Embodiment Construction

[0011] In the figure, a locking drill bit protector includes a locking rod 4, a sleeve 7, and a handle 6. It is characterized in that: the locking rod 4, the sleeve 7 and the handle 6 are connected in sequence, and the The external anti-wire 3 and the internal anti-wire 8 of the casing 7 are consistent; the locking rod 4 has a rotating cap 2, and the rotating rotating cap 2 is linked to the locking rod 4 through the casing port 5 on the casing 7. The inside can be adjusted up and down at will; the drill hole 1 provided by the locking rod 4 goes straight through the casing 7 .

[0012] Instructions:

[0013] First fix the electric drill bit, and reserve a drill bit length of about 3.1cm+dcm+ecm, where d is the maximum diameter of the fracture segment of the long tubular bone of the extremities, and e is the thickness of the steel plate. Taking open reduction and plate internal fixation of clavicle fractures as an example, if the maximum diameter of the clavicle fracture is d=2...

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

technical field [0001] The invention relates to a medical surgical drill bit protector, in particular to a locking drill bit protector capable of open reduction and internal fixation of limb fractures. Background technique [0002] At present, the known drill protectors used in open reduction and internal fixation of extremity fractures can only protect the periphery of the drill during the drilling process, and the grasp of the depth of the drilled side cortex often depends on the precise grasp of both hands, which is a little careless , can cause damage to the contralateral tissue, and if the nerves and blood vessels are damaged, it can lead to serious consequences. Contents of the invention [0003] In order to solve the problem that the conventional drill bit protector often relies on the precise grasp of both hands to grasp the depth of the drilled side cortex, and a little carelessness will cause damage to the contralateral tissue and lead to serious consequences. Th...
