Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in figures 1 and 2, the utility model discloses an adjustable vagina expanding instrument for gynecological operation, which comprises a handle 9, wherein the handle 9 is wholly curved so as to be convenient for the operation of doctors. A cylindrical shell 3 is installed at one end of a handle 9, a motor 7 is installed inside the shell 3, an output shaft of the motor 7 is coaxially connected with a lead screw 5, the lead screw 5 is rotatably connected with the shell 3, and a pushing seat 6 is in threaded connection with the lead screw 5; the pushing seat 6 is connected with the shell 3 in a sliding mode along the rotation axis of the lead screw 5, and the pushing seat 6 can be driven to slide in a reciprocating mode along the axial direction of the lead screw 5 by rotating the lead screw 5.
The end part of the shell 3 far away from the handle 9 is provided with a notch, the shell 3 is hinged with two duckbilled forceps clamps 1, and the two forceps clamps 1 are symmetrically arranged by the rotation central line of the screw rod 5. The provision of the gap may be such that the housing 3 does not interfere with the opening of the jaws 1. The forceps holder 1 comprises a forceps tail 1c connected with the shell 3, a forceps head 1a far away from the shell 3 and a forceps body 1b connecting the forceps head 1a and the forceps tail 1c, the forceps body 1b and the forceps head 1a are sequentially connected in a Z shape; a push rod 2 is arranged on the forceps body 1b of each forceps holder 1, one end of the push rod 2 is rotatably connected with the forceps body 1b, and the other end of the push rod 2 is rotatably connected with the pushing seat 6.
The handle 9 is internally provided with a rechargeable battery which supplies power to the motor 7, the handle 9 is provided with a bidirectional switch 10, and the bidirectional switch 10 is used for controlling the motor 7 to rotate forwards, reversely or stop. The end of the screw rod 5 close to the clamp 1 is provided with a bulb 4, the handle 9 is further provided with a press switch 8, and the bulb 4 is electrically connected with the rechargeable battery and the press switch 8. Of course, the light bulb 4 is also powered by a rechargeable battery.
As shown in fig. 1, the side of the binding clip 1a remote from the end of the binding clip 1b and close to the threaded spindle 5 is recessed into the binding clip 1 a. The operation principle of the vaginal dilator in the present application will be described below with specific embodiments.
The main working position of the vaginal dilator is still on the two jaws 1. The two forceps 1 are closed and then extend into the vagina, and then the two forceps 1 are symmetrically opened to stretch the vagina of the patient. Since the jaws 1 are distracted from the vaginal annotation to be able to provide an operating space for the operation. Therefore, the tail 1c, the body 1b and the head 1a of the clip 1 are connected in sequence in a zigzag shape. The forceps 1 are zigzag-shaped to provide an operable space for a surgical operation, for example, a surgical instrument or a therapeutic device can be inserted into a vagina from a side surface of the housing 3 in a direction of the forceps head 1a of the forceps 1. This is also a problem not considered by many current market vaginal dilators, as with the configuration shown in fig. 2.
The two jaws 1 of the vaginal speculum are driven to rotate by a motor 7 driving a screw 5, a pushing seat 6 is driven to move by the screw 5, and the pushing seat 6 drives the two jaws 1 to open or close by a push rod 2. When the operation is completed, if the two jaws 1 are closed directly, it is likely that the portion of the forceps head 1a will pinch the human tissue inside the vagina. Therefore, in the optimized scheme, the side of the clamp head 1a, which is far away from the end of the clamp body 1b and close to the screw rod 5, is recessed towards the inside of the clamp head 1 a. The structure is designed to avoid the above-mentioned situation, and the doctor can operate the operation without worrying about the problem. The curved handle 9 is also very suitable for the doctor to handle. In the case of the straight handle 9, the physician also needs to bend his wrist to accommodate the vaginal anatomy of the person during operation. The curved handle 9 is more convenient for the doctor to master the operation scale.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
