Abstract

The invention discloses a locking type drill bit protector which comprises a locking lever, a sleeve and a handle. The locking type drill bit protector is characterized in that the locking lever, the sleeve and the handle are sequentially connected with one another, and external left-handed threads on the locking lever are matched with internal left-handed threads of the sleeve; a rotary cap is arranged on the locking lever and can rotate, so that the locking lever is linked and can be optionally vertically adjusted in the sleeve via a sleeve opening; a drill bit through hole in the locking lever is directly perforated through the sleeve. The locking type drill bit protector has the advantages that when the locking type drill bit protector is used in 31 cases of limb long tubular fracture steel plate internal fixation surgery, each drilling procedure can be completed at one step, the peripheral tissues of patients can be protected, the drilling depths can be accurately locked, injury to lateral tissues of the patients due to sudden perforation are prevented in all the cases, the locking type drill bit protector can be operated easily and safely, and the accuracy rate of the locking type drill bit protector reaches 100%.

Description

Locking-type bit protector

Technical field

The present invention relates to a kind of Medical surgical bit protector, especially relate to a kind of can be by the locking-type bit protector of extremity fracture open reduction internal fixation operation.

Background technology

At present; the bit protector using in known extremity fracture open reduction internal fixation operation is in boring procedure; can only protect around drill bit; often to rely on the accurate assurance of both hands for the assurance of boring the saturating side seam cortex degree of depth; careless slightly; injured nerve, blood vessel can cause the damage of offside tissue, if can cause serious consequence.

Summary of the invention

Often to rely on the accurate assurance of both hands, careless slightly meeting to cause that offside tissue injury can cause the deficiency of serious consequence in order to solve known bit protector for the assurance of boring the saturating side seam cortex degree of depth, the invention provides a kind of locking-type bit protector.

The technical solution adopted for the present invention to solve the technical problems is a kind of locking-type bit protector, comprise securing rod, sleeve pipe, handle, it is characterized in that: described securing rod, sleeve pipe and handle are connected in turn, the interior anti-silk that outer anti-silk and the sleeve pipe having on described securing rod has matches; On described securing rod, have turncap, turn turncap is interlocker fixed pole by sleeve opening random up-down adjustment in sleeve pipe; The straight-through sleeve pipe of bit bore that described securing rod has.

The invention has the beneficial effects as follows; the present invention is in conjunction with clinical 31 routine long bone fracture steel plate internal fixation operations; boring procedure all once completes; not only can protect surrounding tissue; more can accurately lock drilling depth; the unexpected Zuan Toushi offside of none example generation tissue injury, simple to operate, safety, accuracy rate 100%.

Detailed description of the invention

In the drawings, a kind of locking-type bit protector, comprises securing rod 4, sleeve pipe 7, handle 6, it is characterized in that: described securing rod 4, sleeve pipe 7 and handle 6 are connected in turn, and the interior anti-silk 8 that outer anti-silk 3 and the sleeve pipe 7 having on described securing rod 4 has matches; On described securing rod 4, have turncap 2, turn turncap 2 is interlocker fixed pole 4 by sleeve opening 5 random up-down adjustment in sleeve pipe 7; The straight-through sleeve pipe 7 of bit bore 1 that described securing rod 4 has.

Using method:

First electric drill head is fixed, the reserved about 3.1cm+dcm+ecm of the length of the bit, d is long bone fracture section maximum gauge, e is steel plate thickness.To be fixed as example in clavicular fracture open reduction steel plate, as clavicular fracture section maximum diameter d=2cm, reconstruction plate thickness e=0.2cm, the about 3.1cm+2cm+0.2cm=5.3cm of drill bit length in reserve.By securing rod 4 of the present invention with in the complete precession sleeve pipe 7 of sleeve opening 5; electric drill head enters from sleeve opening 5; after the reduction of the fracture, first hole at steel plate side; after arriving at offside cortical bone, clockwise rotate turncap 2; making the turncap 2 on securing rod 4 tops is 2mm with the distance of electric drill; detect offside cortex thickness of bone; boring is sent a telegraph to bore and is contacted with securing rod 4; in the time boring saturating offside cortical bone; even if electric drill drives securing rod 4 to turn clockwise; also prolongation protector is made drill bit away from, needn't worry to bore suddenly thoroughly and not stop in time to bore and injure offside tissue.

Claims (3)

1. a locking-type bit protector; comprise securing rod (4), sleeve pipe (7), handle (6); it is characterized in that: described securing rod (4), sleeve pipe (7) and handle (6) are connected in turn, the interior anti-silk (8) that outer anti-silk (3) and the sleeve pipe (7) having on described securing rod (4) has matches.
2. locking-type bit protector according to claim 1; it is characterized in that: on described securing rod (4), have turncap (2), turn turncap (2) is interlocker fixed pole (4) by sleeve opening (5) random up-down adjustment in sleeve pipe (7).
