  • Patent number: 6743242
    Abstract: A dual-use suturing device for suturing a wound induced from a celioscope surgery is formed by a needle positioning seat, an auxiliary positioning device, and an upper cover buckled to the needle positioning seat. The positioning pieces at the top of the auxiliary positioning device are buckled to the embedding groove at a lower end of the needle positioning seat. The guide holes of the needle positioning seat have a tapered inner surface. Hollowed portions of the guide trenches provide clamping spaces at two sides of the auxiliary positioning device. Then two clean auxiliary positioning devices are used to clamp the wire needle and hooked needle so that the hand of the doctor can pinch the needles. The non-hollowed portions at the upper side of the guide trenches of the auxiliary positioning device are exactly formed as resisting portions for resisting against the needles.

  • Patent number: 6689088
    Abstract: An irrigator used in a celioscope surgery comprises a main casing, a water pumping stud and a water control stud which are engaged with the main casing. An interior of the main casing has a pumping opening and a suction opening, and a water outlet channel and a pumping flow channel which are vertical to the pumping opening and suction opening. Thereby, the water outlet channel and pumping flow channel are at an upper portion of the main casing. Thereby, dirty water accumulated in the affected part can be pumped out from a water outlet tube through the pumping flow channel. Since the water is pumped out along a straight way, it is prevented that dirty water is left in some bending portions. Therefore, dirty water can be pumped out completely. Furthermore, users may hold it by any hand conveniently.

  • Patent number: 6682538
    Abstract: An umbilical cord cutter retainer comprises a main spanner, a force applying spanner pivotally installed to the main spanner, and a cutting structure inserted in the main spanner. A distal end of the main spanner has an inserting groove for being inserted by a cutting structure. Two front lateral sides of the main spanner have respective umbilical cord clips which have different colors and are detachable. Normally, the umbilical cord clips supports the force applying spanner so as to be expanded from the main spanner. A knife is inserted into the force applying spanner. A knife can be exactly inserted into a place between the two umbilical cord clips for cutting the umbilical cord between the two umbilical cord clips. Moreover, two ends of the inserting groove of the main spanner have guide grooves. Thereby, the cutting structure can be guided into the inserting groove of the main spanner easily.
