Description

Knife type vagina separating and cutting scissors

Technical Field

The utility model relates to a medical surgical scissors, in particular to a knife-type vaginal separating scissors.

Background

Hysterectomy is a gynecological operation of targeted quality, in the process of hysterectomy, the uterus is in a free state and needs to be excised from the top end of a vaginal fornix part from an abdominal opening of a patient, and when the vagina is excised in hysterectomy, the operation of detaching the vagina is inconvenient and even difficult because the abdominal opening and a vaginal cutting surface have an angle and the pelvic space of the patient is small. Therefore, when ordinary medical scissors are used, the scissors need to be broken for many times in most cases, and the cutting surface is irregular. And because the visual field at the bottom of the abdominal cavity is poor, fine tissues can fall off after multiple times of shearing, other normal tissues are polluted, the tumor is planted again, the operation of a patient is incomplete, and the recurrence is easy. On the other hand, the multiple separation can also make the following suture difficult, the suture surface is irregular, the prognosis of the patient is not good, the scar healing is difficult, and the recovery time and the economic burden of the patient are increased.

Further, the inner side and the outer side are provided with reinforcing angle ribs; the length ratio of the blade part to the shear handle is 1: 6-12. The arrangement of the reinforcing angle ribs can improve the bending rigidity and ensure the fitting degree of the two cutting edges, so that the separation effect is improved, and the length ratio of the cutting part to the shearing handle is controlled according to the moment relation, so that the purpose of increasing the shearing force is achieved.

Further, the pivot still including T type axle, nut and the crooked gasket that has the round cap, and the supporting screwing device of pivot, the round cap of supporting T type axle can be cut at one of them and set up the elliptical aperture on the handle, make the utility model discloses constitute the detachable structure, the nut include two recesses, screwing device include two protruding nails and oval rotatory handle, protruding nail and recess cooperation are used for screwing the unscrewing pivot. Can dismantle pivot structure can make things convenient for to cut thoroughly cleaning and disinfecting from cutting, and the device of screwing of oval rotatory handle conveniently compresses tightly the screw shaft, overcomes the defect that non-forward pressure leads to easily taking off power to bump the hand when conventional long handle is rotatory.

Compared with the prior art, the utility model discloses a knife formula vagina is from cutting off and is cut, changes the angular relation of cutting handle and cutting part through the design kink to doctor's smooth operation enters into from the position of breaking when making things convenient for the operation. Through designing special cutting part, its whole is circular or oval, does not have any sharp angle and avoids the risk to patient's secondary injury, and the blade is for surrounding shape pitch arc simultaneously, conveniently fixes the shearing position. Different rotating shaft hole positions are designed according to different requirements on the moment structure, different moment sizes are output, and the cutting edge opening and closing sizes are output, so that the novel rotary cutting tool is suitable for various different use environments. Furthermore, through the design of the position of the rotating shaft hole, the structure of the blade part and the matching of the reinforcing angle rib at the bent part effectively ensure the output shearing force and the separation effect, finally achieve the purposes of smooth incision and separation of one incision, reduce the operation difficulty, reduce the operation time and also reduce the adverse effect on patients.
