Technical field
This utility model relates to the external guiding sight of a kind of minimally invasive spine surgical.
Background technology
Past minimally invasive spine surgical puncture technique is only with the operator personal space imagination and puncture experience, do not have guiding sight can by guiding, puncture direction will definitely not to cause in body the vital tissue organ injury such as neural blood vessel, that is, mainly there are the following problems for existing vertebral column minimally invasive puncture technique:
1. puncture need with personal experience and space imagination in the past, and the point of puncture according to space imagination punctures, and blindness is larger;
2. blindly puncture easily causes vital tissue impaired organ;
3. blindly puncture, the inaccurate waste in puncture direction operating time reduces operator patience and surgical quality;
4. blindly puncture, puncture direction is inaccurate increases perspective number of times, infringement patient and operator.
Utility model content
The purpose of this utility model is exactly to solve the problem, and provides a kind of and improves puncture accuracy and efficiency, save the external guiding sight of minimally invasive spine surgical of operating time.
To achieve these goals, this utility model adopts following technical scheme:
The external guiding sight of minimally invasive spine surgical, it comprises:
Travelling carriage (1), it has the leading truck body (10) extended linearly, the vertical pipes structure (11) being located at a leading truck body end, guide groove structure is established in described leading truck body, the hole horizontal of this vertical pipes structure arranges and the bearing of trend in this hole is mutually vertical with leading truck body bearing of trend, and described vertical pipes vibrational power flow has and the first vertical puncturing positioning needle being installed on vertical pipes structure can be entered line-locked lock(ing) bolt (4);
The universal guiding can slided along leading truck body aims at thimble assembly, it comprises the slide bolt (2) being installed on guide groove structure, this slide bolt has and is arranged in guide groove structure and bolt guiding foot (20) of band external thread structure, leads the vertically arranged aiming sleeve structure (21) of foot with bolt, this aiming sleeve structure is provided with cover (5), this bolt guiding foot is provided with the knob (3) be mated, and described cover is provided with and can will be installed on the lock(ing) bolt of the puncture needle locking of cover.
Further, described leading truck is as flat rod-like structure.
Further, described leading truck body has graduated structure.
Further, described vertical pipes vibrational power flow is in the L shape head of leading truck body, and the width of this vertical pipes structure is greater than the width of leading truck body.
This utility model has following beneficial effect: the external guiding sight of minimally invasive spine surgical, and it is saddle with a scale, one end for band vertical pipes, be used for connect reset puncture needle, the other end is adjustable universal guiding diopter, be used for biopsy needle guide puncture reach target spot.This product design is reasonable, novel structure, uniqueness, and produce processing simply, clinical manipulation is very convenient.

Detailed description of the invention
The technological means realized to make this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth this utility model further.
As shown in figs. 1-11, the external guiding sight of minimally invasive spine surgical, it comprises: travelling carriage 1, slide bolt 2, knob 3, lock(ing) bolt 4, cover 5.
Wherein, described travelling carriage 1, it has the leading truck body 10 extended linearly, be located at the vertical pipes structure 11 (the sleeve pipe inner core of different inner diameters can be designed and allow that the puncture needle of different inner diameters smoothly passes) of a leading truck body end, this leading truck is as flat rod-like structure and this leading truck body has graduated structure, guide groove structure is established in described leading truck body, so that carried out displacement by guide along this guide groove structure, the hole horizontal of this vertical pipes structure arranges and the bearing of trend in this hole is mutually vertical with leading truck body bearing of trend, described vertical pipes vibrational power flow has and the first vertical puncturing positioning needle being installed on vertical pipes structure can be entered line-locked lock(ing) bolt 4, this lock(ing) bolt stretches into from the bottom of vertical pipes structure, can find out at Fig. 3 ', the hole of vertical pipes structure has an aperture arranged for lock(ing) bolt of radial arrangement.
The universal guiding can slided along leading truck body aims at thimble assembly, it comprises the slide bolt 2 being installed on guide groove structure, this slide bolt has the bolt guiding foot 20 being arranged in guide groove structure and being with external thread structure, to lead the vertically arranged aiming sleeve structure 21 of foot with bolt, this aiming sleeve structure is provided with cover 5 (can design the sleeve pipe inner core of different inner diameters and allow that the puncture needle of different inner diameters smoothly passes), the puncture needle pilot hole bearing of trend of cover can leading truck body place plane be parallel, this bolt guiding foot is provided with the knob 3 be mated, by adjustment knob, the puncture needle pilot hole of cover can carry out comprehensive adjustment in the horizontal plane, to adapt to the needs of performing the operation, described cover is provided with and can will be installed on the lock(ing) bolt of the puncture needle locking of cover.
See Fig. 2-3, described vertical pipes vibrational power flow is in the L shape head of leading truck body, and the width of this vertical pipes structure is greater than the width of leading truck body.
Minimally invasive spine surgical often needs Needle localization, for reducing puncture time, reducing damage and radiation number of times, improves operation precision, ad hoc this guider of meter.
First, according to the posterior pedicle articular process puncture technique of body surface bone mark and grasp, first reach position close to target spot as articular process with the capable rear vertical puncture of Kirschner wire with a scale, perspective confirms tip position.
Then, external guiding sight is installed on Kirschner wire with a scale, opens 10-14cm according to requirements of operation guider is other, and determine the position of needle point according to perspective, determine the locality of target spot, the direction of calibration guiding sight is to determine the direction to target spot inserting needle and the degree of depth.
Finally, reach predetermined altitude at the good guider frame of body installation calibrating, combine perspective along the direction inserting needle that guider frame is determined and confirm that progressively penetrating puncture needle reaches predetermined target spot, complete target spot puncture, the operation to make arrangements for surgery (is removed puncture needle core, is squeezed into seal wire reach precalculated position along Puncture needle sleeve.Remove Puncture needle sleeve, guider frame and guide pin with a scale, stay seal wire to complete every operation technique.)
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme belonging to this utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
