Abstract

The utility model relates to an operation device which is used for cure of fistula, in particular to cure of anus fistula. The utility model is characterized in comprising a micro motor (1), milling cutter bar (5) and milling cutter head (9); the milling cutter head (9) is threaded connected with one end of the cutter bar (5), and the milling cutter of the milling cutter head (9) is faced to the micro motor (1), and the other end of the cutter bar (5) is clipped into and fixed on the motor-hold-bar-head of the micro motor (1). Adopting the structure, the diameter of the milling cutter head is small and corresponding with the shape of the fistula; operators just need find the outer cut of the fistula; the milling cutter head rotary cuts from inner cut to outer cut; the rotation and reverse rotation of the milling cutter head is under the control of the micro motor, and the cut is tiny and the treatment is fast.

Description

Fistula milling device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates to a kind of especially operating theater instruments of anal fistula of fistula for the treatment of specifically.

Background technology

At present the treatment fistula especially the anal fistula Therapeutic Method mainly contain following several: 1, fistulotomy, 2, anal fistula cuts to scrape and take off art, 3, anal fistula cuts and add the hanging wire art, 4, needle knife therapy anal fistula art, 5, play semi-annular jade pendant shape silk cutter and stir and cut art.Weak point: incision is bigger to perianal tissue injury, and be difficult to treat high anal fistula, if use it, promptly easily cause anus to lose some normal physiological function, easily cause anal incontinence and wound healing time longer again, other method is then treated anal fistula and is all existed indication limitation is arranged, or treatment anal fistula is not thorough.

The utility model content

The purpose of this utility model is to provide the Fistula milling device that a kind of wound is little, treatment is fast.

To achieve these goals, the technical solution of the utility model is: Fistula milling device, it is characterized in that it is made up of micromachine 1, milling arbor 5, milling head 9, and an end of milling arbor 5 is threaded with milling head 9, and the milling cutter 11 of milling head 9 is towards micromachine 1; The other end of milling arbor 5 snaps in the motor of micromachine 1 and holds bar head 8 internal fixation under the arm.

This utility model adopts said structure, and the diameter of milling head 9 is less, and corresponding with the fistula shape, only need find the interior collar extension of fistula, and milling head to the rotary-cut of collar extension direction, is controlled its rotating by micromachine from internal orifice, and its wound is little, and treatment is fast.

This utility model characteristics:

1, belong to the invasive operation: carry hardly and hinder fistula normal structure structure on every side, thus influence the normal physiological function of anus hardly, and meet the developing direction and the trend of world today's surgery.

2, can treat various anal fistula, even the treatment that can solve the anal fistula operation brings epoch-making change; Also can treat the fistula disease in other training fields, as areola of breast fistula, preauricular fistula etc.

3, postoperative wound healing than in the past more any fistula Therapeutic Method all fast.

The specific embodiment

Embodiment 1:

As shown in Figure 1, Fistula milling device, it is made up of micromachine 1, milling arbor 5, milling head 9, and an end of milling arbor 5 is threaded with milling head 9, and the milling cutter 11 of milling head 9 is towards micromachine 1; The other end of milling arbor 5 snaps in the motor of micromachine 1 and holds bar head 8 internal fixation under the arm.

As shown in Figure 1, described micromachine 1 is provided with dextrorotation button 2, derotation button 3, supply socket 4, motor and holds bar head 8 under the arm, and motor is held under the arm on the axle that bar head 8 is positioned at micromachine 1.

As shown in Figure 2, described milling arbor 5, one ends are bar head 7, and bar head 7 is provided with external screw thread, and match with the internal thread hole 12 of milling head 9; The other end of milling arbor 5 is a base 6, and base 6 is circular, which is provided with locator card 15, and all around each one of locator card 15 is flat oval handle shape and semicircle depression embedding structure mutually, and base 6 can snap in the motor of micromachine 1 and hold 8 internal fixation under the arm.

As Fig. 6, shown in Figure 7, described milling head 9 is made up of milling cutter seat 10, milling cutter 11, and milling cutter seat 10 is cylindrical, and milling cutter seat 10 is provided with three slitting milling cutters 11, and milling cutter seat 10 central authorities have internal thread hole 12, and internal thread hole 12 matches with external screw thread on the bar head 7; Blade 13, the knife edge 14 are arranged on the milling cutter 11, and the knife edge rotates toward the clockwise direction, and the overall diameter that milling cutter 11 is formed is slightly larger than the diameter of milling cutter seat 10.

As Fig. 6, shown in Figure 7, the diameter of described milling head 9 is 4-8mm, and the diameter of its milling cutter seat 10 is 3.5-7.5mm, and internal thread hole 12 apertures are 2mm or 4mm.

Milling head is straight to be respectively 4,5,6,7 through (φ), 8mm, promptly is made into the milling head of five models that vary in size.

Micromachine 1 is the micromachine of (XB---900 types) hand electric chasing tool of Ningbo Qing Feng tools factory production.
