Abstract
The utility model is related to a kind of medicine equipment, and specially orthopedic spinal Minimally Invasive Surgery is bored, including service pipe, trepan and handle, described trepan front end is bistrique, and rear end connection handle, trepan rear end is also equipped with loop coil, there is external screw thread on trepan, described loop coil is connected on trepan by internal thread.The orthopedic spinal Minimally Invasive Surgery that the utility model is provided is bored, and the excessive operation risk for causing injury neural is stretched into after osteoclastic matter it is possible to prevente effectively from boring, facilitates surgical to use.
Description
Technical field
The utility model is related to a kind of medicine equipment, and specially orthopedic spinal Minimally Invasive Surgery is bored.
Background technology
Orthopedic spinal Minimally Invasive Surgery bore be a set of apparatus being applied in orthopedic spinal Minimally Invasive Surgery a part, including three
Individual part：Service pipe, trepan and handle.Service pipe is UNICOM's vertebra and an extraneous passage, and trepan is by work
Make pipeline and reach vertebra trepan, effect is to grind off a part of vertebra sclerotin of stop to be performed the operation.In surgical procedure, bone
Be exactly softer canalis spinalis after matter is worn out, trepan has one kind and fallen through sense grinding off when sclerotin enters canalis spinalis, but at this time
Operation must be careful, if somewhat accidentally trepan may in a flash entered excessively hurt nerve in entrance
Root.
Utility model content
For above-mentioned technical problem, the utility model offer is a kind of can to pierce the orthopaedics of depth with easy and effective control trepan
Minimally invasive spine surgical is bored, and lowers operation risk.
Specifically technical scheme is：
Orthopedic spinal Minimally Invasive Surgery is bored, including service pipe, trepan and handle, and described trepan front end is bistrique, rear end
Handle is connected, trepan rear end is also equipped with loop coil, trepan having external screw thread, and described loop coil is connected to trepan by internal thread
On.
Loop coil on trepan by screw thread rotation, can be with adjusting position, so as to control the length between loop coil and trepan bistrique
Degree, so as to remind the deep length of operation trepan, to prevent go deep into it is long hurt nerve root, when bistrique does not completely penetrate through sclerotin,
Loop coil can be rotated, the propulsion of suitable length is released again, until penetrating.
Further optimization design is that described trepan is the bits groove for also having spiral in hollow structure, trepan front inner wall.
Skeletal detritus under grinding can enter the bits groove of spiral.
The orthopedic spinal Minimally Invasive Surgery that the utility model is provided is bored, and is excessively caused it is possible to prevente effectively from boring and being stretched into after osteoclastic matter
The operation risk of nerve is injured, facilitates surgical to use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described with reference to the drawings.
As shown in figure 1, orthopedic spinal Minimally Invasive Surgery is bored, including service pipe 2, trepan 1 and handle 4, before described trepan 1
Hold as bistrique, rear end connection handle 4, the rear end of trepan 1 is also equipped with loop coil 3, trepan 1 having external screw thread, and described loop coil 3 passes through
Internal thread is connected on trepan 1, and described trepan 1 is the bits groove 5 for also having spiral in hollow structure, trepan front inner wall.
External screw thread is set with trepan, and increases a loop coil 3 that can be rotated on external screw thread for being about 20mm, it is interior
Diameter is identical with trepan 1, about 7.5 millimeters, can be adapted to above the screw thread on trepan 1.
It is starting point since front end, the external screw thread on trepan 1 is started in 180mm place, i.e., from beyond service pipe 2
15mm place start, external thread length about 40mm, loop coil 3 is in lowest part, and trepan 1 is beyond the length of service pipe 2
15mm.When loop coil 3 is in highest point, trepan 1 can be 35mm beyond service pipe 2, thus there is a movable scope, sclerotin
Because individual difference typically can all be fluctuated in the range of this, when 15mm is not enough to penetrate sclerotin, appropriate rotation screw thread rises it
High 5mm, so both can make trepan get into deeper position, and can also avoid boring stretching into after osteoclastic matter excessively causes imprudence to be hindered
Evil nerve.
Eye-catching scale is shown every a segment mark, such as initial 180mm on external screw thread, 185mm etc. is in order to operator
Preferably judge the length that trepan is stretched into
The profile of loop coil 3 can be cylinder, or other shapes, such as shape of similar handle.
Bistrique is anticlockwise, when trepan 1 rotationally clockwise, and the bistrique sclerotin that can rub is operated.Ring
The effect of bits groove 5 for boring spiral on 1 front end outer wall is when trepan 1 grinds sclerotin, bone bits is entered along screw thread in trepan 1
Portion, and the worn out sclerotin of trepan 1, when trepan 1 is taken out, can take out bone bits together, bone bits are not fallen out in human body.
Because trepan 1 is work clockwise and then sclerotin is worn out, therefore from the angle of handle 4, bits groove 5 is counterclockwise.
Claims (2)
1. orthopedic spinal Minimally Invasive Surgery is bored, including service pipe (2), trepan (1) and handle (4), described trepan (1) front end is
Bistrique, rear end connection handle (4), it is characterised in that described trepan (1) rear end is also equipped with loop coil (3), and trepan has on (1)
External screw thread, described loop coil (3) is connected on trepan (1) by internal thread.
2. orthopedic spinal Minimally Invasive Surgery according to claim 1 is bored, its feature exists：Described trepan (1) is hollow structure,
There is the bits groove (5) of spiral in trepan front inner wall.
