Abstract

The utility model relates to a canalis cervices uteri inner wall cutter for gynecologic operations. The utility model is characterized in that an electric gear is arranged on a tail rod of an annular cutting knife; the front end of the annular cutting knife and a guide rod are provided with an inner shuttle and an outer shuttle which are used for fixing the inner and the outer openings of cervices, and a set of electric control systems. The cutter has the advantages of convenient and fast operation, smooth, even and complete incision, and high safety.

Description

Automatically controlled cervical canal inwall sickle

This utility model belongs to gynecological's medical surgical instrument, is to be used for time ring-type sickle of full palace cutting operation.

China Huangshi Hospital of Yegang Group Corp. had once proposed a kind of " electronic cervix uteri inwall girdling device " on March 9th, 95 to Patent Office of the People's Republic of China, this girdling device is mainly by the foot piece that is connected as a single entity with machine shaft, the ring-type cutter hub, guide rod, in, formations such as outside fix pin, though avoided in time full palace excision in the past entirely finishing the deficiency of operation preferably with patient's experience and operation skill, but clinical practice in the recent period proves, its structural design remains in following defective: the one, and guide rod is fixed on the cutting knife center, advance to the abdominal cavity direction with cutting knife rotation and with cutting operation, in art if grasp the bad anxiety that damage internal organs in the abdominal cavity of entering are arranged; The 2nd, after cutting finished, owing to the rotation of motor inertia, the patient can not stop cutting knife to continue action immediately, and at this moment, cutting knife cuts the smear metal that is produced and falls into intraperitoneal on plate washer, made the uncomfortable or generation complication of patient's postoperative.

For addressing the above problem, this utility model will provide a kind of safer reliable automatically controlled electronics cervical canal inwall sickle of operation that makes.

Concrete scheme of the present utility model is: do following improvement on the basis of " electronic cervix uteri inwall girdling device ": (1) is fixed in outside fix pin center with the guide rod of circular cutter, and insert in the tubulose cutter bar, (2) increase by a cover electric-control system, this system is furnished with display lamp, is fixed on the motor one end housing body and by electric-control system and instructs its miniature electricity of folding in rotating shaft to stop relay etc.

This utility model is after as above improving, the one, advance when making cervical canal inwall ring cutting to the abdominal cavity direction when cutting knife in the operation process, guide rod is actual to be to extend back, and has got rid of the possibility that guide rod enters abdominal cavity damage internal organs fully, has increased patient's safety in the operation; The 2nd, the electric-control system that increases, after cutting was finished cutting knife and metal derby on the plate washer is contacted, the conducting alternator indicator rose bright, cuts off the electricity supply simultaneously, stops cutting action, and the electricity clamping motor rotating shaft immediately of stopping is rotated with the cut off the electricity supply inertia of rear motor of prevention.Avoid cutting knife to continue to cut on plate washer producing smear metal falling into intraperitoneal.Reduce the generation that patient's postoperative does not accommodate complication.

Below in conjunction with drawings and Examples this utility model is described in further detail.

Fig. 1 is a cutaway view of the present utility model;

Fig. 2 is an electric-control system electrical principle block diagram among Fig. 1;

Fig. 3 is an electric-control system circuit diagram among Fig. 1.

Circular cutter is by annular cutting knife body 1, tubulose cutter bar 4, foot piece 5 be fixed on outside fix pin 2 centers and the guide posts 3 that insert in the cutter bar 4 are formed among Fig. 1, foot piece 5 is by motor-driven and drive the cutting knife rotation, front end at circular cutter is provided with plate washer 8, interior location needle stand 10 and interior position pin 7, stop screw 9, on plate washer 8, embed metal derby 11, be fixed with a pull hook 6, on metal derby 11, be connected to as shown in Figure 2 an electric-control system in its outside.

Fig. 3 illustrates the electric-control system circuit diagram.By transformator, diode D ₁-D ₄, C ₁, C ₂, silicon voltage regulator diode D ₂Rectifying and wave-filtering and voltage-stabilized power supply circuit that three terminal regulator W etc. form, provide 12-24V regulated power supply, when cutting is finished, when the metallic plate 11 that embeds on cutting knife and the plate washer contacts, be equivalent to K switch conducting among Fig. 3, meanwhile, light emitting diode D rises bright, and relay J is carried out outage, the electricity RL clamping motor rotating shaft of stopping stops cutting knife to continue rotation.

When using this utility model operation, at first guide post is inserted in patient's cervical canal, to keep the positive meta in cervix uteri place, and the guiding positioning needle is not thrust the cervix uteri collar extension on the bias, then interior positioning needle is packed into from the cervix uteri internal orifice, be retained the length of cervix uteri according to different cases, screw in guide post, make in the cervix uteri with stop screw, the outside fix pin combines as a whole, finger entangles pull hook, the thrust of ventrad is started electric device rotating ring cutting knife when rotating to overcome motor, when cutting is finished cutting knife and contacted with plate washer, the conducting electric current, display lamp rises bright, relay, electricity is stopped and is overcome the rotation of cutting knife inertia rapidly, and operation is finished.

The clinical use of this utility model proves, convenient except performing the operation, otch is smooth, even, complete, also increased patient's safety widely, effect is very satisfactory.

Claims

The cervical canal inwall sickle that uses in a kind of gynecilogical operation, it comprises: annular cutter hub (1), by motor-driven and drive the foot piece (4) of cutter hub rotation, when keeping operation the positive meta in cervix uteri place guide rod (3) and make cervix uteri inside and outside mouthful of fixing the be interior positioning needle (7) of one and outside fix pin (2) in parallel, it is characterized in that: guide rod (3) is fixed in the center of outside fix pin (2) and inserts in the tubulose cutter bar (4), and set electric-control system is stopped etc. by the regulated power supply that 12-24V can be provided, display lamp, relay, electricity and formed.
