter handle and incline inwards. According to the scalpel, a guide wire is inserted into a designated position through the apex cordis before across incision of the apex cordis, and the guide wire plays a role in guiding; the guide wire passes through the guide wire cavity, so that the scalpel is inserted into the cardiac apex along the direction of the guide wire, and the size of the cross incision is controlled through the insertion depth of the scalpel; according to the four blades on the scalpel, the cross incision of the apex of theheart can be completed at a time, and the shape of the cross incision is standard.
