Description

Orthopedic surgery guider
Technical Field
The utility model relates to the field of medical equipment, concretely relates to orthopedic operation director.
Background
The orthopedic surgery guider is specially an auxiliary device for bone setting, the bone setting is realized by connecting a fracture part through a screw, when the screw is driven into a bone, firstly, the nailing position and the nailing direction need to be accurately determined, and after the position and the direction are determined, the depth of a bone perforation (usually, a drill is adopted for perforation) needs to be accurately measured, so that the length of the screw is determined, and the specified length error is not more than 1 mm. In this process, there are major problems including the following:
firstly, the punching position can be easily confirmed, but in the punching process, because the bone is hard, the drill bit vibration can cause the drill angle and the drill point of the drill bit to frequently deviate during punching; secondly the vibrations of drill bit still when leading to the drill bit to punch at the bone face, skid and make the drill bit can take place spiral rotation, overlap the drill way greatly, not only harmd the bone, also insecure to driving the screw interlock.
Secondly, when the orthopedic surgery is performed, the wound needs to be small, meanwhile, the surgery is performed by single-side operation, if the secondary injury to the patient is large due to the operation on two sides, the probability of sequelae left after the surgery is also large, and the family members of the patient also contradict the treatment scheme of the operation on two sides.
Measuring the depth of the punched hole is difficult, because the depth of the affected part measured by the current guider is the thickness of tissues including fat and the like, the measured data subtracts the thickness of the fat, the thickness of the fat cannot be measured and can only be estimated, and the error is easy to exceed the requirement of 1 mm.
The fracture forms are various, such as oblique fracture, bifurcation fracture, comminuted fracture and the like, which means the diversity of the opening directions on the bone, and the requirement also puts higher requirements on the guider.
The prior art which is specially used for orthopedic guides is also disclosed, for example, the technology disclosed by the application number of CN201721622352.6, namely an orthopedic surgery precision adjustable drill guide, the principle of which is to clamp, measure and position a fracture part for punching; however, the usability is poor, firstly, the number of surgical incisions is not considered, according to the technical scheme disclosed by the invention, the opening depth can be accurately measured only by opening at two sides of an affected part, and if the opening depth measured by the patient is the thickness containing fat and other tissues, although the measurement reading is accurate, the measured data is not real hole data and still needs estimation and calculation. Secondly, the bone pieces at different affected parts have different sizes, and the screws used have different thicknesses, which means that the drilled holes have different diameters, and for thinner drill bits, the drill bit still faces the problem of slipping, so that the drill bit cannot be effectively restrained. Finally, for the oblique fracture of the bone, a scheme of oblique perforation is needed for perforation, and for the situation, the fractured bone cannot be effectively clamped, and the guide device slips and loosens due to the vibration of the drill bit, so that the guide effect is lost.
Disclosure of Invention

Preferably, the probe and the main ruler guide tube or the vernier guide tube are installed in a clearance fit mode and are locked and limited through the locking bolt.
Preferably, the sleeve pipe and the main scale guide pipe or the vernier guide pipe are installed in a clearance fit mode, at least one sleeve pipe is arranged, the outer diameter of each sleeve pipe is consistent, the inner diameter of each sleeve pipe is different, different sleeve pipes are used for extending drill bits with different thicknesses, and the problems that the drill bits slip and shift cannot occur when the drill bits are hit on bones are solved.
Preferably, the main ruler guide pipe and the vernier guide pipe are consistent in specification, and the specification comprises parameters such as length, outer diameter, inner diameter and inclined plane sharp teeth.
Preferably, when the probe is arranged in the main scale guide tube, the tip of the probe is opposite to the sharp corner of the vernier guide tube by a zero distance; when the probe is arranged in the guide tube of the vernier, the tip of the probe is opposite to the sharp corner of the guide tube of the main scale at a zero distance.

Preferably, the tail end of the sleeve is provided with a clamping edge for limiting the position when the sleeve is installed in place, and the length of the sleeve is shorter than that of the main ruler guide tube or the vernier guide tube.
The beneficial effects of the utility model reside in following:
the traditional guider has small span and poor adjustability, and the operator can operate in a small space when performing a large limb operation. The design guider has large measuring span and good adjustability. The measuring span can be freely adjusted according to the requirements of the operator, which is more beneficial to the limb measurement of different radial lines and orientations, so that the operator can measure the limbs with ease.
The reading area is separated from the working area, the debugging of the working area drags the reading area to slide, the length of the screw required by preset drilling at any time point can be obtained, and the drill can inform an instrument nurse to prepare the screw with the preset length before rotating the hole, so that the operation time is saved. And a secondary depth sounding link is not needed, so that the artificial measurement error is reduced.
The measurement area is an axisymmetric appearance, the nail feeding direction and the nail discharging direction have no primary and secondary division, any nail feeding direction is also the nail discharging direction, the contact point of the zero returning guide needle and the bone surface is the nail discharging point, and the contact point of the inclined surface of the other side guide sleeve and the bone surface is the nail feeding point by default, so that the drilling direction can be changed arbitrarily according to the personal operation habit of an operator and the position requirement of a patient. No matter from which side the hole is drilled, the reading habit of the measuring zone is not changed.
Compared with the traditional guiding cannula which is cut open, the probe has less wound and less scars when stabbed to the bone surface of the bone through the skin.
The traditional orthopedic surgery punching sequence is as follows: the operator uses the guider to position, the operator punches the hole, the operator makes depth measurement, the nurse finds the screw and measures the length of the screw, and the screw finding and the screw measuring are sequentially completed in time, each link is lack of one link, and the medical care work is mutually restricted. The guider has time superposition in the operation sequence, and after positioning, the accurate bone punching depth (the required screw length) can be directly read out, so that an operator does not need to consciously measure the nail hole depth; the nurse just can begin to transfer the matching screw when punching to the art person and measure the screw, confirms length again, and both accomplish this process simultaneously, and the nurse also transfers the screw out after punching, then directly packs the screw into the bone hole of beating. Therefore, the medical care work does not block hands, and the operation time is finally shortened.
The pressure intensity between the outlets of the main ruler guide pipe and the traveling ruler guide pipe and the bone surface is increased by adopting the inclined plane sharp tooth design, so that the drill bit is prevented from deviating due to the shaking of the electric drill. Conventional guides do not have this characteristic.
Traditional director can only be fit for the forward direction of punching, to the slant punch, and the clamping effect between the bone is poor, especially when the electric drill punches, vibrations very easily lead to the director to take place to shift, needs the art person's full power to the accuse drill bit reduction vibrations.
